Abstract
An actuator comprising an exterior housing having an outer wall with a product discharge outlet formed therein. The exterior housing also has a central post supporting a bore which communicates with both a product inlet and the product discharge outlet to facilitate the dispensing of product via the actuator. A base of the exterior housing has an annular skirt portion provided for engagement with a mounting cup during a button-on-filling process. At least a base of the skirt portion, provided for engaging with a mounting cup during a button-on-filling process, is formed from a softer material than a remainder of the actuator to facilitate sufficient deformation of the base of the skirt portion, during the button-on-filling process, to provide an adequate seal with a top surface of the mounting cup. The remainder of the actuator is preferably manufactured from one of nylon, polypropylene and acetal while the annular skirt portion is manufactured from one of a low density polyethylene, a high density polyethylene and a thermoplastic rubber.
