脫自如地覆蓋前述中栓之栓帽蓋；且前述中栓在具有嵌固 在其外周上之填塞件，藉由前述螺紋部而在前述栓本體固 定在前述容器上之狀態下，前述填塞件係介存於前述容器 154665.doc 201144169 的内周與月.j述中检的外周之間；前述螺紋部係設置在前述 栓/罩之内周上’前述填塞件係在前述中栓之外周内，自螺 :1向亡面臨刖述螺紋部之部位嵌固在所設之填塞件支持 p上月』述中栓與前述栓罩相較於前述填塞件支持部係在 軸向栓帽蓋側之部位扣脫自如地被扣止4，「轴向」係 U紋部的轴線之方‘針對遍及環㈣向的中心之周 向連績之周圍’在相同軸向位置為二重之周圍Μ，將内側 之周圍稱為「内周」’外側之周圍稱為「外周」。 若將谷器口栓的螺紋部設置在栓罩的内周上則無須如 專利文獻1之物件般在中栓的外周上設置螺紋部，而可在 中栓之外周内自螺紋徑向上面臨螺紋部之部位設置填塞件 支持部。藉此，由於可使填塞件之密封位置靠近栓帽蓋 侧，因此在容器内可確保容量在軸向上較大。甚至即使確 保相同容量，亦可將容器小型化。 由於可使中栓與栓罩相較於填塞件支持部在軸向栓帽蓋 側之部位扣脫自如地扣止，因此在清掃栓罩的内周與中栓 的外周間之間隙内之時，可將中栓自栓罩上卸除，而使清 潔性良好。又，由於在卸除中栓之狀態下可將填塞件扣在 填塞件支持部上或使其脫離，因此即使在中栓的外周内自 螺紋徑向上面臨螺紋部之部位設置填塞件支持部，亦無須 顧慮填塞件之扣脫變得困難。 例如’可構成為：前述中拴具有在周向複數個部位相較 於自身之内外周更朝轴向栓帽蓋側突出之扣止爪，前述检 罩具有與前述扣止爪扣合之爪接受部，藉由使前述中检之 154665.doc • 6 - 201144169 扣止爪相對於前述爪接受部於軸向觸及並彈性傾斜而越過 該爪接受部進行彈性回復，而到達至彼此在軸向上扣合之 位置，前述栓帽蓋在安裝於前述栓本體之狀態下，係將前 述扣止爪之傾斜限制在無法自前述爪接受部脫出之範圍 内。 作為扣脫自如地扣止中栓與栓罩之構造，可採用前述之 扣止爪與爪接受部。扣脫式之栓帽蓋可以在安裝於栓本體 上之狀態下將扣止爪之傾斜限制在無法自爪接受部脫出之 範圍内之方式設置。以上述方式，即使中栓誤相對於轴向 朝對應於扣止爪之傾斜方向之側強行被傾斜，亦可利用栓 帽蓋防止扣止爪自爪接受部脫出。 較佳的疋，前述栓帽蓋具有插入至前述中栓的内周内側 之筒部、以及嵌固於該筒部的外周上之帽蓋填塞件，並由 扣脫自如地覆蓋前述中栓的凹入空間之前述栓帽蓋與該中 栓形成絕熱室’前述帽蓋填塞件密封前述中栓的内周與前 述筒部的外周之間，前述筒部係限制前述扣止爪之傾斜。 由於扣脫自如地覆蓋中栓的凹入空間之检帽蓋具有插入 至令栓的内周内側之筒部’因此可由栓帽蓋與中栓形成絕 熱室。若由嵌固於該筒部的外周之帽蓋填塞件密封中检的 内周與前述筒部的外周之間，則即使由筒部限制自中检的 内周突出至軸向栓帽蓋側之扣止爪的傾斜，亦無須顧慮飲 料浸入至絕熱室内。由於可利用絕熱室形成用之筒部進行 扣止爪之傾斜限制’因此無須在栓帽蓋上追加傾斜限制專 用之壁。 154665.doc 201144169 若採用本發明之容器口栓，則可構成為例如以下構造之 飲料容器：前述容器包含接合内容器與外容器而成之二重 絕熱容器’前述内容器之最小内徑部存在於在前述外容器 之肩部以上靠近軸向栓帽蓋側之部位，前述外容器具有在 前述螺紋部螺合之外螺紋，且在前述检本體固定於前述容 益上之狀態下’前述栓罩係藉由前述外容器的肩部支撐於 轴向，且介存於前述填塞件與前述内容器的最小 ' 間。 口1 < 如上述般，本發明之容器口栓由於可將密封容器的内周 與中检的外周之間之填塞件的密封位置靠近检帽蓋側，因 此可在外容器的肩部以上以存在於#近軸向栓帽蓋側之部 =之方式設置内容器的最小内徑部。先前，如專利文獻i 般，由於使内容器的最小内徑部相較於外容器的肩部係位 於靠近底側之部位’因此相較於其，可在無須將外容器在 軸向上延長下’即可使内容器的最小内徑部靠近栓帽蓋 側而確保内容器的容量在軸向上較大。因而，即使確保 相同今置，因可使内容器底部提高，故可將容器小型化。 [發明之效果] 如上述般，由於本發明藉由採用上述構成，可無須在中 栓的外周上設置螺紋部’即可使填塞件的密封位置靠近栓 帽蓋側’因此可將容器小熟，且在清掃栓罩的内周與中 栓的外周間之間隙内時由於可將中栓自栓罩卸除，故而可 良好地保持清潔性，由於在中拴卸除之狀態下可在填塞件 支持部扣合填塞件或使其脫離，因此亦不會有該作業會變 I54665.doc 201144169 得困難之顧慮。 【實施方式】 以下，茲基於附圖說明本發明之第一實施形態。如圖1〜 圖3所不般’第一實施形態為具有容器1、在轴向上可扣合 於谷器1的口部内周或自其脫離之嘴口構件2及容器口栓之 ㈣谷器。容器口栓具備：具有在容器【上螺旋扣脫自如 的螺紋部31、自軸向蓋到容器1的栓罩32及自該栓罩32於 抽向凹入的中栓33之栓本體3 ;以及扣脫自如地覆蓋中栓 33的凹入空間之栓帽蓋4。中栓33具有嵌固在其外周上之 填塞件34。由栓帽蓋4與中栓33形成絕熱室5。在藉由螺紋 431使栓本體3©定在容器丨上之狀態下，填塞们4係介存 於容器1的内周與中栓33的外周之間。 谷盜1係為内容器11與外容器12接合成之二重絕熱容 器二：器1包含例如真空二重容器。容器1具有在上面開放 之容器口。内容器1卜外容器12分別為不鑛鋼薄板製，且 周圍 '屋拉延而形成有肩部及頸部。形成於内容器11的頸部 之最小内徑部11a如圖示所明確化般，係存在於在外容器 12的肩部以上靠近軸向栓帽蓋側之部位”卜容器η具有可 螺合於螺紋㈣之外職12ae在使栓本體㈣定於容以 之狀態下’可藉由外容器12的肩部在軸向上支樓栓罩& 且使其介存於填塞件34與内容器u的最小内徑部山之 間。嘴口構件2可省略。 螺紋部31包含在容器1上螺合之螺軸部。伴隨在容器工上 設置外螺紋i2a，螺紋部31係被設置在检罩32的内周上。 154665.doc 201144169 軸向為相對於水平之上下方向。圖中上下方向之一點鏈線 係螺紋部3 1之軸線，亦即表示軸向。螺紋徑向為水平方 向。圖中左右方向之一點鏈線表示螺紋徑向。 如圖1、圖4所示般，栓罩32係由：螺紋部31形成在内周 上之罩本體35、自軸向蓋到罩本體35的上部之裝飾板％、 及與罩本體35—起包夾裝飾板36而固定之按壓構件”構 成罩本體3 5及按壓構件3 7分別係經射出成形而形成。裝 飾板36具有金屬表面。裝飾板36係由對於罩本體”之重疊 而定位在螺紋徑向及軸向填塞件34側。按壓構件37可自軸 向蓋到在罩本體35上重疊之裝飾板36的内周及上面的内周 側。按壓構件37具有自周向複數個部位朝軸向填塞件34側 大出之爪部37a。爪部37a係如上述般自軸向覆蓋期間，藉 由與罩本體35的内周邊緣之觸及而彈性傾斜，藉此越過該 内周邊緣而彈性回復，而到達至彼此在軸向上扣合之位 置。藉由此等爪部37a與罩本體35的周向複數個部位之扣 合，使罩本體35、裝飾板36及按壓構件37結合為一體。 如圖1、圖3所示般，中栓33係由具有自栓罩32朝軸向填 塞件34側凹入之内外周，且使其凹入空間在轴向上開放之 構件所構成。在中栓3 3的外周内，螺紋徑向上面臨螺紋 部31之部位設置有可將填塞件34自軸向嵌固之填塞件支持 部33a °填塞件支持部33a在將栓本體3螺合在容器1上之 時可將填塞件3 4相對於中栓3 3的外周在軸向偏離移動之 範圍限制在正規範圍内。「正規範圍内」係指可確保不透 水地毪封中栓33與内容器丨丨的内周之間之狀態之範圍内。 154665.doc 201144169 形成在填塞件34的外周之圓筒面的軸向中間區域被壓入至 内容器11的最小内徑部lla，並藉由基於該等必要程度之 緊固之农著，而成為能夠確保不透水地被密封之狀態之範 圍内。 填塞件支持部33a具有在圓周方向上之圖中下側之突條 部及圖中上側之突條部填塞件34具有以剖面〕字狀在圓 周方向上連續之嵌合部。藉由在填塞件支持部33a的圖中 下側之犬條部壓入填塞件34的嵌合部，而限制填塞件34之 朝軸向填塞件側之位移。轴向填塞件側係對應於圖中下 側。朝填塞件34的圖中上側之位移係由利用填塞件支持部 3 3a之圖中上側的突條部之支撐被限制。 如圖1、圖2所示般，中栓33與栓罩32係相較於填塞件支 持部33a在軸向栓帽蓋側之部彳立被扣脫自如地扣止。軸向 栓帽蓋側係對應於圖中上側。 具體而言，中栓33具有於周向複數個部位相較於自身之 内外周在軸向栓帽蓋側突出之扣止爪33b。栓罩32具有與 扣止爪33b扣合之爪接受部37b ^爪接受.部37b係設置在按 壓構件37上。中栓33之扣止爪33b係藉由相對於對應於周 向之爪接受部37b於軸向觸及並彈性傾斜而越過該爪接受 部進行彈性回復，而到達至彼此在軸向上扣合之位置。藉 由該等扣止爪33b與爪接受部37b之周向複數個部位之扣 合’而使中栓33與栓罩32結合為一體。 中栓33具有：包含填塞件支持部33a之外周、扣止爪 33b、及在扣止爪33b的周向兩側以空隙33c而相較於自身 154665.doc 201144169 之内外周突出於軸向栓帽蓋側之抵接壁33cl。抵接壁33d# 在將中栓33扣止於栓罩33之狀態下與栓罩32在轴向上抵 接。利用該抵接，使中栓33以相對於栓罩32無法往轴向检 帽蓋側位移之方式定位。另’在扣止爪33b與栓罩之 間，確保有用以容許扣止爪33b的傾斜之軸向間隙。扣止 爪33b係在螺紋徑向上以一對設置。因此，藉由以手指夾 著2個部位之扣止爪33b，可易於按壓所有的扣止爪33b並 在前述之傾斜方向上強制性壓倒，而解除扣合。在其解除 後’可將中栓33與栓罩32在軸向上原狀分離。 中栓33與栓罩32間之周向定位係源於形成在爪接受部 37b的周向兩側之規制壁37(；與扣止爪33b之周向扣合。為 對應於以圓周狀形成絕熱室5或容器丨之内外周，而謀求中 栓33及栓罩32亦以整體在圓周状的内外周上設置。由於可 獲得利用各扣止爪33b與規制壁37c之周向定位，因此即使 未在中栓33與栓罩32之間設置其他周向定位構造，亦可使 中栓33相對於栓罩32在圓周方向上禁止轉動。 如圖1、圖5所示般，栓帽蓋4具有插入至中栓33的内周 内側之筒部41與嵌固在該筒部4丨的外周之帽蓋填塞件4 2。 帽蓋填塞件42可密封中栓33的内周與筒部41的外周之間。 栓帽蓋4之頂面係以沿正交於軸向之平面之方式形成。為 了消除因設置栓罩32的爪接受部37b而使栓帽蓋4的頂面形 成壁43部分或是整體朝軸向外側膨出之必要，使爪接受部 37b以相較於抵接壁33d與栓罩32之抵接位置朝軸向填塞件 側凹入之方式設置。 154665.doc •12· 201144169 栓帽蓋4可在將栓罩32與中栓33如上述般結合而組裝栓 本體3之狀態下，自軸向蓋到栓本體3上。栓帽蓋4的對羚 栓本體3之固著力係源於帽蓋填塞件42與中栓33的内周間 之密著。由覆蓋中栓33的凹入空間之栓帽蓋4的筒部41、 帽蓋填塞件42及頂面形成壁43、以及中栓3 3形成絕熱室 5。為活用中栓33之凹入深度而獲得絕熱室5的容量，並相 較於填塞件34之密封位置（最小内徑部Ua)不為低，在中拴 33之凹入底面内，形成絕熱室$的底面最深部之部位，相 較於填塞件34的密封位置乃為軸向栓帽蓋側，且相較於位 於螺紋部3 1的最軸向栓帽蓋側之螺紋開始端形成地較低。 又，為獲得絕熱室5的容量，在頂面形成壁43内，成為絕 熱室5的天花板之部分會相較於栓罩32在轴向上形成為較 咼。由於有帽蓋填塞件42之密封，因此即使利用中栓33之 空隙33c形成扣止爪33b，亦無須顧慮自空隙33c朝絕熱室5 浸水。另，清掃時所附著之水滴或攝取飲料時相較於填塞 件34更在栓帽蓋4側附著之殘留液滴有可能自空隙33c到達 至栓帽蓋4的頂面形成壁43與栓罩32之間。為此，栓帽蓋4 之筒部41的外周及頂面形成壁43與栓罩32之間隙以遍及全 周以至外部之方式確保。因此，藉由適當地搖動容器口栓 可將其水滴等排出至外部。 可於在检本體3上扣脫自如的栓帽蓋4上設置自軸向插入 之用以容許前述扣止爪33b的傾斜之空間之傾斜限制部 44。栓巾目蓋4的傾斜限制部44係以安裝在栓本體3上之狀態 將扣止爪33b的傾斜限制在無法自爪接受部37b脫出之範圍 154665.doc •13- 201144169 内。因此’即使誤使中栓3 3相對於軸向朝對應於扣止爪 3 3 b之傾斜方向之側強行傾斜，且扣止爪3 3 b壓接於爪接受 部37b ’亦可利用栓帽蓋4而防止扣止爪33b自爪接受部37b 脫出。 具體而δ，傾斜限制部44係利用作為朝中栓33的内側掉 入部分之筒部41而被設置。筒部41之傾斜限制部44可自中 栓33的内側限制扣止爪33b之傾斜。藉由筒部41之利用， 相較於自筒部41離開而突出專用的傾斜限制部之情形，可 避免栓帽蓋4之壁面構造的複雜化。另，傾斜限制部料係 部分在螺紋徑向上突出於筒部41的外周上。如此使傾斜限 制部44如肋條般部分突出只是為避免無用之加工。傾斜限 制部44為消除例如與扣止爪331?之周向位置配合之要可 以在外周全周上突出之方式設置。 由於係在周向上部分設置傾斜限制部44，因此為避免傾 斜限制部44自支撐扣止爪33b之範圍在周向脫出，需要進 行栓帽蓋4與栓罩32間之周向定位。該定位源於检帽蓋*的 頂面形成壁43與圖4所示之栓罩32的第二規制壁37d之周向 扣合。由於第二規制壁37d係與爪接受部37b等一起由相同 模具成形，因此為部分朝軸向填塞件側凹入之形狀。如圖 卜圖3所示般，與栓罩32與中检33相同，检帽蓋々之筒部 Μ被要求以整體設置在圓周狀的内外周上。由於可獲得 利：圖4 ® 5所不之第二規制壁37d與頂面形成壁G之周 向定位’因此如圖i、圖3所示般，即使在栓罩32與检帽蓋 4之間未設置其他周向^位構造，亦可將栓帽蓋4相對於检 154665.doc -14. 201144169 罩32在圓周方向上禁止旋轉。 另’中栓33係利用射出成形而設置成一個構件。中栓33 月色以一個零件自栓罩3 2分離即可，但若結合複數個構件而 設置中栓’則會使零件數增加，而導致結合間隙之清掃較 麻煩。 上述之第一實施形態若將中栓33自栓罩32分離，則包含 安裝有填塞件34之填塞件支持部33a之中栓33的外周及相 較於該外周在軸向栓帽蓋側之扣止爪33b、抵接壁33d會自 栓罩32上分離》因而，如圖1般，形成栓罩32的内周與中 栓33的外周間之間隙之栓罩32的内周及下面會因中栓33消 失而露出較大》因此，會易於直接清掃栓罩32的内周及下 面。如此，第一實施形態可良好地保持栓罩32的内周與中 栓33的外周間之間隙内的清潔性/又，自分離之中栓^可 將填塞件34在不妨礙其他構件之情形下對於填塞件支持部 33a進行簡單地扣合或自其脫離。 由於係將容器口栓之螺紋部3丨設置在栓罩3 2的内周，因 此在中栓33的外周内自螺紋徑向上面臨螺紋部31之部位設 置填塞件支持部33a ^藉此，由於可將填塞件34的密封位 置罪近栓帽蓋4側，因此可在容器丨内確保容量在軸向上較 大。甚至即使確保相同容量’亦可將容器i小型化。亦 f7在包a —重絕熱容器之容器丨中，由於是以存在於在 外合器12的肩部以上靠近軸向栓帽蓋4側之部位之方式設 置内容器11的最小内徑部lla ’因此無須將外容器12在軸

第二貫施形態可省略裝飾板等，由一個零件構成栓罩6工。 栓罩61可代替按壓構件，具有自上面部的内周邊緣延伸向 軸向填塞件側之第二内周壁。又，中栓62與栓罩61之扣止 為快速卡脫結合構造。栓帽蓋63的筒部會與形成令栓Μ的 内外周之壁部在軸向上頂接而形成絕熱室’其並未插入至 中栓62的内周内側。因此，可將絕熱室大容量化❹另，栓 罩61的第二内周壁與栓帽蓋63的筒部之間係由帽蓋填塞件 密封。 快速卡脫凹槽64係設置在中栓62的外周上。快速卡脫爪 65係於栓罩61的周向複數個部位自第二内周壁朝轴向填塞 件側突出。如圖8⑷、圖8(b)所示般，若在快速卡脫結合 後將检帽蓋63安裝在栓本體上’則如圖8(e)所示般，可使 栓帽蓋63的堵塞部66自快速卡脫凹槽料的插入口在軸向上 插入至凹槽内。藉由該堵塞部66，可確實防止朝快速卡脫 爪65之解除旋轉側之位移。

Description of the Invention: [Technical Field of the Invention] The present invention relates to a container port plug which can be detached from a container and a beverage container provided therewith. 〃 [Prior Art] π Previously, as a container port plug for a beverage container, there was provided a threaded portion having a screw-fast release on the container, a cap from the axial cover to the container, and a cap from the cap. a plug body that is recessed into the middle of the recess; and a latch cap that freely covers the recessed space of the middle plug... the plug has a stuffing member embedded on the outer circumference thereof, and the plug cap and the middle bolt form an insulating chamber, And in a state in which the plug body is fixed to the container by the thread portion, the stuffing member is an object interposed between the inner circumference of the container and the outer circumference of the middle pin. Since the bolt body is detachably fixed to the container by the threaded portion of the bolt cover, the middle bolt and the bolt cover can be integrated by welding, forced fitting, or the like. The container is provided with a thread for the outer or outer thread of the container. The threaded portion of the container mouth plug is provided on the outer circumference of the middle bolt in the case where the container has an internal thread, and is disposed on the inner circumference of the bolt cover in the case of the container member = external thread (Patent Document 1). [Patent Document] [Patent Document 1] Japanese Patent Laid-Open No. Hei 10-272068 [Draft of the Invention] [Problems to be Solved by the Invention] Such a container port plug has a check from the axial cover to the outer periphery of the container. The cover and the plug from the axial recess of the plug cover are thus inserted into the mouth of the container formed on the inner circumference of the bolt cover and the middle of the test in the direction of the 154665.doc * 4 · 201144169 Pour out the drink, or close the mouth; within the gap. If the material is left, the beverage will adhere to the outer periphery of the container 2, and the food will adhere to the inside of the mask in the gap; the material will be heated to the heat-insulating The inner circumference of the cover and the barrier: The test is less preferred, and the width is narrow. The gap between the three doors is as much as possible! And in the case of = cleaning the beverage attached to the gap. There will be a disassembly for the cleaning of the stuffing piece (4). For easy removal _# 1 axial A plug is placed on the outer circumference of the plug. The 卩 is embedded here. If the plug is placed in the axial direction, the tampon support portion is provided: the tampon is brought into contact with the inner circumference of the container. The sealing position of the sealing surface is set to the inside of the container in the axial direction. This will reduce the capacity of the container in the upward direction, which may cause a problem of miniaturization of the container. The problem of the present invention is that it can be good. The container (4) is miniaturized under the cleanliness in the gap between the inner circumference of the bolt cover and the outer circumference of the middle bolt. [Technical means for solving the problem] In order to solve the above problem, the composition of the invention container port plug has: a threaded portion which is freely screwed on the container, a hood which is self-axially covered to the thief, and a yoke body of the middle yoke from the yoke in the axial direction, and the detachable cover a plug cap; and the plug is embedded in the outer periphery of the plug, the threaded portion of the plug body is fixed on the container, the plug is stored in the container 154665. Within doc 201144169 Between the outer circumference of the month and the middle of the inspection; the threaded portion is disposed on the inner circumference of the bolt/cover. The aforementioned tamping member is in the outer circumference of the middle bolt, and the snail is facing the thread portion. The portion is embedded in the tampon-holding member provided by the previous month. The middle shackle is buckled and detached from the tying cover at the side of the axial ferrule cap side. The axis of the axis of the U-shaped portion is 'around the circumference of the center of the ring (four) direction. 'The circumference is the double in the same axial position, and the inner side is called the "inner circumference". The circumference is referred to as "outer circumference." If the threaded portion of the barge plug is placed on the inner circumference of the bolt cover, it is not necessary to provide a threaded portion on the outer circumference of the middle bolt as in the object of Patent Document 1, but it can be placed in the middle of the bolt. A tampon support portion is provided in a portion of the outer circumference that faces the threaded portion in the radial direction of the thread. Thereby, since the sealing position of the tamping member can be brought close to the side of the cap, the capacity can be ensured to be large in the axial direction in the container. Even if the same capacity is ensured, the container can be miniaturized. Since the middle bolt and the bolt cover can be buckled freely on the side of the axial plug cap side than the stuffer support portion, when the inner circumference of the sweep bolt cover and the outer circumference of the middle bolt are in the gap The middle bolt can be removed from the bolt cover to make the cleaning property good. Further, since the tamping member can be fastened or detached from the tamping support portion in a state in which the middle yoke is removed, even if the tampon support portion is provided in the outer circumference of the middle yoke from the thread portion facing the thread portion in the radial direction, There is no need to worry about the difficulty of the detachment of the stuffing. For example, the middle middle can have a locking claw that protrudes toward the axial plug cap side from the inner and outer circumferences of the plurality of portions in the circumferential direction, and the inspection cover has a claw receiving portion that is engaged with the locking claw. By causing the aforementioned 154665.doc • 6 - 201144169 buckle claws to be axially contacted and elastically inclined with respect to the aforementioned claw receiving portion, elastically recovering over the claw receiving portion, and reaching to each other in the axial direction In the position where the cap is attached to the plug body, the inclination of the latching claw is restricted to a range in which the claw receiving portion cannot be removed. As the structure for releasing the middle bolt and the bolt cover freely, the above-described buckle claw and claw receiving portion can be employed. The buckle cap can be placed in such a manner that the inclination of the pawl is restricted to a range in which it cannot be released from the claw receiving portion while being attached to the plug body. In the above manner, even if the middle pin is forcibly tilted with respect to the axial direction toward the side corresponding to the tilting direction of the locking claw, the cap can be prevented from coming out of the claw receiving portion by the cap. Preferably, the cap is provided with a tubular portion inserted into the inner circumference of the inner middle of the middle plug, and a cap packing embedded on the outer circumference of the tubular portion, and the cover is freely covered by the middle plug. The capping cover of the recessed space and the middle plug forming heat insulating chamber' are sealed between the inner circumference of the middle plug and the outer circumference of the tubular portion by the cap filling member, and the tubular portion restricts the inclination of the locking claw. Since the cap that freely covers the recessed space of the middle pin has a tubular portion inserted into the inner side of the inner periphery of the pin, the cap can be formed by the cap and the middle pin. If the inner circumference of the cap seal is sealed between the outer circumference of the cap and the outer circumference of the barrel, the inner circumference of the inner tube is restricted from the middle portion to the side of the axial cap. The inclination of the claws does not require the beverage to be immersed in the heat insulation chamber. Since the inclination of the claws can be restricted by the cylindrical portion for forming the heat insulating chamber, it is not necessary to add a special wall for tilting the cap to the cap. 154665.doc 201144169 If the container mouth plug of the present invention is used, it may be configured, for example, as a beverage container having the following structure: the container includes a double insulated container formed by joining an inner container and an outer container. The outer container has a thread that is screwed to the threaded portion above the shoulder of the outer container, and the threaded portion is fixed to the aforementioned capacity. The cover is supported in the axial direction by the shoulder of the outer container and is interposed between the aforementioned packing member and the minimum of the inner container. Port 1 < As described above, the container port plug of the present invention can be placed above the shoulder of the outer container because the sealing position of the packing member between the inner circumference of the sealed container and the outer circumference of the medium inspection can be brought closer to the inspection cap side. The smallest inner diameter portion of the inner container is provided in the manner of the portion near the side of the proximal axial cap. Previously, as in the patent document i, since the minimum inner diameter portion of the inner container is located closer to the bottom side than the shoulder portion of the outer container, it is possible to extend the outer container in the axial direction without being compared thereto. 'The smallest inner diameter portion of the inner container can be brought close to the side of the cap cover to ensure that the capacity of the inner container is larger in the axial direction. Therefore, even if the same is ensured, the bottom of the inner container can be increased, so that the container can be miniaturized. [Effects of the Invention] As described above, according to the present invention, it is possible to provide the sealing position of the tamping member close to the side of the cap cap without having to provide the threaded portion on the outer circumference of the middle pin, so that the container can be cooked slightly. Moreover, since the middle bolt can be removed from the bolt cover when the inner circumference of the sweep bolt cover and the outer circumference of the middle bolt are removed, the cleanability can be well maintained, and the plug can be filled in the state of being removed from the middle jaw. The support part is snapped or detached, so there is no concern that the operation will become difficult. [Embodiment] Hereinafter, a first embodiment of the present invention will be described based on the drawings. As shown in FIG. 1 to FIG. 3, the first embodiment is a (four) valley having a container 1 that can be engaged with or removed from the inner circumference of the mouth of the barr 1 in the axial direction. Device. The container mouth plug has: a plug body 32 having a threaded portion 31 on the upper side of the container, a bolt cover 32 from the axial cover to the container 1, and a plug body 3 for drawing the recessed central plug 33 from the bolt cover 32; And a cap cap 4 that freely covers the recessed space of the middle pin 33. The middle pin 33 has a packing member 34 that is fitted to the outer periphery thereof. The heat insulating chamber 5 is formed by the cap cap 4 and the middle pin 33. In a state in which the plug body 3© is placed on the container by the thread 431, the packing 4 is interposed between the inner circumference of the container 1 and the outer circumference of the middle pin 33. The grain thief 1 is a double insulated container 2 in which the inner container 11 and the outer container 12 are joined. The device 1 includes, for example, a vacuum double container. The container 1 has a container opening that is open on the top. The outer container 12 of the inner container 1 is made of a non-mineral steel sheet, and a shoulder and a neck are formed by the surrounding 'house'. The minimum inner diameter portion 11a formed on the neck portion of the inner container 11 is affixed to the portion of the outer container 12 above the shoulder portion of the outer container 12 near the axial plug cap side. Thread (4) The external position 12ae can be placed in the axial direction by the shoulder of the outer container 12 by placing the plug body (4) in a state where it can be accommodated and placed in the stuffer 34 and the inner container u The minimum inner diameter portion is between the mountains. The mouth member 2 can be omitted. The threaded portion 31 includes a screw shaft portion screwed on the container 1. With the external thread i2a provided on the container, the thread portion 31 is disposed in the mask The inner circumference of 32. 154665.doc 201144169 The axial direction is the upper and lower direction with respect to the horizontal direction. One of the points in the up and down direction in the figure is the axis of the threaded portion 3 1 , that is, the axial direction. The radial direction of the thread is horizontal. The one-point chain line in the middle and left direction indicates the thread radial direction. As shown in Fig. 1 and Fig. 4, the bolt cover 32 is composed of a threaded portion 31 formed on the inner circumference of the cover body 35, and from the axial cover to the cover body 35. The upper decorative panel %, and the pressing member fixed to the cover body 35 to sandwich the decorative panel 36" Into the cover main body 35 and the pressing member 37 are formed by injection molding by the system. The trim panel 36 has a metal surface. The decorative panel 36 is positioned on the side of the thread radial and axial packing 34 by the overlap of the cover body. The pressing member 37 can be self-axially covered to the inner circumference and the upper surface of the decorative panel 36 overlapping the cover body 35. The inner peripheral side. The pressing member 37 has a claw portion 37a that is formed toward the axial packing 34 side from a plurality of portions in the circumferential direction. The claw portion 37a is covered by the inner circumference of the cover body 35 during the axial covering as described above. The edges are elastically inclined by the contact of the edges, thereby elastically recovering over the inner peripheral edge, and reaching positions that are axially engaged with each other. Thereby, the claw portions 37a are engaged with the plurality of portions of the cover body 35 in the circumferential direction. The cover body 35, the decorative plate 36, and the pressing member 37 are integrated into one body. As shown in Fig. 1 and Fig. 3, the middle pin 33 is formed by the inner and outer circumferences having the self-plug cover 32 recessed toward the axial packing member 34 side. And the recessed space is formed by the member which is open in the axial direction. In the outer circumference of the middle bolt 3 3 , the portion of the thread facing the thread portion 31 in the radial direction is provided with a stuffing member which can insert the stuffing member 34 from the axial direction. The portion 33a ° stuffing member support portion 33a can be used when the plug body 3 is screwed onto the container 1. The extent of the axial displacement of the packing member 34 relative to the outer circumference of the middle bolt 3 3 is limited to a regular range. "Regular range" means the inner circumference of the plug 33 and the inner container 可 which are ensured to be impervious to water. Within the scope of the state. 154665.doc 201144169 The axially intermediate portion of the cylindrical surface formed on the outer circumference of the packing member 34 is pressed into the minimum inner diameter portion 11a of the inner container 11 and is secured by the fastening based on the necessary degree. It is within the range of being able to ensure that it is sealed in a watertight manner. The wadding support portion 33a has a ridge portion on the lower side in the drawing in the circumferential direction and a ridge portion 34 on the upper side in the drawing, and has a fitting portion that is continuous in the circumferential direction in a cross-sectional shape. The displacement of the caulking member 34 toward the axial packing side is restricted by pressing the fitting portion of the wadding member 34 on the lower side of the damper support portion 33a in the drawing. The axial packing side corresponds to the lower side of the figure. The displacement toward the upper side in the drawing of the packing member 34 is restricted by the support of the ridge portion on the upper side in the drawing by the tamping member supporting portion 3 3a. As shown in Fig. 1 and Fig. 2, the middle pin 33 and the bolt cover 32 are detachably fastened from each other on the side of the axial plug cap side of the stuffer support portion 33a. The axial pin cap side is corresponding to the upper side of the figure. Specifically, the middle pin 33 has a locking claw 33b that protrudes in the circumferential direction of the plurality of portions on the side of the axial bolt cap in comparison with the inner and outer portions of the inner portion. The bolt cover 32 has a claw receiving portion 37b that is engaged with the locking claw 33b. The claw receiving portion 37b is provided on the pressing member 37. The latching claws 33b of the middle pin 33 are resiliently retracted beyond the claw receiving portion by being axially touched and elastically inclined with respect to the claw receiving portion 37b corresponding to the circumferential direction, and reach a position where they are engaged with each other in the axial direction. The middle pin 33 and the bolt cover 32 are integrally coupled by the engagement of the plurality of portions of the claws 33b and the claw receiving portion 37b in the circumferential direction. The middle pin 33 has an outer circumference including the tampon support portion 33a, the locking claw 33b, and the inner side of the locking claw 33b in the circumferential direction with the gap 33c as compared with the self 154665.doc 201144169 The abutment wall 33cl on the cap side. The abutting wall 33d# is axially abutted against the cap 32 in a state where the middle pin 33 is fastened to the cap 33. By this abutment, the middle pin 33 is positioned so as not to be displaced toward the axial cap side with respect to the cap 32. Further, between the detent pawl 33b and the bolt cover, an axial gap which is useful to allow the inclination of the detent pawl 33b is secured. The catching claws 33b are arranged in a pair in the radial direction of the thread. Therefore, by sandwiching the two portions of the locking claws 33b with the fingers, it is possible to easily press all the locking claws 33b and to forcibly overwhelm them in the oblique direction described above, thereby releasing the fastening. After it is released, the middle pin 33 can be separated from the cap 32 in the axial direction. The circumferential positioning between the middle pin 33 and the bolt cover 32 originates from the regulatory wall 37 formed on the circumferential sides of the claw receiving portion 37b (; is engaged with the circumferential direction of the locking claw 33b. The heat insulating chamber is formed in a circumferential shape. 5 or the inner and outer circumferences of the container, and the middle bolt 33 and the bolt cover 32 are also integrally provided on the inner and outer circumferences of the circumference. Since the circumferential positioning of each of the fastening claws 33b and the regulation wall 37c is obtained, even if The other circumferential positioning structure is disposed between the middle pin 33 and the bolt cover 32, and the middle pin 33 is also prohibited from rotating in the circumferential direction with respect to the bolt cover 32. As shown in Fig. 1 and Fig. 5, the cap cap 4 has The tubular portion 41 inserted into the inner circumference of the intermediate pin 33 and the cap packing 42 fitted to the outer periphery of the tubular portion 4丨. The cap packing 42 seals the inner circumference of the middle pin 33 and the tubular portion 41. Between the outer circumferences, the top surface of the cap cap 4 is formed in a plane orthogonal to the axial direction. In order to eliminate the formation of the wall portion 43 by the top surface of the cap cap 4 by providing the claw receiving portion 37b of the cap 32 Or it is necessary to bulge integrally toward the outside in the axial direction, so that the claw receiving portion 37b is axially opposed to the abutting position of the abutting wall 33d and the bolt cover 32. The plug cap is placed in a concave manner. 154665.doc •12· 201144169 The cap cap 4 can be assembled from the axial cap to the plug body in a state in which the cap 32 and the middle pin 33 are combined as described above to assemble the plug body 3. 3. The fixing force of the yoke body 3 of the tying cap 4 is derived from the adhesion between the cap filling member 42 and the inner circumference of the middle pin 33. The hood cap 4 covering the recessed space of the middle pin 33 The cylindrical portion 41, the cap packing member 42 and the top surface forming wall 43, and the middle pin 3 3 form the heat insulating chamber 5. The capacity of the heat insulating chamber 5 is obtained for the recessed depth of the middle pin 33, and compared with the packing member. The sealing position (minimum inner diameter portion Ua) of 34 is not low, and the deepest portion of the bottom surface of the heat insulating chamber $ is formed in the recessed bottom surface of the middle cymbal 33, and the axial position is compared with the sealing position of the packing member 34. The cap side is formed lower than the thread start end on the most axial cap surface side of the threaded portion 31. Also, in order to obtain the capacity of the heat insulating chamber 5, it is insulated in the top surface forming wall 43. The portion of the ceiling of the chamber 5 is formed to be relatively thinner in the axial direction than the bolt cover 32. Because of the sealing of the cap packing member 42, even The retaining claws 33b are formed by the gaps 33c of the middle bolts 33, and there is no need to worry about water immersion from the air gaps 33c toward the heat insulating chamber 5. Further, the water droplets attached to the cleaning or the ingestion of the beverage are on the side of the cap 4 as compared with the stuffing member 34. The attached residual droplets may reach from the gap 33c to between the top surface forming wall 43 of the cap cap 4 and the cap 32. To this end, the outer circumference and the top surface of the tubular portion 41 of the cap cap 4 form the wall 43 and the plug. The gap of the cover 32 is ensured throughout the entire circumference and the outside. Therefore, the water droplets or the like can be discharged to the outside by appropriately shaking the container port plug. The detachable cap cap 4 can be provided on the inspection body 3 The inclination restricting portion 44 is inserted from the axial direction to allow the inclination of the aforementioned detent pawl 33b. The inclination restricting portion 44 of the tampons cover 4 is attached to the plug body 3 to restrict the inclination of the detent pawl 33b to a range in which the claw receiving portion 37b cannot be detached from the claw receiving portion 37b 154665.doc • 13- 201144169. Therefore, even if the middle pin 3 3 is forcibly inclined with respect to the axial direction toward the side corresponding to the inclination direction of the buckle claw 3 3 b, and the buckle claw 3 3 b is crimped to the claw receiving portion 37b ', the cap can be utilized. The cover 4 prevents the locking claws 33b from coming out of the claw receiving portion 37b. Specifically, δ, the inclination restricting portion 44 is provided by the tubular portion 41 which is the inner side falling portion of the middle pin 33. The inclination restricting portion 44 of the tubular portion 41 can restrict the inclination of the locking claw 33b from the inner side of the middle pin 33. By the use of the tubular portion 41, the wall surface structure of the cap cap 4 can be prevented from being complicated as compared with the case where the dedicated tilt restricting portion is protruded from the tubular portion 41. Further, the inclination restricting portion is projected on the outer circumference of the tubular portion 41 in the radial direction of the thread. Thus, the tilt restricting portion 44 is partially protruded like a rib only to avoid useless processing. The tilt restricting portion 44 is provided so as to be able to protrude over the entire circumference of the outer circumference in order to eliminate, for example, the circumferential position of the locking claws 331. Since the inclination restricting portion 44 is provided in the circumferential direction portion, in order to prevent the inclination restricting portion 44 from coming out of the range of the support detent pawl 33b in the circumferential direction, the circumferential positioning between the cap cap 4 and the cap cover 32 is required. This positioning is caused by the circumferential forming wall 43 of the cap* being circumferentially engaged with the second regulating wall 37d of the cap 32 shown in Fig. 4. Since the second regulating wall 37d is formed by the same mold together with the claw receiving portion 37b and the like, it is partially recessed toward the axial packing side. As shown in Fig. 3, similarly to the bolt cover 32 and the middle inspection 33, the cylinder portion of the cap cover is required to be integrally provided on the inner and outer circumferences of the circumference. Since the profit is available: the second gauge wall 37d of FIG. 4®5 and the circumferential surface of the top surface forming wall G are positioned 'so as shown in FIGS. i and 3, even in the bolt cover 32 and the cap 4 The other circumferential configuration is not provided, and the cap 4 can also be rotated relative to the inspection 154665.doc -14. 201144169 cover 32 in the circumferential direction. The other middle pin 33 is provided as one member by injection molding. The middle plug 33 month color can be separated from the bolt cover 3 2 by one part, but if the middle plug is combined with a plurality of members, the number of parts is increased, and the cleaning of the joint gap is troublesome. In the first embodiment described above, when the middle pin 33 is separated from the bolt cover 32, the outer circumference of the plug 33 in the stuffing member support portion 33a to which the packing member 34 is attached is included, and the outer peripheral portion is on the axial side of the cap portion. The buckle claw 33b and the abutting wall 33d are separated from the bolt cover 32. Therefore, as shown in Fig. 1, the inner circumference and the lower surface of the bolt cover 32 which form the gap between the inner circumference of the bolt cover 32 and the outer circumference of the middle bolt 33 will be Since the middle pin 33 disappears, it is large. Therefore, it is easy to directly clean the inner circumference and the lower surface of the cap 32. As described above, the first embodiment can well maintain the cleanliness in the gap between the inner circumference of the cap cover 32 and the outer circumference of the middle pin 33, and the plug can be prevented from obstructing other members from the separation. The tampon support portion 33a is simply snapped or detached therefrom. Since the threaded portion 3 of the container mouth plug is provided on the inner circumference of the bolt cover 32, the stuffing member support portion 33a is provided in the outer circumference of the middle pin 33 from the thread portion facing the thread portion 31 in the radial direction. The sealing position of the packing member 34 can be placed on the side of the cap 4 so that the capacity can be made larger in the axial direction in the container casing. Even if the same capacity is ensured, the container i can be miniaturized. Also, in the container a of the package a-heavy heat container, the minimum inner diameter portion 11a of the inner container 11 is provided in such a manner as to exist on the side of the outer portion of the outer tube 12 closer to the side of the axial cap cap 4. Therefore, it is not necessary to lengthen the outer container 12 in the axial direction, so that the minimum inner diameter portion 内容a of the inner container can be close to the side of the cap cap 4 154665.doc •15·201144169, and the capacity of the inner container u can be ensured. Large in the axial direction. Therefore, since the bottom of the inner container u can be raised even if the same capacity is secured, the container 1 can be miniaturized. The second embodiment will be described with reference to Figs. 6 to 8 . In the following, the differences from the first embodiment will be mainly described, and the same constituent elements will be designated by the same names, and the description of the overlapping items will be omitted. As shown in the figure, the second embodiment can omit the decorative panel or the like, and the bolt cover 6 is composed of one part. The bolt cover 61 may have a second inner peripheral wall extending from the inner peripheral edge of the upper surface portion toward the axial packing side instead of the pressing member. Further, the middle pin 62 and the bolt cover 61 are fast-released. The cylindrical portion of the cap cap 63 is axially abutted with the wall portion forming the inner and outer circumferences of the plug to form an insulating chamber' which is not inserted into the inner side of the inner plug 62. Therefore, the heat insulating chamber can be increased in capacity, and the second inner peripheral wall of the cap 61 and the tubular portion of the cap cap 63 are sealed by the cap packing. A quick snap groove 64 is provided on the outer circumference of the middle pin 62. The quick card claw 65 is protruded from the second inner peripheral wall toward the axial packing side at a plurality of circumferential portions of the bolt cover 61. As shown in Fig. 8 (4) and Fig. 8 (b), if the cap 63 is attached to the plug body after the quick snap-off, the plug cap 63 can be blocked as shown in Fig. 8(e). The portion 66 is inserted into the recess from the insertion opening of the quick snap-off material in the axial direction. By the clogging portion 66, the displacement to the canceling rotation side of the quick ejector claw 65 can be surely prevented. The above embodiments are applied to a portable beverage container.
