  • Patent number: 7025223
    Abstract: A grid casing for a container having a tendency to become electrostatically charged has a basic grid made of basic grid bars forming a basic grid mesh structure. The basic grid is primarily responsible for the strength of the grid casing. Additional grid bars are provided for forming a tighter grid mesh structure relative to the basic grid mesh structure of the basic grid.

  • Patent number: 5060815
    Abstract: A transport and storage container for flowable materials comprises an annular and erect outer wall member in the form of a gridwork of horizontal rods and vertical bars and having a lower edge, a generally planar floor member having an outer edge at the lower edge of the wall member and formed as a gridwork of horizontal bars not unitary with any of the bars of the wall member, and an inner vessel composed of a plastic material enclosed by the outer support member and supported on the bottom member. The bars of the planar floor member are separate from and not unitary with the bars of the wall member and the rods of at least one of the members have L-shaped end extensions that extend past the respective edge and are joined to the rods of the other member by welds. The upper edge of the wall member is provided with an annular collar formed by a profiled steel element welded to the tops of the steel vertical rods.

  • Patent number: 5058747
    Abstract: A transport and storage container for flowable materials has an annular and erect outer wall in the form of a gridwork of bars having a lower edge and provided at the edge with an annular stiffening bar and a pallet-like floor downwardly closing the wall, forming therewith an outer vessel, and provided with a plurality of wooden foot beams each having a ground-engaging lower surface, an upper surface, and a pair of ends. Respective steel plates on the upper surfaces of the foot beams each have bent-down ends overlying the respective beam ends. Fasteners such as screws or nails are engaged through the steel-plate ends into the respective beam ends. Integral connections are provided between each of the plates and the annular stiffening bar at the lower edge of the wall. An inner vessel composed of flexible plastic material is enclosed by the outer wall and supported on the floor.

  • Patent number: 5050765
    Abstract: A large-volume storage and transport container has a flexible wall inner vessel within an outer vessel of gridwork. The bottom of this outer vessel is likewise formed as a gridwork and stabilized by welding with additional bars if necessary. Pallet feet or other palletizing elements can be formed on the additional bars, welded to the bottom or otherwise attached thereto.
