Abstract

A paint mask particularly adapted for masking corner areas of a demarcation zone to facilitate painting of an area of a workpiece disposed on the other side of the demarcation zone is formed of a thin, flexible sheet having opposite faces. The paint mask includes a first leg and a second leg that are generally rectangular in shape, and the legs intersect to form a right angle adapted for masking a corner and adjacent area. The bottom side of the paint mask which contacts the surface to be masked includes an adhesive for adhering the mask to the workpiece. The top side has release means for releasing stacked paint masks from each other.

Claims

1. A paint mask for masking a corner area adjacent workpieces to be painted, comprising:

a thin, flexible sheet having opposite bottom and top faces, said sheet being L-shaped and having first and second legs that are generally rectangular in shape and at right angles to one another;

said sheet includes an adhesive on said bottom face;

a plurality of said paint mask sheets are stacked upon one another to form a paint mask pad;

said top surface of each sheet includes release means and said adhesive on the bottom face of each paint mask sheet releasably engages the top face of the adjacent underlying paint mask sheet; and

,

a pair of said paint mask pads are oriented relative to each other and nestled together to provide a package in which the L-shaped sheets are in a square configuration.

2. A paint mask for masking a corner area adjacent workpieces to be painted, comprising:

a thin, flexible sheet having opposite bottom and top faces and at least a first and a second outer edge, said at least first and second outer edges intersecting at an angle of 90°

;

said sheet includes an adhesive disposed on said bottom face along the length of said at least first and second outer edges;

said sheet includes at least a first inner edge;

said adhesive extends from said at least first and second outer edges toward said at least first inner edge; and

,

said sheet includes a non-adhesive area on said bottom face.

3. A paint mask for masking a corner area adjacent workpieces to be painted, comprising:

a thin, flexible sheet having opposite bottom and top faces and at least a first and a second outer edge, said at least first and second outer edges intersecting at an angle of 90°

;

said sheet includes an adhesive disposed on said bottom face along the length of said at least first and second outer edges;

said sheet includes at least a first inner edge;

said adhesive extends from said at least first and second outer edges toward said at least first inner edge;

said sheet includes a non-adhesive area on said bottom face; and

,

said non-adhesive area extends from said adhesive to said at least first inner edge.

4. A paint mask for masking a corner area adjacent workpieces to be painted, comprising:

a sheet having opposite bottom and top faces and at least a first and a second outer edge, said at least first and second outer edges intersecting at an angle of 90°

;

said sheet includes an adhesive disposed on said bottom face in a band along a majority of said at least first and second outer edges;

said sheet includes at least a first inner edge;

said adhesive extends from said at least first and second outer edges toward said at least first inner edge; and

,

said sheet includes a non-adhesive area on said bottom face.

5. A paint mask for masking a corner area adjacent workpieces to be painted, comprising:

a sheet having opposite bottom and top faces and at least a first and a second outer edge, said at least first and second outer edges intersecting at an angle of 90°

;

said sheet includes an adhesive disposed on said bottom face in a band along a majority of said at least first and second outer edges;

said sheet includes at least a first inner edge;

said adhesive extends from said at least first and second outer edges toward said at least first inner edge;

said sheet includes a non-adhesive area on said bottom face; and

,

said non-adhesive area extends from said adhesive to said at least first inner edge.

6. A paint mask for masking a corner area adjacent workpieces to be painted, comprising:

a sheet having opposite bottom and top faces and at least a first and a second outer edge, said at least first and second outer edges intersecting at an angle of 90°

;

said sheet includes an adhesive disposed on said bottom face in a continuous band along a majority of said at least first and second outer edges;

said sheet includes at least a first inner edge;

said adhesive extends from said at least first and second outer edges toward said at least first inner edge; and

,

said sheet includes a non-adhesive area on said bottom face.

7. A paint mask for masking a corner area adjacent workpieces to be painted, comprising:

a sheet having opposite bottom and top faces and at least a first and a second outer edge, said at least first and second outer edges intersecting at an angle of 90°

;

said sheet includes an adhesive disposed on said bottom face in a continuous band along a majority of said at least first and second outer edges;

said sheet includes at least a first inner edge;

said adhesive extends from said at least first and second outer edges toward said at least first inner edge;

said sheet includes a non-adhesive area on said bottom face; and

,

said non-adhesive area extends from said adhesive to said at least first inner edge.
