【００１０】
【発明の実施の形態】
以下本発明の実施の形態を図面を参照して説明する。
図１は本発明によるファスナーバッグを示し、このファスナーバッグ１は、袋状容器２と、この袋状容器２の内面に溶着手段または接着手段により固着されたファスナー装置３とから構成されている。
【００１１】
上記袋状容器２は、図１および図２に示すように、矩形状に裁断した包材を側縁４ａ，４ｂ同士が背面側で突き合わされるように折り曲げ成形し、側縁４ａ，４ｂ同士をヒートシールして背シール部５を有する筒状体を形成し、この筒状体の上端および下端をヒートシールして上端ヒートシール部６および下端ヒートシール部７を形成することにより作られる。上記包材は、好ましくはラミネートフィルムであるが単体のフィルムであってもよい。
【００１２】
透明性袋状容器２をラミネートフィルムの包材で成形する場合、包材は、厚さ２０〜５０ミクロンの２軸延伸ポリプロピレンフィルムと厚さ２０〜６０ミクロンの無延伸ポリプロピレンフィルムを厚さ２〜３ミクロンのドライ接着層によりラミネートしたラミネートフィルムや、厚さ９〜２５ミクロンのポリエステルフィルムと厚さ２５〜１２０ミクロンの直鎖状低密度ポリエチレンフィルムを厚さ２〜３ミクロンのドライ接着層によりラミネートしたラミネートフィルムや、厚さ９〜２０ミクロンの２軸延伸ナイロンフィルムと厚さ２５〜１２０ミクロンのポリエチレンフィルムを厚さ２〜３ミクロンのドライ接着層によりラミネートしたラミネートフィルムが適当である。
上記包材は、接着剤としてドライ接着層を用いたが、ドライ接着層を厚さ１２〜２０ミクロンのポリエチレン押出し層とすることもできる。
【００１３】
不透明性袋状容器２をラミネートフィルムの包材で成形する場合、包材は、厚さ９〜２５ミクロンのポリエステルフィルムと厚さ６〜３０ミクロンのアルミニウム箔と厚さ２５〜１２０ミクロンの直鎖状低密度ポリエチレンフィルムを厚さ２〜３ミクロンのドライ接着層によりラミネートしたラミネートフィルムや、厚さ９〜２５ミクロンのポリエステルフィルムと厚さ１２ミクロンのアルミ蒸着ポリエステルフィルムと厚さ２０〜６０ミクロンの無延伸ポリプロピレンフィルムを厚さ２〜３ミクロンのドライ接着層によりラミネートしたラミネートフィルムが適当である。
上記包材は、接着剤としてドライ接着層を用いたが、ドライ接着層を厚さ１２〜２０ミクロンのポリエチレン押出し層とすることもできる。
【００１４】
上記ファスナー装置３は、図２に示すように、互いに分離した雄型ファスナー部材８と雌型ファスナー部材９から構成され、雄型ファスナー部材８の基部８ａが袋状容器２の背シール部５の一側に固着され、雌型ファスナー部材９の基部９ａが袋状容器２の背シール部５の他側に固着されている。
【００１５】
上記雄型ファスナー部材８および雌型ファスナー部材９は、たとえば、ポリエチレン、ポリプロピレン、またはこれらの共重合体のようなオレフィン系樹脂材料を押出成形手段により連続的に成形される。雄型ファスナー部材８および雌型ファスナー部材９の嵌合部は、図２では１つであるが、必要に応じて２つ以上てあってもよい。
【００１６】
上記袋状容器２の内面で雄型ファスナー部材８の基部８ａと袋状容器２の背シール部５の間にカットテープ１０が固着されている。このカットテープ１０は袋状容器２を開封するための引き裂き容易手段として作用する。カットテープ１０に長手方向に延びる２つの切り込み線を設け、カットテープ１０の２つの切り込み線により形成される片を引き裂き容易手段として利用することもできる。
上記カットテープ１０は、幅が３〜１５ｍであり、袋状容器２の雄型ファスナー部材８と雌型ファスナー部材９の間で袋状容器２の上端ヒートシール部６から下端ヒートシール部７まで連続して延びている。上端ヒートシール部６および下端ヒートシール部７の少なくとも一方には、カットテープ１０の端部に対応して図示しない略３角形の切欠き線が形成されている。この切欠き線はヒートシール部の一部を切り離してカットテープ把持部を形成する。この把持部はカットテープ１０の端部に一体的に結合されている。
【００１７】
上記カットテープ１０は、図３に示すように、直鎖状低密度ポリエチレン層１１と、ポリエステル層１２と、イージーピール層１３との３層構造である。イージーピール層１３は、たとえば塩素化ポリプロピンやＥＶＡ、あるいはホットメルト層で形成され、剥離強度が２００ｇ／ｃｍ程度になるように設定されている。 また、袋状容器２の包材は、その切断強度をカットテープ１０のイージーピール層１３の剥離強度より高く設定されている。
【００１８】
上記カットテープ１０は、低密度ポリエチレン層とポリエステル層と低密度ポリエチレン層とイージーピール層との４層構造、直鎖状低密度ポリエチレン層とポリエステル層と直鎖状低密度ポリエチレン層とイージーピール層との４層構造、、超低密度ポリエチレン層とポリエステル層と超低密度ポリエチレン層とイージーピール層との４層構造、キャストポリプロピレン層とポリエステル層とキャストポリプロピレン層とイージーピール層との４層構造であってもよい。
【００１９】
つぎに、ファスナーバッグ１の製造方法を説明する。
図１に示す袋状容器２の包材として、自動充填包装機に適用できるように、連続長のラミネートフィルムを袋状容器２の幅と背シール部５の長さの合計長さの２倍の長さに裁断した包材が用いられる。
【００２０】
包材は側縁４ａ，４ｂ同士が突き合わされるように折り曲げ成形されて筒状体を形成する。ついで、連続長のファスナー装置３およびカットテープ１０が筒状体の内部に供給される。この場合、ファスナー装置３は雄型ファスナー部材８と雌型ファスナー部材９を互いに嵌合した状態で供給される。
【００２１】
ファスナー装置３の雄型ファスナー部材８は、筒状体の突き合わされた側縁４ａ，４ｂの一側に配置され、ファスナー装置３の雌型ファスナー部材９は、筒状体の突き合わされた側縁４ａ，４ｂの他側に配置される。
また、カットテープ１０は、雄型ファスナー部材８の基部８ａと雌型ファスナー部材９の基部９ａとの間に配置される。カットテープ１０は、筒状体の一端から他端まで連続して延びるように配置される。
【００２２】
つぎに、筒状体の突き合わせた側縁４ａ，４ｂ同士は、ヒートシール加工されて背シール部５を形成する。これと同時に、雄型ファスナー部材８の基部８ａと雌型ファスナー部材９の基部９ａおよびカットテープ１０は、筒状体の内面に溶着手段または接着手段により固着される。これにより、内面にファスナー装置３とカットテープ１０を固着した両端開口の筒状体が形成される。カットテープ１０の上面に位置するイージーピール層１３は雌型ファスナー部材９の基部９ａに接着される。
【００２３】
つぎに、ファスナー装置３とカットテープ１０を固着した両端開口の筒状体は、下端がヒートシール加工されて下端ヒートシール部６を形成する。そして、上端開口の袋状容器２の内部に上端開口部を通して内容物が充填される。内容物が充填された筒状体は、上端開口端をヒートシール加工することで上端ヒートシール部６を形成する。内容物が充填された袋状容器２は、上端ヒートシール部６とこれに続く包材との間で切断される。
【００２４】
ファスナーバッグ１を開封して内容物を取り出すには、まず、上端ヒートシール部６または下端ヒートシール部７を切欠き線に沿って切断してヒートシール部から分離されるカットテープ把持部を形成する。
【００２５】
ついで、カットテープ把持部を指で挟持し、カットテープ把持部をファスナーバッグ１の面から離れる方向に引き上げる。これにより、カットテープ把持部は、ヒートシール部から分離する。カットテープ把持部をそのままファスナーバッグ１の面から離れる方向に引き上げると、カットテープ把持部にカットテープ１０の端部が結合されているので、カットテープ１０が袋状容器２の雄型ファスナー部材８の基部８ａと雌型ファスナー部材９の基部９ａとの間の部分を切断する。これにより、ファスナーバッグ１が開封され、この開封部を介して内容物を取り出すことができる。
内容物を取り出した後、雄型ファスナー部材８と雌型ファスナー部材９を嵌合することで、ファスナーバッグ１内に残る内容物を密封することができる。
【００２６】
図４は本発明の他の実施の形態のファスナーバッグ１ａを示し、このファスナーバッグ１ａは、図２に示すファスナーバッグ１と比較すると、袋状容器２の構成は同じであるが、ファスナー装置３ａの取付け位置が相違している。
すなわち、上記ファスナーバッグ１ａは、図２に示すファスナーバッグ１の袋状容器２の内面の背シール部５の一側にファスナー装置３ａの雄型ファスナー部材８ａと雌型ファスナー部材９ａを並列配置している。
これにより、ファスナーバッグ１ａは、背シール部５から離れた位置で開封されることになる。
【００２７】
図５は本発明の他の実施の形態のファスナーバッグ１ｂを示し、このファスナーバッグ１ｂは、図２に示すファスナーバッグ１と比較すると、ファスナー装置３の配置は同様であるが、袋状容器２が合掌貼り型袋状容器２であるか封筒貼り型袋状容器２ｂであるかにおいて相違している。
【００２８】
【発明の効果】
以上述べたように本発明によれば、袋状容器を１枚の包材で形成し、袋状容器の一面にファスナー装置を配置し、袋状容器の内面にカットテープを設けたことで、開封および再封が可能でかつ特殊な装置を必要としない一般の自動充填包装機に適用できる。
