[0005]
However, in the conventional example 2, the sealing paper is made of a thick paperboard that is integral with the box and the lid, and requires a strong tearing force for the removal operation of the sealing paper, so that the removal of the sealing paper is poor. In addition, perforations for excision at the time of use are provided on both sides of the sealing paper, and the moisture permeation preventing property is low. In addition, when the sealing paper is removed along the perforation, both sides of the sealing paper remain at the opening of the box from which the sealing paper has been removed, and the entire surface of the opening cannot be opened, so the contents can be taken out from the box. Is bad.
[0006]
Further, in the prior art 2, the end portion of the sealing paper extending from one of the two sides sandwiching the opening of the box to the other lid connecting portion side is folded, and the lid is covered from above. For this reason, the cover is easy to open due to repulsion of the folded end of the sealing paper, and the folded end of the sealing paper is difficult to adhere to the opening of the box without any gap, and the sealing performance is also poor.
