Abstract
A metal can body comprises an end wall and a tubular side wall. The side wall has upper and lower cylindrical portions joined by a plurality of concave flexible panel portions and ribs. The benefit arising from the flexible panels in the side wall is the ability to attenuate the internal pressure changes arising during thermal processing of lidded cans by providing a elastic mechanism which enhances the change in internal can volume.
