An actuator for facilitating filling of an aerosol contain by a button-on-filling process, the actuator comprising an exterior housing having an outer wall with a product discharge outlet formed therein. The exterior housing further having central post supporting an internal bore which establishes fluid communication between a product inlet and the product discharge outlet to facilitate dispensing an aerosol product via the actuator. At least two spaced apart reinforcement ribs are provided for interconnecting the exterior housing with the central post and thereby define at least two compartments where any remaining filling component may collect. A base of the exterior housing has an annular skirt portion which facilitates sealing engagement with a pedestal portion of a mounting cup during a filling operation. A longitudinal passageway communicates with each formed compartment, of the actuator, to facilitate complete purging of any remaining filling component, during a purging step of the button-on-filling process, from each formed compartment to essentially prevent the discharge of any remaining filling component into a surrounding production facility environment.
