Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
256 words
A storage case for a compact optical disc comprising a body having top and bottom portions joined by sidewalls that define an opening in the body for receiving a tray, the tray having a narrow profile and a recess in a flat planar top surface for receiving a compact disc in a nested engagement, a leaf spring interposed between an edge of the tray and an inner surface of the body such that the spring is fully loaded with tension when the tray is received by the opening of the body and guided into a retracted position in which the tray is within the body, a latch mechanism integrally formed on each of two opposing sides of the tray, a flexuous and elastic finger of the latch whose bending movement is in a plane parallel with the flat planar top surface of the tray, an aperture in the sidewalls of the body for mating with the finger when the tray is fully retracted into the body, a bearing surface of the elastic finger extending through the aperture when the tray is in its fully retracted position and biasing against an opposing surface of the mated aperture to retain the tray in its retracted position with tension loaded in the leaf spring, and an indentation in the tray to provide a margin for the finger to flex inwardly in response to an external force, thus releasing the finger from the aperture and allowing the leaf spring to release its tension by ejecting the tray from the body.

Claim 3
Dependent Claim
22 words
The storage case for a compact optical disc as set forth in claim 1 wherein the spring is anchored to the tray.
Claim 4
Dependent Claim
24 words
The storage case for a compact optical disc as set forth in claim 1 wherein the spring is an integral extension of the tray.
Claim 5
Dependent Claim
26 words
The storage case for a compact optical disc as set forth in claim 1 wherein the spring is attached to the inner surface of the body.
Claim 6
Dependent Claim

The storage case for a compact optical disc as set forth in claim 1 wherein a transparent cover for retaining and displaying documents fits over the case.
Claim 7
Dependent Claim
53 words
The storage case for a compact optical disc as set forth in claim 5 wherein the transparent cover for displaying and retaining the documents comprises an apron with several inwardly extending pins for mating with recesses in the sidewalls of the case in a snap-fit engagement, which secures the cover onto the case.
Claim 8
Dependent Claim
46 words
The storage case for a compact optical disc as set forth in claim 6 wherein the cover is further comprised of a plurality of tabs each forming a slot for receiving an edge of a document such that the tabs collectively retain and frame the document.
Claim 9
Dependent Claim
20 words
The storage case for a compact optical disc as set forth in claim 1 wherein the case includes several trays.
Claim 10
Dependent Claim
40 words
The storage case for a compact optical disc as set forth in claim 8 wherein the case contains opposing support tracks for guiding the trays between extended and retracted positions, the support tracks vertically spacing each tray from other trays.
Claim 11
Dependent Claim
28 words
The storage case for a compact optical disc as set forth in claim 1 wherein the case is comprised of top and bottom portions mated at a seam.
Claim 12
Dependent Claim
23 words
The storage case for a compact optical disc as set forth in claim 10 wherein the top and bottom portions are identically formed.
Claim 13
Dependent Claim
75 words
The storage case for a compact optical disc as set forth in claim 1 wherein the spring is comprised of an elongated member with two hairpin bends at its ends, two arms extending from the elongated member at the hairpin bends, the elongated member spans an open back wall of the case and is retained in the case at the hairpin bends by slots formed by two opposing walls at the back of the case.
Claim 14
Dependent Claim
26 words
The storage case for a compact optical disc as set forth in claim 1 wherein the opening of the case is closed by a protective cover.
Claim 15
Dependent Claim
44 words
The storage case for a compact optical disc as set forth in claim 13 wherein the protective cover has side arms pivotally connecting the protective cover to the sidewalls of the case, the protective cover pivoting downwardly to expose the opening of the case.
Claim 16
Dependent Claim
44 words
