Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 161 words
A disposable paint strainer, comprising a sleeve of limp, flexible readily deformable material impermeable to paint and thin enough to be folded flat and secured by a rubber band when not in use for straining and a flexible, readily deformable, paint straining perforate element chemically bonded and secured continuously around its periphery to the inner surface of said sleeve with the portion of the sleeve above said perforate element defining with said perforate element a pocket for receiving the paint to be strained, said sleeve being formed for manual gripping together at its top and manual squeezing to force paint from said pocket out through the bottom end of said sleeve, said perforate element being positioned in spaced relation to the end of said sleeve opposite to said pocket so as to cause said sleeve to provide a skirt extending below said perforate element for keeping the hands of the user from contacting paint forced through said paint straining perforate element.
Claim 2
Dependent Claim 161 words
A disposable paint strainer, comprising a sleeve of limp, flexible readily deformable material impermeable to paint and thin enough to be folded flat and secured by a rubber band when not in use for straining and a flexible, readily deformable, paint straining perforate element chemically bonded and secured continuously around its periphery to the inner surface of said sleeve with the portion of the sleeve above said perforate element defining with said perforate element a pocket for receiving the paint to be strained, said sleeve being formed for manual gripping together at its top and manual squeezing to force paint from said pocket out through the bottom end of said sleeve, said perforate element being positioned in spaced relation to the end of said sleeve opposite to said pocket so as to cause said sleeve to provide a skirt extending below said perforate element for keeping the hands of the user from contacting paint forced through said paint straining perforate element.
Claim 3
Dependent Claim 17 words
Apparatus as described in claim 1 and wherein said sleeve is formed of thin, flexible sheet plastic.
Claim 4
Dependent Claim 18 words
Apparatus as described in claim 2 and wherein said flexible paint straining perforate element is formed of nylon.
Claim 5
Dependent Claim 19 words
Apparatus as described in claim 3 and wherein said flexible paint straining perforate element is formed of nylon mesh.
Claim 6
Dependent Claim 25 words
Apparatus as described in claim 4 and wherein the peripheral area of said perforate element is heat sealed to the inner surface of said sleeve.
Claim 7
Dependent Claim 25 words
Apparatus as described in claim 2 and wherein said sleeve is formed of polyethylene of from about 2 mils thickness to about 4 mils thickness.
Claim 8
Dependent Claim 28 words
Apparatus as described in claim 1 and wherein said sleeve is of tapered configuration wider at its end adjacent to said pocket and narrower at said perforate element.
Claim 9
Dependent Claim 22 words
Apparatus as described in claim 1 and wherein said sleeve narrows from its end adjacent to said pocket toward its opposite end.
