2. Description of the Related Art Conventionally, a large-sized flexible bag container (hereinafter, appropriately referred to as a flexible container), which is generally called a flexible container, has been widely used for transporting a large amount of powder and granules. The features of this flexible container are as follows: (1) It is made of a flexible material, has a low tare (empty weight), and is 1/1 when not used.
It can be folded to a volume of 0 or less, making it easy to return and store empty bags. (2) It has a function that allows one person to fill and discharge the contents. (3) No special cargo handling equipment is required and cargo handling can be easily performed with a forklift or crane. (4) It has a function not only for transportation but also as a storage bag. The powders used as contents are also widely used for chemical products, synthetic resin raw materials, ceramics and clay products, feed, foods, etc., and the demand is expected to increase in the future. You.

FIG. 12 shows an example of a conventional flexible container. Reference numeral 10 denotes a flexible container main body, which has a filling port 12 as an inlet at an upper portion (top) and a discharge portion 13 as a discharge port at a lower portion (bottom). 16 is a hanging rope, 20 is a hanging belt, and 22 is a string for binding and sealing. In some cases, the suspension belt 20 may be directly extended instead of the suspension rope 16 to form a suspension belt.

As described above,
While the flexible container has various features, it also has the following disadvantages at the same time due to its flexibility, which is one of the features. (1) Loading and storage during storage and transportation in a warehouse are generally performed in two-stage stacking using pallets for effective use of space. There is a danger that the bag container may be deformed, sacked, or in the worst case may be injured from the spill of the bag container from the pallet. (2) Flexible containers use pallets,
Storage, transportation, etc. are performed, but the contents discharge section of the flexible container is located at the bottom, so the area around the discharge section is easily contaminated from the outside, and foreign substances enter the contents at the time of discharge There is danger.

[0005] As a countermeasure against the above-mentioned problem (1) (load collapse accident), a large bag container using a cardboard case as shown in FIG. 13 is used. This large-sized bag container has a simple structure in which a large-sized bag with an opening on one side is stored as a bag body 26 in a cardboard case 24.
28 is a bottom plate of the cardboard case. Although the large bag container shown in FIG. 13 has a certain effect on the unloading, it does not take into consideration the easy discharge of the contents, which is a characteristic of the flexible container. The discharge must be performed using a special suction device (not shown) from the upper surface filling port 12.
