Abstract

An apparatus for storing and disinfecting a fluid includes a container (12) for containing the fluid and a cap member (16). The container (12) defines an opening (14) through which the fluid is dispensed therein and is removed therefrom. The cap member (16) removably seals the opening of the container (12). An ultraviolet source (24) is mounted to the cap member (16). The ultraviolet source (24) emits ultraviolet radiation to disinfect the fluid contained in the container (12).

Claims

1. An apparatus for storing and disinfecting a fluid, the apparatus comprising:

a container for containing the fluid, the container having an opening therein;

a cap member which removably seals the opening of the container;

an ultraviolet source for emitting radiation to disinfect the fluid; and

a wind-up source for powering the ultraviolet source, wherein the ultraviolet source is mounted to the cap member, and the cap member having at least two electrical contacts in electrical communication with the ultraviolet source, and the container also having two electrical contacts in electrical communication with the wind-up source, and the at least electrical contacts of the cap member respectively mate with the at least two electrical contacts of the container when the cap member is coupled to the container.

2. The apparatus of claim 1 further comprising a control circuit operative to control a disinfect cycle of the ultraviolet source.

3. The apparatus of claim 2 further comprising an output device in communication with the control circuit to provide an indication of a status of the disinfect cycle.

4. A The apparatus of claim 3 wherein the output device provides one of an indication of a time remaining in the disinfect cycle, an indication of a completed disinfect cycle, and an indication of an in-progress disinfect cycle.

5. The apparatus of claim 3 wherein the indication includes one of an audible indication and a visual indication.

6. The apparatus of claim 2 wherein the control circuit is operative to inhibit illumination of the ultraviolet source when the cap is removed from the container.

7. The apparatus of claim 2 wherein the control circuit is operative to illuminate the ultraviolet source for a predetermined time duration.

8. The apparatus of claim 2 further comprising a sensor coupled to the container to sense a measure of quality of the fluid.

9. The apparatus of claim 1 wherein the container is sized for carrying by an individual and wherein the ultraviolet source emits ultraviolet radiation to disinfect the fluid contained in the container.

10. The apparatus of claim 1 wherein the fluid is received by and dispensed from the container via the opening.

11. The apparatus of claim 1 wherein the container at least partially thermally insulates the fluid from an exterior environment.

12. The apparatus of claim 1 wherein the container has an inner surface which is ultraviolet-reflecting.

13. The apparatus of claim 1 wherein the container has a body and a base, and wherein the base is rotatable with respect to the body to wind the wind-up source.

14. The apparatus of claim 1 wherein the container has a capacity less than or equal to 2 liters.

15. The apparatus of claim 1 further comprising:

a plug disposed within a plug-receiving cavity defined by the container, the plug housing an ultraviolet-sensitive material which visibly changes when subjected to ultraviolet radiation.

16. An apparatus for containing and disinfecting a fluid, the apparatus comprising:

a container for containing the fluid, the container having an opening therein, the container defining a plug-receiving cavity;

a cap member which removably seals the opening of the container;

an ultraviolet source for emitting radiation to disinfect the fluid; and

a plug disposed within the plug-receiving cavity defined by the container, the plug housing an ultraviolet-sensitive material which visibly changes when subjected to ultraviolet radiation and a wind-up source for powering the ultraviolet source, is located at the base of the container and is wound by rotating the base of the container with respect to the body of the container, wherein the ultraviolet source is mounted to the cap member, and the cap member having at least two electrical contacts in electrical communication with the ultraviolet source, and the container also having two electrical contacts in electrical communication with the wind-up source, and the at least electrical contacts of the cap member respectively mate with the at least two electrical contacts of the container when the cap member is coupled to the container.

17. The apparatus of claim 16 wherein the ultraviolet-sensitive material is externally viewable by removing the plug from the plug-receiving cavity.

18. An apparatus for storing and disinfecting a fluid, the apparatus comprising:

a container sized for carrying by an individual, the container for holding fluid to be disinfected and at least partially thermally-insulating the fluid from an external environment, the container having an ultraviolet-reflecting inner surface, a body, and a base which is rotatable with respect to the body, the container having at least two electrical contacts;

a cap member detachedly coupled to the container, the cap member having at least two electrical contacts which respectively mate with the at least two electrical contacts of the container when the cap member is coupled to the container;

an ultraviolet source for emitting radiation to disinfect the fluid mounted to the cap member and in electrical communication with the at least two electrical contacts of the cap member;

a control circuit integrated with at least one of the cap member and the container, the control circuit operative to control the ultraviolet source to disinfect fluid in the container during a disinfect cycle;

an output device mounted to at least one of the cap member and the container, the output device in communication with the control circuit to provide an indication of a status of the disinfect cycle; and

a wind-up source for powering the ultraviolet source and the control circuit, the wind-up source in electrical communication with the at least two electrical contacts of the container, the wind-up source located at the base of the container, wherein the wind-up source is wound by rotating the base of the container with respect to the body of the container.

19. The apparatus of claim 18 wherein the control circuit is operative to illuminate the ultraviolet source for a predetermined time duration in the disinfect cycle, and wherein the output device provides an indication of a time remaining in the disinfect cycle.

20. The apparatus of claim 18 further comprising a sensor to sense a measure of quality of the fluid, the sensor mounted to the inner surface of the container, the sensor in communication with the control circuit to terminate the disinfect cycle when the measure of quality of the fluid attains a predetermined criterion.

21. The apparatus of claim 19 wherein the container has a capacity less than or equal to 2 liters.
