ABSTRACT:
A foldable bag for transporting dry granular powders has a flexible and collapsible skin top, sides and a base with the base a base incorporating a fluidizing port. To transport material the bag is supported to the frame or structure of a container and filled with any dry granular powder. The filling is performed through an orifice in the top portion of the bag. At a destination the contents of the bag are fluidized by providing aeration of the contents through the base of the bag. Once fluidized the contents of the bag are then emptied under gravity or vacuum through outlet ports in the base of the bag. The fluidizing is accomplished a series of channels in the base of the bag with holes for the release of air and with an aeration cloth generally covering these holes. The base of the bag incorporating the fluidizing can be detached from the rest of the bag enabling appropriate recovery or repair of parts of the bag. The bag is provided with ties or the like to support the bag to the frame or structure of a container when being used to transport dry granular powders. The bag can be used with a variety of standard containers. When empty the bag can be folded, including the base portion, for storage or return for re-loading while the container is free for other uses.
