Abstract
Abstract A protector/holder for a computer, video or phonograph disk. The protector/holder is in the form of a housing having spaced top and bottom wall surfaces, two opposed side walls and an enclosed bottom edge forming a three sided closed enclosure with an open top end. The spaced edges of the top and bottom wall surfaces at the open top end are formed with inwardly tapering surfaces. The bottom wall surface extends a short distance beyond the length of the outer edge of the top wall surface. A pair of aligned slots are formed centrally within the top and bottom wall surfaces adjacent the open edges to provide access to the disk contained within the housing. An outwardly tapering notch is formed interiorally within the housing at the bottom end of the housing to securely receive the bottom edge therein.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
157 words
A disk protector/holder comprising: a housing formed of rigid material having spaced top and bottom major wall surfaces, opposed side walls, a closed bottom edge and an open top end; a first outer edge of the bottom wall surface adjacent the open top end extending outward a short distance beyond a second outer edge of the spaced top wall surface adjacent the open top end, the first and second outer edges of the top and bottom wall surfaces adjacent the open top end having inwardly tapering surfaces; a pair of aligned slots formed in the top and bottom wall surfaces adjacent to the first and second outer edges of the top and bottom wall surfaces and extending downward toward the bottom edge and upwardly extending surfaces formed adjacent the bottom edge defining a sharply-angled V-shaped notch between the bottom edge and the top and bottom wall surfaces to securely receive the bottom edge of a planar disk.
Claim 2
Dependent Claim
157 words
A disk protector/holder comprising: a housing formed of rigid material having spaced top and bottom major wall surfaces, opposed side walls, a closed bottom edge and an open top end; a first outer edge of the bottom wall surface adjacent the open top end extending outward a short distance beyond a second outer edge of the spaced top wall surface adjacent the open top end, the first and second outer edges of the top and bottom wall surfaces adjacent the open top end having inwardly tapering surfaces; a pair of aligned slots formed in the top and bottom wall surfaces adjacent to the first and second outer edges of the top and bottom wall surfaces and extending downward toward the bottom edge and upwardly extending surfaces formed adjacent the bottom edge defining a sharply-angled V-shaped notch between the bottom edge and the top and bottom wall surfaces to securely receive the bottom edge of a planar disk.
Claim 3
Dependent Claim
15 words
The disk protector/holder of claim 1 wherein the housing is formed of a transparent plastic.
Claim 4
Dependent Claim
153 words
A disk protector/holder comprising: a housing formed of a rigid, transparent plastic material, having spaced top and bottom major wall surfaces, opposed side walls, a closed bottom edge and an open top end; a first outer edge of the bottom wall surface adjacent the open top end extending outward a short distance beyond a second outer edge of the spaced top wall surface adjacent the open top end; the first and second outer edges of the top and bottom wall surfaces having inwardly tapering surfaces; an internal, outwardly tapered, V-shaped notch formed between the top and bottom wall surfaces adjacent the bottom edge of the housing and extending upwardly therefrom to securely receive the bottom edge of a disk; and a pair of aligned slots formed centrally in the top and bottom wall surfaces adjacent to and extending downward from the first and second outer edges of the top and bottom wall surfaces.
Claim 5
Dependent Claim
