STACKABLE CONTAINER Abstract of the Disclosure An improved stackable container adapted to positively lock with a second container. The container includes a base and a lid for covering a storage space within the base. The base includes a downwardly depending rim having an inner diameter sized to fit over an upwardly extending cylindrical step on the lid of a second container, the downwardly depending rim and upwardly extending step including locking structures for positively locking a base of one container to a lid of another container. The locking structure preferably includes a plurality of multiple thread segments evenly spaced around the lid and base. There are preferably twelve thread segments evenly spaced around the step of the lid and within the rim of the base, the vertical height of the step being relatively small and the angle of rotation to lock the lid and base together is correspondingly small. The present containers are specially suited for holding relatively heavy small objects therein and stacking a multiple of containers together without the stack separating when tilted or inverted.
