Abstract

A trigger actuated liquid sprayer, including a pump body, a discharge nozzle mounted on a forward end of the body for manual rotation about a central axis thereof between discharge open and closed positions, and a trigger lever movably mounted to the body for operating a pumping mechanism upon actuation thereof. A trigger cover may be mounted on the sprayer and overlie a front face of the trigger lever in a first position for immobilizing trigger lever actuation. The trigger cover may be rotatable to a second position from the first position for exposing the front face for facilitating a grasp of the trigger lever for manual actuation thereof for operating the pumping mechanism. The trigger cover may be latched with the trigger lever in the first position to prevent rotation of the trigger cover from the first position to thereby render the sprayer child-resistant.
