  • Patent number: 5117849
    Abstract: An apparatus having a casing and a rotating cover with baskets to hold the contact lenses which are to be cleaned. The rotating cover is set on the casing with a guide rod. The contact lenses are first lowered into a tub in the casing containing a cleaning and disinfecting solution. After an adjustable amount of time, the rotating cover is pushed up by a push rod. The tip of the push rod is guided down a helical groove, thus rotating the cover 180.degree.. At the end of its path, the push rod ends in a hole of the casing and the contact lenses are thus lowered into the tube containing the neutralization solution.
