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. During the process of applying the closure to a container, the flexible foil sealing disk is formed, heated, and is tack adhered to the rim of the container. A closure cap having downwardly extending spaced sealing flanges is then screwed onto the container. 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 cap has been applied and tightened down, the two part closure is subjected to a second heating step to fully activate the heat sensitive adhesive carried on the under surface of the flexible foil sealing disk thus securely adhering the flexible foil sealing disk to the container. Once the closure has been opened and the foil sealing disk removed, the container can be released by using the flanged linerless closure cap. Several preferred embodiments of flexible foil sealing disk forming and applying assemblies are usable to form the foil disks and to tack adhere them to the mouths of containers.
