A container comprises a tongue on one side and a groove on the other side. The tongue of one container fits into the groove of another container. The combination of the tongue and groove of the containers make it possible so that when two or more of the containers are positioned adjacent to each other, the sides interlock. The container with the tongue and groove can be used as interlocking blocks in combination with other containers also with tongue and groove.
