Abstract: A lens treating device for treating a contact lens includes: an outer casing having a cylindrical body which is open at at least one of opposite axial ends, and at least one lid removably attached to the cylindrical body to close the axial end(s) thereof; and a lens storage container which is accommodated in the outer casing such that the container is axially slidingly reciprocable within the outer casing. The lens storage container has at least one cap member removably attached thereto. The lens storage container fluid-tightly receives therein the contact lens and a liquid for treating the contact lens, whereby the liquid is forced to flow within the container so as to clean the contact lens, by a reciprocating movement of the lens storage container when the outer casing is axially shaked or repeatedly inverted. A method of treating a contact lens by using such a lens treating device is also disclosed.

Abstract: A contact lens case including a cylindrical container body, a cap member for closing an opening of the container body, a support member which is attached at one end thereof to the cap member to extend therefrom in an axial direction of the container body, and a lens holder rotatably supported by the support member. The lens holder has one or more lens storage chamber each receiving the contact lens, and a plurality of holes which permit a liquid to flow therethrough. The present contact lens case further includes a detent structure for holding the lens holder selectively in a horizontal position in which the contact lens received in the holder has a horizontal attitude perpendicular to the axial direction of the container body, or in a vertical position in which the contact lens received has a vertical attitude parallel to the axial direction of the container body.

Abstract: A liquid purifying device for dispensing a liquid, including a container which has an interior space for storing a liquid, and a lid member for closing the interior space. The liquid is delivered out of the container, due to a pressure of a compressed air which is introduced into the interior space by air pumping means. The air pumping means includes a cylinder member which is reciprocated between an advanced position and a retracted position. The cylinder member is normally biased toward the advanced position, but may be held in the retracted position where appropriate. The lid member of the container has a liquid delivery path through which the liquid is delivered as desired, when a valve disposed in the path is placed in its open position upon pressing of a push-operated member. In the liquid delivery path, there is provided a filter adapted to remove bacteria from the liquid delivered through the path.
