Definitions

  • the invention relates to a device for protecting a large-volume container during the. Storage and transportation of liquid, viscous, powdery and granular fillers, consisting of a pallet-like support body supporting the container on its underside and a casing body connected to the support body and laterally enclosing the container, and a process for their production.
  • Large-volume containers are used for the transport and storage of liquid, viscous, powdery and granular fillers, which usually have a capacity of 500 to 1000 liters and are made of plastic in a blow molding process. These containers have an upper, closable filling opening, while an outlet opening with a shut-off valve is arranged in the region of the bottom.
  • the container In order to be able to transport and store such a container easily and without damage, the container, with its mostly rectangular base, is supported on a pallet-like supporting body made of wood, metal or plastic, on which a casing body made of vertical and horizontal, welded rods, enclosing the container on the side is arranged from metal.
  • a metallic jacket body is particularly in the chemical industry and in Food sector disadvantageous and therefore undesirable.
  • the same securing device consisting of the supporting body and the jacket body is regarded as disadvantageous because on the one hand it is very complex to manufacture and on the other hand there is always the risk that the jacket body can detach from the supporting body. In addition, damage to the container cannot be ruled out due to the grid-like casing body.
