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. ## Claims ### Claim 1 A portable ozonation apparatus for storing and purifying liquids comprising: a container having an opening for receiving a liquid; and a self-contained ozone generating system detachably mounted to the container at the opening, said self-contained ozone generating system including: a main body portion including at least one side wall and a top wall that collectively define an interior cavity; an electricity generating device mounted in the interior cavity, said electricity generating device including an output terminal and an activating mechanism which selectively establishes a flow of electricity to the output terminal; and an ozone generating device, including a discharge portion, detachably mounted to the main body portion, said ozone generating device being electrically connected to the output terminal of the electricity generating device wherein, upon establishing a flow of electricity to the output terminal, said ozone generating device produces an amount of ozone gas which is delivered, through the discharge portion, into the liquid in the container. ### Claim 2 (depends on 1) The portable ozonation apparatus of claim 1, wherein the electricity generating device is constituted by a generator. ### Claim 3 (depends on 2) The portable ozonation apparatus of claim 2, wherein the activating mechanism is constituted by a hand crank. ### Claim 4 (depends on 1) The portable ozonation apparatus of claim 1, wherein the container is formed from plastic. ### Claim 5 (depends on 4) The portable ozonation apparatus of claim 4, wherein the container includes a bottom wall portion, a side wall portion and a neck portion, said neck portion including a plurality of threads. ### Claim 6 (depends on 5) The portable ozonation apparatus of claim 5, wherein the main body portion defines a treatment cap including a lower edge portion, said lower edge portion including a plurality of threads adapted to matingly engage with the plurality of threads on the container. ### Claim 7 The portable ozonation apparatus of claim, 6 wherein the ozone generating device includes a main body having a first, threaded portion adapted to be connected to the treatment cap in the interior cavity and the second, discharge portion leading into the container. ### Claim 8 (depends on 7) The portable ozonation apparatus of claim 7, wherein wherein the threaded portion of the ozone generating device is adapted to connect to the output terminal of the electricity generating device. ### Claim 9 (depends on 1) The portable ozonation apparatus of claim 1, wherein the ozone generating device extends into the container. ### Claim 10 A self-contained ozone generating system adapted to be detachably mounted to a container comprising: a main body portion adapted to be detachably mounted to a container, said main body portion including at least one side wall and a top wall that collectively define an interior cavity; an electricity generating device mounted in the interior cavity, said electricity generating device including an output terminal and an activating mechanism which selectively establishes a flow of electricity to the output terminal; and an ozone generating device, including a discharge portion, detachably mounted to the main body portion, said ozone generating device being electrically connected to the output terminal of the electricity generating device wherein, upon establishing a flow of electricity to the output terminal, said ozone generating device produces an amount of ozone gas which is adapted to be delivered, through the discharge portion, into a liquid. ### Claim 11 (depends on 10) The self-contained ozone generating system of claim 10, wherein the electricity generating device is constituted by a hand cranked generator, said activating mechanism being a hand crank. ### Claim 12 (depends on 10) The self-contained ozone generating system of claim 10, wherein the main body portion defines a treatment cap having a lower edge portion, said lower edge portion including a plurality of threads adapted to matingly engage with the container. ### Claim 13 (depends on 12) The self-contained ozone generating system of claim 12, wherein the ozone generating device includes a main body portion having a first, threaded portion adapted to be connected to the treatment cap and the second, discharge portion. ### Claim 14 (depends on 13) The self-contained ozone generating system of claim 13, wherein the threaded portion of the ozone generating device is adapted to connect to the output terminal of the electricity generating device.
