Abstract

A child resistant assembly is disclosed comprising an actuator button having a terminal orifice connected through a valve stem to a valve for enabling discharge of the aerosol product from the terminal orifice upon opening the valve. An overcap is rotatably secured to the aerosol container and includes a finger actuator movably mounted relative to the overcap. A non-symmetrical surface is disposed on either the actuator button or the finger actuator for cooperation with an engaging surface on the other of the actuator button and the finger actuator. The engaging surface engages the non-symmetrical surface for transferring the finger movement of the operator to open the valve only upon a selected orientation of the finger actuator relative to the actuator button. The engaging surface fails to contact the non-symmetrical surface upon finger movement of the operator when the finger actuator is in a non-selected orientation relative to the actuator button.
