Definitions
- the invention relates to a gusseted bag made of flexible, multilayer film, the inner layer of which can be welded, in an embodiment in accordance with the preamble of claim 1.
- the side gusset halves are connected on the outside along the upper edge edges in order to bring about a seal which is additionally improved by folding over the end regions and fixing the folded end regions on the adjacent side gusset half.
- the invention addresses the problem of further improving the sealing of the gussets at their upper ends.
- the invention solves this problem by a gusseted bag with the features of claim 1.
- FIG. 1 is a broken view of the upper end portion of a bag according to the invention
- FIG. 3 is a view similar to FIG. 1 of a modified bag design
- Fig. 4 is a section along the line IV-IV in Fig. 3, and
- FIG. 5 is a sectional view similar to FIG. 4 with the reclosure device open at the head end of the bag.
- the gusseted bags shown in the drawing consist of a flexible, multilayer, at least two-layer film made of preferably thermoplastic material.
- the inner layer of the film is weldable and consists, for example, of a polyolefin such as polyethylene or polypropylene.
- a metal foil e.g. Aluminum foil and / or a polyester layer can be formed, which in turn is not weldable, but offers high strength and good printability.
- the bags shown have a front wall 1 and a congruent rear wall 2 and side folds 3, 4 inserted between them, which extend from the bottom end (not shown) to the top end of the bag and end at a distance below the upper edge 5 of the bag walls 1, 2.
- the bag walls 1, 2 are welded to one another along their marginal edges with the side folds 3, 4 and in the head region of the bag free of side folds, namely by means of longitudinal weld seams 6, 7 on the edge.
- the bottom end is also covered by a Cross weld seam (not shown) closed, which can be done before or after filling the bag with filling material.
- a closure device In the area of the head end of the bag, a closure device is usually provided, which can be formed by a weld seam, which is attached before or after filling the bag with filling material. It can also consist of a reclosing device which, in the embodiment according to FIGS. 1 and 2, is formed by snap fastener tapes in the manner of tongue and groove.
- this reclosing device 8 consists of two closure straps 9, 10, which extend across the bag width, one of which is attached to the bag front wall 1 and the other to the bag rear wall 2 by welding or heat sealing.
- the fastener tapes 9, 10 carry locking members 11, which can be converted into mutual engagement by pressure and release themselves from their mutual engagement with a corresponding train.
- the upper end region 12 of both side gussets 3, 4 is folded over along an inward and obliquely downward folding edge 13, the folding being able to be directed toward the front bag wall 1 or towards the rear bag wall 2.
- the folded end regions 12 of the side folds 3, 4 have the shape of a right-angled triangle and are connected to the half of the side folds 3, 4 facing them by welding, as is illustrated in FIGS. 2, 4 and 5 by the schematically represented weld seam 14 , Furthermore, the folded-over end regions 12 are welded on their outside to the adjacent bag wall, in the exemplary embodiments shown to the bag rear wall 2, as is illustrated by the weld seam 15, which is also shown schematically in FIGS. 2, 4 and 5.
- a region 16 of the equilateral side gusset halves adjacent to the folded end regions 12 of the side folds 3, 4 is welded to the adjacent bag wall 2 so that the welded connection regions enclose the upper edge edges 17 of the folded end regions 12. This ensures that the upper ends of the side gussets 3, 4 are absolutely sealed, regardless of whether the superimposed outer surfaces of the side gussets 3, 4 along the upper edge 17 are additionally provided with a closure, for example an adhesive closure, or Not.
- a reclosure device 18 is provided in the head region of the bag, which is designed as a three-layer sealing strip which extends over the entire width of the bag.
- the two outer layers 19, 20 are each welded to the inside of the adjacent bag wall 1 or 2, as is symbolized by the welded connections 21, 22.
- the middle layer 23 consists of a durable or adhesive material based on synthetic resin or plastic, which can be separated into two sub-layers by cohesive failure when a tensile force is exerted on the middle layer 23 by pulling the bag walls 1, 2 apart. After removal of material, the two separate sub-layers can be joined together again by pressing them together to form a closed middle layer 23. Otherwise, the embodiment according to FIGS. 3 to 5 corresponds to the bag embodiment according to FIGS. 1 and 2.
