The annular skirt portion depends from the polymeric top wall portion. The annular skirt portion includes an internal thread formation for mating engagement with an external thread formation of a container. The polymeric annular skirt portion includes an interior surface and an exterior surface. The plug seal depends from the polymeric top wall portion. The continuous plug seal is spaced from the interior surface of the polymeric annular skirt portion. The top seal includes sealing gussets integrally connected thereto. The top seal and the sealing gussets depend from the polymeric top wall portion. The top seal and sealing gussets are located between and spaced from the plug seal and the annular skirt portion. ## Claims ### Claim 1 A closure comprising: a polymeric top wall portion; a polymeric annular skirt portion depending from the polymeric top wall portion, the annular skirt portion including an internal thread formation for mating engagement with an external thread formation of a container, the polymeric annular skirt portion including an interior surface and an exterior surface;
