Estimating the term…
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.
An aerosol actuator for use with a container of pressurized fluid of the type having a valve with a stem depressible to release the contents of the container, said actuator comprising a shroud adapted to be situated on the container over the stern, an actuation member situated within said shroud comprising a stem bore pocket adapted to receive the valve stem, said actuation member being movable relative to said shroud between a first position wherein the valve stem is not depressed and a second position wherein the valve stem is depressed to release the contents of the container, said actuation member including a nozzle with an outlet port and a channel connecting the valve stem and said nozzle, said stem bore pocket having an axis parallel to an interior surface of the stem bore pocket, and a plurality of ribs extending from said interior surface of said stem bore pocket along the direction of said axis to facilitate entrance of the stern into said stern bore pocket, wherein said ribs comprise inclined surfaces proximate the entrance of said stem bore pocket, are circumferentially arranged around said interior surface of said stem bore pocket, are formed of compressible or resilient material, have tapered outer edges and function to funnel the valve stem into said stem bore pocket, the ribs guide the end of the valve stem into the stem bore pocket by aligning the stem bore pocket with the valve stem as the actuator is mounted on the container.
An aerosol actuator for use with a container of pressurized fluid of the type having a valve with a stem depressible to release the contents of the container, said actuator comprising a shroud adapted to be situated on the container over the stem, an actuation member mounted to said shroud for movement between a first position wherein the valve stem is not depressed and a second position wherein the valve stem is depressed to release the contents of the container, said actuation member including a nozzle with an outlet port and a channel connecting said valve stem and said nozzle, and a tab extending from said shroud toward the path of movement of said actuation member, said tab being moved from an active position intersecting said path of movement of said actuation member to a passive position remote from the path of movement of said actuation member only the first time said actuation member is moved from said first position to said second position, wherein said tab thereafter permanently remains in said passive position remote from the path of movement of said actuation member, wherein said actuation member comprises a stem bore pocket and said tab, in said active position stabilizes said actuation member such that said stem bore pocket is aligned with the valve stem.
