A toothbrush sanitizer has a housing containing a centrally located elongated ultraviolet bulb surrounded by cavities for receiving standing toothbrushes. The cavities having one side open to receive ultraviolet light, have highly reflective surfaces to reflect light passing through said open side toward all sides of the toothbrushes, and have bottom contours which make the toothbrushes self-aligning. An electronic circuit lights the ultraviolet bulb with a short on, long off duty cycle. The initial on cycle is longer than the rest of the on cycles and occurs immediately after the cover is closed. A labyrinth seal permits passage of a cooling updraft of air while blocking an escape of ultraviolet light.

A toothbrush sanitizer comprising an irradiating source of ultraviolet light; a housing having a plurality of areas for supporting toothbrushes in positions which expose substantially all of the parts of said toothbrushes which enter the mouth, including their bristles and handles, to an irradiation of light from said source; said housing having internal contours which direct the light to completely surround said brush so that all sides of both said bristles and handles of said brush are irradiated by said light, said housing being closed by a cover to contain all ultraviolet light from said source, cover switch means for preventing said light from lighting except when said cover is in place to contain said light, said cover having a lip with a predetermined wall thickness, and a labyrinth seal at the lip of said cover, said seal comprising two upstanding concentric walls on said housing separated by a space which is wider than said predetermined wall thickness of said cover lip, means for holding said cover in an elevated position between said concentric walls, and openings in the bottom of said housing to provide an entrance for air in order to provide an updraft of cool air between said openings and said labyrinth seal.
