  • Portable ozonation apparatus for storing and purifying liquid
    Patent number: 8540943
    Abstract: A portable ozonation apparatus for storing and purifying liquids includes a container having an opening for receiving a liquid and a treatment cap. The treatment cap is preferably detachably mounted to the container at the opening. Preferably, the treatment cap includes a main body portion having provided therein an electricity generating device and an ozone generating device. With this arrangement, un-purified liquid, such as water, is introduced into the container. The container is then inverted to bring the un-purified liquid into contact with the ozone generating device. At this point, the electricity generating device is activated to deliver an electrical current to the ozone generating device. Once powered, the ozone generating device produces ozone which is introduced into the liquid container. The ozone gas transforms un-purified liquid into a purified liquid suitable for consumption.
