  • Patent number: 7137765
    Abstract: A composite dunnage bag being an elastic inner bag enclosed in a paper outer bag for insertion between stacks of cargo in transit. The mattress shape of the outer bag (when the dunnage bag is inflated) enables the bag to apply a footprint against the cargo walls that is greater than bags of the same length and height of the prior art this is an especially advantageous feeature when the spacing between stacks of cargo is greater than 12 inches.

  • Patent number: 7051753
    Abstract: A valve for an airtight flexible container such as a dunnage bag including a bowl with openings and extending through an opening in the container A flange around the rim of the bowl is heat welded to the container around the opening. One end of a housing is screwed into the rim of the bowl. A cap is removably press fit onto an opposite end of the housing. A spider extending across the housing supports a plug which is spring mounted on the spider and biased to close the lower end of the housing by compressed air in the container. Compressed gas inside the container is released by removing the cap and pressing on the plug to dislodge the plug from its seat on the one end of the housing or by unscrewing and entirely separating the housing from the bowl.

  • Patent number: 6527488
    Abstract: A principal advantage of this composite bag compared to the bags disclosed in the present art using solid ply is improved combination of strength and flexibility. A composite dunnage bag being an elastic inner bag enclosed in a mesh outer bag. The bag replaces the system of state of the art bags plus filler panels which are currently used when the space between pallets is greater than 12 inches. The combination mesh and plastic is sufficiently strong and flexible to permit the bag to apply an 80% footprint against the cargo walls.

  • Patent number: 6386247
    Abstract: A valve for a dunnage bag including an inner part having a flange that is laminated to the inside surface of the bag and an outer part having a flange that is laminated to the outside surface of the bag providing that the bag can be inflated/deflated by air passing through both parts and a hole in the bag. The outerpart is a bowl which is stretched away from the bag when the bag is being inflated and which collapses against opening in the inner part to seal the bag and prevent air loss.
