The application section 14 is formed in a comb-teeth shape in which a plurality of comb bodies 14a protruding in the radial direction from the base 14b are arranged.
The main body 16a is fitted into the cap 20 and integrated.

[Applicator 14]
The application part 14 has an arcuate shape in which the pedestal 14b has an arc that is gently bent, and the bend easily corresponds to the eyes to apply a coating liquid such as mascara. A plurality of columnar comb bodies 14a are arranged in a comb-teeth shape in the application section 14 and protrude in the radial direction (upward and downward) from the pedestal 14b. Yes.
In addition, the arrangement of the comb bodies 14a of the application unit 14 is not limited to the outer side depicting the arc of the application unit 14, but the comb body 14a is provided on the inner side (specifically, as shown in FIG. 6B). The comb body 14a is provided above and below the pedestal 14b to make it easy to apply finely to the hair. The arrangement length of the upper and lower comb bodies 14a of the application unit 14 may be provided in the middle or in the whole.

  Moreover, although the comb body 14a is thin and short corresponding to the eyelashes, it can be set to an appropriate length. The comb body 14a may be made of the same material as the pedestal 14b or a resin material made of a different material. Moreover, the bulging part 14c is provided in the front-end | tip of the comb body 14a as follows.

As shown in FIG. 6 (a) (also shown in FIG. 5 (c)), in the application part 14, each comb body 14a has a diameter larger than that of the comb body 14a (center part or base part) at the tip thereof. The bulging portion 14c is formed.
The bulging portion 14c is formed in a columnar shape having a circular or elliptical cross section. Since the bulging portions 14c are formed in the comb body 14a, the spacing between the bulging portions 14c is narrower than the spacing between the comb bodies 14a. According to this structure, when hair (lashes, hair, etc.) comes out from between the comb bodies 14a, the hair passes between the narrow bulge portions 14c, and the bulge portions 14c can easily touch the hair. The liquid can be efficiently applied to the hair.

  Further, as shown in FIG. 6B, the comb body 14a of the application unit 14 protrudes from the pedestal 14b, but the cross section thereof is preferably a polygonal cross-sectional shape or an elliptical cross-sectional shape. Thus, when the comb body 14a has a polygonal cross-sectional shape or an elliptical cross-section, the bending strength of the comb body 14a is increased and it is difficult to bend, thereby preventing the coating portion 14 from being damaged during ironing or use. It becomes possible.

  The comb body 14a of the application unit 14 can be set so that the comb thickness or the comb interval is different for each place (or a plurality of places). As shown in FIG. 6C, for the comb body 14a, the comb thickness t1, t2, t3... (Including the bulging portion 14c) or the comb interval w1 (of the interval between adjacent bulging portions). , W2, w3... Can be formed individually and arbitrarily differently. Thereby, the application part 14 can set the comb thickness and the comb interval that are easy to apply in accordance with the characteristics of the aligned hairs such as eyelashes.

  Further, as shown in FIG. 6 (d), the application unit 14 can be formed by protruding comb bodies 14a (14a1, 14a2) on and under the base 14b. In this case, it is preferable to have a structure in which many comb bodies 14a1 are arranged on the upper side of the pedestal 16b and few comb bodies 14a2 are arranged on the lower side. By adopting this structure, the upper comb body 14a (14a1) is used when applying the liquid to the whole of the aligned hairs, and the lower comb body 14a ( By using 14a2), efficient and fine coating can be performed. The number and position of the upper comb body 14a (14a1) and the number and position of the lower comb body 14a (14a2) are not limited to increasing the upper side as described above, but the upper side may be partially It is possible to increase the lower side.

The application part 14 has two or more comb bodies 14a (14a3) protruding at the tip thereof in the axial direction of the pedestal 14b (indicated by reference numeral “F” in FIG. 6D). Is preferred. The tip comb body 14a (14a3) can be easily positioned at the target location and can be applied easily when painting partially or narrowly. The comb body 14a (14a3) at the tip can be provided with a bulging portion 14C.
In addition, in the said application part 14, although all the bulging parts 14c were provided in the comb body 14a, the bulging part 14c can also be provided partially.

  As shown in FIG. 1, the applicator is provided with a cylindrical cap 20 that is detachably closed at the front, and an external screw on the outer periphery of the cylindrical portion 12 b of the outer shaft 12 is connected to a female on the inner periphery of the rear portion of the cap 20. The screw is structured to be screwed together. This screwing allows the cap 20 to be freely attached to and detached from the applicator. Further, the shaft body 16 is fitted into the cap 20, and the shaft body 16 is also detached from the outer shaft 12 when the cap 20 is removed.

  In the applicator, the inner shaft 10 is formed with an inside of the rear end portion 10a in an R shape in which the coating solution is accommodated and the coating solution can be easily attached to the coating portion. With this R shape, the shaft body 16 can be rotated or tilted by operating the shaft body 16 via the cap 20, so that the coating liquid can be sufficiently attached to the coating portion 14.

  As described above, in the embodiment, the inner shaft 10 and the outer shaft 12 can be easily made into two parts by injection molding instead of a blow bottle, and it is possible to easily produce a storage container. By forming the shaft, it is possible to achieve an excellent effect that it is possible to improve the designability of the exterior part and improve the molding productivity.

  Further, since an injection molding manufacturing method can be employed, it is possible to easily provide a fitting portion such as an undercut at the mouth on the inner diameter side of the outer shaft 12.

  Therefore, it is easy in design to maintain the fitting strength of the seal member 18, and since it is not a blow container, there is no problem that the shape is not complicated and the residual liquid is increased when the design is given. .

In addition, the sealing member 18 can be easily provided with fitting portions such as the ribs 18b, and the strength can be imparted without complicating the shape and reliably preventing an increase in cost.
In addition, assemblability and formability are improved.

  In addition, in embodiment, although the applicator which accommodated coating liquids, such as mascara, in the inner shaft 10, was illustrated, this invention is not limited to this, cosmetics, such as nails other than mascara, eyeshadow, or other than that A coating solution can be used.

  The applicator of the present invention can be used for applicators of various coating liquids in addition to cosmetic container products that apply cosmetics such as mascara.
