Definitions

  • the present invention relates to flexible packaging, made for example of a plastic material, and forming sachets intended to protect their content from external conditions, such as ambient humidity or dust, or to prevent their content from being handled before the purchase of the object thus packaged.
  • ties such as textile cords.
  • These links are trapped, during the manufacture of the packaging, in folds of the plastic film constituting the packaging, these folds then being welded on either side of the link to provide them with a passage. , and so that at least one end of each link is accessible from the outside of the package. A line of least resistance is then produced between the edge of the packaging, itself welded, and the welding of the link passage closest to this edge.
  • the advantage of such an arrangement lies in the fact that it is then possible to suspend or hang the package thus closed in a place close to the place of use of the contents of the package, so as to ensure the availability of its content at its place of use. It suffices, in fact, to unhook the packaging, possibly to untie the links, to unfold the upper part of the packaging to have access to its content, to take a part of it, to close the packaging by pulling on the links, possibly to re-tie them, and to suspend the closed packaging again.
  • this last line can be made in the upper and / or lower part of the packaging in the suspended position, depending on the nature of the content of the packaging.
  • the presence of the links constitutes a drawback, since, on the one hand, they no longer have the function of opening / closing the packaging, but only that of suspending the packaging, and that, on the other hand, the laying of these links during the manufacture of the packaging is an expensive operation, by the intrinsic cost of the link itself and by the notable slowdown in production induced by the laying of the links, compared to the production of identical packaging without links.
  • recycling of packaging fitted with links is substantially impossible: the sachet must, in fact, be destroyed, for example by incineration.
  • Document FR-A-2 678 908 also discloses a resealable packaging intended to contain, with a view to their exposure for sale, articles of small dimensions, comprising a sachet of transparent plastic material secured to an information card.
  • the information card consists of a jumper, the two flaps of which enclose the upper part of the bag, one edge of the opening of which is welded by its external face to a jumper flap, the other edge being welded bilaterally, on a small width, to the other flap, which comprises two pre-cuts arranged at a certain distance from the edges of the flap and extending over a height slightly greater than that of the part of the bag enclosed by the two flaps of the rider.
  • This packaging also has the same drawbacks, due to the combination of the packaging with a cardboard jumper, constituting an informative card, slowing the manufacture of the packaging, increasing its cost and making recycling operations for used packaging difficult.
  • the present invention is placed in this context and aims to provide a packaging that can be suspended, which does not require links or foreign materials to the packaging material, the latter must also be simple, reliable and inexpensive to manufacture. expensive.
  • the subject of the present invention is a package comprising a folded sheet and having two faces on either side of a bottom fold, the two faces being joined by their lateral edges adjacent to the bottom fold and by a transverse line substantially parallel to the edges of the faces opposite the bottom fold and at a predetermined distance from these edges.
  • At least one line of least resistance is formed from at least one of the lateral edges, at a distance from the edges of the faces less than the predetermined distance, and over a length less than the width of the packaging. , so as to form a zone over the width of which the packaging is devoid of lines of least resistance.
  • the part of the packaging located between the line of least resistance and the edges of the faces opposite to the bottom fold is capable of forming, after breaking the line of least resistance, a hooking loop of the packaging.
  • a hole is formed at the end of the line of least resistance distant from the lateral edge.
  • flaps can be formed at the edges of the faces by folding the ends of the sheet constituting the packaging to a height greater than the predetermined distance, and the bottom fold can consist of a triple bottom fold to form a bottom gusset.
  • the line of least resistance is a line of spaced and precut dashes, alternated with tenons not cut.
  • Such packaging can, moreover, comprise at least one second line of least resistance at a distance from the edges of the faces greater than the predetermined distance, an adhesive tab can then be secured to the face of one side of the second line of least resistance, and intended to cooperate with the part of the face situated on the other side of the second line of least resistance.
  • the invention also relates to a device for manufacturing this packaging.
  • This device consists of a rotary precut tool intended for precutting a line of least resistance, said tool comprising a first cylindrical rotary member of circumference, for example, but not necessarily, equal to the width of the packaging, and a second rotary member bearing a series of teeth regularly spaced apart and formed with a portion devoid of teeth, and extending over an arc of a length equal to the width of the zone of the packaging devoid of line of least resistance.
  • a packaging bag designated as a whole by the reference 10, formed of a film or a sheet of plastic material, such as polyethylene or polypropylene, folded on itself so as to present two faces 12 and 14 on either side of a bottom fold 16.
  • One of the faces, the face 12 in the example shown, has a line of least resistance 18, for example rectilinear and parallel to the bottom fold 16.
  • Line 18 can be obtained by precut spaced dashes, leaving between them uncut parts, also called "studs".
  • an adhesive tab 20 integral with the face 12 on one side of the line 18, and intended to cooperate with the part of the face 12 situated on the other side of this line 18.
  • the two faces 12 and 14 are intended to be welded by their lateral edges 22 and 24 adjacent to the bottom fold 16 so as to form a pocket into which the object or objects to be packaged can be introduced, through the opening 26.
  • the two faces 12 and 14 can then be welded transversely along a line 28, substantially parallel to the edges 30 of the faces 12 and 14 opposite the bottom fold 16, and at a predetermined distance D from these edges.
  • the package 10 comprises a line of least resistance 32, substantially parallel to the edges 30 of the faces 12 and 14, and at a predetermined distance d from these edges.
  • Line 32 is formed from one of the lateral edges of the packaging, for example the edge 22, and over only part of the width L of the packaging, so as to provide an area 34, of width I , devoid of line of least resistance.
  • Line 32 can advantageously be obtained, like line 18, by a precut of spaced dashes, leaving between them uncut parts, or tenons. Line 32 can thus be obtained from an alternative precut tool, cutting the dashes one after the other.
  • a rotary precut tool shown in FIG. 5, will be used.
  • This tool comprises a cylindrical roller 36, having an external surface 38.
  • the tool also comprises a wheel 40, partially toothed, driven at the same tangential speed of rotation as that of the roller 36 in the opposite direction, as shown by arrows A and B in Figure 5, by means of toothed belts or pinions (not shown).
  • the wheel 40 comprises a series of teeth 42, regularly spaced, and cutting, intended to form, in cooperation with the outer surface of the roller 36 on which they successively come into contact, the dashes of the precut of the line 32.
  • the recessed parts 44 located between two successive teeth, will thus leave the studs of line 32 remain.
  • the wheel 40 further comprises a part 46, devoid of teeth, and extending over an arc of a circle length equal to width I, and intended to leave area 34 of the packaging.
  • the last dash before this area 34 be, in fact, constituted by a hole, for example circular, 33.
  • a hole for example circular, 33.
  • the wheel 40 of the precut tool so that one of its teeth 43, adjacent to the part 46 without teeth, is constituted by a cookie cutter.
  • this hole could also be made during another step, before or after the line of least resistance 32 has been made.
  • Figures 2 and 2A variants of the embodiment which has just been described can be used separately or in combination.
  • provision may be made to produce a triple bottom fold 16 ′, so as to form a bottom gusset and thus improve the presentation and / or the behavior of the packaging.
  • We can also provide a line of resistance 18 'non-straight, for example curvilinear, and made in the lower part of the package to facilitate the extraction of the contents.
  • flaps 52 By folding the ends 54 of the sheet or film constituting the faces 12 and 14 outwardly, or preferably inwards, over a height H greater than the distance D from the edge 30 ′ to which the faces 12 and 14 are intended to be welded.
  • the parts 48, 50 and the zone 34 are made up of two double thicknesses of the material constituting the packaging, thus guaranteeing a reinforcement of the loop formed using the part 50.
  • the upper part of the bag may be perforated 56, so that the latter is presented in a bundle on a spindle, for example with an automatic machine.
  • the machine welds the bag transversely along line 28 and can, if necessary, cut the upper part comprising the perforation 56 along the line 55 located between the part having the perforation 56 and the line of least resistance. 32.
  • the upper part of the bag has a flap 32
  • the dimensions d of the part intended to form the loop 50 will be chosen, and I of the zone 34 where this loop 50 is attached to the rest of the packaging, so that the device for hanging the packaging according to the invention has all the required characteristics of solidity, taking into account the forces to which this device attachment is likely to be submitted when the user takes off the adhesive tabs 20 or 20 ', and when he takes an item from the contents of the package.
  • the lines of least resistance can be obtained by means of zones of thickness less than that of the other parts of the packaging, or that the welds of the lateral edges 22 and 24 as well as the transverse line 28 may be replaced by seams, depending on the nature of the sheet or film constituting the faces 12 and 14.
