The number of labels 8 may be one, two or more, and the number may be set according to the type of display.

The label 8 may be attached manually by an operator, but if it is attached mechanically using a labeling machine or the like, the production efficiency will be further improved.

In the rice ball 10 according to this embodiment configured as described above, it is not necessary to use a packaging body labeled according to the type of contents of the rice for rice 11 and one packaging body 1 is used. Since it can handle several types of contents, it is not necessary to stock several types of packaging as in the past, and the labor required for management can be reduced, and one type of packaging can be used continuously, Even if the value changes, it is not necessary to change the process and the productivity can be greatly improved. In the above description, the label 8 indicating the type of contents of the rice 11 for holding rice is attached to the surface side of the exterior film 2 of the package 1, but the common portion (for example, the design portion) Needless to say, the printing may be performed by printing such as gravure printing as in the conventional case.

Next, the procedure for opening the package of the rice ball 10 constructed as described above will be described. First, when the end portion of the unsealing tape 4 is grasped and pulled by hand and the unsealing tape 4 is removed from the packaging body 1, the exterior film 2 is divided into left and right parts. Here, when the left half of the package 1 is pulled to the left and the right half is pulled to the right, a portion of the rice 11 for rice balls is filled with seaweed 6
The contents are exposed in a state of being wrapped around, and then the seaweed 6 is pressed against the surface of the rice for rice 11.

In this case, a plurality of notches 13, 13 ..., 8a, 8a ... Are provided in the portion of the packaging body and the portion of the label 8 located on the path of the unsealing tape 4 and the packaging is performed. Since the body 1 is provided with the cutouts 9, 9, 9, 9 for allowing the opening tape 4 to escape, the resistance acting on the opening tape 4 can be significantly reduced.

Therefore, the unsealing tape 4 will not be broken in the middle, and the unsealing tape 4 can be surely removed from the package 1, so that the unsealing of the package 1 can be surely performed.

In this embodiment, the case where the package 1 is used for the rice ball 10 has been described.
Needless to say, the packaging body 1 described above may be used for packaging other foods such as hamburger steak, buns, etc. Further, as described above, if a uniaxially or biaxially stretched synthetic resin film is used for the exterior film 2, the unsealing means can be formed without using the unsealing tape 4.
