JP 2000-262324 A

この液状化粧料押出容器にあっては、容器の落下等による衝撃や振動等により、また、温度変化による液状化粧料の粘度変化等によって、液状化粧料が容器先端から漏出し、手や衣類等を汚す虞がある。 In this liquid cosmetic extrusion container, liquid cosmetic material leaks from the tip of the container due to impact or vibration due to dropping of the container, etc., or due to changes in viscosity of the liquid cosmetic due to temperature changes, etc. There is a risk of soiling.

また、この液状化粧料押出容器にあっては、液状化粧料の塗布時に液状化粧料が出過ぎてしまい、良好に塗布することが難い場合がある。 Moreover, in this liquid cosmetics extrusion container, liquid cosmetics may come out too much at the time of application of liquid cosmetics, and it may be difficult to apply | coat well.

本発明は、このような課題を解決するために成されたものであり、液状化粧料を始めとした液状充填物の漏出に起因する汚れの発生が防止されると共に液状充填物が良好に塗布される塗布具を提供することを目的とする。 The present invention has been made to solve such problems, and prevents the occurrence of dirt due to leakage of liquid fillers such as liquid cosmetics, and allows the liquid fillers to be applied satisfactorily. An object is to provide an applicator.

本発明による塗布具は、内部の充填領域に充填された液状充填物を先端側に向かって押し出し可能に構成された容器本体のその先端部に対して装着され、充填領域に連通し軸線に沿って先端側に延び、且つ、その軸線方向先端が閉じられた孔部を備えるコア部材と、コア部材の先端側を覆うように回り止めを介して軸線周りに回転不能且つ軸線方向に移動不能に装着された塗布部材と、を具備し、コア部材の先端側と塗布部材との間には内部空間が画成され、塗布部材は、その先端面に開口された吐出口と内部空間を連通させる吐出孔を備え、コア部材は、その周面に開口され孔部と内部空間とを連通させる連通孔を備え、回り止めは、コア部材の外周の先端から後方へ軸線方向に延び、且つ、周方向に沿って複数形成された溝部と、塗布部材の内周に形成されコア部材の溝部に嵌り込む突条と、を有するものであり、溝部は、連通孔に係る前側部分と、回り止めに係る後側部分と、を有するものであり、この連通孔に係る前側部分の内側の面と孔部の外周面とが重合することにより連通孔が開口されていることを特徴としている。
The applicator according to the present invention is attached to the tip of the container body configured to be able to extrude the liquid filling filled in the filling region inside toward the tip, and communicates with the filling region along the axis. A core member that has a hole that extends to the distal end side and that has a closed end in the axial direction, and is non-rotatable around the axial line and non-movable in the axial direction so as to cover the distal end side of the core member. An inner space is defined between the distal end side of the core member and the coating member, and the coating member communicates the discharge port opened at the distal end surface with the inner space. The core member is provided with a communication hole that is opened in the peripheral surface thereof and communicates the hole portion and the internal space, and the rotation stopper extends in the axial direction from the front end of the outer periphery of the core member to the rear. A plurality of grooves formed along the direction, and a coating portion And a protrusion that fits into the groove of the core member, and the groove has a front part related to the communication hole and a rear part related to rotation prevention. The communication hole is opened by superposition of the inner surface of the front portion of the communication hole and the outer peripheral surface of the hole.

このような塗布具によれば、液状充填物の流路が、コア部材に設けられ充填領域に連通し先端側に延びると共に軸線方向先端が閉じられた孔部、この孔部に連通し半径方向外側に向かい且つコア部材の先端側の外周に設けられコア部材の先端から後方側へ所定に延びる溝部のその内側の面を開口する連通孔、コア部材の先端側と塗布部材との間に画成される内部空間を介して、塗布部材の吐出孔に向かう流路とされる。このため、液状充填物は、一挙に吐出孔へ向かうことは無く流れに抵抗が与えられるが如く回り込むようにして吐出孔へ向かう。従って、容器の落下等による衝撃や振動を始めとして温度変化による液状充填物の粘度変化等が作用しても、液状充填物の漏出が防止されると共に、塗布時にあっては液状充填物の出過ぎが防止されて吐出量が適量とされる。また、溝部の内側の面と孔部の外周面とが重合することで連通孔が溝部に開口される構成のため、コア部材の外形に対応する外型と、コア部材の孔部に対応する中型とを用いてコア部材を成形する場合に、外型の溝部の連通孔に対応する部分を中型に接触する外型形状とすることで、連通孔に対応する中型が無くても連通孔を容易に形成できる。
According to such an applicator, the flow path of the liquid filling is provided in the core member, communicates with the filling region, extends to the distal end side, and closes the axial distal end, and communicates with the hole in the radial direction. A communication hole that is provided on the outer periphery of the core member and that extends outward from the tip of the core member and extends in a predetermined direction from the tip of the core member to the rear side. The communication hole opens between the tip of the core member and the coating member. The flow path is directed to the discharge hole of the application member through the formed internal space. For this reason, the liquid filling does not go to the discharge hole at once, but flows toward the discharge hole so as to flow around as though resistance is given to the flow. Therefore, leakage of the liquid filling is prevented even if impact or vibration due to dropping of the container or the like causes a change in the viscosity of the liquid filling due to temperature change, etc. Is prevented, and the discharge amount is set to an appropriate amount. In addition, since the communication hole is opened in the groove by overlapping the inner surface of the groove and the outer peripheral surface of the hole, the outer mold corresponding to the outer shape of the core member and the hole of the core member When forming the core member using the middle mold, the portion corresponding to the communication hole of the groove portion of the outer mold is formed into an outer mold shape that contacts the middle mold, so that the communication hole can be formed even if there is no middle mold corresponding to the communication hole. Can be easily formed.

このように本発明による塗布具によれば、手や衣類等に対する液状充填物の漏出による汚れの発生を未然に防止することが可能になると共に、液状充填物を良好に塗布することが可能となる。 As described above, according to the applicator according to the present invention, it is possible to prevent the occurrence of dirt due to leakage of the liquid filler to the hand or clothing, and to satisfactorily apply the liquid filler.

When the cleaning liquid is pushed out from the filling region 10a according to the user's operation, the flow path of the cleaning liquid is directed to the discharge hole 3f of the coating member 3 through the hole 2a, the communication hole 2j, and the internal space 4 of the core member 2. Since the cleaning liquid does not go to the discharge hole 3f at once, resistance is given to the flow as shown by the arrow in the figure, and the cleaning liquid goes to the discharge hole 3f as shown by the arrows. Since the outer surface of the protruding portion 2f is close to the discharge hole 3f, the discharge hole 3f is narrowed.

このため、塗布時の洗浄液の出過ぎが防止されて吐出量が適量とされ、洗浄液は良好に塗布される。 For this reason, excessive discharge of the cleaning liquid at the time of application is prevented, the discharge amount is set to an appropriate amount, and the cleaning liquid is applied satisfactorily.

この時、塗布部材３の吐出口３ｇの周囲には、ブラシ機能を有する多数の突起群３ｂがあるため、これらの突起群３ｂ及び洗浄液により、皮膚、特に毛穴の汚れが効果的に除去される。しかも、突起群３ｂは、塗布部材３の軸線方向に対して傾斜する方向に突出している（傾斜する先端面３ａに対して垂設されている）ため、汚れが一層効果的に除去される。 At this time, since there are a large number of protrusion groups 3b having a brush function around the discharge port 3g of the application member 3, the protrusions 3b and the cleaning liquid effectively remove dirt on the skin, particularly pores. . Moreover, since the protrusion group 3b protrudes in a direction inclined with respect to the axial direction of the application member 3 (is suspended from the inclined front end surface 3a), dirt is more effectively removed.

また、この時、塗布部材３の突条３ｅ及びコア部材２の溝部２ｈにより、当該塗布部材３の回り止めが構成されているため、塗布の際に塗布部材３は回ることがなく、洗浄液は一層良好に塗布される。 At this time, since the protrusion 3e of the application member 3 and the groove 2h of the core member 2 constitute a rotation stop of the application member 3, the application member 3 does not rotate during application, and the cleaning liquid It is applied better.

また、このような塗布具１を備える液状化粧料押出容器２０に対して、落下等による衝撃や振動が作用したり、温度変化による洗浄液の粘度変化等が作用しても、前述のように、吐出孔３ｆが絞られていると共に洗浄液の流路が大きく回り込む流路とされているため、洗浄液の漏出が防止され、手や衣類等を汚すことが未然に防止されている。 Moreover, even if impact or vibration due to dropping or the like acts on the liquid cosmetic extrusion container 20 provided with such an applicator 1, or changes in the viscosity of the cleaning liquid due to temperature changes, as described above, Since the discharge hole 3f is narrowed and the flow path of the cleaning liquid is a large flow path, leakage of the cleaning liquid is prevented, and the hands and clothes are prevented from being soiled.

なお、コア部材２の突出部２ｆの外面と吐出孔３ｆとの間の隙間は、例えば洗浄液の粘度等により調整される。 In addition, the clearance gap between the outer surface of the protrusion part 2f of the core member 2 and the discharge hole 3f is adjusted with the viscosity etc. of a washing | cleaning liquid, for example.

なお、上記実施形態においては、洗浄液の漏出を防止するのに特に有効であるとして、コア部材２の突出部２ｆが塗布部材３の吐出孔３ｆに進入するようにしているが、突出部２ｆは吐出孔３ｆに進入していなくても良い。 In the above embodiment, the protrusion 2f of the core member 2 enters the discharge hole 3f of the coating member 3 as being particularly effective for preventing leakage of the cleaning liquid, but the protrusion 2f It does not have to enter the discharge hole 3f.

また、上記実施形態においては、特に製造が容易であると共に洗浄液の流れの制御が容易であるとして、塗布部材３の吐出孔３ｆの形状を円形（この時の吐出口３ｇの形状を楕円形）とし、コア部材２の突出部２ｆの形状を円錐状に各々しているが、例えば、吐出孔３ｆの形状を楕円形（この時の吐出口３ｇの形状を円形）や、その他矩形等にしても良く、また、突出部２ｆの形状を例えば角錐状等にしても良い。 Further, in the above embodiment, the shape of the discharge hole 3f of the coating member 3 is circular (the shape of the discharge port 3g at this time is elliptical) because it is particularly easy to manufacture and the flow of the cleaning liquid is easy to control. The shape of the projecting portion 2f of the core member 2 is conical, but for example, the shape of the discharge hole 3f is elliptical (the shape of the discharge port 3g at this time is circular), other rectangles, etc. In addition, the shape of the protrusion 2f may be a pyramid shape, for example.

また、上記実施形態においては、塗布部材３をコア部材２に装着するようにしているが、例えば本体筒１０等に直接装着することも可能である。 Moreover, in the said embodiment, although the application member 3 is mounted | worn with the core member 2, it is also possible to mount | wear directly with the main body cylinder 10 grade | etc., For example.

因みに、上記実施形態においては、特に好適であるとして、液状充填物を洗浄液としているが、洗浄液に限定されるものではなく、美容液、ネールケア溶液、ネールリムーバー、マスカラ、アンチエイジング、ヘアーカラー、頭髪用化粧料、オーラルケア、マッサージオイル、角栓ゆるめ液、マーキングペン等の筆記用具等のインク、液状の医薬品、泥状物、靴墨等の液状充填物としても良い。 Incidentally, in the above embodiment, the liquid filling is used as a cleaning liquid as being particularly suitable, but the liquid filling is not limited to the cleaning liquid, but is a cosmetic liquid, nail care solution, nail remover, mascara, anti-aging, hair color, hair. Cosmetics for oral use, oral care, massage oil, square plug loosening liquid, ink for writing instruments such as marking pens, and liquid fillings such as liquid pharmaceuticals, mud, shoes.

Further, a projection group 33b around the discharge ports 33g and 33g includes It has a long comb shape.

また、図１２に示す塗布具４１にあっては、塗布部材４３の先端面４３ａに、吐出口を覆う大径のスポンジ状の塗布体４３ｃが装着されると共に、この塗布体４３ｃの周囲に、疣状の突起群４３ｂが環状に配設されている。 Further, in the applicator 41 shown in FIG. 12, a large-diameter sponge-like applicator 43c that covers the discharge port is attached to the distal end surface 43a of the applicator member 43, and around the applicator 43c, A hook-shaped projection group 43b is annularly arranged.

また、図１３に示す塗布具５１にあっては、塗布部材５３の先端面５３ａが細幅となるように当該塗布部材５３が先端側に行くに従い絞られ、細幅の先端面５３ａの長手方向に、長尺のくし状とされる突起群５３ｂが並列されると共に、この突起群５３ｂが吐出口の周囲に位置するように設けられている。この突起群５３ｂは、塗布部材５３の軸線方向に対して傾斜する方向に突出するように設けられている。 Further, in the applicator 51 shown in FIG. 13, the application member 53 is squeezed toward the tip side so that the tip surface 53a of the application member 53 becomes narrow, and the longitudinal direction of the narrow tip surface 53a. In addition, a long comb-shaped projection group 53b is arranged in parallel, and the projection group 53b is provided around the discharge port. The protrusion group 53 b is provided so as to protrude in a direction inclined with respect to the axial direction of the application member 53.

そして、このような図１１〜図１３に示す構成の塗布具３１，４１，５１を、上記種々の液状充填物に応じて適宜選択することで、最適な使用に供することが可能である。因みに、突起群が、図１３に示すように、塗布部材の軸線方向に対して傾斜する方向に突出していると、突起群の機能の多様化が図れるという利点がある。 And it is possible to use for the optimal use by selecting suitably the applicator 31,41,51 of the structure shown in FIGS. 11-13 according to the said various liquid fillers. Incidentally, if the protrusion group protrudes in a direction inclined with respect to the axial direction of the application member as shown in FIG. 13, there is an advantage that the functions of the protrusion group can be diversified.
