Abstract (en)
The present invention relates to a flexible container for transport and storage of bulk material and a method for its manufacture. The container shall endure the strains it is exposed to during a drop test in the bursting zone having a radial bursting effect. The container (1) consists of a hose-formed piece of material which upper part is joined with its central part (12) by joints (8) which form an angle 0 DEG <x<90 DEG , preferably 30 DEG <x<60 DEG with the longitudinal direction of the material. The joints (8) can be in the form of a V or W and the extreme point (B) if preferably above the bursting zone (9). The container (1) can be made from a flattened hose-formed piece of material which is cut in two symmetrical parts (1) along a line cut a, a min , b min , b where the lines a, a min and b min , b form an angle 0 DEG <x<90 DEG with the longitudinal axis of the material and the line (a min -b min ) >/= 0 is vertical in the middle of the piece of material (1) on both sides of the folded line (1). The upper part of the piece of material (1) is folded over the line (2) and joined with the part (12) along cut lines for forming lifting loops (5). The container combines the requirements to high tensile strength and high resistance to strain in the bursting zone (9).
