ABSTRACT:
A molded closure for a liquid container comprising a thermoplastic elastomer and a blowing agent. The molded closure is particularly suitable for use as a synthetic wine cork in a wine bottle. The molded closure does not permit passage of oxygen into the container, does not absorb oxygen from the contents of the container, can be removed from the container using a corkscrew without significant expansion, crumbling or disintegration, does not significantly taint a liquid in the container, permits the container to be placed horizontally immediately after insertion of the molded closure, and can permanently retain printed matter on its surface.
