Description

【０００１】
【発明の属する技術分野】
本発明は蓋圧式の液体噴出容器に関する。尚図示例はすべて噴霧容器を示すが、周知のように該噴霧容器は、そのノズルを変えることで噴霧することなく液体のまま、又泡状としても噴出可能であり、よって噴霧容器を、液体噴出容器の代表例としたものである。
【０００２】
【従来の技術】
例えば蓄圧式の噴霧容器として、図２０が示すように、容器体201 内へ小径シリンダ202 を垂下すると共に、該シリンダ内から上方付勢されて起立する大小両径の筒状ピストン203 ，204 付きの筒部材205 の上部外面へ、ノズル孔付きの押下げヘッド206 下面から筒状連結部207 を介して垂下する大径シリンダ208 を上下動可能にかつ大径シリンダ頂板の弁孔と筒部材上面から起立する弁体とで吐出弁を形成させて嵌合させ、又容器体口頸部外面へ下半筒部を嵌合させた装着筒209 から、内向きフランジを介して起立させた上部小内径の保持筒部210 内へ、上記大径シリンダ208 を抜出し不能に、かつ下降可能に嵌合させた噴霧容器が知られている。該噴霧容器は、付勢に抗して押下げヘッド206 を押下げすると、筒部材205 が共に押下げられることで大小径両シリンダおよび筒部材205 内が高圧化し、すると大小両筒状ピストン203 ，204 の径差、つまり受圧面積の差により、大径シリンダ208 に対して筒部材205 が下降してその筒部材上端面から突出する吐出弁体211 が大径シリンダの頂板中心の弁孔から離れて吐出弁212 が開き、よって上記両シリンダおよび筒部材内の高圧化された液体がノズル孔213 から噴霧し、又押下げヘッドの押下げ終了により、上記両シリンダ等内が高圧状態を解消するとスプリングの上方付勢で大径シリンダに対して筒部材が上昇して吐出弁212 が閉じ、該状態から押下げヘッドを離すと筒部材上昇により小径シリンダ202 下端内面の吸込み弁214 が開き、吸上げパイプを介して容器体内液体を両シリンダ等内へ吸込むものである。
【０００３】
【発明が解決しようとする課題】
従来の蓋圧式液体噴出容器は、噴出終了後、ノズル孔内面等に付着した液体をそのままとするから、液体の種類によってはその付着液体が乾燥することで液体中の成分が徐々に蓄積されて目塞りの原因となることが考えられる。
【０００４】
本発明は押下げヘッドの外周壁内方にエアポンプ室を形成し、該室内空気が押下げヘッド下降により圧縮されて高圧化し、該高圧空気が、吐出弁の閉塞を待って吐出弁上方に設けた弁室内へ入りかつノズル孔を通って放出するよう形成することで、ノズル孔内に付着した液体を共に噴出できるよう設けたものである。
【０００５】

【００１７】
【発明の実施の形態】
まず図１から図７が示す実施形態について説明すると、１は口頸部を起立する容器体、２はその口頸部上端面へ、外向きフランジ３を載置させて容器体内へ垂下する小径シリンダで、その底部内に吸込み弁４を有し、又下端から吸上げパイプ５を垂下する。その小径シリンダ内からはスプリングで上方付勢させて大小径の両筒状ピストン６，７を上下に有する筒部材8aを起立する。又大径筒状ピストン６上面からは吐出弁体９を起立する。図示例にあっては小径シリンダ内空間を狭少化させて、ピストンの効率を高めるための挿入部材10をシリンダ底部から起立し、筒部材8a下降時にその挿入部材上部が筒部材下部内へ遊挿されるよう設けている。
【００１８】
上記筒部材8aの上部外面へ、後述の押下げヘッド下面から筒状連結部を介して垂下する大径シリンダ11を上下動可能に嵌合させている。図示例において大径シリンダ11は周壁下端を大外径部とし、大径シリンダ上面を閉塞する頂板を外周部12a と、該外周部から起立する第１嵌合筒部12b と、該第１嵌合筒部上面を閉塞する中央部12c とで筒状頂部に形成し、該中央部中心に吐出弁孔13を穿設し、又その吐出弁孔を囲んで中央部上面から弁座筒14を起立する。又大径シリンダを上方へ延長して第３嵌合筒部15としている。16は吐出弁体９と吐出弁孔13とが形成する吐出弁である。
【００１９】
押下げヘッド21は頂壁22外周から外周壁23を垂下し、又頂壁中央部から上記第１、第３嵌合筒部間に嵌着させて第２嵌合筒部24を垂下している。第２嵌合筒部24が囲む頂壁中央部下面部分は下面開口の弁室25に形成し、該弁室はその上部を、下向き段部を介して小内径部とし、かつその上端部に、外周壁上方前部に穿設したノズル孔26と連通する液体吐出路27基端を開口させている。
【００２０】
上記弁室25内へは、基筒部31上端から内向きフランジ32を介して弾性筒33を垂下する弾性弁筒34を設けて、弁座筒の内外面へ嵌合させ、かつその基筒部31を弁室の下部内面へ、基筒部上端面が下向き段部下面へ圧接する状態に嵌着させ、弾性筒33下部を弁座筒14の内面へ圧接させて排気弁35（図５参照）としている。該排気弁は後述エアポンプ室内空気を、筒状連結部36を構成する複数の筒部間に設けた溝が形成する通気路37を通って弁室内へ、その排気弁を介して放出可能とするものであり、図示例では既述第１、第２、第３の嵌合筒部12b ，24，15で筒状連結部36を形成し、第３嵌合筒部15の上端面および内面と、大径シリンダ筒状頂部の外周部12a 上面と、第１嵌合筒部12b 外面と、弁座筒14外方の大径シリンダの中央部上面と、弁座筒14外面から上面およびその弁座筒の上部内面に溝を設けて上記通気路37としている。
【００２１】
上記大径シリンダ11外面へは、容器体口頸部外面へ下半筒部を嵌合させた装着筒41から内向きフランジ42を介して起立する保持筒部43を、抜出し不能に、かつ下降可能に嵌合させている。その抜出し防止のために、保持筒上部は小内径部としており、既述大径シリンダ下端の大外径部上面を、その小内径部下端面へ係合させている。又図示例では上記内向きフランジ42外周から押下げヘッドの外周壁23よりも大内径の外周筒44を起立している。
【００２２】
押下げヘッド21の頂壁22下面と、該頂壁中央部と大径シリンダ11とを連結する筒状連結部36と、頂壁外周から垂下する外周壁23と、上記装着筒41との間に形成される空間とを利用して、装着筒に対する押下げヘッド21の下降および上昇で容積が減少し、又拡大する、外気吸入弁51付きのエアポンプ室52を形成する。
【００２３】
図示例では第１シール筒53と可動筒体58とをエアポンプ室下面閉塞の閉塞部としており、これ等は容器体に対して中間部材を介し固定させる。第１シール筒53は、図３等が明示するように保持筒部43の上部外面へ嵌着させた縦筒54上端から上内方へ弾性テーパ状筒55を突出して、その上端を第３嵌合筒部15の下部外面へ気密に、かつ摺動自在に嵌合すると共に、縦筒上端に外向きフランジ56を付設し、その縦筒54の上部外面から外向きフランジの下面外端まで適当数の通気溝57を穿設している。
【００２４】
又可動筒体58は、図３が示す、第１シール筒に対する下降位置において、保持筒部43外面へ付設したストッパ59上へ載置させた短筒60を有し、該短筒内面から上内方へ突設した内向きフランジ状壁61の内端面を、上記第１シール筒53の縦筒54下部外面へ気密にかつ摺動自在に嵌合させ、又短筒60上端から外方へ突設した外向きフランジ状壁62の外端を斜上下に拡開し、その先端面を押下げヘッド外周壁23の下部内面へ気密に、かつ摺動自在に圧接させ、上記縦筒54の下部外周面に対する内向きフランジ状壁61の摩擦抵抗よりも、外周壁23に対する外向きフランジ状壁62の摩擦抵抗を大としている。
【００２５】
上記第１シール筒53と可動筒体58とは外気吸入弁51を形成する。即ち、第１シール筒53に対して可動筒体58が図７のように上昇して短筒60上端面が外向きフランジ56下面に接したとき、内向きフランジ状壁61は縦筒54の通気溝穿設部分へ移動してエアポンプ室52内へ外気が流入可能とし、又図３が示すように可動筒体58が下降して内向きフランジ状壁61が通気溝57を有しない縦筒54の下部外面に接したとき、エアポンプ室内が漏出しないよう設けている。
【００２６】
図１から図７が示す、上記第１実施形態の作用について説明すると、数回押下げヘッド21を押下げ操作することで、大小径両シリンダ11，２内および筒部材８内が形成する加圧室内へ液体を入れることが出来、該状態から図２と図３が示すように更に押下げヘッド21を押下げする。既述従来例の場合と同様にこのとき吸込み弁４と吐出弁16との間の上記両シリンダ等が形成する加圧室内は等しく加圧されるが、両筒状ピストン６，７の受圧面積の差で筒部材8aは下降することとなって吐出弁16が開き、高圧液体を液体吐出路27を通ってノズル孔26から噴霧する。押下げヘッドの押下げ継続中は筒部材8aも吐出弁開放のままで共に下降する。該押下げヘッド下降時において可動筒体58も外周壁23との摩擦抵抗で下方へ押されるが、短筒60下端面が保持筒部43外面に付設したストッパ59に接すると下降を停止する。エアポンプ室52は押下げヘッドの下降と共に狭小化されて高圧化することとなり、該高圧空気は筒状連結部36に設けた通気路37を通り、更に排気弁35を開いて弁室25内へ抜け出ししようとするが、その弁室25内には上記高圧液体が充満しているため、排気弁35を開くことが出来ず、よってエアポンプ室内空気は更に高圧化することとなる。押下げヘッド21が下限まで達したとき加圧室内の高圧状態は解消され、よってスプリングの上方付勢により筒部材8aは上昇して吐出弁16を閉塞する。該吐出弁閉塞と同時に弁室25内の液体による高圧状態も解消されることとなり、すると図５のように弾性筒33の先端部が押されて弁座筒14内面から離れ、エアポンプ室52内高圧空気が即時に弁室25、液体吐出路27を通ってノズル孔26から噴出し、該噴出時にそのノズル孔内面等に残っていた液体を吹き飛ばすこととなり、エアポンプ室内の高圧状態解消と共に弾性筒先端部は弾性復元して排気弁35は閉塞する。
【００２７】
次いで押下げヘッド21を離すと、押下げヘッドは大径シリンダ、筒部材と共にスプリングにより押上げられ、すると可動筒体58は既述のようにその一部が第１シール筒53の外向きフランジ56下面に接するまで引上げられることとなり、このとき図７のように外気吸入弁51が開くことでエアポンプ室内に外気が流入して、エアポンプ室の負圧化を防止する。
【００２８】
エアポンプ室52下面の閉塞部、通気路37入口部分の形成、外気吸入弁51の形成等は図８から図１２が示すように変更できる。該変更なき部分については第１実施形態の場合と同様である。
【００２９】
図８が示す第２実施形態は、押下げヘッド21の外周壁23内へ有頂筒体71を嵌合させ、その有頂筒体の第２頂壁72に外気吸入弁51を設け、又有頂筒体の第２周壁と第３嵌合筒部15との各下部内面間を閉塞してエアポンプ室52を形成している。有頂筒体71は第２頂壁72外周から第２外周壁73を垂下するもので、その第２頂壁の中央部に挿通孔74を穿設して押下げヘッド頂壁中央部から垂下する第２嵌合筒部24を挿通させ、かつ第２外周壁73を押下げヘッドの外周壁23内面へ嵌着させている。又第２頂壁72には弁孔75を穿設し、該弁孔から第２頂壁上面外縁へ外気流入路76としての溝を穿設し、該溝と連通させて押下げヘッド外周壁23内面にも溝を縦設している。又第２頂壁72下面に接して第２嵌合筒部24の上部には基筒部77を嵌着させ、該基筒部上端に付設した弾性外向きフランジ状壁78で上記弁孔75下面を閉塞させて外気吸入弁51としている。その基筒部77下端面は第３嵌合筒部15上端面で支持させている。その第３嵌合筒部上端面には通気路37の入口部分としての溝を設けている。
【００３０】
保持筒部43の上端部外面には閉塞部としての第２シール筒79を嵌着させている。該第２シール筒は第２縦筒80上端から上内方へ弾性テーパ状筒81を、かつ外方へ外向きフランジ状壁82を、それぞれ突出して弾性テーパ状筒上端を第３嵌合筒部15の下部外面へ、又外向きフランジ状壁外面を第２外周壁73の下部内面へ、それぞれ気密に、かつ摺動自在に嵌合させている。
【００３１】
次に図９が示す第３実施形態について説明すると、小径シリンダの外向きフランジ３上面および外面に径方向および上下方向への通気溝3aを穿設し、容器体口頸部外面と装着筒41との間の間隙を介して外気とその通気溝とを連通させている。又装着筒41の内向きフランジ42下面に通気溝83a を周設し、該通気溝上方の内向きフランジ部分に適当数の通気孔84を穿設し、更に内向きフランジ上面にも通気溝83b を周設して通気孔と連通させている。その内向きフランジ上面の通気溝83b は保持筒部43の下部外面、又は内向きフランジ外周から起立する外周筒44の下部内面のいずれかに嵌着させた基筒部85下端に付設した弾性フランジ86で密閉して、これ等で外気吸入弁51を形成する。但し上記内向きフランジ42上面の通気溝83b は必しも必要としない。
【００３２】
更に大径シリンダ11の下部外面には第３シール筒87を、又押下げヘッド外周壁23の下部には第４シール筒88を、それぞれ付設して第３シール筒を保持筒部43の上部内面へ、又第４シール筒下部を外周筒44の上部内面へ、それぞれ気密に、かつ摺動自在に圧接する。該第３実施形態にあっては大径シリンダから起立する第３保持筒を有せず、大径シリンダ11外径と、押下げヘッドから垂下する第２嵌合筒部24外径とを同径としているが、押下げヘッド下降で、保持筒部43内へ第２嵌合筒部24が挿入可能であればよく、よって第２嵌合筒部は小外径でもよい。尚作動部材上限は、第３シール筒87上端が、保持筒部43上端の小内径部下面へ接することで定まる。
【００３３】
図１０が示す第４実施形態は、大径シリンダ下部外面に第５シール筒91を、又押下げヘッド外周壁の下部に第６シール筒92を、それぞれ付設して第５シール筒を保持筒部43の上部内面へ、又第６シール筒92下部を外周筒44の上部内面へ、それぞれ気密に、かつ摺動自在に圧接すると共に、押下げヘッド外周壁の下方一部に通気孔93を穿設して、該通気孔内面を、第６シール筒上面ないしその一部から突出して形成した弾性弁板92a で密閉して外気吸入弁51としている。該実施形態の場合も第３実施形態の場合と同様に第３保持筒を有せず、大径シリンダ11上端と第２保持筒部24下端との間に通気路37としての溝を開口させている。
【００３４】
図１１は第５実施形態を示す。該実施形態にあっては、第３、第４実施形態の場合と同様に大径シリンダ下部外面に第７シール筒101 を付設して該シール筒外面を保持筒部43の上部内面へ気密に、かつ摺動自在に圧接するが、押下げヘッド外周壁23下部と外周筒44の上部との間には第８シール筒102 を設け、該第８シール筒で上記両筒間のシールを行うと共に、その第８シール筒と押下げヘッド外周壁23とで外気吸入弁51を形成している。
【００３５】
該実施形態にあっては、外周壁23の下部を下向き段部103 を介して小外径部104 とし、かつ該小外径部の更に下部外面に適当数の通気用縦溝105 を穿設している。又外周壁23の下部内面にはストッパリング106 の上部を嵌着させ、該リングの下部外面から小外径部の下端面に接して複数の係合突子107 を、小外径部外面よりも外方へ突出させて設け、その小外径部外面と外周筒44の上部内面との間に第８シール筒102 を上下動可能に嵌合させている。第８シール筒102 は縦筒108 内面から下内方へフランジ状壁109 を突出して該フランジ状壁の内端部下面を係合突子107 の上面へ係合させると共に、又縦筒108 外面へ、中間部小外径で上下両端部を大外径とする短筒状の摺接部110 を付設してその外面を外周筒44の上部内面へ、気密にかつ摺動自在に圧接させている。
【００３６】
該第８シール筒102 は、小外径部104 外面に対するフランジ状壁109 の摩擦抵抗よりも、外周筒44に対する摺接部110 の摩擦抵抗を大とするもので、押下げヘッド21押下げにより第８シール筒102 に対して外周壁23が下降して、下向き段部103 に縦筒108 上端面が接することで、外周壁23と第８シール筒102 とが共に下降し、又押下げヘッド上昇時にあっては、まず第８シール筒102 に対して外周壁23が上昇し、係合突子107 上面にフランジ状壁109 が接することで、第８シール筒102 は外周壁23と共に外周筒44に対して上昇可能とする。尚縦筒108 上端が下向き段部103 下面に接する状態ではフランジ状壁109 内面は、縦溝105 を有しない小外径部104 外面へ気密に接し、又フランジ状壁下面が係合突子107 上面に接する状態では、縦溝105 内および係合突子107 間の間隙を介してエアポンプ室52内と外気とは連通する。
【００３７】
図１２は第６実施形態を示す。該実施形態は大径シリンダ11を上方延長させて設けた第３嵌合筒部15を第２嵌合筒部24外面へ嵌合させ、該第３嵌合筒部上端と押下げヘッド21の頂壁下面との間にエアポンプ室52と弁室25とを連通する通気路37の基端を開口させている。尚図示例においては押下げヘッド21の内面へ内面覆合筒121 を、該筒の頂壁中心に穿設した透孔内へ第２嵌合筒部24を挿入させ、かつその頂壁外周から垂下する周壁23b を押下げヘッドから垂下する周壁23a 内面へ緊密に嵌合させて設けている。従って該実施形態においては押下げヘッド外周壁23を上記両周壁で形成することとなる。このようにすることでその外周壁の剛性を高めて外周壁内面を真円に保つことが容易となり、後述摺動筒体とのシール性を高めることが出来る。
【００３８】
保持筒部43は、その中間部外面を真円の弁座面122 とし、かつ保持筒上部を内向きフランジを介して小径部123 とし、上記弁座面と内向きフランジ上面との間を、それ等弁座面と小径部とに対して中径部124 とする。従ってそれ等小径部、中径部に対して弁座面は大径である。
【００３９】
上記小径部123 外面へは第９シール筒125 を嵌着させる。該第９シール筒は小径部外面へ嵌着させた縦筒126 上端から弾性テーパ状筒127 を上内方へ突出して、その上端を第３嵌合筒部15の下部外面へ気密に、かつ摺動自在に嵌合させる。又縦筒126 外面から適当数の係合板128 を放射状に突出する。
【００４０】
131は摺動筒体で、押下げヘッド外周壁23の下部内面へ気密にかつ摺動自在に圧接させたシール用短筒132 から内向きフランジ状部を介して連続筒部133 を垂下し、該筒部の下部内面から上内方へ弾性テーパ状筒134 を突出し、該筒上端を、上記係合板128 の内外方向中間の下面に当接させている。これ等第９シール筒と摺動筒体とがエアポンプ室52下面の閉塞部を形成する。連続筒部133 と係合板128 との間、および係合板128 よりも下方の摺動筒体部分と該部分と対向する保持筒部分との間、更に連続筒部133 下面と装着筒の内向きフランジ42との間には、それぞれ間隙が形成され、又それ等間隙のうち連続筒部下端と内向きフランジとの間、および係合板128 下方の摺動筒体部分と該部分に対向する保持筒部分との間、更に上記各係合板間の各間隙はエアポンプ室52内への外気流入路を形成する。
【００４１】
摺動筒体131 の弾性テーパ状筒134 と弁座面122 および中径部124 が外気吸入弁51を形成し、押下げヘッド下降による弾性テーパ状筒下降で弁座面122 外面へ弾性テーパ状筒上端部外面が気密に嵌合することで外気吸入弁51が閉じ、又押下げヘッド21と共に摺動筒体が上昇することで弾性テーパ状筒134 は弁座面122 から中径部124 外方へ抜出し、該抜出しで外気吸入弁51が開く。尚外気吸入弁閉塞時、連続筒部133 下端は内向きフランジ42に接して保持筒部43に対して停止する。
【００４２】
その外気吸入弁開閉のため、外周壁23に対するシール用短筒132 の摩擦抵抗を、弁座面122 に対する弾性シール筒134 上端の摩擦抵抗よりも大として、シール用短筒132 が外周壁23内面へ圧接停止する状態で弾性テーパ状筒134 は弁座面122 に対して摺動可能で、連続筒部133 下端が内向きフランジ42に接して摺動筒体131 の下降不能となった場合、および弾性テーパ状筒134 上端が係合板128 下面に接して摺動筒体131 が上昇不能となったときにだけ、シール用短筒132 は外周壁23内面に対して上下動する。
【００４３】
図１３から図１６は第７実施形態を示す。該実施形態容器は、図１２までの容器と異るタイプで、かつ公知の液体噴出容器を、本発明の液体噴出容器に改良したものである。
【００４４】
まず公知部分について簡単に説明すると、１は胴部上端から肩部を介して口頸部を起立する容器体で、該容器体内には、底部内面に吸込み弁を有するシリンダ２上端に付設した外向きフランジを、口頸部上端面へ係合させることで貫設されている。
【００４５】
そのシリンダ内からは、筒部８上端に押下げヘッド21を嵌合させた作動部材28が上方付勢させて起立させてあり、該作動部材の上下動で、容器体内液体がシリンダ下端から垂下する吸上げパイプおよび吸込み弁を介してシリンダ内へ吸込みされ、又該シリンダ内液体は、作動部材が有する吐出弁16を通って押下げヘッドのノズル孔から吐出可能に設けてある。
【００４６】
上記シリンダ上端の外向きフランジは、容器体口頸部外面へ螺合させた装着筒41上端の内向きフランジ42a と、口頸部上端面とで挟持される。図示例ではその内向きフランジ内端縁と筒部８に設けた上向き段部へ係合させて筒部の上限としているが、公知のように他の手段で行ってもよい。
【００４７】
本発明にあっては、筒部８と押下げヘッド21との連結を次のように行っている。即ち、押下げヘッド頂壁の中央部から、連結筒部135 を垂下し、該筒部の下部を大内径部として該大内径部内へ筒部８の上部を抜出し不能に嵌着させている。上記連結筒部は、ノズル孔26と連通する筒孔136 をその筒部中心に有し、かつその筒孔中心に該筒孔よりも小外径でかつ下端部に下向き段部を周設するスプリング押え棒137 を垂下する。
【００４８】

[0023]
In the example shown in the figure, the first seal cylinder 53 and the movable cylinder 58 are used as closed portions for closing the lower surface of the air pump chamber, and these are fixed to the container body via an intermediate member. As clearly shown in FIG. 3 and the like, the first seal cylinder 53 protrudes from the upper end of the vertical cylinder 54 fitted to the upper outer surface of the holding cylinder portion 43 upward and inwardly, and the upper end of the first seal cylinder 53 is the third end. Fits airtightly and slidably to the lower outer surface of the fitting tube portion 15, and has an outward flange 56 attached to the upper end of the vertical tube, from the upper outer surface of the vertical tube 54 to the lower surface outer end of the outward flange. An appropriate number of ventilation grooves 57 are formed.

  The operation of the first embodiment shown in FIGS. 1 to 7 will be described. By pressing the pressing head 21 several times, the large and small diameter cylinders 11 and 2 and the cylindrical member 8 are formed. Liquid can be put into the pressure chamber, and the push-down head 21 is further pushed down from this state as shown in FIGS. As in the case of the conventional example described above, the pressure chamber formed by the two cylinders between the suction valve 4 and the discharge valve 16 is equally pressurized, but the pressure receiving areas of the two cylindrical pistons 6 and 7 are the same. As a result of this difference, the cylinder member 8a is lowered, the discharge valve 16 is opened, and the high-pressure liquid is sprayed from the nozzle hole 26 through the liquid discharge path 27. While the pressing head continues to be pressed, the cylindrical member 8a is also lowered while the discharge valve is open. When the pressing head is lowered, the movable cylinder 58 is also pushed downward by frictional resistance with the outer peripheral wall 23. However, the lowering stops when the lower end surface of the short cylinder 60 comes into contact with the stopper 59 provided on the outer surface of the holding cylinder portion 43. The air pump chamber 52 is narrowed and increased in pressure as the push-down head is lowered, and the high-pressure air passes through the air passage 37 provided in the cylindrical connecting portion 36, and further opens the exhaust valve 35 into the valve chamber 25. The valve chamber 25 is filled with the high-pressure liquid, but the exhaust valve 35 cannot be opened, so that the air pressure in the air pump chamber is further increased. When the pressing head 21 reaches the lower limit, the high pressure state in the pressurizing chamber is canceled, and the cylinder member 8a is raised by the upward biasing of the spring to close the discharge valve 16. At the same time as the discharge valve is closed, the high pressure state due to the liquid in the valve chamber 25 is also eliminated. Then, the tip of the elastic cylinder 33 is pushed away from the inner surface of the valve seat cylinder 14 as shown in FIG. High-pressure air is immediately ejected from the nozzle hole 26 through the valve chamber 25 and the liquid discharge path 27, and the liquid remaining on the inner surface of the nozzle hole at the time of the ejection is blown off.Air pump roomAs the internal high pressure state is eliminated, the tip of the elastic cylinder is elastically restored and the exhaust valve 35 is closed.
