Abstract

The present invention is directed to a non-splash urinal strainer with a perforated base pad and a deodorant canister fixed to the base pad. The deodorant canister includes a continuous outside wall fixed to a funnel shaped conduit that extends through the deodorant canister. The funnel shaped conduit has a large open target end for receiving an incoming urine stream and a drain end closed with a perforated grate positioned proximate the perforated base pad. Deodorant material is contained within a space provided between the continuous outside wall and the funnel shaped conduit.

Claims

1. A urinal strainer, comprising:

a) a perforated base pad;

b) a deodorant canister fixed to said perforated base pad; and

c) a conduit extending into said deodorant canister, said conduit fixed to said deodorant canister, said conduit having an open end to receive a urine stream and drain end positioned proximate said perforated base pad to discharge urine from said conduit.

2. The invention recited in claim 1, wherein:

a) said deodorant canister comprises an outside wall having one end fixed to said perforated base pad and an opposite end fixed to said open end of said conduit; and

b) said conduit comprises a tapered wall from said open end to said drain end so that said drain end is smaller than said open end, said drain end positioned above a top surface of said perforated base pad.

3. The invention recited in claim 2, wherein said open end is greater than ¼

inch in diameter.

4. The invention recited in claim 2, wherein said open end ranges between about 1 inch up to about 5 inches in diameter.

5. The invention recited in claim 2, wherein said open end is 2¾

inches in diameter.

6. The invention recited in claim 2, comprising a perforated grate attached to said drain end.

7. The invention recited in claim 4 comprising:

a chamber within said deodorant canister, said chamber defined by said outside wall, said conduit, said perforated grate, and said perforated base pad.

8. The invention recited in claim 7, wherein said chamber comprises:

a) a deodorant slot located between said outside wall and said conduit, said deodorant slot shaped to contain a deodorant material supported on said perforated base pad, and

b) a urine trap located between said perforated grate and said perforated base pad.

9. The invention recited in claim 8, comprising:

a plurality of apertures that extend through said outside wall into said deodorant slot.

10. The invention recited in claim 8, comprising:

a plurality of apertures that extend through said conduit into said deodorant slot.

11. The invention recited in claim 9 wherein said apertures are located within a lower half portion of said conduit.

12. The invention recited in claim 2, wherein said drain end is fixed to said perforated base pad.

13. The invention recited in claim 12 comprising:

a deodorant slot between said outside wall and said conduit, said deodorant slot shaped to contain a deodorant material supported on said perforated base pad.

14. The invention recited in claim 13, comprising:

a plurality of apertures that extend through said outside wall into said deodorant slot.

15. The invention recited in claim 13, comprising:

a plurality of apertures that extend through said conduit into said deodorant slot.

16. The invention recited in claim 8, comprising:

a rim-ring extending between and fixed to said opposite end of said outside wall and said open end of said conduit so that said deodorant slot is enlarged.

17. The invention recited in claim 13, comprising:

a rim-ring extending between and fixed to said opposite end of said outside wall and said open end of said conduit so that said deodorant slot is enlarged.

18. The invention recited in claim 1, wherein said conduit extends through said deodorant canister and through said perforated base pad to a location below a bottom surface of said perforated base pad.

19. The invention recited in claim 18, comprising:

a deodorant slot located between said outside wall and said conduit, said deodorant slot shaped to contain a deodorant material supported on said perforated base pad.

20. The invention recited in claim 19, comprising:

a rim-ring extending between and fixed to said opposite end of said outside wall and said open end of said conduit so that said deodorant slot is enlarged.

21. The invention recited in claim 19, comprising:

a plurality of apertures that extend through said outside wall into said deodorant slot.

22. The invention recited in claim 19, comprising:

a plurality of apertures that extend through said conduit into said deodorant slot.

23. The invention recited in claim 1, comprising:

indicia imprinted on a surface area within said conduit.

24. The invention recited in claim 1, wherein said perforated base pad comprises spaced apart slots extending through said base pad.

25. The invention recited in claim 1, wherein said perforated base pad comprises spaced apart circular holes extending through said base pad.

26. The invention recited in claim 1, wherein said perforated base pad comprises a mesh that provides openings through said base pad.

27. A non-splash urinal strainer, comprising:

a) a perforated base pad; and

b) a deodorant canister Including;

i. a continuous outside wall having a first end fixed to said perforated base pad;

ii. a funnel shaped conduit having open end fixed to a second end of said continuous outside wall, said funnel shaped conduit extending from said open end to a drain end positioned within said continuous outside wall proximate said perforated base pad;

iii. a perforated grate attached to said drain end of said conduit; and

iv. a deodorant material contained within a space provided between said continuous outside wall and said funnel shaped conduit portion within said continuous outside wall.

28. A method of eliminating splash back from a urinal fixture, comprising:

a) placing a urinal strainer over a waste drain provided in a bowl portion of the urinal fixture, said urinal strainer including;

i. a perforated base pad; and

ii. a deodorant canister fixed to said perforated base pad; and

iii. a funnel shaped conduit having an open end attached to said deodorant canister, said attached conduit extending into said deodorant canister to a drain end located proximate said perforated base pad.

b) directing a urine stream into said open end of said funnel shaped conduit;

c) containing urine splash back within said funnel shaped conduit;

d) discharging urine from said drain end onto said perforated base pad, and

e) draining said discharged urine through said perforated base pad and into the waste drain of the urinal fixture.

29. The method recited in claim 28, wherein said deodorant canister includes deodorant material contained within a space provided between a perforated continuous outside wall and a portion of said funnel shaped conduit that extends into said deodorant canister, the steps of the method further including:

a) flushing the urinal fixture with incoming flush water;

b) directing the flush water through said perforated continuous outside wall into said space containing deodorant material so that said perforated base, said deodorant canister, said funnel shaped conduit, and the urinal are cleansed with a deodorant containing flush water.

30. The method recited in claim 29 wherein said open end of said funnel shaped conduit is attached to said continuous outside wall and said funnel shaped conduit includes:
