ABSTRACT:
The enclosure comprises a base having perimetric side walls and a cap having coaxial perimetric side walls. The cap and the base have a major axis and a minor axis. A longitudinally extending locking bar is rotatably mounted in the center of the cap and has a length slightly greater than the minor axis of the base. The cap and base have coextensive slots formed in opposing walls which slots start at points on opposite ends of the minor axis and extend in the same direction peripherally about the cap and base for approximately 45.degree.. The portions of the slots on the opposite ends of the minor axis have a thickness which is approximately twice the thickness of the locking bar. The remainder of the slot has a thickness which is approximately equal to the thickness of the locking bar. In this manner, when the locking bar is rotated into the slot, it will proceed through the single thickness area and be biased into the double thickness area where it will be held against further rotation. This produces a tight locked enclosure wherein the manner of reopening is not readily apparent.
