Abstract:
The invention concerns a closure for a cylindrical can (10) The closure includes a flexible member (11) of the easy-open type secured across the open end of the can (10). A rigid, screw cap (22) is screwed over the thus sealed end of the can. An annular, resilient member (24) depending downwardly from the underside of the end wall of the cap (22), engages the membrane (11) in the vicinity of the end flange (18) of the can body (10) thereby strengthening the seal between the membrane (11) and the flange (18). This advantageously permits cooking of the contents of the can with the flexible membrane (11) in situ, thereby giving rise to a can having an easy-open end, the contents of which can are cooked and sterilized using conventional processing lines.
