Abstract
Abstract A fluid-tight contact lens storage and carrying case of small size of polyethylene or plastic-like material, preferably clear or of translucent color, allows contact lenses to be conveniently stored when not being worn, and provides a pocket and/or hand-bag carrying and/or overnight storage case therefor, and further provides for a fluid reservoir allowing dispensing of wetting/cleaning fluid to the contact lens prior to insertion in the eye or storage in the case. The case as normally used comprises only one functional unit, but may be disassembled for initial filling or replenishing of the fluid reservoir.

Claim 1
Independent Claim
219 words
A contact lens case of one functional unit, there being no segments completely disattachable from the unit during normal use, constructed of a flexible, plastic-like material, comprising: a fluid reservoir of cylindrical design, a concave depression on the base of said reservoir creating a primary storage space for a contact lens, a snap-fit primary lens storage cap covering the primary lens storage space, a protruding lip appended to the primary lens storage cap to aid manipulation, a strap hinge connecting said primary cap with said reservoir, a concave depression on the outer surface in the base of said primary lens storage cap creating a secondary storage space for a contact lens, a snap-fit secondary storage cap covering the secondary lens storage space, a protruding lip appended to the secondary lens storage cap to aid manipulation, a strap hinge connecting said secondary cap with the strap of the primary cap, transverse ribs on the strap hinges for the storage caps, a fluid dispensing structure on the upper end of the fluid reservoir cylinder, a snap-fit cap enclosing the fluid dispensing structure, an interlocking fit between the fluid dispensing structure and the fluid reservoir whereby the fluid dispensing structure may be releasably secured to said fluid reservoir cylinder, providing a fluid-tight seal, and separable to provide access to the fluid reservoir.
