Disposable urinal strainer with supporting and positioning means for holding a solid chemical material

Claim 2

A urinal deodorant chemical block support and positioning device in the form of a strainer comprising a large plate-like portion having a plurality of drainage openings distributed over its surface, said plate having an upper surface and a lower surface, an upstanding closed collar means substantially free of drainage holes integrally formed on said upper surface for receiving and supporting a deodorant chemical block, the interior of said collar having a closed floor, substantially free of drainage holes, said integral collar means projecting away from said upper surface, the collar and floor completing a closed supporting and positioning means for surrounding and protecting from erosion at least a portion of the base of said chemical block, and means also integrally formed on said upper surface intermediate the collar perimeter and projecting away from said upper surface at least as far as said collar projects away from said upper sUrface, the base of said deodorant chemical block having a peripheral contour which fits into said collar snugly enough to preclude erosion of the said block, and an opening in the base of said block which fits over said intermediate projection, whereby said block erodes from its outermost surface to approximately the level of said projecting means and then erodes centrally about said projecting means before eroding under said collar.

Claim 3

The device of claim 1 and loop means on the upper surface of said plate for engaging manipulating means which may be used to lift and manipulate said device.

Claim 4

The device of claim 1 and arm means formed integrally on said plate-like portion, said arm means having a section which enables said arm means to be rotated to project away from said plate, and said arm means being positioned to fit into a drainage opening in said urinal.

Claim 5

The device of claim 1 and first anchor means attached to the inner wall means of said urinal, and second anchor means on said plate for removably attaching said strainer to said anchor means.

Claim 6

The device of claim 4 wherein said anchor means comprises a magnetic material.

Claim 7

The device of claim 4 wherein said anchor means comprises a hook and fabric material.

Claim 8

The device of claim 4 wherein said anchor means includes a ball and socket swivel.

Claim 9

The device of claim 4 wherein said anchor means includes a suction cup.

Claim 10

A urinal deodorant solid chemical block support and positioning device in the form of a generally triangular strainer comprising a large plate-like portion having a plurality of drainage openings substantially uniformly distributed over its surface, said plate having an upper surface and a lower surface, elongated arm means formed integrally along one edge of said triangular plate-like portion with a weakened section near the center thereof, said arm means having oppositely disposed end sections which enable said arm means to be broken at the weakened center and then the two arms formed by said break to be rotated at the end sections to project away from said plate, said two arms being positioned to fit into drainage openings in a urinal, loop means on the upper surface of said plate for engaging manipulating means which may be used to lift and manipulate said device, closed collar means surrounding a floor member, said collar and floor being substantially free of drainage holes and integrally formed on the projecting away from said upper surface of said plate for receiving and supporting a deodorant chemical block, means also integrally formed on said upper surface of said plate at approximately the center of the collar perimeter and projecting away from said upper surface at least as far as said collar projects away from said upper surface, said deodorant chemical block having a generally dome shape with a peripheral contour at the base of said dome which fits into said collar snugly enough to support and to preclude erosion of said block, and an opening in the base of said dome-shaped block, said opening fitting over said projection, whereby said block erodes from the outward top of its dome-shaped surface to approximately the level of said projecting means and then erodes centrally about said projecting means before eroding under said collar.

Claim 11

A urinal deodorant solid chemical block support and positioning device in the form of a generally triangular strainer comprising a large plate-like portion having a plurality of drainage openings substantially uniformly distributed over its surface, said plate having an upper surface and a lower surface, elongated arm means formed integrally along one edge of said triangular plate-like portion with a weakened section near the center thereof, said arm means having oppositely disposed end sections which enable said arm means to be broken at the weakened center and then the two arms formed by said break to be rotated at the end sections to project away from said plate, said two arms being positioned to fit into drainage openings in a urinal, loop means on the upper surface of said plate for engaging manipulating means which may be used to lift and manipulate said device, closed collar means surrounding a floor member, said collar and floor being substantially free of drainage holes and integrally formed on the projecting away from said upper surface of said plate for receiving and supporting a deodorant chemical block, means also integrally formed on said upper surface of said plate at approximately the center of the collar perimeter and projecting away from said upper surface at least as far as said collar projects away from said upper surface, said deodorant chemical block having a generally dome shape with a peripheral contour at the base of said dome which fits into said collar snugly enough to support and to preclude erosion of said block, and an opening in the base of said dome-shaped block, said opening fitting over said projection, whereby said block erodes from the outward top of its dome-shaped surface to approximately the level of said projecting means and then erodes centrally about said projecting means before eroding under said collar.

Claim 12

The device of claim 9 wherein said collar is a circular cylinder, and a spider integrally formed in said plate inside said circular area, said projection being supported at the center of said spider.
