ABSTRACT:
An actuator assembly for the pumps or valves of small hand-held dispensers, especially aerosol containers, which are actuated by depression of an actuator member such as a button, includes a stationary component adapted to be mounted on a pressurized dispenser and a collar in screw-threaded engagement with the stationary component and surrounding an actuator member, which collar when tightened down on its screw prevents depression of the actuator member but when turned to slacken it back allows such movement. Preferably the collar moves downwards to tighten it and this movement may be translated into upward movement in opposition to depression of the actuator member by an arrangement of rocking levers.
