| 摘要 |
The invention concerns a flexible container (10) for transporting and storing bulk goods (a so-called largesize bag) comprising a shell bottom (12) filling aperture (13) and arranged to be liftable by its upper end, and in the shell (11G) of which have been formed pleats (21), the lower parts of these pleats being folded to be complanar with the bottom. With a view to strengthening the vulnerable region of the bottom and to enabling the manufacturing of the container to be readily automated, the invention teaches closing of the tubular container blank by a seam (20), known in the art, located substantially in the central area of the bottom and folding down the upper plane of the plate into the plane of the bottom and its affixing to the lower plane by a seam. The opposing planes of the pleats may be interconnected by a seam in their marginal area, and they may also be affixed to each other substantially centrally by additional seams, which may be substantially parallel with the seam connecting the lower plane of the pleat to the bottom.
