<p>The disclosure relates to a lens case for supporting a pair of contact lenses in a liquid solution to be heated to an elevated temperature for effecting sterilization or disinfecting of the lenses. The lens case includes a generally cylindrical open ended container for housing the liquid, a cap for closing the open end of the container, and a lens holder arrangement for supporting the lenses to be sterilized. The cap includes means for supporting the lens holder and the lenses confined therein emersed within the liquid. Further, said cap includes a circumferential downturned annular flange that forms a recess within the cap to provide an air pocket and an area which provides an expansion chamber for the liquid. More specifically, upon assembly of the cap to a filled container, the air pocket will displace excess liquid from the container as the cap is assembled in place. Thus, the liquid level in the container is controlled with the area or air pocket therefore providing an expansion chamber for liquid vapors produced during heating. Further, the lens holder is of unique design in that it includes a central body having a pair of laterally and oppositely facing convex surfaces, and a like pair of covers having a concave inner surface corresponding to the convex surfaces of the central body. The covers are releasably and oppositely hinged with respect to the central body by resilient hinge members which releasably attach to the side edges of the central body for providing lateral opening and closing movement of the covers with respect to the central body. Said covers cooperate with the convex surface for confining a pair of contact lenses therebetween.</p> |
