Description

  The present invention relates to a liquid cosmetic container such as mascara. Specifically, the present invention relates to an applicator for applying a mascara liquid, which is provided at the tip of an applicator bar whose rear end is connected to a ceiling portion of a cap.

  Conventionally, when applying liquid cosmetics for mascara, the applicator for mascara has the function of applying liquid cosmetics to the eyelashes, the function of combing the eyelashes to which the liquid cosmetics adhere, and applying or fine-tuning to the details. The function to do was demanded. Therefore, the density of the hair at the tip of the applicator is increased to facilitate fine application (see Patent Document 1), and the eyelashes are easily combed by partially lengthening the hair legs (see Patent Document 2). . In recent years, a molding brush (see Patent Document 3) in which the entire applicator is integrally molded with an elastic resin such as an elastomer resin is becoming mainstream. In many cases, the molding brush has a configuration in which needle-like hairs are arranged substantially in parallel with the axis of the application portion because of the mold structure and mold cost.

  Next, details of the applicator for mascara according to the present invention will be described with reference to FIGS. FIG. 2 is a perspective view of the applicator for mascara of the present invention, and FIG. 3 is a side view. The applicator 4 includes a molding brush portion 42 composed of the above-described base portion 43 and needle-like hair 44, and a connecting portion 41 connected to the applicator rod 3, and is integrated with a thermoplastic resin or a thermosetting resin. It is molded into.

  The connecting portion 41 is inserted into a connecting hole 31 formed at the tip of the application bar 3 and fixed by caulking to fix the applicator 4 to the tip of the application bar 3. A base portion 43 of the molding brush portion 42 is coaxial with the connecting portion 41 and protrudes from the tip of the application rod 3. Needle-like hairs 44 are erected from the base 43.

  The needle-like hairs 44 form a line substantially parallel to the axis B because of the mold to be molded. The rows of the needle-like hairs 44 are arranged over the circumferential direction of the base portion 43 and over the axial direction of the base portion 43. The total number of rows of the needle-like hairs 44 is in the range of 4 to 32 rows. Further, the basic interval (the distance between the hairs, G in FIG. 6) of the needle-like hairs 44 in the row is in the range of 0.05 mm to 1.0 mm.

  As shown in the side view of FIG. 4, the rows of the needle-like hairs 44 are short hair row groups 45 having short hairs in the central region in the axial direction of the forming brush portion 42 (the portion indicated by arrow C in FIG. 3). And the long hair row group 46 having long hairs. Further, when viewed from the side, the long hair row group 46 has an arch having the longest hair foot in the center region (the portion indicated by the arrow C) of the molded brush portion 42 and the shortest hair foot as shown in FIG. It has a shape. Among these, the length of the short hair portion 49 in the tip 61 region (the portion indicated by the arrow D in FIG. 3) is about 1.0 mm to 10.0 mm. And the short hair row group 45 becomes the application part 47 which apply | coats liquid cosmetics A to eyelashes, and the short hair part 49 of the long hair row group 46 becomes the fine application part 48 apply | coated to the detail of eyelashes. Further, the central region of the long hair row group 46 (the long portion of the bristle, the portion indicated by the arrow C) is a comb portion 62 for combing the eyelashes to which the liquid cosmetic A is attached.

  As shown in FIG. 4, the angle of spread of the long hair row group 46 with respect to the circumferential direction (the angle between the needle hairs 44 at both ends of the long hair row group 46) E is relative to the circumferential direction of the short hair row group 45. And the spread angle (angle between the needle-like hairs 44 at both ends of the short hair row group 45) F is smaller. Further, the long hair row group 46 has a comb region 62 that combs the eyelashes in the central region (C arrow portion), so that a sufficient combing (combing eyelash) effect cannot be expected in one row, and its function is exhibited. Requires at least two rows. Moreover, it is necessary to arrange the needle-like hairs 44 in each row in a staggered manner so that the eyelashes are entangled with the needle-like hairs 44.

  Next, the fine application part 48 will be described with reference to the drawings. FIG. 5 is a cross-sectional view of the fine coating portion 48 (the portion indicated by the arrow D in FIG. 3), and FIG. 6 is a diagram illustrating the arrangement of the needle-like hairs 44 and the rows of the fine coating portion 48. In the region of the short hair portion 49 of the long hair row group 46, fine coating rows 40 are added between the rows. The fine coating row 40 is provided between the long hair row groups 46 with a length substantially the same as the length of the short hair portion 49. The length of the needle-like hair 44 of the fine coating row 40 is about 1.0 mm to 10.0 mm. Further, the number of the fine coating rows 40 is one or more. As a result, the density of the needle-like hairs 44 in the fine application part 48 is increased as compared with other places, and the retained amount of the liquid cosmetic A and the fine application property are improved.

  Next, the case where the applicator for mascara of this invention is implemented is demonstrated. First, as a material for the applicator for mascara of the present invention, it is desirable to use a thermoplastic resin or a thermosetting elastomer resin. Specific examples of the thermoplastic resin include resins such as polyethylene, polypropylene, polystyrene, polyethylene terephthalate, polybutylene terephthalate, polycarbonate, and polyacetate. Further, ethylene-based, olefin-based, vinyl chloride-based, urethane-based, amide-based, and the like These thermoplastic elastomer resins can be used. As the thermoplastic elastomer, synthetic rubbers such as urethane rubber, silicon rubber, fluorine rubber, nitrile rubber, chloroprene rubber, and polybutadiene rubber can be specifically used.

  The rows of the needle-like hairs 44 provided on the base portion 43 of the forming brush portion 42 are described as being about 4 to 32 rows, but optimally, there are about 16 rows as shown in FIG. The rows of the needle-like hairs 44 need only be aligned in the direction of the axis B of the base 43, and need not be linear, need not be parallel to the axis B, and do not need to be aligned in parallel. .

  In addition, the basic interval (the length between the hairs, G in FIG. 6) of the needle-like hairs 44 in the row is described as 0.05 mm to 1.0 mm. is there. Further, as shown in FIG. 6, the needle-like hairs 44 in adjacent rows are alternately arranged in a staggered manner so that the needle-like hairs 44 are uniformly arranged so that the needle-like hairs 44 do not overlap. Yes. Therefore, the interval between the needle-like hairs 44 in the row is changed and adjusted as necessary (G ′ in FIG. 6).

  Although it is the length of the acicular hair 44, the length of the acicular hair 44 in the short hair row group 45 is about 0.5 mm to 3.0 mm, and optimally about 1.0 mm to 2.2 mm. The length of the acicular hair 44 in the long hair row group 46 is 1.0 mm to 5.0 mm in the longest region (the portion indicated by the arrow C in FIG. 3), and optimally about 2.0 mm to 4.0 mm. It is. The length of the acicular hair 44 of the short hair portion 49 in the long hair row group 46 is about 0.5 mm to 4.0 mm, and optimally about 1.0 mm to 3.0 mm. The length of the needle-like hair 44 of the fine coating row 40 is about 0.5 mm to 4.0 mm, and optimally about 1.0 mm to 3.0 mm. The length of the needle-like hair 44 of the short hair portion 49 in the long-hair row group 46 is not limited by the length of the needle-like hair 44 of the short-hair row group 45, and is longer than the length of the needle-like hair 44 of the short-hair row group 45. Can be short or long. Similarly, the length of the needle-like hair 44 in the fine application row 40 is not limited by the length of the needle-like hair 44 in the short hair row group 45 or the short hair portion 49.

  In the short hair row group 45, the long hair row group 46, the short hair portion 49, and the fine coating row 40, each row group, each row, and each region match the length of the hair of the acicular hair 44. There is no need. For example, as shown in FIGS. 4 and 5, by changing the length of the needle-like hair 44 between the groups, it is possible to make an arc shape different from the arc shape when the same length is arranged, The feeling of application such as stiffness of the hair 44 and the liquid content of the liquid cosmetic A are improved.

  The lengths of the needle-like hairs 44 in the long hair row group 46 and the short hair row group 45 may be clearly distinguished, and conversely, as shown in FIG. 4, the short hair row group 45 is in contact with the long hair row group 46. It is also possible to gradually increase the length of the portion of the needle-like hair 44 and eliminate the step between the short hair row group 45 and the long hair row group 46. In this case, the distinction between the long hair row group 46 and the short hair row group 45 is unclear, but there is no need to clarify the boundary between them, and as shown in the cross-sectional view of FIG. A portion in which the hair length is like a mohawk may be considered as the long hair row group 46.

  In addition, when the above-mentioned 16 rows of the needle-like hairs 44 are provided on the entire circumference, the long hair row group 46 is 5 rows and the short hair row group 45 is the remaining 11 rows. Then, as shown in FIG. 4, when the rows (16 rows) of needle-like hairs 44 are evenly arranged in the circumferential direction of the base 43, the angle of the rows of needle-like hairs 44 with respect to the circumferential direction The interval is 22.5 °. Furthermore, when the number of long hair row groups 46 and short hair row groups 45 in all 16 rows is 5 rows and 11 rows as described above, the angle of spread of the long hair row group 46 with respect to the circumferential direction E is 90 °, and the spread angle F with respect to the circumferential direction of the short hair row group 45 is 225 °. Although the case where the row | line | column of the acicular hair 44 was arrange | positioned equally was demonstrated above, it is not necessary to arrange | position a row | line | column equally.

  Next, an example of the fine application part 48 will be described. The fine application row 40 is provided in the short hair portion 49 of the long hair row group 46, but is arranged between the long hair row group 46 rows as shown in FIGS. 5 and 6. In the figure, two fine application rows 40 are arranged on both sides of the central long hair row group 46. This number can be set freely. Moreover, although the length of the fine application part 48 and the fine application row | line | column 40 was said to be about 1.0 mm thru | or 10 mm, respectively, it is about 3.0 mm thru | or 7.0 mm respectively optimal. However, it is not necessary to make the lengths of the fine coating portion 48 and the fine coating row 40 coincide.

  The needle-like hairs 44 in the adjacent rows are alternately arranged in a staggered manner, and the needle-like hairs 44 are arranged uniformly. However, as shown in FIG. The interval between the needle-like hairs 44 in the row adjacent to the fine coating row 40 (part of the long-hair row group 46) is changed (G to G 'to G), and the staggered arrangement of the needle-like hairs 44 in the long-hair row group 46 is maintained. doing.

  As described above, the minimum configuration of the fine coating unit 48 is that the long hair row group 46 is two rows and the fine coating row 40 is one row. In addition, when the fine application | coating row | line | column 40 is two or more rows, it is desirable to arrange | position the fine application | coating part 40 1 row at a time between the row | line | columns of the long hair row | line | column group 46. FIG. In addition, when the number of rows of the fine coating row 40 is smaller than the number of rows of the long hair row group 46, it is not necessary to arrange the fine coating row 40 symmetrically in accordance with the center of the short hair portion 49, and the short hair It may be arranged so as to be offset to one side of the portion 49. That is, it is not necessary to configure the fine application portion 48 using all the rows of the short hair portions 49 of the long hair row group 46, and the fine application portion 48 can be provided partially using a part of the rows. It is.
