Abstract An ultraviolet sterilizer for a drinking glass, cup, and the like, comprising an ultraviolet bulb mounted in a housing, a reflector positioned around said bulb, a seating or positioning ring mounted on a base plate so as to receive the drinking glass and hold it in position beneath the bulb so that direct ultraviolet rays strike the inside of the glass and indirect ultraviolet rays from the reflector strike the outside of the glass to insure thorough sterilization of the glass, an electrical starter switch mounted on a wall plate beside the glass and connected in electrical circuit with the bulb, and a spring-backed actuating plate hingedly mounted on the wall plate with its bottom edge normally positioned over the seating ring so that the inserting of the drinking glass into said ring pushes the actuating plate to press against and close the starter switch to turn on the bulb. A timer may be provided to turn off the bulb after a pre-set time period.
An ultraviolet sterilizer for a drinking glass, cup, or the like comprising an ultraviolet ray source mounted in a housing, a reflector positioned around said ray source, a base plate connected to the housing by a wall plate, ring means including a seating ring mounted in the base plate for holding the drinking glass in position beneath the ray source so that the ultraviolet rays strike the inside and outside of the glass, an electrical switch mounted on the wall plate and connected in circuit with the ultraviolet ray source, an actuating plate hingedly mounted on the wall plate, and a spring mounted on the wall plate and pushing against said actuating plate to normally position the bottom edge of the actuating plate over the seating ring when the glass is not seated in the ring, so that, in setting the drinking glass into the ring, the drinking glass pushes the actuating plate against the force of said spring to actuate said switch to turn on the ultraviolet ray source to sterilize the glass, said ring means maintaining said switch closed by holding the drinking glass in position against said actuating plate and against the force of said spring to maintain the ultraviolet ray source in activated condition.
