Description

  The present invention relates to a cosmetic brush, and in particular to a cosmetic brush for arranging hairs such as eyelashes before and after applying cosmetics such as mascara so that the hairs are aligned and look beautiful.

  As an applicator currently used for applying mascara to eyelashes, a spiral applicator having a spiral groove cut at the end of a cylinder as in Patent Document 1, such as Patent Documents 2 to 4 There are known scissors-like applicators and comb-like applicators as disclosed in Patent Documents 5-7.

  There is also known a scrubbing applicator configured by planting brush hairs spirally on the outer peripheral surface of a shaft body. Among them, in particular, for the purpose of improving the combing effect by the brush, there is one in which the brush bristles implanted in the shaft body are tapered from the fixed end side toward the free end as in Patent Document 8. .

  Recently, mascara containing fibers has been introduced to increase the volume and length of eyelashes, but all of the applicators with the above shapes are difficult to apply fibers to eyelashes and work well. There is a difficulty that it cannot be applied. In particular, after applying mascara, there was a drawback that a plurality of eyelashes adhered to each other due to the mascara and the eyelashes were not burned one by one.

  In Patent Document 9, an appropriate amount of fibers and cosmetics can be attached to the eyelashes, but the first row and the second row of brush hairs planted in two rows in the application direction respectively. Since the tips are planted in the opposite directions of the front and back in the longitudinal direction, the tip of the brush hair cannot be inserted into the gap between the roots of the eyelashes, which is unsuitable for combing of the eyelashes, so-called combing. In order to obtain a beautiful finish by applying a fiber-filled eyelash cosmetic, it is possible to eliminate defects such as non-uniform or damaging fiber attachment, and to make the attached fiber more alive. It is required to comb the eyelashes one by one so that they are aligned and natural, but this requires combing from the root to the tip of the eyelashes, whereas in the previous structure There is a problem that cannot be done well.

Japanese Examined Patent Publication 54-19442 JP-A-9-238740 Special table 2003-515410 gazette Special table 2003-521982 gazette JP 2001-145515 A JP 2001-231627 A JP 2003-259914 A JP 2004-49906 A JP 2002-125753 A

  The present invention has been made in view of the prior art as described above, and when applying cosmetics such as mascara, it can be dispersed so that the eyelashes after applying mascara in particular do not stick together, and In the case of a mascara containing fibers, it is intended to provide a cosmetic brush that can align the direction of fiber attachment and prevent unevenness.

  In order to solve the above-mentioned problems, the cosmetic brush of the present invention is characterized in that it has a brush portion in which a bristle is arranged perpendicularly to the carrier and in series along the longitudinal direction.

  Furthermore, as the application part, an application part that has a predetermined length in the application direction and has a number of grooves in parallel at a constant pitch that can hold fibers in the cosmetics aligned in the application direction. By combining the brush part and the application part to form an applicator, the eyelashes after applying the mascara can be combed and the eyelashes can be set one by one. When applying the cosmetics, the cosmetics and the fibers can be uniformly applied to the eyelashes by the application part, and the adhesion direction of the fibers can be more elegantly arranged while eliminating the application unevenness by the brush part.

  The bristle can be composed of a conventionally known synthetic resin or a composite material using the same, but in particular, either polybutylene terephthalate or polyamide is used, and the wire diameter is preferably 0.01 mm to 0.20 mm. The length is 0.1 mm to 10 mm.

  Further, the brush part is composed of a plurality of bristles, and in particular, by adopting a so-called tapered bristle formed in a sharp shape, the ease of wrinkling and the ease of wrinkling at the time of application, or the ease of wrinkling is improved. be able to. More specifically, when a part or all of the bristle forming the brush portion is 1.0 mm, 2.0 mm, or 3.0 mm from the bristle tip, the bristle wire diameter is equal to the wire diameter of the maximum wire diameter portion. On the other hand, it is characterized by having a tapered shape having a ratio of 20 to 30%, 30 to 50%, and 50 to 80%, respectively.

  In addition, a part or all of the bristle forming the brush portion has a taper that narrows toward the tip. Here, the taper includes a taper that is thinned to the tip of the bristle, a taper that is thin toward the tip but not sharp, or a wedge that is formed toward the tip. In addition, a shape in which the tip and the base are both narrowed may be used. Also, the cross-section of the bristle is a multilayer structure composed of at least two layers, or a structure having a spiral groove with a twist formed on at least a part of the outer periphery of the bristle, and at least a part of the bristle is crimped. It may be. Moreover, the brush part which consists of a some bristle may be characterized by being comprised from the bristle from which at least 2 or more hair length differs.

  Furthermore, one of the features of the present invention is a method for arranging bristles. As a method of arranging the bristle, either a predetermined interval or random may be used, but it is preferable to correspond to the living pitch of the eyelashes, and particularly when the arrangement pitch of the bristle is set to 0.1 mm to 2.0 mm in the longitudinal direction. When it corresponds to the living pitch of the eyelashes, and one or several bristle can be inserted between the eyelashes, and the number of arrangement of the bristle in the coating direction is two or more. If the arrangement pitch of the bristle application direction is 0.1 mm to 2.0 mm, it is optimal for combing the eyelashes. The bristle before processing has a length of, for example, 0.5 to 40 mm, and can be easily combined in one row while the length is adjusted by back baking that heats and melts the base portion together.

  The number of bristle arrangements is preferably 1 to 3 rows. If the number of arrangements is too large, each bristle does not enter between the eyelashes well, and the eyelashes cannot be combed by the brush portion. Even if a bristle is inserted between the eyelashes, there is a problem in that the fibers attached to the eyelashes are removed when combing. The eyelashes usually have a diameter of about 0.1 mm and are present at a pitch of about 0.4 mm. Further, the eyelashes are present in three stages, and three eyelashes are present in an interval of 0.4 mm. Therefore, if the arrangement pitch of the bristle is smaller than 0.1 mm, the bristle is too dense and the eyelashes do not enter between the bristle, making it difficult to comb. On the other hand, if it is larger than 2.0 mm, the bristle spacing is too wide to spread the eyelashes one by one, and there is a possibility that a plurality of eyelashes are collected and the mascara is applied.

  In addition, in the above description, although the brush part demonstrated as what mainly has the function of combing the eyelashes, it is not restricted to this. Of course, the brush part may also be used as a mascara application part.

  According to the cosmetic brush of the present invention, even when the eyelashes are stuck together by the cosmetics or fibers in the cosmetics and become lumpy or bundled, by the brush part consisting of a plurality of bristle, It is possible to disperse by combing the eyelashes, and to obtain an elegant finish.

  In addition, by providing a coating part in which grooves of a predetermined length are arranged in parallel at a constant pitch, the eyelashes are securely held at the length of the grooves, and the eyelashes are dispersed neatly at a constant pitch and stuck together. Can be aligned so that there is no. By appropriately adjusting the length and depth of the grooves, the amount of cosmetics to be retained can be adjusted, and an appropriate amount can be easily and uniformly applied. Furthermore, since the fibers in the cosmetic can be aligned and held in the application direction (that is, along the eyelashes) by the grooves having a predetermined length, the unevenness of the fibers is prevented and the adhesion direction is aligned. It becomes possible to apply uniformly.

  A preferred embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an example in which the cosmetic brush of the present invention is applied to an eyelash applicator (1), FIG. 2 is an enlarged view of the tip of the applicator (1), and FIG.
