A fabric bag for handling dry bulk cargo is disclosed, of the type in which four sides, a top and bottom are assembled to approximate the shape of a right quadrilateral prism. A continuous fabric liner is provided inside the bag and four corner baffles are sewn into the liner so as to offset a portion of the lateral outward loading due to the dry bulk cargo and thereby reduce bulging of the bag sides. Since the baffles are stitched only to the liner, and not to the outer sides of the bags, this leaves the central portions of the bag sides free of stitching and available for improved display of graphic or textual material.

An improved bag for handling dry bulk cargo, said bag comprising: a body comprising four sides and a bottom and approximating, when filled with cargo, the shape of a right quadrilateral prism, with said four sides, in cross-sectional plan view, forming a quadrilateral shape with four corners; lifting means attached to said body and adapted to cooperate with equipment for handling said bag; a woven fabric liner disposed inside said body adjacent the inside surfaces of said four sides, said liner being joined only along its upper periphery to said four sides of said bag body, said liner being open topped and open bottomed and terminating short of the bottom of said bag; four generally vertical baffles disposed inside said liner and joined to said liner, but not to said sides of said bag body, along substantially the entire length of the vertical edges of said baffles, said baffles and said liner forming, in cross-sectional plan view, a generally quadrilateral shape having four generally triangular shapes therein, with one such triangular shape having its apex in each of said four corners of the bag body, said baffles and said liner being adapted to offset at least a portion of the lateral cargo loading forces on said four sides of said body to thereby reduce bulging of said four sides, whereby the generally prismatic shape of the filled bag is improved.
