Abstract
A pump sprayer having a lock slidably mounted on the plunger head for locking the pump sprayer against reciprocation within a sleeve on a closure provided for mounting the sprayer to a container. The lock has a body with a rear portion, a cap portion, a pair of arms with flanges and a stop projection. The arms define springs in one embodiment for engaging a portion of the pump sprayer and providing a restoring force that enables the locking mechanism to be self-resetting to a locked position. The body is capable of being moved by the operator of the pump sprayer within the peripheral outline of the plunger head. When in a forward position, the lower edge of the rear portion of the lock is disengaged from an upper edge of the sleeve placing the pump sprayer in an unlocked position. When the projection is released and the plunger head is reciprocatingly restored to an upright position, the lower edge of the rear portion automatically engages the upper edge of the sleeve of the pump sprayer preventing plunger head reciprocation and the biasing means automatically forces the lock into a rearward, locked position on the plunger head thus rendering the pump sprayer self-resetting and child-resistant. In another embodiment the lock is a shipper lock which does not reset from its locked position.
