Description

本発明は、冷たい温度を維持する冷却容器に関するもので、より詳細には内部空間に水が受納された構造の容器から成り、冷凍庫等に入れて冷却させても変形や破損されないながら容器の上面に冷気を長時間維持するようにすることで、刺身、果物、冷麺、ビールなどのように冷やしておくことで鮮度が保たれ、味が向上される食物を入れて使用する間、冷気を維持させる冷却機能が備えられた冷却容器に関するものである。 The present invention relates to a cooling container that maintains a cold temperature. More specifically, the present invention includes a container having a structure in which water is received in an internal space. The container is not deformed or damaged even when cooled in a freezer. Keeping the top surface cold for a long time keeps it fresh like sashimi, fruit, cold noodles, beer, etc. The present invention relates to a cooling container provided with a cooling function for maintaining the temperature.

従来に提示された冷却容器は、容器の内部空間に水をたっぷり満たしたり、一定空間の余裕を持ちながら水を少量満たして冷却させるようにしているが、水をたっぷり満たした冷却容器は凍らせると氷の体積が膨脹し、容器の材質によってセラミックやグラスは破損し、また金属や軟質プラスチック製品は
外形が膨張する等の変形が起きて容器として使用することができなくなり、反対に容器の内部空間に一定量程水を少量満たして容器の上部分を上にして凍らせて使用する場合には、氷と容器の上部分間に空間が生じるので、容器の上面に盛られておいた食物に冷気が伝達される効果が相当落ちてしまい、反対に容器をひっくり返して凍らせると、食物を盛って使用する時、最初は容器の上面に冷気がよく伝えられるが、時間の経過によって容器内部空間の氷が溶けて体積が減少し、氷と容器の上部分の間に空間が生じられて容器の上部分にある食物に冷気が伝えられる効果が顕著に低下されることで、冷却容器を使用して食物を摂取する間、食物を冷たくて新鮮に維持しながら食べ物の味をより良くしようとする目的を達成できない問題点があった。
従来の他の冷却容器では、容器本体とは別途に容器受け台を具備してその上面に受納空間を持って氷やドライアイスなどを入れて、その上に容器本体を載せて冷気が容器本体に伝達されるようにしたが、容器本体と氷の間に一定の間隔が開くと共に冷気が側面に流出されるので、冷気の伝達効果が落ち、また冷却容器が２部分に分離されて取扱が不便になり、別途に氷やドライアイスなどを準備しなければならない不便があった。 The cooling containers presented in the past are designed to fill the interior space of the container with plenty of water or to cool it with a small amount of water while maintaining a certain amount of space, but freeze the cooling container filled with plenty of water. The volume of ice and ice expands, the ceramic and glass are damaged by the material of the container, and the metal and soft plastic products are deformed, such as the outer shape of the container, and cannot be used as a container. When a space is filled with a small amount of water and frozen with the upper part of the container facing upward, a space is created between the ice and the upper part of the container. If the effect of transmitting cold air drops considerably, and the container is turned upside down and frozen, the cold air is initially transmitted well to the top of the container when food is used, but as time passes, The ice in the inner space of the container melts and the volume decreases, and a space is created between the ice and the upper part of the container, so that the effect of transferring cold air to the food in the upper part of the container is significantly reduced. While eating food using a container, there has been a problem that the purpose of improving the taste of food while keeping food cold and fresh cannot be achieved.
In other conventional cooling containers, a container cradle is provided separately from the container body, and ice or dry ice is placed on the upper surface of the container with a receiving space. Although it is transmitted to the main body, a certain interval is opened between the container main body and ice, and cold air flows out to the side, so the effect of transmitting the cold air is reduced, and the cooling container is separated into two parts and handled. However, there was an inconvenience that ice or dry ice had to be prepared separately.

以下、本発明による様々な望ましい実施例を添付した図面に基づいてより具体的に説明する。
ここで、下記の各々他の実施例のあらゆる図面で同一な機能を持つ構成要素は同一参照符号を使用する。
図１は、本発明の第１実施例による冷却容器を示した分解斜視図で、図２は、図１の結合状態を示した斜視図で、図３は、図１の結合状態を示した断面図で、図４は、本発明の第１実施例による栓ボルトを示した断面図である。
図１ないし図４に示されたように、本発明の第１実施例による冷却容器は、容器上部２と容器下部３及び弾性板４に大別されており、前記容器上部２と容器下部３を一体に結合する結合ボルト７とパッキング６及び水注入口に締結する栓ボルト５が付加されて構成される。
前記容器上部２は、上面に冷たく涼しいほど持ち味を生かせる食物を盛ることができる一方で、使用中に冷たい容器の上面と室内空気の温度差による結露によって発生した水気が食物に染み込まないように中心部へ行くほど高くなる円板形態で形成されると共に中央部で周辺部へ水気が自然に流れるように円形及び放射状の溝からなる溝部２３が形成され、上面の中央には容器上面の現在温度を表示させる温度表示部２４が形成される。また、容器上部２の下の面には、雌ねじ部が備えられる結合突起２６が中央部に形成され、その側面には容器下部３の水注入口３３と連通されながら水が内部へ注入される水注入通路２６ａが形成される。ここで、容器上部２の上面は、中央部が高くなる形態であるので、冷却容器に刺身を盛る用途で使用する時、千六本を底に敷く必要無しで刺身を外見よくそのまま盛ることができるので、衛生的に使用することができると共に冷気を食物に効果的に伝達することができる。
前記温度表示部２４は、食べる人が温度を見ながら飲食を摂取するので、視覚的に新鮮な感じを持つようにして心理的にも刺身のような食物の味をより一層良くするものであって、その表示方法としては、アナログ温度計やデジタル温度計で表示したり、一定温度で化学的変化により変色するのを利用して温度を判定するサーモカラーなどにすることができる。
前記容器下部３は、前記容器上部２のような大きさの円形箱形態であって、容器の受け台役割をし、中央部へ行くほど次第に低くなる形態であって、中心部には前記容器上部２の結合突起２６と対応する位置に上向きに中空形の突起が突出されて内周面の上部は雌ねじが備えられて結合ボルト７の雄ねじが締結され、下部は結合ボルト７の頭が引込できる直径を有した水注入口３３が形成されて内部に連通される。
前記容器上部２及び容器下部３の構成材料は、錆びたり腐食されないアルミニウムやマグネシウム及びステンレススチールや２種類以上の異種金属を一つに貼ったクラッド(Cｌａｄ)板などのような金属材質やガラス、陶磁器、メラミン樹脂などの非金属材質を使用することができる。特に金属材料を使用すると、表面を金メッキ、銀メッキ、銀ナノ塗装、セラミックコーティング、アノダイジング等人体に無害な表面処理方法で仕上げる。また、前記クラッド板を使用すると、金属に塗装やメッキ及び表面処理した金属材料より表層が厚いので、美麗な状態を半永久的に維持できる長所がある。ここで、容器表面に銀ナノ塗装させると刺身のような食物に存在する細菌を死滅させる坑菌することになる。
前記弾性板４は、前記容器上部２と容器下部３の中間に組立てられるものであって、前記２部材の間に挟まれて２部材の間の内部空間を上下に分離しながら完全に密封させ、中心部は前記容器下部３の水注入口３３から容器上部２の結合突起２６に備えられた水注入通路２６ａを介して冷却空間２５に水を注入することができるように通孔が形成され、その通孔の唇部分に上下両面に突起が突出された円形のパッキング部４１が形成され、円周部分の枠にも上下両面に突起が突出された円形のパッキング部４２が形成されて容器上部２と容器下部３の間に前記弾性板４を介在させ、結合ボルト７で締結すると、容器上部２の冷却空間２５に満たされる水の漏水を完全に防ぐ気密維持の作用を持つ。
前記弾性板４は、弾性復原力と伸縮性があり、また防水性があって水や蓄冷剤に対して寿命が半永久的なゴムなどのような材質を使用する。また、弾性板は金属からなり、弾性復原力を具備したベローズ形態で形成して使用することができ、その他多様に変形して適用できる。
また、前記弾性板４は、弾性材質からなって伸縮作用をし、パッキング部４３により冷却空間２５の水が漏出されることを防止することで一つの部材で２つの作用をする。
前記結合ボルト７は、容器上部２と弾性板４及び容器下部３を一体に結合する締結手段であって、中空形のボルト構造からなって中空の内面に雌ねじが備えられて栓ボルト５が締結される。
前記パッキング６は、前記結合ボルト７に栓ボルト５を締結する時、栓ボルトに挟まれて気密維持の作用を有する。
前記栓ボルト５は、一体に組立てられた冷却容器１の水注入口３３を通じて冷却空間２５に充満するまで水を注入した後、結合ボルト７に締結して密封する。
前記栓ボルト５は、図４に示したような安全バルブ作用を持つ構造から構成されて、不注意や火災などのため、冷却容器が加熱されると冷却空間２５の水が気化されながら内部の圧力が増加して許容圧力以上になると、自動にバルブが開き蒸気を放出して冷却空間２５の圧力を減少させることで、冷却容器の爆発を防止し、事故を防止する。
前記安全バルブが備えられた栓ボルト５の構造及び組立方法は次のようである。
前記結合ボルト７の雌ねじ部に締結される中空形のボルトからなったボルト部５１の内周面内側に直径が小さくなりながら端鍔をなす第１シート部５３ａが形成されて円形のパッキング５６が介在され、前記ボルト部５１の頭部の内周面は雌ねじが備えられて中空形で内周面の入口部分に直径が小さくなりながら端鍔をなす第２シート部５４ａが形成されてパッキング５７が介在される構造の組立ボルト５５が締結される。また、前記ボルト部５１の第１シート部５３ａと組立ボルト５５の第２シート部５４ａに対応して密封するように両端に各々円形突起からなった第１バルブ５３及び第２バルブ５４が形成され、中心軸の外周面にはスプリング５８と組立ボルト５５が挟まれるバルブ部材５２を具備して前記ボルト部５１の雌ねじ部にスプリング５８と組立ボルト５５が一体化されたバルブ部材５２を締結することで、安全バルブが備えられる栓ボルト５から構成される。
ここで、前記バルブ部材５２の第２バルブ５４は、安全バルブの作用をすると共に異質物がボルト部５１の内部に侵入することを防止し、冷却容器１の清潔さ及び美観を維持する。
このように構成される栓ボルト５は、スプリング８によって第１バルブ５３と第２バルブ５４が各々第１シート部５３ａと第２シート部５４ａに密着されて平常時には冷却空間２５の気密を維持していて、もし熱により冷却容器１内部の冷却空間２５に充満してある水が気化されて膨脹すればスプリング８が圧縮されながら第１バルブ５３と第２バルブ５４が同時に外部方向に後退しながら水蒸気が外部に排出されて冷却容器の爆発を防止する。
前記のように構成された本発明の第１実施例による冷却容器１構成要素の結合方法を説明すれば次の通りである。
まず、容器下部３の上面に弾性板４を結合させ、容器上部２を弾性板４の上部に結合した後、結合ボルト７を水注入口３３に締結して容器下部３と弾性板４及び容器上部２を一体に結合すると容器上部２と冷却板４の間の空間は水が充満に注入される冷却空間２５が形成され、冷却板４と容器下部３の間の空間は空気が充満された伸縮空間３１が形成される。次いで、結合ボルト７の中空部を通じて水や蓄冷剤を冷却空間２５に充満に注入し、パッキング６が挟まれた栓ボルト５を前記結合ボルト７に締結して冷却容器１の結合を完了する。
しかし、前記冷却板４は、水の冷却過程と解凍過程で発生する体積の膨脹と縮小作用を吸収する伸縮作用と冷気の伝導を遮断する断熱作用ができるように容器下部３の内部空間を空気が充満した伸縮空間３１に提供するので、冷却容器１を使用する途中、容器下部３の結露を防止するため別途に容器下部３に断熱材を設置しなくても良いので、製造が簡便になる。
そして冷却容器１の冷却空間２５には水の代わりに人体に無害した蓄冷剤や水に蓄冷剤を混合して注入することで、冷却時間を長く維持するようにすることができる。
前記のように構成された本発明の第１実施例による冷却容器１構成要素の作用状態を説明すれば次の通りである。
本発明の第１実施例による冷却容器１を冷凍庫に入れて冷却させると、容器上部２の冷却空間２５に充満した水が冷却されて氷になる間に体積が膨脹するとき、その膨脹される体積程度の伸縮性のある冷却板４が下部方向に押出され容器上部２の変形や破損を防止し、反対に冷却された容器を常温で使用すれば冷却空間２５の氷は、次第に溶けて体積が小さくなっても冷却板４の弾性復原力により上部方向に復元されながら冷却空間２５は常に水と氷で充満された状態を維持し、特に氷は比重が水より軽くて溶ける過程で生じる氷は常に上に浮かぶことになるので、容器上部２の上面に常に冷気がはっきりと伝えられて冷却容器１を使用する間には容器上面の冷却機能を常に同一に維持されるようにする。
そして冷却空間２５には、弾性板４の作用により常に氷や水が充満されていて、運搬中にゆれないので実生活に使用可能な容器製品として認められることができ、使用者に心理的に安定感をあたえる。
また、冷却容器１を使用する中には、温度表示部２４に表示される温度を視覚的に見ながら飲食を摂取するので飲食に対する衛生上の信頼感を与え、同時に心理的に味覚を高める。
そして本発明の第１実施例による冷却容器１は、容器を直接使用する取食者には長時間冷たい温度を維持しながら飲食を新鮮に摂取するようにし、栓ボルト５が安全バルブで構成されるので、製造者及び一般消費者はもちろん、飲食店を運営するサービス提供者にも安全に対する不安感を解消し、本発明の冷却容器１は、各構成部品を溶接や接着する工程が必要なく組立てさえすれば完成品ができる組立式構造であって、各構成部品の製造工程及び組立工程が簡便で、かつ製造原価を大きく節減させることができる利点がある。
図５は、本発明の第２実施例による冷却容器を示す分解斜視図で、図６は図５の結合状態を示した断面図である。
本発明の第２実施例による冷却容器は、容器上部２ａと容器下部３ａ及び弾性板４ａに大別されて構成され、前記容器下部３ａと弾性板４ａの間に設置されるスプリング８と前記容器上部２ａと容器下部３ａ及び弾性板４ａを一体に結合するパッキング６ａと結合ボルト７ａが付加されて構成される。
前記容器上部２ａと容器下部３ａ及び弾性板４ａは、前記本発明の第１実施例による容器上部２と容器下部３及び弾性板４と形態のみ異なり、その基本構造及び作用状態は同一である。
前記容器上部２ａは、四角板形態であって、上面に溝が格子形態で構成されて結露された水が受納される溝部２３が形成され、四つ隅の部分に下方に突出された中空形の突起からなって内周面に雌ねじが備えられた結合突起２６が形成され、その側面に水注入通路２６ａが形成される。
前記容器下部３ａは、上面が開放された四角形の箱形態であって、前記容器上部２ａの結合突起２６に対応する位置に上向きに突出された中空形の突起からなった水注入口３３が形成される。
前記弾性板４は、上面が開放された四角形の箱形態であって、四つ隅の部分には結合ボルト７ａが通過する通孔が形成され、下部にはスプリング８が挟まれる突起が形成され、伸縮性と弾性復原力のあるゴムのような材質からなり、ここに付加して弾性復原力のあるスプリング８が容器下部３ａと弾性板４ａの間に設置されて弾性板４ａの復原力を補強して冷却空間２５の氷が溶けて体積が縮小されるとき、弾性板４ａの復原力を補助する作用をして容器上面に冷気が長時間持続されるようにする。また周辺部には両面に突出されたパッキング部４２が形成されて冷却空間２５の気密を維持させる。
前記パッキング６ａは、前記結合ボルト７ａを締結する時、挟まれて気密を維持する。
前記結合ボルト７ａは、容器上部２ａと弾性板４ａ及び容器下部３ａを一体に結合する締結手段であって、四つで構成されているが、この中で、少なくとも一個は前記本発明の第１実施例による栓ボルト５と同じ構造の安全バルブが備えられる。図７は、本発明の第３実施例による冷却容器を示した分解斜視図で、図８は図７の結合状態を示した断面図である。
本発明の第３実施例による冷却容器１ｂは、容器上部２ｂと容器下部３ｂ及び弾性板４ｂに大別されて構成され、前記容器上部２ｂは更に上部枠２９とパッキング２７及び冷気発散部２１で構成され、そして前記容器上部２ｂと容器下部３ｂ及び弾性板４ｂを一体に結合するパッキング６ｂと結合ボルト７ｂが付加されて構成される。
前記容器上部２ｂと容器下部３ｂ及び弾性板４ｂは、前記本発明の第１実施例による容器上部２と容器下部３及び弾性板４と部分的な構造だけ異なり、その基本構造及び作用状態は同一である。
前記容器上部２ｂは円板形で構成され、上面に飲食が盛られる冷気発散部２１と前記冷気発散部２１を内周面に固定するように中心部が通孔からなった円板形の上部枠２９で構成されて、前記２部材間にパッキング２７を介在し、組立片２８ａと組立ボルト２８で２部材を一体に結合して容器上部２ｂを構成する。このように容器上部２ｂを、２部材を組立てて構成することは、天然材料である玉や大理石のように多様な形態で加工が容易でない材料及びガラスや陶磁器のように破損に弱い材料を比較的製造が容易で、堅固な金属材料と組合して構成すれば容器上部２ｂの冷気発散部２１を多様な材料で色々な形態で製造することが容易であり、高級材料を使用した容器を製造することができ、またデザインを多様化させることができるためである。
前記冷気発散部２１は、ほとんど半球形からなって、上面に結露された水が渡って流れる溝部２３が形成され、前記上部枠２９は、中心通孔が下方に突出されて円筒形になると共に中心部に向かって突起が多数形成され、その下側面にタップ穴が形成され、その側面に水注入通路２６ａが形成される結合突起２６が多数備えられる。
前記弾性板４ｂは、上部が開放された円形の箱形態であって、伸縮性と弾性復原力のあるゴムのような材質からなり、前記上部枠２９のタップ穴に対応する位置に結合ボルト７ｂが通過されるボルト穴が多数備えられ、周辺部には両面に突出されたパッキング部４２が形成されて冷却空間２５の気密を維持させる。
前記容器下部３ｂは、上部が開放された円形の箱形態であって、前記上部枠２９のタップ穴に対応する位置に結合ボルト７ｂが通過されるボルト穴が多数備えられる。
前記結合ボルト７ｂは、容器上部２ｂと弾性板４ｂ及び容器下部３ｂを一体に結合する締結手段であって、少なくとも一個は前記本発明の第１実施例による栓ボルト５と同じ構造の安全バルブが備えられる。
図９は、本発明の第４実施例による冷却容器を示した分解斜視図で、図１０は図９の結合状態を示した断面図である。
本発明の第４実施例による冷却容器１ｃは、容器上部２ｃと弾性板４ｃ及び前記弾性板４ｃを容器上部２ｃに固定させながら受け台になる容器下部３ｃから構成される。
前記容器上部２ｃは、食物を盛る部分であって、中心部はほとんど半球形態からなり、下部に水が満たされて冷却される冷却空間が形成され、円形枠の内側から下方に垂直延長された円筒の外周面は雄ねじ部２１ａが備えられて容器下部３ｃの雌ねじ部３５とねじ結合し、その下段面にはパッキング溝が形成されて弾性板４ｃのパッキング部４２が挟まれる。
前記容器上部２ｃは、アルミニウム、マグネシウム、ステンレススチール、クラッド板等金属材料や陶磁器、セラミック、合成樹脂、ガラス、玉、石等多様な材料で形成することができ、金属や合成樹脂などの材料には表面処理を施したり、塗装をして高級なイメージを提供することによって味覚を高めることかできる。
前記弾性板４ｃは、前記容器上部２ｃの雄ねじ部２１ａに対応する大きさの円板形で構成されて、中心部が上部方向に若干隆起されながらその下部に伸縮空間を与え、下部面には弾性板４ｃの垂れを防止しながら弾性復原力を向上させるスプリング８が挟まれる突起が形成され、枠から上向きに短く折曲されたパッキング部４２が形成されて前記容器上部２ｃのパッキング溝に挟まれて容器上部２ｃの冷却空間２５を完全に密閉させる作用をし、また伸縮性と弾性復原力及び防水が可能なゴムや合成樹脂などの材料からなる。
前記容器下部３ｃは、下部が塞がった円筒形であって、内周面に雌ねじ部３５が形成され、前記容器上部２ｃの雄ねじ部２１ａに締結して前記弾性板４ｃを容器上部２ｃに固定させて容器上部２ｃの冷却空間２５を密閉させ、同時に容器上部３ｃと弾性板４ｃと容器下部２ｃを一体に結合して冷却容器１ｃとして構成されるようにする。
図示しなかったが、容器上部を堅固な材質で形成し、容器下部を伸縮性と弾性復原力を備えた材質を利用して一体に構成することによって、弾性板を別途に具備しなくても冷却空間の水が冷却されて膨脹したり氷が溶けながら収縮される時、弾性材質の容器下部が膨脹と収縮をする構造として形成することもできる。
本発明の第４実施例による構成要素の結合方法はまず、容器上部２ｃをひっくり返して置いて水や蓄冷剤を充満に満たした後、容器上部２ｃの下の面に弾性板４ｃを被せて容器下部３ｃをねじ締結して冷却容器１ｃの組立を完了する。
このように備えられた冷却容器１ｃを冷凍庫で冷却させて冷却空間２５の水を凍らせると冷却空間２５の水が冷却する過程で体積が膨脹しながら弾性板４ｃが下部に膨脹されて氷の膨脹体積程度を吸収するので、容器上部２ｃの破損や変形が起こらなく、容器上面に食物を盛って使用する中に冷却空間２５の氷が徐々に溶けながら冷却空間２５には氷と水が混在される過程で体積が収縮するとその体積ほど弾性板４ｃが上に復元しながら容器上部２ｃの冷却空間２５は常に水と氷に充満し、特に氷は水上に浮かぶため、容器上面に常に冷気が効率的に伝えられるように作用する。
図１１は、本発明の第５実施例による冷却容器を示した分解斜視図で、図１２は図１１の結合状態を示した断面図である。
本発明の第５実施例による冷却容器１ｄは、ビールカップ構造であって、容器上部２ｄと弾性板４ｄ及び前記弾性板４ｄを容器上部２ｄに固定させながら受け台になる容器下部３ｄで構成される。

ところが製造上の便宜のため、周辺部を２重構造で形成しなくて冷却空間２５を容器上部２ｄの下部にのみ形成することができる。
前記弾性板４ｄは、下部が開放された円形箱形態であって、中心部に円形突起が形成されて弾性板４ｄの垂れを防止し、弾性復原力を向上させるスプリング８が挟まれ、枠は円周方向に短く延長されるパッキング部４２が形成されて容器上部２ｄの下段部と容器下部３ｄの内部底面の間に介在されて冷却空間２５の漏水を防止する気密維持作用をし、前記容器上部２ｄの下部に結びついてその上部には冷却空間２５を与え、その下部には伸縮空間を与えて伸縮性と弾性復原力のあるゴムや合成樹脂などの材料から構成される。
前記容器下部３ｄは、ガラスなどの材料から成り、上部が開放された円形の蓋形態で形成されて内周面に雌ねじ部３５が形成され、前記容器上部２ｄの雄ねじ部２１ａに締結して前記弾性板４ｄを容器上部２ｄに固定させて容器上部２ｄの冷却空間２５を密閉させると共に容器上部３ｄと弾性板４ｄと容器下部２ｄを一体に結合して冷却容器１ｄとして構成されるようにする。
図１３は、本発明の第６実施例による冷却容器を示した分解斜視図で、図１４は図１３の結合状態を示した断面図である。
本発明の第６実施例による冷却容器１ｅは、容器上部２ｅと弾性板４ｅ及び前記弾性板４ｅを容器上部２ｅに固定させながら受け台になる容器下部３ｅで構成される。

前記弾性板４ｅと容器下部３ｅの構造は、前記本発明の第５実施例による弾性板４ｄと容器下部３ｄの構造と同一であり、弾性板４ｅと容器下部４ｅの間にスプリング８が設置されて弾性板４ｅの垂れを防止しながら弾性復原力を補完する。
図１５は、本発明の第７実施例による冷却容器を示した分解斜視図で、図１６は図１５の結合状態を示した断面図である。
本発明の第７実施例による冷却容器１ｆは、容器上部２ｆと弾性板４ｆと前記弾性性板４ｆを容器上部２ｆに固定させながら受け台になる容器下部３ｆ及び容器蓋９ｆで構成される。
前記容器上部２ｆは、食物を盛る部分であって、円形容器の形態で形成され、周辺部は内部が空いている２重構造で構成されて内部空間に水や蓄冷剤が満たされる冷却空間２５が形成され、外側壁の内部には透明で弾性復原力を持った断熱材１２が設置されて弾性板４ｆの作用を補助しながら外面の結露を防止し、上段部に容器上部２ｆより直径が小さな円周面に雄ねじ部２１ｂが形成されて容器蓋９ｆが締結され、下段部の外周面に容器上部２ｆの外径より小さい直径を持った雄ねじ部２１ａが形成されて容器下部３ｅの雌ねじ部３５とねじ結合される。ところが前記上段部に形成される雄ねじ部２１ｂは、二条ねじまたは三条ねじで形成して容器蓋を速かに開け閉めすることが出来る。
前記弾性板４ｆと容器下部３ｆの構造は、前記本発明の第５実施例による弾性板４ｄと容器下部３ｄの構造と同一であり、弾性板４ｆと容器下部４ｆの間にスプリング８が設置されて弾性板４ｆの垂れを防止しながら弾性復原力を補完する。
前記容器蓋９ｆは、円形の蓋形態で形成され、外径が前記容器上部２ｆの外径と同一で、内面に雌ねじ部９１が備えられて前記容器上部２ｆの雄ねじ部２ｂにねじ締結されて容器上部２ｆの内部空間を密閉し衛生的に食物を長時間冷たく保管するようにする。
ところが、前記容器蓋９ｆは、容器上部２ｆのように、内部に冷却空間２５を形成し、水や蓄冷剤を満たし冷却して使用し、容器内部に盛られた食物の冷却維持時間をより長時間持続させることができる。また、容器蓋９ｆには開閉される空気引き通路を形成して容器蓋９ｆが閉められた状態で内部空間の空気が冷たくなると、空気の体積が収縮されながら容器蓋９ｆが軽い力で開けられない時、空気引き通路を開いて容易に容器蓋９ｆが開けられるようにする。
図１７は、本発明の第８実施例による冷却容器を示した分解斜視図で、図１８は図１７の結合状態を示した断面図である。
本発明の第８実施例による冷却容器１ｇは、容器上部２ｇと弾性板４ｇと前記弾性板４ｇを容器上部２ｇに固定させながら受け台になる容器下部３ｇ及び容器蓋９ｇで構成される。
前記容器上部２ｇの構造は、前記第７実施例の容器上部２ｆと構造が同一であり、ただし上段部に容器上部２ｇの外径と同一な外周面に雄ねじ部２１ｂが形成されて容器蓋９ｇが締結されることが異なる特徴であり、前記雄ねじ部２１ｂは二条ねじまたは三条ねじで形成して容器蓋９ｇを速かに開け閉めすることが出来る。
図１９は、本発明の第９実施例による冷却容器を示した分解斜視図で、図２０は図１９の結合状態を示した断面図である。

図２１は、本発明の第１０実施例による冷却容器を示した分解斜視図で、図２２は図２１の結合状態を示した断面図である。
本発明の第１０実施例による冷却容器１ｉは、容器上部２ｉと容器下部３ｉ及び弾性材４ｉに大別されて構成され、前記容器下部２ｉの水注入口を塞ぐ安全バルブが備えられる栓ボルト５ｃが付加されて構成される。
前記容器上部２ｉは、冷麺のように盛る容量が比較的多い食物を盛られるように内部が深い容器形態で形成される。
図示しなかったが、冷却容器の外面に温度表示部を装着して使用する中に、温度を確認しながら視覚的に涼しさを与えるように構成される。
前記容器下部３ｉは、前記容器上部２ｉの下部で結合されて内部に水が満たされる冷却空間２５を提供することによって、中心部に結合ナット３６が設置されて栓ボルト５ｉが締結され、内部底面に弾性材４ｉが接着される。
前記弾性材４ｉは、弾性復原力と防水性及び断熱性を備えている材料からなり、前記容器下部３ｉの内部底面に接着材で完全に密着するように接着して内部底面に水が染み込むことを防止し、容器下部３ｉを断熱させることによって、冷却容器を冷凍庫に凍らせて常温で使用する中に、容器下部３ｉの外面に結露が発生するのを防止し、下部に冷気が発散されるのを防止して冷却持続時間を延長する。また、前記弾性材４ｉは、冷却空間２５の水が凍って体積が膨脹すれば収縮し、氷が溶けて水に還元される過程で、体積が縮小されると復元して冷却空間２５には常に氷に充満されるあるいは氷と水が混在された状態で充満され、容器の上面には飲食を盛って使用する中には常に冷気がいつも同一に維持されるようにする。
ここで、前記弾性材４ｉは、ゴムや合成樹脂などのように弾性復原力及び伸縮性のあるゴムや軟質プラスチックなどの材料を使用して、下の面にエンボッシング形態で多数の突起を形成して容器下部３ｉの内部底面に接着して構成することができる。
前記栓ボルト５ｉは、中空形の無頭ボルト形態であって、中空内部の一段は、直径が小さくなりながら端鍔をなすシート部５３ｂが形成されるボルト部５１ａが形成され、前記ボルト部５１ａのシート部５３ｂに丸いパッキング５６ａを案着させ、螺糸山のない丸い頭ボルト形態として先端部に横方向のフィン穴が形成されるバルブ５３ｃを前記ボルト部５１ａに挿入した後、前記バルブ５３ｃの外周面にスプリング５８ａとウォッシャー５９を順次に嵌め込んでフィン穴に分割ピン５９ａを打ち込んで固定してなる安全バルブから構成される。
ここで、前記バルブ５３ｃの丸い頭の外面と容器下部３ｃの下の面は端鍔の部分がないように水平面を維持するようにして境界部に異質物が入ることを防止し、美観を良好に維持するようにする。
前記のように構成された本発明の第１０実施例による冷却容器の結合方法を説明すれば次の通りである。
まず、容器下部３ｉの内部底面に水が染み込まれないように弾性材４ｉを完全に付着した後、容器上部２ｉを重なっておいて周辺部を材質によってアルゴン溶接や接着剤などの方法で結合した後、結合ナット３６の通孔を通じて水や蓄冷剤を冷却空間２５に充満に注入し、栓ボルト５ｉを締結して密封すると、冷却容器１ｉの組立が完成される。
前記のように構成された本発明の第１０実施例による冷却容器の作用状態を説明すれば次の通りである。
冷却容器１ｉを冷凍庫に入れて冷却させると冷却空間２５に充満された水が冷却されながら体積が膨脹される時、弾性材４ｉは、その膨脹される体積ほど下部方向に収縮されながら容器上部２ｉの変形や破損を防止し、反対に冷却された冷却容器１ｉを常温で使用すれば、冷却空間２５の氷は次第に溶けながら体積が減ると弾性材４ｉは上部方向に復元されるので、冷却空間２５は冷却されている時は氷で、氷が溶ける過程では水と氷が混在された状態で常に充満し、特に、氷は水より比重が小さくて水上に浮かぶようになるので、使用の中には容器の上面に常に冷気が効率的に伝達される。
図２３は、本発明の第１１実施例による冷却容器を示した分解斜視図で、図２４は図２３の結合状態を示した断面図である。
本発明の第１１実施例による冷却容器１ｊは、容器上部２ｊと容器下部３ｊと伸縮部１０及び栓１１とから構成される。
前記容器上部２ｊは中心部へ行くほど次第に高くなる形態であって、その表面に放射状及び円形の溝からなった溝部２３が形成されて結露により発生した水気が流れる通路になって容器上面に盛って置いた食物に水気が染み込むのを防止する。また、容器下部３ｊと結合された周辺部の断面を中心部より薄くした伸縮部２０を形成して冷却空間が凍りながら膨脹する時、垂直方向に膨脹される部分を吸収して容器の上面や下の面の変形を防止する。
前記容器下部３ｊは、受け台役割をするものであって、側面に水平方向に弾性復原力のあるベローズ形態の伸縮部１０が形成されて冷却空間２５の水が冷却されながら体積が膨脹すれば伸縮部１０も水平方向に膨脹され、氷が解凍されながら体積が収縮すれば伸縮部１０も収縮されて冷却により容器上部２ｊ及び容器下部３ｊが変形されるのを防止する。
ここで、前記伸縮部１０及び伸縮部１０の入口部分である水注入口３３は、成形工法とデザインによって冷却容器の下部分や構造上適合した部分に配置する。
前記栓１１は雌ねじが備えられて前記伸縮部１０の先端に形成された雄ねじ部に締結して冷却空間２５を密封する。
図示しなかったが、容器上部の上面を被さる容器蓋を具備し、容器上面を密閉させて冷却容器の冷気を長く保存し、移動が便利であるように構成することができ、前記容器蓋は冷却容器に回動自在が可能であるように固定して設置することができる。
本発明の第１１実施例による冷却容器１ｊの製造方法及び作用効果は次の通りである。
容器上部２ｊと容器下部３ｊ及び伸縮部１０が一体に構成される冷却容器１ｊは、別途に弾性部材を使用しなく、材質自らの伸縮性を利用して製品として製造することができ、その一例としては合成樹脂特に、PET(ＰｏｌｙｅｔｈｙｌｅｎｅＴｅｒｅｐｈｔｈａｌａｔｅ)などのような材質を使用してブローモルディング(中空成形法)工法で製造すると低価で大量生産が可能になり、刺身を盛って食べたり、販売店で陳列するのに使用可能な使い捨て冷却容器として使用することができ、冷却空間２５に水を入れて冷却させた後、ピクニックなどに行く時、持参して野外で冷却容器１ｊに食物を盛って新鮮に食べることができるようにし、使用後に、氷が溶けると冷たい飲み水としても使用することができる等、多様な目的に使用することができる。
また、本発明の第１１実施例による冷却容器１ｊは、冷却空間２５に水や蓄冷剤を注入した後、栓１１を締結して冷凍庫で冷却させて食物を盛って使用する過程で二つの伸縮部１０、２０のようにあらかじめ特定に形成された部分が膨脹と収縮をしながら容器本来の形態が大きく変形されないようにする。
詳しく説明すると、本発明の第１１実施例による冷却容器１ｊは容器の材質特性を利用して容器の特定部分が伸縮が容易にするものの、冷却と解凍過程で容器の形態を維持する構造で構成されたことが特徴である。
図２５は、本発明の第１２実施例による冷却容器を示した分解斜視図で、図２６は図２５の結合状態を示した断面図である。
本発明の第１２実施例による冷却容器１ｋは、容器上部２ｋと容器下部３ｋ及び弾性チューブ４ｋと、容器下部３ｋの水注入口３３を塞ぐ栓ボルト５ｋで構成される。
前記容器上部２ｋは、上面に食物が盛られる部分であって、四角板形態で形成され、上面に多数の突起からなった突出部２２が形成されて結露による水気が食物に染み込まないようにする。
前記容器下部３ｋは、上部が開放された四角形箱形態であって、前記容器上部２ｋの受け台役割をすると共に内部空間に冷却空間２５を提供しながら弾性チューブ４ｋが内在され、２重になった２重構造であって、その内部空間が真空室３２で構成されて伝導及び対流作用を遮断しながら断熱作用を有するので、容器下部３ｋ外面の結露を防止し、一側面には中空の内周面に直径が小さくなりながら端鍔をなし、これに延長して外向に短く垂直折曲される端鍔部３３ａが形成され、内周面に雌ねじが備えられる水注入口３３が形成されて栓ボルト５ｋが締結される。ところが前記水注入口３３は、冷却容器の材質とデザイン及び製造工法によって瓶のくちばし形態で長く延長して作ることもできる。
前記弾性チューブ４ｋは、伸縮性と弾性復原力及び防水性をもった材質からなり、長いチューブ形態として入口部分が円形に開放されて、その端部が外向に垂直折曲され、次いで内側に短く垂直折曲されるパッキング部４３が形成されて前記水注入口３３の端鍔部３３ａに挟まれて栓ボルト５ｋを締結すると気密を維持するようにする。
また、前記弾性チューブ４ｋは、弾性材質からなって伸縮するので、冷却容器を冷凍庫で凍らせて、冷却空間の水が凍りながら体積が膨脹される時起きる破損や変形を防止し、パッキング部４３により冷却空間２５の水が漏出するのを防止して入口部分を栓ボルト５ｋとして容器下部３ｋの水注入口３３に固定することによって、弾性チューブを冷却空間で一定位置に固定させる３つの作用を同時にすることが大きい特徴である。
ところが、弾性チューブを内部に空気を含んで独立的な形態で形成して冷却空間に内在させると、冷却容器の置かれた状態によって冷却空間でとどまる位置が一定ではないので、場合によっては、冷却空間の上面近くとどまった状態で容器を冷却させると弾性チューブに遮断により容器上面に冷気が円滑に伝達できなくなり、また、弾性チューブが水平方向にあまり片方に偏った状態で冷却されると冷却空間に満たされた水が凍りながら膨脹する時、弾性チューブが位置しない部分が氷の膨脹を吸収できなくなって冷却容器の変形や破損が起きる可能性があるとの問題点がある。
前記栓ボルト５ｋは、外周面に雄ねじが備えられる無頭ボルト形態で形成されて水注入口３３に締結され冷却空間２５を完全に密封する。
図示しなかったが、別途の安全バルブを容器上部２ｋや容器下部３ｋに設置することができ、また温度表示部を装着して容器上面の冷却温度を表示して使用者に新鮮な感覚を感じるようにして味覚をより良くできる。
本発明の第１２実施例による冷却容器１ｋの結合方法は次の通りである。
まず、真空室３２が備えられる容器下部２ｋと容器上部３ｋを溶接や接着などの方法で一体に結合し、水注入口３３を通じて水や蓄冷剤を冷却空間２５にほとんど充満に注入し、弾性チューブ４ｋを冷却空間２５の内部に挿入した後、栓ボルト５ｋを締結して冷却容器１ｋとして完成する。
本発明の第１２実施例による冷却容器１ｋの作用効果は次の通りである。
冷凍庫から前記冷却容器２ｋを冷却させて容器上面に食物を盛って使用する中に、冷却空間２５の氷が溶けても前記本発明の第１実施例による冷却容器１の作用効果と同一に使用する時は、常に容器上面に冷気が完全に伝達されて、始終ほとんど同じ温度を維持する。また、本発明の第１２実施例による冷却容器１ｋは、容器本体の内部に弾性チューブ４ｋを、水注入口３３を通じて挿入し、栓ボルト５ｋを締結すると冷却容器が完成される簡単な構造からなって、製造が非常に容易で製造原価を節減できる。
図２７は、本発明の第１３実施例による冷却容器を示した分解斜視図である。
本発明の第１３実施例による冷却容器１ｋ１は、容器上部２ｋ１と容器下部３ｋ１及び弾性チューブ４ｋ１と、容器下部３ｋ１の水注入口３３を塞ぐ栓ナット５ｋ１から構成される。
本発明の第１３実施例による冷却容器１ｋ１の基本構造は、前記本発明の第１２実施例による冷却容器１ｋと同一であり、たたし、具体的な形態が一部異なることが特徴である。
前記容器上部２ｋ１は、食物が盛られる部分であって、円形容器形態で形成されて、上面に放射状形態の溝部２３が多数形成されて結露による水気が食物に染み込まないようにする。
前記容器下部３ｋ１は、前記容器上部２ｋ１の受け台役割をし、内部空間に冷却空間２５及び弾性チューブ４ｋが内在され、一側から長く突出された中空形の管になって冷却空間２５に水を注入し、弾性チューブ４ｋ１の入口部分が固定される水注入口３３が形成される。前記水注入口３３の段部には雄ねじ部が形成されて栓ナット５ｋ１が締結される。
前記弾性チューブ４ｋ１は、伸縮性と弾性復原力及び防水性をもった材質からなり、長いチューブ形態であって、入口部分が外向に垂直折曲され、次いで内側に短く垂直折曲されるパッキング部４３が形成されて前記水注入口３３の唇部分に挟まれて栓ナット５ｋ１を締結すると気密を維持するようにする。
前記栓ナット５ｋ１は、内周面に雌ねじが備えられた蓋形態で形成され、水注入口３３に締結されて弾性チューブ４ｋ１のパッキング部４３を押持するので、冷却空間２５に満たされた水の漏水を防止する。
図２８は、本発明の第１４実施例による冷却容器を示した分解斜視図で、図２９は図２８の結合状態を示した断面図である。
本発明の第１４実施例による冷却容器は、容器上部２ｍと容器下部３ｍ及び弾性チューブ４ｍと容器下部３ｍの下の面に形成された水注入口３３を塞ぐ栓ボルト５ｍとから構成される冷却容器１ｍと、容器上部２ｍと容器下部３ｍ及び弾性チューブ４ｍと容器下部３ｍの下の面に形成された水注入口３３を塞ぐ取っ手が付いた栓ボルト５ｍ１で構成されて前記冷却容器１ｍに被せて使用する容器蓋９で構成される。
前記容器上部２ｍは、中心部へ行くほど若干低くなる皿形態で、冷却容器１ｍでは上面に食物が盛られる部分であり、容器蓋９では冷気を下部へ伝達して冷却容器１ｍに盛られた飲食に冷気を提供してくれる。
前記容器下部３ｍは、中心部へ行くほど深くなる円形の容器形態で形成され、前記容器上部２ｍの受け台役割をし、内部に冷却空間２５を提供しながら弾性チューブ４ｍが内在され、２重になった２重構造であって、その内部空間が真空室３２からなり、伝導及び対流作用を遮断しながら断熱するので、容器下部３ｍ外面の結露を防止し、下部面には中空で形成されて内側に直径が小さくなりながら端鍔をなし、これに延長して外向に短く垂直折曲される端鍔部３３ａが形成され、内周面に雌ねじが備えられる円形の通孔からなった水注入口３３が形成されて栓ボルト５ｍが締結される。
前記弾性チューブ４ｍは、伸縮性と弾性復原力及び防水性をもった材質からなり、きのこ形態のチューブで形成され、入口部分が円形に開放されてその段部が円周方向に垂直折曲され、次いで内側に短く垂直折曲されるパッキング部４３が形成されて前記水注入口３３の端鍔部３３ａに挟まれ、栓ボルト５ｍを締結すると気密を維持する。
図示しなかったが、前記弾性チューブ４ｍの内部にスプリングを設置して弾性チューブ４ｍの復原力を補強して冷却空間２５の氷が溶けて体積が縮小されるとき、弾性チューブ４ｍの復原力を補助する作用をして容器上面に冷気が長時間持続されるようにする。
前記栓ボルト５ｍは、外周面に雄ねじが備えられた無頭ボルト形態で形成され、水注入口３３に締結されて冷却空間２５を密封する。
一方、前記容器蓋９に締結される栓ボルト５ｍ１は、外周面に雄ねじが備えられて、一段に取っ手が付いた形態で形成され、容器蓋９の水注入口３３に締結される。
図示しなかったが、前記冷却容器１ｍと容器蓋９を被せた後、食物を盛って移動したり冷気を長く保存するため、冷却容器１ｍと容器蓋９に各々突起部が前記突起部に挟まれるようにヒンジ連結して回動自在される輪が取り付けられて開閉装置を装着する構造として形成できる。
また、図示しなかったが、別途の安全バルブを容器上部２ｍや容器下部３ｍに設置することができ、また温度表示部を装着して容器上面の冷却温度を表示することで使用者に新鮮な感覚を感じるようにして信頼感を与え、食べ物の味を高めることができる。

本発明の第１５実施例による冷却容器１ｎは、容器上部２ｎと容器下部３ｎ及び弾性チューブ４ｎに大別されて構成され、前記弾性チューブ４ｎの内部に設置されるスプリング８と容器下部３ｎの下の面に形成された水注入口３３を塞ぐ栓ナット５ｎが付加されて構成される。
前記容器上部２ｎは、中心部へ行くほど高くなる半球形態で形成され、上面には多数の突起からなった突出部２２が形成されて刺身のような食物が突出部２２に載せられることで結露により生じた水気が染み込まなく流れるようになっている。
前記容器下部３ｎは、円板形態で形成され、中心部は上部方向に深くなりながらその中心部は、円形通孔となって内周面が外部に突出されながら、その外面に雄ねじが備えられた水注入口３３が形成されて栓ナット５ｎが締結される。
前記容器上部２ｎと容器下部３ｎは、アルミニウム、マグネシウム、ステンレススチール、クラッド板等金属材料や陶磁器、セラミック、合成樹脂、ガラス、玉、石等多様な材料で形成することができ、金属や合成樹脂などの材料には表面処理をしたり銀ナノ塗装及びいろいろな工法の塗装をして高級なイメージを提供することによって、使用者の味覚を高めることができる。特に銀ナノ塗装をすると、坑菌機能があるので、刺身のように生で食べる飲食を衛生的に摂取することができるようにする。

ここで、前記弾性チューブ４ｎは、冷却容器の大きさや形態によって多数を具備して冷却容器に内在させることができ、前記容器上部２ｎをガラスなど透明な材質を使用する場合には、弾性チューブ４ｎを花模様などの文様にデザインを多様で華麗にすることで、使用者が容器内部の冷却された模様と華麗な文様を見れば飲食の新鮮さを感じられると共に味覚をはるかに良くする。
前記スプリング８は、弾性チューブ４ｎの内部に設置されて弾性チューブ４ｎの復原力を補強し、冷却空間２５の氷が溶けて体積が縮小されるとき、弾性チューブ４ｎの復原力を補助する作用をして容器上面に冷気が長時間持続されるようにする。
前記栓ナット５ｎは、容器下部３ｎの水注入口３３に締結されるものであって、プラスチックのような軟質の材料からなった内部材５９と陶磁器やガラスのような外部材からなった２重構造で構成されて、容器下部３ｎの材料が陶磁器やガラスなどからなった場合に、やはり同じ材料からなった栓ナット５ｎを締結すれば雌ねじ部と雄ねじ部間の摩擦力が弱いので、緊密に締結されなく、自ら解かれることを防止する。

このように構成される弾性チューブ４ｐは、弾性を持ったゴムのような材質からなり、製造過程で上部と下部を別途に成形した後、２部材を接着剤で接合して一体に結合し、バルブ体４４の針穴を通じて弾性復原力を維持するに必要な適正量の空気を注入し、前記バルブ体４４の針穴は、弾性体４５の圧縮力によりバルブ体４４の針穴を密封する。
また、前記弾性チューブ４ｐの空気注入方法において、チェックバルブ形態で内部に板膜を具備した空気注入口を設置して、外部から内部には空気が注入され、内部から外部には空気が排出されなく、遮断される構造で形成することができる。
そしてバルブ体４４を弾性のゴム系統の材質を利用して針穴をあらかじめ形成しなく、空気注入装置の針を挿入して強制的に穴をあけて空気を弾性チューブの内部に注入した後、針穴に接着剤を投入して完全に密閉させることができる。

本発明の第１７実施例による冷却容器１ｑの構成要素は、本発明の第１５実施例による冷却容器１ｎとその構成と作用効果が同一であり、但し容器上部２ｑの上面が周辺部の枠と中心部の半球形態が結合した形態であって、上面の中心部には多数の突起からなった突出部２２が形成されて刺身のような食物が突出部２２に盛られながら結露により生じた水気が染み込まないで流れるようになっている。

ところが前記冷却容器部２００の固定板１０４と熱電素子１０１と断熱材１０２と熱交換片１０３は、放熱部３００の上部に含んで構成することができる。
前記容器上部２ｒは、食物を盛る部分であって、上面に放射状形態の凹溝からなった溝部２３が備えられて結露された水が流れるようにすることによって水気が食物に染み込まないようにする。
前記容器上部２ｒは、図４０ないし図４２に示したように、上面にビールのような酒が入った瓶１３や皿１４やカップ１５のように涼しい飲食を盛る容器を載せて冷却できるように多数の溝からなった収納部２３ａを形成することができ、前記収納部２３ａを除いた冷却空間２５には、図４０に示したような断熱材１２を設置して不必要な冷気の流出を防止して収納部２３ａの冷却効率を向上させる。

前記断熱材１０２は、中心部に熱電素子１０１が挿入される通孔が形成され、発熱部の熱気が吸熱部に接した容器下部３ｒに伝導されないようにする。
前記熱電素子１０１は、前記断熱材１０２の中央部に挟まれる平板片形態であり、吸熱部が上面に位置し、発熱部が下の面に位置して直流電源が印加されるとペルティエ効果が発生して上面に冷気が発散され、下の面に熱気が発生する。
前記熱電素子１０１は、ペルティエ効果を利用したものであって、ペルティエ効果は２種類の金属端を接続させて、ここに電流を流せば、電流方向によって一側端子は吸熱し、他側端子は発熱を起こす現象である。２種類の金属代りに電気伝導方式が異なるビスマス(Ｂｉ)、テルル(Ｔｅ)等、半導体を使用すると効率性の高い吸熱及び発熱作用のあるペルティエ素子が得られる。この熱電素子１０１は電流方向によって吸熱と発熱の転換が可能であり、電流量によって吸熱と発熱量が調節される特性がある。
前記固定板１０４は、熱電素子１０１の発熱部で発生する熱を冷却させることができるように、熱伝導性が良いアルミニウムなどのような材質を使用し、冷却容器部２００の受け台作用を有する。

以上の放熱部３００の構成要素において、受け台１０８の内部に放熱ファン１０７と放熱板１０６と電源供給部を設置し、また受け台１０８の側面に制御部と温度表示部が装着される。
以上で放熱部３００の構成部品の装着位置や構造は、冷却容器の形態によって多様に変更設置することができる。
また、電源供給部を充電式に形成することができるが、両側端子を直接接触させて接点方式で充電したり、充電装置の１次コイルで発生した磁場がバッテリー部分２次コイルに誘導されて電流を供給する電磁気誘導を通じて電流を流れるようにする無接点充電方式で充電して電源を供給することができる。
本発明の第１８実施例による冷却容器１ｒの作動過程と作用効果を調べて見ると次の通りである。
まず、放熱部３００の上面に冷却容器部２００を載せて電源供給部を通じて電流を印加させると熱電素子１０１の上面は吸熱されながら冷たくなり、下の面は発熱されながら熱くなる。これによって、冷却容器部２００にも冷気が伝達されて冷却空間２５が凍るようになり、また放熱部３００には放熱ファン１０７が回転しながら熱を発散させて熱電素子の効率を定常状態に維持するようにする。
ここで、容器上部２ｒの冷却空間２５に充満された水が凍りながら体積が膨脹すると、弾性チューブ４ｒが収縮され、使用しながら氷が溶けるようになると弾性チューブ４ｒが復元しながら冷却空間２５には常に氷と水と氷が混ざり合った状態に充満されていて容器上面に常に冷気が効率的に伝達され、弾性チューブ４ｒの収縮と復元によって容器上部２ｒの変形や破損を防止することになる。
前記容器上部２ｒに収納部２３ａを形成した構造の冷却容器は、長い間、対話をしながら飲食するような居酒屋などで使用するのに適している。また、ビュッフェ食堂で冷たく食べる飲食を盛って置いてヒンジ結合して回動開閉される蓋が装着された冷却容器を使用すると飲食の味をそのまま維持することができる。

前記第１８実施例による冷却容器１ｒと第１９実施例による冷却容器１ｓは、食卓に一体形として構成して使用することができる。 Hereinafter, various preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A connecting bolt 7 for integrally connecting the plug, a packing 6 and a plug bolt 5 for fastening to the water inlet are added.
The upper portion 2 of the container can be filled with food that makes the taste cooler and cooler on the upper surface, while the water generated by the condensation due to the temperature difference between the upper surface of the cold container and the room air during use is not centered on the food. Groove 23 is formed of circular and radial grooves so that water flows naturally to the periphery at the center, and the current temperature of the upper surface of the container is formed at the center of the upper surface. Is formed. In addition, a coupling protrusion 26 provided with a female screw portion is formed in the central portion on the lower surface of the container upper portion 2, and water is injected into the side surface while communicating with the water inlet 33 of the container lower portion 3. A water injection passage 26a is formed. Here, since the upper surface of the container upper part 2 has a shape in which the central part is raised, when used for the purpose of serving sashimi on the cooling container, the sashimi can be served as it is without needing to lay a thousand pieces on the bottom. Since it can, it can be used hygienically and cold can be effectively transmitted to food.
The temperature display unit 24 eats and eats while watching the temperature, so that the taste of food such as sashimi is further improved psychologically so as to have a visually fresh feeling. As the display method, it is possible to display with an analog thermometer or a digital thermometer, or to use a thermo-color for judging the temperature by using a color change due to a chemical change at a constant temperature.
The container lower part 3 is in the form of a circular box having the same size as the container upper part 2 and serves as a container cradle. The container lower part 3 gradually lowers toward the center part. A hollow projection protrudes upward at a position corresponding to the coupling protrusion 26 of the upper part 2, an upper part of the inner peripheral surface is provided with a female screw, and a male screw of the coupling bolt 7 is fastened. A water inlet 33 having a possible diameter is formed and communicated with the inside.

In particular, when a metal material is used, the surface is finished by a surface treatment method that is harmless to the human body, such as gold plating, silver plating, silver nano-coating, ceramic coating, and anodizing. In addition, when the clad plate is used, the surface layer is thicker than a metal material that has been painted, plated and surface-treated on a metal, so that it is possible to maintain a beautiful state semipermanently. Here, when silver nano-coating is applied to the surface of the container, it will be a mine that kills bacteria present in food such as sashimi.
