Definitions
- the invention relates to the technical sector of plastic packaging bags, for example of the type intended for receiving animal feed.
- these types of bags may have on their side edges bellows able to increase the capacity of the bag and improve the stability of the latter.
- the bellows are made on the entire height of the bag.
- the bags can be made continuously from a single plastic film.
- the film is subjected to successive bending operations to achieve the lateral bellows between two walls.
- the external folds of the bellows thus produced are generally assembled by welding operations.
- the bottom of the bag is also made continuously by welding, then folded down and attached to one of the walls of the bag.
- the bellows are made by successive bends over the entire height of the bag. It therefore appears, at level of the opening of the bag, that the ends of said opening are delimited by four walls resulting from the cross section of the bellows.
- the bag is not formed from a single plastic film subjected to successive folding operations to achieve the bellows, but from two independent films whose walls are joined by means of bellows reported independents. It is obvious that with this solution, it is conceivable to produce bags with bellows lower than the total height of the desired bag, since such bellows are made independently. It is conceivable, however, that reporting the bellows significantly reduces production rates.
- JP 07100972 relates to a method of manufacturing bags employing specific means so as to form the bellows on only part of the height of the bag. This technical solution is expensive and does not allow to obtain high production rates.
- the object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner.
- the problem to be solved by the invention is to produce a bellows bag from a plastic film, the bellows being made by successive folds of said film, that is to say not reported, but in being of height less than the total height of the desired bag.
- This technical solution required, in particular, to solve the important problem of ensuring the tight closure of the upper end of the bellows below the free part of the walls resulting from the absence of bellows.
- the free edges of walls are assembled above the closed end at 45 ° of the bellows.
- the various assembly operations are carried out by welding.
- the bag obtained has lateral bellows on only part of its height, so as to leave, at a distance from the opening of the bag, a part of walls adapted to be assembled directly on one another, at their lateral edges, the upper end of the bellows being closed by an external folding zone at about 45 ° delimiting, a substantially triangular outer shape disposed between the two folds bellows.
- the triangular external shape can be made integral with one of the folds of the corresponding bellows.
- FIGS. 1a, 1b, 1c and 1d are purely schematic views showing the main phases of the method of producing a bag from a plastic film;
- FIG. 2 is a perspective view of the plastic bag in which the external folds of the bellows are welded to only a part of the total height of the bag at a determined distance from the opening of the bag;
- FIG. 3 is a front view of the bag after having separated the bellows as far as their assembly zone, so as to form a free portion of the bellows and a free wall part, one of which is shown folded down;
- - Figures 4, 5 and 6 are front views showing, from Figure 3, the various phases of the bag making process.
- FIG. 7 is a perspective view of the bag resulting from the process according to FIGS. 3, 4, 5 and 6;
- the bellows bag according to the invention is obtained from a plastic film (1) which is subjected to successive bending operations to achieve side gussets (la) between two walls (Ib) and (Ic). ( Figures la, Ib, Ic and Id).
- the external pleats (IaI), (Ia2) of the bellows (la) are assembled, for example up to a certain distance (a) from the opening. (the).
- the assembly of the folds (IaI) and (Ia2) of each bellows (1a) can be carried out for example by a welding operation (FIG. 2).
- the bellows (la) are separated to the level of their assembly zone so as to form a free portion of the bellows (Ia3) and a free portion of the walls (IbI), (Right here).
- this separation of the bellows (la) to the corresponding weld line (S) may result from a simple section of each of the folds (IaI), (Ia2) of each bellows.
- Each free portion of the bellows (Ia3) is then subjected to an operation capable of ensuring the upper transverse closure of the bellows from the end of the assembly line (S) of the outer pleats (IaI),
- each free portion of the bellows (Ia3) is subjected to a 45 ° twist and bend movement in excess of the lateral edges of the walls (FIG. 4).
- This 45 ° twisting and folding movement (Ia4) ensures the closure of each bellows.
- the overflowing portion resulting from said twisting and folding movements is then cut (FIG. 5).
- the free wall portion (IbI) is folded upwards in superposition of the closed end at 45 ° bellows. It is then possible to assemble the lateral edges of the two free walls (IbI), (here) by a weld line (S2) for example above the closed upper ends (Ia4) of the bellows ( Figure 6).
- the bag obtained has lateral bellows (la) on only a part of the total height of the bag, so as to leave, at a certain distance (a) from the opening of the bag, a free wall part (IbI) and (Here).
- each bellows (2a) is closed by the 45 ° internal folding zone (Ia4) delimiting a substantially triangular shape.
- This triangular shape is disposed between the two folds (IaI), (Ia2) of the corresponding bellows (la). Note that this triangular shape can be made integral (by welding for example) of one of the folds of the corresponding bellows.
- Figure 8 are drawings that shows the bag open and filled with products. In this figure, we see the end of the bellows closed according to a fold of about 45 °.
- the bag After filling in particular, the bag is closed in a sealed manner at the level of the upper horizontal edge of the free parts of walls (IbI), (Here). Also note that one of the walls (IbI) for example, can be equipped with a system of opening and closing at will of the ZIP® type, ECLAIR® closure, ...
