Definitions

  • the invention relates to a carrier bag, in particular a textile carrier bag, made of thermoplastic material according to the first part of claim 1. Furthermore, the invention relates to a method for producing such carrier bags.
  • a carrier bag made of thermoplastic material is also known. This has a handle hole assigned to each bag wall on the upper edge of the bag, the two carrier bag walls being reinforced by an envelope in the area of the handle holes. If such bags are to be used as relatively wide textile bags, a handle is used instead of a handle hole provided in the bag wall or a handle made of lobed material relatively solid injection molding material, as is known from DE-GM 73 19 621.
  • handles are formed in one piece with reinforcing webs running lengthways along the edge of the pocket, which after welding the handles to the carrying bag form a stiffening of the upper edge of the textile carrying bag in such a way that the upper edge remains relatively straight when carried and the textile goods carried in the bag are not compressed.
  • these previously known bags basically meet the requirements that are placed on a bag for the transport of textile goods.
  • these previously known bags have decisive disadvantages with regard to their manufacture and their recycling.
  • various plastic processing machines are necessary for the production, since the carrying bag and the handles each consist of a different plastic material.
  • the solid handles produced in the injection molding process have to be separated from the rest of the carrying bag by hand before they can be regranulated separately from the thermoplastic.
  • this object is achieved on the basis of a generic textile carrier bag according to the first part of claim 1 by the features of the characterizing part of claim 1.
  • the edge area of the one side wall consists of an edge area forming a folded edge and an adjoining Area that can be folded back, to which the closing flap then connects, forming a further folded edge.
  • the edge areas turned inwards are connected to the side walls by welds running over the entire length of the pocket.
  • the closing flap rests on the edge of the opposite side after the bag has been closed, without it due to kinks or folds it would be feared that it would not cover this edge area in places.
  • the protrusion of the edge area folded inwards in the one side wall can be turned upwards, so that the edge area is already formed in the delivered bags.
  • the protrusion can continue to run parallel to the side wall of the tote bag and, if necessary, can be turned up by the user, so that the closing flap is formed only after appropriate folding again.
  • this projection can have perforation lines on the side, along which the user can tear it open in order to be folded over to form the closing flap.
  • a further weld over the entire length of the pocket can be provided between the two parallel folding edges of the edge regions of the one side wall.
  • pressure-sensitive adhesive points are arranged on the side wall, over which the closing flap is placed when the bag is closed, so that the closing flap can engage in releasable engagement therewith.
  • a first embodiment of the invention as shown in Figures 1 and 3, has a bottom fold 2 and side walls 3 and 4. At the end faces, it is connected by welding edges, not shown.
  • FIG. 2 a A method for producing the bag according to the invention is explained on the basis of the sectional representations a), b), c) and d) in FIG. 2.
  • a flat web is first inserted into a half-tube with a bottom gusset 2, the later side wall 3 being longer than the later side wall 4, so that there is a strip-like protrusion thereon.
  • the two edge regions of the side walls 3 and 4 are then placed inwards, as can be seen in FIG. 2 b), wherein the upper folding edges 5 are at one level and run parallel to one another. At a distance from these upper folded edges 5, the areas turned inwards are firmly connected to the side walls 3 and 4 by longitudinal welds 6 and 7.
  • the welds on the side wall 3 and those on the side wall 4 are approximately the same distance from the folded edges 5.
  • the handles which are made of the same material as the bag itself, are then inserted into the half-tube and welded 8 and 9 to both the folded parts and the outer parts of the walls 3 and 4 welded.
  • the area of the web protruding downward over the weld 6 is gem. 2 d) first folded up and then folded down again around the folded edge 5 '. This last folding results in a closing flap 12 which can be placed over the folding edge 5 of the side wall 4 to close the carrying case.
  • the side wall 3 has an incision 10 through which the handle 11 welded to the side wall 4 can be inserted, so that the closing flap 12 can easily rest on the outer wall 4 from the outside.
  • the arrangement of this incision 10 is particularly according to the perspective view. Fig. 4 can be seen.
  • tack adhesive points 16 and 19 can be attached in the upper region on the side wall are initially covered to the outside by silicone strips 17 and 18. If these strips 17 and 18 are now pulled off, and the handle 11 is pushed through the incision 10 from below, the flap 12 lies on the outer pocket wall and can be detachably connected to these pressure-sensitive adhesive points 16 and 19 by light pressure.
  • FIG. 5 shows in the five detailed representations a) to e) a further method for producing a further embodiment of the bag according to the invention. 1, wherein the attachment of the optional additional weld seam 13 and the attachment of the PSA points 16 and 19 are not shown.
  • a web is first folded in a first step a) into a half-tube provided with a bottom fold 20.
  • the two upper edges of the half hose are gem.
  • the lower edges of the wrapped parts are then connected to the side walls 3 and 4 over the entire length of the pocket by weld seams 21 and 22, which run along and parallel to the folded edges.
  • a U-shaped strip 23 is inserted into the half-tube in such a way that its longer leg 24 is included in the weld seam 21, as can be seen in FIG. 5 c).
  • the handles 25 and 26 are inserted into the half-tube, which are then connected by welding seams 27 and 28 both to the parts of the half-tube turned inwards and to the outer walls of the half-tube (see FIG. 5 d)).
  • the U-shaped strip 23 is then folded up around the weld seam 21, so that this creates a closing flap 29, which in turn has an incision (not shown in more detail) on its upper folded edge 30 for inserting the carrying handle 26.
  • FIGS. 6 and 7 and 8 each show two further embodiments of the carrier bag according to the invention. Identical parts are provided with the same reference symbols in the figures.
  • the area 31 projecting downward beyond the weld seam 6 has not been folded upward in the finished bag. If necessary, this can be pulled up out of the pocket by the user and placed over the handle 11 ', the handle 11' protruding upward through the incision 10 (see FIG. 6). So that the downwardly projecting area 31 can be pulled out of the pocket, it is necessary that it is not fixed laterally. It therefore has lateral incisions or optionally perforation lines 33.
  • the region 31 projecting downward is in contrast to the embodiment according to FIG. Fig. 6 folded inwards once so that it has a U-shape in cross section.
  • the incision 10 is provided in the area of the pre-folding edge 32.
