Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
140 words
In a crawling insect trap comprising an upper surface, a bottom surface and side walls, having an opening in said upper surface leading to the interior of said crawling insect trap, a layer of glue within said trap covering at least a portion of said bottom surface, and an inwardly sloping ramp, having an angle of inclination, as measured from a plane parallel to said bottom surface, of from about 5° to 10°, coterminous with an inwardly sloping decline having a final angle of elevation, as measured from a plane parallel to said bottom surface, of from 10° to 90°, covered with at least a particulate material, which will come loose when walked upon by a crawling insect causing the insect to fall through said opening into said trap and to be held fast therein by said layer of glue.
Claim 2
Dependent Claim
140 words
In a crawling insect trap comprising an upper surface, a bottom surface and side walls, having an opening in said upper surface leading to the interior of said crawling insect trap, a layer of glue within said trap covering at least a portion of said bottom surface, and an inwardly sloping ramp, having an angle of inclination, as measured from a plane parallel to said bottom surface, of from about 5° to 10°, coterminous with an inwardly sloping decline having a final angle of elevation, as measured from a plane parallel to said bottom surface, of from 10° to 90°, covered with at least a particulate material, which will come loose when walked upon by a crawling insect causing the insect to fall through said opening into said trap and to be held fast therein by said layer of glue.
Claim 3
Dependent Claim
19 words
The crawling insect trap of claim 1, wherein the particular material and an attractant cover the inwardly sloping decline.
Claim 4
Dependent Claim
43 words
The crawling insect trap of claim 2, wherein the inwardly sloping decine has an outer zone and an inner zone, said outer zone is covered with a layer of the loosely adhering particulate material and said inner zone is covered with the attractant.
Claim 5
Dependent Claim
18 words
The crawling insect trap of claim 1, wherein the final angle of elevation is from 45° to 90°.
Claim 6
Dependent Claim
20 words
The crawling insect trap of claim 4, wherein the size of the particulate material is from 1 to 1000 microns.
Claim 7
Dependent Claim
20 words
The crawling insect trap of claim 5, wherein the size of the particulate material is from 100 to 300 microns.
Claim 8
Dependent Claim
19 words
The crawling insect trap of claim 4, wherein the particulate material is tetrafluoroethylene resin or a ground pyrophyllite-aluminum silicate.
Claim 9
Dependent Claim
143 words
In an ant trap comprising an upper surface, a bottom surface and side walls, having an opening in said upper surface leading to the interior of said crawling insect trap, a layer of glue within said trap covering at least a portion of said bottom surface, and an inwardly sloping ramp, having an angle of elevation, as measured from a plane parallel to said bottom surface, of from about 5° to 10°, coterminous with an inwardly sloping decline with a final angle of elevation, as measured from a plane parallel to said bottom surface, of from 10° to 90°, covered with at least particulate tetrafluoroethylene resin or a ground pyrophyllite-aluminum silicate, which will come loose when walked upon by an ant causing the ant to fall through said opening into said trap and to be held fast therein by said layer of glue.
Claim 10
Dependent Claim
143 words
In an ant trap comprising an upper surface, a bottom surface and side walls, having an opening in said upper surface leading to the interior of said crawling insect trap, a layer of glue within said trap covering at least a portion of said bottom surface, and an inwardly sloping ramp, having an angle of elevation, as measured from a plane parallel to said bottom surface, of from about 5° to 10°, coterminous with an inwardly sloping decline with a final angle of elevation, as measured from a plane parallel to said bottom surface, of from 10° to 90°, covered with at least particulate tetrafluoroethylene resin or a ground pyrophyllite-aluminum silicate, which will come loose when walked upon by an ant causing the ant to fall through said opening into said trap and to be held fast therein by said layer of glue.
