Description

"A COMPACT DISC CONTAINER"

BACKGROUND OF THE INVENTION

1. Field cf the Invention - The present invention pertains to a package, and more particularly, pertains to a package for a digital audio disc as used in compact disc players.

2. Description of the Prior Art - Prior art disc packages have failed to provide a package which is easy to accessibly open by an individual. The prior art packages have usually been extremely small in size relating to the smallness and thinness of the digital disc. Consequently, it has taken a certain amount of finger dexterity to open the package accordingly. Another problem of the prior art has been the surface for gripping the disc, the components of which have failed in time to grip the disc due to normal wear and tear, and which usually have been extremely large in size. Finally, the prior art devices do not have a sufficiently high center disc support nor a disc alignment ring which would also protect the surface of the disc which contained the data regions.

The present invention overcomes the disadvantages of the prior art by providing a digital audio disc package

SUBSTITUTE SHEET which is easy to open, includes a small disc gripper area, and has a substantial center disc support and disc alignment ring, in addition to being a state of the art package for containing the disc. SUMMARY OF THE INVENTION

The general purpose of the present invention is to provide a digital audio disc package for supporting a digital audio disc.

A disc 100, as illustrated in FIGS. 2 and 3, slides under the disc gripper 56 when the large bottom member 16 is at a finite angle with respect to the small bottom member 14. Then, the large and small bottom members 16 and 14 are gripped by one's fingers and rotated about the living hinge 18 so as to be in an identical plane with respect to each other, whereupon the disc 100 is aligned in the final closing operation by the edge guide members 90 and 92, the disc then being engaged by the disc

SUBSTITUTE SHEET alignment ring 22, seats on center disc support 20 and is supported also upon the disc support edge 30. Afterwards, the cover 12 can be rotated about the hinges 34 and 26 and lock into position over the small bottom member 14 and the large bottom member 16 which, using locking hinges 44 and 46, which were previously locked together in a rigid fashion during disc insertion into the package. The small bottom member 14 is in frictional engagement to the large bottom member 16 and the transparent cover 12 is in frictional engagement to the small bottom member 14. The mated small and large bottom members form a substantially circular area for encompassing the disc.

To utilize the disc contained within the package 10, one merely grasps the underside overhang area of finger grip grooves 76a and 76b to loosen and pivot the cover 12 clear of bottom members 14 and 16. Then, with simple application of light diverse pressure upon small and large bottom members 14 and 16, the locking hinges 44 and 46 disengage themselves allowing the members to be rotated to approximately a 90° angle from each other about the living hinge 18, thus disengaging the disc alignment ring 22 leaving the disc 100 contained by disc gripper 56 ready for insertion into a compact disc player.
