Description of the Related Art A bag in which a side fold body is provided at a peripheral portion of a sheet-like base body having a storage side and a lid side which are continuously formed and which can be opened and closed when the base body is folded. The side gusset body is provided only on the accommodation side of the (see FIG. 4 (a)), and the side gusset bodies are arranged so as to overlap with each other on both the accommodation side and the lid side when the bases are folded. There is one provided (see FIG. 4 (b)), and as a means for attaching the side gill body to the base body in these, a state in which the base end portion of the side body body to be attached to the base body is directed inward It is usually practiced to place it on a substrate and then heat the substrate while pressing the base end portion from above with a welding machine to integrally weld the substrate. The reason why the base end portion of the side gusset body is arranged so as to be inwardly welded in this way is that the welding machine is attached to the side gusset as the base end portion is arranged inwardly. Since it is located inside the body, it can be confirmed whether or not the base end portion is protruding from the outside during welding, and since the side gusset is located outside the welding machine, It is very easy to remove the side gusset from the welding machine.Furthermore, it is easier and more reliable to install the side gusset on the outside of the welding machine. This is because it is extremely preferable.

生じてしまうこととなる。However, the means for attaching the side gusset body to the base body by such welding is surely the method of welding the side gusset body to the base body if the base body and the side gusset body are materials that are easily welded to each other. It can be done without problems, but on the other hand,
Since the side body and the base body are basically required to be materials that can be welded to each other, the materials of the base body and the side body to be combined are necessarily limited to those having similar properties. It is not preferable because it is difficult to combine two materials with different textures in a wide variety of things, and the freedom of design with little change in design is lost. Further, since the side gusset is directly welded to the base body, when the base body is transparent or translucent, the welded base end of the side fold body is exposed through the base body to the opposite side. However, it is not desirable because it does not look good. Furthermore, since the welded portion exists inside the accommodation side, an unnecessary weld step is generated.

As described in No. 39423, it is difficult to weld the base body and the side gusset body by previously attaching the joint body made of a material that can be welded to the side wing body to the base body and welding the joined body and the side gusset body. It has been considered to make it possible to perform welding without problems even when the materials are different materials, and to solve the problem that the base end portion is transparent due to the attached joint body.

基体の内側へややずらすようにする必要がある。However, in the means in which the joined body is attached in advance, various disadvantages are caused depending on the width of the joined body attached to the peripheral portion. After all it is not desirable. That is, when the width of the joined body is such that the base end portion of the side gusset has only a narrow width that can be welded to the last, the side gusset body is erected at the marginal edge in the conventional welding means. Since it can be welded only by the lid, the lid side does not fit well with the accommodation side when the bags are closed, and as shown in FIG. 5 (a), the lid side shifts and enters the accommodation side and is crushed. Like this,
Alternatively, as shown in FIG. 6A, there is a possibility that the lid side and the accommodation side side gullies are present at the same position, so that the lid cannot be closed. It becomes a thing. Therefore, in order to eliminate this fear, as shown in FIG. 5 (b), a wider range of bonded bodies made of materials that can be welded to the side gusset m>
It is provided as l and the standing position of the lateral gland is slightly shifted to the inside of the base body, or as shown in FIG.
It is necessary to provide a wider joint m '>l' made of a material that can be welded to the side gusset on the accommodation side so that the standing position of the side gusset is slightly displaced to the inside of the base body.

なってしまうためやはり好ましくない。[0006] However, if the width of the bonded body is widened unnecessarily, many wrinkles will be generated at the time of mounting the bonded body at the peripheral corners of the base body, which makes it difficult to perform the bending mounting work. , The peripheral corners cannot be covered neatly, and the wrinkles that occur cause only the peripheral corners of the joined body to become thick, making it difficult to evenly weld the side gussets to the joined body. It causes inconvenience such as a thing. Therefore, in order to eliminate this wrinkle and cover it neatly, when the bonded body is attached at the peripheral edge while pulling the bonded body forcibly, the peripheral corner of the base body may be distorted (see FIG. 56)), or the bonded portion at the peripheral corner is damaged (Fig. 8).
(See (66)). In addition, the joined body at the peripheral corner portion may be neatly folded and covered (see FIG. 9 (76)), or the joined body may be cut once at the peripheral corner portion, changed in direction, and then covered again ( As shown in FIG. 10 (86)), the attachment of the joined body becomes complicated and it takes a considerable time, and the peripheral corners have a thickness (step) and are difficult to be flatly welded. After all, it is not preferable because it will happen.

By this, in a bag which can be closed and opened and which is formed so as to stand upright on the peripheral portion of the base body, the side body is attached to the base body with the base end portion facing outward. The housing body and the lid side are formed by bending the sheet-shaped base body, and then the side fold body is formed so that the base end portion of the base body faces outward at the peripheral edge portion of the base body. Is attached to the peripheral portion of the base body so that the side folds are erected. At this time, the side body is provided only on the accommodation side of the base body, and is also provided on both sides of the accommodation side and the lid side of the base body. The side body is provided only on the accommodation side of the base body. In the case of the sheet-shaped base body, the side body is attached to the accommodation side peripheral portion of the sheet-shaped base body so that the base end portion of the sheet-shaped base body faces outward. On the other hand, in the case where the side folds are provided on both the accommodation side and the lid side of the base body, the base end portion is provided on the peripheral portion of the accommodation side of the sheet-shaped base body. Attach the lateral gullet so that is facing outward,
The peripheral edge portion of the base side of the base is such that the side gusset body is attached so that the base end portion faces inward.

Only the standing position of the body will be slightly inward. Further, when the width of the joined body is set to be substantially equal to the width of the base end portion of the side body to be welded, bending work of the joined body at the corner peripheral portion is facilitated, and the covering of the peripheral portion of the base body is covered. It will be possible to do so continuously. Moreover, it does not hinder the welding of the lateral gill.
