Abstract

A container for bulk flowable materials in capacities greater than 500 litres, comprising a tubular inner member adapted to withstand pressure from the contained material as hoop stress in the tubular inner member and therefore to prevent bulging of the container walls, and a co-axial outer polygonal section member, the same length as, or larger than, the inner member, designed to withstand column loading from a plurality of similar containers stacked one on top of the other. The container is typically provided with end caps and a liner bag having an outlet spigot. The outer member is preferably octagonal and constructed from multi-wall corrugated fibreboard.
