The intermediate cushioning frame 118 and the packaging box 116 of this embodiment can also obtain the same effect as the intermediate cushioning frame 14 and the packaging box 10 described above. Since there is a possibility that the bottle-shaped container B may come into contact with the rear plate 18 when the bottle-shaped container B is housed in the cushioning middle frame 14, the rear plate 18 should not come into contact with the side surface of the outer casing 12. Tongue-shaped portions 26(1) and 26(2) are provided to improve the cushioning performance. However, in the case of the cushioning middle frame 118, when the bottle-shaped container B is accommodated, the bottle-shaped container B does not move around the inner peripheral edges of the second and third openings 140a and 180 and the guide plates 158(1) and 158(1). It is guided by (2) and does not come into contact with the back plate 122 . Therefore, even if the back plate 18 comes into contact with the side surface of the outer case 12, the same level of cushioning performance can be obtained, so the tongue-shaped portions 26(1) and 26(2) as described above are not provided.

The cushioning inner frame of the present invention and the packaging box using the same are not limited to the above embodiments. For example, since there is a possibility that the bottle-shaped container B comes into contact with the back plate 18 while the bottle-shaped container B is accommodated in the cushioning middle frame 14, the tongue-shaped portions 26(1) and 26() are provided just in case. 2) is provided, but the tongue-like portions 26(1) and 26(2) can be omitted if the cushioning performance is obtained. For example, when the bottle-shaped container B is accommodated, the inner side plates 32(1) and 32(2) are pushed by the side surfaces of the bottle-shaped container B and flex outward. In the case of a structure in which the side of the bottle-shaped container B is sandwiched, the bottle-shaped container B does not come into contact with the back plate 18, so the same cushioning performance can be achieved without providing the tongue-shaped portions 26(1) and 26(2). is obtained. Further, in order to further improve the shock-absorbing performance, a structure such as the auxiliary partition portion 128 of the shock-absorbing inner frame 118 may be added to protect the upper end of the bottle-shaped container B as well.

In order to improve the cushioning performance of the cushioning middle frame 118, the front plate 136 is provided with flaps 144(1) and 144(2), and guide plates 158(1) are provided on both sides of the lower horizontal plate 154. , 158(2), a pair of side plates 124(1) and 124(2) on both sides of the back plate 122, and an auxiliary partition 128, the necessary cushioning performance is obtained.
