Abstract: An inflation device for inflating containers having a body with an air channel therein being in the form of a venturi tube. A first inlet is provided in the body, being in communication with the air channel, to allow compressed air to flow into the air channel. An outlet is provided in the body, being in communication with the air channel, to allow the air to exit the air channel for inflating a container joined to the outlet. A second inlet is provided in the body, being in communication with the first inlet, to allow ambient air to be sucked into the air channel as a result of the compressed air flowing in the air channel and passing through the venturi tube. A self-closing valve and sensor means are also provided.

Abstract: The invention discloses a dunnage bag for securing loads, which includes an inflatable dunnage bag for 12 to 40 inch voids between load to be secured and consisting of a gastight polyethylene inflatable bladder provided with an inflation valve; and a reinforcing sleeve made of at least one ply of paper, the sleeve having a first opening and a second opening, and the reinforcing sleeve being folded to form at least one substantially rectangular end to close off at least one of the openings; and in which at least 50% of its exterior surface area is in contact with a load to be secured.

Abstract: A dunnage bag for securing loads is provided which includes an inflatable dunnage bag for 12 to 40 inch voids between load to be secured. The bag consists of a gastight polyethylene inflatable bladder provided with an inflation valve and a reinforcing sleeve made of at least one ply of a suitable material. The sleeve has a first opening and a second opening. The sleeve is folded to form at least one substantially rectangular end to close off at least one of the openings. At least 50% of an exterior surface area of the dunnage bag is in contact when placed between two loads to be secured or when placed between a support and a load to be secured.

Abstract: The invention discloses an inflation valve for inflating containers, which includes a housing including a first opening at a first end and a second opening at a second end, the housing being adapted to be secured to a container at the second end, and adapted to receive a gas filling nozzle at the first end; a disc adapted to close-off the second opening; and a resilient member associated with the housing and the disc, and being adapted in its inoperative position to hold the disc against the second, opening to close it off, and when gas is released by the filling nozzle into the housing to allow the disc to move away from the second opening against the action of the resilient member.
