CHILD-RESISTANT NOZZLE FOR MANUAL PUMP DISPENSER

摘要

A child resistant lock for a trigger sprayer that comprises a dispenser body (10), a nozzle (22, 50), and a nozzle closure member (34, 60, 134). The dispenser body has a fluid discharge conduit (12, 114) for discharging fluid through the nozzle. The nozzle has a fluid passage (52, 130), communicating with the fluid discharge conduit and an orifice (56, 136) for discharging the fluid. The nozzle and the nozzle closure member are configured so that when in a closed position, the nozzle closure member blocks discharge of fluid from the nozzle and when in an open position, the nozzle closure member permits discharge of fluid from the nozzle. The child resistant lock and the nozzle closure member are configured to lock against movement of the nozzle closure member from its closed position. Two separate manual movements are needed to unlock the child resistant lock and move the closure member from its closed to its open position.
