ABSTRACT:
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 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. The plastics sheet is vacuum molded to the desired tray contours. 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.
