Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
162 words
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.
Claim 2
Dependent Claim
162 words
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.
Claim 3
Dependent Claim
39 words
The asepticizing case of claim 1 wherein each central raised portion of said base member is a raised dome having a curved central surface for receiving a contact lens thereon, the raised dome having a first radius of curvature.
Claim 4
Dependent Claim
48 words
The asepticizing case of claim 2 wherein each flexible internal guide means has a skirt portion adapted for contact with the peripheral portion of a raised dome, said skirt portion being spaced from the central portion of the dome when the sealing cap means engages the retaining wall.
Claim 5
Dependent Claim
50 words
The asepticizing case of claim 3 wherein the skirt portion of said guide means is curved having a second radius of curvature, said first radius being greater than said second radius to permit retention of the lens on the central portion of said dome without contact by said guide means.
Claim 6
Dependent Claim
24 words
The asepticizing case of claim 4 wherein the height of said upstanding wall member is substantially greater than the height of said central portion.
