Abstract

In the case of a hand hole used for transporting a packaging box, wherein the closing part forming the hand hole part is bent inside the packaging box to form a hand hole, the closing part is returned to an initial state. There is no gap for returning, dust or the like enters the inside of the packaging box from the gap of the closed portion, and the packaged item is soiled. Further, since the closed portion does not return to the initial state, a use mark remains and the appearance is bad.
In a hand hole in which a fold line 1 is provided on the upper side and a tongue-like occlusion part 5 is formed with the other three sides as a cutting part, the tongue-like occlusion part is connected to the lower side cutting part 3 of the hand hole. By providing the two cutting portions 6 and 7 extending outward, the hand hole is designed to be restored to the initial state and to prevent dust and the like from entering, which are the above-mentioned problems.
