Packing box

Abstract

A packing box is provided. The packing box includes a cover, a box body, a connecting plate, and a lining partition. The connecting plate is connected between the cover and the box body through bending, so that the cover is adapted to rotate relative to the box body to open and close. The lining partition is disposed in the box body and is folded to form a main space of a step structure. The step structure is configured to hold an object. A lower surface of the step structure and an inner surface of the box body jointly form an accommodation space for accommodating another object.

What is claimed is: 
     
         1 . A packing box, comprising:
 a cover;   a box body;   a connecting plate, connected between the cover and the box body through bending, so that the cover is adapted to rotate relative to the box body to open and close; and   a first lining partition, disposed in the box body and folded to form a main space of a step structure, wherein a lower surface of the step structure and an inner surface of the box body jointly form a first accommodation space.   
     
     
         2 . The packing box according to  claim 1 , wherein the first lining partition comprises a plurality of first lining partitions respectively disposed on opposite sides of the box body. 
     
     
         3 . The packing box according to  claim 1 , wherein the first lining partition is integrally formed and folded. 
     
     
         4 . The packing box according to  claim 1 , wherein the step structure comprises a top surface and a step platform surface lower than the top surface. 
     
     
         5 . The packing box according to  claim 4 , wherein when viewed from a direction of a top view, the first accommodation space overlaps with the step platform surface. 
     
     
         6 . The packing box according to  claim 4 , further comprising a second lining partition, disposed in the box body, and folded to form a second accommodation space together with the inner surface of the box body, wherein a top surface of the second lining partition is lower than the step platform surface or coplanar with the step platform surface. 
     
     
         7 . The packing box according to  claim 6 , wherein an object is placed on the step platform surface and the top surface of the second lining partition. 
     
     
         8 . The packing box according to  claim 1 , wherein the box body comprises a box body protection slope that is connected between two adjacent side surfaces of the box body and an obtuse angle is included between the two adjacent side surfaces of the box body respectively, and the cover comprises a cover protection slope that corresponds to the box body protection slope, that is connected between two adjacent side surfaces of the cover, and an obtuse angle is included between the two adjacent side surfaces of the cover respectively. 
     
     
         9 . The packing box according to  claim 1 , wherein the cover further comprises a top protection slope that is connected between a top surface of the cover and a corresponding side surface and an obtuse angle is included between the top surface of the cover and the corresponding side surface respectively. 
     
     
         10 . The packing box according to  claim 9 , wherein the first lining partition comprises a slope corresponding to the top protection slope, and an obtuse angle is included between the slope and a top surface of the first lining partition.
