An improved reusable storage container is disclosed with a varying wall thickness. Specifically, the vertical corner sections have a greater wall thickness than the side and end panels and, possibly, the bottom panel. Further, the various corner sections or corner junctions of the structure may also have a greater average wall thickness than the vertical, side or end panels and, possibly, the bottom panel. The improved container is fabricated using an extrusion blow molding process with a shaped die in combination with parison programming so that the thickness of the extruded parison is non-uniform both radially and axially. An adjustable die for carrying out the extrusion blow molding process is also disclosed.
