Abstract

The aerosol actuator includes a shroud. An actuation member situated within the shroud has a stem bore pocket adapted to receive the valve stem of the aerosol container. In high speed production, entrance of the stem into the pocket as the shroud is mounted on the aerosol container is facilitated by providing the pocket with a plurality of inwardly extending compressible ribs and a tab extending from the shroud which stabilizes the actuation member within the shroud. The tab is pivoted out of the path of movement of the actuation member upon initial depression of the actuation member by the user. To prevent accidental depression of the actuation member by a top load, the shroud wall is extended above the plane of the surface of the actuation member.
