Definitions

  • the present invention relates to a container made of flexible material, essentially a round fabric made of polyolefins, on the upper edge of which two or more loops are sewn in accordance with the preamble of the claim.
  • GB-A-2 148 245 shows that twisting of the carrying straps has already been practiced, but always in order to stiffen the carrying strap so that an eyelet remains that allows the crane hook to be retracted.
  • the material strip forming a loop has a width of at least 90 mm and in that the middle part of each loop is twisted several times before it is sewn to the upper container edge is pulled together like a rope.
  • the container shown made of flexible material essentially consists of a round fabric 20 made of polypropylene tapes, which form warp threads 6 and weft threads 5.
  • a provided inner bag made of, for example, a polyethylene film can be seen through an inlet 23 or.
  • the valves can be closed by means of a cord 28.
  • Cover sheet 21 and bottom sheet 22 are webs of a film or a fabric. Containers of this type are known per se and have two or more loops on the upper edge.
  • each loop 1 is now formed from a relatively wide strip of material made of a woven fabric, a flat circular fabric or the like.
  • the aforementioned materials, the two ends of which 2 and. 2 'overlap the upper container edge 10 and laterally spaced from it with some seams 7 approximately parallel to the weft threads 5 are sewn, as the illustration clearly shows.
  • the central part 3 forming the suspension eye is further pulled together in a band-like manner in order to be able to hook this part up.
  • this is achieved, according to the invention, by rotating the material strip several times before sewing it onto the upper container edge.
  • a central transverse seam 4 prevents popping open.
  • a width of at least 90 mm or more for the material strip forming a loop has been found to be essential to the invention.
  • the greatest elasticity with the highest load-bearing capacity is also achieved if the round fabric of the container casing and / or the material strip forming the loops has warp threads lying two or more times one above the other.
