Description

【０００１】
【発明の属する技術分野】
本発明は収容した貯液を断熱保温する断熱構造を有した保温貯液容器に関するものである。
【０００２】
【従来の技術】
このような保温貯液容器として、昇温環境と降温環境とを繰り返す移動機器、例えば自動車のエンジンの冷却水の循環系に組み込まれる保温タンクが知られている（例えば、特許文献１参照。）。このものは、金属製の真空二重容器を断熱構造として採用しており、エンジンの動作に伴い循環されながら昇温していく冷却水を断熱容器本体内に隔壁を通じ導入して、エンジン停止後内容器１内に停滞する昇温冷却水を保温する。これに対し、断熱容器以外の循環域の冷却水は自然冷却する。次のエンジンの動作開始時、冷却水の循環も開始されて、断熱容器内で保温していた昇温冷却水がエンジンの冷却に供される。これによってエンジンの起動時の温度の立ち上がりを助けて動作初期から所定の燃焼効率を確保できるようにする。
【０００３】
隔壁は、前記断熱容器内への冷却水の導入とこれに伴う昇温冷却水の導出による入れ替わりが互いの混合なくスムーズに行われるようにするもので、冷却水の導入域に設けられて、導入冷却水を拡散して昇温冷却水の保温域に広域から及ばせることにより、昇温冷却水が導入冷却水の混合なく高い温度のまま導出されるようにする。
【０００４】
ところで、隔壁とこれを収容する内容器は、前記冷却水の導入と導出に微妙な影響を与える。このためそれら隔壁や内容器の位置や形状は導入冷却水とこれに伴う保温中の昇温冷却水との入れ替わりを互いの混合なくスムーズに図るのに重要である。
【０００５】
本発明の実施例を示す図１を参照して説明すると、容器本体である真空二重容器１０を構成する内容器１の肩部１ｂは比較的大きな丸みのある形状が望ましく、隔壁４は図１に１つの例を示すように前記肩部１ｂの内側近傍に適正な姿勢にて設けるのが好適である旨報告されている。
【０００６】
しかし、内容器１の肩部１ｂの丸みのある形状は、隔壁を適正な位置および姿勢に取り付けるのに困難があって、前記特許文献１に記載のものは、図１に示す保温中の昇温冷却水を導出する導出管２２の回りに支持して設けている。この支持が確かなように、導出管２２を真空二重容器１０の容器口１０ａと、内容器１の底部との２箇所で支持している。
【０００７】

【０００８】
【発明が解決しようとする課題】
しかし、内容器１はその成形誤差によって各部の径や真円度、形状に誤差があるので、導出管２２によって支持した隔壁４と内容器１の内面とが全域で均一に接することは困難で、導入冷却水が保温中の昇温冷却水に乱入し混合するようなことを招く不均一な隙間が生じやすい。また、自動車の走行中の振動や急発進、急停止時のショックにて液体の入った内容器１に歪みが生じるようなことがあると、前記不均一な隙間が発生したり増大したりする。
【０００９】
本発明の目的は、例え真空二重容器の内容器の肩部であっても、隔壁を容易かつ適正に取り付け、その状態を保持できる保温貯液容器を提供することにある。
【００１０】
【課題を解決するための手段】
上記の目的を達成するために、本発明の保温貯液容器は、収容した貯液を断熱保温する断熱構造を有した保温貯液容器であって、容器本体の内部に隔壁を設けるのに、この隔壁の外周に折り曲げ形成した複数の取り付け片、連続した取り付け周壁または端部からの切り込みを周方向に複数有した周壁を、前記容器本体の内面に嵌め合わせて溶接付けしたことを主たる特徴としている。
【００１１】
このような構成では、隔壁をその外周部で容器本体の内面に嵌め合せて溶接付けするので、容易かつ確実に一体化して取り付けることができ、以降、相互補強の関係も手伝って容器本体と隔壁との初期取り付け状態を維持しやすい。同時に、隔壁の容器本体の内面への取り付け部が、隔壁の外周に折り曲げ形成した取り付け片、周方向に連続した周壁または端部からの切り込みを周方向に複数有した周壁であって、これらのいずれもが少なくとも有している隔壁の外周部での折り曲げ構造によって厚み方向に幾分のスプリング効果を得て、容器本体の内面との嵌め合いを相互の形状や寸法の誤差を吸収して位置決め通りの位置および姿勢の関係で前記溶接付けによる取り付けを達成することができるし、前記嵌め合いのために隔壁が変形して特性を損なうようなこともない。
【００１２】
隔壁は中央貫通穴のまわりにそれよりも小さな複数の拡散穴を有し、取り付け片間または切り込みは、隔壁と容器本体の内面との間に隙間を形成している、さらなる構成では、
隔壁が容器本体の液体の導入域に位置して、中央貫通穴のまわりの小さな複数の拡散穴にて、導入液を拡散して保温中の液に広域から及ばせ、中央貫通穴を通じて保温中の液が導入液の混合なく高い温度のまま導出されるようにするような場合に、容器本体の内面と隔壁との位置関係が安定していることによって、隔壁の取り付け片間または切り込みによって容器本体の内面と隔壁との間に、設定通りの均一な大きさおよび形状の隙間を形成して、この隙間を前記拡散穴のさらに外まわりでの精度よい拡散通路として利用し、導入液の拡散域の増大により導入液と導出液の入れ替わりをより混合なくスムーズに達成されるようにする。
【００１３】
折り曲げ片間または切り込み幅は、複数の貫通穴の径よりも大きい、さらなる構成では、
隙間の幅を小さく抑える分、折り曲げ片間または切り込み幅に対応する隙間長さを大きくして、導入液が保温中の液内に乱入し混合するような導入を規制しながら必要な拡散流量が得られるようにすることができる。
【００１４】
取り付け片または取り付け周壁は、容器本体の軸線まわりのほぼストレートな筒面部に嵌め合わせて溶接付けしてある、さらなる構成では、
隔壁の嵌め合わせだけで嵌め合わし相手がほぼストレートな嵌め合わせにし縁が生じない筒面であることによって、所定位置に所定の姿勢で安定させられるので、適正な位置および適正な姿勢に溶接付けしやすい。
【００１５】
隔壁が、取り付け片または取り付け周壁からの立ち上がり周壁を内容器から離れて形成した皿型である、さらなる構成では、
容器本体が金属製の真空二重容器で内容器の丸みのある肩部の内側に隔壁を設けるような場合でも、前記立ち上がり周壁がある分だけ取り付け片または取り付け周壁が隔壁から離れて位置するので、内容器の丸みのある肩部を避けた位置を利用して丸みの影響なく嵌め合わせて容易に位置決めし溶接付けすることができる。同時に、立ち上がり周壁は容器本体の内面から離れているので、溶接付け時の容器本体の内面との隔壁の嵌め合いや位置決めを複雑にしたり不便をもたらしたりしない。また、皿型形状は隔壁の変形強度を高め、容器本体の内面との相互補強効果が向上する。
【００１６】
立ち上がり周壁を取り付け片または取り付け周壁との間に段部を持って形成している、さらなる構成では、
段部の変形強度は高く、隔壁全体の強度と隔壁と容器本体との相互補強効果を高める上、取り付け片または取り付け周壁と容器本体内面との嵌め合いによる変形が隔壁はもとよりその外周の立ち上がり周壁に及ぶことをも防止することができ、隔壁が変形することはもとより、立ち上がり周壁に変形や歪みが生じて隔壁が傾いたりするようなことも防止することができる。
【００１７】
本発明のそれ以上の目的および特徴は、以下に続く詳細な説明および図面の記載によって明らかになる。本発明の各特徴はそれ自体単独で、あるいは種々な組合せで複合して採用することができる。
【００１８】
【実施例】
以下、本発明の実施例について幾つかの例とともに図１〜図１１を参照しながら説明し、本発明の理解に供する。
【００１９】
本実施例の図１〜図５に示す例、図６〜図８に示す例、図９〜図１１に示す例のそれぞれは、保温貯液容器の１つの例として真空二重容器１０を容器本体に採用し、１つの用途例として前記した自動車のエンジンの冷却水の循環経路に置かれて、エンジンの動作に伴い循環される冷却水が導入され還流しながら昇温していく。エンジン停止後内容器１内に停滞した昇温冷却水は、内外容器１、２の間を真空空間３としてあることによって保温することになる。これに対し、内容器１以外の循環域では自然冷却する。次のエンジンの動作開始時、冷却水の循環も開始されて、内容器１内で保温していた昇温冷却水が冷却水の導入を伴い導出されて保温温度にてエンジンに供給される。これによってエンジンの動作開始時の温度の立ち上がりを助けて動作初期から所定の燃焼効率を確保できるようにする。内容器１内の肩部１ｂの内側近くには導入冷却水を内容器１の横断面方向に一様に拡散させる拡散穴４ａを有した隔壁４を内容器１内を横切る向きにて設け、導入冷却水の一様な拡散により内容器１内に保温貯留中の昇温冷却水をこれと極力混合しないで、従って温度低下をみないで押し出し還流させられるようにしてある。
【００２０】
もっとも、保温貯液容器は、お茶やコーヒー、紅茶などの嗜好飲料、スポーツ飲料などの各種飲料を収容して、保温または保冷しながら、その時々の利用や使用、例えば電動ポンプ、手動ポンプ、傾倒などによる注ぎ出し、飲み口などからの直飲み、ストローによる吸い飲み、などに供するのに広く利用されており、複数種類の内溶液を個別に収容して、１つの容器口や上下など個別に設けた容器口を通じ個別に飲用や利用に供することが考えられる。また、別に、将来、隔壁を有した保温貯液容器の機能を活かした新たな用途がさらに開発されることも予想される。また、隔壁を設けるのに容器本体を横切る向きに限られることはなく、用途に応じて軸線とどのように交差し、あるいは平行に配置されたり、部分的に設けられたりすることがあってもよい。
【００２１】
本実施例の真空二重容器１０は保温、保冷を行う断熱容器であることと、強度および耐蝕性の関係から、内外容器１、２は熱伝動性の低いステンレス鋼を採用してある。しかし、これに限られることはなく、使用目的や使用状況に応じたものを選択使用すればよい。
【００２２】
また、内容器１は特に、図１〜図５に示す例、図６〜図８に示す例のように、底部が下に凸の緩やかな湾曲形状部１ｄとこの湾曲形状部１ｄから胴部１ｃに丸みをなして繋がる丸み部１ｅを有し、胴部１ｃは口部１ａに向けやや斜めに立ち上がる肩部１ｂに丸みを持った丸み部１ｆを介して繋がっている。口部１ａは肩部１ｂから小さな丸みを持った丸み部１ｇを介してストレートに立ち上がった形状を有し、前記隔壁４による導入冷却水の拡散作用とともに、前記冷却水のスムーズな導入、拡散と、これによる保温中の昇温冷却水の、導入冷却水の混合がないスムーズな流出、還流とを確保できるようにしている。さらに、内容器１の口部１ａの上端部には外側に斜め上向きの段部１ｈを有して拡径した拡径部１ｉを設けて外容器２との接合を図ることにより、外容器２により支持されるときの強度を確保している。
【００２３】
一方、外容器２は、図１〜図５に示す例では、ストレートな胴部２ｃから小さな二重の段部２ｄを介し肩部２ｂに繋がっている。肩部２ｂは段部２ｄから前記口部２ａに向かって内容器１の肩部１ｂよりも大きな角度で斜めに立ち上がるテーパー形状部８０を経て前記平坦部７０となった後、さらに傾斜のきついテーパー形状部８０を有した後、垂直な口部２ａに至り、内容器１の前記拡径部１ｉとの溶接などによる気密接合を図っている。なお、真空空間３内での脱気を図るゲッタ４２は１つの例として平坦部７０の内側に取り付けてあるが、真空空間３内であればどの位置に設けてもよい。このようにした外容器２は、肩部２ｂの２つのテーパー形状部８０がなす傾斜、特に立ち上がり角度の大きな内周側のテーパー形状部８０によって、内容器１の口部１ａのラジアル方向への変位に対し、外周側のテーパー形状部８０および平坦部７０によって内容器１の平坦部底部側への変位に対し、それぞれやや吸振性を持って支持し、反底部側への変位には引っ張り力を働かせて、確固に支持するので、真空二重容器１０が自動車に搭載されて、冷却水を導入している内容器１が外容器２内を介した外部からの振動や急激な慣性力を受けても、それにより振動するようなことを防止しながら変位したり損傷するようなことを防止することができる。
【００２４】
また、図６に示す例の外容器２は、ストレートな胴部２ｃの上端から小さな丸み部２ｅを介して、内容器１の肩部１ｂよりややきつめであるが緩やかな立ち上がりのテーパー形状部８０を持った肩部２ｂをなした後、小さな丸み部２ｆにて口部２ａに至り、内容器１の口部１ａとの接合を図っている。この場合、丸み部２ｆが内容器１のラジアル方向の支持に若干の吸振性を発揮し、テーパー形状部８０によって、内容器１のスラスト方向の支持に若干の求心性を発揮することができる。ストレートな胴部２ｃの上部内面には複数のゲッタ４２が設けられている。このようにした外容器２は、内容器１の口部１ａのラジアル方向の支持において若干の弾性を持って吸振作用を発揮するので、真空二重容器１０が自動車に搭載されて、冷却水を導入している内容器１が外容器２内を介した外部からの振動や急激な慣性力を受けても、それにより振動するようなことを防止しながら変位したり損傷するようなことを防止することができる。
【００２５】
しかし、真空二重容器１０を構成するのに、内外容器１、２をどのような形状に形成し、また、結合してもよいが、本例の真空二重容器１０のようにした内容器１の肩部２ｂの内側近傍に隔壁４を設けるには、前記丸み部１ｆがあるために、従来首尾よく配置されなかった。
【００２６】
これに対応して本実施例では、金属製の真空二重容器１０における内容器１の上記のような丸み部１ｆを持った肩部１ｂの内側近傍に隔壁４を設けるような場合であっても、隔壁４を容易かつ適正に取り付け、かつその取付状態を保持できるようにするため、隔壁４の外周に折り曲げ形成した図１〜図５に示す例のような複数の取り付け片１２１、図示していない連続した取り付け周壁または図６〜図８に示す例、図９、図１０に示す例のような端部からの切り込み１２２ａを周方向に複数有した周壁１２２を、容器本体の内面である真空二重容器１０の内容器１の内面に嵌め合わせて、１つの例としてスポット溶接部１２３にて示したように溶接付けしている。しかし、溶接の方式は特に問わない。
【００２７】
このように、本実施例では隔壁４を、その外周部４ｇで内容器１の内面に嵌め合せて溶接付けするので、容易かつ確実に一体化して取り付けることができ、以降、相互補強の関係も手伝って内容器１と隔壁４との初期取り付け状態を維持しやすい。同時に、隔壁４の内容器１の内面への取り付け部が、隔壁４の外周に折り曲げ形成した取り付け片１２１、周方向に連続した周壁または端部からの切り込み１２２ａを周方向に複数有した周壁１２２であることによって、これらのいずれもが少なくとも有している隔壁４の外周部４ｇでの折り曲げ構造によって厚み方向に幾分のスプリング効果を得て、内容器１の内面との嵌め合いを相互の形状や寸法の誤差を吸収して位置決め通りの位置および姿勢の関係で前記溶接付けによる取り付けを達成することができるし、前記嵌め合いのために隔壁４が変形して特性を損なうようなこともない。
【００２８】
なお、隔壁４の上記のような内容器１との嵌め合わせや溶接付けは、内容器１の図１〜図５の例の図２、図５に示し、図６、図７の例の図６に示すような接合部４４の接合前において、内容器１の胴部１ｃの上半部内に、まだ開口している接合端から、隔壁４をその取り付け片１２１や取り付け周壁１２２部で圧入するなどして嵌め合わせ、内容器１の胴部１ｃの内周に溶接付けすることになり、内外からの挟み付けによるスポット溶接でも容易に行える。もっとも、他の溶接方法を採用することもできるし、溶接に代えてろう接によって固着し、取り付けてもよい。この際、隔壁４の各所に形成する前記取り付け片１２１や取り付け周壁１２２の下端などが形成する各種のエッジ部や、各種の面を、接合部４４の接合端から所定量押し込むことによって隔壁４を内容器１内の所定位置に簡単かつ容易に押し込み固定に供することができる。この場合、隔壁４の押し込み位置および姿勢を内容器１の接合端を基準にして押し込み工具の最終押し込み位置および押し込み姿勢を規制することにより隔壁４を高精度に設けることができる。
【００２９】
ここで、図１〜図５の例、図６〜図８の例、図１１の例での隔壁４は、前記導入液とその導入に伴う導出液の導出とが相互が混合しないスムーズな入れ替わりのために前記外周部４ｇを有した天井部４ｃに中央貫通穴４ｄのまわりにそれよりも小さな複数の拡散穴４ａを有する一方、図１〜図５の例の取り付け片１２１間は図１、図５に示すように、また図６〜図８の例、図１１の例の切り込み１２２ａは、図に示すように、それぞれ隔壁４と内容器１の内面との間に隙間１２４を形成している。これにより、隔壁４が真空二重容器１０の液体の導入域、従って内容器１の液体の導入域に位置して、中央貫通穴４ｄのまわりの小さな複数の拡散穴４ａにて、導入液を拡散して保温中の液に広域から及ばせ、中央貫通穴４ｄ、これを貫通する導出管２２を通じて保温中の液が導入液の混合なく高い温度のまま導出されるようにするのに、内容器１の内面と隔壁４との位置関係が前記のように安定していることによって、隔壁４の取り付け片１２１間または切り込み１２２ａによって内容器１の内面と隔壁４との間に、設定通りの均一な大きさおよび形状の隙間１２４を形成することができ、この隙間１２４を前記拡散穴４ａのさらに外まわりでの精度よい拡散通路として利用し、導入液の拡散域の増大により導入液と導出液の入れ替わりをより混合なくスムーズに達成されるようにする。
【００３０】
また、それぞれにおいて、折り曲げ片１２１の間隔Ｗ、切り込み１２２ａの幅Ｘは、複数の拡散穴４ａの径よりも大きく設定してある。このようにすると、隙間１２４の幅Ｙを小さく抑える分、取り付け片１２１の間隔Ｗや切り込み幅Ｘに対応する隙間長さＬを大きくして、導入液が保温中の液内に乱入し混合するような導入を規制しながら必要な拡散流量が得られるようにすることができる。
【００３１】
しかも、取り付け片１２１、取り付け周壁１２２は、容器本体の軸線まわりのほぼストレートな筒面部、本例では真空二重容器１０の内容器１におけるほぼストレートな筒面部をなす胴部１ｃの内面に嵌め合わせて、前記スポット溶接部１２３で示すように溶接付けしてある。これにより、隔壁４の嵌め合わせだけで、嵌め合わせ相手が嵌め合わせに滑りの生じないほぼストレートな胴部１ｃの内面であることによって、嵌め合わせた隔壁４を所定位置に所定の姿勢で安定させられるので、適正な位置および適正な姿勢に溶接付けしやすい。
【００３２】
隔壁４はさらに、図１〜図７に示す例では図１、図５、図７に示し、図８〜図１０の例では図８に示すように、取り付け片１２１や取り付け周壁１２２からの立ち上がり周壁１２５を内容器１から離れて形成した皿型としてある。このようにすると、容器本体が金属製の真空二重容器１０で内容器１の丸み部１ｆを有した肩部１ｂの内側に隔壁４を設けるような場合でも、前記立ち上がり周壁１２５がある分だけ取り付け片１２１や取り付け周壁１２２が、天井部４ｃが実質的になす隔壁４から離れて位置することになるので、内容器１における肩部１ｂの丸み部１ｆを避けた位置を利用して、従って、上記のように胴部１ｃを利用して丸み部１ｆの影響なく嵌め合わせることで容易に位置決めし溶接付けすることができる。同時に、立ち上がり周壁１２５は内容器１の内面から離れているので、溶接付け時の内容器１の内面との隔壁４の嵌め合いや位置決めに無関係となり、これら嵌め合いや位置決めを複雑にしたり不便をもたらしたりしない。また、皿型形状は隔壁４の変形強度を高め、内容器１の内面との相互補強効果が向上する。
【００３３】
図１〜図５に示す例の隔壁４は、立ち上がり周壁１２５が取り付け片１２１の上部が内容器１から離れるように傾斜していることと、この傾斜に沿って立ち上がり周壁１２５自体が傾斜していることとによって、その全体が内容器１から適度に離れ、導入液が前記隙間１２４に適度に達するようにしている。もっとも、隔壁４の外周部４ｇが内容器１の丸み部１ｆの内面に接触して、外周部４ｇの外まわりには導入液が達しないように規制することもできる。また、隔壁４の天井部４ｃの中央貫通穴４ｄと拡散穴４ａとの形成域の間に上に凸となるほぼ台形断面をした環状のビード６３を形成して耐振動性や、内容器１内への押し込み時の押圧部となるときの変形剛性を高めている。
【００３４】
図６〜図８の例の隔壁４は図６、図７に示すように、立上がり周壁１２５が取り付け周壁１２２との間に段部１２６を持つことによって内容器１から離れた位置でほぼ垂直に立ち上がって天井部４ｃに繋がり、天井部４ｃが中央貫通穴４ｄの近傍まで緩い上向きの傾斜を持って延びている。この天井部４ｃの傾斜部と中央貫通穴４ｄとの間に環状壁６５を設けて、段部１２６による高い変形強度とで耐振動性を確保する形態としてある。環状壁６５はその内向きのフランジ部６５ａを天井部４ｃに溶接するなどして取り付けてある。切り込み１２２ａ前記段部１２６にまで少し及んで形成している分だけ、取付け周壁１２２の板厚よりも大きな幅の隙間１２４を形成している。しかし、隙間１２４の幅の大きさは自由に設定できる。
【００３５】
前記段部１２６は隔壁４全体の強度向上に加え、隔壁４とこれを嵌め合わせた内容器１との相互補強効果を高める上、取り付け片または取り付け周壁と容器本体内面との嵌め合いによる変形が隔壁４の天井部４ｃはもとよりその外周の立ち上がり周壁１２５に及ぶことをも防止することができ、隔壁４が変形することはもとより、立ち上がり周壁１２５に変形や歪みが生じて隔壁４が傾いたりするようなことも防止することができる。
【００３６】
図９〜図１１に示す例は、図６〜図８に示す例の場合と取り付け周壁１２２の切り込み１２２ａがその途中までしか形成されず、隔壁４と内容器１の内面との間に導入液を通す隙間を形成していない点で相違し、中央貫通穴４ｄまわりの内側一列に形成した拡散穴４ａの数を図６〜図８に示す例の場合よりも倍加させて、拡散穴４ａが不足しないようにしてある。
【００３７】
また、別に、取り付け周壁１２２は、その全体または切り込み１２２ａの形成範囲程度に、内容器１の胴部１ｃに対して図９に示すような圧入代ｔを持つように下方外側に若干斜めとなるように形成してある。これにより、胴部１ｃとの間で図９に示すような若干の隙間ｕを有した状態でスポット溶接部１２３で示すように溶接付けして取り付けるようにしてある。取り付け周壁１２２は前記のような傾斜を有した部分の下端からの切り込み１２２ａにより周方向複数箇所で分断するのに、切り込み１２２ａの幅Ｘよりも切り込み１２２ａ間の寸法Ｘ１を大きくすることで、前記斜め形状による内容器１の胴部１ｃへの圧入力、取り付け周壁１２２の胴部１ｃ内面への食い込み力を高めてスポット溶接時の位置ずれを防止できるようにしている。もっとも、前記隙間ｕは圧入を容易にはするが特に必要なものではない。これは図８〜図１０に示す例の場合にも適用して有効である。
【００３８】
以下、本実施例の各例における他の特徴について、さらに説明する。前記平坦部７０の平坦性を利用して図１〜図５の例のように各種の付帯物６０を溶接などして容易に取り付けられる利点がある。また、付帯物６０として、上に凸となった環状のチャンネル部材２１を、その下向き開口に有するフランジ２１ａを平坦部７０に当てがい溶接などによって固着し、肩部２ｂの面剛性を高める補強と、外装部材や導出パイプ２２や導出口２３と外部配管との接続部材（いずれも図示せすず）を取り付け穴２４を利用してネジ止めし取り付ける取り付け台になるようにしている。取り付け穴２４は特に、チャンネル部材２１の環状な凸部の周方向複数箇所に形成した取り付け凸部２１ｂに形成して、他の付帯物をこの取り付け凸部２１ｂを利用して接触面積、接触域少なく取り付けられるようにしている。これによって他の付帯物との取り付けのための面合わせが楽に行える。
【００３９】
平坦部７０に設けた前記環状凸部を有している形態では、それが別体のチャンネル部材などによるものでなくても、外容器２の平坦部７０自体で形成したものであっても、肩部２ｂの特に平坦部７０の面剛性を高めるのに役立つ。
【００４０】
前記平坦部７０はいずれの場合も、肩部２ｂの胴部２ｃ上端部から口部２ａへ立ち上がる部分に形成している。これにより、前記テーパー形状部８０等の斜め、あるいは垂直などの各種立上がり形態に平坦部７０を複合することで、肩部２ｂの保形性を高めながら平坦部７０を得て、チャンネル部材２１や取り付け金具３１などの付帯物６０を取り付けやすくすることができる。平坦部７０は、また、肩部２ｂの口部２ａ寄りに形成してある。これにより、平坦部７０にて口部２ａまわりの付帯物６０を取り付けたりするのに好適なものとなる。
【００４１】
図１〜図５に示す例、および図６〜図８に示す例では、特に、内容器１の口部１ａ以外を外容器２に保温性よく支持して変位や損傷を防止できる耐振動性の高いものとするため、金属製の真空二重容器１０は、内外容器１、２の底部間にピン状や環状などの支持部材１１を溶接付けなどして備え、内容器１の底部を外容器２の底部によって前記支持部材１１を介して支持するようにしてある。
【００４２】
図１〜図５の例、図６〜図８の例の外容器２は共通して、図２、図３〜図５、図６に示すようにストレートな胴部２ｃの下端に内向きの少しの段部２ｋを介して下方に延びるストレートな筒部２ｌの途中に外向きに突出するように板金加工したビード２ｍを形成して変形剛性を高め、このビード２ｍを有した筒部２ｌに底部材２ｏの外周に形成した下向きの筒壁２ｐを嵌め合わせてＴＩＧ溶接などにより気密接合している。底部材２ｏは筒部２ｌの上端に上向きの稜部２ｑをなして後中央側下方に斜めに延びる第１の傾斜部２ｒを有するとともに、この第１の傾斜部２ｒに少しの水平部２ｓを介して同じく中央側下方に斜めに延びる第２の傾斜部２ｔを有し、この第２の傾斜部２ｔから中央側に水平に延びる第１の水平部２ｕ、この水平部２ｕから少しの段部２ｘを介して内側に延びる中央水平部２ｖを有し、この中央水平部２ｖにて内容器１の底部から下方に延びる橋渡し部材１１を支持するようにしている。また、前記稜部２ｑには図２、図６、図８に示すような周方向に多数配列された半径方向に軸線が向く断面Ｖ型の窪み２ｗを形成している。
【００４３】
このようにした底部材２ｏは、平面剛性が高く、内容器１の底部を支持部材１１を介し内容器２の底部によって確固に軸線方向、径方向に支持することができる。
【００４４】
【発明の効果】
本発明の保温貯液容器の主たる特徴によれば、隔壁をその外周部で容器本体の内面に嵌め合せて溶接付けするので、容易かつ確実に一体化して取り付けることができ、以降、相互補強の関係も手伝って容器本体と隔壁との初期取り付け状態を維持しやすい。同時に、隔壁の容器本体の内面への取り付け部が、隔壁の外周に折り曲げ形成した取り付け片、周方向に連続した周壁または端部からの切り込みを周方向に複数有した周壁であって、これらのいずれもが少なくとも有している隔壁の外周部での折り曲げ構造によって厚み方向に幾分のスプリング効果を得て、容器本体の内面との嵌め合いを相互の形状や寸法の誤差を吸収して位置決め通りの位置および姿勢の関係で前記溶接付けによる取り付けを達成することができるし、前記嵌め合いのために隔壁が変形して特性を損なうようなこともない。
【００４５】

BACKGROUND OF THE INVENTION
The present invention relates to a heat retaining liquid storage container having a heat insulating structure for heat insulating and storing stored liquid.
[0002]
[Prior art]
As such a heat retaining liquid container, there is known a moving device that repeats a temperature rising environment and a temperature decreasing environment, for example, a heat retaining tank incorporated in a cooling water circulation system of an automobile engine (see, for example, Patent Document 1). . This product uses a metal vacuum double container as a heat insulation structure. Cooling water, which is circulated as the engine operates, is introduced into the main body of the heat insulation container through a partition wall, and after the engine stops. The temperature rising cooling water stagnating in the inner container 1 is kept warm. On the other hand, the cooling water in the circulation area other than the heat insulating container is naturally cooled. At the start of the next engine operation, the circulation of the cooling water is also started, and the heated and cooled water kept in the heat insulating container is used for cooling the engine. This helps to ensure a predetermined combustion efficiency from the beginning of operation by helping the temperature rise when the engine is started.
[0003]
The partition wall is provided so that the introduction of the cooling water into the heat insulation container and the replacement by the derivation of the heating / cooling water accompanying this can be performed smoothly without mixing each other, provided in the introduction area of the cooling water, By diffusing the introduced cooling water and extending the temperature rising cooling water from a wide area, the temperature rising cooling water is derived at a high temperature without mixing the introduction cooling water.
[0004]
By the way, the partition and the inner container that accommodates the partition have a subtle effect on the introduction and derivation of the cooling water. For this reason, the positions and shapes of the partition walls and the inner container are important for smoothly switching the introduced cooling water and the temperature rising cooling water during the heat insulation accompanying this without mixing each other.
[0005]
Referring to FIG. 1 showing an embodiment of the present invention, the shoulder 1b of the inner container 1 constituting the vacuum double container 10 which is the container body is desirably a relatively large round shape, and the partition wall 4 is shown in FIG. It is reported that it is preferable to provide an appropriate posture in the vicinity of the inside of the shoulder portion 1b as shown in FIG.
[0006]
However, the rounded shape of the shoulder portion 1b of the inner container 1 has difficulty in attaching the partition wall to an appropriate position and posture. A support pipe 22 is provided around the outlet pipe 22 through which the hot cooling water is led out. In order to ensure this support, the outlet tube 22 is supported at two locations, the container port 10 a of the vacuum double container 10 and the bottom of the inner container 1.
[0007]
[Patent Document 1]
Japanese Patent Laid-Open No. 10-71840 (Claims 1 and 2)
[0008]
[Problems to be solved by the invention]
However, because the inner container 1 has errors in the diameter, roundness, and shape of each part due to its molding error, it is difficult for the partition wall 4 supported by the outlet tube 22 and the inner surface of the inner container 1 to be in uniform contact throughout the entire area. In addition, non-uniform gaps that cause the introduced cooling water to intrude into and mix with the temperature rising cooling water being kept warm are likely to occur. In addition, if the inner container 1 containing liquid is distorted by vibrations, sudden start or sudden stop when the automobile is running, the uneven gap is generated or increased. .
[0009]
An object of the present invention is to provide a heat-reserving liquid storage container capable of easily and properly attaching a partition wall and maintaining the state even on the shoulder portion of the inner container of a vacuum double container.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the heat retaining liquid container of the present invention is a heat retaining liquid storage container having a heat insulating structure for heat insulating and storing the stored liquid, and in order to provide a partition inside the container main body, The main feature is that a plurality of attachment pieces formed by bending on the outer periphery of the partition wall, a continuous attachment peripheral wall, or a peripheral wall having a plurality of cuts from the end in the circumferential direction are fitted and welded to the inner surface of the container body. Yes.
[0011]
In such a configuration, the partition wall is fitted and welded to the inner surface of the container main body at the outer peripheral portion thereof, so that it can be easily and surely integrated and attached. It is easy to maintain the initial mounting state. At the same time, the attachment part of the partition wall to the inner surface of the container body is an attachment piece formed by bending the outer periphery of the partition wall, a peripheral wall continuous in the circumferential direction, or a peripheral wall having a plurality of cuts from the end in the circumferential direction. Each has a folding structure at least at the outer periphery of the partition wall to obtain some spring effect in the thickness direction, positioning the fit with the inner surface of the container body by absorbing the error of the mutual shape and dimensions The attachment by welding can be achieved by the relationship between the position and the posture of the street, and the partition wall is not deformed due to the fitting, and the characteristics are not impaired.
[0012]
In a further configuration, the septum has a plurality of smaller diffusion holes around the central through hole, and the mounting piece or notch forms a gap between the septum and the inner surface of the container body.
The partition wall is located in the liquid introduction area of the container body, and the introduction liquid is diffused through a plurality of small diffusion holes around the central through-hole to reach the heat-retained liquid from a wide area and is kept warm through the central through-hole. In the case where the liquid is led out at a high temperature without mixing of the introduced liquid, the container can be inserted between the mounting pieces of the partition wall or by cutting, because the positional relationship between the inner surface of the container body and the partition wall is stable. A gap having a uniform size and shape as set is formed between the inner surface of the main body and the partition wall, and this gap is used as a precise diffusion passage around the outer periphery of the diffusion hole, so that the diffusion region of the introduction liquid As a result, the replacement of the introduced liquid and the derived liquid is achieved smoothly without mixing.
[0013]
In a further configuration, the distance between the bent pieces or the cut width is larger than the diameter of the plurality of through holes,
The required diffusion flow rate is controlled while restricting the introduction so that the introduction liquid intrudes into and mixes with the liquid being kept warm by increasing the gap length corresponding to the width between the bent pieces or the cut width by keeping the gap width small. Can be obtained.
[0014]
In a further configuration, the mounting piece or the mounting peripheral wall is fitted and welded to a substantially straight cylindrical surface around the axis of the container body.
Since it is a cylinder surface that fits just by fitting the bulkhead and the other party is a straight fit and does not have an edge, it can be stabilized in a predetermined position at a predetermined position. Cheap.
[0015]
In a further configuration, the partition wall is a dish shape in which the mounting piece or the rising peripheral wall from the mounting peripheral wall is formed away from the inner container.
Even when the container body is a metal vacuum double container and a partition wall is provided inside the rounded shoulder of the inner container, the mounting piece or the mounting peripheral wall is located away from the partition wall by the amount of the rising peripheral wall. By using the position avoiding the rounded shoulder of the inner container, it can be easily positioned and welded by fitting without the influence of roundness. At the same time, the rising peripheral wall is away from the inner surface of the container body, so that the fitting and positioning of the partition wall with the inner surface of the container body at the time of welding is not complicated or inconvenient. Further, the dish shape increases the deformation strength of the partition wall, and the mutual reinforcing effect with the inner surface of the container body is improved.
[0016]
In a further configuration in which the rising peripheral wall is formed with a step between the mounting piece or the mounting peripheral wall,
The deformation strength of the stepped portion is high, and the overall strength of the bulkhead and the mutual reinforcement effect between the bulkhead and the container body are enhanced. In addition, the deformation due to the fitting between the mounting piece or the mounting peripheral wall and the inner surface of the container main body is not limited to the partition wall and the peripheral wall It is possible to prevent the partition wall from being deformed, and it is also possible to prevent the partition wall from being inclined due to deformation or distortion of the rising peripheral wall.
[0017]
Further objects and features of the present invention will become apparent from the following detailed description and drawings. Each feature of the present invention can be used alone or in combination in various combinations.
[0018]
【Example】
Embodiments of the present invention will be described below with reference to FIGS. 1 to 11 together with some examples to provide an understanding of the present invention.
[0019]
Each of the examples shown in FIGS. 1 to 5, the examples shown in FIGS. 6 to 8, and the examples shown in FIGS. 9 to 11 of the present embodiment includes a vacuum double container 10 as an example of a heat storage container. Adopted in the main body, it is placed in the cooling water circulation path of the engine of the automobile described above as one application example, and the cooling water circulated with the operation of the engine is introduced and the temperature is raised while refluxing. The heated and cooled water stagnated in the inner container 1 after the engine is stopped is kept warm by the space between the inner and outer containers 1 and 2 being the vacuum space 3. On the other hand, natural cooling is performed in the circulation region other than the inner container 1. At the start of the next engine operation, the circulation of the cooling water is also started, and the temperature-raised cooling water that has been kept warm in the inner vessel 1 is led out with the introduction of the cooling water and supplied to the engine at the warming temperature. This helps to ensure a predetermined combustion efficiency from the beginning of the operation by helping the temperature rise at the start of the engine operation. Near the inside of the shoulder 1b in the inner container 1, a partition wall 4 having a diffusion hole 4a for uniformly diffusing the introduced cooling water in the cross-sectional direction of the inner container 1 is provided in a direction crossing the inner container 1, Due to the uniform diffusion of the introduced cooling water, the temperature-warming cooling water being kept in the inner container 1 is not mixed with this as much as possible, so that it can be pushed out and refluxed without lowering the temperature.
[0020]
However, the heat storage container contains various beverages such as tea, coffee and tea, beverages such as sports drinks, and is used or used at that time, for example, an electric pump, a manual pump, a tilt, while keeping warm or cold. It is widely used to pour out, etc., directly drink from the drinking mouth, sucking and drinking with a straw, etc., individually storing multiple types of internal solutions, individually such as one container mouth and upper and lower It is possible to use it individually for drinking and use through the provided container opening. In addition, it is anticipated that new applications will be further developed in the future utilizing the function of a heat-reserving liquid storage container having a partition wall. In addition, the direction of crossing the container body is not limited to the provision of the partition wall, and it may be arranged in parallel with the axis line or may be provided in part depending on the application. Good.
[0021]
The vacuum double container 10 of the present embodiment is a heat insulating container that retains and retains heat, and the inner and outer containers 1 and 2 are made of stainless steel having low heat conductivity because of the relationship between strength and corrosion resistance. However, the present invention is not limited to this, and it may be selected and used according to the purpose of use and the use situation.
[0022]
In addition, the inner container 1 has a gentle curved shape portion 1d whose bottom portion is convex downward and a trunk portion from the curved shape portion 1d, as in the example shown in FIGS. 1 to 5 and the example shown in FIGS. 1c has a rounded portion 1e that is rounded and connected, and the trunk portion 1c is connected to a shoulder portion 1b that rises slightly obliquely toward the mouth portion 1a through a rounded portion 1f that is rounded. The mouth portion 1a has a shape that rises straight from the shoulder portion 1b through a rounded portion 1g having a small roundness, and smoothly introduces and diffuses the cooling water together with the diffusion action of the introduced cooling water by the partition wall 4. Thus, it is possible to ensure smooth outflow and recirculation without mixing of the heated cooling water and the introduced cooling water during heat insulation. Furthermore, the outer container 2 is provided with an enlarged diameter portion 1i having a stepped portion 1h obliquely upward on the outer side at the upper end portion of the mouth portion 1a of the inner container 1 so as to be joined to the outer container 2. The strength when supported by is secured.
[0023]
On the other hand, in the example shown in FIGS. 1 to 5, the outer container 2 is connected from the straight body 2 c to the shoulder 2 b through a small double step 2 d. The shoulder portion 2b becomes a flat portion 70 through a tapered shape portion 80 that rises obliquely at a larger angle than the shoulder portion 1b of the inner container 1 from the step portion 2d toward the mouth portion 2a, and then has an even tighter taper. After having the shape part 80, it reaches the vertical mouth part 2a, and the airtight joining by the welding with the said enlarged diameter part 1i of the inner container 1 is aimed at. Note that the getter 42 for degassing in the vacuum space 3 is attached to the inside of the flat portion 70 as an example, but may be provided at any position within the vacuum space 3. The outer container 2 configured as described above is inclined in the radial direction of the mouth portion 1a of the inner container 1 by the inclination formed by the two tapered portions 80 of the shoulder portion 2b, particularly the inner tapered portion 80 having a large rising angle. With respect to the displacement, the taper-shaped portion 80 and the flat portion 70 on the outer peripheral side support the displacement toward the flat portion bottom side of the inner container 1 with a slight vibration absorption, respectively, and the tensile force is used for the displacement toward the non-bottom portion side. Since the vacuum double container 10 is mounted on an automobile, the inner container 1 into which the cooling water is introduced is subjected to external vibrations and sudden inertia force through the outer container 2. Even if it is received, it can be prevented from being displaced or damaged while preventing vibration.
[0024]
In addition, the outer container 2 in the example shown in FIG. 6 has a tapered shape that is slightly tighter than the shoulder 1b of the inner container 1 through the small rounded part 2e from the upper end of the straight body 2c, but gently rising. After forming the shoulder portion 2b having 80, the small rounded portion 2f leads to the mouth portion 2a to join the mouth portion 1a of the inner container 1. In this case, the rounded portion 2 f exhibits a slight vibration absorbing property for supporting the inner container 1 in the radial direction, and the tapered portion 80 can exhibit a slight centripetal property for supporting the inner container 1 in the thrust direction. A plurality of getters 42 are provided on the upper inner surface of the straight body 2c. The outer container 2 thus configured has a slight elasticity in supporting the mouth portion 1a of the inner container 1 in the radial direction and exhibits a vibration absorbing action. Even if the inner container 1 being introduced is subjected to external vibration or sudden inertia force through the outer container 2, it is prevented from being displaced or damaged while preventing vibration. can do.
[0025]
However, to form the vacuum double container 10, the inner and outer containers 1, 2 may be formed in any shape, and may be combined, but the inner container like the vacuum double container 10 of this example In order to provide the partition wall 4 in the vicinity of the inner side of the shoulder portion 2b, the round portion 1f has not been successfully arranged.
[0026]
Correspondingly, in this embodiment, the partition 4 is provided in the vicinity of the inside of the shoulder 1b having the rounded portion 1f as described above of the inner container 1 in the metal vacuum double container 10. In addition, in order to easily and properly attach the partition wall 4 and to maintain the mounting state, a plurality of mounting pieces 121 such as the example shown in FIGS. The peripheral wall 122 having a plurality of notches 122a in the circumferential direction as shown in FIG. 6 to FIG. 8 and the examples shown in FIG. 9 and FIG. It fits on the inner surface of the inner container 1 of the vacuum double container 10 and is welded as shown by a spot welded portion 123 as one example. However, the welding method is not particularly limited.
[0027]
In this way, in this embodiment, the partition wall 4 is fitted and welded to the inner surface of the inner container 1 at the outer peripheral portion 4g, so that it can be easily and reliably integrated and attached, and the relationship of mutual reinforcement is also thereafter. It is easy to help maintain the initial mounting state of the inner container 1 and the partition wall 4. At the same time, the attachment portion of the partition wall 4 to the inner surface of the inner container 1 has an attachment piece 121 formed by bending the outer periphery of the partition wall 4, a peripheral wall continuous in the circumferential direction or a peripheral wall 122 having a plurality of cuts 122a from the end portion in the circumferential direction. Therefore, each of them has at least a spring effect in the thickness direction by the bent structure at the outer peripheral portion 4g of the partition wall 4 and has a fitting effect with the inner surface of the inner container 1 between each other. The attachment by welding can be achieved in relation to the position and posture as determined by absorbing the errors in shape and dimensions, and the partition 4 can be deformed due to the fitting and the characteristics can be impaired. Absent.
[0028]
The fitting and welding of the partition wall 4 to the inner container 1 as described above are shown in FIGS. 2 and 5 of the example of FIGS. 1 to 5 of the inner container 1, and the examples of FIGS. 6 and 7. Before joining the joining portion 44 as shown in FIG. 6, the partition wall 4 is press-fitted into the upper half of the body portion 1c of the inner container 1 from the joining end that is still open by the attachment piece 121 or the attachment peripheral wall 122 portion. For example, spot welding by pinching from inside and outside can be easily performed. Of course, other welding methods may be employed, or they may be fixed by brazing instead of welding. At this time, the partition 4 is pushed in by pushing a predetermined amount of various edge portions and various surfaces formed by the mounting pieces 121 and the lower ends of the mounting peripheral walls 122 formed at various locations of the partition wall 4 from the joint ends of the joint portions 44. It can be easily and easily pushed into a predetermined position in the inner container 1 for fixing. In this case, the partition wall 4 can be provided with high accuracy by restricting the pushing position and posture of the partition wall 4 with respect to the joining end of the inner container 1 as a reference and restricting the final pushing position and the pushing posture of the pushing tool.
[0029]
Here, the partition 4 in the examples of FIGS. 1 to 5, FIGS. 6 to 8, and FIG. 11 is a smooth exchange in which the introduction liquid and the derivation of the derivation liquid accompanying the introduction do not mix with each other. For this reason, the ceiling portion 4c having the outer peripheral portion 4g has a plurality of smaller diffusion holes 4a around the central through hole 4d, while the mounting pieces 121 in the example of FIGS. As shown in FIG. 5, the notches 122 a in the examples of FIGS. 6 to 8 and the example of FIG. 11 have gaps 124 formed between the partition walls 4 and the inner surface of the inner container 1, respectively. Yes. As a result, the partition wall 4 is positioned in the liquid introduction area of the vacuum double container 10, and thus in the liquid introduction area of the inner container 1, and the introduction liquid is introduced into the plurality of small diffusion holes 4 a around the central through hole 4 d. The contents are diffused and spread from the wide area to the liquid being kept warm, and the liquid being kept warm is led out at a high temperature without mixing of the introduced liquid through the central through hole 4d and the lead-out pipe 22 penetrating the center through hole 4d. Since the positional relationship between the inner surface of the vessel 1 and the partition wall 4 is stable as described above, the inner wall 1 and the partition wall 4 between the mounting pieces 121 of the partition wall 4 or between the inner surface of the inner container 1 and the partition wall 4 by the notch 122a. A gap 124 having a uniform size and shape can be formed, and this gap 124 is used as a precise diffusion path around the outer periphery of the diffusion hole 4a, and the introduction liquid and the lead-out liquid are increased by increasing the diffusion area of the introduction liquid. Change of Ri to be achieved smoothly without mixing.
[0030]
Moreover, in each, the space | interval W of the bending piece 121 and the width | variety X of the notch 122a are set larger than the diameter of the some diffusion hole 4a. In this way, the gap length L corresponding to the interval W of the mounting pieces 121 and the cut width X is increased by the amount that keeps the width Y of the gap 124 small, and the introduced liquid enters and mixes in the liquid being kept warm. It is possible to obtain a necessary diffusion flow rate while restricting such introduction.
[0031]
Moreover, the mounting piece 121 and the mounting peripheral wall 122 are fitted to the inner surface of the body portion 1c forming the substantially straight cylindrical surface portion around the axis of the container body, in this example, the substantially straight cylindrical surface portion of the inner container 1 of the vacuum double container 10. In addition, welding is performed as indicated by the spot welded portion 123. Thus, the mating partition 4 is stabilized at a predetermined position and in a predetermined posture by only mating the partition walls 4 so that the mating partner is an almost straight inner surface of the body portion 1c that does not slip. Therefore, it is easy to weld to a proper position and a proper posture.
[0032]
The partition 4 is further raised from the mounting piece 121 and the mounting peripheral wall 122 as shown in FIGS. 1, 5 and 7 in the example shown in FIGS. 1 to 7 and as shown in FIG. 8 in the examples of FIGS. The peripheral wall 125 is a dish shape formed away from the inner container 1. In this case, even when the container body is a metal vacuum double container 10 and the partition wall 4 is provided inside the shoulder portion 1b having the rounded portion 1f of the inner container 1, the amount of the rising peripheral wall 125 is sufficient. Since the mounting piece 121 and the mounting peripheral wall 122 are located away from the partition wall 4 substantially formed by the ceiling portion 4c, the position where the rounded portion 1f of the shoulder portion 1b in the inner container 1 is avoided is used. As described above, the body portion 1c can be used for easy positioning and welding by fitting without being affected by the rounded portion 1f. At the same time, since the rising peripheral wall 125 is separated from the inner surface of the inner container 1, it becomes irrelevant to the fitting and positioning of the partition wall 4 with the inner surface of the inner container 1 at the time of welding, which complicates and inconveniences the fitting and positioning. I will not bring it. In addition, the dish shape increases the deformation strength of the partition wall 4 and improves the mutual reinforcement effect with the inner surface of the inner container 1.
[0033]
In the example of the partition wall 4 shown in FIGS. 1 to 5, the rising peripheral wall 125 is inclined so that the upper part of the attachment piece 121 is separated from the inner container 1, and the rising peripheral wall 125 itself is inclined along this inclination. As a result, the whole is appropriately separated from the inner container 1 so that the introduced liquid reaches the gap 124 appropriately. However, the outer peripheral portion 4g of the partition wall 4 may be in contact with the inner surface of the rounded portion 1f of the inner container 1 so that the introduced liquid does not reach the outer periphery of the outer peripheral portion 4g. In addition, an annular bead 63 having a substantially trapezoidal cross section that protrudes upward is formed between the formation region of the central through hole 4d and the diffusion hole 4a of the ceiling portion 4c of the partition wall 4 to improve vibration resistance and the inner container 1. The deformation rigidity when it becomes a pressing part at the time of pushing in is increased.
[0034]
The partition 4 in the example of FIGS. 6 to 8 is substantially vertical at a position away from the inner container 1 by having a stepped portion 126 between the rising peripheral wall 125 and the mounting peripheral wall 122 as shown in FIGS. It rises and is connected to the ceiling part 4c, and the ceiling part 4c extends with a gentle upward slope to the vicinity of the central through hole 4d. An annular wall 65 is provided between the inclined portion of the ceiling portion 4c and the central through hole 4d so that vibration resistance is ensured with high deformation strength by the step portion 126. The annular wall 65 is attached by, for example, welding an inward flange portion 65a to the ceiling portion 4c. The gap 124 having a width larger than the plate thickness of the mounting peripheral wall 122 is formed by the amount of the notch 122a that extends to the stepped portion 126. However, the width of the gap 124 can be set freely.
[0035]
In addition to improving the strength of the partition wall 4 as a whole, the stepped portion 126 enhances the mutual reinforcement effect between the partition wall 4 and the inner container 1 fitted with the partition wall 4, and is deformed by fitting the mounting piece or mounting peripheral wall with the inner surface of the container body. It is possible to prevent not only the ceiling portion 4c of the partition wall 4 but also the rising peripheral wall 125 on the outer periphery thereof, and the partition wall 4 is not only deformed, but also the rising peripheral wall 125 is deformed or distorted and the partition wall 4 is inclined. This can also be prevented.
[0036]
In the example shown in FIGS. 9 to 11, the notch 122 a of the mounting peripheral wall 122 is formed only partway in the case of the example shown in FIGS. 6 to 8, and the introduced liquid is between the partition wall 4 and the inner surface of the inner container 1. The number of the diffusion holes 4a formed in the inner row around the central through hole 4d is doubled as compared with the example shown in FIGS. I try not to run out.
[0037]
Separately, the mounting peripheral wall 122 is slightly inclined outward and downward so as to have a press-fitting allowance t as shown in FIG. 9 with respect to the body portion 1c of the inner container 1 within the entire range or the range of formation of the notch 122a. It is formed as follows. As a result, it is welded and attached as shown by the spot welded portion 123 with a slight gap u as shown in FIG. 9 between the barrel portion 1c. In order to divide the mounting peripheral wall 122 at a plurality of locations in the circumferential direction by the notches 122a from the lower end of the inclined portion as described above, the dimension X1 between the notches 122a is made larger than the width X of the notches 122a. The pressure input to the barrel portion 1c of the inner container 1 due to the oblique shape and the biting force on the inner surface of the barrel portion 1c of the mounting peripheral wall 122 are increased so as to prevent misalignment during spot welding. However, the gap u is not particularly necessary although it can be easily press-fitted. This is also effective when applied to the examples shown in FIGS.

【The invention's effect】
According to the main feature of the heat retaining liquid container of the present invention, the partition wall is fitted and welded to the inner surface of the container body at the outer peripheral portion thereof, so that it can be easily and reliably integrated and attached, and thereafter It is easy to maintain the initial mounting state of the container body and the partition wall by helping with the relationship. At the same time, the attachment part of the partition wall to the inner surface of the container body is an attachment piece formed by bending the outer periphery of the partition wall, a peripheral wall continuous in the circumferential direction, or a peripheral wall having a plurality of cuts from the end in the circumferential direction. Each has a folding structure at least at the outer periphery of the partition wall to obtain some spring effect in the thickness direction, positioning the fit with the inner surface of the container body by absorbing the error of the mutual shape and dimensions The attachment by welding can be achieved by the relationship between the position and the posture of the street, and the partition wall is not deformed due to the fitting, and the characteristics are not impaired.
[0045]
According to a further configuration, the partition wall has a plurality of smaller diffusion holes around the central through hole, and the attachment pieces or notches form a gap between the partition wall and the inner surface of the container body. The partition wall is located in the liquid introduction area of the container body, and the introduction liquid is diffused through a plurality of small diffusion holes around the central through-hole to reach the heat-retained liquid from a wide area and is kept warm through the central through-hole. In the case where the liquid is led out at a high temperature without mixing of the introduced liquid, the container can be inserted between the mounting pieces of the partition wall or by cutting, because the positional relationship between the inner surface of the container body and the partition wall is stable. A gap having a uniform size and shape as set is formed between the inner surface of the main body and the partition wall, and this gap is used as a precise diffusion passage around the outer periphery of the diffusion hole, so that the diffusion region of the introduction liquid Introducing liquid due to increase in No more mixing turnover derived liquid to be achieved smoothly.
[0046]
The distance between the bent pieces or the cut width is larger than the diameter of the plurality of through-holes. According to the further configuration, the gap length corresponding to the cut width or the cut width is increased by reducing the gap width. It is possible to obtain a necessary diffusion flow rate while restricting introduction of the liquid so as to intrude and mix in the liquid being kept warm.
[0047]
The mounting piece or mounting peripheral wall is fitted and welded to a substantially straight cylindrical surface around the axis of the container body. According to a further configuration, the fitting is fitted only by fitting the partition wall, and the other party is fitted with a substantially straight fit. Since it is stabilized in a predetermined position at a predetermined position by the cylindrical surface having no edge, it is easy to weld to an appropriate position and an appropriate attitude.
[0048]
According to a further configuration, the partition wall is a dish shape in which a mounting piece or a rising peripheral wall from the mounting peripheral wall is formed away from the inner container. According to a further configuration, the container body is a metal vacuum double container and the shoulder of the inner container is rounded. Even when a partition wall is provided on the inside of the container, the mounting piece or the mounting peripheral wall is located away from the partition wall by the amount of the rising peripheral wall. It can be easily positioned and welded by fitting together without any influence. At the same time, the rising peripheral wall is away from the inner surface of the container body, so that the fitting and positioning of the partition wall with the inner surface of the container body at the time of welding is not complicated or inconvenient. Further, the dish shape increases the deformation strength of the partition wall, and the mutual reinforcing effect with the inner surface of the container body is improved.
[0049]
According to a further configuration in which the rising peripheral wall is formed with a stepped portion between the mounting piece or the mounting peripheral wall, the deformation strength of the stepped portion is high, and the strength of the whole partition and the mutual reinforcement effect between the partition and the container body In addition, it is possible to prevent the deformation due to the fitting between the mounting piece or the mounting peripheral wall and the inner surface of the container body from reaching the rising peripheral wall as well as the outer periphery of the partition wall. It is also possible to prevent the partition wall from being inclined due to deformation or distortion.
