Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a prismatic cylindrical transport bag, and more particularly to a prismatic cylindrical transport bag consisting of an inner cylinder and an outer bag, both of which are cylindrical sheets. The purpose is to provide a transport bag that can be easily manufactured using a cylindrical material, and that becomes a rectangular cylinder shape when filled with contents, making it convenient for transportation and storage.

Containers for transporting or storing powdered or granular agricultural products, processed agricultural products, or industrial raw materials include those made of rigid materials such as plates, metals, synthetic resin molded products, etc., and fabrics and synthetic resin sheets. Some are made of flexible materials such as. On the other hand, there are two types of containers: cylindrical and prismatic, and various containers have been proposed depending on the combination of materials and shapes. Among these, the type of contents that should be filled,
Considering ease of handling, price, volume when empty, etc., it is most desirable to use flexible materials such as cloth or synthetic resin sheets, and to have a rectangular cylindrical shape when filled with contents. When using such flexible materials, it is necessary to make the material into a rectangular cylinder shape by some means and maintain this rectangular cylinder shape.For this reason, in the case of conventional materials,
The peripheral wall made of a flexible material is bent in advance to form a rectangular cylinder shape, and perforated support walls are installed at the four corners of this peripheral wall, that is, between adjacent peripheral walls, so that the container can be easily maintained even when filled with contents. , the pre-assigned shape of a rectangular cylinder is maintained.

In this case, it is necessary to bend the bag in advance, and it is necessary to secure perforated support walls by sewing or other means to the four corners of the rectangular cylindrical peripheral wall. , except when it is made of rigid bodies such as wooden boards, metals, etc., and when it is made of flexible materials such as bags,
Stretching and fixing other members made of similar flexible materials to specific locations is an extremely difficult and time-consuming task, and in some cases may require modification of the tightening machine or require complicated work. It can also mean being forced to do something.

In view of these points, the inventor of the present invention has created a container that can be easily manufactured, and has a rectangular cylindrical shape when filled with contents.
As a result of extensive research and various experiments, we have developed a prismatic cylindrical bag that is suitable for transportation and storage, minimizing the gaps that occur between bags during transportation and storage. It is a sheet-like autumn item, and consists of an inner cylinder that is shorter than the outer bag, and an outer bag that is made of a cylindrical sheet-like material whose circumference is four times the diameter of the inner cylinder. The inner cylinder is inserted into the outer bag so that the two lower ends of the inner cylinder are located apart from the upper and lower ends of the outer bag, and when these inner cylinders and outer bag are combined, When the outer bag is square, the purpose can be well achieved by creating a rectangular cylindrical transportation bag in which the inner tube is joined to the outer bag by sewing, gluing, etc. at the point where it is inscribed in the outer bag. It is an invention.

Now, to explain an example of the implementation of the present invention in more detail with reference to the attached drawing +1, ] is an outer bag, 2 is an inner cylinder, and the length H of the outer bag 1 is longer than the length of the inner bag 2. In addition, the circumferential length X of the outer bag 1 is 4 times the h diameter Y of the inner bag 2. Both the outer bag 1 and the inner bag 2 are cylindrical and are made of sheets. This sheet-like material is made of a so-called wari material, which is made by combining continuous VcM layers in the vertical and horizontal directions, such as woven fabric, plastic film, non-woven fabric, or split fibers made by making small cracks in plastic film. There are no particular limitations on these materials or textures, but they are preferably ones that do not stretch as a whole.In the case of woven fabrics, for example, ribbon yarns, tape yarns, etc. In addition, the density of the sheet-like material, that is, the coarseness of the mesh, is arbitrary and varies depending on the type and size of the contents to be filled. If the item is desired to be in good condition, a coarse one is preferable, and if the contents are fine, a tightly woven one is preferable to prevent leakage.Furthermore, when the contents are fine, it is preferable to use a clogged one to prevent leakage. If leakage must not be prevented, but outflow from the inner tube cannot be prevented, it is preferable to use a relatively large container.The inner tube 2 is inserted inside this outer bag 1. However, at this time, the inner cylinder 2 is placed in the middle of the outer bag 1.

In other words, the upper end 3 of the outer bag 1 and the second end 4 of the inner cylinder 2 must not be in a state that the lower end 5 of the outer bag and the lower end 6 of the inner cylinder 2 are the same, and the As shown in Figure 4, if the upper end 3 of the outer bag 1 and the upper end 4 of the inner cylinder 2 are positioned apart, the length of the outer bag l will be longer than the length of the inner cylinder 2. Because of this, the lower end 5 of the outer bag 1 and the lower end 6 of the inner tube 2 naturally come to be in positions apart from each other. In this case, the inner tube 2 is arranged so that the length between the upper end 3 of the outer bag 1 and the upper end 4 of the inner tube 2 is equal to the length between the lower end 5 of the outer bag 1 and the lower end 6 of the inner tube 2. or may be arranged unequally. This outer bag 1 and the inner cylinder 2 inserted into it are combined at a specific point by means such as sewing or gluing. When a square shape is made using a shaping tool, if the inner cylinder 2 is inserted inside the square outer bag 1 while still being cylindrical, the outer bag 1 and the inner cylinder 2 will be As shown in Figure 5, it is inscribed at locations KA, B, C, and D. This is because the circumference of the outer bag 1 is y4 times the diameter of the inner cylinder 2, and the inscribed A, B, C,
It may be sewn or glued at point D. However, in the present invention, the outer bag 1 and the inner tube 2 are A, B, C,
As shown in Figure 6, ic A? ■ Marked A, E, C, D
At the two points A' and A'' equidistant from the contact point, or at the three points A and At8, or at A
' to A'' may be combined,
This is possible because the outer bag 1 and the inner cylinder 2 are not made of a rigid body such as metal, but are made of a sheet-like material that has flexibility and can be easily deformed.

There are various ways to use a transport bag in which the outer bag and inner cylinder are combined in this way, but the simplest way is to tie the lower end 5 of the outer bag 1 with a string, etc., and use it as a bottom. It is sufficient to fill the space between the inner tube 2 and the outer bag 1 with shrinkable materials, as well as the inside of the inner tube 2, and tie the upper end of the outer bag 1 with a string or the like as well as the bottom. Another way to use it is to provide a top wall 7 and a bottom wall 8 on the top and bottom of the combined outer bag 1 and inner cylinder 2 to form the main body of the transporter. An injection barrel 9 and a cover 10 for the injection barrel 9 are attached.

Also, on the bottom wall 8, there is a discharge tube 11 for stored items and a discharge tube 11.
A cover 12 is attached.

The top wall 7 and the bottom wall 8 have the same shape and size, and the length of their peripheral edges is equal to the length of the circumference of the outer bag 1.

In order to attach the top wall 7 and the bottom wall 8 to the main body described above, when the outer bag l and the inner cylinder 2 are combined, one of the combined points, for example A, must be placed at the center of one side of the top wall 7. If the periphery of the outer bag l is sewn along the periphery of the top wall 7, the remaining joining points B, C, and D will match the remaining three sides of the four sides of the top wall 7. It is sewn together. This also applies to the bottom wall 8. The top wall 7 and the bottom wall 8 are preferably made of the same material as the outer bag 1, and the injection tube 9 and its cover 10 and the discharge tube 11 and its clasp 1 are preferably made of the same material as the outer bag 1.
Similarly, the outer bag 2 is preferably made of the same material as the outer bag 1.

The transportation bag according to the present invention is extremely easy to manufacture compared to conventional transportation bags in which partition pieces are provided at each corner of the bag. In other words, the preparation work required to sew partition pieces to each of the internal corners is difficult due to the handling of sewing flexible sheets together, the setting of the sewing points, and the handling of the tightening machine. It is extremely complicated and time-consuming, and work efficiency is inevitably low. On the other hand, in the case of the present invention, it is only necessary to determine y4 equal dividing points on the circumferences of the inner cylinder and outer bag, and to determine the four equal dividing points, for example, the outer bag is made square and the inner cylinder is inserted into it. Once the contact points are determined, or simply by folding the bag in half and then folding this in half again, there is nothing difficult about it, and if you combine these four equally divided points by sewing or gluing, you can create the main body. Since these are constructed, the work for combining them is simple and easy to handle, resulting in a marked improvement in work efficiency.

In addition, in conventionally known partitions, the partitions provided at the internal corners must be provided with holes through which the stored items can flow, which reduces the strength of the partitions. The fibers of the woven fabric that makes up the partition pieces are exposed at the inner peripheral edge of the flow hole, and these fibers may become waste and mix into the stored items, damaging the quality of the stored items. However, since the inner cylinder of the present invention does not have a flow hole or a similar structure, the original strength of the inner cylinder can be maintained as it is, and there is no risk of its deterioration. Moreover, since there are no broken parts such as communication holes, there is no fiber waste generated therefrom, so the quality of the stored items will not be impaired. The transport bag of the present invention consists of an inner and outer part made of a simple cylindrical sheet-like material, and just by filling it with the stored items, the outer bag automatically becomes a square shape and the inner tube is inscribed in this square outer bag. Since it maintains its shape as a transportation bag, it can be stacked and stored tightly with the least amount of space between the bags during transportation and storage.
This is an epoch-making invention that allows transport bags of the most preferred form to be stacked together to be provided extremely easily, efficiently, and at low cost.
