Abstract
Abstract A lens-carrying device is adapted to receive and contain a plurality of optical lenses in side-by-side non-contacting relation. The device is constructed of a first tray and a second tray, adapted to be releasably engaged, with either tray serving as the base or cover of the device. Each tray contains at least one row of longitudinally-spaced side-by-side annular cavities. When the trays are engaged with each other, the annular cavities of each tray are juxtaposed in mirror relation to each other to form a plurality of side-by-side lens-carrying annular chambers for receiving and supporting optical lenses therein. Each chamber has a central peripheral slot for receiving and holding a lens having a thickness up to a first predetermined value, lateral step members adjacent the central peripheral slot for supporting above the central slot a lens having a thickness greater than the first predetermined value and up to a maximum predetermined value, and divider ribs adjacent the lateral step members for interconnecting adjacent chambers but preventing lenses in adjacent chambers from contacting each other. A large number of optical lenses of varying lens powers can thus be transported in a single lens carrier while preventing any damage to the center area of any of the optical lenses.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
172 words
A lens-carrying device adapted to receive and retain a plurality of optical lenses having a predetermined range of thicknesses in a spaced-apart non-contacting relations, comprising a first tray having a plurality of longitudinally-spaced side-by-side cavities; a second tray having a plurality of longitudinally-spaced side-by-side cavities; said first and second trays being releasably engagable such that the plurality of first tray cavities and plurality of second tray cavities are juxtaposed in mirror relation opposite each other to define a plurality of side-by-side lens-carrying chambers for receiving and retaining a plurality of optical lenses in side-by-side non-contacting relation; each of said chambers having a central peripheral slot for supporting on edge an optical lens having a thickness up to a first predetermined value, lateral step means adjacent said central peripheral slot for supporting on edge above said central peripheral slot an optical lens having a thickness greater than said first predetermined value and up to a maximum predetermined value and divider means adjacent said lateral means for preventing contact between lenses in adjacent chambers.
Claim 2
Dependent Claim
172 words
A lens-carrying device adapted to receive and retain a plurality of optical lenses having a predetermined range of thicknesses in a spaced-apart non-contacting relations, comprising a first tray having a plurality of longitudinally-spaced side-by-side cavities; a second tray having a plurality of longitudinally-spaced side-by-side cavities; said first and second trays being releasably engagable such that the plurality of first tray cavities and plurality of second tray cavities are juxtaposed in mirror relation opposite each other to define a plurality of side-by-side lens-carrying chambers for receiving and retaining a plurality of optical lenses in side-by-side non-contacting relation; each of said chambers having a central peripheral slot for supporting on edge an optical lens having a thickness up to a first predetermined value, lateral step means adjacent said central peripheral slot for supporting on edge above said central peripheral slot an optical lens having a thickness greater than said first predetermined value and up to a maximum predetermined value and divider means adjacent said lateral means for preventing contact between lenses in adjacent chambers.
