A common metal drum is used in an upside down orientation and has a drum liner system installed through the designated bottom surface thereof. The drum liner system comprises an adapter mounted through the designated bottom surface. The adapter has a relatively large opening through which the liner is easily installed and the drum can be easily inspected and repaired. In another aspect, the adapter and a liner collar share a common thread, and a cover is mountable over this common thread. The thread portion on the liner collar is selectively movable relative to the thread portion on the adapter to cause a locknut effect therebetween and to retain the cover on the adapter and the liner collar. In a further aspect, a drum liner is bonded to the liner collar and is folded inside the liner collar. A hermetic wrapper is stretched around the liner collar and the drum liner. This drum liner package is particularly advantageous for being shippable to a user in an aseptic condition and for being maintainable in this condition prior to use.
