Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 189 words
For use in straining a liquid paint and depositing the same within a reservoir container, an improved paint strainer comprising: an upwardly extending continuous closed wall support defining a plurality of facets formed into a closed faceted wall having upper and lower edges and defining an upper opening and a lower opening and a passage therebetween; means for removeably attaching said wall support to said reservoir container at said lower opening including a recessed groove defined in said lower edge of said closed wall support; and a strainer bag formed of a mesh material and defining a tapered cross-section and a closed end and an open end, said open end of said strainer bag extending the breadth of and being secured to said upper opening of said wall support in a removeable attachment and said closed and extending downwardly within said passage, said facets being connected in a hinged manner such that said wall support may be folded between a closed position in which said facets are collapsed upon each other and said passage is reduced and an open position in which the cross-section of said passage is maximum.
Claim 2
Dependent Claim 189 words
For use in straining a liquid paint and depositing the same within a reservoir container, an improved paint strainer comprising: an upwardly extending continuous closed wall support defining a plurality of facets formed into a closed faceted wall having upper and lower edges and defining an upper opening and a lower opening and a passage therebetween; means for removeably attaching said wall support to said reservoir container at said lower opening including a recessed groove defined in said lower edge of said closed wall support; and a strainer bag formed of a mesh material and defining a tapered cross-section and a closed end and an open end, said open end of said strainer bag extending the breadth of and being secured to said upper opening of said wall support in a removeable attachment and said closed and extending downwardly within said passage, said facets being connected in a hinged manner such that said wall support may be folded between a closed position in which said facets are collapsed upon each other and said passage is reduced and an open position in which the cross-section of said passage is maximum.
Claim 3
Dependent Claim 29 words
An improved paint strainer as set forth in claim 1 wherein said lower edges of said facets each define a plurality of notches extending upwardly from said lower edges.
Claim 4
Dependent Claim 18 words
An improved paint strainer as set forth in claim 2 wherein said wall support defines four equal facets.
Claim 5
Dependent Claim 20 words
An improved paint strainer as set forth in claim 3 wherein said faceted wall support is formed of cardboard material.
Claim 6
Dependent Claim 28 words
An improved paint strainer as set forth in claim 4 wherein said strainer bag overlaps a portion of said wall support and is secured thereto by an adhesive.
Claim 7
Dependent Claim 193 words
For use in straining a liquid paint and depositing the same within a reservoir container, having a generally cylindrical container edge, an improved paint strainer comprising: an upwardly extending continuous closed wall support defining a plurality of facets formed into a closed faceted wall having upper and lower edges and an upper opening and a lower opening and a passage therebetween, said facets being connected in a hinged manner such that said wall support may be folded between a closed position in which said facets are collapsed upon each other and said passage is reduced and an open position in which the cross section of said passage is maximum; means for removably attaching said wall support to said reservoir container at said lower opening; and a strainer bag formed of a mesh material and defining a closed end and an open end, said open end of said strainer bag extending the breadth of and being secured to said upper opening of said wall support and said closed end extending downwardly within said closed wall support passage, said strainer bag overlapping a portion of said wall support and being secured thereto by an adhesive.
Claim 8
Dependent Claim 193 words
For use in straining a liquid paint and depositing the same within a reservoir container, having a generally cylindrical container edge, an improved paint strainer comprising: an upwardly extending continuous closed wall support defining a plurality of facets formed into a closed faceted wall having upper and lower edges and an upper opening and a lower opening and a passage therebetween, said facets being connected in a hinged manner such that said wall support may be folded between a closed position in which said facets are collapsed upon each other and said passage is reduced and an open position in which the cross section of said passage is maximum; means for removably attaching said wall support to said reservoir container at said lower opening; and a strainer bag formed of a mesh material and defining a closed end and an open end, said open end of said strainer bag extending the breadth of and being secured to said upper opening of said wall support and said closed end extending downwardly within said closed wall support passage, said strainer bag overlapping a portion of said wall support and being secured thereto by an adhesive.
