ABSTRACT:
A cardboard box, made from a single cardboard blank, has a slanting upper surface to enable the contents of the box to be clearly seen. Opposed interlocking points are formed along the slanting side edge. When one such box is inverted and stacked on another, the interlocking points come into abutment and keep the boxes from sliding apart. As a result, boxes with truncated triangular cross-section may be stacked and shipped as if they were rectangular in all dimensions.
