Abstract
A storage and transport drum including a removable cover and a liner bag assembly. The liner bag includes bottom, side, and top walls and a collar surrounding an opening in the top wall. The collar includes a groove for receiving a retainer ring that fits within a groove in the side wall of a drum cover fitting. An exterior plug is provided for the drum cover fitting and an interior plug for the bag collar. The fitting, the collar, and the retainer ring are arranged such that the retainer ring retains the collar against unintentional separation relative to the fitting, but the bag and collar may be intentionally separated by pushing the bag into the drum when desired.
