Description

[Detailed Description of the Invention] The present invention relates to an improvement of a grain bag for storing grains such as rice and soybeans.

Since grain bags containing grain are stacked in large quantities in warehouses, pressure is applied to the lower bags, and if the bag is simply tied with a string, the bag opening may open, or if it is thrown during transportation, the impact may cause the bag opening to open. There is a risk of it opening.

Therefore, the object of the present invention is to obtain a bag for grains whose opening can be easily and reliably closed.

To explain based on the embodiment shown in the drawings, in FIG. 1, two valve plates 2 and 3 are stacked on one side of the inner surface of the bag opening 1, inside and outside, and their lower sides are sewn, and the left and right sides of the valve plates and the bag are sewn together. A space M is formed between the two ends of the mouth.

The valve plates 2 and 3 may be made of the same material as the grain bag or a different material, such as cloth made of synthetic resin strips woven vertically and horizontally, kraft paper, or linen cloth.

When grains are packed into the bag body A as shown in Figure 2, the inner valve plate 2 is folded inward to cover the grains, and a string such as straw rope is tied to the upper end of the outer valve plate 3. Tie a book or multiple books together and roll them inward.

After the bag has been rolled up to the opening as shown in Figure 3, the bag opening 1 is also rolled up as shown in Figure 4, and the left and right sides of the bag are folded inward as shown in Figure 5 and the string 4 is tied.

In this way, the inner valve plate 2 covers the grains, and the outer valve plate 3 has an appropriate string wrapped around it together with the bag opening 1, and there is a space between both ends of the bag opening and the valve plates 2 and 3. Since it has M, even if the bag opening is rolled up, both sides will not become thick, so it can be easily folded inward as shown in Figure 5, and the center of the bag opening is thick and tight, so it can be stacked high or dropped from a high place. There is no risk of the bag opening opening and the grains spilling out.

In this way, according to the present invention, the inner valve plate 2 is connected to the bag body A.
Since it covers the surface of the grains stored inside, it not only prevents the grains from flying out from the bag opening, but also because the outer valve plate 3 wraps around the string 4 as a core, so that the string 4 is well-ventilated. Since it is integrally connected to the bag body A via the plate 3 and the bag mouth does not need to be rolled up so much, the storage capacity of the bag body A can be increased.Moreover, both sides of the rolled bag mouth can be easily folded inward due to the space M. This produces the effect that it is possible to
