  • Patent number: 6039928
    Abstract: A writing implement sterilization apparatus having ultraviolet sterilization in an enclosed container to kill bacteria and other disease carrying organisms. The invention comprises a horizontal or vertical container into which a user places pens, pencils, or other writing implements to be sterilized. An ultraviolet source within the container irradiates the writing implement thereby killing any microorganisms that might reside on the writing implements. 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 writing implements thereby providing further sterilization together with the ultraviolet radiation. An interlocking switch turns the UV source off when the container is opened.
