Abstract

The actuator includes a shroud adapted to be situated on an aerosol container over the stem and an actuation member mounted on and moveable within the shroud to depress the stem by the application of an external force applied to the top surface of the actuation member. The actuation member includes a nozzle and a conduit for connecting the stem and the nozzle. A hood is normally positioned to block the actuation member from being moved to depress the stem. A locking member normally intersects the path of movement of the hood to lock the hood in its blocking position. The locking member has two sections both of which must be simultaneously moved to a position remote from the path of hood movement such that the hood may be moved from its blocking position, allowing the actuation member to be moved to depress the stem.
