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.
