201130433 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種用以將從香氣產生源所釋出之香氣 與空氣一同吸取之香氣吸管。 【先前技術】 此種香氣吸管係揭示於例如專利文獻1。此專利文獻1 之無煙煙草係具備管狀之管體（pipe body)，而此管體係具 有以可卸除方式插入於管體的一端内之吸嘴 (mouthpiece)，且在管體之内部收容有香氣產生匣 (cartridge)。在此香氣產生匣内係充填有例如煙絲，而在 此煙絲係添加有所希望之香料。 依據上述之無煙煙草，使用者係可透過吸嘴吸取，藉 此獲得類似吸煙的感覺。詳而言之，由於在香氣產生匣内 充滿了煙絲及從香料揮發的香氣成分，因此使用者可吸取 含有香氣成分之空氣，而品嘗享受香氣成分。 另一方面，為了使上述香氣產生匣容易更換，可考慮 將專利文獻2所揭示之煙草吸煙用導管之更換裝置應用於 專利文獻1之無煙煙草。此更換裝置係包含：環形滑塊 (slide)，可在管體之外周面上朝管體之軸線方向及周方向 滑動；及卡扣突起與卡扣溝，以彼此可分離之方式結合該 滑塊與管體内之匣盒。 依據此種更換裝置，當滑塊在管體上朝軸線方向滑動 時，滑塊會從管體拉出匣盒之端部。在此狀態下，只要滑 塊朝管體之周方向滑動，卡合突起與卡扣溝之結合即放 4 321853 201130433 開，之後，使滑塊恢復原來位置，藉此使！盒之端部從管 體露出。因此，使用者可把持匣盒之露出端部，而將匣盒 從管體完全拔出。 再者，專利文獻1之無煙煙草亦可具備覆蓋吸嘴之蓋 子（cap)，而此蓋子之一例係揭示於例如專利文獻3。 [先前技術文獻] [專利文獻1]日本特開平2-2331號公報 [專利文獻2]曰本實公昭53-9509號公報 [專利文獻3]日本實開昭63—188039號公報 【發明内容】 [發明所欲解決之課題] 將專利文獻2之更換裝置應用於專利文獻丨之無煙煙 草時，亦由於從管體將香氣產生匣完全拔出之際，香氣產 生匣處於自由的狀態，因此依據管體之姿勢，在使用者握 持香氣產生匣之前，香氣產生匣會掉入管體内，或從管體 掉出，而無法保證香氣產生匣的更換確實且穩定。 此外，藉由卡合突起及卡合溝構成之結合結構，無法 完全消除香氣產生匣相對於滑塊的晃動，而無法將香氣產 生匣穩定地保持在管體内。 再者，在將香氣產生匣拔出時，使用者必須直接握持 香氣產生匣。 =發明之目的係在提供一種香氣吸管，可將香氣產生 度穩定地保持在管體内，並且使时不需直接握持香氣產 生1^ ’即可從管體拔出香氣產生ϋ，再者，更換香氣產生 5 321853 201130433 匣時，可維持吸嘴的衛生。 [解決課題之手段] 上述之目的係藉由本發明之香氣吸管而達成，此香氣 吸管係具備：管體，作成管形，且具有開口狀之前端及基 端；筒狀香氣產生匣，以可拉出之方式收容於該管體内， 並在内部充填有使香氣成分揮發之香氣產生材料，且可容 許空氣從管體之前端側朝向基端側流通；中空吸嘴，以可 分離之方式結合於定位於管體基端側之香氣產生匣端部， 且具有從管體之基端突出之突出部分及定位於管體内之前 端部；以及結合裝置，以可分離之方式結合管體之基端與 吸嘴之前端部，且具有：結合位置，在吸嘴前端部從管體 基端冒出之方向以預定之彈推力將吸嘴相對於管體彈性地 推壓，而將管體及吸嘴彼此結合；與放開位置，使吸嘴與 彈推力抵抗而壓入於管體内，之後，於吸嘴相對於管體旋 轉時，容許吸嘴之前端部從管體拔出。 較佳為，香氣吸管復具備：蓋，具有開口端，且以可 卸除之方式覆蓋於吸嘴之突出部分；及卡合裝置，蓋覆蓋 於吸嘴時，係使蓋及吸嘴朝蓋之周方向彼此卡合。具體而 言，卡合裝置係包括複數個肋（rib)，該等肋係從蓋之内面 突出，用以夾入吸嘴之端。 另一方面，結合裝置係包括：凸緣（flange)，形成於 吸嘴之外周面；周溝，形成於管體之基端之内周面，且在 前述基端朝吸嘴冒出方向開口，並在管體之内周面提供朝 向基端侧之段差面；彈性構件，夾入於凸緣與段差面之間， 6 321853 201130433 用以產生前述彈推力；引導溝，形成於管體之内周面，且 在段差面開口，且具有：軸方向部分，從段差面朝前述管 體之軸線方向延伸；與周方向部分，從該軸方向部分之端 朝管體之周方向延伸；以及卡扣爪，設於吸嘴之前端部之 外周面，且位於引導溝之周方向部分内並且吸嘴受到彈推 力，藉此與用以決定結合位置之引導溝之周方向部分之溝 壁抵接。 較佳為，在彈性構件係可使用包圍吸嘴之外周面之彈 性環，更具體而言，係可使用0環，而此0環之剖面形狀 並不限定於圓形。 依據上述之香氣吸管，於結合裝置位於結合位置時， 吸嘴之卡合爪係受到彈性構件之彈推力，而處於推壓於引 導溝之周方向部分之溝壁之狀態。因此，吸嘴係穩定地結 合於管體。 香氣吸管具備蓋時，在使用香氣吸管之前，使用者先 將蓋從吸嘴筆直地拉出卸除，以使吸嘴露出。此時，由於 結合裝置位於吸嘴結合於管體之結合位置，因此吸嘴不會 與香氣產生匣一同從管體拔出。 之後，使用者可銜著露出之吸嘴而抽吸。在此之抽吸， 係將在香氣產生匣内從香氣產生材料所揮發之香氣成分隨 空氣一同導入於使用者之口腔内，結果，使用者可享受香 氣成分。 當香氣產生匣達到使用限度，而產生需將香氣產生匣 更換為新的香氣產生匣時，使用者在握持蓋之狀態、或直 7 321853 201130433 接握持吸嘴之狀態，與前述彈推力抵抗暫時將吸嘴朝向管 體内壓入。在此之壓入係從引導溝之前述溝壁放開卡扣 爪。在此狀態下，使用者只要使吸嘴朝管體之周方向旋轉， 卡扣爪就從引導溝之周方向部分朝軸方向部分移動，而結 合裝置則從結合位置定位於放開位置。因此，在此放開位 置，使用者只要直接或透過蓋將吸嘴朝冒出方向拉動，卡 扣爪就一面沿著引導溝之軸方向部分移動一面從引導溝掉 出。亦即，吸嘴不會被卡扣爪阻礙，而與香氣產生匣一同 從管體拉出，結果，香氣產生匣即從管體完全拔出。 所拔出之香氣產生匣係從吸嘴卸除，且於吸嘴安裝新 的香氣產生匣。之後，使用者係直接或透過蓋握持吸嘴， 且將新的香氣產生匣插入於管體内，並將吸嘴之前端部插 入於管體内。此種吸嘴之插入，係一面使彈性構件，亦即 彈性環或〇環壓縮於吸嘴之凸緣與管體之段差面之間，一 面使卡扣爪沿著引導溝之軸方向部分移動，藉此而使結合 裝置定位於放開位置。 在此狀態下，使用者只要將吸嘴朝管體之周方向旋 轉，卡扣爪就沿著引導溝之周方向部分移動。之後，當使 用者放開吸嘴之壓入時，吸嘴即受到彈性環或〇環之彈推 力，而使卡扣爪抵接於引導溝之周方向部分之溝壁。在此 時點，結合裝置係定位於結合位置，然後完成香氣產生匣 之更換。 [發明之功效] 依據本發明之香氣吸管，結合裝置位於結合位置時， 8 321853 201130433 由於吸嘴係彈性結合於管體，因此吸嘴不會相對於管體晃 動’而可保證吸嘴對於管體的穩定結合。 另方面，在更換香氣產生s時，使用者係可在握持 吸嗅之狀態下，將香氣產生匣與吸嘴一同從管體拔出，而 可容易進行香氣產生匣的拔出。此時，只要蓋子覆蓋於吸 嘴，則使用者手指不會直接接觸吸嘴，而可衛生地進行香 氣產生匣的更換。 本發明之其他特徵及優點，係可從參照所附圖式所說 明之後述之最佳形態而明瞭。 【實施方式】 參照第1圖及第2圖，一實施例之香氣吸管係具備管 形之官體10,而此管體1〇係由合成樹脂所形成，具有開 口狀之兩端。此實施例之情形中，從第3圖可得知，管體 10之橫剖面不具有圓形輪廓，而是具有類似正方形之形 狀。詳而言之，橫剖面之輪廓係由類似於平坦面之4個大 的圓弧面10a、及連接此等圓弧面1〇&之4個小的圓弧面 l〇b所形成，而如第！圖所示，此等圓弧面1〇b係在管體 10之外周面形成4個條帶。此等條帶丨丨係朝 管體10之軸線方向延伸，而且，繞著管體1〇之轴線隔開 9 0之間隔配置。 如第2圖所示，在管體1〇内係同心地收容有圓筒狀的 煙草匣12作為香氣產生匣，而煙草匣12係可於管體1〇内 朝軸線方向及周方向移動。 煙草£ 12係具備管子14，而在此管子14之兩端係分 321853 9 201130433 別插入有終端件（end piece)16、18。此等終端件16、18 係呈中空套筒（sleeve)形狀，包含從管子14之前端及基端 突出之突出端16a、18a。此等突出端16a、18a係呈具階 差形狀，具有與管子14對應側之端面相接觸之凸緣狀大徑 部、及從該大徑部延伸之小徑部。大徑部之外徑係與管子 14之外徑大致相等，而小徑部之外徑係較管子14之外徑 小。 再者，從管體10之前端内周面起一體突出有環狀突起 20，而此環狀突起20係在管體10之前端提供插入孔22。 此插入孔22之内徑，係較突出端16a之小徑部之外徑稍 大，因此，如第2圖所示，突出端16a之小徑部係以可拔 出之方式插入於插入孔22内。在此，應注意者為，在突出 端16a之大徑部與環狀突起20之間已確保了預定的間隙 (gap)G 。 另外，上述之管子14及終端件16、18雖係由合成樹 脂所形成，惟管子14係以透明或半透明者為較佳。 再者，在管子14内係與終端件16、18分別鄰接配置 有圓筒狀過濾器（；^1七61')24、26，此等過濾器24係包含醋 酸鹽（acetate)纖維束、及包覆此纖維束之包材。在管子 14内係於過濾器24、26間形成有充填室，而在此充填室 係以預定密度充填有煙草材料T。香煙材料係包含煙絲、 及添加於此煙絲之香料。 在管子14之内周面係一體形成有複數個肋28。此等 肋28係在過濾器24、26間朝管子14之轴線方向延伸，從 10 321853 弟4圖可得知，在管子 28係既維持管子 之周方向隔著間隔配置。此種肋 4 t強声， 此外，亦有助於作為過璩二又有利於管子14之薄壁化， 在終端件18之突24 26用之擋止件（st〇pper)。 保有預定距#，而:1山端18a*管體10 <基端之間係確 連接有中空之二出端183之小徑部以可卸除之方式 詳而言之，從第2圖可得知，ώ 樹剛成，且從終端…丄== 形大控部30a、錐⑴㈣部3〇b及扁平之桿如心部3〇c。 桿部30c係在其邊端具有矩形拱出部3〇d，而此棋出部_ 係較桿部3〇C大’且具有彼此平行之一對平坦面版"及 嘴30之大徑部30a係以可拉出之方式插入於管體1〇之基 端内’另-方面，突出端18a之小徑部係以可分離之方式 插入於吸嘴30之大徑部30a内。結果，終端件18之凸緣 係處在炎入於吸嘴30之大徑部30a與管子14之間之狀 態。亦即，吸嘴30之大徑部30a係具有較管體1 〇之内徑 稍小之外徑，而且，具有較突出端18a之小徑部之外經稍 大之内徑。 大徑部3Qa之一部分、錐部30b及桿部3〇c係從管體 之基端突出’而此種吸嘴30之突出部位，係由合成樹 脂之蓋子32所覆蓋。此蓋子32係呈中空筒形，具有開D 端及封閉端。 更詳而言之，蓋子32之開口端係具有較吸嘴30之大 徑部30a之外徑稍大之内徑。因此，蓋子32係在其内部從 321853 11 201130433 開口端側接受吸嘴30之突出部位，使開口端從外側嵌合於 大徑部30a，藉此而以可分離之方式結合於吸嘴3〇。 蓋子32之橫剖面之輪廓係具有與前述之管體1〇之橫 剖面之輪廓相同尺寸及形狀，因此，如第丨圖所示，蓋子 32係在其外周面具有相當於前述條帶u之4個條帶u。 蓋子32之開口端係在其内面具有複數個卡合凹部 34而此等卡合凹部34係在蓋子32之周方向隔著等間隔 配置。另一方面，吸嘴30之大徑部3〇a係在其外周面具有 相對於各卡合凹部34之卡合突起36，而此等卡合突起祁 亦在吸嘴30之周方向隔著等間隔配置。因此，蓋子犯覆 蓋於吸嘴30之突出部位，而嵌入與卡合凹部％對應之卡 合突起36時，蓋子32係以可分離之方式結合於吸嘴3〇。 此種卡合凹部34與卡合突起36之卡合，係用以防止蓋子 32不預期地從吸嘴30脫落，而且，供使用者掌握俾使蓋 子32正常覆蓋於吸嘴3〇。 再者’在蓋子32之内周面係於蓋子32之封閉端侧形 成有4個肋38。此等肋38係朝蓋子32之軸方向延伸而且 在蓋子32之周方向隔著間隔配置。 詳而言之，從第5圖可得知，蓋子32正常覆蓋於吸嘴 30時，4個肋38係夾緊吸嘴30之拱出部3〇d。具體而言， 2個肋38係與棋出部3〇d之一方平坦面，接觸，剩下°的 2個肋38則與拱出部30d之另一方平坦面3〇e接觸。此外， 第5圖係顯示4個肋38不僅可以實線所示之第}姿勢夾緊 拱出部30d，尚且從第！姿勢至拱出部_，亦即，在吸嘴 321853 201130433 30相對旋轉90°左右之2點鏈線所示之第2姿勢，亦可夾 緊拱出部30d。 . 藉由上述之肋38夾緊拱出部30d，不論拱出部30d之 姿勢如何，均將蓋子32及吸嘴30在周方向上彼此結合， 另一方面，從第1圖可得知，使蓋子32之條帶13與對應 之管體10之條帶11彼此整合在同一線上。亦即，蓋子32 正常覆蓋於吸嘴30時，使蓋子32之各條帶13在管體10 及蓋子32之周方向上定位於管體10的對應條帶11。 另一方面，吸嘴30之大徑部30a不僅結合於煙草匣 12之終端件18，尚且亦藉由結合裝置40以可分離之方式 結合於管體10之基端。 結合裝置40係如第6圖及第7圖所詳示，以下說明結 合裝置40。 如第6圖（A)所示，管體10之基端係在其内周面具有 周溝42。此周溝42係於管體10之基端面開口，另一方面 在管體10之内周面形成環狀擋止面44。 另一方面，在吸嘴30之大徑部30a係在其外周面一體 形成有凸緣46，而此凸緣46係定位於較卡合突起36靠管 體10之基端側。蓋子32正常覆蓋於吸嘴.30時，在蓋子 32之端面抵接於凸緣46之狀態下，前述之卡合突起36係 成為可嵌入於卡合凹部34。亦即，凸緣46係發揮作為對 蓋子32之擋止件之功能，用以決定蓋子32相對於吸嘴30 之軸方向位置。另外，蓋子32正常覆蓋時，從第2圖可得 知，應注意在蓋子32之封閉端之内面與吸嘴30端之間係 13 321853 201130433 已確保了預定的間隔。 此外’凸緣46係、具有較周溝42之内徑稍小之外徑， 因此，從第6圖⑴可得知，凸緣46係處於局部進入周溝 42内之狀態。 再者，在吸嘴30之大徑部3〇a外周面係安裝有環狀彈 ’㈣㈣0環48。此〇環48係夹入於卡合突起 36相反侧之凸緣46之端面與周溝犯之擋止面&之間。 詳而言之，0環48係具有較周溝42之内徑為小之外徑， 並且處於自由狀態時之寬度Dd係例如與周溝42 同。因此，如前所述，凸緣46局部進入周溝42内時^ 〇 環48係處於在凸緣46與擋止面44之間朝吸嘴3〇之軸線 方向壓縮之狀態，此時之〇環48之寬度Di從第6圖（幻可 得知係較前述寬度D。小。 0環48處於上述之壓縮狀態時，〇環48係使吸嘴3〇 朝從管體10之基端脫出之方向彈推吸嘴3〇，惟在此之吸 嘴30之脫出，係藉由吸嘴30卡扣於管體1〇之方式來阻止。 詳而言之，在吸嘴30之大徑部30a係於其外周面具有 1個以上卡扣爪50，而此實施例之情形係具有2個卡扣爪 50。此等卡扣爪50係在吸嘴30之直徑方向彼此分離，且 定位於較0環48偏靠大徑部30a之前端側。 另一方面，在管體10之内周面係形成有2個引導溝 52 ’而此等引導溝52係在管體1〇之直徑方向彼此分離， 用以接受對應之卡扣爪50。各引導溝52係具有朝向管體 10之前端側之承座，而卡扣爪50係以預定的推力抵接於 321853 14 201130433 此承座。在此之推力係藉由前述之吸嘴30之彈推力，亦即 因0環48之壓縮所產生之0環48恢復力所獲得。 如上所述，只要卡扣爪50推壓於引導溝52之承座， 則吸嘴30即確實結合於管體10之基端，而吸嘴30不會與 蓋子32 —同從管體10脫落。 茲詳述有關上述引導溝52之形狀如下。 從第6圖（B)及第7圖可得知，引導溝52係具有：朝 管體10之軸線方向延伸而且在前述之周溝42之擋止面44 開口之軸方向部分52a、及連接於此軸方向部分52a之内 端之周方向部分52b。此周方向部分52b係從軸方向部分 52a之内端在管體10之周方向延伸一預定長度。 較佳者為，形成軸方向部分52a之2個溝壁之中，至 少與周方向部分52b之端面對向之溝壁，不與管體10之軸 線平行，而係在周方向部分52b之延伸方向傾斜。 此外，形成周方向部分52b之2個溝壁之中，位於擋 止面44側之溝壁，係設有前述之承座。詳而言之，在此溝 壁係形成有凹部，而此凹部係與周方向部分52b之端面共 同作用，而形成容許卡扣爪50之嵌入之凹狀爪座54。因 此，卡扣爪50欲入於爪座54時（結合裝置.40之結合位 置），爪座54係從三方侷限卡扣爪50，用以阻止卡扣爪50 朝從管體10脫出之方向移動及卡扣爪5 0朝管體10周方向 之移動。結果，不僅阻止吸嘴30在管體10之軸線方向之 晃動，亦同時阻止在管體10之周方向之晃動。 使用者使用上述實施例之香氣吸管時，首先，使用者 15 321853 201130433 係朝吸嘴30之軸線方向將蓋子32從吸嘴30筆直地拉開， 並解開蓋子32之卡合凹部34與吸嘴30之卡合突起36間 的卡合，之後，若進一步繼續拉開蓋子32，則如第8圖所 示，蓋子32會從吸嘴30卸除，而使吸嘴3〇露出。 另外’蓋子32從吸嘴30拉開時，由於吸嘴之卡4 爪50係後入於引導溝52之爪座54的狀態，亦即對管體 10卡合之狀態，因此吸嘴30不會與煙草匣12 一同從管體 10脫出。 在此狀態下，使用者係水平地銜住吸嘴3〇之拱出部 30d，且透過此吸嘴30抽吸，藉此即可享受煙草匣12内之 煙絲原本的風味及味覺，以及添加於煙絲之香料的香味。 詳而言之，由於煙草匣12内係充滿煙絲及從香料揮發之香 氣成分，因此使用者之抽吸，會產生從管體之前端通過 煙草匣12及吸嘴30到達使用者口腔内之空氣流。因此，D 香氣成分與此空氣流一同引導至使用者之口腔内，結果， 使用者不需點燃煙絲即可享受香氣成分。 此外，抽吸時，使用者係將管體1〇之類似之上下圓弧 面10a夾於食減中指之間，因此可穩定職持管體1〇。 另一方面，煙草匿12達到使用限度時，如第9圖所示， 使用者可將煙草g 12與蓋子32及吸嘴3Q —同從管體1〇 卸除。 關於此處煙草E 12之卸除，兹參照第1〇圖詳述如下。 首先，香氣吸管處於第丨圖所示之非使用狀態時 用者係將蓋子32朝第1()圖（A)t之箭頭F之方向，亦即朝 321853 201130433 管體ίο推入。此時，蓋子3? 2之刖鸲係與吸嘴3〇之凸緣 吸嘴30之刖端係處於與煙草匣12之終端 件18之凸緣46抵接之狀態，因此蓋子32之推人會使吸Ϊ 3及煙草S12朝管㈣之前端側往其概方向移動。^ 外’此處之煙草匣12之移動_ 動如則所返會由於在煙草匣 中之終端件16之凸緣與管體1G之環狀突起Μ之間確 保有間隙G(參照第2圖）而受到容許。 上述之吸嘴3G之移動，如第1G圖⑴所示，會使卡扣 爪50從引導溝52之爪座54拔出，另—方面，使吸嘴3〇 之凸緣46與管體10之擋止面44間之〇環48更為魔缩， 而使0環48之寬度進一步從Dl減少至D2。 =後，只要使用者—面維持上述之蓋子&之推入，一 面使蓋子32朝第1〇圖⑻中之箭頭c方向（由第7圖觀看 為逆時針方向）繞著其軸線旋轉，即可如前所述地，蓋子 32及吸嘴30在周方向上處於藉由前述之肋一體結合 之狀態，因此吸嘴30及煙草g 12亦與蓋子％ 一同旋轉。 在此之吸嘴30之旋轉，會使卡扣爪5〇從引導溝之周方 向部分52b移動至軸方向部分52a(結合裝置4〇之放開 置）。 在此狀態下，只要使用者放開對蓋子32之推壓，處於 壓縮狀態之0環48之恢復力就將吸嘴3〇朝從管體1〇彈出 之方向推回。因此，〇環48之寬度從A回到至Dd，另一方 面，卡扣爪5G係沿著引導溝52之軸方向部分52a，移動 到引導溝52之開口端側。 321853 17 201130433 從此狀態，使用者藉由一面握持蓋子32 —面朝第10 圖（C)中箭頭R之方向拉回蓋子32，藉此可使卡扣爪50從 引導溝52拉出，且可從管體10與吸嘴30 —同拉出煙草匣 12。結果，如第9圖所示，煙草匣12很容易從管體10卸 除。 之後，煙草匣12從吸嘴30分離，而新的煙草匣12之 終端件18插入於吸嘴30，藉此而使新的煙草匣12結合於 吸嘴30。 使用者係在握持蓋子32之狀態下，將新的煙草匣12 插入於管體10内，且在使吸嘴30之卡扣爪50定位於管體 10的對應引導溝52之開口端之狀態下（參照第7圖），將 吸嘴30之大徑部30a推入於管體10之基端内，且使卡扣 爪50進入引導溝52之軸方向部分52a内。此時，吸嘴30 之0環48係夾於吸嘴30之凸緣46與管體10之擋止面44 之間，因此伴隨著0環48之壓縮，卡扣爪50即定位於引 導溝52之周方向部分52b(參照第10圖（B))。 之後，只要在使用者維持蓋子32及吸嘴30之推入狀 態下，使蓋子32朝順時針方向旋轉，蓋子32即如前所述 在周方向上與吸嘴30 —體結合，因此吸嘴30及煙草匣12 亦朝順時針方向旋轉。因此，卡扣爪5 0係與周方向部分 52b之端面抵接（參照第10圖（A))，在此狀態下，使用者 將蓋子32及吸嘴30之推力放開時，如第6圖（B)所示，卡 扣爪50即再度嵌入引導溝52之爪座54，在此時點，即完 成煙草匣12之更換。此時，蓋子32之條帶13當然對準於 18 321853 201130433 管體10所對應之條帶11相同線上。 另外，煙草匣12之更換，亦可於將新的煙草匣12插 入於管體10内之後，將保持於蓋子32之吸嘴30插入於管 體10内。 關於此種煙草匣12之更換，由於吸嘴30係藉由蓋子 32所保持，因此使用者之手指不會直接接觸吸嘴30。因 此，使用者可衛生地進行煙草匣12之更換。 另一方面，亦可不使用蓋子32而進行煙草匣12之更 換。亦即，此時，使用者係在直接握持吸嘴30之狀態下，:

Description of the Invention: [Technical Field] The present invention relates to an aroma pipette for extracting aroma released from a source of aroma with air. [Prior Art] Such a fragrance pipette is disclosed, for example, in Patent Document 1. The smokeless tobacco of Patent Document 1 has a tubular pipe body having a mouthpiece that is removably inserted into one end of the pipe body, and is housed inside the pipe body. The aroma produces a cartridge. Here, the aroma is produced by filling the interior with, for example, cut tobacco, and the tobacco is added with a desired fragrance. According to the above-mentioned smokeless tobacco, the user can suck through the nozzle, thereby obtaining a feeling similar to smoking. In detail, since the aroma is filled with the tobacco and the aroma component volatilized from the fragrance, the user can absorb the air containing the aroma component and taste the aroma component. On the other hand, in order to make the above-described aroma generation easy to replace, it is conceivable to apply the tobacco smoking catheter replacement device disclosed in Patent Document 2 to the smokeless tobacco of Patent Document 1. The replacement device comprises: an annular slide which slides on the outer circumferential surface of the pipe body in the axial direction and the circumferential direction of the pipe body; and the snap protrusion and the buckle groove are coupled to each other in a detachable manner The box inside the block and the tube. According to this replacement device, when the slider slides on the tubular body in the axial direction, the slider pulls the end of the cassette from the tubular body. In this state, as long as the slider slides in the circumferential direction of the pipe body, the combination of the engaging projection and the snap groove is opened, and then the slider is returned to the original position, thereby making it! The end of the box is exposed from the tube. Therefore, the user can hold the exposed end of the cassette and completely remove the cassette from the tube. Further, the smokeless tobacco of Patent Document 1 may have a cap covering the nozzle, and an example of the cover is disclosed, for example, in Patent Document 3. [Patent Document 1] Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. [Problems to be Solved by the Invention] When the replacement device of Patent Document 2 is applied to the smokeless tobacco of the patent document, the aroma is generated in a free state because the aroma is completely removed from the tube body, and therefore In the posture of the tube body, before the user holds the aroma and generates a flaw, the aroma of the aroma will fall into the tube body or fall out of the tube body, and the replacement of the aroma is not guaranteed to be true and stable. Further, the combination of the engaging projection and the engaging groove does not completely eliminate the sloshing of the aroma generating ridge relative to the slider, and the aroma generation enthalpy cannot be stably held in the tubular body. Furthermore, when the aroma is generated, the user must directly hold the aroma to produce a flaw. The purpose of the invention is to provide an aroma suction pipe which can stably maintain the aroma generation degree in the tube body, and can be used to pull out the aroma from the tube body without causing a direct holding of the aroma. When the aroma is changed to produce 5 321853 201130433 可, the hygiene of the nozzle can be maintained. [Means for Solving the Problem] The above object is achieved by the aroma pipette of the present invention, the aroma pipette comprising: a tubular body formed in a tubular shape and having an open front end and a base end; the cylindrical aroma generates a crucible The pull-out method is housed in the tube body, and is filled with aroma generating material for volatilizing the aroma component, and allows air to flow from the front end side toward the proximal end side of the tube body; the hollow nozzle is separable The scent is coupled to the base end side of the tubular body to produce a ridge end, and has a protruding portion protruding from the base end of the tubular body and a front end portion positioned in the tubular body; and a coupling device for detachably joining the tubular body The base end and the front end of the nozzle have a joint position, and the nozzle is elastically urged relative to the tube body at a predetermined spring force in a direction in which the front end portion of the nozzle emerges from the base end of the tube body, and the tube is pressed The body and the nozzle are coupled to each other; and the release position is such that the nozzle and the spring force are pressed against the tube body, and then the nozzle is allowed to be pulled out from the tube body when the nozzle is rotated relative to the tube body. . Preferably, the aroma suction pipe is provided with: a cover having an open end and covering the protruding portion of the suction nozzle in a detachable manner; and a snapping device, the cover and the suction nozzle facing the cover when the cover covers the suction nozzle The circumferential directions are engaged with each other. Specifically, the engaging means includes a plurality of ribs projecting from the inner surface of the cover for clamping the end of the nozzle. In another aspect, the bonding device includes: a flange formed on the outer circumferential surface of the nozzle; a circumferential groove formed on the inner circumferential surface of the base end of the tubular body, and opening at the base end toward the suction nozzle And providing a step surface facing the base end side on the inner circumferential surface of the pipe body; the elastic member is sandwiched between the flange and the step surface, 6 321 853 201130433 is used to generate the aforementioned elastic thrust; the guiding groove is formed in the pipe body The inner peripheral surface is open at the step surface and has an axial direction portion extending from the step surface toward the axial direction of the tubular body; and a circumferential portion extending from the end of the axial direction portion toward the circumferential direction of the tubular body; The locking claw is disposed on the outer circumferential surface of the front end of the suction nozzle, and is located in the circumferential direction portion of the guiding groove, and the suction nozzle is subjected to the elastic thrust, thereby being offset from the groove wall of the circumferential direction portion of the guiding groove for determining the coupling position. Pick up. Preferably, in the elastic member, an elastic ring surrounding the outer peripheral surface of the nozzle can be used, and more specifically, a 0 ring can be used, and the sectional shape of the 0 ring is not limited to a circular shape. According to the aroma suction pipe described above, when the coupling device is at the coupling position, the engaging claw of the suction nozzle is subjected to the elastic force of the elastic member, and is in a state of being pressed against the groove wall of the circumferential portion of the guiding groove. Therefore, the nozzle is stably bonded to the tubular body. When the aroma pipette is provided with a lid, the user first pulls the lid out of the nozzle and removes it before using the aroma suction pipe to expose the nozzle. At this time, since the coupling device is located at the joint position where the suction nozzle is coupled to the tubular body, the suction nozzle is not pulled out from the tubular body together with the aroma generation. Thereafter, the user can draw with the exposed nozzle. In the suction, the aroma component volatilized from the aroma generating material in the aroma generating sputum is introduced into the oral cavity of the user together with the air, and as a result, the user can enjoy the aroma component. When the aroma is generated to reach the limit of use, and the aroma is generated to be replaced with a new aroma, the user holds the cover or the state of holding the nozzle, and resists the aforementioned thrust. Temporarily press the nozzle into the tube. Here, the press-in is released from the groove wall of the guide groove. In this state, the user only needs to rotate the suction nozzle in the circumferential direction of the tubular body, and the locking claw is partially moved in the axial direction from the circumferential direction portion of the guiding groove, and the bonding device is positioned in the releasing position from the coupling position. Therefore, at this release position, the user can pull the suction nozzle in the direction of the ejection directly or through the cover, and the locking claws are partially removed from the guide groove while moving along the axial direction of the guide groove. That is, the nozzle is not obstructed by the snap claws, and is pulled out from the tube together with the aroma generated, and as a result, the aroma is completely pulled out from the tube. The extracted aroma produces a tether that is removed from the nozzle and a new aroma is applied to the nozzle to create a flaw. Thereafter, the user holds the nozzle directly or through the cover, and inserts a new aroma generating cymbal into the tube body, and inserts the front end of the nozzle into the tube body. The insertion of the nozzle is such that the elastic member, that is, the elastic ring or the ankle ring, is compressed between the flange of the nozzle and the step surface of the tube body, and the locking claw is partially moved along the axial direction of the guiding groove. Thereby, the bonding device is positioned in the release position. In this state, the user simply rotates the suction nozzle toward the circumferential direction of the tubular body, and the snap claw moves partially along the circumferential direction of the guide groove. Thereafter, when the user releases the suction of the suction nozzle, the suction nozzle is biased by the elastic ring or the loop, and the snap claw abuts against the groove wall of the circumferential portion of the guide groove. At this point, the bonding device is positioned at the bonding position and then the aroma generation is replaced. [Effect of the Invention] According to the aroma suction pipe of the present invention, when the bonding device is located at the bonding position, 8 321853 201130433, since the nozzle is elastically coupled to the pipe body, the nozzle does not sway relative to the pipe body, and the nozzle can be secured to the pipe. Stable combination of body. On the other hand, when the aroma generation s is changed, the user can pull the aroma generation sputum out of the tube together with the suction nozzle while holding the smear, and the scent can be easily extracted. At this time, as long as the cover covers the nozzle, the user's finger does not directly contact the nozzle, and the aroma can be hygienically replaced. Other features and advantages of the invention will be apparent from the description and appended claims. [Embodiment] Referring to Figs. 1 and 2, an aroma pipette of an embodiment has a tubular body 10 which is formed of a synthetic resin and has open ends. In the case of this embodiment, as can be seen from Fig. 3, the cross section of the pipe body 10 does not have a circular profile but has a square-like shape. In detail, the profile of the cross section is formed by four large circular arc faces 10a similar to the flat faces, and four small circular arc faces l〇b connecting the arcuate faces 1〇& And as the first! As shown in the figure, the arcuate faces 1〇b form four strips on the outer peripheral surface of the pipe body 10. These strips are extended in the direction of the axis of the tubular body 10, and are arranged at intervals of 90 around the axis of the tubular body 1〇. As shown in Fig. 2, a cylindrical tobacco crucible 12 is concentrically accommodated in the tubular body 1 as an aroma generating crucible, and the tobacco crucible 12 is movable in the axial direction and the circumferential direction in the tubular body 1〇. The tobacco £12 series has a tube 14, and the ends of the tube 14 are 321853 9 201130433. End pieces 16, 18 are not inserted. The end pieces 16, 18 are in the shape of a hollow sleeve and include projecting ends 16a, 18a projecting from the front end and the base end of the tube 14. The projecting ends 16a and 18a have a stepped shape, and have a flange-shaped large diameter portion that comes into contact with the end surface on the corresponding side of the tube 14, and a small diameter portion that extends from the large diameter portion. The outer diameter of the large diameter portion is substantially equal to the outer diameter of the tube 14, and the outer diameter of the small diameter portion is smaller than the outer diameter of the tube 14. Further, an annular projection 20 is integrally protruded from the inner peripheral surface of the front end of the tubular body 10, and the annular projection 20 is provided with an insertion hole 22 at the front end of the tubular body 10. The inner diameter of the insertion hole 22 is slightly larger than the outer diameter of the small diameter portion of the protruding end 16a. Therefore, as shown in Fig. 2, the small diameter portion of the protruding end 16a is inserted into the insertion hole in an extractable manner. 22 inside. Here, it should be noted that a predetermined gap G is secured between the large diameter portion of the projecting end 16a and the annular projection 20. Further, although the above-mentioned tube 14 and terminal members 16, 18 are formed of a synthetic resin, it is preferable that the tube 14 is transparent or translucent. Further, in the tube 14, a cylindrical filter (;1 七7 61') 24, 26 is disposed adjacent to the end members 16, 18, respectively, and the filter 24 includes an acetate fiber bundle, And a package material covering the fiber bundle. A filling chamber is formed in the tube 14 between the filters 24, 26, and the filling chamber is filled with the tobacco material T at a predetermined density. The cigarette material comprises cut tobacco, and a flavor added to the cut tobacco. A plurality of ribs 28 are integrally formed on the inner circumference of the tube 14. These ribs 28 extend between the filters 24 and 26 in the axial direction of the tube 14. As can be seen from Fig. 10 321 853, the tube 28 is disposed at intervals in the circumferential direction of the tube. Such a rib 4 t is strong, and in addition, it also contributes to the thinning of the tube 14 as a pass and a stop for the end piece 18 of the end piece 18. Preserving the predetermined distance #, and: 1 mountain end 18a* pipe body 10 < the base end is connected to the small diameter end of the hollow end 183 is detachable, in detail, from the second figure It is known that the eucalyptus tree is just formed, and from the terminal ... 丄 == shape control portion 30a, cone (1) (four) portion 3 〇 b and flat rod such as the heart portion 3 〇 c. The rod portion 30c has a rectangular arch portion 3〇d at its side end, and the chess portion _ is larger than the rod portion 3〇C and has a large parallel to each other and a flat plate" The portion 30a is inserted into the base end of the tubular body 1A in a pull-out manner, and the small-diameter portion of the protruding end 18a is detachably inserted into the large-diameter portion 30a of the suction nozzle 30. As a result, the flange of the terminal member 18 is in a state of being inflamed between the large diameter portion 30a of the suction nozzle 30 and the tube 14. That is, the large diameter portion 30a of the suction nozzle 30 has an outer diameter slightly smaller than the inner diameter of the tubular body 1 ,, and has a slightly larger inner diameter than the small diameter portion of the protruding end 18a. One of the large diameter portions 3Qa, the tapered portion 30b, and the rod portion 3〇c protrude from the base end of the tubular body, and the protruding portion of the nozzle 30 is covered by the cover 32 of the synthetic resin. The cover 32 has a hollow cylindrical shape with an open D end and a closed end. More specifically, the open end of the cover 32 has an inner diameter slightly larger than the outer diameter of the large diameter portion 30a of the suction nozzle 30. Therefore, the cover 32 receives the protruding portion of the suction nozzle 30 from the open end side of 321853 11 201130433 in the inside thereof, and the open end is fitted to the large diameter portion 30a from the outside, thereby being detachably coupled to the suction nozzle 3〇. . The cross-sectional profile of the cover 32 has the same size and shape as the cross-section of the tubular body 1〇. Therefore, as shown in the figure, the cover 32 has an outer peripheral surface corresponding to the aforementioned strip u. 4 strips u. The open end of the cover 32 has a plurality of engaging recesses 34 on its inner surface, and the engaging recesses 34 are disposed at equal intervals in the circumferential direction of the cover 32. On the other hand, the large diameter portion 3A of the suction nozzle 30 has an engagement projection 36 with respect to each of the engagement recesses 34 on its outer circumferential surface, and the engagement projections are also interposed in the circumferential direction of the suction nozzle 30. Equally spaced configuration. Therefore, when the cover is covered by the protruding portion of the suction nozzle 30, and the engaging projection 36 corresponding to the engagement recess portion % is fitted, the cover 32 is detachably coupled to the suction nozzle 3''. The engagement of the engaging recess 34 with the engaging projection 36 serves to prevent the cover 32 from being unintentionally detached from the suction nozzle 30, and is provided for the user to grasp so that the cover 32 normally covers the nozzle 3. Further, four ribs 38 are formed on the inner peripheral surface of the cover 32 to the closed end side of the cover 32. These ribs 38 extend in the axial direction of the cover 32 and are disposed at intervals in the circumferential direction of the cover 32. In detail, as can be seen from Fig. 5, when the cover 32 is normally covered by the suction nozzle 30, the four ribs 38 clamp the arched portion 3〇d of the suction nozzle 30. Specifically, the two ribs 38 are in contact with one of the flat surfaces of the boarding portion 3〇d, and the two ribs 38 of the remaining portion are in contact with the other flat surface 3〇e of the arched portion 30d. In addition, Fig. 5 shows that the four ribs 38 can not only clamp the arched portion 30d in the first position shown by the solid line, but also from the first! The posture to the arched portion _, that is, the second posture shown by the two-point chain line of the nozzle 321853 201130433 30 relatively rotated by about 90 degrees, can also clamp the arched portion 30d. By clamping the arched portion 30d by the ribs 38 described above, the cover 32 and the suction nozzle 30 are coupled to each other in the circumferential direction regardless of the posture of the arched portion 30d. On the other hand, as can be seen from Fig. 1, The strips 13 of the cover 32 and the strips 11 of the corresponding tube 10 are integrated on the same line. That is, when the cover 32 is normally covered by the suction nozzle 30, the strips 13 of the cover 32 are positioned in the circumferential direction of the tubular body 10 and the cover 32 at the corresponding strips 11 of the tubular body 10. On the other hand, the large diameter portion 30a of the suction nozzle 30 is bonded not only to the end piece 18 of the tobacco crucible 12 but also to the base end of the tubular body 10 in a detachable manner by the bonding means 40. The bonding device 40 is as shown in detail in Figs. 6 and 7, and the bonding device 40 will be described below. As shown in Fig. 6(A), the base end of the tubular body 10 has a circumferential groove 42 on its inner peripheral surface. The circumferential groove 42 is opened at the base end surface of the pipe body 10, and an annular stopper surface 44 is formed on the inner circumferential surface of the pipe body 10. On the other hand, the large diameter portion 30a of the suction nozzle 30 is integrally formed with a flange 46 on its outer peripheral surface, and the flange 46 is positioned closer to the proximal end side of the tubular body 10 than the engaging projection 36. When the cover 32 is normally covered by the nozzles 30, the engaging projections 36 are fitted into the engaging recesses 34 in a state where the end faces of the cover 32 abut against the flanges 46. That is, the flange 46 functions as a stopper to the cover 32 for determining the axial position of the cover 32 with respect to the suction nozzle 30. Further, when the cover 32 is normally covered, it can be seen from Fig. 2 that it should be noted that the predetermined interval is ensured between the inner face of the closed end of the cover 32 and the end of the suction nozzle 30 13 321853 201130433. Further, the flange 46 has an outer diameter which is slightly smaller than the inner diameter of the circumferential groove 42. Therefore, as is understood from Fig. 6 (1), the flange 46 is partially in the state of entering the circumferential groove 42. Further, an annular spring '(4) (four) 0 ring 48 is attached to the outer peripheral surface of the large diameter portion 3〇a of the suction nozzle 30. The loop 48 is interposed between the end surface of the flange 46 on the opposite side of the engaging projection 36 and the stop surface & In detail, the 0-ring 48 has an outer diameter smaller than the inner diameter of the circumferential groove 42, and the width Dd in the free state is, for example, the same as the circumferential groove 42. Therefore, as described above, when the flange 46 partially enters the circumferential groove 42, the ring 48 is in a state of being compressed between the flange 46 and the stopper surface 44 toward the axis of the nozzle 3, and thereafter, The width Di of the ring 48 is from Fig. 6 (the illusion is known to be smaller than the aforementioned width D. When the 0 ring 48 is in the above-described compressed state, the annulus 48 is such that the nozzle 3 is detached from the base end of the tube 10 In the direction of the ejection, the nozzle is pushed 3 〇, but the detachment of the nozzle 30 is prevented by the nozzle 30 being snapped to the tube body 1. In detail, the nozzle 30 is large. The diameter portion 30a has one or more locking claws 50 on its outer peripheral surface, and in the case of this embodiment, there are two locking claws 50. These fastening claws 50 are separated from each other in the diameter direction of the suction nozzle 30, and The guide ring 52 is formed on the inner peripheral surface of the tubular body 10, and the guide groove 52 is formed in the tubular body 1 The diametrical directions are separated from each other for receiving the corresponding locking claws 50. Each of the guiding grooves 52 has a seat facing the front end side of the pipe body 10, and the locking claws 50 abut against the 321853 14 2 with a predetermined thrust. 01130433 This socket is obtained by the aforementioned spring thrust of the nozzle 30, that is, the 0 ring 48 restoring force generated by the compression of the 0 ring 48. As described above, as long as the buckle claw 50 is pushed When the bearing is pressed against the guide groove 52, the suction nozzle 30 is surely coupled to the base end of the tubular body 10, and the suction nozzle 30 does not fall off from the tubular body 10 together with the cover 32. The shape is as follows. As can be seen from Fig. 6(B) and Fig. 7, the guide groove 52 has an axial direction portion 52a which extends in the axial direction of the tubular body 10 and which is open at the stop surface 44 of the circumferential groove 42 described above. And a circumferential direction portion 52b connected to the inner end of the axial direction portion 52a. The circumferential direction portion 52b extends from the inner end of the axial direction portion 52a by a predetermined length in the circumferential direction of the tubular body 10. Preferably, the formation is performed. Among the two groove walls of the axial direction portion 52a, at least the groove wall facing the end surface of the circumferential direction portion 52b is not parallel to the axis of the pipe body 10, but is inclined in the extending direction of the circumferential direction portion 52b. Among the two groove walls forming the circumferential direction portion 52b, the groove wall on the side of the stopper surface 44 is provided before In particular, a recess is formed in the groove wall, and the recess cooperates with the end surface of the circumferential portion 52b to form a concave claw seat 54 that allows the insertion of the locking claw 50. Therefore, When the locking claw 50 is intended to enter the claw seat 54 (the combined position of the coupling device 40), the claw seat 54 is bounded from the three-way locking claw 50 for preventing the locking claw 50 from moving out of the tubular body 10. And the movement of the locking claws 50 toward the circumferential direction of the pipe body 10. As a result, not only the sway of the suction nozzle 30 in the axial direction of the pipe body 10 but also the swaying in the circumferential direction of the pipe body 10 is prevented. In the case of the aroma suction pipe, first, the user 15 321853 201130433 pulls the cover 32 straight out of the suction nozzle 30 toward the axis of the suction nozzle 30, and unfastens the engagement of the engaging recess 34 of the cover 32 with the suction nozzle 30. When the projections 36 are engaged, if the lid 32 is further pulled apart, as shown in Fig. 8, the lid 32 is removed from the suction nozzle 30, and the nozzle 3 is exposed. Further, when the cover 32 is pulled away from the suction nozzle 30, since the card 4 claw 50 of the suction nozzle is inserted into the claw seat 54 of the guide groove 52, that is, the state in which the pipe body 10 is engaged, the suction nozzle 30 does not It will come out of the tube 10 together with the tobacco crucible 12. In this state, the user grasps the arched portion 30d of the nozzle 3 horizontally and sucks through the nozzle 30, thereby enjoying the original flavor and taste of the tobacco in the tobacco crucible 12, and adding The aroma of the spice of cut tobacco. In detail, since the tobacco crucible 12 is filled with shredded tobacco and aroma components volatilized from the fragrance, the user's suction generates air that reaches the user's mouth through the tobacco crucible 12 and the suction nozzle 30 from the front end of the tubular body. flow. Therefore, the D aroma component is guided to the user's mouth together with the air flow, and as a result, the user can enjoy the aroma component without igniting the tobacco. Further, at the time of suction, the user sandwiches the upper and lower circular arc faces 10a of the tubular body 1 于 between the middle and lower index fingers, so that the tubular body can be stably held. On the other hand, when the tobacco concealer 12 reaches the use limit, as shown in Fig. 9, the user can remove the tobacco g 12 from the lid body 1 and the nozzle 32 and the nozzle 3Q. Regarding the removal of the tobacco E 12 here, it is described in detail below with reference to FIG. First, when the aroma pipette is in the non-use state shown in the figure, the user pushes the cover 32 toward the arrow F of the first () arrow (A), that is, toward the 321853 201130433 pipe ίο. At this time, the end of the cover 3? 2 and the end of the flange nozzle 30 of the suction nozzle 3 are in a state of abutting against the flange 46 of the end piece 18 of the tobacco crucible 12, so that the cover 32 is pushed. The suction 3 and the tobacco S12 are moved toward the front end side of the tube (4) toward the general direction. ^ Outside the movement of the tobacco 匣12 here _ If the movement is reversed, a gap G is ensured between the flange of the end piece 16 in the tobacco crucible and the annular projection 管 of the tubular body 1G (refer to Fig. 2). ) is allowed. The movement of the above-mentioned suction nozzle 3G, as shown in Fig. 1G (1), causes the locking claw 50 to be pulled out from the claw seat 54 of the guiding groove 52, and on the other hand, the flange 46 of the suction nozzle 3 and the tubular body 10 are The ankle ring 48 between the stop faces 44 is more constricted, and the width of the 0 ring 48 is further reduced from D1 to D2. After that, as long as the user-side maintains the above-mentioned lid & push, the lid 32 is rotated about its axis toward the direction of the arrow c in the first diagram (8) (counterclockwise as viewed from Fig. 7). As described above, the cover 32 and the suction nozzle 30 are integrally joined in the circumferential direction by the aforementioned ribs, so that the suction nozzle 30 and the tobacco g 12 are also rotated together with the cover %. Here, the rotation of the suction nozzle 30 causes the locking claw 5 to move from the circumferential direction portion 52b of the guide groove to the axial direction portion 52a (the release device 4 is released). In this state, as long as the user releases the pressing of the cover 32, the restoring force of the 0-ring 48 in the compressed state pushes the suction nozzle 3 〇 in the direction of ejecting from the tubular body 1〇. Therefore, the width of the loop 48 is returned from A to Dd, and on the other hand, the snap claw 5G is moved along the axial direction portion 52a of the guide groove 52 to the open end side of the guide groove 52. 321853 17 201130433 From this state, the user pulls the cover 32 in the direction of the arrow R in FIG. 10(C) by holding the cover 32, whereby the locking claw 50 can be pulled out from the guide groove 52, and The tobacco crucible 12 can be pulled out from the tubular body 10 and the suction nozzle 30. As a result, as shown in Fig. 9, the tobacco crucible 12 is easily removed from the tubular body 10. Thereafter, the tobacco crucible 12 is separated from the suction nozzle 30, and the end piece 18 of the new tobacco crucible 12 is inserted into the suction nozzle 30, whereby the new tobacco crucible 12 is bonded to the suction nozzle 30. The user inserts a new tobacco rod 12 into the tube body 10 while holding the lid 32, and positions the locking claw 50 of the nozzle 30 at the open end of the corresponding guide groove 52 of the tube body 10. Next (refer to Fig. 7), the large diameter portion 30a of the suction nozzle 30 is pushed into the base end of the tubular body 10, and the locking claw 50 is inserted into the axial direction portion 52a of the guide groove 52. At this time, the zero ring 48 of the suction nozzle 30 is sandwiched between the flange 46 of the suction nozzle 30 and the stop surface 44 of the pipe body 10, so that the snap claw 50 is positioned at the guide groove along with the compression of the zero ring 48. The circumferential direction portion 52b of 52 (refer to Fig. 10 (B)). Thereafter, as long as the user maintains the push-in state of the cover 32 and the suction nozzle 30, the cover 32 is rotated in the clockwise direction, and the cover 32 is integrally coupled to the suction nozzle 30 in the circumferential direction as described above, so that the suction nozzle 30 and tobacco 匣12 also rotate clockwise. Therefore, the locking claws 50 are in contact with the end faces of the circumferential direction portion 52b (refer to Fig. 10(A)). In this state, when the user releases the thrust of the cover 32 and the suction nozzle 30, as in the sixth As shown in Fig. (B), the locking claw 50 is again fitted into the claw seat 54 of the guiding groove 52, and at this point, the replacement of the tobacco rod 12 is completed. At this time, the strip 13 of the cover 32 is of course aligned on the same line as the strip 11 corresponding to the 18 321853 201130433 tube 10. Further, the replacement of the tobacco crucible 12 may be performed by inserting the new tobacco crucible 12 into the tubular body 10 after inserting the new tobacco crucible 12 into the tubular body 10. With regard to the replacement of the tobacco crucible 12, since the suction nozzle 30 is held by the cover 32, the user's finger does not directly contact the suction nozzle 30. Therefore, the user can hygienically replace the tobacco crucible 12. Alternatively, the replacement of the tobacco crucible 12 can be carried out without using the lid 32. That is, at this time, the user is in the state in which the suction nozzle 30 is directly held, and the operation of pushing or rotating the suction nozzle 30 described above is performed. Regardless of whether or not the lid 32 is used, since the tobacco sheet 12 to be replaced is pulled out from the tube body 10 together with the nozzle 30, the tobacco sheet 12 can be pulled out from the tube body 10 more reliably and easily, and further, it is pulled out. The tobacco crucible 12 itself does not fall off the tube body 10 unexpectedly. The present invention is not limited to the aroma suction pipe of the above embodiment, and various modifications are possible. For example, the aroma pipette can use aroma containing a variety of aroma generating materials to produce a crucible instead of the tobacco crucible 12, in which case the user can enjoy the aroma component released from the aroma generating material. Further, the tubular body 10 and the cover 32 may have a pattern divided by a continuous pattern on their outer peripheral faces instead of the strips 11, 13. At this time, the pattern portion of the tube body 10 and the pattern portion of the cover 32 are aligned with each other when the cover 32 covers the nozzle 30 to form a continuous pattern. Furthermore, the bonding device 40 can replace the 0 ring 48' with an elastic member such as a compression coil spring. In addition, the tobacco PCT does not impair the function of the bonding device 4, [Simple description] nozzle and cover, etc. The specific structure can be arbitrarily changed.
