Abstract: A layered structure for a paper box includes an inner box, an outer cover and a carrying plate. The inner box is formed with a first opening, and a stepped surface is formed at the inner edge of the first opening. The outer periphery of the carrying plate is formed with a flange, and the carrying plate is disposed in the first opening and the flange thereof is supported by the stepped surface. The outer cover is formed with a second opening, the second opening is sleeved with the first opening, and the outer cover is served to cover the first opening and cover outer sides of the inner box. Because the stepped surface is integrally formed in the inner box, the manufacture procedure of the layered structure for a paper box can be simplified thereby reducing material stock and lowering production cost.
