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.
