Abstract: A multi-ply paperboard container for use as a bulk material bin has elongate rectangular cross-sectioned tubular inner and outer shells having walls that are spaced apart from one another. Rectangular panels, having a width less than the width of the walls of the shells, are located between and adhesively bonded to each overlying pair of walls. Thus, gaps are formed between the inner and outer shell at each corner of the container. The corners of the inner and outer shells are crushed to provide wide soft corners.
