2 9 9 1 7 7號公報 [專利文獻6]曰本特開2000-70 5 6號公報 [專利文獻7]日本特開2〇〇〇-4752號公報 200800746 (2) [專利文獻8]日本特開平10-262535號公報 【發明內容】 [發明所欲解決之問題] 本體或蓋構件，一般係藉由樹脂、典型上爲聚丙烯 (PP)所成形。藉由採用聚丙烯作爲材料，可容易實現保冷 箱之輕量化，並可降低保冷箱之材料成本。然而，由樹脂 之成形品，一般係會產生歪曲。因而，在關閉蓋構件之情 ^ 況時，有時會在本體與蓋構件之間產生間隙。 該間隙較小之情況時，由於蓋構件係由樹脂所構成， 因此在關閉蓋構件之際，藉由該蓋構件之彎曲將上述歪曲 相抵，藉此，可將上述保冷室密封。然而，保冷箱，係爲 了實現保存魚之功能，其外形尺寸不得不成爲一定以上之 大小，因此作爲成形品之本體或蓋構件之歪曲有時也會變 得相當大。在如此之情況下，對於藉由蓋之彎曲將上述歪 ^ 曲相抵之事，有時也會有困難。例如，將蓋構件形成長方 形，且將其長邊部分夾介固定具固定於本體之類型者，係 在蓋構件一邊整體地大彈性變化一邊固定於本體之情況下 ，有時蓋構件之短邊部分會從本體浮起來。爲了防止此事 ，亦可在蓋構件之短邊部分設置固定具’但如此的話’蓋 構件之開閉作用則會變得非常麻煩。 不過，上述間隙較小之情況時’係藉由設在蓋構件的 墊圈之變形來塡補該間隙。亦即’將墊圈設置成使其從蓋 構件突出，在關閉該蓋構件時’將墊圈配置成使其被夾入 200800746 (3) 於本體與蓋構件之間，且被壓入於間隙。然而，作爲成形 品之本體或蓋構件之歪曲較大，而在本體與蓋構件之間局 部地產生較大的間隙之情況時，爲了塡補該間隙墊圈係必 須設置成使其從蓋構件較大地突出。如此地，將墊圈設置 成使其從蓋構件一致地較大地突出時，上述間隙之較小的 部位，則會極端地將墊圈按壓變形，其結果，對於釣客來 說將蓋構件關閉之作業則變得困難。更且，對於本體或蓋 ^ 構件之歪曲的程度來說，亦可預料到即使設置墊圏也會在 本體與蓋構件之間殘留間隙。 爲了解決該問題，例如將墊圈藉由發泡樹脂所構成， 且將發泡倍率較大地設定即可。但是，這樣的對策，墊圈 之耐久性會顯著地降低，且藉由重複蓋構件之開閉墊圈有 可能會損傷。又，原本使歪曲變小地將本體及蓋構件成形 即可，但不可能使成形品之歪曲消失。 因此，本發明之目的，係提供一種：不必犧牲蓋構件 φ 之操作性’即可確實地塡補本體與蓋構件之間的間隙而維 持高保冷效果之保冷箱。 [用以解決問題之手段] (1)爲了達成上述目的，本發明之保冷箱，係具備有 :具有設有開口之上面，且劃分有接連於該開口的保冷室 之保冷箱本體；及設在保冷箱本體，且將上述開口開閉之 蓋構件；及介在保冷箱本體之上述上面的開口周緣部與蓋 構件之間，在蓋構件關閉上述開口之狀態將上述保冷室密 200800746 (4) 封之可彈性變形之墊圏；以及爲了將在蓋構件關閉上述開 口之際產生的保冷箱本體的上面與蓋構件之間的距離之偏 差相抵，介在墊圈與保冷箱本體之間或是墊圈與蓋構件之 間，使內部壓力變爲均等地變形自如之內壓均等體。 • 構成保冷箱本體及蓋構件之材料係並非特別限定，但 爲了將該等成本廉價地製造，一般藉由聚丙烯等之樹脂來 成形爲較理想。如此地將保冷箱本體及蓋構件藉由樹脂來 成形時，在作爲成形品之保冷箱本體及蓋構件就會產生歪 ® 曲。該歪曲成爲原因，在蓋構件關閉保冷箱本體的開口之 狀態，保冷箱本體之上面，具體上該上面之開口的周緣部 與蓋構件之間的距離會變化。即，保冷箱本體之開口的周 緣部與蓋構件之間的間隙，就保冷箱本體的上面之周方向 並非一致，存在有該間隙變大之部位及變小之部位。 蓋構件關閉上述開口時，墊圏就會介在蓋構件與保冷 箱本體之間，且抵接於上述開口之周緣部。因此，將保冷 | 箱本體之保冷室密封。如上述地，由於一般保冷箱本體之 開口的周緣部與蓋構件之間的距離並非一定，因此該距離 較小之部位，在蓋構件關閉上述開口時墊圈係相對地較強 地被按壓，又，上述距離較大之部位，在蓋構件關閉上述 開口時墊圏係相對地較弱地被按壓。因此，在蓋構件關閉 上述開口之瞬間，與墊圈相對地較強地被按壓之部位對應 的內壓均等體之部位，該內壓均等體之內壓局部地變大， 又，與墊圈相對地較弱地被按壓之部位對應的內壓均等體 之部位，該內壓均等體之內壓局部地變小。 200800746 (5) 如此的內壓均等體之內部壓力的分布，係使該內部壓 力變成均等地使該內壓均等體立即變形。亦即，內壓均等 體係從內部壓力較高的部位往較低的部位流動。換言之， 不管保冷箱本體之開口的周緣部與蓋構件之間的距離之大 小，爲了將該距離之偏差相抵內壓均等體會流動。此情況 下，若將內壓均等體配置於墊圏與保冷箱本體之間的話， 內壓均等體係會充塡在墊圈與保冷箱本體之間產生的間隙 。又，若將內壓均等體配置於墊圈與蓋構件之間的話，內 ^ 壓均等體係會充塡在墊圈與蓋構件之間產生的間隙。藉此 ，即使保冷箱本體之開口的周緣部與蓋構件之間的距離並 非一定，藉由內壓均等體之變形墊圏係亦可確實地密合於 保冷箱本體及蓋構件之雙方，將上述保冷室確實地密封。 (2)亦可：上述蓋構件，係在關閉上述開口之狀態於 與上述保冷箱本體之上述開口周緣部相對向之部位具備有 開口於該開口周緣部側的形成環狀之周圍溝，上述墊圈， ^ 係以從上述周圍溝之開口突出之狀態配置於該周圍溝內， 並且以可朝該周圍溝的深度方向進退之方式滑動自如地嵌 入於該周圍溝內，而上述內壓均等體，係介在於上述周圍 溝的底面與上述墊圈之間。 此情況下，上述墊圈，係嵌入於設在蓋構件之周圍溝 ，且將上述內壓均等體作爲上述墊圈之座構件配置於上述 周圍溝之深處。即，上述墊圈，係夾介上述內壓均等體嵌 入於上述周圍溝。接著，在蓋構件關閉上述開口之際，從 上述周圍溝突出的墊圈會抵接於保冷箱本體的開口之周緣 200800746 (6) 部，並將上述保冷室密封。如上述地，因爲一般在作爲成 形品之保冷箱本體及蓋構件會產生歪曲，所以上述開Π的 周緣部與上述周圍溝的底面之間的距離係並非一定。該距 離較小之部位中，在關閉蓋構件之瞬間墊圈係相對地較強 地被按壓，又，上述距離較大之部位中，在關閉蓋構件之 瞬間墊圈係相對地較弱地被按壓。因此，在關閉蓋構件之 瞬間，與墊圏相對地較強地被按壓之部位對應的內壓均等 體之部位中，該內壓均等體之內壓係局部地變大，又，與 ^ 墊圈相對地較弱地被按壓之部位對應的內壓均等體之部位 中，該內壓均等體之內壓係局部地變小。 如上述地，如此的內壓均等體之內部壓力的分布，係 使該內部壓力變成均等地使該內壓均等體立即變形。亦即 ，內壓均等體係從內部壓力較高的部位往較低的部位流動 。換言之，不管上述開口的周緣部與上述周圍溝的底面之 間的距離之大小，內壓均等體係於墊圈與上述周圍溝的底 $ 面之間隙流動且充塡。藉此，即使上述開口的周緣部與上 述周圍溝的底面之距離並非一定，藉由內壓均等體之變形 墊圏與上述開口的周緣部之間的距離也會變爲一定，因此 ，墊圈係可確實地而且一致地按壓於上述開口之周緣部。 (3)上述內壓均等體，係具備有：液體或凝膠狀之芯 部；及將該芯部收容，並且沿著上述周圍溝之長邊方向配 置的具有可撓性之管狀袋，而構成。 芯部，係可採用例如凝膠狀之聚胺甲酸酯等。凝膠狀 之物質，係具有一定的流動性，因此作爲構成芯部之材料 200800746 (7) 爲較理想。但是，亦可採用流動性更優異之物質，典型上 爲滑脂等，來作爲構成芯部之材料，或者亦可採用極富有 流動性之油或水，來作爲構成芯部之材料。又，藉由將芯 部收容於具有可撓性之管狀袋，芯部在管狀袋內可極迅速 地流動。 (4) 上述墊圈，係實心構件爲較理想。 由於墊圈具有實心構造’在關閉蓋構件之際可防止墊 圈之橫彎等之局部的變形，而墊圈會穩定地抵接於上述開 ® 口之周緣部。 (5) 上述管狀袋，係亦可由富有延伸性之薄管來構成 〇 該結構中，芯部係可朝所有方向輕易地流動。因此， 墊圈與上述開口之周緣部更加穩定地而且均等地抵接。 (6) 又，亦可：在上述保冷箱本體之上面的開口之周 緣部，設有開口於該上面的形成環狀之周圍溝，而上述墊 A 圈，係以從上述周圍溝之開口突出之狀態配置於該周圍溝 內，並且以可朝該周圍溝的深度方向進退之方式滑動自如 地嵌入於該周圍溝內，而上述內壓均等體，係介在於上述 周圍溝的底面與上述墊圈之間。 在此情況下，上述墊圈，係嵌入於設在保冷箱本體之 周圍溝，且將上述內壓均等體作爲上述墊圈之座構件配置 於上述周圍溝之深處。即，上述墊圈，係夾介上述內壓均 等體嵌入於上述周圍溝。接著，在蓋構件關閉保冷室的開 口之際，從上述周圍溝突出的墊圈會抵接於該開口之周緣 -10- 200800746 (8) 部，並將上述保冷室密封。如上述地，因爲一般在作爲成 形品之保冷箱本體及蓋構件會產生歪曲，所以蓋構件與上 述周圍溝的底面之間的距離係並非一定。該距離較小之部 位中，在關閉蓋構件之瞬間墊圈係相對地較強地被按壓， 又，上述距離較大之部位中，在關閉蓋構件之瞬間墊圈係 相對地較弱地被按壓。因此，在關閉蓋構件之瞬間，與墊 圏相對地較強地被按壓之部位對應的內壓均等體之部位中 ，該內壓均等體之內壓係局部地變大，又，與墊圈相對地 較弱地被按壓之部位對應的內壓均等體之部位中，該內壓 均等體之內壓係局部地變小。 如上述地，如此的內壓均等體之內部壓力的分布，係 使該內部壓力變成均等地使該內壓均等體立即變形。亦即 ，內壓均等體係從內部壓力較高的部位往較低的部位流動 。換言之，不管蓋構件與上述周圍溝的底面之距離之大小 ，內壓均等體係於墊圈與上述周圍溝的底面之間隙流動且 充塡。藉此，即使蓋構件與上述周圍溝的底面之距離並非 一定，藉由內壓均等體之變形墊圈與蓋構件之間的距離也 會變爲一定，因此，墊圈係可確實地而且一致地按壓於蓋 構件。 (7)上述內壓均等體，係具備有：液體或凝膠狀之芯 部；及將該芯部收容，並且沿著上述周圍溝之長邊方向配 置的具有可撓性之管狀袋，而構成。 芯部，係可採用例如凝膠狀之聚胺甲酸酯等。凝膠狀 之物質，係具有一定的流動性，因此作爲構成芯部之材料 -11 - 200800746 Ο) 爲較理想。但是，亦可採用流動性更優異之物質，典型上 爲滑脂等，來作爲構成芯部之材料，或者亦可採用極富有 流動性之油或水，來作爲構成芯部之材料。又，藉由將芯 部收容於具有可撓性之管狀袋，芯部在管狀袋內可極迅速 地流動。 (8) 上述墊圈，係實心構件爲較理想。 由於墊圈具有實心構造，在關閉蓋構件之際可防止墊 圈之橫彎等之局部的變形，而墊圈會穩定地抵接於上述開 ¥ 口之周緣部。 (9) 上述管狀袋，係亦可由富有延伸性之薄管來構成 〇 該結構中，芯部係可朝所有方向輕易地流動。因此， 墊圏與上述開口之周緣部更加穩定地而且均等地抵接。 [發明之效果] | 根據本發明，藉由內壓均等體流動變形，即使蓋構件 與保冷箱本體之間的距離並非一定，在關閉蓋構件之際介 在於蓋構件與保冷箱本體之間的墊圈也會以均等的壓力抵 接於兩者。因此，即使是在作爲樹脂成形品之保冷箱本體 及蓋構件產生歪曲之情況，內壓均等體也會流動變形使該 歪曲相抵。其結果，只將蓋構件關閉即可簡單且確實地密 封保冷箱本體之保冷室。 【實施方式】 -12- 200800746 (10) [發明之實施形態] 以下，一面參照適當圖面，一面根據理想之實施形態 詳細地說明本發明。第1圖，係本發明之一實施形態的保 冷箱之外觀立體圖。第2圖，係該保冷箱之要部放大立體 圖。保冷箱1 0，係使用在釣魚等之休閒，且可冷藏釣到的 魚或飮料水等。保冷箱1 〇，係具備有：本體11 (保冷箱本 體）；及開閉自如地設在本體11之蓋構件12 ;以及設在本 體1 1之把手1 3。第1圖係圖示關閉蓋構件1 2之狀態，第2圖 ® 係顯示打開蓋構件1 2之狀態。上述把手1 3，係可轉動地設 在本體11，可在如第1圖所示地朝上方立起的姿勢、與如 第2圖所示地倒伏的姿勢之間進行變化。釣客係藉由使把 手1 3立起，可將其把持而帶著走，又，將保冷箱載置於海 岸等時，可使把手1 3倒伏。 本體1 1，係由樹脂（典型上爲聚丙烯）所成形，且如該 圖所示地，形成大致直方體形狀。在本體1 1之內部，形成 $ 有保冷室14。該保冷室14，係如第2圖所示地接連於本體 1 1之上面15，且於該上面15形成開口 16。該開口 16之周緣 部17係形成滑面。如後述地，將蓋構件12關閉時，設在該 蓋構件12之墊圈18會抵接於上述周緣部17，藉此，蓋構件 12則氣密地與本體1 1接觸。又，在劃分保冷室14的壁19( 本體1 1之側壁及底壁）之內部，裝入有隔熱材。該隔熱材 ，係採用典型上爲發泡聚胺甲酸酯、發泡塑料等發泡樹脂 。但，亦可施加於發泡樹脂而配置真空隔熱板。 在本體1 1的上端部之前側邊部及後側邊部，分別設有 -13- 200800746 (11) 凹部20、21。凹部20，係朝上述前側邊部之長邊方向延伸 ，且朝本體1 1之厚度方向凹陷。接著，在該凹部20設有撐 桿22。該撐桿22，係如後述地使蓋構件12被卡合，且在關 閉蓋構件1 2時，將該蓋構件1 2確實地保持於關閉狀態。又 ，凹部21，係與凹部20同樣之形狀，且在該凹部21配置有 與上述撐桿22同樣之撐桿。藉由在本體11的上端部之前側 邊部及後側邊部分別設置撐桿22，則蓋構件12不管從前側 或後側均可開閉。不過，當然亦可將上述撐桿22設在本體 1 1的前側或後側之其中任何一方，而將蓋構件1 2構成使只 能從前側或後側之其中任何一方開閉。 第3圖，係第1圖之m - ΠΙ剖面圖。 如第1圖及第3圖所示，蓋構件12係對應本體1 1的上面 1 5之外形形狀而形成矩形之板狀。蓋構件1 2，係具備有： 外框23、以及嵌入於外框23之內蓋24。外框23及內蓋24， 係與本體11同樣地，由樹脂（典型上爲聚丙烯）所成形。 如第2圖及第3圖所示，外框23係具備有：卡合爪26及 把扣25。卡合爪26，係分別設在外框23的前側之緣部及後 側之緣部，且各卡合爪26，係配置在當關閉蓋構件1 2時與 本體1 1之撐桿22相對應之位置。因此，將蓋構件12關閉時 ，卡合爪26則會卡合於撐桿22，且保持蓋構件12之關閉狀 態。又，上述把扣2 5，係沿著外框2 3的前側之緣部及後側 之緣部分別被設置，可解除各卡合爪26與撐桿22之卡合。 即，在關閉蓋構件12之狀態操作把扣25時，各卡合爪26就 會從撐桿22背離，且解除兩者之卡合，藉此，蓋構件12係 200800746 (12) 可輕易地變化成第2圖所示之姿勢。又，由於上述卡合爪 26及把扣25以及上述撐桿22之結構係爲已知’因此省略此 等之詳細的說明。 如第3圖所示，內蓋24係嵌入於外框23之內側。內蓋 24，係例如可藉由螺栓固結於外框23。在內蓋24之內部裝 入隔熱材。該隔熱材’係採用例如發泡聚I女甲酸醋、發泡 塑料等發泡樹脂。但，亦可施加於發泡樹脂而配置真空隔 熱板。在內蓋24的內面2 8之周圍形成有環狀之溝槽27(周 ® 圍溝槽）。該溝槽27，係在關閉蓋構件12時，設置在與本 體1 1的開口 1 6之周緣部1 7相對向之位置。如第3圖所示， 該溝槽27，係開口於內蓋24之內面28，即上述周緣部17側 〇 第4圖，係保冷箱1 0之要部放大剖面圖，詳細地顯示 本體11及蓋構件12之構造。 如第3圖异第4圖所示，在上述溝槽27嵌入有墊圈18, ^ 且在該墊圈18與溝槽27的底面29之間配設有間隙充塡材 3 0(內壓均等體）。將蓋構件12關閉時，該內蓋24就會與本 體1 1之上面1 5相對向，且將墊圈1 8按壓於上述開口 1 6之周 緣部1 7。藉此，將上述開口 1 6閉塞，且將保冷室1 4密封。 第5圖，係第4圖之V-箭視圖，詳細地顯示間隙充塡 材3 0及墊圈18之構造。 墊圈1 8，係剖面形狀爲矩形，且整體上形成帶狀。本 實施形態中，墊圈18係由彈性體（典型上爲，發泡矽橡膠 、乙烯丙烯三共聚物（EPDM)等）所構成。墊圈18，係具有 -15- 200800746 (13) 實心構造。關於墊圈1 8具備實心構造之作用效果係後述， 但墊圏18，係亦可具備中空構造。 墊圈18之高度尺寸H，係設定爲與溝槽27的深度相對 應之尺寸。總之，墊圈18之高度尺寸Η，係設定成：在將 墊圈18嵌入溝槽27之狀態，使墊圈18之上端部從溝槽27之 開口 31僅突出數毫米。又，墊圈18，係在嵌入溝槽27之狀 態，在第5圖中可朝上下方向滑動。因此，墊圈1 8，係藉 由在第5圖中朝上方被按壓，可退避到溝槽27內。再者， ^ 墊圏18，係亦可形成細長帶狀，沿著上述溝槽27之長邊方 向嵌入，或者亦可形成無端環狀，嵌入於上述溝槽27。 間隙充塡材30，係具備有芯部32及袋（管狀袋）33。間 隙充塡材30，係形成細長帶狀。如上述地，間隙充塡材30 ，係在第5圖中配置於墊圈18之上，且以塡補上述溝槽27 的底面29與墊圏18之間的間隙之方式配置。間隙充塡材30 之長度尺寸，係與溝槽27之長邊方向尺寸對應，且間隙充 0 塡材30，係沿著上述溝槽27之長邊方向嵌入於該溝槽27。 因此，在將間隙充塡材30嵌入於溝槽27之狀態，間隙充塡 材3 0之兩端部，係在溝槽27內相互地相對向且抵接。不過 ，亦可將間隙充塡材30形成無端環狀，嵌入於上述溝槽27 〇 芯部3 2，在本實施形態中係採用凝膠狀之聚胺甲酸酯 。不過，構成芯部32之材料係並非限定於此，可採用滑脂 、油、水等的具有流動性之物質。又，作爲構成芯部32之 材料亦可採用黏液等之黏狀物質。總之，芯部32係可採用 -16- 200800746 (14) 具有一定的流動性及黏性之非壓縮性的凝膠、液體或黏液 。又，袋33，係由具備可撓性之材料所構成，且形成管狀 。上述芯部32，係收容於該袋33。本實施形態中，袋33係 由胺甲酸酯薄片所構成。構成袋33的胺甲酸酯薄片之厚度 尺寸，係在本實施形態中設定爲3 5 μιη，但該厚度尺寸， 係可設定爲5μιη〜50 μιη程度。如此地，藉由將芯部32收 容於具有可撓性之袋33，芯部32係可朝所有方向流動。換 言之，間隙充塡材30，係使凝膠狀之芯部3 2整體成均等的 ®壓力地流動且變形。 本實施形態之保冷箱1 〇，係如第1圖及第2圖所示，蓋 構件1 2對於本體1 1進行開閉。釣客，係藉由操作蓋構件1 2 之把扣25，可將蓋構件12打開，且藉由使蓋構件12倒伏， 蓋構件12之卡合爪26會卡合於撐桿22，且確實地關閉蓋構 件12。又，由於本體1 1及蓋構件12係由聚丙烯等之樹脂所 構成，因此具有將該等構成成本廉價之優點。但是，由於 $ 本體1 1及蓋構件1 2係由聚丙烯等之樹脂所成形，對於作爲 產品之本體1 1及蓋構件1 2會產生歪曲。 例如在蓋構件12產生歪曲時，如第4圖所示地溝槽27 之底面29就會彎曲。因而，在將蓋構件12對於本體1 1關閉 之狀態，本體11之開口 16的周緣部17與蓋構件12之溝槽27 的底面29之間的距離S1會變化。即，該距離S1就溝槽27 之長邊方向並非一致，上述開口 16的周緣部17與溝槽27的 底面29之間的距離S 1會因溝槽27之部位而不同。該情況 時，假定並無設置上述間隙充塡材30的話，在將墊圈18嵌 -17· 200800746 (15) 入於溝槽27之狀態，該墊圈18從溝槽27突出之高度就會變 化。即，墊圏18之從溝槽27鼓出之尺寸會因溝槽27之部位 而不同。因而，將蓋構件1 2關閉之際，在墊圈1 8從溝槽2 7 較大地突出之部位，會將該墊圏1 8較強地按壓於上述周緣 部17，另一方面，在墊圈18從溝槽27較小地突出之部位， 會將該墊圈18較弱地按壓於上述周緣部17。在將墊圈18較 弱地按壓於上述周緣部17之部位，係有無法保持蓋構件12 與本體1 1的氣密性之可能性。又，在將墊圈18較強地按壓 ^ 於上述周緣部17之部位產生之情況，有可能將蓋構件12關 閉於本體11之作業會變得困難。 可是，本實施形態之保冷箱1 〇中，因爲設有上述間隙 充塡材3 0，所以在將上述蓋構件1 2關閉之際，上述距離 S 1較小之部位，則瞬間地間隙充塡材3 0相對地變得高壓， 又，上述距離S 1較大之部位，則瞬間地間隙充塡材3 0相 對地變得低壓。即，在間隙充塡材30之內部會產生內壓局 ^ 部地變大之部位與局部地變小之部位。 如此地藉由間隙充塡材30之內壓進行變化，該間隙充 塡材30，係使其內部壓力成均等地變形。亦即，間隙充塡 材3 0，係從內部壓力較高之部位往較低之部位流動，且不 管上述距離S1之大小，間隙充塡材30，係於墊圈18與上 述溝槽27的底面29之間隙流動且充塡。藉此，即使上述距 離S 1並非一定，藉由間隙充塡材3 0之變形墊圈1 8與上述 開口 16的周緣部17之間的距離S2也會變爲一定，因此， 墊圏18係可確實地而且一致地按壓於上述開口 16之周緣部 -18- 200800746 (16) 1 7。其結果，本體1 1，係藉由蓋構件i 2確實地被密閉，而 且，由於上述距離S2變爲一定，開閉蓋構件12之作業則 變得容易。 又，本實施形態中，上述間隙充塡材3 0，係由液體或 凝膠狀之芯部32、及收容該芯部32之袋3 3所構成，因此在 關閉蓋構件12之瞬間芯部32可極迅速地流動於袋33內。藉 此，間隙充塡材3 0，係可瞬時地充塡上述墊圈丨8與上述溝 槽27的底面29之間隙。 ® 更且，本實施形態中，因爲上述墊圈18具有實心構造 ，所以在關閉蓋構件12之際可防止墊圈18之橫彎等之局部 的變形。因此，墊圈18係穩定地抵接於上述開口 16之周緣 部17，藉由蓋構件12可確實地密閉本體u。 加上，本實施形態中，上述間隙充塡材30之袋33，係 厚度薄的聚胺甲酸酯管所構成，富有可撓性。因此，上述 芯部3 2，係可朝所有方向輕易地流動，藉此，具有··墊圈 $ 18與上述開口 16之周緣部17更加穩定地且均等地抵接之優 點。 本實施形態中，上述間隙充塡材30，係藉由將呈非壓 縮性之芯部32裝入於具備有可撓性之袋33所構成。因此， 在該間隙充塡材30之製造中，裝入袋33之芯部32的量（體 積）爲重要的管理項目，藉由芯部32之重量可正確地把握 芯部3 2之體積。亦即，即使是富有流動性之芯部3 2，其體 積之管理簡單，且也有可降低間隙充塡材30的製造成本之 優點。 -19- 200800746 (17) 再者，構成上述袋3 3之材料，係並非限定於胺甲酸酯 薄片，例如可採用合成橡膠。合成橡膠之種類係並非特別 限定，但亦可爲富有延伸性之物。構成袋33之合成橡膠富 有延伸性之情況時，藉由將芯部32收容於該袋33，芯部32 係可朝所有方向更加順利地流動。換言之，袋3 3不管長邊 方向或與長邊方向垂直交叉之方向，均可輕易地變形，其 結果，使凝膠狀之芯部3 2整體成均等的壓力地流動變形。 如此地在袋3 3由富有延伸性之材料所構成之情況，間 隙充塡材30之長度尺寸，係亦可設定比溝槽27之長度方向 尺寸更短一些。如上述地，在關閉蓋構件1 2之際，藉由間 隙充塡材3 0之內壓進行變化，該間隙充塡材30係使其內部 壓力成均等地變形。亦即，間隙充塡材3 0，係從內部壓力 較高之部位往較低之部位流動，且不管上述距離S 1 (參照 第4圖）之大小，間隙充塡材30係於墊圈18與上述溝槽27的 底面29之間隙流動且充塡。此時，因爲袋33富有延伸性， 所以間隙充塡材3 〇係朝長邊方向延伸，且在兩端彼此密合 後，朝與該長邊方向垂直交叉之方向，即朝高度方向變形 。藉此，即使上述距離S 1並非一定，藉由間隙充塡材3 0 之變形，墊圈1 8與上述開口 1 6的周緣部1 7之間的距離S2 也會變成一定，因此，墊圈18係可確實地而且一致地按壓 於上述開口 1 6之周緣部1 7。 其次，說明關於本實施形態之變形例。 第6圖，係本實施形態之變形例的保冷箱之要部放大 剖面圖。 -20- 200800746 (18) 本變形例的保冷箱40與上述實施形態的保冷箱10不同 之處爲··上述保冷箱1 0 ’係於蓋構件1 2設置溝槽2 7，且於 該溝槽27嵌入間隙充塡材3〇及墊圈1 8，相對於此，本變形 例之保冷箱4 0，係於本體1 1側設置溝槽2 7 ’且於該溝槽2 7 嵌入間隙充塡材3 0及墊圈1 8，這一點。再者’關於保冷箱 4 0之其他的結構，係與上述保冷箱1〇同樣。 如該圖所示，在該保冷箱40中，也是於本體11之上面 15設有開口 16。接著，接連於該開口 16而形成保冷室14。 ^ 上述溝槽27，係設在上述開口 16之周緣部17。該溝槽27， 係藉由以開口於上述上面1 5之方式朝下方切入所構成，且 沿著上述周緣部17形成環狀。在該溝槽27之深處部嵌入有 間隙充塡材30，更且，在該間隙充塡材30之上配置有墊圈 1 8。墊圈1 8，係如該圖所示地從上述上面1 5僅突出數毫米 ，且藉由關閉蓋構件12，墊圏18會抵接於蓋構件12之內面 42 〇 ^ 在本變形例中，因爲也設有間隙充塡材30，所以在將 蓋構件12關閉之際，上述溝槽27的底面29與蓋構件12的內 面42之間的距離S1較小之部位，則瞬間地間隙充塡材30 相對地變得高壓，又，上述距離S 1較大之部位，則瞬間 地間隙充塡材30相對地變得低壓。即，在間隙充塡材30之 內部會產生內壓局部地變大之部位與局部地變小之部位。 間隙充塡材3 0之內壓變化時，如上述地，該間隙充塡 材3 0係使其內部壓力成均等地變形。亦即，間隙充塡材3 0 ’係從內部壓力較高之部位往較低之部位流動，且不管上 -21 - 200800746 (19) 述距離S 1之大小，間隙充塡材3 0係於墊圈1 8與上述溝槽 27的底面29之間隙流動且充塡。藉此，即使上述距離S1 並非一定，藉由間隙充塡材30之變形，墊圈18與蓋構件12 的內面42之間的距離S2也會變成一定，因此，墊圈18係 可確實地而且一致地按壓於該蓋構件1 2之內面42。其結果 ，本體1 1，係藉由蓋構件1 2確實地被密閉，而且，由於上 述距離S2變爲一定，開閉蓋構件12之作業則變得容易。 $ 其次，說明關於本實施形態之其他的變形例。 第7圖，係本實施形態之其他的變形例的墊圈之放大 剖面圖。 本變形例的墊圈45與上述實施形態的墊圈18不同之處 爲：墊圈45係具備有中空構造，且於內部密封有上述芯部 32，這一點。構成墊圏45之材料，係由發泡矽橡膠、乙烯 丙烯三共聚物（EPDM)等之彈性體所構成。又，構成芯部 3 2之材料，係如上述地可採用凝膠狀之聚胺甲酸酯。不過 φ ，構成芯部32之材料係並非限定於此，亦可採用滑脂、油 、水等的具有流動性之物質、黏液等之黏狀物質。總之， 芯部32係可採用具有一定的流動性及黏性之非壓縮性的凝 膠、液體或黏液。 如第7圖所示，墊圈4 5係具備有：一對側壁部4 6、4 7 、及厚底部48、以及頂板部49，且在藉由該等所劃分的空 間50收容有芯部32。側壁部46、47，係比其他之部分較爲 薄。由於芯部係如上述地具備有流動性，因此可藉由注射 器等注入至墊圏45內。具體上，將注射器的針頭插入厚底 -22- 200800746 (20) 部4 8，並將芯部3 2注入至上述空間5 0。此時，例如藉由其 他的注射器，將在空間50內預先存在的空氣排出爲較理想 。該墊圈45，係如上述實施形態及變形例地嵌入於本體1 1 或蓋構件1 2，但此時，係將厚底部48側插入於設在本體1 1 或蓋構件1 2之溝槽2 7。 本變形例，係將芯部32收容於墊圈45內，因此在保冷 箱10、40之組裝中，只將單一的構件（即該墊圈45)裝入本 體11或蓋構件12即可，故組裝作業變得容易。而且，不需 要收容芯部32之袋33，因此亦可削減零件數量。又，將墊 圏45之側壁部46、47形成比厚底部48和頂板部49較爲薄， 因此墊圏45容易彎曲，芯部32可迅速地流動於空間50內。 [產業上之可利用性] 本發明，係可適用於在釣魚等之休閒所使用的保冷箱 【圖式簡單說明】 第1圖，係本發明之一實施形態的保冷箱之外觀立體 圖。 第2圖，係本發明之一實施形態的保冷箱之要部放大 立體圖。 第3圖，係第1圖之瓜-瓜剖面圖。 第4圖，係本發明之一實施形態的保冷箱之要部放大 剖面圖。 -23- 200800746 (21) 第5圖，係第4圖之 第6圖，係本發明 要部放大剖面圖。 第7圖，係本發明 圈之放大剖面圖。 V-箭視圖。 L 一實施形態之變形例的保冷箱之 L 一實施形態之其他的變形例的墊200800746 (1) IX. [Technical Field] The present invention, It is about the structure of the cold box used for leisure such as fishing. [Prior Art] For example, a fisherman, It carries a cold storage box while fishing. Cold paint, Owner Φ A container for the purpose of keeping the caught fish cold. therefore, Since the previous cooling equipment system was required to have high cooling capacity. In order to improve the cooling capacity of the cold box, Since the past, various improvements have been applied (for example, Reference Patent Document 1 to Patent Document 8) 保 In the cold storage box disclosed in Patent Document 1, The cover member is opened and closed freely. Also, the body is formed in the cold-keeping chamber. The cooling chamber is sealed by closing the lid member, and the fish or the like housed in the cold storage chamber is stored. In order to reliably seal the cold room, a gasket is placed under the cover member. that is, When the cover member is closed, the gap between the cover member and the body is compensated by the gasket ,, The cold room is sealed. [Patent Document 1] JP-A-2002-145357 (Patent Document 3) JP-A-2002-145357 (Patent Document 4) Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei.

By using polypropylene as a material, It is easy to realize the weight reduction of the cold storage box. And can reduce the material cost of the cold box. however, a molded article made of a resin, Generally, there will be distortions. thus, When closing the cover member, Sometimes a gap is created between the body and the cover member. When the gap is small, Since the cover member is made of resin, Therefore, when the cover member is closed, The above distortion is offset by the bending of the cover member, With this, The above cold storage chamber can be sealed. however, Cold box, In order to realize the function of saving fish, Its external dimensions have to be more than a certain size. Therefore, the distortion of the body or the cover member as a molded article sometimes becomes quite large. In such a case, For the above-mentioned 曲 ^ 曲 藉 藉 藉 盖 盖 盖 盖 Sometimes there are difficulties. E.g, Forming the cover member into a rectangular shape, And the long side portion of the fixture is fixed to the type of the body, In the case where the cover member is fixed to the main body while being elastically changed as a whole, Sometimes the short side of the cover member floats from the body. In order to prevent this, It is also possible to provide the fixing member 'on the short side portion of the cover member. However, the opening and closing action of the cover member becomes very troublesome. but, When the gap is small, the gap is compensated by deformation of the gasket provided in the cover member. That is, 'the gasket is arranged such that it protrudes from the cover member, When the cover member is closed, the gasket is configured such that it is sandwiched between 200800746 (3) between the body and the cover member, And is pressed into the gap. however, The distortion of the body or cover member as a molded article is large. When a large gap is locally generated between the body and the cover member, In order to compensate for the gap, the gasket system must be arranged to protrude largely from the cover member. So, When the gasket is disposed such that it protrudes uniformly from the cover member, The smaller part of the above gap, Will deform the gasket extremely, the result, It is difficult for the fisherman to close the cover member. And, For the degree of distortion of the body or cover member, It is also expected that a gap will remain between the body and the cover member even if the pad is provided. In order to solve this problem, For example, the gasket is composed of a foamed resin. Further, the expansion ratio may be set to be large. but, Such a countermeasure, The durability of the gasket is significantly reduced, Moreover, it may be damaged by repeating the opening and closing gasket of the cover member. also, Originally, the body and the cover member can be formed by making the distortion small. However, it is impossible to make the distortion of the molded article disappear. therefore, The purpose of the present invention, Provide a type: It is possible to surely fill the gap between the body and the cover member without sacrificing the operability of the cover member φ to maintain the cold insulation effect of the high cooling effect. [Means to solve the problem] (1) In order to achieve the above objectives, The cold box of the present invention, The system has: Having an opening above, And dividing the cold storage box body of the cold preservation chamber connected to the opening; And located in the body of the cold box, And a cover member that opens and closes the opening; And between the peripheral edge portion of the opening above the cover body and the cover member, The elastically deformable pad which is sealed by the above-mentioned cold storage chamber in the state of closing the opening of the cover member 200800746 (4); And in order to offset the deviation of the distance between the upper surface of the cold-insulation box body and the cover member which is generated when the cover member closes the opening, Between the gasket and the body of the cold box or between the gasket and the cover member, The internal pressure is made to be equal to the internal pressure equalization body. • The material constituting the cold box body and the cover member is not particularly limited. But in order to make these costs cheap, It is generally preferred to form by a resin such as polypropylene. When the cold box body and the cover member are formed of resin as described above, 歪 ® 曲 is produced in the cold box body and the cover member which are molded articles. The distortion is the cause, In a state where the cover member closes the opening of the cold-insulation box body, Above the body of the cold box, Specifically, the distance between the peripheral portion of the upper opening and the cover member changes. which is, a gap between the peripheral portion of the opening of the cold-insulation box body and the cover member, The circumferential direction of the upper surface of the cold box body is not uniform. There is a portion where the gap becomes large and a portion where the gap becomes small. When the cover member closes the opening, The pad is placed between the cover member and the cold box body. And abutting on the peripheral portion of the opening. therefore, Seal the cold insulation chamber of the cold insulation | box body. As mentioned above, Since the distance between the peripheral portion of the opening of the general cold box body and the cover member is not constant, Therefore, the part with a smaller distance, The gasket is relatively strongly pressed when the cover member closes the opening, also, Where the above distance is large, The mat is relatively weakly pressed when the cover member closes the opening. therefore, At the moment when the cover member closes the opening, a portion of the internal pressure equalizer corresponding to the portion strongly pressed against the gasket, The internal pressure of the internal pressure equalizer is locally increased, also, a portion of the internal pressure equalizer corresponding to the portion that is relatively weakly pressed against the gasket, The internal pressure of the internal pressure equalizer is locally reduced. 200800746 (5) The distribution of the internal pressure of such an internal pressure equalizer, This internal pressure is made uniform to immediately deform the internal pressure uniform. that is, The internal pressure is equal to the system flowing from the higher internal pressure to the lower part. In other words, Regardless of the distance between the peripheral portion of the opening of the cold-insulation box body and the cover member, In order to offset the deviation of the distance, the internal pressure equals the flow. In this case, If the internal pressure equalizer is disposed between the mat and the cold box body, The internal pressure equalization system will fill the gap created between the gasket and the body of the cold box. also, If the internal pressure equalizer is disposed between the gasket and the cover member, The internal pressure equalization system will fill the gap created between the gasket and the cover member. Take this Even if the distance between the peripheral portion of the opening of the cold-insulation box body and the cover member is not constant, The deformation pad of the internal pressure equalizer can also be firmly adhered to both the cold box body and the cover member. The cold insulation chamber is reliably sealed. (2) can also: The above cover member, In a state in which the opening is closed, a portion forming a ring-shaped peripheral groove opening on a side of the peripheral edge portion of the opening is provided at a portion facing the peripheral edge portion of the opening of the cooling box main body. The above washer, ^ is disposed in the surrounding groove in a state protruding from the opening of the surrounding groove, And slidably embedded in the surrounding groove so as to advance and retreat in the depth direction of the surrounding groove. And the above internal pressure equalizer, It is between the bottom surface of the surrounding groove and the gasket. In this case, The above washer, Embedded in a groove provided around the cover member, Further, the internal pressure equalizer is disposed as a seat member of the gasket at a depth of the surrounding groove. which is, The above washer, The internal pressure equalizer is embedded in the surrounding groove. then, When the cover member closes the opening, The gasket protruding from the surrounding groove will abut against the periphery of the opening of the cold box body 200800746 (6), And seal the above cold room. As mentioned above, Because it is generally caused to be distorted by the cold box body and the cover member as a shaped product, Therefore, the distance between the peripheral portion of the opening and the bottom surface of the surrounding groove is not constant. In the smaller part, The gasket is relatively strongly pressed at the moment the cover member is closed, also, Among the above-mentioned areas with large distances, The gasket is relatively weakly pressed at the moment the cover member is closed. therefore, At the moment when the cover member is closed, Among the parts of the internal pressure equalizer corresponding to the portion where the mat is relatively strongly pressed, The internal pressure of the internal pressure equalizer is locally enlarged. also, In the portion of the internal pressure equalizer corresponding to the portion where the washer is relatively weakly pressed, The internal pressure of the internal pressure equalizer is locally small. As mentioned above, The distribution of the internal pressure of such an internal pressure equalizer, This internal pressure is made uniform to immediately deform the internal pressure uniform. That is, The internal pressure equalization system flows from a portion with a higher internal pressure to a lower portion. In other words, Regardless of the distance between the peripheral portion of the opening and the bottom surface of the surrounding groove, The internal pressure equalization system flows and fills the gap between the gasket and the bottom surface of the surrounding groove. With this, Even if the distance between the peripheral edge portion of the opening and the bottom surface of the peripheral groove is not constant, The distance between the spacer and the peripheral portion of the opening is also constant by the deformation of the internal pressure equalizer. Therefore, The gasket is reliably and uniformly pressed against the peripheral portion of the opening. (3) The above internal pressure equalizer, The system has: Liquid or gel-like core; And housing the core, And a flexible tubular bag disposed along the longitudinal direction of the surrounding groove, And constitute. Core, For example, a gelatinous polyurethane or the like can be used. Gelatinous substance, Has a certain degree of fluidity, Therefore, it is preferable as the material constituting the core portion 200800746 (7). but, It is also possible to use substances with better fluidity. Typically, it is a grease, etc. As a material that constitutes the core, Or you can use very fluid oil or water. Comes as a material that constitutes the core. also, By housing the core in a flexible tubular bag, The core flows extremely quickly within the tubular bag. (4) The above washers, Solid components are ideal. Since the gasket has a solid structure, it can prevent partial deformation such as lateral bending of the gasket when the cover member is closed, The gasket will stably abut against the peripheral portion of the above opening. (5) The above tubular bag, The system can also be constructed of thin tubes with extensions. The core system can easily flow in all directions. therefore, The gasket abuts the peripheral portion of the opening more stably and uniformly. (6) Again, Also available: a peripheral portion of the opening above the cold box body, An annular groove is formed on the upper surface of the ring, And the above pad A circle, Disposed in the surrounding groove in a state protruding from the opening of the surrounding groove, And slidably inserted into the surrounding groove so as to advance and retreat in the depth direction of the surrounding groove. And the above internal pressure equalizer, It is between the bottom surface of the surrounding groove and the gasket. In this situation, The above washer, It is embedded in the surrounding groove provided in the body of the cold box. Further, the internal pressure equalizer is disposed as a seat member of the gasket at a depth of the surrounding groove. which is, The above washer, The internal pressure equalizer is embedded in the surrounding groove. then, When the cover member closes the opening of the cold room, A gasket protruding from the surrounding groove will abut against the periphery of the opening -10- 200800746 (8), And seal the above cold room. As mentioned above, Because it is generally caused to be distorted by the cold box body and the cover member as a shaped product, Therefore, the distance between the cover member and the bottom surface of the peripheral groove is not constant. Among the smaller distances, The gasket is relatively strongly pressed at the moment the cover member is closed, also, Among the above-mentioned areas with large distances, The gasket is relatively weakly pressed at the moment the cover member is closed. therefore, At the moment of closing the cover member, In the portion of the internal pressure equalizer corresponding to the portion where the pad is relatively strongly pressed, The internal pressure of the internal pressure equalizer is locally enlarged. also, In the portion of the internal pressure equalizer corresponding to the portion where the gasket is relatively weakly pressed, The internal pressure of the internal pressure equalizer is locally small. As mentioned above, The distribution of the internal pressure of such an internal pressure equalizer, This internal pressure is made uniform to immediately deform the internal pressure uniform. That is, The internal pressure equalization system flows from a portion with a higher internal pressure to a lower portion. In other words, Regardless of the distance between the cover member and the bottom surface of the surrounding groove, The internal pressure equalization system flows and fills the gap between the gasket and the bottom surface of the surrounding groove. With this, Even if the distance between the cover member and the bottom surface of the surrounding groove is not constant, The distance between the deformation washer and the cover member by the internal pressure equalizer also becomes constant. therefore, The gasket is pressed against the cover member in a sure and consistent manner. (7) The above internal pressure equalizer, The system has: Liquid or gel-like core; And housing the core, And a flexible tubular bag disposed along the longitudinal direction of the surrounding groove, And constitute. Core, For example, a gelatinous polyurethane or the like can be used. Gelatinous substance, Has a certain degree of fluidity, Therefore, it is preferable as the material constituting the core -11 - 200800746 Ο). but, It is also possible to use substances with better fluidity. Typically, it is a grease, etc. As a material that constitutes the core, Or you can use very fluid oil or water. Comes as a material that constitutes the core. also, By housing the core in a flexible tubular bag, The core flows extremely quickly within the tubular bag. (8) the above washers, Solid components are ideal. Since the gasket has a solid construction, When the cover member is closed, local deformation such as lateral bending of the gasket can be prevented. The gasket will stably abut against the peripheral portion of the above opening. (9) The above tubular bag, The system can also be constructed of thin tubes with extensions. The core system can easily flow in all directions. therefore, The pad is more stably and evenly abutted with the peripheral portion of the opening. [Effects of the Invention] | According to the present invention, Flow deformation by internal pressure equalization, Even if the distance between the cover member and the body of the cold box is not constant, When the cover member is closed, the gasket interposed between the cover member and the cold box body is also abutted against both at equal pressure. therefore, Even in the case where the cold-retaining box body and the lid member which are resin molded articles are distorted, The internal pressure equalizer also flows and deforms to offset the distortion. the result, The cold storage chamber of the cold box body can be easily and surely sealed by simply closing the cover member.

The strut 22, The cover member 12 is engaged as will be described later. And when the cover member 1 2 is closed, The cover member 12 is surely held in a closed state. Again, Concave 21, The same shape as the recess 20, Further, a strut similar to the above-described stay 22 is disposed in the recessed portion 21. The strut 22 is respectively disposed on the side edge portion and the rear side edge portion of the upper end portion of the body 11, The cover member 12 can be opened and closed regardless of the front side or the rear side. but, Of course, the above-mentioned stays 22 may be provided on either of the front side or the rear side of the body 1 1 . Further, the cover member 12 is constructed so that it can be opened and closed only from either the front side or the rear side. Figure 3, Figure m is a cross-sectional view of m-ΠΙ. As shown in Figures 1 and 3, The cover member 12 is formed in a rectangular plate shape corresponding to the outer shape of the upper surface 15 of the body 1 1 . Cover member 1 2, The system has: Frame 23, And an inner cover 24 embedded in the outer frame 23. The outer frame 23 and the inner cover 24, Like the body 11, Formed from a resin (typically polypropylene). As shown in Figures 2 and 3, The outer frame 23 is provided with: The engaging claw 26 and the buckle 25 are provided. Engagement claws 26, They are respectively provided at the edge of the front side of the outer frame 23 and the edge of the rear side. And each of the clamping claws 26, It is disposed at a position corresponding to the stay 22 of the body 11 when the cover member 12 is closed. therefore, When the cover member 12 is closed, The engaging claw 26 is engaged with the stay 22, And the closed state of the cover member 12 is maintained. also, The above button 2 5, It is provided along the edge of the front side of the outer frame 23 and the edge of the rear side, respectively. The engagement of each of the engaging claws 26 with the stay 22 can be released. which is, When the buckle 25 is operated in a state where the cover member 12 is closed, Each of the engaging claws 26 will be separated from the stay 22, And untie the two, With this, The cover member 12 is 200800746 (12) and can be easily changed to the posture shown in Fig. 2. also, Since the above-described engaging claws 26 and the buckles 25 and the structure of the stays 22 are known, detailed descriptions thereof will be omitted. As shown in Figure 3, The inner cover 24 is embedded inside the outer frame 23. Inner cover 24, For example, it can be fixed to the outer frame 23 by bolts. A heat insulating material is placed inside the inner cover 24. The heat insulating material ' is, for example, a foamed poly-I female formic acid vinegar, Foamed resin such as foamed plastic. but, A vacuum heat insulating plate may be disposed by applying a foaming resin. An annular groove 27 (circumference ® groove) is formed around the inner surface 28 of the inner lid 24. The groove 27, When the cover member 12 is closed, It is disposed at a position facing the peripheral edge portion 17 of the opening 16 of the body 11. As shown in Figure 3, The groove 27, Opening on the inner face 28 of the inner cover 24, That is, the peripheral portion 17 side 〇 FIG. 4, An enlarged cross-sectional view of the main part of the cold box 10 The configuration of the body 11 and the cover member 12 is shown in detail. As shown in Figure 4, Figure 4, A gasket 18 is embedded in the groove 27, ^ A gap filling material 30 (internal pressure equalizer) is disposed between the gasket 18 and the bottom surface 29 of the groove 27. When the cover member 12 is closed, The inner cover 24 is opposed to the upper surface 15 of the body 1 1 . The washer 18 is pressed against the peripheral edge portion 17 of the opening 16 described above. With this, Closing the opening 16 described above, And the cold storage chamber 14 is sealed. Figure 5, The V-arrow view of Figure 4, The configuration of the gap filling member 30 and the gasket 18 is shown in detail. Washer 18 The cross-sectional shape is a rectangle. And the strip shape is formed as a whole. In this embodiment, The washer 18 is made of an elastomer (typically, Foamed rubber, It is composed of ethylene propylene triene copolymer (EPDM) and the like. Washer 18, The system has a solid construction of -15- 200800746 (13). The effect of the solid structure of the gasket 18 is described later. But pad 18, The system can also have a hollow structure. The height dimension H of the washer 18, It is set to a size corresponding to the depth of the groove 27. In short, The height dimension of the washer 18 is Η, Set to: In the state in which the gasket 18 is fitted into the groove 27, The upper end of the gasket 18 is protruded only a few millimeters from the opening 31 of the groove 27. also, Washer 18, Is embedded in the state of the groove 27, In Figure 5, you can slide up and down. therefore, Washer 18 By being pressed upwards in Figure 5, Can be retracted into the groove 27. Furthermore, ^ Pad 18, The system can also form a slender band. Embed along the long side of the above-mentioned groove 27, Or may form an endless loop, Embedded in the above groove 27. Gap filling coffin 30, The core portion 32 and the bag (tubular bag) 33 are provided. The gap is filled with the coffin 30, It is formed into an elongated strip shape. As mentioned above, Gap filling material 30, Arranged on the washer 18 in Figure 5, Further, the gap between the bottom surface 29 of the trench 27 and the pad 18 is compensated for. The length dimension of the gap filling material 30, Corresponding to the dimension of the long side of the groove 27, And the gap is filled with 0 coffin 30, The groove 27 is embedded in the longitudinal direction of the groove 27 described above. therefore, In a state in which the gap filling material 30 is embedded in the groove 27, The gap is filled at both ends of the material 30, They are opposed to each other and abut each other in the groove 27. However, The gap filling material 30 can also be formed into an endless loop. Embedded in the above-mentioned groove 27 芯 core portion 3 2, In the present embodiment, a gelatinous polyurethane is used. but, The material constituting the core portion 32 is not limited thereto. Can use grease, oil, A fluid substance such as water. also, As the material constituting the core portion 32, a sticky substance such as a slime can also be used. In short, The core 32 can be used as a non-compressible gel having a certain fluidity and viscosity, -16-200800746 (14) Liquid or mucus. also, Bag 33, It is made of flexible material. And formed into a tubular shape. The above core 32, It is housed in the bag 33. In this embodiment, The bag 33 is composed of a urethane sheet. The thickness of the urethane sheet constituting the bag 33, In the present embodiment, it is set to 3 5 μιη, But the thickness size, The system can be set to a degree of 5 μm to 50 μm. So, By accommodating the core 32 to the flexible bag 33, The core 32 is flowable in all directions. In other words, Gap filling coffin 30, The gel-like core portion 3 2 is flowed and deformed in a uniform pressure. The cold storage box 1 of the embodiment, As shown in Figures 1 and 2, The cover member 12 opens and closes the body 11 . Fisherman, By operating the handle 25 of the cover member 1 2, The cover member 12 can be opened, And by lodging the cover member 12, The engaging claws 26 of the cover member 12 are engaged with the stays 22, The cover member 12 is surely closed. also, Since the body 11 and the cover member 12 are made of a resin such as polypropylene, Therefore, there is an advantage that the constitution of the components is inexpensive. but, Since the body 1 1 and the cover member 12 are formed of a resin such as polypropylene, The body 1 1 and the cover member 1 2 as the product are distorted. For example, when the cover member 12 is distorted, The bottom surface 29 of the ground groove 27 is curved as shown in Fig. 4. thus, In a state where the cover member 12 is closed to the body 1 1 , The distance S1 between the peripheral edge portion 17 of the opening 16 of the body 11 and the bottom surface 29 of the groove 27 of the cover member 12 changes. which is, The distance S1 is not uniform with respect to the longitudinal direction of the groove 27. The distance S 1 between the peripheral edge portion 17 of the opening 16 and the bottom surface 29 of the groove 27 differs depending on the portion of the groove 27. In this case, Assuming that the gap filling material 30 is not provided, In the state in which the gasket 18 is embedded -17· 200800746 (15) into the groove 27, The height at which the washer 18 protrudes from the groove 27 changes. which is, The size of the pad 18 that bulges from the groove 27 will vary depending on the location of the groove 27. thus, When the cover member 12 is closed, In the portion where the gasket 18 protrudes from the groove 2 7 , The pad 18 is strongly pressed against the peripheral portion 17, on the other hand, Where the gasket 18 protrudes less from the groove 27, The washer 18 is pressed weakly against the peripheral portion 17 described above. The portion of the peripheral portion 17 is pressed weakly by the gasket 18, There is a possibility that the airtightness of the cover member 12 and the body 1 1 cannot be maintained. also, In the case where the gasket 18 is strongly pressed against the portion of the peripheral portion 17, It may be difficult to close the cover member 12 to the body 11. but, In the cold storage box 1 of the embodiment, Because the above gap is filled with the coffin 30, Therefore, when the cover member 12 is closed, Where the distance S 1 is small, Then, the gap filling coffin 30 becomes relatively high in an instant. also, Where the above distance S 1 is large, Then, the gap filling clinker 30 becomes a low pressure in phase. which is, In the inside of the gap filling member 30, a portion where the internal pressure is locally increased and a portion which is locally reduced are generated. So as to change by the internal pressure of the gap filling coffin 30, The gap is filled with the coffin 30, The internal pressure is deformed equally. that is, Gap filling material 3 0, It flows from the part with higher internal pressure to the lower part. Regardless of the above distance S1, Gap filling coffin 30, The gap between the washer 18 and the bottom surface 29 of the groove 27 flows and fills. With this, Even if the above distance S 1 is not constant, The distance S2 between the deformation washer 18 of the gap filling material 30 and the peripheral edge portion 17 of the opening 16 also becomes constant. therefore, The pad 18 is positively and uniformly pressed against the peripheral edge portion -18-200800746 (16) 17 of the opening 16. the result, Ontology 1 1, Is surely sealed by the cover member i 2 , And, Since the above distance S2 becomes constant, The operation of opening and closing the cover member 12 becomes easy. also, In this embodiment, The above gap filling material 30, By a liquid or gel-like core 32, And a bag 3 3 for accommodating the core portion 32, Therefore, the core portion 32 can flow extremely quickly into the pocket 33 at the moment of closing the cover member 12. By this, Gap filling material 30, The gap between the washer 8 and the bottom surface 29 of the groove 27 can be instantaneously filled. ® more, In this embodiment, Because the washer 18 described above has a solid construction, Therefore, local deformation of the lateral bending or the like of the gasket 18 can be prevented when the cover member 12 is closed. therefore, The washer 18 is stably abutted against the peripheral portion 17 of the opening 16, The body u can be reliably sealed by the cover member 12. Plus, In this embodiment, The bag 33 of the gap filling material 30, Made of a thin polyurethane tube, Rich and flexible. therefore, The above core 3 2, It can easily flow in all directions, With this, The gasket 18 has the advantage of being more stably and uniformly abutted with the peripheral edge portion 17 of the opening 16 described above. In this embodiment, The gap filling material 30, The core portion 32 having a non-compressive property is incorporated in a bag 33 having flexibility. therefore, In the manufacture of the gap filling material 30, The amount (volume) of the core 32 loaded into the bag 33 is an important management item. The volume of the core portion 3 2 can be accurately grasped by the weight of the core portion 32. that is, Even the core of liquidity 3 2, The management of its volume is simple. There is also the advantage that the manufacturing cost of the gap filling material 30 can be reduced. -19- 200800746 (17) Furthermore, The material constituting the bag 3 3 described above, Is not limited to urethane sheets, For example, synthetic rubber can be used. The type of synthetic rubber is not particularly limited. But it can also be an extended thing. When the synthetic rubber constituting the bag 33 is extensible, By accommodating the core 32 in the bag 33, The core 32 is more smoothly flowable in all directions. In other words, The bag 3 3 has a direction perpendicular to the long side or a direction perpendicular to the long side direction, Can be easily deformed, the result, The gel-like core portion 3 2 is flow-deformed under uniform pressure. Thus, in the case where the bag 33 is composed of an extensible material, The length of the gap filler 30, It can also be set to be shorter than the length direction of the groove 27. As mentioned above, On the occasion of closing the cover member 1 2, Changing by the internal pressure of the gap filling material 30, The gap filling member 30 is such that its internal pressure is uniformly deformed. that is, Gap filling material 30, It flows from the part with higher internal pressure to the lower part. Regardless of the size of the above distance S 1 (refer to Figure 4), The gap filling material 30 flows and is filled in the gap between the gasket 18 and the bottom surface 29 of the above-mentioned groove 27. at this time, Because the bag 33 is extensible, Therefore, the gap filling material 3 延伸 extends toward the long side, And after the two ends are close to each other, In a direction perpendicular to the direction of the long side, That is, it is deformed in the height direction. With this, Even if the above distance S 1 is not constant, By the gap filling the deformation of the material 30, The distance S2 between the washer 18 and the peripheral portion 17 of the opening 16 described above also becomes constant. therefore, The washer 18 is reliably and uniformly pressed against the peripheral portion 17 of the opening 16. Secondly, A modification of this embodiment will be described. Figure 6, An enlarged cross-sectional view of an essential part of a cold box according to a modification of the embodiment. -20- 200800746 (18) The cold box 40 of the present modification differs from the cold box 10 of the above-described embodiment in that the cold box 10' is provided with a groove 27 in the lid member 1 2 . And inserting the gap filling material 3〇 and the gasket 18 in the groove 27 In contrast, The cold box 40 of the present modification, a groove 2 7 ' is disposed on the side of the body 1 1 and a gap filling material 30 and a gasket 18 are embedded in the groove 27 at this point. Furthermore, regarding the other structure of the cold box 40, It is the same as the above-mentioned cold storage box. As shown in the figure, In the cold box 40, An opening 16 is also provided on the upper surface 15 of the body 11. then, A cold storage chamber 14 is formed in connection with the opening 16. ^ The above groove 27, The peripheral portion 17 of the opening 16 is provided. The groove 27, It is formed by cutting downwards in such a manner as to open on the upper surface 15 5 . Further, an annular shape is formed along the peripheral portion 17 described above. A gap filling member 30 is embedded in a depth portion of the groove 27, And, A gasket 18 is disposed on the gap filling material 30. Washer 18 As shown in the figure, only a few millimeters protrude from the above upper surface 15 5 . And by closing the cover member 12, The pad 18 abuts against the inner surface of the cover member 12 〇 ^ In the present modification, Because the gap filling material 30 is also provided, Therefore, when the cover member 12 is closed, a portion where the distance S1 between the bottom surface 29 of the groove 27 and the inner surface 42 of the cover member 12 is small, Then, the gap filling coffin 30 becomes relatively high in an instant. also, Where the above distance S 1 is large, Then, the gap filling material 30 becomes relatively low in an instant. which is, A portion where the internal pressure locally becomes large and a portion which becomes locally smaller are generated inside the gap filling material 30. When the internal pressure of the gap filling material 30 changes, As mentioned above, The gap filling material 30 is such that its internal pressure is uniformly deformed. that is, The gap filling material 3 0 ' flows from the portion where the internal pressure is high to the lower portion. And regardless of the size of the distance S 1 -21 - 200800746 (19) The gap filling material 30 is caused to flow in the gap between the gasket 18 and the bottom surface 29 of the groove 27 and is filled. With this, Even if the above distance S1 is not constant, By the deformation of the gap filling coffin 30, The distance S2 between the washer 18 and the inner face 42 of the cover member 12 also becomes constant. therefore, The washer 18 is positively and uniformly pressed against the inner face 42 of the cover member 12. the result , Ontology 1 1, Is surely sealed by the cover member 1 2, and, Since the above distance S2 becomes constant, The operation of opening and closing the cover member 12 becomes easy. $ Second, Other modifications of the embodiment will be described. Figure 7, An enlarged cross-sectional view of a gasket according to another modification of the embodiment. The washer 45 of the present modification differs from the washer 18 of the above embodiment in that: The washer 45 has a hollow structure. And sealing the core portion 32 inside, at this point. The material that makes up the mattress 45, Made of foamed rubber, It is composed of an elastomer such as ethylene propylene triene copolymer (EPDM). also, The material constituting the core portion 3 2 , A gelatinous polyurethane can be used as described above. But φ , The material constituting the core portion 32 is not limited thereto. It can also be greased, Oil, a fluid substance such as water, a sticky substance such as mucus. In short, The core 32 can be made of a non-compressible gel having a certain fluidity and viscosity. Liquid or mucus. As shown in Figure 7, The washer 4 5 series is equipped with: a pair of side wall portions 46, 4 7 , And thick bottom 48, And a top plate portion 49, The core portion 32 is housed in the space 50 divided by the above. Side wall portion 46, 47, It is thinner than others. Since the core is fluid as described above, Therefore, it can be injected into the pad 45 by means of an injector or the like. Specifically, Insert the needle of the syringe into the platform -22- 200800746 (20) Part 4 8, The core portion 3 2 is injected into the above space 50. at this time, For example, with other syringes, It is desirable to discharge pre-existing air in the space 50. The washer 45, The first embodiment and the modified example are embedded in the main body 1 1 or the cover member 1 2, But at this time, The thick bottom 48 side is inserted into the groove 27 provided in the body 1 1 or the cover member 12. This modification, The core 32 is received in the gasket 45, Therefore, in the cold box 10, 40 assembly, Only a single member (i.e., the washer 45) can be loaded into the body 11 or the cover member 12, Therefore, assembly work becomes easy. and, There is no need to accommodate the bag 33 of the core 32, Therefore, the number of parts can also be reduced. also, The side wall portion 46 of the pad 45, 47 is formed thinner than the thick bottom portion 48 and the top plate portion 49, Therefore, the mattress 45 is easy to bend, The core 32 can flow rapidly within the space 50.
