Abstract
Abstract Readily damaged articles are shipped and transported by confining the articles in generally parallel, regular arrangement, applying a compressive force in a direction normal to the force of gravity and restricting motion in a direction generally normal to a plane containing the force of gravity and the compressive force. The method and apparatus of the present invention are particularly suited for the shipment of plastic foam bodies and rectangular containers having low compressive strength.
