Description

本発明は、加圧媒体を利用したエアゾール容器あるいはプライミングを伴うポンプ付き容器等のステム等に装着してその押圧操作により容器内の内容物を適量排出するのに好適な噴出ヘッドに関するものである。   The present invention relates to an ejection head that is suitable for discharging an appropriate amount of contents in a container by attaching to a stem or the like such as an aerosol container using a pressurized medium or a container with a pump with priming. .

乳液等の化粧料を入れる容器やシャンプー、リンスあるいは整髪料等を入れる容器においては、容器内の内容物を押圧操作により適量排出することを可能とした噴出ヘッドが装着されている。   In a container for storing cosmetics such as a milky lotion or a container for storing shampoo, rinse, hairdressing or the like, an ejection head that can discharge an appropriate amount of the contents in the container by a pressing operation is mounted.

ところで、この種の噴出ヘッドは、使いやすさ、使い勝手の改善を図る観点から噴出口を斜め下向きに指向させるべくノズルに傾斜角度を付したものがあるけれども、この種の噴出ヘッドはノズルの噴出口は常に開放された状態にあるのが普通であり、内容物の排出を停止した後においても通路内に残存する内容物が噴出口から垂れ落ちる、いわゆる液垂れが避けられず、また、内容物の通路内での固化によりその排出が困難となる不具合があった。   By the way, this type of ejection head has a nozzle with an inclined angle so that the ejection port is directed obliquely downward from the viewpoint of improving usability and usability. Normally, the outlet is always open. Even after the discharge of the contents is stopped, the contents remaining in the passage hang down from the spout, so-called liquid dripping cannot be avoided. There was a problem that it became difficult to discharge due to solidification of the material in the passage.

上述のような従来の問題の解決を図るものとしてはノズルの先端にスリット付きの弾性閉塞板を設けた液体注出ポンプが提案されている（例えば特許文献1参照）が、かかる注出ポンプにおいては外界とノズル内がスリットを隔て隔絶されているのみなのでノズル内の圧力が抜けきらない状態にあってはスリットを通して液体が垂れ落ちるのが避けられず未だ改善の余地が残されていた。   As a solution to the above-described conventional problems, a liquid dispensing pump in which an elastic blocking plate with a slit is provided at the tip of a nozzle has been proposed (see, for example, Patent Document 1). In the state where the outside and the inside of the nozzle are only separated from each other by the slit, it is inevitable that the liquid drips through the slit in a state where the pressure in the nozzle cannot be released, and there is still room for improvement.

この点に関して近年では、噴出ヘッドのヘッド本体内にノズルの噴出口に適合する先端部を備えたノズルピンを組み込み、噴出ノズルの押圧操作にのみノズルピンをスライドさせてノズルの噴出口を開放するようにした構造の噴出ヘッド（例えば、特許文献1参照）を適用する試みもなされているところ、かかる噴出ヘッドは、ノズルピン（摺動杵）の後端部に係合板を連係させてスライドさせる構造であり、ノズルの噴出口を斜め下向きに指向させるのが難しい状況にあった。
特開平9-40000号公報 特許第3814753号明細書 In recent years, a nozzle pin having a tip adapted to the nozzle outlet is incorporated in the head body of the jet head, and the nozzle pin is slid only in the pressing operation of the jet nozzle to open the nozzle jet. Attempts have also been made to apply an ejection head having a structure as described above (see, for example, Patent Document 1), and this ejection head has a structure in which an engagement plate is linked to the rear end of a nozzle pin (sliding rod) and slid. It was difficult to orient the nozzle outlet at an angle downward.
Japanese Patent Laid-Open No. 9-40000 Patent No. 3814753

本発明の課題は、上記のような従来の問題を回避し得る新規な噴出ヘッドを提案するところにある。   An object of the present invention is to propose a novel ejection head capable of avoiding the conventional problems as described above.

本発明は、ポンプのステムに嵌合する筒体を有し、該ステムに帯同して移動可能なベースと、このベースにスライド可能に被さりその内側に内容物の貯留空間を区画形成するヘッドと、このヘッドの貯留空間につながる通路を有し、貯留空間内の内容物を外界へ向けて噴出させるノズルと、このノズルの通路内にスライド可能に弾性支持されヘッドの押し込みに従う後方へのスライドにてノズルの噴出口を開放するシャットオフピンを備えた噴出ヘッドであって、
前記ベースに、筒体の先端部分に一体的につながり、内容物の流入経路を残して貯留空間内にて起立する傾斜壁部を設け、
前記シャットオフピンに、その後端部においてつながり前記通路を通して貯留空間に伸延する連結部材を配設してなり、
該連結部材は、ヘッドの押し込みに伴う該傾斜壁部に沿う摺動にて該シャットオフピンを後方へスライドさせる開口部を有することを特徴とする噴出ヘッドである。 The present invention has a cylindrical body that fits into a stem of a pump, a base that can move along with the stem, a head that slidably covers the base, and that forms a storage space for contents inside the base. The nozzle has a passage connected to the storage space of the head, and ejects the contents in the storage space toward the outside. The nozzle is elastically supported so as to be slidable in the passage of the nozzle and slides backward according to the pushing of the head. A jet head having a shut-off pin that opens a nozzle jet port,
The base is provided with an inclined wall portion that is integrally connected to the distal end portion of the cylindrical body and stands up in the storage space leaving an inflow path for the contents,
A connection member connected to the shut-off pin at the rear end thereof and extending to the storage space through the passage is provided.
The connecting member is an ejection head characterized by having an opening that slides the shut-off pin rearward by sliding along the inclined wall as the head is pushed.

上記の構成になる噴出ヘッドにおいて、前記ノズルは、噴出口を斜め下向きに指向させる傾斜角度を設けるのが好ましく、連結部材については、ノズルの傾斜角度と同等の傾斜角度を付する湾曲部を設けるのが望ましい。   In the ejection head configured as described above, it is preferable that the nozzle is provided with an inclination angle that directs the ejection port obliquely downward, and the connecting member is provided with a curved portion having an inclination angle equivalent to the inclination angle of the nozzle. Is desirable.

シャットオフピンをノズルの噴出口に近い先端部で弾性支持し、該シャットオフピンの後端に、内容物の貯留空間に向けて伸延する連結部材を設けて、この連結部材を用いてシャットオフピンをスライドさせるようにしたため、ノズルの向きを比較的自由に変更することが可能となる。   The shut-off pin is elastically supported at the tip near the nozzle outlet, and a connecting member is provided at the rear end of the shut-off pin to extend toward the content storage space. Since the pins are slid, the direction of the nozzle can be changed relatively freely.

また、シャットオフピンによってノズルの噴出口を確実に閉塞することができるので、内容物の排出後において液垂れが生じたり、内容物の固化、固着を引き起こすことがない。   In addition, since the nozzle outlet can be reliably closed by the shut-off pin, no dripping occurs after the contents are discharged, and the contents are not solidified or fixed.

以下、図面を参照して本発明をより具体的に説明する。
図1は本発明にしたがう噴出ヘッドの実施の形態を模式的に示した図である。図における符号1は容器の口部にねじ止め（アンダーカットによる係合であってもよい）されるキャップ、2はキャップ1に組み込まれたポンプである。このポンプ2はヘッドの押し込みによりステム2aを介してピストン2bをシリンダー2c内で往復移動させることによりパイプPを通して内容物を吸引するとともに、加圧、圧送してノズルの噴出口より外界へ向けて排出させる。 Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a diagram schematically showing an embodiment of an ejection head according to the present invention. Reference numeral 1 in the figure denotes a cap screwed to the mouth of the container (may be engaged by undercut), and 2 is a pump incorporated in the cap 1. This pump 2 sucks the contents through the pipe P by reciprocating the piston 2b in the cylinder 2c through the stem 2a by pushing the head, and pressurizing and pumping the contents toward the outside from the nozzle outlet Let it drain.

また、3はベースである。ベース3はポンプ2のステム2aに嵌合する筒体3aと、この筒体3aの外周壁に一体的に設けられたフランジ3bと、このフランジ3bの上面にて起立する内側環状壁（シール部材として機能する）3cと、同じくフランジ3bの上面にて起立し、該内側環状壁3cを間隔を隔てて取り囲む外側環状壁3dからなる。外側環状壁3dの外観を一部断面にして図2に示すように、その外周面にはヘッドの外壁の内面に設けられた縦リブに適合する縦溝3d１と、ノズルの通路につながる切欠部hが形成されていて、該縦溝3d１によりヘッドの傾きを防止するともにその位置合わせができるようになっている。また、外側環状壁3dの外面下側よりには爪部3d２が設けられている。 3 is a base. The base 3 has a cylindrical body 3a fitted to the stem 2a of the pump 2, a flange 3b integrally provided on the outer peripheral wall of the cylindrical body 3a, and an inner annular wall (seal member) standing on the upper surface of the flange 3b. 3c) and an outer annular wall 3d that stands on the upper surface of the flange 3b and surrounds the inner annular wall 3c with a space therebetween. As shown in FIG. 2 with a partial cross-sectional view of the outer annular wall 3d, the outer circumferential surface thereof has a longitudinal groove 3d 1 adapted to a longitudinal rib provided on the inner surface of the outer wall of the head, and a notch connected to the nozzle passage. Part h is being formed, it is both to allow its positioning to prevent inclination of the head by which grooves 3d 1. Further, the claw portion 3d 2 is provided on the outer surface lower side of the outer annular wall 3d.

4はベース3の上部でスライド可能に被さりその内側に内容物の貯留空間（内容物を吸引、加圧、圧送するための空間）Mを区画形成するヘッドである。このヘッド4は下向きに開放された環状の内壁4aと、この内壁4aを取り囲みヘッド4をベース3において抜け止め保持する外壁4bと、内壁4a及び外壁4bの上端に一体連結する天面壁4cからなる。外壁4bの内面にはベース3の縦溝3d１に適合する縦リブ4b１と、ベース3の爪部3d２に連係する凸部4b２が設けられている。 Reference numeral 4 denotes a head that covers the upper portion of the base 3 so as to be slidable, and forms a storage space M (a space for sucking, pressurizing, and pumping the contents) M inside. The head 4 includes an annular inner wall 4a opened downward, an outer wall 4b surrounding the inner wall 4a and retaining the head 4 in the base 3, and a top wall 4c integrally connected to the upper ends of the inner wall 4a and the outer wall 4b. . On the inner surface of the outer wall 4b, there are provided vertical ribs 4b 1 adapted to the vertical grooves 3d 1 of the base 3 and convex portions 4b 2 linked to the claw portions 3d 2 of the base 3.

また、図における符号5はヘッド4につながるノズルである。このノズル5はヘッド4に一体につながる本体部分5aと、この本体部分5aにねじ止めあるいはアンダーカットによって係合させた先端部分5bからなり、その内側にはヘッド4の貯留空間につながる通路nが設けられている。通路nの内壁には内容物の流路断面を確保するため通路nに沿ってリブn１が形成され、ノズル5の先端部分5bは本体部分5aの軸芯L（図1参照）に対して角度θでもって斜め下向きの傾斜が付されている。 Reference numeral 5 in the figure is a nozzle connected to the head 4. The nozzle 5 includes a main body part 5a integrally connected to the head 4, and a tip part 5b engaged with the main body part 5a by screwing or undercut, and a passage n connected to a storage space of the head 4 is formed on the inner side thereof. Is provided. The inner wall of the passage n ribs n 1 along a path n order to ensure the flow cross-section of the contents is formed, the distal end portion 5b of the nozzle 5 with respect to the axis L of the body portion 5a (see FIG. 1) A slanting downward slope is given at an angle θ.

6はノズル5の通路n内の先端側に配置されたシャットオフピンである。このシャットオフピン6は通路nに設けられた段部e１（図3参照）と、シャットオフピン6の段部e２（図3参照）の相互間に配置されたスプリングSにより弾性支持されていて、ノズル5の先端部分5bに形成された噴出口5b１を常に閉塞する。 Reference numeral 6 denotes a shut-off pin disposed on the tip side in the passage n of the nozzle 5. The shut-off pin 6 and the stepped portion e 1 provided in the passage n (see FIG. 3), it is elastically supported by a spring S disposed between the mutually stepped portions e 2 of the shut-off pin 6 (see FIG. 3) The nozzle 5b 1 formed at the tip 5b of the nozzle 5 is always closed.

7は筒体3aの先端部分（上端部分）に一体的につながり貯留空間M内にて起立する切妻型の傾斜壁部である。この傾斜壁部７にはステム2ａ、逆止弁Cを通して吸引された内容物を貯留空間Mに流入させる経路を形成する開口7a(図2参照)が設けられている。   Reference numeral 7 denotes a gable-type inclined wall portion that is integrally connected to the distal end portion (upper end portion) of the cylindrical body 3a and stands up in the storage space M. The inclined wall portion 7 is provided with an opening 7a (see FIG. 2) that forms a path through which the content sucked through the stem 2a and the check valve C flows into the storage space M.

8はシャットオフピン6の後端部において一体的につながり、通路nを通して貯留空間Mに伸延する連結部材である。この連結部材8は貯留空間Mに位置する後端部位8aが該貯留空間Mを区画する天壁（あるいはリブ等）に当接するとともに傾斜壁部7に連係する開口8bが形成されており、ヘッド4を押し込んだ際に該開口8bの縁部が傾斜壁部7に沿って摺動し連結部材8を介してシャットオフピン6を後方へ向けてスライドさせることができるようになっている。   A connecting member 8 is integrally connected at the rear end of the shut-off pin 6 and extends into the storage space M through the passage n. The connecting member 8 has a rear end portion 8a located in the storage space M, which is in contact with a top wall (or rib or the like) that partitions the storage space M, and an opening 8b that is linked to the inclined wall portion 7 is formed. When 4 is pushed in, the edge of the opening 8b slides along the inclined wall portion 7 so that the shut-off pin 6 can be slid rearward through the connecting member 8.

内容物を噴出させるべくヘッド4を押し込むと、ヘッド4がベース3においてスライドする。このとき図3に示すように開口8bの縁部が傾斜壁部7に沿って摺動し連結部材8がシャットオフピン6とともにヘッド4の後方へ向けてスライドしノズル5の先端部分5bにおける噴出口5b１が開放されて内容物が外界へ向けて排出される。 When the head 4 is pushed in to eject the contents, the head 4 slides on the base 3. At this time, as shown in FIG. 3, the edge portion of the opening 8b slides along the inclined wall portion 7, the connecting member 8 slides toward the rear of the head 4 together with the shut-off pin 6, and the jet at the tip portion 5b of the nozzle 5 The outlet 5b 1 is opened and the contents are discharged toward the outside.

ヘッド4の押し込みにかかる力を解除すると、スプリングSの付勢力によりシャットオフピン6は噴出口5b１へ向けてスライドして該噴出口5b１を閉塞することとなりノズル5に噴出口5b１を斜め下向きに指向させる傾斜角度が付されていても液垂れが生じることがない。 When releasing the force on the pushing of the head 4, a shut-off pin 6 spout 5b 1 to nozzle 5 will be closed the該噴outlet 5b 1 slides toward the ejection outlet 5b 1 by the biasing force of the spring S No dripping occurs even if an inclination angle that is directed obliquely downward is applied.

連結部材8は基本的には単一部材にて構成するが、ノズル5の傾斜角度に適合（対応）する湾曲部8cを形成する場合には、その部位にインサート成形等により比較的軟質な部材（シャットオフピン6を前後にスライドさせることができる程度の剛性は必要）を適用するのがよい。   The connecting member 8 is basically composed of a single member, but when forming the curved portion 8c that matches (corresponds to) the inclination angle of the nozzle 5, it is a relatively soft member by insert molding or the like. (It is necessary to have enough rigidity to allow the shut-off pin 6 to slide back and forth).

図4は本発明にしたがう噴出ヘッドの他の実施の形態を示した図である。この例は筒体3aの先端部に図5に示すような片流れ型の傾斜壁部7を設け、ヘッド4の天面に蓋体9を備えた構成になるものであって、蓋体9の裏面には傾斜壁部7への接触を回避しつつ連結部材8の後端部位8ａに当接する一対の縦リブ9a、9bが形成されている。この蓋体9はアンダーカットの如き係合手段にてヘッド4の天面に連係保持される。   FIG. 4 is a view showing another embodiment of the ejection head according to the present invention. In this example, a cylindrical body 3a is provided with a single-flow type inclined wall portion 7 as shown in FIG. 5 and a top body of the head 4 with a lid body 9. A pair of vertical ribs 9a and 9b that contact the rear end portion 8a of the connecting member 8 while avoiding contact with the inclined wall portion 7 are formed on the back surface. The lid 9 is linked and held on the top surface of the head 4 by an engaging means such as an undercut.

かかる構成になる噴出ヘッドにおいても、図6に示す如く、ヘッド4の押し込みにより連結部材8の開口8bの縁部が傾斜壁部7に沿って摺動することとなり、この摺動により連結部材8がシャットオフピン6とともにヘッド4の後方へ向けてスライドしてノズル5の先端部分5bにおける噴出口5b１が開放されて内容物の排出が可能となる。 Also in the ejection head having such a configuration, as shown in FIG. 6, the edge of the opening 8b of the connecting member 8 slides along the inclined wall portion 7 by pushing the head 4, and this sliding causes the connecting member 8 to slide. There it is possible to discharge shutoff spout 5b 1 with pin 6 slides toward the rear of the head 4 at the tip portion 5b of the nozzle 5 is opened the contents.

天面壁4cが外壁4bの上端に一体連結する図1に示したようなヘッド4は、成形品を金型から引き抜く際に、外壁4bの下端部に設けた凸部4b２が金型に引っ掛かるため無理に引き抜かなければならず、その部位の成形性が劣ることとなっていたが、とくに、ヘッド4の天面に蓋体9を別途に設けた上掲図4に示すような構造のものにおいては、凸部4b２をかわす向きで金型から引き抜くことができるので、成形性を良好に維持できる利点がある。 In the head 4 as shown in FIG. 1 in which the top wall 4c is integrally connected to the upper end of the outer wall 4b, when the molded product is pulled out from the mold, the convex part 4b 2 provided at the lower end of the outer wall 4b is caught by the mold. Therefore, it had to be forcibly pulled out, and the formability of the part was inferior, but in particular, the structure as shown in Fig. 4 above provided with a lid 9 separately on the top surface of the head 4 Since it can be pulled out from the mold in a direction to dodge the convex portion 4b 2 , there is an advantage that the moldability can be maintained well.

シャットオフピン6の外周面には通路n内における配置姿勢を安定的に維持するため間隔をおいて複数枚のリブ6aを設けることができる（図6参照）。   A plurality of ribs 6a can be provided on the outer peripheral surface of the shut-off pin 6 at intervals in order to stably maintain the arrangement posture in the passage n (see FIG. 6).

ノズル5は本体部分5aと先端部分5bとの2部材にて構成した場合を例として示したがノズル5は単一部材にて構成してもよい。また、シャットオフノズル6の先端には噴出口5b１でのシール性を高めるため軟質材よりなるシールキャップ6b（図4参照）を設けることができる。 As an example, the nozzle 5 is composed of two members, ie, the main body portion 5a and the tip portion 5b. However, the nozzle 5 may be composed of a single member. Further, it is possible to provide a seal cap 6b made of soft material to enhance the sealing properties at ejection ports 5b 1 in the front end of the shut off nozzle 6 (see FIG. 4).

図1に示した連結部材8は開口部8bの縁部に傾斜壁部7と同じ傾きをもった傾斜面を形成し面同士で接触する場合を例として示したが、該連結部材8の開口部8bの縁部は図6に示したような接触形態（線接触）をとることも可能であり、この点については限定されない。   The connecting member 8 shown in FIG. 1 shows an example in which an inclined surface having the same inclination as the inclined wall portion 7 is formed at the edge of the opening 8b and the surfaces contact each other. The edge part of the part 8b can also take a contact form (line contact) as shown in FIG. 6, and this point is not limited.

液垂れが生じたり内容物の固化を伴うことのない噴出ヘッドが提供できる。   An ejection head that does not cause dripping or solidification of contents can be provided.
