Abstract
A fluid dispensing closure includes a housing having a base for securement to a container and a peripheral wall extending from the base toward an open end spaced from the base. A flexible resilient liner is captured within the peripheral wall of the housing, and has a flange extending through the open end of the housing peripheral wall. A flow tip has a body captured within the liner and an outer end extending through the open end of the housing peripheral wall and through the flange of the flexible resilient liner. The flow tip has at least two fluid flow passages disposed within the liner, and a circumferential channel underlying the flange and interconnecting ends of the passages. Pressure applied to the flange by fluid in the passages and channel expands the flange away from the flow tip and channel to permit egress of fluid from the channel, and removal of such pressure allows resilient collapse of the flange over the channel to seal the passages. The circumferential channel provides improved control of fluid flow from the dispensing closure.
