Japanese Utility Model Publication No. 58-40008 Japanese Utility Model Publication No. 56-40324

しかしながら、特許文献１記載の塗布具は、塗布棒（１）に挿入口（４）を穿設し、該挿入口（４）に継手棒（３）を挿入取着するようにしているので、取付けのための工程が増加し、生産コストが高くつくという問題があった。
さらには、フレキシブルな線材として、金属を用い、簡単に取外しができないので、分別廃棄ができないという問題があった。 However, since the applicator described in Patent Document 1 has an insertion port (4) formed in the application rod (1) and the coupling rod (3) is inserted and attached to the insertion port (4), There was a problem that the process for mounting increased and the production cost was high.
Furthermore, since a metal is used as a flexible wire and cannot be easily removed, there is a problem that it cannot be disposed of separately.

また、特許文献２記載の塗布具は、容器に嵌着した小キャップ（６）に、楕円形状の挿入口（５）を形成し、塗布杆（２）の先端と刷毛部（３）の基部をそれぞれ楕円形状の長径部に合致させるようにしており、塗布杆引出しに注意を要し、さらに、しごき中栓がある場合には、刷毛部（３）を抜き出すときに、塗布杆（２）を傾斜させて抜き出さなければならないという問題があった。   Moreover, the applicator described in Patent Document 2 has an elliptical insertion port (5) formed in a small cap (6) fitted to a container, and the tip of the applicator (2) and the base of the brush part (3). Are matched with the long-diameter part of the ellipse, and care must be taken when pulling out the applicator. Further, when there is a squeezing inner plug, when removing the brush part (3), the applicator (2) There was a problem that it had to be tilted out.

本発明は、上記問題を解決することを課題とし、塗布部材本体と、塗布部材本体先端部に取着される軟材質を用いたブラシ部とからなる塗布部材を合成樹脂により形成し、塗布部材本体先端部とブラシ部を所望に応じて湾曲形成し、さらに、一定の弾性を持たせるようにしたマスカラ等の塗布具を提供することを目的とする。   An object of the present invention is to solve the above-mentioned problems, and an application member comprising an application member main body and a brush portion using a soft material attached to the front end portion of the application member main body is formed of a synthetic resin. An object of the present invention is to provide an applicator such as a mascara in which the tip of the main body and the brush part are curved as desired and have a certain elasticity.

本発明は、上記の課題を解決するため、塗布具として、容器本体と、塗布部材を取着したキャップとからなる合成樹脂製の塗布具であって、塗布部材が、塗布杆と塗布杆先端に連設され先端に傾斜するカット面を設けた弾性を有するシャフトとからなる塗布部材本体と、シャフトに取着される軟材質によって成形されたブラシ部とを具備しており、塗布部材の先端がブラシ部の射出成形時の射出圧力により、湾曲されて成形されていることを特徴とする構成を採用する。   In order to solve the above-mentioned problems, the present invention is a synthetic resin applicator comprising a container body and a cap with an applicator attached as an applicator, wherein the applicator comprises an applicator basket and a tip of the applicator hook And a brush portion formed of a soft material attached to the shaft, and a tip of the coating member. The configuration is characterized in that it is bent and molded by the injection pressure at the time of injection molding of the brush part.

塗布部材の成形方法として、先端に傾斜するカット面を形成したシャフトを具えた塗布部材本体のシャフトを金型内に挿入し、金型のゲートより加熱溶融したブラシ部の素材を一定の射出圧力で射出することで、素材のカット面に対する押圧力により、シャフトをカット面の反対側に湾曲変形させ、ブラシ部成形後、シャフトの復元力により、塗布部材の先端をカット面方向に湾曲させることを特徴とする構成を採用し、シャフトが、塗布部材に対して、同心に配設されていることを特徴とする構成、または、偏心して配設されていることを特徴とする構成を採用する。   As a method of forming the coating member, the brush member material, which is heated and melted from the mold gate, is inserted into the mold by inserting the shaft of the coating member body with a shaft having a cut surface inclined at the tip into the mold. The shaft is bent and deformed to the opposite side of the cut surface by the pressing force against the cut surface of the material, and the tip of the coating member is bent in the cut surface direction by the restoring force of the shaft after molding the brush part. The shaft is disposed concentrically with respect to the application member, or the shaft is disposed eccentrically. .

しごき中栓を取着した容器本体と、塗布部材を取着したキャップとからなる塗布具において、塗布部材を、先端に傾斜するカット面を設けた弾性を有するシャフトを形成した塗布部材本体を金型内にインサートし、シャフトに取着されるブラシ部を射出成形することによって形成したので、ブラシ部の射出成形時の射出圧力により、塗布部材の先端をカット面の傾斜方向に応じて湾曲させることができた。
また、ブラシ部を軟材質の素材を用いて成形したから、塗布部に対して十分に弾性を持つ塗布部材が得られるようになった。
さらにまた、容器自体を全て合成樹脂で形成できるため分別廃棄の必要がなくなった。 In an applicator consisting of a container main body with an ironing stopper and a cap with an applicator member, the applicator member is made of an applicator member body having an elastic shaft with a cut surface inclined at the tip. Since the brush part that is inserted into the mold and attached to the shaft is formed by injection molding, the tip of the coating member is curved according to the inclination direction of the cut surface by the injection pressure at the time of injection molding of the brush part. I was able to.
In addition, since the brush part is formed using a soft material, an application member having sufficient elasticity with respect to the application part can be obtained.
Furthermore, since the entire container itself can be made of a synthetic resin, there is no need for separate disposal.

次に、本発明の実施形態について、図面を参照して説明する。

ブラシ部Ｄ２は、図１に示すように、エラストマー等の軟材質を素材とし、射出成形により、塗布部材本体Ｄ１のシャフト２２を包み込むように成形され、シャフト２２とともに湾曲されるブラシ本体３０と、ブラシ本体３０の外周から放射状に突出した径が約０．１５〜０．３ｍｍの円形断面のブラシ毛３１とにより形成されている。   As shown in FIG. 1, the brush portion D2 is made of a soft material such as an elastomer, and is formed by wrapping the shaft 22 of the application member main body D1 by injection molding. It is formed by brush hairs 31 having a circular cross section with a diameter of about 0.15 to 0.3 mm protruding radially from the outer periphery of the brush body 30.

次に、本実施形態の使用態様と作用効果について説明する。
まず始めに、塗布部材Ｄの形成方法について説明する。
図３に示すように、上部にゲートＧを設けたブラシ部Ｄ２の金型Ｅの下方より、射出成形された塗布部材本体Ｄ１を、シャフト２２を上にして挿入する。 Next, usage modes and operational effects of the present embodiment will be described.
First, a method for forming the application member D will be described.
As shown in FIG. 3, the injection-molded application member body D1 is inserted with the shaft 22 facing upward from below the mold E of the brush part D2 provided with the gate G at the top.

次に、ゲートＧより、加熱溶融したブラシ部Ｄ２の素材Ｄ２ａを、一定の射出圧力で金型Ｅ内に射出する。
素材Ｄ２ａを一定の射出圧力で射出することにより、図４（ａ）に示すように、素材Ｄ２ａがまずシャフト２２のカット面２９上端に当接し、さらに下方に向かって押圧する。
カット面２９は傾斜しているため、素材Ｄ２ａの下方に向かっての押圧力が傾斜面を押圧することにより、傾斜面に対して直交方向への分力が働き、シャフト２２自体が金型Ｅの片側に押圧され、湾曲される。 Next, the raw material D2a of the heated and melted brush part D2 is injected from the gate G into the mold E with a constant injection pressure.
By injecting the material D2a at a constant injection pressure, as shown in FIG. 4A, the material D2a first comes into contact with the upper end of the cut surface 29 of the shaft 22 and further presses downward.
Since the cut surface 29 is inclined, the pressing force toward the lower side of the material D2a presses the inclined surface, whereby a component force in the direction orthogonal to the inclined surface acts, and the shaft 22 itself is the mold E. Is pressed to one side and curved.

ブラシ部Ｄ２の素材Ｄ２ａを射出後、図４（ｂ）に示すように、ブラシ部Ｄ２のシャフト２２からの厚さが厚い部分と薄い部分が成形される。
素材Ｄ２ａが冷却され、固化した後、金型Ｅから塗布部材Ｄを離型したときには、シャフト２２は、その剛性のため元の形に復元しようとするが、それに伴う軟材質のブラシ部Ｄ２のシャフト２２からの厚さにより、変形し易い部分と変形しにくい部分ができるため、シャフト２２の復元がある程度で阻止され、図４（ｃ）に示すように、シャフト２２およびブラシ部Ｄ２の形が片側に湾曲した塗布部材Ｄを得ることができる。 After injecting the raw material D2a of the brush part D2, as shown in FIG.4 (b), the thick part and thin part from the shaft 22 of the brush part D2 are shape | molded.
After the material D2a is cooled and solidified, when the coating member D is released from the mold E, the shaft 22 tries to restore its original shape due to its rigidity. Due to the thickness from the shaft 22, a portion that is easily deformed and a portion that is difficult to deform are formed, so that the restoration of the shaft 22 is prevented to some extent, and the shapes of the shaft 22 and the brush portion D <b> 2 are formed as shown in FIG. The application member D curved to one side can be obtained.

上記実施形態では、シャフト２２の形状を円柱状としたが、断面形状が角形や、半円形、三角形、コの字形などの形にすることにより、シャフトの変形しやすい方向を付与することができる。   In the above embodiment, the shape of the shaft 22 is a columnar shape. However, when the cross-sectional shape is a square shape, a semicircular shape, a triangular shape, a U-shaped shape, or the like, a direction in which the shaft can be easily deformed can be given. .

また、上記実施形態では、シャフト２２を塗布杆２１の中心に配設するようにしたが、塗布杆２１を偏心させて配設してもよい。
その場合には、図５に示すように、偏心させたシャフト２２の偏心側にカット面２９を形成させ、ブラシ部Ｄ２の素材Ｄ２ａの射出方向がカット面２９に直交する方向になるように、ゲートＧを配置する。
素材Ｄ２ａを射出することによって、シャフト２２を変形させることができる。 Moreover, in the said embodiment, although the shaft 22 was arrange | positioned in the center of the application basket 21, you may arrange | position the application basket 21 eccentrically.
In that case, as shown in FIG. 5, the cut surface 29 is formed on the eccentric side of the eccentric shaft 22, and the injection direction of the material D2a of the brush portion D2 is orthogonal to the cut surface 29. A gate G is disposed.
The shaft 22 can be deformed by injecting the material D2a.

次に、上記構成による作用効果について説明する。
マスカラの使用態様は従来のものと同様であり、ブラシ部Ｄ２を容器本体Ａから抜き出すとき、しごき中栓Ｂのワイパー７によってブラシ部Ｄ２への容器本体Ａ内のマスカラの付着量が調整されるが、その際、容器の軸心に対して塗布部材Ｄの塗布部材本体Ｄ１およびブラシ部Ｄ２の抜け出し方向が一致していなくても、塗布杆２１およびシャフト２２がしなるので、難なく抜け出すことができる。 Next, the function and effect of the above configuration will be described.
The usage mode of the mascara is the same as the conventional one. When the brush part D2 is extracted from the container main body A, the amount of mascara in the container main body A to the brush part D2 is adjusted by the wiper 7 of the ironing plug B. However, at that time, even if the application member body D1 and the brush part D2 of the application member D do not coincide with the axial direction of the container, the application basket 21 and the shaft 22 are bent, so that the application member D1 and the brush 22 can be extracted without difficulty. it can.

まつげへの塗布にあたっては、塗布部材Ｄのシャフト２２がしなるので、ブラシ部Ｄ２をまつげに一様に押さえつけて塗布することができる。
また、ブラシ部Ｄ２が湾曲しているので、一層使いやすくなっている。 In application to the eyelashes, since the shaft 22 of the application member D is bent, the brush part D2 can be uniformly pressed onto the eyelashes for application.
Further, since the brush part D2 is curved, it is easier to use.

さらにまた、塗布部材Ｄの嵌合筒部２０の位置合せリブ２５方向に、塗布部材Ｄの先端を湾曲することができるので、位置合せリブ２５と嵌合するキャップＣ内周の縦溝１５の位置に合わせて、キャップＣ外周の任意の位置に位置合せマークを設けることで、塗布具を開蓋しなくてもキャップＣの位置合せマークにより、塗布部材Ｄの先端の湾曲方向を知ることができる。   Furthermore, since the tip of the application member D can be curved in the direction of the alignment rib 25 of the fitting cylinder portion 20 of the application member D, the longitudinal groove 15 on the inner periphery of the cap C that fits the alignment rib 25 According to the position, by providing an alignment mark at an arbitrary position on the outer periphery of the cap C, the bending direction of the tip of the application member D can be known by the alignment mark of the cap C without opening the applicator. it can.

塗布部材のシャフトの先端に設けた傾斜するカット面と、ブラシ部の射出成形時の射出圧力により、塗布部材の先端を湾曲させ、さらに塗布部に対して十分に弾性を持つ塗布部材を安価で形成でき、さらに、容器自体を全て合成樹脂で形成できるため、分別廃棄の必要がなくなった。
また、マスカラ塗布具の塗布部材の先端がしなるようにしたことから、マスカラ塗布具ばかりではなく、ブラシ等を使用する毛染剤や、薬液の塗布具等にも適用できるようになった。 By applying the inclined cut surface provided at the tip of the shaft of the coating member and the injection pressure at the time of injection molding of the brush part, the tip of the coating member is curved and the coating member having sufficient elasticity with respect to the coating part is inexpensive. In addition, since the entire container itself can be formed of a synthetic resin, there is no need for separate disposal.
Further, since the tip of the applicator member of the mascara applicator is bent, the applicator can be applied not only to the mascara applicator but also to a hair dye using a brush or the like, an applicator for a chemical solution, or the like.

さらに、塗布部材の先端が軟材質のブラシ部で、肌にソフトに接触するので、アイシャドー等の塗布具にも適用できる。   Furthermore, since the tip of the application member is a soft material brush portion that comes into soft contact with the skin, it can be applied to an applicator such as an eye shadow.
