  • the bag body 20 is defined by four main walls orthogonal to each other. Its section is thus globally square or rectangular. Two of these walls are illustrated in FIG. 1 under the references 25 and 26, The two walls additional are respectively parallel to each of these two walls 25 and 26.
  • the walls of the bag can be the subject of many embodiments.
  • thermoplastic material It is preferably walls of thermoplastic material.
  • These walls can be single or multi-layer (s) and mono or multi-material (x). If necessary, it may be a paper support coated with a layer of thermoplastic material, or a metallized thermoplastic layer.
  • the bag 20 can be made using a single sheet or several sheets, for example two sheets welded together at their edges, preferably along edges connecting the main walls, for example the edge common to walls 25 and 26.
  • a portion 30 of the bag body 20 is intended to be folded on itself in the form of a bellows.
  • the mouth 22 and the bottom 24 can both be provided with a bellows, the bag 20 therefore comprises at least one bellows.
  • this portion 30 of the bag is formed at the mouth 22.
  • the portion 30 of the bag folded in the form of a bellows has a height l1 substantially equal to twice the width l2 of the bag.
  • the above-mentioned height l1 and width l2 of the bag are considered perpendicular to the line 32 for folding the bellows.
  • the aforementioned folding operation is shown schematically by the arrow referenced P in FIG. 2.
  • the bellows obtained is referenced 50 in FIG.
  • the bellows 50 can be held open or closed by an opening / closing means itself comprising a first removable connecting element placed on the bellows and a second connecting element, the first and second connecting elements being at least partly arranged on a common element.
  • the first and second connecting elements can be fully arranged within a single and unique common element.
  • the removable connection element of the opening / closing means may be formed of a self-adhesive strip.
  • a self-adhesive strip may be provided on the end of the bag and the bellows in the form of the band referenced 42 in FIG. 2 and situated on a wall 26, or on a wall opposite to that carrying the strip 42; in the form of the band referenced 43 in FIG. 2, or else two complementary adhesive strips corresponding to the two strips 42 and 43 shown in FIG. 2. (These two strips 42 and 43 being brought into contact during the folding the bellows 50).
  • the aforementioned strips 42 and / or 43 extend parallel to the fold line 32 substantially over the entire length l3 of the bag, said length l3 being considered parallel to the fold line 32.
  • the strips 42 and / or 43 are arranged on internal faces of the bag 10.
  • the detachable connecting element may be formed of complementary elements located respectively in place of the aforementioned strips 42, 43 and shown in FIG. 2, that is to say one on the end of the wall 26 of the bag coinciding with one end of the bellows 50 and the other at the wall opposite the wall 26 of the bag body and intended to receive the end of the aforementioned bellows 50.
  • such complementary elements may be formed of complementary structures of velvet / hook type or complementary male / female profiles, or even complementary hook structures (possibly actuated by a slider).
  • all the embodiments mentioned above can be provided within a U-shaped step installed on the end of the wall 26 of the bag.
  • no band or equivalent means is necessary at the end of the wall opposite to the wall 26.
  • this band 43 or equivalent means is disposed within the U-shaped tape, opposite the band 42 or equivalent means complementary to the equivalent means of the band 43.
  • a slider 60 shown in Figure 3, may be provided at the connecting member 42, 43 removable to control its opening / closing.
  • the cursor is a means well known to those skilled in the art, so it will not be described in detail.
  • the second connecting element of the opening / closing means is preferably a band 41 forming part of the element 40. as represented in FIG. 2, this element 40 therefore consists of the assembly formed by the means 42 of the first removable connecting element 42 and / or 43 and said band 41.
  • the first and second connecting elements of the opening / closing means are therefore arranged on a common element in that the band 41 and the means 42 physically belong to the same common element 40.
  • the band 41 may consist of a paper support coated with a layer of thermoplastic material, or a metallized thermoplastic layer.
  • the dimension l4 of the band 41 is such that the detachable connecting element 42 and / or 43 is not stressed by the contents of the bag when the bellows 50 is kept folded back on itself, as shown schematically in Figure 3.
  • the band 41 forming the second connecting element and allowing the maintenance in the folded state on itself of the bellows can be subject to many variants. It may be a self-adhesive tape, complementary elements of velvet / hook type, complementary elements of the male / female type or complementary hook-type elements. In any case, this one comes fix, attach or stick at an outer zone 80 of the bag body 20.
  • the connecting member 41 provides a closure that can be opened only once in one embodiment.
  • a slider 70 controlling opening / closing of the connecting member 41 is provided. It is installed on the outer face of the connecting element 41 so that it is accessible when the bellows 50 is folded on itself, and intended to move along a line 45, extending longitudinally on the outside. element 41, and separating or joining the two parts 44 and 46 of the connecting element 41.
  • FIG. 4 shows a particular embodiment where the connecting element 41 is this time complementary to the band 43 of the first connecting element to form a common assembly 40 then disposed before the folding operation on the face of the bag body 20 located opposite the wall 26.
  • FIGS. 5a and 5b show the opening / closing means according to the preferred embodiment of the invention and shown in FIG.
  • the opening / closing means consists of two distinct physical assemblies, one formed by the means 43 and the other formed by the band 40 comprising itself. even the medium 42 and the band 41.
  • the opening / closing means consists of a U-shaped tap.
  • the complementary elements that are the means 42 and 43 and the element link 41 all belong to the same common element 40, which in this case is the U-shaped itself.
  • a portion 400, located outside this common element 40 must provide means for adhesion to the bellows.
  • the bag can not be opened without the connecting element 41 being separated in two parts by the displacement of the slider 70 (multiple openings / closures) or by the breaking of a line of weakness (single opening / closing) in place of the cursor if any.
  • the connecting element 41 thus makes it possible to fulfill a function of inviolability control at the opening of the bag.
  • FIG. 6 shows an alternative embodiment of the opening / closing means and in accordance with the embodiment shown in FIG. 4, that is to say, where the element 40 is formed by the means 43 and the band 41.
  • the connecting element 42, 43 is accessible from the outside, the U-shaped tape provides a tamper-proof function of the contents of the bag insofar as a line of weakness 410 must be broken for access the contents of the bag.
  • sliders 60 and 70 are shown on the opening / closing means and can be implemented in accordance with the description made in support of Figure 4.
  • the opening / closing means does not consist of one or more inserts on the bag body 20 but that it is a portion of the bag body 20, thereby forming an appendix of this bag.
