Actuator for an aerosol container
An actuator for an aerosol container having a valve with a projecting valve stem includes an actuator button having an outlet for coupling to the valve stem. A crossbar is disposed between the container and the actuator button. The crossbar is movable with respect to the valve stem between at least a first position blocking depression of the actuator button with respect to the valve stem and a second position permitting depression of the actuator button with respect to the valve stem. The crossbar preferably can be moved from either side of the actuator, and one or more springs preferably are carried by the crossbar for engaging the container and biasing the crossbar to the first or blocking position.
1. An actuator for an aerosol container having a valve with a projecting valve stem, said actuator including:
an actuator button having an outlet for coupling to the valve stem, and
a crossbar for disposition between the container and said actuator button, said crossbar being movable with respect to the valve stem between at least a center first position blocking depression of said actuator button with respect to said valve stem and spaced second positions on opposite sides of said first position permitting depression of said actuator button with respect to said valve stem,
wherein
said actuator button has an internal rib and said crossbar has a release tab that blocks said internal rib in said first position of said crossbar and is spaced from said rib in said second positions of said crossbar,
said rib has a pair of side notches facing in opposite directions,
said crossbar has a pair of laterally spaced lock tabs on opposite sides of said release tab, and
said crossbar is movable between said center first position, said spaced second positions, and spaced third positions on opposite sides of said second positions at which one of said lock tabs is received in a corresponding notch to lock said actuator button in a depressed position.
2. The actuator set forth in claim 1 wherein said crossbar has a center opening for receipt over the valve stem, and said release tab and said lock tabs extend laterally with respect to said center opening.
3. The actuator set forth in claim 2 including springs for engaging the container and biasing said crossbar to said center first position.
4. The actuator set forth in claim 3 wherein said springs are integrally formed with said crossbar.
5. The actuator set forth in claim 4 wherein said crossbar includes integrally formed finger pads on opposed ends of said crossbar.
6. The actuator set forth in claim 1 including at least one spring for engaging the container to bias said crossbar toward said center first position.
7. The actuator set forth in claim 6 wherein said at least one spring is integral with said crossbar.
8. The actuator set forth in claim 1 including a lower housing for surrounding the valve stem and an upper housing receivable on said lower housing for enclosing said crossbar, said crossbar extending through openings on opposed sides of said upper housing.
9. The actuator set forth in claim 8 wherein said actuator button is integrally coupled to said upper housing by a pivot hinge.
10. The actuator set forth in claim 9 wherein said lower housing has upstanding legs that partially block said openings in said upper housing.
