図１に示すように、押下ヘッド１は、上方付勢状態で押し込み可能にステム３（図２参照）を起立した吐出器５に装着されており、吐出器５は、容器７の口部７ａに固定されている。図２に詳細を示すように、吐出器５は、ここではポンプ式を採用し、容器７の口部７ａを通して充填空間Ｍの上部に吊り下げ保持されている。この吐出器５は、最下端に吸引口（図示省略）を有するシリンダ５ａと、このシリンダ５ａ内で上下にスライド可能で、容器７の口部７ａに着脱自在にねじ止めされた筒状のベースキャップ５ｂの貫通孔５ｃから露出させたステム３と、ステム３の内側に連結され、該ステム３とともにスライド可能なガイド５ｄと、このガイド５ｄ及びステム３の相互間でスライド代をもって配置され、該ガイド５ｄと協働して吐出弁を構成するピストン５ｅと、シリンダ５ａ内で上記吸引口の開閉を行うポペット（バルブ）５ｆを有する。また、ベースキャップ５ｂの上面５ｇには、押下ヘッド１の後述する周壁部１７との間に若干の隙間をもって上方に向けて延びるガイド壁５ｈが設けられ、押下ヘッド１の上下移動が安定して行えるようになっている。   As shown in FIG. 1, the pressing head 1 is mounted on a discharger 5 in which a stem 3 (see FIG. 2) is erected so that it can be pushed in an upward biased state. It is fixed to. As shown in detail in FIG. 2, the discharger 5 adopts a pump type here, and is suspended and held on the upper portion of the filling space M through the mouth portion 7 a of the container 7. The discharger 5 includes a cylinder 5a having a suction port (not shown) at the lowermost end, and a cylindrical base that is slidable up and down within the cylinder 5a and is detachably screwed to the mouth 7a of the container 7. A stem 3 exposed from the through-hole 5c of the cap 5b, a guide 5d connected to the inside of the stem 3 and slidable together with the stem 3, and arranged with a sliding margin between the guide 5d and the stem 3, It has a piston 5e that constitutes a discharge valve in cooperation with the guide 5d, and a poppet (valve) 5f that opens and closes the suction port in the cylinder 5a. Further, a guide wall 5h extending upward with a slight gap is provided on the upper surface 5g of the base cap 5b with a peripheral wall portion 17 to be described later of the pressing head 1 so that the vertical movement of the pressing head 1 is stabilized. It can be done.

なお、吐出器５の形態は、ステム３を押下げることにより容器７内の液状物がステム３より吐出するよう構成したものであれば採用でき、上述したポンプ構造を備えたものの他、エアゾールタイプのもの等（図示省略）も採用できる。   In addition, the form of the discharge device 5 can be adopted as long as the liquid material in the container 7 is discharged from the stem 3 by pushing down the stem 3, and in addition to the above-described pump structure, an aerosol type (Not shown) can also be employed.

押下ヘッド１は、吐出器５のステム３に連通するノズル孔９を内部に有するものであり、ステム３に装着される筒状の装着部１１を垂設する頂壁部１３と、頂壁部１３の外周縁部から下方に向けて延設されるとともにノズル孔９の一端を開口して噴出口１５を形成する円筒状の周壁部１７と、を有する。また、頂壁部１３の外面１３ａは押下ヘッド１の押下操作時に指を掛ける指掛かり部となる部位であり、その外周縁部には上方に向けて延設されたへら状の塗布具１９が一体に成形されている。   The press-down head 1 has a nozzle hole 9 communicating with the stem 3 of the discharger 5 inside, and a top wall portion 13 that vertically mounts a cylindrical mounting portion 11 that is mounted on the stem 3, and a top wall portion 13 has a cylindrical peripheral wall portion 17 extending downward from the outer peripheral edge portion 13 and opening one end of the nozzle hole 9 to form a jet port 15. Further, the outer surface 13a of the top wall portion 13 is a portion that becomes a finger hooking portion for hooking a finger when the pressing head 1 is pressed, and a spatula-shaped applicator 19 extending upward is provided on the outer peripheral edge thereof. It is molded integrally.

塗布具１９は、外周縁部に沿って部分的に設けることとし、これにより押下ヘッド１を押し下げる際に指を頂壁部１３に導く空間部を押下ヘッド１の後方側（図２では右側）に形成している。ここでは塗布具１９は、噴出口１５が配置された側である押下ヘッド１の前方側（図２では左側）に配置されており、すなわち噴出口１５の上方に配置されている。また、塗布具１９はその先端形状が丸みを帯びた湾曲形状としている。塗布具１９の先端部域の前面には、少なくとも１つ（ここでは５つ）のドーム状の突起２１が一体に設けられており、さらに塗布具１９の先端縁部にも上方に突出する複数の突起２３が設けられている。なおこれらの突起２１、２３の形状は図示例のものに限らず、種々の形状を採用でき、例えば突起２１、２３をゴム材料で形成するとともに先細り形状としてもよく、これによれば口述する突起２１、２３によるマッサージ効果を高めることが可能である。しかも、頂壁部１３の外面１３ａと、塗布具１９の背面１９ａとは、下方に向けて凹となる曲面Ｒにて連結され、つまり屈折点を有することなく滑らかに連結されている。   The applicator 19 is partially provided along the outer peripheral edge, and thereby the space that guides the finger to the top wall 13 when the pressing head 1 is pressed down is the rear side of the pressing head 1 (the right side in FIG. 2). Is formed. Here, the applicator 19 is disposed on the front side (left side in FIG. 2) of the pressing head 1 that is the side on which the ejection port 15 is disposed, that is, disposed above the ejection port 15. The applicator 19 has a curved shape with a rounded tip. At least one (here, five) dome-shaped protrusions 21 are integrally provided on the front surface of the distal end region of the applicator 19, and a plurality of protrusions projecting upward also at the distal end edge of the applicator 19. The protrusion 23 is provided. The shapes of the protrusions 21 and 23 are not limited to those shown in the drawings, and various shapes can be employed. For example, the protrusions 21 and 23 may be formed of a rubber material and may have a tapered shape. The massage effect by 21 and 23 can be enhanced. Moreover, the outer surface 13a of the top wall portion 13 and the back surface 19a of the applicator 19 are connected by a curved surface R that is concave downward, that is, smoothly connected without having a refraction point.

かかる実施形態の押下ヘッド１によれば、押下ヘッド１の頂壁部１３にへら状の塗布具１９が一体に設けられているので、対象物に噴射した後、液状物を塗り付けたり塗り広げたり、あるいはマッサージをするに際して、効率的に行い得て使い勝手がよい。また、部品点数も削減できる。   According to the pressing head 1 of this embodiment, since the spatula-shaped applicator 19 is integrally provided on the top wall portion 13 of the pressing head 1, the liquid material is applied or spread after being sprayed onto the object. It is efficient and easy to use when performing massages or massages. In addition, the number of parts can be reduced.

また、塗布具１９が、噴出口１５が配置された側である押下ヘッド１の前方側に配置されているため、押下ヘッド１を操作したときの姿勢のままで塗布することができ、より自然な姿勢でかつ容易に塗布作業が行えるようになる。さらに、塗布具１９の先端部域の前面には、突起２１が一体に設けられており、塗布具１９の先端縁部にも上方に突出する突起２３が設けられていることから、特に育毛剤などを頭皮に噴射した後のマッサージも有利に行えるようになる。しかも、頂壁部１３の外面１３ａと塗布具１９の背面１９ａとが、下方に凹の曲面Ｒにて連結されているので、頂壁部１３の外面１３ａ及び塗布具１９の背面１９ａと指との接触面積が増えてより安定して押下ヘッド１の押下操作や塗布具１９による塗布作業を行うことが可能となる。   In addition, since the applicator 19 is disposed on the front side of the pressing head 1 that is the side on which the spout 15 is disposed, the applicator 19 can be applied while maintaining the posture when the pressing head 1 is operated. The application operation can be easily performed in a proper posture. Further, since the protrusion 21 is integrally provided on the front surface of the distal end region of the applicator 19, and the protrusion 23 that protrudes upward is also provided on the front edge of the applicator 19, the hair restorer is particularly useful. Massage after spraying etc. on the scalp can be performed advantageously. Moreover, since the outer surface 13a of the top wall portion 13 and the back surface 19a of the applicator 19 are connected to each other by a concave curved surface R, the outer surface 13a of the top wall portion 13 and the back surface 19a of the applicator 19 and the finger Thus, the pressing operation of the pressing head 1 and the application work by the applicator 19 can be performed more stably.

図３は、この発明の押下ヘッド付き吐出器に好適に用いることができるカバーを示す斜視図であり、図４は、図３のカバーを適用した押下ヘッド付き吐出器を示す断面図である。   FIG. 3 is a perspective view showing a cover that can be suitably used for the discharger with a pressing head of the present invention, and FIG. 4 is a cross-sectional view showing the discharger with a pressing head to which the cover of FIG. 3 is applied.

図３に示すカバー２５は、上壁部２７と側壁部２９とを有するとともに、側壁部２９の後方部が大きく切り欠かれており、これにより押下ヘッド１を備えた吐出器５に前方（図４の左側）から着脱自在に装着できる。また、側壁部２９の下端部の両側縁には、カバー２５の装着時にベースキャップ５ｂのガイド壁５ｈの外周を覆ってカバー２５の脱落を防止する囲い壁３０をそれぞれ設けている。したがって、カバー２５を装着する際には、囲い壁３０を若干外側に押し広げた状態にて押下ヘッド付き吐出器５に横（前方）から被せるようにする。カバー２５の下端縁は、カバー装着時に吐出器５に当接することが好ましく、これによれば、カバー２５上部内面と押下ヘッド１の先端縁部との間に隙間を形成、保持でき、ここでは該下端縁は吐出器５のベースキャップ５ｂの上面５ｇに当接するよう構成されている。また、カバー２５は、その内面に、カバー装着時にて押下ヘッド１の噴出口１５に対向して位置して該噴出口１５を密封する凸部３１を有する。   The cover 25 shown in FIG. 3 has an upper wall portion 27 and a side wall portion 29, and a rear portion of the side wall portion 29 is greatly cut away, so that a front side (see FIG. 4 can be detachably mounted. Enclosure walls 30 that cover the outer periphery of the guide wall 5 h of the base cap 5 b and prevent the cover 25 from falling off are provided on both side edges of the lower end portion of the side wall portion 29 when the cover 25 is attached. Therefore, when the cover 25 is mounted, the discharger 5 with the pressing head is covered from the side (front) in a state where the surrounding wall 30 is slightly expanded outward. The lower end edge of the cover 25 is preferably in contact with the dispenser 5 when the cover is mounted. According to this, a gap can be formed and held between the upper inner surface of the cover 25 and the tip end edge of the pressing head 1. The lower end edge is configured to contact the upper surface 5g of the base cap 5b of the discharger 5. Further, the cover 25 has a convex portion 31 on the inner surface thereof, which is located opposite to the ejection port 15 of the pressing head 1 and seals the ejection port 15 when the cover is mounted.

このようなカバー２５を用いることにより、塗布具１９を用いた塗布作業後に液状物が塗布具１９に付着していてもカバー２５で押下ヘッド１全体を覆うことができ、塗布具１９に付着した液状物が他の物に付くことがないので携帯するのに便利であり、また塗布具１９に埃等が付着するおそれもない。また、押下ヘッド１のノズル孔９内に液状物が残留している場合であっても、カバー２５の凸部３１によって噴出口１５が密封されていることから、これが外部に漏れ出すおそれもない。   By using such a cover 25, the entire pressing head 1 can be covered with the cover 25 even if a liquid material adheres to the applicator 19 after the application operation using the applicator 19. Since the liquid material does not adhere to other objects, it is convenient to carry, and there is no possibility that dust or the like adheres to the applicator 19. Further, even when a liquid material remains in the nozzle hole 9 of the pressing head 1, since the ejection port 15 is sealed by the convex portion 31 of the cover 25, there is no possibility that this will leak to the outside. .

また、カバー２５は、その下端部内面に、カバー装着時にて押下ヘッド１の下端縁１ａに当接して吐出器５に対する該押下ヘッド１の押し下げを阻止するリブ状の突起３３を少なくとも１つ（ここでは３つ）有する。これにより、誤って押下ヘッド１を操作した場合であっても液状物が噴出するおそれがない。また、これらの突起３３を吐出器５のベースキャップ５ｂの上面５ｇと押下ヘッド１の下端縁との間に挟持させることによって、カバー２５の脱落をより一層防止することができる。なお、突起３３に代えて囲い壁３０の径を図示のものよりも小さくし、囲い壁３０を押下ヘッド１の下端縁１ａとベースキャップ５ｂの上面５ｇとの間に嵌め込むことにより、押下ヘッド１の押し下げを阻止するようにしてもよい。   Further, the cover 25 has at least one rib-like protrusion 33 on the inner surface of the lower end portion thereof, which is in contact with the lower end edge 1a of the pressing head 1 and prevents the pressing head 1 from being pushed down when the cover is mounted ( There are three). Thereby, even if it is a case where the pressing head 1 is operated accidentally, there is no possibility that a liquid substance may be ejected. Further, by holding these protrusions 33 between the upper surface 5g of the base cap 5b of the discharger 5 and the lower end edge of the pressing head 1, the cover 25 can be further prevented from falling off. The diameter of the surrounding wall 30 is made smaller than that shown in the drawing instead of the protrusion 33, and the pressing wall is fitted between the lower end edge 1a of the pressing head 1 and the upper surface 5g of the base cap 5b. 1 may be prevented from being pushed down.

かくしてこの発明により、対象物に噴射した液状物を塗り付けたり塗り広げたり、あるいはマッサージをするに際して、押下ヘッドと一体構造の塗布部材を使用できる押下ヘッド及び押下ヘッド付き吐出器が提供される。   Thus, according to the present invention, there are provided a pressing head and a discharger with a pressing head, which can use an application member integrated with the pressing head when applying, spreading, or massaging a liquid material sprayed onto an object.
