ABSTRACT:
A manually actuated, pressure build-up pump sprayer that is to be interconnected with a container for atomizing and spraying a liquid from the container. The pump sprayer includes air-tight seals and valves which are opened and closed at different portions of the stroke cycle, such that trapped air may be quickly compressed and efficiently blown from the poppet into the container and liquid from the container drawn into the poppet and sprayed from the spray head. Thus, the sprayer may be easily primed after only a few stroke cycles. The sprayer is characterized by a relatively reduced number of parts and manufacturing cost as well as the ability to prevent leakage and allow spraying of the liquid in the event that the container is tipped or turned over.
