Description

本発明はポンプの押下ヘッドに関する。   The present invention relates to a pump pressing head.

容器体に装着してその収容液を液状や霧状、或いは泡状に噴出する如く構成した押下ヘッド式のポンプが種々知られている。これらのポンプでは、噴出用の押下ヘッドを液や泡の流路となるステムの上端に装着した作動部材を上下動可能に設けており、該作動部材を上下動することでポンプを機能させる如く構成している。一例として、装着した容器体内の液と外気とを混合・起泡して泡として噴出するフォーマーポンプが提案されている（例えば，特許文献１参照）。   Various push-down head type pumps are known which are configured to be mounted on a container body and eject the contained liquid in the form of liquid, mist, or foam. In these pumps, an operating member having a pressing head for ejection attached to the upper end of a stem that becomes a flow path of liquid or foam is provided so as to be movable up and down, and the pump can function by moving the operating member up and down. It is composed. As an example, there has been proposed a former pump that mixes and foams the liquid in the attached container and the outside air and ejects it as foam (see, for example, Patent Document 1).

上記特許文献１のフォーマーポンプは、内部を第１ピストンが摺動する液用シリンダと、内部を第２ピストンが摺動する空気用シリンダと、噴出口が設けられるとともに、第１ピストン及び第２ピストンに連係し両ピストンを駆動せしめるポンプヘッドと、液用シリンダから送出された液体と空気用シリンダから送出された空気とが合流する気液混合室と、前記噴出口と気液混合室との間に設置された発泡部材とを備え、ポンプヘッドを押し下げることにより容器体内の液体と外気とを気液混合室で合流せしめ、発泡部材を通して発泡させ、噴出口から泡の状態で噴出する如く構成している。   The former pump of Patent Document 1 is provided with a liquid cylinder in which a first piston slides, an air cylinder in which a second piston slides, a jet port, and a first piston and a first piston. A pump head linked to two pistons for driving both pistons, a gas-liquid mixing chamber in which the liquid sent out from the liquid cylinder and the air sent out from the air cylinder merge, the jet port and the gas-liquid mixing chamber; And a foaming member installed between the two, the pump head is pushed down so that the liquid in the container and the outside air are merged in the gas-liquid mixing chamber, foamed through the foaming member, and ejected in the form of bubbles from the ejection port. It is composed.

また、これらのフォーマーポンプでは、泡噴出が終わるとノズル管内の残泡を自動的に内部に逆流させてノズル管の目詰まりを防止する機構を備えたものも提案されている。（例えば特許文献２参照）   In addition, these former pumps have also been proposed which have a mechanism for preventing clogging of the nozzle tube by automatically flowing back the remaining bubbles in the nozzle tube to the inside when the bubble ejection ends. (For example, see Patent Document 2)

上記特許文献２のフォーマーポンプは、液体シリンダー底部開口に設けられる吸込み弁にこのシリンダー軸芯部を立ち上がり先端が排液管（ステム）内下部に摺接して入り込む棒体を設け、排液管（ステム）が泡噴出時に押し下げられたときに棒体の挿入量を増大して内容積が減縮し、上昇する復帰時に棒体の挿入量が低減して内容積が増大して負圧化し、この負圧化でノズル管内の残泡を内部に吸引させている。
特開平０９−１１８３５１号公報 特開平０９−１９３９５３号公報 The former pump of the above-mentioned patent document 2 is provided with a rod body in which a suction shaft provided at the bottom opening of the liquid cylinder is provided with a cylinder shaft core portion that rises up and slides into a drain pipe (stem). When the (stem) is pushed down when the foam is ejected, the insertion amount of the rod body is increased and the internal volume is reduced, and when returning to the rising position, the insertion amount of the rod body is reduced and the internal volume is increased and negative pressure is obtained. Residual bubbles in the nozzle tube are sucked into the inside by this negative pressure.

本発明はこの様なポンプ、特にフォーマーポンプへの採用に好適な押下ヘッドを提案するものであり、ノズル先端部の残液，残泡を上流側へ吸引してノズル先端からの液垂れ等を防止できる押下ヘッドを提案する。特に噴出対象が泡の場合には吸引された泡が時間の経過とともに液状化する傾向があり、それらがポンプ容器の取り扱い状態で再びノズル先端に逆流するのを防止できる押下ヘッドを提案する。   The present invention proposes a pressing head suitable for use in such a pump, particularly a former pump. The residual liquid at the nozzle tip, the residual bubbles are sucked upstream, and dripping from the nozzle tip, etc. We propose a pressing head that can prevent this. In particular, when the target to be ejected is a foam, there is a tendency that the sucked foam tends to be liquefied as time passes, and a pressing head is proposed that can prevent them from flowing back to the nozzle tip again in the handling state of the pump container.

第１の手段として、以下の通り構成した。即ち、上方付勢状態で上下動可能に突出したステムD2の上端に押下ヘッドD4を備え、押下ヘッドD4を上下動させることで、装着した容器体内収納液を押下ヘッドD4の噴出口75より噴出する如く構成したポンプの押下ヘッドD4であって、ステムD2の外周上端部に液密摺動可能に嵌合させた摺動筒60を頂板61より垂設したヘッド本体D4a と、頂板61上に起伏可能に設けるとともに、伏臥状態でステムD2内と連通し且つ起立状態で非連通のノズルD4b とを備え、ステムD2に対して上方付勢状態で所定幅の押込みが可能に構成し、ステムD2に対するヘッド本体D4a の押下抗力がステム自体の押下抗力よりも小であることを特徴とする。 The first means is configured as follows. That is, the pressing head D 4 is provided at the upper end of the stem D 2 that protrudes up and down in the upward biased state, and the pressing head D 4 is moved up and down, so that the liquid stored in the container is ejected from the pressing head D 4 . a pressing head D 4 of pumps as configured for ejecting from the outlet 75, the head body D to the sliding tube 60 which has fluid-tight slidably fitted on the outer peripheral upper end portion of the stem D 2 and vertically from top plate 61 4a and a nozzle D 4b that is provided on the top plate 61 so as to be able to rise and fall, communicates with the inside of the stem D 2 in the prone state, and communicates with the stem D 2 in a standing state, and has a predetermined width in an upward biased state with respect to the stem D 2 It is characterized in that the pressing force of the head body D 4a against the stem D 2 is smaller than the pressing force of the stem itself.

第２の手段として、以下の通り構成した。即ち、第１の手段に於いて、ヘッド本体D4a 上への起立状態から先端をヘッド本体D4a より突設した伏臥状態へのノズルD4b の起伏が可能に構成し、ノズルD4b の起立状態でのみ嵌合が可能なカバーキャップＦを着脱可能に嵌合させた。 The second means is configured as follows. That, in the first means, and undulations can configure the nozzle D 4b from the upright state onto the head body D 4a to the prone state projecting from the front end from the head body D 4a, standing nozzle D 4b The cover cap F, which can be fitted only in the state, was detachably fitted.

第３の手段として、以下の通り構成した。即ち、第１の手段又は第２の手段のいずれかの手段に於いて、上記ポンプが、押下ヘッドD4を上下動させることで、液と空気を混合・起泡して押下ヘッドD4の噴出口75より泡として噴出する如く構成したフォーマーポンプである。 The third means was configured as follows. That is, in either of the first means and the second means, the pump moves the pressing head D 4 up and down to mix and foam the liquid and air, so that the pressing head D 4 This is a former pump configured to be ejected as bubbles from the ejection port 75.

第４の手段として、以下の通り構成した。即ち、第１の手段乃至第３の手段のいずれかの手段に於いて、ステムD2外周所定位置に、押下ヘッドD4の下端部が係止されるフランジ状部43を突設した。 The fourth means is configured as follows. That is, at any of the means of the first means or third means, the stem D 2 the outer peripheral position, projecting from the flange portion 43 of the lower end of the pressing head D 4 is locked.

本発明の押下ヘッドD4は、ポンプ内容物の噴出後にノズルD4b 内の残液或いは残泡を内部に吸引でき、ノズルD4b からの液垂れ等を防止できるとともに、ノズルD4b 内に於ける液、泡等が固化して噴出路74を狭くする等の不都合を防止できる。しかも、使用後はノズルD4b を起立して噴出路74を閉塞することができるため、液垂れ等をより確実に防止できる。 Pressing head D 4 of the present invention, residual liquid or Zan'awa in the nozzle D 4b after ejection of the pump contents can sucked into the, it is possible to prevent dripping and the like from the nozzle D 4b, at the nozzle D 4b It is possible to prevent inconveniences such as the liquid, bubbles and the like solidifying and narrowing the ejection path 74. Moreover, after use, the nozzle D 4b can be erected to close the ejection path 74, so that dripping or the like can be prevented more reliably.

ヘッド本体D4a 上への起立状態から先端をヘッド本体D4a より突設した伏臥状態へのノズルD4b の起伏が可能に構成し、ノズルD4b の起立状態でのみ嵌合が可能なカバーキャップＦを着脱可能に嵌合させた場合には、ノズルD4b を起立させて噴出路74を閉塞しなければカバーキャップＦが装着できないため、無意識に噴出路74の閉塞ができる等の利点がある。 Relief nozzle D 4b from the upright state onto the head body D 4a to the prone state projecting from the front end from the head body D 4a can be configured, fitting can cover cap only in an upright state of the nozzle D 4b When F is detachably fitted, the cover cap F cannot be attached unless the nozzle D 4b is erected to close the ejection path 74, so that there is an advantage that the ejection path 74 can be closed unconsciously. .

上記ポンプが、押下ヘッドD4を上下動させることで、液と空気を混合・起泡して押下ヘッドD4の噴出口75より泡として噴出する如く構成したフォーマーポンプである場合には、泡は特に吸引し易いため、十分な吸引力を得られることにより泡をステムD2内上部に吸引することができる。また、ノズルD4b を起立させれば外部と非連通なステム内上端部に泡が収納されるため、ポンプを装着した容器を寝かす等しても漏出を防止でき、特に、時間の経過とともに液状化した泡であっても確実に漏出を防止できる。 When the pump is a former pump configured to move the press head D 4 up and down to mix and foam liquid and air and eject the foam as a bubble from the jet head 75 of the press head D 4 . foam particularly liable to suction, it is possible to suck the bubbles in the upper inner stem D 2 by obtain a sufficient attraction force. Also, if the nozzle D 4b is erected, the foam is stored in the upper end of the stem that is not in communication with the outside. Therefore, leakage can be prevented even when the container equipped with the pump is laid down. Leakage can be reliably prevented even if the foamed foam.

ステムD2外周所定位置に、押下ヘッドD4の下端部が係止されるフランジ状部43を突設した場合には、押下ヘッドD4のステムD2に対する押し下げ幅を特定でき、その結果、ステムD2外周の摺動部44の摺動幅を特定できるため、常時所定量の吸引を行える利点がある。また、摺動部44がヘッド本体頂板61に衝突して変形する等の不都合を防止できる。 The stem D 2 the outer peripheral position, if the lower end of the pressing head D 4 has projecting flange-like portion 43 to be engaged can identify the width depressed relative to the stem D 2 of the pressing head D 4, as a result, because it can identify the slide width of the stem D 2 the outer periphery of the sliding portion 44, there is an advantage that allows the aspiration of all times a predetermined amount. Further, it is possible to prevent inconveniences such as the sliding portion 44 colliding with the head main body top plate 61 and being deformed.

The passage and the internal passage of the cylindrical portion 71 constitute an ejection path 74, and the tip of the ejection path 74 is opened as an ejection port 75.

また、押下ヘッドD4は、ステムD2に対するヘッド本体D4a の押下抗力がステム自体の押下抗力より小になる様に構成している。この様に構成するためには、基本的にはステムD2を上方付勢させるためのコイルスプリングs1よりも、押下ヘッドD4を上方付勢させるためのコイルスプリングs2の弾発力を小さく選択すれば良く、その他に摺動部44摩擦力や液用ピストン摺動部31或いは空気用費摺動部52の摩擦力等を考慮してこれらを選択すれば良い。 Also, pressing the head D 4 is pressed drag head body D 4a is configured so as to be a smaller than pressing force of the stem itself relative to the stem D 2. In order to configure in this way, basically, the spring force of the coil spring s 2 for urging the pressing head D 4 upward is more than the coil spring s 1 for urging the stem D 2 upward. It is only necessary to select a small value, and in addition, the frictional force of the sliding portion 44 friction force, the liquid piston sliding portion 31 or the air cost sliding portion 52 may be selected.

ポペット弁体Ｅは、下端部外面に、それぞれ液用シリンダ21の係止リブ33間に位置させる、周方向複数の係止突部80を突設しており、液用シリンダ21内からステムD2内下部に至る長さを有している。下面周縁部はテーパ状に形成して液用シリンダ21底壁部上面の吸込み弁用の弁座とで吸込み弁81を形成しており、吸込み弁用の弁座と下面が当接する位置から、各係止突部80がコイルスプリングs1下面に当接する位置までの上下動が可能に装着している。上端にはテーパ筒状に拡開する逆止弁体を形成し、この逆止弁体と逆止弁用の弁座とで上記逆止弁32を形成している。 The poppet valve body E is provided with a plurality of circumferentially extending locking projections 80 positioned on the outer surface of the lower end portion between the locking ribs 33 of the liquid cylinder 21, and the stem D from within the liquid cylinder 21. 2 It has a length that reaches the lower part. The lower peripheral edge portion is formed in a taper shape, and the suction valve 81 is formed with the suction valve valve seat on the upper surface of the bottom wall of the liquid cylinder 21, from the position where the suction valve valve seat and the lower surface abut, each locking projection 80 is mounted can be vertically moved to the position abutting the coil spring s 1 lower surface. A check valve body that expands in a tapered cylindrical shape is formed at the upper end, and the check valve 32 is formed by the check valve body and the valve seat for the check valve.

カバーキャップＦは、装着キャップＡの外周上部から頂部にわたり嵌合する袴部分90を備え、袴部分90の内周縁からヘッド本体D4a 外周に位置する周壁91を延設し、周壁91上端縁より頂壁92を延設して構成しており、着脱自在に装着キャップＡに嵌合させている。このカバーキャップＦは、図２に示すノズルD4b の伏臥状態では装着が不可能で、図１に示す如きノズルD4b の起立状態でのみ嵌合が可能に構成している。 The cover cap F includes a flange portion 90 that fits from the upper outer periphery to the top of the mounting cap A, and a peripheral wall 91 located on the outer periphery of the head body D 4a extends from the inner peripheral edge of the flange portion 90. The top wall 92 is extended and is detachably fitted to the mounting cap A. The cover cap F cannot be mounted when the nozzle D 4b shown in FIG. 2 is in the prone state, and can be fitted only when the nozzle D 4b is raised as shown in FIG.

上記フォーマーポンプ１は、図１の状態からカバーキャップＦを外して図２の状態にノズルD4b を回動伏臥させ、その状態から押下ヘッドD4を押し下げると、ステムD2自体の押下抗力の方が押下ヘッドD4のステムD2に対する押下抗力より大きい為、最初ステムD2は下がらず、ステムD2に対してヘッド本体D4a が下降し、ヘッド本体D4a の周壁部62の下端がフランジ状部43上面に当接するまで下降する。次いでステムD2が下降し、その際空気用ピストンがステムD2に対して相対的に上昇して空気吐出弁53が開き、下降する空気用ピストンD3により空気用シリンダ20内の空気が加圧されて空気通路41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Ｅ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、ポペット弁体ＥがステムD2に対して相対的に上昇して逆止弁32が開き、液用シリンダ21内の加圧液を空気吐出弁53を介して気液混合室に導入させ、ここで、気液を混合する。この際ポペット弁体Ｅはその逆止弁体がステムD2内周の各縦突条内面に摺動してステムD2に対して相対的に上昇する。気液混合室で混合された気液は、起泡部材42を通過して発泡し、噴出口75より泡として噴出される。 When the former pump 1 removes the cover cap F from the state shown in FIG. 1 and turns the nozzle D 4b into the state shown in FIG. 2, and presses down the pressing head D 4 from this state, the pressing force of the stem D 2 itself is pressed. because who is greater than the pressing force against the stem D 2 of the pressing head D 4, the lower end of the first stem D 2 is not reduced, the head body D 4a descends relative to the stem D 2, the peripheral wall 62 of the head body D 4a Is lowered until it comes into contact with the upper surface of the flange-like portion 43. Then the stem D 2 is lowered, whereby the air piston is relatively increased to relative to the stem D 2 opens the air discharge valve 53, air in the air cylinder 20 is pressurized by an air piston D 3 which descends Compressed and introduced into the gas-liquid mixing chamber R through the air passage 41. On the other hand, the lowering until brought into contact with the valve seat for the suction valve poppet E lowered the liquid cylinder 21, a relatively elevated check valve poppet E is relative to the stem D 2 32 opens, and the pressurized liquid in the liquid cylinder 21 is introduced into the gas-liquid mixing chamber through the air discharge valve 53, where the gas-liquid is mixed. At this time the poppet valve body E is relatively raised with respect to the stem D 2 slides in the vertical projection the inner surface of the inner periphery of the stem D 2 is the check valve body. The gas-liquid mixed in the gas-liquid mixing chamber passes through the foaming member 42 and foams and is ejected as bubbles from the ejection port 75.

押下ヘッドD4の押圧を解除すると、コイルスプリングs1の付勢力により作動部材Ｄが上昇し、ステムD2の上方付勢力により押下ヘッドD4も同様に上昇するが、この際、例えば押下ヘッドD4上面を押圧した手が離れないうちにステムD2の上昇が行われる。その際空気用ピストンD3がステムD2に対して相対的に下降して空気吐出弁53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54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D2の上昇によりポペット弁体Ｅは、逆止弁体とステム内周の各縦突条との摩擦力で上昇し、吸込み弁81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、その際空気吐出弁53は閉じる。ポペット弁体Ｅはその係止突部80がコイルスプリングs1の下面に当接するまで上昇するが、その後はステムD2に対して、逆止弁体が逆止弁用の弁座に当接するまで相対的に下降する。 When releasing the pressing of the pressing head D 4, actuating member D by the urging force of the coil spring s 1 is increased, similarly rises pressing head D 4 by the upper biasing force of the stem D 2, but this time, for example, pressing the head increase of the stem D 2 is carried out in less away hand presses the D 4 top. At that time, the air piston D 3 descends relative to the stem D 2 to close the air discharge valve 53, and the outside air introduction valve 54 is opened by the negative pressure in the air cylinder 20, so that the outside air flows into the air cylinder 20. Introduced in. On the other hand, the poppet valve element E rises due to the frictional force between the check valve element and each vertical protrusion on the inner periphery of the stem due to the rise of the stem D 2 , and the suction valve 81 is opened to create a negative pressure in the liquid cylinder 21. Then, the liquid in the container body 100 is introduced, and the air discharge valve 53 is closed at that time. The poppet valve body E rises until its locking projection 80 abuts against the lower surface of the coil spring s 1 , and then the check valve body abuts against the valve seat for the check valve against the stem D 2 . Relatively descends.

次いで押下ヘッドD4がコイルスプリングs2の上方付勢力によりステムD2に対して相対的に上昇し、噴出路74内に残留する泡をステムD2内上端部に引き込む。次にノズルD4b を回動起立させて噴出路74と連通孔64との連通を遮断した後、カバーキャップＦを装着する。 Then pressing head D 4 is relatively raised with respect to the stem D 2 by the upper biasing force of the coil spring s 2, draw bubbles remaining in the ejection path 74 in the upper portion in the stem D 2. Next, the nozzle D 4b is turned upright to block the communication between the ejection path 74 and the communication hole 64, and then the cover cap F is attached.
