Thereafter, the buffer member 20 is inserted into the outer box 10 from the predetermined second side wall 30 side, the inner flap 14 is bent, the outer flap 15 is bent, and sealed by a known fixing means such as an adhesive tape. .

この収容状態では、平面視正方形状の外箱１０に対して平面視八角形状の緩衝部材２０を収容させているため、その四隅、具体的には緩衝部材２０の第１側壁部２２と外箱１０との間には収容空間が形成されることになる。そのため、緩衝部材２０の外側に進出させたコネクタ４は勿論、他の付属品を収容させることができる。また、緩衝部材２０の外側壁は、八角筒状をなすため、円形状をなす笠３の外周部との接触部分が多く、安定状態で収容できるとともに、確実な緩衝作用を得ることができる。その結果、収容した商品を確実に外力から保護することができる。   In this accommodated state, since the cushioning member 20 having an octagonal shape in plan view is accommodated in the outer box 10 having a square shape in plan view, its four corners, specifically, the first side wall portion 22 and the outer case of the cushioning member 20 are accommodated. An accommodation space is formed between the two. Therefore, other accessories can be accommodated as well as the connector 4 advanced to the outside of the buffer member 20. Further, since the outer wall of the buffer member 20 has an octagonal cylindrical shape, there are many contact portions with the outer peripheral portion of the circular shade 3 so that it can be housed in a stable state and a reliable buffer action can be obtained. As a result, the stored product can be reliably protected from external force.

そして、本発明の緩衝部材２０は、連続した一枚のブランクからなるため、部品点数を削減でき、コストダウンを図ることができる。また、外箱１０の内部では、八角筒状をなす外周壁が上下方向に延びるため、耐圧強度を向上できる。その結果、外箱１０を形成する段ボール紙は、比較的軟質で安価なものを使用でき、トータルコストを大幅に低減できる。   And since the buffer member 20 of this invention consists of one continuous blank, it can reduce a number of parts and can aim at cost reduction. Moreover, since the outer peripheral wall having an octagonal cylindrical shape extends in the vertical direction inside the outer box 10, the pressure resistance can be improved. As a result, the corrugated paper forming the outer box 10 can be relatively soft and inexpensive, and the total cost can be greatly reduced.

一方、この包装箱に収容した照明器具１を取り出す場合には、外箱１０のフラップ１４，１５の固着を解除して開封する。そうすると、第２側壁部３０が露出するため、その把持孔３２，３８に手を差し込んで引き出すことにより、照明器具１と一緒に緩衝部材２０を外箱１０から簡単に取り出すことができる。   On the other hand, when taking out the luminaire 1 accommodated in the packaging box, the flaps 14 and 15 of the outer box 10 are released from being fixed and opened. Then, since the second side wall portion 30 is exposed, the buffer member 20 can be easily taken out from the outer box 10 together with the lighting fixture 1 by inserting a hand into the gripping holes 32 and 38 and pulling it out.

Thus, you may comprise by four cut-and-raised pieces 39A-39D provided with the continuous part 40 and the bending part 41. FIG. In this case, when the cut and raised pieces 39 </ b> A to 39 </ b> D are cut and raised to form the inner side wall, the bent portions 41 are folded and overlapped with the continuous portions 40 of the adjacent cut and raised pieces 39 </ b> B to 39 </ b> A, Is locked in the locking groove 43. Of course, it is also possible to form a triangular cylindrical inner wall by three cut and raised pieces. That is, the present invention includes all of the configurations in which two or more cut and raised pieces each having a continuous portion and a bent portion are provided and these overlapping portions are connected by a predetermined connecting means.

また、前記実施形態では、底壁２１を平面視八角形状で形成したが、外箱１０と同様の四角形状であってもよく、その角数も希望に応じて変更が可能である。さらに、外側壁を構成する側壁部２２，３０は、第１側壁部２２に巻込片２７を設け、第２側壁部２２に連設した折返壁部３４で巻き込むように組み立てる構成としたが、その構成の種々の変更が可能である。   Moreover, in the said embodiment, although the bottom wall 21 was formed in the planar view octagonal shape, the same rectangular shape as the outer case 10 may be sufficient, and the number of corners can also be changed as desired. Furthermore, although the side wall parts 22 and 30 which comprise an outer side wall were set as the structure assembled by providing the winding piece 27 in the 1st side wall part 22 and winding up with the folding | turning wall part 34 provided in a row by the 2nd side wall part 22, Various changes in the configuration are possible.
