Abstract

A urinal outlet device including a hollow perforated cage for retaining one or more effluent treatment blocks within the cage. The cage is provided with spacing means, in the form of spikes on the inside of the cage for holding the blocks at a spaced distance from an inside surface of the cage. The cage, spacing means, are dimensioned, shaped and positioned relative to the blocks and an outlet flow of effluent from the urinal so that, in use of the device, the blocks are spaced from a surface of the urinal whilst enabling the one or more blocks to be exposed to the flow of urine. Where the urinal is a water flushable urinal, the blocks are held substantially out of the main flow of flushing water flowing to the outlet of the urinal to prolong the life of the blocks without impairing their ability to disinfect and deodorise the urinal.

Claims

1. A urinal outlet device comprising a hollow perforated cage for retaining one or more effluent treatment blocks within the cage, wherein the cage is provided with spacing means on the inside of the cage for holding the one or more blocks at a spaced distance from an inside surface of the cage, said cage and the spacing means being dimensioned, shaped and positioned relative to the one or more blocks and an outlet flow of effluent from the urinal so that in use of the device, the blocks are spaced from a surface of the urinal whilst enabling the one or more blocks to be exposed to the flow of urine.

2. A urinal according to claim 1 wherein the outer surface of the cage has recesses that provide facets on which the cage rests when placed in an outlet of a urinal.

3. A urinal according to claim 1 wherein the urinal is a water flushable urinal and the said cage, spacing means and recesses are dimensioned, shaped and positioned relative to the one or more blocks and an outlet flow of effluent from the urinal so that, in use of the device, the blocks are held substantially out of the main flow of flushing water flowing to the outlet of the urinal whilst enabling the one or more blocks to be exposed to the flow of urine.

4. A device according to claim 1 wherein the spacing means comprise spikes that project radially inwards from the inside surface of the cage on to which the blocks are impaled.

5. A device according to claim 1, wherein the cage comprises two interconnected parts.

6. A device according to claim 1 wherein the cage is of generally spherical shape.

7. A device according to claim 1 wherein the perforations of the cage comprise a plurality of first openings spaced around the perimeter of the cage.

8. A device according to claim 6 the perforations comprise a plurality of second openings that are smaller than the first openings spaced around the perimeter of the cage.

9. A device according to claim 1 wherein the cage is selected from a cube shape, a hemispherical shape with a flat base, an ellipsoidal shape, or a rhomboidal shape.

10. A device according to claim 1 wherein the cage is provided with a pedestal for insertion into an outlet of the urinal through which effluent flows.

11. A device according to claim 8 wherein the pedestal is tapered so as to fit in different sizes of outlet opening.

12. A device according to claim 10 wherein the pedestal comprises a plurality of spaced fingers.

13. A device according to claim 8 wherein the pedestal is a perforated tube.

14. A device according to claim 8 wherein the cage is provided with a plurality of spaced fingers.
