Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
196 words
A device for use in controlling pests on a growing plant, comprising: a cap having an interior chamber with an open bottom, a torroid of pesticide disposed in said chamber, first and second apertured closure members disposed across the bottom of said cap with said first closure member superimposed on said second and each having apertures adapted to register with one another upon relative rotation, a stem for supporting said cap on a surface adjacent said plant with said open bottom spaced from said surface, said stem having an upper shoulder in said chamber supporting said toroid and a pin projecting upwardly through said toroid and being upset downwardly toward said cap for rotatably mounting said cap to said stem, said stem also having a lower shoulder engaging the underside of said second closure member, means securing said first closure member to said cap for rotation therewith, and means securing said second closure member to said stem so that rotation of said cap relative to said stem causes the apertures in said closure members to register, thereby affording access of ambient air to said chamber for contacting said pesticide subsequently to distribute it about the plant.
Claim 2
Independent Claim
196 words
A device for use in controlling pests on a growing plant, comprising: a cap having an interior chamber with an open bottom, a torroid of pesticide disposed in said chamber, first and second apertured closure members disposed across the bottom of said cap with said first closure member superimposed on said second and each having apertures adapted to register with one another upon relative rotation, a stem for supporting said cap on a surface adjacent said plant with said open bottom spaced from said surface, said stem having an upper shoulder in said chamber supporting said toroid and a pin projecting upwardly through said toroid and being upset downwardly toward said cap for rotatably mounting said cap to said stem, said stem also having a lower shoulder engaging the underside of said second closure member, means securing said first closure member to said cap for rotation therewith, and means securing said second closure member to said stem so that rotation of said cap relative to said stem causes the apertures in said closure members to register, thereby affording access of ambient air to said chamber for contacting said pesticide subsequently to distribute it about the plant.
Claim 3
Dependent Claim
46 words
A device according to claim 1 wherein said first closure member securing means includes engaged flats on said cap and said first closure member, and said second closure member securing means includes a key projecting upwardly from said intermediate shoulder and through said second closure member.
Claim 4
Dependent Claim
35 words
A device according to claim 2 including stop means on said first closure member for cooperating with said key to stop relative movement of said closure members when their apertures are aligned with one another.
Claim 5
Dependent Claim
36 words
A device according to claim 3 wherein said stem has a lower shoulder adapted to engage said surface and a tip portion depending below said lower shoulder for penetrating the surface to mount the stem upright.
Claim 6
Dependent Claim
36 words
A device according to claim 3 wherein said stem has a lower shoulder, and including a clip adapted to hook over the edge of a plant pot, and means connecting said clip to said stem shoulder.
