PACKAGING STRUCTURE FOR ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a packaging structure for an article wherein the strength of an inner box for cushioning to be put into an outer box is improved by forming a circumferential wall having a channel-shaped cross section so as to surround the periphery of a window hole. SOLUTION: In the packaging structure, at a window hole forming location, an inner side position limiting piece 6 which extends inwardly from a window hole frame 3a forming the edge of a window hole 3 by a distance nearly equal to the length of an outer side position limiting piece 5 and which is separated at four corners thereof and can be bent in the same direction as the piece 5 is provided. The piece 5 and the piece 6 are restricted by a restriction means and a top surface formed between a bent side and the frame 3a forms a circumferential wall having a U shape together with the pieces 5, 6, thereby surrounding the hole 3 to improve the strength of an inner box for cushioning.
