ABSTRACT:
A flexible container for transporting and storing bulk goods, preferably arranged so as to be liftable by its upper end, is constructed from a tubular blank so as to include a shell, a bottom and a filling aperture, pleats being formed in the shell and having lower parts which are folded so as to be coplanar with the container bottom. The free, lower margin of the tubular container blank is closed by a bottom seam located substantially in the central region of the container bottom and the upper plane of each pleat is folded into the plane of the container bottom and affixed to the lower plane of the respective pleat by a connecting seam. On each side of the bottom seam, there is at least one supporting seam substantially parallel to the bottom seam. The distance of each supporting seam is advantageously in the range of about 1/3 to 1/4 of the half-length of the connecting seam.
