ABSTRACT:
The invention provides a vacuum formed cassette album having front and rear covers connected by a spine. The covers and spine are formed from a stiff, self-supporting thermoformed tray sheet extending the height and breadth of both the front and rear covers and across the spine area. A soft cover sheet, formed for example from supple plastic, is sealed to the tray sheet along its edges. At least a pair of parallel, vertically disposed, laterally spaced apart vacuum formed channels are provided in the tray sheet at the edges of the spine and extending to the top and bottom edges of the tray sheet to define fold lines between the spine and the covers. The channel-form hinges are substantially uncompressed. They are of uniform thickness throughout and of the same thickness as the surrounding material of the tray sheet so that when the album is closed the soft cover stock is drawn onto the hinges to provide a smooth contour around the outside edge of the adjacent channel-form hinges which are covered and enclosed by the smoothly contoured cover stock material to present a neat, tailored appearance.
