A bulk container of flexible fabric having a substantially rectangular base (53) and four walls (22) with four corners at the junctions (36) of the walls has four interior bridging panels (25) extending between adjacent walls across the corners, the bridging panels (25) each being formed of fabric which is integral with part of said adjacent walls. In one embodiment, the four bridging panels and the four wall centre panels (22) are formed of a single main piece of fabric (20), and the corners are formed by corner pieces (23, 24) attached to the main piece of fabric (20) at the junctions (38) between the bridging panels (25) and the wall centre panels (22). The corner pieces (23, 24) each comprise a folded strip of fabric which forms a lifting device (45). Holes (10a) are cut through the bridging panels by laying the main piece of fabric (20) in doubled condition and cutting two layers in one operation. The container has a pyramid shaped top cover (46) with a central filing chute (47), and an outlet chute (55). In other embodiments, each bridging panel forms part of an integral corner unit and the shell of the bag is formed by joining four corner units and four wall centre panels. Other forms of lifting device are also described. <IMAGE> <IMAGE> |
