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.

1. A mechanically propelled, liquid metered dispenser, which comprises:(a) a main housing having liquid storage means to contain liquid advancing means; (b) a liquid advancing means in said main housing, adapted to automatically advance liquid from said main housing to a metered dosage dispensing chamber in response to a loading movement of a cocking mechanism; (c) a metered dosage dispensing chamber having an inlet connected to said main housing and having a one-way valve within said inlet to permit flow of liquid from said main housing liquid storage means to said metered dosage dispensing chamber and to prevent flow of liquid from said metered dosage dispensing chamber to said liquid storage means, and said metered dosage dispensing chamber having an outlet orifice for dispensing liquid therefrom in a metered amount, said metered dosage dispensing chamber being adapted to contain a reciprocal plunger means; (d) a load and release means connected to said metered liquid dispensing chamber, said load and release means including a cocking mechanism, a locking mechanism, a spring, and a plunger, said cocking mechanism functionally connected to said plunger, said plunger being connected to said metered liquid dispensing chamber, said spring being connected to said cocking mechanism to bias it to a first position, being a rest position toward said metered liquid dispensing chamber, said locking mechanism being connected to said cocking mechanism to lock it in a second position, being a stressed position away from said liquid metered dispensing chamber, wherein, when said cocking mechanism is pulled away from said chamber, said locking mechanism locks said cocking mechanism in said second position, draws said plunger at least partially out of said chamber and permits flow of liquid from said liquid storage means to said chamber, and wherein, when said locking mechanism is released, said spring biases said cocking mechanism and said plunger toward said chamber and dispenses a metered amount of liquid from said chamber; and, (e) a plunger stop located between said metered dosage dispensing chamber and said cocking mechanism to set a predetermined distance of travel of said plunger within said chamber, wherein said predetermined distance of travel of said plunger in said chamber is less than a distance of travel of said cocking mechanism from said first position to said second position.
