Abstract: A bulk container for storing and shipping flowable material in bulk. The container is constructed of inner and outer cartons laminated together and made of corrugated paperboard. The container has side walls with at least one viewing opening for viewing the level of contents of the container, and a closable dispensing opening through which the flowable material may be dispensed. The closable dispensing opening is located in a lower corner of one of the side walls, adjacent to but spaced from the corner, and is closed by a first pour spout flap in the outer carton foldable in a first direction, and a second pour spout flap in the inner carton underlying the first flap and foldable in a second direction. Both flaps are formed by two spaced apart slits in the respective inner and outer cartons, extending parallel to the direction of the flutes of the corrugated paperboard, with the slits in the outer carton in substantial registry with the slits in the inner carton. The flaps, when in their open position, form an opening in the wall adjacent to but spaced from the corner and through which product is dispensed. The viewing opening preferably is formed of two parallel, laterally and vertically offset narrow slots extending parallel to the direction of the flutes of the corrugated material and located within the lower half of the side wall.
