This relates to an end, preferably a bottom end, for a metal shipping container wherein the end panel is recessed so as to bear the weight of the product shipped within the container. The invention particularly relates to the reinforcing of the end panel by an annular rib formed in the radially outer part of the end panel near to but spaced from the seam which joins the end to a container body. The annular rib is concentric to the container and is axially downwardly offset so as to be axially upwardly opening. The reinforcing rib is of a preferred depth and width ratio with respect to one another and to the container diameter.

Reinforced structure for steel ends of cylindrical shipping containers

A drum having a blow molded liner wherein the liner has a neck which extends through an opening formed in a wall of the drum. A closure assembly is provided for association with the neck both to retain the neck relative to the drum and to close the neck. The closure assembly includes a retainer and a closure member, the retainer including inner and outer concentric walls joined in spaced relation by a bridging portion. The neck is threadedly engaged with the outer wall and is received between the two walls with a terminal portion of the neck being wedgedly deformed to assure a seal between the retainer and the neck. A seal is also provided between the closure assembly and the neck. The inner wall defines a dispensing opening and has threadedly engaged therein a closure element. A tamper indicating overcap covers the closure assembly. The closure assembly has an interlock with the drum wall surrounding the opening. The retainer inner wall also has an integral rupturable diaphragm preventing initial entry into the liner.
