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.
