Description
【０００１】[0001]
本考案は、凸部と凹部とが交互に連続して形成されており、１以上の凸部及び 凹部がそれぞれ係合せしめられて前後方向に接合されてから表裏面に紙製やプラ スチック製のライナを積層されて段ボールを構成される段ボールの波型中芯に関 するものである。 According to the present invention, the convex portions and the concave portions are alternately formed continuously, and one or more convex portions and concave portions are engaged with each other and joined in the front-rear direction, and then the front and back surfaces are made of paper or plastic. It is related to corrugated corrugated cores of corrugated cardboard that are constructed by stacking liners of the above.
【０００２】[0002]
従来、生鮮食品等を収納されて運搬される容器として、凸部と凹部とが交互に 連続して形成されている波型中芯の表裏面に紙製やプラスチック製のライナ（以 下、単にライナと言う）を積層された段ボールを用いて構成された函が広く使用 されている。 この函は、波型中芯の表裏面にライナを積層されて所定の大きさに切断し所定 の箇所に折目線をなす罫線を形成した段ボールを該罫線で折曲することによって 構成されていた。 Conventionally, a liner made of paper or plastic (hereinafter, simply referred to as a liner on the front and back surfaces of a corrugated core in which convex portions and concave portions are alternately and continuously formed as a container for accommodating and transporting fresh food, etc. Boxes made of corrugated cardboard with laminated liners are widely used. This box was constructed by stacking liners on the front and back surfaces of a corrugated core, cutting it into a predetermined size, and folding the corrugated cardboard on which a crease line was formed at a predetermined location. .
【０００３】 このような波型中芯は、従来凹部と凸部とが交互に連続する形状に形成された 紙製のものを使用されていたが、近年優れた断熱性及び強い強度を有する発泡プ ラスチックシートよりなるものが使用されるようになってきた。 発泡プラスチックシートよりなる波型中芯は、通常定尺の発泡プラスチックシ ートに金型等によって凹部と凸部とが交互に連続する形状に形成されていたので ある。従って、定尺の発泡プラスチックシートで形成された波型中芯（以下、定 尺の波型中芯ということがある）より更に大きな面積を有する波型中芯にライナ を積層した広い面積を有する段ボールを要求される場合には、長さ方向に並べた 定尺の波型中芯の表裏面にライナを積層して広い面積を有する段ボールを製造し ていたのである。従来この広い面積を有する段ボールを製造するには、例えば図 ４(イ)に示す如く定尺の波型中芯１'の後端縁に次に並べられる定尺の波型中芯 １'の前端縁を突き合わせたり、図４(ロ)に示す如く定尺の波型中芯１'の後端部 と次に並べられる定尺の波型中芯１'の前端縁とのそれぞれ凸部1b'同士及び凹部 1c'同士を重ね合わせたりして接合し、定尺の波型中芯１'を十分な面積を有する 状態にしてからこの波型中芯１'の表裏面にライナ５を積層された段ボールが使 用されていた。Conventionally, as such a corrugated core, a paper-made core in which concave portions and convex portions are alternately continuous is used, but in recent years, a foam having excellent heat insulation and strong strength has been used. Those made of plastic sheets have come into use. The corrugated core made of a foamed plastic sheet is usually formed in a regular-sized foamed plastic sheet by a mold or the like so that concave portions and convex portions are alternately continuous. Therefore, it has a large area in which the liner is laminated on the corrugated core having a larger area than that of the corrugated core formed of a standard-sized foamed plastic sheet (hereinafter, also referred to as a standard corrugated core). When corrugated board is required, liners were laminated on the front and back surfaces of a regular length corrugated core arranged in the length direction to produce corrugated board having a large area. Conventionally, in order to manufacture a corrugated board having such a large area, for example, as shown in FIG. 4 (a), a regular-sized corrugated core 1 ′ is arranged next to the rear end edge of the regular-corrugated core 1 ′. The front end edges are abutted against each other, or as shown in FIG. 4B, the convex portion 1b of each of the rear end portion of the standard-sized corrugated core 1'and the front edge of the next-arranged standard corrugated core 1 '. The liners 5 are laminated on the front and back surfaces of the corrugated core 1 ', by joining the'corrugated core 1'and the recessed portions 1c' by bonding them to each other so that the standard length corrugated core 1'has a sufficient area. The cardboard used was used.
【０００４】 しかしながら、波型中芯１'の接合部分1a'を前者の後端縁と前端縁とを突き合 わされて接合される場合には、波型中芯１'の本体に一定の間隔で形成されてい る凸部1b'の間隔に対して突き合わされている凸部1b'同士間の間隔が広くなり易 く、ライナ５を積層されたときにこの接合部分1a'の凸部1b'又は凹部1c'とライ ナ５とで形成される空間が大きくなるので断熱性及び強度が低下するという欠点 があり、更に隣接する波型中芯１'同士は何にも拘束されていないからズレが生 じ易くライナ５を積層する作業を効率良く行うことができないという欠点があっ た。更に、このような段ボールを使用して上述したように製造された函は、罫線 部分の強度が弱く外力が働くと簡単に折れ曲がったり、更に波型中芯１'の端縁 を突き合わされている部分に沿って罫線が形成されると罫線部分で破断が生じ易 いという欠点があった。However, when the joining portion 1a ′ of the corrugated core 1 ′ is joined by abutting the former rear end edge and the front end edge of the corrugated core 1 ′, the corrugated core 1 ′ is fixed to the main body. The gap between the protrusions 1b ′ abutting against the gap between the protrusions 1b ′ formed at intervals is easily widened, and when the liner 5 is laminated, the protrusions 1b ′ of the joint portion 1a ′ are stacked. The space formed by'or the recess 1c 'and the liner 5 becomes large, so that there is a drawback that the heat insulating property and the strength are deteriorated, and the adjacent corrugated cores 1'are not bound by anything. There is a drawback that the deviation is likely to occur and the work of stacking the liner 5 cannot be performed efficiently. Further, the box manufactured using the corrugated board as described above has a weakened crease line portion and is easily bent when an external force acts, and further, the edges of the corrugated core 1'are abutted against each other. When a ruled line is formed along the part, there is a drawback that the ruled line part is easily broken.
【０００５】 また、波型中芯１'の接合部分1a'が後者の端縁部分を重ね合わされた場合には 、ライナ５を積層された段ボールの厚さが波型中芯１'を重ね合わされた部分の みが他の部分より波型中芯１'の板厚ｔ分だけ厚く形成されて表面に凹凸を生じ るので表面性状が悪く、更に一般に段ボールの表面すなわちライナの表面に広告 や収容物の表示をすべく印刷が施されていることから、表面に凹凸を生じた部分 の近傍では美麗な印刷を行うことが困難で表面に印刷を施された段ボールの外観 が非常に悪いという欠点があった。更に、このような段ボールを使用して上述し たように函を製造しようとすると、波型中芯１'の端部の接合部分1a'には波型中 芯１'の板厚ｔ分に相当する段差が形成されているのでこの接合部分1a'に沿って 罫線が形成される場合にはこの罫線を一直線状に形成することが困難で所望の形 状の函を製造することができないだけでなく変形し易く強度の弱い函となるとい う欠点があった。When the joint portion 1a ′ of the corrugated core 1 ′ is overlapped with the latter edge portion, the thickness of the corrugated cardboard on which the liner 5 is laminated is overlapped with the corrugated core 1 ′. Since only the corrugated part is thicker than other parts by the plate thickness t of the corrugated core 1 ', and unevenness is generated on the surface, the surface quality is poor. Since it is printed to display objects, it is difficult to print beautifully in the vicinity of the uneven surface, and the appearance of the corrugated cardboard on the surface is very poor. was there. Furthermore, if an attempt is made to manufacture a box as described above using such corrugated cardboard, the joint portion 1a 'at the end of the corrugated core 1'will have a thickness t of the corrugated core 1'. Since a corresponding step is formed, when a ruled line is formed along this joint portion 1a ', it is difficult to form this ruled line in a straight line, and it is not possible to manufacture a box having a desired shape. Instead, it had the drawback of becoming a box that was easy to deform and weak in strength.

It has a uniform thickness over the entire surface without being subjected to printing, and can be printed beautifully. Further, in a box manufactured using such corrugated board, since the corrugated core 1 is always present in the front-back direction of the corrugated board, there is a case where ruled lines are formed along the joint portions 3 and 4. Also, since the strength of this part can be prevented from decreasing and the surface of the corrugated board can be made a flat surface without any steps, it is possible to form the ruled lines in a straight line reliably, and it is difficult for deformation to occur and it has an excellent shape. is doing.
【００１７】 このように種々の効果を有する本考案に係る段ボールの波型中芯は、その実用 的価値の非常に大きなものである。As described above, the corrugated core of the corrugated board according to the present invention having various effects has a great practical value.
