The container has a usable space formed by top, bottom, and side walls that are constructed from a plurality of fabric sheets. The portions of the fabric sheets that enclose the usable space are welded together to provide a stitchless usable space. Upper portions of the sidewalls extend upward beyond the usable space to form a hem. Lift loops that enable the large container to be lifted by mechanical means are sewn onto the hem. Thus, the usable space remains stitchless, i.e., without stitch holes, yet the lift loops are stitched to the hem. ## Claims ### Claim at position 1 1-15. (canceled) ### Claim 16 A flexible large container for receiving bulk material, the flexible large container comprising: a plurality of fabric sheets that are assembled together to form a stitchless usable space having four sidewalls, a floor, and a cover; a hem that is formed by two or more of the plurality of fabric sheets, an upper end of these two or more fabric sheets extending upward beyond the cover, such that the hem is above the usable space; and a plurality of lift loops that are attached to the hem. ### Claim 17 (depends on 16) The flexible large container of claim 16, further comprising: a belt that extends along the hem; wherein the plurality lift loops are formed by the belt, which is lifted away from the hem into an omega shape at each location of a lift loop, and wherein the belt, where not formed in the omega shape, is stitched to the hem. ### Claim 18 (depends on 15) The flexible large container of claim 15, further comprising: a belt that is stitched to the hem; wherein the plurality of lift loops are attached as separate elements to the belt. ### Claim 19 (depends on 18) The flexible large container of claim 18, wherein each loop of the plurality of loops has a lower end that is U-shaped and therefore has two layers, wherein the belt is sandwiched between the two layers, and wherein stitching to fasten the lower end of the loop to the belt is stitched through the two layers and the belt. ### Claim 20 (depends on 16) The flexible large container of claim 16, wherein the fabric sheets contain polyethylene. ### Claim 21 (depends on 20) The flexible large container of claim 20, wherein the fabric sheets that form the usable space are woven with weave fibers that are woven in two directions that cross each other and wherein at least the weave fibers of one direction contain polyethylene. ### Claim 22 (depends on 21) The flexible large container of claim 21, wherein the weave fibers are synthetic tapes. ### Claim 23 (depends on 21) The flexible large container of claim 21, wherein the weave fibers are synthetic filaments. ### Claim 24 (depends on 20) The flexible large container of claim 20, wherein the polyethylene is a high density polyethylene. ### Claim 25 (depends on 20) The flexible large container of claim 20, wherein at least one of the fabric sheets has a liner that contains polyethylene and is laminated to a side of the at least one fabric sheet that faces in toward the usable space. ### Claim 26 (depends on 16) The flexible large container of claim 16, further comprising a corner support, wherein any two adjacent sidewalls form a corner area and wherein the corner support is attached to each of the two adjacent sidewalls, so as to extend diagonally across the corner area along a vertical section of the corner area, and wherein the corner support has openings that allow the bulk material to flow into the corner area. ### Claim 27 (depends on 16) The flexible large container of claim 16, wherein the cover is joined to the sidewalls with a welded seam and the hem extends upward beyond the welded seam. ### Claim 28 (depends on 16) The flexible large container of claim 16, further comprising a fill tube that is provided in the cover, wherein the cover is constructed of a certain type of fabric and the fill tube is constructed as a separate element of the certain type of fabric, and wherein the fill tube and the cover are attached to each by means of a welded seam. ### Claim 29 (depends on 16) The flexible large container of claim 16, further comprising a discharge tube that is provided in the floor, wherein the floor is constructed of a certain type of fabric and the discharge tube is constructed as a separate element of the certain type of fabric, and wherein the discharge tube and the floor are attached to each other by means of a welded seam. ### Claim 30 (depends on 16) The flexible large container of claim 16, wherein the plurality of the fabric sheets that surround the usable space have seam edges and wherein the seam edges of each of two adjacent sheets of the plurality of fabric sheets are overlapped and welded together to form a welded seam. ### Claim 31 (depends on 30) The flexible large container of claim 30, wherein an intermediate layer containing polyethylene is placed between the seam edges of the two adjacent sheets and is incorporated into the welded seam. ### Claim 32 (depends on 16) The flexible large container of claim 16, wherein an area of fabric where each of the plurality of lift loops is attached to the hem is reinforced.
