An extrusion is provided which includes an upper double sidewall and a lower bulbous portion forming an integral pallet structure. This extrusion can be cut to suitable lengths and welded at the corners to form a sealed rectangular container bottom. A bottom panel is welded around its peripheral edge to the extrusion lengths. Reinforcing I-beams can be placed across the bottom and laterally spaced openings can be cut in the ends and sides of the bottom portions for receiving fork-lift tines. These cut-out portions can be reinforced by tubes or channel members, as required. This structure minimizes the critical welding required to make a sealed container bottom, since only the corner welds and the bottom panel welds are located where air leakage can occur.

A container base comprising: four extruded segments forming opposed side sections and opposed end sections all having ends which are connected together to form a rectangular structure with four corners, each segment having an upper wall section and an integral bulbous lower pallet section with an outer wall, an inner wall spaced from said outer wall and a foot formed integrally with and extending between said inner and outer walls; a rectangular bottom panel having a peripheral edge which is sealingly attached to said segments between said upper wall section and said lower pallet section; a first pair of laterally spaced openings extending through said outer and inner walls of said end sections for receiving tines of a fork-lift; and a second pair of laterally spaced openings extending through said outer and inner walls of said side sections, centrally located from said opposite ends thereof.
