Claims
- 1. Apparatus for purifying a liquid comprising:
- a hollow unitary container defined by a bottom and an integral sidewall and having an open top for introducing a liquid into the container and a spout at the top open end of said container;
- a predetermined quantity of carbon being positioned in said container and being loosely arranged in the bottom portion of the container prior to heating the container and being arranged to freely move into the upper region of the container and mix with the liquid placed in said container;
- a filter positioned in said spout to remove particulate matter from the liquid as the liquid containing such particulate matter passes through the spout and to prevent the carbon from passing through said filter;
- said container being formed of a material capable of withstanding heat sufficient to raise the temperature of the liquid contents to about the boiling level whereby the contents are caused to interact with the carbon during heating and drive the carbon particles into the upper portion of the container to intimately interact with the heated water;
- said container being provided with a lid removably covering said open top; and
- said lid being perforated, said perforations being sufficient to permit venting of volatile matter from the container during heating.
- 2. The apparatus of claim 1 wherein said container is further provided with a handle to facilitate lifting of said container, said handle being formed of a material for insulating the holder's hand from the elevated temperature of the contents of said container.
- 3. The apparatus of claim 1 wherein at least a portion of said lid having said perforations is recessed to permit liquid to be collected thereon as the container is being filled to facilitate filling of the container without removal of the lid.
- 4. The apparatus of claim 1 wherein the bottom of the container is provided with a compartment defining an enclosed region;
- an electrical resistance type heater being provided in said enclosed region for heating the contents of said container.
- 5. The apparatus of claim 1 further comprising first and second sealing means provided over said lid and the opening of said spout for releasably sealing the contents of the container.
- 6. The apparatus of claim 5 wherein said sealing means is comprised of a thin sheet of material having an adhesive-like material for releasably affixing the sealing means to the container.
- 7. The apparatus of claim 1 wherein the bottom of the container is provided with an opening;
- manually operable valve means positioned to seal said bottom opening and movable between an open and closed position for selectively dispensing the contents of the container through said bottom opening.
- 8. The apparatus of claim 7 further comprising a second filter which substantially covers the opening in the bottom of the container.
