ABSTRACT:
An apparatus is disclosed for an improved manually actuated pump for dispensing a liquid within a container comprising a pump body having an internal pump cylinder secured to the container. A piston is slidably disposed within the internal pump cylinder of the pump body with a pump stem having a stem end extending external the pump body. The stem end supports an actuator having a nozzle communicating with an internal stem passage of the pump stem for discharging the liquid from the container through the nozzle. A lock comprises a projection extending radially outward from the pump stem and an overhang extending radially inwardly relative to the internal pump cylinder of the pump body for preventing movement of the actuator in either an extended position or a retracted position upon rotation of the pump stem.
