Abstract
The nozzle cap of the dispenser is rotatably supported at the nozzle end of the dispenser body for rotation between ON and OFF positions. At least one locking member is integrally connected to the body to form a flexible connector which permits rocking movement of the locking member. The locking member extends laterally from one side of the body so as to be in full view when the dispenser is held in the hand of a user. The locking member fits within a recess formed in the nozzle cap to lock the nozzle cap against rotation when the nozzle cap is in OFF position. Inward pressure on the locking member releases it from the recess to permit rotation of the nozzle cap to ON position. The nozzle cap includes a discharge passage in communication with a discharge opening and may also include one or more additional passages which provide communication between a portion of the nozzle cap near the discharge opening and ambient air to prevent a child from sucking contents of the container through the discharge opening.
