Abstract: An intermediate bulk container (IBC) system comprising a base and walls, and having an interior space. The system comprises a drain in the base or in a wall, a liner bag having a liner bag drain couplable to the drain in the base or in a wall, and a door coupled to the wall by a hinge and shaped to cover an opening in the wall. The opening extends from a top of the wall. The hinge is coupled to the door to allow the door to rotate into the interior space. A stop prevents the door from rotating beyond the wall. The system may be used by rotating the door into the interior space to expose the opening, reaching through the opening and operatively coupling the liner bag drain at the drain in the base or in a wall, and rotating the door to cover the opening.
