ABSTRACT:
This invention is a total release actuator having a structure that provides a time delay between the activation of an aerosol valve in an associated aerosol container and the discharge of product through the actuator. The structure effecting the time delay is an inflatable and movable component which slowly expands and moves upwardly when product is slowly introduced from the container to a closed chamber defined in part by the inflatable and movable component; the closed chamber being initially out of registry with a discharge conduit and orifice but which, after the chamber is slowly filled with product, moves into register with the said discharge conduit and orifice and product is discharged.
