Abstract

A packaging box comprising a box and a frame disposed inside the box is provided. The frame includes a bottom panel, two flaps and two tabs. The flaps are connected to the opposite sides of the bottom panel and the junction between each flap and the bottom panel has a first folding line. Each flap includes a plurality of inlaid openings, a second folding line and a third folding line. The inlaid openings are arranged along the direction of extension of the first folding line. The second folding line is tangent to one side of these inlaid openings. The third folding line is tangent to the opposite side of these inlaid openings. The distance from the bottom panel to the second folding line is greater than that to the third folding line. The tabs fixed to the bottom panel are connected to the flaps along the respective second folding lines.
