Abstract
A closure for a food can including a foil end panel bonded to an intermediate ring which is fixed to the can body. The foil panel comprises a diaphragm having a centre panel which included at least one concentric bead. The profile of this beaded panel is selected so that its downward position is no greater than the lowest point of the intermediate ring. The provision of the bead(s) reduces pressure differences experienced by the diaphragm, particularly during processing of the can contents, due to the volume increase available from the beads.
