Lifting rope type cylindrical shipping sack

Abstract

A sling-type cylindrical container bag, which includes a cylindrical bag body sewn with a top cover and a bottom bottom, which are sewn with polymer material woven cloth, the top cover of the bag body In the middle of the bottom and the lower bottom, there are respectively a feeding port and a feeding port. On the circumferential wall of the bag body, four slings are sewn vertically and symmetrically downwards, and the upper ends are folded into rings, and the slings are folded all the way down to the bottom edge. To the bottom surface, in the middle position and the enclosing sewing edge around the discharge port, they are sewn together after overlapping; at least two horizontal bands are sewn up and down on the cylindrical wall surface of the bag body, wherein the last band and the The slings are sewn together crosswise; a sling is arranged between two slings on the bag body, and the lengths of the two slings are the same; A reinforcing block is placed at the cross seam; it has the characteristics of simple structure, convenient manufacture and use, good safety, small space occupation, and improved shipping efficiency.

Description

technical field [0001] The invention relates to a sling-type cylindrical container bag made of woven cloth made of polymer raw materials, which belongs to the technical field of container containers for bulk materials. Background technique [0002] In the prior art, conventional bulk materials need to be transported in container bags, but conventional container bags are sewn from cloth, but container bags made of such cloth lack fastness and can only be made into small Larger container bags are made by other methods, so the shipping efficiency of bulk materials is low, the service life is short, and it is easy to be damaged. [0003] Although the present patent bulletin discloses a container bag made of woven cloth made of polymer raw materials, which solves the collection and transportation of large-capacity bulk materials, and has high fastness and greatly increases the service life. There are defects such as inconvenient and low efficiency for collecting and transporting...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, conventional bulk materials need to be transported in container bags, but the conventional container bags are made of cloth, but the container bags made of this cloth lack fastness and can only be made into small Large-capacity container bags are made by other methods, so the shipping efficiency of bulk materials is low, the service life is short, and it is easy to be damaged

[0003] Although the present patent bulletin discloses that there is a container bag made of woven cloth made of polymer raw materials, which solves the collection and transportation of large-capacity bulk materials, and has high fastness and greatly increases the service life, but because of the unreasonable design of the production structure, it is still There are defects such as inconvenience and low efficiency in collecting and transporting bulk materials
