  • Spectacle case
    Patent number: 4401209
    Abstract: The present invention is related to an improved spectacle case which is capable of securely retaining a spectacle within it. Utilization of this improved spectacle case assures that the spectacle will not move within the case, even if the case is jostled. The spectacle case is capable of retaining a spectacle within it in such a fashion that the exterior surfaces of the lenses never come in contact with the case. The unique design of the case also prevents the temples of the spectacle from coming in contact with the interior surface of the lenses. The unique configuration of the spectacle case gives it vastly improved strength over presently used spectacle cases.
