Description

【０００１】
【発明の属する技術分野】
本発明は泡や液体等を噴出する縦型ポンプ式噴出容器に関する。
【０００２】
【従来の技術】
この種の泡噴出容器は、例えば特開平７−３１５４０８号に示すように公知であり、これを図２を参照しながら説明する。
１は口頸部２を起立する容器体である。
３は口頸部の上端面へ、上端外面に付設した外向きフランジ４を載置させて容器体内へ垂下する空気用の大径シリンダで、該シリンダ下部は下方小径のテーパ状部とし、かつ上面を上向き段部５とした内向きフランジ状部を介して小内径筒部６を垂下し、さらに第２の下方小径テーパ状部を介して吸上げパイプ嵌合筒７を垂下し、該筒内に上端部を嵌着させて吸上げパイプ８を容器体内底部まで垂下する。上記第２の下方小径テーパ状部内面は弁座とし、玉弁を載置して吸込み弁９とする。
また、上記外向きフランジ４下方のシリンダ壁上部には外気吸入孔１０を穿設している。
【０００３】
１５は口頸部外面へ螺合させた装着筒で、該装着筒上端に付設した内向きフランジ状頂板１６と口頸部上端面との間で、パッキンと共に上記大径シリンダ３の外向きフランジ４を挟持する。
【０００４】
１７は大径シリンダ上端部へ嵌合させたガイド環で、頂板外周部から垂下した内外筒間に大径シリンダ上端部を嵌着させ、又頂板内周から雌ねじ筒１８を垂下する。
【０００５】
２０は上記大径シリンダ３内からスプリング２１の上方付勢により押下げ可能にガイド環１７内を通って起立する作動部材で、外周部を下外方へ下降させ、かつ外周部に複数割溝を有する外向きフランジ２２を下部外面に付設した、ステム兼用の小径シリンダ２３を起立し、該小径シリンダ上部をノズル２４付き押下げヘッド２５から垂下する嵌合筒２５ａ内へ嵌着させ、また、小径シリンダ上端部内へ水密に嵌合させた短筒２７の上端開口面を発泡用網２８で閉塞している。
【０００６】
さらに、短筒２７の直ぐ下方の小径シリンダ内面には、下部小径のテーパ状弁座を設け、該弁座上へ逆円錐状の頭部２９を載置して、その下端から脚棒３０を垂下する吐出弁体３１を設け、上記弁座と頭部とで吐出弁３２を形成している。該吐出弁と発泡用網２８との間が混合室３３を形成する。該混合室と嵌合筒２５ａ下端との間には、後述第１空気路と連通させる第２空気路３４を設ける。該第２空気路は嵌合筒２５ａ内へ嵌合させた小径シリンダ上部外面に穿設した第１縦溝３５と小径シリンダ上端部に穿設した透孔３６と短筒２７外面に穿設した第２縦溝３７とで形成している。
【０００７】
嵌合筒２５ａ下方の小径シリンダ２３部分外面へは大径シリンダ内壁面へ嵌合させた大径筒状ピストン３８から起立する筒管３９を、小ストロークだけ上下動自在に嵌合させる。その筒管３９上端部は小内径部４０とし、その小内径下端面へ小径シリンダ２３外面に付設した係合突条２３ａが係合し、かつ大径筒状ピストン３８上面がガイド環１７の雌ねじ筒１８下端面に係合するまで、大径シリンダ内に内装されたスプリング２１上端が大径筒状ピストン下面に係合する小径シリンダ２３下部の外向きフランジ２２下面を押上げすることで作動部材の上限が定まるよう設けている。
該作動部材上限位置において筒管３９上端面と嵌合筒２５ａ下端面との間には小間隙が形成されており、該状態から作動部材２０を押下げすると筒管に対して小径シリンダ２３が下降することで筒管上端面へ嵌合筒２５ａ下端面が気密に接し、以後筒管３９付き大径筒状ピストン３８が共に下降する。この下降の際に作動部材下方の大径シリンダ内部分が形成する空気室３ａ内空気を第２空気路３４を通って混合室内へ噴出させるための第１空気路４１を、小径シリンダ２３外面と筒管３９内面との間に縦設した溝で形成する。
【０００８】
４５は起立筒部材で、大径シリンダ３の小内径筒部６内へ下端筒部を水密に嵌合させ、かつ該嵌合部分上端に付設した外向きフランジ４６を、作動部材押上げ用スプリング２１の下端と上向き段部５とで挟持させ、上部を小径シリンダ２３内へ嵌合させて起立し、上端筒部を小径筒状ピストン４７としている。また、吐出弁体の脚棒３０を起立筒部材４５内へ挿入し、該脚棒下部に付設した係合突条を小径筒状ピストン４７の下端内面に設けた小内径部下端面に係合させている。
【０００９】
嵌合筒２５ａの下部外面は雄ねじ筒として、作動部材押下げ状態でガイド環１７の雌ねじ筒１８内へ螺合可能とし、このとき脚棒３０下端は吸込み弁９の玉弁上面に接するよう設けている。
【００１０】
泡を噴出させるには押下げヘッド２５を押し下げればよく、すると嵌合筒２５ａの下端面が筒管３９上端面に当接して第１空気路４１と第２空気路３４とを連通させると共に、小径シリンダ２３の下降により小径筒状ピストン４７が相対的に上昇して、小径シリンダ内の液体が混合室３３内へ流入すると共に、大径筒状ピストン３８の下降により圧縮された、空気室３ａ内の空気が第１及び第２空気路４１、３４を介して混合室３３内へ流入することにより混合室内に泡が形成される。この泡は発泡用網２８を通過する際に均一化されて混合室３３から流出する。
【００１１】
泡噴出により容器体内と空気室３ａ内とが負圧化するため、外気が、筒管３９外面と雌ねじ筒１８内面との間隙から流入し、外気吸入孔１０を通って容器体内へ流入すると共に、嵌合筒２５ａ下面と筒管３９上面との間隙からも流入し、第２及び第１空気路３４、４１を通って空気室３ａ内へ流入する。
【００１２】
【発明が解決しようとする課題】
シャワーを浴びながら泡噴出ポンプ容器を使用する場合、上記公知例では雌ねじ筒１８内面と筒管３９外面との間隙が常時シャワー水にさらされているため、この間隙からシャワー水が大径シリンダ３内へ入るおそれがあるが、押下げヘッド２５が上限に位置するときは大径筒状ピストン３８が外気吸入孔１０を閉塞しているため、大径シリンダ３内に入ったシャワー水が外気吸入孔１０から容器体１内へ流入することがないが、押下げヘッド押下げ時には下降して外気吸入孔１０を開放するため、この外気吸入孔からシャワー水が容器体内へ流入可能となるが、このことは容器体内液体を劣化させる等の原因ともなっていた。
【００１３】
そこで、請求項１記載の発明は、押下げヘッドの外周壁からシール筒を垂下して、内向きフランジ状頂板のフランジ孔と押下げヘッドとの間隙をシャワー水から遮断することにより、容器体内への水の浸入を防止しようとし、併せてカバー部材を設けることにより、外観向上を図ると共に、シール筒の取付けをより強固にしようとするものである。
【００１４】
請求項２記載の発明は、上記請求項１記載の発明が有する解決課題を有するほか、外気導入用の連通路をシール筒に形成することにより構成を簡素にすると共に、案内筒を設けることによりシール筒の外側を覆うカバー部材を省略可能にしようとするものである。
【００１６】
【課題を解決するための手段】
第１の手段として、周壁上端部から起立する容器体１の口頸部２外面へ装着筒１５を嵌合させ、かつ該装着筒の上端に内向きフランジ状頂板１６を付設したキャップ状部材を形成して、容器体内へ垂設させた縦型ポンプから上記フランジ状頂板１６のフランジ孔に挿通させてステム２３を上方付勢状態で起立し、該ステム上端へ嵌合させた押下げヘッド２５の上下動で容器体内液体を吸上げ、押下げヘッドが有するノズル２４から噴出可能に設けた、縦型ポンプ式の噴出容器において、上記押下げヘッド２５の頂壁外周から外周壁５０を垂設し、上記外周壁の下部内面へ水密に、かつ抜出し不能に嵌合させた小径筒部６１下端から外向きフランジ状壁部６２を介して大径筒部６３を垂設して、該大径筒部の下部を上記装着筒１５の上部へ係合部を介して係合させた軟材質の弾性変形自在なシール筒６０を設け、上記シール筒を、押下げヘッドの押し下げで、大径筒部６３の上部が下内方に弾性変形可能に形成し、かつ、上記装着筒１５の下部外面から突設した複数の連結片１５ｄを介して装着筒下部外方を大径リング１５ｅで囲成し、該大径リング外面へ下部周壁を嵌合させて起立する、頂部開口のドラム状筒７２で上記シール筒大径筒部６３を囲成すると共に、該ドラム状筒内面から複数の係合板７３を突設して、該係合板下面をシール筒の外向きフランジ６５上面へ係合させたカバー部材７０を設けた。
【００１７】
第２の手段として、第１の手段を有すると共に、上記内向きフランジ状頂板１６の内周縁から、押下げヘッド外面との間に通気間隙をおいて案内筒１５ｃを起立し、
上記内向きフランジ状頂板１６上面から嵌合筒１５ａを起立して、該嵌合筒外面へ上記シール筒６０下部を嵌合させ、かつこれら両筒の嵌合部分に連通路６４、１５ｂを形成して、これら両連通路を上記通気間隙を介して容器体内へ連通させた。
【００１８】
第３の手段として、第１又は第２の手段を有すると共に、上記連通路６４を、シール筒下端に付設した外向きフランジ６５下面に形成した。
【００１９】
【発明の実施の形態】
以下、本発明に係る縦型ポンプ式の噴出容器の実施形態を図面を参照しながら説明する。なお、上記公知例と同一部分については同一符号を付して説明を省略する。
本実施形態ではガイド環１７を省略すると共に、内向きフランジ状頂板１６内周から作動部材２０の上限を定める係合筒１８ａを垂下して、該係合筒の下端面へ大径筒状ピストン３８上面を係合させる。
【００２０】
５０は押下げヘッド２５の外周壁で、嵌合筒２５ａ外方の押下げヘッド頂壁部分外周から嵌合筒２５ａと筒管３９上部とを囲成して垂下する。
なお、外周壁５０下端部外面は下方大径のテーパ状部を介して大外径部５１に形成する。
【００２１】
６０は軟材質の弾性変形自在なシール筒で、小径筒部６１を大外径部５１内面へ凹凸の係合手段を介して抜出し不能に、かつ水密に嵌合させると共に、小径筒部６１下端から、外方へ湾曲させた外向きフランジ状壁部６２を介して大径筒部６３を垂設し、かつ該大径筒部の下端部を装着筒１５の上部へ係合部を介して係合させる。
【００２２】
上記係合部は、請求項２記載のように内向きフランジ状頂板１６の外周部上面から起立した嵌合筒１５ａで形成し、該嵌合筒外面へシール筒６０の下端部を嵌合させる。
これらシール筒６０と嵌合筒１５ａとにはそれぞれ第１連通路６４と第２連通路１５ｂとをそれぞれ複数形成して両連通路を互いに連通させる。
シール筒６０の下端外面には、請求項３記載のように外向きフランジ６５を付設するのが好ましく、この場合には第１連通路６４を外向きフランジ下面に放射状に形成する。
なお、上記ではシール筒６０を嵌合筒１５ａへ嵌合させているが、これに限らず装着筒１５の上部外面へ嵌合させることも可能である。
【００２３】
また、請求項２記載のように内向きフランジ状頂板の内周縁から案内筒１５ｃを起立する。この案内筒は第１及び第２連通路６４、１５ｂから水が浸入した場合に、この水が内向きフランジ状頂板１６のフランジ孔と筒管３９との間隙から大径シリンダ３内へ入らないようにするためのもので、その上端部はシール筒６０の小径筒部６１内に達する。
なお、案内筒１５ｃ内面と筒管３９外面との間には空気が流入可能な通気間隙が形成されるようにする。また、案内筒１５ｃと小径筒部６１との間に間隙が形成されるようにして、小径筒部６１が下方へ弾性変形する際に案内筒１５ｃと干渉しないようにする。
【００２４】
さらに、上記装着筒１５の下部外面から突設した複数の連結片１５ｄを介して装着筒下部外方を大径リング１５ｅで囲成する。７０はカバー部材で、大径リング１５ｅ外面へ凹凸の係合手段を介して抜出し不能に嵌合させた筒部から上向き段部７１を介して頂部開口のドラム状筒７２を起立し、該ドラム状筒で小径筒部６１より下方のシール筒６０部分を囲成する。また、ドラム状筒７２内面から複数の三角形状の係合板７３を突設して、これら係合板下面をシール筒の外向きフランジ６５上面へ係合させて、これら係合板７３をシール筒６０の大径筒部６３外面へ近接させる。
【００２５】
８０はキャップで、頂板外周から垂下する周壁８１下端部をカバー部材７０外面へ着脱自在に嵌合させて、その周壁下端を上向き段部７１へ載置させる。
【００２６】
なお、上記では本発明を、液体噴出用の小径シリンダ２３、空気圧縮用の大径シリンダ３及び液体と空気との混合室３３を有する泡噴出容器に適用した例について説明したが、空気圧縮用の大径シリンダ３を有しない液体噴出容器についても適用できること勿論である。
【００２７】
次に本実施形態の作用について説明する。
シール筒６０は軟材質の弾性変形自在な素材から形成されるため、押下げヘッド２５の押下げが可能であり、キャップ８０を外して押下げヘッドを押し下げるとシール筒上部は下内方に弾性変形する。これと反対に押下げヘッドが上昇するとシール筒６０は元の形状に復帰する。
このようなシール筒６０が案内筒１５ｃと筒管３９との通気間隙を覆っているため、この通気間隙内へのシャワー水の浸入は防止される。
一方、押下げヘッド外周壁５０の下端部外面とカバー部材７０の頂部開口内面との間隙からがバー部材７０内に浸入したシャワー水は大径リング１５ｅの連結片１５ｄ間を通ってカバー部材７０外へと流出する。
【００２８】
泡等の噴出後、押下げヘッド２５が上昇して容器体内が負圧化すると、外気がカバー部材７０と装着筒１５との下端間から流入し、大径リングの連結片１５ｄ間から第１及び第２連通路６４、１５ｄを通って案内筒１５ｃと筒管３９との通気間隙内へ入り、さらに大径シリンダ３から外気吸入孔１０を介して容器体１内へ流入する。
なお、カバー部材７０を使用しない場合、シャワー水が第１及び第２連通路６４、１５ｂからシール筒６０内へ流入することがあるが、案内筒１５ｃが設けられているため容器体内への浸入は防止される。
【００２９】
【発明の効果】
請求項１乃至３記載の発明は、押下げヘッドの外周壁からシール筒を垂下したので、シャワー水等の容器体内への浸入が防止される。又請求項１記載の発明は、カバー部材を設けたので、外観が向上すると共に、該カバー筒に係合板を形成したため、シール部材の取付けがより強固になる。請求項２記載の発明は、外気導入用の連通路をシール筒に形成するため、簡素な構成で容器体負圧化時における容器体内への外気導入が確保される。また、案内筒を設けたので、カバー部材を使用しない場合でも容器体内への水の浸入が防止される。

BACKGROUND OF THE INVENTION
The present invention relates to a vertical pump-type ejection container that ejects bubbles, liquids, and the like.
[0002]
[Prior art]
This type of bubble ejection container is known, for example, as shown in JP-A-7-315408, and will be described with reference to FIG.
Reference numeral 1 denotes a container body that erects the mouth-and-neck portion 2.
3 is a large-diameter cylinder for air that is placed on the upper end surface of the mouth-and-neck portion and has an outward flange 4 attached to the outer surface of the upper end, and hangs down into the container body. A small-diameter cylindrical portion 6 is suspended via an inward flange-shaped portion whose upper surface is an upward stepped portion 5, and a suction pipe fitting cylinder 7 is suspended via a second lower-diameter tapered portion. The upper end portion is fitted inside, and the suction pipe 8 is suspended to the bottom of the container body. The inner surface of the second lower small diameter tapered portion is a valve seat, and a ball valve is placed on the suction valve 9.
An outside air suction hole 10 is formed in the upper part of the cylinder wall below the outward flange 4.
[0003]
Reference numeral 15 denotes a mounting cylinder screwed to the outer surface of the mouth and neck portion. Between the inward flange-like top plate 16 attached to the upper end of the mounting tube and the upper end surface of the mouth and neck portion, the outward flange of the large-diameter cylinder 3 together with the packing. 4 is pinched.
[0004]
A guide ring 17 is fitted to the upper end of the large diameter cylinder. The upper end of the large diameter cylinder is fitted between the inner and outer cylinders suspended from the outer periphery of the top plate, and the female screw cylinder 18 is suspended from the inner periphery of the top plate.
[0005]
Reference numeral 20 denotes an operating member which stands up through the guide ring 17 so as to be able to be pushed down by the upward biasing of the spring 21 from within the large-diameter cylinder 3, and lowers the outer peripheral portion downward and outward, and a plurality of split grooves are formed in the outer peripheral portion. A small-diameter cylinder 23 serving as a stem, which has an outward flange 22 attached to the lower outer surface, and is fitted into a fitting cylinder 25a that hangs down from a pressing head 25 with a nozzle 24. The upper end opening surface of the short cylinder 27 fitted in a watertight manner into the upper end portion of the small-diameter cylinder is closed with a foaming net 28.
[0006]
Further, a tapered valve seat having a lower diameter is provided on the inner surface of the small diameter cylinder just below the short cylinder 27, and an inverted conical head 29 is placed on the valve seat. A dripping discharge valve body 31 is provided, and a discharge valve 32 is formed by the valve seat and the head. A mixing chamber 33 is formed between the discharge valve and the foaming net 28. A second air passage 34 is provided between the mixing chamber and the lower end of the fitting cylinder 25a so as to communicate with the first air passage described later. The second air passage is formed in the outer surface of the first vertical groove 35 formed in the upper outer surface of the small-diameter cylinder fitted into the fitting cylinder 25a, the through hole 36 formed in the upper end portion of the small-diameter cylinder, and the outer surface of the short cylinder 27. The second vertical groove 37 is formed.
[0007]
A cylindrical tube 39 rising from a large-diameter cylindrical piston 38 fitted to the inner wall surface of the large-diameter cylinder is fitted to the outer surface of the small-diameter cylinder 23 below the fitting cylinder 25a so as to be movable up and down by a small stroke. The upper end portion of the cylindrical tube 39 is a small inner diameter portion 40, the engagement protrusion 23 a attached to the outer surface of the small diameter cylinder 23 is engaged with the lower end surface of the small inner diameter, and the upper surface of the large diameter cylindrical piston 38 is the female thread of the guide ring 17. The upper end of the spring 21 housed in the large diameter cylinder pushes up the lower surface of the outward flange 22 below the small diameter cylinder 23 engaged with the lower surface of the large diameter cylindrical piston until the lower end surface of the cylinder 18 is engaged. The upper limit is established.
A small gap is formed between the upper end surface of the tubular tube 39 and the lower end surface of the fitting tube 25a at the upper limit position of the operating member. When the operating member 20 is pushed down from this state, the small diameter cylinder 23 is moved with respect to the tubular tube. By lowering, the lower end surface of the fitting tube 25a comes into airtight contact with the upper end surface of the tube, and thereafter, the large-diameter cylindrical piston 38 with the tube 39 is moved down together. The first air passage 41 for causing the air in the air chamber 3a formed by the inner portion of the large-diameter cylinder below the operating member to be blown into the mixing chamber through the second air passage 34 at the time of the lowering is formed on the outer surface of the small-diameter cylinder 23. It is formed by a groove provided vertically between the inner surface of the tube tube 39.
[0008]
Reference numeral 45 denotes an upright cylinder member, which has a lower end cylinder portion fitted into the small inner diameter cylinder portion 6 of the large diameter cylinder 3 in a watertight manner, and an outward flange 46 attached to the upper end of the engagement portion. 21 is sandwiched between the lower end 21 and the upward stepped portion 5, the upper portion is fitted into the small diameter cylinder 23, and the upper end cylindrical portion is a small diameter cylindrical piston 47. In addition, the leg rod 30 of the discharge valve body is inserted into the upright cylindrical member 45, and the engagement protrusion provided on the lower portion of the leg rod is engaged with the lower end surface of the small inner diameter portion provided on the lower end inner surface of the small diameter cylindrical piston 47. ing.
[0009]
The lower outer surface of the fitting cylinder 25a is a male screw cylinder that can be screwed into the female screw cylinder 18 of the guide ring 17 when the operating member is depressed. At this time, the lower end of the leg bar 30 is provided so as to be in contact with the upper surface of the ball valve of the suction valve 9 ing.
[0010]
In order to eject the bubbles, the push-down head 25 may be pushed down, and the lower end surface of the fitting tube 25a abuts on the upper end surface of the tube tube 39 to connect the first air passage 41 and the second air passage 34. The small-diameter cylindrical piston 47 is relatively raised by the lowering of the small-diameter cylinder 23, and the liquid in the small-diameter cylinder flows into the mixing chamber 33 and is compressed by the lowering of the large-diameter cylindrical piston 38. Bubbles are formed in the mixing chamber by the air in 3a flowing into the mixing chamber 33 through the first and second air passages 41 and. The bubbles are made uniform when passing through the foaming net 28 and flow out of the mixing chamber 33.
[0011]
Since the bubble and the inside of the air chamber 3a become negative pressure due to the bubble ejection, the outside air flows from the gap between the outer surface of the tube tube 39 and the inner surface of the female screw cylinder 18 and flows into the container body through the outside air suction hole 10. Then, it flows also from the gap between the lower surface of the fitting tube 25a and the upper surface of the tube tube 39, and flows into the air chamber 3a through the second and first air passages 34 and 41.
[0012]
[Problems to be solved by the invention]
In the case of using a foam jet pump container while taking a shower, in the above known example, the gap between the inner surface of the female screw cylinder 18 and the outer surface of the cylinder pipe 39 is always exposed to shower water. Although there is a risk of entering the inside, the large-diameter cylindrical piston 38 closes the outside air suction hole 10 when the pressing head 25 is located at the upper limit. Although it does not flow into the container body 1 from the hole 10, it is lowered when the pressing head is pressed down to open the outside air suction hole 10, so that shower water can flow into the container body from this outside air suction hole. This has been a cause of deterioration of the liquid in the container.
[0013]
In view of this, the invention according to claim 1 suspends the seal tube from the outer peripheral wall of the pressing head and shuts off the gap between the flange hole of the inwardly flanged top plate and the pressing head from shower water. In order to prevent the intrusion of water into the water and to provide a cover member together, it is intended to improve the appearance and further strengthen the attachment of the seal cylinder.
[0014]
The invention described in claim 2 has the problem to be solved by the invention described in claim 1 above, and by simplifying the configuration by forming a communication path for introducing outside air in the seal cylinder, and by providing a guide cylinder The cover member that covers the outer side of the seal cylinder is to be omitted.
