Abstract

A masking device to prevent over-spray when using an aerosol can to apply aerosols to a work surface. The device includes a horizontal channel structure, the back end of which is essentially open and serves as an insertion point for an aerosol nozzle feed tube from an aerosol can, while the front end serves as an attachment seat for a masking unit. The back end of the horizontal channel is open, providing the user access to the aerosol nozzle in order to actuate the aerosol nozzle with a finger, whereby an aerosol is propelled forward into a masking unit. The masking unit has a small orifice creating a planar opening at the back, and a large orifice creating a generally planar opening at the front The masking unit is essentially hollow, providing the ability to contain an aerosol, the large orifice serving as a mask against a target surface. The masking unit has an observation cut out covered with a transparent film, a vent to exhaust excess pressure and aerosol, and raised beads radiating from the small orifice to the large orifice, which serve as excess aerosol accumulators.

Claims

7. An aerosol spray masking device comprising:

a substantially hollow masking unit for containing an aerosol, said masking unit having a front and a back, a first orifice defining a rear opening and a second orifice defining a front opening, said first orifice and second orifice sharing an axis, a top and a bottom, an interior surface and an exterior surface, a cross sectional opening in the top of said masking unit, and at least one vent for exhaust of pressure and aerosol;

said rear opening having an annular retention ring extending in a planar fashion, perpendicular to said axis,

a plurality of raised product accumulators radiating from said first orifice to said second orifice on said interior surface of said masking unit;

a transparent film covering said cross sectional opening in said masking unit;

a horizontal channel having a back end, a front end and a bottom, a left side and a right side;

an attachment means on said front of said horizontal channel having retention tabs medially protruding from said left side and said right side; and

,

an aerosol dispersion nozzle feed tube aperture in said bottom of said horizontal channel for insertion of an aerosol dispersion nozzle feed tube.

10. The aerosol spray masking device of claim 7, wherein said vent comprises a plurality of slits in said masking unit.

11. The aerosol spray masking device of claim 7, wherein at least one said vent is located proximally to said large orifice of said masking unit.

12. The aerosol spray masking device of claim 7, wherein said horizontal channel has an open back end, providing access for a user'"'"'s finger to actuate an aerosol dispersion nozzle attached to said aerosol dispersion nozzle feed tube.

8-1. The aerosol spray masking device of claim 8, wherein said large orifice of said masking unit has a raised bead defining an interior rim of said large orifice, providing an accumulation reservoir for excess aerosol.
