Abstract
An appliance for electrically heated disinfection of contact lenses or similar ojects is provided with a molded plastic housing having a recessed cavity for insertion of a conventional side-by-side horizontal lens storage case containing the lenses immersed in disinfecting liquid, typically saline solution. The cavity has horizontally aligned opposite end openings through the sides of the housing and the openings are located and dimensioned to allow unobstructed sliding passage of the lens case from the cavity so that the lens case will fall by gravitation from the cavity through one of the openings when the housing is rotated 90.degree. to vertically align the openings. The cavity openings thus ensure that the lens case cannot be heated in the appliance in a vertical orientation which could damage the lenses by heated exposure above the level of the disinfecting liquid. The housing further includes a floor wall below the cavity and a cover portion overlying the cavity for preventing vertical access to the lens case and filling the case with saline solution when installed in the cavity. The appliance further includes components for electrically heating the lens case when installed in the cavity. Current is supplied to the electrical circuitry by typical electrical prong terminals projecting from a rear wall of the housing so that the prong terminals can be directly plugged into a conventional household electrical outlet.
