[Problem to be solved by the invention]

However, the conventional mascara applicator has a brush shape in order to easily apply the mascara liquid from the middle position to the tip side of the eyelashes. Therefore, it does not fully correspond to any growth process of adult hair, lanugo, etc. of the eyelashes which exist on an eyelid. Also, although human eyelashes grow from the mucous membrane of the eyelids, it is difficult and time-consuming to apply mascara when the eyelashes grow out. In particular, it is labor-intensive to apply the mascara liquid from the short eyelashes in the upper and lower eyelids near the end of the nose, and from the roots in the mucous membrane of the eyelashes.

Herein, an object of the present invention is to provide a mascara applicator that can easily apply a mascara liquid from the root portion present in the mucous membrane near the nasal end of the eyelid. [Technical means to solve the problem]

The mascara applicator of the present invention that achieves the above-mentioned object is provided with: a holding part that is held by the user's fingers, a shaft extending from the holding part toward one axis, and a coating part that is arranged at the front end of the shaft. , the application part has: a core part extending from the front end of the shaft part in an arc shape and a plurality of bristles protruding from the entire circumference of the curved core part, and the mascara applicator has It is characterized in that the front end of the core is arranged so as to coincide with the extension line of the shaft, and the three-dimensional shape formed by the tips of many bristles protruding from the substantially entire circumference of the front end side of the core is directed toward the core. The front end forms a tapered spindle shape.

In the mascara applicator of the present invention, the applicator is formed by a twisted brush with bristles arranged between the core materials for twisting, and the spindle shape is formed by a twisted brush arranged on the core material for multiple rotations. The bristles in the interval can be formed.

In the mascara applicator of the present invention, the three-dimensional shape formed by the tips of the many bristles disposed on the shaft other than the tip side is a wave-like contour having repeated convex and concave portions along the long direction of the core. What is necessary is just to form the imaginary curve which connects the apex of several convex parts to be the same as the curved shape of a core part. At this time, the height difference between the convex part and the concave part was 3.9 mm or less. [Effect of the invention]

According to the mascara applicator of the present invention, since the front end of the core is arranged in line with the extension line of the shaft, when the user holds the holding part so that the applicator is close to the edge of the upper and lower eyelids, the user can easily The position of the tip of the applicator is grasped, and the position of the tip of the applicator does not change even if the angle around the axis deviates when the user holds the holding unit. Therefore, it is easy to bring the front end of the application part close to the nose-side edge vicinity of the upper and lower eyelids.

Moreover, the three-dimensional shape formed by the tips of many bristles protruding from the substantially entire circumference of the front end side of the core has a spindle shape that tapers toward the front end of the core, so the bristles near the front end are closer to the core. The front end side of the hair becomes shorter, and the hair tip is inclined with a certain slope. Therefore, when the front end side of the application part is brought close to the nose-side end vicinity of the eyelid, the bristle tips of the bristles on the front end side of the application part are easily arranged along the edge of the eyelid near the end part. Therefore, it is possible to provide a mascara applicator that can easily apply a mascara liquid from the roots of the eyelashes arranged in the mucous membrane near the end of the eyelid on the nasal side.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a side view of a mascara applicator according to the present embodiment, and FIG. 2 shows a partial enlarged view of the front end side of the applicator of the mascara applicator.

As shown in FIG. 1 , the mascara applicator 10 of this embodiment is provided with: a holding portion 11 held by the user's fingers, a shaft portion 12 extending linearly from the holding portion 11 toward the axis L direction, and a shaft portion provided on the shaft portion. 12 of the coating portion 13 of the front end.

The coating part 13 has: a core part 14 extending from the front end of the shaft part 12 in an arc shape such as a circular arc, an elliptical arc, or a parabola; Many bristles 15 are provided.

The core 14 has a curved shape slightly corresponding to the shape of the mucous membrane of the upper and lower eyelids of an adult, and the width of the curved portion is formed to be equal to the width of the mucous membrane of the upper and lower eyelids of an adult. The application portion 13 is arranged so that the tip of the core portion 14 is on the extension line of the shaft portion 12, ideally aligned with the axis L. As shown in FIG.

The coating portion 13 of this embodiment is formed by a twisted brush in which a plurality of bristles 15 are continuously arranged between a pair of core materials 14a, 14a formed of thin metal wires and connected at their tips. In the application portion 13 , the bristles 15 are arranged so as to be continuous with the entire curved portion of the core 14 , and each bristle 15 protrudes radially on both sides in a direction substantially perpendicular to the core 14 . By twisting the core materials 14a, 14a, a large number of bristles 15 are arranged to protrude substantially from the entire circumference in a helical shape. Therefore, the hair tips of the many bristles 15 arranged substantially all around the core 14 have a three-dimensional shape.

The three-dimensional shape formed by the tips of many bristles 15 roughly has the shape of a rotating body centered on the core 14 . In the embodiment, substantially the entire circumference of the front end side of the core 14 is formed into a three-dimensional shape by the tips of many bristles 15 arranged in the section where the pair of core materials 14a, 14a are twisted more than a plurality of times. It has a spindle shape tapered toward the tip of the core 14 . The spindle shape is also a conical shape, and may be a polygonal spindle shape, but in this embodiment, it is a so-called pyramid shape formed into a pyramid shape.

The pyramid shape is formed around the front end side of the core part 14, and it is formed like a small vase that can be used for pottery, for example, using a potter's wheel.

The three-dimensional shape around the core 14 except the front end side is that 3 to 5 convex parts 16 and concave parts 17 of substantially the same shape are repeatedly provided along the long direction of the core part 14, and it is seen from the side periphery of the wave side. The outline shape has a wave shape. The contour of each convex portion 16 is formed as a convex curve such as circular arc, elliptical arc, or parabola, and the concave portion 17 between adjacent convex portions 16 is also formed as a convex curve such as circular arc, elliptical arc, or parabola.

For the bristles 15 used in this embodiment, linear nylon bristles can be used. Although there is a comb-type structure in the past, it is not a comb-type in the present embodiment, but this nylon hair is installed on the core material 14, so more mascara liquid 18 can be entangled and kept easily, and This can be applied without exception to the soft and thin new eyelashes such as lanugo. Also, since it is a mascara applicator that is particularly suitable for the structure of mucous membranes, it has a softer touch on the skin of mucous membranes than a comb type, so it is less likely to be injured.

The distance from the core 14 of the three-dimensional outline of this embodiment, that is, the protruding length of the many bristles 15 protruding from the core 14 in a direction perpendicular to it, is preferably set at 0.1 mm to 4 mm. If the protruding length of the bristles from the core part 14 is too long, it will be difficult for the application part 13 to approach the root of the eyelashes when the mascara liquid 18 is applied. On the other hand, if it is too short, the force of entanglement with the liquid mascara 18 will be weakened, and it will take time to apply it. Therefore, a moderate length is necessary.

Also in the present embodiment, the height difference of the waveform in which the concave portion 17 and the convex portion 16 of the contour of the three-dimensional shape alternately repeats is the distance farthest from the core portion 14 of each convex portion 16, that is, the distance from the core portion 14. The length of the bristles 15 protruding most towards the orthogonal direction, the closest distance from the core 14 in each recess 17, that is, the maximum width of the length of the bristles 15 protruding the least towards the orthogonal direction from the core 14 The width is set below 3.9mm.

If the maximum width of the waveform height difference is too large, the curvature of the three-dimensional shape of each convex part 16 will become larger, and the area close to the edge of the eyelid will become narrower, so that the mascara liquid 18 can be applied to the root of the eyelashes. narrowed. On the other hand, if the height difference of the waveform is too small, then when the mascara liquid 18 is applied, the amount of the mascara liquid 18 accumulated in the application part 13 will be reduced, and it must be frequently contacted with the mascara contained in the container not shown. The liquid mascara 18 takes time to apply.

Furthermore, although the outline of the three-dimensional shape of the many bristles 15 constituting the application portion 13 has a wave pattern in which the concave portion 17 and the convex portion 16 alternately repeat, but in the same phase around the core portion 14 connecting the plurality of convex portions 16 The imaginary curve C at the top of each convex portion 16 is formed substantially in parallel with the same shape as the curved shape of the core portion 14 .

According to the mascara applicator 10 of the present embodiment as described above, since the front end of the core part 14 is arranged in line with the extension line of the shaft part 12, when the user holds the holding part 11 and makes the applicator part 13 close to the top and bottom The user can easily grasp the position of the tip of the applicator 13 at the edge of the eyelid, and the position of the tip of the applicator 13 will not change even if the angle around the axis is shifted when the user holds the holding unit 11. . Therefore, it is easy to bring the front end of the applicator 13 close to the nose-side end vicinity of the upper and lower eyelids.

Also, the three-dimensional shape formed by the tips of many bristles 15 arranged on the substantially entire circumference of the front end side of the core 14 has a spindle shape that tapers toward the front end of the core 14, so the bristles near the front end 15 becomes shorter toward the front end side of the core portion 14, and the tip of the hair is inclined with a certain slope. Therefore, when the tip side of the applicator 13 is brought close to the nasal end of the upper and lower eyelids, the tips of the bristles 15 on the tip side of the applicator 13 are easily arranged along the edge of the eyelid near the end. Therefore, the mascara applicator can easily apply the mascara liquid 18 from the roots of the eyelashes arranged in the mucous membrane near the nasal end of the upper and lower eyelids.

Also, in the mascara applicator 10 of this embodiment, although the average thickness of the mucous membrane of the human eyelid is about 2 mm, the mascara can be applied from the growth edge of the eyelashes at the root of the root because it is shaped to match the mucous membrane. Liquid 18. In this embodiment, the bristles 15 are arranged along the shape of the mucous membrane of the eyelid to fit the thickness of the mucous membrane, and the bristles 15 are provided with convex and concave shapes, so that the mascara 18 is easily contained. And, by making the tip into a so-called pyramid shape with a tapered tip, a structure that can directly reach the lanugo part of the inner corner of the eye, which was not possible in the past, is formed. That is, since the composition is made most suitable for the mucous membrane of the eyelid, it becomes possible to apply from the growth edge of the eyelashes which grow out of the mucous membrane.

In the mascara applicator 10 of the present embodiment, the applicator 13 is formed by disposing the bristles 15 between a pair of core materials 14a, 14a and twisting a twisted brush. The core material 14a, 14a is formed by the bristles 15 in the twisted interval of more than a plurality of rotations. Therefore, a sufficient amount of bristles 15 can protrude in all directions around the core members 14a, 14a at the spindle-shaped front end portion of the application portion 13. Thereby, even if the angle around the axis at the time of application is slightly shifted, the mascara liquid 18 can be more easily applied to the root of the eyelashes in the mucous membranes present near the nasal end of the upper and lower eyelids. part.

Furthermore, in the mascara applicator 10 of the present embodiment, the contour of the three-dimensional shape formed by the tips of the many bristles 15 disposed on the applicator 13 has a wave pattern that repeats unevenness along the longitudinal direction of the core 14. Therefore, the liquid mascara 18 can be easily accumulated in the application part 13 compared to the case where the three-dimensional shape of the application part 13 is formed into a linear cylindrical shape. Moreover, since the imaginary curve C connecting the tops of the plurality of convex parts 16 is set to be equal to the curved shape of the core part 14, the application part 13 can be brought into contact with more eyelashes existing on the edge of the eyelid in a wider range. And it is easy to apply together, and it is easy to save the operation procedure of applying to eyelashes.

In particular, if the maximum width of the corrugated concave portion 17 and convex portion 16 is 3.9 mm or less, it is easy to allow a wider range of the application portion 13 to touch the roots of more eyelashes present in the mucous membrane at the edge of the eyelid. The mascara liquid 18 can be easily applied to the roots of more eyelashes in the mucous membrane, and the procedure of the application operation can be further saved.
