Abstract
A fluid dispenser having a child-resistant nozzle assembly requiring a three-step manipulation for the rotation of the nozzle cap about a longitudinal axis thereof between discharge ON and discharge OFF positions. The nozzle cap has at least one stop shoulder with which a manually depressable spring tab on the dispenser body engages to lock the cap in an OFF position against cap rotation. A nozzle cover surrounds the cap and is freely rotatable about the longitudinal axis of the cap and along that axis, the cap and the cover having engaging portions such that when engaged with the spring tab depressed, the cap can be rotated from its OFF position.
