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.
