Packaging for multiple media discs

1. A package for holding media discs, comprising:

a stack of disc-holding trays including at least a top tray and a bottom tray, each tray in the stack having means for receiving and holding a media disc thereon, each tray in the stack having a hinge edge and an opposite edge, the hinge edges of the trays being aligned with each other, and a flexible hinge member affixed to the hinge edges, the flexible hinge member hinging the trays to each other at the hinge edges;

an enclosure comprising a base, a spine and a cover for receiving said stack of disc-holding trays within said base with said hinge edges adjacent said spine and said opposite edges remote from said spine, said enclosure having an open position in which media discs can be inserted onto and removed from the disc-holding trays and said trays can pivot about said flexible hinge member to form a second stack of trays and a closed position in which said cover is pivoted about said spine to enclose the stack of disc-holding trays within said base;

the bottom tray in said stack of disc-holding trays being mounted in said base for pivotal movement about said opposite edge;

whereby, with the enclosure in its open position, as trays are pivoted about said flexible hinge member from said stack onto a second stack, the hinge edge of said bottom tray pivots away from said base when said second stack contains at least one more tray than the original stack.

2. A package, as claimed in claim 1 , including first means on said bottom tray and second means on said base, said first and second means interengaging for mounting said bottom tray for pivotal movement in said base.

3. A package, as claimed in claim 2 , wherein said first means is on said opposite edge of said bottom tray.

4. A package, as claimed in claim 2 , wherein said first means is a part of said opposite edge of said bottom tray.

5. A package, as claimed in claim 2 , wherein said base includes a floor panel and said second means is mounted on said floor panel.

6. A package, as claimed in claim 5 , including wherein said floor panel includes an upstanding wall adjacent the opposite edges of said tray stack.

7. A package, as claimed in claim 6 , wherein said second means is mounted on said floor panel adjacent said upstanding wall.

8. A package, as claimed in claim 5 , wherein said first means is on said opposite edge of said bottom tray and including at least two of said first means spaced along said opposite edge and a corresponding number of second means spaced along said floor panel.

9. A package, as claimed in claim 5 , wherein said first means is a part of said opposite edge of said bottom tray.

10. A package, as claimed in claim 9 , wherein said first means is a slot formed in and extending along said opposite edge of said bottom tray, a portion of said tray remaining below said slot, and said second means comprises means mounted on said floor panel and extending upwardly therefrom, said upwardly extending means having an upwardly opening pivot bore therein, said bore extending in a direction substantially parallel to said opposite edge of said bottom tray and being dimensioned to receive and pivotably retain the portion of said tray remaining below said slot.

11. An package, as claimed in claim 9 , wherein said tray comprises a planar upper surface and a depending flange extending at least along said opposite edge of said planar upper surface, said first means comprising a slot formed along the intersection of said planar surface and said depending flange along said opposite edge, a portion of said slot extending onto said planar upper surface and another portion of said slot extending onto said depending flange, a portion of said depending flange remaining below said slot.

12. A package, as claimed in claim 11 , wherein said second means comprises a pair of generally parallel posts upstanding from said floor panel, said posts being spaced apart at their upper and lower portions a distance at least equal to the width of said depending flange and being spaced apart intermediate their upper and lower portions a distance less than the thickness of said depending flange, whereby the depending flange portion below said slot is inserted into the space between said slots and forced downwardly until said depending flange portion is pressed past the intermediate narrow space between the posts into the space between their lower portions.

13. A package, as claimed in claim 10 , including at least two of said first means spaced along said opposite edge and a corresponding number of second means spaced along said floor panel.

14. A package, as claimed in claim 12 , including at least two of said first means spaced along said opposite edge and a corresponding number of second means spaced along said floor panel.
