Abstract: Disclosed is a packaging device. Since a distance from a first top surface of a side plate to a surface of a bottom plate is greater than a distance from a second top surface to the surface of the bottom plate, that is, a top surface of the side plate of a box body is designed into an outer convex and inner concave structure, through subsequent reasonable design of sizes of the first top surface, the second top surface and a first slope surface and an angle of the first slope surface, when a box cover and the box body match, the box body and the box cover can match more closely.
