A fluid dispensing closure includes a housing having a base with an internal thread or bead for securement to a container, and a peripheral wall extending from the base and converging toward an opening spaced from the base. A flexible resilient liner is captured within the peripheral wall of the housing. The liner has a flange extending axially through the opening at the upper end of the housing and radially overlying the peripheral wall of the housing. A flow tip, which has a body with at least one flow passage, is captured within the liner, and extends through the liner flange and the housing opening. Pressure applied to the flange by fluid in the passage resiliently expands the flange away from the flow tip to permit egress of fluid from the passage, and removal of such fluid pressure allows resilient collapse of the liner over the passage.

[ What is claimed is:] [1.]1. A fluid dispensing closure that comprises:a flow tip having an exterior peripheral surface and at least one fluid passage extending along said exterior peripheral surface from an inner end of said flow tip to a position spaced from an outer end of said flow tip,a liner of flexible resilient construction embracing said exterior surface of said flow tip forming an outer wall of said at least one passage, and having an outer end that overlies and closes said outer end of said at least one flow passage, anda housing exteriorly securing said liner to said flow tip, said outer end of said liner and said outer end of said flow tip extending through an outer end of said housing,such that pressure applied by fluid in said at least one passage resiliently expands said outer end of said liner away from said outer surface of said flow tip to permit egress of fluid from said at least one passage, and removal of pressure applied by fluid in said at least one passage allows collapse of said outer end of said liner over said outer end of said passage to prevent return of fluid to said passage.
