2. Description of the Related Art General cake boxes are roughly classified into those made of polystyrene foam or paper. Among them, the one made of polystyrene foam is formed by integrally foaming a foamed material, and a cake whose outer periphery is circular is fitted over the bottom seat of the bottom seat having a concave portion to store the cake. This kind of cake box has a vertical inner wall of the bottom seat, and when storing a large cake, it has to be carefully held horizontally so as not to break the decoration on the side of the cake. In addition, since the bottom seat and the top lid cannot be stacked and stored, it is inconvenient to store and transport. In addition, it does not spoil and melt naturally after disposal, causing environmental and ecological damage.

[0003] Further, a general paper cake box is formed by cutting a paperboard having an appropriate thickness in accordance with the shapes of a bottom seat and a lid, folding each of them, and laminating an overlapping portion. These paper cake boxes also have a drawback that, similarly to the above-mentioned polystyrene foam cake box, the bottom seat and the top lid cannot be stacked and stored.
