Abstract
An actuator for mounting on the end of a pressurized container from which a centrally located, depressible valve stem protrudes. The actuator is characterized by a base surrounding the axis defined by the stem, an actuator tab hinged to the base and extending across the axis to terminate in a finger-depressible free end, a stem-engaging member on the tab which forms with the tab a passageway terminating in a discharge orifice, and a disabling member on the base adjacent the free end and moveable between a locked position blocking tab depression and an unlocked non-blocking position. Other preferred features relate to a hinge attachment of the disabling member to the base, a snappingly engageable catch on the disabling member to engage the tab, a cam on the disabling member to direct the tab upwardly as the disabling member is moved to the locked position, a ledge at the tab free end blocking access to the catch means, and a one-piece construction of the entire structure.
