Description

【０００１】
【発明の属する技術分野】
この発明は、薄い重量物の梱包に適した段ボール製緩衝材に関する。
【０００２】
【従来の技術】
従来、高さが低くて重量のある機械部品等を梱包する際には、耐荷重性や成形性に優れた発泡スチロール製の緩衝材が使用されてきた。しかし、近年では、環境への影響を考慮して、このような製品の梱包に際しても、段ボール製の緩衝材が求められている。
【０００３】
ところで、上記のような用途の緩衝材を段ボール化する場合、通常の筒構造とすれば強度が不足するため、製品形状に応じて打ち抜いた段ボールシートを、底板上に多数枚積み重ねて貼り合わせた積層構造とする必要がある。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記のような積層構造の段ボール製緩衝材では、製造工程での打ち抜きに際し、抜き落として廃棄する部分が多く、材料が無駄になるという問題がある。
【０００５】
そこで、この発明は、材料を有効に利用して製造でき、強度にも優れた積層構造の段ボール製緩衝材を提供することを課題とする。
【０００６】
【課題を解決するための手段】
上記課題を解決するため、この発明に係る段ボール製緩衝材は、段ボールシートを二つ折りにして内外二重の底板を形成し、各底板の両側部分を巻き込んで、張力を作用させつつ折り重ねた構造を採用したのである。
【０００７】
【発明の実施の形態】
以下、この発明の実施形態を添付図面に基づいて説明する。
【０００８】
この段ボール製緩衝材は、図１に示すように、段ボールシートを長方形に打ち抜いたブランクから形成され、このブランクでは、内底板１と外底板２とが一方の端縁に設けられた二箇所の繋部で繋がっている。そして、内底板１の両側には内立板３、２枚の内枠板４及び端底板５が順次連設され、外底板２の両側には外立板６、外枠板７及び底受板８が順次連設されている。
【０００９】
内枠板４は２枚に跨がって切り抜かれ、外枠板７は底受板８が食い込むように切り込まれて、この切抜及び切込によりそれぞれ製品収納部９，１０が形成されている。製品収納部９，１０の端縁には添当片１１，１２が連設され、端底板５には係合穴１３，１４が形成されている。また、底受板８の内縁部には係合片１５が設けられ、内底板１及び外底板２には係合穴１６が形成されている。
【００１０】
上記ブランクから緩衝材を組み立てるには、図２に示すように、まず、内底板１と外底板２とを折り重ね、内立板３及び２枚の内枠板４を巻き込み、端底板５を折り返して内底板１に重ねる。
【００１１】
次いで、図３に示すように、外立板６、外枠板７及び底受板８を巻き込み、底受板８の端縁を端底板５の端縁に当接させて、外枠板７に張力を作用させつつ、底受板８を内底板１に折り重ねる。
【００１２】
そして、図４に示すように、係合片１５を係合穴１６に押し込んで保形すると共に、添当片１１，１２を下方へ折り曲げて、その先端部を係合穴１３，１４にそれぞれ差し込む。
【００１３】
このように構成した段ボール製緩衝材は、ブランクの製造に際し、抜き落とす部分が少ないので、材料を効率よく使用して製造でき、かつ引張力が作用した積層構造であることから、剛性に優れたものとなる。
【００１４】
また、この形態では、外枠板７の両側部分がスロープ状となるので、筒構造のように、直角に屈曲した固い稜部が形成されず、製品収納部１０の端縁が製品に柔らかく当接して、製品が保護される。
【００１５】
【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、長方形状の段ボールシートを二つ折りにして内外二重の底板を形成し、各底板の両側部分を巻き込んで張力を作用させつつ折り重ねた構造としたので、材料を効率よく使用でき、剛性に優れたものとなる。

BACKGROUND OF THE INVENTION
The present invention relates to a corrugated cardboard cushioning material suitable for packing a thin heavy object.
[0002]
[Prior art]
Conventionally, when packing high-weight and heavy mechanical parts, etc., a cushioning material made of foamed polystyrene having excellent load resistance and moldability has been used. However, in recent years, considering the influence on the environment, a corrugated cardboard cushioning material is also required for packaging such products.
[0003]
By the way, when cushioning materials for the above uses are made into corrugated cardboard, the strength is insufficient if a normal cylindrical structure is used, so a number of corrugated cardboard sheets punched in accordance with the product shape are stacked and bonded on the bottom plate. It is necessary to have a laminated structure.
[0004]
[Problems to be solved by the invention]
However, the cardboard cushioning material having the laminated structure as described above has a problem that the material is wasted because there are many portions to be discarded when it is punched in the manufacturing process.
[0005]
Therefore, an object of the present invention is to provide a corrugated cardboard cushioning material having a laminated structure that can be manufactured by effectively using materials and has excellent strength.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the cushioning material made of corrugated cardboard according to the present invention is formed by folding the corrugated cardboard sheet in half to form an inner / outer double bottom plate, and wrapping both sides of each bottom plate while applying tension. The structure was adopted.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
[0008]
As shown in FIG. 1, the cardboard cushioning material is formed from a blank obtained by punching a corrugated cardboard sheet into a rectangle, and in this blank, the inner bottom plate 1 and the outer bottom plate 2 are provided at one end edge. Connected at the connection. Further, an inner plate 3, two inner frame plates 4 and an end bottom plate 5 are successively arranged on both sides of the inner bottom plate 1, and an outer plate 6, an outer frame plate 7 and a bottom support are arranged on both sides of the outer bottom plate 2. The plates 8 are sequentially connected.
[0009]
The inner frame plate 4 is cut out over two sheets, and the outer frame plate 7 is cut so that the bottom receiving plate 8 bites in, and the product storage portions 9 and 10 are formed by the cut and cut, respectively. Yes. At the end edges of the product storage portions 9 and 10, attachment pieces 11 and 12 are continuously provided, and the end bottom plate 5 is formed with engagement holes 13 and 14. An engagement piece 15 is provided at the inner edge of the bottom receiving plate 8, and an engagement hole 16 is formed in the inner bottom plate 1 and the outer bottom plate 2.
[0010]
To assemble the cushioning material from the blank, as shown in FIG. 2, first, the inner bottom plate 1 and the outer bottom plate 2 are folded, the inner plate 3 and the two inner frame plates 4 are wound, and the end bottom plate 5 is Fold it over and place it on the inner bottom plate 1.
[0011]
Next, as shown in FIG. 3, the upright plate 6, the outer frame plate 7 and the bottom receiving plate 8 are rolled up, and the end edge of the bottom receiving plate 8 is brought into contact with the end edge of the end bottom plate 5. The bottom receiving plate 8 is folded over the inner bottom plate 1 while applying a tension to the inner bottom plate 1.
[0012]
Then, as shown in FIG. 4, the engaging piece 15 is pushed into the engaging hole 16 to retain the shape, and the abutting pieces 11 and 12 are bent downward, and the tip portions thereof are engaged with the engaging holes 13 and 14, respectively. Plug in.
[0013]
The cushioning material made of corrugated cardboard as described above has excellent rigidity because it has a laminated structure in which the material can be manufactured efficiently and tensile force is applied because there are few parts to be removed when manufacturing a blank. It will be a thing.
[0014]
Further, in this embodiment, since both side portions of the outer frame plate 7 are sloped, a hard ridge portion bent at a right angle is not formed unlike the cylindrical structure, and the edge of the product storage portion 10 is softly applied to the product. In contact, the product is protected.
[0015]
【The invention's effect】
As described above, the corrugated cardboard cushioning material according to the present invention is formed by folding a rectangular corrugated cardboard sheet in half to form an inner / outer double bottom plate, and folding both sides of each bottom plate while applying tension. Since it has a structure, the material can be used efficiently and has excellent rigidity.
