Abstract
A bung-type drum or barrel has an internal liner formed by a removable insert container which can be introduced through one of the bung openings and has tubular formations of the synthetic resin foil which can be held in or drawn into the bung openings and there can be held by retaining elements. The liner conforms to the interior of the drum and, for the removal of residues, can be withdrawn through a bunghole and replaced.
