Description

【０００１】
【産業上の利用分野】
この発明は、清酒、ジュース又は麺つゆ等のような醗酵の停止又は殺菌のため等の容器に充填する際に加熱を要する液体の場合に用いられる、容器とこれに用いる耐熱キャップに関するものである。
【０００２】
【従来の技術】
従来上記のように容器に充填する際に、充填後の醗酵の停止又は殺菌等のために加熱を要する液体の場合に用いられる容器とこれに用いるキャップは、通常、図１６に示されるように構成されている。
同図において１は容器であり２はその口部を示す。３は中栓であり合成樹脂により構成され、中筒６、上壁８を有し、該上壁８に裂取部７が形成されている。９は注筒を示す。そして前記中栓３外側に合成樹脂により構成された外蓋１４が装着されている。同外蓋１４は外筒１２、中栓３の係合部１０に対する係止部１６、蓋体１３から成っている。
なお２４は内筒、２５は裂溝、２６は裂取部材を示す。２７はヒンジ、２８は掛合部を示す。又５は容器１の口部２外周に形成された凹条４に圧接係止する突条を示す。１５は外筒１２の下端部、２９は加熱液体を示す。
このように構成されたこの耐熱キャップは前記のように加熱液体２９を収容した容器１の口部２に打栓により装着され、前記突条５が前記凹条４に圧接係止する。そしてこの場合前記中筒６が前記加熱液体２９の熱により弾性が減少し、圧接が弱まり、密閉度の減少するのを、外筒１２の圧接により自動的に圧接を補充し、密閉の減少を実用上差支えない程度に抑制している。
【０００３】
【発明が解決しようとする課題】
しかし上記従来の容器とこれに用いる耐熱キャップは次に述べるような問題を有している。それはこの耐熱キャップを容器１の口部２に打栓すると、その凹条４に中栓３の突条５が圧接係合している。従って、容器をリサイクルのために回収する際に容易に外すことができないのである。特に中筒６の外側には外蓋１４の外筒１２が圧接しているため、突条５の圧接が一層強められており、耐熱性でない通常のキャップと異り、外し取りが特に困難である。
この発明は上記のような問題を解決するためになされたもので、容器１の口部２の凹条４に係合する突条５を有する、かつ中筒６の外側に外筒１２の圧接する形式の、中栓３と外蓋１４から成る耐熱キャップにおいて、容器のリサイクル回収に際してきわめて容易にキャップを外し取ることのできる、容器とこれに用いる耐熱キャップを提供することである。
【０００４】
【課題を解決するための手段】
前記の目的を達成するこの発明について述べるとそれは、容器１の口部２に装着する合成樹脂製の中栓３と、該中栓３に設けられた、前記口部２の外周の凹条４に圧接係止する突条５を有する中筒６と、該中筒６上部に設けられた裂取部７を有する上壁８と、前記上壁８上で前記裂取部７外側に設けられた注筒９及び係合部１０と、前記中筒６下端に外方に突出して設けられた環状の下受部１１と、前記中栓３上に装着する、前記中栓３より高い硬度を有し、かつ水の沸点より高い軟化点の合成樹脂製で、前記中筒６外側に圧接する外筒１２及び蓋体１３から成る外蓋１４と、前記下受部１１の突出上面に当接されるようにして収容される前記外筒１２の下端部１５と、該外筒（１２）の上部でかつ内部に設けられた、前記係合部（１０）と圧接係止する係止部（１６）と、前記下受部１１の一部に、前記下端部１５との間に残部３０が残存するようにして形成された栓抜きと掛止する下受欠如部１７と、から成ることを特徴とする容器とこれに用いる耐熱キャップである。
又、該耐熱キャップにおいて、外筒１２の一部に、栓抜きと掛止する外筒欠如部１８を設けた容器とこれに用いる耐熱キャップである。なおこの場合前記外筒欠如部１８が形成されていて、下受欠如部１７は形成されてなくても差し支えはない。又前記の各耐熱キャップにおいて、前記注筒６は前記注筒６の一部に栓抜きを掛止する中筒欠如部１９を有している前記容器とこれに用いる耐熱キャップである。
【０００５】
【発明の実施の形態】
この発明の実施の形態について述べると次の通りである。
容器１の口部２に装着する合成樹脂製の中栓３と、該中栓３に設けられた、前記口部２の外周の凹条４に圧接係止する突条５を有する中筒６と、該中筒６上部に設けられた裂取部７を有する上壁８と、前記上壁８上で前記裂取部７外側に設けられた注筒９及び係合部１０と、前記中筒６下端に外方に突出して設けられた環状の下受部１１と、前記中栓３上に装着する、前記中栓３より高い硬度を有し、かつ水の沸点より高い軟化点の合成樹脂製で、前記中筒６外側に圧接する外筒１２及び蓋体１３から成る外蓋１４と、前記下受部１１上に収容される前記外筒１２の下端部１５と、該外筒１２上部に設けられた前記係合部９と圧接係止する係止部１６と、前記下受部１１の一部に形成された栓抜きと掛止する欠如部１７と、から成ることを特徴とする容器とこれに用いる耐熱キャップである。
【０００６】
この発明は前記のように構成されたことにより、容器１に加熱液体を収容して耐熱キャップを装着すると、前記加熱液体の熱は前記口部２を伝ってまず前記中筒６にもたらされ、このため前記中筒６は加熱されて変形し、口部２に対する圧接の圧力が減少し、密閉力が低下しそうになる。
この場合前記中筒６の外側に圧接させられていた、水の沸点より高い軟化点の外筒１２の圧力が、前記中筒６の圧接の圧力の減少を補充することができるから、前記中筒６と前記口部２間の密閉力の減少は実用上差支えない程度に抑制することができる。そして容器１のリサイクルの場合には前記下受欠如部１７と、この耐熱キャップの上部との間に栓抜きを掛け、この栓抜きの下部を上方に押し上げて前記口部２から外し取る。この場合栓抜きの下部の係止部は直接に又は至近で間接に、前記中栓３より硬度の高い合成樹脂製の外筒１２を押し上げることになり、このため前記押し上げに対し、押し上げられる部分が変形してしまって押し上げにくいもどかしさがなく、直ちに反力が生じ、力が分散することなく直達するから壮快に抜き取ることができる。
【０００７】
又前記下受欠如部１７は下受部１１に形成され、下受部１１は中筒６より大径に形成されているため、栓抜きはその分前記口部の中心から離れた部分にかけることができ、その分大きいモーメントを得ることができ、小さい力で抜きとることができる。
次に他の実施の形態として、前記耐熱キャップにおいて、外筒１２の一部に栓抜きと掛止する外筒欠如部１８を設けた。なおこの場合前記下受欠如部１７は形成されていても、されていなくてもよい。形成されてない場合は後記の他の方法で抜栓する。
まず下受欠如部１７が形成されている場合について述べると、容器１リサイクルの際まず外筒欠如部１８と、この耐熱キャップの上端に栓抜きを掛け、これを上方に回動させて外し取る。
その次に前記下受欠如部１７に栓抜きを掛けて外し取る。即ちこのように二度に分けて外し取ることにより、家庭における婦女子等のように非力な者にもきわめて容易に外し取ることができる。しかもこの場合前記外筒欠如部１８は中栓３より硬度が高いから栓抜きの力によって部分的に変形せず、直ちに反力が生じるからなかなか抜けないもどかしさがなく、直ちに壮快に外し取ることができる。又前記外筒１２は下受部１１上にあるため外筒欠如部１８も前記口部２の中心から離れた部分にあり、このため抜栓の際のモーメントが大きくなるため、小さい力で容易に外し取ることができる。又中栓３は中栓３のみを前記同様な理由により大きなモーメントで、小さい力で、及び中栓３だけなので口部２に対する圧接の力が小さくなっているため容易に外しとることができる。
なお下受欠如部１７の形成されてないものは後記のように他の外し方により外される。
【０００８】
次に更に他の実施形態として、請求項２の形態の耐熱キャップにおいて、中栓３の中筒６に、その一部に栓抜きを掛止する中筒欠如部１９が形成された。この場合中筒欠如部１９は外筒欠如部１２と同形同大に形成され、容器１リサイクルの際、栓抜きは外筒欠如部１８及び前記中筒欠如部１９の両方に一度に掛止し、その両方に力をかけることができる。そして、前記外筒１２は中筒６に圧接して居り、かつ外筒１２は中筒６より硬度が高く、中筒６より半径方向外方のため大きなモーメントで、かつ硬度が高いため反力が直ちに発生するからなかなか抜けないもどかしさがなく、きわめて容易に外し取ることができる。
【０００９】
次に、更に他の実施の形態としては、前記下受欠如部７、外筒欠如部１８、中筒欠如部１９は、それぞれそれらの全体に亘る薄膜部２０を形成してもよい。そしてこの薄膜部２０はそれを設ける部分の厚み方向のどこに設けてもよい。このように形成することにより、それらの欠如部に、空中の浮遊塵埃の侵入を防止できると共に、それらの各欠如部に栓抜きをかけて、上方に回動する際に、それらの欠如部の栓抜きの掛かる部分のみが部分的に上方に変形させられてしまうことに抵抗し、その部分の変形を防止するように応力が作用するから、その分反力の生じるのが早く、上記変形によりなかなか外せないというもどかしさがなく、直ちに壮快に外しとることができる。
【００１０】
次に更に他の実施の形態としては、前記薄膜部２０には該薄膜部２０を裂切り易くする弱化ライン２１が形成されていてもよい。そしてこの弱化ライン２１は薄膜部２０の縁部に沿って形成される。このためこの耐熱キャップを外す場合、上記弱化ライン２１により、栓抜きを掛ける部分を直ちに理解することができる。又その部分は栓抜きの掛止する部分を単に押しつけるだけできわめて容易に破断して栓抜きをその欠如部にかけることができる。
次に、更に他の実施の形態として、前記下受欠如部７、外筒欠如部１８、中筒欠如部１９はそれぞれ盲穴であってもよい。このように形成されたものは、それらの各欠如部の内部に浮遊塵埃の侵入するのを防止でき、又栓抜きによる外し取りの際に、その栓抜きをかけた部分のみが変形してしまってなかなか抜けないもどかしさを与えることがない。その理由は前記盲穴の各部分が一体的に作用し、上記栓抜きをかけた部分のみが変形してしまうのを防止するように応力が生じるからである。
このため、栓抜きをかけて上方に回動すると直ちに壮快に抜取ることができる。次に更に他の実施の形態としては、前記注筒９はその周方向の一部又は全部のつけ根部分の厚さが０．９ｍｍ以下に形成されている。現在一般に市販されている同種キャップの注筒９はそのつけ根部の厚さは１．１ｍｍ程度に形成されている。
【００１１】
なお一実施例としては０．８ｍｍに形成された。このように０．９ｍｍ以下に形成することにより、図１５に示すように栓抜きの上部によって注筒９の一部を押し倒すことにより栓抜きを掛けることが容易にでき、外し取ることができる。なお前記従来のもののように、つけ根部の厚さが１．１ｍｍのものは栓抜き等によっては曲げにくいのである。
次に更に他の実施形態として、注筒９は、その上下方向に複数の破断し易い弱化線２２が形成された。このように構成することにより、前記同様栓抜きにより前記複数の弱化線２２の間を押圧することにより、その部分を押し倒し、或いは破断して栓抜きを掛けることができ、外し取ることができる。
次に更に他の実施の形態として前記中筒６には、上下方向に、かつ下部が下受部１１に及ぶ破断し易い複数の弱化部２３が形成された。
この弱化部２３は一例として溝状に形成され、突条５に相当する部分は、その部分も破断し易いように溝が深く形成されている。
【００１２】
前記のように構成さたことにより、外蓋１４を外し取った後、前記中栓３の中筒６を前記弱化部２３により指等により裂切ることにより、該中筒６の前記口部２に対する圧接力を弱めることができるから、その状態で容易に前記口部２から外し取ることができる。
しかも前記のように弱化部２３は下受部１１に達して形成されているので、外方に突出した下受部１１を摘んで力を加えることにより、前記弱化部２３を容易に裂切ることができる。
【００１３】
【実施例】
図１において、１は容器であり、その口部２に合成樹脂、一例としてポリエチレン製の中栓３が装着されている。４は凹条であり、これに中栓２の中筒６の突条５が圧接している。８は上壁であり、内筒２４の内側の上壁８には裂溝２５により裂取部７が形成されている。
２６はプルリング状の裂取部材を示す。９は注筒、１０は後記外蓋１４と係合する係合部である。又１１は注筒６下端に、外方に突出させた下受部である。
次に１４は外蓋であり、前記中栓３を構成する合成樹脂よりも高い硬度を有し、かつ水の沸点より高い軟化点を有する合成樹脂、一例としてポリプロピレンにより形成されている。
そして前記外蓋１４は、前記中筒６の外側に圧接する外筒１２、蓋体１３から成っており、外筒１２の下端部１５は前記下受部１１上に収容されている。又前記外筒１２上部でかつ内部には前記係合部１０と圧接係止する係止部１６が設けられ、係止されている。そして前記下受部１１の一部には栓抜きと掛止する下受欠如部１７が形成されている。なお２７はヒンジ、２８は蓋体１３の一部に形成された蓋係合部、２９は外筒１２上部一部に構成された蓋係止部を示す。
そして前記下受欠如部１７は一例として図２、図３に示すように下方を開放して形成されたが、又一例として図４、（イ）（ロ）（ハ）（ニ）に示すようにも形成された、図４（イ）に示すものは、図３に示すものと異りヒンジ２７と対応しない側に形成されたものであり、図４（ロ）に示すものは下受部１１の一部をその上下方向とも開放して形成したもの、図４（ハ）に示すものは下受部１１の上方のみを開放して形成したもの、図４（ニ）は下受部１１の上下に残部３０を残して形成したものである。
次に他の実施例として図７（イ）（ロ）に示すように前記外筒１２の一部には栓抜きと掛止する外筒欠如部１８が形成された。なおこの場合同図（イ）（ロ）に示すものは共に下受欠如部１７が形成されているが、これは形成されてなくても差支えはない。
【００１４】
又他の実施例として図１０（イ）、（ロ）に示すように、前記中筒６の一部に栓抜きと掛止する中筒欠如部１９が形成された。この中筒欠如部１９は前記外筒欠如部１８と同形同大に形成され、かつこの両者が対応する同一周方向の位置に形成された。これにより栓抜きは両欠如部１９、１８を一度に掛止して抜き取ることができる。なおこれは夫々別の位置に形成して、別々に抜き取るようにしても差し支えない。次に他の実施例として図５（ロ）、図８（ハ）に示すように前記下受欠如部１７、外筒欠如部１８、及び図１０（イ）、（ロ）に示す中筒欠如部１９は夫々薄膜部２０が形成された。
この薄膜部２０は各欠如部１７、１８、１９の夫々の厚さ方向の任意の位置に形成してもよく、栓抜きの掛止部により容易に破断し得る厚さに形成されている。次に他の実施例として図６、図９に示すように前記薄膜部２０に破断を一層容易にする弱化ライン２１が形成された。この弱化ライン２１はミシン目、連続した穴等により形成され、これにより各欠如部１７、１８、１９の位置を容易に知ることができる。なお弱化ライン２１は各欠如部１７、１８、１９の縁部に沿って形成されている。
【００１５】
次に他の実施例として図５の（イ）、（ロ）に示すように下受欠如部１７は盲穴に形成された。そして図示は省略するが、前記外筒欠如部１８、中筒欠如部１９は盲穴に形成された。但し外筒欠如部１８と中筒欠如部１９の両者が周方向位置で貫通するように形成されているものにあっては、外筒欠如部１８は盲穴に形成されない。
これらの盲穴はその内側に塵埃の侵入を防止し、且つ栓抜きの掛止部の挿入深さを一定にすることができる。
【００１６】
次に他の実施例として図１１に示すように前記注筒９は、その一部又は全部のつけ根部の厚さが０．９ｍｍ以下に形成された。そして一例として０．８ｍｍに形成された。通常、従来の同種キャップの注筒のつけ根部の厚さは１．１ｍｍ程度である。このように薄く構成することにより、図１５に示すように栓抜きの上部で前記注筒９の薄く形成された部分を押圧し、屈曲させることにより栓抜きをかけることができる。
又他の実施例として図１２に示すように、前記注筒９に、上下方向に複数の弱化線２２が形成された。このように構成することにより図１５に示すと同様に栓抜きの上部で前記複数の弱化線２２の間を押圧すると、前記弱化線２２間は図１５と同様に内側に曲げられ、これにより栓抜きを掛けることができる。或いは又弱化線２２間は破断されて倒れ、それにより栓抜きを掛けることができる。
又他の実施例として図１３に示すように、前記中筒６に、上下方向に、かつ下部が下受部１１に及ぶ破断し易い複数の弱化部２３が形成された。このように構成されたことにより、この弱化部２３を破断することにより容易に容器１から外し取ることができる。しかも容器１に装着する場合は、中筒６の外側に中栓３より硬度の高い外筒１２が圧接しているため、この弱化部２３が破断するのを防止できる。
【００１７】
この実施例の耐熱キャップは前記のように構成されたことにより容器１に加熱液体を収容しても、それにより密閉性が大きく損なわれるのを防止することができる。しかも容器１回収の際は図１４に示すように前記下受欠如部１７、或いは外筒欠如部１８、或いは中筒欠如部１９等に栓抜きを掛けて、前記耐熱キャップを取り外すことができる。
【００１８】
【発明の効果】
この発明は、前記のように構成されたことにより、容器１に加熱液体を収容して耐熱キャップを装着すると、前記加熱液体の熱は前記口部２を伝ってまず前記中筒６にもたらされ、このため前記中筒６は加熱されて変形し、口部２に対する圧接の圧力が減少し、密閉力が低下しそうになる。この場合前記中筒６の外側に圧接させられていた水の沸点より高い軟化点の外筒１２の圧力が、前記中筒６の圧力の減少を補充することができるから、前記中筒６と前記口部２間の密閉力の減少は実用上差支えない程度に抑制することができる。そして容器１のリサイクルの場合には前記下受欠如部１７と、この耐熱キャップの上部との間に栓抜きを掛け、この栓抜きの下部を上方に押し上げて前記口部２から外し取る。この場合線抜きの下部の係止部は直接に又は至近で間接に、前記中栓３より硬度の高い合成樹脂製の外筒１２を押し上げることになり、このため前記押し上げに対し、押し上げられる部分が変形してしまって押し上げにくいもどかしさがなく、直ちに反力が生じ、力が分散することなく直達するから壮快に抜き取ることができる。又前記下受欠如部１７は下受部１１に形成され、下受部１１は中筒６より大径に形成されているため、栓抜きはその分前記口部の中心から離れた部分にかけることができ、その分大きいモーメントを得ることができ、小さい力で抜きとることができる。
【００１９】
この発明は前記のように構成されたことにより、容器１のリサイクルの際まず外筒欠如部１８と、この耐熱キャップの上端に栓抜きを掛け、これを上方に回動させて外し取る。その次に前記下受欠如部１７に栓抜きを掛けて外し取る。即ちこのように二度に分けて外し取ることにより、家庭における婦女子等のように非力な者にもきわめて容易に外し取ることができる。しかもこの場合前記外筒欠如部１８は中栓３より硬度が高いから、栓抜きの力によって部分的に変形せず直ちに反力が生じるから、なかなか抜けないもどかしさがなく、直ちに壮快に外し取ることができる。又前記外筒１２は下受部１１上にあるため、外筒欠如部１８も前記口部２の中心から離れた部分にあり、このため抜栓の際のモーメントが大きくなるから、小さい力で容易に外し取ることができる。又中栓３は、中栓３のみを前記同様な理由により大きなモーメントで、小さい力で、及び中栓３だけなので口部２に対する圧接の力が小さくなっているため容易に外しとることができる。なお下受欠如部１７の形成されてないものは後記のように他の外し方により外される。
【００２０】
この発明は前記のように構成されたことにより、容器１のリサイクルの際栓抜きは外筒欠如部１８及び前記中筒欠如部１９の両方に一度に掛止し、その両方に力をかけることができる。そして、前記外筒１２は中筒６に圧接して居り、かつ外筒１２は中筒６より硬度が高く、中筒６より半径方向外方のため大きなモーメントを得ることができるため、反力が直ちに発生するからなかなか抜けないもどかしさがなく、きわめて容易に外しとることができる。
この発明は、前記のように構成され前記外筒１２が前記下受部１１上にあって、外筒欠如部１９、下受欠如部１７とも中筒６より半径方向外方となるため、それぞれ栓抜きにより抜き取る際に、大きなモ−メントを得ることができ、かつ二度に分けて力を加えることができるため、きわめて容易に外し取ることができる。
【００２１】
この発明は、前記のように構成されたことにより、各欠如部１７、１８、１９に空中の浮遊塵埃の侵入を防止できると共に、薄膜部２０が各欠如部１７、１８、１９の外面と同一面に形成されているものにあっては、外見上通常の耐熱キャップと変らない部分を、栓抜きの掛止部で破断することにより栓抜きを掛止できる各欠如部１７、１８、１９に変化させることができる。又薄膜部２０が各欠如部１７、１８、１９の内面と同一面に形成されているものは、それらの各欠如部に栓抜きをかけて、上方に回動する際に、それらの欠如部の栓抜きの掛かる部分のみが上方に変形させられてしまうことに抵抗し、その部分の部分的変形を防止するように応力が作用するから、その分反力の生じるのが早く、上記変形によりなかなか外せないもどかしさがなく、壮快に外し取ることができる。
この発明は前記のように構成されることにより、この耐熱キャップを外す場合、上記弱化ライン２１により、栓抜きを掛ける部分を直ちに理解することができる。又その部分は栓抜きの掛止する部分を単に押しつけるだけできわめて容易に破断して栓抜きをその欠如部にかけることができる。
【００２２】
この発明は前記のように構成されたことにより、欠如部の内部に浮遊塵埃の侵入するのを防止でき、又栓抜きによる外し取りの際に、その栓抜きをかけた部分のみが部分的に変形してしまってなかなか抜けないもどかしさを与えることがない。その理由は前記盲穴の各部分が一体的に作用し、上記栓抜きをかけた部分のみが変形してしまうのを防止するように応力が生じるからである。このため、栓抜きをかけて上方に回動すると直ちに壮快に抜取ることができる。
【００２３】
この発明は、前記のように構成されたことにより、図１５に示すように栓抜きの上部により中筒９の一部を押し倒すことにより、栓抜きを掛けることが容易にでき、外し取ることができる。
この発明は、前記のように構成されたことにより、栓抜きで複数の弱化線２２の間を押圧することにより、その部分を押し倒し、又は破断し、それによって栓抜きを掛けることができ、外し取ることができる。
この発明は前記のように構成されたことにより、外蓋１４を外し取った後、前記中線３の中筒６を、前記弱化部２３により指等により裂切ることにより、該中筒６の前記口部２に対する圧接力を弱めることができるから、その状態で容易に前記口部２から外し取ることができる。しかも前記のように弱化部２３は下受部１１に達して形成されているので、外方に突出した下受部１１を摘みとして利用することができ、下受部１１を摘んで力を加えることにより、前記弱化部２３を容易に裂切ることできる。

[Industrial application fields]
TECHNICAL FIELD The present invention relates to a container and a heat-resistant cap used therefor, which are used in the case of a liquid that requires heating when filling a container for stopping or sterilizing fermentation such as sake, juice or noodle soup. .
[0002]
[Prior art]
Conventionally, when filling a container as described above, a container used in the case of a liquid that needs to be heated to stop fermentation or sterilization after filling, and a cap used therefor are usually as shown in FIG. It is configured.
In the same figure, 1 is a container and 2 shows the mouth part. Reference numeral 3 denotes an inner plug, which is made of a synthetic resin and has an inner cylinder 6 and an upper wall 8, and a tearing portion 7 is formed on the upper wall 8. Reference numeral 9 denotes a barrel. An outer lid 14 made of synthetic resin is attached to the outside of the inner plug 3. The outer lid 14 includes an outer cylinder 12, a locking portion 16 for the engaging portion 10 of the inner plug 3, and a lid body 13.
Reference numeral 24 denotes an inner cylinder, 25 denotes a fissure, and 26 denotes a tearing member. Reference numeral 27 denotes a hinge, and 28 denotes a hooking portion. Reference numeral 5 denotes a protrusion that presses and locks to a recess 4 formed on the outer periphery of the mouth portion 2 of the container 1. Reference numeral 15 denotes a lower end portion of the outer cylinder 12, and 29 denotes a heating liquid.
The heat-resistant cap configured as described above is attached to the mouth portion 2 of the container 1 containing the heating liquid 29 by the stopper as described above, and the protrusion 5 is press-fitted and locked to the recess 4. In this case, the elasticity of the inner cylinder 6 is reduced by the heat of the heating liquid 29, the pressure contact is weakened, and the sealing degree is decreased. The pressure reduction of the outer cylinder 12 is automatically replenished to reduce the sealing. Suppressed to such an extent that it does not interfere with practical use.
[0003]
[Problems to be solved by the invention]
However, the conventional container and the heat-resistant cap used therefor have the following problems. That is, when the heat-resistant cap is plugged into the mouth 2 of the container 1, the protrusion 5 of the inner plug 3 is in pressure contact with the recess 4. Therefore, it cannot be easily removed when the container is collected for recycling. In particular, since the outer cylinder 12 of the outer lid 14 is in pressure contact with the outer side of the intermediate cylinder 6, the pressure contact of the protrusion 5 is further strengthened, and unlike a normal cap that is not heat resistant, it is particularly difficult to remove. is there.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described as follows.
A synthetic resin inner plug 3 to be attached to the mouth portion 2 of the container 1, and an inner cylinder 6 having a protrusion 5 provided on the inner plug 3 and press-fitting to a concave stripe 4 on the outer periphery of the mouth portion 2. An upper wall 8 having a tearing portion 7 provided on the upper portion of the middle cylinder 6, a casting cylinder 9 and an engaging portion 10 provided on the outer side of the tearing portion 7 on the upper wall 8, and the middle cylinder 6 A ring-shaped receiving portion 11 provided projecting outward at the lower end and a synthetic resin having a higher hardness than the inner plug 3 and a softening point higher than the boiling point of water, which is mounted on the inner plug 3. Thus, an outer cover 14 composed of an outer cylinder 12 and a lid 13 that are in pressure contact with the outer side of the middle cylinder 6, a lower end portion 15 of the outer cylinder 12 accommodated on the lower receiving portion 11, and an upper portion of the outer cylinder 12 It comprises a locking portion 16 that presses and locks the engaging portion 9 provided, and a bottle opener formed on a part of the lower receiving portion 11 and a lacking portion 17 that latches. A container and heat cap used therefor to.
[0006]
Since the present invention is configured as described above, when the heating liquid is accommodated in the container 1 and a heat-resistant cap is attached, the heat of the heating liquid is first brought to the middle cylinder 6 through the mouth portion 2. For this reason, the inner cylinder 6 is heated and deformed, the pressure of the pressure contact with the mouth portion 2 is reduced, and the sealing force is likely to be reduced.
In this case, since the pressure of the outer cylinder 12 having a softening point higher than the boiling point of water, which has been pressed against the outer side of the middle cylinder 6, can supplement the decrease in pressure of the middle cylinder 6. The decrease in the sealing force between the tube 6 and the mouth portion 2 can be suppressed to such an extent that there is no practical problem. When the container 1 is recycled, a bottle opener is hung between the under-missing portion 17 and the upper portion of the heat-resistant cap, and the lower portion of the bottle opener is pushed upward to be removed from the mouth portion 2. In this case, the locking portion at the lower part of the bottle opener pushes up the outer cylinder 12 made of synthetic resin having a hardness higher than that of the inner plug 3 directly or in the immediate vicinity, so that the portion pushed up against the push-up. Since it is deformed, there is no frustration that is difficult to push up, a reaction force is generated immediately, and the force reaches directly without being dispersed, so it can be pulled out magnificently.
[0007]
Further, the lower receiving portion 17 is formed in the lower receiving portion 11, and the lower receiving portion 11 is formed to have a diameter larger than that of the middle cylinder 6, so that the bottle opener is applied to a portion far from the center of the mouth portion. Therefore, a large moment can be obtained and extracted with a small force.
Next, as another embodiment, in the heat resistant cap, an outer cylinder lacking portion 18 that hooks with a bottle opener is provided on a part of the outer cylinder 12. In this case, the under-receiving portion 17 may or may not be formed. If it is not formed, it is unplugged by another method described later.
First, the case where the base lacking portion 17 is formed will be described. First, when the container 1 is recycled, the outer tube lacking portion 18 and the upper end of the heat-resistant cap are hung, and the upper end is turned upward to be removed. .
Next, the undercut portion 17 is unscrewed and removed. That is, by removing in two steps in this way, it can be very easily removed even by a weak person such as a woman or a girl in the home. Moreover, in this case, the outer cylinder lacking portion 18 is harder than the inner plug 3, so that it is not partially deformed by the force of opening the bottle, and since there is a reaction force immediately, there is no frustration that cannot be easily removed, and it should be removed immediately and magnificently. Can do. Further, since the outer cylinder 12 is on the lower receiving portion 11, the outer cylinder lacking portion 18 is also located away from the center of the mouth portion 2, and therefore the moment at the time of unplugging is increased, so that it can be easily performed with a small force. Can be removed. Further, the inner plug 3 can be easily removed because only the inner plug 3 has a large moment and a small force for the same reason as described above, and since only the inner plug 3 has a small pressure contact force against the mouth portion 2.
In addition, the thing in which the under lacking part 17 is not formed is removed by other removal methods as will be described later.
[0008]
Next, as still another embodiment, in the heat-resistant cap according to the second aspect of the present invention, a middle tube lacking portion 19 is formed on the middle tube 6 of the middle plug 3 so as to hook a bottle opener. In this case, the middle cylinder lacking part 19 is formed in the same shape and size as the outer cylinder lacking part 12, and when the container 1 is recycled, the bottle opener is hooked on both the outer cylinder lacking part 18 and the middle cylinder lacking part 19 at a time. And you can apply power to both. The outer cylinder 12 is in pressure contact with the middle cylinder 6, and the outer cylinder 12 has a higher hardness than the middle cylinder 6, and is a larger moment because it is radially outward than the middle cylinder 6, and a reaction force due to its higher hardness. Since it occurs immediately, there is no irritating trouble that can be easily removed.
[0009]
Next, as still another embodiment, the under lacking portion 7, the outer tube lacking portion 18, and the middle tube lacking portion 19 may each form a thin film portion 20 over the entirety thereof. And this thin film part 20 may be provided anywhere in the thickness direction of the part which provides it. By forming in this way, intrusion of airborne dust in the air can be prevented in those lacking portions, and when each of these lacking portions is bottlenecked and rotated upward, Resisting that only the portion where the bottle opener is deformed is partially deformed upward, and stress acts so as to prevent the deformation of that portion. There is no frustration that it is difficult to remove, and you can remove it immediately and magnificently.
[0010]
Next, as still another embodiment, a weakening line 21 that facilitates tearing of the thin film portion 20 may be formed in the thin film portion 20. The weakening line 21 is formed along the edge of the thin film portion 20. For this reason, when removing this heat-resistant cap, the weakening line 21 can immediately understand the portion to be uncapped. Further, the portion can be broken very easily by simply pressing the portion where the bottle opener is engaged, and the bottle opener can be applied to the lacking portion.
Next, as yet another embodiment, the under-receiving lack part 7, the outer cylinder lacking part 18, and the middle cylinder lacking part 19 may each be a blind hole. Those formed in this way can prevent floating dust from entering the inside of each of the lacking parts, and only the part where the bottle opener has been deformed when being removed by the bottle opener. It doesn't give the frustration that is hard to miss. The reason is that each part of the blind hole acts integrally, and stress is generated so as to prevent deformation of only the part where the bottle opener is applied.
For this reason, when the bottle is opened and it is turned upward, it can be immediately and smoothly removed. Next, as still another embodiment, the note tube 9 is formed such that the thickness of a part or all of the base portion in the circumferential direction is 0.9 mm or less. Currently, the same-type cap casting tube 9 that is generally available on the market has a base portion with a thickness of about 1.1 mm.
[0011]
In one example, the thickness was 0.8 mm. Thus, by forming 0.9 mm or less, as shown in FIG. 15, the bottle opener can be easily put on and removed by pushing down a part of the barrel 9 by the upper part of the bottle opener. In addition, like the above-mentioned conventional one, the thickness of the base portion of 1.1 mm is difficult to bend depending on the bottle opener.
Next, as yet another embodiment, the tube 9 has a plurality of weakening lines 22 that are easily broken in the vertical direction. By comprising in this way, by pressing between the some weakening lines 22 by a bottle opener like the above, the part can be pushed down or it can break | disconnect and can be opened, and it can remove.
Next, as yet another embodiment, a plurality of weakened portions 23 that are easy to break are formed in the middle tube 6 in the vertical direction and the lower portion extends to the receiving portion 11.
The weakened portion 23 is formed in a groove shape as an example, and a portion corresponding to the protrusion 5 is formed deeply so that the portion is easily broken.
[0012]
With the configuration described above, after the outer lid 14 is removed, the inner cylinder 6 of the inner plug 3 is torn by a finger or the like through the weakening portion 23, whereby the mouth portion 2 of the inner cylinder 6 is cut. Therefore, it is possible to easily remove it from the mouth 2 in this state.
Moreover, since the weakened portion 23 is formed so as to reach the lower receiving portion 11 as described above, the weakened portion 23 can be easily torn by applying force by picking the lower receiving portion 11 protruding outward. Can do.

【The invention's effect】
This According to the present invention, when the heating liquid is accommodated in the container 1 and the heat-resistant cap is attached, the heat of the heating liquid is first brought to the middle cylinder 6 through the mouth portion 2. For this reason, the inner cylinder 6 is heated and deformed, the pressure of the pressure contact with the mouth portion 2 is reduced, and the sealing force is likely to be reduced. In this case, since the pressure of the outer cylinder 12 having a softening point higher than the boiling point of the water pressed against the outside of the intermediate cylinder 6 can supplement the decrease in the pressure of the intermediate cylinder 6, The decrease in the sealing force between the mouth portions 2 can be suppressed to such an extent that it can be practically used. When the container 1 is recycled, a bottle opener is hung between the under-missing portion 17 and the upper portion of the heat-resistant cap, and the lower portion of the bottle opener is pushed upward to be removed from the mouth portion 2. In this case, the latching portion at the lower part of the line punching directly or indirectly pushes up the outer tube 12 made of a synthetic resin having a hardness higher than that of the inner plug 3, so that the portion pushed up against the pushing up Since it is deformed, there is no frustration that is difficult to push up, a reaction force is generated immediately, and the force reaches directly without being dispersed, so it can be pulled out magnificently. Further, the lower receiving portion 17 is formed in the lower receiving portion 11, and the lower receiving portion 11 is formed to have a diameter larger than that of the middle cylinder 6, so that the bottle opener is applied to a portion far from the center of the mouth portion. Therefore, a large moment can be obtained and extracted with a small force.
[0019]
This According to the above configuration, when the container 1 is recycled, first, the outer cylinder lacking portion 18 and the upper end of the heat-resistant cap are put on a bottle opener, which is rotated upward to be removed. Next, the undercut portion 17 is unscrewed and removed. That is, by removing in two steps in this way, it can be very easily removed even by a weak person such as a woman or a girl in the home. Moreover, in this case, since the outer cylinder lacking portion 18 is harder than the inner plug 3, it is not partially deformed by the force of opening the bottle, and a reaction force is immediately generated. be able to. Further, since the outer cylinder 12 is on the receiving portion 11, the outer cylinder lacking portion 18 is also located at a portion away from the center of the mouth portion 2, and therefore, the moment at the time of unplugging is increased, so that it is easy with a small force. Can be removed. Further, the inner plug 3 can be easily removed because only the inner plug 3 has a large moment and a small force for the same reason as described above, and since only the inner plug 3 has a small pressure contact force against the mouth portion 2. . In addition, the thing in which the under lacking part 17 is not formed is removed by other removal methods as will be described later.
[0020]
This According to the present invention, as described above, when the container 1 is recycled, the bottle opener is hooked on both the outer cylinder lacking portion 18 and the middle cylinder lacking portion 19 at a time, and force is applied to both. Can do. Since the outer cylinder 12 is pressed against the middle cylinder 6 and the outer cylinder 12 is harder than the middle cylinder 6 and is radially outward from the middle cylinder 6, a large moment can be obtained. Since it occurs immediately, there is no irritating irreparableness and it can be removed very easily.
This According to the present invention, since the outer cylinder 12 is configured on the lower receiving portion 11 and both the outer cylinder lacking portion 19 and the lower receiving lacking portion 17 are radially outward from the middle cylinder 6. When pulling out with a bottle opener, a large moment can be obtained, and since force can be applied in two portions, it can be removed very easily.
[0021]
This According to the present invention, since it is configured as described above, it is possible to prevent airborne dust from entering the respective lacking portions 17, 18, 19, and the thin film portion 20 is the same as the outer surface of each lacking portion 17, 18, 19. For those formed on the surface, the portions that do not change from the normal heat-resistant caps are broken at the stoppers of the bottle opener so that the bottle openers can be hooked to the respective lacking parts 17, 18, 19 Can be changed. The thin film portion 20 is formed on the same surface as the inner surface of each of the lacking portions 17, 18 and 19, when the respective lacking portions are stoppered and rotated upward. Resisting that only the portion of the bottle opener is deformed upward, and stress acts so as to prevent partial deformation of that portion, the reaction force is quickly generated by that amount. There is no frustration that can hardly be removed, and it can be removed magnificently.
This According to the present invention configured as described above, when the heat-resistant cap is removed, the weakening line 21 can immediately understand the portion to be uncapped. Further, the portion can be broken very easily by simply pressing the portion where the bottle opener is engaged, and the bottle opener can be applied to the lacking portion.
[0022]
This According to the present invention, as described above, floating dust can be prevented from entering the inside of the lacking portion, and only the portion where the bottle opener is applied when removing it by the bottle opener. It doesn't give the frustration that it's deformed and doesn't come off easily. The reason is that each part of the blind hole acts integrally, and stress is generated so as to prevent deformation of only the part where the bottle opener is applied. For this reason, when the bottle is opened and it is turned upward, it can be immediately and smoothly removed.
[0023]
This Since the present invention is configured as described above, the bottle opener can be easily put on and removed by pushing down a part of the middle cylinder 9 with the upper part of the bottle opener as shown in FIG. it can.
This According to the present invention, by being pressed between the plurality of weakening lines 22 with a bottle opener, the portion can be pushed down or broken, thereby enabling the bottle opener to be removed. Can be taken.
This Since the present invention is configured as described above, after the outer lid 14 is removed, the middle cylinder 6 of the middle line 3 is torn by the weakened portion 23 with a finger or the like. Since the pressure contact force with respect to the mouth portion 2 can be weakened, it can be easily detached from the mouth portion 2 in that state. In addition, since the weakened portion 23 is formed to reach the lower receiving portion 11 as described above, the lower receiving portion 11 protruding outward can be used as a knob, and the lower receiving portion 11 is picked to apply force. As a result, the weakened portion 23 can be easily split.
