Abstract
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.
