ABSTRACT:
An aerosol valve actuator with a discrete shell-like enclosure and a discrete, bottom mounted, actuating member with finger actuating pad. An opening with a perimeter, in the upper portion of the enclosure, is closed in non-actuated position by the finger pad which has a greater perimeter than the opening perimeter. The finger pad has an upper surface with a portion adjacent its perimeter which underlies and contacts the enclosure upper portion directly adjacent its opening leaving no discernable gap. The finger pad cannot be pushed upwardly through the opening to create a “smiling” effect. The actuating member is connected to the enclosure interior side wall, and has a nozzle outer end snap fit and extending into and filling an enclosure side wall product dispensing opening to prevent spray noise entering the enclosure and being intensified.
