  • Interlocking stackable container storage system
    Patent number: 5699925
    Abstract: A portable plastic container has a tapered tongue on a lid top wall arranged for positioning within a tapered groove of a similar container bottom wall for vertically stacking a selected quantity of containers in an interlocking arrangement. Interlocking the containers permits opening of any container without the need foe rearranging and restacking. For interlocking one container to another, the bottom groove of one container is forced into the top tongue of a similar container. A snapping sound is heard as the tongue passes through a slightly smaller groove opening to its seated position within the groove, thus providing seating feedback and assurance to the user that the containers are properly interlocked.
