Abstract
An asepticizing case for the storage and transport of soft contact lenses wherein each lens is confined on a curved surface in a fluid environment without the direct application of force thereto. A flexible skirt having a smaller radius of curvature than that of the lens receiving surface is affixed to the cap to insure the positioning of each lens.
Claims5
A soft contact lens asepticizing case comprising:
- (a) a base member having a surface containing two spaced central raised portions for receiving a contact lens thereon and an upstanding wall member surrounding each said central portion, said wall member having a height greater than the height of said central portion whereby the addition of fluid to said base member enables the central portion to be covered with fluid;
- (b) sealing cap means for engaging each wall member and establishing a fluid-tight contact therewith;
- (c) means contained on each sealing cap means for permitting the attachment of an internal guide thereto;
- and
- (d) flexible internal guide means for attachment to each of said cap means, said guide means extending downwardly from said cap means to each central raised portion of said base member for maintaining a soft contact lens thereon, said guide means being spaced from said lens and containing at least one fluid passage therein to permit fluid to contact said lens.
