1. An interbox connector for securement of a top container to a bottom container, the top container having a corner casting and the bottom container having a corner casting, the interbox connector comprising:
a plate configured to be positioned between the corner casting of the bottom container and the corner casting of the top container prior to the top container being stacked on the bottom container;
a first latch extending upwardly from the plate, the first latch being configured to be disposed in the corner casting of the top container in an unlatched position; and
a second latch extending downwardly from the plate, the second latch being configured to be disposed in the corner casting of the bottom container in an unlatched position;
wherein placement of the top container on top of the bottom container causes the second latch and the first latch to both automatically rotate into a latched position and secure the top container to the bottom container and wherein removal of the top container from the bottom container causes the first latch and the second latch to automatically rotate and unlock the first latch from locking engagement with the corner casting of the top container and subsequently unlock the second latch from locking engagement with the corner casting of the bottom container.
