[Prior art]

 In this type of bag, there is a type in which an extended piece integrally provided at an edge of an opening of the bag is folded in two, and a paper core is sandwiched between the two folded portions. And, in the conventional bag body, an opening / closing piece for opening / closing an opening of the bag section is provided on the extension piece side.

Such a conventional bag A is shown in a front view in FIG. 9, and a product is put into the bag A in FIG. 9 and an opening 14 of the bag 1 is closed with an opening / closing piece 4. A series of steps required up to this point are illustratively shown in FIGS.

As shown in FIG. 9 and FIG. 10 which is a cross-sectional view taken along the line NN in FIG. 9, the bag A is formed by folding and welding a flexible synthetic resin film. And is formed in a rectangular shape. More specifically, the above-mentioned film is folded in two at the bottom 11 of the bag portion 1 of the bag body A, and the two films are joined by welding at the left and right edge portions 12 and 13. And, among the lips of the opening 14 of the bag portion 1 through which the product is put in and out, an extension piece 2 is integrally and continuously provided on the back edge, and the extension piece 2 is folded in two. The intermediate portion 21 of the extension piece 2 is welded to the base 22 of the extension piece 2 in front of the opening 14 by welding (welding points are indicated by W). A paper core 3 made of elongated strip-shaped paper is sandwiched between the two folds so as not to move. Further, in the extension piece portion 2, a portion further extending from the welding position W serves as an opening / closing piece 4. An adhesive portion 5 coated with an adhesive is formed in a band shape over the entire width of the front side portion of the bag portion 1 near the opening 14, and is peeled off from the adhesive portion 5 when the bag A is not used. A piece 6 is attached, and the opening / closing piece 4 is placed on the peeling piece 6 and covers the opening 14 of the bag 1. Further, the adhesive portion 5 may be formed between the opening / closing piece 4 and the peeling piece 6 (that is, either the opening / closing piece 4 or the peeling piece 6). Reference numeral 7 denotes a hole opened between the extending piece 2 of the bag 1 and the paper core 3, and this hole 7 is used, for example, when hanging the bag A on a display shelf.

For this reason, when the synthetic resin film forming the bag portion 1 and the opening / closing piece 4 is transparent, a striped pattern or a spot is formed at the bonding portion between the bag portion 2 and the opening / closing piece 4 via the adhesive portion 5. Patterns often appear and become unsightly. On the other hand, as described above, it was troublesome to perform a series of procedures of putting a 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. There was a demand that the system be further simplified.

Further, when taking out the product put in the bag A, the bag A itself is not easily broken due to the use of a durable synthetic resin film, and requires considerable force, especially for children and the elderly. However, there is a problem that recent plastic film bags are difficult to break. Further, there is a demand that the product S taken out of the bag portion at one end be stored in the original bag portion and stored, but a perforation or the like is provided in the bag portion to break the perforation and the bag body after the product S is taken out. Is almost unusable.

The present invention has been made in order to cope with the above circumstances, and by devising a place where an adhesive portion is provided, a stripe pattern or a spot pattern appears at a portion where the opening / closing piece and the adhesive portion are bonded. It is an object of the present invention to provide a bag body that does not make the bonded portion unsightly. In addition, the present invention eliminates the need to fold the opening and closing piece and bring out the opening of the bag at the initial stage when putting the product in the bag, and the opening of the bag containing the product is eliminated. It is an object of the present invention to provide a bag body in which a series of operation procedures until the opening and closing pieces are closed are simplified. Furthermore, the invention of the present application can easily take out the contents with a small force even with a durable synthetic resin film bag, and even if a part of the bag is broken and the product is taken out, it can be used again. The purpose of the present invention is to provide a bag that can be used.
