Description

本発明は、液状化粧料を塗布するための液状化粧料容器に関する。 The present invention relates to a liquid cosmetic container for applying a liquid cosmetic.

従来、例えば筆記具用のインクや液状化粧料等の液体を塗布する液体塗布具として、以下の特許文献１に記載のものが知られている。この特許文献１のものは、所謂直液式のものであり、容器内に直接充填された液体を中継芯を介して先端側の塗布体へ運び、このとき、中継芯を囲繞する液体保溜部材によって液量が最適に調節され、この液量が最適に調節された液体が塗布体から塗布できるようになっている。塗布体は、筒状のホルダーの先端側の固定部に挿通固定されており、液体保溜部材は、軸線方向に延びるコイル状の筒状体の外周面を植毛部材で覆ったもので、当該コイル状の筒状体内に、上記筒状のホルダーの後端側の長尺な小径部が挿嵌される構成となっている。 BACKGROUND ART Heretofore, as a liquid applicator for applying a liquid such as ink for a writing instrument or a liquid cosmetic, the one described in Patent Document 1 below has been known.

ここで、上記塗布体としては種々のものが採用され得るが、最近にあっては、塗布の際の肌触り等の触感を向上すべく、従来のものより柔らかい塗布体として、例えば細い繊維を接着剤で固めた繊維の集束体の採用が検討されている。 Here, as the above-mentioned application body, various ones can be adopted, but recently, in order to improve the tactile sensation such as touch when applying, as the application body softer than the conventional one, for example, thin fibers are bonded. Adoption of a bundle of fibers hardened with an agent is being considered.

しかしながら、このような柔らかい塗布体を筒状のホルダーに例えば圧入により装着しようとすると、塗布体が曲がってしまい、うまく圧入できないという問題がある。また、圧入により塗布体の気孔率が低下してしまう結果、液体を塗布体から良好に塗布できなかったり、圧入により塗布体の柔らかさが装着前より低下し硬くなってしまう虞がある。一方、緩嵌合により塗布体を装着した場合には、塗布体の掃除の際に、塗布体が引っ張られて抜け出てしまう虞がある。 However, if such a soft applicator is to be attached to a cylindrical holder by, for example, press fitting, there is a problem that the applicator is bent and cannot be press-fitted well. Further, as a result of the press-fitting, the porosity of the applicator decreases, so that the liquid may not be applied satisfactorily from the applicator, or the press-fitting may cause the softness of the applicator to decrease and become harder than before mounting. On the other hand, when the applicator body is mounted by loose fitting, the applicator body may be pulled out during cleaning of the applicator body.

そこで、本発明は、塗布体の柔らかさが保たれ、且つ、塗布体の装着が容易であり、且つ、液状化粧料を塗布体から良好に塗布でき、且つ、塗布体の掃除の際に当該塗布体が抜け出ることがない液状化粧料容器を提供することを目的とする。 Therefore, the present invention, the softness of the applicator is maintained, and the applicator can be easily attached, and liquid cosmetics can be favorably applied from the applicator, and at the time of cleaning the applicator. An object of the present invention is to provide a liquid cosmetic container in which an applied body does not come out.

本発明による液状化粧料容器は、液状化粧料を収容する収容部が内部に設けられた容器本体と、容器本体の先端側に設けられた筒状部材と、筒状部材の先端側に支持された塗布体と、収容部に収容された液状化粧料を塗布体に運ぶための中継芯と、を備えた液状化粧料容器において、筒状部材は、塗布体が挿入され塗布体を支持するホルダ部と、ホルダ部に続いて一体に構成され、中継芯が挿入されると共に当該中継芯周りに液量調節用のジャバラが設けられた吸蔵部と、を備え、ホルダ部の塗布体が挿入される筒孔の径は、吸蔵部の中継芯が挿入される筒孔の径より大きくされ、ホルダ部の周壁には、当該周壁を貫通する開口が設けられると共に、開口を形成する先端側の内面の辺縁には、内方へ突出する突起部が設けられ、塗布体には、その外周面に環状の溝部が設けられ、塗布体が筒状部材のホルダ部に挿入された状態で、ホルダ部の突起部が塗布体の溝部に進入し当該塗布体が軸線方向に係止され、突起部は、軸線方向の後端側から先端側に向かって、凹むように湾曲しながら内方への突出の度合いが徐々に小さくなっていることを特徴としている。 The liquid cosmetic container according to the present invention includes a container main body having an accommodating portion for accommodating the liquid cosmetic provided therein, a tubular member provided on the distal end side of the container main body, and a tubular member supported on the distal end side of the tubular member. In a liquid cosmetic container comprising a coating body and a relay core for carrying the liquid cosmetic stored in the housing portion to the coating body, the tubular member is a holder for supporting the coating body by inserting the coating body therein. And an occlusion part which is integrally formed following the holder part and in which the relay core is inserted and a bellows for liquid amount adjustment is provided around the relay core, and the application body of the holder part is inserted. The diameter of the cylindrical hole is larger than the diameter of the cylindrical hole into which the relay core of the occlusion part is inserted, and the peripheral wall of the holder part is provided with an opening penetrating the peripheral wall and the inner surface on the tip side forming the opening. A protrusion projecting inward is provided on the edge of the holder, an annular groove is provided on the outer peripheral surface of the applicator, and the applicator is inserted into the holder of the tubular member. The projection of the part enters the groove of the application body and the application body is locked in the axial direction, and the projection is curved inwardly from the rear end side in the axial direction toward the tip side and inward. The feature is that the degree of protrusion is gradually reduced .

このような液状化粧料容器によれば、塗布体は、筒状部材の先端側を構成するホルダ部に挿入され、ホルダ部の内面に設けられた突起部が、塗布体の外周面の環状の溝部に進入し、当該塗布体が軸線方向に係止される構成であり、ホルダ部に圧入される構成を採っていないため、塗布体の柔らかさが保たれ、且つ、塗布体のホルダ部に対する装着が容易であり、且つ、塗布体の気孔率が低下せず液状化粧料を塗布体から良好に塗布でき、且つ、塗布体の掃除の際に当該塗布体が抜け出ることはない。また、ホルダ部と、中継芯周りを構成する液量調節用のジャバラが設けられた吸蔵部とが、一体に構成されるため、従来の２部品が１部品とされ、部品点数を低減できる。 According to such a liquid cosmetic container, the applicator body is inserted into the holder part that constitutes the distal end side of the tubular member, and the protrusion provided on the inner surface of the holder part has an annular shape on the outer peripheral surface of the applicator body. Since the coating body enters the groove and is locked in the axial direction and is not press-fitted into the holder portion, the softness of the coating body is maintained and the coating body with respect to the holder portion is maintained. It is easy to put on, the liquid cosmetic can be well applied from the applicator without lowering the porosity of the applicator, and the applicator does not come out when the applicator is cleaned. Further, since the holder part and the occlusion part that is provided around the relay core and is provided with the bellows for adjusting the liquid amount are integrally formed, the conventional two parts are made into one part, and the number of parts can be reduced.

ここで、上記筒状部材を樹脂を用いて射出成形する場合には、筒状部材の内周面に対応する形状の外周面を備えたコアピン（内型）と、筒状部材の外周面に対応する形状の内面を備え上下に分離可能な外型との間に、溶融樹脂を射出し、固化後、ホルダ部を成形するためのホルダ部用コアピンを先端側の外方へ引き抜き離型すると共に、外型を分離し離型して筒状部材を得ることになるが、ホルダ部用コアピンにより、ホルダ部の突起部を成形しようとすると、当該ホルダ部用コアピンを先端側の外方へ引き抜く際に無理抜きとなり、不良品となる虞がある。 Here, when the tubular member is injection-molded using a resin, a core pin (inner die) having an outer peripheral surface having a shape corresponding to the inner peripheral surface of the tubular member and an outer peripheral surface of the tubular member are provided. Molten resin is injected between an outer mold that has an inner surface of a corresponding shape and can be separated into upper and lower parts, and after solidification, the core pin for the holder part for molding the holder part is pulled out toward the tip side and released. At the same time, the outer mold is separated and released to obtain a cylindrical member. However, when the holder core pin is used to form the protrusion of the holder, the holder core pin is moved outward on the tip side. When pulling out, there is a risk that the product will be forcibly pulled out, resulting in a defective product.

ここで、前述したように、筒状部材のホルダ部の周壁において突起部より後端側の位置に、当該周壁を貫通する開口が設けられているため、外型の内面に、上記開口に対応する形状の凸部を設けると共に、ホルダ部用コアピンにおいてホルダ部の突起部で上記開口の先端側の辺縁位置に対応する部分の外径Ｒ１を、これより後端側で外型の凸部が当接することになる部分の外径Ｒ２と同径とし、さらに、ホルダ部用コアピンにおいてホルダ部の突起部に対応する部分を先端側に向かって拡径する（Ｒ１，Ｒ２より大きい径とし内方への突出度合いを小さくする）構成とすることで、ホルダ部用コアピンを先端側に向かって順次大径とすることが可能となっており、ホルダ部用コアピンを無理抜きすること無くホルダ部の突起部の成形が可能となっている。従って、筒状部材を簡易に製造できるようになっている。なお、ホルダ部用コアピンをさらに引き抜きやすくすべく、ホルダ部用コアピンを、引き抜き側となる手前側より奥側に向かってテーパー状に縮径する構成としても良く、この場合には、Ｒ１＞Ｒ２となる。 Here, as described above, since the opening penetrating the peripheral wall of the holder portion of the tubular member at the rear end side of the protrusion portion is provided, the inner surface of the outer die corresponds to the opening. And the outer diameter R1 of the portion of the holder core pin corresponding to the edge position on the tip side of the opening in the holder core pin, and the outer protrusion on the rear end side. Has the same outer diameter as the outer diameter R2 of the portion to be in contact with, and further expands the portion of the holder core pin that corresponds to the protruding portion of the holder toward the tip side (a diameter larger than R1 and R2 (The degree of protrusion to one side is made smaller), the core pins for the holder part can be gradually increased in diameter toward the tip side, and the core pin for the holder part cannot be forcibly pulled out. It is possible to mold the protruding part of. Therefore, the tubular member can be easily manufactured. In order to make it easier to pull out the holder portion core pin, the holder portion core pin may be tapered from the front side, which is the pulling side, toward the back side, and in this case, R1>R2. Becomes

ここで、突起部は、軸線方向の後端側から先端側に向かって、凹むように湾曲しながら内方への突出の度合いが徐々に小さくなる構成のため、塗布体をその後端側から筒状部材のホルダ部へ挿入する際に、塗布体において溝部より拡径する後側の部分が、突起部を後端側へ向かって乗り越えやすく、塗布体のホルダ部に対する装着が一層容易である。また、本発明による液状化粧料容器は、突起部は、その後端となる辺縁の位置の突出部分が最も内方へ突出し、突出部分から先端側に向かって、凹むように湾曲しながら内方への突出の度合いが徐々に小さくなっていることを特徴としている。 Here, since the protrusion has a configuration in which the degree of inward projection gradually decreases from the rear end side in the axial direction toward the front end side while curving so as to be concave, When the applicator is inserted into the holder part, the rear part of the applicator body, which has a larger diameter than the groove part, easily gets over the projection part toward the rear end side, so that the applicator body can be more easily attached to the holder part. Further, in the liquid cosmetic container according to the present invention, the protruding portion is such that the protruding portion at the position of the rear edge is the innermost protruding portion, and the protruding portion is curved inward so as to be recessed toward the tip side. It is characterized in that the degree of protrusion to is gradually reduced.

このように本発明によれば、塗布体の柔らかさが保たれ、且つ、塗布体の装着が容易であり、且つ、液状化粧料を塗布体から良好に塗布でき、且つ、塗布体の掃除の際に当該塗布体が抜け出ることがなく、且つ、部品点数を低減でき、しかも、製造の際にコアピンの無理抜きがない構造で簡易に製造できる液状化粧料容器を提供できる。 As described above, according to the present invention, the softness of the applicator is maintained, the applicator is easily attached, and the liquid cosmetic can be applied well from the applicator, and the cleaning of the applicator can be performed. In this case, it is possible to provide a liquid cosmetic container in which the applied body does not come off at the time, the number of parts can be reduced, and the core pin is not forcibly removed during manufacturing.

把持筒１は、例えばＡＢＳ等から形成され、有底円筒状に構成される。この把持筒１は、使用者が把持して塗布しやすいように軸線方向に長尺を成している。 The grip cylinder 1 is made of, for example, ABS and has a bottomed cylindrical shape. The grip cylinder 1 is elongated in the axial direction so that the user can easily grip and apply the grip.

容器本体２は、例えばＰＰ等から形成され、略円筒状に構成される。図２に示すように、容器本体２は、その先端側の外周面に、円環状の鍔部２ｂを備え、鍔部２ｂより先端側は、外周面が先細となるテーパー面２ｔを有する構成とされる。図１に示すように、容器本体２の後端の開口は、例えばＰＰ等から成る尾栓４を容器本体２に装着することにより閉じられ、容器本体２内の筒状部材７より後側に形成された内部空間が、アイライナー化粧料Ｌが充填された収容部２ａとされる。収容部２ａ内には、アイライナー化粧料Ｌと共に、当該アイライナー化粧料Ｌを撹拌すべく例えばＳＵＳ等より形成された球状の撹拌子５が収容される。 The container body 2 is made of, for example, PP and has a substantially cylindrical shape. As shown in FIG. 2, the container main body 2 is provided with an annular flange portion 2b on the outer peripheral surface on the tip end side thereof, and has a tapered surface 2t having a tapered outer peripheral surface on the tip end side from the flange portion 2b. To be done. As shown in FIG. 1, the opening at the rear end of the container body 2 is closed by attaching a tail plug 4 made of, for example, PP to the container body 2, so that the container body 2 is located behind the tubular member 7. The formed internal space serves as a housing portion 2a filled with the eyeliner cosmetic material L. A spherical stirrer 5 made of, for example, SUS or the like for stirring the eyeliner cosmetic material L is housed in the housing portion 2a together with the eyeliner cosmetic material L.

そして、容器本体２は、その後端側から把持筒１の先端の筒孔に内挿され、その鍔部２ｂが、把持筒１の先端面に突き当たった状態で、把持筒１に着脱可能又は着脱不能に装着される。 Then, the container body 2 is inserted from the rear end side thereof into a cylindrical hole at the tip of the gripping cylinder 1, and the collar portion 2b thereof is attachable to and detachable from the gripping cylinder 1 in a state of abutting against the tip end surface of the gripping cylinder 1. It is installed impossible.

筒状部材７は、例えばＰＰ等から形成された一体成形品であり、図３〜図７に示すように、略円筒状に構成される。この筒状部材７は、先端側のホルダ部７ａと、ホルダ部７ａに連設され後端まで延びる吸蔵部７ｂ、とを備える。 The tubular member 7 is an integrally molded product formed of, for example, PP or the like, and has a substantially cylindrical shape as shown in FIGS. 3 to 7. The tubular member 7 includes a holder portion 7a on the front end side and an occlusion portion 7b that is connected to the holder portion 7a and extends to the rear end.

ホルダ部７ａは、塗布体３を支持するためのものであり、塗布体３が挿入される筒孔７ｉを軸心位置に有する。ホルダ部７ａの周壁には、当該周壁を内外に貫通する開口７ｈが一対対向して設けられる。図６及び図７に示すように、ホルダ部７ａの開口７ｈを形成する先端側の内面の辺縁辺りには、内方へ突出する突起部７ｄが設けられる。突起部７ｄは、その後端となる辺縁の位置の突出部分７ｋが最も内方へ突出しており、当該突出部分７ｋから先端側へ向けて（図６の右側から左側へ向けて）凹むように湾曲しながら、内方への突出の度合いが徐々に小さくなっている。 The holder portion 7a is for supporting the application body 3, and has a cylindrical hole 7i into which the application body 3 is inserted at an axial center position. A pair of openings 7h are formed on the peripheral wall of the holder portion 7a so as to penetrate the peripheral wall inward and outward. As shown in FIGS. 6 and 7, an inwardly projecting protrusion 7d is provided around the edge of the inner surface of the holder portion 7a on the tip side that forms the opening 7h. The projecting portion 7d has the projecting portion 7k at the peripheral edge position, which is the rear end thereof, that projects most inward, and is recessed from the projecting portion 7k toward the tip side (from the right side to the left side in FIG. 6). While curving, the degree of inward projection gradually decreases.

なお、突起部７ｄは、ここでは、特に好ましいとして、後端側から先端側へ向けて湾曲しながら、内方への突出の度合いが徐々に小さくなる形状とされているが、湾曲ではなく、テーパー面であっても良く、階段状の段差面であっても良い。 It should be noted that, here, as the protrusion 7d, it is particularly preferable that the protrusion 7d has a shape in which the degree of inward projection gradually decreases while curving from the rear end side toward the front end side. It may be a tapered surface or a stepped step surface.

また、ここでは、特に好ましいとして、開口７ｈ及び突起部７ｄの組を一対（２組）設けているが、１組や３組以上であっても良い。 Further, here, it is particularly preferable to provide a pair (two sets) of the opening 7h and the protrusion 7d, but one set or three or more sets may be provided.

吸蔵部７ｂは、図２に示すように、中継芯６を保持すると共に、当該中継芯６を通して塗布体３へ供給されるアイライナー化粧料Ｌの液量を調節するためのものである。図３〜図６に示すように、吸蔵部７ｂは、その先端部７ｍがホルダ部７ａより多少大きくされ、その先端面が、塗布体３の後端面を突き当てるための面とされる。図６に示すように、先端部７ｍ及び当該先端部７ｍより後側の部分の軸心位置には、中継芯６が挿入される筒孔７ｇが設けられる。筒孔７ｇは、ホルダ部７ａの筒孔７ｉに連設され、筒孔７ｇの径は、ホルダ部７ａの筒孔７ｉの径より小さくされている。 As shown in FIG. 2, the occlusion part 7b is for holding the relay core 6 and adjusting the liquid amount of the eyeliner cosmetic L supplied to the application body 3 through the relay core 6. As shown in FIGS. 3 to 6, the occluding portion 7b has a tip portion 7m slightly larger than the holder portion 7a, and the tip surface is a surface for abutting the rear end surface of the applicator body 3. As shown in FIG. 6, a cylindrical hole 7g into which the relay core 6 is inserted is provided at the axial center position of the tip portion 7m and the portion behind the tip portion 7m. The cylindrical hole 7g is connected to the cylindrical hole 7i of the holder portion 7a, and the diameter of the cylindrical hole 7g is smaller than the diameter of the cylindrical hole 7i of the holder portion 7a.

筒孔７ｇは、前半部の筒孔７ｅと、当該筒孔７ｅに連設される後半部の筒孔７ｆとに分けられ、前半部の筒孔７ｅより後半部の筒孔７ｆの方が大きくされている。後半部の筒孔７ｆは、中継芯６を遊嵌案内するためのものであり、前半部の筒孔７ｅは、中継芯６を嵌合固定するためのものである。 The cylindrical hole 7g is divided into a cylindrical hole 7e in the front half and a cylindrical hole 7f in the latter half that is connected to the cylindrical hole 7e, and the cylindrical hole 7f in the latter half is larger than the cylindrical hole 7e in the front half. Has been done. The cylindrical hole 7f in the latter half is for loosely guiding the relay core 6, and the cylindrical hole 7e in the front half is for fitting and fixing the relay core 6.

図３〜図６に示すように、吸蔵部７ｂの先端部７ｍより後側の部分には、所謂ジャバラ７ｎが設けられる。ジャバラ７ｎは、極薄板を軸線方向に沿って極小間隔で多数枚並設して成るものであり、筒孔７ｇを囲繞すると共に、極薄板同士間のジャバラ空間が筒孔７ｇに連通する構成となっている。そして、ジャバラ７ｎは、気圧に応じてジャバラ空間にアイライナー化粧料Ｌを保持し又は放出することにより、筒孔７ｇを流れ塗布体３へ向かうアイライナー化粧料Ｌの流量を最適に調節する。 As shown in FIGS. 3 to 6, a so-called bellows 7n is provided in a portion of the occluding portion 7b on the rear side of the front end portion 7m. The bellows 7n is formed by arranging a large number of ultra-thin plates in parallel along the axial direction at a minimum interval, and surrounds the cylindrical hole 7g, and a bellows space between the ultra-thin plates communicates with the cylindrical hole 7g. Is becoming Then, the bellows 7n holds or releases the eyeliner cosmetic L in the bellows space according to the atmospheric pressure to optimally adjust the flow rate of the eyeliner cosmetic L flowing through the cylindrical hole 7g toward the application body 3.

塗布体３は、ここでは、例えばＰＡ（ポリアミド）より成る細い繊維を接着剤で固めた繊維の集束体とされ、図２及び図８に示すように、先端が尖鋭でブラシのような外観を呈するチップである。 Here, the applicator body 3 is a bundle of fibers made of fine fibers made of, for example, PA (polyamide), which are hardened with an adhesive, and has a sharp tip and a brush-like appearance, as shown in FIGS. 2 and 8. It is a tip to present.

塗布体３は、その後半側の外周面に、ホルダ部７ａの突起部７ｄが進入するための円環状の溝部３ｄを備える。 The applicator 3 is provided with an annular groove 3d on the outer peripheral surface on the latter half side thereof, into which the projection 7d of the holder 7a enters.

そして、塗布体３は、その後端側から筒状部材７のホルダ部７ａに緩い嵌合で内挿され、その後端面が吸蔵部７ｂの先端部７ｍの先端面に突き当てられた状態で支持されると共に、その溝部３ｄに、ホルダ部７ａの突起部７ｄが進入し、軸線方向に係止された状態となっている。 Then, the applicator body 3 is inserted from the rear end side thereof into the holder portion 7a of the tubular member 7 by loose fitting, and is supported in a state where the rear end face thereof is abutted against the front end face of the front end portion 7m of the occlusion portion 7b. At the same time, the projection 7d of the holder 7a enters the groove 3d and is locked in the axial direction.

ここで、前述したように、ホルダ部７ａの突起部７ｄは、後端側から先端側に向かって、内方への突出の度合いが徐々に小さくなっているため（図６参照）、塗布体３を、その後端側から筒状部材７のホルダ部７ａへ挿入する際に、塗布体３の溝部３ｄより後側の部分３ｂ（図２及び図８参照）が、突起部７ｄを後端側へ向かって乗り越えやすく、塗布体３のホルダ部７ａに対する装着が容易となっている。 Here, as described above, the protrusion 7d of the holder portion 7a has a gradually decreasing degree of inward projection from the rear end side toward the front end side (see FIG. 6). 3 is inserted into the holder portion 7a of the tubular member 7 from the rear end side thereof, the portion 3b (see FIGS. 2 and 8) on the rear side of the groove portion 3d of the application body 3 moves the protruding portion 7d on the rear end side. It is easy to get over and the application body 3 can be easily attached to the holder portion 7a.

また、上記塗布体３は、その繊維径が、０．５デニール以上、且つ、５デニール以下とされると共に、その気孔率が、５０％以上、且つ、８０％以下とされている。 Further, the fiber diameter of the coated body 3 is 0.5 denier or more and 5 denier or less, and the porosity thereof is 50% or more and 80% or less.

繊維径の最小値が０．５デニールとされているのは、現時点で加工できる最小径だからである。繊維径の最大値が５デニールとされているのは、５デニールを超えると、使用上において柔らかさが保てなくなり肌触りが悪くなるからである。 The minimum fiber diameter is set to 0.5 denier because it is the minimum diameter that can be processed at the present time. The maximum value of the fiber diameter is set to 5 denier because if it exceeds 5 denier, the softness cannot be maintained during use and the touch becomes poor.

また、気孔率の最小値が５０％とされているのは、５０％より小さくなると、アイライナー化粧料Ｌが当該塗布体３を通り難くなり出が悪くなると共に、使用上において柔らかさが保てなくなり肌触りが悪くなるからである。気孔率の最大値が８０％とされているのは、現時点で加工でき柔らかくできる最大値だからである。 The minimum porosity of 50% means that when the porosity is less than 50%, it is difficult for the eyeliner cosmetic L to pass through the applicator body 3 and it is difficult to get it out. This is because the texture will disappear and the texture will become worse. The maximum value of the porosity is 80% because it is the maximum value that can be processed and softened at the present time.

そして、塗布体３は、前述したように、ホルダ部７ａに緩い嵌合で挿入されているため、上記気孔率５０％以上が維持されている。このような気孔率５０％以上が確保されていれば、塗布体３は、ホルダ部７ａ内において軸線周りに回転可能でも回転不能でも良い。 The applicator body 3 is inserted into the holder portion 7a with a loose fit as described above, so that the porosity of 50% or more is maintained. If such a porosity of 50% or more is ensured, the applicator body 3 may or may not be rotatable around the axis in the holder portion 7a.

中継芯６は、例えばアクリル樹脂等から形成され、軸線方向に延在する軸体状を呈している。この中継芯６は、毛細管現象を発現するものであり、その先端面には尖鋭部６ａが設けられている。 The relay core 6 is made of, for example, acrylic resin or the like, and has a shaft-like shape extending in the axial direction. The relay core 6 exhibits a capillary phenomenon, and a sharpened portion 6a is provided on the tip end surface thereof.

そして、中継芯６は、その先端側から吸蔵部７ｂの筒孔７ｇの後半部の筒孔７ｆに内挿され、当該筒孔７ｆに遊嵌案内されながら、中継芯６の前半部が、筒孔７ｇの前半部の筒孔７ｅに進入し嵌合固定される。従って、この中継芯６周りに上記ジャバラ７ｎが設けられた状態となっている。また、中継芯６の先端の尖鋭部６ａは、塗布体３の後端面に突き刺さるように進入し当接した状態にある。 Then, the relay core 6 is inserted from the front end side thereof into the cylinder hole 7f in the latter half of the cylinder hole 7g of the occlusion portion 7b, and the front half of the relay core 6 is guided while being loosely fitted and guided in the cylinder hole 7f. The cylindrical hole 7e in the front half of the hole 7g is fitted and fixed. Therefore, the bellows 7n is provided around the relay core 6. Further, the sharpened portion 6a at the tip of the relay core 6 is in a state of entering and abutting the rear end surface of the applicator body 3 so as to pierce it.

このように、塗布体３及び中継芯６を装着した筒状部材７は、その先端側から容器本体２の後端の筒孔に内挿され、その円筒状の後端部７ｃが、容器本体２の内周面の凹部２ｃに嵌合することにより、容器本体２に装着される。この状態で、筒状部材７の先端部の外周面が、容器本体２の先端部内の凸部２ｄに径方向にガイドされて固定される。また、この状態で、上記中継芯６は、その後端側の部分が収容部２ａ内に進入し、従って、中継芯６は収容部２ａ内と塗布体３とを繋ぎ、収容部２ａ内のアイライナー化粧料Ｌを塗布体３へ供給することが可能となっている。 In this way, the tubular member 7 with the applicator 3 and the relay core 6 attached thereto is inserted into the tubular hole at the rear end of the container body 2 from its tip side, and the cylindrical rear end portion 7c is By fitting in the concave portion 2c on the inner peripheral surface of 2, the container body 2 is mounted. In this state, the outer peripheral surface of the tip portion of the tubular member 7 is radially guided and fixed to the convex portion 2d in the tip portion of the container body 2. Further, in this state, the rear end portion of the relay core 6 enters the accommodation portion 2a, so that the relay core 6 connects the accommodation portion 2a and the coating body 3 to each other and the eye in the accommodation portion 2a. It is possible to supply the liner cosmetic L to the applicator body 3.

再び図１に戻って、キャップ１０は、塗布体３を保護するためのものであり、有底円筒状を呈し、嵌合により容器本体２の先端部に着脱自在に装着される。キャップ１０内には、さらに内キャップ１１が設けられる。内キャップ１１は、コイルバネ１２により容器本体２側に付勢され、キャップ１０の後端面が容器本体２の鍔部２ｂの先端面に突き当てられ、キャップ１０が容器本体２に装着されると、内キャップ１１が容器本体２の先端側のテーパー面２ｔに密着して気密を確保し、アイライナー化粧料Ｌの揮散が防止される。 Returning to FIG. 1 again, the cap 10 is for protecting the application body 3, has a bottomed cylindrical shape, and is detachably attached to the tip of the container body 2 by fitting. An inner cap 11 is further provided inside the cap 10. The inner cap 11 is urged toward the container body 2 by the coil spring 12, the rear end surface of the cap 10 is abutted against the tip surface of the flange portion 2b of the container body 2, and the cap 10 is attached to the container body 2. The inner cap 11 is in close contact with the tapered surface 2t on the tip side of the container body 2 to ensure airtightness, and volatilization of the eyeliner cosmetic material L is prevented.

このようなアイライナー化粧料容器１００によれば、塗布体３は、筒状部材７のホルダ部７ａに挿入され、ホルダ部７ａの内面に設けられた突起部７ｄが、塗布体３の環状の溝部３ｄに進入し、当該塗布体３が軸線方向に係止される構成であり、ホルダ部７ａに圧入される構成を採っていないため、塗布体３の柔らかさが保たれ、且つ、塗布体３のホルダ部７ａに対する装着が容易であり、且つ、塗布体３の気孔率が低下せずアイライナー化粧料Ｌを塗布体３から良好に塗布でき、且つ、塗布体３の掃除の際に当該塗布体３が抜け出ることはない。また、ホルダ部７ａと、液量調節用のジャバラ７ｎが設けられた吸蔵部７ｂとが、一体に構成されるため、従来の２部品が１部品とされ、部品点数を低減できる。 According to such an eyeliner cosmetic container 100, the applicator body 3 is inserted into the holder portion 7a of the tubular member 7, and the protrusion 7d provided on the inner surface of the holder portion 7a has an annular shape. Since the coating body 3 enters the groove portion 3d and is locked in the axial direction and is not press-fitted into the holder portion 7a, the softness of the coating body 3 is maintained and the coating body 3 is maintained. 3 is easily attached to the holder portion 7a, the porosity of the applicator body 3 does not decrease, and the eyeliner cosmetic L can be satisfactorily applied from the applicator body 3 while cleaning the applicator body 3. The coated body 3 does not come out. Further, since the holder portion 7a and the occlusion portion 7b provided with the liquid amount adjusting bellows 7n are integrally formed, the conventional two parts are made into one part, and the number of parts can be reduced.

次に、このようなアイライナー化粧料容器１００を構成する筒状部材７を製造する射出成形及びこれに用いる成形型（金型）について説明する。 Next, the injection molding for manufacturing the tubular member 7 constituting the eyeliner cosmetic container 100 and the molding die (mold) used for the injection molding will be described.

図９及び図１０は、筒状部材を製造する際に用いられる成形型の分解斜視図、図１１は、図９及び図１０に示す成形型を用いた成形時の様子を示す水平断面図、図１２は、垂直断面図である。 9 and 10 are exploded perspective views of a molding die used in manufacturing a tubular member, and FIG. 11 is a horizontal sectional view showing a state at the time of molding using the molding die shown in FIGS. 9 and 10. FIG. 12 is a vertical sectional view.

先ず、成形型として、図９〜図１２に示すように、筒状部材７の外面（図４及び図５参照）に対応する凹形状５０ｃを内面に有する外型としての上型５０ａ（図１２参照）及び下型５０ｂと、筒状部材７のホルダ部７ａの筒孔７ｉ（図６及び図７参照）に対応する外面を有する内型としてのホルダ部用コアピン５１ａと、筒状部材７の吸蔵部７ｂの筒孔７ｇ（図６参照）に対応する外面を有する内型としての吸蔵部用コアピン５１ｂを用意する。 First, as a molding die, as shown in FIGS. 9 to 12, an upper die 50a (FIG. 12) as an outer die having a concave shape 50c corresponding to the outer surface (see FIGS. 4 and 5) of the tubular member 7 on the inner surface (FIG. 12). Lower mold 50b, a holder part core pin 51a as an inner mold having an outer surface corresponding to the cylindrical hole 7i (see FIGS. 6 and 7) of the holder part 7a of the cylindrical member 7, and the cylindrical member 7 of the cylindrical member 7. A core pin 51b for an occlusion part is prepared as an inner mold having an outer surface corresponding to the cylindrical hole 7g (see FIG. 6) of the occlusion part 7b.

上型５０ａ及び下型５０ｂの凹形状５０ｃの先端側（成形品となる筒状部材７と同様に図示左側）には、筒状部材７のホルダ部７ａの一対の開口７ｈに対応する凸部５０ｄがそれぞれ設けられる。また、上型５０ａの凹形状５０ｃの後半部には、ジャバラ７ｎの上半分に対応する凹凸部５０ｅが軸線方向に並設されると共に、下型５０ｂの凹形状５０ｃの後半部には、ジャバラ７ｎの下半分に対応する凹凸部５０ｆが軸線方向に並設される。これら上型５０ａの凹凸部５０ｅと下型５０ｂの凹凸部５０ｆとでは、図１２に示すように、多少形状が異なっているが、凸部５０ｄ等の他の形状は同一である。 On the tip side of the concave shapes 50c of the upper mold 50a and the lower mold 50b (on the left side in the drawing like the cylindrical member 7 that is a molded product), the convex portions corresponding to the pair of openings 7h of the holder portion 7a of the cylindrical member 7 are formed. 50d are provided respectively. Further, in the latter half of the concave shape 50c of the upper die 50a, an uneven portion 50e corresponding to the upper half of the bellows 7n is arranged in parallel in the axial direction, and in the latter half of the concave shape 50c of the lower die 50b, the bellows are formed. Concavo-convex portions 50f corresponding to the lower half of 7n are arranged side by side in the axial direction. The unevenness 50e of the upper mold 50a and the unevenness 50f of the lower mold 50b are slightly different in shape as shown in FIG. 12, but the other shapes such as the convex 50d are the same.

ホルダ部用コアピン５１ａの後端側には、上型５０ａ及び下型５０ｂの凸部５０ｄが進入して当接する凹部５１ｃがそれぞれ設けられる。この凹部５１ｃは、その後端が後方へ開放される。凹部５１ｃの前端縁には、前方へ向かって凹むように湾曲しながらへこみの深さが浅くなっていく凹部５１ｄがそれぞれ設けられる。この凹部５１ｄが突起部７ｄに対応する部分となる。 On the rear end side of the holder portion core pin 51a, there are provided recesses 51c into which the protrusions 50d of the upper die 50a and the lower die 50b enter and contact. The rear end of the recess 51c is opened rearward. The front end edge of the recessed portion 51c is provided with a recessed portion 51d that is curved so as to be recessed toward the front and has a shallower indentation. This recess 51d becomes a portion corresponding to the protrusion 7d.

ホルダ部用コアピン５１ａは、さらに詳説すると、図１２に示すように、ホルダ部７ａの突起部７ｄのうちの突出部分７ｋ（図６参照）に対応する部分（凹部５１ｃの先端縁）の外径Ｒ１と、これより後端側で外型５０ａ，５０ｂの凸部５０ｄが当接することになる部分の外径Ｒ２（凹部５１ｃの底面同士の間の長さ）とが同径となっており、凹部５１ｃの先端縁に連設された凹部５１ｄは、先端側に向かって外径Ｒ１が、徐々に拡径する構成となっている。 The holder portion core pin 51a will be described in further detail. As shown in FIG. 12, the outer diameter of the portion (the tip edge of the recess 51c) corresponding to the protruding portion 7k (see FIG. 6) of the protruding portion 7d of the holder portion 7a. R1 and the outer diameter R2 (the length between the bottoms of the recesses 51c) of the portion where the protrusions 50d of the outer molds 50a and 50b come into contact with each other on the rear end side have the same diameter, The recess 51d, which is continuously provided on the tip edge of the recess 51c, has a configuration in which the outer diameter R1 gradually increases toward the tip side.

また、吸蔵部用コアピン５１ｂは、前半部の外面が、筒状部材７の吸蔵部７ｂの前側の筒孔７ｅに対応する小径とされ、後半部の外面が、筒状部材７の吸蔵部７ｂの後側の筒孔７ｆに対応する大径とされている。 The outer surface of the front half of the occlusion part core pin 51b has a small diameter corresponding to the front cylindrical hole 7e of the occlusion part 7b of the tubular member 7, and the outer surface of the latter half of the occlusion part 7b of the tubular member 7 is small. It has a large diameter corresponding to the rear cylindrical hole 7f.

そして、このような構成のホルダ部用コアピン５１ａと、吸蔵部用コアピン５１ｂを、図１１及び図１２に示すように、上型５０ａの凹形状５０ｃと下型５０ｂの凹形状５０ｃとの間に所定に位置するようにセットする。このとき、上型５０ａ及び下型５０ｂの凸部５０ｄが、ホルダ部用コアピン５１ａの外周面（凹部５１ｃの底面）に当接する。次いで、上型５０ａ及び下型５０ｂと、ホルダ部用コアピン５１ａ及び吸蔵部用コアピン５１ｂとの間に形成された隙間に、溶融樹脂５２を射出し、この溶融樹脂５２が固化することで、上型５０ａ及び下型５０ｂと、ホルダ部用コアピン５１ａ及び吸蔵部用コアピン５１ｂとの間に、筒状部材７を成形する。 Then, as shown in FIGS. 11 and 12, the core pin 51a for the holder part and the core pin 51b for the occlusion part having such a structure are provided between the concave shape 50c of the upper mold 50a and the concave shape 50c of the lower mold 50b. Set so that it is in the specified position. At this time, the protrusions 50d of the upper mold 50a and the lower mold 50b contact the outer peripheral surface of the holder core pin 51a (the bottom surface of the recess 51c). Next, the molten resin 52 is injected into the gap formed between the upper die 50a and the lower die 50b, and the holder portion core pin 51a and the occlusion portion core pin 51b, and the molten resin 52 is solidified. The tubular member 7 is molded between the mold 50a and the lower mold 50b and the holder portion core pin 51a and the storage portion core pin 51b.

次いで、離型を行う。このとき、ホルダ部用コアピン５１ａは先端側の外方へ、吸蔵部用コアピン５１ｂは後端側の外方へ各々引き抜かれ、各々が大径側から引き抜かれるため（途中に引き抜きの引っ掛かりとなる凸部がないため）、無理抜きとはならず円滑に引き抜かれ、図３〜図７に示す筒状部材７が得られる。 Next, release is performed. At this time, the core pin 51a for the holder part is pulled out to the outside on the tip side, and the core pin 51b for the storage part is pulled out to the outside on the rear end side, and each of them is pulled out from the large diameter side (it becomes a catch of pulling in the middle. Since there is no convex portion), the tubular member 7 is smoothly pulled out without being forcedly pulled out, and the tubular member 7 shown in FIGS. 3 to 7 is obtained.

このように、本実施形態によれば、筒状部材７のホルダ部７ａの周壁において突起部７ｄより後端側の位置に、当該周壁を貫通する開口７ｈが設けられているため、外型５０ａ，５０ｂの内面に、上記開口７ｈに対応する形状の凸部５０ｄを設けると共に、ホルダ部用コアピン５１ａにおいてホルダ部７ａの突起部７ｄで上記開口７ｈの先端側の辺縁位置に対応する部分の外径Ｒ１を、これより後端側で外型５０ａ，５０ｂの凸部５０ｄが当接することになる部分の外径Ｒ２と同径とし、さらに、ホルダ部用コアピン５１ａにおいてホルダ部７ａの突起部７ｄに対応する部分を先端側に向かって拡径する（Ｒ１，Ｒ２より大きい径とし内方への突出度合いを小さくする）構成とすることで、ホルダ部用コアピン５１ａが先端側に向かって順次大径となっており、ホルダ部用コアピン５１ａを無理抜きすること無くホルダ部７ａの突起部７ｄを成形できるようになっている。従って、筒状部材７を簡易に製造できるようになっている。因みに、ホルダ部用コアピン５１ａをさらに引き抜きやすくすべく、ホルダ部用コアピン５１ａを、引き抜き側となる手前側（図示左側）より奥側（図示右側）に向かってテーパー状に縮径する構成としても良い。この場合には、Ｒ１＞Ｒ２となる。 As described above, according to the present embodiment, since the opening 7h penetrating the peripheral wall of the holder portion 7a of the tubular member 7 is provided at the position on the rear end side of the protruding portion 7d, the outer die 50a. , 50b is provided with a convex portion 50d having a shape corresponding to the opening 7h, and the core pin 51a for the holder portion has a protrusion 7d of the holder portion 7a, which is a portion corresponding to the edge position on the tip side of the opening 7h. The outer diameter R1 is set to be the same as the outer diameter R2 of the portion on the rear end side of which the protrusions 50d of the outer molds 50a and 50b come into contact, and the protrusion of the holder portion 7a in the holder portion core pin 51a. By configuring the portion corresponding to 7d to be expanded toward the tip side (the diameter is made larger than R1 and R2 to reduce the degree of inward projection), the core pin 51a for the holder part is sequentially directed toward the tip side. The diameter is large, and the protrusion 7d of the holder portion 7a can be molded without forcibly removing the holder portion core pin 51a. Therefore, the tubular member 7 can be easily manufactured. Incidentally, in order to make it easier to pull out the holder part core pin 51a, the holder part core pin 51a may be tapered toward the inner side (right side in the drawing) from the front side (left side in the drawing) to be pulled out. good. In this case, R1>R2.

なお、ここでは、吸蔵部７ｂの筒孔７ｇの後半部の筒孔７ｆを大きくし、当該吸蔵部７ｂの後端から中継芯６を挿入しやすくする一方で、吸蔵部７ｂの筒孔７ｇの前半部の筒孔７ｅを小径とし、当該筒孔７ｅで中継芯６の前半部を嵌合固定するようにしているが、吸蔵部７ｂの筒孔７ｇは、先端から後端に亘って同径であっても良い。この場合には、吸蔵部用コアピン５１ｂを、当該吸蔵部用コアピン５１ｂより大径のホルダ部用コアピン５１ａと一体化し、成形時にあって、ホルダ部用コアピン５１ａと共に先端側の外方へ引き抜き離型するようにしても良い。 In addition, here, the cylindrical hole 7f in the latter half of the cylindrical hole 7g of the occlusion portion 7b is enlarged to facilitate insertion of the relay core 6 from the rear end of the occlusion portion 7b, while the cylindrical hole 7g of the occlusion portion 7b is formed. The diameter of the cylinder hole 7e in the front half is small and the front half of the relay core 6 is fitted and fixed in the cylinder hole 7e. However, the cylinder hole 7g of the occlusion part 7b has the same diameter from the front end to the rear end. May be In this case, the core pin 51b for the occlusion part is integrated with the core pin 51a for the holder part having a larger diameter than the core pin 51b for the occlusion part, and at the time of molding, the core pin 51b for the holder part is pulled outward together with the core pin 51a for the holder part. It may be shaped.
