Definitions

• the invention relates to transport containers for flowable materials, in particular for bitumen in heated or cold condition, wherein the container body of the transport container has a substantially truncated pyramidal shape formed with flexible material bottom, side walls and optionally top surface with filling opening, and wherein the side walls in the lower region near the bottom by
• Stabilizing agents are reinforced against deformation.
• Transport containers made of flexible material are often brought to the market with the designation Big Bag or Flexible bulk container and serve mainly for the transport of pourable or flowable goods.
• the present invention is based on a prior art, as disclosed, for example, by AT 505 805 A1.
• This application is concerned with the stabilization of the shape of such a flexible transport container after
• Stabilizing agents are provided, which are fed or sewn into the tissue panels.
• the concrete disclosure in the figures shows the arrangement of crossed folds which are sewn into the material of the side walls, the seams ending in the course of the fabric panels.
• Reinforcing effect is of the quality of the needlework and the quality of the Fabric material, which does not always make it easy to predict the stabilizer effect on mass products.
• sutures tend to burst, either causing the suture to open and rendering the stabilizer effect ineffective, or in the worst case, tearing the transport sack.
• Seams are always associated with a weakening of the sewn tissue.
• sewn folds end in the fabric material of the side walls, so that the sometimes very high tensile forces are at least introduced into the tissue and overstretch and damage this tissue in some parts.
• Bitumen is liquid to viscous only at higher temperatures and solidifies at lower temperatures to a cool melt.
• Transport container no longer fit into the containers used for overseas transport.
• the problem of dimensional stability can be exacerbated when low temperatures cause the commonly used material, such as polypropylene or polyethylene, to lose its strength.
• the object of the present invention is to provide packaging containers of the type mentioned, which are self-stabilizing during filling of the liquid bitumen or similar flowable substances and also remain free after settling of the contents and in particular the solidification of the bitumen, without the desired shape to lose.
• the strength of the container should also be at low
• the object is to avoid the disadvantages described above, and form the stabilizing means for the shape of the container body such that the tensile forces occurring are well absorbed on all sides, so that it does not come in the hard practice of transport industry to a bursting of the transport container , Moreover, there is a need for such
• Another object is to relieve the tissue of the side walls of the tensile forces and a bias of the stabilizing agent should be achieved.
• the stabilizing means are designed as stabilizer straps, each of which criss-cross connects the bottom corner areas with the adjacent side edges, the fastening points of the stabilizer straps lying on the side edges within the bottom two-thirds of the overall height of the container body.
