Abstract

A drain sanitizing article (9) for reducing microbiological activity in drain runoff areas having a housing (10), the housing having an inner wall (16) defining an inner opening (18) in the housing, an outer wall (12), and a bottom wall (14) defining a central cavity (15) in the housing (10), a tear strip (20) for destructibly removing the housing outer wall and a portion of the bottom wall (14), a handle (30) spanning the inner opening (18) of the housing (10) and joined to the inner wall (16) of said housing (10); and a chemical sanitizing agent (40).

Claims

1. A drain sanitizing article for dispensing a chemical sanitizing agent, capable of sanitizing running and standing drainage, said drain sanitizing article comprising an annular housing, a said housing having an inner wall, defining an opening in said housing for the passage of drainage over the article into the drain, an outer wall, and a bottom wall, said bottom wall cooperatively connecting said inner and outer walls and forming an inner cavity in said housing, and a hardened aqueous soluble chemical sanitizing agent, said chemical sanitizing agent contained within the inner cavity of said housing.

2. The drain sanitizing article of claim 1 additionally comprising means for destructibly removing a portion of said housing, said destructible removing means patterned into said housing wherein tearing said destructible removing means affects removal of a portion of said housing thereby exposing said chemical sanitizing agent.

3. The article of claim 1, wherein said outer wall and a portion of said lower wall are removed exposing said chemical sanitizing agent.

4. The drain sanitizing article of claim 1 wherein said housing additionally comprises a handle cooperatively connected to said housing inner wall and spanning the opening of said housing.

5. The drain sanitizing article of claim 1 wherein said housing additionally comprises a handle cooperatively connected to said housing outer wall and spanning the opening of said housing.

6. The drain sanitizing article of claim 2 wherein said housing additionally comprises a handle cooperatively connected to said housing inner wall and spanning the opening of said housing.

7. The drain sanitizing article of claim 2 wherein said housing additionally comprises a handle cooperatively connected to said housing outer wall and spanning the opening of said housing.

8. The drain sanitizing article of claim 1 wherein said housing is of one piece molded construction.

9. The drain sanitizing article of claim 2 wherein said housing, and said removing means are of one piece molded construction.

10. The drain sanitizing article of claims 4 or 5 wherein said housing, and said handle are of one piece molded construction.

11. The drain sanitizing article of claims 6 or 7 wherein said housing, removing means, and said handle are of one piece molded construction.

12. The drain sanitizing article of claim 10 wherein said one piece molded housing, removing means and handle comprises a polymeric material selected from the group consisting of polypropylene, polyethylene, and mixtures thereof.

13. The drain sanitizing article of claim 12 wherein said chemical sanitizing agent comprises an effective amount of sanitizer and an effective amount of hardener

14. The drain sanitizing article of claim 13 wherein said chemical sanitizing agent additionally comprises an effective amount of solubility modifier.

15. The drain sanitizing article of claim 13 wherein said chemical sanitizing agent additionally comprises an effective amount of dye wherein said dye indicates the intended environment of use of the chemical sanitizing agent and the continued presence of the sanitizing agent once installed.

26. The chemical sanitizing agent of claim 12 wherein said chemical sanitizing agent is a hardened pressed tablet conforming to the shape of said inner cavity.

16. A drain sanitizing article for dispensing a chemical sanitizing agent, capable of sanitizing running and standing drainage, said drain sanitizing article comprising an annular housing, said housing having an inner wall defining an opening in said housing for the passage of drainage over the article into the drain, an outer wall, and a bottom wall, said bottom wall cooperatively connecting said inner and outer walls and forming an inner cavity in said housing, said inner cavity for containing the sanitizing agent, a chemical sanitizing agent, said chemical sanitizing agent contained within said housing inner cavity, and means for destructibly removing a portion of said housing, said destructible removing means patterned into said housing wherein tearing said destructible removing means affects removal of a portion of said housing thereby exposing said chemical sanitizing agent.

17. The article of claim 16, wherein said outer wall and a portion of said lower wall are removed exposing said chemical sanitizing agent.

18. The drain sanitizing article of claim 16 wherein said housing additionally comprises a handle cooperatively connected to said housing inner wall and spanning the opening of said housing

19. The drain sanitizing article of claim 16 wherein said housing additionally comprises a handle cooperatively connected to said housing outer wall and spanning the opening of said housing.

20. The drain sanitizing article of claim 16 wherein said housing, and said removing means are of one piece molded construction.

21. The drain sanitizing article of claims 18 or 19 wherein said housing, removing means, and said handle are of one piece molded construction.

22. The drain sanitizing article of claim 21 wherein said one piece molded housing, removing means and handle comprises a polymeric material selected from the group consisting of polypropylene, polyethylene, and mixtures thereof.

23. The drain sanitizing article of claim 16 wherein said chemical sanitizing agent comprises an effective amount of sanitizer and an effective amount of hardener.

24. The drain sanitizing article of claim 23 wherein said chemical sanitizing agent additionally comprises an effective amount of solubility modifier.

25. The drain sanitizing article of claim 16 wherein said chemical sanitizing agent additionally comprises an effective amount of dye wherein said dye indicates the intended environment of use of the chemical sanitizing agent and the continued presence of the sanitizing agent once installed.

27. The drain sanitizing article of claim 16 wherein said chemical sanitizing agent is a hardened pressed tablet.

28. A method of using a drain sanitizing article for dispensing a chemical sanitizing agent, comprising the steps of:
