ABSTRACT:
A multi-function canister, mountable within a urinal chamber, is held in place by a spring clip that is insertable in one of the flush apertures at the top of the chamber, and which biases the canister against the chamber rear wall. The canister includes an onboard fragrance tablet that continually dispenses an odor-counteracting aroma. The canister also includes a reservoir filled with a solid compound, a dissolved portion of which is released into the chamber with each flush by water flowing from the aperture in which the spring clip is installed. A deflector tray limits the amount of water flowing into the reservoir. The dissolved portion inhibits the formation of potassium phosphate scale (urine calculus) on the surfaces of the urinal chamber and drainage pipes. The solid compound may be sulfamic acid. The canister may also include a grill which covers and protects the fragrance tablet.
