In addition, the packaging box with a cushioning function of the present invention is not limited to the above embodiment. For example, the above six embodiments vary in the number of lid flaps forming the first lid surface and the second lid surface and in the overlapping order. Moreover, there are those that have a partition forming plate and a buffer forming plate and those that do not. As can be seen from this, in the packaging box with shock absorbing function of the present invention, when the open end of the cylindrical body is closed with the lid surface, the auxiliary plate curves inward to appropriately form a space for shock absorbing. If so, the structure of the lid surface can be freely changed, and whether or not to provide the partition forming plate or the buffer forming plate can be freely selected.

In the description of each of the above embodiments, in a particular state during assembly, "the first crease line and the first auxiliary crease line are close to each other", "the second crease line and the second auxiliary crease line close to each other,” he said. The fact that two corresponding folding lines are "close to each other" includes both a state in which they are slightly displaced and a state in which they overlap, and the optimum positional relationship differs depending on the situation. In practice, a prototype packing box with a cushioning function is made, and when the open end of the cylindrical body is closed with the lid surface, the auxiliary plate is curved inward and adjusted appropriately so that a space for cushioning is appropriately formed. is preferred. For example, if the thickness of the box-forming piece is relatively thin, by slightly shifting the positions of the two crease lines, the auxiliary plate can be easily bent. It is advisable to take into consideration the fact that the auxiliary plate can be bent without any problem even if it is in the overlapping position.
