Definitions
- the present invention relates to a bag for packaging or packaging a load of one or more products, capable for example of flowing by gravity, whether it is a particulate solid product, for example a powder, or whether it is a single object or multiple objects in bulk.
- the invention relates to bags generally comprising an envelope closed on one side by a bottom, and delimiting on the other side a mouth allowing when it is open the passage or crossing of the load, s 'flowing for example by gravity in the inverted position of said bag.
- the envelope is shaped on itself, in particular folded, at the level of the mouth to close this bag.
- This conformation obtained by folding or folding the envelope over itself, comprises: - an outer sleeve, above its mouth, in the inverted position of said bag, that is to say with its mouth down;
- the envelope is shaped on itself at said mouth to close said bag.
- the envelope has a conformation, in particular folding, capable of being obtained successively by: folding towards the outside, then folding towards the inside, of the edges of the opening of the bag. , to form a upturned flap extending by an overwrap;
- FIG. 1 represents a single-use assembly, intended for example to be coupled to a device for establishing communication with an enclosure 3 fixed, this assembly comprising an inner bag according to the invention
- FIGS. 2 to 7 respectively represent the different stages of shaping the envelope of the bag, filled with a filler (not shown), to result in the conformation represented in FIG. 1.
- a single-use assembly has been shown, intended to be coupled with a device for placing in communication with a fixed enclosure, for example a clean or sterile room.
- This set generally includes:
- an outer bag 10 which can be under partial vacuum, having a flexible wall;
- a member 11 for closing the outer bag 10, comprising, not shown, a removable door element with a seal;
- the bag 1 comprises an envelope 2 closed on one side by a bottom 3, and delimiting on the other side a mouth 4, closed thanks to the conformation of 1 • envelope 2 described below, at this mouth.
- this conformation determines, without discontinuity of material or wall, but also without sheet or other attached wall:
- the parallel edges 2d of the flap 2b are brought together and folded, according to any suitable folding, to form at least one fold 7 for interior closure of the bag.
- the parallel edges 2e of the overwrap 2c are folded to form at least one fold 9 for external closure of the bag. If necessary, the folds 7 for interior closure, and 9 for exterior closure, can be completed, to maintain their tightness, by any suitable welding, bonding, or pinching.
- the casing 2 is made of a suitable material, for example any simple or complex plastic material, intrinsically having the flexibility and the tightness required for the application considered.
- the load 12 tends to expand the bag 2 and the sleeve 6. Because of its double thickness, the latter opposes this expansion, and prohibits d 'the more the unfolding of the folds 7 under the effect of the load.
- the entire envelope 2 is unfolded, above the mouth 4, without practicing opening at the latter, for example by cutting or tearing, and therefore without being liable to contaminate the interior of the bag 1, due to the opening manipulation of the latter.
