Description

  The present invention relates to a mascara brush provided with a brush for applying mascara liquid to the eyelashes and comb teeth for uniformly spreading the eyelashes and the mascara liquid.

  This type of mascara brush is known from US Pat. There, a mascara brush is constituted by a plastic-molded brush base, a comb disposed on one side of the peripheral surface of the brush base, and a brush mounted along the central axis of the brush base. The brush base is integrally provided with a front end boss and a base end boss, and a comb frame and a reinforcing frame connecting both the bosses. The comb frame and the reinforcing frame are arranged at opposed positions around the brush base, and an opening is formed between the frames as a bristle window for exposing the brush bristles.

  Regarding the present invention, it is known in Patent Documents 2 and 3 to provide comb teeth at the tip of the coating shaft. The comb teeth in the applicator of Patent Document 2 are provided so as to protrude laterally from the application shaft. In the applicator of Patent Document 3, a comb-tooth portion is formed at the tip of a brush-like applicator, and this applicator is used for applying a hair dye solution to eyebrows. The comb-tooth portion protrudes along the central axis of the applicator. In addition to the above, Patent Document 4 discloses an eyebrow brush that fixes a pile hair softer than a brush hair to the tip of the brush by an electric flocking method.

  Since the mascara brush of patent document 1 arrange | positions the comb provided with a group of comb teeth on the peripheral surface side of the brush, when the mascara brush is pulled out from the mascara liquid container, the comb portion is easily caught on the ironing member. Take the trouble. In addition, it is difficult to sufficiently scrape off the mascara held by the brush with the ironing member because the comb portion is in the way, and the mascara is likely to be excessively applied to the eyelashes. In addition, when combing the eyelashes sideways, many eyelashes are combed simultaneously with a group of comb teeth. For this reason, even the eyelashes that have not been combed once have been combed, there is a possibility that the finished state may change by combing again, and it took time and effort to evenly comb all the eyelashes. For example, even when removing the semi-solidified mascara mass captured between the eyelashes, even the already-lashed eyelashes are combed with comb teeth.

  The applicator of Patent Document 2 is composed only of comb teeth. Therefore, in order to apply the mascara solution to all eyelashes, it is necessary to repeatedly apply the mascara solution held on the comb teeth to the eyelashes, which takes a lot of time and effort.

  An object of the present invention is to provide a brush body for applying mascara liquid to the eyelashes and a comb piece for uniformly spreading the eyelashes and the mascara liquid so that the process from the application of the mascara liquid to the finishing of the eyelashes can be performed accurately and simply. It is to provide a mascara brush with excellent usability. The object of the present invention is to allow the mascara brush to be easily put in and out of the mascara liquid container, despite having the comb piece, and to sufficiently scrape off the mascara liquid held by the brush with the ironing member. An object of the present invention is to provide a mascara brush capable of applying an appropriate amount of mascara liquid to the eyelashes.

  The mascara brush of the present invention includes a brush body 5 in which brush hairs 12 project around a core shaft 11 and a comb piece 6. The comb piece 6 is integrally provided with a connecting boss 16 and a plurality of comb teeth 17 protruding from the outer surface of the connecting boss 16. The connecting boss 16 of the comb piece 6 is attached and fixed to the tip of the core shaft 11.

  The brush body 5 includes a core shaft 11 twisted in one direction and brush hairs 12 that are spirally fixed around the core shaft 11. A connecting shaft portion 13 that does not hold and fix the brush bristles 12 is provided at the protruding end of the core shaft 11. Thus, the comb piece 6 is welded and fixed to the brush body 5 in a state where the connecting shaft portion 13 and a part of the brush hair 12 adjacent to the connecting shaft portion 13 are fitted into the connecting boss 16.

  In the present invention, a comb piece 6 is constituted by the connecting boss 16 and a plurality of comb teeth 17 protruding from the outer surface of the connecting boss 16, and the comb piece 6 is attached to the tip of the core shaft 11 of the brush body 5. A fixed mascara brush was obtained. Thus, according to the mascara brush in which the comb piece 6 is fixed to the tip of the core shaft 11, after the mascara liquid held in the brush body 5 is applied to the eyelashes, the eyelashes and the mascara liquid are evenly distributed with the comb teeth 17. Since it can be prepared, it can be performed accurately and simply from application of mascara solution to finishing of eyelashes. Further, since the comb piece 6 is fixed to the tip of the core shaft 11, when the mascara brush is taken in and out of the mascara liquid container 1, the comb piece 6 is well prevented from being caught on the ironing member 3, and usability can be improved. Furthermore, the mascara liquid held by the brush hairs 12 can be sufficiently scraped off by the ironing member 3, and an appropriate amount of mascara liquid can be applied to the eyelashes as intended by the user.

  According to the comb piece 6, which is formed with a tapered comb base portion 18 at the protruding end of the connecting boss 16, and comb teeth 17 extending in parallel with the center of the core shaft 11 are provided on the outer surface of the comb base portion 18. The comb teeth 17 can be prevented from protruding outward from the peripheral surface of the connecting boss 16. Therefore, when the mascara brush is taken in and out of the mascara liquid container 1, the comb piece 6 can be more reliably prevented from being caught by the ironing member 3, and the same ease of use as a conventional mascara brush without a comb piece or comb is provided. Can be demonstrated. Further, since the comb base portion 18 is formed in a tapered shape, the mascara liquid scraped off by the comb teeth 17 or the solidified mascara is prevented from accumulating in the comb base portion 18, and the comb teeth 17 are used. The eyelashes and mascara can be smoothly poured.

  According to the comb piece 6 in which the front and rear surfaces 17a and 17b of the comb teeth 17 are formed as curved surfaces or corrugated surfaces, the protrusions of the comb teeth 17 are biased to either the front or the back. Can be delicately arranged. Moreover, the curl shape of the eyelashes can be adjusted in a state where the eyelashes are received by the curved surface or the corrugated surface.

  According to the comb piece 6 that forms the flank 20 at the connection end of the connection boss 16, the comb piece 6 is more reliably prevented from being caught by the ironing member 3 when the mascara brush is pulled out from the mascara liquid container 1. The brush can be taken in and out more smoothly.

  In the state where the connecting shaft portion 13 that does not hold and fix the brush hair 12 is provided at the protruding end of the core shaft 11 and the comb piece 6 is welded and fixed to the connecting shaft portion 13, the connecting shaft portion 13 and the brush hair adjacent to the connecting shaft portion 13 are provided. If a part of 12 is fitted into the connecting boss 16, it can be thermally deformed when the connecting shaft portion 13 is heated, or the melted bristle 12 can be concealed by being pushed into the welding hole 19. 12 can be eliminated from the outer surface, and the appearance of the brush body 5 including the comb piece 6 can be improved.

(Example) FIG. 1 thru | or FIG. 4 shows the Example of the mascara brush which concerns on this invention. In FIG. 2, reference numeral 1 denotes a mascara liquid container, reference numeral 2 denotes a cap that opens and closes the entrance / exit of the mascara liquid container, and reference numeral 3 denotes a squeezing member provided inside the mascara liquid container 1. A mascara brush is fixed inside the cap 2. The mascara brush includes a holder 4 fixed inside the cap 2, a brush body 5 fixed to the lower end of the holder 4, and a comb piece 6 fixed to the lower end (tip) of the brush body 5. The holder 4 is made of a plastic molded product, and a knob 9 is integrally formed on the upper end of a coating shaft 8 that is long in the vertical direction. This knob 9 is fixed to the cap 2.

  The brush body 5 is composed of a core shaft 11 formed by twisting a wire material folded in one direction in one direction, and brush bristles 12 fixed in a spiral shape around the core shaft 11. The core shaft 11 is made of a stainless steel wire. The outline of the bristle 12 projecting around the core shaft 11 is generally cylindrical, but its lower half is tapered toward the tip.

  The protruding end of the core shaft 11 has a portion where the bristle 12 is not held and fixed, and this portion is used as a connecting shaft portion 13 for mounting and fixing the comb piece 6. A portion that does not hold and fix the brush bristles 12 is also formed at the base end of the core shaft 11 by twisting the previous wire, and this portion is an attachment for welding and fixing the brush body 5 to the application shaft 8. It becomes the shaft part 14.

  In FIG. 3, the comb piece 6 is formed of a plastic molded product integrally provided with a bullet-shaped connecting boss 16 and three comb teeth 17 protruding from the outer surface of the connecting boss 16. A comb base portion 18 having a mountain-shaped cross section is formed in a tapered shape at the protruding end of the connecting boss 16, and three triangular comb teeth 17 having sharp tips on the outer surface of the comb base portion 18 protrude vertically. It is set up. As shown in FIG. 1, the comb teeth 17 protrude in a state parallel to the central axis of the core shaft 11.

  A welding hole 19 for heat-welding the previous coupling shaft portion 13 is formed in the coupling end of the coupling boss 16 so as to be recessed. Further, the peripheral edge of the connection end of the connection boss 16 is rounded in a circular shape to form a flank 20. By providing the flank 20, when the brush body 5 is pulled out of the mascara liquid container 1, the connecting boss 16 is prevented from being caught by the ironing member 3, and the mascara brush can be smoothly inserted and removed. In addition, when the comb piece 6 passes the entrance / exit opening 3a of the ironing member 3, the connection boss | hub 16 contacted with the entrance / exit opening 3a, and adhered to the periphery of the connection boss | hub 16 when the comb piece 6 passed the entrance / exit opening 3a. The mascara liquid is sized to be scraped off by the ironing member 3.

  The comb piece 6 is connected and fixed to the brush body 5 by heat welding. Specifically, the connection shaft portion 13 of the core shaft 11 is energized, the connection shaft portion 13 is mainly heated locally, and the connection shaft portion 13 is inserted into the welding hole 19 to melt the bottom wall and the surrounding wall of the welding hole 19. The comb piece 6 is fixed to the brush body 5 by solidifying the melted portion. At this time, the insertion depth of the connecting shaft portion 13 is larger than the hole depth of the welding hole 19, and enters the welding hole 19 in a state where a part of the bristle 12 adjacent to the connecting shaft portion 13 is melted. Promotes welding fixation. Further, since the brush bristles 12 that are thermally deformed or melted when the connecting shaft portion 13 is heated are pushed into the welding holes 19, the exposed bristles 12 that are thermally deformed are prevented from being exposed to the outer surface. It is possible to reliably prevent the appearance of this from being damaged. The obtained brush body 5 is welded and fixed by being inserted into an attachment hole 8 a provided in the application shaft 8 in a state where the end portion of the attachment shaft portion 14 is similarly heated. FIG. 4 is a six-sided view showing the appearance of the brush body 5 and the comb piece 6.

  The mascara brush comprised as mentioned above can apply | coat the mascara liquid hold | maintained between the brush hair 12 to an eyelash effectively by scrubbing an eyelash with the brush hair 12. FIG. In addition, the holder 4 is held vertically with the brush body 5 facing upward, and the eyelashes are pushed up with the comb teeth 17 of the comb piece 6 at the upper end to prepare the mascara liquid applied to the eyelashes. While removing, the eyelashes can be evenly combed and finished in a natural state. At this time, the comb base portion 18 formed in a cross-sectional mountain shape can quickly flow down or drop the mascara liquid scraped off by the comb teeth 17 or the solidified mascara along the slope of the comb base portion 18, It is possible to prevent the mascara liquid from accumulating at the proximal ends of the comb teeth 17.

  Moreover, since the comb pieces 6 smaller than the spiral diameter of the bristles 12 are used to wash away the eyelashes several times, the eyelashes can be prepared while clearly viewing the state of the eyelashes without being disturbed by the comb pieces 6. Further, it is possible to prevent the eyelashes that have already been combed out from being unnecessarily combed by the comb teeth 17. Therefore, the finish of the eyelash after applying the mascara liquid can be performed more accurately and easily than the conventional mascara brush in which the eyelashes are scattered with a comb provided on one side of the peripheral surface of the brush body.

  The comb piece 6 of the present invention can be implemented in the manner shown in FIGS. 5 and 6. The comb piece 6 shown in FIG. 5A has basically the same structure as the comb piece 6 described in FIGS. 1 to 4, but the number of comb teeth 17 protruding from the comb base 18 is four. As described above, the spacing between adjacent comb teeth 17 is narrowed, and the effect of removing excess mascara liquid by the comb teeth 17 is improved.

  In the comb piece 6 shown in FIG. 5B, the front and rear surfaces 17a and 17b of the comb teeth 17 are formed as curved surfaces, and the comb teeth 17 are formed in a claw shape. Further, in the comb piece 6 shown in FIG. 5C, the front and rear surfaces 17a and 17b of the comb teeth 17 are formed as corrugated surfaces, and the comb teeth 17 are formed in a claw shape. In this way, according to the comb piece 6 in which the comb teeth 17 are formed in a claw-like shape, the eyelashes can be combed while the tip ends of the comb teeth 17 are biased forward or backward, so that the eyelashes can be removed at the tip ends of the comb teeth 17. It can be arranged more delicately.

  In the comb piece 6 shown in FIG. 6A, the connecting boss 16 and the comb teeth 17 are configured as separate parts, and the comb teeth 17 are welded and fixed to a mounting recess 22 formed in the connecting boss 16. The comb teeth 17 in this case can be formed of a plastic molded product or a metal processed product.

  The comb piece 6 shown in FIG. 6B has a comb shaft 23 projecting from the end of the connecting boss 16, and five comb teeth 17 projecting in parallel on one side of the comb shaft 23. In this case, the comb teeth 17 project laterally in a state orthogonal to the central axis of the core shaft 11.

  Other than the above embodiment, the flank 20 does not need to be formed by rounding the periphery of the connecting boss 16 and can be formed by a tapered surface. The comb portion 18 does not have to have a mountain shape in cross section, and may have a tapered shape in which only one of the front and rear surfaces is inclined. The comb piece 6 can be configured by insert-fixing the comb teeth 17 formed of a metal plate to the connection boss 16.
