Description

【０００１】
【発明の属する技術分野】
本願の発明は、中空の容器本体の口頸部に嵌着せしめて密封する不正開封防止機能を備えた蓋体を装着した容器に於いて、使用後に空になった容器を廃棄する際に、前記蓋体を簡単に容器本体から分離できるようにして、分別処理を容易となした密封蓋体に係わるもので、中でも、容器本体の口頸部に嵌着せしめる中蓋の外周に外蓋を嵌合して打栓可能に形成すると共に、中蓋部に分離用のプルリングを設けて、蓋体を容器本体の口頸部から簡単に分離できるようにした不正開封防止機能を備えた密封蓋体に関するものである。
【０００２】
【従来の技術】
醤油や味醂等の調味料、あるいは、ソースやドレッシング、その他の飲食に供する液状物を収容した容器として、従来から一般に広く使用されているものは、熱可塑性合成樹脂をブロー成形した中空容器本体の口頸部に、開口可能に形成された密封用の中蓋が嵌着、固定された上から外蓋が被着されたものである。
そして、これらの密封容器は、容器本体部分はポリエチレンテレフタート等の耐熱性を有する硬質の高級樹脂を用いて成形されいて、また、蓋部はポリエチレン等の軟質の汎用性樹脂を用いて成形されるというように、容器本体と蓋体とはその機能に応じた異質の樹脂を用いて形成されていることが多い。
【０００３】
また、上記のような飲食に供する液状物を収容した各種の密封容器に於いては、容器本体内への異物の混入防止や容器本体内の内容物の品質保持のため、あるいは、不心得者による不正な開封を防止するためには、容器の開口部を密閉した中蓋を容器本体の口頸部から簡単には抜き取れないようにすることが必要条件であることから、内容物を注出するには、中蓋の一部を破断しなければ開封できない構造にした密封方法が採られている。
【０００４】
従って、上記のような構造をした中蓋が用いられている密封容器は、使用済みとなって廃棄される際に、中蓋がついたままの状態で廃棄されているのが現状であるから、廃棄物として回収されたこのような容器を資源として再生利用するには、容器本体とは異質材の中蓋は刃物等で切断して除去しなければならないので、容器本体と中蓋とを分別するのに手間がかかり、再生コストの点から再生利用するのには不向きである。
【０００５】
ところで、近年になって容器リサイクル法等が施行されたことにより、合成樹脂製容器も資源として再利用されるようになってきており、そのために廃棄時には材質の異なる中蓋を容器本体から簡単に外せるようにした密封蓋体を用いた注出容器が望まれるようになっている。
そのような中で、中蓋を容器本体から簡単に外せるようにした密閉蓋体を用いた注出容器として、特開平１０―２９１５５４号や特開平１１―３２１９１３号公報その他に見られるように、各種の形状をした密封容器が提案されている。
【０００６】
これら従来の分離可能な密封蓋体を用いた注出容器は、図７に示すように、中空容器本体３１の口頸部３１ａに中蓋３２の嵌合筒部３２ａを嵌合して、該筒部の凸部と口頸部の凹部との係合により、中蓋３２が容器本体の口頸部から簡単には外れないよう強く保持された構造にしたものである。
そして、前記中蓋３２は、嵌合筒部３２ａの外周壁に間隔を隔てて縦方向の平行な弱め線３３を設けると共に、該筒部の周りに適数の破断片を介して環状に設けた引き抜き用の環状把手３４を、前記弱め線の引き裂き部に連結片３２ｂを介して一体に連結して、引き抜き可能に形成されている。
【０００７】
上記のように形成された密封中蓋３２を設けた注出容器は、空になって廃棄する際に、容器本体３１から前記中蓋３２を取り除くには、図８に示すように外蓋を取り除いてから、中蓋の嵌合筒部３２ａの外周に設けられた引き抜き用の環状把手３４を引き起こしてから、該把手に指先を掛けて上方へ引上げると、中蓋の嵌合筒部が前記弱め線に沿って引き裂かれる。
このようにして嵌合筒部３２ａの弱め線が破断された前記中蓋３２は、容器本体の口頸部３１ａに保持されていた力が弱くなり、環状把手３４を指先で引っ張ることにより中蓋３２を容器本体の口頸部から簡単に外すことができるので、簡単に分別して廃棄することができる。
【０００８】
しかし、上記したような密封容器は、切除可能な閉板（盲板）３５を中央部分に形成した中蓋３２を容器本体の口頸部３１ａに嵌着して開口部を密封して、その上からキャップ状の外蓋３６を嵌合せしめて密閉したものであり、不正開封防止機能は、中蓋３２に形成された切除可能な閉板３５だけで果たすようになっているので、外蓋３６を開けて中蓋部分を覗いて確認しない限りは、容器が開封されたものなのか、または、非開封のままなのかを判断することができない。
【０００９】
そこで、上記のような切除可能な閉板を形成した中蓋を用いた密封容器に於いて、外蓋を開けて中蓋の状態を確認しなくても、外蓋部分を見るだけで開封されたか否かを確認できるようにした蓋体により密封されてなる液体注出容器が、特開平１１−１５７５６０号や特開２００１−３３５０５５号公報等に提案されている。
これらの密封容器の蓋体は、開口部に嵌着、密封された中蓋の上から被せて密閉する外蓋が、中蓋の上部周壁に嵌着するカップ状の外蓋本体部と、該外蓋本体部の下端部に複数個の連結片を介して破断可能に連結された中蓋の下端部の外周面に嵌合した外蓋筒部とから形成されている。
【００１０】
このような外蓋からなる蓋体は、外蓋筒部が中蓋の外周面を覆っていて、外蓋を開けない限り中蓋に指を触れることができないので、開封しようとして外蓋の外蓋本体部を掴んで開蓋方向に回転させると、外蓋本体部と外蓋筒部との間の連結片が全て捻じ切れて、外蓋の外蓋本体部が外蓋筒部から分離して、外蓋筒部だけが中蓋の下端部の外周面に嵌合した状態のまま残って、連結片の切断痕が現れることになる。
従って、このような蓋体を用いた注出容器は、外蓋を一見するだけで不心得者が容器を不正に開封した事実は露顕するので、不正開封を防止する機能を発揮することができて便利である。
【００１１】
そして、上記のようにして容器本体の口頸部に残った外蓋の外蓋筒部は、内容物を使い切った後で、ねじ込み方向に強力に螺合せしめることにより、中蓋は上向きの強い力を受けて口頸部から離脱されるので、容器本体の口頸部から分離可能となって、容器本体とは別にして廃棄することができる。
しかし、このような蓋体を設けた容器は、中蓋を容器本体の口頸部から分離するのに強い捻じり力を要するので、指先の力が弱い子供や老人にとっては簡単にはできないので、指先の力が弱い人手であっても容易に分離することがでるようにした中蓋を有する密封容器の出現が望まれる。
【００１２】
【発明が解決しようとする課題】
本願の発明は、上記した切除可能な閉板部を設けた中蓋からなる密封蓋体と、簡単に破断するように形成した密閉蓋体とのそれぞれの良い点を組み合わせることにより、不正開封防止機能を備えた分別処理が容易な密封蓋体を創案したものである。
液状物を収容する中空容器の口頸部に嵌着された切除可能な閉板部を設けて形成した中蓋に、容器本体から分離するための引き抜き用の環状のプルリングを設けて、中蓋が嵌合、固定されている部分を容器本体から簡単に外すことができるようにすると共に、開閉自在な蓋部である外蓋本体部と外蓋筒部とを破断可能に連結した外蓋を前記中蓋に被着せしめて蓋体を形成して、外蓋の外蓋本体部を開封したら破断された痕跡が残るように構成すると共に、容器本体の口頸部から蓋体を簡単に分離することができるように構成して、不正開封防止機能を備えると共に蓋体と容器本体とを簡単に分別処理を可能にした密封蓋体を提供することを目的とする。
【００１３】
【課題を解決するための手段】
本願発明は、各種の液状物を収容した容器本体の開口部を密閉する密封蓋体を、容器本体の口頸部に嵌着して密封する切除可能な閉板部を設けて、且つ、引き抜き可能に形成した中蓋と、該中蓋を覆うように被着して密閉する蓋部が容易に破断可能に形成された外蓋とから構成して、前記外蓋を破断して開けることなしには中蓋を開封できないような二重構造にした不正な開封を防止できる蓋体に形成する。
【００１４】
容器本体の口頸部に嵌合、密着して開口部を密封する前記中蓋を、容器本体の口頸部に嵌合する内外筒部と、該内外筒部を連結する接続部に立設した円筒壁と、該円筒壁の内面に連設した注出筒と破断可能な閉板とから密封可能に形成すると共に、前記接続部に環状体の一部が連結されて、前記円筒壁を囲むようにして設けたプルリングを引き起こし可能に形成する。
また、容器本体の口頸部に嵌着した中蓋を覆って被着する前記外蓋を、中蓋の円筒壁の外周面に螺合されると共に前記プルリングを覆う溝部が形成されてなるカップ状の外蓋本体部と、該外蓋本体部の下端部に切離し可能に接続されて、中蓋の外筒部の外周面に嵌合される外蓋筒部とから形成する。
そして、前記中蓋に前記外蓋を被着せしめて、不正開封防止機能を備えた蓋体を容器本体から簡単に分別処理を可能となした密封蓋体を形成する。
【００１５】
【発明の実施の形態】
中空の容器本体の口頸部３に嵌合する内筒部７ａと外筒部７ｃを連結した接続部７ｂに立設した円筒壁９の内面に連設した内溶液の注出筒１１と破断可能な閉板１２とを設けると共に、前記円筒壁９を囲むようにしてプルリング１７を設けて、液状物を収容する容器本体２の口頸部３に嵌合可能な中蓋４を形成する。
また、前記中蓋４の円筒壁９の外周面に螺合すると共に前記プルリング１７を覆うように形成されたカップ状の外蓋本体部２１と、中蓋４の外筒部７ｃの外周面に嵌合する外蓋筒部２３とを破断可能な連結片２２により連結して、前記中蓋４を覆うように被着する外蓋５を形成する。
【００１６】
そして、前記中蓋４の上に前記外蓋５を被着せしめて、前記外蓋本体部２１を中蓋４の円筒壁９の外周面に螺合すると共にプルリング１７を外蓋本体部２１の環状溝２５内に収容して、且つ、前記外蓋筒部２３を中蓋４の外筒部７ｃに嵌合、固定して、中蓋４に外蓋５が一体的に合体された不正な開封を行うことができない密封蓋体を形成する。
このように形成された密封蓋体を、液状の内容物が収容された容器本体２の口頸部３に嵌着せしめて、容器の開口部を密封した不正開封を防止する機能を備えた液体注出容器１を形成する。
【００１７】
このように形成された液体注出容器から内容液を注出しようとして、外蓋５の蓋部である外蓋本体部２１を掴んで開蓋方向に回動すると、外蓋本体部２１と外蓋筒部２３を連結した連結片２２が破断されて、外蓋本体部２１が除かれて中蓋４が現れると同時に、開封された外蓋には連結片２２の破断痕が残される。
そこで、前記中蓋４の摘み片１９に指先を掛けて引き上げると、閉板１２が弱め線に沿って切除されて注出口が開口するので、容器を手中に持って傾けることにより内容液が注出可能となる。
【００１８】
そのようにして、使用済となった空の液体注出容器１を廃棄する時には、外蓋５の前記外蓋本体部２１を回動せしめて中蓋の円筒壁９から分離して、プルリング１７が露出した状態にしてから、外蓋５の前記外蓋筒部２３を破断せしめた後に、前記プルリング１７を摘んで上方へ引き上げて中蓋４を容器本体２の口頸部３から分離せしめて、容器本体部分と蓋体部分とが分別された状態にしてから廃棄する。
【００１９】
【実施例】
以下に、本願発明の不正開封防止機能を備えた液体注出容器の密封蓋体について、最適な一つの実施例に基づいて、図面を参照しつつ詳細に説明する。
本願発明は、液状物を収容する容器本体２を、ポリエチレンテレフタート等の耐熱性を有する熱可塑性合成樹脂のブロー成形により成形すると共に、該容器本体２の口頸部３に嵌着する中蓋４および該中蓋に被着される外蓋５とからなる不正開封防止機能を有する密封蓋体を、ポリエチレン等の軟質の熱可塑性合成樹脂の射出成形により成形したものを、図６に示すように、ソースや醤油その他の液状の内容物を収容した前記容器本体の口頸部に、前記密封蓋体を嵌合、固定して、液体注出容器１を構成したものである。
【００２０】
前記した中蓋４は、図２および図６に示すように、容器本体２の口頸部３に嵌合する内外筒部からなる嵌合筒部７と、該嵌合筒部７の接続部に立設して外周面に外蓋５を螺合するための雄ネジ８が形成された円筒壁９とからなる段状をした筒状体に形成されて、該段状の筒状体の内寄りに立設した前記円筒壁９の上端内周面に連続して上方に拡開した筒状の注出筒１１と、該注出筒の開口部を閉塞する切除可能な閉板（開口用の盲板）１２とから形成されている。
【００２１】
そして、中蓋４の前記嵌合筒部７は、円筒壁９と同一径をして容器本体２の口頸部３の内面に嵌合する内筒部７ａと、該内筒部７ａから外側に延びるフランジ状をした接続部７ｂと、該フランジ状の接続部７ｂから垂設して容器本体２の口頸部３の外周面に係合する外筒部７ｃとから逆Ｕ字をした環状溝に形成されて、図３に示すように、外筒部７ｃの先端部に係合突起１３が設けられると共に、前記フランジ状の接続部７ｂの外寄りには中蓋４を分離するためのプルリング１７が円筒壁９を囲むように設けられている。
【００２２】
上記のように形成された中蓋４は、内容物が収容された容器本体２に打栓されると、図６に示すように、嵌合筒部７が容器本体２の口頸部３に嵌着されて、口頸部３の外周面に設けられた環状の係合凹部６に外筒部７ｃの内周面に設けられた係合突起１３が係合して、容器本体２の開口部は中蓋４により完全に密封された液体注出容器１が形成される。
その際、図２に示すように、前記中蓋４を、前記外筒部７ｃの外周面に複数の切り筋（筋目）１４が間隔をおいて該外筒部７ｃ下端から縦方向に設けられた状態にしておけば、打栓を行うのが容易になる。
【００２３】
また、前記係合突起１３を中蓋の外筒部７ｃの内面にアンダーカットを設けて、全周面に環状に係合突起１３を形成する代わりに、図３に点線で示すように、係合突起１３ａを間欠的に形成することも可能であり、また、間欠部分を断続的に複数形成しても良い。
このようにして係合突起１３ａを間欠的に設けた場合には、プルリング１７を引っ張って中蓋４を容易に引き抜くことができて、更に、打栓も容易に行うことができるが、その際に、プルリング１７が嵌合筒部７に連結されている部分の下方に間欠部が存在するように形成しておけば、外蓋筒部２３が破断された後の中蓋の外筒部７ｃが変形し易くなって、一層効果を高めることができる。
【００２４】
また、前記外蓋５は、中蓋４の円筒壁９の外周面に形成された雄ネジ８に螺合されるように内周面に雌ネジ２０が形成された外蓋本体部２１と、中蓋４の嵌合筒部７の外筒部７ｃに嵌合して固定される外蓋筒部２３とから形成されて、前記外蓋本体部２１の下端部と外蓋筒部２３の上端部との間は、周方向に間隔をおいて形成された破断可能な複数の小さな連結片２２により一体に連結されていて、外蓋本体部２１が開蓋方向に回動されると、連結片が簡単に破断されて蓋部である外蓋本体部２１が外蓋筒部２３から切り離されるように形成されている。
【００２５】
そして、前記外蓋本体部２１の下端部の外周面に同心状に設けられた断面逆Ｌ字状をした張出部２４に、中蓋４に設けられた前記プルリング１７を覆って外部と遮断する環状溝２５が形成されて、不心得者により中蓋４が不正に外されるのを防止している。
また、前記外蓋筒部２３は、図１に示すように、廃棄する際に容易に破断できるようにするために、壁面には一本のスリットまたはミシン目等からなる弱め線２６が縦方向に設けられると共に、下端部には弱め線２６に接して破断用の摘み片２７が突出して設けられている。
【００２６】
更に、前記外蓋５の外蓋本体部２１は、その天板部２１ａの内面に注出筒１１の内壁に密着するように環状突起２８が設けられていて、蓋部である外蓋本体部２１が中蓋４に被着されて円筒壁９に螺合、固定されると、注出筒１１の開口部を密閉して内容液が流出しないように形成されている。
【００２７】
このように形成された中蓋４と外蓋５とは以下のように合体されて、容器本体２の口頸部３に装着可能にした密封蓋体に形成されて、内容物を収容した容器本体２の口頸部３に嵌着して液体注出容器１が構成されるが、本願の発明は、外蓋５を中蓋４に装着する手段としては、上記したような中蓋４の雄ネジ８と外蓋５の雌ネジ２０とを螺合する方法による以外にも、外蓋と中蓋とを簡単に嵌合して合体することができる適当な方法を採用してもよい。
【００２８】
上記のようにして、図２に示すような形状に成形された中蓋４に対して外蓋５を被せて、外蓋５の外蓋筒部２３を中蓋４の外筒部７ｃに被着せしめて、中蓋４のフランジ状の接続部７ｂに設けられたプルリング１７を外蓋５の環状溝２５に収容可能にしてから、外蓋５を回動せしめて中蓋４の円筒壁９に外蓋５の外蓋本体部２１を螺合すると、外蓋５が回動しながら降下して中蓋４の外筒部７ｃの外周面に外蓋５の外蓋筒部２３の内周面が嵌合されて、外蓋の外蓋本体部２１に設けられた環状溝２５で中蓋４の前記プルリング１７が覆われる。
そして、前記外蓋５の外蓋本体部２１が中蓋４の円筒壁９に螺合、固定されると、図３に示すように、中蓋４の注出筒１１の先端が外蓋５の外蓋本体部２１の天板部２１ａ内面の環状突起２８に密着して固定された状態になり、外蓋５と中蓋４とが合体された密封蓋体が形成される。
【００２９】
このようにして形成された密封蓋体が、液状の内容物を収容した容器本体２の口頸部３に打栓されると、前記中蓋４の外筒部７ｃの下端部面に設けられた切り筋１４部分が少しばかり拡がるように弾性変形して、外筒部７ｃの下端部の内径が一時的に拡大するので、外筒部７ｃの先端部に設けられた係合突起１３が、容器本体２の開口縁部を乗り越えて口頸部３の係合凹部６に係合される。
この時、前記中蓋４の外筒部７ｃは、外蓋５の外蓋筒部２３に密着して覆われているので、外筒部７ｃの下端部の切り筋１４部分が少しばかり拡がっても、前記外蓋筒部２３により締めつけられて破断するようなことはない。
このようにして容器本体２の開口縁部を乗り越えた中蓋４の外筒部７ｃは、前記切り筋１４部分は元の状態に復帰して、外筒部７ｃの下端部の内径が縮小するので、中蓋４の嵌合筒部７が容器本体２の口頸部３に強く嵌合、固定されて、図６に示すように、中蓋４が容器本体２の口頸部３から容易に分離できないように密封された蓋体が嵌着された液体注出容器１が構成される。
【００３０】
上記のように構成された液体注出容器１が、商品として出荷された後に、その流通過程に於いて、不心得者が外蓋５を悪戯心で開けようとして外蓋５の外蓋本体部２１を摘んで回動すると、外蓋本体部２１と外蓋筒部２３との間を結合していた複数の連結片２２が全て捻じ切られるので、不正を行った後で元に戻しても、外蓋５が開けられた事実は一目で発見できて、不正開封された商品が人手に渡ることは防止できる。
また、本願発明の蓋体を用いた液体注出容器１は、外蓋５の外蓋筒部２３により中蓋４の嵌合筒部７の外筒部７ｃが覆われていて、中蓋４を不正に容器本体２の口頸部３から不正に外すことは不可能であるから、この点からも不正開封を防止することができる。
【００３１】
上記のように構成された後で、正常な商品として小売店から消費者が購入した液体注出容器１を、消費者が開封して使用する場合には、図１に示すように、外蓋５の外蓋本体部２１を摘んで矢印方向に回動せしめると、外蓋本体部２１と外蓋筒部２３との間を連結した複数の連結片２２が全て捻じ切られて、外蓋本体部２１は中蓋４の円筒壁９から分離可能になる。
そこで、外蓋本体部２１を中蓋４と容器本体２から完全に分離すると、中蓋４の注出筒１１内の切除可能な閉板１２が現れると同時に、外蓋５の外蓋筒部２３は中蓋４の嵌合筒部７の外筒部７ｃに嵌合したまま残されることになる。
【００３２】
上記のようにして外蓋５の外蓋本体部２１を中蓋４から完全に分離した後で、消費者が、液体注出容器の開口部を密閉していた中蓋４の注出筒１１内にある環状の摘み片１９を指先で摘んで引張り上げると、注出筒１１の内壁面に連結されていた閉板１２は破断可能にした弱め線１８に沿って切除されて、中蓋４の注出筒１１に内溶液を注出可能にした開口が形成される。
【００３３】
上記のようにして中蓋４の注出筒１１の注出口が開口された容器本体２を手に持って傾ければ、中蓋４の注出筒１１の先端から内容物を外部に注出して使用することができる。
このようにして使用した後に、外蓋５の外蓋本体部２１を再び中蓋４に被着せしめて円筒壁９に螺着すれば、外蓋本体部２１内面の環状突起２８が注出筒１１の内面に密着するので、中蓋４の開口部を再密封することができる。
【００３４】
このようにして使用するうちに、容器本体２内の内容物の残量が無くなって、容器を廃棄することになった場合には、図１に示したように、外蓋５の外蓋本体部２１を中蓋４の円筒壁９から完全に分離して、中蓋４のプルリング１７を外部に露出させた状態にした後で、図４に示すようにして、外蓋５の外蓋筒部２３に設けられた摘み片２７を摘んで矢印方向に引っ張ると、外蓋筒部２３は容易に切除できるように設けられた弱め線２６に沿って破断されるので、中蓋４を容器の口頸部３に固定していた拘束力がなくなる。
【００３５】
そこで、中蓋４の円筒壁９の外側のプルリング１７を摘んで、図５に示すように、矢印方向に引き起こしてから、該プルリングに指先を掛けて引張り上げると、中蓋４の外筒部７ｃの切り筋１４部分が緩んで、口頸部３の係合凹部６に係合されていた外筒部７ｃの係合突起１３がアンダーカット面に沿って簡単に抜け出るので、中蓋４の全体を容器本体２の口頸部３から労せずに引き抜いて分離することができる。
【００３６】
このようにして、容器本体２の口頸部から異質の材料である外蓋５の外蓋本体部２１と外蓋筒部２３および中蓋４が分離されて、容器本体と蓋体とが別々に分けられた状態にして廃棄される容器は、分別回収が簡単にできるので、従来のように容器を回収した後で分別処理をする必要がなくなり、容器の再生処理が一層容易になって、再生のための費用を低減させることができる。
【００３７】
【発明の効果】
以上説明したように、破断して開口する閉板を設けた密封中蓋に開封動作により簡単に破綻される外蓋を被着せしめて一体に結合して、中空容器本体の口頸部に嵌着、固定可能に形成した本願発明の密封蓋体は、二重に不正開封防止機能を備えたものであるから、このような密封蓋体を装着した注出容器が不正に開封された場合には、従来の蓋体のように中蓋を見なくても、外蓋を見るだけで不正開封を確認することが可能である。
【００３８】
また、容器本体の口頸部に嵌着、固定された中蓋を口頸部から引き抜いて分離するために、中蓋の円筒壁の外周部に設けられた環状のプルリングを、外蓋の外蓋本体に形成した環状溝により覆って遮断したので、プルリングが不心得者により引張られて、中蓋が外蓋と共に容器本体から不正に外されるのを防止することができる。
【００３９】
そして、本願発明の密封蓋体は、中蓋の筒部の下端部に形成された切り筋部分が外蓋の外蓋筒部により覆われているので、蓋体を容器の口頸部に打栓する際に、中蓋を破損させることがないばかりか、中蓋を容器本体の口頸部から不正に外すことも防止することができて、更には、外蓋の外蓋筒部を簡単に切除することができて、外蓋筒部が除かれた中蓋は、プルリングを引っ張ることにより簡単に口頸部から引き抜いて分離することができるので、容器本体と蓋体とを分別処理するのが容易となり、容器の再生利用を効率良く行うことができる。

BACKGROUND OF THE INVENTION
The invention of the present application is a container equipped with a lid with a tamper-evident prevention function that is fitted and sealed to the mouth and neck of a hollow container body, and when discarding a container that is empty after use, The lid body can be easily separated from the container main body, and is related to a sealing lid body that facilitates the separation process.In particular, an outer lid is attached to the outer periphery of the inner lid that is fitted to the mouth and neck of the container main body. A sealing lid with an anti-tampering function that is formed so as to be able to be plugged by fitting, and a separation pull ring is provided in the inner lid so that the lid can be easily separated from the mouth and neck of the container body It is about the body.
[0002]
[Prior art]
As a container that contains seasonings such as soy sauce and miso, or liquids for sauces, dressings, and other foods and drinks, those that have been widely used in the past are hollow container bodies made of blow-molded thermoplastic synthetic resin. A sealing inner lid formed so as to be openable is fitted and fixed to the mouth and neck, and the outer lid is attached from above.
In these sealed containers, the container body is molded using a heat-resistant hard high-grade resin such as polyethylene terephthalate, and the lid is molded using a soft general-purpose resin such as polyethylene. As described above, the container main body and the lid are often formed using a different kind of resin according to the function.
[0003]
Also, in various sealed containers that contain liquid materials for food and drink as described above, to prevent foreign substances from entering the container body, to maintain the quality of the contents in the container body, or In order to prevent unauthorized opening of the container, it is a necessary condition that the inner lid with the container opening sealed cannot be easily removed from the mouth neck of the container body. In order to take out, a sealing method is adopted in which the inner lid cannot be opened unless a part of the inner lid is broken.
[0004]
Therefore, since the sealed container in which the inner lid having the above-described structure is used is disposed of in a state where the inner lid remains attached when it is used and discarded. In order to recycle such containers collected as waste as resources, the inner lid of the foreign material must be cut and removed with a blade etc. Sorting takes time and is not suitable for recycling from the viewpoint of reproduction cost.
[0005]
By the way, with the recent implementation of the Container Recycling Law, synthetic resin containers have come to be reused as resources. A dispensing container using a sealed lid that can be removed is desired.
In such a situation, as seen in JP-A-10-291554, JP-A-11-321913 and others, as a dispensing container using a sealed lid that allows the inner lid to be easily removed from the container body, Various types of sealed containers have been proposed.
[0006]
As shown in FIG. 7, these conventional dispensing containers using separable sealing lids are fitted with a fitting cylinder portion 32 a of the inner lid 32 on the mouth neck portion 31 a of the hollow container body 31, By engaging the convex portion of the tube portion and the concave portion of the mouth and neck portion, the inner lid 32 is strongly held so as not to be easily detached from the mouth and neck portion of the container body.
The inner lid 32 is provided with a longitudinal parallel weakening line 33 at an interval on the outer peripheral wall of the fitting cylinder portion 32a, and is provided annularly around the cylinder portion with an appropriate number of broken pieces. The pulling-out annular handle 34 is integrally connected to the tearing portion of the weakening line via a connecting piece 32b so as to be pulled out.
[0007]
In order to remove the inner lid 32 from the container body 31 when the dispensing container provided with the sealed inner lid 32 formed as described above is emptied and discarded, an outer lid is used as shown in FIG. After the removal, the annular handle 34 for pulling provided on the outer periphery of the fitting tube portion 32a of the inner lid is raised, and when the fingertip is hung on the handle and pulled upward, the fitting tube portion of the inner lid is moved. Torn along the weakening line.
In this way, the inner lid 32 in which the weakening line of the fitting tube portion 32a is broken is weakened in the force held by the mouth / neck portion 31a of the container body, and the inner lid 32 is pulled by pulling the annular handle 34 with a fingertip. Since 32 can be easily removed from the mouth and neck of the container body, it can be easily separated and discarded.
[0008]
However, the sealed container as described above has an inner lid 32 formed with a resectable closing plate (blind plate) 35 formed in the center portion thereof, fitted to the mouth and neck portion 31a of the container body, and the opening is sealed. The cap-shaped outer lid 36 is fitted and sealed from above, and the function of preventing unauthorized opening is performed only by the resectable closing plate 35 formed on the inner lid 32. It is impossible to determine whether the container has been opened or remains unopened unless the container is opened and the inner lid portion is checked.
[0009]
Therefore, in the sealed container using the inner lid formed with the removable closing plate as described above, it is opened only by looking at the outer lid portion without opening the outer lid and checking the state of the inner lid. Japanese Patent Application Laid-Open No. 11-157560 and Japanese Patent Application Laid-Open No. 2001-335555 propose a liquid dispensing container that is sealed with a lid so that it can be confirmed whether or not it has been.

[0010]
A lid made of such an outer lid has an outer lid cylinder portion covering the outer peripheral surface of the inner lid, and a finger cannot touch the inner lid unless the outer lid is opened. When the lid body is gripped and rotated in the opening direction, all the connecting pieces between the outer lid body and the outer lid cylinder are twisted off, and the outer lid body of the outer lid is separated from the outer lid cylinder. Thus, only the outer lid cylinder part remains in a state of being fitted to the outer peripheral surface of the lower end part of the inner lid, and a cut mark of the connecting piece appears.
Therefore, the dispensing container using such a lid body can exhibit the function of preventing unauthorized opening because the fact that an unskilled person opened the container illegally is revealed just by looking at the outer lid. And convenient.
[0011]
Then, the outer lid cylinder portion of the outer lid remaining on the mouth and neck portion of the container body as described above is strongly screwed in the screwing direction after the contents are used up, so that the inner lid is strongly upward. Since it is separated from the mouth and neck by receiving force, it can be separated from the mouth and neck of the container body and can be discarded separately from the container body.
However, a container provided with such a lid requires a strong twisting force to separate the inner lid from the mouth and neck of the container body, so it is not easy for children and elderly people with weak fingertips. The appearance of a sealed container having an inner lid that can be easily separated even by a hand with weak fingertip force is desired.
[0012]

Since it adheres closely to the inner surface of 11, the opening of the inner lid 4 can be resealed.
[0034]
If the remaining amount of the contents in the container body 2 runs out during use and the container is to be discarded, as shown in FIG. After the portion 21 is completely separated from the cylindrical wall 9 of the inner lid 4 and the pull ring 17 of the inner lid 4 is exposed to the outside, as shown in FIG. When the knob 27 provided on the portion 23 is picked and pulled in the direction of the arrow, the outer lid cylinder portion 23 is broken along the weakening line 26 provided so that it can be easily removed. The restraint force fixed to the mouth and neck 3 is lost.
[0035]
Therefore, when the pull ring 17 outside the cylindrical wall 9 of the inner lid 4 is picked and raised in the direction of the arrow as shown in FIG. Since the cut line 14 portion of 7c is loosened, the engagement protrusion 13 of the outer cylinder portion 7c engaged with the engagement recess 6 of the mouth-and-neck portion 3 is easily pulled out along the undercut surface. The whole can be pulled out and separated from the mouth-and-neck portion 3 of the container body 2 without effort.
[0036]
In this way, the outer lid body 21, the outer lid cylinder 23 and the inner lid 4 of the outer lid 5, which are different materials, are separated from the mouth and neck of the container body 2, and the container body and the lid are separated. Containers that are disposed of in a state of being separated can be easily separated and collected, so there is no need to separate the containers after collecting the containers as in the prior art, and the container regeneration process becomes easier. The cost for regeneration can be reduced.
[0037]
