Abstract
Abstract A container for storing a tape cassette of the type having a pair of spaced tape reel hubs. Each hub has a bottom wall and a cylindrical sidewall which define a recess in the hub. The storage container includes enclosure means for receiving and enclosing a cassette in the container. Toggle pairs are mounted on a bottom wall of the storage container and project into the hub recesses through an aligned access opening formed in a bottom wall of the tape cassette upon placing the cassette into the container. The toggle pairs are engaged by the bottom wall of the tape reel hub upon placement of a cassette into the storage container and move outwardly toward an expanded position and into engagement with the cylindrical sidewall of the reel hubs to prevent rotation of the hubs and resultant unwinding of and possible damage to the tape contained thereon. Pairs of inner and outer concentric annular members are formed integrally with the bottom wall of the storage container and encircle the toggle pairs and are located to project through the access openings of the cassette. The outer annular member engages the bottom wall of the cassette to limit lateral movement of the cassette and the inner member enters the hub recess and engages the toggles to prevent the toggles from moving beyond their expanded position.
