  • Storage drawer with retained partitions
    Patent number: 4436215
    Abstract: A storage drawer is disclosed made of a rugged plastic material rather than metal and in which the removable partitions in the drawer are held in place by a wedging action provided by tapering slots on each side. The partitions will not fall out when the drawer is upside-down to remove the contents, but the partition may be easily removed by pulling it out without the necessity of overcoming latching or locking mechanisms.
