上記起泡筒80は、上記ステム40の上端部及び連結筒部74に亘って設置されている。起泡筒80の内部には、適数の起泡用メッシュが横設されている。この起泡筒80と液用吐出弁Ｖ２との間のステム部分の内部は、気液混合室とする。 The foaming cylinder 80 is installed across the upper end portion of the stem 40 and the connecting cylinder portion 74. Inside the foaming cylinder 80, an appropriate number of foaming meshes are installed horizontally. Internal stem portion between the foaming cylinder 80 and the liquid ejection valve V 2 is a gas-liquid mixing chamber.
スペーサ82は、押下げヘッド70と内向きフランジ状頂壁部14との間に挿入させている。 The spacer 82 is inserted between the pressing head 70 and the inwardly flanged top wall portion 14.
図１の状態からスペーサ82を外し、押下げヘッド70を押し下げると、ステム40が下降し、これに連動して第２ピストン部材46がステム40より小さく下降する（ステム40に対して相対的に上昇する）ため、空気用吐出弁Ｖ４が開き、下降する第２ピストン部材46により、空気用シリンダ部20ｂ内の空気が加圧される。そしてこの加圧空気が、上記空気用吐出弁Ｖ４から、上記摺動筒部48の内面とステム40の外面との間隙及び上記連結筒部74の内面とステム40の外面との間隙（上述の空気流路Ｐ）を経て、さらにステム40上端面及びステム上端部内面と起泡筒80の対応面との間隙を通って、ステム40内の気液混合室内に入る。他方、第１ピストン部材30が下降してポペット弁体38を液用シリンダ部20ａの弁座面に当接させるまで下降させるとともに、ポペット弁体38がステム40に対して相対的に上昇して逆止弁Ｖ５が開き、液用シリンダ部20ａ内の加圧液体を液用吐出弁Ｖ２を介して気液混合室に導入させる。ここで空気と液体が混合する。そして空気を含んだ液体が起泡筒80内を通ることで発泡し、ノズル76から泡が吐出される。 When the spacer 82 is removed from the state of FIG. 1 and the push-down head 70 is pushed down, the stem 40 descends, and in conjunction with this, the second piston member 46 descends smaller than the stem 40 (relative to the stem 40). rising), the open air discharge valve V 4, the second piston member 46 descends, the air in the air cylinder portion 20b is pressurized. The compressed air is supplied from the air discharge valve V 4 to the gap between the inner surface of the sliding cylinder portion 48 and the outer surface of the stem 40 and the gap between the inner surface of the connecting cylinder portion 74 and the outer surface of the stem 40 (described above). Through the air flow path P), the gas passes through the gap between the upper end surface of the stem 40 and the inner surface of the upper end portion of the stem and the corresponding surface of the foaming cylinder 80, and enters the gas-liquid mixing chamber in the stem 40. On the other hand, the first piston member 30 is lowered and lowered until the poppet valve body 38 is brought into contact with the valve seat surface of the liquid cylinder portion 20a, and the poppet valve body 38 is raised relative to the stem 40. opens the check valve V 5, is introduced into the gas-liquid mixing chamber pressurized liquid in the liquid cylinder portion 20a through the liquid ejection valve V 2. Here, air and liquid are mixed. Then, the liquid containing air is bubbled by passing through the foaming cylinder 80, and the foam is discharged from the nozzle 76.
上記押下げヘッド70の押し下げを解除すると、コイルスプリング36の付勢力により作動部材22が上昇し、その際に第２ピストン部材46がステム40に対して相対的に下降して空気用吐出弁Ｖ４が閉じ、空気用シリンダ部20ｂ内の負圧化によって空気用吸込弁Ｖ３が開いて外気が空気用シリンダ部20ｂ内に導入される。他方、ステム40の上昇によりポペット弁体38は、ステム40との摩擦力で上昇し、液用吸込弁Ｖ１が開いて負圧化した液用シリンダ部20ａ内に容器体２内の液体が導入され、その際に液用吐出弁Ｖ２は閉じる。ポペット弁体38は、第２縦リブＲ２がコイルスプリング36の下面に当接するまでは上昇するが、その後はステム40に対してポペット弁体38の拡開端部がステム嵌合筒部34の上端部に当接するまで下降する。 When the depression of the depression head 70 is released, the actuating member 22 is raised by the urging force of the coil spring 36. At this time, the second piston member 46 is lowered relative to the stem 40, and the air discharge valve V 4 is closed, the negative pressure in the air cylinder portion 20b is air intake valve V 3 outside air is introduced into the air cylinder portion 20b is opened. On the other hand, the poppet valve body 38 by the rise of the stem 40 is elevated by the frictional force of the stem 40, the liquid in the container body 2 inlet valve V 1 is opened for liquid to negative pressure to the liquid cylinder portion 20a is introduced, the liquid ejection valve V 2 in that case closed. Poppet 38 is up to second longitudinal ribs R 2 is brought into contact with the lower surface of the coil spring 36 increases, then the expanded end of the poppet valve body 38 relative to the stem 40 of the stem fitting tubular portion 34 It descends until it comes into contact with the upper end.
本発明においては、図１に示す如く上記外気導入孔58の孔縁から浸水防止用側壁部60を起立している。この浸水防止用側壁部60は、少なくとも外気導入孔58の三方、すなわち、隔壁50の半径方向外方（図２に矢印Ａで示す方向）及びこれと直交する周方向を囲うものとする。これら三方を囲うとする理由は、図４のようにハンディー式泡吐出器を傾けたときに、隔壁50及び内向きフランジ状頂壁部14との間隙中で低くなった部分に集まった水は、まずそれら三方から外気導入孔58に浸入しようとするからである。 In the present invention, as shown in FIG. 1, the infiltration preventing side wall portion 60 is erected from the hole edge of the outside air introduction hole 58. The infiltration prevention side wall 60 surrounds at least three sides of the outside air introduction hole 58, that is, the outer side in the radial direction of the partition wall 50 (the direction indicated by the arrow A in FIG. 2) and the circumferential direction orthogonal thereto. The reason for enclosing these three sides is that when the handy foam dispenser is tilted as shown in FIG. 4, the water collected in the lower portion in the gap between the partition wall 50 and the inwardly flanged top wall portion 14 is This is because, first of all, it tries to enter the outside air introduction hole 58 from these three sides.
図示の浸水防止用側壁部60は、外気導入孔58の孔縁全周から起立する筒状に形成し、隔壁50の半径方向の内方（矢印Ａとは反対の方向）寄りの半筒部分上部に通気口64を有している。図示例では、外気導入孔58の全周を浸水防止用側壁部60で囲んでいるので、浸水を阻む作用を一層確実とすることができる。 The illustrated side wall 60 for preventing flooding is formed in a cylindrical shape standing up from the entire circumference of the outer edge of the outside air introduction hole 58, and is formed on the upper half-cylinder portion of the partition wall 50 in the radial direction (the direction opposite to the arrow A). A vent 64 is provided. In the illustrated example, the entire periphery of the outside air introduction hole 58 is surrounded by the infiltration prevention side wall 60, so that the action of preventing infiltration can be further ensured.
また図示例では、上記浸水防止用側壁部60に浸水防止用頂壁部62を付設している。この浸水防止用頂壁部62は、上記浸水防止用側壁部60を図２で見た断面形状（隔壁の周方向で見た断面形状）において、浸水防止用側壁部60の上端に庇状に連結している。これにより、ハンディー式吐出器を図４よりもさらに大きく傾けたときでも浸水防止用側壁部60の上端側から水が浸入することを阻むことができる。 Further, in the illustrated example, a water-preventing top wall portion 62 is attached to the water-preventing side wall portion 60. The water-inhibiting top wall 62 has a bowl-like shape at the upper end of the water-inhibiting side wall 60 in the cross-sectional shape of the water-inhibiting side wall 60 shown in FIG. It is connected. Thereby, even when the handy-type dispenser is tilted more greatly than in FIG. 4, it is possible to prevent water from entering from the upper end side of the infiltration preventing side wall 60.
図示例と異なり、浸水防止用頂壁部62を省略しても浸水防止用側壁部60の起立長を大きくすることで同様の浸水防止作用を得ることもできる。しかし、それにより第２ピストン部材46の上下巾が大きくなり、これを収納するために大きなスペースが必要となる。浸水防止用頂壁部62を設けることで、そうした不都合を回避できる。 Unlike the example shown in the figure, even if the top wall portion 62 for preventing flooding is omitted, the same flooding preventing effect can be obtained by increasing the standing length of the sidewall portion 60 for preventing flooding. However, the vertical width of the second piston member 46 is thereby increased, and a large space is required to accommodate this. Such inconvenience can be avoided by providing the top wall portion 62 for preventing flooding.
上記通気口64は、上記垂下筒部19の下端よりも上方に位置させている。これにより垂下筒部19の内面に付着した水滴が通気口64内に入ることを防止できる。 The vent 64 is positioned above the lower end of the drooping cylinder part 19. As a result, it is possible to prevent water droplets adhering to the inner surface of the drooping cylinder portion 19 from entering the vent 64.
