2. Description of the Related Art Bags made of a thermoplastic polymer film, which are usually made of a thermoplastic polymer film, are used for taking out contents such as water-containing contents, fresh foods such as fresh fish and vegetables, and rice for sale in supermarkets and retail stores. A bag with a handle without a means for closing the part is used. Therefore, when packaging water-containing contents or fresh food products such as fresh fish and vegetables,
Such a bag is separately placed in an upper bag which is sealed with a bag or sheet made of a polymer film or the like.

For example, when selling a small amount of rice or the like in a convenience store or the like, it is put in a sealed type bag which is sealed on all four sides, and when carrying it out, a bag body with a separate carrying handle is used. It was a bag to put home the rice in a bag.

[0004]

In this case, as a bag having a handle made of a thermoplastic polymer film, a bag having no blocking means has been widely used from the prior art.
In the case of a product containing moisture or a product that needs to be sealed for hygiene, a sealed container or bag is required in addition to the take-out bag. Also, when selling small quantities of rice, it was customary to put the sealed bag at the time of sale in a separate carrying bag and carry it around.

[0005] As described above, conventionally, two kinds of bags are required separately for the packaging bag and the take-out bag body for displaying products, and the cost is too much, and the labor at the time of sale is too great. It was such a thing. In addition, for bags for sale, after opening the product after sale, it was necessary to put it in a separate storage bag such as a sealed container or a storage tapper in order to maintain a good storage condition. .

[0006] In particular, when selling small quantities of rice, etc., it is necessary to open the bag at the time of sale and then transfer the remaining rice separately to a rice bowl or the like, especially for single persons who use convenience stores or the like. It takes time for a small family,
Some kind of solution was required to keep good preservation.

Are those that have. Further, a stacking portion 7 is provided in the opening direction of the bag body 1 in order to enhance the strength of the bag body, and the stacking portion 7 is provided with a hole forming a carrying portion 8. In this case, the polymerized portion 7 is not limited to the one formed by fusing or adhering the thermoplastic polymer film, but includes the one having the polymerized portion formed by another member such as paper or metal. Further, the carrying part 8 is not limited to one having a hole, and the carrying part may be composed of a separate member, such as a string, tape, or synthetic resin.

Next, an articulation tape 4 having a male member 3 is fused or adhered to one opening of the thermoplastic polymer film 1a constituting the bag 1 inside the bag 1.
When the base of the articulation tape 4 having the male member 3 constituting the occlusal portion is fused with the bag body 1, it is preferably made of polyethylene, polypropylene or a copolymer thereof. Further, the male member 3 constituting this occlusal part is not limited to the case where it is integrally molded with the base of the articulating tape 4, and the male member 3 is fused or adhered to the base of the articulating tape 4. Good. In this case, it is most preferable that the base of the articulation tape 4 and the male member 3 are made of the same member,
Even if another member is used, it may be one that can maintain the fused state or the adhered state.

Next, an articulation tape 6 having a female member 5 is fused or adhered to another thermoplastic polymer film 1b constituting the bag 1 in the direction of the opening inside the bag 1. An articulating tape 6 having a female member 5 that constitutes this occlusal portion
