Packing structure

Abstract

A packing structure including a board is provided. The board includes a plurality of pre-bending portions. The board is divided into a plurality of parts by the pre-bending portions, and two adjacent parts are adapted to bend relatively by the corresponding pre-bending portion. At least one of the pre-bending portions includes two pre-bending line, and a distance between the two pre-bending line is equal to a thickness of the board.

1 . A packing structure, comprising:
 a board, comprising a plurality of pre-bending portions, wherein the pre-bending portions divide the board into a plurality of parts, two adjacent of the parts are adapted to bend relatively by the corresponding one of the pre-bending portions, at least one of the pre-bending portions comprises two pre-bending lines, the two pre-bending lines are two grooves, and a distance between the pre-bending lines is equal to a thickness of the board.   
     
     
         2 . (canceled) 
     
     
         3 . The packing structure as claimed in  claim 1 , wherein the pre-bending portions comprise a first pre-bending portion, a second pre-bending portion, and a third pre-bending portion, the parts comprise a first part, a second part, a third part, and a fourth part, the first pre-bending portion connecting between the first part and the second part, the second pre-bending portion connecting between the second part and the third part, and the third pre-bending portion connecting between the third part and the fourth part. 
     
     
         4 . The packing structure as claimed in  claim 3 , wherein the first part is fixed to the fourth part, such that the parts are adapted to form a containing space, and the board is adapted to be bent into a pressed condition by using the pre-bending portions. 
     
     
         5 . The packing structure as claimed in  claim 4 , wherein the first pre-bending portion comprises the two pre-bending lines, and when the board is in the pressed condition, the first part and the second part bend relatively by using the two pre-bending lines, such that the first part leans against the second part. 
     
     
         6 . The packing structure as claimed in  claim 4 , wherein the third pre-bending portion comprises the two pre-bending lines, and when the board is in the pressed condition, the third part and the fourth part bend relatively by using the two pre-bending lines, such that the third part leans against the fourth part.
