Overfill prevention cap

Abstract

The disclosed technology includes a fill cap comprising a cap body including a well formed within said cap body, and a non-venting center hole positioned at the center of the cap body.

What is claimed is: 
     
         1 . A fill cap comprising:
 a cap body;   a well formed within the cap body; and   a non-venting center hole positioned at a center of the cap body.   
     
     
         2 . The fill cap of  claim 1 , wherein the cap body is configured to receive a shut-off valve. 
     
     
         3 . The fill cap of  claim 2 , wherein the non-venting center hole comprises interior threads for coupling the shut-off valve to the cap body. 
     
     
         4 . The fill cap of  claim 3 , wherein the shut-off valve is a float valve. 
     
     
         5 . The fill cap of  claim 1 , wherein the cap body is configured to receive a quick connect adapter. 
     
     
         6 . The fill cap of  claim 5 , wherein the cap body comprises an adapter protrusion extending from the bottom wall of the well and into an interior of the well, wherein an interior surface of the adapter protrusion is formed by the non-venting center hole, and wherein an exterior surface of the adapter protrusion comprises threads coupling the quick connect adapter to the cap body. 
     
     
         7 . The fill cap of  claim 1 , further comprising a weep hole provided through a bottom wall of the well. 
     
     
         8 . The fill cap of  claim 1 , wherein the cap body further comprises a vent hole positioned upward from the well. 
     
     
         9 . The fill cap of  claim 8 , wherein the cap body further comprises a ridged grip and the vent hole is positioned thereon. 
     
     
         10 . A portable floor scrubber comprising:
 a container having an aperture to receive water; and   a fill cap configured to removably couple to the aperture of the container, the fill cap comprising:
 a cap body comprising:
 a well formed within the cap body; and 
 a non-venting center hole positioned at a center of the cap body; 
 
 a quick connect adapter coupled to the cap body and configured to couple to a water source; and 
 a shut-off valve coupled to the cap body and configured to stop a flow of water from the water source into the container when a volume of water in the container reaches a predetermined level. 
   
     
     
         11 . The portable floor scrubber of  claim 10 , wherein the non-venting center hole comprises interior threads removably coupling the shut-off valve to the cap body. 
     
     
         12 . The portable floor scrubber of  claim 11 , wherein the cap body comprises a valve protrusion extending downward from the well, such that the shut-off valve is: positioned below the bottom wall of the well when coupled to the cap body, and interior to the container when the fill cap is removably coupled to the container. 
     
     
         13 . The portable floor scrubber of  claim 10 , wherein the cap body comprises an adapter protrusion extending from the bottom wall of the well and into an interior of the well, wherein an interior surface of the adapter protrusion is formed by the non-venting center hole, and wherein an exterior surface of the adapter protrusion comprises threads for coupling the quick connect adapter to the cap body. 
     
     
         14 . The portable floor scrubber of  claim 10 , wherein the cap body comprises a flange, and wherein a bottom surface of the flange abuts an exterior surface of the container when the fill cap is received by the aperture of the container. 
     
     
         15 . The portable floor scrubber of  claim 10 , wherein the cap body further comprises a vent hole positioned upward from the well. 
     
     
         16 . The portable floor scrubber of  claim 15 , wherein the cap body further comprises a ridged grip and the vent hole is positioned thereon. 
     
     
         17 . A fill cap for limiting a volume of fluid to be received by a fluid container, comprising:
 a cap body comprising;
 a well formed within the cap body; 
 a non-venting center hole positioned at a center of the cap body; a flange; and 
 a circular wall extending downward from the flange, the circular wall comprising threads provided on an exterior surface; 
   a shut-off valve coupled to the cap body; and   a quick connect adapter coupled to the cap body.   
     
     
         18 . The fill cap of  claim 17 , wherein the quick connect adapter is configured to couple to a hose adapter. 
     
     
         19 . The fill cap of  claim 17 , wherein the cap body further comprises a ridged grip extending upward from the flange and a vent hole positioned on the ridged grip. 
     
     
         20 . The fill cap of  claim 17 , wherein the cap body further comprises a weep hole provided through a bottom wall of the well.
