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. Even when the cushion is left permanently in place, it nevertheless reduces the chafing and abrasion considerably, and augments the improved access which has been provided in the envelope pocket.
Several envelope and cushion configurations are presented which exhibit the concept and which are amenable to generic display and packaging. The construction optimizes cost-effectiveness with respect to such original, point-of-purchase packaging.
