Title:	Leakproof locking sterile water valve system
Abstract:	A locking sterile water valve system releasably couples a sterile water valve to a cage. The water valve is releasably coupled to an outside water supply while maintaining a barrier condition. A locking member is attached to the animal cage. A raised portion of the locking member is received in a recessed portion of the sterile water valve assembly. The water valve can be rotated for snapping the water valve into locking engagement with the locking member connecting the water valve assembly to the cage. An internal cup can be used with the water valve for collecting water leaking from the valve to prevent water from leaking into the cage and jeopardizing the animals and maintaining barrier condition.

Patent Claims:	1. A sterile water valve system for an animal cage, said cage including at least one wall, said system comprising: sterile water valve means for supplying water to said cage, said sterile water valve means removably connected to a water supply; and a locking member removably coupled to said sterile water valve means, said locking member being attached to said cage, wherein said sterile water valve means can be disconnected from said water supply and remain with said cage for maintaining a barrier condition in said cage and thereafter said sterile water valve means can be disconnected from said cage for stackability of said cage during cage washing and sterilization. 2. The water valve system of claim 1 wherein said water valve means comprises: a water valve; a housing surrounding a portion of said water valve. 3. The water valve system of claim 2 wherein said housing includes at least one recessed channel portion and said locking member includes at least one raised portion, said raised portion of said locking member being received in said recessed channel portion of said housing. 4. The water valve system of claim 3 wherein said recessed portion comprises a first recessed channel portion coupled to a second recessed channel portion, said second recessed channel having an L-shape, said raised portion being inserted in said first recessed channel portion and rotated into said second recessed channel portion for locking said water valve means to said cage. 5. The water valve system of claim 4 wherein said raised portion is rotated from said second recessed channel portion to said first recessed channel portion for unlocking said water valve means from said cage. 6. The water valve system of claim 5 wherein said water valve means is removably connected to said water supply with a positive quick disconnect assembly. 7. The water valve system of claim 6 wherein said locking member has an aperture therein and said cage wall has an opening therein, said aperture of said locking member being positioned over said opening, and said aperture receiving said water valve. 8. A sterile water valve system for an animal cage, said cage including at least one wall, said system comprising: a water valve for supplying water to said cage, said water valve being removably connected to a water supply with a positive quick disconnect assembly; a locking member attached to said cage removably coupled to said water valve, said locking member having an aperture therein and said cage wall has an opening therein, said aperture of said locking member being positioned over said opening, said aperture receiving said water valve; a housing surrounding a portion of said water valve, said housing includes a first recessed channel portion coupled to a second recessed channel portion, said second recessed channel portion having an L-shape, said locking member includes at least one raised portion, said raised portion being inserted in said first recessed channel portion and rotated into said second recessed channel portion for locking said water valve to said cage, said raised portion being rotated from said second recessed channel portion to said first recessed channel portion for unlocking said water valve means from said cage; and an internal cup, said cup having a front end and a rear end, said internal cup having a slot at said rear end, said front end of said cup being attached to said cage, said water valve being received within said internal cup and positioned adjacent said slot; and an outlet in the front end of said cup, wherein water which drips from said water valve exits said cup through said outlet. 9. The water valve system of claim 18 wherein said locking member has a backplate with said aperture therein, said backplate being coupled to said front end of said cup. 10. The water valve system of claim 9 in which said cup has a cavity positioned between said front and said rear end, said water valve means being received in said cavity and said cavity having an inner surface, wherein said water drips from said water valve to said inner surface of said cup to said outlet end to outside of said cage. 11. The water valve system of claim 10 wherein said raised portion of said locking member is an end of a spring wire. 12. The water valve system of claim 11 wherein said locking member includes a pair of said ends of said spring wire. 13. The water valve system of claim 12 wherein said locking member has a collar, a c-shaped spring wire between said ends of said spring wire protruding through an aperture in said collar, wherein said c-shaped spring wire is biased to said collar. 14. The water system of claim 13 wherein said housing includes a pair of said first and second recessed portions, each of said recessed channel portions having a depression and a hole, respective one of said spring wire ends being snapped into a respective one of said holes for locking said water means to said cage. 15. The water system of claim 14 wherein said water means further comprises: nut means for attaching said housing to said water, said nut means being positioned on the outside surface of said water. 16. The water system of claim 15 further comprising: a water line connector connected to said water manifold, said water line connector having a female quick disconnect end. 17. The water system of claim 16 wherein said water means has a male quick disconnect end, said male end of said water means being received in said female quick disconnect end of said water line connector.
