Abstract: A compact disc (CD) package formed from a unitary paperboard blank. The package is relatively long and stiff in its pre-purchased form and is readily foldable widthwise only after purchase. To permit folding after purchase, any outer wrapping is removed and the purchaser pulls a tear strip to rip away two of three layers of paperboard spanning the width of the package. This removal permits relatively easy folding of the remaining paperboard layer. The package yields both the desired pre-purchase larger size to permit desired graphics and also inhibits shoplifting. The lesser size of the package after folding facilitates storage by the purchaser. The blank of FIG. 1 includes a first pair of panels (20, 22) in a first row, a second pair of panels (30, 28) in a second row, and a third pair of panels (14, 12) in a third row. The panels of the first pair are joined by a foldable joint (46). The panels of the second pair are joined by a first frangible connection in the form of a tear strip (40).

Glue is applied to the end section of the sheet containing the cut out and that section is folded over and glued to the center section of the sheet, thus forming a pocket sized to receive one half of a compact disc. The semicircular tab is sized to cover that portion of the compact disc surrounding the hole in its center so that a plastic rivet passing through the semicircular tab, the hole in the disc and the center section of the sheet of card stock will secure the disc within the folder.

Abstract: Envelopes are a cost-effective storage means for Compact Discs. However, special problems arise with respect to the sensitive optical surface. Disclosed is a unique envelope/cushion configuration which can be used to minimize or, to elmininate almost entirely, abrasion and chafing, depending on the exact manner of use. A special thin cushion that combines the qualities of surface softness with an underlying stiffness, shares the envelope with the disc. In the preferred usage, disc and cushion are inserted or removed simultaneously, so that no relative movement or chafing takes place between them, and the disc does not contact the rear wall of the envelope. Buckling of the otherwise thin cushion is controlled by its stiffness, by low friction, and by the confined space between envelope wall and disc.The envelope may be designed with greater fullness than usual since the cushion expands and stabilizes the disc, once released within the envelope, so that access is greatly improved.
