Abstract

A water container assembly for drinking water includes a purifying unit located at the top of a container and mounted within the container. The purifying unit includes at least one filter having an outlet which communicates with the interior of the container. Water may be placed in the top of the purifying unit and then be purified as it passes through the filter and is discharged into the container.

Claims

1. A water container assembly for use on a water stand comprising a container for mounting on the water stand, a water purification unit in said container, said water purification unit comprising a housing mounted at the top of said container, said water purification unit having mounting means at its upper end, said mounting means being mounted st said top of said container with essentially all of said water purification unit being disposed within said container, the interior of said housing defining a chamber, an inlet at the upper portion of said chamber to permit tap water to be inserted into said chamber, a filter unit in said chamber, and said filter unit communicating with the interior of said container whereby the tap water flows by gravity through said filter unit where it is purified and then flows into said container.

2. The assembly of claim 1 wherein said housing is frusto-conically shaped with the larger portion of said frusto-conical shape being located at the top of said container whereby water may flow between the outer surface of said housing and the inner surface of said container.

3. The assembly of claim 2 wherein the upper edge of said housing is outwardly flared, said container being completely open at its upper edge, and said flared edge of said housing being mounted over said upper edge of said container.

4. The assembly of claim 3 wherein said housing is completely open at its upper end, and a cover detachably closing said open end of said housing.

5. The assembly of claim 4 including a handle on said cover.

6. The assembly of claim 5 wherein said cover terminates in a flared edge which conforms to the flaring of the upper edge of said housing and the upper edge of said container.

7. The assembly of claim 4 including at least

8. The assembly of claim 1 wherein said housing is of generally equal capacity to the capacity of the remaining portion of said container.

9. The assembly of claim 8 wherein said housing is made of stainless steel.

10. A water container assembly for use on a water stand comprising a container for mounting on the water stand, a water purification unit in said container, said water purification unit comprising a housing mounted at the top of said container, the interior of said housing defining a chamber, an inlet at the upper portion of said chamber to permit tap water to be inserted into said chamber, a filter unit in said chamber, said filter unit communicating with the interior of said container whereby the tap water flows by gravity through said filter unit where it is purified and then flows into said container said housing being frusto-conically shaped with the larger portion of said frusto-conical shape being located at the top of said container whereby water may flow between the outer surface of said housing and the inner surface of said container, the upper edge of said housing being outwardly flared, said container being completely open at its upper edge, said flared edge of said housing being mounted over said upper edge of said container, said housing being is completely open at its upper end, and a cover detachably closing said open end of said housing, a handle on said cover, said cover terminating in a flared edge which conforms to the flaring of the upper edge of said housing and the upper edge of said container at least two filters mounted to said housing, and each of said filters including an inner core of activated carbon surrounded by a shell of ceramic impregnated with silver.

11. The assembly of claim 10 wherein each of said filters is mounted to said base of said housing by a mount secured to coupling members to said base of said housing, a hole extending through said coupling members and said base, and said hole communicating with a tube exposed to said interior of said container whereby purified water may be discharged into said container from said tube.

12. A water purification unit comprising a frusto-conical housing having a side wall and a bottom wall and an open upper end, at least one filter mounted to said bottom wall of said housing in communication with an opening in said bottom wall of said housing, a discharge tube at said bottom wall of said housing in communication with said opening whereby tap water may be inserted into said housing and purified by passing through said filter to then be dispensed into a container which communicates with said tube, the upper edge of said frusto-conical housing being outwardly and downwardly flared to form a mounting lip for resting on the upper end of a container into which said unit may be disposed, and a cover disposed over the open end of said housing.

13. The unit of claim 12 wherein at least two filters are mounted in said housing.

14. The unit of claim 13 including a handle on said cover.

15. A water purification unit comprising a frusto-conical housing having a side wall and a bottom wall and an open upper end, at least two filters mounted to said bottom wall of said housing in communication with an opening in said bottom wall of said housing, a discharge tube at said bottom wall of said housing in communication with said opening whereby tap water may be inserted into said housing and purified by passing through said filter to then be disposed into a container which communicates with said tube, and each of said filters including an inner core of activated carbon surrounded by a shell of ceramic impregnated with silver.
