Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a grain storage bag used for storing grains such as rice.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, a grain storage bag in which the opening of the bag is closed with a fastener or the like after the stored items are stored is described in Japanese Utility Model Publication No. 59-118745. In this grain storage bag, insertion holes for support are provided at both ends of the opening, and the opening is closed by a fastener or the like provided between the insertion holes.

On the other hand, in a bag for storing grains such as rice, there is a grain storage bag in which an opening of the bag is manually closed after storing items such as rice. In this grain storage bag, the peripheral edge of the opening is folded and the string provided in the opening is tied and closed.

[0004]

[Problems to be solved by the device]

 However, since the grain storage bag using fasteners etc. has the insertion holes for support at both ends of the opening, the grain storage bag has the both ends of the opening expanded. Is. However, the bag for storing grains such as rice is not only graded for the rice itself, but the appearance after storing is also an important factor. Therefore, the storage bag in which both ends of the opening are wide is not suitable for storing grains such as rice because the appearance after storage is not good.

On the other hand, a grain storage bag of a type in which a string body provided in the opening is tied and closed is used because the opening portion is folded in, so that it can be closed in a good appearance to some extent, but it is a manual operation. As a result, the shape is not constant and the appearance changes depending on the skill level of the worker.

Therefore, the present invention has been devised to solve the above-mentioned problems, and in a grain storage bag of a type in which a cord body provided at the opening is tied and closed, the appearance of the opening is improved. It is an object of the present invention to provide a grain storage bag which can be arranged and whose opening can be closed in a certain shape regardless of the skill of a worker.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the first means is a grain storage bag in which a pair of cords S provided in the opening P1 are tied together and closed, and a bag P at the end provided with the cord S of the opening P1. The triangular shape-retaining plate 1 is provided inside.

The shape-maintaining plate 1 of the second means has an isosceles triangular shape which is provided along the folding side edge P2 extending from the opening P1 and has a diverging shape, and the folding side edge P2. In each section, each shape-maintaining plate 1 is provided with a bent portion 2 that is folded in two.

Further, in the third means, the bent portion 2 of the shape holding plate 1 is separated along the folding side edge P2 as means for solving the problem.

[0010]

[Action]

 According to the first means of the present invention, when the pair of cords S provided in the opening P1 are tied together, the triangular shape retaining plate 1 is folded inside the opening P1 of the bag P to retain the shape. The shape of the plate 1 makes the shape of the closed mouth constant.

By the second means, the triangular shape retaining plate 1 is folded in two along the folding side edge P2 extending from the opening P1 when the bag body P is flattened.

The third means is that the shape-holding plate 1 that is folded in two is folded without resistance when folding the folding side edge P2.

[0013]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

The bag body P of the invention has a pair of cords S provided in the opening P1, and the cords S are tied and closed. Then, the triangular shape retaining plate 1 is provided on the inner side of the bag P at the end of the opening P1 where the cord S is provided.

The shape-retaining plate 1 has an isosceles triangular shape which is provided along the folding side edge P2 extending from the opening P1 and has a diverging shape. The shape retaining plate P2 holds each shape. Each plate 1 is provided with a bent portion 2 that is folded in two. The shape retaining plate 1 uses, for example, cardboard or a plastic material. It is also possible to embed it inside the material forming the bag P, as well as adhering to the inner surface of the bag P.

The bent portion 2 of the shape retaining plate 1 shown in the figure is formed so as to be foldable by being separated along the folding side edge P2. Further, the bent portion 2 can be made foldable without being separated, for example, by forming the bent portion 2 thinner than other portions of the shape retaining plate 1. Further, the shape retaining plate 1 is detachably provided, and the shape retaining plate 1 is attached to the opening of the same type of bag body to which the shape retaining plate 1 is not attached.

In use, the opening P1 of the bag P is folded from the end to the portion of the string S, and then the strings S are tied together so that the closed opening P1 has the shape of the shape retaining plate 1. It is arranged into a shape (see FIG. 2).

[0018]

[Effect of device]

 The present invention achieves the original purpose by being configured as described above.

That is, according to the first aspect, by tying the pair of cords S provided in the opening P1 together, the appearance of the opening P1 can be properly adjusted. Moreover, since the shape retaining plate 1 provided inside the opening P1 adjusts the shape, it is possible to close the opening P1 to a constant shape regardless of the skill of the operator.

Further, according to the second aspect, even when the unused bag body P is folded along the folding side edge P2 in a flat state, the shape-retaining plate 1 is respectively in the folding side edge P2 portion. Since it is folded in two, it does not interfere with non-use.

Further, in the third aspect, the bent portion 2 of the shape retaining plate 1 does not have to have a crease of the shape retaining plate 1 itself, and moreover, can be folded without resistance even when folding the folding side edge P2. Therefore, the bag P can be prevented from being damaged by the shape retaining plate 1.

As described above, according to the present invention, in a grain storage bag of a type in which the string body provided in the opening is tied and closed, the appearance of the opening can be properly arranged, regardless of the skill of the operator. It has various practically useful effects such as the ability to close the opening into a fixed shape.
