以上のように構成されたフォーマポンプ１０は、押下ヘッド１８を押し下げてステム１５を下方に移動させることにより、容器体２内の内容物を移送するとともに空気と混合させ、これらの気液混合体が発泡されてなる泡状の内容物（以下、泡体という）をノズル孔４３から吐出する。   The former pump 10 configured as described above moves the stem 15 downward by depressing the pressing head 18, thereby transferring the contents in the container body 2 and mixing them with air. Foam-like contents formed by foaming (hereinafter referred to as foam) are discharged from the nozzle holes 43.

この吐出容器１の使用時には、装着キャップ１１から規制部材２４を離脱させた後、押下ヘッド１８を下方へ押し下げて、ステム１５および液用ピストン１４を一体的に押し下げる。   When the discharge container 1 is used, after the regulating member 24 is detached from the mounting cap 11, the pressing head 18 is pushed downward to push the stem 15 and the liquid piston 14 together.

このとき、空気用ピストン１６の内筒部３７が下ステム３５の前記摺動部分の外周面上を摺動するとともに、内筒部３７の上端部が上ステム３６の内周面上を摺動することにより、空気用ピストン１６の上下方向の位置が保持される。その結果、下ステム３５のフランジ部３５ａと、空気用ピストン１６の内筒部３７の下端縁と、の間に、前記空気導入路４２と前記下室４０ｂとを連通する図示しない連通隙間が設けられ、下室４０ｂと気液混合室１７とが連通される。またこのとき、弁部材３４も下方に移動させられ、弁部材３４の下部弁体３４ｂが液用シリンダ１３のテーパ部２９に着座して、液用シリンダ１３の下端開口部が閉塞される。   At this time, the inner cylindrical portion 37 of the air piston 16 slides on the outer peripheral surface of the sliding portion of the lower stem 35, and the upper end portion of the inner cylindrical portion 37 slides on the inner peripheral surface of the upper stem 36. Thus, the vertical position of the air piston 16 is maintained. As a result, a communication gap (not shown) that connects the air introduction path 42 and the lower chamber 40b is provided between the flange portion 35a of the lower stem 35 and the lower end edge of the inner cylinder portion 37 of the air piston 16. The lower chamber 40b and the gas-liquid mixing chamber 17 are communicated with each other. At this time, the valve member 34 is also moved downward, the lower valve body 34b of the valve member 34 is seated on the tapered portion 29 of the liquid cylinder 13, and the lower end opening of the liquid cylinder 13 is closed.

上ステム３６の下端縁が、空気用ピストン１６の連結部３９に当接するまで押下ヘッド１８を押し下げると、押下ヘッド１８とともに空気用ピストン１６が下方に移動し、空気用ピストン１６の外筒部３８が、空気用シリンダ１２の周壁部２６の内周面上を、下方に向けて摺動する。   When the pressing head 18 is pushed down until the lower end edge of the upper stem 36 contacts the connecting portion 39 of the air piston 16, the air piston 16 moves downward together with the pressing head 18, and the outer cylinder portion 38 of the air piston 16. However, it slides downward on the inner peripheral surface of the peripheral wall portion 26 of the air cylinder 12.

このとき、空気用ピストン１６の弁筒部４１の外気導入弁４１ａは、連結部３９の下面に密接されたままの状態であり、前記貫通孔は閉塞されている。これにより、下室４０ｂ内の空気が圧縮され、この空気が、前記連通隙間および空気導入路４２を通して気液混合室１７に移送される。またこのとき、液用シリンダ１３の下端開口部が閉塞された状態で、付勢部材３３を圧縮変形させつつ、液用ピストン１４を下方に移動させて、弁部材３４の上部弁体３４ａを液用ピストン１４の前記弁座部から離間させる。これにより、液用シリンダ１３の内部と下ステム３５の内部とが連通され、液用シリンダ１３内の内容物が、前記弁座部の内側および上部弁体３４ａの外側を通過して下ステム３５内の気液混合室１７に移送される。   At this time, the outside air introduction valve 41a of the valve cylinder portion 41 of the air piston 16 is kept in close contact with the lower surface of the connecting portion 39, and the through hole is closed. Thereby, the air in the lower chamber 40 b is compressed, and this air is transferred to the gas-liquid mixing chamber 17 through the communication gap and the air introduction path 42. At this time, while the lower end opening of the liquid cylinder 13 is closed, the biasing member 33 is compressed and deformed, the liquid piston 14 is moved downward, and the upper valve body 34a of the valve member 34 is moved to the liquid. The piston 14 is separated from the valve seat portion. As a result, the inside of the liquid cylinder 13 and the inside of the lower stem 35 communicate with each other, and the contents in the liquid cylinder 13 pass through the inside of the valve seat part and the outside of the upper valve body 34a to lower the lower stem 35. It is transferred to the gas-liquid mixing chamber 17 inside.

以上のように、押下ヘッド１８を押し下げることにより、気液混合室１７に空気および内容物がそれぞれ移送され、これらは気液混合室１７で合流して混合される。この気液混合体は、発泡部材１９に移送され、下側の発泡エレメント５４のメッシュ体および上側の発泡エレメント５４のメッシュ体を順次通過することで発泡させられて泡体になり、連通路４４を流通してノズル孔４３から吐出される。   As described above, by pushing down the pressing head 18, air and contents are transferred to the gas-liquid mixing chamber 17, and these are merged and mixed in the gas-liquid mixing chamber 17. The gas-liquid mixture is transferred to the foaming member 19 and sequentially passed through the mesh body of the lower foaming element 54 and the mesh body of the upper foaming element 54 to be foamed into a foam, and the communication path 44. And is discharged from the nozzle hole 43.

その後、押下ヘッド１８の押し下げを解除すると、付勢部材３３の弾性復元力により液用ピストン１４が上方に押し上げられる。これにより、液用ピストン１４の前記弁座部が弁部材３４の上部弁体３４ａに当接して閉じられ、気液混合室１７への内容物の移送が停止される。   Thereafter, when the depression of the pressing head 18 is released, the liquid piston 14 is pushed upward by the elastic restoring force of the urging member 33. As a result, the valve seat portion of the liquid piston 14 is brought into contact with the upper valve body 34a of the valve member 34 and closed, and the transfer of the contents to the gas-liquid mixing chamber 17 is stopped.

また、このように上昇する液用ピストン１４とともに、ステム１５および押下ヘッド１８が一体的に上昇し、下ステム３５のフランジ部３５ａが空気用ピストン１６の内筒部３７の下端縁に当接することで、空気導入路４２を通した下室４０ｂと気液混合室１７との連通が遮断され、気液混合室１７への空気の移送が停止される。その後、付勢部材３３の弾性復元力により、空気用ピストン１６が押し上げられることで、前記下室４０ｂ内が負圧状態となり、空気用ピストン１６の弁筒部４１の外気導入弁４１ａが下方に弾性変形させられて、前記貫通孔が開放される。これにより、前記貫通孔および前記上室４０ａを通して下室４０ｂ内に外気が供給される。   In addition to the liquid piston 14 rising in this way, the stem 15 and the pressing head 18 are integrally raised, and the flange portion 35a of the lower stem 35 comes into contact with the lower end edge of the inner cylinder portion 37 of the air piston 16. Thus, the communication between the lower chamber 40b through the air introduction path 42 and the gas-liquid mixing chamber 17 is blocked, and the transfer of air to the gas-liquid mixing chamber 17 is stopped. Thereafter, the air piston 16 is pushed up by the elastic restoring force of the urging member 33, whereby the inside of the lower chamber 40b is in a negative pressure state, and the outside air introduction valve 41a of the valve cylinder portion 41 of the air piston 16 is moved downward. The through hole is opened by being elastically deformed. Thus, outside air is supplied into the lower chamber 40b through the through hole and the upper chamber 40a.

ところで、この吐出容器１は、長期にわたって繰り返し使用する過程で、例えば発泡部材１９上で内容物が固化すること等を起因として、泡体を適正な泡質に発泡し難くなったり、泡体の発泡そのものができなくなったりする可能性がある。この場合、図３に示すように、押下ヘッド１８をステム１５に対して周方向に相対的に回転させ、装着筒部４６のステム１５に対する締め込みを緩めて押下ヘッド１８をステム１５の上端部から離脱させる。その後、押下ヘッド１８から発泡部材１９を下方に向けて引き抜いて離脱させ、発泡部材１９を洗浄する。なおこのとき、発泡部材１９と並行して、押下ヘッド１８の連通路４４およびノズル孔４３を洗浄してもよい。また、押下ヘッド１８から発泡部材１９を離脱させず、発泡部材１９が連通路４４内に配設された状態で、発泡部材１９および連通路４４を一体に洗浄してもよい。   By the way, this discharge container 1 becomes difficult to foam into a suitable foam quality due to solidification of the content on the foaming member 19 in the process of repeated use over a long period of time. Foaming itself may not be possible. In this case, as shown in FIG. 3, the pressing head 18 is rotated in the circumferential direction relative to the stem 15, the tightening of the mounting cylinder portion 46 to the stem 15 is loosened, and the pressing head 18 is moved to the upper end portion of the stem 15. To leave. Thereafter, the foaming member 19 is pulled out downward from the pressing head 18 to be detached, and the foaming member 19 is washed. At this time, the communication path 44 and the nozzle hole 43 of the pressing head 18 may be washed in parallel with the foam member 19. Further, the foaming member 19 and the communication path 44 may be washed together in a state where the foaming member 19 is disposed in the communication path 44 without removing the foaming member 19 from the pressing head 18.

以上説明したように、本実施形態に係るフォーマポンプ１０によれば、押下ヘッド１８が、ステム１５の上端部に着脱自在に配設されているので、押下ヘッド１８をステム１５の上端部から取り外して発泡部材１９を容易に洗浄することができる。これにより、例えば発泡部材１９上で固化した内容物を除去すること等が可能になり、適正な泡質の泡体を長期にわたって吐出することができる。   As described above, according to the former pump 10 according to the present embodiment, since the pressing head 18 is detachably disposed on the upper end portion of the stem 15, the pressing head 18 is detached from the upper end portion of the stem 15. Thus, the foam member 19 can be easily cleaned. Thereby, for example, it is possible to remove the content solidified on the foam member 19, and it is possible to discharge a foam having an appropriate foam quality over a long period of time.

また発泡部材１９が、装着筒部４６の下端部に配設されているので、装着筒部４６をステム１５の上端部から取り外したときに、発泡部材１９を押下ヘッド１８から外部に露出させることが可能になり、発泡部材１９を一層容易に洗浄することができる。
さらに発泡部材１９が、連通路４４内に着脱自在に配設されているので、発泡部材１９を、押下ヘッド１８から離脱させた状態で洗浄することが可能になり、発泡部材１９を確実に洗浄することができる。 Further, since the foaming member 19 is disposed at the lower end portion of the mounting cylinder portion 46, the foaming member 19 is exposed to the outside from the pressing head 18 when the mounting cylinder portion 46 is removed from the upper end portion of the stem 15. Therefore, the foam member 19 can be more easily cleaned.
Further, since the foam member 19 is detachably disposed in the communication path 44, the foam member 19 can be cleaned in a state of being detached from the pressing head 18, and the foam member 19 can be reliably cleaned. can do.
