Abstract

A portable water purification kit and filter wherein the filter is comprised of a bed of particulate adsorbent material in a flow through casing provided with end caps, with one of the caps being a flexible cap, which is capable of being deformed for the application of a force to water flowing in the casing to increase the rate of flow through the particulate adsorbent. The filter is included in a portable kit for water purification comprised of a kit package which is a container for water having a removable cover, with the water filter and a tablet package, which includes a plurality of bacterial disinfectant tablets being included within the water container to provide a unified package.

Claims

1. A packaged kit for use in the purification of water, comprising:

a kit package comprising a container for retaining water and a removable cover closing said container;

a water filter in said kit package which is removable therefrom, said water filter comprising a flow through casing having an inlet end and an opposite outlet end to provide for axial flow through the casing, said casing including a bed of particulate adsorbent for adsorbing impurities from the water and first and second permeable supporting members within the casing supporting and confining said bed of particulate adsorbent therebetween over the casing crosssection, said casing including a water reservoir space between the inlet end and supported bed of particulate adsorbent; and

a disinfectant package in said kit package which is removable therefrom, said disinfectant package including a disinfectant for water borne bacteria and viruses.

2. The kit of claim 1 wherein said water filter includes first and second removable caps for closing the casing.

3. The kit of claim 2 wherein one of said caps is a flexible cap capable of being deformed to apply a force to water in the casing to increase the rate of water flow through the bed of particulate adsorbent.

4. The kit of claim 2 wherein first and second removable caps close the ends of the casing.

5. The kit of claim 4 wherein the disinfectant package is packaged within the water reservoir space of the casing.

6. The kit of claim 2 wherein the particulate adsorbent is activated carbon.

7. The kit of claim 6 wherein the disinfectant is tetraglycine hydroperiodide.

8. The kit of claim 7 wherein one of said caps is a flexible cap capable of being deformed to apply a force to water in the casing to increase the rate of water flow through the bed of particulate adsorbent.

9. The kit of claim 1 wherein the kit package is further comprised of another water container nested over said water container and a wrap covering said water container and said another water container.

10. The kit of claim 9 wherein the kit package further includes another removable cover for covering said another water container.

11. The kit of claim 9 wherein the particulate adsorbent is activated carbon.
