Abstract: A door mounted actuating device for use with a spray container includes a frame for supporting the container and locating its spray nozzle at door top height, and an actuating mechanism having a pivotally mounted lever arm and a plunger assembly including a plunger rod movable to pivot the lever arm to depress the spray nozzle of the container causing a spray of fluid from the container both upon opening and closing of the door. The lever arm carries an adjustable member adjacent to the nozzle which is adjustable to vary the amount of spray. The plunger rod is adjustable to permit the actuating unit to spray only upon opening of the door, and a stop mechanism of the plunger assembly is adjustable to permit the actuating unit to spray only upon closing of the door.
