Abstract
An end wall for a can body has a central panel (7) surrounded by a conventional expansion ring (8) which is connected to an inner wall (16) of a channel portion by an upwardly extending deformable annulus (17, 18) so that during thermal processing of a closed can having this end wall, the deformable annulus changes shape to permanently increase the container volume. The deformable annulus protects the side wall and ends of the can from excessive pressure so thinner container materials may be used.
