Abstract: A dispensing closure assembly includes an outer closure body having an upper tubular portion which can function as a mouthpiece for users. The closure assembly includes a flexible valve member mounted within the tubular portion of the closure body for dispensing of liquids or like contents by either the application of suction by a consumer, or by squeezing the associated container. By the provision of a liquid seal lip which coacts with an inside surface of the flexible valve member, the closure assembly can be configured to facilitate convenient use by consumers, while avoiding undesirable leakage attendant to normal handling during use.

Abstract: A composite closure includes a plastic outer closure cap, and an inner sealing liner positioned adjacent to an inside surface of a top wall portion of the outer cap. In order to enhance sealing integrity with an associated container, the liner is configured to include inward and outwardly facing sealing surfaces, with the provision of an annular sealing bead providing a top/side seal with an associated container, and an annular sealing plug 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.
