Description:
WALL AND PROCESS OF MAKING THE SAME, CHILD-PROOF PACKAGE

DESCRIPTION

FIELD OF THE INVENTION

The object of the present invention is a wall made of sheet material, and a process for making the same, employable for making child-proof packages. The present invention also regards a child-proof package and a process for making the same, as well as a method for closing and opening the package; the package can be employed in the field of packaging for products of various kind, such as: drugs, cosmetics, cleaning products (detergents for linens/sheets and dishes), foods and tobacco-based products (cigars and cigarettes).

BACKGROUND ART

As is known, child-proof packages are available on the market that are employed for preventing young children from coming into contact with products that are potentially harmful for them. A first type of known packages is described in the following patents: US 2005/0173291 A1; EP 2 808 265 A1; US 6,491,211 B1; WO 2005/068304 A2; US 2014/262839 A1; EP 2 810 885 A1 ; US 2012/234701 A1; CN 204642 380 U; WO 2012/112538 A1; WO 2009/038219 A1; US 1,253,489 A. Such packages have a locking system which allows maintaining such packages in a closed condition; the packages can be opened by means of intervention from outside by the user on the locking system: the intervention is allowed due to the presence of a through access defined on a lateral wall of the package. The Applicant has however detected that such known packages have a complex structure and a locking system that can be easily circumvented: such packages are not able to provide a suitable level of safety and prevent children younger than 5 from opening the package.

A second type of package is described in the patent application No. WO 2017/216662 A1. The package comprises a container for housing products recloseable by means of a case; the container and the case comprise respective coupling portions configured for being engaged with each other following a closing of the package in order to allow the locking of the container within the case and consequently preventing the removal of products. The disengagement between the case and the container occurs following the insertion of an opening device in interposition between said coupling portions. Even if the package described in the application No. WO 2017/216662 A1 is improved with respect to the packages of the first type since it is simpler structurally and more effective in terms of safety, the Applicant has also detected that such package can be improved with regard to several aspects.

OBJECT OF THE INVENTION

Object of the present invention is therefore that of substantially resolving at least one of the drawbacks and/or limitations of the preceding solutions.

One objective of the present invention is that of providing a wall made of sheet material that is flexible in use, employable in order to define walls of packages or containers of child-proof type. A further objective of the present invention is that of providing a wall made of sheet material having a structure that is compact and simultaneously extremely strong.

One objective of the present invention is that of providing a package having a highly effective safety system capable of preventing the opening of the package by children but which at the same time can be easily openable by an adult. Another object of the present invention is to provide a package having a simple and compact structure, attainable in a quick and inexpensive manner. Another object of the present invention is to provide a package having a stable structure capable of ensuring the integrity thereof following multiple openings and closings of the same.

These and still other objects, which will be clearer from the following description, are substantially attained by a wall, a package, a process for making the wall and the package as well as a method for closing and opening the package in accordance with that expressed in one or more of the enclosed claims and/or with any one of the further aspects or characteristics described hereinbelow.

DETAILED DESCRIPTION

Wall 60

Reference number 60 overall indicates a wall employable for making packages or containers, for example of child proof type, for containing products of various type.

As is visible from figures 4, 8, 9, 15, 17, 20 and 21, the wall 60 comprises an outer panel 61 made of sheet material extended along a main development plane and having a rectangular form. It is however possible to make an outer panel 61 having a different form, e.g. square, elliptical, semi-circular, triangular or trapezoidal.

As is visible from the enclosed figures, the outer panel 61 comprises at least one through opening 61a which is extended through the entire thickness of the outer panel 61. The through opening 61 a is delimited by a perimeter edge which delimits a passage area of the through opening 61a. In detail, the perimeter edge of the through opening 61a of the outer panel is of closed type and is entirely contained within an outer perimeter edge delimiting the outer panel 61. For example, the ratio between the surface area (extension) of the outer panel 61 and the passage area of the through opening 61a is larger than 1.5, optionally larger than 2, still more optionally comprised between 3 and 20.

In figures 4, 8 and 9, a through opening 61a was illustrated having a substantially "T" shape substantially positioned at a central zone of the outer panel 61. In figure 15, an outer panel 61 is illustrated having two through openings 61 a with closed profile, each of which extended along a trajectory extended essentially as a circular arc. In figure 17, a through opening 61a is illustrated, having circular shape. It is possible however to make a through opening 61a of the outer panel 61 having a different form, e.g. rectangular, square, elliptical or extended along one or more trajectories.

As is visible for example from figures 5, 19 and 21 , the wall 60 also comprises an inner panel 62 made of sheet material which is extended along a main development plane and having a rectangular form. It is however possible to make an inner panel 62 having a different form, e.g. square, elliptical, semicircular, triangular or trapezoidal; in detail, the outer panel 61 and the inner panel 62 have the same shape and optionally the same size. For example, the outer and inner panels can have a surface area, measured along the development plane of the same panel, larger than 8 cm 2 , optionally equal to or larger than 20 cm 2 , still more optionally comprised between 20 and 500 cm 2 ; in detail, the outer and inner panels can have a length equal to or larger than 5 cm, optionally comprised between 8 and 40 cm, and a width equal to or larger than 5 cm, optionally comprised between 8 and 40 cm.

As is visible from the enclosed figures, the outer panel 61 and the inner panel 62 are engaged with each other and are extended parallel to each other: the main development planes of the panels 61 and 62 are parallel to each other.

As is visible for example from figures 5 and 19, the inner panel 62 comprises at least one respective through opening 62a which is extended through the entire thickness of the inner panel 62. The through opening 62a is delimited by a perimeter edge which delimits a passage area of the through opening 62a. In detail, the perimeter edge of the through opening 62a of the inner panel 62 is of closed type and is entirely contained within an outer perimeter edge delimiting the inner panel 62. For example, the ratio between surface area (extension) of the inner panel 62 and the passage area of the through opening 62a is larger than 1.5, optionally larger than 2 still more optionally comprised between 3 and 20.

In figure 5, a through opening 62a is illustrated having a circular shape positioned substantially at a central zone of the inner panel 62. In figure 19, a through opening 62a is instead illustrated, having a rectangular shape. It is however possible to make a through opening 62a of the inner panel 62 having a different form, e.g. square, elliptical or extended along one or more trajectories.

As schematized in figures 6-9, 15, 17 and 20, the through openings 61a, 62a of the outer and inner panels are aligned along a direction orthogonal to the development plane of the outer panel (optionally of the outer panel and of the inner panel since they are parallel to each other). With regard to size, the through openings 61a, 62a of the outer and inner panels can have the same size, i.e. substantially define the same passage area or, as illustrated in the enclosed figures, they can have different shape and size. In detail, the passage area of the through opening 61a of the outer panel 61 is larger than the passage area of the through opening 62a of the inner panel 62. In still more detail, the ratio between the passage area of the through opening 61a of the outer panel 61 and the passage area of the through opening 62a of the inner panel 62 is equal to or larger than 1, optionally comprised between 1.1 and 10. It is however possible to make a through opening 62a of the inner panel 62 having a passage area larger than the passage area of the through opening 61a of the outer panel 61 as is for example illustrated in figure 20.

As is visible from the enclosed figures, the wall also comprises a selector 90, also made of sheet material, engaged in interposition between the outer panel 61 and the inner panel 62, which is extended along a main development plane; in detail, also the selector 90 is extended along a main development plane parallel to the outer and inner panels: the main development plane of the selector is parallel to at least one between the main development plane of the outer panel 61 and the main development plane of the inner panel 62.

As is visible from the enclosed figures, the selector 90 is larger than the through openings 61a, 62a of the outer and inner panels in a manner such that said panel can engage said selector without the same being able to exit outward from one of the through openings of the outer and inner panels. In detail, the selector 90 has an (outer) surface area larger than the passage area of the through openings 61a, 62a of the outer and inner panels; said surface area being measured along the development plane of the selector 90. In still more detail, selector 90 is perimetrically delimited by a closed outer edge which, visible along a direction orthogonal to the development plane of the selector 90, at least partly contains the through opening 61 a of the outer panel 61 and the through opening 62a of the inner panel 62.

As is visible from the enclosed figures, also the selector 90 is provided with at least one through opening 91 which is extended through the entire thickness of the selector 90. The through opening 91 is delimited by a perimeter edge which delimits a passage area of the through opening 91 of the selector. In detail, the perimeter edge of the through opening 91 of the selector is of closed type and is entirely contained within an outer perimeter edge delimiting the selector 90. For example, the ratio between surface area (extension) of the separator 90 and the passage area of the through opening 91 of the same separator is larger than 1.5, optionally comprised between 2 and 10.

As is visible for example in figures 5, 8, 9, 16 and 17, the through opening 91 of the selector 90 can have a circular shape, e.g. substantially equal (at least regarding shape) to the through opening 62a of the inner panel 62. The through opening 91 of the selector can nevertheless have a different shape, e.g. square, elliptical or extended along one or more trajectories. As specified above, the through opening 91 of the selector 90 defines a predetermined passage area which can be substantially identical to the passage area of the through opening 62a of the inner panel 62; It is however possible to make a passage opening 91 of the selector whose passage area is smaller or larger than the passage area of the through opening of the inner panel 62. The through opening 61a of the outer panel 61 instead has a passage area larger than the passage area defined by the through opening 91 of the selector 90; in detail, the ratio between the passage area of the through opening 61a of the outer panel 61 and the passage area defined by the through opening 91 of the selector 90 is larger than 1.1, optionally comprised between 1.2 and 8. The selector 90 is configured for being moved relative to at least between the outer panel and the inner panel at least between:

- a first operative position in which the through opening 91 of the selector 90 is at least partly facing the through openings 61a, 62a of the outer and inner panels 61 , 62 so as to define with the latter through openings (openings 61a, 62a) a single passage passing through the wall 60,

- a second operative position in which the through opening 91 of the selector 90 is distanced with respect to at least one of said through openings of the outer and inner panels (61 , 62).

In detail, the through opening 91 of the selector 90, in the first operative position of the latter, is at least partly aligned with the through openings 61a, 62a of the outer panel 61 and of the inner panel 62 along a direction orthogonal to the development plane of at least one from among: the outer panel 61, the inner panel 62 and the selector 90. The single through opening is thus essentially defined by a series of at least partly aligned holes which essentially define a channel passing through the inner thickness of the wall 60. Vice versa, in the second operative position, the through opening 91 of the selector 90 is offset (not facing) at least one of the through openings of the outer and inner panels in a manner such that the same selector 90 can prevent the communication between the through openings 61a, 62a of the outer and inner panels.

As mentioned above, the selector 90 is extended parallel to the outer panel and to the inner panel; the selector 90 is movable between the first and second operative positions along at least one trajectory lying on a plane substantially parallel to the development planes of the outer panel 61 and/or of the inner panel 62. The movement trajectory can be of rectilinear type (like for the wall illustrated in figures 4, 8, 9, 18-20) or circular type (like for the wall illustrated in figures 15 and 17).

The movement of the selector 90 can be carried out by a user by means of manual intervention and in particular by means of the thrust of the same through the through opening 91 of the selector 90. In particular, the through opening

91 of the selector 90 is delimited by a perimeter edge, optionally closed, defining a gripping portion of the selector 90 itself which can be contacted by the user - through the through opening 61a of the outer panel and/or through the through opening 62a of the inner panel - for the manual movement of the selector 90 from the first to the second operative position, and vice versa.

The wall 60 can comprise a first and a second selector 90a, 90b. The first and second selectors are in accordance with the at least one above-described selector 90. The first and second selectors are made of sheet material and engaged in interposition between the outer panel 61 and the inner panel 62; each of said first and second selectors is extended along a main development plane parallel to the outer panel and to the inner panel. In detail, the first and the second selector 90 are parallel to each other and parallel to the outer and inner panels. In still more detail, the first and the second selector are facing, at least partly in contact with each other; the first selector 90a is directly interposed between the outer panel 61 and the second selector 90b while the second selector 90b is directly interposed between the inner panel and the first selector 91 .

The first and the second selector 90a, 90b are larger than the through openings 61a, 62a of the outer panel 61 and inner panel 62 in a manner such that said panels can engage the selectors without the same can exit outward from one of the through openings of the outer and inner panels. In detail, the first and the second selector 90a, 90b both have a surface area (extension) larger than the passage area of the through openings 61a, 62a of the outer and inner panels; said surface area being measured along the development plane of the respective selector. In still more detail, the first and the second selector 90a, 90b are perimetrically delimited by respective closed outer edges which, visible along a direction orthogonal to the development plane of the respective selector, at least partly contains the through opening 61 a of the outer panel 61 and the through opening 62a of the inner panel 62.

As is visible from the enclosed figures, the first and the second selector 90a, 90b are provided with respective through openings 92, 93 which are extended through the entire thickness of the respective selector. Each through opening 92, 93 is delimited by a perimeter edge which delimits a passage area. In detail, the perimeter edge of the through opening

92 of the first selector 90a is of closed type and is entirely contained within an outer perimeter edge delimiting the first selector 90a. For example, the ratio between surface area (extension) of the first selector 90a and the passage area of the through opening 92 of the same first selector is larger than 1 .5, optionally comprised between 2 and 10. In detail, the perimeter edge of the through opening 93 of the second selector 90b is of closed type and is entirely contained within an outer perimeter edge delimiting the second selector 90b. For example, the ratio between surface area (extension) of the second selector 90b and the passage area of the through opening 93 of the same second selector 90b is larger than 1.5, optionally comprised between 2 and 10.

As is visible from the enclosed figures, the through openings 92, 93 of the first and second selector can have a circular shape, for example substantially equal (at least regarding shape) to the through opening of the inner panel and/or of the outer panel. The through openings 92, 93 of the first and second selectors can alternatively have a different form, for example square, elliptical or extended along one or more trajectories. The through openings 92, 93 of the first and second selector can be different regarding shape and/or size. In detail, the through opening 92 of the first selector 90a defines a predetermined passage area larger than a passage area defined by the through opening 93 of the second selector 90b. Nevertheless, the passage area of the through opening 92 of the first selector is smaller than the passage area of the through opening 61 a of the outer panel 61 . The passage area of the through opening 62a of the inner panel can be larger and/or smaller than the passage area of the through openings of the first and second selector.

As for the above-described selector 90, the first and second selectors are relatively movable with respect to each other and relative to at least between the outer panel and the inner panel at least between the respective first and second operative positions. In the first operative position of the first selector, the latter has its through opening 92 at least partly facing the through openings 61a, 62a of the outer and inner panels 61, 62; in the same manner, in the first operative position of the second selector, the latter has its through opening 93 at least partly facing the through openings 61a, 62a of the outer and inner panels 61, 62. In the second operative position, both the selectors 90a, 90b have the through openings distanced with respect to at least one of said through openings of the outer and inner panels 61, 62.

In fact, when both the selectors (first and second) are in the respective first position, the through openings 92, 93 are at least partly aligned with the through openings 61a, 62a of the outer panel 61 and of the inner panel 62 along a direction orthogonal to the development plane of at least one between: the outer panel 61 and the inner panel 62 define a single passage passing through the wall 60, adapted to place in communication the through openings 61a, 62a of the outer and inner panels. The single through opening is essentially defined therefore by a series of at least partly aligned holes which essentially define a channel passing through the inner thickness of the wall 60.

Vice versa, when at least one between the first and second selectors is in the second operative position, at least one between said through openings 92 and 93 is offset (not facing) at least one of the through openings of the outer and inner panels in a manner such that the selector (first and/or second) can prevent the communication between the through openings 61a, 62a of the outer and inner panels.

As mentioned above, the first and the second selector 90a, 90b are extended parallel to each other and parallel to the outer panel and to the inner panel. In detail, the first and the second selector 90a, 90b are superimposed on each other and movable between the first and second operative positions along respective and different trajectories lying on a plane substantially parallel to the development planes of the outer panel 61 and/or of the inner panel 62. Such movement trajectories of the first and second selector 90a, 90b can be of rectilinear or circular type.

The movement of the first and second selector 90a, 90b can be carried out by a user by means of manual intervention and in particular by means of the thrust of the same through the through opening 92, 93 of the respective selector 90. In particular, the through openings of the first and second selectors are delimited by respective perimeter edges, optionally closed, defining respective gripping portions of the first and second selectors which can be contacted by the user - through the through opening 61 a of the outer panel 61 and/or through the through opening 62a of the inner panel 62 - for the manual movement of the first and second selector 90a, 90b from the first to the second operative position, and vice versa.

As described above, the through opening 61a of the outer panel 61 has a passage area larger than the passage area of the through opening 92 of the first selector 90a; in addition, the through opening 92 of the first selector has a passage area larger than the passage area of the through opening 93 of the second selector 90a. Due to the size variation of the through openings of the outer panel and of the first and second selector, the user can, through the outer panel 61, act both on the first and on the second selector for the movement of the latter between the first and second operative positions.

As described above, the at least one selector 90 (optionally the first and the second selector 90a, 90b) can be engaged directly between the outer panel 61 and the inner panel 62 without there being a further support element, i.e. in a manner such that the at least one selector is engaged within a seat defined directly and exclusively by the outer panel 61 and by the inner panel 62. Alternatively, the at least one selector 90 (optionally the first and second selectors 90a, 90b) can also be carried by at least one intermediate panel 63 as illustrated in the enclosed figures. In the following description, a first embodiment is described in which the wall comprises a single intermediate panel 63 and a single selector 90 and a second embodiment of the wall 60 comprising a first and second intermediate panels 63a, 63b carrying the first and second selectors 90a, 90b

In detail, in the first embodiment, the wall 60 comprises an intermediate panel 63 made of sheet material, extended along a main development plane, parallel to the outer panel 61 and inner panel 62: the main development planes of the outer, inner and intermediate panels are parallel to each other. The intermediate panel 63 is interposed between the outer panel 61 and the inner panel 62: the intermediate panel 63 on one side faces the outer panel and on the opposite side faces the inner panel 62.

The intermediate panel 63 can have a rectangular form. It is however possible to make an intermediate panel 63 having a different form, e.g. square, elliptical, semicircular, triangular or trapezoidal; in detail, the intermediate panel 63 has a shape, and optionally a size, substantially identical to the shape (and optionally the size) of the outer panel 61 and/or of the inner panel 62. In detail, the intermediate panel can have a surface area larger than 8 cm 2 , optionally comprised between 20 and 500 cm 2 ; the intermediate panel can further have a length equal to or larger than 5 cm, optionally comprised between 8 and 40 cm, and a width equal to or larger than 5 cm, optionally comprised between 8 and 40 cm. The intermediate panel 63 can be on one side directly integrally joined to the outer panel 61 by means of a first connection edge and on the opposite side directly integrally joined to the inner panel 62 by means of a second connection edge opposite the first connection edge. Alternatively, the intermediate panel 63 can be directly integrally joined only to the inner panel 62 by means of a connection edge: the inner panel 62 is in turn directly integrally joined to the outer panel 61 by means of a respective connection edge opposite the connection edge of the inner panel 62 and of the intermediate panel 63. In both of the above-described configurations, the outer panel 61, the inner panel 62 and the intermediate panel 63 are joined in a single piece to form a single body; as will be better described hereinbelow and as schematically illustrated in figures 10, 12 and 13, the wall 60 is made via folding of the intermediate panel 63 in interposition between the outer panel 61 and the inner panel 62. As is visible in the enclosed figures, the intermediate panel 63 comprises at least one groove 64 adapted to receive the selector 90; in fact, the groove 64 of the intermediate panel 63, together with the inner panel 62 and the outer panel 61, delimit a seat 65 within which the selector 90 is movable; the groove 64 passes through the thickness of the intermediate panel 63 and the selector 90 is entirely contained within said groove 64. In particular, the groove 64 is delimited by a perimeter edge with closed profile which, visible along a direction orthogonal to the main development plane of the intermediate panel 63, entirely contains the selector 90. The groove can have a substantially rectangular form (see for example figures 8, 9 and 20) or substantially circular (see for example figures 15 and 17); it is however possible to make a groove 64 having a different form, e.g. square, elliptical, trapezoidal. The selector 90 is at least partially counter-shaped with respect to the perimeter edge of the groove 64 of the intermediate panel 63: this configuration allows the groove to guide the movement of the selector 90 between the first and second operative positions. The intermediate panel 63 can also comprise at least one first and one second end stop element configured for limiting the movement of the selector 90 between the first and second operative positions; such end stop elements can alternatively be carried by the outer panel and/or by the inner panel.

In order to internally house the selector 90, the groove 64 has a passage area larger than the surface area of the selector 90 in a manner such to allow the movement of the selector itself within the groove 64 between the first and second operative positions. In particular, the ratio between the passage area of the groove 64 and the surface area of the selector 90 is larger than 1.05, in particular comprised between 1.1 and 7, still more particularly between 1.1 and 5; the surface area of the selector 90 and the passage area of the groove 64 are measured in the main development plane of the intermediate panel 63 carrying said selector 90. In particular, the groove 64 is delimited by a perimeter edge with closed profile which, visible along a direction orthogonal to the main development plane of the intermediate panel 63, entirely contains the selector 90.

As described above, the selector 90 has a surface area larger than the passage area of the through openings 61a, 62a of the outer panel 61 and of the inner panel 62; in particular, the outer perimeter edge which defines the surface area of the selector 90, in the first and in the second operative position of the selector 90 itself (such as also in the intermediate operative positions defined between said first and second operative positions), is configured for containing within its own profile - visible along a direction orthogonal to the development plane of the selector 90 - said through openings 61a, 62a of the outer and inner panels.

The ratio between the passage area of the groove 64 and the passage area of the through opening 61a of the outer panel 61 is larger than 2, optionally equal to or larger than 3, still more optionally comprised between 3 and 15. In the same manner, the ratio between the passage area of the groove 64 and the passage area of the through opening 62a of the inner panel 62 is larger than 2, optionally equal to or larger than 3, still more optionally comprised between 3 and 15.

The wall 60 can also comprise at least one weakening portion 69 configured for defining a locking condition in which the weakening portion itself integrally connects the at least one selector 90 with the at least one intermediate panel 63; in such configuration, the selector 90 is integrally joined to the intermediate panel 63 and is not movable relative to the latter. The weakening portion is configured for being broken following an external stress applied on the selector in order to allow the detachment (the separation) of the selector 90 from the intermediate panel 63 to define a movement condition in which the selector 90 is movable between the first and second operative positions, and vice versa. In fact, the weakening portion essentially defines a sealing element which maintains the selector 90 in a predetermined position until such weakening portion is intentionally broken, for example by a user. Such weakening portion 69 can therefore be employed in order to define a mechanism of the type to show the tampering of an attempted opening (crossing) of the wall 60. For example, if the selector 90 is maintained in the second operative position by the weakening portion, in order to be able to define the through channel the wall 60, a user must break the weakening portion in order to allow the movement of the selector from the second to the first operative position. The weakening portions 69 are schematically visible in the representations of the flat blanks illustrated in figures 1, 3, 11.

In the second embodiment, the wall 60 comprises a first intermediate panel 63a and at least one second intermediate panel 63b integrally joined by means of a connection edge (see figure 7). The first and second intermediate panels are extended along respective development planes that are substantially parallel to each other and parallel to the development planes of the outer panel 61 and of the inner panel 62: the first intermediate panel 63a is directly facing and at least partly in direct contact with the second intermediate panel 63b. In detail, the first and the second intermediate panel 63a, 63b are interposed between the outer panel 61 and the inner panel 62. The first intermediate panel 63a directly faces the outer panel 61 and is directly interposed between said outer panel 61 and the second intermediate panel 63b; the second intermediate panel 63b directly faces the inner panel 62 and is directly interposed between said inner panel 62 and the first intermediate panel 63a (figure 7). In still more detail, the outer panel, the inner panel, the first intermediate panel and the second intermediate panel are joined in a single piece: the wall 60 can be made via folding of the first and second intermediate panels 63a, 63b in interposition between the outer panel 61 and the inner panel 62.

The first and the second intermediate panel both have a rectangular form, and in particular have the same size. It is however possible to make intermediate panels that are different in shape and size. In the enclosed figures, a wall 60 is illustrated having intermediate panels substantially identical in shape and size to the outer panel 61 and to the inner panel 62.

As is visible in the enclosed figures, the first intermediate panel 63a comprises at least one groove 66 adapted to receive the first selector 90a; in fact, the groove 66 of the first intermediate panel 63a, together with the second selector 90b and with the outer panel 61, delimit a seat within which the first selector 90a is movable; the groove 66 passes through the thickness of the first intermediate panel 63a and the first selector 90a is entirely contained within said groove 66. In particular, the groove 66 is delimited by a perimeter edge with closed profile which, visible along a direction orthogonal to the main development plane of the first intermediate panel 63a, entirely contains the first selector 90. The groove 66 can have a shape that is substantially rectangular or substantially circular; It is however possible to make a groove 66 having a different form, e.g. square, elliptical, trapezoidal. The first selector 90a is at least partially counter-shaped with respect to the perimeter edge of the groove 66 of the first intermediate panel 63a: this configuration allows the groove 66 to guide the movement of the first selector 90a along the first trajectory between the first and second operative positions. The first intermediate panel 63a can also comprise at least one first and one second end stop element configured for limiting the movement of the first selector 90a between the first and second operative positions; such end stop elements can alternatively be carried by the outer panel and/or by the inner panel. In order to internally house the first selector 90, the groove 66 has a passage area larger than the surface area of the first selector 90a in a manner such to allow the movement of the first selector itself within the groove 66 between the first and second operative positions. In particular, the ratio between the passage area of the groove 66 and the surface area of the first selector 90 is equal to or larger than 1.05, in particular comprised between 1.1 and 7, still more particularly between 1.1 and 5; the surface area of the first selector 90a and the passage area of the groove 66 are measured in the main development plane of the first intermediate panel 63a carrying said first selector 90. In particular, the groove 66 is delimited by a perimeter edge with closed profile which, visible along a direction orthogonal to the main development plane of the first intermediate panel 63a, entirely contains the first selector 90a.

As described above, the first selector 90a has a surface area larger than the passage area of the through openings 61a, 62a of the outer panel 61 and of the inner panel 62; in particular, the outer perimeter edge which defines the surface area of the first selector 90a, in the first and in the second operative position of the first selector 90 itself (like also in the intermediate operative positions defined between said first and second operative positions), is configured for containing within its own profile - visible along a direction orthogonal to the development plane of the first selector 90 - said through openings 61a, 62a of the outer and inner panels.

The ratio between the passage area of the groove 66 and the passage area of the through opening 61a of the outer panel 61 is larger than 2, optionally equal to or larger than 3, still more optionally comprised between 3 and 15. In the same manner, the ratio between the passage area of the groove 66 and the passage area of the through opening 62a of the inner panel 62 is larger than 2, optionally equal to or larger than 3, still more optionally comprised between 3 and 15.

Also the first selector can be connected to the first intermediate panel 63 by means of at least one weakening portion 69 in accordance with that described above. As is visible in the enclosed figures, the second intermediate panel 63b comprises at least one groove 67 adapted to receive the second selector 90b; in fact, the groove 67 of the second intermediate panel 63b, together with the first selector 90a and with the inner panel 62, delimit a seat within which the second selector 90b is movable; the groove 67 passes through the thickness of the second intermediate panel 63b and the second selector 90b is entirely contained within said groove 67. In particular, the groove 67 is delimited by a perimeter edge with closed profile which, visible along a direction orthogonal to the main development plane of the second intermediate panel 63b, entirely contains the second selector 90b. The groove 67 can have a substantially rectangular or substantially circular form; it is however possible to make a groove 67 having a different form, e.g. square, elliptical, trapezoidal. The second selector 90b is at least partially counter-shaped with respect to the perimeter edge of the groove 67 of the second intermediate panel 63b: this configuration allows the groove 67 to guide the movement of the second selector 90b along the second trajectory between the first and second operative positions. The second intermediate panel 63b can also comprise at least one first and one second end stop element configured for limiting the movement of the second selector 90b between the first and second operative positions; such end stop elements can alternatively be carried by the outer panel and/or by the inner panel.

In order to internally house the second selector 90b, the groove 67 has a passage area larger than the surface area of the second selector 90b in a manner such to allow the movement of the second selector itself within the groove 67 between the first and second operative positions. In particular, the ratio between the passage area of the groove 67 and the surface area of the second selector 90b is equal to or larger than 1.05, in particular comprised between 1.1 and 5, still more particularly comprised between 1 .1 and 3; the surface area of the second selector 90b and the passage area of the groove 67 are measured in the main development plane of the second intermediate panel 63b carrying said second selector 90b. In particular, the groove 67 is delimited by a perimeter edge with closed profile which, visible along a direction orthogonal to the main development plane of the second intermediate panel 63b, entirely contains the second selector 90b.

As described above, the second selector 90b has a surface area larger than the passage area of the through openings 61a, 62a of the outer panel 61 and of the inner panel 62; in particular, the outer perimeter edge which defines the surface area of the second selector 90b, in the first and in the second operative position of the second selector 90b itself (such as also in the intermediate operative positions defined between said first and second operative positions), is configured for containing within its own profile - visible along a direction orthogonal to the development plane of the second selector 90b - said through openings 61a, 62a of the outer and inner panels.

The ratio between the passage area of the groove 67 and the passage area of the through opening 61a of the outer panel 61 is larger than 2, optionally equal to or larger than 3, still more optionally comprised between 3 and 15. In the same manner, the ratio between the passage area of the groove 67 and the passage area of the through opening 62a of the inner panel 62 is larger than 2, optionally equal to or larger than 3, still more optionally comprised between 3 and 15. Also the second selector 90b can be connected to the first intermediate panel 63a by means of at least one weakening portion 69 in accordance with that stated above.

Process for making the wall 60

Also forming the object of the present invention is a process for making a wall 60 in accordance with the above-reported description and/or in accordance with the enclosed claims. The process comprises the steps of.

- preparing at least one first flat sheet 81 comprising at least one through notch 81 a,

- preparing at least one second flat sheet 82 comprising at least one through notch 82a,

- preparing at least one third flat sheet 83 comprising at least one through notch 83a,

- superimposing the first and second flat sheets 81, 82 in a manner such that the same are substantially parallel to each other such that they can respectively define the outer panel 61 and the inner panel 62 of the wall 60, in which the through notch of the first sheet defines the through opening 61a of the outer panel 61 while the through notch of the second sheet defines the through opening 62a of the inner panel 62,

- positioning the third sheet 83 in interposition between the first and second sheets superimposed in a manner such that said third sheet defines said selector 90.

Following the step of superimposition of the first and second sheet, the process can comprise a step of constraining said sheets, e.g. by means of gluing, in a manner such to be able to stably maintain the outer panel 61 and the inner panel (formed by the first and second superimposed sheets) engaged with each other and arranged parallel to each other.

The process can also comprise a step of preparing at least one fourth sheet 84 comprising at least one through notch 84a; the first sheet 81 , the second sheet 82 and the fourth sheet 84 are integrally joined by means of connection edges and aligned along a predetermined direction. The process can comprise a step of folding the first sheet 81, the second sheet 82 and the fourth sheet 84 at the connection edges so as to prepare the fourth sheet in interposition between the first and second sheets: following the folding step - the first, second and fourth sheets respectively define the outer panel 61, the inner panel 62 and the intermediate panel 63 of the wall 60. The through notch 84a of the fourth sheet, following the folding step, defines the groove 64 of the intermediate panel 63. In detail, the process comprises a step of cutting the fourth sheet to define on the same the through notch 84a during which the third sheet 83 for defining the selector 90 is obtained.

As is visible for example in figures 1, 3, 10-14, 16 and 18, the first sheet 81, the second sheet 82 and the fourth sheet 84 are integrally joined to define a single flat sheet 80; the process comprises a die-cutting step during which the through notches 81a, 82a, 84a are simultaneously executed of the first, second and fourth sheets and the through notch 83a of the third sheet obtaining during the notching of the fourth sheet 84: the die-cutting step defines - at the connection edges of the first, second and fourth sheets - creases for the folding of said sheets.

The process, following the die-cutting step, comprises the step of folding said single flat sheet 80 so as to prepare the fourth sheet 84 in interposition between the first and second sheets 81, 82 to define the intermediate panel 63 interposed between the outer panel 61 and the inner panel 62 of the wall 60: the third sheet 83 is folded together with the fourth sheet between the first and second sheets in a manner such to obtain the selector 90 arranged within the groove 64 of the intermediate panel 63.

The step of preparing the at least one fourth sheet 84 comprises the preparation of two fourth sheets 84', 84" integrally joined together by means of a connection edge and respectively integrally joined to the first and second sheet 81, 82: said fourth sheets 84', 84" comprising respective through notches 84a', 84a". The process comprises the positioning of the fourth sheets in interposition between the first and second sheets 81, 82 folded in a manner such that said two fourth sheets can respectively define the first and the second intermediate panel: the through notches of the two fourth sheets define the grooves 66, 67 of the first and second intermediate panel. The through notches of the fourth sheets allow obtaining the first and second selectors 90a, 90b from the latter.

The first sheet 81, the second sheet 82 and the two fourth sheets 84', 84" are integrally joined to define the single flat sheet 80. The process comprises a die-cutting step during which the through notches 81a, 82a, 84a', 84a” are simultaneously executed of the first, second and two fourth sheets: the die-cutting step defines - at the connection edges of the first, second and two fourth sheets - creases for the folding of said sheets. From the attainment of the notches 84a', 84a" by means of the die-cutting, two third sheets 83', 83" are attained, respectively adapted to define the first and the second selector 90a, 90b. The third sheets 83', 83" comprise respective through notches 83a', 83a" adapted to define the through opening 92 of the first selector 90a and the through opening 93 of the second selector 90b. Following the die-cutting step, the single flat sheet 80 is folded so as to prepare the two fourth sheets in interposition between the first and second sheets 81, 82 to define the first and the second intermediate panel 63a, 63 placed in interposition between the outer panel 61 and the inner panel 62 of the wall 60. The first and second selectors 90a, 90b obtained from the through notches 84a', 84a" of the two fourth sheets are folded together with the two fourth sheets between the outer and inner panels. Package 100

Reference number 100 overall indicates a child-proof package for containing products such as for example: drugs, cosmetics, cleaning products (detergents for linens/sheets and dishes), foods and tobacco-based products (cigars and cigarettes).

The package 100 comprises a container 1 made of sheet material, e.g. paper, defining a compartment 3 for housing at least one product. The container 1 has a predetermined number of lateral walls 4 defining at least one opening 5 delimited by a free edge 6: the opening 5 is configured for allowing the insertion and the removal of the product from the container 1. The container 1 can have a quadrangular prismatic form as illustrated in the enclosed figures, though it is also possible to make a container 1 having different shape. In detail, the container 1 can comprise a lateral front wall 4a and a lateral rear wall 4b facing and parallel to each other: the front wall 4a and the rear wall 4b are connected together by means of a first and a second lateral wall 4c, 4d, also facing and parallel to each other. The front wall 4a is distanced and opposite the rear wall 4b; the first and second lateral wall 4c, 4d are also spaced and opposite each other. The ends of the front, rear and lateral walls (4a, 4b, 4c, 4d) define the opening 5, delimited by the free edge 6. The container 1 also comprises a bottom wall 9 having rectangular shape, from which the lateral walls 4 emerge, starting from a perimeter edge of the bottom wall 9. The container 1 then comprises a single opening 5 defined opposite the bottom wall 9.

The package 100 also comprises a case 102, that can also be made of sheet material, e.g. paper, and having a predetermined number of lateral walls 104 defining at least one access 105 delimited by a free edge 106 configured for allowing the passage of the container 1. The predetermined number of lateral walls 104 of the case 102 delimits an internal volume 103 configured for receiving at least part of the container 1; indeed, the access 105 is configured for placing the internal volume 103 in communication with the external environment, as well as allowing the insertion and the removal of the container 1 from said internal volume 103.

In particular, the case 102 and the container 1 are relatively movable with respect to each other at least between:

- a closed condition in which the case 102 obstructs the opening 5 of the container 1, and

- an open condition in which the case 102 allows the communication between the compartment 3 and the external environment.

The relative movement between case 102 and container 1 can be obtained by moving both parts, i.e. both the case and the container, or it can be obtained by means of the movement of only one of the parts: for example it is possible to maintain fixed the container and only move the case relative to the container. In detail, the container 1, in the closed condition, is at least partly arranged in the internal volume 103: the case 102, in such condition, prevents the insertion and the removal of products from the container. In the open condition, the case 102 allows the removal of the products from the container. As schematized in figure 1, the case 102 and the container 1 can be distinct and completely separatable elements. It is however possible to make a case engaged via rotation with the container in a manner such that the same case is still movable between the closed condition and opening, and vice versa.

During the passage from the closed condition to the open condition, and vice versa, the container 1 and the case 102 relatively slide close to or away from each other: during such relative movement, the container 1 is placed at least partly within the case and relatively translates (by movement of at least one between said container and case) in a manner such that the bottom wall 9 of the container 1 is moved close to or away from a top wall 109 of the case 102 from which the predetermined number of lateral walls 104 emerge.

In detail, the case 102 has a structure at least partly counter-shaped with respect to the container 1 in a manner such that, in the closed condition, the case 102 is fit outside the container 1. In detail, the case 102 comprises a front wall 104a and a rear wall 104b that are opposite each other and connected by means of a first and a second lateral wall 104c and 104d, also spaced and opposite each other. In detail, also the case 102 has a rectangular prismatic form: the front wall 104a and the rear wall 104b (with square or rectangular shape) are facing and parallel to each other and connected to each other by means of the first and the second lateral walls 104c, 104d (with square or rectangular shape) also facing and parallel to each other. In the closed condition:

- the front walls 4a, 104a, respectively of the container and of the case, directly face each other,

- the rear walls 4b, 104b, respectively of the container and of the case, directly face each other,

- the first lateral walls 4c, 104c, respectively of the container and of the case, directly face each other,

- the second lateral walls 4b, 104d, respectively of the container and of the case, directly face each other.

The case 102 then comprises a single access 105 defined opposite the top wall 109. The top wall 109 is configured for being abutted, in the closed condition, against the free edge 6 of the opening 5 in order to obstruct the latter, as visible in figure 6.

As mentioned above, the case 102 is counter-shaped with respect to the container 1 . The counter-shaped configuration of the container 1 and the case 102 allows the lateral walls of the case 102 to slide (relatively) externally side-by-side the lateral walls 4 of the container 1 during the passage from the closed condition to the open condition and vice versa. In order to allow such relative movement, the case 102 has a size slightly larger than the container 1, sufficient for allowing the insertion of the latter in the internal volume 103.

The case 102 can comprise the wall 60 which can define at least one lateral wall 104 of the predetermined number of lateral walls of the case 102. In such condition, the outer panel 61 of the wall 60 defines at least one part of an outer surface of the case while the inner panel 62 defines at least one part of an inner surface of the case delimiting said internal volume 103. In the enclosed figures, a configuration of the case is illustrated in which the wall 60 defines the rear wall 104b of the case. In such configuration, the selector 90 (optionally the first and the second selector 90a, 90b) is arranged substantially in the internal volume 103 and movable via sliding within the latter between the first and second operative positions, and vice versa. In fact, the at least one selector is engaged via sliding between an outer wall of the case, defined by the outer panel 61 and an inner wall defined by the inner panel 62.

The package 100 also comprises at least one safety device 11 comprising:

- at least one first coupling portion 12 carried by the case 102 and at least partly arranged in the internal volume 103,

- at least one second coupling portion 13 carried by the container 1 and arranged outside the compartment 3.

The first and second coupling portions 12, 13 are configured for being stably engaged with each other outside the container 1, in the closed condition, to define a locking condition of the safety device 11 in which the first and second coupling portions 12, 13 prevent a container and case from passing from the closed condition to the open condition. The first coupling portion 12 is engaged with the lateral wall 104 of the case 102 defined by the wall 60, i.e. carrying the at least one selector 90 (optionally the first and second selectors). In particular, the first coupling portion 12 is defined on the inner panel 62 of the wall 60 which defines at least one lateral wall 104 of the case.

The first coupling portion 12 comprises at least one tab 12a defining an undercut delimited by at least one gripping edge 12b entirely placed in the internal volume 103, distinct and distanced from the free edge 106 of the access 105. In detail, the tab 12a defines at least one part of the inner panel 62 and hence integrally joined to the lateral wall 104 of the case 104. In detail the tab 12a, and hence the gripping edge 12b, is obtained by means of cutting, optionally through of the inner panel 62; the undercut delimited by the gripping edge 12b is adapted to cooperate with the second coupling portion 13: the gripping edge 12b is always distinct and distanced from the free edge 106 of the access 105. The gripping edge 12b of the first coupling portion 12 is arranged in interposition between the top wall 109 and the access 105 of the case 102; the gripping edge 12b of the first coupling portion 12 has a substantially "V” or "C” shape whose concavity is directed opposite with respect to the free edge 106 of the case 102.

As mentioned above, the safety device 11 can comprise at least one first coupling portion 12. In detail, the safety device 11 can comprise at least one of the following:

- at least one of said first coupling portion 12 carried by the front wall 104a of the case 102,

- at least one of said first coupling portion 12 carried by the rear wall 104b of the case 102 (in the illustrated condition at least partly by the wall 60),

- at least one of said first coupling portion 12 carried by the first lateral wall 104c of the case 102,

- at least one of said first coupling portion 12 carried by the second lateral wall 104c of the case 102.

In the enclosed figures, a safety device 11 was for example illustrated, comprising a first coupling portion 12 carried by the front wall 104a and at least one respective first coupling portion 12 carried by the rear wall 104b defined by the wall 60: said first coupling portions 12 are placed opposite each other. The gripping edge 12b of the first coupling portion 12 is arranged in proximity to the through opening 62a of the inner panel 62 of the wall 60 of the case 102.

As mentioned above, the safety device 11 also comprises at least one second coupling portion 13. In particular, the safety device 11 can comprise only one second coupling portion 13 configured for cooperating con one or more of said first coupling portions 12. Alternatively, the safety device 11 can comprise a second coupling portion 13 for each first coupling portion 12 (configuration illustrated in the enclosed figures).

The second coupling portion 13 is engaged with at least one lateral wall 4 of the container 1 and emerges from the latter according to a direction exiting from the compartment 3. The second coupling portion 13 comprises at least one panel 13a projecting from the lateral wall 4 to define an undercut delimited by at least one gripping edge 13b placed outside the compartment 3, distinct and distanced from the free edge 6 of the opening 5. The panel 13a can have a shape that is substantially triangular or substantially trapezoidal or substantially "V" or "C" shaped: in which the gripping edge 13b has at least one section, optionally two rectilinear sections, tilted with respect to the free edge 6 of the opening 5 optionally by an angle comprised between 20° and 80°, still more optionally by an angle comprised between 30° and 70°. In more detail, the free edge 13b of the panel 13a has a substantially "V” or "C” shape whose concavity is directed towards the free edge 6 of the container. In detail, the panel 13a is extended along one plane and directly faces the lateral wall 4 of the container 1 directly carrying the panel 13a; the panel 13a can be tilted with respect to the lateral wall 4 directly carrying said panel 13a by an angle smaller than 40°, optionally by an angle comprised between and 30°. The angle being measured between the surface of the panel 13a directly facing the lateral wall 4 and the same lateral wall 4 of the container 1 directly carrying (directly integrally joined) said panel 13a. The second coupling portion 13 is defined directly on the lateral wall 4: the second coupling portion forms at least part of the lateral wall 4. In detail, the panel 13a is obtained by means of the through cut of the lateral wall 4 in a manner such that, on the same, it is possible to extract the panel 13a that is projecting with respect to said lateral wall. In such configuration, the panel 13 can be extended from the lateral wall 4, distanced from the free edge 6, moving away from the latter by an angle smaller than 40°, optionally comprised between and 30°, with respect to the lateral wall 4 from which the same panel 13a has been obtained. In detail, the inner panel 13a is distinct and distanced from the free edge 6 of the container; in fact, the panel 13a is attained by means of notching an outer wall of the same container in a manner such that said panel has an attachment edge 13c completely separated (distanced) from the free edge 6 of the container (see for example figures 4 and 5).

Each second coupling portion 13 comprises one and only one panel 13a having a shape substantially triangular or in any case pointed adapted to cooperate with the first coupling portion 12.

The safety device 11 can comprise at least one second coupling portion 13. In detail, the safety device 11 can comprise at least one of the following:

- at least one of said second coupling portion 13 carried by the front wall 4a of the container 1,

- at least one of said second coupling portion 13 carried by the rear wall 4b of the container 1,

- at least one of said second coupling portion 13 carried by the first lateral wall 4c container 1,

- at least one of said second coupling portion 13 carried by the second lateral wall 4c of the container 1 .

In the enclosed figures, a non-limiting configuration of the invention is illustrated in which the safety device 11 comprises a second coupling portion 13 carried by the front wall 4a and a respective second coupling portion 13 carried by the rear wall 4b: said second coupling portions 13 are placed opposite each other.

In an exemplifying embodiment, the panel 13a can comprise at least two portions, each of which configured for being engaged respectively with one of said tabs 12a to define the locking condition of the container 1 and of the case 102. Such portions of the panel 13a can also have a shape that is substantially triangular or substantially trapezoidal). The gripping edge of each of said portions defines a gripping edge having shape that is substantially "V" shaped whose concavity is directed towards the free edge 6 of the opening 5.

In the configuration illustrated in the enclosed figures, the second coupling portion 13 carried by the front wall 4a of the container 1 is configured for cooperating, in the closed condition, with the first coupling portion 12 carried by the front wall 104a of the case while the second coupling portion 13 carried by the rear wall 4b of the container 1 is configured for cooperating, in the closed condition, with the first coupling portion 12 carried by the rear wall 104b of the case.

In the closed condition the undercut defined by the panel 13a of the second coupling portion 13 is stably engaged with the undercut of the tab 12a of the first coupling portion 12 to define said locking condition. In the locking condition, the safety device prevents the case and the container from passing from the closed condition to the open condition. In fact, due to the presence of the first and second coupling portion, the safety device 11 stably maintains the package in the closed condition, preventing the access from outside to the products housed in the container 1. Figures 6 and 7 schematically illustrate the engagement between the first and second coupling portion 12, 13 (locking condition of the safety device 11); as is visible, in the locking condition, the second coupling portion 13 can be at least partly interposed between the first coupling portion 12 and the lateral wall 104 of the case 102, carrying said first coupling portion, to define an undercut adapted to limit the moving away movement between the case 102 and the container 1 so as to prevent the passage from the closed condition to the open condition. Alternatively, in the locking condition, the free edge 13b of the panel 13a can be at least partly abutted against the gripping edge 12b of the first coupling portion 12 to define an undercut adapted to limit the moving away movement between the case 102 and the container 1 so as to prevent the passage from the closed condition to the open condition.

As mentioned above, the package 100 comprises the wall 60 which defines at least part of a lateral wall 104 of the case 102 directly carrying the first coupling portion and hence facing the lateral wall 4 of the container carrying the second coupling portion 13. In such configuration, the selector 90 (optionally the first and the second selector 90a, 90b) is at least in part facing the second coupling portion 13; the selector 90 (optionally the first and the second selector 90a, 90b), when arranged in the first operative position, defines the through passage of the wall 60 (hence of the lateral wall 104 of the case 102) adapted to allow, in said closed condition, the access from the external environment to the internal volume 103 of the case in order to allow the unlocking of the first and second coupling portion and the consequent passage of the case and the container from the closed condition to the open condition. In detail, the selector 90 (optionally the first and the second selector 90a, 90b), when arranged in the first operative position, defines said through opening configured for allowing a user to intervene (manually or also with the suitable opening device adapted to pass through said through opening) from outside the package 100 directly on the panel 13a of the second coupling portion 13 in order to allow, in the closed condition of the case and the container, the disengagement of the latter from the first coupling portion 12 and thus allow the passage of the case and the container from the closed condition to the open condition.

In still more detail, the selector 90 is movable from the second to the first operative position in order to define a kind of channel passing through the lateral wall 104 of the case through which a user can access, in the closed condition of the case and the container and from outside the package, the internal volume 103 of the case in order to intervene on the first and/or second coupling portion (in the enclosed figures, a configuration of the package is illustrated in which the user can intervene on the second coupling portion 13) in order to allow the disengagement thereof. The disengagement can occur by means of a thrust action of the panel 13a according to a direction entering the compartment 3 of the container in a manner such that said panel 13a can be moved away and hence uncoupled from the undercut of the first coupling portion 12.

In fact, the through channel definable by the selector 90 when placed in the first operative position allows a user, at least in the locking condition of the safety device 11, intervention from outside the package 100 directly on at least one of said first and second coupling portions 12, 13 manually and/or by means of an opening device insertable through said through channel, or through the through openings (61a, 62a, 91) of the outer panel, of the inner panel and of the selector defining the lateral wall of the case.

Vice versa, when the selector 90 (or at least one between the first and second selectors 90a, 90b) is in the second operative position, the selector 90 itself prevents the communication between the through openings 61a, 62a of the outer and inner panels in a manner such to prevent a user from accessing, from the external environment, the internal volume 103 of the case (through said through openings) and hence preventing the disengagement between the first and second coupling portions. The safety device 11 and hence configured for preventing a child from opening the package, hence preventing the access to the products contained therein.

The through opening 61a of the outer panel 61 is configured for allowing, in the closed condition of the case and the container and from outside the package, intervention on the selector 90 (optionally on the first and second selectors 90a, 90b) in order to allow the movement thereof from the first to the second operative position, and vice versa.

For example, the user through the through opening, during the closed condition of the package, can act thrustingly directly on the panel 13a in a manner such to be disengaged from the tab 12a; the thrust of the user can occur so as to move the panel 13a close to the compartment of the container and away (in disengagement) from the tab 12a; in fact, the thrust generated by the user on the panel 13a allows moving away the first and second coupling portions until the panel 13a is disengaged from the tab 12a.

In the enclosed figures, a package 100 was illustrated in which only the lateral rear wall 104b is at least partly defined by the wall 60. The package can however comprise a first coupling portion and a second coupling portion respectively carried by the lateral front wall 104a of the case and a lateral front wall 4a of the container 1. Such coupling portions can be disengaged by means of an unlocking portion 17 configured for defining at least one through access 18 on the lateral front wall 104a: the unlocking portion 17 is configured for allowing, at least in the locking condition of the safety device 11, the direct access, from outside the package, to at least one between said first and second coupling portions 12, 13 in order to allow the disengagement thereof and hence allow the passage of the case 102 and the container from the closed condition to the open condition.

Also the unlocking portion 17 is configured for allowing a user, at least in the locking condition of the safety device 11, intervention from outside the package 100 directly on at least one of said first and second coupling portion 12, 13 (in this case carried by the front walls 104a, 4a of the case and the container) manually and/or by means of an opening device insertable through the through access 18 definable by said unlocking portion. In still more detail, the unlocking portion 17 is configured for allowing, at least in the locking condition of the safety device 11, intervention from outside the package 100 directly on the panel 13a of at least one of said second coupling portions 13.

The presence of the unlocking portion 17 essentially defines a second portion through which the user can have access to the internal volume 103 for the disengagement of the coupling portions 12, 13. In other words, the first and second coupling portions 12, 13 carried by the rear lateral walls of the case and the container essentially define a first safety device 11 while the first and second coupling portions 12, 13 carried by the lateral front walls of the case and the container essentially define a second safety device 11 ; the user has the possibility to intervene on the first safety device through the wall 60 and in particular upon action of the selector 90 in order to define the channel passing through the lateral rear wall 104b of the case, while such user has the possibility to intervene on the second safety device through the through access 18 of the unlocking portion 17.

The unlocking portion 17 can comprise a through access 18 defined on the lateral front wall 104a of the case 102: the through access 18 is configured for allowing the communication between the external environment and the internal volume 103 and specifically allows a user to reach the panel 13a of the second unlocking portion 17 in the locking condition of the safety device 11 and hence in the closed condition of the case and the container.

The package can also comprise at least one tear tab arranged to cover the through opening 61a of the wall 60 and hence to cover the selector 90 (optionally of the first and second selector 90a, 90b, if present); the tear tab is configured for preventing the direct access to the selector 90; the tear tab is configured for being removed from the package in order to show an attempt to access the selector for the opening of the package. If the unlocking portion 17 is also present, the package can comprise a further tear tab placed to cover/close the through access 18.

Process for making the package 100

Also forming the object of the present invention is a process for making a package 100 in accordance with one or more of the enclosed claims and/or in accordance with the above-reported description. The process provides for the preparation of the case 102 attainable by means of a first flat blank 50 made of sheet material, optionally paper. The first blank 50 comprises:

- a central sheet 51,

- a predetermined number of lateral sheets 52 integrally joined to the central sheet 51 and emerging from the latter starting from a perimeter edge,

- at least one peripheral sheet 53 engaged with at least one of said lateral sheets 52 opposite the central sheet 51 . The central sheet 51 has a polygonal shape, optionally rectangular or square. From each side of the central sheet 51 is extended a lateral sheet 52, also having a polygonal shape, optionally rectangular or square. The preparation of the case 102 comprises the sub-step of folding the predetermined number of lateral sheets 52 in order to define the predetermined number of lateral walls 104 of the case 102. In detail, the lateral sheets are folded with respect to the central sheet 51 in a manner such that from the flat blank it is possible to obtain a case having three-dimensional shape. The lateral sheets 52 are constrained to each other in a manner such that the case 102 can maintain its three- dimensional form; the lateral sheets 52 can be constrained directly to each other by means of glue or any one adhesive material. Alternatively, the blank 50 can be provided with at least one connection sheet 55 which integrally joins two adjacent lateral sheets 52 (figure 2); in such configuration, the process - simultaneously with the folding of the lateral sheets 52 - provides for superimposing and joining, e.g. by means of gluing, the connection sheet 55 to adjacent folded lateral sheets: in this manner, the case can maintain its three-dimensional form with the lateral sheets 52 which define the lateral walls 104 and the central sheet to define the top wall 109.

The process also provides for the definition of the at least one first coupling portion 12 by means of the at least one peripheral sheet 53. In detail, the peripheral sheet 53 is integrally joined ad at least one lateral sheet 52 of the first blank 50; the peripheral sheet 53 of the first blank 50 emerges from a perimeter edge of at least one lateral sheet 52 of the first blank 50 itself on the side opposite the central sheet 51 of the first blank. The first coupling portion 12 is made via folding of the peripheral sheet 53 of the first blank 50 on top of the lateral sheet 52 of the same first blank 50 with which said peripheral sheet 53 is integrally joined. Following the folding of the peripheral sheet, at least one part of this is constrained, for example by means of gluing, to a part of the lateral sheet to which it is directly integrally joined (directly to the lateral wall 104). The folding of the at least one peripheral sheet 53 can be executed previously, simultaneously or subsequently with respect to the folding and constraining of the lateral sheets 52.

The process for making the package also comprises the process for making the above-described wall 60 in a manner such that the wall 60 can define at least one lateral wall 104 (in the illustrated case in the enclosed figures, the lateral rear wall 104b). As is visible from figures 3, 11, 14, 16 and 18, the first flat sheet 81 is integrally joined to the central sheet 51 of the first blank 50: the second sheet 82 is opposite the central sheet 51 of the first blank on the side opposite the first sheet 81 . The process comprises the steps of:

- folding the predetermined number of lateral sheets 52, together with the first and second sheets 81, 82 in order to define the at least one lateral wall 104 of the case 102 comprising the first coupling portion 12,

- positioning the third sheet 83 in interposition between the first and second sheets superimposed in a manner such that said third sheet defines said selector 90.

If the blank 50 also comprises the at least one third and one fourth sheet 83, 84 - defined by means of a single die cutting step - these sheets are folded between the first and second sheets in a manner such that they can define, at the end of the folding of the blank, the intermediate panel 63 and the selector 90.

The central sheet 51, the lateral sheets 52, the peripheral sheet 53, together with the first, second, third and fourth sheets of the first blank 50 can be integrally joined to essentially define a blank of a single sheet obtainable by means of a single step of die-cutting a precursor sheet, e.g. at least partly in paper material. The case 102 is thus obtainable by means of steps of folding and gluing of the single blank (first flat blank 50).

As described above, the case 102 can comprise the unlocking portion 17 which is obtainable by means of the preparation of a notch 56 of at least one lateral sheet 52 of the first blank 50: the notch 56 is of the type passing through the lateral wall 52 and is executed on the lateral wall 52 carrying the peripheral sheet 53. In particular, the notch 56 is executed at the peripheral sheet 53.

The process provides for the preparation of the container 1 attainable by means of a second flat blank 70 made of sheet material, optionally paper. The first blank 70 comprises:

- a central sheet 71,

- a predetermined number of lateral sheets 72 integrally joined to the central sheet 71 and emerging from the latter starting from a perimeter edge,

The central sheet 71 has a polygonal shape, optionally rectangular or square. From each side of the central sheet 71, a lateral sheet 72 is extended, it too having a polygonal shape, optionally rectangular or square. The preparation container 1 comprises the sub-step of folding the predetermined number of lateral sheets 72 in order to define the predetermined number of lateral walls 4 of the container 1 . In detail, the lateral sheets 72 are folded with respect to the central sheet 71 in a manner such that from the flat blank 70, it is possible to obtain a container 1 having three- dimensional shape. The lateral sheets 72 are constrained to each other in a manner such that the container 1 can maintain its three-dimensional form; the lateral sheets 72 can be constrained directly to each other by means of glue or any one adhesive material. Alternatively, the blank 70 can be provided with at least one connection sheet 75 which integrally joins two adjacent lateral sheets 72; in such configuration, the process - simultaneously with the folding of the lateral sheets 72 - provides for the superimposition and the joining, for example by means of gluing, of the connection sheet 75 to adjacent folded lateral sheets 72: in this manner, the container 1 can maintain its three- dimensional form with the lateral sheets 72 which define the lateral walls 4 and the central sheet 71 to define the bottom wall 9.

The process also provides for the definition of the at least one second coupling portion 13. Each second coupling portion 13 can be obtained by means of a step of cutting one of said lateral sheets 72 of the second blank 70 in order to define, directly on said lateral sheet, at least one through notch 76 adapted to define the panel 13a of the second coupling portion 13. The second blank 70 can comprise at least one peripheral sheet 73 integrally joined to the lateral sheet 72 carrying the notch 76 for defining the second coupling portion. The peripheral sheet 73 emerges from the lateral sheet to which it is directly integrally joined on the side opposite the central sheet 71, as is visible in figure 2. The peripheral sheet 73 is folded on top of lateral sheet 72 of the same second blank 70 to which said peripheral sheet 73 is integrally joined; following the folding, the peripheral sheet 73 is at least partly superimposed and facing the lateral sheet 72 with which it is directly integrally joined. Following the folding of the peripheral sheet 73, at least one part of this is constrained, e.g. by means of gluing, with a part of the lateral sheet 72 to which it is directly integrally joined (directly to the lateral wall 4). The folding of the at least one peripheral sheet 73 can be executed - previously, simultaneously or subsequently - with respect to the folding and constraining of the lateral sheets 72. In one embodiment, the peripheral sheets 73 are folded before the folding of the lateral sheets 72; only following the folding of the peripheral sheets 73, the process provides for the folding and constraining of the lateral sheets 72 in a manner such that, simultaneously with the definition of the lateral walls 4, the definition of the second coupling portion 13 is obtained. The peripheral sheet 73 is configured for defining a support of the lateral sheet 72 carrying the notch 76.

The central sheet 71 , the lateral sheets 72 and the possible peripheral sheet 73 (if present) of the second blank 70 can be integrally joined to define a single blank made of a single piece, for example at least partly made of paper material. The container 1 is therefore obtainable by means of steps of folding and gluing of a single sheet blank (first flat blank 70). The second blank 70 can be obtained, by means of one or more of die-cutting steps, a single precursor sheet. The first and second blank 50, 70 - although obtainable by means of a step of die-cutting a single sheet - are separate pieces that are machinable, separatable, in order to obtain a case 102 separated from the container 1.

Container

Also forming the object of the present invention is a container for containing products. The container comprises at least one wall 60 in accordance with the above-reported description and/or in accordance with the enclosed claims. The container comprises a storage defining an internal volume and configured for housing one or more products. The storage comprises a predetermined number of lateral walls defining at least one passage opening delimited by a free edge: the passage opening is configured for placing the internal volume of the storage in communication with the external environment.

The container also comprises a closure system constrained via rotation to the free edge of the storage and movable via rotation relative to the storage between: - a closed position in which the closure system prevents the communication between the internal volume of the storage and the external environment,

- an open position in which the closure system allows the communication between the internal volume and the external environment.

The container also comprises a safety device comprising a first and a second coupling portion respectively carried by the closure system and a lateral wall of the storage and configured for being stably engaged with each other in the closed condition of the closure system. In particular, the second coupling portion carried by the storage is arranged entirely in the internal volume of said storage and is configured for receiving in engagement the first coupling portion, it too insertable within the storage, in the closed condition of the closure system. The first and second coupling portions are configured for stably maintaining the container in the closed condition and preventing the opening thereof.

The container comprises the wall 60 adapted to define at least one part of the wall of the storage directly carrying the second coupling portion. The wall 60 is configured for defining, due to the movement of the selector, the through opening adapted to allow a user to access, from outside the container, the internal volume of the storage in a manner such that the user can act on at least one of said first and second coupling portions in order to allow the disengagement thereof and hence the passage of the closure system from the closed condition to the open condition. In fact, the wall 60 is configured for defining a system for opening the container which allows the user to reach, from outside the container, the coupling portions for the disengagement thereof.

Method for closing the package 100

Also forming the object of the present invention is a method for closing a package 100 in accordance with one or more of the enclosed claims and/or in accordance with the above-reported description. The method comprises a first step of positioning the case 102 outside the container 1 in a manner such that the latter can be at least partly housed in the internal volume of the case 102. Before the step of positioning the case 102 outside the container 1 - said the case and the container are completely separate and distinct from each other.

Then, the case 102 and the container 1 are moved with respect to each other so as to define the closed condition. The relative movement of the case and the container in the closed condition allows carrying the first coupling portion 12 at the second coupling portion 13 where the two portions can be engaged with each other. The relative movement provides for the relative translation of the case 102 outside the container 1 with the lateral walls 104 of the case 102 strictly facing the lateral walls 4 of the container 1. The relative movement provides for the relative translation of the case 102 with respect to the container 1 up to an end stop position in which the top wall 109 of the case 102 is abutted against the free edge 6 of the container 1 (figure 6); in the end stop position, the free edge 106 of the case 102 is arranged at the bottom wall 9 of the container 1. In the end stop position the free edge 6 of the container is abutted against the top wall 109 of the case 102 and prevents a further relative moving closer between the bottom wall 9 of the container 1 and the top wall of the case 102. In the end stop position, the first and second coupling portions 12, 13 are configured for being engaged with each other so as to define the locking condition of the safety device 11 .

With relative movement of the case with respect to the container, it is intended the movement of both parts, i.e. the case and the container, or the movement of only one of said parts (only the case 102 or only the container), maintaining stopped the other of the two parts (maintaining fixed the case 102 or the container) in a manner such that a relative motion is defined (the case and the container) between these.

Method for opening the package 100

Also forming the object of the present invention is a method for opening a package 100 in accordance with one or more of the enclosed claims and/or in accordance with the above-reported description. Before the execution of the method for opening the package 100, the latter is situated in the locking condition of the safety device.

The opening method comprises a step of moving the at least one selector 90 (optionally of the first and of the second selector 90a, 90b), in the locking condition and from outside the package 100, from the second to the first operative position so as to define the through opening on the lateral wall of the case 102. Due to the definition of the through opening, the user can contact (manually or by means of a suitable opening device), from outside the package 100, at least one between the first and second coupling portions 12, 13 in order to allow the disengagement. For example, the step of contacting at least one between the first and second coupling portions 12, 13 comprises at least one between the following sub-steps:

- inserting at least one opening device through the through passage of the wall 60,

- manually and directly contacting at least one between the first and second coupling portions 12, 13, for example by means of insertion of a user's finger through the through passage of the wall 60,

- thrustingly act on at least one between the first and second coupling portions so as to distance them and hence disengage them.

The disengagement step comprises the thrust of the second portion of the container 1 in moving closer to the compartment 3, optionally by means of a manual intervention of a user (directly on the second portion 13 or indirectly by means of the elastic deformation of the thrust portion) or by means of an opening device. Following the disengagement of the first and second coupling portion 12, 13, the opening method provides for a relative movement step, moving away the container 1 and the case 102 (condition illustrated in figures 8 and 10) until the open condition of the case 102 is reached. The relative movement can be obtained by moving both the container and the case or it can be executed by maintained stopped one between said container and case and by moving only the other between said container and case.

Of course, if there is a first and a second coupling portion 12, 13 disengageable by means of the unlocking portion, the user, in order to allow the opening of the package 100, must disengage all the first and second coupling portions 12, 13 present on the package through the unlocking portion 17 and through the through opening definable by the selector on the wall 60.
