Treatment Device For Urinals

Abstract

The inventive subject matter provides apparatus, systems and methods in which a treatment device for a urinal (e.g., waterless urinal, waterless conversion, “P” trap in addition to skirt valve) is effective to reduce insects, uric acid buildup and odor in urinals and urinal pipes. The treatment device is typically installed in a urinal cartridge having a valve (e.g., a skirt valve), and comprises an upper dispenser positioned above the valve and a lower dispenser positioned below the valve.

What is claimed is: 
     
         1 . A treatment device for a urinal cartridge having a valve, the treatment device comprising:
 an upper dispenser positioned above the valve; and   a lower dispenser positioned below the valve.   
     
     
         2 . The treatment device of  claim 1 , wherein the valve has a first skirt, and further comprising a post about which is at least partially disposed both the first skirt and the upper dispenser. 
     
     
         3 . The treatment device of  claim 1 , wherein the valve has a first skirt, and further comprising a post about which is at least partially disposed both the first skirt and the lower dispenser. 
     
     
         4 . The treatment device of  claim 1 , wherein the valve has a first skirt, and further comprising a post about which is at least partially disposed (a) the first skirt, (b) the upper dispenser, and (c) the lower dispenser. 
     
     
         5 . The treatment device of  claim 1 , wherein the valve has a first skirt, and further comprising a post about which is at least partially disposed (a) the first skirt, (b) a second skirt, and (c) the lower dispenser. 
     
     
         6 . The treatment device of  claim 1 , further comprising a deodorant configured to be dispensed by the upper dispenser. 
     
     
         7 . The treatment device of  claim 6 , wherein the deodorant is configured as a solid pellet. 
     
     
         8 . The treatment device of  claim 1 , further comprising a locking mechanism that locks the upper dispenser to the cartridge. 
     
     
         9 . The treatment device of  claim 8 , wherein the locking mechanism comprises a detent. 
     
     
         10 . The treatment device of  claim 1 , further comprising an active agent configured to be dispensed by the lower dispenser, wherein the active agent is selected from the list consisting of an insecticide and a uric acid-consuming bacteria. 
     
     
         11 . The treatment device of  claim 1 , further comprising a fastening mechanism that fastens the lower dispenser to the cartridge. 
     
     
         12 . The treatment device of  claim 11 , further comprising a post about which the valve is disposed, and wherein the fastening mechanism comprises mating inner threads on the lower dispenser and outer threads on the post. 
     
     
         13 . The treatment device of  claim 11 , further comprising a post about which the valve is disposed, and wherein the fastening mechanism comprises a fastener with a hole that slidably couples with the post. 
     
     
         14 . The treatment device of  claim 13 , wherein the fastener comprises a rib that engages a hole disposed on the lower dispenser. 
     
     
         15 . The treatment device of  claim 1 , wherein the upper and lower dispensers have a diameter between 2 and 4 inches. 
     
     
         16 . The treatment device of  claim 1 , further comprising a perforated grate that is positioned above the upper dispenser to retain the upper dispenser in the urinal cartridge. 
     
     
         17 . The treatment device of  claim 1 , wherein the upper dispenser has a top side having a downward sloping surface that slopes towards a bottom side of the upper dispenser. 
     
     
         18 . The treatment device of  claim 1 , wherein the upper dispenser comprises a cavity. 
     
     
         19 . The treatment device of  claim 1 , wherein the upper dispenser has a height between 0.5 and 1.5 inches, and the lower dispenser has a height between 0.5 and 1 inch. 
     
     
         20 . The treatment device of  claim 1 , wherein a hole disposed on the upper dispenser has a smaller diameter than a cavity disposed on the lower dispenser.
