Description

[Detailed description of the device]

[0001]

[Technical Field of Device]

 The present invention relates to a flexible container, and more particularly, to a flexible container having an outer bag and an inner bag, which prevents the inner bag from slipping off.

[0002]

[Prior art and problems]

 As shown in FIG. 4, the flexible container has an outer bag 1 made of a flexible and durable sheet material, and a hanging string 2 provided on the outer bag 1. It has a structure in which an opening / closing port 3 is formed at the top and bottom. The opening / closing port 3 can be opened / closed by a tightening string 4. When storing powders, resin pellets, etc. that are difficult to absorb foreign matter, absorb moisture, and oxidize in such flexible containers, use a flexible film material such as polyethylene film or woven cloth as shown in Fig. 5. It is also known to provide the manufactured inner bag 5. When such an inner bag 5 is provided, the opening / closing port of the inner bag 5 is integrally connected by the opening / closing port 3 of the outer bag 1 and the tightening string 4.

When the flexible container having the inner bag 5 as described above is used, it is hung on the hoist jig 6 by the hanging cord 2 as shown in FIG. 5, and the bottom of the flexible container is opened and closed. The tightening cord 4 of the mouth 3 is unwound and opened, and the stored powder 8 is dropped or sucked into the hopper 7, for example. At this time, if the stored powder 8 is sufficiently left in the flexible container, the stored powder 8 in the inner bag 5 is smoothly dropped or sucked. However, when the remaining amount of the stored powder becomes small, as shown in FIG. 6, the hanging portion 11 of the outer bag 1 provided with the hanging cord 2 is lifted upward, that is, the central portion of the flexible container is raised. It will be dented.

In such a state, since the inner bag 4 is only attached to the outer bag 1 by the opening / closing opening at the top, both shoulder portions 41, 41 are slightly lowered, and as a result, the inner bag 4 is lowered. The opening / closing port 4 of the outer bag 1 projects from the opening / closing port 3 of the outer bag 1, and the protruding portion 42 closes the discharge port 71 of the hopper 7, which makes it difficult to discharge the powder 8 smoothly. There were some drawbacks.

The present invention has been made in view of the above problems, and an object thereof is to provide a flexible container having a flexible container having an outer bag and an inner bag, in which the inner bag is prevented from slipping off. To do.

[0006]

[Means for solving problems]

 In order to solve the above problems, a flexible container according to the present invention has an outer bag provided with a hanging string and an inner bag housed inside the outer bag, and the outer bag and the inner bag are provided at the top and bottom. In a flexible container that has an opening / closing port and this opening / closing port is integrally connected with a tightening string, the opening / closing port on the side where at least two hanging strings are installed is tightened so as to form a ring. A suspension belt that is tied with a string and that passes through the inside of the ring and extends from the one hanging string to the other hanging string is provided such that at least one is detachable.

Further, the flexible container according to the present invention has an outer bag provided with a hanging string and an inner bag accommodated in the outer bag, and the outer bag and the inner bag have opening and closing ports at the top and bottom. In addition, in the flexible container that has this opening and closing port integrally tied with a tightening string, the opening and closing port on the side where the hanging string for hanging on the hoist jig is provided forms a ring. A suspension belt is detachably attached to at least one of the outer bag through the ring and the hoist jig upper part from the upper part of the outer bag.

Further, the flexible container according to the present invention has an outer bag provided with a hanging string and an inner bag accommodated in the outer bag, and the outer bag and the inner bag have opening and closing ports at the top and bottom. In a flexible container that has the opening and closing port integrally tied with a tightening string, the opening and closing port on the side where the hanging string is provided is a ring-shaped belt provided near the hanging string of the outer bag. It is characterized by being united in.

【Example】

 FIG. 1 shows an example of the flexible container of the present invention. This flexible container has an outer bag 1 made of a flexible and strong sheet material, and the outer bag 1 provided in the outer bag 1. It has an inner bag 5 (see FIG. 4) to be stored in. The outer bag 1 is provided with a hanging string 2, and an opening / closing port 3 is formed at the top and bottom of the outer bag 1, and is tied together with the opening / closing port of the inner bag 5 with a tightening string 4. .

In such a flexible container, the opening / closing opening 3 on the side where the hanging string 2 is provided is tied so as to form the ring 31 by the tightening string 4. Then, the suspension belt 9 passes through the ring 31 from one of the hanging straps 2 and is inserted into the other hanging strap 2. At least one of the suspension belts 9 is free and is detachably attached to the hanging strap 2. After the opening / closing opening 3 is formed in a ring shape, the suspension belt 9 is attached to the formed ring 31. It can be inserted.

Due to such a structure, when the hanging string 2 suspends the hoist jig 6 and the remaining amount of the powder 8 to be stored becomes small, the suspension belt 9 causes the opening / closing 3 to move upward. Since it is supported by the flexible container, no recess is formed at the top of the flexible container. That is, the portion 11 provided with the hanging string 2 is not lifted up, and the outer bag 1 retains its almost original shape. For this reason, the inner bag 5 can also retain its original shape, and there is an effect that deviation does not occur.

FIG. 2 shows a second embodiment of the present invention. In this embodiment, the suspension belt 9 is fixed to the upper portion of the outer bag 1 and the opening and closing formed by the tightening cord 4 in a ring shape. It passes through the ring 31 of the mouth 3, straddles the hoist jig 6, and is detachably fixed to a ring-shaped belt 10 formed near the upper portion of the outer bag 1 where the hanging strap 2 is provided.

Also in this case, when the hanging strap 2 suspends the hoist jig 6, the suspension belt 9 pulls the opening / closing opening 3 upward. Even if the inner bag 5 becomes smaller, the shape of the outer bag 1 does not change, so that the inner bag 5 can retain the same shape. Therefore, the inner bag 5 does not fall off.

FIG. 3 shows a third embodiment of the present invention. In this embodiment, a ring-shaped belt 10 is provided in the vicinity of a portion 11 of the outer bag 1 which is lifted by the hanging strap 2 and is opened and closed. The mouth 3 is tied and fixed to the belt 10. Therefore, when it is hung by the hanging string 2, the opening / closing port 3 is pulled upward by the portion 11 to be lifted, and as a result, the shape of the outer bag 1 is almost maintained. Therefore, the inner bag 5 does not fall off.

[Effect of device]

 As described above, according to the present invention, when the remaining amount of the powder contained in the flexible container becomes low, the opening / closing opening formed at the top of the flexible container is pulled upward. The initial shape of the outer bag is maintained, and as a result, the inner bag can be prevented from slipping off.
