Abstract

A dissolved ozone delivery system comprises a generator for producing gaseous ozone, a bottle for holding a liquid suitable for receiving the gaseous ozone, flow conduits for delivering the gaseous ozone to the bottle and dissolving the ozone into the liquid to form an ozonated liquid, and a multicomponent bottle closure sealing device. The multicomponent bottle closure sealing has several discrete gas flow passageways for channeling the ozone gas into the bottle, venting undissolved gas and delivering the ozonated liquid to an exterior surface for decontamination thereof or medical instruments for sterilization or use in medical or dental procedures.

Claims

1. An improved system for delivering a liquid containing ozone dissolved therein, the ozone contained in the liquid being present in concentrations sufficient for decontaminating surfaces comprising;

a generator assembly for producing gaseous ozone, the generator assembly comprising a generator for converting oxygen to ozone and providing an ozone containing gas stream, and an oxygen source for delivering an oxygen containing gas stream to the generator,

a container for holding a liquid, the liquid suitable for receiving the ozone containing gas stream produced by the generator to form a liquid with ozone dissolved therein,

a conduit having a first end attached to a gas exit port on the generator for delivering ozone containing gas stream from the generator to an interior of the container and into the liquid in the container so as to form a liquid containing dissolved ozone, and

a container sealing device, comprising a closure assembly for attachment to an opening in the container to provide a pressure tight seal, the conduit passing through the closure assembly in a leak proof manner,

wherein the improvement comprises said closure assembly comprising an upper portion and a lower portion, the lower portion separable from the upper portion while the lower portion remains secured in the container opening, the upper portion attached to the generator such that, when the upper portion and the lower portion are joined the ozone containing gas stream produced in the generator passes through aligned flowpaths in the joined upper and lower portion in a leak proof manner, the conduit having a second end located below an upper surface of the liquid in the container, the second end having a gas diffuser attached thereto for distributing the ozone containing gas stream into the liquid to create the liquid containing dissolved ozone therein, the lower portion when separated from the upper portion remaining attached to the container and delivering the liquid containing dissolved ozone therein without removal of the lower portion.

2. The system of claim 1 wherein the closure assembly further includes

a. one or more openings, the one or more openings configured to allow removal from the container of undissolved ozone or delivery to the container of a pressurizing gas, and

b. a dissolved ozone and water delivery tube extending from a bottom portion of the closure assembly to a point adjacent the bottom of the container, the point adjacent the bottom of the container being within the liquid in the container.

3. The system of claim 1 wherein the oxygen source for delivering an oxygen containing gas stream to the generator comprises a gas pump, bottled air or oxygen, or an oxygen generator.

4. The system of claim 1 further including a liquid level sensor to indicate the presence of liquid in the container.

5. The system of claim 1 wherein the ozone dissolved in the liquid forms a liquid with a dissolved ozone concentration of ≧

2.0 ppm, said liquid deliverable to a surface to be decontaminated.

6. The system of claim 1 wherein the upper portion and lower portions of the closure assembly comprises a twist to lock connect/disconnect assembly to provide the flow path alignment.

7. The system of claim 6, wherein twist to lock connect/disconnect assembly provides an air tight seal on a top of the battle container.
