A self locking cover/bottom for a fibre drum includes substantially perpendicular projections with inwardly tapered portions which, when in registry with notched portions in the fibre shell sidewall, engage the notched portions (which can bend inwardly) such that an airtight seal can be formed for the drum. An optional feature is the provision of a channel in the bottom to accommodate a tine of a fork lift truck.
