Description
第二に、この剥がす形態の封止体が破損と切断されると同時に剥がれることによって一度開封した封止体は再び使用できないようにして外部からの悪意的な行動から保護するためのタンパーエビデントの機能を付与する。
容器入口を密封するために適用される容器封止体であって、
上部層、
前記上部層の下部に構成する下部層、
前記上部層と前記下部層の間には熱接着樹脂による熱接着が行われるように構成した熱接着樹脂層、で構成され、
前記上部層は印刷および熱接着防止のための表面層、
引張強度と硬度を備えた合成樹脂層、を上部から下部に順次構成し、
前記上部層を切断およびパンチング作業により構成した開封タブ、
前記開封タブの一側に構成した開封開始誘導切断線、を形成させ、
前記下部層は酸素または湿気の透過を防止する遮断層と熱接着封止層で構成され、
前記上部層の前記合成樹脂層と前記下部層の前記遮断層を接着させるように構成する容器封止体を提供する。
また、確実に容器封止体が破壊され、この封止体を再び容器に貼ることをできなくすることによりタンパーエビデント機能を付与する。
このために本発明の封止体は開封タブが封止体の上部面にあり、指で開封タブをつまみやすくするために円形や一字形状の比較的大きな開封タブで構成することができる。この開封タブを引いた時少ない力でも開封開始誘導切断線に沿って開封がなされる。
容器入口面にシールされている部分からはイージークリーンピール(Easy clean peel)形態で容器封止体を容器から除去して開封することにより便利な開封のための封止体を提供することに目的がある。
前記上部層10の下部に構成する下部層30、
前記上部層10と前記下部層30の間には熱接着樹脂による熱接着が行われるように構成した熱接着樹脂層20で構成され、
前記上部層は印刷および熱接着防止のための表面層10-a、
引張強度と硬度を備えた合成樹脂層10-cを上部から下部に順次構成し、
前記上部層を切断およびパンチング作業により構成した開封タブ11を示すものである。
前記下部層は酸素または湿気の透過を防止する遮断層30-aと熱接着封止層30-bで構成され、
前記上部層の前記合成樹脂層10-cと前記下部層の前記遮断層と接着させる熱接着樹脂層20で容器封止体を構成する。
前記熱接着樹脂層20は上部層と下部層が2kg/15mmの力で熱接着されるように構成することが好ましい。
ここで前記合成樹脂層10-cと前記遮断層30-aを接着するために熱接着樹脂層20で構成されることが好ましい。
特にポリエステルフィルムが費用と性能の面で優れる。
前記開封タブ11の下部面に前記熱接着樹脂層20に対する離型性を良くするために開封タブ11の下部面にシリコン部500をエンボス処理して上部層10と下部層30をラミネートする過程で前記開封タブ11が前記熱接着樹脂層20により下部層30の上部面と熱接着されることを防止することが好ましい。
前記開封タブの下部面に凹凸部400処理して(鋸波に凹凸部を形成したがいかなる形状でも構わない。)熱接着樹脂層20とラミネートされた時接触面積を少なくして前記開封タブが前記下部層から容易に離脱するように構成する。
開封タブの下部面に凹凸部400の形状にエンボス処理をして熱接着樹脂層20とラミネートされた時接触面積を少なくして前記開封タブ11が前記下部層30から容易に離脱するように構成し、前記熱接着樹脂層20に対する離型性を良くするために凹凸形状にエンボス処理された開封タブの下部面にシリコーン処理をして上部層10と下部層30をラミネートする過程で前記開封タブ11が前記熱接着樹脂層20により下部層30の上部面と熱接着されることを防止して開封タブ11が熱接着樹脂層20からよく分離するようにする。
