<p>A hardened load carrying device (10,100,150) includes a unitarily constructed container for holding the load. The container (10,100,150) has an opening (14,106) which is partially bordered by a slot (40,136) that includes opposed crooked thumbs (46,48) which project into the channel of the slot (40). A door (28,112) for covering the opening (14,106) of the container has a pair of opposed crooked fingers (46,48) which are attached along part of the edge of the door to establish a bite. To enclose the load in the container (10,100,150) the bite of the door (28,112) is slidingly received into the slot bordering (40) the opening to cover the opening and engage the crooked fingers (46,48) of the door (28,112) with the crooked thumbs (58a,58b) 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 (40b), and the crooked fingers and the door are replaced by a flange (61) which is slidingly received into the T-shaped or rounded slot. Any joints which are established between panels (152,154,156) of the container (150) are reinforced using a double thickness of material. Further, the panels can include reinforcing fibers (160,166,168) which extend from one panel to another with the fibers oriented substantially parallel to the joint (158,160,162) between the panels. In response to an explosive blast inside the container (10,100,150), the bite (44) on the door (28) interlocks with the slot (40) on the container (10,100,150) to grip the bite (44) with the slot (40). Together, this action and the reinforced joints (158,160,162) with reinforcing fibers (160) resist a rupturing of the load carrying device. <IMAGE></p> |
