Abstract
Abstract A lens holder is disclosed that includes a base having first and second corresponding convex surfaces on opposite sides with a pivot axis on the base adjacent the surfaces. First and second cover members of identical construction cooperate with opposite sides of the base and are pivoted on the pivot axis. The identical cover members each include a concave surface corresponding in configuration to the convex surfaces on the base and a pair of arms on one end of each cover member that define pivot surfaces. The pivot surfaces receive the pivot axis and the arms are positioned so that the first and second cover members have lateral edges aligned with each other, when the arms of the cover members are operatively engaged with the pivot axis. The cover members each include latch means releasably retaining the cover member in a closed position on the base in which the convex and concave surfaces are in juxtaposed relation to each other. The base is removably secured to a cap and the cap is adapted to be removably coupled to a container with the cap, base and cover positioned to locate the base in the container when the cap is coupled to the container. In addition, the cap defines a maximum pivoted position for the cover members when it is secured to the container to prevent separation of the cover members from the base, while the cover members can readily be separated from the base when the base is removed from the cap.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
141 words
A lens holder comprising a base having first and second corresponding convex surfaces on opposite sides; means defining a pivot axis on said base adjacent said surfaces; first and second cover members of identical construction respectively cooperating with said opposite sides of said base, each of said cover members having a concave surface corresponding substantially to the configuration of said convex surfaces; a pair of arms at one end of each cover member defining pivot surfaces to receive said pivot axis in operative engagement therewith, said arms being positioned so that said first and second cover members have lateral edges aligned with each other when said members are operatively engaged with said pivot axis; and latch means releasably retaining said cover members in a closed position on said base with the convex and concave surfaces in juxtaposed relation to each other.
Claim 2
Dependent Claim
141 words
A lens holder comprising a base having first and second corresponding convex surfaces on opposite sides; means defining a pivot axis on said base adjacent said surfaces; first and second cover members of identical construction respectively cooperating with said opposite sides of said base, each of said cover members having a concave surface corresponding substantially to the configuration of said convex surfaces; a pair of arms at one end of each cover member defining pivot surfaces to receive said pivot axis in operative engagement therewith, said arms being positioned so that said first and second cover members have lateral edges aligned with each other when said members are operatively engaged with said pivot axis; and latch means releasably retaining said cover members in a closed position on said base with the convex and concave surfaces in juxtaposed relation to each other.
Claim 3
Dependent Claim
71 words
A lens holder as defined in claim 1, in which said base has an extension at one end, further including a container and a cap adapted to be removably coupled with said container, said cap having means for receiving said extension to secure said base to said cap, said means for receiving said extension being positioned to locate said base in said container when said cap is coupled to said container.
Claim 4
Dependent Claim
74 words
A lens holder as defined in claim 2, in which said cover members are pivotable to an extreme position to separate said cover members from said base and in which said cap defines a maximum pivoted position for said cover members, said maximum pivoted position being located between said extreme position and said closed position to prevEnt said cover members from being separated from said base when said base is secured to said cap.
Claim 5
Dependent Claim
24 words
A lens holder as defined in claim 2, in which said base and cap, when in assembled condition, are removably secured to each other.
Claim 6
Dependent Claim
112 words
A lens holder as defined in claim 2, in which each of said pair of arms at one end of each cover is displaced to one side so that the center line between the arms of the pair does not coincide with the center line of the cover and in which said cover members are pivotably to an extreme position to separate said cover members from said base, said cap defining a maximum pivoted position for said cover members, said maximum pivoted position being located between said extreme position and said closed position to prevent said cover members from being separated from said base when said base is secured to said cap.
Claim 7
Dependent Claim
48 words
A lens holder as defined in claim 1, in which each of said pair of arms at one end of each cover is displaced to one side so that the center line of the arms of each pair does not coincide with the center line of the cover.
Claim 8
Dependent Claim
20 words
A lens holder as defined in claim 1, in which said base has slits extending from the respective convex surfaces.
Claim 9
Dependent Claim
20 words
A lens holder as defined in claim 7, in which each cover member has slots extending from its concave surface.
Claim 10
Dependent Claim
64 words
A lens holder as defined in claim 1, in which said base has lateral edges aligned with the lateral edges of said cover members, further including an extension at one end of said base, said extension having lateral edges spaced inwardly from the lateral edges of said base, the lateral edges of said extensions having integral pins extending outwardly to define said pivot axis.
Claim 11
Dependent Claim
58 words
A lens holder as defined in claim 9, in which said pins are positioned to define gaps between said base the the periphery of said pins and in which one arm of each pair of arms is located in a respective gap, said arms substantially filling said gaps between the lateral edges of said base and said extension.
Claim 12
Dependent Claim
70 words
A lens holder as defined in claim 10, in which said latch means includes a latch arm on the opposite end of each cover member, said latch arms being laterally offset from the center line of said cover members between said lateral edges, said latch arms and the opposite end of said base having cooperating latch surfaces to releasably retain said cover members in a closed position on said base.
Claim 13
Dependent Claim
35 words
A lens holder as defined in claim 11, in which said base has slits extending from the respective convex surfaces and each cover member has slots extending from its concave surface to an opposed surface.
Claim 14
Dependent Claim
42 words
A lens holder as defined in claim 10, in which said pivot surfaces have cylindrical portions circumscribing an arc of less than 180* so that said cover members are pivotable to an extreme position to separate said cover members from said base.
Claim 15
Dependent Claim
138 words
A lens holder comprising a base having first and second corresponding convex surfaces on opposite sides, means defining a pivot axis on said base adjacent said surfaces, first and second cover members of identical construction respectively cooperating with said opposite sides of said base, each of said cover members having a concave surface corresponding substantially to the configuration of said convex surfaces, means at one end of each cover member defining pivot surfaces to receive said pivot axis in operative engagement therewith, said means being positioned so that said first and second cover members have lateral edges aligned with each other when said members are operatively engaged with said pivot axis; and latch means releasably retaining said cover members in a closed position on said base with the convex and concave surfaces in juxtaposed relation to each other.
