ABSTRACT:
A spray confining aerosol dispensing device includes a pressurized aerosol container provided with an upwardly directed discharge tube coupled to a coaxial spray nozzle having a venturi shaped bore to effect the divergence of the spray. An axially movable spray confining tubular shield having an end discharge opening slightly greater than the spray pattern at such opening projects axially from the container, and axial depression of the shield effects the depression of the container valve actuator to open the valve. In one form the shield is alternatively movable to an extended operative position and to a contracted inoperative position with the container telescoping the shield and in another form the shield carries the venturi nozzle on a transverse wall so that the shield may be alternatively employed as a closure cap or a valve actuating spray confining shield.
