And a lid body (52) which is fitted into the box body and is formed to have a relatively larger depth than the box body (51), and a pair of opposing side walls (57) (57) of the lid body in the height direction. Box body corresponding to (51)
There is a known packaging paper box provided with step portions (61) (61) that come into contact with the upper edges of the side walls (53) (53) of the.

In this packaging paper box, when the box body (51) is fitted into the lid body (52) with the top and bottom reversed, the box body (51) is supported by the steps (61) and (61). By this, the box body (51)
A state in which is lifted, that is, a so-called raised bottom state is realized. Further, since the box body (51) is originally formed to be relatively shallower than the article to be packaged (A), when the article to be packaged (A) is housed in the box body (51) in the raised bottom state, Since the object to be packaged (A) is easy to see and exhibits an excellent display effect, this packaging paper box is often used for packaging products for gifts.

Thus, the lid (52) of this packaging paper box has the stepped portion (61) from the middle portion in the height direction of the inner side walls (57a) (57a) of the pair of opposing side walls (57) (57). The stepped support piece (62) and the sticking piece (63) are successively connected through the folds (64) (65) (66), respectively, and the sticking piece (63) is attached to the lid (52).

The step support piece (62) and the side wall (57) are placed in parallel with each other, and the other required parts are bent, raised, and engaged to manufacture and assemble them.

However, the fold (65) between the step (61) and the step support piece (62) is a mountain fold while the other folds (64) (66) are valley folds. Since the length of this mountain fold (65) is equal to the length of the fold between the top plate (77) and the side wall (57), the torque for raising the side wall (57). It is hard to act on this mountain fold (65), and it may be difficult to assemble as it is. Especially, the thicker the paper box is, the more remarkable the tendency is.

Therefore, the mountain folds (65) must be preliminarily provided with so-called folds or bent by using a jig, resulting in extra production time and production cost.

Of course, it is also known that the torque for raising the side wall (57) effectively acts on the mountain fold (65) if the length of the step portion is shortened, but the shorter the step portion, the more When the packaging paper boxes containing the packages are stacked in multiple stages, the load per unit area applied to the steps increases, and the steps may be crushed and the desired box shape may be impaired. is there.
