Problems solved by technology

[0002] Leakage often occurs when flexible container bags are used to hold powdery or fine granular materials. The general solution is to add a plastic film inner bag to the container bag, and the inner bag can solve the leak-proof problem, but on the one hand This increases the cost, and on the other hand, increases the difficulty of loading and unloading. As a result, there is a method of coating the woven fabric of the container bag body, the upper cover and the lower bottom, and then making it into a bag. However, due to the limitation of the sewing process, the seams are still Leakage will occur, mainly because sewing causes pinholes in the woven fabric at the seams, and leakage from the pinholes. If this problem is solved, you can directly use the film-coated woven fabric to produce container bags to directly hold powder or small Granular matter without leakage

Embodiment 1

[0033] Figure 1 to Figure 10 Figure 1 of this example is given. see Figure 1 ~ Figure 3 , the flexible bag body 1 adopts circular weaving tubular cloth to form. The upper cover 2 and the lower bottom 3 are located on and below the bag body and are sewed into one body with the bag body. One end of the upper inlet 4 and the lower outlet 5 is respectively sewed with the loam cake, the lower bottom and the body of the bag as a whole and there is a reinforcement 13 thereon. The upper entrance and the lower exit are respectively connected with fork reinforcement 7 by sewing. Each sewing seam is made with Figure 4 ~ Figure 6 The outsourcing method or the internal blocking method as shown in Figure 7 and Figure 8 or the Figure 9 , Figure 10 The interlining method shown uses leak-proof parts to prevent leakage.

[0034] Figure 4 ~ Figure 6 It is a schematic diagram of leakage prevention by outsourcing. That is, at the sewing seam of the woven cloth, the sewing edge is wr...

Embodiment 2

[0038] Figure 11 ~ Figure 13 Figure 2 of Embodiment 2 of the present invention is given. The present embodiment 2 is basically the same as that of embodiment 1. The difference is that the flexible bag body 1 is made into flat cloth by a flat loom and then drenched, and then stitched together to form a cylindrical bag body.
