Description

  The present invention relates to a packaging paper box, in particular, each of the four side walls of the box body has an inner / outer double wall portion and an upper wall portion connected to the double wall portion, while the side wall of the lid that covers the box body. The present invention relates to a wrapping paper box having a step portion that abuts on the upper wall portion at an intermediate height position.

  The so-called frame-type wrapping paper box, in which the box body has each of the four side walls, an inner and outer double wall part and an upper wall part connected to the double wall part, gives a strong impression and is actually resistant. Because of its excellent loadability, for example, it is often used as a packaging paper box for gifts, such as whiskey, brandy, wine, etc., for the packaging of relatively heavy and expensive products.

  In addition, such a wrapping paper box is used to display merchandise at stores such as liquor stores, after removing the lid from the box body and then placing the box body with the merchandise stored in the upside down. Sometimes used. This is because the stepped portion of the lid body looks like the box body is raised and lifted, and the appearance of the product is also improved.

  However, the lid step is not originally designed to receive the load of the product, so if it is used as described above, the lid step will not withstand the load of the product and will collapse. There was a case.

  Naturally, such a problem can be solved by increasing the paper thickness of the lid, but this increases the material cost and makes it difficult to perform the assembly operation from the unfolded state to the box form.

Further, as disclosed in Japanese Utility Model Laid-Open No. 58-192222, a reinforcing piece that is obliquely passed from the inner wall portion of one side wall to the adjacent side wall is provided, and the reinforcing piece is also provided from the adjacent side wall. A paper box having a reinforcing piece that is obliquely passed to the side wall is also known, but it has been found that the paper box is somewhat troublesome to assemble.
