  • Patent number: 6435339
    Abstract: The present invention relates to a compact case for storing contact lenses that is designed to be attachable to a key ring and can be stored within the contact wearers pocket without being obtrusive. The contact lens case includes two reservoirs that share a common circular bottom wall. The reservoirs are coaxially oriented and are threaded to accept cylindrical closure caps that seal the reservoirs. The cylindrical closure caps engage the opposite ends of the cylindrical body and have inner peripheral surfaces that are coaxially related to the outer peripheral surfaces of the two cylindrical reservoirs of the body. The contact lens case further comprises a tab that extends tangentially outward from the central axis of the reservoirs. The tab includes an aperture that is adapted to accept a removable clip that allows for attachment of the contact lens case to a key ring.
