In this example, as described above, an example in which the outer peripheral surface of the container body 10 and the outer peripheral surfaces of the mounting cylinder 20 and the peripheral wall portion 22a are formed to have substantially the same diameter is shown. The present invention is not limited to the case where the same diameter is formed.
上記フォーマーポンプＢは、図１の状態からオーバーキャップＤを外して吐出ヘッド３３を押し下げると、空気用ピストン３２がステム３１に対して相対的に上昇し、空気吐出弁４０が開き、また下降する空気用ピストン３２により空気用シリンダ２１内の空気が加圧され、空気通路４１を介して吐出弁３４下流位置のステム３１内の気液混合室Ｒ内に導入される。一方、液用ピストン３０が下降してポペット弁体２４を吸込み弁用の弁座に当接させるまで下降させるとともに、逆止弁３６が開き、液用シリンダ２２内の加圧液を吐出弁３４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。気液混合室Ｒで混合された気液は起泡層を通過して発泡し、吐出ヘッド３３のノズル４７先端の吐出口４８より泡として吐出される。 In the former pump B, when the overcap D is removed from the state of FIG. 1 and the discharge head 33 is pushed down, the air piston 32 rises relative to the stem 31 and the air discharge valve 40 opens and descends. The air piston 21 pressurizes the air in the air cylinder 21 and is introduced into the gas-liquid mixing chamber R in the stem 31 downstream of the discharge valve 34 via the air passage 41. On the other hand, the liquid piston 30 is lowered and lowered until the poppet valve body 24 is brought into contact with the valve seat for the suction valve, and the check valve 36 is opened to discharge the pressurized liquid in the liquid cylinder 22 to the discharge valve 34. Is introduced into the gas-liquid mixing chamber R through which the gas-liquid is mixed. The gas-liquid mixed in the gas-liquid mixing chamber R passes through the foaming layer and foams and is discharged as bubbles from the discharge port 48 at the tip of the nozzle 47 of the discharge head 33.
吐出ヘッド３３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Ｂ２が上昇し、その際空気用ピストン３２がステム３１に対して相対的に下降して空気吐出弁４０が閉じ、空気用シリンダ２１内の負圧化によって外気導入弁４２が開いて外気が空気用シリンダ２１内に導入される。一方、ステム３１の上昇によりポペット弁体２４は上昇し、吸込み弁２５が開いて負圧化した液用シリンダ２２内に容器体Ａ内の液が導入され、その際吐出弁３４及び逆止弁３６は閉じる。また、容器体Ａ内の液の減少に伴って容器体Ａ内が負圧化し、負圧解除弁５０が開いて外気が容器体Ａ内へ導入される。 When the pressing of the discharge head 33 is released, the actuating member B2 is lifted by the biasing force of the coil spring s. At that time, the air piston 32 is lowered relative to the stem 31 and the air discharge valve 40 is closed, and the air cylinder is closed. Due to the negative pressure in the air 21, the outside air introduction valve 42 opens and the outside air is introduced into the air cylinder 21. On the other hand, the poppet valve body 24 ascends as the stem 31 rises, and the liquid in the container body A is introduced into the liquid cylinder 22 that is opened and the suction valve 25 is opened to a negative pressure. At that time, the discharge valve 34 and the check valve 36 closes. Further, as the liquid in the container body A decreases, the inside of the container body A becomes negative pressure, the negative pressure release valve 50 is opened, and the outside air is introduced into the container body A.
容器体Ａ内の液が無くなった場合には、フォーマーポンプＢより容器体Ａを外して液の詰め替えを行うことができ、或いは、液の充填されている詰め替え用の容器体Ａを装着することで再使用が可能となる。 When the liquid in the container body A runs out, the container body A can be removed from the former pump B and the liquid can be refilled, or the refillable container body A filled with the liquid can be mounted. Can be reused.
