ABSTRACT:
A plastic closure includes a closure shell having a base wall and a peripheral skirt, and a sealing liner disposed on the base wall of the closure. The sealing liner includes an outer sealing layer of resilient resin secured to the base wall within the skirt, and an inner layer of barrier resin underlying the sealing layer. The base wall and the sealing layer have opposed flat surfaces, one of which has a pocket in which the barrier resin layer is disposed. The sealing layer has a periphery that extends beyond the periphery of the barrier resin layer, so that the sealing layer completely overlies and covers the barrier layer.
