In this state, the end face of the laminated sheet 6 peeled from the laminated sheet 5 is pinched with a finger and the laminated sheet 6 is pulled to the other joint 7b side, whereby a portion of the laminated sheet 6 having an appropriate width is cut off and stored. Although the opening 9 is formed in the bag 1, the opening 9 may be similarly formed in the storage bag 1 by turning over the laminated sheet 5 of the other non-joined portion 8 b. Further, the portion of the laminated sheet 6 having an appropriate width which has been cut as described above can be removed from the laminated sheet 5.

Next, a second embodiment shown in FIGS. 7 to 9 will be described. The difference from the first embodiment is that in the first embodiment, the other joint portion 7b side has one side. As in the case of the joining portion 7a, the non-joining portion 8b is provided between the joining sheets 7b and the end face of the laminated sheet 5 and between the two laminated sheets 5 and 6, whereas in the second embodiment, the other is not joined. The non-joined portion 8b is not present on the joined portion 7b side. Further, in the second embodiment, the end face of the laminated sheet 5 on the side of the other bonding portion 7b where the non-bonding portion 8b does not exist is scratched to such an extent that it cannot be recognized by the naked eye. Other configurations are the same as those of the first embodiment.

Therefore, in the second embodiment,
When taking out the contents from the storage bag 1, the laminated sheet 5 of one non-joined portion 8a is turned over, and one joined portion 7a is peeled off from the laminated sheet 5; The end face is pinched with a finger and the other joint portion 7b
By pulling the laminated sheet 6 to the side, the part of the laminated sheet 6 having an appropriate width is cut off and the storage bag 1 is opened as in the first embodiment, but in the second embodiment, When the end face of the laminated sheet 6 peeled from the laminated sheet 5 is pinched by a finger and the laminated sheet 6 is pulled to the other joint 7b side and cut off, there is no non-joined part on the other joint part 7b side and the other Since the end face of the laminated sheet 5 on the side of the joint 7b is so scratched that it cannot be discerned by the naked eye, the joint 7b is also torn, and the tearing is stopped at the position of the heat-sealed outer fold 2a. . That is, the maximum tearing range is up to the heat-sealed outer fold 2a, and an opening 9 larger than that of the first embodiment is formed in the storage bag 1.

Next, a third embodiment shown in FIGS. 10 to 12 will be described. The difference from the second embodiment is that the length of the storage bag 1 in the second embodiment is While two outer folds 2a, 2a on each side along the two sides are fused by heat sealing, in the third embodiment, two folds on each side along the length direction of the storage bag 1 are provided.

Pulling the laminated sheet 6 to the side cuts a part of the laminated sheet 6 having an appropriate width and opens the storage bag 1 in the same manner as in the first and second embodiments.
In the third embodiment, when the end face of the laminated sheet 6 peeled off from the laminated sheet 5 is pinched by a finger and the laminated sheet 6 is pulled to the other joint portion 7b side and cut off, the other joint portion 7b side is not cut off. No joint exists and the other joint 7
Since the end face of the laminated sheet 5 on the b side is so scratched as to be indistinguishable to the naked eye, the joint 7b is also cut off,
Further, since the outer fold 2a is not heat-sealed, the fold 2a can be further torn without stopping at the position of the outer fold 2a. That is, the maximum tearing range can be further extended than the position of the outer fold line 2a, and the opening 9 larger than the first and second embodiments is formed in the storage bag 1.

By the way, in the above embodiment,
Although the laminated sheet 6 constituting the widthwise central portion 3 on the front side of the storage bag 1 is joined to the laminated sheet 5 constituting the other portion 4 by heat sealing so as to be easily delaminated so as to have easy-openability. In addition to the delamination, it is also possible to configure such that interfacial delamination or cohesive delamination becomes possible. In addition, the joining width of the two laminated sheets 5 and 6 is set to about 7 mm, and the width may be appropriately determined according to the size of the storage bag 1 or the like. Further, the laminated sheet 6 constituting the widthwise central portion 3 on the front side of the storage bag 1 is joined to the laminated sheet 5 constituting the other portion 4 by heat sealing so as to be easily delaminated so as to have easy-openability. However, a similar configuration may be provided on the back side of the storage bag 1. In addition, storage bag 1
Is not limited to the gusset shape, and may be a general shape without V-shaped folds on both sides. Furthermore, the contents stored in the storage bag 1 are not limited to miso, but may be other foods such as confectionery or other foods. Further, the laminated sheet 6 is provided at the widthwise central portion 3 on the front side or the back side of the storage bag 1, but the disposition position of the laminated sheet 6 is not limited to the widthwise central portion 3 of the storage bag 1. Alternatively, the position may be shifted to one side in the width direction of the storage bag 1. Further, as the material of the laminated sheet 5 and the laminated sheet 6 constituting the storage bag 1, a laminated sheet formed by laminating a plurality of synthetic resin films is used as a material, but the present invention is not limited to this. Instead, for example, in order to give the storage bag 1 a barrier property, a material obtained by laminating an aluminum foil on a synthetic resin film or laminating a synthetic resin film on which aluminum is deposited may be used.
