A method for filling an aerosol container with propellant, wherein an enlarged button actuator (button having a diameter base of at least fifteen millimeters) having a discharge orifice communication with a socket for receiving the hollow valve stem of an aerosol valve, an annular wall radially outward of the socket for sealing on a pedestal of a valve mounting cup and a sealing surface on the outer wall for mating with a propellant filling head, and at least one conduit communicating a chamber defined, in part, by the annular wall sealing on the pedestal and a chamber defined by the interior of the filling head and the outer surface of the button is employed. The method provides a system for propellant filling of the container with the button on the stem of the associated valve coupled to the aerosol container opening. The method steps involve securing an aerosol valve to the can opening, mounting the enlarged actuator button on the valve stem of the aerosol valve, advancing a filling head to a sealing relation to the outside of the enlarged button actuator and concomitantly sealing the annular wall to the pedestal, and introducing pressurized propellant through the filling head.
