Description

本発明は化粧料用塗布具に関し、特にブリッスルコームの構造に関するものである。   The present invention relates to a cosmetic applicator, and more particularly to the structure of a bristle comb.

従来、マスカラ液を睫毛に塗布する際に使用する塗布具として、円柱状の軸の先端外周面に、睫毛にマスカラ液を塗布するための例えばブラシ状や溝状等で構成された塗布部を備え、さらにこの塗布部と軸を介して反対側の先端外周面に、塗布部によってマスカラ液が塗布された睫毛に対して、マスカラ液の固まりである、いわゆる「だま」を取ったり、互いにくっついてしまった睫毛を一本一本捌いたりするための複数のブリッスルを有するコーム部を備えたものがある（例えば特許文献１）。   Conventionally, as an applicator used when applying mascara liquid to eyelashes, an applicator configured by, for example, a brush shape or a groove shape for applying mascara liquid to eyelashes on the tip outer peripheral surface of a cylindrical shaft is provided. In addition, on the outer peripheral surface of the tip opposite to the application part and the shaft, the soot that is a mass of the mascara liquid is applied to the eyelashes to which the mascara liquid is applied by the application part, or sticks to each other There is a thing provided with the comb part which has a plurality of bristle for carrying out the eyelashes which have become one by one (for example, patent documents 1).

このような塗布具は、通常、容器本体に収容されたマスカラ液に軸の先端部が浸漬された状態で密閉されており、睫毛にマスカラ液を塗布する際には、容器本体からマスカラ液が付着した軸の先端部を引き抜くときに、容器本体に形成された扱き部材によってマスカラ液の付着量を調整してから使用している。
特開２００６−９５０９１号公報 Such an applicator is normally sealed with the tip of the shaft immersed in the mascara liquid contained in the container body, and when the mascara liquid is applied to the eyelashes, the mascara liquid is removed from the container body. When the tip end of the attached shaft is pulled out, it is used after adjusting the amount of mascara liquid attached by a handling member formed on the container body.

In the present embodiment, a mascara applicator is described as an example of a cosmetic applicator, but the present invention is not limited to this, and can be applied to, for example, an eyebrow applicator applied to eyebrows. 1 is a side view of the mascara applicator 1 of the present embodiment, FIG. 2 is an exploded view of FIG. 1, FIG. 3 is a cross-sectional perspective view taken along line AA of FIG. 1, and FIG. FIG. 5 shows another embodiment of the bristle, and FIG. 6 shows a view of pulling out the tip of the mascara applicator 1 from the container body. In FIG. 1 to FIG. 4, the side where the tip of the bristle 3 a is located, that is, the upper side on the paper surface will be described below for convenience.

本実施形態のマスカラ塗布具１は、図１に示す如く、軸部２と、コーム部３と、塗布部４とキャップ５とを備えている。   As shown in FIG. 1, the mascara applicator 1 of this embodiment includes a shaft portion 2, a comb portion 3, an applicator portion 4, and a cap 5.

軸部２は、図２に示す如く、略円柱状の軸本体２ａを備えてなり、該軸本体２ａの先端側には長手方向に沿って開口し後述の塗布部４が装着される開口部２ｂと、開口部２ｂと連通し、図３に示す如く、後述のコーム部３の基台部材３ｂが装着される装着部２ｃと有し、さらに装着部２ｃと連通し、軸本体２ａの先端部の外周面に長手方向に沿って延びるスリット２ｄを有している。 As shown in FIG. 2, the shaft portion 2 includes a substantially cylindrical shaft body 2 a, and an opening portion that opens along the longitudinal direction at the distal end side of the shaft body 2 a and is attached with a coating portion 4 described later. 2b and an opening 2b, and as shown in FIG. 3, it has a mounting part 2c to which a base member 3b of a comb part 3 to be described later is mounted, and further communicates with the mounting part 2c to connect the tip of the shaft body 2a. A slit 2d extending along the longitudinal direction is provided on the outer peripheral surface of the portion.

スリット２ｄの深さｄは、［発明が解決しようとする課題］で説明した扱き部材６（図１２参照）が形成された容器本体（図示せず）にマスカラ塗布具１の先端側を１００回出し入れしたときの後述するブリッスル３ａにおいて、ｄが０．２ｍｍのときは若干散けが生じ、ｄが０．５ｍｍのときは散けが生じなかったので、０．５ｍｍ以上であることが好ましく、軸本体２ａの径が大きくなりすぎないように２ｍｍ以下であることが好ましい。従ってスリット２ｄの深さｄは０．５〜２ｍｍの範囲、本実施形態では０．５ｍｍで形成されている。 The depth d of the slit 2d is 100 times the tip side of the mascara applicator 1 on the container body (not shown) in which the handling member 6 (see FIG. 12) described in [Problems to be Solved by the Invention] is formed. In the bristle 3a, which will be described later, when the d is 0.2 mm, there is some scattering, and when d is 0.5 mm, no scattering occurs, so that it is preferably 0.5 mm or more. It is preferable that it is 2 mm or less so that the diameter of 2a does not become too large. Accordingly, the depth d of the slit 2d is in the range of 0.5 to 2 mm, in this embodiment, 0.5 mm.

また軸本体２ａの後端にはマスカラ液を収容した容器本体（図示せず）の開口部に開閉自在に装着されるキャップ５が連結されており、このキャップ５はユーザが把持する取っ手として使用可能に構成されている。なおこの容器本体に、上記扱き部材６（図１２参照）が形成されている。   A cap 5 that can be opened and closed is connected to the rear end of the shaft main body 2a in an opening of a container main body (not shown) containing mascara liquid. The cap 5 is used as a handle to be held by a user. It is configured to be possible. The handling member 6 (see FIG. 12) is formed on the container body.

そして軸部２は、ＰＢＴ（ポリブチレンテレフタレート）、ＰＡ（ポリアミド）、ＰＰ（ポリプロピレン）のいずれか１つを主成分として例えば射出成形等により形成されており、材質は化粧料の成分に応じて適宜選定される。   The shaft portion 2 is formed by, for example, injection molding or the like with any one of PBT (polybutylene terephthalate), PA (polyamide), and PP (polypropylene) as a main component, and the material depends on the cosmetic ingredients. It is selected appropriately.

コーム部３は、マスカラ液が塗布された睫毛に対して、マスカラ液の固まりである、いわゆる「だま」を取ったり、互いにくっついてしまった睫毛を一本一本捌いたりするためのものであり、ポリエステル系の熱可塑性エラストマー（ＴＰＥ：Thermoplastic Elastomer）を主成分として例えば射出成形等により形成されており、射出・押出・ブローなどの成形加工の容易性や耐疲労性、耐薬品性、ゴムとエンプラ両方の特性を有すること等から、具体的には東洋紡績株式会社製ペルプレン（登録商標）Ｐ−２８０Ｂ及び／又はＥ−４５０Ｂを材料として使用している。なおコーム部３に使用する材料については後で詳細に説明する。   The comb part 3 is for removing the so-called “dama”, which is a lump of mascara liquid, for the eyelashes to which the mascara liquid has been applied, or for spreading the eyelashes that have stuck together one by one. It is made of polyester thermoplastic elastomer (TPE: Thermoplastic Elastomer) as a main component, for example, by injection molding, etc., and is easy to injection, extrusion, blow, etc., fatigue resistance, chemical resistance, rubber Since it has the characteristics of both engineering plastics, specifically, Toyobo Co., Ltd. Perprene (registered trademark) P-280B and / or E-450B is used as a material. The material used for the comb portion 3 will be described in detail later.

そしてコーム部３は、図１〜図３に示す如く、長手方向に一列に配列された複数のブリッスル３ａと、この複数のブリッスル３ａが垂直に配列され、かつ複数のブリッスル３ａの基部を保持する、直方体で構成された基台部材３ｂとで構成されている。   As shown in FIGS. 1 to 3, the comb portion 3 has a plurality of bristles 3a arranged in a line in the longitudinal direction, the plurality of bristles 3a arranged vertically, and holds the bases of the plurality of bristles 3a. The base member 3b is a rectangular parallelepiped.

複数のブリッスル３ａは、図４に示す如く、各ブリッスル３ａの断面が例えば直径Ａ１＝０．２ｍｍの円状に形成され、全長Ｌが、長すぎると成形品の一部に樹脂が回らずに成形品の一部が欠ける現象いわゆるショートモールドとなるため、マスカラ塗布具１の径の制約から成形が困難であり、短すぎると睫毛に届かなくなり使用性が低下するため、３〜６ｍｍで形成されている。   As shown in FIG. 4, the cross-section of each bristle 3a is formed in a circular shape with a diameter A1 = 0.2 mm, for example, and if the total length L is too long, the resin does not turn around a part of the molded product. A phenomenon in which a part of the molded product is missing becomes a so-called short mold, so it is difficult to mold due to the restriction of the diameter of the mascara applicator 1, and if it is too short, it will not reach the eyelashes and the usability will be reduced. ing.

そして、図４に示す如く、長手方向における各ブリッスル３ａの間隙Ｄは、０．１〜２．０ｍｍで形成され、好ましくは０．２±０．０２ｍｍで形成されている。こうすることにより、個人差はあるものの一般的に人の睫毛の太さが０．１５ｍｍ程度であるため、コーム部３によって睫毛を捌くときに、ブリッスル３ａの間隙Ｄに睫毛が１本のみしか入らないので、睫毛を一本一本捌くことができる。   And as shown in FIG. 4, the gap | interval D of each bristle 3a in a longitudinal direction is formed by 0.1-2.0 mm, Preferably it is formed by 0.2 +/- 0.02 mm. In this way, although there are individual differences, the thickness of a person's eyelashes is generally about 0.15 mm, so when combing the eyelashes with the comb portion 3, only one eyelash is in the gap D of the bristle 3a. Because it does not enter, you can comb the eyelashes one by one.

なお本実施形態のブリッスル３ａは、上述のように断面が円状に形成されたものとしたが、本発明はこれに限られるものではなく、複数のブリッスル３ａの配列方向と略直角方向すなわち塗布方向に幅を持たせてもよいし、図５（ａ）に示す如く、例えば前記幅Ａ２が０．２ｍｍ、この幅と略直角方向の幅Ａ３が０．３ｍｍ又は０．４ｍｍの角丸形状の断面を有するブリッスルであっても、図５（ｂ）に示す如く、例えば上記と同様の寸法の楕円形状の断面を有するブリッスルであってもよく、ひし形や三角形の断面を有するブリッスルであってもよい。   The bristle 3a of the present embodiment has a circular cross section as described above. However, the present invention is not limited to this, and a direction substantially perpendicular to the arrangement direction of the plurality of bristle 3a, i.e., coating. As shown in FIG. 5A, for example, the width A2 is 0.2 mm, and the width A3 in a direction substantially perpendicular to the width is 0.3 mm or 0.4 mm. 5B, for example, a bristle having an elliptical cross section having the same dimensions as described above may be used, and a bristle having a diamond or triangular cross section may be used. Also good.

また本実施形態のブリッスル３ａは上端から下端まで断面形状が変わらないストレート形状としたが、本発明はこれに限られるものではなく、先鋭形状に形成されたテーパーを有するブリッスルであってもよい。   Moreover, although the bristle 3a of this embodiment was made into the straight shape whose cross-sectional shape does not change from an upper end to a lower end, this invention is not limited to this, The bristle which has the taper formed in the acute shape may be sufficient.

塗布部４は、睫毛にマスカラ液を塗布するためのものであり、ＰＢＴ（ポリブチレンテレフタレート）、ＰＡ（ポリアミド）、ＰＰ（ポリプロピレン）のいずれか１つを主成分として例えば射出成形等により形成されており、材質は化粧料の成分に応じて適宜選定される。   The application part 4 is for applying mascara liquid to the eyelashes, and is formed by, for example, injection molding with one of PBT (polybutylene terephthalate), PA (polyamide), and PP (polypropylene) as a main component. The material is appropriately selected according to the cosmetic ingredients.

そして塗布部４は、図３に示す如く、断面が略半円状であって、図１及び図２に示す如く、軸本体２の開口部２ｂに装着可能な長さで長手方向に延びて形成されている。そして塗布部４の下端には、図３に示す如く、長手方向と略直角方向に周面に沿って形成された塗布溝４ａが、長手方向に沿って複数配列されている。また塗布部４の上端には、上面から突出した凸部４ｂが、長手方向に沿って１つ以上形成されている。   The application section 4 has a substantially semicircular cross section as shown in FIG. 3, and extends in the longitudinal direction with a length that can be attached to the opening 2b of the shaft body 2 as shown in FIGS. Is formed. As shown in FIG. 3, a plurality of coating grooves 4a formed along the circumferential surface in a direction substantially perpendicular to the longitudinal direction are arranged at the lower end of the coating part 4 along the longitudinal direction. Further, at the upper end of the application part 4, one or more convex parts 4b protruding from the upper surface are formed along the longitudinal direction.

次に上述の軸部２、コーム部３、塗布部４の組付方法について説明する。先ず、図３に示す如く、複数のブリッスル３ａが軸本体２ａのスリット２ｄの内部から軸本体２ａの外周面を越えて突出するように、軸本体２ａの下側からコーム部３の基台部材３ｂを装着部２ｃに挿入し、各ブリッスル３ａの基端が軸本体２ａの外周面よりも低い所に位置するようにする。このとき図３に示す如く、スリット２ｄの深さｄが０．５ｍｍであり、基台部材３ｂの上面が装着部２ｃの上面に当接するので、各ブリッスル３ａの基端から軸本体２ａの外周面までの距離は０．５ｍｍとなる。 Next, a method for assembling the shaft part 2, the comb part 3, and the application part 4 will be described. First, as shown in FIG. 3, the base member of the comb portion 3 from the lower side of the shaft body 2a so that the plurality of bristles 3a protrude from the inside of the slit 2d of the shaft body 2a beyond the outer peripheral surface of the shaft body 2a. 3b is inserted into the mounting portion 2c so that the base end of each bristle 3a is positioned lower than the outer peripheral surface of the shaft body 2a. At this time, as shown in FIG. 3, the depth d of the slit 2d is 0.5 mm, and the upper surface of the base member 3b comes into contact with the upper surface of the mounting portion 2c. The distance to the surface is 0.5 mm.

このように各ブリッスル３ａの基端が軸本体２ａの外周面よりも低い所に位置することにより、図６に示す如く、容器本体からマスカラ液が付着した軸部２の先端部を引き抜くときに扱き部材６の扱き口６ａに各ブリッスル３ａの基端が当接しないので、ブリッスル３ａの基端にかかる負荷を低減することができる。   Thus, when the base end of each bristle 3a is positioned lower than the outer peripheral surface of the shaft body 2a, as shown in FIG. 6, when the distal end portion of the shaft portion 2 to which the mascara liquid adheres is pulled out from the container body. Since the base end of each bristle 3a does not contact the handling port 6a of the handling member 6, the load applied to the base end of the bristle 3a can be reduced.

これにより容器本体から軸部２を引き抜く際に、扱き部材６によってブリッスル３ａが互い違いに根元から曲がるのを防ぐことができるので、ブリッスル３ａが散けて広がるのを防止することができる。   Thereby, when pulling out the shaft part 2 from the container main body, the bristle 3a can be prevented from being bent alternately from the root by the handling member 6, so that the bristle 3a can be prevented from spreading and spreading.

次に塗布部４を、凸部４ｂを上側にして軸部２の下側から開口部２ｂに装着する。ことのき塗布部４と軸本体２ａとは、例えば凹凸状にそれぞれ形成されて互いに係合する係合部（図示せず）により着脱可能に固定されている。なお塗布部４と軸本体２ａとは、さらに超音波溶着や高周波溶着等によって溶着してもよい。そしてコーム部３は、図３に示す如く、基台部材３ｂの上面が装着部２ｃの上面に当接し、下面が凸部４ｂの上端に当接されて、軸本体２ａ及び塗布部４によって上下両側から把持される。本実施形態のマスカラ塗布具１は上述のようにして組み付けられる。   Next, the application part 4 is attached to the opening 2b from the lower side of the shaft part 2 with the convex part 4b facing upward. For example, the application portion 4 and the shaft body 2a are detachably fixed by engaging portions (not shown) that are respectively formed in an uneven shape and engage with each other. The application unit 4 and the shaft body 2a may be further welded by ultrasonic welding, high frequency welding, or the like. As shown in FIG. 3, the comb portion 3 has an upper surface of the base member 3b abutted against the upper surface of the mounting portion 2c and a lower surface abutted with the upper end of the convex portion 4b. It is gripped from both sides. The mascara applicator 1 of this embodiment is assembled as described above.

上述のように構成された本実施形態のマスカラ塗布具１によれば、各ブリッスル３ａの基端が軸本体２ａの外周面よりも低い所に位置することができて、容器本体からマスカラ液が付着した軸部２の先端部を引き抜くときに容器本体に形成された扱き部材６の扱き口６ａに各ブリッスル３ａの基端が当接しないので、ブリッスル３ａの基端にかかる負荷を低減することができる。   According to the mascara applicator 1 of the present embodiment configured as described above, the base end of each bristle 3a can be positioned lower than the outer peripheral surface of the shaft main body 2a, and the mascara liquid is discharged from the container main body. Since the base end of each bristle 3a does not come into contact with the handling port 6a of the handling member 6 formed in the container body when the tip end of the attached shaft portion 2 is pulled out, the load applied to the base end of the bristle 3a is reduced. Can do.

これにより容器本体から軸部２を引き抜く際に、扱き部材６によってブリッスル３ａが互い違いに根元から曲がるのを防ぐことができるので、ブリッスル３ａが散けて広がるのを防止することができる。   Thereby, when pulling out the shaft part 2 from the container main body, the bristle 3a can be prevented from being bent alternately from the root by the handling member 6, so that the bristle 3a can be prevented from spreading and spreading.

次にコーム部３に使用する材料を変えて上記のマスカラ塗布具１と従来のマスカラ塗布具１’とを比較した結果について説明する。   Next, the results of comparing the mascara applicator 1 and the conventional mascara applicator 1 'by changing the material used for the comb portion 3 will be described.

図７に材料としてＰＢＴ（ポリブチレンテレフタレート）、ナイロン等のＰＡ（ポリアミド系樹脂）、ポリエステル系熱可塑性エラストマーをそれぞれ使用して形成されたコーム部３を有するマスカラ塗布具１と、前記コーム部３を有し、図１２に示す如く、ブリッスル３ａ’の基端が軸本体２ａ’の外周面から起立してなる従来のマスカラ塗布具１’とを、それぞれ扱き部材６が形成された容器本体に１００回出し入れしたときのブリッスル３ａ、３ａ’の散けの結果を示す。   FIG. 7 shows a mascara applicator 1 having a comb portion 3 formed using PBT (polybutylene terephthalate), PA (polyamide resin) such as nylon, and a polyester thermoplastic elastomer as materials, and the comb portion 3. As shown in FIG. 12, a conventional mascara applicator 1 ′ in which the base end of a bristle 3a ′ is erected from the outer peripheral surface of the shaft main body 2a ′ is used as a container main body on which a handling member 6 is formed. The result of the scattering of the bristle 3a and 3a ′ when it is taken in and out 100 times is shown.

なお具体的な材料として、ＰＢＴは三菱エンジニアリングプラスチツクス株式会社製ノバデュラン（登録商標）５０１０ＴＲＸ５、ＰＡは旭化成化学株式会社製レオナ（登録商標）ナイロン６６繊維１３００Ｓ、東洋紡績株式会社製ペルプレン（登録商標）Ｐ−２８０Ｂを使用し、ブリッスル３ａ、３ａ’はそれぞれテーパーを有して形成されたものを使用した。また図７中のブリッスルは４５°斜めから５０倍率で撮影した。なお図７中、散けが多い順にバツ印、三角印、丸三角印、丸印で示した。   As specific materials, PBT is Novaduran (registered trademark) 5010TRX5 manufactured by Mitsubishi Engineering Plastics Co., Ltd., PA is Leona (registered trademark) nylon 66 fiber 1300S manufactured by Asahi Kasei Chemicals, and Perprene (registered trademark) manufactured by Toyobo Co., Ltd. P-280B was used, and the bristle 3a and 3a 'were each formed with a taper. In addition, the bristle in FIG. 7 was taken at a magnification of 50 ° from an angle of 45 °. In FIG. 7, the cross mark, triangle mark, round triangle mark, and circle mark indicate in order of increasing scattering.

図７の表に示す如く、軸部２にスリット２ｄを有さない従来のマスカラ塗布具１’のコーム部３では、ＰＢＴ、ＰＡ、ポリエステル系熱可塑性エラストマーのいずれの材料を使用した場合でもブリッスル３ａ’に散けが生じてしまった。 As shown in the table of FIG. 7, in the comb portion 3 of the conventional mascara applicator 1 ′ having no slit 2d in the shaft portion 2, no matter whether PBT, PA, or a polyester-based thermoplastic elastomer is used, the bristle is used. Scattering has occurred in 3a '.

それに対して本発明のスリット２ｄを有するマスカラ塗布具１のコーム部３では、ＰＢＴ又はＰＡの材料を使用した場合にはブリッスル３ａに散けが生じてしまったが、ポリエステル系熱可塑性エラストマーすなわち東洋紡績株式会社製ペルプレン（登録商標）Ｐ−２８０Ｂを使用した場合には散けは生じなかった。 On the other hand, in the comb portion 3 of the mascara applicator 1 having the slit 2d of the present invention, when the PBT or PA material is used, the bristle 3a is scattered, but the polyester-based thermoplastic elastomer, that is, Toyobo When Perprene (registered trademark) P-280B manufactured by Co., Ltd. was used, no scattering occurred.

上記によりコーム部３に使用する材料としては、ポリエステル系熱可塑性エラストマーを使用することが好ましい。   As a material used for the comb part 3 by the above, it is preferable to use a polyester-type thermoplastic elastomer.

またマスカラ塗布具１では、軸部２は比較的硬い材料で形成されることが好ましいが、コーム部３は、ブリッスル３ａに付着したマスカラ液を扱き落とすために、しなり易い材料で形成されることが好ましい。そこでペルプレン（登録商標）のグレードを変えた材料でコーム部３を形成し、上記と同様に容器本体に１００回出し入れを行って、材料毎に比較を行った。図８にこの比較結果を示す。なおグレードとしては硬度の低い順に、Ｐ−１５０Ｂ、Ｐ−２８０Ｂ、Ｅ−４５０Ｂを使用した。   Further, in the mascara applicator 1, the shaft portion 2 is preferably formed of a relatively hard material, but the comb portion 3 is formed of a material that is easily bent in order to handle the mascara liquid adhering to the bristle 3a. It is preferable. Then, the comb part 3 was formed with the material which changed the grade of the perprene (trademark), and it put in and out of the container main body 100 times similarly to the above, and compared for every material. FIG. 8 shows the comparison result. As grades, P-150B, P-280B, and E-450B were used in descending order of hardness.

図８の表に示す如く、従来のマスカラ塗布具１’のコーム部３では、いずれのグレードのペルプレン（登録商標）を使用した場合でも、ブリッスル３ａ’に散けが生じてしまった。また本発明のマスカラ塗布具１のコーム部３では、上記グレード中の低硬度であり、ＡＳＴＭ Ｄ２２４０試験方法によって測定された表面硬度が５７Ｄ、ＡＳＴＭ Ｄ７９０試験方法によって測定された曲げ弾性率が２８９ＭＰａであるＰ−１５０Ｂの材料を使用した場合のみブリッスル３ａに散けが生じてしまったが、中硬度であり、前記表面硬度が６８Ｄ、前記曲げ弾性率が４９４ＭＰａであるＰ−２８０Ｂの材料及び高硬度であり、前記表面硬度が７８Ｄ、前記曲げ弾性率が１２６７ＭＰａであるＥ−４５０Ｂの材料を使用した場合には散けが生じなかった。   As shown in the table of FIG. 8, in the comb portion 3 of the conventional mascara applicator 1 ′, the bristle 3 a ′ was scattered regardless of which grade of perprene (registered trademark) was used. In the comb part 3 of the mascara applicator 1 of the present invention, the hardness is low in the above grade, the surface hardness measured by the ASTM D2240 test method is 57D, and the flexural modulus measured by the ASTM D790 test method is 289 MPa. Only when a certain P-150B material was used, the bristle 3a was scattered, but it had a medium hardness, the surface hardness was 68D, and the bending elastic modulus was 494 MPa, and the P-280B material had a high hardness. Yes, no scattering occurred when the E-450B material having the surface hardness of 78D and the flexural modulus of 1267 MPa was used.

また図８の表に示す如く、Ｐ−１５０Ｂは、ブリッスル３ａ、３ａ’の腰が若干乏しいすなわちしなり易さが乏しく、さらに成形時に型を開くのが困難であったため、成形性やしなり易さの観点からＰ−２８０Ｂ及び／又はＰ−４５０Ｂの方が材料として好ましいと考える。   In addition, as shown in the table of FIG. 8, P-150B has bristle 3a and 3a 'that are slightly less elastic, that is, less flexible, and it is difficult to open the mold at the time of molding. From the viewpoint of easiness, P-280B and / or P-450B are considered preferable as a material.

上記によりコーム部３に使用する材料としては、前記表面硬度が６０Ｄ以上であることが好ましく、前記曲げ弾性率は４００ＭＰａ以上であることが好ましい。   As a material used for the comb part 3 as described above, the surface hardness is preferably 60D or more, and the flexural modulus is preferably 400 MPa or more.

なお本実施形態のマスカラ塗布具１のコーム部３は、ポリエステル系の熱可塑性エラストマーを使用して形成したが、本発明はこれに限られるものではなく、例えばポリアミド系の熱可塑性エラストマーを使用してもよい。具体的にはダイセル・テグサ株式会社製ダイアミドＰＡＥ（登録商標）又はアルケマ−東京材料株式会社製ベバックス（登録商標）等を使用することができる。   The comb portion 3 of the mascara applicator 1 of the present embodiment is formed using a polyester-based thermoplastic elastomer, but the present invention is not limited to this, and for example, a polyamide-based thermoplastic elastomer is used. May be. Specifically, Daicel PAX (registered trademark) manufactured by Daicel Tegusa Co., Ltd. or Bevacs (registered trademark) manufactured by Arkema-Tokyo Materials Co., Ltd. can be used.
