本案は泡放出用のポンプ容器に係る。 The present invention relates to a pump container for foam discharge.
【０００２】[0002]
例えば国際公開番号WO92/08657号の泡放出用ポンプ容器が知られている。該容 器は、下部を液体用の小径シリンダに、かつ上部を外気用の大径シリンダに、そ れぞれ形成したシリンダ部材を、大径シリンダ上端面を閉塞板で密閉させて容器 体内へ垂設すると共に、それ等両シリンダ内へ嵌合させた小径および大径の筒状 ピストンから小径および大径のステムを、小径ステム上部を大径ステム内へ嵌着 させかつ大径ステムを上記開閉板に貫通させて起立し、該ステム上端にノズル付 き押下げヘッドを付設して上方付勢された作動部材を設け、上記小径シリンダ下 端と大径筒状ピストンの頂板とには液体用および外気用吸入弁を、小径ステム上 端部内には液体吐出弁を、大小両ステム間には空気流出路を、更に小径ステム上 端からノズル孔までの流出路部分には発泡部材を、それぞれ設けて、作動部材の 上下動で大小両シリンダ内へ吸込みした外気と容器体内液体とを発泡部材通過に より混合発泡させてノズルから放出可能としたものである。 For example, a pump container for foam discharge of International Publication No. WO92 / 08657 is known. In this container, the lower part is a small diameter cylinder for liquids, the upper part is a large diameter cylinder for outside air, and the formed cylinder members are sealed inside the container by closing the upper end surface of the large diameter cylinder with a closing plate. Install the small diameter and large diameter stems from the small diameter and large diameter cylindrical pistons that are vertically installed and fit into both cylinders, and fit the upper portion of the small diameter stem into the large diameter stem. It is erected by penetrating through the open / close plate, and a push-down head with nozzle is attached to the upper end of the stem to provide an actuating member that is urged upward, and the lower end of the small-diameter cylinder and the top plate of the large-diameter cylindrical piston are liquid. And an outside air intake valve, a liquid discharge valve in the upper end of the small diameter stem, an air outflow path between the large and small stems, and a foam member in the outflow path from the upper end of the small diameter stem to the nozzle hole. Provided respectively, and by the vertical movement of the operating member The outside air sucked into both the large and small cylinders and the liquid inside the container are mixed and foamed by passing through the foaming member and can be discharged from the nozzle.
【０００３】[0003]
上記泡放出用のポンプ容器は、大小両ステム間に設けた空気流入路が常時開放 状態にあるため、泡放出操作の後に小径ステム上端よりも上方の吐出路内に残っ た液体が大径シリンダ内へ入り、そのため該大径シリンダの容量が徐々に狭少化 することとなるものであった。従来はその全体を使い棄て容器としていたため、 容器体内液体を使い終わるまでに大径シリンダ内に貯る液体量は僅かであり、そ のためさほどの支障を来すことはなかったが、上記シリンダおよび作動部材が形 成するポンプ部を再使用する場合は、大径シリンダ内に貯った液体量が更に増大 することとなり、すると大径シリンダ内に吸込まれる外気の量が少なくなり、そ のため液体と空気との混合比が変化して適正な発泡が得られなくなる欠点があっ た。 In the above foam discharge pump container, the air inflow path provided between the large and small stems is always open, so the liquid remaining in the discharge path above the upper end of the small diameter stem after the foam discharge operation is in the large cylinder. Therefore, the capacity of the large-diameter cylinder was gradually narrowed. In the past, the entire container was discarded and used as a container, so the amount of liquid stored in the large-diameter cylinder was small until the liquid inside the container was used up, which did not cause any problems. When the pump part formed by the cylinder and the operating member is reused, the amount of liquid stored in the large diameter cylinder further increases, which reduces the amount of outside air sucked into the large diameter cylinder. As a result, the mixing ratio of liquid and air changes, and proper foaming cannot be obtained.
【０００４】 本案は大径ステム下端から大径筒状ピストンを切離し、かつ作動部材押下げ時 には大径ステム下端が大径筒状ピストンを押下げると共に作動部材上昇時には小 径ステムに付設したフランジが大径筒状ピストンを押上げるようにすることで、 作動部材下降時にだけ上記空気流出路が開き、該流出路内に貯っていた液体を押 戻して大径シリンダ内の高圧空気が小径シリンダから押出された液体と混合し発 泡放出するよう設けることで、上記欠点を除去するものである。According to the present invention, the large-diameter tubular piston is separated from the lower end of the large-diameter stem, and the lower end of the large-diameter stem pushes down the large-diameter cylindrical piston when the operating member is pushed down and is attached to the small-diameter stem when the operating member rises. By making the flange push up the large-diameter cylindrical piston, the air outflow passage opens only when the operating member descends, and the liquid stored in the outflow passage is pushed back and high-pressure air in the large-diameter cylinder is released. The above-mentioned drawbacks are eliminated by being provided so as to mix with the liquid extruded from the small diameter cylinder and emit bubbles.

The small-diameter and large-diameter cylindrical pistons fitted inside the small-diameter and large-diameter stems are fitted into the large-diameter stem with the upper part of the small-diameter stem inserted, and the large-diameter stem penetrates the opening / closing plate to stand up. A lowering head with a nozzle is attached to the upper end of the stem to provide an actuating member that is biased upward, and liquid and external intake valves are provided at the lower end of the small diameter cylinder and the top plate of the large diameter cylindrical piston, and a small diameter stem. A liquid discharge valve is provided in the upper end, an air inflow path is provided between the large and small stems, and a foaming member is provided in the outflow path from the upper end of the small diameter stem to the nozzle hole. foam In the pump container that can be discharged, the large-diameter cylindrical piston 40 is separated from the lower end of the large-diameter stem 29 so that the lower part of the large-diameter stem is the large-inner diameter part 33, and the inner diameter of the large-diameter cylindrical piston is small. An upper end of the cylinder that expands upward and outward is slidably pressed against the inner wall surface of the large inner diameter section 33 by attaching an insertion cylinder 44 that penetrates the stem so that it can move up and down. At the upper limit of the cylindrical piston 40, a flange 26 that contacts the lower surface of the insertion tube 44 and blocks the inlet to the air outflow passage 25 is provided around the small diameter stem 23, and the flange 26 is inserted by pushing down the operating member 20. After the inlet was opened apart from the lower surface, the lower end of the large-diameter stem 29 was provided so as to come into contact with the large-diameter cylindrical piston 40 so as to be able to be pushed down.

図１の状態で、小径ステム23のフランジ26は、大径筒状ピストン40の挿通筒44 下面へ気密に接し、よって上記フランジ26は、該フランジ上方の小径ステム部分 外面に縦設した空気流出路25下端と大径シリンダ室内とを連通する流入口を気密 に遮断している。該図１の状態から図２のように、作動部材20を押下げると、大 径筒状ピストン40は大径シリンダ５内壁面に圧接したまま停止しているが、小径 ステム23は下降するため、フランジ26は挿通筒44の下端面を離れて大径シリンダ 室内と空気流出路25とが連通する。更に作動部材が下降することで大径ステム29 下端が大径筒状ピストン40上面に接し、該ピストンを下方へ押下げる。該押下げ で大径シリンダ室内は高圧化し、外気用吸入弁46が閉じ、その室内高圧空気は空 気流出路25を通過する。一方小径シリンダ４内液体も吐出弁22を通過し、上記空 気と共に発泡部材32通過により混合し、発泡してノズル30から放出される。作動 部材20が下限に達した後、押下げを解放することで、作動部材は上昇し、上記大 径ステム29は大径筒状ピストン40から離れ、又フランジ26は挿通筒44下面に接し て空気流出路25への流入口を遮断したまま大径筒状ピストン40を押上げることと なり、大径シリンダ室内の負圧化で外気吸入弁46が、又小径シリンダ４内の負圧 化で液体吸入弁10が、それぞれ開いてそれ等内部へ空気および容器体内液体を吸 込む。 In the state shown in FIG. 1, the flange 26 of the small-diameter stem 23 is in airtight contact with the lower surface of the insertion tube 44 of the large-diameter cylindrical piston 40, so that the flange 26 has an air outflow provided vertically on the outer surface of the small-diameter stem portion above the flange. The inflow port that connects the lower end of the passage 25 and the large-diameter cylinder chamber is hermetically closed. When the actuating member 20 is pushed down from the state of FIG. 1 as shown in FIG. 2, the large-diameter cylindrical piston 40 stops while being in pressure contact with the inner wall surface of the large-diameter cylinder 5, but the small-diameter stem 23 descends. The flange 26 leaves the lower end surface of the insertion tube 44 to connect the large diameter cylinder chamber and the air outflow passage 25. When the operating member is further lowered, the lower end of the large-diameter stem 29 comes into contact with the upper surface of the large-diameter cylindrical piston 40 and pushes the piston downward. By pushing down, the pressure in the large-diameter cylinder chamber is increased, the intake valve 46 for the outside air is closed, and the high pressure air in the chamber passes through the air outflow passage 25. On the other hand, the liquid in the small diameter cylinder 4 also passes through the discharge valve 22, is mixed with the above-mentioned air by passing through the foaming member 32, is foamed, and is discharged from the nozzle 30. After the operating member 20 reaches the lower limit, the pushing member is released to raise the operating member, the large-diameter stem 29 is separated from the large-diameter cylindrical piston 40, and the flange 26 contacts the lower surface of the insertion tube 44. The large-diameter cylindrical piston 40 is pushed up while the inlet to the air outflow passage 25 is blocked, and the outside air intake valve 46 is changed to a negative pressure inside the large-diameter cylinder chamber and the negative pressure inside the small-diameter cylinder 4 is changed. The liquid suction valves 10 are opened to suck air and liquid in the container into them.

It will be mixed with the above-mentioned high-pressure air and discharged as bubbles, and therefore will not enter the large diameter cylinder chamber.
