[Effect of device]

 As described above, according to the present invention, a pair of front and back films extend outward from the central portion on the top side of the storage part formed by expanding to form a tongue piece for opening. On the inner side surface of the tongue piece of the bag body, a chuck of male and female claws is provided which is parallel to the longitudinal side surface of the top side at a distance from the central part, and the chuck and its adjacent thick part are attached to the top side. The width from the corner to the center is P, the height from the center to the top of the chuck and its adjacent thick part is Q, and the height from the center to the chuck and the bottom of the adjacent thick part. When R, the configuration satisfies the dimensional relationship of P> Q or P <R. Therefore, when the tongue is bent along the accommodating part, the chuck and the thick part around it are box-shaped accommodating. It is possible to fold without avoiding the corners, or fold the thick part adjacent to the chuck. Since a guide recess is provided at the required bending position to facilitate bending, a zipper is used when the bag body containing the product in a box-shaped storage unit is packed in a corrugated cardboard box for shipping or displayed at the store for sale. Since the tongue for opening the opening has no obstruction, it can be compactly stored or displayed in the store, and the tongue is located in the center of the top gusset part of the box-shaped storage. Therefore, when the tongue is provided with a levee hole or a levee string is attached for carrying, the weight of the bag is concentrated on the tongue in the central portion, which is advantageous in that it can be held in a well-balanced manner.
