Packing box having dish structure

Abstract

Disclosed herein is a packing box having a dish structure and, more particularly, a packing box having a dish structure allowing the box to be deformed for use as a dish. The packing box includes a polygonal bottom portion ( 100 ), a sidewall portion ( 200 ) extending from an edge of the bottom portion ( 100 ) to form a wall member on the bottom portion ( 100 ), a wing portion ( 300 ) extending from the sidewall portion ( 200 ) to connect corners of the sidewall portion ( 200 ) such that the sidewall portion ( 200 ) takes a form unfolded outward on the bottom portion ( 100 ), and a fixing portion ( 400 ) formed at the wing portion ( 300 ) and the sidewall portion ( 200 ) to allow the wing portion ( 300 ) and the sidewall portion ( 200 ) to be fastened to each other such that the sidewall portion ( 200 ) is fixed by being unfolded outward on the bottom portion ( 100 ).

What is claimed is: 
     
         1 . A packing box having a dish structure comprising:
 a polygonal bottom portion ( 100 );   a sidewall portion ( 200 ) extending from an edge of the bottom portion ( 100 ) to form a wall member on the bottom portion ( 100 );   a wing portion ( 300 ) extending from the sidewall portion ( 200 ) to connect corners of the sidewall portion ( 200 ) such that the sidewall portion ( 200 ) takes a form unfolded outward on the bottom portion ( 100 ); and   a fixing portion ( 400 ) formed at the wing portion ( 300 ) and the sidewall portion ( 200 ) to allow the wing portion ( 300 ) and the sidewall portion ( 200 ) to be fastened to each other such that the sidewall portion ( 200 ) is fixed by being unfolded outward on the bottom portion ( 100 ),   wherein the fixing portion ( 400 ) comprises:   a fixing segment ( 410 ) formed at the wing portion ( 300 ); and   a fixing groove ( 420 ) formed at the sidewall portion ( 200 ) by perforation to allow the fixing segment ( 410 ) to be fixed when introduced into the fixing groove ( 420 ).   
     
     
         2 . The packing box according to  claim 1 , wherein the sidewall portion ( 200 ) comprises:
 first sidewalls ( 210  and  210 ′) extending from opposing sides of the bottom portion ( 100 ) and facing each other to form sidewalls on the bottom portion ( 100 ) when folded up; and   second sidewalls ( 220  and  220 ′) extending from other opposing sides of the bottom portion ( 100 ) and facing each other to form other sidewalls on the bottom portion ( 100 ).   
     
     
         3 . The packing box according to  claim 2 , wherein the first sidewalls ( 210  and  210 ′) comprise:
 inner sidewalls ( 212  and  212 ′) extending from the bottom portion ( 100 ) and facing each other to form an inner wall member on the bottom portion ( 100 ); 
 outer sidewalls ( 214  and  214 ′) extending from the inner sidewalls ( 212  and  212 ′) to form an outer wall member on the bottom portion ( 100 ); and 
 fixing surfaces ( 216  and  216 ′) extending from the outer sidewalls ( 214  and  214 ′) and fixed to the lower surface of the bottom portion ( 100 ). 
 
     
     
         4 . The packing box according to  claim 2 , wherein the wing portion ( 300 ) extends from the second sidewalls ( 220  and  220 ′) and is formed between the corners of the first sidewalls ( 210  and  210 ′) and the second sidewalls ( 220  and  220 ′) such that the wing portion ( 300 ) is inserted into or withdrawn from a space formed by folding the first sidewalls ( 210  and  210 ′) in an overlapping manner. 
     
     
         5 . The packing box according to  claim 2 , wherein the wing portion ( 300 ) comprises:
 a moving surface ( 310 ) extending in a fan shape from the second sidewalls ( 220  and  220 ′) and moving inside the first sidewalls ( 210  and  210 ′); and   a fold surface  320  extending from the moving surface ( 310 ) and folded inward of the moving surface ( 310 ).   
     
     
         6 . The packing box according to  claim 1 , wherein the fixing segment ( 410 ) is coupled to the fixing groove ( 420 ) such that the wing portion ( 300 ) is fixed after being partially withdrawn from an inner space formed by folding the sidewall portion ( 200 ). 
     
     
         7 . The packing box according to  claim 1 , wherein the bottom portion ( 100 ) has a shape selected from among a triangle, quadrangle, pentagon, hexagon, and octagon. 
     
     
         8 . The packing box according to  claim 2 , wherein the wing portion ( 300 ) comprises:
 a moving surface ( 310 ) extending in a fan shape from the second sidewalls ( 220  and  220 ′) and moving inside the first sidewalls ( 210  and  210 ′); and   a cutoff surface ( 330 ) extending from the second sidewalls ( 220  and  220 ′) and cut off from the moving surface ( 310 ) to be fastened to the first sidewalls ( 210  and  210 ′).   
     
     
         9 . The packing box according to  claim 8 , wherein the fixing portion ( 400 ) comprises:
 a fastening segment ( 430 ) extending from the cutoff surface ( 330 ); and   a fastening groove ( 440 ) formed at the first sidewalls ( 210  and  210 ′) by perforation to allow the fastening segment ( 430 ) to be fixed when introduced into the fastening groove ( 440 ).   
     
     
         10 . The packing box according to  claim 1 , wherein the sidewall portion ( 200 ) extends from each side of the bottom portion ( 100 ) and forms sidewalls on the bottom portion ( 100 ) by being folded at least once.
