<p>PROBLEM TO BE SOLVED: To minimize the deformation of a packaging case and prevent damages generated by impact. SOLUTION: An opening 9 is formed on one folding-back flap 7 of a packaging case 5, while a protruded section 10 is formed on the corresponding folding back flap 8. At the time of assembling the packaging case, the protruded section 10 is inserted into the opening 9 and folded back in the direction of the folding- back flap 8 to form a mesh structure. When the storage matter is moved inside the packaging case by the dropping of packaging case or the like and the impact is applied from the inside of the packaging case toward the side face in the packaging case, the impact is absorbed by the mesh structure of the opening 9 with the protruded section 10 to reduce the load applied to the ridge faces of the packaging case. The deformation of the packaging case, therefore, is minimized to prevent damages generated by the impact.</p> |
