Definitions

  • the present invention relates to a plastic carrier bag and a bag stack comprising a plurality of plastic carrier bags according to the invention.
  • Plastic carrier bags are widely used in retail and wholesale. They have to be stored space-saving and must always be available to the user in the same reliability in large numbers. For this purpose, pocket stacks have established themselves, as they are regularly found, for example, vegetable counters of supermarkets. Such bag stacks can be hung, for example, in suitable stand devices in order to be available to the user. Generic bag stacks can be found in the two British Patents GB 2 391 538 B and GB 2 395 938 B described.
  • the bag stacks disclosed in these documents comprise a plurality of plastic carrier bags which include a front and a back wall, the front and rear panels defining a bag body having a closed bottom end and closed sides and an opening end and two spaced gripping pieces.
  • the front and rear walls each comprise an approximately central center strip, wherein the rear strip of the front pocket is always connected to the front strip of the underlying pocket separable.
  • the carrier bags are separably connected to a holding or fastening device arranged between two grips. This fastening device accordingly has separable weakened areas both with both handles and with the upper end of the front and rear center strips the shopping bags.
  • the present invention therefore an object of the invention to provide bag stacks available that ensure reliable handling and a flexible tearing of each bag pocket, especially for the last or lowermost pockets of a bag stack, the mass production to be unproblematic and completely automated can be.
  • the invention was also based on the object, a To provide plastic carrier bag designed in such a way that it can be used in a bag stack that meets the above requirements.
  • a plastic carrier bag was found, hereinafter also referred to as the first embodiment comprising a front wall and a rear wall, wherein the front and rear walls define a bag body having a substantially closed bottom end and at least partially closed sides and an at least partially open, opposite the bottom end opening end, two spaced apart grips, and at least one holding device for the carrier bag, wherein the front wall has a, in particular integrally connected, front strip which extends between the two grips away from the opening end, and wherein the front and rear strip and the rear wall has an, in particular integrally connected, rear strip which extends between the two gripping pieces away from the opening end, and wherein the front wall and / or the rear wall in each case via the located between the two grips opening end of front or rear wall are separably connected to the holding device via at least one weakening or perforation, wherein the front and / or the rear strip in each case via the located between the two grips opening end of the front or rear wall with the holding device for min at least one weakening or
  • An embodiment of the invention may accordingly be designed in such a way that the front and the rear strip and the holding device are present separately or separably connected side by side, wherein the holding device may have, for example via a suitable opening or a penetration to the bag or the bag stack to hang on a stand device.
  • the holding device may have, for example via a suitable opening or a penetration to the bag or the bag stack to hang on a stand device.

  • these lateral connecting sections can be arranged, for example, perpendicular to the strap section, which preferably runs transversely to the longitudinal axis of the pocket. While in this case the lateral connecting portions have weakening areas in the region of the opening edge, the front or rear strip, in particular at the end opposite the opening end, has a separable connection or weakening area with the bow section connecting the lateral connecting sections.
  • the weakening or perforation areas between the holding device, in particular the lateral connecting arms and the pocket body or the front or rear of the carrying bag can hereby lie in the region or at the level of the opening edge, above the opening edge or even below the opening edge, i. taken in the bag body.
  • the perforation areas are arranged slightly above the opening edge.
  • a plastic carrier bag hereinafter also called second embodiment, comprising a front wall and a rear wall, wherein the front and rear walls define a bag body with a substantially closed bottom end and at least partially closed sides and an at least partially open mouth end opposite the bottom end, two gripping pieces spaced apart from each other, and at least one holding device for the carrying case, the front wall comprising a front strip extending between the two handles away from the opening end, the rear wall comprising a rear strip which extends extends between the two gripping pieces away from the opening end, wherein the holding device is connected to at least one connecting portion via weakening or perforation regions separable connected to the front and / or rear strip, wob ei the holding device forms at least two, in particular symmetrical, holding openings together with the front and / or rear strip and wherein the holding device has at least two lateral connecting sections to the front and / or rear strip and a connecting portion connecting these strap sections, and wherein the front and / or or the
  • the holding device is present connected to at least three spaced connecting portions via weakening or perforation separable with the front and / or rear strip.
  • This can be accomplished, for example, in that the portion of the front or rear strip opposite the opening end is detachably connected to the holding device at a first portion is and that the holding device has extending toward the opening end portions which form a separable connection closer to the opening end with the front and rear strips.
