DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag used for storing cereals such as raw rice harvested by a combine (shearing-type threshing machine) from an air duct, and more particularly to a bag capable of self-supporting. It's about the improvement of what we've done.

[0002]

2. Description of the Related Art Conventionally, in storing grains such as raw rice, a grain storage bag has been used in which elastic bars that can be elastically bent are vertically arranged at three or more locations on the side of the bag. (For example, see Japanese Utility Model Registration No. 254932).
When cereals are put into this cereal storage bag from the air duct, the central portion of the bag bulges outward due to its weight. At this time, three or more elastic bars disposed on the side surfaces of the bag are used. At the same time that the bag becomes independent and becomes a support, its open state is maintained. An elastic mouthpiece that can be elastically bent is inserted into the bag along its edge, and the elasticity causes the upper edge of the bag to open outward and the opening is always in a fully open state. So that it can be maintained.

[0003]

In the grain storage bag according to the above-mentioned utility model, holding bands or retaining rings are sewn at a plurality of locations on the edge of the bag, and the elastic mouthpieces are attached to each of them. Unless inserted, the opening cannot always be kept fully open. On the other hand, since the elastic opening rod are those which do not can fold folding <br/> remain attached to the bag mouth, can not be folded so that the bag mouth becomes small while still inserted it, in which case the The elastic rod must be removed. However, this kind of cereal storage bag is 500-1
Since it is made large enough to accommodate about 000 kg and has a very large diameter, it is very difficult to insert an elastic rod into this lip or to remove it from this lip. It is troublesome. The present invention is designed to save such troubles.

[0004]

In the bag of the present invention the means for solving problems], available Der folded while attached to the mouth portion 1a
The mouth 3 is attached so that the mouth 1a of the bag 1 can be kept open when the bag 1 is opened . This mouthpiece 3 is attached
When the bag 1 is folded so that the bag mouth becomes smaller, the mouthpiece 3 is attached to the mouth 1a of the bag 1.
This can be a fold over and over again folded to Ketama. As a result, even if the bag is large, the bag mouth including this mouthpiece 3 can be folded small as shown in FIG. Maintaining Conversely, while expanding the bag 1 folded to the bag mouth is small, the expanded mouth rod 3 that many layers folded folded into a predetermined shape, immediately fully opened mouth edges of the bag 1 can do. Note that the mouthpiece 3 can be expanded to an arbitrary shape such as a circle or a square to maintain the shape.

The mouthpiece 3 which can be folded while being attached to the mouth 1a of the bag 1 may be fixed directly along the edge of the bag 1 by using, for example, a thread for sewing the bag. Further, a band-shaped patch is sewn on the inner surface or outer surface of the bag 1 in the horizontal direction, and folded into the loop-shaped insertion portion formed at that portion.
A collapsible mouthpiece 3 may be inserted. Further, the edge of the bag 1 is folded inward or outward, and the entire edge is sewn to the bag body, and the collapsible mouthpiece 3 is inserted into a loop-shaped insertion portion formed in that portion. Is also good. When the collapsible mouthpiece 3 is inserted into the loop-shaped insertion portion, not only does the mouthpiece 3 not come off, but it is not directly visible, so the appearance is good. At three or more places on the side surface of the bag 1, elastic bars 2, 2 which can be elastically bent are arranged in the vertical direction.

The mouth rod 3 can be replaced by a foldable rod waste. The rod-shaped waste should be provided free of charge because it is to be disposed of. Therefore, the bag can be provided at that low cost. Further, since the rod-shaped waste is foldable, there is no problem even when the bag 1 is folded such that the bag mouth is small as shown in FIG. Folding
Examples of the rod-like waste that can be seen include, for example, rod-like waste made of electric wire waste, metal, synthetic resin, or a composite material thereof. Although the rod-shaped waste for the mouthpiece 3 may have a circular cross section, it is preferable to use a flat band-like waste. This is because it is stiffer and more suitable for the mouthpiece of the grain storage bag.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The most preferred embodiments of the present invention will be described in detail with reference to the drawings. The grain storage bag shown in the drawing is a large-sized one capable of storing about 500/1000 kg of raw rice, and is sewn in a rectangular parallelepiped shape using a synthetic resin cloth which is relatively stiff and somewhat rough. . At four corners of the rectangular parallelepiped bag 1, elastic bars 2, 2 that can be elastically bent in the height direction of the bag 1 are vertically arranged (see FIGS. 1 and 4). In the case shown in the drawings, band-shaped patches 4 and 4 are sewn to the four corners of the rectangular parallelepiped bag 1 in the vertical direction, respectively, and elastic portions are attached to the insertion portions 1b and 1b formed at the portions. All the rods 2 are inserted. In this way, not only can the elastic bar 2 not come off, but it can be made invisible. An elastic rod member 2 that can be elastically bent;
Examples of the rod 2 include a rod-shaped rod made of reinforced plastic, glass fiber, or the like. The number of the elastic rods 2 to be inserted into the respective insertion portions 1b, 1b may be one, or a plurality of thinner members (for example, two) may be inserted.

[0008] At the mouth 1a of the bag 1 ,
A foldable mouthpiece 3 is attached. In FIG. 1, band-shaped patches 5, 5 are sewn in the horizontal direction on the inner peripheral surface of the rim of the rectangular parallelepiped bag 1, respectively, and inserted into the horizontal loop-shaped insertion portion 1 c formed in that portion. The case where the foldable mouthpiece 3 is inserted is illustrated. This way,
Not only does the mouthpiece 3 not come off, but it also looks good because it cannot be seen directly. Since this mouth rod 3 is foldable while mounting can be folded over and over again folding this mouth rod 3 upon folding the bag 1 so that the bag mouth is reduced while attached to the mouth portion 1a of the bag 1 . As a result, even if the bag 1 is large, the bag mouth including this mouthpiece 3 can be folded small as shown in FIG. Conversely, while expanding the bag 1 folded to the bag mouth is small, the expanded mouth rod 3 that many layers folded folded into a predetermined shape, immediately original fully open the mouth edges of the bag 1 Can be maintained. In this case, the mouthpiece 3 is the bag 1
The shape is generally expanded to a square shape according to the shape of the bag 1, but may be maintained in an arbitrary shape different from the shape of the bag 1. In addition, if the mouthpiece 3 is not detached, the mouthpiece is not lost as compared with the type in which the mouthpiece is separated from the bag after the end of the season and stored, and a new mouthpiece is reused after the loss. The labor and cost of purchasing can be saved.

The mouth rod 3 can be replaced by a foldable rod waste. The rod-shaped waste should be provided free of charge because it is to be disposed of. Therefore, the bag can be provided at that low cost. Further, since the rod-like waste is foldable , there is no problem in folding the bag 1 so that the bag mouth becomes small. Examples of the foldable rod-shaped waste include electric wire waste and rod-shaped waste made of metal, synthetic resin, or a composite material thereof. The electric wire waste is particularly excellent in folding performance as compared with other rod-shaped wastes, and can be easily restored, so that it is most suitable for a mouthpiece of a self-supporting grain storage bag. The rod-shaped waste for the mouthpiece 3 shown in FIG. 1 is a flat band. It is stiffer and is more suitable for the mouth of a grain storage bag. However, needless to say, one having a circular cross section may be used.

The grain storage bag shown in FIG. 1 has a four-peripheral edge of the dough 1d covering the upper end opening of the bag 1 sewn to the four peripheries of the mouth 1a of the bag 1 and extended from a combine (not shown). When connected to the tip of the duct A, it is a bottomed one that can be formed into a substantially inverted funnel shape. The vicinity of the center of the cloth 1d is opened so that the tip of the air duct A can be inserted, and the portion can be fixed to the air duct A with a rope 6 or the like. Grains such as raw rice harvested by a combine (not shown) can be stored in the bag 1 shown in FIG.

In the grain storage bag shown in FIG. 3, a cut is made on a diagonal line of the dough 1e covering the upper end opening of the bag 1,
It has a bottom with fasteners 7, 7 attached to its parts. By sliding each of the fasteners 7, 7, the tip end of the air duct A extending from the combine (not shown) can be inserted therein as in the case shown in FIG. In the same manner as in the above case, it can be attached to the air duct A with a rope or the like and fixed thereto. It is preferable that the cloth 1e be substantially inverted funnel-shaped when connected to the tip of the air duct A, similarly to the cloth 1d shown in FIG. Grains such as raw rice harvested by a combine (not shown) are passed through the air duct A in the bag 1 shown in FIG.
Can be stored.

In the grain storage bag shown in FIG.
Mouth cloths 1f, 1f are sewn to the four circumferences of the mouth 1a, respectively, and hanging ropes 8 are inserted into horizontal insertion portions 1g, 1g formed in the respective mouth cloths 1f, 1f. Also in the grain storage bag shown in FIG. 3, similarly to the case shown in FIG. 1, mouth cloths 1 f and 1 f are sewn around the periphery of the mouth 1 a of the bag 1, and a hanging rope is attached to the insertion portion. 8 is inserted. This is convenient when the bag 1 is held by a support (not shown) such as a support frame.

On the other hand, on the bottom side of the bag 1, the central portion of the bottom of the cloth 1h constituting the bottom is cut into a cross shape, for example, so that the portion can be opened. Further, a cylindrical body 10 for discharging cereals is attached to the open portions 9 and 9. The entire periphery of the base end (the lower end in FIG. 4) of the cylindrical body 10 is sewn to the cloth 1h inside the opening 9. A tightening rope 11 is arranged in a portion of the cloth 1h which can be opened, that is, in the open portion 9, so that the portion can be closed. When grains are stored in the bag 1, the bottom cylinder 10 is closed with a rope (not shown) or the like, and the bottom portion of the bag 1 is closed by tightening the tightening rope 11. In this case, the tubular body 10 tied with a rope or the like may be stored in the bag 1 inside the opening 9. Conversely, when discharging the grains stored in the bag 1, as shown in FIG. 4, the tightening rope 11 is loosened so that the cylindrical body 10 protrudes from the opening 9, and To release. In this case, it is very convenient to discharge cereals from the bottom of the bag 1.

In the drawings, the case where the bag 1 is formed in a rectangular parallelepiped shape is illustrated, but the shape of the bag 1 may be cylindrical. Also in this case, the foldable mouthpiece 3 is attached to the mouth 1a of the bag 1 in the same manner as described above. Then, as in the case shown in FIG.
Of the fabric covering the upper end opening of the bag 1 is sewn to the periphery of the mouth 1a of the bag 1, and the center of the fabric is opened so that the tip of the air duct A can be inserted. Sewn around the mouth, and inserting a hanging rope 8 into the sewn cloth. Also, fasteners 7 and 7 are attached to the cloth covering the upper end of the bag 1 as in the case shown in FIG. 3, or the bottom of the bag 1 is made open as in the case shown in FIG. Attaching the tubular body 10 and the fastening rope 11 can be adopted. When the bag 1 is formed in a cylindrical shape, elastic bars 2, 2 which can be elastically bent may be vertically arranged at three or more places on the side surface of the bag 1. Simply arranging the elastic bars 2 at two places on the side surface of the bag 1 does not make the bag 1 independent.
