Abstract
A new and improved book-style cassette holder is provided including a spine portion provided with stay-flat supporting features. The cassette holder includes a cover with front and rear flaps connected by a flexible spine portion. Complementary interfitting trays are provided on the inner faces of the flaps which may be stacked together in a closed position to define a cassette-receiving cavity. The spine portion is provided with a spine liner portion including number of raised protrusions which abut the tray portions in a closed position to maintain the spine portion in a taut condition. A series of spaced strut supports are defined between the protrusions which are effective to maintain the spine portion of the holder in an attractive, readable stay-flat condition in use.
