た。2. Description of the Related Art Currently used medical bags are formed by cutting an inflation tube having a thickness of 100 to 600 .mu.m into a predetermined length and injection molding a thermoplastic tube into the opening of the tube. It is manufactured by inserting a plug part made of resin, fusion-sealing the opening portions at both ends of the tube into a flat plate shape with a mold, and forming a bag portion between the fusion-bonding portions. Both surfaces of the fusion-bonded portion were formed flat, or both surfaces were formed with a convex portion and a concave portion having a uniform depth H of the embossed surface.

グしやすい等の問題があった。However, in the case of a medical bag in which both surfaces of the fusion-bonded portion are formed flat, both ends of the tube are overlapped with each other and the tube is pressed by the mold to be fused. -Easy to bite the air into the overlapping parts. Also, if the mold is pressed too hard, the wall thickness becomes thin and the strength of the fused portion tends to be weakened. Furthermore, when handling a medical bag filled with a drug solution, it is easy to slip and drop. During high-pressure sterilization, there was a problem that the bags were likely to block each other.

調整を行う必要があるがこれが困難であった。Further, in the case of a medical bag in which a convex portion and a concave portion are formed on both surfaces of the fusion-bonded portion, when the positions of the concave portion on one surface and the concave portion on the other surface are overlapped with or close to each other, the overlapping tucks are formed. Some of the buds become extremely thin. On the other hand, when the convex portion on one surface and the convex portion on the other surface overlap or come close to each other, a thick portion is formed in a part of the overlapping tubes,
When fusion is performed by pressing with a die, the fusion cannot be completely completed and an unfused portion between the tubes is formed. When the depth of the embossed surface is uniform, air is easily caught in the folds at both ends of the tube, and tunnel leak is performed. In order to prevent this, the portion of the mold that comes into contact with the fold portion of the tube is formed in a convex shape so that the air is pushed out so that it strongly hits the fold portion of the tube. If the crease of the tube hits the concave part of the mold, air-
After all, it was easy to leak tunnels. It is necessary to finely adjust the positioning of the mold so that the tunnel leak does not occur, but this is difficult.

If formed on the folds at both ends of the bag, a tunnel-shaped hole may be opened from the inner surface of the bag to the outside of the bag, and the liquid content may leak. Therefore, the present inventor has arrived at the next invention as a result of intensive studies to solve the above problems.

No. 39, Japanese Patent Application No. 4-98740 and Japanese Patent Application No. 4-165.
As proposed in No. 424, the recesses of the fusion-bonding part formed at the end of the bag are regularly arranged in a vertical line, so there is a very low probability that the recesses will not be on the line of the end of the fusion-bonding part. As a result, it is assumed that the bag will not be pressed down properly and will cause a leak. Therefore, the present inventor has arrived at the next invention as a result of earnest studies for solving the above problems.
