Abstract
The present invention mechanically propelled, liquid metered dispenser includes a main housing with liquid storage and a liquid advancing component for either allowing liquid to flow out or assisting in the flow of liquid out of the main housing by exerting pressure, into a metered dosage dispensing chamber in response to a loading movement of a cocking mechanism. The chamber has an inlet connected to the main housing with a one-way valve to only permit flow of liquid into the chamber. The chamber also has an outlet orifice for dispensing liquid therefrom in a metered amount. The chamber has a reciprocal plunger and has a load and release component connected to it, which includes a cocking mechanism, a locking mechanism, and a spring. The cocking mechanism is functionally connected to the plunger so as to move in harmony therewith, or, more preferably, to move a relatively short distance relative to the distance traveled by the cocking mechanism.
