Abstract

A liquid dispenser and cap valve assembly therefor is provided to dispense a controlled dose of liquid. The liquid dispenser and cap valve assembly therefor is particularly suitable for dispensing liquid soaps and lotions. The liquid dispensing cap valve assembly comprises a dosing cap having an upper portion and a lower portion, a divider piece mounted in the dosing cap, and two oppositely acting check valves. The lower portion and the divider piece defines a dosing reservoir. A first check valve mounted on the divider piece serves to open and close a liquid passageway from a storage container to the dosing reservoir, depending on a fluid pressure in the dosing reservoir. A second check valve fixedly mounted to the lower portion serves to open and close a liquid passageway from the dosing reservoir to an outlet orifice, acting oppositely to the first check valve. The liquid dispenser comprises a liquid storage container, the cap valve assembly connected to the storage container, an actuator assembly having an actuation lever, and a mounting member. The mounting member provides first and second pivotal mounting locations for the actuation lever. When the actuation lever is mounted in the first location, the lever serves to actuate a liquid dispensing movement by pivotal motion in one direction. Conversely, when the lever is mounted in the second location, it serves to actuate the movement by pivotal motion in an opposite direction.
