Brush holding structure of liquid cosmetic applicator
To make it easier to draw a thin line with a sharp tapered brush member, a brush-holding structure of a liquid cosmetic applicator has a tubular applicator body in which a cotton pad or liquid cosmetic is contained, and a nosepiece having a permeable brush-hold member securely inserted therein and fitted in a tip portion of the applicator body, wherein a through hole is formed in a center position of the brush-hold member and extending in a lengthwise direction, a brush member formed of a bundle of filamentous fibers is securely inserted and fitted in the through hole, and a tip portion of the brush member protrudes from a tip of the brush-hold member.
1. Field of the Invention
The present invention relates to a brush-holding structure of a liquid cosmetic applicator for applying a liquid cosmetic such as an eyeliner liquid.
2. Prior Art
There is a liquid cosmetic applicator having a structure as shown in
A base portion 5b of the brush tip 5 is provided with a relaying pad 9 inserted therein. The relaying pad 9 is inserted in a tip portion 3a of the cotton pad 3. The intervention of the relaying pad 9 between the brush tip 5 and the cotton pad 3 allows a liquid cosmetic impregnated in the cotton pad 3 to flow to the brush tip 5.
That is, the liquid cosmetic applicator 1 is used to discharge the liquid cosmetic impregnated in the cotton pad 3 from the brush tip 5. Because the conventional liquid cosmetic applicator 1 has the relaying pad 9 provided in the center position of the brush tip 5, however, it is necessary to pull off the longest hair (so-called life hair) positioned in the center portion of the brush tip 5. As a result, the brush tip 5 cannot be formed into a sharp and fine shape.
SUMMARY OF THE INVENTIONAccordingly, it is an object of the present invention to provide a liquid cosmetic applicator that overcomes the problem of the conventional liquid cosmetic applicator and has a brush member tapered to have a sharp shape to make it easier to draw a thin line.
According to the present invention, there is provided a brush-holding structure of a liquid cosmetic applicator having at least a tubular applicator body in which a cotton pad or liquid cosmetic is contained, and a nosepiece having a permeable brush-hold member securely inserted therein and fitted in a tip portion of the applicator body, the brush-holding structure having a through hole formed in a center position of the brush-hold member and extending in a lengthwise direction, and a brush member formed by a bundle of filamentous fibers and securely inserted in the through hole, wherein a tip portion of the brush member protrudes from a tip of the brush-hold member.
It is preferable that the brush-hold member should closely contact an entire outer surface of the brush member excluding the tip portion thereof, and have a cross-sectional area larger than that of the brush member. The through hole can have a circular or elliptical cross section. The through hole preferably has an inside diameter of 0.8 to 3.5 mm.
The brush-holding structure of a liquid cosmetic applicator according to the present invention is configured so that a through hole extending in the lengthwise direction is formed in the center position of a pervious brush-hold member securely inserted in a nosepiece, a brush member is securely inserted in the through hole, and the tip portion of the brush member protrudes from the tip of the brush-hold member. This can make the brush member formed into a tapered sharp shape, so that a thin line can be drawn.
As the brush-hold member closely contacts the entire outer surface of the brush member excluding the tip portion thereof, and has a cross-sectional area larger than that of the brush member, thus ensuring the smooth use of the liquid cosmetic applicator without interrupting the supply of the liquid cosmetic to the tip portion of the brush member. Further, the circular or elliptical cross section of the through hole can permit the shape of the brush member to be formed to fit a portion where the liquid cosmetic is to be applied.
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. For easier understanding, same reference numerals are given to those components of the embodiments that are similar or same as the corresponding components of the related art.
The applicator body 2 is formed into a tubular shape with both the tip portion 2a and the rear end portion 2b being open. A step portion 14 is formed at the outer surface of the applicator body 2 on the tip portion 2a side along the circumferential direction, and an opened end portion 6b of the cap 6 abuts on the step portion 14. A diameter-educed portion 15 is provided at the step portion 14, extending therefrom. The diameter-reduced portion 15 has an inside diameter corresponding to the outside diameter of the nosepiece 12.
The cotton pad 3 is formed into an approximately cylindrical shape and is retained in the applicator body 2. A liquid cosmetic, such as an eyeliner liquid, is impregnated in the cotton pad 3. As shown in
The applicator body 2 may be configured to directly contain a liquid cosmetic, not the cotton pad 3, therein.
As shown in
A brush-hold member 13 is inserted and held in the nosepiece 12. The brush-hold member 13 is formed of polyester fibers or nylon fibers or the like hardened by polyurethane foam, and is superior in permeability of liquid cosmetics. As shown in
As shown in
As the brush-hold member 13 closely contacts the entire outer surface of the brush member 20 excluding the tip portion 20a thereof, and has a cross-sectional area larger than that of the brush member 20. That is, the ability of the brush-hold member 13 to suck and feed a liquid cosmetic is set larger than that of the brush member 20, so that the amount of the liquid cosmetic to be supplied is larger than the amount of the liquid cosmetic consumed by the brush member 20. Accordingly, the liquid cosmetic can be supplemented to the tip portion 20a of the brush member 20 to be applied without interruption.
The diameter of the through hole 21 of the brush-hold member 13 is preferably about 0.8 to 3.5 mm. The through hole 21 may have an elliptical cross section as well as a circular cross section. The cross-sectional shape of the brush member 20 is formed to be circular or elliptical in accordance with the cross-sectional shape of the through hole 21. That is, the brush member 20 is formed to have an optimal shape for a portion to which the liquid cosmetic is to be applied.
Because the cap 6 and the tail stopper 7 have structures similar to those of the prior art, their descriptions will be given referring to
A projection 22 is formed circumferentially on the outer surface of a tubular portion 18 of a nosepiece 12 used in the brush-holding structure. The outside diameter of the projection 22 is set slightly larger than the inside diameter of a diameter-educed portion 15 of an applicator body 2, so that as the tubular portion 18 of the nosepiece 12 is press-fitted into the diameter-reduced portion 15 of the applicator body 2, the nosepiece 12 is more surely held inside the tip portion 2a of the applicator body 2 in a tight state. A brush-hold member 23 is formed slightly thicker than the brush-hold member 13 of the first embodiment, and a through hole 21 extending in the lengthwise direction is formed in a center position of the brush-hold member 23. The brush-hold member 23 is formed into an elliptical shape as shown in
Since, unlike the prior art, the liquid cosmetic applicator 11 with the foregoing structure does not need a relaying pad, it is not necessary to pull off the longest hair positioned in the center portion of the brush-hold member. That is, the brush-hold member 13, 23 can be formed into a sharp and fine shape, so that a thin line can be drawn well. In addition, the brush-holding structure of a liquid cosmetic applicator can ensure the use thereof without interrupting the supply of a liquid cosmetic to the tip portion 20a of the brush member 20.
