  • Cassette tape holder
    Patent number: 5431281
    Abstract: A cassette tape holder for preventing a cassette tape from unwinding during transportation that is of minimal size so that a large number of cassette tapes may be stored in a small space. The cassette tape holder includes a protective plate with two upward projections that engage the reels of the cassette tape so as to prevent their rotation. The cassette tape holder may then be used in place of a conventional, fully enclosed cassette container to lessen the amount of space needed to store and transport cassette tapes.
