  • Patent number: 5110037
    Abstract: A container especially of the palletized type, made of a single rectangular sheet of fiber board or the like in which the sheet is cut inwardly at its four edges to provide four panels that make up the ends and sides of a box-like structure leaving the uncut portion as a rectangular of smaller but similar shape. In addition to the four panels, the cutting operating provides four corner panels separated from the other panels but integral with the bottom. These corner panels are folded beneath and lie flat-wise against the bottom to give the bottom a double thickness. In addition, portions of the folded-under corner parts project laterally beyond the periphery of the box-like structure to provide a peripheral lip serving as a stop for a tubular cover element that is ultimately slipped over the structure for shipping.
