Protective packing with vacuum formed cushions

Abstract

Method of packing an article in a container in which a quantity of loose fill material is introduced into flexible pouches to form cushions, and the pressure within the pouches is reduced to create a pressure differential which compresses the cushions and molds them to a shape corresponding to the interior of the container. The compressed cushions and the article to be packed are placed in the container, with the article between the cushions, and the pressure differential is then eliminated so that the cushions reexpand and fill container. In one disclosed embodiment, the cushions are molded to the shape of the container by placing the uncompressed cushions in a frame having a side wall with a contour similar to that of the container and a lateral dimension greater than the container, allowing the loose fill material within the pouches to flow to the side wall so that the cushions have a shape similar to the interior of the container, and thereafter reducing the pressure to compress the cushions.
