Description

【０００１】
【発明の属する技術分野】
本発明は正倒立両用のトリガー式液体噴出容器に関する。
【０００２】
【従来の技術】
容器体口頸部に嵌合させた装着筒上部内から、該装着筒よりも小外径で有頂の基筒部を起立し、該基筒部頂壁を貫設して起立する主筒前面からシリンダを、主筒上端部から射出筒を、それぞれ前方突設し、射出筒前部に枢着させて垂設したトリガーの上方後部に、上記シリンダ内へ嵌合させたプランジャ前部を係合させたトリガー式の液体噴出容器が広く使用されている。又液体噴出による容器体内液体減少による負圧化を、基筒部頂壁の前部内とシリンダ内とを連通する外気供給路を設けて、シリンダ内プランジャが前限にある状態ではシリンダ内面側がプランジャにより閉塞されていて、トリガー操作によりプランジャがシリンダ内を後退したとき開通するように設けることで、上記負圧化を解消することも知られている。

【０００９】
第５の手段として、上記第１、第２、第３又は第４の手段を有すると共に上記容器体は、胴部の中心軸線に対して下方を大きく前方へ張出しさせると共に、吸上げパイプ56は下前方へ屈曲させて下端を容器体底壁の前端部に近接させた。
【００１０】
【発明の実施の形態】
以下図面について説明する。まず従来公知の部分について簡単に説明すると、 1 は容器体、２はその容器体口頸部外面へ螺合させた装着筒で、該装着筒内から該装着筒よりも小外径で有頂の基筒部３を、装着筒上端に付設した内向きフランジ下面へ、基筒部の下部外面に付設した外向きフランジ４を係合させて起立し、該基筒部頂壁５の後部から主筒６を、該主筒下部を頂壁に貫設して起立する。図示例では頂壁上方の主筒部分を内外二重筒で形成しており、その外筒部分前面からシリンダ７を、外筒部分上端から射出筒８を、それぞれ前方突出し、シリンダ後部下壁部分を兼用壁として設けた外筒部分下方の外向きフランジ壁９外周から周壁10を垂設して該周壁を上記基筒部３の上方部分外面へ嵌合させている。
【００１１】
上記射出筒８の前端部には連結筒を介してノズル筒11を回動可能に嵌合させ、又射出筒前部に枢着させてトリガー12を揺動可能に垂下し、該トリガーの上部後面に、上記シリンダ内へ嵌合させたプランジャ13の前端部を係止させている。尚14は吸込み弁、15は吐出弁で、上記トリガー操作によるプランジャのシリンダ内摺動で容器体内液体を上記主筒下端から垂下させた吸上げパイプ、吸込み弁を介してシリンダ内へ吸込み、かつ該シリンダ内液体を吐出弁、射出筒を介してノズル筒が有するノズル孔から噴出可能としている。尚液体噴出により容器体内が負圧化すると、基筒部３頂壁の前部に穿設した第１透孔16a とシリンダ底部に穿設した第２透孔16b とを連通させて形成している外気供給路16が、トリガー引寄せ操作によるプランジャ13後退の際、上記第２透孔が開口されることで、そのシリンダを介して外気と基筒部３内とを連通し、上記負圧化を解消する。
【００１２】
本発明にあっては上記基筒部３の上部内に空間を残して、その基筒部内から倒立時用液体吸込み筒21を垂下させる。又その液体吸込み筒内へは、後述の弁付き筒と吸上げパイプ取付け筒とを嵌合させる。
【００１３】
まず図１から図８が示す第１実施形態について説明すると、上記液体吸込み筒 21は、該筒上面を閉塞する頂板22後部から図５が示すように垂下筒23を垂下し、該垂下筒下端から内向きフランジ24を突設し、該フランジ内周を上記垂下筒に貫通させた嵌合筒25の下部外面に付設している。該嵌合筒と垂下筒23とは同一の軸線を有する二重筒状とする。又既述外気供給路16の第１透孔16a 下方の頂板部分を隆起させて、上面閉塞の短筒26を起立している。
【００１４】
又基筒部３の下端よりも下方へ垂下する液体吸込み筒21部分の上端前部に倒立時用の液体吸込み口27を図４が示すように穿設し、その吸込み口左右方向中間部下端から、その上方の基筒部前部内面に、後面を斜下前方への傾斜面28とするガイド板29を縦設し、かつ該板上部を上記短筒内および垂下筒23の前面まで延長している。又上記液体吸込み口27の左右両側からは、斜上後方へ側板30,30 を起立し、これ等両側板とこれ等両側板間後方の垂下筒23前面とで弁室31を形成している。
【００１５】
弁付き筒41は、図６が示すように第１横壁42外周から第１外筒43を垂下し、又その第１横壁後部を開口して、該開口周縁から第１縦筒44を垂下し、又その横壁前部に下部小径のテーパ状弁座45を設けてその弁座下端を弁孔46としている。図が示すようにその弁座上方前部の第１外筒上端部は、既述倒立時用の液体吸込み口27を閉塞しないよう切欠き47するとよい。第１縦筒44の下端前部も切欠きして開口48する。
【００１６】
吸上げパイプ取付筒51は、図７が示すように、第２横壁52外周から第２外筒53を垂下し、又その第２横壁52後部を開口して、該開口周縁から第２縦筒54を垂下している。図示例では第２横壁の前部上面を凹面55として既述弁座45を有する第１横壁部分下面との間に間隙を設けている。第２縦筒54内へは吸上げパイプ56の上部を緊密に嵌着させている。
【００１７】
図示例では倒立時用液体吸込み筒21の嵌合筒25下部を、弁付き筒41の第１縦筒44上部内へ嵌合させ、又その第１縦筒下端面と吸上げパイプ取付筒51の第２縦筒54上端面とを水密に接して、それ等吸上げパイプ56と、第２縦筒54と、第１縦筒44と嵌合筒25と主筒６とで、正立時用の液体吸込み路を形成している。
【００１８】
既述テーパ状弁座45上へは玉弁61を載置し、該玉弁と弁座下端の弁孔46とで、正立時用の空気吸込み防止弁62を形成する。その玉弁61の上部前面へは、既述倒立時用液体吸込み筒21の傾斜面28下端が近接するよう設ける。
【００１９】
又既述短筒26外面へは、図８が示すように筒体72上端面から等間隔に起立する複数の弾性螺条片73上端に弁板74を付設した弁部材75を設けて、上記筒体を短筒26外面へ嵌合させ、かつ弾性螺条片73の弾性で上記弁板74を、基筒部３頂壁前部に穿設した第１透孔16a 下面へ圧接させて閉塞させる。これ等弁板と第１透孔とは外気吸入弁76を形成するもので、容器体内が負圧化したとき、その外気吸入弁を開いて基筒部３の上部内へ入った空気は、図５が示すように倒立時用液体吸込み口27から周方向へ離れて、液体吸込み筒21の上部外面に縦設した溝32を通って容器体内へ入るよう設けている。尚当然のこと乍ら、その溝は基筒部３の内面に穿設してもよい。
【００２０】
既述容器体１は、胴部の中心軸線に対して、下方内部を大きく前方へ張出しさせ、又吸上げパイプ56は中間部から下前方へ屈曲させて、その下端が形成する正立時用の液体吸込み口を、容器体底壁の前端部に近接させている。
【００２１】
図示例では、正立時用液体吸込み路を、吸上げパイプ56と第２縦筒54と第１縦筒44と嵌合筒25と主筒６とで形成したが、例えば第１縦筒44を上方へ延長して直接主筒下部内へ嵌合させて上記正立時用の液体吸込み路とすることも可能である。又図示例では、倒立時用の液体吸込み路を、倒立時用液体吸込み口27と、弁室31と、弁孔46と、第１、第２横壁42,52 間の間隙と、第１縦筒44に穿設した開口48とで形成するが、その開口48は、第１縦筒44への穿設に代えて、吸上げパイプ取付け筒の第２縦筒54を上方へ延長して、該延長筒部分に穿設してもよいことは当然である。
【００２２】
倒立時用液体吸込み口27は、図１、図２が示すように、容器体口頸部外面へ嵌合させる装着筒２の下端面よりも上方の口頸部部分内に位置させている。
【００２３】
尚既述外気吸入弁76の形成は、必要により設ければよく、又容器体下部の前方張出しおよび吸上げパイプ56の前方屈曲も同様である。
【００２４】
上記構成において、容器体内に適当量の液体を入れておき、容器体正立状態でトリガー操作をすると、倒立時用液体吸込み口27は容器体内液面上方で開口するが、その吸込み口から開口48にいたる倒立時用液体吸込み路の途中に正立時用空気吸込み防止弁62を設けているため、その倒立時用液体吸込み路を通って液面上方の空気がシリンダに入ることはなく、よって通常のトリガー式液体噴出容器の場合と同様に容器体内液体は、その正立時用液体吸込み路を通り、吸込み弁14を通ってシリンダ内へ吸込みされ、又そのシリンダ内液体はプランジャ後退によるシリンダ内高圧化で吐出弁15を通り、射出筒前端のノズル筒から噴出される。
【００２５】
次に容器体を倒立させると、吸上げパイプ56下端は液面上方へ露出し、倒立時用液体吸込み口27は水中に没し、又玉弁61は自重で弁室31上方へ移動し、よって正立時用空気吸込み防止弁62は開弁する。
【００２６】
該状態でのトリガー操作でシリンダ７内が負圧化すると、既述倒立時用液体吸込み路を通って開口48から正立時用液体吸込み路内へ入った液体はシリンダ７内へ吸込みされ、プランジャ後退によるシリンダ内高圧化で吐出弁15を開いて射出筒を通り、ノズル筒から噴出される。尚吸上げパイプ56下端は液面上方へ露出しているが、該パイプ内に入っている液体は、倒立時用液体吸込み路を介して容器体内液体と連通するため、該パイプ内液体の液面と容器体内液体の液面とはほぼ等しい位置にあり、よって上記シリンダ内への液体吸込み時に上記パイプ内を通って空気がシリンダ内へ入ることはない。該倒立使用時に液体が減少して容器体内が負圧化すると、プランジャ13後退で外気供給路16および外気吸入弁76が開き、このようにして基筒部３の上部内へ入った外気は、倒立時用液体吸込み筒21の上部外面に縦設した溝32を通り、気泡となって水中を上昇し、液面上方へ放出され、上記負圧状態を解消する。尚その溝32は倒立時用液体吸込み口27から周方向へ離れて設けてあるため、その倒立時用液体吸込み口27から吸込まれる液体と共に上記気泡が吸込みされることはない。
【００２７】
本発明は射出筒８が下向きで、かつ容器体がほぼ水平となった状態ででも液体噴出できるようにしている。
【００２８】
即ち、そのようにしたとき、倒立時用液体吸込み口27は下方（正立時における側方）へ開口することとなり、かつ正立時用空気吸込み防止弁62の玉弁61は弁座45を離れるが、弁室31前面の傾斜面28下端へ上部前面を接して停止する。このとき容器体胴部の下部前方張出し部分はその水平状態で下方へ張出すこととなり、吸上げパイプ56下端もその下方張出し部分内に位置することとなるため、その容器体水平状態で容器体内液面が上記倒立時用液体吸込み口27よりも上方にあれば、それ等両液体吸込み口は共に水中にあることとなり、よってトリガー操作で液体噴出出来る。
【００２９】
該容器体水平状態において更に液体が減少して容器体内液面が倒立時用液体吸込み口27よりも下方に位置することとなった場合は、シリンダ内が負圧化したとき、その吸込み口27から容器体内空気を吸込む筈であるが、上記のように玉弁61が傾斜面28に接していて弁座45に近接する位置にあるため、上記空気吸込みと同時に玉弁61は弁孔46に吸付けられて該正立時用空気吸込み防止弁62を閉塞することとなり、よって正立時用液体吸込み路を通って容器体内液体が吸上げられることとなるものである。
【００３０】
図９は第２実施形態を示す。該実施形態は、主として既述第１実施形態における、倒立時用液体吸込み筒21の一部と弁付き筒41の一部とを変更したものであり、非変更部分については同一符号を付設して説明を省略する。倒立時用液体吸込み筒21は、その上面を閉塞する頂板22の後部に立筒25a を貫設し、該主筒上部を主筒６の下部内へ水密に嵌合させている。又弁付き筒41は、その上面を閉塞する第１横壁42の後部を開口し、該開口周縁から起立させた第１縦筒44上部を上記立筒25a の下部外面へ水密に嵌合させている。又弁座45の後部内面から第１縦筒44の下部前面へ、上後方への傾斜縦条49を付設している。更に弁座45上縁の左右両側からは側板30a,30a を起立させて、第１実施形態における側板30,30 に代えている。
【００３１】
該実施形態の場合は弁室31を、弁付き部材41が有する弁座45と、第１縦筒44の前面と、側板30a,30a と、倒立時用液体吸込み筒21が有する頂板22の前部下面と、ガイド板29とで形成することとなる。
【００３２】
作用については第１実施形態の場合と同じであり、よって説明は省略する。
【００３３】
【発明の効果】
本発明は既述構成とするもので、頂板22から垂下筒23を垂設する倒立時用液体吸込み筒21の中間部内に弁付き筒41を、かつ下部内に吸上げパイプ取付筒51を、それぞれ嵌合させて、その倒立時用液体吸込み筒21上部を従来のトリガー式液体噴出器の基筒部３内へ、かつ上記垂下筒23内へ主筒６下部をそれぞれ嵌合させるから、それ等三部材をコンパクトにかつ一体的に嵌合させることが出来ると共に、それ等を基筒部に対して確実かつ安全に取付けできる。又上記弁付き筒41と吸上げパイプ取付筒51とが有する第１横壁42と第２横壁52とにそれぞれ貫設した第１縦筒44と第２縦筒54とを介して、第２縦筒から垂設した吸上げパイプ56と主筒６とを連通させて正立時用液体吸込み路を形成するから、その形成が容易である。
【００３４】
倒立時用液体吸込み筒21前部に穿設した倒立時用液体吸込み口27下縁に近接する弁付き筒第１横壁前部に下部小径のテーパ状弁座45を設け、該弁座上へ載置させた玉弁61の上部前面へ下端を近接させて、斜上後方への傾斜面28を形成したから、又玉弁61の側部上方を囲んで弁室31とし、該弁室前面を上記傾斜面で形成したから、射出筒前部を下方へ向けて容器体をほぼ水平とした状態でも玉弁61は上記傾斜面下端に接して弁座45に近接する位置に停止することとなり、よって該容器体水平状態においても倒立時用空気吸込み防止弁62は作用することとなり、該容器体水平状態での液体噴出が可能である。
【００３５】
請求項２の場合のように第１縦筒44上部を立筒25a の下部外面へ嵌合させると共に、弁座45の後部内面から第１縦筒44の下部前面へ、上方向への傾斜縦条49を付設することで、容器体倒立時における弁室上部内への玉弁61の移動が容易かつ確実とすることが出来る。
【００３６】
請求項３記載のように、倒立時用液体吸込み口27を、容器体口頸部外面へ嵌合させた装着筒２の下端面よりも上方の口頸部部分内へ位置させることで、容器体内液体が極めて少なくなった後でも容器倒立状態での液体噴出が可能である。
【００３７】
請求項４記載のように、基筒部３の頂壁５前部にシリンダ内と連通する外気供給路16の出口孔としての第１透孔16a を穿設し、該第１透孔下面へ、基筒部頂壁から起立する短筒26に嵌合させた弁部材75の弁板74を圧接させて閉塞することで、容器倒立使用時にその第１透孔16a からの液洩れを防止でき、又その第１透孔から基筒部３の上部内へ入った外気が、容器体内へ流入するための溝32を、倒立時用液体吸込み口27から周方向へ離れた液体吸込み筒21の上部外面ないし、該外面と対向する基筒部３の内面に縦設したから、容器体倒立使用時にその溝を通り気泡となって容器体液面上方へ上昇する外気が、上記倒立時用液体吸込み口27から吸込みされる液体と共にシリンダ内へ吸込みされることを防ぐことが出来る。
【００３８】
請求項５のように、容器体胴部の下方を大きく前方へ張出しさせ、かつ吸上げパイプを下前方へ屈曲させ、その下端を容器体底壁の前端部上へ位置させることで、容器体内液体をほぼ使い尽くすことが出来る。

In addition, when a negative pressure is generated in the container body due to the liquid ejection, the first through hole 16a drilled in the front portion of the top wall of the base tube portion 3 and the second through hole 16b drilled in the cylinder bottom portion are connected to each other. When the outside air supply path 16 is retracted by the plunger 13 by the trigger pulling operation, the second through hole is opened so that the outside air communicates with the inside of the base tube portion 3 through the cylinder, and the negative pressure To solve the problem.
[0012]
In the present invention, a space is left in the upper portion of the base tube portion 3 and the inverted liquid suction tube 21 is suspended from the base tube portion. In addition, a valved cylinder, which will be described later, and a suction pipe mounting cylinder are fitted into the liquid suction cylinder.
[0013]

From above, a guide plate 29 having a rear surface inclined obliquely forward to the front inner surface of the base cylinder portion above is vertically provided, and the upper portion of the plate extends to the inside of the short cylinder and the front surface of the hanging cylinder 23. is doing. Further, side plates 30 and 30 stand obliquely upward and rearward from the left and right sides of the liquid suction port 27, and a valve chamber 31 is formed by these side plates and the front surface of the hanging cylinder 23 behind the side plates. .
[0015]
As shown in FIG. 6, the valved cylinder 41 hangs down the first outer cylinder 43 from the outer periphery of the first horizontal wall 42, opens the rear of the first horizontal wall, and hangs down the first vertical cylinder 44 from the periphery of the opening. In addition, a lower small diameter tapered valve seat 45 is provided at the front of the lateral wall, and the lower end of the valve seat serves as a valve hole 46. As shown in the drawing, the upper end portion of the first outer cylinder at the front upper portion of the valve seat is preferably notched 47 so as not to close the liquid suction port 27 for the above-described inversion. The front end of the lower end of the first vertical cylinder 44 is also cut out and opened.
[0016]
As shown in FIG. 7, the suction pipe mounting cylinder 51 hangs down the second outer cylinder 53 from the outer periphery of the second horizontal wall 52, opens the rear part of the second horizontal wall 52, and opens the second vertical cylinder from the periphery of the opening. 54 is drooping. In the illustrated example, the upper surface of the front portion of the second horizontal wall is a concave surface 55, and a gap is provided between the lower surface of the first horizontal wall portion having the valve seat 45 described above. The upper part of the suction pipe 56 is closely fitted into the second vertical cylinder 54.
[0017]
In the illustrated example, the lower part of the fitting cylinder 25 of the inverted liquid suction cylinder 21 is fitted into the upper part of the first vertical cylinder 44 of the valved cylinder 41, and the lower end surface of the first vertical cylinder and the suction pipe mounting cylinder 51 are fitted. The upper end surface of the second vertical cylinder 54 is in watertight contact with the suction pipe 56, the second vertical cylinder 54, the first vertical cylinder 44, the fitting cylinder 25, and the main cylinder 6. The liquid suction path is formed.
[0018]
A ball valve 61 is placed on the tapered valve seat 45 described above, and the ball valve and the valve hole 46 at the lower end of the valve seat form an air suction prevention valve 62 for upright. The lower end of the inclined surface 28 of the inverted liquid suction cylinder 21 is provided close to the upper front surface of the ball valve 61.
[0019]
Further, on the outer surface of the short cylinder 26 described above, a valve member 75 having a valve plate 74 attached to the upper ends of a plurality of elastic thread pieces 73 standing at equal intervals from the upper end surface of the cylinder 72 as shown in FIG. The cylinder body is fitted to the outer surface of the short cylinder 26, and the valve plate 74 is pressed against the lower surface of the first through hole 16a formed in the front portion of the top wall of the base cylinder portion 3 by the elasticity of the elastic threaded piece 73, and is closed. Let These valve plate and the first through hole form an outside air intake valve 76, and when the pressure in the container body becomes negative, the outside air intake valve is opened and the air that has entered the upper portion of the base cylinder portion 3 is As shown in FIG. 5, the liquid suction port 27 is provided so as to be separated from the inverted liquid suction port 27 in the circumferential direction and enter the container body through a groove 32 provided vertically on the upper outer surface of the liquid suction tube 21. Of course, the groove may be formed in the inner surface of the base tube portion 3.
[0020]
The container body 1 described above is for the upright state formed by a lower end formed by a lower inner portion extending largely forward with respect to the central axis of the body portion, and the suction pipe 56 bent downward from the middle portion. The liquid suction port is close to the front end of the bottom wall of the container body.
[0021]
In the illustrated example, the upright liquid suction path is formed by the suction pipe 56, the second vertical cylinder 54, the first vertical cylinder 44, the fitting cylinder 25, and the main cylinder 6. For example, the first vertical cylinder 44 is It is also possible to extend upward and directly fit into the lower part of the main cylinder to form the liquid suction path for the upright state. Further, in the illustrated example, the liquid suction path for the inverted state includes the liquid suction port 27 for the inverted position, the valve chamber 31, the valve hole 46, the gap between the first and second lateral walls 42 and 52, and the first vertical The opening 48 is formed by an opening 48 formed in the cylinder 44. The opening 48 is formed by extending the second vertical cylinder 54 of the suction pipe mounting cylinder upward instead of drilling the first vertical cylinder 44, Of course, the extension cylinder portion may be perforated.
[0022]
As shown in FIGS. 1 and 2, the liquid suction port 27 for inversion is positioned in the mouth and neck portion above the lower end surface of the mounting cylinder 2 to be fitted to the outer surface of the container body neck.
[0023]
It should be noted that the formation of the outside air intake valve 76 described above may be provided if necessary, and the forward overhang of the lower part of the container body and the forward bending of the suction pipe 56 are the same.
[0024]
In the above configuration, when an appropriate amount of liquid is placed in the container body and a trigger operation is performed in the container body upright state, the liquid suction port 27 for inversion is opened above the liquid surface in the container body. Since the upright air suction prevention valve 62 is provided in the middle of the inverted liquid suction path to 48, the air above the liquid level does not enter the cylinder through the inverted liquid suction path. The liquid in the container passes through the upright liquid suction passage and is sucked into the cylinder through the suction valve 14 as in the case of a normal trigger type liquid ejection container. It passes through the discharge valve 15 at high pressure and is ejected from the nozzle cylinder at the front end of the injection cylinder.
[0025]
Next, when the container body is inverted, the lower end of the suction pipe 56 is exposed above the liquid level, the liquid suction port 27 for inversion is submerged in water, and the ball valve 61 moves above the valve chamber 31 by its own weight, Therefore, the upright air intake prevention valve 62 is opened.
[0026]
When a negative pressure is generated in the cylinder 7 by the trigger operation in this state, the liquid that has entered the upright liquid suction path through the opening 48 through the inverted liquid suction path is sucked into the cylinder 7, and the plunger The discharge valve 15 is opened due to the high pressure in the cylinder by retreating, passes through the injection cylinder, and is ejected from the nozzle cylinder. Although the lower end of the suction pipe 56 is exposed above the liquid level, the liquid contained in the pipe communicates with the liquid in the container through the liquid suction passage for inversion. The surface and the liquid level of the liquid in the container are substantially equal to each other, so that air does not enter the cylinder through the pipe when the liquid is sucked into the cylinder. When the liquid is reduced and the inside of the container becomes negative pressure during the inverted use, the outside air supply passage 16 and the outside air intake valve 76 are opened by retreating the plunger 13, and the outside air thus entered into the upper portion of the base cylinder portion 3 is It passes through a groove 32 provided vertically on the upper outer surface of the liquid suction cylinder 21 for inversion, rises into the water as a bubble, is discharged above the liquid level, and the negative pressure state is eliminated. Since the groove 32 is provided away from the inverted liquid suction port 27 in the circumferential direction, the bubbles are not sucked together with the liquid sucked from the inverted liquid suction port 27.
[0027]
In the present invention, liquid can be ejected even when the injection cylinder 8 is facing downward and the container body is substantially horizontal.
[0028]
That is, when doing so, the liquid suction port 27 for inversion is opened downward (sideward in the upright state), and the ball valve 61 of the air suction prevention valve 62 for the upright state leaves the valve seat 45. Then, the upper front surface is brought into contact with the lower end of the inclined surface 28 on the front surface of the valve chamber 31 and stopped. At this time, the lower front projecting portion of the container body portion projects downward in the horizontal state, and the lower end of the suction pipe 56 is also located in the lower projecting portion. If the liquid level is above the inverted liquid suction port 27, both of these liquid suction ports are in water, so that the liquid can be ejected by a trigger operation.
[0029]
If the liquid is further reduced in the horizontal state of the container body and the liquid level in the container is positioned below the inverted liquid suction port 27, the suction port 27 is removed when the pressure in the cylinder becomes negative. Since the ball valve 61 is in contact with the inclined surface 28 and close to the valve seat 45 as described above, the ball valve 61 is placed in the valve hole 46 simultaneously with the air suction. By being sucked, the upright air suction prevention valve 62 is closed, so that the liquid in the container is sucked up through the upright liquid suction passage.
[0030]
FIG. 9 shows a second embodiment. In this embodiment, a part of the inverted liquid suction cylinder 21 and a part of the valved cylinder 41 in the first embodiment are mainly changed, and the same reference numerals are assigned to the non-change parts. The description is omitted. The inverted liquid suction cylinder 21 has a vertical cylinder 25a penetrating the rear portion of the top plate 22 that closes the upper surface thereof, and the upper part of the main cylinder is fitted into the lower part of the main cylinder 6 in a watertight manner. The valved cylinder 41 is formed by opening the rear portion of the first horizontal wall 42 that closes the upper surface thereof, and fitting the upper part of the first vertical cylinder 44 raised from the peripheral edge of the opening to the lower outer surface of the vertical cylinder 25a in a watertight manner. Yes. In addition, an inclined vertical strip 49 is attached from the rear inner surface of the valve seat 45 to the lower front surface of the first vertical cylinder 44 in the upward and backward direction. Further, side plates 30a, 30a are erected from both the left and right sides of the upper edge of the valve seat 45 to replace the side plates 30, 30 in the first embodiment.
[0031]
In this embodiment, the valve chamber 31 is provided in front of the valve seat 45 of the valved member 41, the front surface of the first vertical cylinder 44, the side plates 30a and 30a, and the top plate 22 of the liquid suction cylinder 21 for inversion. It is formed by the lower surface of the part and the guide plate 29.
[0032]
The operation is the same as in the case of the first embodiment, and thus description thereof is omitted.
[0033]
【The invention's effect】
The present invention is configured as described above, a valved cylinder 41 in the middle portion of the inverted liquid suction cylinder 21 that hangs the hanging cylinder 23 from the top plate 22, and a suction pipe mounting cylinder 51 in the lower part, The upper part of the liquid suction cylinder 21 for inversion is fitted into the base cylinder part 3 of the conventional trigger type liquid ejector and the lower part of the main cylinder 6 is fitted into the drooping cylinder 23, respectively. The three members can be fitted compactly and integrally, and they can be securely and safely attached to the base tube portion. Further, a second vertical cylinder 44 and a second vertical cylinder 54 are provided through the first horizontal wall 42 and the second horizontal wall 52 of the valved cylinder 41 and the suction pipe mounting cylinder 51, respectively. Since the suction pipe 56 suspended from the cylinder and the main cylinder 6 communicate with each other to form the upright liquid suction path, the formation is easy.
[0034]
A tapered valve seat 45 having a small diameter is provided on the front side of the first horizontal wall of the valve-equipped cylinder near the lower edge of the inverted liquid suction port 27 formed in the front part of the inverted liquid suction cylinder 21 and onto the valve seat. Since the lower end is brought close to the upper front surface of the mounted ball valve 61 and the inclined surface 28 is formed obliquely upward and backward, the valve chamber 31 is surrounded by surrounding the upper side of the ball valve 61, and the front surface of the valve chamber. The ball valve 61 stops at a position close to the valve seat 45 in contact with the lower end of the inclined surface even when the container body is substantially horizontal with the front of the injection cylinder facing downward. Therefore, the air suction prevention valve 62 for inversion works even in the horizontal state of the container body, and the liquid can be ejected in the horizontal state of the container body.
[0035]
As in the case of claim 2, the upper part of the first vertical cylinder 44 is fitted to the lower outer surface of the vertical cylinder 25a, and the vertical vertical inclination from the rear inner surface of the valve seat 45 to the lower front surface of the first vertical cylinder 44 is performed. By attaching the strip 49, the ball valve 61 can be easily and reliably moved into the upper part of the valve chamber when the container body is inverted.
[0036]
By positioning the inverted liquid suction port 27 in the mouth and neck portion above the lower end surface of the mounting cylinder 2 fitted to the outer surface of the neck portion of the container body, as described in claim 3. Even after the liquid in the body is extremely low, the liquid can be ejected in the inverted state of the container.
[0037]
According to a fourth aspect of the present invention, the first through hole 16a as the outlet hole of the outside air supply passage 16 communicating with the inside of the cylinder is formed in the front portion of the top wall 5 of the base tube portion 3, and the lower surface of the first through hole is formed. By closing the valve plate 74 of the valve member 75 fitted to the short cylinder 26 rising from the top wall of the base cylinder portion, the liquid leakage from the first through hole 16a can be prevented when the container is inverted. In addition, the groove 32 for allowing the outside air that has entered the upper part of the base cylinder part 3 from the first through hole to flow into the container body is formed in the liquid suction cylinder 21 that is separated from the liquid suction port 27 for inversion in the circumferential direction. Since it is vertically provided on the upper outer surface or the inner surface of the base cylinder portion 3 facing the outer surface, the outside air that rises upward as the liquid level of the container body through the groove when the container body is inverted is sucked into the liquid for inversion. It is possible to prevent the liquid sucked from the mouth 27 from being sucked into the cylinder.
[0038]
As in claim 5, the lower part of the container body is greatly extended forward, the suction pipe is bent downward and forward, and the lower end thereof is positioned on the front end of the container body bottom wall. The liquid can be almost used up.
