ABSTRACT:
A packaging system for an appliance which includes a planar bottom board fastened to the appliance base and dimensioned and configured to provide a horizontal lip which projects outwardly beyond the appliance base perimeter, a container sleeve surrounding the appliance and snugly embracing the bottom board perimeter, and a tubular corner post sandwiched between each vertical corner edge of the appliance and the associated vertical internal corner of the sleeve and overlying and supported by the bottom board lip. To prevent a substantial reduction in the resistance of the corner post to compressive loading applied longitudinally thereto when containerized appliances are stacked, the corner post outer wall is provided, in at least the region adjacent the bottom board, with a vertically disposed indentation or bead. Should the corner post overhang the perimeter of the bottom board, a substantial portion of the post cross-section remains within the bottom board perimeter supported by the lip, thereby distributing compressive loads applied longitudinally to the corner post over substantially the entire cross-section thereof, in turn preventing a substantial reduction in resistance of the post to buckling.
