Abstract
A child-resistant liquid dispenser such as a trigger sprayer. The dispenser comprises a dispenser body, a nozzle, and a locking mechanism. The dispenser body has a nozzle receiving end and a discharge passage configured for discharging liquid through the nozzle receiving end. The-nozzle has a nozzle opening therein and is connected to the nozzle receiving end of the dispenser body. The nozzle is rotatable relative to the dispenser body about a nozzle axis X between open and closed positions. The nozzle and dispenser body are configured such that the nozzle opening is in fluid communication with the discharge passage of the dispenser body when the nozzle is in its open position to permit fluid to flow from the discharge passage and through the nozzle opening. They are further configured such that fluid communication between the nozzle opening and discharge passage is blocked when the nozzle is in its closed position to prevent fluid flow from the discharge passage and through the nozzle opening. The locking mechanism comprises a locking member adjacent the nozzle and dispenser body. The locking member is moveable along the nozzle axis X between locking and unlocking positions. The locking mechanism, dispenser body, and nozzle are configured to prevent rotational movement of the nozzle from its closed position to its open position when the locking member is in its locking position and to allow rotational movement of the nozzle between its closed and open positions when the locking member is in its unlocking position.
