Patent

CA 2245140

A reusable dunnage bag is provided for placement between or among boxes or packages of diverse products packed or stored for shipment in trailers or containers so as to cushion and protect the products from damage in being transported from one location to another. The bag includes a self closing valve operable to open so as to permit entry of pressurized medium into the bag, but automatically closes when fully inflated. A gun-like device having dual nozzle means is provided for opening the self closing valve for rapid admission of gaseous medium into the bag and for opening the valve to quickly expel the medium therefrom. A discernible difference in noise frequency signals an operator to remove the connection between the gun and the self closing valve when inflation of the bag is complete.
