ABSTRACT:
A particulate solids transport bag with a gas assist unloading feature. The bag is one having an enclosing flexible side wall, or walls, flexible bottom wall provided with an opening, preferably a spout, and a gas distributor. The gas distributor is of tubular shape formed by a flexible material located atop or upon, around or surrounding said bottom wall opening, or spout, and contains a gas permeable upper face, gas impervious lower face and gas inlet into the tubular space. Gas, particularly air, is injected via the inlet into the tubular opening and passed through the gas permeable upper face of the flexible material to aerate and render the solids flowable for discharge through the opening, or spout, of the bottom wall.
