This relates to a lined container, preferably of the fibre drum type, wherein the lining is extruded as an open ended tube and is initially adhered to the bottom or end wall of the container to seal the tube after which the tube is first inflated and blown across the end wall and is then blown within the container so as to conform to the interior configuration of the container body. The tube is formed by an extruder, and/or accumulator capable of intermittent extrusion with therebeing relative movement between a die associated with the extruder and the container during the extrusion of the tube, and after the entire interior of the container has been lined, there is associated with the die and the container a mold which upon further extrusion of the tube and the blowing of air within the tube the tube either may be caused to fold around the exterior free end portion of the container so as to form therearound or may be shaped to define a flange which is later draped around the container free end portion. In the case of a fibre drum, the formed or draped portion of the liner protects the metal reinforcing ring in the chime area against corrosion.
