Abstract: A product is mounted on a support pad and suspended on the pad by wrapping a stretch wrapping film around the combination of the pad and product. The borders of the pad extend beyond the borders of the product so the package containing the product can be stood on edge, but the edge of the product is spaced away from the surface on which the package is stood. The borders of the pad also include notches on the top and bottom of the pad that receive the stretch wrapping film away from the borders of the pad and closer to the product. Thus the product, secured to the pad, is suspended away from that surface. Multiple packages can be packed into a shipping container and the loaded container can be lifted and transported by a lift truck with lifting forks received in passageways formed in the container by notches in the bottom edges of the support pads. The pads and containers are made of die-cut corrugated fiberboard material although other material could be used.

Abstract: A thermally insulated cup is formed from a single-walled paper or plastic inner cup and an insulating outer wrapper. The insulating outer wrapper comprises a paper base sheet or outer sidewall blank, optionally printed on one side, and a corrugated paper or foamed plastic insulating insert. The insulating insert is similar in shape to the outer sidewall blank but smaller in size. The insert is glued in a centered position to the non-printed side of the sidewall blank to form a two-layered insulating wrapper. Less than 20% of the area of the insert is glued to the base sheet. Specifically, no glue is applied to the area adjacent to the cut side edges of the insert, and as such these edges are not attached to the base sheet. The wrapper is then wrapped around the single walled inner cup. The side edges of the base sheet of the wrapper overlap and are sealed directly together to form a side seam. The side seam is itself adhesively secured to the side wall of the inner cup.

Abstract: A product vulnerable to damage during shipping, such as an automobile windshield glass, for example, is mounted on a support pad and fixed onto the pad by wrapping a stretch wrapping film around the combination of the pad and glass. The borders of the pad extend beyond the borders of the glass so the package containing the glass can be stood on edge, but the edge of the glass is spaced away from the surface on which the package is stood. Thus the glass, secured to the pad, is suspended away from that surface. Multiple packages can be packed into a shipping container and the loaded container can be lifted and transported by a lift truck with lifting forks received in passageways formed in the container by notches in the bottom edges of the support pads. The pads and containers are made of die-cut corrugated fiberboard material although other material might also be used in the practice of the invention.

The printed paper is then continuously applied to a surface of cellulosic substrate and bonded to the substrate, preferably through use of starch as an adhesive, to provide a laminated product. The laminated product is then die cut to the desired shape, folded and glued into the configuration of a box or container. A layer of water absorbent, cellulosic fiber material can be bonded to the inner surface of the substrate to prevent moisture from the contained product from seeping outwardly through the substrate to the printed paper.

Abstract: Methods and apparatus are described for reducing damage to items shipped in corrugated boxes, and for reducing damage to the boxes themselves and the packing material within them. Damage is limited by adding one or more planar damped panels to a box for redistributing kinetic energy absorbed by the box when it is subjected to characteristic shipping shock and vibration. Efficient coupling of redistributed kinetic energy to resilient packing material within a box allows the use of relatively less resilient padding surrounding shipped items, thus allowing use of a relatively smaller box to obtain an acceptable level of protection. Planar damped panels also limit shifting of the item(s) to be protected by acting as damped variable-rate springs.

Abstract: A corrugated plastic box is disclosed. The box is provided with an L-shaped or chair-shaped end panel which can be adhesively secured to a box side panel. The end panel has a lower portion which extends over a relatively great number of box side corrugations, and an upper panel portion which extends over fewer box side corrugations, so as to spread interior box loads across a number of corrugations and inhibit box side bowing. The box sides are also strengthened by providing upper panels which are rolled over along the top edges of the box, the panels are then food or otherwise fastened to the side panels. The rolled-over top edges thus formed strengthen the box, and prevent the entry of contaminants into the otherwise-exposed side panel corrugation flutes.

Abstract: The invention is a shipping container blank whereby all surfaces and edges are sealed by an overlying a plastic film material. A container subsequently made from the blank is rendered highly water resistant. The film material is applied to both sides of the blank and severed from the supply source. The covered blank is then heated above the softening point of the film. The film becomes bonded to the surfaces of the blank and sags around the edges and into any openings so that the film on the two sides of the blank come into contact and are sealed to each other. The edges and any slits and cutouts are then trimmed, as by a die cutter, while preserving the seals along the edges. Containers made by the process can generally be recycled, in contrast to wax or resin impregnated corrugated board.
