Packing box and packing method

Abstract

A packing box includes a box main body; and an inner plate on which a packing object is fixed. The inner plate is accommodated in the box main body and is kept in a horizontal direction. The inner plate may include a main plate on which the packing object is fixed, a set of first plates which bendably extend from each of first ends of the main plate opposing to each other, and a set of second plates which bendably extend from each of second ends of the main plate opposing to each other. The packing object is desirably fixed at a center of the main plate such that the packing object is not contact with inner walls of the box main body.

What is claimed is:  
     
         1 . A packing box comprising: 
 a box main body; and    an inner plate on which a packing object is fixed by at least holding band,    wherein said inner plate is accommodated in said box main body and is kept in a horizontal direction.    
     
     
         2 . The packing box according to  claim 1 , wherein said inner plate comprises: 
 a main plate on which the packing object is fixed;    a set of first plates which bendably extend from each of first ends of said main plate opposing to each other; and    a set of second plates which bendably extend from each of second ends of said main plate opposing to each other.    
     
     
         3 . The packing box according to  claim 2 , wherein said packing object is fixed at a center of said main plate such that said packing object is not contact with inner walls of said box main body.  
     
     
         4 . The packing box according to  claim 2 , wherein said first plates are separated by a first gap, and said second plates are separated by a second gap.  
     
     
         5 . The packing box according to  claim 4 , wherein said packing object is wrapped by a first holding band passing through said first gaps between the first plates of each of the sets for said first ends, and 
 said packing object is wrapped by a second holding band passing through said second gaps between the second plates of each of the sets for said second ends.    
     
     
         6 . The packing box according to  claim 2 , wherein said box main body has a rectangular parallelepiped shape, 
 said main plate is rectangular,    said first plates are bent upwardly, and    said second plates are bent downwardly.    
     
     
         7 . The packing box according to  claim 6 , wherein a summation of an extending length of said first plate and an extending length of said second plate is substantially equal to an inner height of said box main body.  
     
     
         8 . The packing box according to  claim 7 , wherein said extending length of said first plate is substantially equal to said extending length of said second plate such that said main plate is held at a middle position in said box main body.  
     
     
         9 . A method of packing a packing object in a packing box, comprising: 
 fixing said packing object on an inner plate;    wherein said inner plate comprises a main plate on which the packing object is fixed, a set of first plates which bendably extend from each of first ends of said main plate opposing to each other, and a set of second plates which bendably extend from each of second ends of said main plate opposing to each other;    bending said first plates upwardly and said second plates downwardly; and    accommodating said inner plate in said box main body to keep said inner plate in a horizontal direction.    
     
     
         10 . The method according to  claim 9 , wherein said fixing comprises: 
 fixing said packing object at a center of said main plate such that said packing object is not contact with inner walls of said box main body.    
     
     
         11 . The method according to  claim 9 , wherein a summation of an extending length of said first plate and an extending length of said second plate is substantially equal to an inner height of said box main body.  
     
     
         12 . The method according to  claim 11 , wherein said extending length of said first plate is substantially equal to said extending length of said second plate such that said main plate is held at a middle position in said box main body.  
     
     
         13 . The method according to  claim 9 , wherein said first plates are separated by a first gap, and said second plates are separated by a second gap, 
 said fixing comprises:    wrapping said packing object by a first holding band passing through said first gaps between the first plates of each of the sets for said first ends; and    wrapping said packing object by a second holding band passing through said second gaps between the second plates of each of the sets for said second ends.    
     
     
         14 . A packing box comprising: 
 a box main body; and    an inner plate which comprises: 
 a main plate on which the packing object is fixed,  
 a set of first plates bent upwardly from each of first ends of said main plate opposing to each other; and  
 a set of second plates bent downwardly from each of second ends of said main plate opposing to each other,  
   wherein said packing object is fixed at a center of said main plate such that said packing object is not contact with inner walls of said box main body.    
     
     
         15 . The packing box according to  claim 14 , wherein said first plates are separated by a first gap, and said second plates are separated by a second gap.  
     
     
         16 . The packing box according to  claim 15 , wherein said packing object is wrapped by a first holding band passing through said first gaps between the first plates of each of the sets for said first ends, and 
 said packing object is wrapped by a second holding band passing through said second gaps between the second plates of each of the sets for said second ends.    
     
     
         17 . The packing box according to  claim 14 , wherein a summation of an extending length of said first plate and an extending length of said second plate is substantially equal to an inner height of said box main body.  
     
     
         18 . The method according to  claim 17 , wherein said extending length of said first plate is substantially equal to said extending length of said second plate such that said main plate is held at a middle position in said box main body.
