【０００１】
【発明の属する技術分野】
本発明は、物品包装用紙器の構造外面などに設ける紙器開封用ジッパーに関する。
【０００２】
【従来の技術】
各種食品類や菓子類、あるいはその他日用品類など各種物品を包装する紙容器の構造外面などに刻切して設けられる紙器開封用の切込線やジッパー（開封帯）には、従来、例えば図５（ａ）〜（ｄ）に示すように、一列に刻切した切込線としての各種パターンがあり、（ａ）は六面体形状の紙容器Ａの構造側板上部の外周面に水平線１とその一端の斜線２との組み合わせによる屈曲線を一列に断続的に刻切した切込線Ｂ、（ｂ）は円筒形状の紙容器Ａの周側板上部の外周面に波形線３をその両端部が互いにオーバーラップするように一列に断続的に刻切した切込線Ｂ、（ｃ）は六角筒形状の紙容器Ａの構造側板上部の外周面に水平線１とその両端の同じ角度の斜線２、２との組み合わせによる屈曲線を一列に断続的に刻切した切込線Ｂ、（ｄ）は六面体形状の紙容器Ａの構造側板上部の外周面に連続波形４を断続的に一列に刻切した切込線Ｂである。
【０００３】
また、例えば図６（ａ）〜（ｅ）に示すように、二列状態に刻切したジッパー（開封帯）としての各種パターンがあり、（ａ）は紙容器の外周面にＹ字形状線５を二列に断続的に同一位相で刻切したジッパーＣ、（ｂ）は紙容器の外周面に水平線１とその一端の斜線２との組み合わせによる屈曲線を二列に断続的に同一位相で刻切したジッパーＣ、（ｃ）は紙容器の外周面に水平線１とその一端の斜線２とその他端の直角に屈曲する垂直線６との組み合わせによる屈曲線を二列に断続的に同一位相で刻切したジッパーＣ、（ｄ）は紙容器の外周面に水平線１とその一端に連結した垂直線７との組み合わせによるＴ字形状線を二列に断続的に同一位相で刻切したジッパーＣ、（ｅ）は紙容器の外周面に水平線１と湾曲形状線８とを二列に断続的にＵ字形状に刻切したジッパーＣである。
【０００４】
これら図５、図６に示した従来の切込線Ｂや帯状のジッパーＣ、特に図６に示した各種パターンのジッパーＣは、その一端部を矢印方向から摘んで引き上げることにより、紙器の構造外面を破断して開封するものであって、その開封操作において一方向に開封し易い方向性を有しており、これらジッパーの矢印側の端部の近傍の容器表面には、矢印を印刷表示したり、「ＯＰＥＮ」の文字を印刷表示して、その開封方向を指示している。
【０００５】
しかしながら、このように容器Ａに開封方向の指示がされていても、不注意で反対方向より開封してしまったり、あるいは幼児や目の不自由な人などは、開封方向の表示の認識が困難な場合があり、このような場合には容器を開封し難いものである。
【０００６】
そこで、開封方向性のない開封用ジッパーとしては、図７（ａ）〜（ｃ）に示すようなものがあり、（ａ）は紙容器の外周面に水平線１とその一端の斜線２との組み合わせによる屈曲線を図示するように二列に断続的に同一位相で刻切したジッパーＣ、（ｂ）は紙容器の外周面に水平線１とその一端の斜線２との組み合わせによる屈曲線を互いに対向するように二列に断続的に同一位相で刻切したジッパーＣ、（ｃ）は紙容器の外周面に凸湾曲線と凹湾曲線とを交互に組み合わせた波形線９を二列に断続的に同一位相で刻切したジッパーＣである。
【０００７】
本発明は、上記のように紙器の開封操作における方向性を解消することを課題として、ジッパーの両端部のいずれより開封操作を開始しても、開封がスムーズにできるようにすることにある。
【０００８】
【課題を解決するための手段】
本発明は、開封方向に沿って規則的に同一位相で二列に断続する長い直線切込線１１と、該各々長い切込線１１の両端部に該切込線１１の開封方向に直角な平行に離間対向する短い直線切込線１２、１２を備え、前記各々長い直線切込線１１の長さをａ、平行に離間対向する前記各々短い直線切込線１２、１２の離間距離をｂ、前記長い直線切込線１１から両側に直角方向に張り出した短い直線切込線１２の張り出し長さをｃとしたとき、長い直線切込線１１の長さａは、短い直線切込線１２の離間距離ｂの２〜３倍長く、ｂ≧ｃの関係が成立するように設定されていることを特徴とする紙器開封用ジッパーである。
【０００９】
【発明の実施の形態】
本発明の紙器開封用ジッパーを、実施の形態にしたがって以下に詳細に説明すれば、図１は、紙器Ａ（紙容器）の上面板に形成した本発明の紙器開封用ジッパーの平面図であり、開封方向に沿って規則的に同一位相で二列に断続する長い直線切込線１１が刻切されている。
【００１０】
そして、該各々長い切込線１１の両端部に、開封方向に直角な短い直線切込線１２が刻切されて、その二列の切込線１１、１２の列の間にジッパーＣが形成されている。
【００１１】
上記各々長い切込線１１の両端部に刻切した隣接対向する長い切込線１１に対して直角方向のそれぞれ短い切込線１２、１２は、互いに平行に離間しており、その離間部分が開封される前の繋ぎ部１２ａとなっている。
【００１２】
本発明の上記ジッパーＣは、紙器Ａを構成する構造体の各構成板、例えば、上面板、側面板（前面板、背面板、左右側面板など）、あるいは底面板などのいずれかに形成され、例えば、構成板のうち、側面板には、その一部の側面板若しくは全部の側面板に全周に亘って連続して設けられる。
【００１３】
また、上記ジッパーＣの両端部を形成するそれぞれ長い切込線１１の外端には開封方向に直角な短い直線切込線１２は刻切されず、該ジッパーＣの両端部は、二列の開封方向の切込線による摘まみ開封用タブＣ1 、Ｃ1 となる。なお、該開封用タブＣ1 、Ｃ1 の外端部は、必要に応じて、構成板（上面板）の端縁より僅かに突出するように形成されていてもよいし、開封用タブＣ1 、Ｃ1 の外端部を開封操作前まで構成板（上面板）に対して繋ぐための僅かな繋ぎ部１１ａ（未切込部）が形成されていてもよい。
【００１４】
本発明の上記ジッパーＣは、図１の右端のタブＣ1 又は左端のタブＣ1 の両方より開封でき、タブＣ1 を指で摘んで立ち起こし、そのまま上方に引っ張ることにより、開封方向の切込線１１による開封方向に向かう直線的な分断力が作用して、まず最初の繋ぎ部１２ａを破断し、続いて、次の開封方向の切込線１１による開封方向に向かう直線的な分断力によって、次の繋ぎ部１２ａを破断し、ジッパーＣは帯状となって順次繋ぎ部１２ａを破断して、紙器Ａを開封する。
【００１５】
図２は、本発明のジッパーＣの部分拡大平面図であり、長い切込線１１の長さをａ、平行に離間対向する短い切込線１２、１２の離間距離をｂ、長い切込線１１から両側に直角方向に張り出した短い切込線１２の張り出し長さをｃ（短い切込線１２の長さ２ｃ）としたときに、ａ＞（２ｂ〜３ｂ）、ｂ≧ｃの関係が成立するように設定することが適当である。
【００１６】
例えば、一例として、
長い切込線１１の長さａ＝７ｍｍ
短い切込線１２の長さ２ｃ＝４ｍｍ
短い切込線１２、１２の離間距離ｂ＝２〜２．５ｍｍ
に設定される。
【００１７】
なお、上記のような数値に設定した場合の開封時の開封に必要なジッパーＣの引っ張り力は、通常のカートン用紙（紙厚；０．２ｍｍ〜０．２５ｍｍ程度）を使用した場合には、３５０ｇ／ｍ2 前後の加圧力に相当する引っ張り力となり、また、離間距離ｂの大きさに比例してジッパーＣの引っ張り力は大きくなる。
【００１８】
図３は、紙器Ａの上面板２１に本発明のジッパーＣを刻切した一実施の形態を示す斜視図であり、紙器Ａは、上面板２１、四側面板２２、２３、２４、２５、底面板２６により構成されて、ジッパーＣの両端部には、開封方向の表示をしなくてもよいが、図示するように矢印などの開封方向の表示１３をしてもよい。
【００１９】
図４（ａ）は、紙器Ａの上面板２１に本発明のジッパーＣを刻切した他の実施の形態を示す斜視図であり、紙器Ａは、ジッパーＣの長手方向両端部に相当する上面板２１の両端縁２１ａ、２１ａが、Ｖ字型に切り込まれた形状の上面板２１と、四側面板２２、２３、２４、２５と、底面板２６とにより構成されている。
【００２０】
上記紙器Ａの構造において、図４（ｂ）に示すように、ジッパーＣを刻切した上面板２１の上面と、該上面板２１の下面に折り込まれた側面板２４の上部に連設した折り込みフラップ板２４ａの上面との間に、僅かな段差ｄ（例えば１ｍｍ程度）を付けた構造の紙器Ａの場合は、上面板２１の上面と同一面の、両端タブＣ1 、Ｃ1 と、折り込みフラップ板２４ａの上面との間には段差が形成されて、紙器ＡにおけるタブＣ1 の位置を、感触により正確に確認できる。
【００２１】
【発明の効果】
本発明の紙器開封用ジッパーは、ジッパーの両端部のいずれの端部より開封操作を開始しても開封がスムーズにでき、紙器の開封操作におけるジッパーの開封方向性を解消でき、従来の開封方向性のあるジッパーのように不注意による開封し難さの発生が解決されて、幼児や目の不自由な人なども、開封方向の表示の認識をしなくても、開封用ジッパーの存在位置を確認するだけで、いずれの方向よりジッパーを開封開始してもスムーズに開封することができる効果がある。
