ABSTRACT:
A hardened load carrying device includes a unitarily constructed container for holding the load. The container has an opening which is partially bordered by a slot that includes opposed crooked thumbs which project into the channel of the slot. A door for covering the opening of the container has a pair of opposed crooked fingers which are attached along part of the edge of the door to establish a bite. To enclose the load in the container the bite of the door is slidingly received into the slot bordering the opening to cover the opening and engage the crooked fingers of the door with the crooked thumbs of the slot. In an alternate embodiment the crooked thumbs of the slot are replaced by opposed lips which extend inwardly to establish a T-shaped or rounded slot, and the crooked fingers and the door are replaced by a flange which is slidingly received into the T-shaped or rounded slot. Any joints which are established between panels of the container are reinforced using a double thickness of material. Further, the panels can include reinforcing fibers which extend from one panel to another with the fibers oriented substantially parallel to the joint between the panels. In response to an explosive blast inside the container, the bite on the door interlocks with the slot on the container to grip the bite with the slot. Together, this action and the reinforced joints with reinforcing fibers resist a rupturing of the load carrying device.
