Abstract

The present invention is a continuous action liquid dispenser which includes a main housing with a housing outlet and a housing inlet which is adapted to receive a pumping rod. It also includes a pumping rod which is at least partially located within said main housing so as to be vertically reciprocally movable therein. The rod has a predetermined shape, volume and displacement with a first, upward position and a second, downward position and includes a valve seat and one-way valve which permits liquid material to pass therethrough in a relative direction toward the outlet, but not toward the inlet. There is also an inlet valve seat and valve connected to the inlet of the main housing and arranged so as to permit flow of fluid material into, but not out of, the main housing inlet. There is a top housing connected to the upper end of the main housing adapted for reciprocal movement with an activator. There is an outlet channel and dispenser nozzle, as well as a spring mechanism which biases the activator and pumping rod to their first position.
