Description

本発明は、自動製函機での組み立てに対応した構造のプラスチックシートに関する。   The present invention relates to a plastic sheet having a structure corresponding to assembly in an automatic box making machine.

包装ケースに折り曲げ加工されるプラスチックシートとして、図8に断面図で示されているように、シート11の表面に設けられた罫線を形成する凹溝12の底部に、その長さ方向に沿って凹凸を形成し(同図(A))、或いは断続孔を形成し(同図(B))、深さの深い凹溝部13と浅い凹溝部14を交互に設けた構造のものが知られている。   As a plastic sheet that is bent into a packaging case, as shown in a cross-sectional view in FIG. 8, along the length direction, at the bottom of the concave groove 12 that forms a ruled line provided on the surface of the sheet 11. There is known a structure in which irregularities are formed (FIG. (A)) or intermittent holes are formed (FIG. (B)), and deep grooves 13 and shallow grooves 14 are alternately provided. Yes.

従来構造のものは、罫線の底部に凹凸がない構造のものと比較して折り曲げ性が良好であるものの、製函機を用いてシートを組み立てる場合に、シートの材質や厚みなどの条件によっては、曲がり方が不十分でケースを組み立てることができず、例え組み立てることができてもケースが変形することがあった。これと反対に必要以上に曲がると、やはりケースが変形してしまうことがあった。また、シートの折り曲げに伴って凹溝から露出した凹凸部分がささくれ立って、手触りを悪くしたり割れや裂け目ができたりすることがあった。   Although the conventional structure has better bendability than the structure with no irregularities at the bottom of the ruled line, depending on the conditions such as the material and thickness of the sheet when assembling the sheet using a box making machine The case cannot be assembled due to insufficient bending, and the case may be deformed even if it can be assembled. On the other hand, if it bends more than necessary, the case could be deformed. In addition, as the sheet is bent, the uneven portions exposed from the concave grooves are raised up, and the touch may be deteriorated or cracks and tears may be formed.

本発明は従来技術を有するこのような問題点に鑑み、折り曲げ罫線入りのプラスチックシートを自動で組み立てる場合に、不十分な折れ曲がりや曲がり過ぎなどの加工不良を起こすことなく、堅牢且つ綺麗に組み立てることができるようにすることを課題とする。   In view of such problems with the prior art, the present invention assembles robustly and cleanly without causing poor processing such as insufficient bending or excessive bending when a plastic sheet with bent ruled lines is automatically assembled. The challenge is to be able to.

本発明は、折り曲げ罫線となる凹溝内に、その長さ方向に沿って深い凹溝部と浅い凹溝部が設けられた構成を備えた折り曲げ罫線入りプラスチックシートであって、深い凹溝部と浅い凹溝部の境界線が罫線方向に対して傾斜して設けられることを特徴とする折り曲げ罫線入りプラスチックシートを提案する。   The present invention relates to a folded ruled line plastic sheet having a configuration in which a deep groove and a shallow groove are provided along a length direction in a groove that becomes a folding rule, and the deep groove and the shallow groove are provided. A plastic sheet with a folded ruled line is proposed, characterized in that the boundary line of the groove is inclined with respect to the ruled line direction.

なお、深い凹溝部は、シート裏面から適宜な厚みを有する場合と、裏面側に貫通させて開孔とする場合がある。深い凹溝部を開孔とした場合、折り曲げたときに生ずる歪みや弾性力が凹溝の長さ方向に分散し、深い凹溝部に厚みの有る場合よりも折れ曲がり易くなるが、深い凹溝部を開孔とするか厚みが有るようにするかは、前述した如く、加工不良を生じないよう、シートの材質や厚み、凹溝の成形条件などに応じて選定され得る。   The deep groove portion may have an appropriate thickness from the back side of the sheet, or may penetrate through the back side to be an opening. When the deep groove is an open hole, the strain and elastic force generated when it is bent are dispersed in the length direction of the groove and it is easier to bend than when the deep groove has a thickness. As described above, the hole or the thickness may be selected according to the material and thickness of the sheet, the molding condition of the concave groove, etc. so as not to cause processing defects.

また、罫線となる凹溝は、シートの片面に設ける他、シートの両面に設けることができる。シートの両面に設ける場合、一側の面の凹溝が前記の如く構成されていればよい。   Further, the concave grooves serving as ruled lines can be provided on both sides of the sheet in addition to being provided on one side of the sheet. When providing on both surfaces of a sheet | seat, the concave groove of the surface of one side should just be comprised as mentioned above.

また、本発明の包装ケースは、前記各構成のシートを所定の輪郭に打ち抜き、これを罫線に沿って折り曲げ、組み立てることにより得ることができる。   Moreover, the packaging case of this invention can be obtained by punching the sheet | seat of each said structure to a predetermined outline, bending this along a ruled line, and assembling.

なお、本発明が適用されるプラスチックシートとしては、ポリ塩化ビニル、ポリエチレン、ポリプロピレン、ポリエステル、ポリカーボネートなどの単体又は複合シートを用いることができる。シートの厚みは、通常、0.1〜1.0mm程度のものが用いられるが、これに限定されない。   In addition, as a plastic sheet to which the present invention is applied, a single or composite sheet such as polyvinyl chloride, polyethylene, polypropylene, polyester, or polycarbonate can be used. The thickness of the sheet is usually about 0.1 to 1.0 mm, but is not limited thereto.
