A total release actuator for use with an aerosol can having a chime, a dome, and a valve having a valve stem. The actuator has an actuator body with a lower margin defining a skirt rim that attaches to the aerosol can and a central well having a generally horizontal well floor that has a trigger port extending therethrough. The actuator has a trigger that is hingedly attached to the actuator body, preferably at its front end to the front end of the trigger port. The trigger swings downwardly when it is depressed. The trigger extends across the valve stem and includes a downwardly open stem socket that receives the valve stem. The stem socket communicates with a discharge nozzle. The trigger, when moved downwardly, activates the valve, releasing the contents of the can through the discharge nozzle via the stem socket. A latch is attached to preferably each side of the trigger port, extending laterally under the trigger. The latch is elastically deformable, allowing the trigger to pass as it is depressed downwardly and then springing back over the trigger to retain it in the depressed, valve-activating position, allowing can contents to discharge. By this procedure, a user can release the entire contents of the aerosol can without the user's having to continue to depress the trigger. A method is described of discharging the contents of an aerosol can by use of such an actuator. |
