ABSTRACT:
A contact lens case is provided which includes a cannister open at its upper end for receiving lens washing fluid and a cap adapted to be secured to and seal the cannister. The cap includes a securing ring adapted to engage the cannister so as to secure the cap to the cannister. The cap further includes a lens retaining portion having at least two lens receptacles pivotably mounted on a shoulder. A leaf spring is provided in the shoulder for urging the lens receptacles apart. A turning knob is provided on the cap and is connected to a planetary gear mechanism for causing the lens retaining portion to rotate in the cannister as the turning knob is rotated. Downwardly extending finger means are provided on each lens receptacle which are adapted to engage an elliptically shaped track at the base of the inner surface of the cannister to cause the receptacles to be simultaneously oscillated toward and away from the axis of rotation of the retaining portion as the receptacle portion is rotated about the circumference of the cannister.
