Abstract
Abstract A disc package for enclosing a record disc and which is capable of opening to permit the disc to be withdrawn therefrom for insertion into a disc player comprises a body for accommodating the record disc, a cover, and a cover hinge pivotably connecting the cover to the body. The body comprises a first part adjacent to the cover hinge, a second part spaced away from the cover hinge, and a body hinge pivotably connecting the first and second body parts. A central holding member formed on the first body part is engageable within a center hole formed in the disc when the package is closed around the disc. A peripheral holding member is formed on a side of the second body part remote from the body hinge for gripping the outer edge of the disc. The disc package thus can be moved between a closed position wherein it securely grips, encloses and protects the disc and an open position wherein the disc is free of the cover, of the first body part and of the central holding member and is held only by the second body part, including the peripheral holding member, so that it is easily inserted into a disc player.
