Abstract

The present invention relates to an improved urinal block composition comprised of fluid-soluble chemical components, and an improved dispenser to be used with that urinal block. Specifically, the present invention is directed to a unique combination of chemicals that when blended together to form a urinal block composition yields a stable product that is effective at deodorizing and cleaning urinals and toilets. The improvement of using an acid stable protease enzyme with the other fluid-soluble chemical components of the urinal block composition provides the advantage of dissolving and otherwise neutralizing odors associated with urinals and toilets. The urinal block is retained in and dispensable from a disposable dispenser assembly 10 for use in urinals and toilets. The urinal block is protected from direct action of urine by a retention cup 18 which retains the chemical block composition 32 in position, and the inner hollow area 12 of the dispenser 10 allows the dispenser 10 to fit around strainers found in urinals. The dispenser has a perforated flange 20 that supports the hollow area 12 and retention cup 18 within the urinal, while also allowing for effective drainage.

Claims

1. A urine deodorant chemical dispenser adapted to be placed over the urine and flush water drain opening on the bottom of a urinal for dispensing fluid-soluble chemicals, said dispenser comprising a dispenser body having:

a. an inner hollow portion adapted to be placed over said drain opening in the bottom of said urinal and having at least one opening at the top thereof for aeration and for reception of said urine and/or flush water to be directed to said drain opening; and

b. a urinal deodorant chemical retention cup portion surrounding said hollow portion and defining a vertically extending annular chamber for holding a solid body of a water-soluble deodorant chemical, said annular chamber being defined by vertically extending inner and outer walls and a top wall, which walls prevent said chemical body from being contacted by urine and flush water at the sides and top of said chamber, the bottom of said annular chamber being open and exposed so that said solid chemical body is contacted by a momentary build-up of flush water around said drain opening; and

c. a flange adapted to rest upon the bottom of said urinal and to space the bottom surface of the solid body of deodorant chemical in the open bottom of said annular chamber from the flange and the floor of the urinal, said flange extending outwardly from said outer wall of said retention cup portion, said body having at the bottom portion thereof apertures therein for directing said urine and flush water towards the dispensing opening and beneath the open bottom of said annular chamber of said retention portion where flush water builds up to contact the bottom of said solid body of deodorant chemical.

2. The dispenser of claim 1 wherein the flange of said dispensed body is substantially oval shaped.

3. The dispenser of claim 1 wherein the configuration of said hollow portion of said dispenser body allows said dispenser assembly to fit over a strainer located over said urinal dispensing opening.

4. The dispenser assembly of claim 1 wherein said retention cup portion is a transparent material.

5. The dispenser of claim 1 wherein said hollow portion, said retention cup portion and said perforated flange of said dispenser body are molded in one piece.

6. The dispenser assembly of claim 1 wherein said retention cup portion includes means for retaining said fluid-soluble chemical in a ready-for-use position within said cup portion.

7. The dispenser of claim 1 combined with a solid body of said deodorant chemical in said annular chamber with the exposed bottom portion thereof spaced above said flange.
