されている。2. Description of the Related Art Conventionally, among flat bag containers having opposing flat surfaces, those which heat seal around four sides of a bag (four-side sealed bags) are made of a film material which is a material of the flat bag container. Processing can be performed by making the transport direction and the flow direction of the zipper part the same, and from the viewpoint of improving productivity, containers with zippers have been conventionally manufactured by this method. In recent years, devices other than the four-sided seal have been devised to attach a zipper, and separately from the bag body portion of the bag, a cap bag-like member provided with a zipper portion is provided in advance as if a hat is put on. Containers made by the method of deposition have been proposed.

化するうえで好ましくないという問題もある。However, the gusset bag has a problem that it is difficult to attach the zipper, especially since the gusset has a folded portion. Therefore, it is conceivable to cut off a part of the folded portion.For example, in the method of forming an open surface at the mouth of the bag and cutting off the folded portion, when the folded length of the folded portion is large, the drawing length of the folded portion is also reduced. There is also a problem that it is not preferable in terms of mechanization of the manufacturing process because it becomes large.

且つ確実に行うことができる。In the present invention, the bag has a pair of opposing flat portions constituting the front side and the rear side of the bag, and two side surfaces formed so as to have a folded portion folded inwardly. The folded portion of the tubular bag body is cut off from the end of the mouth at a predetermined position inward along the mounting direction of the zipper, and the cut end of the folded portion constitutes a pair of males constituting the zipper. While being held down by one of the mold chuck tape and the female chuck tape, the fuser tape is fused to one of the pair of opposed flat portions. For this reason, for example, cuts are made inward from the four corners at the mouth end of the bag body, and each flat portion and each folded portion are pushed open to the outside of the bag to form an open surface. The attachment of the zipper can be performed more easily and more reliably than in the case where the zipper is attached by fusing either the male chuck tape or the female chuck tape to the exposed surface of the zipper.

れるように折り畳むことにより形成される。The gusseted bag 1 with a zipper is manufactured through the following steps. First, as shown in FIG. 5, a pair of opposed flat portions 11, which constitute the front side and the rear side of the bag,
11 and a folded part 2 folded inward in a fold shape
2, two side portions 23 formed to include

が困難になる。Next, as shown in FIG. 6, the two opposing seal portions 24 of the seal portion 24 of the bag main body 10 are separated by a predetermined length from the end on the mouth Q side of the bag toward the bottom of the bag. The flat portions 11 and 11 and the side portions 2 are cut by a predetermined length from the mouth end of the bag by cutting only toward the inside of the bag.
3 and 23 are separated. That is, in this step, it is necessary to cut off a part of the seal portion 24 over a width wider than the seal width W of the seal portion 24. If the width of the cut-off is smaller than the seal width W, it is not possible to separate the flat portions 11, 11 from the side portions 23, 23. Therefore, in the next step, the folded portions 22, 22 are connected to the mouth end of the bag. It is difficult to cut off the zipper at a predetermined position inward from the zipper in the mounting direction.

The inner surface of one of the pair of flat portions 11 is fused to the inner surface of one of the pair of flat portions 11 so as to hold the end portion, and the other zipper tape is attached to the inner surface of the other flat portion 11 at a position facing the one zipper tape. We fuse.

The folded portion of the cylindrical bag body having two side surfaces is cut off from the end of the mouth at a predetermined position inward along the mounting direction of the zipper, and the cut end of the folded portion forms the zipper. Since it is fused to one of the pair of flat portions facing each other while being held down by one of the pair of the male chuck tape and the female chuck tape,
No member is required to hold the end of the fold,
Moreover, the attachment of the zipper is easy and reliable.
