[0003] The prior art discloses a packaging box with an automatic unfolding structure, which is disclosed as CN217049695U. When storing large items and scattered items, it is possible to avoid the difficulty in taking out the items from the top. During the process of opening the movable top box, the side baffles of the paper box on both sides are synchronously opened, so that the items can be taken out from the side, reducing labor and operation difficulty, and improving the efficiency of taking out and storing items. At the same time, during the process of closing the movable top box, the side baffles of the paper box are synchronously closed to complete the packaging of the items. The packaging is convenient and quick, and the structure is simple and easy to use.

[0004] However, although the packaging box can be automatically unfolded to facilitate the storage of the packaged items, the packaging box is still in a box body state after being unfolded, which results in occupying space during the transportation of the packaging box and affects the transportation efficiency of the packaging box. Therefore, a packaging box that is easy to fold and unfold is proposed to solve the above problem. Utility Model Content
