Abstract
An actuator assembly for an aerosol container containing a product to be dispensed. The actuator assembly comprises a base having a through bore extending therethrough and a mechanism for securing the base member to a mounting cup of the aerosol container. An actuator is supported in the through bore of the base and is slidable along a longitudinal axis thereof via a pair of mating bearing and guide surfaces. The through bore contains a pair of opposed stop members which permanently retain the actuator within the through bore. The actuator is allowed to slide within the through bore, during installation of the actuator assembly onto an aerosol container, to prevent the actuator from sufficiently engaging with or depressing the valve stem so that inadvertent discharge of the product contents is prevented until actual use of the aerosol container by the end user.
