Contact lens holder and treating device

A lens treating device for treating a contact lens, comprising:

• an elongate cylindrical outer case having a cylindrical body which is open at at least one of opposite axial ends, and at least one lid removably attached to said cylindrical body to close said at least one axial end thereof;
• and
• a contact lens case, for accommodating a contact lens, as an inner case, for fluid-tightly receiving the contact lens and a liquid for treating the contact lens, said inner case being accommodated in said outer case such that said inner case is axially slidingly reciprocable within said outer case, whereby said liquid is forced to flow within said inner case so as to clean the contact lens, by a reciprocating movement of said inner case when said outer case is axially shaked or repeatedly inverted, said contact lens case comprising:
• a cylindrical container body closed at one axial end, for receiving a liquid for treating the contact lens;
• a cap member removably attached to the other axial end of said container body to fluid-tightly close an opening of the body, so that an enclosed space is defined between said cap member and said container body;
• a support member which is attached at one end thereof to the inside of said cap member, and which extends from said cap member into said enclosed space in an axial direction of said container body;
• a lens holder rotatably supported at the other end of said support member and accommodated in said enclosed space, said lens holder comprising a plate member and at least one cover forming at least one lens storage chamber each for receiving the contact lens, said lens holder having a plurality of through-holes which permit said liquid to flow therethrough;
• and
• detent means disposed between said lens holder and said support member for preventing said lens holder from freely rotating in said enclosed space, and for holding said lens holder selectively in a horizontal position in which said lens holder has a horizontal posture substantially perpendicular to said axial direction of said container body, or a vertical position in which said lens holder has a vertical posture substantially parallel to said axial direction of the container body, so that the contact lens received in said at least one lens storage chamber has a horizontal attitude substantially perpendicular to said axial direction of the container body when said lens holder is held in said horizontal position, and a vertical attitude substantially parallel to said axial direction of the container body when said lens holder is held in said vertical position, said detent means holding said lens holder in said vertical position so that the contact lens received in said lens holder has said vertical attitude when the lens is put into or taken out of said lens holder, and holding said lens holder in said horizontal position so that the contact lens has said horizontal attitude during cleaning of the contact lens.
