Non-dublicable magnetic disk jacket and method of manufacture

Claim 3

The method of claim 1 wherein said partially assembling and assembling is accomplished by folding said jacket blank along predetermined fold lines.

Claim 4

The method of claim 2 wherein said indicia is hot-stamp transfer printing.

Claim 5

The method of claim 3 wherein said hot-stamp transfer printing spans at least one of said predetermined fold lines.

Claim 6

A jacket adapted to receive a magnetic recording disk and which is partially assembled in that the jacket includes first and second superimposed panels secured to each other and each panel having inner surfaces adjacent each other and outer surfaces, the improvement comprising: an embossment in at least said first panel recessed into said inner surface and raising said outer surface, the second panel not including a corresponding embossment recessed into said outer surface and raising said inner surface in the area thereof opposite the embossment in said first panel such as would occur if said superposed panels were embossed as a laminated structure in said superposed relationship, whereby said disk jacket is distinct from other partially assembled disk jackets formed without a said embossment and may be distinguished from other disk jackets wherein said embossment is added after partial assembly.

Claim 7

A jacket adapted to receive a magnetic recording disk and which is partially assembled in that the jacket includes first and second superimposed panels secured to each other and each panel having inner surfaces adjacent each other and outer surfaces, the improvement comprising: an embossment in at least said first panel recessed into said inner surface and raising said outer surface, the second panel not including a corresponding embossment recessed into said outer surface and raising said inner surface in the area thereof opposite the embossment in said first panel such as would occur if said superposed panels were embossed as a laminated structure in said superposed relationship, whereby said disk jacket is distinct from other partially assembled disk jackets formed without a said embossment and may be distinguished from other disk jackets wherein said embossment is added after partial assembly.

Claim 8

A jacket according to claim 5 wherein said first and second panels both include embossments recessed into said inner surfaces and raising said outer surfaces.

Claim 9

A jacket according to claim 5 wherein said second panel is flat adjacent said embossment in said first panel.

Claim 10

A jacket according to claim 5 wherein said embossment includes means for identifying the information recorded on the disk.

Claim 11

An improved jacket for a magnetic recording disk, the jacket being the type which is formed from a single sheet of paper or polymeric material including a bottom panel, a top panel and edge flaps extending from the top panel by folding said sheet at a fold line between said top and bottom panels so that said top panel overlies said bottom panel, folding said sheet at fold lines between the top panel and the edge flaps so that said flaps overlie said bottom panel, and securing the edge flaps to the bottom panel, the improvement comprising: printing which crosses at least one of said fold lines, said printing extending from said top panel and around at least one of said fold lines after said jacket is folded, whereby said printing is positioned in an area on said jacket such that said printing cannot be duplicated on a previously formed disk jacket rendering said previously formed disk jacket duplication resistant in that said printing cannot be applied to said jacket after said jacket is folded and said flaps secured.

Claim 12

An improved jacket for a magnetic recording disk, the jacket being the type which is formed from a single sheet of paper or polymeric material including a bottom panel, a top panel and edge flaps extending from the top panel by folding said sheet at a fold line between said top and bottom panels so that said top panel overlies said bottom panel, folding said sheet at fold lines between the top panel and the edge flaps so that said flaps overlie said bottom panel, and securing the edge flaps to the bottom panel, the improvement comprising: printing which crosses at least one of said fold lines, said printing extending from said top panel and around at least one of said fold lines after said jacket is folded, whereby said printing is positioned in an area on said jacket such that said printing cannot be duplicated on a previously formed disk jacket rendering said previously formed disk jacket duplication resistant in that said printing cannot be applied to said jacket after said jacket is folded and said flaps secured.

Claim 13

An improved jacket according to claim 9 wherein said printing crosses said fold line between said top and bottom panels.

Claim 14

An improved jacket according to claim 9 wherein said printing crosses at least one of said fold lines between said top panel and said edge flaps.

Claim 15

An improved jacket according to claim 9 wherein said printing is a hot-stamp transfer printed area.

Claim 16

An improved jacket according to claim 12 wherein said printed area includes means for identifying the information recorded on the disk.
