  • Patent number: 6722560
    Abstract: A bulk box of corrugated cardboard has a readily repulpable water vapor barrier material incorporated in the outer liner, increasing the resistance of the box to penetration by moisture in humid conditions, and especially reducing hysteresis effects in conditions of cyclic humidity. The box has increased strength and bulge resistance, and achieves performance equally as good as or better than a conventional box without the water vapor barrier, while at the same time enabling less pulp fiber to be used in the construction of the box.

  • Patent number: 6588651
    Abstract: An octagonal bulk bin of corrugated paperboard has opposed parallel side walls spaced a predetermined distance apart and opposed parallel end walls spaced a predetermined distance apart. The side and end walls are joined by diagonal corner panels. The diagonal corner panels are made wider than the corner panels in a conventional bin, and the side and end walls are narrower, with the corner panels and the end walls having approximately the same width, while maintaining the predetermined spacing. This configuration reduces the bulge experienced when product is loaded into the bin. In addition to the wider corner panels, or in lieu thereof, scores may be placed in at least one of the side and end panels to define a line along which controlled and predetermined buckling will take place, if buckling occurs.
