Packing box

Abstract

A packing box is composed of a cover and a container, and a ridge connecting the cover and the container. The cover has a cap formed at a top thereof. A first step is formed under the cap and with an upper surface and a wall. Two notches are respectively defined in the cap at two corners to form two pressed portions on the upper surface. A first rim is formed around the first step. Two first triangular portions are respectively formed on the first rim at the corners. The container has a second step corresponding to the first step. A second rim is formed around the second step. Two second triangular portions are respectively formed on the second rim and corresponding to the first triangular portions.

What is claimed is:  
     
         1 . A packing box comprising: 
 a cover ( 10 ) having a cap ( 11 ) formed at a top thereof, a first step ( 13 ) formed under the cap ( 11 ) and with an upper surface ( 131 ) and a wall ( 132 ) perpendicular to the upper surface ( 131 ), two notches ( 12 ) respectively defined in the cap ( 11 ) at two corners to form two pressed portions ( 14 ) on the upper surface ( 131 ), a first rim ( 16 ) formed around the first step ( 13 ), and two first triangular portions ( 17 ) respectively formed on the first rim ( 16 ) at the corners;    a container ( 20 ) integrated with the cover ( 10 ), the container ( 20 ) having a second step ( 21 ) formed thereon and corresponding to the first step ( 13 ), a second rim ( 24 ) formed around the second step ( 21 ), and two second triangular portions ( 25 ) respectively formed on the second rim ( 24 ) and corresponding to the first triangular portions ( 17 ); and    a ridge ( 30 ) formed between the cover ( 10 ) and the container ( 20 ) to connect the cover ( 10 ) and the container ( 20 ) together, and opposite to the triangular portions ( 17 ,  25 ).    
     
     
         2 . The packing box as claimed in  claim 1 , wherein the cover ( 10 ) further has two stops ( 15 ) respectively formed on the first step ( 11 ) at the corners and protruded inwards on the wall ( 132 ), and the container ( 20 ) has two recesses ( 23 ) respectively defined in the second step ( 22 ) at the corners for receiving the corresponding stop ( 15 ) therein, each recess ( 23 ) having an upper edge ( 22 ) for preventing the stop ( 15 ) from easily escaping from the recess ( 23 ).  
     
     
         3 . The packing box as claimed in  claim 1 , wherein the container ( 20 ) further has two lugs ( 26 ) respectively formed on an upper surface of the second triangular portions ( 25 ).  
     
     
         4 . The packing box as claimed in  claim 3 , wherein the lugs ( 26 ) are semi-spherical.  
     
     
         5 . The packing box as claimed in  claim 1  further comprising two bent edges ( 171 ) formed between the first rim ( 16 ) and the first triangular portions ( 17 ).  
     
     
         6 . The packing box as claimed in  claim 1  further comprising patterns formed on the first triangular portions ( 17 ).  
     
     
         7 . The packing box as claimed in  claim 1  further comprising patterns formed on the second triangular portions ( 25 ).
