Description

【0001】
【発明の属する技術分野】
この発明は、家電製品等の梱包に使用する段ボール製緩衝材に関する。
【0002】
【従来の技術】
従来より、段ボール製緩衝材として、図6に示すように、底板50の周縁各辺に連設した側板51を起立させ、側板51の上縁に順次連設した頂板52及び外面板53を折り返した状態で外箱に内挿し、底板51に載せた物品の周囲に緩衝空間を確保して、物品を保護しようとするものが使用されている。
【0003】
【発明が解決しようとする課題】
しかしながら、上記のような緩衝材は、外箱で規制されて保形されるものであるため、作り置きができず、梱包時の作業性が悪いという問題がある。
【0004】
また、大きな外力が作用すると、側板が外側へ倒れるように変形して、十分な緩衝性が得られない場合もある。
【0005】
そこで、この発明は、組立状態で安定して保形され、緩衝性にも優れた段ボール製緩衝材を提供しようとするものである。
【0006】
【課題を解決するための手段】
上記課題を解決するため、この発明は、底板に連設した側板を起立させ、隣接する側板のうち、一方の側板の端部に屈曲した差込穴を設け、他方の側板の端縁に差込部を突設し、この差込部には、側板の起立時に下を向く揺動片を連設し、差込穴に差込部を、揺動片を折り曲げつつ差し込んで揺動片の戻りにより差込部を差込穴から抜け止めし、底板に対する側板の起立状態を維持することにより、組み立てた形状で安定するようにしたのである。
【0007】
さらに、前記外面板の両側部を斜めに切断し、材料使用量を抑制すると共に、段目を45°傾けることにより、各方向への均一な強度が得られるようにしたのである。
【0008】
【発明の実施の形態】
以下、この発明の実施の形態を添付図面に基づいて説明する。
【0009】
図1に示すように、この段ボール製緩衝材のブランクでは、底板1の両側縁に側板2が、両端縁に側板3が連設され、側板2、3には頂板4及び外面板5が順次先方へ連設されている。
【0010】
側板2の両端部には、屈曲した差込穴6が設けられ、この差込穴6は頂板4まで延びている。側板3の両端縁には差込部7が突設され、この差込部7には、側板3の起立時に下を向く揺動片8が連設されている。各側板2、3の基端には、底板1を切り込んで脚片9が突設されている。
【0011】
また、頂板4は複数の切目で分割され、両端のものを基準にして、その間の各頂板4と側板2、3及び外面板5の稜線は切目を挟んで交互にずらされている。
【0012】
そして、外面板5の両側部は斜めに切断され、このブランクの段目は、45°傾けられている。
【0013】
このブランクを図2に示すように組み立てるには、底板1から側板2、3を起立させ、頂板4及び外面板5を折り返す。
【0014】
このとき、図3及び図4に示すように、両端の頂板4を重ね合わせつつ、差込穴6に差込部7を差し込むと、揺動片8の戻りにより、差込部7は差込穴6から抜け止めされ、底板1に対する側板2の起立状態が維持される。
【0015】
なお、上記組立過程において、差込穴6に差込部7を差し込む際、揺動片8を手で折り曲げてもよいが、揺動片8の先端角部に丸みをつけておくと、その部分が差込穴6の屈曲した端縁に当接して、揺動片8は自然に折れ曲がる。
【0016】
このように組み立てた緩衝材10は、図2に示すような形状で安定するので、作り置きしておくこともでき、図5に示すように、外箱11に容易に挿入することができる。
【0017】
また、この組立状態において、頂板4は互い違いに傾斜し、側板2、3と外面板5の間隔が確実に維持されるので、底板1の上面に載置した物品の周囲には緩衝空間が確保される。
【0018】
さらに、脚片9が下方に突出して、底板1は脚片9と外面板5により浮上支持されるので、物品の下方にも緩衝空間が確保される。
【0019】
また、外箱11のフラップ12を折り返して、その稜部を交互に傾けると、中蓋13と上蓋14の間隔が維持され、物品の上方にも緩衝空間が確保される。
【0020】
そのほか、この緩衝材は、図1に示すブランクにおいて、外面板5の両側部を斜めに切断し、段目を45°傾けたので、各方向への均一な強度が得られるだけでなく、段ボールシート上に各緩衝材のブランクを斜辺同士が接するように配置することにより、効率よく材料取りをして、材料の使用量を抑制できる。
【0021】
【発明の効果】
以上のように、この発明に係る段ボール製緩衝材は、隣接する側板の一方の差込穴に他方の差込部を差し込んで揺動片の戻りにより抜け止めし、底板に対する側板の起立状態を維持することとしたので、組立状態で安定して保形され、作り置きしておくことができ、梱包作業の能率を向上させることができる。
【0022】
さらに、外面板の両側部を斜めに切断し、段目を45°傾けたので、各方向への均一な強度が得られ、材料使用量も抑制できる。

BACKGROUND OF THE INVENTION
The present invention relates to a corrugated cardboard cushioning material used for packaging home appliances and the like.
[0002]
[Prior art]
Conventionally, as a corrugated cardboard cushioning material, as shown in FIG. 6, a side plate 51 connected to each side of the periphery of the bottom plate 50 is erected, and a top plate 52 and an outer surface plate 53 that are sequentially connected to the upper edge of the side plate 51 are folded back. In order to protect the article, a buffer space is secured around the article placed in the outer box and placed on the bottom plate 51.
[0003]
[Problems to be solved by the invention]
However, since the cushioning material as described above is regulated and retained by the outer box, there is a problem that it cannot be made and the workability at the time of packing is poor.
[0004]
In addition, when a large external force is applied, the side plate may be deformed so as to fall outward, and sufficient buffering properties may not be obtained.
[0005]
Accordingly, the present invention is to provide a corrugated cardboard cushioning material that is stably retained in an assembled state and has excellent cushioning properties.
[0006]
[Means for Solving the Problems]
To solve the above problems, the present invention is to erect the side plate which is provided continuously to the bottom plate, of the adjacent side plate, provided an insertion hole which is bent at an end of one side plate, the difference in the edge of the other side plate write unit projecting the, this insertion portion, the rocking piece faces downward when the side plate of the upstanding consecutively provided, the insertion portion insertion hole, insert while bending the swinging piece, the swing piece Thus, the insertion portion is prevented from coming out of the insertion hole by the return, and the standing state of the side plate with respect to the bottom plate is maintained, so that the assembled shape is stabilized.
[0007]
Further, both sides of the outer plate are cut obliquely to reduce the amount of material used, and the step is inclined 45 ° to obtain uniform strength in each direction.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
[0009]
As shown in FIG. 1, in this cardboard cushion blank, side plates 2 are connected to both side edges of the bottom plate 1, side plates 3 are connected to both end edges, and a top plate 4 and an outer surface plate 5 are sequentially connected to the side plates 2 and 3. It is connected to the other side.
[0010]
Bent insertion holes 6 are provided at both ends of the side plate 2, and the insertion holes 6 extend to the top plate 4. Insertion portions 7 project from both end edges of the side plate 3, and swing pieces 8 that face downward when the side plate 3 stands are connected to the insertion portion 7. At the base ends of the side plates 2 and 3, leg pieces 9 project from the bottom plate 1.
[0011]
Further, the top plate 4 is divided by a plurality of cuts, and the ridgelines of the top plate 4 and the side plates 2 and 3 and the outer plate 5 between them are alternately shifted with the cuts in between.
[0012]
Then, both side portions of the outer surface plate 5 are cut obliquely, and the steps of the blank are inclined 45 °.
[0013]
In order to assemble this blank as shown in FIG. 2, the side plates 2 and 3 are erected from the bottom plate 1, and the top plate 4 and the outer surface plate 5 are folded back.
[0014]
At this time, as shown in FIGS. 3 and 4, when the insertion portion 7 is inserted into the insertion hole 6 while the top plates 4 at both ends are overlapped, the insertion portion 7 is inserted due to the return of the swing piece 8. The side plate 2 is prevented from coming off from the hole 6 and the standing state of the side plate 2 with respect to the bottom plate 1 is maintained.
[0015]
In the above assembly process, when inserting the insertion portion 7 into the insertion hole 6, the swing piece 8 may be bent by hand, but if the tip corner of the swing piece 8 is rounded, The portion comes into contact with the bent edge of the insertion hole 6 and the swing piece 8 is bent naturally.
[0016]
Since the cushioning material 10 assembled in this way is stable in a shape as shown in FIG. 2, it can also be prepared, and can be easily inserted into the outer box 11 as shown in FIG. 5.
[0017]
Further, in this assembled state, the top plate 4 is alternately inclined, and the space between the side plates 2 and 3 and the outer surface plate 5 is reliably maintained, so that a buffer space is secured around the article placed on the upper surface of the bottom plate 1. Is done.
[0018]
Furthermore, since the leg piece 9 protrudes downward and the bottom plate 1 is floated and supported by the leg piece 9 and the outer surface plate 5, a buffer space is also secured below the article.
[0019]
Further, when the flap 12 of the outer box 11 is folded back and the ridges are alternately inclined, the distance between the inner lid 13 and the upper lid 14 is maintained, and a buffer space is secured above the article.
[0020]
In addition, since this cushioning material has a blank shown in FIG. 1, both sides of the outer surface plate 5 are cut obliquely and the step is inclined by 45 °, so that not only uniform strength in each direction can be obtained, but also cardboard By arranging the cushion blanks on the sheet so that the hypotenuses are in contact with each other, the material can be efficiently taken and the amount of the material used can be suppressed.
[0021]
【The invention's effect】
As described above, the cushioning material made of corrugated cardboard according to the present invention inserts the other insertion portion into one insertion hole of the adjacent side plate and prevents it from coming off by the return of the swinging piece. Since it has been maintained, the shape can be stably maintained in the assembled state, can be kept, and the efficiency of the packing operation can be improved.
[0022]
Furthermore, since both sides of the outer plate are cut obliquely and the step is inclined by 45 °, uniform strength in each direction can be obtained, and the amount of material used can be suppressed.
