Description

【０００１】
【産業上の利用分野】
本発明は、開口部が大きな容器の口頸部にヒンジ又は蝶番を介して蓋体を開閉可能に連結した蓋付きの密閉容器に関するもので、特に、容器の開口端部または蓋の内面に設けた密閉用のパッキン体に蓋または開口端の係合片を強固に密着させることができる密閉容器に係わるものである。
【０００２】
【従来の技術】
開閉可能な蓋付きの密閉容器としては、実開昭６０−１１５８５３号や実開昭６０−１３６９４９号公報に記載するように、ねじキャップを用いて密封するものが一般的であり、これ等の考案に見るように、円筒状をした容器の口頸部に形成した螺条溝に、蓋体の内面に環状または円板状のパッキン材を張設したねじ蓋を螺合せしめて密閉する容器が多用さている。
しかし、上記した考案のような構造をした容器では、蓋体を開閉する度に、指先に力を入れてねじ蓋を強く捻じる操作を繰り返さなければならず非常に面倒であり、また、蓋を外した時に蓋の置き場所に困ったり、蓋を不用意に落としたりする恐れもある。
【０００４】
そこで、上記したようなねじ蓋付きの容器に変わるものとして、容器本体に蝶番やヒンジを介して蓋体を開閉自在に組付けた容器が、蓋の開閉操作が容易であり、且つ、安全である等の理由から多用されるようになった。
しかし、このような形式の容器では、蝶番等による結合部分を気密状に保つことが非常に困難であるので、実開昭６３−２０２６５１号公報に記載されるように、開口部の口径を小さくして、蓋の下面に容器の開口部内に密着して嵌入する栓片を垂設した構造にした、開口部が小さい液体注出容器に限定利用されており、クリームを収容する容器のように大きい開口部を必要とする容器には利用できなかった。
【０００５】
従って、このような形式の蓋体を大きな開口部を有する容器に適用するには、上記の蓋面に垂設した栓片に代わるものとして、蝶番を介して連結した蓋体とは別に容器本体の開口部を単独で密閉する中栓蓋を設けておいて、該中栓蓋により容器の大きな開口を密閉してから、蝶番蓋体で閉蓋するようにしたものがあるが、このような容器の蓋体を開閉するに際しては、中栓蓋を開けるという余分な操作をしなければならず不便であった。
【０００６】
そこで、このような不便さを解消するために、実公平２−２９３９３号公報に記載する考案のように、有底の円筒容器の大きな開口部を密閉する中蓋に外蓋を結合した二重蓋を蝶番により開閉可能に連結した密閉容器がある。
上記の容器は、容器本体の口頸部に横方向に設けたピンに内蓋の一端に形成したスリットを嵌合枢着して、該内蓋に筒状の嵌合周壁を有する外蓋を回動可能に嵌合した二重蓋を容器口頸部に開閉可能に構成し、前記内蓋は内面に環状弾性材をパッキンとして設けて容器本体の口頸部に対して開閉自在となすと共に、外蓋を回動することによって蓋体を閉止または開放するようにして、蓋体を容器本体から分離することなく開閉可能としたものであるが、蓋体を二重としたので構造が複雑になり、生産コストが高くつくことになる欠点がある。
【０００７】
上記したような問題点をなくした蓋付きの密閉容器として、図８に示すような構造をしたものを、実公平２−４９１８号として本発明の出願人は先に提案している。
即ち、大きな開口部を有する筒形状をした容器本体２の口頸部２ａに、筒状の周壁３ａとその上端部が内向きの鍔状に形成した頂壁３ｂとを有する組付き体３を、前記口頸部上端面と頂壁との間にパッキン体４のリング板４ａを挟着して螺合すると共に、前記組付き体３の上面後端部に蓋体５を開閉可能に蝶番により連結して、前記開口部を直接密閉できるようにして密封容器１を構成して、前記頂壁３ｂの下面に位置するパッキン体４をそのリング板４ａ内周縁から蓋板５ａ下面に密に接するように筒形状をした口筒片４ｂを立設して、該口筒片の上端縁全周を閉状態にある蓋板下面に密接するように形成して密封容器を構成する。
【０００８】
そして、前記パッキン体４は、口頸部の上端面に上方から対向するリング板部の周端縁部分を肉厚となしてシール部４ｃとなして、容器本体２への蓋体の組付き体３を螺合することにより、シール部４ｃが口頸端部２ｂと頂壁部３ｂとの間で強く押し潰されて、パッキン体４は容器口部に密着される。
また、前記パッキン体４は、その口筒片４ｂの外周面には起立状態に維持するための係止周条が周設され、且つ、上端の全周縁部分には上方に縮径した肉薄の先端筒片４ｄが周設されて蓋板５ａ下面に密着している。
しかし、上記した密封容器は、容器の実質的な開口部がパッキン体により形成されるので、蓋体の蝶番連結部分を容器の密閉機能部分から完全に分離することができて、容器の開口部の大きさを自由に設定することができるので、蓋体の蝶番連結部分に係わりなく容器の密閉を行うことはできるが、パッキン体の口筒片を起立状態の形状を維持するために、ある程度の硬さを持った材質によりパッキン体を形成しなければならず、開口端部と蓋板面との密着性を犠牲にしなければならないという欠点があった。
【０００９】
そこで、本発明の出願人は上記の点を改良すべく、容器の密閉度を更に向上させるために、実質的に容器の開口部を形成しているパッキン体を、柔軟性に富んだ材質、即ち柔軟な弾性材、特にエラストマーを用いて構成して、容器の開口端部と蓋体内面との密封性を高めたものとして、図９に示すような構造の密閉容器を提案している。
即ち、容器本体２の円筒状の口頸部２ａに円筒部３ａと内鍔状の頂壁部３ｂとからなる組付け体３を螺合して、環状板部４ａとその内周縁に口筒片４ｂを立設した弾性エラストマーからなるパッキン体４を挟着し、前記組付け体３の上面後端部に設けた凹部に蓋板５ａの後端部に突設した蝶番片を連結軸６を介して開閉可能に連結して蓋付き密封容器１を構成し、該蓋板５ａの内面に前記口筒片４の上端周縁に設けた接触片４ｄと密着する環状の係合隔壁５ｄを設けてなる蓋体５を、容器本体の開口部に密着させて密閉するようにして密封容器を構成する。
そして、上記パッキン体の組付け体に接する部分の環状板部分から口筒片部にわたる面に、パッキン体の形状を保持するための断面Ｌ字状のパッキン支持体が接合して設けることにより、容器の開口部を形成する前記口筒片部の上端周縁に設けた接触片と蓋体内面に設けた係合隔壁との密着性をより良く保持するようにしたものである。
【００１０】
【発明が解決しようとする課題】
上記のように組付け体と共に開口部を形成するパッキン体の口筒片に接触片を設けて構成した密封容器は、通常の状態に於いては密閉性は良好ではあるが、蓋体に思わない横向きの強い力が作用すると、係合隔壁が一条であるので蓋面が僅かではあるが容器本体に対する蓋板の結合部分で横方向にずれて、接触片と係合隔壁との間の密閉性が損なわれる恐れがあり、特に、容器本体に蓋体をヒンジ結合したものは蝶番結合したものに比べて横ずれを生じ易い欠点がある。
そこで、蓋体が閉じられている時に、横向きの力を受けても蓋体が横方向にずれるのを防止するための構成を設けることにより、蓋体と開口端部との間の密着性を強固なものとすることが望まれる。
【００１１】
【課題が解決するための手段】
上記したような種々の問題点を解決すべく本発明は、容器本体の口頸部に螺合されて、蝶番やヒンジを介して蓋体を開閉可能に連結した組付き体と口頸部上端面との間に挟着されるパッキン体を、従来のポリエチレン製等よりも柔軟な弾性材料、特に、エラストマーを用いた弾性材料により構成して、容器の開口部と蓋体との密封性を改善し、更には、柔軟なパッキン体を所定形状に維持させるために、前記パッキン体の環状板部と口筒片部との表面部にパッキン押さえを設けて補強する。
また、蓋体の内面にパッキン体の口筒片先端部または組付き体の開口周壁先端部と係合する環状の係合凹溝を設けて二条の隔壁となして、蓋体に横方向の力を受けた場合には該係合凹溝内に組付き体の開口周壁先端部を係合保持して蓋体の横ずれを防ぐようにして、容器本体の開口端部と蓋体の内面との密着状態を強固に保持せしめて、容器の密閉度を向上させるようにする。
【００１２】
【発明の実施の形態】
容器本体の円筒状口頸部の上端面と蓋体を開閉可能に連結してなる組付け体の頂壁との間に環状のパッキンを挟着して、前記組付け体を容器本体の口頸部に螺合して密封容器を構成して、前記組付け体の頂壁の内周縁に立設した開口周壁の先端部を、蓋体内面に形成した環状係合溝に設けた弾性材料からなるパッキン体に密着係合するようにして密封容器が構成されるか、もしくは、弾性材料、中でもエラストマーで形成したパッキン体の環状板部を容器本体の開口部上端面と組付き体の頂壁との間に挟着した状態で、蓋体を蝶番により開閉可能に連結した組付き体を螺合せしめると、前記パッキン体の環状板部は組付き体の頂壁により容器本体の開口端部に強く押圧、圧縮されて、容器本体に蓋体が強固な密着状態に結合されて密封容器が構成される。
前記蓋体の内面には、パッキン体の口筒片先端部または組付き体の開口周壁先端部を係合する環状係合溝を設けているので、容器の蓋体が閉じられると、パッキン体の環状板部の内周縁から立設した口筒片の上端部が、容器の開口部を形成する組付き体の開口周壁から突出した状態に形成されており、該口筒片の上端部周縁に設けた接触片は柔軟なエラストマーできているので、蓋板の内面に密着した状態で蓋体の環状係合溝内に押圧されて弾性変形して、蓋体の係合溝と容器本体の開口端部とは、蓋体が蝶番で連結された位置には関係なしに全周面で均一に密着させることができる。
【００１３】
【実施例】
以下、本発明を好適な実施例にもとづいて、添付した図面を参照しつつ説明する。
本願発明の第一実施例である蓋付きの密封容器１は、図１乃至３に示すように、有底の筒形状をした容器本体２と、該容器本体の口頸部２ａに環状の弾性パッキン８を介して螺合した組付け体３と、該組付け体の上面後端部に開閉可能に蝶番片５ｂにより連結した蓋板５ａとから構成される。
前記容器本体２は、大きな開口部を備えた有底の円筒形状をなしており、該容器本体２の口頸部２ａの外周には、蓋体５を接合するための組付け体３を螺合するねじ部が形成されている。
【００１４】
同じく蓋体５の組付け体３は、容器本体２の口頸部２ａに組付ける円筒部３ａとパッキン８を容器本体２の口頸部２ａに押圧固定する内鍔状の頂壁３ｂとを有し、該頂壁３ｂの内周縁には開口周壁３ｃが立設して設けられ、また、該組付け体の頂壁３ｂの上面後端部には、蓋板５ａを蝶番により連結するための凹部が形成されて、該凹部に蓋板５ａの後端部に突設した蝶番片５ｂを連結軸６により開閉可能に連結すると共に、前記頂壁３ｂの上面前端部には、蓋板５ａを開放するための斜面３ｄが設けられ、前記組付け体の円筒部３ａの内面には螺合ねじが設けられて構成される。
そして、蓋体５の内面には、組付き体３の開口周壁先端部３ｆを係合密着する環状係合溝５ｊが２条の突壁５ｇ，５ｈにより凹状に形成されており、該係合凹溝内にはエラストマーを用いて断面が凹状に形成された環状のパッキン体４が嵌合固定して設けられている。
【００１５】
上記のような構成をしてなる本発明の蓋付き密封容器１は、以下のような構造をしたものに形成される。
即ち、有底の円筒形状をした開口部の大きな容器本体２の口頸部２ａの上端面に環状のパッキン８を接して設け、該環状パッキン板の上から組付け体３の鍔状の頂壁３ｂ面で押圧して、組付け体３の円筒部３ａの螺合ねじを容器本体２の口頸部２ａの外周面に設けたねじ部に螺合して固定することにより、組付け体の上面後端部に開閉可能に蝶番片５ｂにより蓋板５ａを連結した蓋体５が容器本体２の口頸上端部２ｂに密接に組付けられて密閉容器１に構成される。
【００１６】
このような構成をした容器１内にクリーム等の化粧料やその他の粘稠材を充填した後、前記蓋体５の組付け体３を口頸部２ａに螺合してから、開口部に対して蓋体５を押圧して閉じると、組付き体３の開口周壁３ｃの先端係合片３ｆが蓋板（天板）５ａの内面に形成した環状の係合溝５ｊ内のパッキン体４に密着係合すると共に、蓋板５ａの先端部内面に設けた係止片５ｃが組付き体の開口周壁３ｃの係合突起３ｅに係合して蓋体５を密閉係止して、容器本体２の口頸部の上端部２ｂと蓋体５の内面とが強固に密着状態に保持される。
そして、上記のようにして閉蓋された容器の蓋体５を開くには、蓋板５ａの先端部に揺動可能に連結した押圧片７を指先で内側へ押圧することにより、押圧片７の下端部７ａが組付け体３の頂壁３ｂの上面に形成された斜面３ｄ上を滑動して、係止片５ｃに上向きの力が働くので、係止突起３ｅとの係合状態が解除されて、蓋体５は開口部の上方へ開放される。
【００１７】
また、本願発明の第二実施例である蓋付きの密封容器１は、図４乃至６に示すように、有底の筒形状をした容器本体２と、該容器本体の口頸部２ａにパッキン体４を挟んで螺合した組付け体３と、該組付け体の上面後端部に開閉可能にヒンジ６ａにより連結した蓋板５ａとから構成される。
前記容器本体２は、大きな開口部を備えた有底の円筒形状をなしており、該容器本体２の口頸部２ａの外周には、蓋体５を接合するための組付け体３を螺合するねじ部が形成されている。
【００１８】
同じく、組付け体３には、容器本体２の口頸部２ａに組付ける円筒部３ａとパッキン体４を容器本体２の口頸部の上端部２ｂに押圧固定する内鍔状の頂壁３ｂとを有し、該頂壁３ｂには、その上面外寄りに係合片３ｇを、その内周縁に立設する開口周壁３ｃの先端に係合突起３ｈがそれぞれ設けられ、そして、該組付け体３の頂壁３ｂの上面後端部には、一体形成されてなるヒンジ６ａ部により蓋板５ａの後端部が開閉可能に連結されている。
また、前記蓋板５ａの前端部には、蓋体５を開放するための指掛け片５ｋが設けられると共に、蓋体５の内面には、前記組付き体３の開口周壁３ｃの先端部の係合突起３ｈが係合する環状係合溝５ｊが２条の突壁５ｇ，５ｈにより形成されて蓋体５を構成している。
【００１９】
パッキン体４は、弾性変形が容易なエラストマーを用いて形成されており、容器本体２の口頸部の上端部２ｂに接する環状板部４ａの外周端縁部に肉厚のシール部４ｃを設けると共に、環状板部４ａの内周縁には口筒片４ｂを起立して設けて、該口筒片４ｂの上端縁部には肉薄な接触片４ｄを突壁５ｈに圧縮係合可能に形成されている。
そして、前記柔軟なパッキン体４の形状を維持するための保持手段として、該パッキン体４が組付け体３に接する部分の環状板部４ａから口筒片部４ｂにかけての面には断面Ｌ字状のパッキン支持片４ｅを接合して補強されている。
【００２０】
上記のような構成からなる本発明の蓋付き密封容器１は、以下のような構造に形成したものになる。
即ち、有底の円筒形状をした容器本体２の大きな開口をした口頸上端部２ｂの上面に上記パッキン体４の環状板部４ａを接した状態に設けておいて、該環状板部の上から上記組付け体３の鍔状の頂壁３ｂの下面で押圧して、円筒部３ａの螺合ねじを容器本体２の口頸部２ａの外周面に設けたねじ部に螺合して固定すると、肉厚のシール部４ｃが押し潰され
【００２１】
このようにして容器本体２の口頸部２ａに組付けられたパッキン体４の口筒片４ｂの上端縁部に設けられた接触片４ｄおよび組付け体３の開口周壁３ｂの先端縁部に設けられた係合突起３ｈは、蓋体５が開かれた状態にある時には開口部から突出して起立状態にあり、容器の開口部を蓋体で密閉しようとする時には、開放状態の位置にある蓋板５ａの上面に指先または掌を当てて開口部に押圧すると、組付け体３の頂壁３ｂの上面の外寄りに環状に設けられた係合片３ｇは蓋体の内周壁面に密着係合すると共に、組付け体３の頂壁３ｂの開口周壁３ｃ先端部の係合突起３ｈおよびパッキン体４の口筒片４ｂの上端縁の接触片４ｄは蓋体の内面に形成した環状の係合溝５ｊ内にそれぞれ係合して、蓋体５は容器本体２の開口部を密閉した状態に保持される。
【００２２】
そして、このように蓋体５が閉じられた状態になると、前記パッキン体４はエラストマーにより形成されているので、口筒片４ｂの上端縁の接触片４ｄは、開口周壁３ｃ先端の係合突起３ｈと一体になって蓋板５ａの内面の環状係合溝５ｊ内に密着するように圧縮係合されるので、容器の開口部を形成したパッキン体は全接触周面で蓋体面を強固に密閉することができる。
更に、開口周壁３ｃに設けられた係合片３ｇおよび係合突起３ｈは、蓋体５の内周面と環状係合溝５ｊの突壁５ｇ面にそれぞれ強固に密接係合されているので、蓋体に横向きの衝撃力等が働いても、係合片３ｇ、係合突起３ｈ及び係合凹溝５ｊの突壁５ｇ，５ｈにより受け止められるので、蓋体が横ずれして密閉状態が損なわれる恐れもない。
【００２３】
また、上記のように閉蓋された容器の蓋体５を開くには、蓋板５ａの先端部に設けられた指掛け片５ｋを指先で上方へ押圧することにより、蓋体内面の係合部と接触片４ｄおよび係合突起３ｈと係合片３ｇとの係合状態が解除できて、蓋体５は開口部の上方へ開放される。
【００２４】
上記の説明から明らかなように、本発明は、パッキン体４を柔軟なエラストマーにより形成して、該パッキン体の形状を維持するために、パッキン体を開口部に固定した組付け体３に接する部分に断面Ｌ字状のパッキン支持片４ｅを設けて補強したり、また、蓋体５の内面にパッキン体の口筒片４ｂの接触片４ｄおよび組付き体の開口周壁の係合突起３ｈを係合する環状の係合凹溝５ｊが形成されたり、または、該凹溝内に弾性パッキン体を設けて、接触片が蓋体５の環状係合溝５ｊ内の全周面で接触するようにしたので、蓋体は容器の開口部に緊密に密閉したものとなる。
【００２５】
本発明は、上記した図５及び６に示したような、パッキン体４の環状板部４ａ及び口筒片部４ｂが組付け体３に接する部分に断面Ｌ字状のパッキン押さえ４ｅを接合した構造のパッキン体を用いたものに限られず、図７に示すように、前記パッキン押さえ４ｅを組付け体３に接する部分とは反対側に接合した構造のものを用いても、同様な効果を得ることができる。
また、上記の実施例に於いては、組付け体３への蓋体５の連結に蝶番を用いたものについて説明したが、蓋体５を組付け体３に直接ヒンジ結合したものであっても、蝶番を用いたものと同様の密封性を得ることができることは言うまでもない。
【００２６】
【発明の効果】
以上説明したように、本発明は、容器の開口部を実質的に形成するパッキン体を、柔軟なエラストマーにより形成したので、蓋体を連結する蝶番部分は容器開口部を密閉する機能部分から分離することができて、開口部の大きな容器の密封も完全に行うことが可能である。
また、開口周壁に設けられた係合片および係合突起は、蓋体の内周面と環状係合溝の壁面に強固に密接していてるので、蓋体に横向きの衝撃力が働いたとしても、蓋体が横ずれして密閉状態が損なわれる恐れもない。
従って、本発明のような構造のパッキン体と組付け体及び蓋体を備えた容器にすれば、いろんな大きさの開口面積を有する容器の開口部を密封できると共に、蝶番やヒンジ連結された蓋体は開閉操作が容易であるので、内容物の取り出しを円滑に行うことができる。

[Industrial application fields]
The present invention relates to a sealed container with a lid in which a lid is connected to a mouth and neck of a container having a large opening via a hinge or a hinge, and in particular, provided on the opening end of the container or the inner surface of the lid. Further, the present invention relates to a sealed container capable of firmly attaching a lid or an engagement piece at an open end to a sealing packing body.
[0002]
[Prior art]
As a closed container with a lid that can be opened and closed, a container sealed with a screw cap is generally used as described in Japanese Utility Model Laid-Open Nos. 60-115853 and 60-136949. As can be seen from the idea, there is a container that is sealed by screwing a screw lid in which an annular or disk-shaped packing material is stretched on the inner surface of a lid body into a thread groove formed in the mouth and neck of a cylindrical container. It is heavily used.
However, in the container having the structure as described above, every time the lid is opened and closed, the operation of applying a force to the fingertip and twisting the screw lid strongly must be repeated, which is very troublesome. When removing the cover, there is a risk that the lid may be in trouble, or that the lid may be dropped carelessly.
[0004]
Therefore, as an alternative to a container with a screw lid as described above, a container in which the lid body is assembled to the container body via a hinge or hinge so that the lid can be opened and closed easily and safely. It came to be used frequently for some reason.
However, in this type of container, it is very difficult to keep the joint portion by a hinge or the like in an airtight state. Therefore, as described in Japanese Utility Model Laid-Open No. 63-202651, the aperture diameter is reduced. In addition, it is limited to a liquid dispensing container with a small opening, which has a structure in which a stopper piece that fits closely into the opening of the container is installed on the lower surface of the lid, like a container that contains cream It was not available for containers that require large openings.
[0005]
Therefore, in order to apply a lid of this type to a container having a large opening, the container main body separate from the lid connected via a hinge as an alternative to the plug piece suspended from the lid surface. There is an inner cap lid that seals the opening of the container alone, and a large opening of the container is sealed with the inner plug lid and then closed with a hinge lid. When opening and closing the lid of the container, an extra operation of opening the inner stopper lid must be performed, which is inconvenient.
[0006]
Therefore, in order to eliminate such inconvenience, a double lid in which an outer lid is combined with an inner lid that seals a large opening of a bottomed cylindrical container as in the idea described in Japanese Utility Model Publication No. 2-29393. There is an airtight container that can be opened and closed by a hinge.
The container has a slit formed at one end of the inner lid fitted to a pin provided in the lateral direction on the mouth and neck of the container body, and an outer lid having a cylindrical fitting peripheral wall is attached to the inner lid. A double lid that is pivotably fitted is configured to be openable and closable on the container neck and neck, and the inner lid is provided with an annular elastic material as a packing on the inner surface so that it can be opened and closed with respect to the container neck and neck. By rotating the lid, the lid is closed or opened so that the lid can be opened and closed without being separated from the container body. However, the structure is complicated because the lid is doubled. There is a drawback that the production cost is high.
[0007]
The applicant of the present invention has previously proposed an airtight container with a lid that eliminates the problems as described above and having a structure as shown in FIG.
That is, the assembled body 3 having a cylindrical peripheral wall 3a and a top wall 3b whose upper end portion is formed in an inward hook shape on the mouth and neck portion 2a of the cylindrical container body 2 having a large opening. The ring plate 4a of the packing body 4 is sandwiched and screwed between the upper end surface of the mouth and neck and the top wall, and the lid 5 can be opened and closed at the rear end of the upper surface of the assembly 3 To form the sealed container 1 so that the opening can be directly sealed, and the packing body 4 positioned on the lower surface of the top wall 3b is tightly connected from the inner peripheral edge of the ring plate 4a to the lower surface of the lid plate 5a. A tube-shaped piece 4b having a cylindrical shape so as to come into contact is formed, and the entire circumference of the upper end edge of the piece is formed so as to be in close contact with the lower surface of the lid plate in the closed state, thereby forming a sealed container.
[0008]
And the said packing body 4 thickens the peripheral edge part of the ring board part which opposes the upper end surface of a mouth neck part from upper direction, and becomes the seal part 4c, and the assembly of the cover body to the container main body 2 is carried out By screwing the body 3, the seal portion 4 c is strongly crushed between the mouth neck portion 2 b and the top wall portion 3 b, and the packing body 4 is in close contact with the container mouth portion.
In addition, the packing body 4 is provided with a locking peripheral line for maintaining the standing state on the outer peripheral surface of the mouthpiece piece 4b, and the entire peripheral edge part at the upper end has a thin diameter reduced upward. A distal end cylindrical piece 4d is provided around and is in close contact with the lower surface of the lid plate 5a.
However, since the substantial opening of the container is formed by the packing body, the hinge connecting part of the lid can be completely separated from the sealing function part of the container, and the container opening The size of the container can be set freely, so that the container can be sealed regardless of the hinge connection part of the lid, but in order to maintain the shape of the packing barrel piece upright, There is a drawback that the packing body must be formed of a material having a hardness of 5 mm, and the adhesion between the opening end and the lid plate surface must be sacrificed.
[0009]
Therefore, in order to improve the above-mentioned point, the applicant of the present invention further improves the hermeticity of the container by using a packing material that substantially forms the opening of the container, a highly flexible material, That is, an airtight container having a structure as shown in FIG. 9 is proposed as a structure made of a flexible elastic material, particularly an elastomer, to improve the sealing performance between the open end of the container and the inner surface of the lid.
That is, the assembly 3 comprising the cylindrical portion 3a and the inner wall-shaped top wall portion 3b is screwed into the cylindrical mouth-neck portion 2a of the container body 2, and the annular plate portion 4a and the inner peripheral edge thereof are connected to the mouthpiece. A packing body 4 made of an elastic elastomer with an upright piece 4b is sandwiched, and a hinge piece protruding from the rear end portion of the cover plate 5a is connected to a concave portion provided at the rear end portion of the upper surface of the assembly 3 to the connecting shaft 6 A lidded sealed container 1 is configured so as to be openable and closable via an opening, and an annular engagement partition wall 5d is provided on the inner surface of the lid plate 5a so as to be in close contact with the contact piece 4d provided on the peripheral edge of the mouthpiece piece A sealed container is configured such that the lid 5 formed in close contact with the opening of the container body is hermetically sealed.
