Description

    Technical field
  • The present invention relates to a cosmetic implement that uses a brush tip as an application member for cosmetics, making it possible to draw thin lines, for example, in place of lower eyelashes or eyebrows, one line at a time.
    • Background Art
  • Various improvements have been proposed for application tools, including cosmetic implements that use a brush tip as an application member for an application liquid.
  • In particular, in cosmetic implements that uses a brush tip as the application member for cosmetics, from the viewpoints of the uniformity of quality and price of the fibers that make up the brush tip, and also from the viewpoint of the durability of the fibers against solvents, oils, surfactants, etc., contained in the cosmetics, many brush tips are made of bundles of fibers made of synthetic resin.
  • All of the brush tips usable for the application tool and the like shown below have been proposed by the applicant of the present application, and Patent Literature 1 discloses a brush tip in which fibers made of synthetic resin are molded from a thermoplastic resin.
  • That is, in the brush tip disclosed in Patent Literature 1, the base portion of a bundle of fibers made of thermoplastic resin is bundled into a cylindrical shape and heated, thereby forming a heated and melted flange portion at the base portion. This allows for obtaining a brush tip with fibers standing upright in the flange portion.
  • According to the brush tip described in Patent Literature 1, forming the flange portion by heating and melting enables the production of the brush tip with a cohesive overall shape, excellent aesthetics, and no scattering, at low cost and in large quantities. In addition, when this brush tip is used as an application tool for liquid cosmetics, it is possible to obtain beautiful lines (application lines) that have not been achieved with previous brush-shaped application tools, and, for example, it is possible to draw the outline of the lips beautifully.
  • Patent Literature 2 discloses a brush tip in which the brush tip is formed with fibers standing upright in a heat-melted flange portion, similar to the brush tip described in Patent Literature 1, and a portion of the fibers located on the outer periphery is cut off with a cutter or the like, leaving the axial portion of the fiber bundle.
  • With this brush tip, the brush tip can be obtained in which a thin diameter portion is formed at the front tip portion side of the brush tip by the fibers in the axial portion, and a large diameter portion is formed at the base end portion side (flange side) of the brush tip by the remaining fibers located on the outer periphery portion.
  • According to the brush tip disclosed in Patent Literature 2, since there is a large diameter portion made of fibers on the base end portion side surrounding the thin diameter portion, this large diameter portion functions to sufficiently store the application liquid supplied from the barrel side. Therefore, when this brush tip is used as an application tool for liquid cosmetics, it is possible to provide a cosmetic implement that does not cause huskiness or the like in the lines drawn by the cosmetics.
  • In Patent Literature 3, the brush tip is formed with fibers standing upright in a heat-melted flange portion, similar to the brush tip described in Patent Literature 1, and each fiber standing upright in the flange portion is composed of fibers with an irregular cross section that is non-circular.
  • According to the brush tip disclosed in Patent Literature 3, when it is used in a cosmetic implement that contains cosmetics, the brush tip has a recess on the outer surface of the fibers of the irregular cross-section, so that the recess can be sufficiently filled with cosmetics, etc. Therefore, it is possible to provide a cosmetic implement that has a comfortable application feeling and prevents the cosmetic from running out or huskiness.

    Summary of Invention Technical Problem
  • This type of cosmetic implement, which uses the brush tip as the application member, is available in eye cosmetics such as mascara, eyebrow pencils, and eyeliner. Among these, eyeliner is used to draw a line at the edge of the eyelid, accentuating the eye's contour and intensifying the overall impression of the eye area.
  • However, in recent years, there has been an increasing need for cosmetic implements that can draw to reproduce thin lines, thinner than eyeliner, to correspond to lower eyelashes or eyebrows, one line at a time. There is a demand for cosmetic implements that meet this need.
  • Meanwhile, when attempting to use the brush tip to draw extremely thin lines corresponding to the lower eyelashes, eyebrows, etc., the application load (pushing amount) applied to the brush tip varies from person to person, and therefore, it is also desirable to develop the brush tip that minimizes the degree of change in the line width relative to the pushing amount.
  • Thus, the present invention has been made to solve the above-mentioned technical problems, and its main object is to provide a cosmetic implement equipped with a brush tip that makes it possible to draw extremely thin lines corresponding to the lower eyelashes, etc., and that has a small degree of change in the width of the drawn line in response to the application load (pushing amount) applied to the brush tip.
    • Solution to Problem
  • The cosmetic implement according to the present invention, which has been made to solve the above-mentioned problems, is a cosmetic implement comprises a brush tip which is made of a resin fiber bundle at one end portion of a barrel, and is configured so that a liquid cosmetic stored in the barrel can be supplied to the brush tip, and the brush tip has an application portion made of a fiber bundle formed at a front tip portion side for applying the liquid cosmetic, and a flange portion formed at a base end portion side for holding the fiber, wherein
    1. (1) the total volume of the brush tip is 10 to 40 mm3,
    2. (2) the density of the brush tip excluding the flange portion, expressed as [weight of the brush tip excluding the flange portion mg/volume of the brush tip excluding the flange portion mm3], is 0.03 to 0.10, and
    3. (3) the volume of the flange portion is 10 to 25% of the volume of the brush tip, excluding the flange portion.
    Advantageous Effects of Invention
  • The brush tip according to the present invention, provided in the cosmetic implement, is provided with matters specifying the invention that combine the technical features shown in (1) to (3) above.
  • That is, according to the cosmetic implement according to the present invention, by optimizing the shape of the brush tip, the amount of fibers, and the fiber composition, it is possible to ensure an appropriate supplying amount of the liquid cosmetic while suppressing the amount of deformation at the front tip portion of the brush tip in response to the application load (pushing amount) applied to the brush tip.
  • This makes it possible to draw extremely thin lines corresponding to the lower eyelashes, etc., and also makes it possible to realize the cosmetic implement equipped with the brush tip that has little change in the width of the drawn line in response to the application load applied to the brush tip.

    Description of Embodiment
  • A cosmetic implement according to the present invention will be described based on an embodiment in which it is applied to an eyeliner as shown in the drawings.
  • As shown in Fig. 1, this cosmetic implement comprises a barrel 1 formed into a cylindrical shape made of a resin material, and a cap 11 detachably attached to the barrel 1 at one end side of the barrel 1. The cap 11 is then joined to the barrel 1 in a straight line along the longitudinal direction, thereby forming the cosmetic implement having an elongated cylindrical appearance.
  • At one end side of the barrel 1, a cap fitting portion 1a, which has an outer diameter slightly smaller than that of the barrel 1, is formed by integrally molding with the barrel 1, and the front barrel 2 is fitted and attached along the inner surface of the cap fitting portion 1a.
  • That is, as shown in Fig. 1, the rear half portion of the front barrel 2 is formed cylindrically, and the cylindrical portion is fitted along the inner surface of the cap fitting portion 1a, thereby attaching it to the barrel 1. Besides, as shown in Fig. 2, the front half portion of the front barrel 2 is tapered, and a brush tip 21 serving as an application member is attached so as to protrude from the front end portion. Therefore, in this embodiment, the front end portion of the brush tip 21 protruding from the front barrel 2 serves as an application portion for a liquid cosmetic, which will be described later.
  • Note that, the brush tip 21 is inserted from the opening at the base end portion side of the front barrel 2, and a flange portion 21a formed at the base end portion of the brush tip 21(see Fig. 2) abuts against a stepped stopper 2a formed within the front barrel 2, which reduces the inner diameter and positions the brush tip 21 relative to the front barrel 2.
  • Meanwhile, as shown in Figs. 1 and 2, an inner tube 11a that covers the front barrel 2 and the brush tip 21 is integrally molded with the outer casing material of the cap 11, and at the front end portion of the cap 11, a crown 12 is fitted and attached between the outer casing material of the cap 11 and the inner tube 11a.
  • In addition, a cosmetic reservoir portion 1b is formed within the cylindrical body extending from the longitudinal center of the barrel 1 to the cap fitting portion 1a, and a reservoir body (inner cotton) 4 impregnated with the liquid cosmetic is contained within the cosmetic reservoir portion 1b.
  • And a relay core 5 made of a fiber bundle, a molded core, or other members, which is capable of exerting capillary force to guide the liquid cosmetic, is inserted into one end side of the reservoir body 4.
  • A cylindrical core holder 6 made of such as a resin material is attached to the center of the relay core 5 in the longitudinal direction. The core holder 6 is positioned inside the cap fitting portion 1a, between a wall surface 1c formed inside the barrel 1 and perpendicular to the axis (see Fig. 1), and the flange portion 21a of the brush tip 21, thereby positioning the relay core 5 in the axial direction.
  • In addition, the front tip portion side of the relay core 5 is inserted into a shaft hole 21b (see Fig. 2) formed in the brush tip 21.
  • According to the configuration, the cosmetic impregnated in the reservoir body 4 is supplied to the brush tip 21 via the relay core 5.
  • Note that, a pair of air exchange holes (air circulation holes) 7 are formed at axially symmetrical positions between the front tip portion of the cap fitting portion 1a of the barrel 1 and the front barrel 2, which exchange gas and liquid between the outer air and the liquid cosmetic in the cosmetic reservoir portion 1b, allowing the cosmetic to flow smoothly out to the brush tip 21.
  • Furthermore, a tail plug 8 is press-fitted into the rear half portion of the barrel 1 in a liquid-tight manner to prevent the cosmetic from leaking from the rear end opening. The tail plug 8 has a slightly narrower diameter in the center portion, and the front tip portion and rear end portion are expanded in the radial direction, and is attached to the barrel body 1 in a state where it is in close contact with the inner peripheral surface of the barrel 1.
  • Figure 4 shows a single-item configuration of the brush tip as an application member. The brush tip 21 is made by bundling polyester fiber material (PET, PBT, PTT, etc.) or polyamide fiber material (nylon 6, nylon 66, nylon 610, nylon 612, etc.). The bundled base end portion is subjected to a heat treatment to form a circular flange portion 21a that protrudes in a brim-like manner in the outer circumferential direction, and the flange portion 21a holds the individual fibers so as not to come apart.
  • Furthermore, the axial center portion of the flange portion 21a is then hollowed out in a circular shape, thereby removing a portion of the fibers located at the axial center portion and forming a shaft hole 21b at the base end portion side of the brush tip 21. As described above, the relay core 5 is inserted into the shaft hole 21b to guide the liquid cosmetic. The cosmetic impregnated in the cosmetic reservoir body 4 is supplied to the brush tip 21 via the relay core 5.
  • As shown in Fig. 4, the shaft hole 21b is formed on the flange portion 21a side of the brush tip 21, and the relay core 5 is inserted into the shaft hole 21b, thereby forming a cylindrical portion 21c having a substantially uniform outer diameter along the axial direction. Furthermore, the front tip portion side of the brush tip 21 is formed with a tapered portion 21d (the aforementioned application portion of the cosmetic) whose diameter gradually decreases along the axial direction as liquid cosmetic is introduced through the relay core 5.
  • The fibers constituting the brush tip 21 are made of a thermoplastic resin such as polyester or polyamide as described above, and the fibers having a diameter in the range of φ0.05 to 0.20 mm, more preferably φ0.10 to 0.15 mm, are used.
  • In this case, various cross-sectional shapes of the fibers can be used, such as round, triangular, rectangular, pentagonal, hexagonal, elliptical, and even pointed star shapes.
  • The above-mentioned fibers may be used alone or in combination with a blend of several types of fibers.
  • Furthermore, in the brush tip 21 of this embodiment, as shown in Fig. 3, when the amount of fiber constituting the entire brush tip 21 is a (mg), the projection dimension of the front tip portion of the brush tip from the front barrel 2 is b (mm), the diameter of the shaft hole 21b formed in the flange portion 21a is c (mm), the thickness of the flange portion 21a is d (mm), the insertion amount of the relay core 5 into the shaft hole 21b is e (mm), and the fiber blending ratio (weight ratio) of the amount of fiber a constituting the entire brush tip 21 is f, then the following values are set for each.
    • a = 20 mg, b = 5.2 mm + 0.2 mm ,
    • c = 1.35 mm,
    • d = 0.5 mm,
    • e = 4.8 mm, and
    • f = φ0.15 mm round fiber (weight ratio 1.5): φ0.12 mm round fiber (weight ratio 2.5)
  • In the following, the basis for selecting the technical features (1) to (3) described in Claim 1 will be explained for the brush tip 21 used in the cosmetic implement according to the present invention.
  • As parameters for the brush tip 21 in the present invention, (1) the volume V<0> [mm3] of the entire brush tip when it absorbs the liquid cosmetic, (2) the density ρ<f> [mg/mm3] obtained by dividing the weight W<f> [mg] of the brush tip excluding the flange portion 21a by volume V<f> [mm3] of the brush tip excluding the flange portion 21a, and (3) the ratio r <t>[%] of the volume V<t> [mm3] of the flange portion 21a to the volume V <f> [mm3] of the brush tip 21 excluding the flange portion 21a is defined.
  • The volume (V<0>) of the entire brush tip after absorbing the liquid cosmetic and the volume (V<f>) of the brush tip 21, excluding the flange portion (21a), were calculated: Brush tip 21 was allowed to absorb the liquid cosmetic. After it was sufficiently dried and solidified, the entire brush tip was scanned with a three-dimensional scanner (METROTOM 800, manufactured by Carl Zeiss AG). In addition, the weight W<f> of the brush tip 21, excluding the flange portion 21a, was measured by cutting the fiber portion of the brush tip 21 and measuring only the flange portion 21a with a weighing scale. The volume V<t> of the flange portion 21a was calculated by measuring its dimensions with an optical microscope (DSX1000 manufactured by Olympus Corporation).
  • The following verification was carried out to determine whether the brush tip 21 described above can produce extremely thin lines suitable for lower eyelashes and the like, which the present invention aims for, with little change in line width in response to the application load applied to the brush tip 21.
  • The width of the drawn line (hereinafter referred to as "drawn line width") B<0.5> [mm] was measured when the brush tip 21 was pressed 0.5 mm against the application surface. The drawn line width was calculated based on the thickness of the eyelashes. Since the maximum was approximately 0.3 mm when the eyelash thickness among 10 subjects was calculated, based on this result, lashes smaller than 0.3 mm were rated as A, and lashes 0.3 mm or larger were rated as D.
  • In addition, the line widths B<0.5> and B<1.0> [mm] were measured when the brush tip 21 was pressed 0.5 and 1.0 mm, respectively, against the application surface. The rate of change s of the drawn line width relative to the amount of pressing of the brush tip 21 against the application surface was calculated, and the rate of change was evaluated.
  • The small rate of change s in the drawn line width means that when using the eyeliner of the present invention, it is possible to apply thin lines with little change in drawn line width regardless of the amount of pressing applied to the skin around the eyes, compared to conventional products. The rate of change was judged to be acceptable if it was equal to or less than that of a conventional example (for example, the eyeliner disclosed in JP 2020-39484 A ). Since the average rate of change in the conventional example was 0.52 (10 evaluations), 0.5 was used as the standard, and values less than 0.5 were rated as A, and values equal to or greater than 0.5 were rated as D.
  • Next, the total consumption amount C of the liquid cosmetic was measured under the condition that the eyeliner equipped with the brush tip of the present invention was used to apply a line of 0.5 mm width and 10 mm length intermittently for 5 m in length. This is to numerically confirm that no application defects occur during use based on the amount of liquid consumption. A case where the consumption amount of the liquid was between 10 mg and 25 mg was rated as A, and a case where the consumption amount of the liquid was less than 10 mg or more than 25 mg was rated as D. When the consumption amount of the liquid was less than 10 mg, huskiness occurred in the drawn line. Meanwhile, when the consumption amount of the liquid is more than 25 mg, bleeding occurred in the drawn line, and the cosmetic applied to the application surface will take a long time to dry.
  • Examples and comparative examples of the brush tips used in the above evaluation are shown in Table 1 and Table 2 below. [Table 1]

  • As is clear from the results in Table 1, it can be confirmed that the eyeliners of Examples 1 to 12, which fall within the scope of the technical matters described in Claim 1, are capable of drawing extremely thin lines, for example, corresponding to the lower eyelashes, compared to the eyeliners of Comparative Examples 1 to 8, which fall outside of the scope of the technical matters. Furthermore, as described in the section of the effect of the invention described above, it can be confirmed that the cosmetic implement equipped with a brush tip 21 that exhibits little change in the width of the drawn line in response to the application load applied to the brush tip 21 can be realized.
  • In addition, according to the eyeliners of the present invention shown as Examples 1 to 12 in Table 1, the consumption amount of liquid cosmetic by the brush tip 21 is appropriately controlled, and it can be confirmed that a cosmetic implement can be realized that does not cause huskiness in the drawn line or excessive bleeding.
