Definitions

  • a handle hole pocket comprising a bag body substantially of thermoplastic material having a front wall, a rear wall and optionally a first and / or second side wall, which at least partially along the first and second side edges of the front and rear walls of the front and rear wall Rear wall connects, wherein the front wall, the rear wall and optionally the first and second side walls have an opening edge and an opposite bottom edge and in the region of the opening edge inside and / or outside at least in sections, a seam containing at least partially thermoplastic material, in particular substantially of thermoplastic material, and at least one through-opening in the front wall and / or the rear wall, respectively, in particular centrally, between the first and second side edge of the front wall and rear wall, wherein the access opening of the front wall and / or the access opening of the rear wall is present or present in the hem of the front or rear wall.
  • Carrying bags made of plastic materials come in a variety of forms and for any transportation purposes used. While with smaller-sized plastic carrier bags, the carrying handles are regularly formed in the bag walls by optionally reinforced punched through openings, come with larger-sized plastic carrier bags separately separately attached to the front and rear wall straps different length used. Usually used for the bag walls and the carrying straps thermoplastic plastic materials which are either identical or homogeneously miscible in the melt. In this way, the carrying straps can be thermally melted. Such conventional loop pockets can be found for example in the DE 101 16 920 A1 , of the WO 01/51372 A1 and the DE 40 12 897 A1 disclosed. A disadvantage of the known loop carrying bags is still their quite expensive production. Also, the wear resistance usually leaves nothing to be desired.
  • Plastic loop carrying bags are often disposable products made in large numbers by machine or semi-mechanical means. Although it is therefore a mass product in the case of loop carrying bags, great care is nevertheless required in their manufacture in order to ensure a sufficient load-bearing capacity, especially in the case of larger bags, during transport. A weight-related tearing of a strap is unacceptable. Accordingly, industrial users of loop carrying bags, such as department stores and hypermarkets, place high demands on the quality of such bags. The same applies to grip hole carrier bags made of plastic.
  • the present invention therefore an object of the invention to provide bags made of plastic available that do not suffer from the disadvantages of the carrier bags of the prior art and are particularly suitable for the reliable transport of heavy loads, and can also be produced in a simple and cost-effective manner in automated series production.

  • a handle hole pocket was found, in which the seam of the front wall and / or the seam of the rear wall, viewed in the direction of the opening edge to the bottom edge, at least partially beyond at least one passage opening of the front or rear wall, in particular all für Bachsö Maschinenen of front or rear wall, glued to the adjacent front or rear wall of the bag body along at least one third connection point and / or is thermoplastically welded or are.
  • the bag body of the bags according to the invention can assume any geometric shapes.
  • the pocket body surfaces are square or rectangular in dimension, with the front wall and the rear wall preferably having an identical blank.
  • the opening edge of the bag body is generally formed by opposing edge courses of the front and rear walls and optionally of the first and second side wall.
