Abstract
A spray pump dispenser is described with a lever operated spray actuator mechanism, the lever being contouringly formed in a cap of the mechanism. A pair of guide posts on a plunger of the pump maintain proper orientation of the plunger during downward movement through cooperation with a pair of elongated ribs on an inner side wall of the cap. The aforementioned features prevent rotation of the plunger and control the spray direction as spray exits through a window in the cap.
