Abstract:

A bulk material transport bag has a plurality of sidewalls, a lower end wall, and an upper wall, defining a bulk material space therewithin. The surrounding sidewalls are formed by a panel of fabric, positioned at each corner of the bag, the panel of fabric formed into a right triangle, so that the first and second legs of the triangle form the outer wall of the bag at each corner, and the third leg (or hypotenuse) of the triangle forms the internal baffle wall of the bag. Each corner triangle is stitched to a flat panel of fabric, defining the remaining central portion of each sidewall, so that when the eight portions of fabric are joined, there is defined the enclosed wall of the bag, together with the baffles formed in the interior of the bag. The bag includes a plurality of rectangular or triangular shaped openings in each of the baffle walls for allowing bulk material to flow therethrough in order to completely fill the bag. The baffle walls include fabric portions between each opening to define a means for maintaining the baffle walls intact under the weight of the bulk material.
