ABSTRACT:
A flexible intermediate bulk container includes at least one lifting loop and a double base made of two bottom parts that can be direct extensions of sidewalls of the container. The bottom parts have openings positioned directly one above the other, thus forming an opening in the base. In between the bottom parts it is arranged a closure of flexible material with projections on each side of one end. The projections of the closure are fastened to the base by joints or seams. The other end of the closure has a handle. The closure can be made of woven fabric of similar or the same type as that of the container.
