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.

[ I claim:] [23.] A total release actuator for use with an aerosol can having a chime, a dome, and a valve having a valve stem, the actuator comprising:a. an actuator body havingi. a peripheral skirt extending downwardly to a lower margin of the peripheral skirt defining a skirt rim, the skirt rim being adapted to engage the chime of the aerosol can,ii. a central well having a generally horizontal well floor, the well floor having a trigger port extending therethrough, the trigger port having a front end, a back end, and opposed sides,b. a longitudinally extended trigger having a front end, a back end, and sides, the triggeri. being attached at one of its front and back ends to the corresponding end of the trigger port by a hinge that allows the end of the trigger that is remote from the hinge to swing downwardly when the trigger is depressed, the trigger extending from the hinge across the valve stem when the actuator is in place on the aerosol can, andii. including a downwardly open stem socket that is adapted to receive the valve stem, the stem socket being in fluid communication with a discharge nozzle, the trigger, when moved downwardly, activating the valve by exerting pressure on the valve stem, releasing the contents of the can through the discharge nozzle via the stem socket, andc. an elastically deformable latch attached to one of a side of the trigger port and a side of the trigger and adapted to engage the other of the side of the trigger port and the side of the trigger when the trigger is in a depressed, valve-activating position to retain the trigger in that position, rein the peripheral skirt extends upwardly above the level of the well floor, and the central well has a well wall that extends upwardly from the margins of the well floor and is joined to the upper margin of the peripheral skirt to form a double-walled, hollow bracing structure, the bracing structure, well floor, and chime-engaging skirt rim combining to increase the resistance of the actuator body to lateral flexing.
