Description

  The present invention relates to a cereal storage bag for storing cereals, and more particularly to an inner bag for a cereal storage bag that is used by being placed inside a cereal storage bag.

  Conventionally, various cereal storage bags are used for storing and transporting and storing cereals such as rice and wheat. For example, a cereal storage bag is known which has a cylindrical bag wall and a bottom provided with a cereal outlet in the center, and is configured to stand on its own without using a separate auxiliary tool in order to prevent sideways fall. (Patent Document 1). And the grain storage bag is made into the mesh structure which has air permeability at least so that a bag wall body may be stored in the state which accommodated the grain.

  Such a grain storage bag has an advantage that grains having different harvesting periods can be stored and used throughout the year. For example, wheat can be stored and stored for a certain period during the summer wheat harvesting period, and then stored and stored for a certain period during the autumn rice harvesting period.

  However, since wheat has a long hair compared to rice, when wheat is stored in a cereal storage bag, the field hair is caught in the mesh structure, and many wheat grains remain in the bag even after the wheat is discharged from the bottom. . When rice is stored in a cereal storage bag in which wheat is stored, there is a problem that the wheat remaining in the bag is mixed with the rice and lowers the grade of the rice.

  Therefore, the present invention has been made for the purpose of solving the above-described conventional problems, and is placed inside a conventionally used cereal storage bag to store cereals with relatively long hairs such as wheat. A special inner bag is provided so that long-haired cereals do not remain in the cereal storage bag serving as the outer bag.

  In order to achieve the above object, the present invention employs an inner bag of a grain storage bag having a structure in which a substantially cylindrical bag wall has a mesh structure and a grain outlet is provided at the center of the bottom. A cylindrical bag wall support in which a plurality of vertically formed frames are sequentially coupled with adjacent longitudinal vertical frame portions adjacent to each other, and a mesh for each frame of the bag wall support An inner bag wall configured by stretching the dough, and an inner bag bottom having a grain discharge portion provided along a lower edge of the inner bag wall, wherein the mesh dough is the cereal storage bag It is in the point which set it as the structure which has a finer mesh than the mesh structure of this. Therefore, when the inner bag is mounted inside the cereal storage bag, the inner bag wall body is self-supporting by the bag wall support, and the upper opening of the inner bag is arranged near the opening of the cereal storage bag. Storage work is easy to perform. Moreover, because the inner bag wall is stretched with a mesh fabric finer than the mesh structure of the grain storage bag, when storing grains with relatively long hair such as wheat, the field hair and grains are stored in the grain storage bag. Can be prevented from adhering to the mesh structure.

  Further, in a more preferred aspect of the inner bag, the frame body is a vertically long oval shape, and the mesh fabric is stretched substantially horizontally near the uppermost point of the curved frame body of the bag wall support, The upper opening edge of the inner bag wall is formed substantially horizontally. In this case, it is possible to prevent cereals from overflowing from the valley-shaped edge of the bag wall support formed by connecting a plurality of frames in a cylindrical shape.

  As described above, in order to make the upper opening edge of the inner bag wall body a substantially horizontal opening edge, the inner bag wall body is stretched in the frame of each frame body constituting the bag wall support body. The mesh fabric for the inside of the frame, the mesh fabric for connecting the upper portion of the frame connecting the adjacent edges of the upper portion of the curved frame and filling the valley-shaped edge of the bag wall support, and the adjacent edges of the lower portion of the curved frame And a mesh fabric for connecting the lower part of the frame body that connects the portions and fills the valley-shaped edge of the bag wall support, or one mesh fabric for the side surface of the bag wall support. It may be constructed by stretching.

  Moreover, the still more preferable aspect of the said inner bag forms the said cylindrical bag wall support body by couple | bonding an even number of said frame bodies sequentially, while forming the said frame body with an elastic material, and adjoining frame bodies Is to be foldable through the mutual coupling part. As a result, the frame can be folded so as to be stacked, and the frame is made of an elastic material, so that the entire inner bag can be folded compactly by bending while twisting the stacked frames. Can do.

  According to the inner bag for a cereal storage bag according to the present invention, for example, when storing cereals with relatively long hairs in a cereal storage bag, the inner bag is placed in the cereal storage bag and the cereal is stored in the inner bag. By storing the cereal, the outer cereal storage bag has a structure in which cereals having a long hair are not attached. Therefore, when storing different types of cereals after that, if the inner bag is removed from the cereal storage bag and stored directly in the cereal storage bag, there is no cereal with long no hair remaining in the cereal storage bag. Therefore, other cereals are not mixed, and the grade reduction of cereals can be prevented. Moreover, since the inner bag is self-supporting due to the action of the bag wall support, it has a structure that facilitates the grain storage work in the inner bag.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a view showing an inner bag 1 for a grain storage bag according to the present embodiment, and FIG. 2 is a view showing a state in which the inner bag 1 is mounted inside a grain storage bag 2. As shown in FIG. 2, the inner bag 1 is detachable inside the grain storage bag 2. For example, when storing grains having relatively long hairs in the grain storage bag 2, the inner bag 1 is attached to the grain. It is used in the form of being housed in the inner bag. The cereal storage bag 2 serving as an outer bag has a configuration similar to that of the prior art, and has a substantially cylindrical bag wall 21 and a bottom 23, and a lid for closing the upper opening 21 a at the upper edge of the bag wall 21. 22 is provided, and the bottom portion 23 is provided with a cylindrical discharge portion 24 for discharging cereals by natural fall, and the discharge portion 24 is squeezed on the side surface of the discharge portion 24 to prevent the cereal from falling. A binding string 25 is provided. The bag wall 21 of the cereal storage bag 2 is formed, for example, as having air permeability suitable for storage of cereals by a mesh structure 26 integrally formed in a sheet shape by intersecting a large number of polyester filament yarns. Further, the mesh of the mesh structure 26 is formed to have a size that does not allow grains to pass. In addition, although illustration is abbreviate | omitted, the grain storage bag 2 is provided with the support means which supports the bag wall 21 so that it may become independent without using an auxiliary tool etc. separately.

  As shown in FIG. 1, the inner bag 1 attached to the cereal storage bag 2 includes a tubular inner bag wall 3 and an inner bag that is sewn along the lower edge of the inner bag wall 3. The bottom part 4 is provided with a cylindrical discharge part 5 for discharging the cereals by natural fall at the center of the inner bag bottom part 4, and the discharge part 5 is squeezed at an appropriate side of the discharge part 5 to cease the grains. In order to prevent the fall, a band 11 provided with hook and loop fasteners 12 and 13 at both ends is attached. The inner bag wall body 3 includes a cylindrical bag wall support body 7 constituted by a plurality of frame bodies 6 formed in a vertically long oval shape using an elastic material such as glass fiber. Since each frame body 6 has a vertically long oval shape, its upper and lower portions have a shape that is curved in a substantially semicircular shape, and its middle portion is a vertical frame portion that is substantially linear in the longitudinal direction. ing. Such a frame body 6 can be formed, for example, by squashing a circular annular elastic frame body from the lateral direction and flattening it vertically. The bag wall support 7 is formed in a cylindrical shape by sequentially joining the straight vertical frame portions of the frames 6 next to each other. The inner bag wall 3 includes a bag wall 8 in which a mesh fabric having air permeability is stretched over each frame 6 constituting the bag wall support 7. In the present embodiment, the case where the regular hexagonal bag wall support 7 in plan view is configured by using six frames 6 is illustrated, but the number of the frames 6 is not limited to this, and N (however, , N is preferably 3 or more), and a cylindrical bag wall support 7 having a regular N-gonal shape in plan view may be configured. The outer diameter of the inner bag wall 3 is preferably formed to be the same as or slightly smaller than the inner diameter of the cereal storage bag 2.

  As described above, the bag wall support 7 is formed in a cylindrical shape by joining the vertical frame portion of the vertically long frame 6 that is substantially linear to the vertical frame portion of another adjacent frame 6. However, a patch fabric 9 having a predetermined width is sewn along the vertical frame portion at the joint portion, and the joint portion is reinforced by the patch fabric 9. And the bag wall support body 7 with which the several frame body 6 was combined in the cylinder shape supports the inner bag wall body 3 so that it can become independent.

  Further, as described above, the bag wall support 7 has a configuration in which a plurality of frames 6 formed in a vertically long oval shape are combined, so that the upper edge and the lower edge are not in a horizontal state, The circularly curved frame bodies are connected to each other, and in particular, the edge portion at the joint portion of the two frame bodies 6 forms a substantially V-shaped valley-shaped edge portion. Therefore, the bag wall 8 formed by stretching the mesh fabric on the bag wall support 7 forms a substantially horizontal upper edge portion in the vicinity of the uppermost point of the upper part of the curved frame body of each frame body 6. To fill the upper valley-shaped edge of the bag wall support 7 and to form a substantially horizontal lower edge near the lowest point of the lower curved frame body. It is provided so as to fill the mold edge and make the upper and lower edges of the inner bag wall 3 substantially horizontal. Thereby, the upper opening edge 10 of the inner bag wall 3 is formed as a substantially horizontal opening edge in the vicinity of the uppermost point of the upper part of the curved frame body of the frame body 6, and it is possible to prevent the grains from falling from the valley-shaped edge. . The bag wall bottom 4 is sewn along the substantially horizontal lower edge of the inner bag wall 3.

  The mesh fabric constituting the bag wall 8 of the inner bag 1 is a fabric having a finer mesh than the mesh of the mesh structure 26 provided in the cereal storage bag 2. For this reason, even if the grain hair of the cereal is stuck into the bag wall 8 of the inner bag 1, the inner bag 1 is removed from the cereal storage bag 2, so that no cereal remains in the cereal storage bag 2. It is more preferable that the bag wall 8 is formed using a mesh fabric having a mesh smaller than the diameter of the corn grain hair stored in the inner bag 1 so that the corn grain hair does not penetrate the outside of the bag wall 8. In addition, you may comprise the inner bag bottom part 4 and the discharge part 5 using the mesh fabric similar to the bag wall 8. FIG.

  FIG. 3 is a view showing an example of a state in which the inner bag 1 is developed. The bag wall 8 connects the in-frame mesh fabric 8 a that is stretched within the frame of each frame body 6 and the adjacent edge of the upper portion of the curved frame body, and fills the valley-shaped edge of the bag wall support 7. The substantially triangular frame upper part connecting mesh fabric 8b and the adjacent lower edge of the curved lower part of the frame are connected so as to fill the valley-shaped edge of the bag wall support 7. It consists of a triangular frame body lower connecting mesh fabric 8c, which is joined to the bag wall support 7 and sewn. The inner bag bottom part 4 is formed in a regular hexagon according to the shape of the bag wall support 7, and the middle point of the lower edge of the frame lower part connecting mesh fabric 8 c is joined to each vertex. A cereal discharge port 4a is provided at the center of the inner bag bottom 4, and a cylindrical discharge unit 5 is sewn to the discharge port 4a. The in-frame mesh fabric 8a to be stuck in the frame of each frame body 6 is individually stuck to each frame body 6 in advance before the cylindrical bag wall support body 7 is formed. You can leave it. Moreover, although the case where mesh fabric 8a, 8b, 8c is provided in the bag wall support body 7 is shown in the example of the figure, it is not limited to this. For example, a single mesh fabric in which the mesh fabrics 8a, 8b, and 8c are integrally formed is prepared, and the single mesh fabric is stretched on the side of the bag wall support 7 to form the bag wall 8. May be.

  When the inner bag 1 having the above configuration is attached to the inside of the cereal storage bag 2 to store cereals having relatively long hair such as wheat, the inner bag 1 with the discharge portion 5 squeezed as shown in FIG. Is placed inside the cereal storage bag 2, and cereals with relatively long hairs are stored in the inner bag 1. At this time, since the grain hair of the cereal does not come out of the inner bag 1, the grain or field hair does not adhere to the mesh structure 26 of the grain storage bag 2. And when discharging | emitting grain, the aperture | diaphragm | squeeze of the discharge part 5 is open | released and the grain accommodated in the inner bag 1 is discharged | emitted from the discharge part 5 by natural fall. Then, when storing other cereals such as rice in the cereal storage bag 2, the inner bag 1 is removed from the cereal storage bag 2, and the cereal is stored directly in the cereal storage bag 2. Even if wheat remains in the inner bag 1 at this time, since the inner bag 1 is removed from the cereal storage bag 2, the cereal storage bag 2 without residue is obtained. Even if the rice is stored, the wheat does not enter the rice, and the problem of lowering the grade can be solved.

  The bag wall support 7 in the above-described inner bag 1 has a configuration in which adjacent frame bodies 6 can be folded via each other's coupling portion. And since each frame 6 is formed with the elastic material, when it removes from the grain storage bag 2, the inner bag 1 becomes a structure which can be folded compactly. FIG. 4 is a view showing an example when the inner bag 1 is folded. First, the bag wall support 7 of the inner bag 1 is folded from a three-dimensional cylindrical state into a planar form to obtain the state shown in FIG. Then, as shown by arrows A1 and A2, the left and right frame bodies 6 are folded in the center, and as shown in FIG. 4B, a plurality of frame bodies 6 are stacked in one. Then, as shown by arrows B1 and B2, the upper portion of the stacked frame body 6 is bent while being twisted and overlapped with the lower portion to obtain the state shown in FIG. In this state, the vertical dimension of the frame 6 is reduced to about half. Then, as shown by the arrow C1, the compact frame 6 is bent toward the discharge portion 5 to obtain the state shown in FIG. Thus, if the inner bag 1 folded compactly is stored and stored in a dedicated storage bag or the like, the storage space when the inner bag 1 is not used can be reduced. However, as described herein, in order to make the inner bag 1 foldable in a compact manner, it is preferable that the number of frames 6 constituting the bag wall support 7 is an even number.

  As described above, the inner bag 1 is configured as a dedicated inner bag that is used while being attached to the inside of the cereal storage bag 2, and is presupposed to be attached to the cereal storage bag 2 when in use. Therefore, even when storing grains of several hundred kilograms to 1 ton or so, the grain storage bag 2 has a strength capable of withstanding its weight, so the inner bag 1 does not have to have such a high weight resistance, and the grains Compared to the storage bag 2, it can be produced at a low cost. Moreover, since the inner bag 1 is self-supporting due to the action of the bag wall support 7, the upper opening edge 10 of the inner bag 1 is positioned at substantially the same height as the upper opening 21 a of the cereal storage bag 2 when attached to the cereal storage bag 2. That is, the structure is such that it is easy to store the grains in the inner bag 1, and the bag wall 8 of the inner bag 1 is made of a fabric that is finer than the mesh of the mesh structure 26 provided in the grain storage bag 2. As a result, cereals with long hairs do not adhere to the cereal storage bag 2. When the inner bag 1 is not used, it can be stored in a narrow space by being compactly folded as described above.

It is a perspective view which shows the inner bag for cereal storage bags. It is a figure which shows the state which mounted | wore the grain storage bag with the inner bag. It is a figure which shows an example of the state which expand | deployed the inner bag. It is a figure which shows an example in the case of folding an inner bag.
