Urinal Screen

Abstract

Embodiments of the invention provide domed urinal screens. In preferred embodiments the screens include a hub, a plurality of spokes radiating downward from the hub, and a plurality of concentric rings supported by the spokes. Compositions deterring accumulation of fluids on urinal screens are also disclosed.

We claim: 
     
         1 . A urinal screen comprising:
 a central hub;   a plurality of spokes depending outward and downward away from said central hub; and   a plurality of concentric rings, wherein the rings are centered about the central hub, and wherein the rings are supported by the plurality of spokes, and wherein the the spokes and rings define a semi-rigid domed shape.   
     
     
         2 . The urinal screen of  claim 1 , wherein said central hub is circular, spherical, annular, square, rhomboidal, or hemispherical. 
     
     
         3 . The urinal screen of  claim 1 , wherein said urinal screen comprises ethylvinyl acetate (EVA). 
     
     
         4 . The urinal screen of  claim 3 , wherein said urinal screen further comprises at least one member of the group consisting of dimethicone and silicone. 
     
     
         5 . The urinal screen of  claim 4 , further comprising at least one fragrance. 
     
     
         6 . The urinal screen of  claim 3 , further comprising at least one fragrance. 
     
     
         7 . The urinal screen of  claim 1 , wherein said plurality of spokes and said plurality of concentric rings form a framework of a cone. 
     
     
         8 . The urinal screen of  claim 1 , wherein said plurality of spokes and said plurality of concentric rings form a framework of a spherical cap. 
     
     
         9 . The urinal screen of  claim 1 , wherein said spokes have equal lengths. 
     
     
         10 . The urinal screen of  claim 1 , wherein each of said spokes has a top surface, and wherein the top surface of at least one spoke is peaked. 
     
     
         11 . The urinal screen of  claim 1 , wherein each of said spokes has a top surface, and wherein said the top surface of at least one spoke is contoured. 
     
     
         12 . The urinal screen of  claim 1 , wherein each of said spokes has a bottom surface, and wherein the bottom surface of at least one spoke is contoured. 
     
     
         13 . The urinal screen of  claim 1 , wherein each of said rings has a top surface, and wherein the top surface of at least one ring is peaked. 
     
     
         14 . The urinal screen of  claim 1 , wherein each of said rings has a bottom surface, and wherein the bottom surface of at least one ring is contoured, serrated, or arrayed with a plurality of vertical protrusions. 
     
     
         15 . The urinal screen of  claim 1 , wherein each of said rings has a circular cross-section. 
     
     
         16 . The urinal screen of  claim 1 , wherein each of said spokes has a bottom surface, and wherein the bottom surface of at least one of said spokes includes a linear protrusion along the length of said spoke. 
     
     
         17 . The urinal screen of  claim 1 , wherein at least one of said spokes and said rings is serrated on at least one edge. 
     
     
         18 . A urinal screen comprising EVA and at least one member of the group consisting of dimethicone, alkylmethylsiloxane, and silicone. 
     
     
         19 . The urinal screen of  claim 18 , further comprising at least one fragrance. 
     
     
         20 . A urinal screen comprising at least one member of the group consisting of dimethicone, alkylmethylsiloxane, and silicone.
