A container having walls, one having a projection including a hook and an exterior surface opposite the hook having an external contact location, the hook extending away from the contact surface, the contact location disposed interiorly of the hook. The container includes a door, and a latch coupled to the door by a spring. The latch comprises a catch and a binding arm, and has a contact surface positioned to fit the projection between the catch and contact surface. The latch has a locked position in which the catch and hook maintain the door in the closed position, and an unlocked position in which the door is movable. The spring biases the latch into the locked position. Sufficient pressure on the latch overcomes the biasing to achieve the unlocked position, to allow the open position to be attained. When in the locked position, the contact surface faces the contact location.
