Abstract: A metal reinforcement fitting 10 including a strip 12 curved vertically upward is attached to a bottom 20b of a transportation container 20, and thus upward force can be applied to the bottom 20b. The upward force of the metal reinforcement fitting 10 can suppress downward force of a heavy article housed in the transportation container 20. Accordingly, if the metal reinforcement fitting 10 is attached to the bottom 20b of the transportation container 20 before the heavy article is housed, the bottom 20b can be prevented from bulging. Additionally, even if the bottom 20b of the transportation container 20 has already bulged, instability caused by deformation of the bottom 20b can be improved by attachment of the metal reinforcement fitting 10. Thus the provided metal reinforcement fitting has durability for long-term use of a transportation container.

Abstract: The invention is a method of preventing bulging near a sealed access door in the wall of a cylindrical plastic container. The method comprises a tension-bearing structure which wraps around the container and is forcible held away from the surface by a means which distributes the resulting force over the area of the container wall which is likely to bulge. The resulting force is higher than the force exerted by a tension-bearing structure under the same tension that is not held away from the surface. The distributed load counteracts the hydrostatic pressure within the container that would cause the container wall to bulge.
