A metal lid is used in combination with a polymeric container to provide air tightness of the container even if there is shrinking or expansion of the polymeric substance (page 1, lines 14-31). Fritz does not disclose that the polymeric substance can be thermoplastic and injection molded or that the lid can be an injection molded thermoplastic body, and does not disclose a seal membrane sealed to the inner wall of the container.
