Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a hanger attachment structure suitable for use in containers, particularly so-called flexible container bags.

BACKGROUND ART As an example of a conventional flexible container bag hanger attachment structure, reinforcing bands are sewn in multiple stages around the body, and hangers are sewn to these reinforcing bands. As another example of the conventional flexible container bag hanger attachment structure, a part of the body is folded into an S-shape by a fold line extending along the axial direction from the top of the body to almost the bottom, and this S-shaped part The base of the handle was inserted, and the S-shaped part and the base of the handle were sewn together.

Problems to be Solved by the Invention However, among the conventional examples described above, the former structure requires a large sewing area and is not only inferior in work efficiency for attaching the hanging hand, but also increases in weight and is expensive. Also, since a reinforcing band is sewn around the body, it is difficult to fold it flat.

On the other hand, in the latter structure, the sewing area can be reduced, but the work of inserting the base of the hanger into the S-shaped portion of the trunk is troublesome, and the efficiency of the hanger attachment operation is poor. In addition, since the S-shaped part is folded along a fold line that extends along the axial direction from the top of the body to almost the bottom, powder, etc. should be placed inside the body below the seam in the S-shaped part. When stored, a load is always applied so that the bag is unfolded to its original state before being folded, and a large load is placed on the lower end of the sewn part, which makes it easy to cut and has poor attachment strength to the hanger.

The present invention can improve the efficiency of the hanging hand installation work. Furthermore, it is an object of the present invention to provide a structure for attaching a hanger to a container, which can reduce weight and cost, improve the attachment strength of the hanger, and further enable easy folding into a flat shape. The purpose is to

Means for Solving the Problems The technical solution of the present invention for solving the above problems is that the edge of the body of the container is folded at multiple points in the circumferential direction, and the edge of the body is used as the bottom; A triangular reinforcing part having one apex in common on the middle part side of the trunk is superimposed in multiple layers in the circumferential direction, and the base of the hanger is superimposed on the outer surface of this superimposed reinforcing part. The respective reinforcing parts and the base of the hanger are sewn together so that the reinforcing parts can be held in the triangular overlapping state.

Therefore, according to the present invention, the base of the hanger is held in such a way that the reinforcing parts are held in a triangular overlapping state together with each of the reinforcing parts formed by overlapping the edges of the body of the container. Since it is sewn to the top, the sewing area can be reduced, and the torso itself can be used for reinforcement, allowing the hanger to be firmly attached. In addition, a triangular reinforcing section with the edge of the body as the base and one apex in common on the middle side of the body is reinforced by superimposing multiple layers in the circumferential direction, so powder particles can be absorbed into the body. When storing a body, etc., there is no load applied to the lower end of the overlapping part that would cause it to expand to its original state before folding.
It is difficult to cut because it covers the entire sewn part. Furthermore, there is no need to provide a reinforcing section in the middle of the body that is inconvenient for folding.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, a first embodiment of the present invention will be described.

FIG. 1 is a perspective view of the entire container to which a hanger is attached, and FIGS. 2A to 2C are perspective views of essential parts for explaining the order of attaching the hanger. As shown in FIG. 1, the container 1 has an input port 4 and a discharge port 5 made of synthetic resin sheet material at the upper and lower edges of the body 3, which is woven into a tubular weave using flat yarn 2 made of synthetic resin such as polypropylene. are connected by means such as sewing. Closing strings 6 and 7 are attached to the input port 4 and the discharge port 5, respectively, by means such as sewing. The bases of a pair of hangers 8 are attached to the upper end edges of the corners of the trunk 3 by sewing.

To explain the mounting structure of the hanger 8, as shown in FIG. The reinforcing portions 9 and 10 are formed by folding and overlapping into a triangular shape, and the triangular reinforcing portions 9 and
10 is sewn along its oblique side with sewing thread 11. As shown in FIG. 2B, each reinforcing part 9, 10 is folded outward along the fold line of the bisector, and each reinforcing part 9, 10 is overlapped, and each reinforcing part 9, 10 is is a reinforcing portion 12, 1 continuous in the circumferential direction
It is polymerized into 3. That is, the reinforcing parts 9, 10, 1 are triangular in the circumferential direction and have the edge of the body 3 as the base and have one apex in common on the middle part side of the body 3.
2 and 13 are polymerized and reinforced. On the outer surface of each reinforcing part 9, 10, as shown in FIG.
The bases of the handles 8 and the respective reinforcing parts 9, 10, 12, 13 are combined into the reinforcing parts 9, 1.
0, 12, and 13 are sewn together with sewing thread 22 so that they can be held in a triangular overlapping state.

The respective reinforcing parts 9, 10, 12, 13 formed by overlapping the end edges of the body part 3 in the circumferential direction in this way
Since the base of the hanger 8, which is overlapped with the comrade and its outer surface, is sewn so that the reinforcing parts 9, 10, 12, and 13 are held in a triangular overlapping state, the efficiency of the installation work can be improved. In addition, the sewing area is reduced, and the torso itself is reinforced,
The hanging hand 8 can be firmly attached. Further, as described above, the triangular reinforcing portions 9, 10, 12, and 13 of multiple layers in the circumferential direction, which have the edge of the body 3 as the base and have one apex in common on the middle part side of the body 3, are superimposed. Since the reinforcing parts 9, 10, 12, 13 are reinforced when powder or the like is stored in the body part 3, the polymerized reinforcing parts 9, 10, 12, 13
Since no load is applied to the lower end of the bag to cause it to unfold before being folded, and the load is applied to the entire sewn part, the sewing thread 22 is difficult to break, and the attachment strength of the hanger 8 is excellent. Since there is no need to provide a reinforcing part in the middle part of the body part 3, it can be easily folded flat.

Next, a second embodiment of the present invention will be described.

Figure 3 is a developed view of the main parts of the torso, Figures 4 A to C
FIG. 2 is a perspective view of a main part for explaining the order of attaching the hanger. Third
As shown in the figure, a triangular reinforcing part 15 is formed at the upper end edge of the corner of the body part 3, with the center line 14 bisecting the triangular reinforcing part 15. 16 and 17, and reinforcing parts 18 and 19 are formed at substantially equal angles to the reinforcing part 15. Then the fourth
As shown in FIG. It is sewn on. The reinforcing parts 15 and 18 are integrally stacked on the reinforcing part 19 as shown in FIG. That is, circumferentially triangular reinforcing parts 18, 15, and 19 having the end edge of the body part 3 as a base and having one apex in common on the middle part side of the body part 3 are overlapped and reinforced. The bases of the hangers 8 are superimposed on the outer surface of the reinforcing part 18, and these hangers 8 and the respective reinforcing parts 18, 15, 19 are connected to the reinforcing parts 18, 1.
5 and 19 are sewn together with sewing thread 22 so that they can be held in a triangular overlapping state.

The other configurations and effects are the same as those of the first embodiment, so their explanation will be omitted.

In addition, in the weaving process of the base fabric constituting the body part 3, the reinforcing parts 9, 10, 12, 13, 15, 18,
19 and the reinforcing portion may be partially woven with polyamide fiber yarn or polyester fiber yarn having excellent tensile strength along the hanging direction following these reinforcing portions to form a reinforcing band portion.

Effects of the invention As described above, according to the invention, the reinforcing parts are formed by superimposing the edge of the body of the container into multiple layers in the circumferential direction, and each of these reinforcing parts and the base of the hanger are The reinforcing parts are sewn so as to be held in a triangular overlapping state. Therefore, it is possible to securely attach the hanger by reducing the sewing area, and since the base of the hanger is overlapped and sewn to the outer surface of the reinforcing portion, the efficiency of attaching the hanger can be improved. Furthermore, since the trunk itself is used for reinforcement, it is possible to reduce weight and cost. In addition, a triangular reinforcing section with the edge of the body as the base and one apex in common on the middle side of the body is reinforced by superimposing multiple layers in the circumferential direction, so powder particles can be absorbed into the body. When a body, etc. is stored, the load that would cause it to expand to the state before folding is not applied to the lower end of the overlapping part, but is applied to the entire sewn part, making it difficult to cut and improving the attachment strength of the hanger. I can do it. Furthermore, since there is no need to use a reinforcing part in the middle part of the body, it can be easily folded flat.
