Abstract
A two part closure for a container is comprised of a flexible foil sealing disk together with a flanged linerless screw threaded closure cap. The cap's sealing flanges contact the flexible foil sealing disk on opposite edges of the container's mouth rim and, as the cap is screwed down, these flanges bring the flexible foil sealing disk into continuous, intimate sealing contact with the container rim. Additionally, the inner closure flange draws the portion of the flexible foil sealing disk situated within the container mouth tight to eliminate creases and wrinkles in the foil sealing disk. Once the closure has been opened and the foil sealing disk removed, the container can be resealed by using the flanged linerless closure cap.
