摘要： block-shaped container (1) for bulk material, comprising a flexible material and having stabilizing means (5) for preventing the bulging of its side walls (12, 13) under the influence of said material bulk. Said stabilizing means (5) are in the form of flexible material strips (7) fixed by one of their sides to one of the side walls of the container (12, 13) and by the other side to a thin core walls (16) whose cross-section is closed in a plane at right angles to side walls (12, 13). The core (6) is preferably a ring or pipe of flexible material on the outside which extend the strips (7) of flexible material. The filling opening is situated directly above the core (6), so that filling of the container (1), the bulk material initially falls within the core (6) exerts pressure on the flexible material of said core (6) facing outwards in a radial direction and tends to form a cylindrical shape. Stable core (6) having taken said stretched shape by means of flexible strips (7) prevents the bulge of the container walls.
