Abstract

A composite closure (10) includes a plastic outer closure cap (12), and an inner sealing liner (22) positioned adjacent to an inside surface of a top wall portion (14) of the outer cap (12). In order to enhance sealing integrity with an associated container, the liner (22) is configured to include inward and outwardly facing sealing surface (32), with the provision of an annular sealing bead (28) providing a top/side seal with an associated container, and an annular sealing plug (34) fitting within the mouth of an associated container for providing an inside seal. The closure construction has been found to maintain sealing integrity with an associated container when the closure and container package is subjected to relatively high temperatures.
