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.

The container (10) has a lid structure (18) comprising two lid panels (20f) and (20t). The first lid panel (20t) forms at least a part of the top wall (14). The second lid panel 20f forms at least part of one of the side walls (16d). When the container (10) is in the erected condition the lid structure (18) can have one of, and be moved between, a closed configuration; top load configuration; and, front load configuration. The front load configuration has two variants. In a first front load configuration the first and second lid panels (20t) and (20f) remain connected to each other and are moved so that they are in a substantial face to face relationship. In the second front load configuration the second lid panel (20f) is pivoted to lie on top of the first lid panel (20t).
