Abstract
This relates to a gas and liquid tight corner structure for fibre shipping containers or drums and particularly relates to the provision of a sealing rim on the end unit which is engaged within the corner construction and is compressible so as to maintain a tightening effect on the seal of the corner structure after the corner relaxes under the influence of crimping mechanism. The sealing rim may be tubular in the case of a metal end unit or may be solid in the case of a plastic end unit and the plastic material is resiliently compressible.
