Definitions

  • the present invention relates to a packaging produced from a pleated film and capable of packaging in particular bulk products such as fries, but not exclusively.
  • Patent FR-A-2595666 claims the packaging of a convex body using a thin pleated sheet, the folds of which are fixed at their ends.
  • Patent FR-A-2628719 claims several methods of fixing said folds.
  • Patent FR-A-2676037 describes a packaging made of paper, one part of which is pleated and capable of unfolding and the other non-pleated part consisting of the same sheet or of a different sheet fixed to the end of the pleated part. .
  • This packaging is intended to package a convex object of relatively stable shape. None of this packaging allows, in return, to pack a set of non-coherent objects since they do not have a stable shape, because it is impossible to deploy the packaging around.
  • Patent FR-A-2681582 proposes a solution to this problem by associating a cardboard receptacle with a sheet of pleated paper capable of unfolding; the products are introduced into the cardboard receptacle, then the sheet of paper is deployed using the cardboard receptacle as a support having a convex shape; this solution which makes it possible to obtain a relatively aesthetic packaging is expensive since it uses cardboard; However, it has the drawback of associating a rigid sheet of complex shape and a pleated flexible sheet which creates risks of tearing at the connection of the two types of sheets during handling.
  • the object of the invention is to provide packaging, in particular for bulk products, which is only designed from thin films, and which avoids the aforementioned drawbacks.
  • This object is achieved by the packaging according to claim 1, the preamble of which is based on the state of the art according to FR-A-2 676 037.
  • Fig.1 shows a package according to the invention not deployed.
  • Fig.2 shows a package according to the invention not deployed and provided with a bellows-shaped bottom.
  • Fig.3 shows a package according to Fig.1 deployed.
  • Fig.4 shows a package according to Fig.2 deployed in a configuration where the shape of the folds allows to create a receptacle.
  • Fig.5 shows a variant of the packaging according to the invention comprising a non-pleated part closed at its end.
  • Fig.6 shows the packaging of Fig.5 deployed.
  • Fig.7 shows a package according to the variant shown in Fig.5, the non-pleated part is fixed on the one hand at its end and on the other hand to the connection with the pleated part to form a bag.
  • Fig.8 shows a package according to the variant shown in Fig.5 whose pleated part is replaced by a pleated part whose folds are blocked so that they cannot deploy.
  • the FiG.9 represents the packaging of Fig.8 when it is closed by the deployment of the pleated part.
  • Fig.10 shows a package according to the variant shown in Fig.8 whose folds are not blocked and which can be deployed before closing by deployment of the pleated part.
  • Fig.11 shows the packaging according to Fig.10 when it is fully deployed.
  • Fig.12 shows the packaging of Fig.6 after turning and opening.
  • Fig; 13 shows a bag with offset edges according to the invention.
  • Fig.14 shows a film whose edge has a hem made before pleating the film.
  • Fig. 15 shows the previous pleated film with indication of the pleat fixing zones.
  • Fig.16 shows a bag whose folds have been undone to widen the opening.
  • Fig. 17 shows a bag according to the invention containing a sandwich.
  • Fig.18 shows the bag containing the sandwich according to Fig.17 closed by a flap.
  • Fig. 19 shows the bag according to Fig. 17 whose folds have been removed to widen the opening.
  • Fig. 20 shows a section of the pleated area according to Fig. 15 located below the hem.
  • a pleated packaging is produced from a thin sheet according to one of the patents FR-A-2595666 and FR-A-2676037; the pleating is in a substantially planar and rectangular shape; the packaging is folded back on itself (fig.1) so that the fold 1 or folds 2 (fig.2) which result therefrom are perpendicular to the folds 3 (fig.1) constituting the packaging; then, the side edges 4 and 5 are fixed together by means suitable for the composition of the thin sheet in order to form a sachet; it is possible, by appropriate folding, to make a bellows 6 at the bottom of this bag (fig. 2) so as to give more space in the bottom of the bag.
  • This sachet (fig.1 or fig.2) can be used advantageously in fast food as a replacement for the traditional fries cone; it is designed for example from a complex formed of paper and polyethylene in a thin layer, fixing the folds 3 at their ends 7 and side edges 4 and 5 is made by welding; the bag as described can be filled with fries like a cardboard cone; the sachet, like the cornet, serves as a dispenser for the quantity of fries delivered; the operator's hand is protected during operation by several thicknesses of paper resulting from the initial folding, making it possible to obtain the folds 3; one can conceive the folding so that there is at least 3 thicknesses of paper by choosing the ratio between the short side of the fold and its large side, as defined in the patents cited in reference, in an appropriate manner; for a ratio greater than 2, there is an alternation of zone comprising three thicknesses and zones comprising only one thickness, while for a value less than 2, there are at least three thicknesses of paper.
  • the sachet (fig.1) is filled with its quantity of fries, it is possible, by spreading the base 8 by pulling on the corners 9, to unfold the folds 3; the volume of the sachet increases (fig.3) and the fries thus fall into a cavity which protects them from cooling, while keeping the initial opening 10 which then serves as ventilation and which tends to close partially like lips; the deployed bag, thus formed, can be placed on a tray and keep a stable position there; depending on the height 29 of the bag, the deployment rate as a function of the shape of the folds (fig. 3 and fig.
  • the profile of the deployed pouch (fig. 3) resembles a sector of circular ring, formed of two concentric arcs of a circle, limited by radii, formed by the lateral weld lines 4 and 5, forming an angle between them 11 less than 180 °; if the pouch is turned over, the fries have the possibility of being guided preferably towards the opening of the bag, especially if the angle is small; if the ratio of the sides of the folds is small, for example of the order of 1.5 (FIG.
  • the angle 11 of the spokes, formed by the lateral welds 4 and 5 is greater than 180 °; the bag formed has kinds of horns in which the fries can be housed when the bag is turned over and thus they cannot fall through the opening 10 which is then located above the product. All this does not prevent the consumer from passing his fingers through the opening of the deployed sachet (fig. 3 and fig. 4) to pick up the fries in order to eat them.
  • the wall 33 of the bag corresponding to the longest edge 32 serves as a guide to separate the other wall 31 and thus open the bag.
  • an offset 36 is chosen between the two edges 31 and 32, preferably greater than the height 37 of the hem 35; the hem 35 of the most set back edge 32 comes into contact with a polyethylene coated wall 33, when the side edges 4 and 5 of the bag are welded 40, and can therefore be fixed on the other face 33.
  • the offset 36 between the two edges 31 and 32 can be voluntarily increased so that one of the two walls 41 (fig.17) can constitute a flap allowing the bag to be closed (fig.18) thus produced acting as one closes an envelope. It can be seen that in the bag thus produced, the presence of the folds means that at least one part 42 (fig. 20) of the surface of the bag has at least three thicknesses of paper 43,44,45 and constitutes, in these areas, a more effective insulation against heat loss.
  • the hem 46 (fig.14) is made by positioning the plastic inside the fold and the hem 46 is welded at 50; to fix the ideas, the hem 46 is, for example, located between 5 and 10 mm in width for a package intended to contain about 150 g of fries; then the pleating is carried out (fig. 15) and the pleats are fixed in the area 51 which adjoins the hem 46 by direct heating of the paper so that the walls 52 and 53 (fig.
  • FIG. 6 Another way to create a receptacle is from a pleated packaging of the type described in patent application FR-A-2676037 in which the pleated part 13 is extended by an unpleated part 14 allowing to wrap for example a sandwich made from a semi-rigid pancake folded in half; this package is folded back on itself, optionally making a bellows as before and only the end 15 of the non-pleated part is fixed; the product is arranged in the non-pleated part 14 so as to fill it as well as possible and thus constitute, in cooperation with the latter, a coherent assembly which can then be closed (fig. 6) by the deployment of the pleated part 13.
