Definitions
- the present invention relates to flexible packaging, made for example in a plastic material, and forming sachets intended to protect their content from outdoor conditions, such as ambient humidity or dust, or for prevent their contents from being manipulated before purchasing the object thus packaged.
- links such as textile cords.
- These links are imprisoned, 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 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 made between the edge of the package, itself welded, and the nearest link passage welded of this edge.
- the advantage of such an arrangement lies in the fact that it is then possible to hang or hang the packaging 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. You just have to unhook the packaging, possibly untie the ties, unfold the upper part of the packaging to access its content, to take a part of it, to close the packaging by pull on the links, possibly re-tie them, and suspend again the packaging closed.
- this last line can be made at the top and / or lower of the packaging in the hanging position, depending on the nature of the contents of packaging.
- Document FR-A-2 678 908 also discloses a resealable packaging. intended to contain, with a view to their exhibition for sale, articles of small dimensions, comprising a transparent plastic bag secured to a informative card.
- the informative card is made up of a rider whose two parts enclose the upper part of the bag, one edge of the opening is welded by its external face of a jumper flap, the other edge being welded bilaterally, on a small width, to the other flap, which has two pre-cuts arranged at a some distance from the edges of the shutter 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 still has the same drawbacks, due to the association packaging with a cardboard jumper, constituting an informative card, slowing the production of packaging, increasing its cost and making it difficult to recycling operations for used packaging.
- Application WO 90/08071 describes a method for manufacturing a bag provided with a closing tape, for example a garbage bag.
- a line of low resistance is provided at a close distance from the upper edge of the bag where the opening of the bag is located, and extends over at least the three-quarters of the width of the bag.
- a strip comes off along perforations in the line of least resistance and serves as a closure tape for close the filled bag (see figure 7).
- the low resistance line is a means for form a partially detachable strip used to close an open bag.
- This request does not provide any means of hanging a full and closed bag.
- the object of the present invention is to provide a hanging packaging that does not require ties or materials foreign to the packaging material, the latter must also be manufactured simple, reliable and inexpensive.
- the present invention relates to a package comprising a folded sheet and having two sides on either side of a bottom fold, both sides being joined by their lateral edges adjacent to the bottom fold and by a line transverse substantially parallel to the edges of the faces opposite the bottom fold and a predetermined distance from these edges.
- At least one line of least resistance is formed from at least one of the side edges, at a distance from the edges of the faces below the predetermined distance, and over a length less than the width of the package, of so as to form an area over the width of which the packaging has no line of less resistance.
- the part of the packaging located between the line of least resistance and the edges of the faces opposite the bottom fold are likely to form, after breaking the line of least resistance, a loop hanging 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 in 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 bellows.
- the line of least resistance is a line of spaced and precut dashes, alternated with uncut studs.
- Such packaging may, in addition, include at least a second line of less resistance at a distance from the edges of the faces greater than the distance predetermined, 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 located 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 to precut a line of least resistance, said tool comprising a first rotary member cylindrical in circumference, for example, but not necessarily, equal to the width of the packaging, and a second rotary member carrying a series of teeth regularly spaced apart and formed with a portion devoid of teeth, and extending over an arc of circle of length equal to the width of the area of the packaging devoid of line of less resistance.
- a bag packaging designated as a whole by the reference 10, formed of a film or of a plastic sheet, such as polyethylene or polypropylene, folded over 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 lower resistance 18, for example rectilinear and parallel to the bottom fold 16.
- Line 18 can be obtained by precutting spaced dashes, leaving between them uncut parts, also called "tenons”.
- 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 in which one can introduce, through opening 26, the object or objects to be packaged.
- 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 fold bottom 16, and at a predetermined distance D from these edges.
- the package 10 includes a line of lower resistance 32, substantially parallel to the edges 30 of the faces 12 and 14, and to a predetermined distance d from these edges.
- Line 32 is formed from one of the edges sides of the packaging, for example the edge 22, and on 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 pre-cutting of spaced dashes, leaving uncut parts between them, or hold on. Line 32 can thus be obtained from a precut tool alternating, cutting the dashes one after the other.
- a rotary precut tool shown on the Figure 5.
- This tool comprises a cylindrical roller 36, having a surface outside 38.
- the tool also includes 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, using toothed belts or gables (not shown).
- the wheel 40 has a series of teeth 42, regularly spaced, and sharp, intended to form, in cooperation with the outer surface of the roller 36 on which they successively come into contact, the dashes in the precut on line 32.
- the recessed portions 44 located between two successive teeth, will thus let the tenons of line 32 remain.
- the wheel 40 further comprises a portion 46, devoid of teeth, and extending over an arc of circle of length equal to width I, and intended to leave area 34 of packaging.
- the present invention can be implemented.
- the user wishes to suspend the packaging 10, in order to have at its disposal the content of this packaging, it separates the two parts 48 and 50 of the latter located on either side of line 32 by moving away from each other. These two parts 48 and 50 are then no longer connected except by the zone 34.
- the user can then move the two edges 30 apart from one another to form a loop, which can thus be used to suspend the packaging 10, as shown in FIG. 4.
- the user then only has to break the line of least resistance 18 to take a part of the contents of the package 10, then, optionally, to close this opening using the adhesive tab 20.
- a hole for example circular, 33.
- this hole can also be made during another step, before or after completion of the line of least resistance 32.
- 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 make a triple fold of bottom 16 ', so as to form a bottom gusset and, thus, improve the presentation and / or the keeping of the packaging.
- We can also provide a line of least resistance 18 'not straight, for example curvilinear, and made in the lower part of the packaging 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, towards the outside or, preferably, towards the inside, on a height H greater than the distance D from the edge 30 'at which the faces 12 and 14 are intended to be welded.
- the parts 48, 50 and the area 34 are formed of two double thicknesses of the material making up the packaging, thus guaranteeing reinforcement of the loop formed using part 50.
- the upper part of the bag is 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, optionally cut the upper part with the perforation 56 along the line 55 located between the part with the perforation 56 and the line of least resistance 32.
- the upper part of the bag has a flap 32
- the nature and thickness of the constituent material, and / or the nature and / or the weight of its content we will choose the dimensions d of the part intended to form the loop 50, and I of the zone 34 where this loop 50 is attached to the rest of the packaging, so that the hooking device the packaging according to the invention has all the required characteristics of solidity, in taking into account the efforts to which this attachment device is likely to be submitted when the user takes off the adhesive tabs 20 or 20 ', and when he takes off part of the contents of the package.
- the invention is not limited to the embodiments which have been described, but is likely to receive numerous modifications which will appear to those skilled in the art.
- the lines of less 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, in depending on the nature of the sheet or film constituting the faces 12 and 14.
