Abstract
Abstract A child-resistant nozzle assembly for a fluid dispenser has an external anti-rotative stop, and the dispenser body has a spring-biased tab abutting the stop in an off position of the nozzle at which the discharge passage is closed for locking the cap against rotation from such off position. The tab is flexed outwardly away from the stop to permit cap rotation for opening the spray discharge.
