Abstract

Abstract A load bearing device for protectively packaging articles. The load bearing device interfaces with the corner of a shipping container on an outer surface and a corner of the article to be protected on an inner surface. The load bearing device may be formed of molded plastic and has the geometric contour of a pyramidical envelope. In one embodiment, the load bearing device includes a plurality of fluted elements fashioning a series of truncated triangular pyramids formed one into the other. The apices of the truncated pyramids consecutively increase in height in straight line fashion along the pyramid envelope to a centroidally positioned triangular pyramid.
