ABSTRACT:
A child-resistant liquid dispenser, such as a trigger sprayer, includes a dispenser body, a pump mechanism having a pump piston, and a trigger connected to the pump piston so that movement of the trigger effectuates movement of the pump piston. The pump mechanism is configured to draw liquid into an intake port of the dispenser body and discharge it through a discharge port upon reciprocating movement of the pump piston. The child-resistant liquid dispenser also includes a first locking mechanism which is engageable with the pump piston in a manner to prevent movement of the pump piston when in a locked position. The first locking mechanism is configured to permit normal movement of the pump piston when in an unlocked position. The child-resistant liquid dispenser further includes a second locking mechanism. The second locking mechanism is configured to releasably engage the first locking mechanism in a manner to releasably retain the first locking mechanism in its locked position.
