Abstract
Abstract A disk jacket is disclosed, the jacket having an outer envelope and an inner liner and being closed around three edges and opening outwardly along a top edge. A pair of outwardly curved elastic plates are secured between the outer envelope and the inner liner along opposite sides of the opening to cause the top edges of the opposed side walls of the jacket to be concave, whereby the mouth of the jacket is normally open. An interlocking latching mechanism is placed in the middle of the jacket opening to permit the jacket to be closed, and a covering, or lid, material is secured to the inner surface of the jacket liner along the upper edge thereof, the covering material being substantially the same thickness of a disk so as effectively to seal the opening of the jacket when it is secured in the closed position by the interlocking latch mechanism.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
120 words
A disk jacket comprising an envelope for receiving an disk, said envelope having first and second opposed walls closed along three corresponding edges and having corresponding first and second upper edges defining an opening: first and second normally outwardly curved elastic plates secured along the length of said first and second upper edges, respectively, of said first and second opposed walls to seaparate said walls and to hold the jacket normally open at said opening, first and second interlocking means secured to said first and second upper edges, respectively, for holding said curved elastic plates together and thereby holding said opening closed; and covering means secured along said first and second upper edges to seal said opening upon closure thereof.
Claim 2
Dependent Claim
120 words
A disk jacket comprising an envelope for receiving an disk, said envelope having first and second opposed walls closed along three corresponding edges and having corresponding first and second upper edges defining an opening: first and second normally outwardly curved elastic plates secured along the length of said first and second upper edges, respectively, of said first and second opposed walls to seaparate said walls and to hold the jacket normally open at said opening, first and second interlocking means secured to said first and second upper edges, respectively, for holding said curved elastic plates together and thereby holding said opening closed; and covering means secured along said first and second upper edges to seal said opening upon closure thereof.
Claim 3
Dependent Claim
35 words
The disk jacket of claim 1, further including an inner liner secured within said outer liner and having top edges secured to corresponding top edges of said envelope by way of said curved elastic plates.
Claim 4
Dependent Claim
20 words
The disk jacket of claim 2, wherein said interlocking means is secured to the inner surface of said inner liner.
Claim 5
Dependent Claim
24 words
The disk jacket of claim 3, wherein said curved plates are secured between corresponding upper edges of said outer envelope and said inner liner.
Claim 6
Dependent Claim
45 words
The disk jacket of claim 2, wherein said interlocking means is secured midway along the lengths of said first and second curved plates and at the middle of the opening of said jacket, said interlocking means securing said elastic plates against their normal outward curvature.
Claim 7
Dependent Claim
