Description

The present invention relates to a packaging box and a blank thereof.

A packaging box made of corrugated cardboard or the like is often used for transporting cargo, for example, for shipping a product from a product manufacturer to a retail store. In many cases, when a product arrives at a store, the store needs to open the packaging box and line up the product at the store. Therefore, packaging boxes are required to be easy to open and easy to take out products.

In order to facilitate the opening work of the packaging box, Cited Document 1 discloses that the opening portion is separated to partially release the fixing of the top surface and lift the top surface to open the package. However, in the method involving the separation of the opened portion in this way, scraps are generated at the time of opening, and a new problem of processing thereof arises. Further, at the time of opening, a two-step operation of disconnecting the opened portion and subsequently lifting the top surface is required.
