Description

本発明は、例えば段ボール製の包装箱内において製品を支持するための包装用緩衝体に関する。   The present invention relates to a packaging buffer for supporting a product in a packaging box made of cardboard, for example.

従来、製品(包装物)を輸送するために梱包する際、段ボール製の包装箱内において製品を緩衝体によって支持することが行われている。この緩衝体としては、段ボール製緩衝体、又は成型した発泡樹脂が用いられることがある。しかし、段ボール製緩衝体は、製品に合った形状で保持するために設計工数、金型、製造コスト等に加え組み立て工数が多大であった。また、発泡樹脂の緩衝体は、組み立て工数が必要ないが、保管容積が膨大であり、やはり製品に合った形状で保持するために設計工数、金型、製造コストが掛かっていた。   Conventionally, when a product (package) is packed for transportation, the product is supported by a buffer in a cardboard packaging box. As this buffer, a cardboard buffer or a molded foamed resin may be used. However, in order to hold the corrugated cardboard cushion in a shape suitable for the product, the assembly man-hour is great in addition to the design man-hour, the mold, the manufacturing cost, and the like. In addition, the foamed resin cushion does not require assembling man-hours, but the storage volume is enormous, and it still takes design man-hours, molds, and manufacturing costs in order to retain the shape suitable for the product.

そこで、形状の異なる製品に対しても融通が利き保管容積をとらない緩衝体として、シート状の段ボール材を用いて折り曲げて構成し、中央部に穴をあけポリウレタンフィルムのような可撓性フィルムを溶着したものが考案されている(下記特許文献1,2参照)。
実用新案登録第3070395号公報 実用新案登録第3076355号公報
Therefore, a flexible film such as a polyurethane film is formed by folding a sheet-like corrugated cardboard material as a cushioning body that is flexible and does not take up storage space even for products with different shapes, and has a hole in the center. Have been devised (see Patent Documents 1 and 2 below).
Utility Model Registration No. 3070395 Utility Model Registration No. 3076355

しかしながら、上記特許文献1,2に記載された緩衝体においては、シート状の段ボール材から緩衝体を事前に組み立てる必要があったことから、包装作業を行う現場では包装作業とは別に緩衝体を組み立てる工程を設けなければならず、工程作業の増加、組み立てた緩衝体の一時保管場所確保などの問題が発生していた。   However, in the shock absorbers described in Patent Documents 1 and 2, the shock absorber must be assembled in advance from the sheet-like cardboard material. A process for assembling had to be provided, and problems such as an increase in process work and securing a temporary storage place for the assembled buffer body occurred.

また、段ボールと可撓性フィルムの固着に特殊な方法を用いていたことから容易に生産拠点を増やせないため、供給地域が限定されていた。また、緩衝体は接着方法が複雑なものもあり、分別廃棄の際手間も掛かっていた。   In addition, since a special method is used for fixing the corrugated cardboard and the flexible film, the number of production bases cannot be increased easily, so the supply area is limited. In addition, some buffer bodies have complicated bonding methods, and it takes time and labor to separate and discard.

本発明の目的は、製品に対応した新規設計の必要性が無く、組み立て工数もほとんど必要なく、保管容積も少ない簡易な包装用緩衝体を提供することにある。また、使用後容易に分解すことができ、環境負荷を軽減するよう考慮された包装用緩衝体を提供することにある。   An object of the present invention is to provide a simple packaging buffer body that does not require a new design corresponding to a product, requires almost no assembly steps, and has a small storage volume. Another object of the present invention is to provide a packaging buffer that can be easily disassembled after use and is designed to reduce the environmental load.

本発明の包装用緩衝体は、中央に開口部を有する略四角形の紙製シート上に、可撓性フィルムを載置し、各角部のみにおいて両者を両面粘着性テープで固着した包装用緩衝体であって、前記紙製シートの各辺部に平行に折り曲げ罫線が有り、前記罫線に沿って凸折りに曲げて側壁を形成し、前記各角部に3本の折り曲げ罫線が有り、外側の2本の罫線に沿って凸折りに曲げ中心の罫線に沿って凹折りに曲げたことを特徴とする。 The packaging buffer of the present invention is a packaging buffer in which a flexible film is placed on a substantially square paper sheet having an opening in the center, and both are fixed with double-sided adhesive tape only at each corner. a body, there is a parallel folding borders on each side of the paper-made sheet to form a side wall by bending the folded protruding along the borders, the three pieces of folded borders to each corner there, outside It is characterized in that it is bent into a convex fold along the two ruled lines and bent into a concave fold along the central ruled line.

本発明の包装用緩衝体により、第1の効果として、組み立ては紙製シートの一部を折り曲げて包装箱に収めることにより形状を保持する構造のため、シート状態で保管が可能で、組み立てが容易であり、保管スペース、及び組み立て工数を削減することができる。また、紙製シートと可撓性フィルムの接着強度が高められる。 With the packaging cushion of the present invention, as a first effect, assembling is a structure that holds a shape by folding a part of a paper sheet and placing it in a packaging box, so that it can be stored in a sheet state and assembled. It is easy, and storage space and assembly man-hours can be reduced. Moreover, the adhesive strength between the paper sheet and the flexible film is increased.

第2の効果は、従来の包装用緩衝体に比べ材料の使用量が少なく、加工工程や材料も特殊なものではなく生産拠点を容易に増やすことが可能になり、供給可能地域が大幅に広がった。また、使用後の可撓性フィルムとの分別も容易なため、環境負荷が軽減できる。   The second effect is that the amount of material used is smaller than that of the conventional packaging buffer, the processing process and materials are not special, and it is possible to easily increase the number of production bases, greatly expanding the supply area. It was. Moreover, since the separation from the flexible film after use is easy, the environmental load can be reduced.

第3の効果は、包装物に対して新たに包装用緩衝体の設計を行う場合も、緩衝体形状が単純で統一されているため、包装物の大きさ重量から容易に決めることができ、新規設計工数の大幅削減が可能である。   The third effect is that, even when a packaging cushion is newly designed for a package, since the shape of the cushion is simple and uniform, it can be easily determined from the size and weight of the package, New design man-hours can be greatly reduced.

次に、本発明の実施の形態について図面を参照して説明する。   Next, embodiments of the present invention will be described with reference to the drawings.

図1は、本発明の紙製シートと可撓性フィルムから成る包装用緩衝体を示す図である。   FIG. 1 is a view showing a packaging cushion comprising a paper sheet and a flexible film of the present invention.

図1において、包装用緩衝体1は、折り曲げ罫線を付けた、例えば段ボール製の紙製シート2と、紙製シート2上に載置された、例えばポリウレタン製の可撓性フィルム3、両面粘着性テープ4で構成されている。紙製シート2は、略四角形であり、包装物の大きさに合わせ、シート材質及びシート寸法は任意とし、a,a,b,b,c,c,d,d,e〜eの凸折り罫線を有し、a,b,c,dの凹折り罫線を有する。 In FIG. 1, a packaging buffer 1 includes a paper sheet 2 made of, for example, corrugated cardboard, and a flexible film 3 made of, for example, polyurethane, placed on the paper sheet 2, with double-sided adhesive. It is comprised with the property tape 4. The paper sheet 2 has a substantially rectangular shape, the sheet material and the sheet dimensions are arbitrary according to the size of the package, and a 1 , a 2 , b 1 , b 2 , c 1 , c 2 , d 1 , d 2 , e 1 to e 4 convex crease lines, and a 3 , b 3 , c 3 , d 3 concave crease lines.

凸折り罫線e〜eは、各辺に平行であり、凸折り罫線a,a,b,b,c,c,d,dは、各角部において凸折り罫線e〜eの交点(後述の図2の頂部に対応)から辺に向かって一対設けられ、その中心(2等分線)に凹折り罫線a,b,c,dが、角部先端に向かって一本設けられている。 The convex folding ruled lines e 1 to e 4 are parallel to each side, and the convex folding ruled lines a 1 , a 2 , b 1 , b 2 , c 1 , c 2 , d 1 , d 2 are convex at each corner. A pair of folding ruled lines e 1 to e 4 (corresponding to the top of FIG. 2 described later) is provided toward the side, and concave folded ruled lines a 3 , b 3 , c 3 , d are formed at the center (bisector). 3 is provided toward the tip of the corner.

ここで、紙製シート2の各角部の先端は、辺の延長線より後退させている。また、凸折り罫線a,a,b,b,c,c,d,dは、凸折り罫線e〜eのほぼ延長上にある。 Here, the tip of each corner of the paper sheet 2 is set back from the extension line of the side. Further, the convex folded ruled lines a 1 , a 2 , b 1 , b 2 , c 1 , c 2 , d 1 , and d 2 are substantially extended from the convex folded ruled lines e 1 to e 4 .

また、紙製シート2は、包装物の大きさに対応した切り抜き部分(開口部)fを有する。紙製シート2の折り曲げ罫線には、必要に応じてミシン目又は半切り線加工を施してある。半切り線というのは、カッタによって紙製シート2を厚さ方向の半分程度まで切り込むことによって形成された折り線のことである。   Further, the paper sheet 2 has a cutout portion (opening) f corresponding to the size of the package. The folding ruled line of the paper sheet 2 is perforated or half-cut as required. The half-cut line is a fold line formed by cutting the paper sheet 2 to about half in the thickness direction with a cutter.

また、紙製シート2と可撓性フィルム3は、角部において3本の罫線(左上部でいえばa1,a2,a3)に跨るように両面粘着性テープ4で接着する。両面粘着性テープ4の貼り合わせ箇所は、4カ所のみとする。可撓性フィルム3は、紙製シート2と大きさ、形状がほぼ同等とする。 Also, the paper sheet 2 and the flexible film 3 are bonded with a double-sided adhesive tape 4 so as to straddle three ruled lines (a 1 , a 2 , a 3 in the upper left) at the corners. There are only four places where the double-sided adhesive tape 4 is bonded . The flexible film 3 has substantially the same size and shape as the paper sheet 2.

図2(a),(b)は、包装用緩衝体を折り曲げ罫線に沿って折り曲げる状態を示す、上面図及び側面図である。なお、図2(a)において可撓性フィルム3と両面粘着性テープ4は、図示を省略している。   2A and 2B are a top view and a side view showing a state in which the packaging buffer is bent along the folding ruled line. In FIG. 2A, the flexible film 3 and the double-sided adhesive tape 4 are not shown.

図1においては、紙製シート2を折り曲げ罫線に沿って折り曲げる前の状態を示しており、可撓性フィルム3を載置し、角部において両者は両面粘着性テープ4で固着されている。   FIG. 1 shows a state before the paper sheet 2 is bent along the folding ruled lines, and a flexible film 3 is placed, and both are fixed by a double-sided adhesive tape 4 at corners.

図1に示す状態から、図2(a)で示すように、凸折り罫線e〜e、a,a,b,b,c,c,d,dに沿って外側に折り曲げ、凹折り罫線a,b,c,dに沿って内側に折り込む。それにより、各辺に沿って側壁が、a,b,c,dに頂部が形成され、図2(b)のように可撓性フィルム面が底面から一定の距離を保つようになる。さらに上記凹折り罫線a,b,c,dを内側に折り曲げることにより、紙製シート2と可撓性フィルム3を接着している両面粘着性テープ4を挟み込む形状となり、可撓性フィルム3の接着強度を高める役割を兼ねている。 From the state shown in FIG. 1, as shown in FIG. 2A, the convex folding ruled lines e 1 to e 4 , a 1 , a 2 , b 1 , b 2 , c 1 , c 2 , d 1 , d 2 are changed. Fold along the outer side and fold inward along the concave crease lines a 3 , b 3 , c 3 , and d 3 . As a result, the side walls along each side are formed with apexes at a 0 , b 0 , c 0 , and d 0 so that the flexible film surface keeps a certain distance from the bottom surface as shown in FIG. become. Furthermore, the concave folding ruled lines a 3 , b 3 , c 3 , and d 3 are folded inward to sandwich the double-sided adhesive tape 4 that bonds the paper sheet 2 and the flexible film 3, and the flexible It also serves to increase the adhesive strength of the conductive film 3.

また、頂部a,b,c,dを支点として可撓性フィルム3が鋭角に折り返されることにより、衝撃が加わった際に包装物5の自重により可撓性フィルム3が撓む現象を抑える役割を有している。 Further, the flexible film 3 is bent at an acute angle with the top portions a 0 , b 0 , c 0 , and d 0 as fulcrums, so that the flexible film 3 bends due to the weight of the package 5 when an impact is applied. It has a role to suppress the phenomenon.

図3は、包装用緩衝体を包装箱に入れて使用する場合の分解斜視図である。   FIG. 3 is an exploded perspective view in the case of using the packaging cushion in a packaging box.

図4は、包装用緩衝体を使用して包装物を梱包した状態を示す断面図である。   FIG. 4 is a cross-sectional view showing a state in which a package is packed using a packaging buffer.

一対の包装用緩衝体1を、例えば段ボール製の包装箱6に入れ込み、可撓性フィルム3を対向させるように配置して、両側から挟み込みように包装物5を中間で保持する。包装物5は、紙製シート2の開口部fにおける可撓性フィルム3により保持される。包装用緩衝体1は、側壁の広がりが包装箱6の内面との係合により規制され、形状が保持される。   A pair of packaging cushions 1 are placed in a packaging box 6 made of, for example, cardboard, and are arranged so that the flexible films 3 face each other, and the package 5 is held in the middle so as to be sandwiched from both sides. The package 5 is held by the flexible film 3 in the opening f of the paper sheet 2. In the packaging buffer 1, the expansion of the side wall is regulated by the engagement with the inner surface of the packaging box 6, and the shape is maintained.

この状態で、包装物は空間3次元の全ての方向に対し、可撓性フィルム3で保護されているため、衝撃を最小限に抑えることができる。   In this state, since the package is protected by the flexible film 3 in all three-dimensional directions, the impact can be minimized.

このように、本発明の包装用緩衝体は、折り曲げ罫線に沿って折りぐせをつける軽作業のみでよく、包装箱に収納することで形状を保持するため事前に緩衝体包装材を組み立てる必要がない。   In this way, the cushioning body for packaging according to the present invention requires only a light work for folding along the folding ruled line, and it is necessary to assemble the cushioning body packaging material in advance in order to maintain the shape by storing it in the packaging box. Absent.
