Definitions

  • the invention relates to a carrier bag made of thermoplastic material with side walls, with the upper edge areas of which are turned inwards, handle loops made of similarly flexible material are connected in a materially bonded manner.
  • Such carrier bags are already in use as shopping bags, but they have the disadvantage that they are open at the top and therefore do not protect the goods inside against rain etc.
  • textile carrier bags made of thermoplastic which protect the textile goods transported in them from rain by a corresponding flap.
  • Such textile carrier bags generally have handles made of relatively rigid plastic, which are welded to the upper edge regions of the carrier bag by means of corresponding reinforcing webs.
  • These previously known bags have decisive disadvantages with regard to their manufacture and their recycling.
  • different plastic processing machines are necessary in the production, since the carrying bag and the handles are each made of a different plastic material consist.
  • the solid handles produced by injection molding must be separated from the rest of the carrying bag by hand before they can be regranulated separately from the thermoplastic.
  • carrier bags For the manufacturer of carrier bags, there is a need to produce carrier bags from thermoplastic that are multifunctional, i.e. can be used both as a conventional carrier bag for food, etc. and as a textile carrier bag for goods to be protected from rain.
  • this carrier bag should be as simple as possible and therefore inexpensive to manufacture, and on the other hand it should be easy to dispose of.
  • the edge area of one side wall extends beyond the edge area of the other side wall.
  • This protruding edge area has a slit-shaped incision in the area of the grip loops.
  • the protruding edge area itself can be used as a rain-protecting closure flap in a particularly simple manner when used as a textile carrying bag.
  • the carrier bag is to be used as a standard carrier bag for goods that are not to be protected, the edge area can be folded outwards onto the side wall. As a result, there is advantageously no need to separately form a closure flap to be provided on the carrying bag, which in particular leads to a simplification of the manufacturing process.
  • the inwardly folded edge regions of the carrier bag can be integrally connected to the respectively associated side wall along their inwardly open edge.
  • the edge areas are not only on the lateral boundary edges the side walls are integrally connected, ie welded or glued.
  • the stability of the edge regions of the carrier bag is advantageously increased, in particular an inadvertent tearing is made more difficult.
  • a weld seam or adhesive line is advantageously arranged essentially parallel to the envelope fold between the envelope fold and the incision.
  • an unintentional pulling apart of the edge region when the handle loops are inserted into the incision is advantageously prevented.
  • This also reinforces the protruding edge area.
  • the handle loops can be continuously welded to the edge areas at their ends, i.e. that the correspondingly flat weld spot connects the respective handle loop end to the two superimposed film areas of the corresponding edge area in a materially bonded manner. This through-welding additionally fixes the foils lying on top of one another in the edge areas and thereby simultaneously increases the stability of the carrying bag.
  • the carrier bag made of thermoplastic material 10 shown in FIG. 1 has two side walls 12, 14 and a bottom fold 13.
  • the side walls 12, 14 are laterally welded together.
  • the side walls 12, 14 are folded inwards to form edge regions 16, 18, the inward edge edges 24, 26 coming to lie approximately at the same height.
  • an edge region 16 projects beyond the other edge region 18, as is shown in FIGS. 1 and 2.
  • a final weld seam 23 or 27 is drawn along the edge regions 16 or 18 along its inwardly open edge 24 or 26.
  • the edge regions 16 and 18 are thus closed laterally by the welding edges of the side walls and towards the bottom fold 13 by the welding seams 23 and 27.
  • the grip loops 20, which are also made of thermoplastic, are welded at their ends 32 and 34 to the edge regions 16 and 18, respectively, via flat spot welds 36 and 38. In this case, the welding connects the respective handle ends to two foils lying one above the other and forming the respective edge region.
  • the projecting edge area 16 has a slot-shaped incision 22 in the area of the grip loops 20.
  • the handle loops 20 can be inserted through this incision 22 if the projecting edge area 16 is to serve as a flap protecting against rain etc.
  • FIG. 3 shows the carrier bag in one of its states of use.
  • the tote bag In the state of use shown there, the tote bag is used as a tote bag for goods not to be particularly protected, the overhanging edge area 16 being folded out onto the side wall 12.
  • the goods carried in the carrying bag 10 are not protected against rain etc. in this state of use.
  • the tote bag shown in Fig. 3 can be easily converted into a textile tote bag in which after inserting the goods into the tote bag 10, the flap 16 is slipped over the opposite side wall 14 after inserting the grip loops 20 into the incision 22, this in the tote bag transported textile goods are protected from rain etc.
