Abstract

See full text

A book simulating holder or album for cassettes and the like has a cover with front and rear flaps connected by a wide flexible spine with complementary interfitting trays on the inner faces of the flaps and, if desired, a pocket forming strip overlying the cover secured to the bottom and side edges thereof. The wide spine bows outwardly into an attractive closed book front end and tightens the pocket forming strip when the trays are in their stacked closed position. The trays are formed from a single sheet of plastics material and a portion of this sheet between the trays overlies the spine of the cover. Stiffeners such as cardboard are sandwiched between the bottoms of the trays and the flaps of the cover to rigidify the structure. The cover is also a single sheet of plastics material bonded around its marginal edges to the molded tray sheet and the pocket forming strip is simultaneously bonded to the cover. A projection on the bottom of the cassette receiving tray snugly receives the hub of a cassette tape reel. The pocket provided by the overlying strip on the cover may receive the rental or purchase strip for the cassette, while the portion of the pocket overlying the spine may receive a tab identifying the contents of the holder.
