FIELD OF THE INVENTION

The object of the present invention consists of a package and process of making the same. The package, object of the present invention, can for example find an application in the pharmaceutical and cosmetics fields. However, the package can find an advantageous application also in the food field for packaging food and, particularly, confectionery products and also in the cigars and cigarettes fields for packaging the same. The package, object of the present invention, finds an advantageous application in all the fields requiring, from the safety point of view, to prevent children from opening the package itself. Moreover, the package can find an application in all the fields in which products are packaged in a way which ensures the closure of the package itself, and provides a feature enabling to evidence a possible tampering of this latter.

STATE OF THE ART

As it is known box-shaped packages configured for being easily reversibly opened and reclosed are commercially available. Nowadays, such packages are used for containing a wide range of products such as, for example: drugs, cosmetics, food products (confectionery products, for example), cigars, and cigarettes.

Generally, such known packages comprise a container of paper material having a box-shape, exhibiting two accesses longitudinally opposite to each other. At each access, the container comprises a tab rotatively movable with respect to the container itself between an open condition wherein the tab is distanced from the access, and a closed condition wherein the tab is inserted in the container and occludes the access. The tab, in the closed condition of the container, exhibits a "L" shape wherein an inserting portion of the tab itself inside the

- l - container, faces and contacts a front wall of this latter.

The package can comprise one or more wrappers - insertable and extractable from the container - in which the products are disposed (the wrapper can comprise a blister supporting a plurality of pharmaceutical-type products, for example) or the products are directly housed in the package (without any wrapper): the "loose" products are inserted in the package in the same way used nowadays for cigars and cigarettes.

However, it is noted that such known types of packages can be easily openable by children which therefore can come in contact with elements which are potentially hazardous to them. It is also observed that such known packages enable to completely extract the product (a blister containing medicines, cosmetics plastic tubes, and so on, for example) from the package itself: once the product is extracted, there is the possibility of forgetting it outside the package, consequently children can possibly come in contact with potentially hazardous elements.

A further embodiment of a nowadays known package comprises a casing of paper material, having a box-shape; the inside of the casing receives a tray of plastic material which constrains to the inside thereof one or more blisters destined to contain a plurality of products.

The casing exhibits a standard open and close mechanism (the movable "L"- shaped tab is useless in the package); in the closed condition of the package, an engagement portion of the tab extends parallel to a front wall of the container itself.

Contrary to the preceding solutions, the casing of this latter package exhibits, at the opposite longitudinal lateral walls, two slots which are moreover disposed along a diagonal of the casing itself. The tray comprises two projections adapted to be inserted in respective slots of the casing: in the condition, wherein the tray is housed in the casing, the engagement of the projections into the slots prevents the tray itself from being extracted by only pulling the casing itself. If somebody wants to extract the tray from the container, it is necessary to apply a pressure on the projections in order to push them towards the inside of the container itself and cause them to disengage from the slots; at this point, it is possible to extract the tray.

This latter solution has an open mechanism requiring to grasp and handle in a particular way the package, this condition makes arduous to open the same by children.

However, the Applicant has observed that also the just described package is not devoid of limitations and inconveniences. Actually, it is noted that the structure of the package is somewhat complex, this fact adversely affects the manufacturing costs and the cost of the product itself; actually, the package for correctly operating requires a shaped tray of plastic material. Moreover, the particular structure of the tray requires to substantially modify the existing packaging plants used for making standard-type packages; particularly, such modification requires to insert a new closure line, to provide a suitable equipment for forming the tray consequently the manufacturing costs and therefore also the costs of the final product are substantially increased. OBJECT OF THE INVENTION

Therefore, an object of the present invention consists of substantially solving at least one of the inconveniences and/or limitations of the preceding solutions.

A first object of the present invention consists of providing a package exhibiting a simple and compact structure which, at the same time, can: effectively prevent children to gain access and prevent to completely extract the products housed inside it. Moreover, it is an object of the present invention to provide a package exhibiting a highly flexible structure when used.

A further object of the present invention consists of providing a package, advantageously a child-proof package, exhibiting a stable structure capable of ensuring the integrity thereof upon multiple openings and closings of the container itself.

Moreover, it is an object of the present invention to provide a package which can effectively and positively evidence a tampering at the first opening of the package itself, also to sight-impaired people.

An additional object of the present invention consists of providing an associated package which can be readily manufactured at a low manufacturing cost. Specifically, it is an object of the invention to manufacture a package which does not require to modify already existent plants used for making standard-type packages, in order to adapt them to the manufacture of the package object of the present invention.

Then, it is an object of the present invention to provide a fast and extremely flexible process for making a package which can therefore minimize the manufacturing costs.

These and other objects, which will better appear in the following description, are substantially met by a package and associated making process according to what is expressed in one or more of the attached claims and/or following aspects, considered alone or in any combination with each other or in a combination with anyone of the attached claims and/or in a combination with anyone of the further aspects or characteristics described in the following.

DETAILED DESCRIPTION

1 . Package 100

100 generally indicates a package for example useable for containing products, which can find an application in all the fields requiring, for safety reasons, to prevent the package itself from being opened by children; advantageously but in a non-limiting way, the package 100 can further find an application in all the fields which provide to close the package itself and exhibit a safety feature enabling to evidence a possible tampering of this latter.

1 .1 First embodiment of the package 100

A first embodiment of the package 100 comprises a casing 102 made of a sheet material, particularly of a paper sheet material, defining an inner volume 103. Particularly, the casing 102 comprises a predetermined number of lateral walls 104 defining at least one passage opening 105 delimited by a free edge 106; the passage opening 105 is configured for enabling the inner volume 103 to communicate with the outer environment. The attached figures illustrate, in a non- limiting way, a configuration of the casing exhibiting two passage openings opposite to each other, so that the casing 102 can substantially define a conduit or tube laterally delimited by said walls 104 and open at longitudinal ends. Still more particularly, the casing 102 extends between a first and second longitudinal end portions 102a, 102b along a longitudinal development direction of the casing 102 itself; the lateral walls 104 therefore define:

- a first passage opening 105 delimited by a free edge 106 and located at the first longitudinal end portion 102a,

- a second passage opening 205 delimited by a respective free edge 206 and located at the second longitudinal end portion 2b.

See Figures 44 and 45 for example. The attached figures illustrate a preferred but non-limiting configuration of the casing 102, which exhibits a rectangular prismatic shape (the flat lateral walls 104 have a rectangular shape). Actually, the casing 102 exhibits a front wall 104a and a rear wall 104b facing and parallel to each other: the front wall and rear wall are connected to each other by a first and second lateral walls 104c, 104d also facing and parallel to each other. The front wall 104a is distanced from the rear wall 104b; the first and second lateral walls 104c, 104d are also distanced from each other (see Figure 45). The casing 102 exhibits, along a cross-section transversal to the lateral walls, a parallelogram shape, particularly a square or rectangular shape. However, it is not excluded the possibility of making a casing 102 having a different shape, for example a square, trapezoidal shape.

In the first embodiment of the package 1 , the second passage opening 205 of the casing is occluded by a closing system (this system is not illustrated in the attached figures) which can comprise one or more tabs of sheet material glued to each other. De facto, in the first embodiment of the package 100, the casing 102 exhibits a single access to the inner volume 103, represented by the first passage opening 105: the second passage opening is occluded. The casing, at the second end portion 102b, exhibits substantially a bottom wall adapted to prevent the access to the inner volume 103.

In the first embodiment of the package, the casing 102 comprises, at the first end portion 102a, an engagement portion 107 emerging, from at least a lateral wall 104, inside the inner volume 103 for defining a projection (see Figure 14, for example). In such embodiment, the engagement portion 107 is directly constrained, particularly is joined in a single piece, to the free edge 106 of the passage opening 105: the engagement portion 107 emerges from the free edge 106 according to a direction entering the inner volume 103, in other words towards the second passage opening 205 of the casing 102. Still more particularly, the engagement portion 107 is constrained to the front lateral wall 104a of the casing 102 (see Figure 14 again). The engagement portion is movable with respect to the lateral walls 104 by rotating about the free edge 106 to which is constrained. Particularly, the engagement portion 107 is joined in a single piece to the front lateral wall 104a and is rotatively movable with respect to this latter.

The engagement portion 107 comprises at least one tab 107a (Figure 14) of sheet material, particularly of paper sheet material, joined in a single piece to the front wall 104a. At least part of the tab 107a extends along a rectilinear development direction sloped with respect to an extension direction of the front wall 104a to which the tab 107a itself is joined in a single piece. The tab defines - with the front wall to which the tab itself is joined in a single piece - an angle equal to or greater than 1 °, particularly comprised between 1 ° and 15°, still more particularly comprised between 1 ° and 5°; said angle being defined in the inner volume 103 and being subtended between the tab 107a and the front lateral wall 104a.

From the dimensional point of view, the casing 102 defines an inner volume 103 substantially greater than 20,000 mm ³ , particularly comprised between 40,000 and 200,000 mm ³ . However, the casing 102, object of the present invention, can be used for packaging medium-sized products: in such condition, the casing 102 can exhibit an inner volume greater than 500,000 mm ³ , particularly comprised between 800,000 and 1 ,400,000 mm ³ . However, it is not excluded the possibility of using the package 100 for packaging large-sized products; in such condition, the casing 102 can exhibit an inner volume 103 greater than the above specified volumes, for example greater than 10,000 cm ³ but in a non-limiting way.

In the first embodiment of the package 100, the same comprises at least one container 1 of sheet material, particularly of paper sheet material, distinct from the casing 102 and configured for housing at least one product. The container 1 exhibits a predetermined number of lateral walls 4 defining at least one respective passage opening 5 delimited by a respective free edge 6. The passage opening 5 of the container 1 is configured for enabling to insert and withdraw the product from the container 1 . In the first embodiment of the package, the container 1 extends between a first and second end portions 2a, 2b along a longitudinal development direction; therefore, the lateral walls 4 define:

- a first longitudinal passage opening delimited by a free edge and located at the first longitudinal end portion,

- a second longitudinal passage opening delimited by a respective free edge and located at the second longitudinal end portion.

The container substantially defines a conduit or tube laterally delimited by said walls 4 and open at the longitudinal ends. In the first embodiment of the package, the container 1 exhibits a rectangular prismatic shape (the flat lateral walls 4 have a rectangular shape). Actually, the container exhibits a front wall 4a and a rear wall 4b facing and parallel to each other: the front wall and rear wall are connected to each other by a first and second lateral walls 4c, 4d also facing and parallel to each other. The front wall 4a is distanced from the rear wall 4b; the first and second lateral walls 4c, 4d are also distanced from each other. The container exhibits, according to a cross-section transversal to the lateral walls, a parallelogram shape, particularly a square or rectangular shape (see Figures 44 and 46). However, it is not excluded the possibility of making a container 1 having a different shape, for example a square, trapezoidal shape. Advantageously, the container is at least partially countershaped to the casing 102.

In the first embodiment of the package 1 , the first and second longitudinal passage openings of the container 1 are occluded by a closing system (this system is not illustrated in the attached figures) which can comprise one or more tabs of sheet material glued to each other.

In the first embodiment of the package, the container 1 - at the rear lateral wall 4b - comprises at least one seat 91 delimited by at least one stop wall 92 delimiting at least partially the package opening 5 of the container 1 : the stop wall 92 delimiting at least part of the seat 91 further defines at least one stop element 90 which, as it will be better described in the following, is adapted to cooperate with the engagement portion 107 of the casing 102.

Figures 46 illustrates an embodiment of the container 1 comprising - between the first and second lateral walls 4c, 4d - a plurality of seats 91 distanced from each other and aligned along a single direction transversal, particularly normal, to the development direction of the container 1 . Each seat defines a respective stop element 90 and a respective passage opening 5 for withdrawing and inserting a product into the container.

The container 1 is configurable between:

- a first operative position wherein the container 1 itself is at least partially housed in the casing 102 (see Figure 44, for example). In the first operative position, the passage opening 5 (optionally a plurality of passage openings 5) of this latter is at least partially defined inside the inner volume 103 of the casing 102 which - in such first operative position - prevents the product from being inserted and withdrawn from the container 1 ,

- a second operative position wherein the container 1 itself is at least partially disposed outside the inner volume 103 of the casing 102. In the second operative position, the passage opening 5 of this latter is defined outside the casing 102 and is adapted to enable to insert and withdraw the product from the container 1 .

More particularly, in the first operative position, the front and rear lateral walls 4a, 4b of the container 1 face respectively the rear and front walls 104b, 104a of the casing 102. As hereinbefore described, the stop element 90 is defined on the rear lateral wall 4b of the container 1 , which is configured for abutting, in the first operative position, against the engagement portion 107 of the casing 102 for preventing the container 1 from switching from the first to the second operative positions.

Figure 2 schematically shows a condition wherein the container 1 is disposed in the casing 102; particularly Figure 2 illustrates a condition wherein the container 1 is disposed in a condition of maximum insertion inside the casing.

When somebody tries to extract the container 1 from the casing 102, the engagement portion 107 abuts against the stop element 90 of the container 1 as schematically shown for example in Figure 4: fitting the engagement portion 107 with the stop element 90 prevents the container 1 from exiting the casing 102 and therefore from uncovering the passage opening 5. De facto, the incapability of extracting the container 1 prevents the products from being withdrawn from the container 1 .

When the container 1 exhibits a plurality of stop elements 90 (Figure 46), it is noted that each of them is configured for cooperating with the engagement portion 107 of the casing for defining a first operative position.

The attached figures illustrate a preferred but non-limiting embodiment of the invention wherein the seat 91 is delimited by a free edge having a rectangular shape extending along a direction transversal to the prevalent development direction of the container. The seat 91 and consequently the stop element 90 extend along a direction transversal, particularly normal, to the extension direction of the engagement portion 107.

In the first embodiment of the package, the seat 91 and consequently the passage opening 5 of the container 1 , are defined on the rear lateral wall 4b and face the front lateral wall 104 of the casing 102. The container 1 , at least in the first operative position, exhibits the first and second lateral walls 4c, 4d respectively disposed at the first and second passage openings 105, 205 of the casing 102.

As it is for example visible in the schematic views in Figures 2, 4, 6, 7 and 47, the package 100 comprises at least one slot 150 - defined between at least one lateral wall 104 of the casing 102 and at least one lateral wall 4 of the container 1 - configured for enabling, at least in the first operative position, to insert at least one open device 160 adapted to enable to disengage the stop element 90 of the container 1 from the engagement portion 107 of the casing 102 for enabling the container 1 to switch from the first to the second operative positions.

Particularly, the package 100 comprises an open device 160 of sheet material, particularly of paper sheet material, configured for being inserted at least partially, at least in the first operative position, through the slot 150 for enabling to disengage the stop element 90 of the container 1 and the engagement portion 107 of the casing 102.

More particularly, the slot 150 is defined between the lateral wall 104 of the casing directly supporting the engagement portion 102, and the lateral wall of the container 1 , on which the stop element 90 is defined. In the first embodiment of the package 100, the slot 150 is defined between the rear lateral wall 4b of the container 1 and the front lateral wall 104a of the casing.

Advantageously, the slot 150 extends all along the development of the lateral wall 104 of the casing 102 directly supporting the engagement portion 107 as illustrated in Figure 1 , for example.

Figure 6 schematically shows an operative condition in which the open device 160 is inserted, so that is interposed between the stop element 90 and the engagement portion 107 for enabling their disengagement: upon disengaging the element 90 and portion 107 from each other, the container 1 can switch from the first to the second operative positions as illustrated in Figures 7 and 49, for example.

The open device 160 extends along a development direction between a first and second longitudinal portions 160a, 160b (Figure 47). Advantageously, the open device 160 exhibits a width - defined by the maximum distance between said longitudinal portions 160a, 160b - substantially equal to the extension of the container 1 , defined by the maximum distance between the first and second end portions 2a, 2b.

In an embodiment illustrated in Figure 47 for example, the open device 160 comprises a main body 160a and a plurality of transversal distanced blocking elements 161 laterally emerging from the main body according to a direction transversal to the development direction of the device 160 itself; particularly, the distance between two blocking elements 161 immediately consecutive along the development direction of the device 160, is substantially equal to the distance between two immediately consecutive stop elements 90 of the container 1 . Each blocking element 161 being configured for enabling to partially insert the open device 160 for enabling to extract the container to a predetermined passage opening 5. Advantageously, the blocking elements 161 are constrained to the main body 160a by weakening lines adapted to enable to remove (tear) the blocking elements of the main body 160a.

Advantageously, the container 1 can comprise an auxiliary seat 96 defined on the lateral wall 4 itself, on which the stop element 90 is defined; the auxiliary seat 96 being delimited by an edge 97 which defines an auxiliary stop element 95 also configured for cooperating with the engagement portion 107 of the casing 102. More particularly, the auxiliary stop portion 95 - in the first operative portion of the package 100 - is distanced from the opening 105 so that the stop element 90 is interposed between said passage opening 105 and the auxiliary stop portion 95 (see Figure 4, for example).

The auxiliary stop portion 95 is configured for abutting against the engagement portion of the casing 102 for preventing to completely extract the container 1 from the casing 102. De facto, when somebody tries to further extract the container 1 from casing 102 - starting from the second operative position of the package - the engagement portion 107 is configured for being inserted in the seat 96 and abutting against the edge 97 (Figure 7), so that it prevents to completely extract the container 1 from the casing 102.

1 .2 Second embodiment of the package 100

In a second embodiment of the package 100, the same comprises a casing

102 made of sheet material, particularly of paper sheet material, as hereinbefore described with reference to the first embodiment. Unlike the first embodiment, the casing 102 exhibits - as a substitute for the closing system of the second passage opening 205, an occluding system 207 (Figures 1 , 3, 5 and 8). De facto, at the second end portion 102b, the casing 102 comprises an occluding system 207 of sheet material, particularly of paper sheet, engaged with the free edge 206 of the second opening 205.

Therefore, the occluding system 207 is defined oppositely to the passage opening 105. The occluding system 207 is configured for irreversibly closing the second passage opening 205 and therefore preventing to gain access from the outside into the inner volume 103 through said second passage opening 205. In the second embodiment of the package 100, the casing 102 is open only at the first passage opening 105.

The occluding system is configured for blocking the access to the inner volume 103 of the casing 102 through the opening 205 following a first closed condition of the occluding system 207. The system 207, following a first closed condition of the same, is configured for being irreversibly blocked and preventing therefore the same to be opened again.

For a better comprehension of the structure of the occluding system 207, Figures 15 and 16 schematically illustrate a first closing step of the occluding system, at the end of it, the system 207 irreversibly occludes the passage opening 205. Instead, Figures 18 and 19 schematically illustrate the blocked occluding system.

As it is visible in Figure 15, the occluding system 207 comprises at least one tab 208 which exhibits a closing portion 209 directly engaged with and joined in a single piece to the free edge 206: the closing portion 209 is a component of the tab 208 configured for preventing the passage through the opening 205 of the system 207 itself. As it is visible in Figure 15, for example, the closing portion 209 substantially comprises a flat body of sheet material countershaped to the free edge 206 of the opening 205. The attached figures schematically illustrate a preferred configuration of the closing portion 209 exhibiting a rectangular shape completely countershaped to the free edge 206.

The tab 208 comprises an inserting portion 210 disposed inside the volume

103. The inserting portion 210 is joined in a single piece to the closing portion 209, and emerges from this latter: the inserting portion 210 is substantially an extension of the closing portion 209. Particularly, the inserting portion 210, in an operative condition defined after the first closed condition of the occluding system 207, is completely inside the volume 103. As it is visible in Figures 15 and 16, also the inserting portion 210 substantially comprises a flat body of sheet material having, in a non-limiting way, a rectangular shape. As it is visible for example in the cross-section view of Figure 16, the inserting portion 210 extends between a first and second prevalent development surfaces 210a, 210b respectively facing the outside (directly facing the front lateral wall 104a of the casing) and towards the inner volume 103: at least one portion of the first development surface 210a of the inserting portion 210 faces, particularly contacts, directly a portion of a lateral wall 104 (particularly of the front wall 104a). The surface 210a extends at least particularly parallel to the front lateral wall 104a, particularly to a wall 104 opposite to the wall directly connected to the system 207, in other words opposite to the rear wall 104b.

The closing portion 209 and inserting portion 210 exhibit a reciprocal connecting edge opposite to the free edge 206 with respect to the closing portion 209 itself. The inserting portion 210 is configured for defining, according to a cross-section transversal and cooperatively with the closing portion 209, a substantially "L" shape.

More particularly, the closing portion 209 of the tab 208 of the occluding system 207 exhibits a shape delimited by a closed outer perimeter countershaped and substantially identical to the second passage opening 205: the closing portion 209 of the occluding system 207 completely covers the second passage opening 205. As it is visible in Figure 15, the closing portion 209 of the occluding system 207 is devoid of through openings; particularly, the closing portion 209 is joined in a single piece to the inserting portion 210 for defining a single continuous body delimited by a single outer closed perimeter devoid of through openings defined inside said closed outer perimeter.

As it is visible in Figure 15, for example, the occluding system 207 can comprise at least one abutment portion 224 engaged with the free edge 206 of the casing 102 adjacent the tab 209: the abutment portion 224 is configured for being interposed between the inner volume 103 and tab 208 so that it cooperates with this latter in order to have a better blockage of the system 207. The abutment portion 224 substantially comprises a flat tab of sheet material joined in a single piece to the free edge 206 adjacent the closing portion 209. The abutment portion 224 exhibits, in a non-limiting way, a rectangular or trapezoidal shape.

More particularly, the abutment portion 224 is constrained to the free edge 206 so that it can engage at least part of the inserting portion 210 and/or of the closing portion 209 for stably holding the tab 208 in said condition. Advantageously, the container 1 comprises two abutment portions 224 opposite to each other with respect to the tab 208: this latter is interposed between the two abutment portions 224 (Figure 15). In such configuration, the two abutment portions 224 operate symmetrically on the tab 208 and cooperatively with the occluding system 207 for holding stably blocked this latter.

Advantageously, the occluding system 207 is made of a paper sheet material and is obtained by folding; particularly the system 207 is made in a single piece with the lateral walls 104 and particularly is directly connected in a single piece to the front and rear lateral walls 104a, 104b.

More particularly and as it is visible in Figure 15, for example, the occluding system 207 comprises at least one first hooking portion 212, supported by the tab 208 and at least one second hooking portion 213, engaged with the lateral wall (particularly the front lateral wall 104a) of the casing. The first and second hooking portions 212, 213 are stably and irreversibly engaged with each other. Following the first closed condition of the system 207, the casing is substantially in a blocked condition in which the access to the casing 102 at the second passage opening 205 (at the second end portion 102b of the casing 102), is prevented by the engagement itself between the first and second hooking portions 212, 213. The second hooking portion 213 is disposed inside the inner volume 103 and substantially lies in a plane parallel to one of the lateral walls 104. Particularly, the second hooking portion 213 comprises a tab of sheet material, optionally of paper sheet material, extending along a development plane: the tab of the hooking portion 213 comprises a body exhibiting a substantially "C" shape the concavity thereof faces away from the closing portion 209 of the occluding system 207. As it is visible for example in the cross-section view of Figure 16, the tab of the second hooking portion 213 of the occluding system 207 is sloped with respect to the inserting portion 210 facing said second hooking portion 213; particularly, the tab of the second hooking portion 213 of the occluding system 207 exhibits an angle of inclination with respect to the inserting portion 210 facing said second hooking portion 213, less than 20°, optionally less than 10°.

The second hooking portion 213 develops completely inside the volume 103 (is disposed completely inside the casing). The first hooking portion 212 is also disposed completely inside the inner volume 103. Particularly, the first hooking portion 212 is completely contained inside the volume 103 and is distanced from the free edge 206 of the second passage opening: the engagement between the second hooking portion 213 and first hooking portion 212 is defined completely inside the inner volume 103. The engagement between the first and second hooking portions 212, 213 is of an irreversible type; in other words, after a first closed condition of the occluding system is obtained, the first and second hooking portions 212, 213 cannot be disengaged anymore and therefore they cannot define an open condition of the casing 102 at the second end portion 102b. This is possible because the closing portion 209 and inserting portion 210 comprise, as hereinbefore described, solid bodies devoid of openings configured for covering the engagement between the portions 212 and 213: in this way, the hooking portions 212 and 213 cannot be reached in any way from the outside and therefore cannot be disengaged in any way. More particularly, the first hooking portion 212 is engaged, particularly is directly supported, by the tab 208 of 207. Advantageously, the first hooking portion 212 is only supported, but in a non-limiting way, by the inserting portion 210 of the tab 208: the two portions 212 and 210 are advantageously joined in a single piece to each other in order to form a single body, particularly a single sheet of paper material. De facto, the first hooking portion 212 comprises a body of a flat sheet emerging, particularly without interruption, from the inserting portion 210 oppositely to the closing portion 209: the inserting portion 210 is therefore interposed between the closing portion 209 and first hooking portion 212.

The body of sheet material of the first hooking portion 212 extends between a first and second prevalent development surfaces 212a, 212b (Figure 16) respectively facing in the same direction of the first and second surfaces 210a, 210b of the inserting portion 210: the first surfaces 210a, 212a extends, without interruption between them and directly face a same lateral wall 104 (the front wall 104a) opposite to the lateral wall 104 directly connected to the closing portion 209 (the rear wall 104b). The second surfaces 210b, 212b extend also without interruption between them and face the inner volume 103.

More particularly, the first hooking portion 212 exhibits at least one undercut 216 stably engaged with the second hooking portion 213 disposed in the inner volume 103. The undercut 216 is distinct and distanced from the free edge 206. As illustrated in Figure 16, the undercut 216 comprises at least one hook 220 having a seat 220a provided with a concavity. Preferably, the first hooking portion 212 comprises two hooks 220 having respective seats 220a, the concavities thereof face away from each other. The undercut 216 is engaged with the second hooking portion 213 (Figure 17). The second hooking portion 213 is engaged, in a non-limiting way, with a lateral wall 104 (the front wall 104a) directly facing the inserting portion 210.

The body of sheet material of the second hooking portion 213 extends between a first and second prevalent development surfaces 213a, 213b (Figure 16). The first surface 213a is directly connected to the front lateral wall 104a of the casing 102 and faces the second surface 210b of the inserting portion 210.

The second hooking portion 213 exhibits in turn at least one undercut 217 which is disposed in the inner volume 103 stably (irreversibly) engaged with the undercut 216 of the first hooking portion 212. As illustrated in Figure 15 for example, the undercut 217 exhibits a gripping edge 217a distinct and distanced from the free edge 206 of the casing 102. The undercut 217 exhibits at least one hook 218, which defines a seat 219. The seat 219 exhibits a substantially "C" shape. The seat 219 further exhibits a concavity facing a lateral wall 104 (the front wall 104a) inside which the first hooking portion 212 is housed (held). In other words, the first hooking portion 212 is engaged inside the seat 219 and the undercuts 216, 217 are engaged with each other (see Figure 17, for example). The concavity of the seat 219 of the hook 218 of the second hooking portion 213 faces the concavity of the seat 220a of the hook 220.

In the second embodiment of the package, the container 1 is identical to the one described with reference to the first embodiment, and is configured for cooperating with the casing as described with reference to the first embodiment. Also in the second embodiment, the package 100 comprises at least one open device 160 as described in the first embodiment, and configured for cooperating with the casing and container as described in the first embodiment of the package 100.

1 .3 Third embodiment of the package 100

In a third embodiment of the package 100, the same comprises a casing 102 made of a sheet material, particularly of a paper sheet material, as hereinbefore described with reference to the second embodiment (the casing 102 with the occluding system 207). In the third embodiment, the container 1 is different from the ones described with reference to the first and second embodiments of the package.

Particularly, in the third embodiment, the container 1 defines an inner volume 3 configured for housing at least one product. The container 1 comprises a predetermined number of lateral walls 4 defining at least one passage opening 5 delimited by a free edge 6: the passage opening 5 is configured for enabling the inner volume 3 to communicate with the outer environment. The attached figures illustrate, in a non-limiting way, a configuration of the container 1 exhibiting two passage openings opposite to each other so that this latter can substantially define a conduit or tube laterally delimited by said walls 4 and open at the longitudinal ends. However, it is not excluded the possibility of making, for example, a container 1 exhibiting a single passage opening.

The attached figures illustrate a preferred but non-limiting configuration of the container 1 which exhibits a rectangular prismatic shape (the flat lateral walls 4 have a rectangular shape). Actually, the container 1 exhibits a front wall 4a and a rear wall 4b facing and parallel to each other: the front wall and rear wall are connected to each other by a first and second lateral walls 4c, 4d also facing and parallel to each other. The front wall 4a is distanced from the rear wall 4b; the first and second lateral walls 4c, 4d are also distanced from each other. The container 1 exhibits, along a cross-section transversal to the lateral walls, a parallelogram shape, particularly a square or rectangular shape. However, it is not excluded the possibility of making a container having a different shape, for example a square, trapezoidal shape. Advantageously, the container is at least partially countershaped to the container 102. However, it is not excluded the possibility of making a container 1 having a different shape, for example a square, trapezoidal or cylindrical shape. From the dimensional point of view, the container can define an inner volume 3 substantially larger than 20,000 mm ³ , particularly comprised between 40,000 and 200,000 mm ³ . However, the container 1 , object of the present invention, can be used for packaging medium-sized products; in such condition, the container can exhibit an inner volume 3 larger than 500,000 mm ³ , particularly comprised between 800,000 and 1 ,400,000 mm ³ . However, it is not excluded the possibility of using the container 1 , object of the present invention, for packaging large-sized products; in such condition, the container exhibits an inner volume 3 larger than the above given volumes, for example greater than 10,000 cm ³ .

As it is visible in Figures 24 and 25, for example, the container 1 can comprise, at the free edge 6, a recess 27; as it is visible in the attached figure, the recess 27 contacts the free edge 6 for defining on this latter a type of depression. Advantageously, the recess 27 is defined on the lateral wall 4 (particularly on the front lateral wall 4a) adapted to directly abut against a closing system 7 of the container 1 , which will be better described in the following. The recess 27 exhibits an open perimetral outline which exhibits a substantially "C" or "V" of "U" shape, the concavity thereof facing away from the inner volume.

As it is visible in the attached figures, the container 1 further comprises at least one closing system 7, also made of sheet material, engaged at the free edge 6 and movable, particularly rotatively movably, with respect to the lateral walls 4. Particularly, the closing system 7 is configured for defining at least one closed condition in which the system 7 itself prevents the communication between the inner volume 3 and outer environment; the closing system 7 is further configured for defining at least one open condition in which the system 7 enables the communication between the inner volume 3 and outer environment. De facto, the system 7 is substantially a cover adapted to cooperate with the lateral walls for managing the access to the inner volume 3. Advantageously, the container 1 comprises a closing system 7 for each passage opening 5.

The attached figures illustrate, in a non-limiting way, a configuration of the container 1 exhibiting two passage openings 5; in such condition, the container 1 exhibits two closing systems 7 engaged with the respective free edges 6: the systems 7 are disposed oppositely to each other with respect to the lateral walls 4. The closing system 7 is advantageously, but in a non-limiting way, joined in a single piece to the rear lateral wall 4b, particularly to the free edge 6, and is rotatively movable about this latter, between at least the closed and open conditions.

More particularly, the closing system 7 comprises at least one tab 8 exhibiting a closing portion 9 directly engaged and joined in a single piece to the free edge 6 (particularly to the portion of the free edge of the rear lateral wall 4b): the closing portion 9 is the component of the tab 8 configured for preventing the passage through the opening 5 in the closed condition of the system 7 itself. As it is visible in the attached figures, the closing portion 9 substantially comprises a flat body of sheet material countershaped to the free edge 6 of the opening 5. The attached figures schematically illustrate a preferred configuration of the closing portion 9 exhibiting a rectangular shape completely countershaped to the free edge 6. Moreover, the tab 8 exhibits at least one inserting portion 10 configured for being inserted, in the closed condition of the system 7, inside the volume 3. The inserting portion 10 is joined in a single piece to the closing portion 9: the inserting portion 10 is substantially an extension of the closing portion 9 adapted to be inserted, in the closed condition of the system 7, inside the inner volume 3 of the container 1 . As it is visible in the attached figures, also the inserting portion 10 substantially comprises a flat body of sheet material having, in a non-limiting way, a rectangular shape. As it is visible for example in the cross-section view of Figure 26, the inserting portion 10 extends between a first and second prevalent development surfaces 10a, 10b respectively facing the outside (directly facing a lateral wall 4 of the container 1 ) and towards the inner volume 3. In the closed condition of the system 7, at least one portion of the first development surface 10a of the engagement portion 10 faces, particularly contacts, directly part of a lateral wall 4 (particularly the lateral wall 4a): the surface 10a extends at least partially parallel to the wall 4a opposite to the wall directly connected to the closing portion 9.

The closing portion 9 and inserting portion 10 exhibit a reciprocal connecting edge opposite to the free edge 6 with respect to the closing portion 9 itself: the inserting portion 10 is rotatively movable with respect to the closing portion 9 about said reciprocal connecting edge. The inserting portion 10, in the closed condition of the system 7, is configured for defining, along a cross-section transversal to and cooperatively with the closing portion 9, a substantially "L" shape: in such condition, the inserting portion 10 substantially extends parallel to a lateral wall 4a.

As it is visible in Figures 9, 24 and 25 for example, the closing system 7 further comprises at least one abutment portion 1 1 engaged with the free edge 6 adjacent the tab 8: the abutment portion 1 1 , in the closed condition, is configured for being interposed between the inner volume 3 and tab 8 in order to cooperate with this latter for stably holding it in said closed condition. The abutment portion 1 1 substantially comprises a flat tab of sheet material joined in a single piece to the free edge 6 adjacent the closing portion 9. The abutment portion 1 1 exhibits, in a non-limiting way, a rectangular or trapezoidal shape. Also, the abutment portion 1 1 is configured for rotating about the free edge 6 for facing, at least in the closed condition of the container 1 , the inner volume. More particularly, the abutment portion 1 1 is constrained to the free edge 6 in order to engage, in the closed condition of the container 1 , at least part of the engagement portion 10 and/or of the closing portion 9 for stably holding the tab 8 in said condition. Advantageously, the container 1 comprises two abutment portions 1 1 opposite to each other with respect to the tab 8: this latter is interposed between the two abutment portions 1 1 . In such configuration (illustrated in Figure 25 for example), the two portions 1 1 symmetrically operate on the tab 8 for stably holding it in the closed condition.

As hereinbefore described, the container comprises a recess 27; the recess 27 is disposed on the lateral wall 4 (particularly on the front lateral wall 4a) configured for directly facing the engagement portion 10, particularly the first surface 10a of said portion 10. Therefore, the recess 27 is disposed in proximity of the first surface 10a and is configured for enabling to show this latter under determined operative conditions of the container 1 which will be better described in the following.

As it is visible in the attached figures, the closing system 7 can comprise, in a non-limiting way, a through opening 26 configured for being disposed, in the closed condition of the system itself, at the free edge 6, particularly at the recess 27. De facto, the through opening 26, in the closed condition of the closing system 7, is disposed at the recess 27 (Figure 26): particularly, in such condition, the opening 26 and recess 27 facing and at least partially countershaped to each other.

As it is visible in the attached figures, the through opening 26 defines a closed perimetral outline, particularly exhibiting at least one selected in the group among the following shapes: rectangular, square, circular, elliptical, semicircular, triangular shape. The through opening 26 is defined on the closing portion 9 and/or on the engagement portion 10 of the tab 8. In a preferred but non-limiting embodiment of the invention, the through opening 26 is defined, without interruption, at least partially on the closing portion 9 and at least partially on the engagement portion 10 of the tab 8: the opening 26 is substantially defined on the folding line of the portions 9 and 10 of the tab 8 (Figure 24).

As it is visible in Figures 9, 24 and 25 for example, the container 1 further comprises at least one safety device 12 made of paper sheet material, which exhibits at least one first hooking portion 13 supported by the tab 8 and/or by the abutment portion 1 1 , and at least one second hooking portion 14 engaged with the front wall 4a. The first and second hooking portions 13, 14 are configured for stably engaging each other during one first closed condition of the closing system 7, in other words during a first absolute closure of the system 7 wherein the engagement portion 10 is introduced for the first time into the inner volume 3. As it is visible in the attached figures, the second hooking portion 14 is disposed in the inner volume and substantially lies in a plane parallel to the front lateral wall 4a: in the closed condition of the system 7, the first hooking portion 13 is configured for being inserted at least partially into the inner volume 3 for stably engaging the second hooking portion 14. The first and/or second hooking portions 13, 14 comprise at least one removable portion 15 configured for being separated from the safety device 12 following a first open condition of the closing system 7, after said first closed condition, for evidencing a tampering of the container 1 .

The attached figures illustrate, in a non-limiting way, a configuration of the container 1 in which the first hooking portion 13 is engaged with, particularly directly supported by, the tab 8 of the closing system 7. Advantageously, the first hooking portion 13 is only supported, although in a non-limiting way, by the engagement portion 10 of the tab 8: the two portions 10 and 13 are advantageously joined in a single piece in order to form a single body. De facto, the first hooking portion 13 comprises a flat sheet body emerging, particularly without interruption, from the engagement portion 10 oppositely to the closing portion 9: therefore, the engagement portion 10 is interposed between the closing portion 9 and the first hooking portion 13. The first hooking portion 13, in the closed condition of the system 7 and when inserting the engagement portion 10 into the volume 3, is configured for being also inserted into the inner volume 3.

The body of sheet material of the first hooking portion 13 extends between a first and a second prevalent development surfaces 13a, 13b (Figure 26) respectively facing the same direction of the first and second surfaces 10a, 10b of the engagement portion 10: the first surfaces 10a, 13b are reciprocally without interruption and directly face the front lateral wall 4a opposite to the rear lateral wall 4b directly connected (directly joined in a single piece) to the system 7. The second surfaces 10b, 13b are also reciprocally without interruption and face the inner volume 3. More particularly, the first hooking portion 13 comprises at least one undercut portion 20 delimited by a gripping edge 21 : the undercut portion 20, in the first closed condition of the container 1 , is configured for engaging the second hooking portion 14 disposed in the inner volume. As it is visible in Figure 27, for example, the undercut 20 comprises at least one hook 22 defining a seat, the concavity thereof faces, at least during the first closed condition of the device 12, at least one of the lateral walls 4. The seat of the undercut portion 20 defines a substantially "C" shape: the respective gripping edge 21 delimits a portion of said seat which, in the first closed condition of the system 7, faces the free edge 6.

Figure 24 represents a preferred but non-limiting configuration of the first hooking portion 13 which substantially comprises two hooks 22 opposite to each other with respect to the first portion 13 itself. In such condition, the first portion 13 therefore comprises two respective undercut portions 20 which, at least in the first closed condition of the container 1 , are configured for both engaging the second hooking portion 14. The two undercut portions 20 comprise respective seats, the concavities thereof face away from each other; the concavity of the seat faces respective abutment portions 1 1 . The presence of the two undercuts 20 substantially defines a double symmetric gripping portion on the second hooking portion 14 which makes more effective and stable the coupling between said first and second hooking portions 13, 14.

As hereinbefore described, the second hooking portion 14 of the device 12 is directly engaged into the inner volume 3. Particularly, the second hooking portion 14 is directly connected to at least one lateral wall 4 (particularly to the front lateral wall 4a) and develops parallel to this latter: the hooking portion 14 is configured for directly facing the engagement portion 10 at least during the closed condition of the system 7. De facto, the hooking portion 14 develops parallel to the lateral wall 4 opposite to the wall directly connected (joined in a single piece) to the closing system 7. As it is visible in Figure 26 for example, the second hooking portion 14 is joined in a single piece to the front wall 4a.

The second portion 14 substantially defines a sheet engaged, particularly joined in a single piece to, inside one or more lateral walls 4. The sheet material body of the second hooking portion 14 extends between a first and second prevalent development surfaces 14a, 14b (Figure 26) respectively facing the outside and inside of the volume 3: the first surface 14a of the portion 14, at least in the closed condition of the system 7, is parallel to and faces as the first surfaces 10a, 13a (the first surfaces 10a, 13a, 14a directly faces the lateral wall 4a opposite to the lateral wall 4b directly connected to the system 7).

In the configuration illustrated in the attached figures, the second hooking portion 14 comprises, in a non-limiting way, the removable portion 15 of sheet material which extends between a first and a second surfaces 15a, 15b (Figure 26) respectively facing the lateral wall 4a and lateral surface 4b: the surfaces 15a, 15b of the removable portion 15 are substantially extensions of the surfaces 14a, 14b of the second hooking portion 14. The removable portion 15 comprises at least one undercut portion 16 which is configured for engaging, in the first closed condition of the safety device 12, the respective undercut portion 20 of the first hooking portion 13.

The undercut portion 16 of the removable portion 15 is delimited by a gripping edge 17 which, in the first closed condition of the container 1 itself, is distinct and distanced from the free edge 6: the undercut portion 16 is inside the volume and distanced from the passage opening so that the removable portion 15 can engage, in the first closed condition, the respective undercut 20 of the first hooking portion 13. As it is visible in Figure 24 for example, the undercut portion 16 of the removable portion 15 comprises at least one hook 18 defining a seat exhibiting a substantially "C" shape: the gripping edge 17 delimits the portion of the seat facing away from the free edge 6. More particularly, it is observed that the gripping edge 17 of the removable portion 15, in the first closed condition of the container 1 itself, is interposed between the free edge 6 and the respective gripping edge 21 of the first hooking portion 13.

As hereinbefore described, the first and second hooking portions 13, 14 of the safety device 12 are configured for defining a first closed condition substantially defined by the first engagement/coupling of said portions. Before the first closed condition, the first hooking portion 13 is disposed outside the inner volume 3, while the second hooking portion 14 lies into the volume (this condition is illustrated in Figure 24). Then, the closing system 7 is guided for the first time into the volume 3 as illustrated in Figures 25 and 26 for example: during such step, the system 12 is configured for defining the closed condition of the container 1 and at the same time the first and second hooking portions 13, 14 engage each other for the first time. De facto, during the first closed condition of the container 1 , the hook 18 of the removable portion 15 engages the hook 22 of the first portion 13: the first closed condition is illustrated in Figure 26. Still more particularly, during the first closed condition, the sheet material body of the first hooking portion 13 is configured for sliding, initially behind the removable portion (the removable portion 15 is interposed between the first hooking portion 13 and a lateral wall 4), then is configured for passing through the seat 19 and for being interposed between the lateral wall 4 and second hooking portion 14. In the closed condition, the hook 18 of the removable portion 15 abuts and is stably engaged with the hook 22 of the first portion 13: in such condition, the first portion 13 is completely inserted inside the seat 17 of the removable portion 15 and the respective undercuts 16 and 20 define a stable engagement condition between the portions 13 and 14.

It is useful to observe, for example from Figure 25, that the recess 27 is advantageously disposed at the removable portion 15 of the safety device 12 and at the engagement portion 10 of the tab 8. The recess 27 is configured for enabling to show the removable portion 15, particularly of the first surface 15a, before the first open condition of the container 1 (during the first closed condition of the container 1 ); the recess 27 is further configured for enabling to show the engagement portion 10, particularly the first surface 10a, after the first open condition of the container 1 , for evidencing a tampering of the container 1 .

The stable engagement between the removable portion 15 and first hooking portion 13 opposes the opening of the container 1 ; the user when opens the container for the first time, notices a substantial resistance from the same which is a proof that this latter has never been opened. The safety device 12, during the first open condition, is configured for enabling to separate the first removable portion 15 from the second hooking portion 14. The first open condition is illustrated in Figure 27 for example: during the first open condition of the system 7, the first hooking portion 13 grips the removable portion 15 (the grip is between the hooks 18 and 22) and tears it from the second portion 14.

After the first open condition, the device 12 is capable of evidencing a tampering because the system 7 is easier to open: the user does not detect, during the opening, any resistance on the engagement portion 10 (see Figure 28 which clearly shows the absence of the removable portion 15). Moreover, after the first open condition, the recess 27 enables to show the engagement portion 10 in place of the removable portion 15 (as an alternative enables to show the inner volume 3): in such condition, the user can easily detect the tampering of the container 1 without opening the same. Advantageously, it is possible to differentiate the surfaces 15a and 10a respectively of the removable portion 15 and engagement portion 10 in this way said surfaces can be better identified and the tampering is in this way emphasized. For example, it is possible to provide two different colors for the surfaces 15a and 10a: in this way, the user can detect a tampering of the container 1 only by recognizing the color of the engagement portion 10 rather than the one of the removable portion 15.

It is observed that the above described solution is a preferred even though non-limiting configuration of the container 1 . De facto, the removable portion 15 could form, in an undifferentiated way, at least part of the first and/or of the second hooking portions 13, 14. For example, the removable portion 15 could define the respective undercut 20 and therefore the hook 22 of the first hooking portion 13: in this case, when opening for the first time the container, the removable portion 15 will be configured for being separated from the first portion 13. As hereinbefore described, it is not excluded the possibility of defining at least one removable portion 15 of the first hooking portion 13 and at least one removable portion of the second hooking portion 14.

As illustrated in Figures from 24 to 27, the removable portion 15 can comprise at least one tactilely perceptible projection 25 emerging from the inner volume 3: the removable portion 15, with the projection 25, is configured for separating from the safety device 12 following a first open condition of the closing system 7 after the first closed condition, for evidencing a tampering of the container 1 .

More particularly, the projection 25 of the removable portion 15, in the first closed condition of the closing system 7 and before the first open condition of the container 1 , lies on a plane parallel to the engagement portion 10 and projects from the free edge 6, particularly transversally to the closing portion 9. Still more particularly, the projection 25, in the first closed condition of the closing system 7 and before the first closed condition of the container 1 , is configured for being disposed at the recess 27 and for emerging besides this latter and/or besides the free edge 6. De facto, the projection 25, in the first closed condition of the closing system 7 and before the first open condition of the container 1 , is configured for remaining substantially flush with the closing portion 9 of the tab 8 or is configured for emerging transversally from said closing portion 9; anyway, the projection 25, in both the configurations, is adapted to be tactilely perceptible so that the same can be distinguishable from the closing portion 9, free edge 6 and recess 27.

From the geometrical point of view, the projection 25 exhibits, according to a front view normal to the lying plane of the projection 25 itself, a shape selected in the group comprising: a triangular, square, rectangular, trapezoidal, semicircular, elliptical shape. In a preferred but non-limiting embodiment of the container 1 , the projection 25 exhibits, according to a front view normal to the lying plane of the projection 25 itself, a tapered shape, particularly a triangular one, extending from the free edge 6: the tapered shape of the projection 25 is configured for making easier to tactilely perceive the same during the first closed condition of the closing system 7 and before the first open condition of the container 1 . From the quantitative point of view, the projection 25 extends besides the free edge 6 by more than 1 mm, particularly from 1 to 10 mm, still more particularly from 1 to 7 mm. The tapered shape and height of the projection with respect to at least the free edge 6 of the container 1 , enable to quickly and easily tactilely perceive the projection itself for example by sliding a finger on the closing portion 9 of the tab 8.

The projection 25 supported by the removable portion 15, in the first closed condition of the device 7 and before the first open condition of the container 1 , is distanced from and is disposed opposite to the gripping edge 17 with respect to the removable portion 15; particularly, the projection 25 emerges oppositely to the gripping edge with respect to the removable portion 15 and as hereinbefore described, emerges from the free edge 6. De facto, the second portion 14, during the step of closing the device 7 for the first time and before the step of opening the container 1 for the first time, remains completely inside the volume 3 with the removable portion 15: only the projection 25 of the removable portion 15 emerges at least partially from the volume 3 and particularly besides the free edge 6.

When the removable portion 15 is between the lateral wall 4 of the container 1 and the engagement portion 10 of the tab 8, the projection 25, in the first closed condition of the device 7 and before the first open condition of the container 1 , emerges from the free edge 6 between the tab 8 and the lateral wall 4 directly facing the engagement portion 10. On the contrary, when the removable portion 15 is behind the engagement portion 10, the projection 25 is configured for being disposed inside the through opening 26 of the tab 8; preferably, in such condition, the projection 25 crosses at least partially the passage opening 26 for emerging from the free edge 6 and possibly also from the closing portion 9 of the tab 8 (Figure 26).

As hereinbefore described, the container 1 comprises a recess 27 - preferably supported by the lateral wall 4 parallel to the second hooking portion 14 of the safety device 12 and directly faces the engagement portion 10 - adapted to substantially define a depression of the free edge 6; the recess 27 enables to help the projection 25 to emerge from the free edge 6 following the first closed condition and before the first open condition. De facto, the recess 27 is adapted to enable both to show and tactilely perceive the projection 25.

Following the first opening of the container 1 , the removable portion 15 separates from the container (more generally from the container 1 ) and also the projection 25 does the same so that is no more tactilely perceptible. The absence of the projection 25 can immediately give a proof of a performed tampering of the container also without a visual indication.

Figures 26 and 28 illustrate a further embodiment of the safety device 12 which comprises a control portion 28 of sheet material directly supported by the front lateral wall 4a; the control portion 28 is configured for being disposed, following the first closed condition of the system 7 and before the first open condition of the container 1 , behind the engagement portion 10 so that the same is interposed between said control portion 28 and lateral wall 4a directly abutting against the engagement portion 10.

In such condition, the control portion 28 is completely contained in the inner volume 3 and is directly covered by the removable portion 15. Particularly, the control portion 28 is configured for being disposed immediately behind the projection 25 and immediately behind the portion of the projection emerging from the free edge 6. De facto, the top of the control portion 28 is configured for remaining inside the volume 3 at the free edge 6.

The control portion 28 is configured for being disposed, after the first open condition of the container 1 , behind the engagement portion 10 so that the same is interposed between said control portion 28 and the lateral wall 4a abutting against the engagement portion 10; in such condition, the control portion 28 is completely contained in the inner volume 3 and faces the through opening 26 of the closing system 7.

In the embodiment illustrated in the attached figures, the control portion 28 is supported, in a non-limiting way, directly by the front lateral wall 4a, and comprises a sheet lying parallel to the second hooking portion 14; particularly, the control portion 28 in a non-limiting way, is joined in a single piece and parallel to the second hooking portion 14 of the safety device 12.

As it is visible in Figures from 1 to 9, for example, the container 1 comprises at least one auxiliary through opening 93 defined on a lateral wall 4, particularly on the rear lateral wall 4b, which is delimited by an edge 94 defining the stop element 90 adapted to cooperate, as hereinbefore described with reference to the first embodiment, with the engagement portion 107 of the casing (see the schematic views in Figures 2, 4, 6 and 7).

The auxiliary through opening 93 is disposed on a lateral wall 4 opposite to the lateral wall 4 of the container 1 supporting the second hooking portion 14 of the safety device 12 (Figure 9). Particularly, the second hooking portion 14 of the safety device 12 is directly supported by the front lateral wall 4a of the container, while the through auxiliary opening 93 is defined on the rear lateral wall 4b of the container 1 itself.

The through auxiliary opening 93 extends along a prevalent development direction substantially parallel to the longitudinal development direction of the container 1 ; the auxiliary through opening 93 exhibiting a length - measured normal to the longitudinal development direction of the container - equal to or greater than a width of the engagement portion 107 of the casing 102: said width being measured normal to the longitudinal development direction of the casing 102.

As illustrated in Figure 8, for example, the container 1 can be housed into the inner volume 103 of the casing 102 so that the passage opening 5 of the container - at least in the first operative position - faces the first or second lateral wall 104c, 104d of the casing 102; if the container 1 exhibits two passage openings, one faces the lateral wall 104c and the other faces the lateral wall 104d of the casing 102.

Advantageously, the container 1 can comprise an auxiliary seat 96 defined on the lateral wall 4 itself (the rear lateral wall 4b) on which the abutment element 90 is defined; the auxiliary seat 96 being delimited by an edge 97 which defines an auxiliary stop element 95 also configured for cooperating with the engagement portion 107 of the casing 102. More particularly, the auxiliary stop portion 95 - in the first operative portion of the package 100 - is distanced from the opening 105 so that the stop element 90 is interposed between said passage opening 105 and the auxiliary stop portion 95 (see Figure 4, for example).

The auxiliary stop portion 95 is configured for abutting against the engagement portion of the casing 102 for preventing the container 1 from being completely extracted from the casing 102. De facto, when somebody tries to further extract the container 1 from the casing 102 - starting from the second operative position of the package - the engagement portion 107 is configured for being inserted in the seat 96 and for abutting against the edge 97 (Figure 7) so that the container 1 is prevented from being completely extracted from the casing 102.

In the third embodiment, the package 100 comprises an open device 160 as hereinbefore described with reference to the first embodiment of the package 100.

1 .4 Fourth embodiment of the package 100

In a fourth embodiment of the package 100, the same can comprise a container 1 as described with reference to the first or second or third embodiment of the package 100 as hereinbefore described. Such container 1 is configured for cooperating with the casing as described with reference to the first embodiment and as illustrated in Figures 2, 4, 6 and 7.

In the fourth embodiment, the casing 102 differs from those described with reference to the first, second and third embodiments of the package. Particularly, in such fourth embodiment, the casing 102 comprises a predetermined number of lateral walls 104 defining at least one passage opening 105 delimited by a free edge 106: the passage opening 105 is configured for putting in communication the inner volume 103 with the outer environment. The attached figures illustrate, in a non-limiting way, a configuration of the casing 102 exhibiting two passage openings opposite to each other so that this latter can substantially define a conduit or tube laterally delimited by said walls 104 and open at the longitudinal ends. Still more particularly, the casing 102 extends between a first and second longitudinal end portions 102a, 102b along a longitudinal development direction of the casing itself; the lateral walls 104 therefore define:

- a first passage opening 105 delimited by a free edge 106 and disposed at the first longitudinal end portion 102a, - a second passage opening 205 delimited by a respective free edge 206 and located at the second longitudinal end portion 2b.

The attached figures illustrate a preferred but non-limiting configuration of the casing 102 which exhibits a rectangular prismatic shape (the flat lateral walls 104 having a rectangular shape). The casing 102 actually exhibits a front wall 104a and a rear wall 104b which face and are parallel to each other: the front wall and rear wall are connected to each other by a first and second lateral walls 104c, 104d also facing and parallel to each other. The front wall 104a is distanced from the rear wall 104b; the first and second lateral walls 104c, 104d are also distanced from each other. The casing 102 exhibits, according to a cross-section transversal to the lateral walls, a parallelogram shape, particularly a square or rectangular shape; the free edge 106 defines a parallelogram shape, particularly a square or rectangular shape. However, it is not excluded the possibility of making a casing 102 having a different shape, for example a square, trapezoidal shape.

In the embodiment of the package, the casing 102 comprises an engagement portion 107 at each passage opening; the engagement portion 107 emerges, from at least one lateral wall 104b, inside the inner volume 103 for defining a projection (see Figure 14, for example). In the embodiment illustrated in Figure 29, the casing comprises two engagement portions 107 respectively disposed at the first and second passage openings 105, 205.

The engagement portion 107 is directly constrained, particularly joined in a single piece, to the free edge 106, 206 of the respective passage opening: the engagement portion 107 emerges from the free edge according to a direction entering the inner volume 103. Still more particularly, the engagement portion 107 is constrained to the front lateral wall 104a of the casing 102.

Each engagement portion 107 comprises at least one tab 107a of sheet material, particularly of paper sheet material, joined in a single piece to the front wall 104a. At least part of the tab 107a extends along a rectilinear development direction sloped with respect to an extension direction of the front wall 104a to which the tab 107a itself is joined in a single piece. The tab defines - with the front wall to which the tab itself is joined in a single piece - an angle equal to or greater than 1 °, particularly comprised between 1 ° and 15°, still more particularly comprised between 1 ° and 5°; said angle being defined in the inner volume and being subtended between the tab 107a and the front and/or rear lateral walls to which the tab itself is joined in a single piece.

From the dimensional point of view, the casing 102 defines an inner volume 103 substantially greater than 20,000 mm ³ , particularly comprised between 40,000 and 200,000 mm ³ . However, the casing 102 object of the present invention, can be used for packaging medium-sized products; in such condition, the package can exhibit an inner volume greater than 500,000 mm ³ , particularly comprised between 800,000 and 1 ,400,000 mm ³ . However, it is not excluded the possibility of using the container 1 for packaging large-sized products; in such condition, the casing 102 can exhibit an inner volume 103 greater than the above given volumes, for example greater than 10,000 cm ³ and although in a non- limiting way.

The casing comprises, at each free edge, a recess 327; as it is visible in the attached figures, the recess 327 contacts the free edge for defining, on this latter, a kind of depression. Advantageously, the recess 327 is defined on the front lateral wall 104a adapted to directly abut against a closing system 307 of the casing 102 which will be better described in the following. The recess 327 exhibits an open perimetral outline which exhibits a substantially "C" or "V" or "U" shape, the concavity thereof faces away from the inner volume 103.

As it is visible in the attached figures, the casing 102 further comprises at least one closing system 307, also made of sheet material, engaged at each free edge and movable, particularly rotatively movable, with respect to the lateral walls 104. Specifically, the closing system 307 is configured for defining at least one closed condition in which the system 307 itself prevents the communication between the inner volume 103 and outer environment; the closing system 307 is further configured for defining at least one open condition in which the system 307 itself enables the communication between the inner volume 103 and outer environment. De facto, the system 307 is substantially a cover adapted to cooperate with the lateral walls for managing the access to the inner volume 103e and therefore to the container 1 disposed inside the casing 102. Advantageously, the casing 102 comprises a closing system 307 for each passage opening as illustrated in Figure 29, for example.

The attached figures illustrate, in a non-limiting way, a configuration of the casing 102 exhibiting two passage openings; in such condition, the casing 102 exhibits two closing systems 307 engaged with the respective free edges: the systems 307 are disposed oppositely to each other with respect to the lateral walls 104. The closing system 307 is advantageously, although in a non-limiting way, joined in a single piece to the rear lateral wall 104b, and is rotatively movable about this latter, between at least the closed and open conditions.

More particularly, the closing system 307 comprises at least one tab 308 which exhibits a closing portion 309 directly engaged and joined in a single piece to the free edge (particularly to the portion of the free edge of the rear lateral wall 104b): the closing portion 309 is the component of the tab 308 configured for preventing the passage through the opening in the closed condition of the system 307 itself. As it is visible in the attached figures, the closing portion 309 substantially comprises a flat body of sheet material countershaped to the free edge of the opening. The attached figures schematically illustrate a preferred configuration of the closing portion 309 exhibiting a rectangular shape completely countershaped to the free edge. Moreover, the tab 308 exhibits at least one inserting portion 310 configured for being inserted, in the closed condition of the system 307, inside the volume 103. The inserting portion 310 is joined in a single piece to the closing portion 309: the inserting portion 310 is substantially an extension of the closing portion 309 adapted to be inserted, in the closed condition of the system 307, into the inner volume 103. As it is visible in the attached figures, also the inserting portion 310 substantially comprises a flat body of sheet material having, in a non-limiting way, a rectangular shape. As it is visible for example in the cross-section view of Figure 35, the inserting portion 310 extends between a first and second prevalent development surfaces 310a, 310b respectively facing the outside (directly facing the front lateral wall 104a) and facing the inner volume 103. In the closed condition of the system 307, at least one portion of the first development surface 310a of the inserting portion 310 faces, particularly directly contacts, part of a lateral wall 104 (particularly the lateral wall 104a): the surface 310a extends at least partially parallel to the wall 104a oppositely to the wall directly connected to the closing portion 309.

The closing portion 309 and inserting portion 310 exhibit a reciprocal connecting edge opposite to the free edge with respect to the closing portion 309 itself: the inserting portion 310 is rotatively movable with respect to the closing portion 309 about said reciprocal connecting edge. The inserting portion 310, in the closed condition of the system 307, is configured for defining, according to a cross-section and cooperatively with the closing portion 309, a substantially "L" shape: in such condition, the inserting portion 310 substantially extends parallel to a lateral wall 104a.

As it is visible in Figure 33 for example, the closing system 307 further comprises at least one abutment portion 31 1 engaged with the free edge adjacent the tab 308: the abutment portion 31 1 , in the closed condition, is configured for being interposed between the inner volume 103 and tab 308 so that it cooperates with this latter for stably holding it in said closed condition. The abutment portion 31 1 substantially comprises a flat tab of sheet material joined in a single piece to the free edge adjacent the closing portion 309. The abutment portion 31 1 exhibits, in a non-limiting way, a rectangular or trapezoidal shape. Also, the abutment portion 31 1 is configured for rotating about the free edge for facing, at least in the closed condition of the casing 102, the inner volume 103. More particularly, the abutment portion 31 1 is constrained to the free edge in order to engage, in the closed condition of the casing 102, at least part of the inserting portion 310 and/or of the closing portion 309 for stably holding the tab 308 in said condition. Advantageously, the casing 102 comprises two abutment portions 31 1 opposite to each other with respect to the tab 308: this latter is interposed between the two abutment portions 31 1 . In such configuration, the two portions 31 1 symmetrically operate on the tab 8 for stably holding it in the closed condition.

As hereinbefore described, the container comprises a recess 327; the recess 327 is disposed on the lateral wall 104 (particularly on the front lateral wall 104a) configured for directly facing the inserting portion 310, particularly the first surface 310a of said portion 310. Therefore, the recess 327 is disposed in proximity of the first surface 310a and is configured for enabling to show this latter under determined operative conditions of the casing 102 which will be better described in the following.

As it is visible in the attached figures, the closing system 307 can comprise, in a non-limiting way, a through opening 326 configured for being disposed, in the closed condition of the system itself, at the free edge, particularly at the recess 327. De facto, the through opening 326, in the closed condition of the closing system 37, is disposed at the recess 327 (Figure 35): particularly, in such condition, the opening 326 and recess 327 face and at least are partially countershaped to each other.

As it is visible in the attached figures, the through opening 326 defines a closed perimetral outline, particularly exhibiting at least one selected in the group among the following shapes: rectangular, square, circular, elliptical, semicircular, triangular shape. The through opening 326 is defined on the closing portion 309 and/or on the inserting portion 310 of the tab 308. In a preferred but non-limiting embodiment of the invention, the through opening 326 is defined, without interruption, at least partially on the closing portion 309 and at least partially on the inserting portion 310 of the tab 308: the opening 326 is substantially defined on the folding line of the portions 309 and 310 of the tab 308 (Figure 33).

As it is visible in Figures 33, 34 and 36 for example, the casing 102 further comprises at least one safety device 312, made of paper sheet material, which exhibits at least one first hooking portion 313 supported by the tab 308 and/or by the abutment portion 31 1 , and at least one second hooking portion 314 engaged with the front wall 104a. The first and second hooking portions 313, 314 are configured for stably engaging with each other during one first closed condition of the closing system 307, in other words during a first absolute closure of the system 307 in which the inserting portion 310 is introduced for the first time into the inner volume 103. As it is visible in the attached figures, the second hooking portion 314 is disposed in the inner volume 103 and substantially lies in a plane parallel to the front lateral wall 104a: in the closed condition of the system 307, the first hooking portion 313 is configured for being inserted at least partially into the inner volume 103 for stably engaging the second hooking portion 314. The first and/or second hooking portions 313, 314 comprise at least one removable portion 315 configured for being separated from the safety device 312 following a first open condition of the closing system 307, after said first closed condition, for evidencing a tampering of the casing 102.

The attached figures illustrate, in a non-limiting way, a configuration of the casing 102 wherein the first hooking portion 313 is engaged with, particularly directly supported by, the tab 308 of the closing system 307. Advantageously, the first hooking portion 313 is only supported, although in a non-limiting way, by the inserting portion 310 of the tab 308: the two portions 310 and 313 are advantageously joined in a single piece in order to form a single body. De facto, the first hooking portion 313 comprises a flat sheet body emerging, particularly without interruption, from the engagement portion 130 oppositely to the closing portion 309: therefore, the inserting portion 310 is interposed between the closing portion 309 and the first hooking portion 313. The first hooking portion 313, in the closed condition of the system 307 and therefore when inserting the inserting portion 310 into the volume 103, is configured for being also inserted into the inner volume 103.

The sheet material body of the first hooking portion 313 extends between a first and a second prevalent development surfaces 313a, 313b (Figure 35) respectively facing the same direction of the first and second surfaces 310a, 310b of the inserting portion 310: the first surfaces 310a, 313a are reciprocally without interruption and directly face the front lateral wall 104a opposite to the rear lateral wall 104b directly connected (directly joined in a single piece) to the system 307. The second surfaces 310b, 313b are reciprocally also without interruption and face the inner volume 103.

More particularly, the first hooking portion 313 comprises at least one undercut portion 320 delimited by a gripping edge 321 : the undercut portion 320, in the first closed condition of the casing 102, is configured for engaging the second hooking portion 314 disposed in the inner volume 103. As it is visible in Figure 33, for example, the undercut 320 comprises at least one hook 322 defining a seat, the concavity thereof faces, at least during the first closed condition of the device 312, at least one of the lateral walls 104. The seat of the undercut portion 320 defines a substantially "C" shape: the respective gripping edge 321 delimits a portion of said seat which, in the first closed condition of the system 307, faces the free edge.

Figure 33 represents a preferred but non-limiting configuration of the first hooking portion 313 which substantially comprises two hooks 322 opposite to each other with respect to the first portion 313 itself. In such condition, the first portion 313 therefore comprises two respective undercut portions 320 which, at least in the first closed condition of the casing 102, are configured for both engaging the second hooking portion 314. The two undercut portions 320 comprise respective seats, the concavities thereof face away from each other; the concavity of the seats faces respective abutment portions 31 1 . The presence of the two undercuts 320 substantially defines a double symmetric grip on the second hooking portion 314 which makes more effective and stable the coupling between said first and second hooking portions 313, 314.

As hereinbefore described, the second hooking portion 314 of the device

212 is directly engaged into the inner volume 103. Particularly, the second hooking portion 414 is directly connected to at least one lateral wall 104 (particularly to the front lateral wall 104a) and develops parallel to this latter: the hooking portion 314 is configured for directly facing the inserting portion 310 at least during the closed condition of the system 307. De facto, the hooking portion 314 develops parallel to the lateral wall 104 opposite to the wall directly connected (joined in a single piece) to the closing system 307. As it is visible in Figure 34 for example, the second hooking portion 314 is joined in a single piece to the front wall 104a.

The second portion 314 substantially defines a sheet engaged, particularly joined in a single piece, inside one or more lateral walls 104. The sheet material body of the second hooking portion 314 extends between a first and second prevalent development surfaces 314a, 314b (Figure 35) respectively facing the outside and the inside of the volume 103: the first surface 314a of the portion 314, at least in the closed condition of the system 307, is parallel to and faces as the first surfaces 310a, 313a (the first surfaces 310a, 313a, 314a directly facing the lateral wall 104a opposite to the lateral wall 104b directly connected to the system 307). In the configuration illustrated in the attached figures, the second hooking portion 314 comprises, in a non-limiting way, the removable portion 315 of sheet material which extends between a first and a second surfaces 315a, 315b (Figure 35) respectively facing the lateral wall 104a and lateral surface 104b: the surfaces 315a, 315b of the removable portion 315 are substantially extensions of the surfaces 314a, 314b of the second hooking portion 314. The removable portion 315 comprises at least one undercut portion 316 which is configured for engaging, in the first closed condition of the safety device 312, the respective undercut portion 320 of the first hooking portion 313.

The undercut portion 316 of the removable portion 315 is delimited by a gripping edge 317 which, in the first closed condition of the casing 102 itself, is distinct and distanced from the free edge: the undercut portion 316 is inside the volume and distanced from the passage opening so that the removable portion 315 can engage, in the first closed condition, the respective undercut 320 of the first hooking portion 313.

As it is visible in Figure 33 for example, the undercut portion 316 of the removable portion 315 comprises at least one hook 318 defining a seat exhibiting a substantially "C" shape: the gripping edge 317 delimits the portion of the seat facing away from the free edge. More particularly, it is possible to note that the gripping edge 317 of the removable portion 315, in the first closed condition of the casing 102 itself, is interposed between the free edge and the respective gripping edge 321 of the first hooking portion 313.

As hereinbefore described, the first and second hooking portions 313, 314 of the safety device 312 are configured for defining a first closed condition substantially defined by the first engagement/coupling of said portions. Before the first closed condition, the first hooking portion 313 is disposed outside the inner volume 103, while the second hooking portion 314 lies into the volume (this condition is illustrated in Figure 33). Then, the closing system 307 is guided for the first time into the volume 103 as illustrated in Figures 34 and 35 for example: during such step, the system 312 is configured for defining the closed condition of the casing 102 and for the first time there is the engagement between the first and second hooking portions 313, 314. De facto, during the first closed condition of the casing 102, the hook 318 of the removable portion 315 engages the hook 322 of the first portion 313: the first closed condition is illustrated in Figure 35. Still more particularly, during the first closed condition, the sheet material body of the first hooking portion 313 is configured for sliding, initially behind the removable portion (the removable portion 315 is interposed between the first hooking portion 313 and a lateral wall 104), then crosses the seat 319 and is interposed between the lateral wall 104 and second hooking portion 314. In the closed condition, the hook 318 of the removable portion 315 abuts and is stably engaged with the hook 322 of the first portion 313: in such condition, the first portion 313 is completely inserted inside the seat 317 of the removable portion 315 and the respective undercuts 316 and 320 define a stable engagement condition between the portions 313 and 314. It is useful to note, for example from Figure 34, that the recess 327 is advantageously disposed at the removable portion 315 of the safety device 312 and at the inserting portion 310 of the tab 308. The recess 327 is configured for enabling to show the removable portion 315, particularly of the first surface 315a, before the first open condition of the casing 102 (during the first closed condition of the container 1 ); the recess 327 is further configured for enabling to show the inserting portion 310, particularly the first surface 310a, after the first open condition of the casing 102, for evidencing a tampering of the casing 102.

The stable engagement between the removable portion 315 and first hooking portion 313 opposes the opening of the casing 102; the user when opens the container for the first time, detects a substantial resistance when opening the same which is a proof that this latter was not already opened. The safety device 312, during the first open condition, is configured for enabling to separate the removable portion 315 from the second hooking portion 314. The first open condition is illustrated in Figure 36 for example: during the first opening of the system 307, the first hooking portion 313 grips the removable portion 315 (the grip is between the hooks 318 and 322) and tears it from the second portion 314.

Following the first open condition, the device 312 is capable of evidencing a tampering because the system opening 307 is easy to open: the user does not perceive, when opening, a resistance on the inserting portion 310 (see Figure 37 wherein it is evident the absence of the removable portion 315). Moreover, after the first open condition, the recess 327 enables to show the inserting portion 310 instead of the removable portion 315 (as an alternative enables to show the inner volume 103): in such condition, the user can be easily aware of e tampering of the casing 102 without opening the same. Advantageously, it is possible to make different the surfaces 315a and 310a respectively of the removable portion 315 and inserting portion 310 in order to make easier to recognize said surfaces, emphasizing in this way the tampering. For example, it is possible to provide two different colors of the surfaces 315a and 310a: in this way, the user can be aware of the tampering of the casing 102 only by recognizing the color of the inserting portion 310 rather than the one of the removable portion 315.

It is useful to note that the above described solution is a preferred although in a non-limiting configuration of the casing 102. De facto, the removable portion 315 can form part of either the first and/or the second hooking portions 313, 314. For example, the removable portion 315 can define the respective undercut 320 and therefore the hook 322 of the first hooking portion 313: in this way, when opening for the first time the container, the removable portion 315 would be configured for separating from the first portion 313. As hereinbefore described, it is not excluded the possibility of defining at least one removable portion 315 of the first hooking portion 313 and at least one removable portion of the second hooking portion 314.

As illustrated in Figures from 33 to 36, the removable portion 315 can comprise at least one tactilely perceptible projection 325 emerging from the inner volume 103: the removable portion 315, together with the projection 325, is configured for separating from the safety device 312 following a first open condition of the closing system 307 after the first closed condition, for evidencing a tampering of the casing 102.

More particularly, the projection 325 of the removable portion 315, in the first closed condition of the closing system 307 and before the first open condition of the casing 102, lies on a plane parallel to the inserting portion 310 and projects from the free edge, particularly transversally to the closing portion 309. Still more particularly, the projection 325, in the first closed condition of the closing system

307 and before the first open condition of the casing 102, is configured for being disposed at the recess 327 and for emerging besides this latter and/or besides the free edge. De facto, the projection 325, in the first closed condition of the closing system 307 and before the first open condition of the casing 102, is configured for remaining substantially flush with the closing portion 309 of the tab

308 or is configured for emerging transversally from said closing portion 309; anyway, the projection 325, in both the configurations, is adapted to be tactilely perceivable so that the same can be distinguishable from the closing portion 309, of the free edge and from the recess 327.

From the geometrical point of view, the projection 325 exhibits, according to a front view normal to the lying plane of the projection 325 itself, a shape selected in the group comprised among: triangular, square, rectangular, trapezoidal, semicircular, elliptical shape. In a preferred but non-limiting embodiment of the casing 102, the projection 325 exhibits, according to a front view normal to the lying plane of the projection 325 itself, a tapered shape, particularly a triangular one, extending from the free edge: the tapered shape of the projection 325 is configured for making easier to tactilely perceive the same during the first closed condition of the closing system 307 and before the first open condition of the casing 102. From the quantitative point of view, the projection 325 extends besides the free edge by an amount greater than 1 mm, particularly from 1 to 10 mm, still more particularly from 1 to 7 mm. The tapered shaped and height of the projection with respect to at least the free edge, enable to easily and quickly tactilely perceive the projection itself for example by sliding a finger on the closing portion 309 of the tab 308.

The projection 325 supported by the removable portion 315, in the first closed condition of the device 307 and before the first open condition of the casing 102, is distanced from and is disposed oppositely to the gripping edge 317 with respect to the removable portion 315; particularly, the projection 325 emerges oppositely to the gripping edge with respect to the removable portion 315 and, as hereinbefore described, emerges from the free edge. De facto, the second portion 314, in the first closing step of the device 307 and before the first opening step the casing 102, remains completely inside the volume 103 with the removable portion 315: only the projection 325 of the removable portion 315 emerges at least partially from the volume 103 and particularly besides the free edge.

When the removable portion 315 is between the lateral wall 104 and the inserting portion 310 of the tab 308, the projection 325, in the first closed condition of the device 307 and before the first open condition of the casing 102, emerges from the free edge between the tab 308 and the lateral wall 104 directly facing the inserting portion 310. On the contrary, when the removable portion 315 should be located behind the engagement portion 130, the projection 325 is configured for being disposed inside the through opening 326 of the tab 308; preferably, in such condition, the projection 325 crosses at least partially the passage opening 326 for emerging from the free edge and possibly also from the closing portion 309 of the tab 308 (Figure 35).

As hereinbefore described, the casing 102 comprises a recess 327 - preferably supported by the lateral wall 104 parallel to the second hooking portion 314 of the safety device 312 and directly facing the inserting portion 310 - adapted to substantially define a depression of the free edge; the recess 327 enables the projection 325 to easily emerge from the free edge following the first closed condition and before the first open condition. De facto, the recess 327 is adapted to enable both to show and tactilely perceive the projection 325.

Following the first opening condition of the casing 102, the removable portion 315 separates from the casing 102 and also the projection 325 which is no more tactilely perceivable. The absence of the projection 325 can immediately give a proof that the casing 102 was tampered also without a visual indication.

Figures 35 and 37 illustrate a further embodiment of the safety device 312 which comprises a control portion 328 of sheet material directly supported by the front lateral wall 104a; the control portion 328 is configured for being disposed, following the first closed condition of the system 307 and before the first open condition of the casing 102, behind the inserting portion 310 so that the same is interposed between said control portion 328 and lateral wall 104a directly abutting against the inserting portion 310.

In such condition, the control portion 328 is completely contained in the inner volume 103 and is directly covered by the removable portion 315. Particularly, the control portion 328 is configured for being disposed immediately behind the projection 325 and immediately behind the portion of the projection emerging from the free edge. De facto, the top of the control portion 328 is configured for remaining inside the volume 103 at the free edge.

The control portion 328 is configured for being disposed, after the first open condition of the casing 102, behind the inserting portion 310 so that the same is interposed between said control portion 328 and the lateral wall 104a abutting against the inserting portion 310; in such condition, the control portion 328 is completely contained into the inner volume 103 and faces the through opening 326 of the closing system 307.

In the embodiment illustrated in the attached figures, the control portion 328 is supported, in a non-limiting way, directly by the front lateral wall 104a, and comprises a sheet lying parallel to the second hooking portion 314; particularly, the control portion 328, in a non-limiting way, is joined in a single piece and parallel to the second hooking portion 314 of the safety device 312.

In the fourth embodiment, the package 100 comprises an open device 160 as described with reference to the first embodiment of the package.

- at least one fourth sheet 510 exhibiting at least one portion 51 1 joined in a single piece to the second portion 509 of the third sheet 507, the second portion 509 of the third sheet 507 being interposed between the first portion 507 of the third sheet 507 itself and the portion 51 1 of the fourth sheet 510,

- at least one fifth sheet 512 connected to the second end edge of the second portion 504 of the first sheet 501 , the fifth sheet 512 comprising a first portion and second portion 513, 514, the fifth sheet 512 and the third sheet 507 being disposed on the same end edge of the first sheet 501 oppositely to the second sheet 521 , said second portion 514 of the fifth sheet 512 being constrained to the first portion 513 of the fifth sheet 512 itself by at least one weakening line 514a.

The process comprises at least the following steps:

- folding the fifth sheet 512 on the second portion 504 of the first sheet 501 for defining the second hooking portion 314 of the closing system 307,

- after folding the first sheet, folding the third and fourth sheets for defining the closing system 307.

Advantageously, the first semifinished product 500 comprises a second, third, fourth and fifth sheets for each end edge for defining a casing 102 having a tubular form, a first and second through openings being at the longitudinal ends 102a, 102b: for each opening, the casing comprises a closing system 307 and safety system 312 as illustrated in Figures 29, 30.

Moreover, the process comprises a step of providing the container 1 ; such step provides folding a second semifinished product 50 of sheet material, particularly of a paper sheet. The second semifinished product 50 comprises at least one first sheet 51 comprising at least one first and one second portions 52, 54 interconnected by a central connecting portion 53. Moreover, the first sheet 51 comprises at least one first and one second lateral connecting portions 55, 56, the first portion 52 is interposed between the first lateral connecting portion 55 and the central connecting portion 53; the second portion 54 is interposed between the central connecting portion 53 and the second lateral connecting portion 56: each of said portions 52, 53, 54, 55, 56 comprises at least one first and one second longitudinal edges opposite to each other and one first and one second end edges opposite to each other. The first end edges of the portions 52, 53, 54, 55, 56 of the first sheet 51 define a first end edge of said first sheet. The second end edges of the portions 52, 53, 54, 55, 56 of the first sheet 51 define a second end edge of said first sheet. The portions 52, 54, the central connecting portion 53 and said lateral connecting portions 55, 56 are joined along the longitudinal edges and are aligned along a single connecting direction. The first sheet exhibits, on the first portion 52, at least one cut 85a.

The process provides a step of folding the first sheet 51 along the longitudinal edges of the portions of the central sheet itself by joining said lateral connecting portions 55, 56 for defining the container exhibiting at least the opening 5. During such folding step, the first and second lateral connecting portions 55, 56 are constrained, for example by gluing, to each other. The cut 85a is adapted to define on the first sheet 51 , at least one stop element 90.

The first portion 52 can comprise a plurality of cuts 85a for defining a plurality of stop elements 90. The cut 85a can exhibit a closed outline for defining, on the first portion 52, a cavity passing through the sheet. As an alternative, the cavity 85a can exhibit, as illustrated in the attached figures, an open outline defining, on the first portion, a tab 85 connected to the first portion by a creasing 85b, in such condition, following the step of folding the first sheet, the process provides folding the tab 85 for defining said stop element 90.

Moreover, the first sheet 51 comprises at least one through groove 75 (see Figure 20, for example) disposed on the first and/or on the second portions 52, 54 which is configured for defining the recess 27. The groove 75 is made substantially at the first and/or second end edges of said portions 52, 54. Particularly, the through groove 74 is defined on at least one transversal edge of the first or second portion 52, 54 of the first sheet 51 ; in Figure 20, the groove 75 is defined at the transversal edges of the second portion 54. The through groove 75 defines an open outline having a substantially "C" (Figure 20), or "U" or "V" shape.
