Abstract: A bladderless dunnage bag is provided in which the primary material used for construction is a dunnage material based upon a paper substrate in which one or both of its outer surfaces are coated with a resin material that is impermeable to air and is heat sealable. By use of heat sealable coating materials, a center seal and the end seals of the dunnage bag can be formed in a moving process, and the heat-sealable joints or seals are stronger than the paper substrate material itself, since the heat seals are comprised of the coating material being adhered to itself, rather than the use of an adhesive applied to a paper material as in conventional dunnage bags. In a preferred construction, the dunnage material has a resin coating on both the top and bottom surfaces of the paper substrate, and both lap joints and fin joints can be formed by a heat sealable process that adheres the coating materials together, and does not depend upon the paper material for strength.

Abstract: A method of manufacturing an inflatable dunnage bag having a wall construction of two integrally fused layers of thermoplastic polymer, the outer layer of which is a sleeve of strips of woven polymer, the inner of layer of which is a continuous layer of gas impervious polymer. The ends of the sleeve are sealed against the escape of gas. The wall of the bag has a valve for the admittance of gas to the interior of the bag. The bag is formed by deposition of a continuous molten layer of gas impervious polymer to a sleeve of strips of woven polymer, installing a valve for admittance of gas into the wall of the sleeve and forming a gas tight seal at the ends of the sleeve. Deposition of the continuous layer of gas impervious polymer may be a two-step process wherein a molten layer of gas impervious polymer is deposited to one exterior side of the flattened sleeve, then to the other exterior side of the flattened sleeve and the sleeve turned “inside-out”.

Abstract: An inflatable dunnage bag comprises a first inflatable inner bag comprising an inflatable bladder surrounded by a pair of paper plies, and a second outer bag comprising two sets of paper plies disposed upon opposite sides of the first inner bag. The two sets of paper plies comprising the second outer bag are longitudinally offset with respect to each other so as to form flap members on first ends of each set of paper plies which overhang respective second ends of the opposite set of paper plies. The flap members are respectively folded over the second ends of the opposite set of paper plies as single entities and secured thereto by predetermined hot melt adhesive and cold glue bead patterns. The dunnage bag is thus particularly adaptable to being fabricated by automated equipment.

Abstract: An inflatable dunnage bag is comprised of a first and independently sealed bag that is inserted within a paper tube before the tube ends are sealed to form a second, independent bag. The combination of an inner bag within an outer bag provides increased bursting strength compared to similar ply bags created as only a single bag. The combination bag is much easier to construct since at least two plies of paper that are pressed to form the inner bag are no longer part of the bag end folding and sealing process. This is especially true if the outer bags ends are sealed by stitching them together.

Abstract: An inflation and deflation device especially adapted for use with dunnage air bags includes a cylindrical valve body possessing a first end mounted for relative rotation within a hollow interior cylindrical portion of a valve actuator. An internal spring biases a valve seat radially outwardly into engagement with an internal cylindrical side wall portion of the valve actuator. Rotation of the valve actuator selectively aligns air exhaust passages of the valve seat and the valve actuator to deflate an associated dunnage air bag. The valve body includes air passages connecting a compressed air source to the dunnage bag for selective inflation and to allow use of the compressed air source to provide a relatively high velocity air stream across an air passage connected to the dunnage bag to facilitate deflation of the bag by inducing a vacuum.

Abstract: A cargo airbag structure system for use within a cargo bay of a transport vehicle in order to buffer and stabilize loads, such as, for example, large paper rolls or drums, comprises two inflatable bladders disposed in an overlapping disposition with respect to each other within a sealed, expandible, multi-ply paper container. When interposed between the cargo load rolls, the airbag structure conforms to the external contours of the cargo load rolls which serves to not only enable the airbag system to buffer and stabilize the cargo loads, but in addition, the airbag system is stably retained between the cargo load rolls. In order to prevent friction, abrasion, or pinching of the bladders during the inflation process as well as during use of the airbag system when the bladders are disposed in their inflated state, the inflatable bladders are disposed within encasing sleeves which fully envelop the bladders along the longitudinal extents thereof, the opposite ends of the sleeves being open.

Abstract: A dunnage air bag is formed from two rectangular sheets. Each sheet is formed by a polyethylene layer adhesively bonded to a liner board layer. An air valve is mounted through one of the sheets to enable the dunnage air bag to be selectively filled with air. The sheets are disposed in overlying offset relation, with the polyethylene faces of the sheets in contact. A rectangular bladder is created by heat welding the polyethylene layers together, through the liner board layer, in a rectangular heat weld. Offset flaps of the sheets are then folded over on fold lines disposed interiorly of the heat weld and adhesively secured in order to reinforce the bladder and minimize stress on the heat weld. In alternative constructions, the polyethylene layer may be dimensionally smaller than the liner board layer such that a strip of liner board remains exposed along one or more peripheral edges of the polyethylene face of the laminate sheet.

Abstract: An airbag for use in a cargo bay of a transport vehicle for buffering and stabilizing a load, usually large paper rolls or drums, is provided with two inflatable, gas-tight bladders surrounded by a multi-ply paper container.

Abstract: A dunnage bag valve and coupling arrangement comprises a valve stem having a spring loaded valve member which is movable to open a passage through the stem. A pair of circumferentially extending, diametrically opposed slots are formed on opposite sides of the stem. An axially extending opening is provided at one end of each slot for receiving a lug. A pair of lugs are formed on the inner cylindrical portion of a coupling so that the coupling can be pressed onto the stem and twisted, the lugs being introduced into the slot openings and then riding along the circumferential portions of the slots. An air hose is threaded to the coupling so that compressed air can be introduced through the valve stem into the dunnage bag. A fixed post inside the coupling opens the valve member when the coupling is engaged to the valve stem. To prevent rotation of the stem, teeth at the base of the stem engage teeth on the ring of a handle that is held while the coupling is pushed and twisted onto the valve stem.
