Description

  The present invention relates to a resin-molded mascara brush.

  Conventionally, as a mascara brush for applying mascara cosmetics to the eyelashes, a screw brush in which the brush fibers are spirally wound while being sandwiched between two metal core wires, or a flocking brush in which the brush fibers are flocked on one side of the comb base In addition, a molding brush formed by resin molding so that plate-like comb teeth are arranged in parallel is known (Patent Document 1).

  Compared to mascara brushes that use brush fibers, it is easy to mold the brush part into a desired shape. For example, a comb part in which plate-like comb teeth are arranged in parallel on one side of the comb base part is provided. A mascara brush having a semicircular cross-sectional shape on the opposite surface of the comb base and having a concavo-convex portion that repeats undulations in the longitudinal direction of the brush and a boundary wall at the boundary between the comb portion and the concavo-convex portion has been proposed ( Patent Document 2). As a method for using this mascara brush, first, a mascara cosmetic is attached to the mascara brush using a mascara container with a wiping portion. As a result, the mascara brush is in a state in which the mascara cosmetic is accumulated in the recesses in the concavo-convex portion and the excess mascara cosmetic is wiped off in the comb portion. Therefore, the mascara cosmetic is supplied to the root of the eyelashes using the uneven part, and then the eyelashes are combed at the comb part, and the mascara cosmetic is uniformly applied to the eyelashes.

  However, with conventional molded brushes, the mascara cosmetic cannot be applied in a sufficient amount at the base of the eyelashes, so that a desired volume feeling may not be obtained, and the optimal amount for each of the upper eyelashes and the lower eyelashes. There is also a problem that it is difficult to apply mascara cosmetics.

  On the other hand, an object of the present invention is to supply a sufficient amount of mascara cosmetic to the base of the eyelashes for each of the upper eyelashes and the lower eyelashes, so that a beautiful and voluminous finish can be obtained.

  The present inventor, in a molded brush having a brush portion in which plate-like comb teeth are arranged in parallel, causes each plate-like comb tooth to protrude from the entire circumference of the shaft, and completely separates the disk surfaces of adjacent plate-like comb teeth, In addition, the disk shape is a droplet shape composed of an arcuate region and a triangular region, and the distance (arc side tooth height) between the arc forming the arcuate region and the peripheral surface of the shaft is the peripheral surface of the triangular region and the axial surface When the mascara cosmetic is attached to the mascara brush with the mascara cosmetic container and wiped off with the wiping part of the container, the mascara cosmetic is not in the arcuate region. It is held in a sufficient amount between the comb teeth, but in the triangular region, it can be held only on the root side of the comb teeth and hardly held on the top side, or the holding amount can be reduced. When applying mascara cosmetics to eyelashes When the brush part is applied to the eyelashes from the arcuate region, a lot of mascara cosmetic can be supplied to the base of the eyelashes, and the eyelashes can be favorably combed using the triangular region, and further, the lower eyelashes than the upper eyelashes Since the required amount of mascara cosmetics is small, it has been found that mascara cosmetics can be satisfactorily applied using only the triangular region.

That is, the present invention is a mascara brush having a shaft, a brush portion in which a plurality of plate-like comb teeth are arranged in the longitudinal direction of the shaft in one end region of the shaft, and a grip portion provided at the other end of the shaft,
Each plate-like comb tooth protrudes from the entire circumference of the shaft in a state of being separated from the adjacent plate-like comb teeth, and the shape of the surface viewed from the extension direction of the shaft is an arcuate region formed by an arc and an extended line from both ends of the arc A droplet shape consisting of a triangular region sandwiched between
Provided is a mascara brush in which the distance between the arc and the peripheral surface of the shaft (arc side tooth height) is lower than the distance between the top of the triangular region and the peripheral surface of the shaft (triangular region side tooth height).

  Further, the present invention is a mascara cosmetic comprising the above-described mascara brush, a cylindrical mascara cosmetic container into which the brush part of the mascara brush can be inserted, and a wiping unit provided in the mascara cosmetic container. Thus, there is provided a mascara cosmetic in which the wiping portion has a wiping hole having a diameter larger than the diameter of the arcuate region of the plate-like comb teeth on the tip side of the brush portion and smaller than the major axis of the plate-like comb teeth.

  Furthermore, the present invention is a makeup method for applying mascara cosmetics to the eyelashes using the above-described mascara cosmetic, wherein the arcuate region of the brush part is applied to the root of the upper eyelashes, and the tip of the eyelashes is combed in the triangular region Rotate the brush so that the mascara cosmetic is applied to the upper eyelashes, and the triangular area is applied to the base of the lower eyelashes, and the tip of the lower eyelashes is applied in the triangular area to apply the mascara cosmetics to the lower eyelashes. Provide a mascara makeup method.

  According to the mascara brush of the present invention, the mascara cosmetic can be held between the comb teeth in the arched region having a low tooth height. Therefore, when the mascara brush is applied from the arched region to the root of the upper eyelash, A sufficient amount of mascara cosmetic can be supplied. In this case, it is easy to let the mascara brush approach the base of the upper eyelashes because the arc-side tooth height of the arcuate region is low. In addition, if the eyelashes are combed in a triangular region where the arcuate region and the comb tooth surface continue, the mascara cosmetic is held exclusively on the root side in the triangular region, and the amount of the top eyelash is small, so the upper eyelash Can be arranged well. Therefore, the upper eyelashes can have a beautiful finish with a sufficient volume feeling.

  On the other hand, the lower eyelashes have a lower density of the eyelash fibers than the upper eyelashes and the required amount of mascara cosmetics is small, so that only a triangular area of the mascara brush can be used to achieve a beautiful finish with a sufficient volume feeling.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, but the present invention is not limited to the following embodiments. Moreover, in each figure, the same code | symbol represents the same or equivalent component.

As shown in the drawing, each plate-like comb tooth 20 protrudes from the entire circumference of the shaft 13 in the radial direction of the shaft, and the angle formed by the board surface 21 and the shaft 13 is substantially a right angle. Each plate-like comb tooth 20 is completely separated from the adjacent plate-like comb teeth 20 on the entire surface 21. Therefore, the plate-like comb teeth are erected only on one side of the shaft 13 and the other side is flattened on the former molding brush (Patent Document 1), or the plate-like comb teeth are erected only on one side of the shaft 13. Unlike conventional molding brushes (Patent Document 2) in which corrugated uneven surfaces are formed, mascara cosmetics can be held between the comb teeth of the plate-like comb teeth 20 on the entire circumference of the shaft 13.

  Furthermore, the shape of the board surface 21 of the plate-like comb teeth 20 is formed by a substantially semicircular arcuate region 22 formed by an arc 22a and a triangular region 23 sandwiched by extended lines 23b from both ends 22b of the arc 22a. Although it has a droplet shape, the arc-side tooth height H1 of the plate-like comb teeth in the arcuate region 22 is lower than the triangular-region side tooth height H2 of the plate-like comb teeth at the top 23a of the triangular region. The tooth height is sufficient to hold the mascara cosmetic A in between. Here, the preferable tooth height of the plate-like comb teeth 20 is 0.4 to 1.0 mm in the arcuate region 22 and 1.5 to 3.8 mm in the top 23a of the triangular region.

  As shown in FIG. 3 (a) in which the region P1 in FIG. 2 is enlarged by raising the comb teeth in the arcuate region 22 as described above, the mascara cosmetic A that can be held between the comb teeth in the arcuate region 22 is formed. The amount of teeth is higher than the amount of mascara cosmetic A that can be held by the uneven portions of the conventional mascara brush 10x shown in FIG. The distance W1 of the tooth disk surface may be large and increase. Therefore, according to the mascara brush 10A, it is possible to supply a large amount of mascara cosmetics to the root of the eyelashes using the arch-shaped region 22 having a low tooth height that is easy to approach the root of the eyelashes. In particular, according to the arcuate region 22, it is possible to easily approach details such as the corners of the eyes and the eyes.

  The shape of the droplets on the surface 21 of the plate-like comb teeth 20 is preferably triangular because it can be easily inserted into the eyelashes, can be finely adjusted while whisking the eyelashes, and can easily approach the details. The extending lines 23b that are two substantially linear edges of the region 23 are respectively tangents at both ends 22b of the arc 22a of the arcuate region 22. At this time, the angle .theta.1 between the two edges 23b is preferably 30.degree. To 90.degree., And more preferably 45.degree.

  Further, when wiping the plate-like comb teeth 20 with the wiping unit 4, the center of the arc 22 a of the arcuate region 22 of the plate-like comb teeth 20 and the shaft 13 are provided in order to uniformly hold the mascara cosmetic between the comb teeth. It is preferable to match the center of the.

  The preferable diameter of the shaft 13 is 1.5 to 2.2 mm. Therefore, the entire diameter D1 of the arcuate region is 2.6 to 4.0 mm, and the long diameter D2 of the entire plate-like comb teeth is 4.5 to 6.0 mm. It is preferable that

  The distance W1 between the opposing board surfaces 21 of the adjacent plate-like comb teeth 20 is set to 0.3 to 0.7 mm from the viewpoint of the holding amount between the comb teeth of the mascara cosmetic and the ease of wrinkling of the eyelashes by the brush portion 11. The arrangement pitch of the plate-like comb teeth 20 is preferably 0.4 to 1.0 mm.

  In this mascara brush 10A, in the tip region 11b of the brush portion 11, the triangular region side tooth height H2 of the plate-like comb teeth 20 is gradually lowered toward the brush portion tip 11a. In the region 11b, approach to the eyelashes is facilitated not only in the arcuate region 22 but also in the triangular region 23. In addition, in the tip region 11b of the brush portion 11, the diameter of the shaft 13 is also gradually reduced toward the brush portion tip 11a, thereby reducing the amount of mascara cosmetic held between the comb teeth in this region. It is preventing. In this case, from the point that it is easy to approach the details such as the corners of the eyes and the eyes, and to easily insert the mascara brush 10A into the mascara cosmetic container 2, the envelope of the top 23a of the triangular region of the plate-like comb teeth 20 and the shaft 13 Is preferably 5 to 30 °.
