<p>PROBLEM TO BE SOLVED: To provide the structure for a packing box which can selectively form either a maximum interior space or a reduced interior space smaller than the maximum interior space in a single packing box according to the size of the article to be stored. SOLUTION: This structure for the packing box which can form a maximum interior space 17a with a front surface wall 2, a back surface wall 3, a right side wall 4, a left side wall 5, a top wall 6, and a bottom wall 7 is provided with a partition wall 8 formed on the front surface wall 2 by means of a crease line 8a and a shoulder portion 9 having an abutment surface 9a and a supporting surface 9b formed on the back surface wall 3 and the bottom wall 7 by means of a pair of crease lines 9c and a pair of cuts 9d. The abutment surface 9a and the supporting surface 9b are folded back and the abutment surface 9a abuts on the partition wall 8 bent along the crease line 8a to form a reduced interior space 17b smaller than the maximum interior space 17a in a packing box 1.</p> |
