Abstract
A method is provided for forming an end closure for a surrounding sidewall of a container, such as an aluminum can. The method includes forming a central body panel oriented transversely to the central axis of the can and forming an outer surrounding margin portion joined to the sidewall such that the margin portion has a support section oriented longitudinally relative to the sidewall. A portion of the margin is corrugated to provide a rib structure having longitudinally extending first rib components located on the support section. This method can be accomplished during the ironing and doming of a can.
