Abstract: A packaging unit includes a carton having top and bottom surfaces and side walls extending between said top and bottom surfaces. The unit further includes molded pulp fiber bottom and top trays, with each tray defining a plurality of securement chambers. The unit further includes a self-adjustable, middle dunnage including a main body disposed between the molded fiber bottom and top trays. The main body includes a plurality of holes extending through the main body and a plurality of slots extending from a perimeter of each of the holes to define a plurality of self-adjustable tabs surrounding each of the holes. The middle dunnage further includes a first plurality of foldable flaps extending from the main body towards the bottom surface and a second plurality of foldable flaps extending the main body towards the top surface of the carton.

Abstract: An improved flexible manufacturing process for making molded fiber products uses a molding machine provided with a large number of ports for mounting a variety of molds. Quick release mold attachments permit rapid changeover of production output. The molds used are designed to have a predetermined total height, and platen stops maintain this design separation during transfer of the molded product. An expanded stock chest is provided to permit a higher pulp usage rate. Separate positive air supply lines are provided for the different transfer mold sites. Using these separate lines, a novel air volume and flow control method is provided to control the volume of air applied to release products from transfer molds, permitting manufacture of a variety of complex structures. The air flow controls permit control of both the rate of flow and the duration of the selected rate of flow of positive pressure air, thus providing total volume control.

Abstract: New molded pulp and molded fiber structures provide interior package cushioning to protect products shipped in a package. The molded pulp fiber interior package cushioning (IPC) structure defines a cavity for receiving and holding a product to be shipped. The IPC structure incorporates a plurality of structural ribs in the form of elongate hollow ridges molded in the IPC structure and extending between different locations for reinforcing the IPC structure between the locations. The IPC structure comprises intersecting ribs extending in at least two orthogonal directions or axes.
