CONTACT LENS DISINFECTING UNIT Abstract of the Disclosure The present invention relates to a thermal disinfec- ting unit for the disinfecting of a pair of contact lenses dis- posed within a lens case along with a quantity of disinfecting solution, wherein disinfecting is achieved upon the heating of the solution to a prescribed temperature. The unit as disclosed includes an outer casing made up of upper and lower assembled sections, with an internal heating arrangement disposed therein including a substantially planar lens case support surface. Aper- ture means are provided in the upper casing section and disposed in relation to the support surface to define a heater well for reception of the lens case. In one embodiment, the aperture means is defined by inwardly extending flange, with a gasket carried thereon, such that as the respective casing sections are drawn together, the gasket will firmly engage the planar support surface to seal the heater well from the interior of the unit. In a second embodiment, a lateral aperture is pro- vided whereby engagement of the lens case with the support surface is attained by a sliding action which serves to wipe the support surface clear of any granular or crystalline sub- stance which may have formed thereon. In addition, the dis- closure contemplates an internal heating mechanism designed and constructed, so that the support surface will be heated to a desired temperature and will remain at said temperature for a period of time, before there is any likelihood of operation of a thermostatic device, also carried by said heater block. -1a-
