Abstract: A continuous dispensing actuator assembly having a mounting cup, an actuator, an overcap and a locking adaptor provides for automatic discharge of the contents of a pressurized container. The mounting cup secures to an open end of the pressurized container and has a valve biased into a normally extended closed position with an extending valve stem. The overcap includes a base portion affixed to the mounting cup, an orientation tab slidably residing within the slot in the actuator to prevent rotational movement of the actuator, a locking mechanism and a slot in the locking mechanism sized to allow passage of the actuator cam post.
