Abstract: An inflation device for inflating containers with non-rigid walls such as bags, which includes a body having a venturi shaped air channel. First and second air inlets lead into the air channel, with an outlet being adapted to allow air to exit from the air channel for inflating a container when joined to the outlet. The second inlet is adapted to be closed by a self-closing valve if air does not flow through the air channel. A sensor associated with the body is adapted to detect when a container, such as a bag, joined to the body has been filled to a predetermined degree and then causes the flow of air through the air channel to be interrupted.

Abstract: An inflation valve for inflating containers with non-rigid walls, has a body with a passage and first tubular part with a first opening at one end leading into the passage and a second opening at its opposite end leading into the passage. A cap is removably fitted over the body for closing the first opening to the passage. A first sealing disc, which closes off the second opening to the passage, is adapted to open the second opening when an inflation device is inserted into the second opening to allow gas to be inserted into the container through the second opening. A guide member is located within the first tubular part to support a spring for assisting the first sealing disc in closing off the second opening.

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.
