特開２００４−１５９８２３号公報参照 As shown in FIG. 6, the mascara brush integrally formed from a conventional synthetic resin has a coating portion 5 in which a plurality of brush hairs 14 b are implanted in the tip portion 10 of the handle 2. There are things (see Patent Document 1 below). In the mascara brush by integral molding, it is difficult to make the bristles 14b thinner from the limit of the flowability of the molding resin. Compared with the brush bristles in which synthetic fibers are implanted, the feeling of handling delicate wrinkles and the direct skin The touch when touched has the drawback of a strong bristle feel. Therefore, in this mascara brush, the cross-section of the brush hair 14a is made triangular so that the brush hair 14a can be easily passed between wrinkles and eyebrows and is soft for safety when touching the skin or the like.
See JP 2004-159823 A

ところで、前記特許文献１に開示した一体成形によるマスカラブラシに対しては、尚いっそう柔らかいブラシ毛１４ａが必要との要望も寄せられている。   By the way, the mascara brush by the integral molding disclosed in Patent Document 1 has been requested to have a softer bristle 14a.

そこで、本発明は、前記要望に鑑みてなされたもので、柄の先端部周囲に複数列からなる多数の細いブラシ毛を一体成形した化粧用塗布具において、価格を上昇させることなく、ブラシ毛をいっそう柔らかくすることを課題とする。   Therefore, the present invention has been made in view of the above-mentioned demand, and in a cosmetic applicator integrally formed with a plurality of thin brush hairs in a plurality of rows around the tip of the handle, the brush hairs without increasing the price. The challenge is to make the softer softer.

上記の課題を解決するため、請求項１に係る発明は、柄の先端部に複数列からなる多数のブラシ毛を柄の先端部と一体に成形した化粧用塗布具において、各ブラシ毛は、柄の先端部の周方向の一方側に後側面を向け、他方側に前記後側面以外の二側面を向けた略三角形断面をしており、前記後側面の延長面は柄の先端部の中心軸を含み、前記後側面以外の二側面には抜け勾配が設けられたことを特徴とする。   In order to solve the above-mentioned problem, the invention according to claim 1 is a cosmetic applicator in which a large number of brush bristles formed in a plurality of rows are formed integrally with the tip end portion of the handle. The front end of the handle has a substantially triangular cross-section with the rear side facing one side in the circumferential direction and the other side facing the two sides other than the rear side, and the extended surface of the rear side is the center of the tip of the handle Including the shaft, the two side surfaces other than the rear side surface are provided with a draft angle.

請求項２に係る発明は、請求項１に係る発明において、前記ブラシ毛の先端部には、前記後側面側ほど高くなる傾斜面が形成されたことを特徴とする。   The invention according to claim 2 is characterized in that, in the invention according to claim 1, an inclined surface that is higher toward the rear side surface is formed at the tip of the brush bristles.

請求項３に係る発明は、請求項１又は２に係る発明において、前記各列の前記ブラシ毛のピッチは、前記周方向の位置に応じて変化させたことを特徴とする。   The invention according to claim 3 is the invention according to claim 1 or 2, wherein the pitch of the bristles in each row is changed according to the position in the circumferential direction.

請求項４に係る発明は、前記請求項１、２又は３に記載の化粧用塗布具を形成する化粧用塗布具成形金型であって、該化粧用塗布具成形金型は、扇形をした金型単位を組み合わせて構成し、各金型単位においては二側面のうちの一方側にのみブラシ毛形成用のＶ字溝を形成したことを特徴とする。   The invention according to claim 4 is a cosmetic applicator molding die for forming the cosmetic applicator according to claim 1, 2, or 3, wherein the cosmetic applicator molding die has a fan shape. The mold unit is configured in combination, and each mold unit is characterized in that a V-shaped groove for forming a bristle is formed only on one side of two side surfaces.

請求項1に係る発明によれば、各ブラシ毛は、柄の先端部の周方向の一方側に後側面を向け、他方側に前記後側面以外の二側面を向けた略三角形断面をしており、前記後側面の延長面は柄の先端部の中心軸を含み、前記後側面以外の二側面には抜け勾配が設けられているが、これは、ブラシ毛の後側面は完全に柄の先端部の中心軸から放射状に延びており、前記後側面以外の二側面により形成される前記ブラシ毛の前縁は後側面側へ傾いていることを意味する。したがって、この化粧用塗布具によって、ブラシ毛の前縁を前方にして睫やまゆ毛をさばくと、ブラシ毛が、睫やまゆ毛の間を通り易くなるとともに、後方に変形し易く柔らかいものとなり、使い易い化粧用塗布具が得られる。また、ブラシ毛の後側面は完全に柄の先端部の中心軸から放射状であって、ブラシ毛の前縁が後方へ傾斜するのであるから、ブラシ毛の形成するためには扇形の金型単位を組み合わせた金型を使用するのであるが、この金型単位の一方の側面にのみにブラシ毛形成用のＶ字溝を設ければよい。これによって、金型を安価に製作できるので、価格を上昇させることなく安価に化粧用塗布具を製造できる。   According to the invention of claim 1, each bristle has a substantially triangular cross-section with the rear side facing one side in the circumferential direction of the tip of the handle and the other side facing the two side surfaces other than the rear side. The extension surface of the rear side includes the central axis of the tip of the handle, and the two side surfaces other than the rear side are provided with a draft angle. It means that the front edge of the bristle that extends radially from the central axis of the tip and is formed by two side surfaces other than the rear side surface is inclined toward the rear side surface. Therefore, when this cosmetic applicator is used to handle the eyelashes or eyebrows with the front edge of the brush hairs in front, the brush hairs can easily pass between the eyelashes and eyebrows and become soft and easily deformed backwards. An easy-to-use cosmetic applicator is obtained. In addition, the rear side of the brush bristle is completely radial from the central axis of the tip of the handle, and the front edge of the brush bristle is inclined backwards. However, it is only necessary to provide a V-shaped groove for forming the bristle on only one side surface of the mold unit. As a result, the mold can be manufactured at low cost, and the cosmetic applicator can be manufactured at low cost without increasing the price.

請求項２に係る発明によれば、さらにブラシ毛の先端部には前記後側面側ほど高くなる傾斜面が形成されているから、いっそうブラシ毛が睫やまゆ毛等の間を通り易くなって使い易い。   According to the second aspect of the present invention, the tip of the bristle is further provided with an inclined surface that becomes higher toward the rear side, so that the bristle is more easily passed between the eyelashes and eyebrows. easy.

請求項３に係る発明によれば、各列のブラシ毛のピッチは、前記周方向の位置に応じて変化させたから、睫やまゆ毛の状況に応じて適切なピッチのブラシ毛を使用できるので、いっそう使い易くなる。   According to the invention according to claim 3, since the pitch of the bristle in each row is changed according to the position in the circumferential direction, the bristle with an appropriate pitch can be used according to the situation of eyelashes and eyebrows, It becomes easier to use.

請求項４に係る発明によれば、化粧用塗布具成形金型は、扇形をした金型単位を組み合わせて構成し、各金型単位においては二側面のうちの一方側にのみブラシ毛形成用のＶ字溝を形成したから、この化粧用塗布具成形金型を安価に製作でき、これによって化粧用塗布具を安価に製造できる。   According to the fourth aspect of the present invention, the cosmetic applicator molding die is configured by combining fan-shaped mold units, and each mold unit is for forming brush hairs only on one side of two side surfaces. Since this V-shaped groove is formed, the cosmetic applicator molding die can be manufactured at low cost, and the cosmetic applicator can be manufactured at low cost.

以下、図１〜図５に基づいて、本発明の化粧用塗布具であるマスカラブラシとして、望ましい実施例について詳細に説明する。   Hereinafter, based on FIGS. 1-5, a preferable Example is demonstrated in detail as a mascara brush which is the cosmetic applicator of this invention.

図１は、このマスカラブラシの柄の先端部の正面図である。図２は、この前記マスカラブラシの柄の先端部の側面図である。図３は、ブラシ毛の拡大図である。図４は、マスカラブラシの製造に用いる金型の構造を説明する図である。図５は、前記金型を構成する金型単位の形状を説明する図である。   FIG. 1 is a front view of the tip of the mascara brush handle. FIG. 2 is a side view of the tip of the mascara brush handle. FIG. 3 is an enlarged view of the brush hair. FIG. 4 is a diagram illustrating the structure of a mold used for manufacturing a mascara brush. FIG. 5 is a diagram for explaining the shape of a mold unit constituting the mold.

マスカラブラシは、図１及び図２に示したように、柄２０の先端部２２が円筒状に形成されており、この先端部２２の周囲に放射状に１０列の先細のブラシ毛２４を形成したものであり、柄２０、この先端部２２及びブラシ毛２４がポリプロピレン（ＰＰ）等の合成樹脂で一体に形成されている。   In the mascara brush, as shown in FIGS. 1 and 2, the tip portion 22 of the handle 20 is formed in a cylindrical shape, and 10 rows of tapered brush hairs 24 are radially formed around the tip portion 22. The handle 20, the tip 22 and the brush bristles 24 are integrally formed of a synthetic resin such as polypropylene (PP).

図３に示したように、全てのブラシ毛１４は、図１の正面図で見て柄２０の先端部２２の周方向に対して、時計回りの方向に一側面２６（以下、この一側面２６を後側面と記載する。）を向け、反時計回りの方向に後側面２６以外の二側面２９を向けた略三角形断面を有している。ブラシ毛２４の後側面２６の延長面は、柄２０の先端部２２表面に垂直で、先端部２２の中心軸２８を含んでいる。ブラシ毛２４の後側面２６以外の二側面２９には、射出成形後に金型を取り除き易くするための抜け勾配が設けられる。したがって、図３に示したように、ブラシ毛２４は全体としても先細であるとともに、二側面２９の間の辺３０（以下、この辺３０を前縁と記載する。）は、先端側ほど後方へ傾斜することになる。   As shown in FIG. 3, all the bristles 14 have one side surface 26 (hereinafter referred to as one side surface) in a clockwise direction with respect to the circumferential direction of the tip portion 22 of the handle 20 as viewed in the front view of FIG. 26 is described as a rear side surface), and has a substantially triangular cross section in which two side surfaces 29 other than the rear side surface 26 are directed in a counterclockwise direction. An extension surface of the rear side surface 26 of the brush bristles 24 is perpendicular to the surface of the tip portion 22 of the handle 20 and includes a central axis 28 of the tip portion 22. The two side surfaces 29 other than the rear side surface 26 of the brush bristles 24 are provided with a draft angle for facilitating removal of the mold after injection molding. Therefore, as shown in FIG. 3, the brush bristles 24 are tapered as a whole, and a side 30 between the two side surfaces 29 (hereinafter, this side 30 is referred to as a front edge) is more backward toward the tip side. Will be inclined.

また、ブラシ毛２４の先端３２は、正面視及び後面視で丸く形成されるとともに、前縁３０側が低く後側面２６側が高くなるように傾斜している。   The tip 32 of the bristles 24 is formed round in front view and rear view, and is inclined so that the front edge 30 side is low and the rear side surface 26 side is high.

さらに、各列のブラシ毛２４は、柄２０の先端部２２の周方向位置に応じて、そのピッチが変えられている。例えば、図２において、上側の列のブラシ毛２４のピッチａは、下側の列のブラシ毛２４のピッチｂより大きくされる。両者の間の列のブラシ毛２４のピッチは、上半分はピッチａ、下半分はピッチｂとするか、または、両者のピッチａ、ｂの中間の値とする。   Furthermore, the pitch of the bristles 24 in each row is changed according to the circumferential position of the tip 22 of the handle 20. For example, in FIG. 2, the pitch a of the bristles 24 in the upper row is made larger than the pitch b of the bristles 24 in the lower row. As for the pitch of the bristles 24 in the row between them, the upper half is a pitch a and the lower half is a pitch b, or an intermediate value between the pitches a and b.

このように、ブラシ毛２４が三角形断面を有するとともに前縁３０が後側面２６側へ傾斜し、ブラシ毛２４の先端部３２も傾斜しているから、ブラシ毛２４の前縁３０が前方になるようにマスカラブラシを回転させながら睫やまゆ毛をさばくと、ブラシ毛２４が睫やまゆ毛の間を通り易くなるとともに後方に変形し易く柔らかいものとなって、使い易いマスカラブラシが得られる。また、各列のブラシ毛２４のピッチは、柄２０の先端部２２の周方向の位置に応じて変化させたから、睫やまゆ毛の状況に応じて適切なピッチのブラシ毛を使用できるので、いっそう使い易くなる。   Thus, since the bristle 24 has a triangular cross section, the front edge 30 is inclined toward the rear side surface 26, and the tip 32 of the brush bristle 24 is also inclined, so the front edge 30 of the brush bristle 24 is forward. When the eyelashes and eyebrows are separated while rotating the mascara brush as described above, the brush hairs 24 can easily pass between the eyelashes and eyebrows and are easily deformed backward, so that an easy-to-use mascara brush is obtained. Moreover, since the pitch of the bristle 24 of each row was changed according to the circumferential position of the tip portion 22 of the handle 20, it is possible to use the bristle with an appropriate pitch according to the situation of eyelashes and eyebrows. It becomes easy to use.

ブラシ毛２４の前縁３０及び先端部３２の傾斜方向は、右利き用に決定されている。これに対して、左利き用に前縁３０を図１とは逆方向へ傾斜させたものも造ってもよいが、コストアップの原因になるので、本発明のマスカラブラシは右利き専用としてもよい。   The inclination directions of the front edge 30 and the tip 32 of the brush bristles 24 are determined for right-handed use. On the other hand, a left-handed front edge 30 that is inclined in the direction opposite to that of FIG. 1 may be manufactured. However, since this causes a cost increase, the mascara brush of the present invention may be dedicated to right-handed use. .

このようなマスカラブラシの製造方法を説明する。マスカラブラシは、図４に示したように、射出成形するための金型３８は、全部で１０個の金型単位４２からなるが、一対の金型単位４２はボルト４４で結合されたブロック４０を構成している。したがって、各金型単位４２は、中心角が３６°の扇形の断面を有するとともに、その中心部が切り落とされていて、金型単位４２を全部組み合わせると、その中心部に柄２０及びその先端部２２を形成するための空所５０が形成される。   A method for manufacturing such a mascara brush will be described. In the mascara brush, as shown in FIG. 4, the mold 38 for injection molding is composed of ten mold units 42 in total, but the pair of mold units 42 is a block 40 joined by bolts 44. Is configured. Therefore, each mold unit 42 has a fan-shaped cross section with a central angle of 36 °, and its central part is cut off. When all the mold units 42 are combined, the handle 20 and its tip end part are in the central part. A void 50 for forming 22 is formed.

なお、金型単位４２の両端中心部４３は、円弧面に形成して、金型単位４２を組み合わせたとき、両端中心部４３の中心に円筒状の中心支持部５４を配置する。このような中心支持部５４を用いるのは、金型単位４２の両端中心部４３が尖ったままでは、高精度に製作し難いからである。柄２０の先端部２２に開けられた穴５５は、中心支持部５４の存在のために生じる。   In addition, the center part 43 of both ends of the mold unit 42 is formed in a circular arc surface, and when the mold unit 42 is combined, a cylindrical center support part 54 is disposed at the center of the center part 43 of both ends. The reason why such a center support portion 54 is used is that it is difficult to manufacture with high precision if both end center portions 43 of the mold unit 42 remain sharp. A hole 55 formed in the distal end portion 22 of the handle 20 is generated due to the presence of the center support portion 54.

金型単位４２の一方の面４６は完全な平面とされ、この平面４６がブラシ毛２４の後側面２６を形成する面となる。各金型単位４２の他方の面４８も平面とされ、空所５０に連通する断面Ｖ字形のＶ字溝５２が放電加工によって形成される。このＶ字溝５２は、ブラシ毛２４の前縁３０とこの両側の二面２９を形成するものであり、抜け勾配を形成するため、先端側ほど浅くされている。このＶ字溝５２の先端部５６も、ブラシ毛２４の後側面２６側が前縁３０側よりやや高くするように傾斜している。このような金型単位４２を組み合わせて金型を作り、射出成形によってマスカラブラシをつくると、図１に示したように、ブラシ毛２４の後側面２６の延長面は、柄２０の先端部２２の中心軸２８を含む位置となる。ブラシ毛２４の前縁３０の延長線は、柄２０の先端部２２の中心軸２８からずれた位置となるとともに、各ブラシ毛２４は前縁３０が後側面２６側に傾いたものとなる。   One surface 46 of the mold unit 42 is a complete flat surface, and this flat surface 46 is a surface that forms the rear side surface 26 of the brush bristles 24. The other surface 48 of each mold unit 42 is also a flat surface, and a V-shaped groove 52 having a V-shaped cross section communicating with the cavity 50 is formed by electric discharge machining. The V-shaped groove 52 forms the front edge 30 of the bristles 24 and the two surfaces 29 on both sides thereof. The V-shaped groove 52 is made shallower toward the tip end side in order to form a draft gradient. The front end portion 56 of the V-shaped groove 52 is also inclined so that the rear side surface 26 side of the bristles 24 is slightly higher than the front edge 30 side. When a mold is made by combining such mold units 42 and a mascara brush is made by injection molding, the extended surface of the rear side 26 of the brush bristles 24 is the tip 22 of the handle 20 as shown in FIG. The center axis 28 is included. The extension line of the front edge 30 of the brush hair 24 is located at a position shifted from the central axis 28 of the distal end portion 22 of the handle 20, and each brush hair 24 has the front edge 30 inclined toward the rear side face 26.

このように、本実施例の金型を構成する金型単位４２においては、両側面４６、４８にブラシ毛４を形成するためのＶ字溝５２を設けずに、片側の側面４８だけにブラシ毛２４を形成するためのＶ字溝５２を設けたから、金型を造る労力が大幅に減って、コスト低減ができる。   As described above, in the mold unit 42 constituting the mold of the present embodiment, the V-shaped groove 52 for forming the brush hair 4 is not provided on the both side surfaces 46 and 48, and the brush is formed only on the one side surface 48. Since the V-shaped groove 52 for forming the hair 24 is provided, the labor for manufacturing the mold is greatly reduced, and the cost can be reduced.

ところで、本発明は、前記実施例に限るものではなく、例えば、次のように種々の変形が可能である。前記実施例ではブラシ毛２４を１０列設けたが、ブラシ毛２４の列数は適宜増減させてもよい。ブラシ毛２４の断面形状は、前記実施例では前縁３０に適度な丸みを持たせた略三角形としたが、前縁３０が尖った完全な三角形としてもよい。ブラシ毛２４の先端部３２の形状は、前記実施例では適度な丸みを持たせた曲面としたが、完全な平坦面としてもよい。各列のブラシ毛２４のピッチは、一定にする必要はなく、各列内の位置に応じて適宜変化させてもよい。各列のブラシ毛２４の長さは、一定にする必要はなく、各列の周方向位置又は各列内の位置に応じて適宜変化させてもよい。   By the way, the present invention is not limited to the above-described embodiment, and for example, various modifications are possible as follows. In the above embodiment, 10 rows of brush hairs 24 are provided, but the number of rows of brush hairs 24 may be increased or decreased as appropriate. The cross-sectional shape of the brush bristles 24 is a substantially triangular shape in which the front edge 30 is appropriately rounded in the above embodiment, but may be a complete triangle with a sharp front edge 30. The shape of the tip 32 of the brush bristles 24 is a curved surface with an appropriate roundness in the above embodiment, but may be a completely flat surface. The pitch of the brush bristles 24 in each row need not be constant, and may be changed as appropriate according to the position in each row. The length of the brush bristles 24 in each row does not need to be constant, and may be appropriately changed according to the circumferential position of each row or the position in each row.
