Abstract
Internal, liquid flow passages in a dispensing stopper which might accumulate residue from the liquid being dispensed are eliminated in a structure including a stopper base (24) adapted to be mounted on the mouth (12) of a bottle (10). A seal (64) is mounted on the base (24) and includes a fixed section (66) affixed to the base (24), a movable gasket section (38) movable toward and away from the stopper base (24) and away and toward a sealing surface (16) on a bottle (10) on which the base (24) is mounted, and an integral, thin web (76) of resilient material peripherally interconnecting and sealing the fixed section (66) and the movable gasket section (38). An actuator attachment section (52) is affixed to the movable gasket section (38) and a lever (36) is pivoted to the base (24) and to the actuator attachment section (52) at spaced locations.
