a generally cubical container with a vertical open front selectively closed by a removably attachable hinged cover , spaced aligned parallel slots on the upper and lower walls inside the container to receive floppy discs standing on edge in the slots , the cover having stub shafts to slide into and seat in a first pair of grooves on the outside of the container to close the container or alternatively to slide into and seat in a second pair of grooves to form a support base for the container to provide a slight downward inclination from front to rear to maintain the discs in the container by gravity and to facilitate insertion of discs into the container .
