Abstract
A lid and locking system therefor at one end of an ammunition container with an outer shell is made up of a ring fixed on one end of the shell, a lid seated within the ring, a lock spider with the end of its legs taken up in openings in the ring, and a screw, supported by the spider, for forcing the lid against the ring. The lid has a castellated cover on its outer side. The segments of the cover, answering to its castellated form, come to an end in a plane at the end of the locking ring and are somewhat smaller in diameter than the diameter of a circle running through inner ends of ribs on and within the locking ring.
