Description

本発明はポンプ容器に関する。   The present invention relates to a pump container.

ポンプ容器として、容器体の口頸部にポンプを装着したものであって、該ポンプは、容器体内に垂下させるシリンダを備え、また、シリンダを摺動するピストンと連繋したステムの上端に噴出ヘッドを固定した作動部材を備え、この作動部材の上下動によりヘッドの噴出口より収納液を噴出する如く構成したものが知られている。或いは上記ポンプとして起泡構造を備え、作動部材の上下動により空気と液とを混合させた混合液を起泡させ且つヘッドの噴出口より泡状に噴出する如く構成した泡噴出用のものが知られている。   As a pump container, a pump is mounted on the mouth and neck of the container body. The pump includes a cylinder that hangs down in the container body, and an ejection head at the upper end of a stem that is connected to a piston that slides the cylinder. There is known a configuration in which a storage liquid is ejected from an ejection port of a head by the vertical movement of the actuation member. Alternatively, the above-mentioned pump is provided with a foaming structure, and a foam jetting device configured to foam a liquid mixture obtained by mixing air and liquid by the vertical movement of the operating member and to jet the foamed liquid from the jet outlet of the head. Are known.

これらは運搬，保管時の取り扱い等により、例えば、横積みされる等により、容器体内液がシリンダに設けた外気導入孔よりシリンダ内に浸入し、それが作動部材のピストン上方に溜まってしまう。従って、作動部材の係止を外して上方へ突出した際に溜まった液が装着キャップのステムが上下動する開口より吹き出してしまう不都合を生じる。そこで、従来は例えば外気導入孔の外方を塞ぐ弁板を設けてこの様な不都合を解消している（例えば、特許文献１参照）。   Due to handling during transportation and storage, for example, when they are stacked horizontally, the liquid in the container enters the cylinder from the outside air introduction hole provided in the cylinder and accumulates above the piston of the operating member. Therefore, there is a problem that the liquid accumulated when the operating member is unlocked and protrudes upward is blown out from the opening in which the stem of the mounting cap moves up and down. Therefore, conventionally, for example, a valve plate that closes the outside of the outside air introduction hole is provided to eliminate such inconvenience (for example, see Patent Document 1).

上記特許文献１のポンプ容器は、上部を大径の空気用シリンダに、下部を小径の液用シリンダにそれぞれ形成し、かつ空気用シリンダ上部に容器体内への外気導入弁を設けたシリンダ部材を、空気用シリンダ上端を蓋板で閉塞させて容器体内へ垂設固定するとともに、上記両シリンダ内へ嵌合させた大小両径ピストンから大小両径ステムを、小径ステム上部を大径ステム内へ嵌着させ且つ大径ステムを蓋板に貫通させて起立し、大径ステム上端にノズル付き押し下げヘッドを付設して、上方付勢された作動部材を設け、付勢に抗して押し下げられた状態で押し下げヘッド一部を蓋板一部へ螺合可能に設けたものである。   The pump container disclosed in Patent Document 1 includes a cylinder member in which an upper part is formed in a large-diameter air cylinder and a lower part is formed in a small-diameter liquid cylinder, and an air-air introduction valve into the container body is provided on the upper part of the air cylinder. The upper end of the air cylinder is closed with a lid plate and fixed in the container body. The large and small diameter pistons are fitted into the cylinders and the small and large diameter stems are inserted into the large diameter stem. The large-diameter stem was inserted into the lid plate and stood up, and a push-down head with a nozzle was attached to the upper end of the large-diameter stem, and an upwardly biased operating member was provided, which was pushed down against the bias. In this state, a part of the push-down head is provided so as to be able to be screwed to a part of the lid plate.

尚、該螺合は、例えば作動部材が上方へ起立する輸送時の包装が嵩張ることとなるため、その作動部材を下限まで押し下げてその包装を小型化するためで、使用の際は作動部材の上下動で液用シリンダ内へ液体が、又空気用シリンダ内へ外気がそれぞれに設けた吸込み弁を通って流入し、又、それ等両シリンダ内の液体及び空気が、液体は小径ステム上端の吐出弁を通って、又空気は大小両ステム間に設けた通路を通って、更に大径ステム上端上方の吐出路部分内へ嵌着させた発泡部材を通過することで混合し、発泡してノズルから放出する様に設けたものである。容器体内の液体減少による負圧化は、空気シリンダ上部の外気導入弁を通って流出した空気が解消する。   Note that the screwing is, for example, because the packaging at the time of transportation in which the operating member stands upward is bulky, so that the operating member is pushed down to the lower limit to reduce the size of the packaging. Up and down movement, liquid flows into the liquid cylinder, and outside air flows into the air cylinder through the respective suction valves. The liquid and air in both the cylinders are at the top of the small-diameter stem. Through the discharge valve, the air passes through a passage provided between the large and small stems, and further passes through a foam member fitted into the discharge path portion above the upper end of the large-diameter stem. It is provided to discharge from the nozzle. The negative pressure due to the decrease of the liquid in the container body eliminates the air flowing out through the outside air introduction valve at the top of the air cylinder.

上記外気導入弁は、空気用シリンダ上部に穿設した弁孔と、空気用シリンダ部分の上部外面へ嵌合させた弁筒体から垂下して弁孔を閉塞する舌弁とで形成するが、容器全体をコンパクトに形成するためには、空気用シリンダ外壁面と、空気用シリンダを有するシリンダ部材を垂設する容器体口頸部の内壁面との間の隙間を狭小化することとなり、そのようにその隙間を狭小化すると、シリンダ部材を容器体内へ垂下させる際に上記舌片及び弁筒体が容器体口頸部に当たって悪影響を生じたり、舌片と口頸部内壁面との間に隙間が弁開閉上充分でなかったりする等欠点を来すこととなるものであった。 The outside air introduction valve is formed by a valve hole drilled in the upper part of the air cylinder and a tongue valve that hangs down from the valve cylinder fitted to the upper outer surface of the air cylinder part and closes the valve hole. In order to form the entire container compactly, the gap between the outer wall surface of the air cylinder and the inner wall surface of the container body neck that suspends the cylinder member having the air cylinder will be narrowed. If the gap is narrowed as described above, the tongue piece and the valve cylinder hit the container body neck when the cylinder member is suspended into the container body, and there is an adverse effect between the tongue piece and the inner wall surface of the mouth neck. There was a drawback that the gap was not sufficient for opening and closing the valve.

また、上記容器では、外気導入孔は、弁体により外面より常時閉塞されているため、単なる透孔と比較すると容器体内への空気の導入は阻害され易く、また、この弊害は円滑且つ迅速な容器体内への空気の導入が特に必要な、容器体内から起泡のために空気をポンプ内に導入するタイプの泡噴出用のポンプ容器においてはより顕著である。   Further, in the above container, since the outside air introduction hole is always closed from the outer surface by the valve body, the introduction of air into the container body is easily inhibited compared to a simple through hole, and this adverse effect is smooth and quick. This is more conspicuous in a pump container for foam ejection in which air is introduced into a pump for foaming from the container body, which particularly requires introduction of air into the container body.

この様な点を考慮して、本出願人は上記不都合を解消した優れたポンプ容器を提案し、すでに特許されている（特許文献２参照）。   In consideration of such points, the present applicant has proposed an excellent pump container that has solved the above inconvenience and has already been patented (see Patent Document 2).

上記特許文献２のポンプ容器は、シリンダ上面を閉塞する蓋板のステム突出窓孔内周に上下摺動可能に且つステムとの間に小間隙をあけて嵌合させた摺動筒を有するとともに、該筒外周下部よりシリンダ内周に摺動可能に嵌合させたシール用筒を延設してなる孔開閉部材を設け、該孔開閉部材は、作動部材の押し下げ係止時に作動部材によりシール用筒による外気導入孔閉塞位置に下降させて固定させるとともに、作動部材の最上昇時には作動部材により外気導入孔開口位置に上昇させて係止させる如く構成している。
米国特許出願公開第Ｗ０９２／０８６５７号明細書 特許第３３６０９１７号公報 The pump container disclosed in Patent Document 2 has a sliding cylinder that is slidable up and down on the inner periphery of the stem projecting window hole of the lid plate that closes the upper surface of the cylinder and is fitted with a small gap between the stem and the stem. A hole opening / closing member is provided by extending a sealing cylinder slidably fitted to the cylinder inner periphery from the lower outer periphery of the cylinder, and the hole opening / closing member is sealed by the operating member when the operating member is held down. The cylinder is lowered and fixed to the outside air introduction hole blocking position by the cylinder, and is configured to be raised and locked by the operation member to the outside air introduction hole opening position when the operation member is raised to the maximum.

上記孔開閉部材を設けたポンプ容器にあって、孔開閉部材の孔閉塞時にはシール用筒による充分な密閉性を要し、また、孔開閉部材の移動時にはシール用筒がシリンダを摺動するためより容易な摺動性を要求される。充分な密閉性を得るためにはシリンダと密接摺動するシール用筒がよりシリンダ側に圧接力の高い状態が好ましく，また、上記容易な摺動性を求める場合には圧接力は小さい方が好ましいという相反する条件が必要となる。   In the pump container provided with the hole opening / closing member, when the hole opening / closing member is closed, the sealing cylinder needs to be sufficiently sealed, and when the hole opening / closing member moves, the sealing cylinder slides on the cylinder. Easier slidability is required. In order to obtain sufficient sealing performance, it is preferable that the sealing cylinder that slides in close contact with the cylinder has a higher pressure contact force on the cylinder side. The contradictory condition of being preferable is required.

本発明はこの様な点を考慮して、上記孔開閉部材を設けたポンプ容器を更に改良し、シール用筒の充分な密接シール性と容易な摺動性を備えてより円滑な作動を行えるとともに、外気の導入・遮断の切り換えをより確実に行え、また、収納液のシリンダ内への漏出防止を図れ、しかも従来容器のもつ特性を充分発揮出きる優れたポンプ容器を提案するものである。   In consideration of such a point, the present invention further improves the pump container provided with the hole opening and closing member, and can perform smoother operation with sufficient tight sealing performance and easy sliding performance of the sealing cylinder. At the same time, it is possible to switch between introduction and shut-off of outside air more reliably, to prevent leakage of stored liquid into the cylinder, and to propose an excellent pump container that can fully demonstrate the characteristics of conventional containers. .

本請求項１発明のポンプ容器は、上記課題を解決するため、容器体Ａ内に垂下した外気導入孔４付きのシリンダ５を備えるとともに、該シリンダ内周を摺動するピストン６と連繋させたステム７の上端に噴出ヘッド８を固定し、且つ、上方付勢状態で押し下げ可能に設けた作動部材９を備え、該作動部材９の上下動により上記噴出ヘッドの噴出口10より上記容器体内の液を噴出する如く構成したポンプ容器であって、上記作動部材が最下降の係止状態に移行する際に押し下げられて上記外気導入孔の閉塞状態に移行するとともに、上記作動部材が最上昇状態に移行する際に押し上げられて上記外気導入孔開放状態に移行する可動弁体61を設け、該可動弁体61の外気導入孔４を開閉するシール部62が、上記外気導入孔４上下の上記シリンダ５内周に密接する環状の上部圧接部62a 及び下部圧接部62b を備えた筒状をなし、且つ、上記可動弁体61の最上昇位置で下部圧接部62b のみが上記シリンダ５に密接する如く構成したことを特徴とするポンプ容器として構成した。   In order to solve the above problems, the pump container according to the first aspect of the present invention includes a cylinder 5 with an outside air introduction hole 4 suspended in the container body A, and is connected to a piston 6 that slides on the inner periphery of the cylinder. An ejecting head 8 is fixed to the upper end of the stem 7 and is provided with an operating member 9 provided so as to be able to be pushed down in an upward biased state, and the actuating member 9 moves up and down from the outlet 10 of the ejecting head. A pump container configured to eject liquid, and is pushed down when the operating member shifts to the lowest locking state and shifts to the closed state of the outside air introduction hole, and the operating member is in the highest rising state. The movable valve body 61 that is pushed up when shifting to the outside air introduction hole is provided, and the seal portion 62 that opens and closes the outside air introduction hole 4 of the movable valve body 61 is provided above and below the outside air introduction hole 4. Inner circumference of cylinder 5 A cylindrical shape having an annular upper pressure contact portion 62a and a lower pressure contact portion 62b which are in close contact with each other, and only the lower pressure contact portion 62b in close contact with the cylinder 5 at the highest position of the movable valve body 61 is configured. Configured as a featured pump container.

本請求項２発明のポンプ容器は、外気導入孔４付きの上記シリンダ５としての大径の空気用シリンダ19と、該空気用シリンダ下方に連設した小径の液用シリンダ21を備え、上記作動部材９が、上記空気用シリンダ19内を摺動する上記ピストン６としての空気用ピストン27及び上記液用シリンダ21内を摺動する液用ピストン28を連繋させたステム７を備えるとともに、上記液用シリンダ21からの液と空気用シリンダ19からの空気を合流させて起泡させる起泡機構を備えた泡噴出用である請求項１記載のポンプ容器として構成した。   The pump container according to the second aspect of the present invention includes a large-diameter air cylinder 19 as the cylinder 5 with the outside air introduction hole 4 and a small-diameter liquid cylinder 21 provided continuously below the air cylinder. The member 9 includes a stem 7 in which an air piston 27 as the piston 6 sliding in the air cylinder 19 and a liquid piston 28 sliding in the liquid cylinder 21 are connected, and the liquid 2. The pump container according to claim 1, wherein the pump container is for foam ejection, which is provided with a foaming mechanism for causing the liquid from the cylinder for air 21 and the air from the cylinder for air 19 to foam together.

また、本請求項３発明のポンプ容器は、上記可動弁体61が、上記外気導入孔４の閉塞状態である最下降位置で停止するストッパーを設けてなる請求項１又は請求項２のいずれかに記載のポンプ容器として構成した。   Further, in the pump container according to the third aspect of the present invention, the movable valve body 61 is provided with a stopper which stops at the lowest position where the outside air introduction hole 4 is closed. It was constituted as a pump container described in 1.

また、本請求項４発明のポンプ容器は、上記上部圧接部62a 及び下部圧接部62b が、それぞれ環状突条で構成されてなる請求項１乃至請求項３のいずれかに記載のポンプ容器として構成した。   The pump container according to claim 4 is configured as the pump container according to any one of claims 1 to 3, wherein each of the upper pressure contact portion 62a and the lower pressure contact portion 62b is formed of an annular protrusion. did.

本発明のポンプ容器は、作動部材を押し下げ係止した状態では容器体Ａ内への外気導入孔４は可動弁体61により密に閉塞されていて、例えば運搬，保管の際の横積みによる液のシリンダ内への浸入等を確実に防止できるものである。また、可動弁体61は外気導入孔４上下のシリンダ５内周に密接する環状の上部圧接部62a 及び下部圧接部62b を備えた筒状をなし、また、可動弁体61の最上昇位置で下部圧接部62b のみがシリンダ５に密接する如く構成しているので、上部圧接部62a が摺動する範囲を極力短くでき、充分なシール性を発揮できるにも拘わらず、摺動性にも優れたものとなる。摺動性が悪いと可動弁体61が部分的に弾性的変形を来して適正な上下動を阻害される虞があるが、それを防止できる。   In the pump container of the present invention, the outside air introduction hole 4 into the container body A is closed tightly by the movable valve body 61 in a state where the operation member is pushed down and locked. Can be reliably prevented from entering the cylinder. The movable valve body 61 has a cylindrical shape with an annular upper pressure contact portion 62a and a lower pressure contact portion 62b that are in close contact with the inner circumferences of the cylinders 5 above and below the outside air introduction hole 4, and at the highest position of the movable valve body 61. Since only the lower pressure contact portion 62b is configured to be in close contact with the cylinder 5, the range in which the upper pressure contact portion 62a slides can be shortened as much as possible, and although it exhibits a sufficient sealing performance, it has excellent sliding properties. It will be. If the slidability is poor, the movable valve body 61 may be partially elastically deformed to hinder proper vertical movement, but this can be prevented.

また、外気導入孔４の閉塞状態である最下降位置で停止するストッパーを設けたものにあっては、作動部材に対してフリーな状態の可動弁体61が、所定下降位置より行き過ぎる等の不都合を解消できるものである。更に上部圧接部62a 及び下部圧接部62b をそれぞれ環状突条で構成した場合には更なる摺動性の良さを発揮できる。   Further, in the case of providing a stopper that stops at the lowest lowered position in which the outside air introduction hole 4 is closed, the movable valve body 61 that is free with respect to the actuating member is inconvenient such that the movable valve body 61 goes too far from the predetermined lowered position. Can be eliminated. Further, when the upper pressure contact portion 62a and the lower pressure contact portion 62b are each formed of an annular protrusion, it is possible to further improve the slidability.

本発明では、上記外気導入孔４を開閉する可動弁体61を設けている。この可動弁体61は、合成樹脂等により形成することができ、作動部材９が最下降の係止状態に移行する際に押し下げて外気導入孔４の閉塞状態に移行させるとともに、作動部材９が最上昇状態に移行する際に押し上げて外気導入孔４開放状態に移行させる如く構成したものである。従って、作動部材９を押し下げ係止した状態では、保管，運搬等に横積みしても、或いは使用開始後に不用意に容器を倒しても容器体内の液がシリンダ５内に浸入するのを確実に防止できるものである。   In the present invention, a movable valve element 61 that opens and closes the outside air introduction hole 4 is provided. The movable valve body 61 can be formed of a synthetic resin or the like, and is pushed down when the operating member 9 shifts to the lowermost locking state to shift to the closed state of the outside air introduction hole 4. It is configured to push up and shift to the open state of the outside air introduction hole 4 when shifting to the highest state. Therefore, in the state where the operating member 9 is pushed down and locked, it is ensured that the liquid in the container enters the cylinder 5 even if it is stacked horizontally for storage, transportation, etc., or the container is inadvertently tilted after the start of use. Can be prevented.

具体的には、空気用ピストン27上方の空気用シリンダ19にシール部62を上下摺動可能に嵌合させて装着したものであり、作動部材９による押し下げ及び押し上げ手段は種々の形態を採用できる。図示例では、シール部62の内側より押圧壁63を内方へ延設し、押し下げる際にはこの押圧壁63の上面内周縁部を、噴出ヘッド８の連結筒32に突設した上記押圧リブ44により押し下げる如く構成し、また、押し上げる際には、上記空気用ピストンの連結壁40上面により押圧壁63の下面内周縁部を押し上げる如く構成している。上記押圧リブ44はその押圧面である下面が可動弁体61と所定距離離間しており、作動部材９が最上昇位置に或る状態から最下降の係止状態に移行した際に、可動弁体61のシール部62が外気導入孔４を閉塞する位置に移行する如く調整している。   Specifically, the seal portion 62 is fitted to the air cylinder 19 above the air piston 27 so as to be slidable up and down, and the push-down and push-up means by the actuating member 9 can adopt various forms. . In the illustrated example, the pressing wall 63 extends inward from the inner side of the seal portion 62, and when pressing down, the inner peripheral edge of the upper surface of the pressing wall 63 projects from the connecting cylinder 32 of the ejection head 8. It is configured to be pushed down by 44, and when pushed up, the lower inner peripheral edge of the pressing wall 63 is pushed up by the upper surface of the connecting wall 40 of the air piston. The pressing rib 44 has a lower surface, which is a pressing surface, separated from the movable valve body 61 by a predetermined distance, and the movable valve 9 is moved when the operating member 9 shifts from a certain state to the most lowered position. Adjustment is made so that the seal portion 62 of the body 61 moves to a position where the outside air introduction hole 4 is closed.

上記押圧壁63は、内周縁部を装着キャップ11の上記案内筒15内方へ突設した異形環状板状形態のもので、具体的には、装着キャップ11の頂板14裏面より垂設した係止筒64を回避する如く下方へ陥没した凹陥部63a を備えたドーナツ板状をなし、この凹陥部63a の内側上部に係合突条65を突設している。この係合突条65は上記係止筒64下部に突設した係止突条66と係合し、両者により可動弁体61のそれ以上の下降を防止するストッパーの役割を果たす。   The pressing wall 63 has a deformed annular plate shape with an inner peripheral edge projecting inwardly into the guide tube 15 of the mounting cap 11. Specifically, the pressing wall 63 is suspended from the back surface of the top plate 14 of the mounting cap 11. A donut plate shape having a recessed portion 63a recessed downward so as to avoid the stop cylinder 64 is formed, and an engaging ridge 65 is protruded on the inner upper portion of the recessed portion 63a. The engaging ridge 65 engages with a locking ridge 66 protruding from the lower portion of the locking cylinder 64, and serves as a stopper that prevents the movable valve body 61 from being further lowered.

また、本発明に於ける可動弁体61は、外気導入孔４を開閉するシール部62が、外気導入孔４上下のシリンダ５内周に密接する環状の上部圧接部62a 及び下部圧接部62b を備えた筒状をなし、可動弁体61の最上昇位置で下部圧接部62b のみがシリンダ５に密接する如く構成している。従って、可動弁体61の最上昇位置からの押し下げ当初は下部圧接部62b のみがシリンダ５を摺動し、次いで外気導入孔４閉塞状態に至る前に上部圧接部62a がシリンダ５を摺動する如く構成している。この状態を現出するためには、図示例の如く、シリンダ５の上端部内径を所定幅大径に形成することにより行えるが、これに限られず、例えば、空気用シリンダ19の上端部を、最上昇位置の可動弁体61の上部圧接部62a が接触しない高さに形成することによっても現出できる。尚、上記上部圧接部62a 及び下部圧接部62b として、図６に示す如く、環状突条形態に構成したものであってもよく、更に摺動性を向上させる。   In the movable valve body 61 according to the present invention, the seal portion 62 that opens and closes the outside air introduction hole 4 has an annular upper pressure contact portion 62a and a lower pressure contact portion 62b that are in close contact with the inner periphery of the cylinder 5 above and below the outside air introduction hole 4. A cylindrical shape is provided, and only the lower pressure contact portion 62b is in close contact with the cylinder 5 at the highest position of the movable valve body 61. Therefore, only the lower pressure contact portion 62b slides on the cylinder 5 at the beginning when the movable valve body 61 is pushed down from the highest position, and then the upper pressure contact portion 62a slides on the cylinder 5 before the outside air introduction hole 4 is closed. It is configured as follows. In order to reveal this state, as shown in the illustrated example, the upper end of the cylinder 5 can be formed to have an inner diameter of a predetermined width and a large diameter. However, the present invention is not limited to this. For example, the upper end of the air cylinder 19 is It can also be achieved by forming the upper pressure contact portion 62a of the movable valve body 61 at the highest position so as not to contact. Note that the upper pressure contact portion 62a and the lower pressure contact portion 62b may be configured in the form of an annular ridge as shown in FIG. 6, and further improve the slidability.

上記の如く構成したポンプ容器を使用するに当たっては、まず、図１の状態から作動部材９を押し下げると、ステム７の下降により棒状弁体45が押し下げられて吸込み弁52が閉じ、また、液用ピストン28が下降して液用シリンダ21内が加圧され、液吐出弁55が開いて液が気・液混合室Ｒ内に排出される。一方、空気用シリンダ19内が空気用ピストン27の下降により加圧され、空気用ピストン27はステム７に対して相対的に上昇し空気吐出弁37が開き通気路ａを介して空気が気・液混合室Ｒ内へ排出される。ここで混合された液と空気がメッシュ57を介して発泡，整泡されて噴出口10より噴出される。続いてその状態から作動部材９の押圧を解除するとコイルスプリング31の付勢力により作動部材９は上昇する。その際液吐出弁55が閉じて液用シリンダ21内は負圧化して吸込み弁52が開き、吸い上げパイプ56を介して容器体Ａ内液が液用シリンダ21内へ吸引される。一方、空気吐出弁37はステム７の上昇で閉じ、空気用ピストン27がそのまま押し上げられるため空気用シリンダ19内も負圧化し、空気供給弁42が開いて空気用シリンダ19内に空気が導入される。   In using the pump container constructed as described above, when the actuating member 9 is pushed down from the state shown in FIG. 1, the rod-like valve body 45 is pushed down by the lowering of the stem 7 and the suction valve 52 is closed. The piston 28 is lowered to pressurize the liquid cylinder 21 and the liquid discharge valve 55 is opened to discharge the liquid into the gas / liquid mixing chamber R. On the other hand, the inside of the air cylinder 19 is pressurized by the lowering of the air piston 27, the air piston 27 rises relative to the stem 7, the air discharge valve 37 opens, and air flows through the air passage a. It is discharged into the liquid mixing chamber R. The liquid and air mixed here are foamed and foamed through the mesh 57 and ejected from the ejection port 10. Subsequently, when the pressing of the actuating member 9 is released from that state, the actuating member 9 is raised by the urging force of the coil spring 31. At this time, the liquid discharge valve 55 is closed, the pressure inside the liquid cylinder 21 is reduced, the suction valve 52 is opened, and the liquid in the container A is sucked into the liquid cylinder 21 through the suction pipe 56. On the other hand, the air discharge valve 37 is closed by the rise of the stem 7, and the air piston 27 is pushed up as it is, so that the air cylinder 19 also becomes negative pressure, the air supply valve 42 is opened, and air is introduced into the air cylinder 19. The

可動弁体61は、図１の作動部材９が最上昇位置にある場合には最上昇位置にあり、この際、外気導入孔４は空気用ピストン27により閉塞されている。作動部材９の押し下げ係止状態は、図１の状態から作動部材９を最下降位置まで押し下げた後、回転させることにより上記係合突部43を装着キャップ11のフランジ16に係止させる。この際可動弁体61は押圧リブ44により、上部圧接部62a 及び下部圧接部62b 間に外気導入孔４が位置するところまで押し下げられ、外気導入孔４が外部と遮断される。可動弁体61の押し下げに当たっては、最初下部圧接部62b のみが摺動して初動が容易であり途中から上部圧接部62a が空気用シリンダ19内面に摺動する。   The movable valve body 61 is in the highest position when the actuating member 9 of FIG. 1 is in the highest position. At this time, the outside air introduction hole 4 is closed by the air piston 27. The operation member 9 is pushed down and locked from the state shown in FIG. 1 by pushing the operation member 9 down to the lowest position and then rotating the engagement member 43 to the flange 16 of the mounting cap 11. At this time, the movable valve body 61 is pushed down by the pressing rib 44 until the outside air introduction hole 4 is located between the upper pressure contact portion 62a and the lower pressure contact portion 62b, and the outside air introduction hole 4 is blocked from the outside. When the movable valve element 61 is pushed down, only the lower pressure contact portion 62b is slid at first and the initial movement is easy, and the upper pressure contact portion 62a slides on the inner surface of the air cylinder 19 from the middle.

また、可動弁体61の押し下げ係止状態から、作動部材９を回転させて上記係合突部43を上記凹部17位置に移行して係合を解除すると、コイルスプリング31の上方付勢力により作動部材９が上昇し、可動弁体61は空気用ピストン27の連結壁40により押し上げられ元の図１の状態となり、この際、空気用ピストン27の摺動部により外気導入孔４が閉塞される。   In addition, when the movable member 61 is pushed and locked, the operating member 9 is rotated to move the engagement protrusion 43 to the position of the recess 17 to release the engagement, and the coil spring 31 is actuated by the upward biasing force. The member 9 is raised, and the movable valve body 61 is pushed up by the connection wall 40 of the air piston 27 to be in the original state of FIG. 1. At this time, the outside air introduction hole 4 is blocked by the sliding portion of the air piston 27. .

また、上記した泡噴出操作中には可動弁体61は作動しないか或いは小さなストロークでの下降及び上昇を行う。即ち、液噴出の際には一般に作動部材９を最下降位置まで押し下げずに上下動させるため押圧リブ44が可動弁体61を押し下げないか、仮に押し下げたとしても僅かに下降する程度となる。従って、この際には外気導入孔４は空気用ピストン27が最上昇位置にくるまでは常に開放しており、液噴出により負圧化した容器体Ａ内に外気が導入される。また、この操作中可動弁体61が外気導入孔４を塞ぐ位置まで押し下げられることがあっても、空気用ピストン27が上昇して塞ぐまでの間に可動弁体61が押し上げられ外気導入孔４は開放状態となり、負圧化した容器体Ａ内へ外気が導入される。   Further, during the above-described bubble ejection operation, the movable valve element 61 does not operate or descends and rises with a small stroke. That is, when the liquid is ejected, the operation member 9 is generally moved up and down without being pushed down to the lowest position, so that the pressing rib 44 does not push down the movable valve body 61, or even if it is pushed down slightly. Accordingly, at this time, the outside air introduction hole 4 is always open until the air piston 27 reaches the highest position, and the outside air is introduced into the container body A that has been made negative pressure by the liquid ejection. Further, even if the movable valve body 61 is pushed down to a position where the outside air introduction hole 4 is closed during this operation, the movable valve body 61 is pushed up and the outside air introduction hole 4 until the air piston 27 rises and closes. Becomes an open state, and the outside air is introduced into the container body A which has become negative pressure.

尚、上記各部材は主として合成樹脂により形成することができ、必要に応じてエラストマー，金属等を併用して形成することができる。   Each of the above members can be mainly formed of a synthetic resin, and can be formed using an elastomer, a metal or the like in combination as necessary.
