Therefore, when the synthetic resin film forming the bag portion 1 and the opening / closing piece 4 is transparent, striped patterns or spots are formed at the bonding portion between the bag portion 1 and the opening / closing piece 4 via the adhesive portion 5. Patterns often appear and are unsightly. On the other hand, as described above, it was troublesome to carry out the series of steps of putting the product in the bag portion 1 of the bag body A and closing the opening 14 of the bag portion 1 with the opening / closing piece 4, so the working procedure is a little further. There was also a desire to simplify it.

The present invention has been made in view of the above circumstances. By devising the place where the adhesive portion is formed and the place where the opening / closing piece is provided, a striped pattern or a stripe pattern is formed at the joining portion between the opening / closing piece and the adhesive portion. It is an object of the present invention to provide a bag body in which even if a mottled pattern appears, it does not make the bonded portion unsightly. Further, according to the present invention, when the product is put in the bag portion, it is not necessary to fold the opening / closing piece to expose the opening of the bag portion at the initial stage, and the bag portion containing the product can be removed. An object of the present invention is to provide a bag body that simplifies an example work procedure until the opening is closed with an opening / closing piece.

[0008]

[Means for Solving the Problems]

 That is, in order to solve the above problems, the bag body is made of a synthetic resin film, and the extending piece portion provided at a part of the rim of the opening of the bag portion is folded in two to extend The exit edge is joined to the base of the extension piece in front of the opening, and the paper core is sandwiched between the two folds of the extension piece. In the remaining part, an opening / closing piece that can be folded back is extended between an open state in which it is overlaid on the outside of the bag part and a closed state in which the paper core is sandwiched between two folded parts of the extending piece part. It is characterized in that the opening / closing piece is provided with an adhesive portion on the overlapping surface with the folded portion of the extending piece portion.

Alternatively, the bag body is characterized in that it has a peeling piece that can be attached to and detached from an adhesive portion provided in the opening / closing piece.

[0010]

[Action]

 In the bag body of the means of (1), the opening / closing piece is extended to the rest of the opening edge of the bag portion not provided with the extending piece portion, and the adhesive portion provided on the opening / closing piece has the paper core sandwiched. Since it is designed to be attached to the folded part of the extending piece that has been inserted, the opening and closing piece is folded back so as to cover the opening of the bag part, and the adhesive part of the opening piece When the opening / closing piece is attached to the folded portion, the portion where the opening / closing piece and the extension portion are attached via the adhesive portion overlaps the paper core sandwiched in the extension portion. Therefore, even if the opening / closing piece and the synthetic resin film forming the above-mentioned extending portion are transparent, the stripe pattern or spot pattern appearing at the bonding location becomes almost invisible to the eye. Even if the adhesive part is dirty, it becomes almost invisible to the naked eye.

On the other hand, when the opening / closing piece is in an open state in which the opening / closing piece is placed outside the bag, the opening of the bag is exposed. Therefore, if the opening / closing piece is set to open when the bag is not in use, the opening / closing piece is folded back at the first stage when putting the product in the bag, and the opening of the bag is brought out. You don't have to do troublesome work, and you can immediately open the bag opening and put in the product.

According to the bag body of the means, the peeling piece can be adhered to the adhesive part provided on the opening / closing piece until the opening / closing piece of the bag part is closed by the opening / closing piece. This keeps the adhesive part from becoming dirty while the product is being put into the bag.
