Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 103 words
An adapter insert for holding an optical disc in a package, the adapter insert comprises: a) a base panel of a flexible material, b) raised corner bosses at the corners of the base panel, wherein the bosses have downward sloping outside corner wedges and have inner peripheral edges which conform to the periphery of the optical disc to be held and which have support lands for supporting a portion of the periphery of the optical disc, and c) a center hub extending upward from the center of the base panel for fitting within a central bore of the optical disc to be held.
Claim 2
Dependent Claim 103 words
An adapter insert for holding an optical disc in a package, the adapter insert comprises: a) a base panel of a flexible material, b) raised corner bosses at the corners of the base panel, wherein the bosses have downward sloping outside corner wedges and have inner peripheral edges which conform to the periphery of the optical disc to be held and which have support lands for supporting a portion of the periphery of the optical disc, and c) a center hub extending upward from the center of the base panel for fitting within a central bore of the optical disc to be held.
Claim 3
Dependent Claim 33 words
The adapter insert of claim 1 in which the hub has a peripheral surface which tapers from a larger size at an outer end to a smaller size adjacent to the base panel.
Claim 4
Dependent Claim 28 words
The adapter insert of claim 2 in which the hub forms an interference fit with the bore of the optical disc to be held by the adapter insert.
Claim 5
Dependent Claim 23 words
The adapter insert of claim 2 in which the hub has inwardly directed recesses formed around an outer peripheral edge of the hub.
Claim 6
Dependent Claim 24 words
The adapter insert of claim 1 in which the flexible material is a polymer and the base panel has a thickness of 0.015 inch.
Claim 7
Dependent Claim 28 words
The adapter insert of claim 1 wherein there are four corner bosses, and the corner bosses have outer edges with at least one recess in each outer edge.
Claim 8
Dependent Claim 28 words
The adapter insert of claim 1 in which the raised corner bosses and the hub are formed from the flexible material and are integral with the base panel.
Claim 9
Dependent Claim 238 words
A jewel case assembly forming a package for a set of two optical discs, the assembly comprising a jewel case having a bottom section and a lid section hingedly connected together and having an optical disc tray in the bottom section for supporting a first optical disc, the lid section comprising a lid panel having spaced side walls, and tabs on the side walls extending inwardly to overlie the lid panel, and the tabs being spaced from an inner surface of the lid panel and an adapter insert having a peripheral size to fit between the side walls of the lid section and being sufficiently flexible to permit edge portions of the adapter insert to be inserted under the tabs of the lid panel, the adapter insert comprising (i) a base panel of flexible material, (ii) raised corner bosses with inner peripheral edges conforming to the periphery of a second optical disc to be held, the raised corner bosses having downward sloping outside corner wedges and having outer edges with inwardly extending recesses to receive the tabs of the lid section of the jewel case and having inner peripheral edges which conform to the periphery of the second optical disc to be held and which have support lands for supporting a portion of the periphery of the optical disc away from the surface of the base panel, and (iii) a center hub for retaining the second optical disc.
Claim 10
Dependent Claim 238 words
A jewel case assembly forming a package for a set of two optical discs, the assembly comprising a jewel case having a bottom section and a lid section hingedly connected together and having an optical disc tray in the bottom section for supporting a first optical disc, the lid section comprising a lid panel having spaced side walls, and tabs on the side walls extending inwardly to overlie the lid panel, and the tabs being spaced from an inner surface of the lid panel and an adapter insert having a peripheral size to fit between the side walls of the lid section and being sufficiently flexible to permit edge portions of the adapter insert to be inserted under the tabs of the lid panel, the adapter insert comprising (i) a base panel of flexible material, (ii) raised corner bosses with inner peripheral edges conforming to the periphery of a second optical disc to be held, the raised corner bosses having downward sloping outside corner wedges and having outer edges with inwardly extending recesses to receive the tabs of the lid section of the jewel case and having inner peripheral edges which conform to the periphery of the second optical disc to be held and which have support lands for supporting a portion of the periphery of the optical disc away from the surface of the base panel, and (iii) a center hub for retaining the second optical disc.
Claim 11
Dependent Claim 161 words
A package assembly for holding optical discs comprising an adapter insert comprising a base panel of a flexible material, raised corner bosses at the corners of the base panel, wherein the bosses have inner peripheral edges which conform to the periphery of the optical disc to be held and which have support lands for supporting a portion of the periphery of the optical disc and downward sloping outside corner wedges, and a center hub extending upward from the center of the base panel for fitting within a central bore of the optical disc to be held, and an outer covering comprising a base panel and a cover panel hingedly connected by a connecting panel, wherein the base panel comprises an upper layer and a lower layer which are partially attached to each other, the upper layer having corners with slots near the corners which allow for insertion of the corner wedges of the adapter insert between the upper and lower layers.
Claim 12
Dependent Claim 161 words
A package assembly for holding optical discs comprising an adapter insert comprising a base panel of a flexible material, raised corner bosses at the corners of the base panel, wherein the bosses have inner peripheral edges which conform to the periphery of the optical disc to be held and which have support lands for supporting a portion of the periphery of the optical disc and downward sloping outside corner wedges, and a center hub extending upward from the center of the base panel for fitting within a central bore of the optical disc to be held, and an outer covering comprising a base panel and a cover panel hingedly connected by a connecting panel, wherein the base panel comprises an upper layer and a lower layer which are partially attached to each other, the upper layer having corners with slots near the corners which allow for insertion of the corner wedges of the adapter insert between the upper and lower layers.
