Interlocking stackable container storage system
First Claim
1. A container operable within a storage system having similar containers interlockable in a vertically stacked configuration, the storage system useful in organizing and storing articles, the container comprising opposing top and bottom walls, wherein an upwardly projecting tongue extends from one of the container walls, the tongue having outwardly diverging side walls terminating in a tongue edge portion, and wherein a cavity within the opposing container wall has opposing side walls converging toward a cavity opening for receiving the tongue of an adjoining similar container therethrough and attaching the tongue within the cavity, the tongue and cavity each formed as an annulus extending proximate peripheral top and bottom wall edge portions, the cavity side walls cooperating with the tongue side walls while the tongue is attached within the cavity, the cavity opening being slightly smaller than the tongue edge portion, the tongue and cavity formed from material sufficiently flexible for permitting the tongue edge portion from the adjoining container to be forced through the cavity opening for positioning the tongue within the cavity, thus coupling the adjoining containers in a vertically stacked and interlocked position.

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.

6. A portable container useful with other similar containers for arranging within a stackable interlocked configuration, the container comprising:
-
a lid having a top wall, the top wall having a tongue integrally formed with and extending upwardly from the top wall, the tongue having outwardly tapering opposing side walls terminating in a flexible tongue edge portion; a hollow body having a bottom wall, the bottom wall opposing the lid top wall while the container is in a closed position, the bottom wall having a groove for receiving a tongue within the lid of a similar adjoining container, the groove having opposing side walls converging toward a groove opening for receiving the tongue therethrough, the groove opposing side walls generally cooperating with the tongue side walls, in dovetail fashion, while the tongue of the adjoining container is within the groove, the groove opening being slightly smaller than the tongue edge portion, the tongue and groove formed from material sufficiently flexible for permitting the tongue edge portion from the similar container to be forced through the groove opening for seating therein, the tongue and groove each formed as an annulus extending proximate peripheral top and bottom wall edge portions the groove arranged for engaging the tongue of the similar container for interlocking the containers in a vertically stacked arrangement when the containers are in a closed position, and during operation of the containers to their open position; and hinge means operatively connected between the lid and body, the hinge means hingedly connecting the lid and body when operating the container from a closed position to an open position. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A portable storage system comprising vertically stacked interlockable containers, the storage system comprising:
-
a first container having opposing top and bottom walls, wherein an upwardly projecting tongue extends from one of the container walls, the tongue having outwardly diverging side walls terminating in a tongue edge portion, and wherein a cavity within the opposing container wall is defined by opposing side walls converging toward a cavity opening for receiving the tongue therethrough and attaching the tongue within the cavity, the tongue and cavity each formed as an annulus extending proximate peripheral top and bottom wall edge portions, the cavity side walls generally cooperating with the tongue side walls while the tongue of the first container is attached within the cavity of a second container, the second container similar to the first container, the cavity opening being slightly smaller than the tongue edge portion, the tongue and cavity formed from material sufficiently flexible for permitting the tongue edge portion from the first container to be forced through the cavity opening of the second container; and a second container similar to the first container, the second container vertically stacked in an adjoining arrangement with the first container, the second container cavity receiving the first container tongue for coupling the first container to the second container in an interlocked, vertically stacked position. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
