Abstract
Abstract A device for holding a pair of contact lenses comprises means, including a pair of substantially identically shaped elements, forming a pair of axially aligned lenses holding compartments, each of the elements including a base provided with openings to permit fluid flow through both of the lenses holding compartments, a displaceable cover for each compartment to releasably confine the lenses in the compartments, each cover having perforations to permit fluid to flow into and from the lenses holding compartments, and coupling means for axially aligning the identically shaped elements with the bases of the elements in abutting relationship to permit fluid to flow into and through both of the lenses holding compartments. The device conveniently and safely holds the lenses during cleaning under running tapwater or during immersion in a lens treating solution.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
119 words
A device for holding a pair of contact lenses, which comprises: means forming a pair of axially aligned lens holding compartments, said means comprising a pair of substantially identically shaped elements, each of said elements including a base having openings therein to permit fluid to flow through both of said lens holding compartments; a displaceable cover for each compartment to releasably confine the lenses in said lens holding compartments, each cover having perforations therein to permit fluid to flow into and from said lens holding compartments; and coupling means for axially aligning said identically shaped elements with the bases of said elements in abutting relationship to permit fluid to flow into and through both of said lens holding compartments.
Claim 2
Independent Claim
119 words
A device for holding a pair of contact lenses, which comprises: means forming a pair of axially aligned lens holding compartments, said means comprising a pair of substantially identically shaped elements, each of said elements including a base having openings therein to permit fluid to flow through both of said lens holding compartments; a displaceable cover for each compartment to releasably confine the lenses in said lens holding compartments, each cover having perforations therein to permit fluid to flow into and from said lens holding compartments; and coupling means for axially aligning said identically shaped elements with the bases of said elements in abutting relationship to permit fluid to flow into and through both of said lens holding compartments.
Claim 3
Dependent Claim
17 words
The device of claim 1, wherein: said coupling means is formed on said bases of said elements.
Claim 4
Dependent Claim
19 words
The device of claim 1, which includes: means for securing each of the displaceable covers in a closed position.
Claim 5
Dependent Claim
24 words
The device of claim 1, wherein the displaceable covers are provided with indicia for identifying lenses which are inserted in the lens holding compartments.
Claim 6
Independent Claim
130 words
A device for holding a pair of contact lenses, which comprises: means forming a pair of axially aligned lens holding compartments, said means comprising a pair of substantially identically shaped elements, each of said elements including a base having openings therein and a sidewall forming a single lens holding compartment with said base, said openings permitting fluid to flow through both of said lens holding compartments; and a displaceable cover for each compartment to releasably confine the lenses in said lens holding compartments, each cover having perforations therein to permit fluid to flow into and from said lens holding compartments; said pair of substantially identically shaped elements including means for securing the elements together so that the bases of each element abut with their openings aligned and form a platform.
Claim 7
Independent Claim
130 words
A device for holding a pair of contact lenses, which comprises: means forming a pair of axially aligned lens holding compartments, said means comprising a pair of substantially identically shaped elements, each of said elements including a base having openings therein and a sidewall forming a single lens holding compartment with said base, said openings permitting fluid to flow through both of said lens holding compartments; and a displaceable cover for each compartment to releasably confine the lenses in said lens holding compartments, each cover having perforations therein to permit fluid to flow into and from said lens holding compartments; said pair of substantially identically shaped elements including means for securing the elements together so that the bases of each element abut with their openings aligned and form a platform.
Claim 8
Independent Claim
101 words
A device for holding a pair of contact lenses, which comprises: an outer wall forming a hollow chamber; a platform mounted across said hollow chamber midway of its length to form a pair of axially aligned lens holding compartments within said hollow chamber; said platform being shaped on opposite surfaces to conform to the contour of one surface of the lens and having openings interconnecting said pair of lens holding compartments; and a perforated lid for each lens holding compartment to releasably confine a leNs in the compartment and to permit fluid to flow into and through the lens holding compartments.
Claim 9
Independent Claim
101 words
A device for holding a pair of contact lenses, which comprises: an outer wall forming a hollow chamber; a platform mounted across said hollow chamber midway of its length to form a pair of axially aligned lens holding compartments within said hollow chamber; said platform being shaped on opposite surfaces to conform to the contour of one surface of the lens and having openings interconnecting said pair of lens holding compartments; and a perforated lid for each lens holding compartment to releasably confine a leNs in the compartment and to permit fluid to flow into and through the lens holding compartments.
Claim 10
Independent Claim
110 words
A device for holding a pair of contact lenses, comprising: two substantially identically shaped elements, each of said elements including a base having openings therein, a sidewall forming a single lens holding compartment with said base, and a perforated lid to releasably confine a lens in each lens holding compartment, means for securing the elements together so that the bases of each element abut with their openings aligned, said sidewalls of the elements providing an outer wall forming a hollow chamber and said bases forming a platform mounted across said hollow chamber midway of its length to form a pair of axially aligned lens holding compartments within said hollow chamber.
Claim 11
Independent Claim
110 words
A device for holding a pair of contact lenses, comprising: two substantially identically shaped elements, each of said elements including a base having openings therein, a sidewall forming a single lens holding compartment with said base, and a perforated lid to releasably confine a lens in each lens holding compartment, means for securing the elements together so that the bases of each element abut with their openings aligned, said sidewalls of the elements providing an outer wall forming a hollow chamber and said bases forming a platform mounted across said hollow chamber midway of its length to form a pair of axially aligned lens holding compartments within said hollow chamber.
Claim 12
Independent Claim
108 words
A device for holding a pair of contact lenses which comprises: an outer cylindrical wall forming a cylindrical hollow chamber; a platform having concave upper and lower surfaces and mounted across said hollow chamber perpendicular to its axis and midway of its length to form a pair of dish-shaped lens holding compartments within said chamber; said platform having a plurality of arcuate-shaped openings extending radially outward from the axis of said chamber and interconnecting the lens holding compartments; and a perforated lid for each lens holding compartment to releasably confine a lens in the compartment and to permit fluid to flow into and through the lens holding compartments.
