Description

  The present invention relates to a flexible container bag (hereinafter abbreviated as “container bag”) used for storing and transporting powder, granular materials, earth and sand, and the like.

When a large number of container bags are arranged in a plurality of rows and columns, a cylindrical container bag has a larger installation area than a rectangular bag.
For example, when storing and transporting a large amount of earth and sand in a container bag, it is preferable to use a square container bag to improve transport efficiency and storage efficiency, but it is also used as a large sandbag. Many container bags with heavy weight resistance are cylindrical, and those that are formed in a square shape also swell and become cylindrical when the contents of the container bag are inflated. .

  As shown in FIG. 6, as a container bag provided so as to be held in a square shape even when it is filled with granular powder such as resin pellets, the trunk of the container bag 100 formed in a square shape. Inside the four corners 102 of the part 101, a vertically long partition sheet 104 having a length extending from the bottom of the ceiling sheet to the top of the bottom sheet 103. 101, the two side ends of each partition sheet 104 are fastened to the inner surface of the body portion 101, and the inside of the corner portion 102 is formed in a substantially triangular space by the partition sheet 104 in plan view. The thing of the structure provided so that it might partition is known (for example, refer patent document 1).

  Decontamination work is being conducted on soil contaminated with radioactive materials released in the previous nuclear accident. Soil decontamination is done by removing the surface layer of contaminated soil using a heavy machine, or by spraying a solidifying agent on the soil and then stripping off the surface layer and removing the removed soil in a large container bag. It is planned to be packed and sealed, and stored in a temporary storage area, stored for a predetermined period, transferred to an intermediate storage facility for volume reduction, and then disposed of at the final disposal facility. Despite the widespread soil contamination by radioactive materials and the expectation that a large amount of contaminated soil will be generated by stripping off the topsoil, a sufficient temporary storage space for storing container bags filled with contaminated soil can be secured The actual situation is not.

In order to install as many container bags filled with contaminated soil as possible in a temporary storage place where space is limited, square container bags should be used. When the earth and sand are also packed into the mold, the peripheral surface of the trunk portion swells into a columnar shape, and the storage space is not effectively used.
In the container bag 100 having the rectangular shape shown in the figure, the partition sheet 014 has a length extending from the lower side of the ceiling sheet to the upper side of the bottom sheet, and there is no problem in filling the granular powder. However, when trying to pack the earth and sand containing large and small lump using heavy equipment, it is difficult for the earth and sand to enter the space inside the corner portion 102 partitioned by the partition sheet 104, and the container bag 100 is filled with the earth and sand. When filled in, there is a problem that a gap is formed inside the corner portion 102 and is crushed, and the whole becomes a substantially cylindrical shape and cannot be held in a square shape. In addition, since the conventional container bag 100 has the partition sheet 104 provided inside the bag and the suspension belt provided on the outer surface of the bag separately sewn, it requires labor for the sewing work and increases the manufacturing cost. I had to be.

In addition, in the current situation where there is not enough temporary storage space, the container bag filled with contaminated soil is brought to an outdoor storage place different from the temporary storage space until the temporary storage space is constructed, and the contaminated soil is filled. The surrounding container bag is temporarily stored in a state surrounded by a large sandbag filled with uncontaminated soil.
Although the storage at this storage location is short, the container bag is placed outdoors, so the sewing part of the hanging belt attached to the outer surface of the trunk of the container bag is easily deteriorated by receiving ultraviolet rays, and is constructed. When the suspension belt is pulled up by a crane or the like to transport the container bag to the temporary storage place, the suspension belt may be torn off from the trunk of the container bag, and the container bag cannot be transferred.

  SUMMARY OF THE INVENTION In view of the above-described problems of the prior art, the present invention is configured so that a container bag can be held in a square shape even when earth and sand are fully filled therein to store and transport a large number of container bags. Container bag that has been stored outdoors so that the attachment part of the hanging belt does not deteriorate even if the container bag filled with the contents is stored outdoors. It is an object of the present invention to enable safe transport using a crane or the like.

In order to solve the above-mentioned problems, the present invention provides a container bag having a barrel portion formed in a square cylindrical shape , wherein a plurality of strip-shaped partition pieces are arranged from the upper end to the lower end of the corner portion. It is arranged so as to be spaced from each other and straddle between both side surfaces adjacent to each other with a corner portion interposed therebetween, and each end portion is fixedly attached to the inner surface of each side surface, and each partition piece is attached It has a configuration in which the inside of the corner portion is partitioned into a space of a substantially right triangle in plan view by both side surfaces sandwiching the corner portion and a partition piece.

According to this, inside the four corners of the body of the rectangular container bag, the partition pieces are arranged so as to straddle the corners horizontally, and both ends of the partition pieces are placed on the sides of the body on both sides of the corners. Since the container bag is filled with the contents, the sides on both sides of the corners will not spread outward even if the contents are exposed to the outer circumferential side of the container bag. The part is held at a substantially right angle, and the body side surface is prevented from deforming so that it swells outward, and the contents fill the space of a substantially right triangle in plan view inside the corner divided by the partition pieces. By doing so, the container bag can be held in a square shape.
In addition, inside the four corners of the body part, a plurality of partition pieces are attached at appropriate intervals from the upper end to the lower end of the corner part. Even in the case of packing in a container bag, the earth and sand can smoothly enter the space inside the corner through the gap between the upper and lower partition pieces, and can be packed into the four corners of the trunk without any trouble. When the container bag is fully filled with earth and sand, there is no gap in the space inside the corner, and the corner does not collapse or bend.

In the container bag having the above-described configuration, two or more, more preferably three or more strip-shaped partitions are provided inside each corner so that the corner is held at a substantially right angle from the upper end to the lower end. It is preferable that the pieces are fixed at equal intervals from the upper end to the lower end of the corner.
Moreover, in order to allow the contents to smoothly enter the entire space inside the corner section partitioned by the partition pieces, the arrangement interval (S) of the partition pieces from the upper end to the lower end of the corner section is It is preferable that the width is approximately the same as the length of the short width (W) (S≈W) (see FIG. 4A).

In addition to the above configuration, the container bag according to the present invention has a suspension belt folded in half at each of the four corners of the body, and both ends of each of the partition pieces are inside the side surfaces on both sides of the corner. It is characterized by having a configuration in which both ends are overlapped and attached to the inner surface of the side surface extending from the lower part to the upper part of the body part .

  According to this, since the hanging belt is attached not to the outer surface of the body portion but to the inside of the body portion, even if the container bag filled with the contents is stored outdoors, the hanging belt The attachment portion is not directly irradiated with ultraviolet rays, so that the attachment portion can be prevented from being deteriorated by receiving ultraviolet rays, and the container bag can be safely transferred by hanging the suspension belt with a crane or the like.

  In the container bag having the above structure, the suspension belts are fixed to the insides of the four corners of the body part, and the four fastening belts are fixed to the adjacent corners. The two suspended belts and the other two suspended belts can be connected to each other by a coupled suspension belt. In this case, the container bag can be transferred by suspending the two connecting suspension belts with a crane.

The present invention uses a sheet and belt woven with synthetic fibers such as polypropylene, polyethylene, and polyethylene terephthalate, and fastens them together, and is applied to a bottomed rectangular container bag whose upper part is open in a plan view. can do. The capacity of the container bag is not limited and can be formed to an appropriate size.
In addition, as means used for fastening the sheets constituting the body part and the bottom part and fastening the suspension belt to the body part, appropriate means such as sewing, heat fusion, and adhesion can be used.
The container bag of the present invention can be used for packing, storing, and transporting granular powders such as earth and sand, grains, and feed, or can be used as a sandbag, and the type and use of the contents to be filled are not limited.

According to the container bag of the present invention, the contents containing a lump such as earth and sand can be filled smoothly and without wrinkles, and the whole is held in a square shape with the contents filled, It is possible to efficiently use the space used for container bag storage and transportation without waste.
In addition, since the suspension belt is fixed inside the container bag, the fixed portion of the suspension belt is not deteriorated by receiving ultraviolet rays when the container bag is stored outdoors. The container bag can be safely transported by hanging the service belt.
In addition, the partition piece and the suspension belt are fastened in advance, and this is placed in the container bag and fastened together, so that the work of attaching the partition piece and the suspension belt can be reduced. Bag processing costs can be kept low.
