an aerosol valve actuator with a top portion rotatable on a bottom portion . the entire top portion in one rotatable position is depressible vertically to actuate the valve . a click post and clicking rib provide a single click in each direction of rotation . flanges on top and bottom portions interact to stop rotation as soon as each click occurs . plastic springs interact with spring biasing members only when the top portion is in actuating position , and assure return of the actuator top portion to full upward position for rotation after actuation of even a short - stemmed valve . downwardly extending flexible connecting flanges connect the actuator top and bottom portions . the top portion has a lower periphery with a plurality of upwardly extending indentations to overlie lateral ribs in the lower portion in actuation position . the top and bottom portions have interfitting cylinders to stabilize the top portion and maintain verticality .
