- However, conventional mascara applicators were designed with a brush shape that allows easy application of mascara liquid from the middle of the eyelashes to the tip side. Therefore, it was not sufficient for any growth process of eyelashes, including grown hairs and laying hairs present in eyelid lashes. Although human eyelashes grow out of the mucous membrane of the eyelids, it is difficult and time-consuming to apply mascara from the edge of the eyelashes. In particular, applying mascara from the short eyelashes near the nasal edge of the upper and lower eyelids and from the base of the eyelashes that exist in the mucous membrane is notably time-consuming.
- The purpose of the present invention is to provide a mascara applicator that can easily apply mascara liquid from the root portion that exists within the mucous membrane near the nasal edge of the eyelid.
- In order to achieve the above-mentioned purpose, a mascara applicator comprising: a holding part held by a hand and fingers; a shaft part extending in one axial direction from the holding part; an application part provided at the tip of the shaft part; and wherein the application part comprising a core part extending from the tip of the shaft part and curved into an arc shape, and a plurality of brush bristles arranged to protrude around the entire curved core part; wherein the tip of the core part is arranged so that the tip of the core part coincides with the extension of the shaft part, and the three-dimensional shape consisting of the tip of a plurality of any brush bristles protruding around the entire tip of the core part has a weight shape that tapers toward the tip of the core part.
- In the mascara applicator of the present invention, the application part comprises a twisted brush with the brush bristles arranged between the core part and the weight shape is formed by the brush bristles arranged in the section where the core part is twisted more than one rotation.
- In the mascara applicator of the present invention, the three-dimensional shape consisting of the tip of a plurality of the brush bristles arranged on the shaft except for the tip side has a waveform contour that repeats convex parts and concave parts along the longitudinal direction of the core part, and the virtual curve connecting the tops in a plurality of the convex parts is formed to be the same as the curved shape of the core part.
- In this case, the height difference between the convex part and the concave part of the waveform may be 3.9 mm or less.
- According to the mascara applicator of the present invention, the tip of the core part is arranged to coincide with the extension of the shaft part, so that when the user holds the holding part and brings the application part close to the edge of the upper and lower eyelids, the user can easily grasp the position of the tip of the application part, and the tip position of the application part does not change even if the angle is shifted around the shaft part while holding the holding part. This makes it easy to bring the tip of the application part close to the nasal edge of the upper and lower eyelids.
- Moreover, since the three-dimensional shape consisting of the tip of a plurality of brush bristles protruding around the entire tip of the core part has a weight shape that tapers toward the tip of the core part, the brush bristles near the tip become shorter toward the tip of the core part, and the tip is inclined at a constant gradient. Therefore, when the tip of the application part is placed near the nasal edge of the eyelid, the tip of the brush bristles at the tip of the application part can be easily positioned along the edge of the eyelid near the edge.
- Thus, it is possible to provide a mascara application tool that can easily apply mascara liquid from the root portion of eyelashes that exist side by side in the mucous membrane near the nasal edge of the eyelid.

FIG. 1 is a side view of the mascara applicator which is one embodiment of the present invention. -
FIG. 2 is a partially enlarged view of the tip side of the application part of the mascara applicator which is one embodiment of the present invention. - The following is a detailed description of the embodiment of the present invention with reference to the figures.
-
FIG. 1 is a side view of the mascara applicator of this embodiment, andFIG. 2 is a partially enlarged view showing the tip side of the application part of the mascara applicator. - As shown in
FIG. 1 , themascara applicator 10 of this embodiment consists of aholding part 11 that is held by the user's hand and fingers, ashaft part 12 that extends linearly from theholding part 11 in the direction of the axis L, and anapplication part 13 provided at the tip of theshaft part 12. - The
application part 13 has acore part 14 extending from the tip of theshaft part 12 in a curved arc shape such as a circular arc, elliptical arc, parabola, etc., and a plurality ofbrush bristles 15 arranged along thecore part 14 so that they protrude from thecore part 14 in an orthogonal direction. - The
core part 14 has a curved shape that roughly corresponds to the shape of the mucous membranes of the upper and lower eyelids of adults, and the width of the curved portion is formed to be equivalent to the width of the mucous membranes of the upper and lower eyelids of adults. - In this
application part 13, the tip of thecore part 14 is arranged so that it matches the extension of theshaft part 12, preferably on the axis L. - The
application part 13 of this embodiment consists of a twisted brush made of metal thin wire, etc., formed by twisting a plurality ofbrush bristles 15 continuously arranged between a pair ofcore materials - In this
application part 13,brush bristles 15 are arranged so as to be continuous over the entire curved portion of thecore part 14, and eachbrush bristles 15 projects radially in both orthogonal directions relative to thecore part 14. By twisting thecore material 14 a, a plurality ofbrush bristles 15 is arranged in a spiral shape protruding around the entire circumference. Thus, the tip of a plurality ofbrush bristles 15 arranged around the entire circumference of thecore part 14 has a three-dimensional shape. - The three-dimensional shape of the tip of a plurality of
brush bristles 15 has a rotational body shape centered on thecore part 14 roughly. In this embodiment, around the entire tip side of thecore part 14, the three-dimensional shape consisting of the tips of a plurality ofbrush bristles 15 arranged in a section where a pair ofcores core part 14. The weight shape can be a cone shape or a polygonal pyramid shape, but in this embodiment, it is formed in a polygonal pyramid shape, called pyramidal shape. - To form a pyramidal shape all around the tip side of the
core part 14, it can be formed, for example, like a ceramic single flower vase that is finished using a potter's wheel. - In the three-dimensional shape around the
core part 14, except for the tip side, three to fiveconvex part 16 andconcave parts 17 of the same shape are repeated along the longitudinal direction of thecore part 14, and the contour shape seen from the side periphery of the wave side has a waveform. The contour of eachconvex part 16 is formed into a convex curve such as a circular arc, elliptical arc, parabola, etc., and theconcave part 17 betweenadjacent convex parts 16 is also formed into a convex curve such as a circular arc, elliptical arc, parabola, etc. - Straight nylon bristles can be used as the
brush bristles 15 in this embodiment. - Although a comb-type structure has existed in the past, in this embodiment, it is possible to hold a large amount of
mascara liquid 18 easily by attaching the nylon bristles to thecore part 14 instead of a comb-type structure. It makes it possible to apply the mascara all over the eyelashes, even to newborn eyelashes that are soft and fine-laying hairs. In addition, the mascara applicator is particularly suitable for mucous membrane structures because it is gentler on the skin and less likely to damage mucous membrane areas than a comb-type. - The length of a plurality of
brush bristles 15 protruding in the orthogonal direction from thecore part 14 of the contour of the three-dimensional shape of this embodiment should be between 0.1 mm and 4 mm. When applying themascara liquid 18, it will be difficult to bring theapplication part 13 close to the root of the eyelashes if the brush bristles projecting from thecore part 14 are overly long. On the contrary, if it's too short, the impregnation force that holds themascara liquid 18 in place will be diminished, and application will take longer. As a result, a modest length is required. - In addition, the height difference of the waveform repeated alternately in which the
concave part 17 and convexpart 16 of the three-dimensional shape contour in this embodiment, that is, the maximum width between the furthest distance from thecore part 14 in each convex part 16 (the length of thebrush bristles 15 protruding from thecore part 14 in the orthogonal direction) and the furthest distance from thecore part 14 in each concave part 17 (the length of thebrush bristles 15 protruding from thecore part 14 in the orthogonal direction) should be 3.9 mm or less. - If the maximum width of the height difference of the waveform is too large, the curvature of the three-dimensional shape of each
convex part 16 becomes larger, resulting in a narrower area that can be placed close to the edge of the eyelid and a narrower area where the mascara liquid 18 can be applied to the root portion of the eyelashes. - On the other hand, if the height difference of the waveform is too small, the amount of
mascara liquid 18 stored in theapplication part 13 becomes small when applyingmascara liquid 18, and themascara liquid 18 stored in the container, which is not shown in the figure, must be frequently contacted, making the application time-consuming. - Moreover, although the contour of the three-dimensional shape of a plurality of
brush bristles 15 that make up theapplication part 13 has a waveform alternately repeated withconcave part 17 and convexpart 16, the virtual curve C connecting the tops of eachconvex part 16 at the same phase around thecore part 14 in a plurality ofconvex parts 16 is formed to be roughly parallel to the same shape as the curved shape of thecore 14. - According to the
mascara applicator 10 of this embodiment as described above, the tip of thecore part 14 is arranged to coincide with the extension of theshaft part 12, so that when the user holds theholding part 11 and brings theapplication part 13 close to the edge of the upper and lower eyelids, the user can easily grasp the position of the tip of theapplication part 13, and the tip position of theapplication part 13 does not change even if the angle is shifted around the shaft part while holding theholding part 11. This makes it easy to bring the tip of theapplication part 13 close to the nasal edge of the upper and lower eyelids. - Moreover, since the three-dimensional shape consisting of the tip of a plurality of
brush bristles 15 protruding around the entire tip of thecore part 14 has a weight shape that tapers toward the tip of thecore part 14, thebrush bristles 15 near the tip become shorter toward the tip of thecore part 14, and the tip is inclined at a constant gradient. Therefore, when the tip of theapplication part 13 is placed near the nasal edge of the eyelid, the tip of thebrush bristles 15 at the tip of theapplication part 13 can be easily positioned along the edge of the eyelid near the edge. Thus, themascara liquid 18 can be applied easily from the root portion of eyelashes that exist side by side in the mucous membrane near the nasal edge of the upper and lower eyelids. - Moreover, in the
mascara applicator 10 of this embodiment, the mucous membrane of the human eyelid is about 2 mm on average, and since it follows the shape of this mucous membrane, themascara liquid 18 can be applied from the edge of the eyelashes at the root portion. In this embodiment, the arc follows the shape of the mucous membrane of the eyelid, and the brush bristles 15 are provided to fit the thickness of that mucous membrane, and the brush bristles 15 are given a convex and concave shape to make it easier to store themascara liquid 18. In addition, the pyramid shape with a tapered tip is designed to directly reach previously unreachable laying hairs at the top of the eye. In other words, the eyelid mucous membrane is optimally designed for application from the edge of the eyelashes that grow out of the mucous membrane. - Moreover, in the
mascara applicator 10 of this embodiment, theapplication part 13 consists of a twisted brush with the brush bristles 15 arranged between a pair ofcore materials core materials core materials application part 13. This allows themascara liquid 18 to be applied more easily to the root portion of the eyelashes that exist in the mucous membrane near the nasal edge of the upper and lower eyelids, even if the angle around the axis during application is slightly off. - Furthermore, in the
mascara applicator 10 of this embodiment, since the contour of the three-dimensional shape consisting of the tips of a plurality of brush bristles 15 arranged in theapplication part 13 has a waveform that repeats concave part and convex part along the longitudinal direction of thecore part 14, it is easier to storemascara liquid 18 in theapplication part 13 in this embodiment than in the case where the three-dimensional shape of theapplication part 13 is formed as a straight cylindrical shape. Since the virtual curve C connecting the tops of a plurality ofconvex parts 16 has the same shape as the curvature of thecore part 14, the wider area of theapplication part 13 can come into contact with more eyelashes on the eyelid edge, making it easier to apply the product to the eyelashes collectively and reducing the time and effort required to apply the product to the eyelashes. - In particular, if the maximum width of the
concave part 17 and theconvex part 16 is 3.9 mm or less, it is easier to bring a wider area of theapplication part 13 into contact with the root portion of more eyelashes in the mucous membrane at the eyelid edge, and it is easier to apply themascara liquid 18 to the root portion of more eyelashes in the mucous membrane, reducing the time and effort required for application. -
