  • Patent number: 4010867
    Abstract: A two-piece can and method for making the same wherein the cup portion has a bottom panel integral with the sidewall. The interface of the bottom panel with the sidewall in the cup has a wall bead which is of the same outside configuration as the connection of the upper rim of the cup to the separate top panel. The bottom panel in the cup portion has a specific profile to withstand the internal pressures within the can during the recooking phase of the substance sealed within the can. The profile has a bottom bead which is closely adjacent the interface of the bottom panel with the sidewall and has a very tight radius between the sidewall and the bead to provide a strengthening rib for the prevention of buckling during the reheating phase.
