SIDE-GUSLIP PLASTIC FILM BAG

Description

[0001] The invention relates to a side-gusseted bag made of plastic film, in which, in a flat, empty state, at least one folding wall lies folded along a fold line between two main walls, forming a double layer. The side-gusseted bag has a carrying handle arranged on the inside of the folding wall and having at least two handle straps. The handle straps are arranged on either side of the fold line and are accessible via at least two access openings positioned in the folding wall. The access openings and the handle straps are separated from an interior of the side-gusseted bag by a sealing strip on the inside of the folding wall. The handle straps leave at least a gap between them along the fold line for a folding area of ​​the sealing strip. The handle straps are positioned under a cover strip that is part of the folding wall. The two ends of the handle straps are fixed to the inside of the folding wall with fastening connections.

[0002] Such a gusseted bag is known, for example, from DE 20 2016 106 765 U1. However, in practice, it has been shown that individual handle straps or even the cover strip are occasionally torn out during transport of the gusseted bag using the carrying handle when the gusseted bag is filled with a heavy product.

[0003] The invention is based on the object of providing a side-gusseted bag made of plastic film of the type mentioned at the outset, in which no handle straps tear off at the carrying handle while carrying the side-gusseted bag, even if the side-gusseted bag is filled with a heavy filling material.

[0004] This object is achieved according to the invention by a side-gusseted bag of the type mentioned at the outset, which has guide connections between the handle straps and the cover strip in the area between the fastening connections. The guide connections prevent the hand or individual fingers of an operator from reaching between one of the handle straps and the cover strip when carrying the side-gusseted bag, or even between both handle straps, and the cover strip, and thus either only one handle strap or even neither of the two handle straps but only the cover strip is gripped behind. The guide connections therefore necessarily guide the fingers or the hand of an operator between the handle straps on the one hand and the sealing strip on the other, so that the operator always has both handle straps grasped when the operator's fingertips are guided out of the further access opening.By always grasping both handle straps, the carrying handle is sufficiently stable even when the side-gusseted bag is heavy, so that the handle straps no longer tear.

[0005] In an advantageous embodiment of the invention, at least one of the guide connections is arranged centrally between the fastening connections of the associated handle strap and extends there over a central area of ​​at least 5 cm, in particular at least 8 cm. Particularly preferably, both guide connections extend in the aforementioned manner. It has been shown that the guide connections exert their primary effect, particularly in this area in the middle between the fastening connections. In practice, incorrect operation of the carrying handle can thus be effectively prevented to a large extent.

[0006] Advantageously, at least one of the guide connections in the central area is free of interruptions extending over a distance of more than 15 mm, in particular more than 10 mm, parallel to the nearest adjacent access opening, and in which the handle strip is not connected to the folding wall. This effectively prevents an operator's finger from getting between the handle strip and the cover strip in the central area, thus preventing it from reaching behind the handle strip and limiting the stability of the carrying handle. Particularly preferably, all guide connections of the side-gusseted bag are designed as described above.

[0007] In an advantageous embodiment of the invention, at least one of the guide connections in the central area is designed to be continuous. This prevents operators with very narrow fingers from inserting individual fingers between the respective grip strip and the cover strip instead of grasping the grip strip with these fingers. Particularly preferably, all guide connections in the central area are designed to be continuous.

[0008] In a particularly preferred embodiment of the invention, at least one of the guide connections between the fastening connections is continuous. This ensures that an operator reaching into the first access opening with one hand does not mistakenly insert individual fingers outside the central area between the corresponding grip band and the cover strip, thereby limiting the stability of the carrying handle. Particularly preferably, all guide connections between the fastening connections are continuous.

[0009] The sealing strip is preferably connected directly or indirectly to the gusseted side wall with a circumferential edge seam. This prevents any contents inside the gusseted bag from escaping to the outside near the handle.

[0010] In an advantageous embodiment of the invention, the edge seam in the area of ​​the ends of the grip strips indirectly connects the sealing strip to the folding wall via the ends of the grip strips. Thus, the ends of the grip strips are still located between the sealing strip and the folding wall in this area, and the sealing strip is connected to the grip strips, which in turn are connected to the inside of the folding wall.

[0011] Particularly preferably, the edge seam in the area of ​​the handles is formed by a sealed seam that connects the sealing label, the ends of the handles, and the folding wall. The sealed seam thus connects three layers. This design allows forces exerted on the handles during carrying to be transferred particularly effectively into the material of the adjacent folding wall, thus preventing a handle from tearing out, even with heavy contents and unfavorable transport movements.

[0012] The fastening connections and / or the guide connections and / or the edge seam are preferably welded or adhesive connections.

[0013] It is advantageous if the grips are made of flat foil strips and the distance between the grips is smaller than the width of the grips.

[0014] The access openings are preferably formed by two slits in the folding wall, extending on either side of the fold line. Particularly preferably, the slits run along the mutually remote edges of the handle straps.

[0015] In a particularly preferred embodiment of the invention, the slots are designed as tearable weakening lines in the folding wall.

[0016] Further advantageous embodiments of the invention can be seen from the schematically illustrated embodiment described below; they show: Fig. 1a gusseted bag according to the invention, Fig. 2a detail enlargement of the article from Fig. 1 showing the area of ​​the carrying handle and Fig. 3 the object from Fig. 2 in a sectional view along line III-III.

[0017] The features of the exemplary embodiment described below may also be the subject of the invention individually or in other combinations. Elements of the invention with equivalent functions are provided with a common reference number where appropriate.

[0018] Fig. 1 shows a side-gusseted bag 2 according to the invention made of plastic film, in which in a flat, folded, empty state, which is in Fig.1 not shown, at least one folding wall 4 is folded in two layers between two main walls 6, 8 along a fold line 10. On either side of the fold line 10, two access openings 12, 14 are arranged in the folding wall 4, through which a carrying handle 18 arranged on the inner side 16 of the folding wall is accessible.

[0019] Fig. 2 shows an enlarged detail of the area of ​​the access openings 12, 14 from Fig. 1 in a view rotated by 90°. For clarity, the elements of the carrying handle 18 arranged on the inner side 16 of the folding wall 4 are shown with dashed lines to clarify their arrangement. Fig. 3 also shows the excerpt from Fig. 2 in a sectional view along the line III- III. The following explanations refer to both representations.

[0020] The carrying handle 18 arranged on the inner side 16 of the folding wall 4 has two handle straps 20, 22, which are arranged on either side of the fold line 10 and are accessible via the two access openings 12, 14 positioned in the folding wall 4. The access openings 12, 14 are separated from an interior space 26 of the gusseted bag 2 by a sealing strip 24 on the inner side 16 of the folding wall 4. The edge contour of the sealing strip 24 is in Fig. 2 represented by a dashed line. The gripping straps 20, 22 leave a gap 28 between them along the fold line 10 for a folding area of ​​the sealing strip 24. The gripping straps 20, 22 are positioned under a cover strip 30, which is part of the folding wall 4. The cover strip 30 is therefore understood to be the part of the folding wall 4 that conceals the gripping straps 20, 22 from the space outside the side-gusseted bag 2. In the exemplary embodiment, this is at least the area of ​​the folding wall 4 between the two access openings 12, 14.

[0021] The ends 32, 34, 36, 38 of the handle straps 20, 22 are fixed to the inner side 16 of the folding wall 4 with fastening connections 40.

[0022] Between the grip tapes 20, 22 and the cover strip 30, guide connections 42 are arranged in the area between the fastening connections 40. The fastening connections 40 and the guide connections 42 are welded or adhesive connections. The guide connections 42 are preferably arranged centrally between the fastening connections 40 of the respectively associated grip tape 20, 22 and extend there over a central area 44 of at least 5 cm, in particular of at least 8 cm.

[0023] The sealing strip 24 is connected directly or indirectly to the folding wall 4 by a circumferential edge seam 46. In the exemplary embodiment, the sealing strip 24 is connected to the folding wall 4 directly via the edge seam 46 in the areas in which it rests directly on the inner side 16 of the folding wall 4. In the areas in which the ends 32, 34, 36, 38 of the gripping straps 20, 22 are still arranged between the sealing strip 24 and the inner side 16 of the folding wall 4, the sealing strip 24 is only indirectly connected to the folding wall 4 via the gripping straps 20, 22. The edge seam 46 connects the sealing strip 24 to the gripping straps 20, 22 there, which in turn are fixed to the inner side 16 of the folding wall 4 via the fastening connections 40.In the exemplary embodiment, the edge seam is formed, at least in the area of ​​the ends 32, 34, 36, 38 of the handle straps 20, 22, by a sealed seam 48 that connects the sealing label 24, the ends 32, 34, 36, 38 of the handle straps 20, 22, and the folding wall 4. The sealed seam 48 thus welds three layers together in this area. This allows forces exerted on the handle straps 20, 22 during carrying to be distributed throughout the material of the folding wall 4, effectively preventing an end 32, 34, 36, 38 of the handle straps 20, 22 from being torn out, even with heavy contents and / or during unfavorable transport movements of the gusseted bag 2.
