<p>PROBLEM TO BE SOLVED: To easily couple integrally and to prevent a corner or the like of a box from being damaged by making side faces of both packaging boxes A, B face each other and inserting a protrusion of the box B into a slit between an upper end rim of one of side rims and an upper lid of the box A. SOLUTION: A packaging box A comprises a single sheet which is cut into a predetermined shape and assembled into a parallelopiped form and includes a back face, a left side face, a front face, a right side face 17, an upper lid 18 and a lower lid which are coupled with one another via creases. Merely by inserting a protrusion 13 of a packaging box B into a slit between an upper end rim 17a of the right side face 17 and the upper lid 18 of the box A, both boxes A, B can be coupled and kept easily. Therefore, it is not necessary to wrap the boxes A, B for integration in advance. Since the boxes A,B do not come against each other, corners or contents of the boxes may not be damaged.</p> |
