An external protective shell shipping container into which is loaded a tightly closed primary container for dangerous materials. The protective container is designed to withstand crushing and impact loads in excess of those anticipated in the event of accident, and is also so designed that cracking or breaking of the external shell is taken into account to provide a part of the energy absorbing container design. The external contouring of the container shell avoids sharp corners and provides rounded and sloping surfaces for optimum shock load distribution. The illustrated container is for a long narrow load supported on shock mounts in a free float position within the shell container, the support points being inward from the ends which cantilevers the ends of both the outer shell container and the interior container. A special controlled crush structure is incorporated into the ends of the shell container, and special external contouring provides for ease of handling by fork lift vehicles. The shell container is made of identical top and bottom molded fiberglass half sections secured together after installation of the interior load into the bottom half section. Molded into the shell container sections are vertical detents for stabilization of a number of the shell containers when stacked to prevent relative shifting.

A protective container for holding an object to be protected from damaging impact, comprising in combination, (a) a hollow top section (b) a hollow bottom section comprising a pair of colinearly spaced apart pan shaped end sections each having a base wall and end and side walls and at least one pan shaped central section colinear with said end sections, each end section being joined to said at least one central section by a generally U-shaped trough section, said at least one central section and trough sections each having a base wall and side walls and the pan sections walls being absent at the junctures with the trough sections so that said bottom section is open from one end wall to the other between the side walls, the base walls of at least said end sections being coplanar at a first level and the base walls of said trough sections being coplanar at a second and higher level, whereby when said bottom section is seated flatwise on an underlying surface there exists a vertical clearance between the surface and the base walls of said trough sections, (c) shock absorbing means secured within said bottom section to which the object to be protected is securable in a free floating position, (d) shock-absorbing end structures at opposite ends of and within said container positioned to closely face each end of the object to be protected, and (e) means for fixedly securing said top and bottom sections together to form an enclosing protective shell.
