  In the case of the packaging container of Patent Document 1, since the inner peripheral wall is fixed to the outer peripheral wall only at two places, there is a problem that a sufficient buffering effect cannot be obtained depending on the direction of impact applied from the outside. For example, when an impact is applied from the outside of the packaging container in the direction of the line connecting the two locations where the inner peripheral wall and the outer periphery are fixed, a strong force is applied in the direction of the outer peripheral wall that is faced by the fixed portion. However, the impact is absorbed by the flexibility of the inner peripheral wall itself, and a large impact is not transmitted to the contents. However, when an impact is applied in a direction perpendicular to the line connecting the two locations, a force in the bending direction acts on the two fixed portions of the inner peripheral wall, and the force for holding the contents is weak, and the entire inner peripheral wall It moves in the direction of impact and collides with the outer peripheral surface facing, and a large impact is transmitted to the contents. Therefore, depending on the direction of impact, the buffering effect is weakened, and there is a risk of damage to the contents.

  Moreover, when assembling the said packaging container from a box body formation piece, after sticking a predetermined location, most parts are assembled by one touch by raising an outer peripheral wall and making it a cylindrical box body. However, when the outer peripheral wall that overlaps flatly is caused, the portion that becomes the support portion is bent outward along the inner peripheral wall, so that the L-shaped support portion is separately folded inward. The work to form is necessary. Therefore, it takes time to assemble.

The three portions are extended and fixed to the inner peripheral surface of the outer cylindrical body S1. Therefore, no matter which direction of the outer peripheral surface of the outer cylindrical body S1 is applied, the accommodating portion S2 does not contact the outer cylindrical body S1, and the impact is absorbed by the flexibility of the accommodating portion S2 itself. A large impact is not transmitted to the contents W in S2. In addition, since the stored item W in the storage unit S2 is supported from below by the stored item holding unit 110, the packaging box 10 with a buffer function is used for normal handling in which the lower cover piece 44 side is left. On the other hand, a sufficient buffering effect can be obtained.

Further, it is possible to store instructions or the like in the gap between the front partition plate 64 and the front plate 16, and other gaps can be used as appropriate.

In addition, the packaging box with a buffer function of this invention is not limited to the said embodiment. For example, the material of the box-forming piece is preferably paper, for example, and the selection of the material and the setting of the thickness can be appropriately changed in view of the impact resistance and design of the contents. In particular, when there is a risk of being handled randomly during transportation, the shape and arrangement of the first to third crease lines and the first to ninth crease lines so that the distance between the outer cylindrical body and the accommodating portion is widened. Is preferably set.
In the above-described method of assembling the box-forming piece 12, as shown in FIG. 10, the glue 118 applied to the surface of the glue piece 96 is changed to the glue 118a on the back surface of the back plate 20, and the first glue portion Even if the glue 120 applied to the surface of 84 is changed to the glue 120a on the back surface of the second side plate 18 and the glue 122 applied to the surface of the third side plate is changed to the glue 122a on the back surface of the first side plate 14. Good. In this way, all the glue including the glues 114 and 116 is applied to the back surface of the box-forming piece 12, so that all the glue is applied at a time, and then each crease line is applied as described above. It can be assembled efficiently just by bending in order.

  Moreover, the structure of an upper cover and a lower cover can be changed freely. For example, as in a modification of the packaging box 10 shown in FIG. 11A, opening cut lines 132 and 134 are provided in place of the crease lines 56 and 58 of the upper lid piece 52, and the upper lid piece 52 is opened. The knobs 52a and 52b are respectively provided at the start ends of the cutting lines 132 and 134, so that an upper lid that can be easily opened by an elderly person or a handicapped person can be configured.
