A composite container includes an outer metal or plastic container body having relatively rigid side, bottom and top walls, with the top wall having a centrally located aperture for insertion and removal of an inner container in the form of a thin, flexible liner or bladder. The inner liner or bladder includes a relatively thin peripheral side wall and bottom wall, and a relatively thicker upper portion including an integrally formed pour spout. The side wall and bottom wall of the outer container body provide substantially full surface support for the side and bottom walls of the inner liner. The pour spout is provided with a peripheral groove which may be snap fit within the aperture formed in the outer container after the major portion of the liner or bladder has been collapsed and inserted into the outer container through the aperture. The pour spout itself has a thin peripheral upper portion which allows the spout to be collapsed to an inoperative position, with the major portion of the spout being located beneath the top wall of the outer container, to facilitate shipment and vertical stacking. Suitable closures may be provided for closing the otherwise open upper end of the pouring spout.
