Title:
TOILET SEAT STERILIZATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO2001070277
Kind Code:
A3
Abstract:
A toilet seat sterilization apparatus having ultraviolet sterilization in an enclosed container to kill bacteria and other disease carrying organisms. The invention comprises an ultraviolet source within the toilet seat lid that irradiates the toilet seat thereby killing any microorganisms that might reside on the toilet seat. Ultraviolet radiation below 200 nm can also be used thereby creating ozone gas having germicidal characteristics. The ozone gas is circulating in and around the toilet seat and bowl thereby providing further sterilization together with the ultraviolet radiation. An interlocking switch turns the UV source off when the container is opened.
