Abstract: A nozzle for accelerating filling a container with gas up to a required gas pressure including a barrel having venturi openings in a side of said barrel and a sleeve that, in one position uncovers the tunnels and in another position, closes off the openings. In another version the nozzle further includes a pressure chamber, having a wall coupled to the sleeve. In a contracted position the sleeve is moved by the wall of the chamber to close off the tunnels. In another position of the wall where the chamber is in an expanded position the tunnels are so as to increase the rate of flow.

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.

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.
