SOLUTION: The inner bag 2 made of polyethylene formed longer than the outer bag 1 made of polypropylene and provided with a fastener on a bag port is inserted and elastic bodies 5 molded by rubber or the like are provided on both end parts of a rod body for holding both front and back surfaces on the lower side of the supply port of the inner bag 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cereal storage bag for storing cereals such as rice and beans.

[0002]

2. Description of the Related Art A rod-shaped means is convenient as a means for sealing the supply port side of a bag for storing grains.

[0003]

However, bags containing grains are not stored in one place, but are moved to a cool place after bagging, for example. It may hit the outer bag and break through.

[0004]

SUMMARY OF THE INVENTION The present invention provides a grain storage bag for preventing the outer bag from being torn, and employs the following technical means. That is, the inner bag 2 having a vertical width longer than that of the outer bag 1 is inserted into the outer bag 1, and both ends of the rod body 4 that closes the supply port 3 side of the inner bag 2 with both front and rear surfaces interposed therebetween. Is a cereal storage bag provided in the elastic body 5.

[0005]

When the inner bag 2 is inserted into the outer bag 1, the inner bag 2
The supply port 3 comes out above the outer bag 1 because it is longer. Then, cereals are supplied from the supply port 3, and the bar 5 closes the supply port side of the inner bag 2 from both front and rear sides. Next, the upper part of the inner bag 2 is put in the outer bag and stored at a predetermined place.

[0006]

[Effect] The supply port side of the inner bag 2 is connected to the elastic members 6 at both ends of the rod 5.
When transporting a cereal storage bag containing cereals, the bar 5 can be prevented from being torn even if the rod 5 hits the outer bag 1.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. First, the structure will be described. The cereal storage bag A has an outer bag 1 and an inner bag 2, and the outer bag 1 is a bag made of polypropylene (PP).
The lower portion of the tubular material is folded back and forth side by side multiple times to form a sealed bottom portion 6, the upper portion is folded back multiple times inside and side sewn to form a bag mouth 7, and an opening / closing tool ( In the embodiment, the fastener 8 is integrally attached. Reference numeral 9 denotes a handle sewn in a U-shape on the bottom 7 of the outer bag 1 and the front and rear surfaces of the top.

The inner bag 2 is a bag made of polyethylene (PE), and the width L of the supply port 3 provided at the upper end of the cylindrical material is formed smaller than the width 1 of the storage portion 10. The periphery except the opening 3 is sealed by heating with a predetermined width b (5 to 7 mm in the embodiment). The inner surface and / or outer surface of the inner bag 2 is subjected to an oxygen barrier process for preventing oxygen from permeating. A thick portion 11 having a predetermined width is formed in the vertical direction on the outer surface of the inner bag 2 below the supply port 3.

The rod body 4 is composed of a rod piece 13 having a long convex portion 12 having a hollow portion 12a in the lateral direction inside and a rod piece 15 having a concave portion 14 into which the convex portion 12 fits.
The bar pieces 13 and 15 are longer than the width of the inner bag 2 on the supply port side and shorter than the width of the storage portion 10. The rod pieces 13 and 15 are integrally formed of a synthetic resin material and have flexibility. The elastic body 5 has a rod piece 13,
Recesses 16 fitted into both ends of the bar 4 in which
And when they are inserted into the rod 4, they are almost in close contact with each other.

The thick portion 11 has an upper and lower width A approximately twice as large as the width a of the rod 4, and the thick portion 11 may be integrally formed. As described above, a synthetic resin film of another color may be bonded. The thickness portion 11 may be one, but a plurality of thick portions 11 may be provided in the vertical direction. FIG. 10 shows another embodiment of the inner bag 2, which has a thick portion 11.
On the lower inner surface, a convex portion 17 that is long in the lateral direction is provided on one side,
On the other hand, a first opening / closing member 19 having a concave portion 18 fitted into the convex portion 17 is provided integrally. In this configuration, the convex 1
Since the inner bag 2 is closed by fitting the 7 into the concave portion 18, it is easy for the rod body 4 to close the thick portion 11 of the inner bag 2. Further, when the closing by the first opening / closing member 19 is sufficient, the bar 4 does not need to be used, so that the closing operation of the inner bag 2 is simplified.

Next, the operation will be described. First, the inner bag 2 is placed in the outer bag 1 with the supply port 3 facing upward, and a predetermined amount (for example, 30 kg) of cereals (brown rice in the embodiment) is supplied from the supply port 3. Then, an oxygen absorber is placed on the brown rice, and the rod pieces 13 and 15 of the rod 4 are positioned in front of and behind the thick portion 11 of the inner bag 2. The portion 12 is inserted into the concave portion 14 of the bar piece 15 and the thick portion 11 is sandwiched. Then, the elastic members 5 are inserted into both ends of the rod 4.

At this time, since the thick portion 11 is provided at least twice as large as the vertical width of the rod 4, the positioning of the rod pieces 13 and 15 becomes easy, and the position of the rod 13 is changed in the vertical direction. Is not held more than once, so that the sealing effect can be enhanced. Next, the upper part of the inner bag 2 is folded and put into the outer bag, and the outer bag 1 is closed by operating the opening / closing tool 8. The operator may grasp the handles 9 provided at the upper and lower ends of the outer bag 1 and transport it to the storage location. Brown rice is stored in the inner bag that has been deoxidized with a deoxidizer, so that it is possible to prevent deterioration in taste.
