A spherical liquid discharge valve 13 is provided on the valve seat 12 so as to be seated and separated. In the stem 10, the space between the lower end of the small diameter portion of the foam member 60 and the upper surface of the valve seat 12 is the gas-liquid mixing chamber 3.

さらに、ステム１０の外周面においては、複数のステム溝１０ａそれぞれの下端が位置する部分に、その全周にわたって突状部１１が突設されている。押下ヘッド２を押下する前の待機状態では、この突状部１１の上面に、押下ヘッド２が上方に付勢された状態で、空気用ピストン４０における内筒４２の下端が当接することにより、空気用シリンダ１５における空気通路５の開口部を塞いで、空気用シリンダ１５の内部と気液混合室３との連通を遮断するようになっている。   Further, on the outer peripheral surface of the stem 10, a protruding portion 11 protrudes from the portion where the lower ends of the plurality of stem grooves 10 a are located over the entire periphery. In the standby state before the pressing head 2 is pressed, the lower end of the inner cylinder 42 of the air piston 40 comes into contact with the upper surface of the protruding portion 11 while the pressing head 2 is urged upward. The opening of the air passage 5 in the air cylinder 15 is closed to block communication between the inside of the air cylinder 15 and the gas-liquid mixing chamber 3.

ここで、図１に示されるように、ノズル筒部２４の先端部には、中空の塗布部材１２０が着脱自在に装着されている。この塗布部材１２０は、ノズル筒部２４の先端部に着脱自在に嵌合された基筒部１２１と、基筒部１２１の先端から該基筒部１２１の延在方向に直交する軸直方向に張り出した円板状の張出板部１２２と、張出板部１２２の外周縁に沿って延在しかつノズル筒部２４の突出方向に沿って突出する突出筒部１２３と、突出筒部１２３に嵌合して該突出筒部１２３を閉塞する円板状の塗布面板部１２４と、を備えている。   Here, as shown in FIG. 1, a hollow application member 120 is detachably attached to the tip of the nozzle tube portion 24. The application member 120 includes a base cylinder part 121 that is detachably fitted to the tip part of the nozzle cylinder part 24, and an axial direction perpendicular to the extending direction of the base cylinder part 121 from the tip of the base cylinder part 121.

張出板部１２２と塗布面板部１２４との間には隙間が設けられ、塗布面板部１２４には、図３および図４に示されるように、ノズル孔２１と連通する吐出孔１２５が、その外周部を除く全域にわたって複数形成されている。また、本実施形態では、塗布部材１２０は吐出器１００の側面視で、装着キャップ３０の天壁部３２の略真上に位置するように、ノズル筒部２４に取り付けられている。
また、前記塗布面板部１２４の裏面（張出板部１２２側を向く面）には、前記基筒部１２１の開口と対向する位置に突部１４０が形成されている。
前記突部１４０の先端部分は、略半円状に形成され、その横断面が十字状となっている。
さらに、前記吐出孔１２５は、前記突部１４０を避けて形成されており、これによって内容物を塗布面板部１２４上に、均等に吐出することができる。
なお、前記突部１４０の形状は、適宜選択可能である。 A gap is provided between the overhanging plate portion 122 and the application surface plate portion 124, and the application surface plate portion 124 has discharge holes 125 communicating with the nozzle holes 21, as shown in FIGS. 3 and 4. A plurality are formed over the entire region excluding the outer peripheral portion. In the present embodiment, the application member 120 is attached to the nozzle cylinder portion 24 so as to be positioned substantially directly above the top wall portion 32 of the mounting cap 30 in a side view of the discharge device 100.
Further, a protrusion 140 is formed on the back surface of the coating surface plate portion 124 (the surface facing the protruding plate portion 122 side) at a position facing the opening of the base tube portion 121.
The tip portion of the protrusion 140 is formed in a substantially semicircular shape, and its cross section is a cross shape.
Further, the discharge holes 125 are formed so as to avoid the protrusions 140, whereby the contents can be discharged evenly onto the coated face plate portion 124.
The shape of the protrusion 140 can be selected as appropriate.

塗布部材１２０および押下ヘッド２は、有頂筒状のヘッドキャップ１３０によって覆われ、ヘッドキャップ１３０は、装着キャップ３０の装着周壁部３３の上部に着脱可能に外嵌されている。図４に示すように、ヘッドキャップ１３０には、塗布部材１２０を収容可能なように塗布部材１２０の形状に沿って張り出した塗布部材収容部１３１が形成されている。   The coating member 120 and the pressing head 2 are covered with a head cap 130 having a top shape, and the head cap 130 is detachably fitted to the upper portion of the mounting peripheral wall portion 33 of the mounting cap 30. As shown in FIG. 4, the head cap 130 is formed with an application member accommodation portion 131 that projects along the shape of the application member 120 so that the application member 120 can be accommodated.

以上のようなポンプ１および押下ヘッド２が備えられる吐出器では、図１および図２を併せて参照し、押下ヘッド２を押下する前の待機状態において、ステム１０の突状部１１の上面に、空気用ピストン４０における内筒４２の下端が当接し、かつ押下ヘッド２の下端と空気用ピストン４０の内筒４２の上端との間に上下方向の隙間Ｓが設けられている。   In the discharge device provided with the pump 1 and the pressing head 2 as described above, referring to FIGS. 1 and 2 together, in the standby state before the pressing head 2 is pressed, the upper surface of the protruding portion 11 of the stem 10 is The lower end of the inner cylinder 42 in the air piston 40 abuts, and a vertical gap S is provided between the lower end of the pressing head 2 and the upper end of the inner cylinder 42 of the air piston 40.

この状態から、先ずヘッドキャップ１３０を取り外して、押下ヘッド２を押し下げると、装着筒部２２が下降し、発泡部材６０、ステム１０、液用ピストン５０も、コイルスプリング４が上下方向に圧縮変形させられつつ下方に移動させられる。この際、空気用ピストン４０は移動せず、この空気用ピストン４０における内筒４２の下端と、ステム１０における突状部１１の上面との間に隙間が形成され、また、空気用ピストン４０における内筒４２の上端縁と装着筒部２２の内面との間の隙間Ｓは小さくなる。これにより、空気通路５を通して空気用シリンダ１５内と気液混合室３内とが連通する。
さらに、液用ピストン５０の下方への移動に伴い、下部弁体１７ｂが下方に移動させられ、この下部弁体１７ｂが液用シリンダ１６の下端開口部に着座して閉塞し、液用ピストン５０の上端部が、弁部材１７の上部弁体１７ａから下方に離反する。 When the head cap 130 is first removed from this state and the press-down head 2 is pushed down, the mounting cylinder portion 22 is lowered, and the coil spring 4 also compresses and deforms the foam member 60, the stem 10, and the liquid piston 50 in the vertical direction. It is moved downward while being pushed. At this time, the air piston 40 does not move, and a gap is formed between the lower end of the inner cylinder 42 of the air piston 40 and the upper surface of the protruding portion 11 of the stem 10. A gap S between the upper end edge of the inner cylinder 42 and the inner surface of the mounting cylinder portion 22 is reduced. As a result, the air cylinder 15 and the gas-liquid mixing chamber 3 communicate with each other through the air passage 5.
Further, with the downward movement of the liquid piston 50, the lower valve body 17b is moved downward, the lower valve body 17b is seated and closed at the lower end opening of the liquid cylinder 16, and the liquid piston 50 is closed. Of the valve member 17 is separated downward from the upper valve body 17a of the valve member 17.

そして、さらに押下ヘッド２を押し下げると、空気用ピストン４０も、弁体４５が空気孔４３を閉塞した状態で下方に移動させられることにより、空気用シリンダ１５内において空気用ピストン４０の下方に位置する下室内の空気が圧縮させられる。これにより、この下室内の空気が、空気用ピストン４０における内筒４２の下端とステム１０の突状部１１との間の隙間から空気通路５内に流入して気液混合室３に移送される。   When the pressing head 2 is further pushed down, the air piston 40 is also moved downward with the valve body 45 closing the air hole 43, so that the air piston 40 is positioned below the air piston 40 in the air cylinder 15. The air in the lower chamber is compressed. Thus, the air in the lower chamber flows into the air passage 5 from the gap between the lower end of the inner cylinder 42 of the air piston 40 and the protruding portion 11 of the stem 10 and is transferred to the gas-liquid mixing chamber 3. The

さらにこの際、弁部材１７の下部弁体１７ｂが液用シリンダ１６の下端開口部を閉塞した状態で、液用ピストン５０が下方移動するので、液用シリンダ１６内の液体が上昇してステム１０内に到達する。そして、液用シリンダ１６内の液圧を、ステム１０の弁座１２に着座している液吐出弁１３に作用させてこの液吐出弁１３を弁座１２から離反させることにより、液用シリンダ１６内の液体を気液混合室３内に移送する。   Further, at this time, since the lower piston 17b of the valve member 17 closes the lower end opening of the liquid cylinder 16, the liquid piston 50 moves downward, so that the liquid in the liquid cylinder 16 rises and the stem 10 Reach inside. Then, the liquid pressure in the liquid cylinder 16 is applied to the liquid discharge valve 13 seated on the valve seat 12 of the stem 10 to separate the liquid discharge valve 13 from the valve seat 12. The liquid inside is transferred into the gas-liquid mixing chamber 3.

上述のようにして、気液混合室３内で液体および空気を合流させ、発泡部材６０を通過させて液体を発泡させた後に、押下ヘッド２のノズル孔２１を通じて泡状の液体（気液混合体（泡体））を吐出させ、さらに塗布部材１２０の吐出孔１２５から吐出させる。
その後、押下ヘッド２の押し下げを解除すると、コイルスプリング４の弾性復元力により押下ヘッド２、ステム１０、このステム１０に連係された空気用ピストン４０および液用ピストン５０が上方付勢状態に戻ることになる。 As described above, after the liquid and air are merged in the gas-liquid mixing chamber 3 and passed through the foaming member 60, the liquid is foamed, and then the foam-like liquid (gas-liquid mixing) is passed through the nozzle hole 21 of the pressing head 2. Body (foam)) is discharged, and is further discharged from the discharge hole 125 of the application member 120.
Thereafter, when the depression of the pressing head 2 is released, the pressing head 2, the stem 10, the air piston 40 and the liquid piston 50 linked to the stem 10 are returned to the upward biased state by the elastic restoring force of the coil spring 4. become.

以上に説明したように、本発明の実施形態では、押下ヘッド２を押下してノズル孔２１に到達した気液混合体（以下、泡体）が、塗布部材１２０の内部を通って複数の吐出孔１２５から吐出され、塗布部材１２５の先端面上に泡体が到達する。そして、この塗布部材１２０の先端面を被塗布面に摺り付けることで、被塗布面に泡体を塗布することができる。
このように、泡体を被塗布面に塗布するに際し、泡体を塗布部材１２０の先端面上に至らせれば、吐出器１ごと移動させて、被塗布面に塗布部材１２０の先端面を擦り付けることができるので、例えば塗布部材をノズル筒部から取り外して塗布する場合に比べて、良好な操作性を具備させることができる。
また、塗布部材１２０がノズル筒部２４に着脱自在に装着されているので、塗布部材１２０やノズル筒部２４に付着した液体や泡体が固化しても、塗布部材１２０をノズル筒部２４から取り外すことで、これらを容易に洗浄することができるので、使い勝手を良好なものにできる。 As described above, in the embodiment of the present invention, the gas-liquid mixture (hereinafter referred to as foam) that has reached the nozzle hole 21 by pressing the pressing head 2 passes through the inside of the application member 120 and discharges a plurality of liquids. The foam is discharged from the hole 125 and the foam reaches the tip surface of the application member 125. And a foam can be apply | coated to a to-be-coated surface by sliding the front end surface of this application member 120 on a to-be-coated surface.
In this way, when the foam is applied to the surface to be coated, if the foam reaches the tip surface of the coating member 120, the foamer 1 is moved together and rubs the tip surface of the coating member 120 against the surface to be coated. Therefore, for example, better operability can be achieved as compared with the case where the application member is removed from the nozzle cylinder and applied.
Further, since the application member 120 is detachably attached to the nozzle cylinder portion 24, the application member 120 can be removed from the nozzle cylinder portion 24 even if the liquid or foam adhered to the application member 120 or the nozzle cylinder portion 24 is solidified. Since they can be easily cleaned by removing them, the usability can be improved.

また、この吐出器１では、ノズル筒部２４が、ステム１０の中心軸に対して交差する方向に延在している。この場合、吐出器１の姿勢を大きく傾けずに被塗布面まで移動させて泡体を塗布することができ、使い勝手をより良好なものにできる。   Further, in this discharge device 1, the nozzle cylinder portion 24 extends in a direction intersecting with the central axis of the stem 10. In this case, it is possible to apply the foam by moving the dispenser 1 to the surface to be applied without greatly inclining the posture, and the usability can be improved.
