FIELD OF THE INVENTION

[001]. The present invention relates to a packaging comprising the composition of at least one flexible film (casing), containing attached internally, externally or between films, a section of blade/plate semi-rigid or flexible material reinforced (skeleton/soul), smaller than the perimeter flexible film (casing) that contains it, so that, when the packaging, the union formed of at least two opposite edges, semi-rigid or flexible material (skeleton/soul), tend to go back to your form original, gives the packaging a predetermined format. This is a particularly flexible, self-sustaining rolled. Such packaging offers a combination of advantages noted in flexible packaging in combination with advantages of rigid packaging, particularly on the possibility of stacking and ease of manufacturing and handling.

[002]. Further, the present invention refers to a process of preparation of the said packaging.

FUNDAMENTALS OF INVENTION

[003]. Persons skilled on the art know that there are currently different types and models of flexible packaging for bottling solid or liquid products in food, cosmetic, "pets", hygiene and cleaning fields, among others, whose forms of presentation and structure differ according to the product to bottling.

[004]. One of the major concerns of the market and that directly impacts on the cost of the final product is bottled the mechanical feature of the packaging, i.e. its capacity and storage of the product form and the possibility of embedding and transport of multiple packagings (arranging and stacking); because these products packed and boxed for shipping between the factories and distribution centers and retail centers, must traverse great distances and, thus, the structure of packagings becomes very important and affects the transport type and the volume to be carried at a charge and, therefore, the final cost of the product. [005]. Another very important aspect to be checked on the packaging is if and how can this packaging be stacked and arranged in points of sale (shelves, shelves and counters). In this sense, the format defined and Packaging mechanical structure interfere frontally in the kind of exposure that product at the points of sale.

[006]. Accordingly, to meet the needs of stacking, emerged on the market the self portable packaging (self-sustaining) compiled on the basis of cardboard paper, owned by the Tetrapak ®. This packaging allows the filling only in specific lines of your manufacturer, which is a limiting aspect to other packaging industries.

[007]. This solution of the Tetrapak ® presents the features while filling the packaging form {Form Fill Seal), however, due to the different composition materials, does not allow recycling or composting of packaging when discarded.

[008]. Another aspect of this solution of disadvantageous Tetrapak ® is that it doesn't allow packaging of solids or powders and that it only allows stacking if you don't have a lid or curvature at the top (example: old carton of milk long life). And, finally, your structural design allows only small variations in your design, resulting in a few packaging formats, even for customers and/or different brand products.

[009]. Further, it should be mentioned the packaging of type bag stand up pouch "which are self portable, i.e., self-sustaining, but have the disadvantage that almost every filling machines; in your vast majority Form Fill Seal (FFS), not allow or accept such constructiveness. So, there is no filling of the product while the packaging (FFS), forcing the bottling of the product after Packaging formation, setting up separate operating two steps.

[0010]. In addition to the inconvenience of filling not concomitant with the formation of the packaging bag type {stand-up pouch), this won't admit to stacking, is for transport, be it for exhibition in gondola or shelf at the point of retail. And finally, its conformation aesthetics hardly admit variation in your format.

[0011]. It is noteworthy that even among the entire universe of packaging possible and known, there are those plastic and flexible packaging produced and understood by a combination of different laminate substrates that are used to aggregate value to them, is to contribute on the aesthetic issues, as it allows the quality and print protection labelling of products, is to increase the barrier properties and reduce costs. One of the characteristics of laminated packaging is the union of two or more flexible films that, according to their properties, will provide the necessary requirements for packaging, the packaging and protection, productivity and transportation and product display in the shelves.

[0012]. Another feature of the laminates is the possibility of several materials of different properties on a single laminar structure, diversifying the possibilities of application, according to the product being bottled; besides being extremely economical with regard to the relationship of quantity of material used in packaging for quantity of packed product.

[0013]. However, despite all the advantages of diversification possibility checked on packagings, rolled a big disadvantage when it comes to your mechanical and structural resistance (format) because, due to your flexibility all structural products bottled in laminated packaging are limited to be exposed in a single level without stacking, because packaging adopts structural format your content.

[0014]. This type of laminated packaging has some options of the form (e.g., flat bottom pad, "false stand up pouch", false welds), but all depend on the internal content to set final form of presentation to consumers; and does not allow stacking, as already mentioned.

[0015]. We highlight below some of the teachings of the prior art referred to in this matter:

[0016]. The patent document BR 10 2013 027062 8 describes a packaging for fragile foods comprising a plastic hard tray cased with a thermo-sealable flexible plastic bag, the tray comprising dividers and plastic bag comprising a carrying strap.

[0017]. Other patent documents as EP 2 374 725 and US 5,123,527 also refer to trays made of hard material by flexible film. [0018]. Furthermore, the document BR 1 104357-1 reveals a conditioning and transporting packaging of chemical products composed of two integrated parts, namely, a flexible bag wrap and inner drive, and said the bag is waterproof made of plastic with opening.

[0019]. Other patent documents as BR 9813081 -1 , BR 0713108-9 and US 2017/1 13236 describe packaging also composed a bag or receptacle and flexible internal hard wrap.

[0020]. Moreover, the documents of patent BR 0804308-6, US 2017/1 13236, US 8,151 ,992, WO 2016/120550, US 2012/0106877, US 3,249,286 and US 5,205,651 refer to rigid packaging or packagings made of flexible material, or start from a rigid packaging involve it with flexible film.

[0021]. Therefore, does not exist in the state of the art solution equivalent to the presented here in this invention that combines technical differentiators, economic advantages with production in scale, at low cost and industrial applicability and safety allies reliability.

DETAILED DESCRIPTION OF THE INVENTION

[0070]. The present invention refers to a flexible laminated packaging and self- sustainable. The present invention relates to a packaging comprising the composition of at least one flexible film (casing), containing attached internally, externally or between films a semi-rigid material blade section or flexible film reinforced (skeleton/soul) smaller than the perimeter of the enclosure. This is a packaging that includes a structure formed from a skeleton/soul semi-rigid material or reinforced flexible film comprising at least one blade with predetermined format attached to a casing of flexible material that protects the said skeleton/soul, preferably with the perimeter of the enclosure dimensions larger than the dimensions perimeter of the skeleton/soul.

[0071]. The object of the present invention comprises packaging:

[0072]. -a structure (skeleton/soul) (1 ) comprising at least one blade (4) semirigid material or reinforced flexible film showing predetermined format,

[0073]. -casing (2) formed from a flexible material, preferably at least one flexible film;

[0074]. Being that the casing (2) features perimeter dimensions larger than the dimensions of the perimeter structure (skeleton/soul) (1 ); [0075]. When the packaging is mounted with the union of at least two opposite edges.

[0076]. Semi-rigid material means those who have an average modulus and elongation under pressure disappears completely when the pressure is removed tending to return to your original format as for example a sheet of PVC.

[0077]. Further, the semi-rigid material or reinforced flexible film can be transparent, translucent, opaque. Besides, it can be colorless or colored and also texture.

[0078]. The term flexible film is usually used to describe a thin plastic material usually not more than 75 microns (0.003 inch) thick. Examples of flexible films that can be used for preparation of the casing are: PP (polypropylene) films, films of PE (polyethylene), bioplastics and many others which form such as bags of snacks. Notwithstanding, and not limited to plastic films, are already developing cellulosic films today or even specialty papers that can be used in the future in this process.

[0079]. Further, the film can be transparent, translucent flexible and/or opaque. Besides, it can be colorless or colored and also texture. It may contain impressions in one of their surfaces with say about the product packaged in the packaging object of the present invention.

[0080]. The skeleton/soul (1 ) can present various formats such as but not limited to: square, rectangle, rhombus, triangle, among others. Further, the skeleton/soul (1 ) in alternative achievements can be hollowed, corrugated, cross-linked, present relief, crease (5), among other possibilities or other characteristics of the order or providing material saving textures and shapes.

[0081]. In a first preferred embodiment of the present invention, illustrated in figures 1 to 4, the packaging object of the present invention comprises a structure (skeleton/soul) (1 ) formed from a flat/plane blade (4) of a material semi-rigid applied to a casing (2). The position of these two parts of the packaging object of the present invention can vary as can be seen from Figures 2 and 4. Further, the packaging can comprise two casings (2) involving the structure or skeleton/soul (1 ) on both sides as can be seen from Figure 3. [0082]. Based on this preferred embodiment, it is possible to prepare the packaging with circular cross section forming a cylindrical-shaped packaging as shown in Figure 5.

[0083]. With this same logic, it is possible to prepare packaging with elliptical cross-section, for example (not illustrated in figures). Further, cross sections may have different dimensions in packaging formed, resulting in a conical shaped packaging or even log-taper.

[0084]. You can see from the figures 16 to 25, that the flat/plane blades (4) may be the most different formats causing changes in the skeleton/soul (1 ). With these alternatives, reach different packaging formats for different uses. Figures 16 to 25 feature favorite examples applied to the first achievement illustrated in figures 1 favorite to 5. However, these options can be applied in other favorite achievements and also in other formats mentioned here can be applied on the packaging object of the present invention. See if the following options:

[0085]. -The Figure 16 comprises blades (4) of the skeleton/soul (1 ) in a rectangular shape being flat and solid, similar to that illustrated in Figure 1 ;

[0086]. -The Figure 17 comprises blades (4) of the skeleton/soul (1 ) in square format aimed at economy of material;

[0087]. -The Figure 18 comprises blades (4) of the skeleton/soul (1 ) in another rectangular shape also aimed at economy of material;

[0088]. -The Figure 19 comprises blades (4) of the skeleton/soul (1 ) cross- shaped also aimed at economy of material;

[0089]. -The Figure 20 comprises blades (4) of the skeleton/soul (1 ) oval-shaped also aimed at economy of material;

[0090]. -The Figure 21 comprises blades (4) of the skeleton/soul (1 ) "H"-shaped also aimed at economy of material;

[0091]. -The Figure 22 comprises blades (4) of the skeleton/soul (1 ) hollowed rectangular format also aimed at saving material; [0092]. -The Figure 23 comprises blades (4) of the skeleton/soul (1 ) in another hollowed rectangular format also aimed at saving material;

[0093]. -The Figure 24 comprises blades (4) of the skeleton/soul (1 ) in another rectangular shape with texture also aimed at economy of material;

[0094]. -The Figure 25 comprises blades (4) of the skeleton/soul (1 ) in rectangular shape with creases (5) providing different formats for packaging of the present invention;

[0095]. -The Figure 26 comprises blades (4) of the skeleton/soul (1 ) in rectangular format containing spaces in your configuration.

[0096]. In a second preferred embodiment of the present invention, illustrated in figures 6 to 10, the packaging object of the present invention comprises an internal structure or skeleton/soul (1 ) formed from a plurality of blades flat and plane (4) of semi-rigid material or reinforced film and at least a casing (2) formed from flexible film. As can be seen from Figure 6, the blades (4) skeleton/soul (1 ) that form the structure (1 ) are positioned so adjacent to each other and their total area must be less than the area of the casing (2).

[0097]. The position of these two parts of the packaging object of the present invention can vary as can be seen from Figures 7 and 9. Further, the packaging can comprise two casings (2) involving the skeleton/soul (1 ) on both sides as can be seen from the Figure 8.

[0098]. Based on this preferred embodiment, it is possible to prepare the casing with quadrangular cross-section forming a parallelepiped-shaped packaging as shown in Figure 10 with the composition shown in any of the 6 Figures 9 and the packaging with the folding spans formed between the blades (4) of the skeleton/soul (1 ) tiled.

[0099]. With this same logic, it is possible to prepare packaging with rectangular cross-section or diamond or even format format of polygons with 3 sides or more, for example (not illustrated in figures). The amount of sides determined in packaging cross-section will be by the number of blades (4) positioned side by side forming the skeleton/soul (1 ). Further, cross sections may have different dimensions in packaging formed, resulting in a pyramidal or prismatic shape or even trunk-trunk-prismatic or pyramidal.

[00100]. In a third preferred embodiment of the present invention, illustrated in figures 1 1 to 15, the packaging object of the present invention comprises an internal structure or skeleton/soul (1 ) formed from a flat/plane blade (4) stiffer, or of reinforced film, with creases (5) spaced and arranged in vertical direction from the packaging to be set and at least one casing (2) formed from flexible film. As can be seen from Figure 1 1 , the flat/plane blade (4) that forms the skeleton/soul (1 ) is placed on the casing (2) having creases (5) arranged over the whole blade (4) of the skeleton/soul (1 ).

[00101]. The position of these two parts of the packaging object of the present invention can vary as can be seen from the Figures 12 and 14. Further, the packaging can comprise two casings (2) involving the internal structure- skeleton/soul (1 ) on both sides as can be seen from the Figure 13.

[00102]. Based on this preferred embodiment, it is possible to prepare the casing with quadrangular cross-section forming a pack in box format as illustrated in Figure 15 with lock the composition shown in any of the Figures 1 1 to 14 and the packaging with the folding creases (5) present in the blade (4) of the skeleton/soul

(1 )-

[00103]. With this same logic, it is possible to prepare the packaging with rectangular cross-section or diamond format or format of polygons with 3 sides or more, for example (not illustrated in figures). The amount of sides determined in cross section of the packaging will be the amount of creases (5) present in the flat/plane blade (4) forming the skeleton/soul (1 ). Further, cross sections may have different dimensions in packaging formed, resulting in a pyramidal or prismatic shape or even trunk-prismatic or trunk-pyramidal.

[00104]. In any one of the favorite achievements presented here or any other can be prepared from the packaging object of the present invention using currently known means to attach skeleton/soul (1 ), for example: solder, glue, tape, by interference between other fixings. [00105]. The resulting packaging object of the present invention can be added and incremented receiving applications in different technologies like, for example, as material for the casing (2) a film-oriented polypropylene film, it is possible to provide opening the packaging for tear oriented or even through a ribbon positioned to open the packaging. Further, if you can apply zip resealable technologies like zipper, open-close labels, caps, among others.

[00106]. The packaging object of the present invention is prepared from the process comprises the following steps:

[00107]. -Selecting material for preparation of at least one blade (4) that will form the structure/skeleton/soul (1 );

[00108]. -Selecting material for preparation of the casing (2);

[00109]. -Positioning at least one blade (4) to form the structure (skeleton/soul) (1 ) in the casing (2) by overlapping;

[00110]. -Preparing the packaging with desired format having the casing (2) containing attached itself the skeleton/soul (1 );

[00111 ]. - Promoting packaging closing with the union of two opposite edges.

[00112]. Such edges, when joined together, are parallel to the longitudinal axis of the packaging object from the invention. Further, the internal structure, the skeleton/soul (1 ), can comprise that edges are the sides perpendicular to edges (3) and that can also be joined together when folding the skeleton/soul (1 ) in order to close it fully.

[00113]. A realization of this favorite invention can be used in filling equipment of type Vertical and Horizontal Form Fill Seal and e Flow Pack (where the packaging is formed at the same time as the product is packed), allowing a quick and cheaper way to make an auto sustainable packaging with a high productivity with low cost and wide variety of formats and to keep the barrier characteristics and practicality of laminate film, which allows the end, a differentiated and specific design , with the possibility of stacking, in addition to increasing the physical protection to the product. [00114]. In this case, the packaging of the present invention obtained Form Fill Seal process (where the packaging is formed at the same time as the product is packed) and, more specifically, to a design of laminated composite structure and flexible to be used in the formation of self-sustaining and packaging likely stable stacking.

[00115]. The present invention presents numerous technical and economic advantages when compared with the state of the art, being a few listed below:

[00116]. -the packaging of this invention is self-sustaining and in a single composition;

[00117]. - is produced with low cost;

[00118]. -allows your recycling after use or even reuse;
