泡吐出器として、大径の空気用シリンダと小径の液用シリンダを上下に同心円状に連設したシリンダ部材と、液用シリンダ内を摺動する液用ピストンをステム外周下部より突設するとともに、空気用シリンダ内を摺動する空気用ピストンをステム外周上部に連繋させ、ステム上端に吐出ヘッドを嵌着して上方付勢状態で上下動可能に装着した作動部材とを備え、作動部材の上下動により液用シリンダ内の液と空気用シリンダ内の空気を合流させて起泡部材を介して起泡させ、吐出ヘッドの吐出口より吐出する如く構成したものが知られている。（例えば、特許文献１参照） As a foam discharger, a cylinder member in which a large-diameter air cylinder and a small-diameter liquid cylinder are connected concentrically up and down, and a liquid piston sliding inside the liquid cylinder project from the lower part of the outer periphery of the stem. A pneumatic piston that slides in the pneumatic cylinder is connected to the upper portion of the outer periphery of the stem, and an operating member that is fitted to the upper end of the stem so as to be movable up and down in an upward biased state. A configuration is known in which the liquid in the liquid cylinder and the air in the air cylinder are merged by vertical movement to be bubbled through a foaming member and discharged from the discharge port of the discharge head. (For example, see Patent Document 1)

Further, the shapes of the upward concavo-convex surface f1 and the downward concavo-convex surface f2 are not limited to the above-described triangular shape, and the downward concavo-convex surface f2 is formed on the upward concavo-convex surface f1 by rotating the upper member C4b with respect to the lower member C4a. Various shapes can be adopted as long as the shape can slide up and raise the upper member C4b relative to the lower member C4a. For example, the shapes of the corrugated upwardly uneven surface f1 and the downwardly uneven surface f2 may be used. .
カバーキャップＥは、装着キャップＡの外周上部に周壁下端部を着脱可能に嵌合させ、吐出ヘッドＣ４を被覆して着脱可能に装着させている。 The cover cap E is detachably fitted to the upper periphery of the mounting cap A so that the lower end of the peripheral wall is detachable and covers the ejection head C4.
上記泡吐出器１は、図１の状態からカバーキャップＥを外して吐出ヘッドＣ４を押し下げると、空気用ピストンＣ３がステムＣ２に対して相対的に上昇して空気吐出弁４９が開き、下降する空気用ピストンＣ３により空気用シリンダ２０内の空気が加圧されて空気供給路ｐを介して気液混合室Ｒ内に導入される。一方、液用シリンダ２１が下降してポペット弁体Ｄを吸込み弁用の弁座２２に当接させるまで下降させるとともに、ポペット弁体ＤがステムＣ２に対して相対的に上昇して逆止弁８２が開き、液用シリンダ２１内の加圧液を吐出弁３７を介して気液混合室Ｒに導入させ、ここで気液を混合する。この際ポペット弁体ＤはステムＣ２に対して相対的に上昇する。気液混合室Ｒで混合された気液はメッシュ７６ａを通過して発泡し、吐出ヘッドＣ４のノズル７４から外部へ吐出される。 When the foam discharger 1 removes the cover cap E from the state of FIG. 1 and pushes down the discharge head C4, the air piston C3 rises relative to the stem C2 and the air discharge valve 49 opens and descends. Air in the air cylinder 20 is pressurized by the air piston C3 and is introduced into the gas-liquid mixing chamber R through the air supply path p. On the other hand, the liquid cylinder 21 is lowered and lowered until the poppet valve body D is brought into contact with the valve seat 22 for the suction valve, and the poppet valve body D is relatively lifted with respect to the stem C2 to check valve. 82 opens, the pressurized liquid in the liquid cylinder 21 is introduced into the gas-liquid mixing chamber R through the discharge valve 37, and the gas-liquid is mixed here. At this time, the poppet valve body D rises relative to the stem C2. The gas-liquid mixed in the gas-liquid mixing chamber R passes through the mesh 76a, foams, and is discharged to the outside from the nozzle 74 of the discharge head C4.
吐出ヘッドＣ４の押圧を解除すると、コイルスプリングｓの付勢力により作動部材Ｃが上昇し、その際空気用ピストンＣ３がステムＣ２に対して相対的に下降して空気吐出弁４９が閉じ、空気用シリンダ２０内の負圧化によって外気導入弁４８が開いて外気が空気用シリンダ２０内に導入される。一方、ステムＣ２の上昇によりポペット弁体Ｄは、逆止弁８２と各縦突条３８の摩擦力で上昇し、吸込み弁８３が開いて負圧化した液用シリンダ２１内に容器体１００内の液が導入され、その際吐出弁３７は閉じる。ポペット弁体Ｄはその係止突部８０がコイルスプリングｓの下面に当接するまで上昇するが、その後はステムＣ２に対して、逆止弁体８１が逆止弁用の弁座３２に当接するまで相対的に下降する。 When the pressure of the discharge head C4 is released, the actuating member C is lifted by the biasing force of the coil spring s. At this time, the air piston C3 is lowered relative to the stem C2, and the air discharge valve 49 is closed. Due to the negative pressure in the cylinder 20, the outside air introduction valve 48 is opened and outside air is introduced into the air cylinder 20. On the other hand, the poppet valve body D is lifted by the frictional force of the check valve 82 and each of the vertical protrusions 38 due to the rise of the stem C2, and the suction valve 83 is opened to bring the negative pressure into the liquid cylinder 21. In this case, the discharge valve 37 is closed. The poppet valve body D rises until its locking projection 80 comes into contact with the lower surface of the coil spring s. Thereafter, the check valve body 81 comes into contact with the valve seat 32 for the check valve with respect to the stem C2. Relatively descends.
