  However, in the above prior art, the discharge port is provided at a position retracted backward from the tip of the application body, and care is taken so that the liquid discharged from the discharge port can be extended using the flexibility of the flat portion. However, since the liquid discharged to the flat surface portion is sandwiched between the skin and the skin, it will protrude from the intended application area. For this reason, the liquid becomes ball-shaped and it is difficult to apply the liquid to the skin surface with a uniform film thickness. For example, if the liquid is like a double glue (double adhesive) that is applied on the eyelids, it would be difficult to form a liquid film well if the double line is overcoated. There was a problem.

  The present invention has been made in order to solve the above-described problems of the prior art, and when applying cosmetics to the skin, avoiding the use of cosmetics and preventing waste of cosmetics. Another object of the present invention is to provide a cosmetic applicator that can be comfortably applied to the skin in a band-like manner with a brush-like sensation.

A cosmetic applicator characterized in that a guide channel having a substantially concave cross section in a plane substantially perpendicular to the central axis is formed up to the tip of the applicator.

According to the present invention, by forming a pair of inclined surfaces inclined in a tapered manner on both the upper and lower sides of the application body, the vicinity of the application body is elastically deformed flexibly, and the application body has a concave cross section. Since the guide channel is formed, the cosmetic can flow while being guided without overflowing in the downstream direction, in other words, in the tip direction.
For this reason, when the cosmetic from the cosmetic supply means is supplied to the tunnel-like flow path of the application body, it is discharged to the opening edge as the cosmetic discharge port. By sliding the guide channel that exists downstream from the opening edge, i.e., the cosmetic discharge port, to the skin to be applied, the cosmetic discharged to the opening edge does not overflow from the guide channel, and does not overflow the guide channel. Apply it as if it were a spatula. Thereby, regardless of the amount of the cosmetic discharged from the discharge port, the cosmetic can be applied to the skin while being thinly stretched like a band like a brush.

Therefore, for example, it is suitable for a cosmetic applicator for applying a cosmetic having an adhesive function used for making double eyelids, attaching false eyelashes, preventing drooping of the eyelids, and the like.

According to the present invention, since the R portion is formed at the opening edge, the cosmetic material that has flowed through the tunnel-shaped channel is smoothly discharged to the opening edge without receiving resistance from the opening edge. be able to. Therefore, it is possible to prevent wasteful use of cosmetics.

(5) The present invention is also characterized in that the cross-sectional area of the tunnel-shaped flow path is gradually reduced in a tapered manner without having a step as it goes toward the cosmetic discharge port. The cosmetic applicator according to any one of) to (4).
ADVANTAGE OF THE INVENTION According to this invention, it can discharge, adjusting finely the discharge amount of the cosmetics discharged from a cosmetics discharge port, and the consumption of cosmetics can be suppressed now.

(6) The cosmetic according to (5), wherein a cross section of the tunnel-shaped flow path including the pair of inclined surfaces is formed in an elliptical shape among the tunnel-shaped flow paths. It is an applicator.
According to the present invention, since the cross section of the tunnel-shaped flow path having a pair of upper and lower inclined surfaces is formed in an elliptical shape, the application body having the pair of upper and lower inclined surfaces has a supple flexibility and a brush-like feel. Application performance will be brought about. In addition, since the application body sandwiched between the pair of upper and lower inclined surfaces can be made into a form of a cosmetic applicator that is even more flat and sharp, application performance can be improved.

(7) The present invention is also characterized in that the pair of left and right side surfaces of the pair of upper and lower inclined surfaces are formed so as to approach each other in a tapered manner toward the tip of the guide channel. The cosmetic applicator according to (2) .
According to the present invention, at least the shape near the tip of the cosmetic applicator where the guide channel exists has a substantially quadrangular pyramid shape with a pair of upper and lower inclined surfaces and a pair of left and right side surfaces. The delicate and delicate coating performance required for preventing eyelids, false eyelashes, and eyelid dripping can be exhibited.

  According to the present invention, since the cosmetic discharged to the cosmetic discharge port, that is, the opening edge flows downstream along the guide flow path, the cosmetic is applied to the skin with a uniform thin film thickness in a band-like manner like a brush. Can be spread and applied. Therefore, for example, it is possible to obtain a cosmetic applicator that is convenient for applying a cosmetic having an adhesive function used for making double eyelids, attaching false eyelashes, or preventing the eyelids from hanging down.

  Hereinafter, a cosmetic applicator according to an embodiment of the present invention will be described with reference to FIGS. In the present embodiment, a cosmetic applicator applied to form a “double eyelid” will be described as an example. In FIG. 1, the schematic configuration of a cosmetic applicator 1 according to the present embodiment will be described. The cosmetic applicator 1 includes a cylindrical main body 2, an applicator 3 having elasticity that is fitted into the main body 2, and a main body 2. And a cap 4 that is detachably attached to the head. The main body 2 incorporates cosmetic supply means that can supply cosmetics by pressurizing a cosmetic (not shown) that is known per se described in Patent Document 1, for example. A cosmetic material having an adhesive function is supplied to the application body 3. Note that the cosmetic supply means may be configured such that only a certain amount of cosmetic can be discharged by a single knock operation using a known knock mechanism. Further, the cosmetic refers to what is applied to the “eyelid” in order to make a “double eyelid”, and its components are those known per se that are commercially available.

When the outline of the single application body 3 is shown by an illustration drawn with graphic software, it has a structure exhibiting an external form as shown in FIGS. The application body 3 is formed of a transparent or translucent material, in other words, an elastic resin material such as rubber or elastomer, and has an application performance that allows cosmetics to be applied to the skin as if writing brush.
Hereinafter, the application body 3 will be described more specifically. As shown in FIG. 5 (a), a tunnel-like flow path 5 for cosmetic flow that penetrates along the longitudinal central axis L is formed inside the application body 3, and the right end thereof is not shown in the cosmetic supply means. Communicating with
As shown in FIG. 6C, the tunnel-like flow path 5 is formed in a circular cross-sectional shape in the substantially right half of the application body 3, and in a portion extending between the pair of upper and lower inclined surfaces 6 and 7 in the substantially left half. As shown in FIG. 6B, an elliptical cross-sectional shape is formed.

On the other hand, a pair of inclined surfaces 6 and 7 are formed on both the upper and lower sides of the application body 3 so as to be tapered toward each other in the downstream direction of the tunnel-like flow path 5 (left direction in FIG. 5A). That is, an inclined surface in which one of the inclined surfaces 6 and 7 is referred to as the first inclined surface 6 and the other inclined surface is referred to as the second inclined surface 7 is formed.
On the other hand, an opening edge 8 is formed in the vicinity of the tip of the first inclined surface 6 (near the downstream end) as a cosmetic discharge port that cuts out the upstream side from the downstream end and communicates with the tunnel-shaped flow path 5. A guide channel 9 having a concave cross section in a plane substantially perpendicular to the longitudinal center axis L (see FIG. 5A) is formed on the downstream side of the opening edge 8. Specifically, the guide channel 9 is formed by the first inclined surface 6 and a pair of left and right side surfaces 10 and 11 of the pair of upper and lower inclined surfaces 6 and 7. That is, the first inclined surface 6 forms the bottom of the guide channel 9, the pair of left and right side surfaces form the side walls thereof, and the guide channel 9 having a concave cross section as a whole is formed.

The opening edge 8 serving as a cosmetic discharge port is formed so that the opening width becomes wider toward the downstream of the guide channel 9. In the present embodiment, a U-shaped or V-shaped form is presented. In the vicinity of the downstream end (tip) of the opening edge 8, it substantially coincides with the inner wall of the tunnel-shaped flow path 4.

In addition, a curved R portion 12 is formed along the opening edge 8 at a portion of the opening edge 8 that wraps around the tunnel-shaped flow path 5 so that viscous cosmetics can be smoothly discharged without resistance.
The tunnel-like flow path 5 gradually decreases its cross-sectional area in a tapered manner without having a step as it goes toward the cosmetic discharge port, that is, the opening edge 8. As a result, the cosmetic is squeezed and can be reliably supplied to the cosmetic discharge port 8. Further, in the present embodiment, as shown in FIG. 6B, the tunnel-like flow path 5 in a portion where the first and second inclined surfaces 6 and 7 exist is formed in an elliptical cross section. The applicator 3 on the first and second inclined surfaces 6 and 7 has a slightly flat appearance, so that the applicator 3 can have a brush-like feel with flexible flexibility.

The both side surfaces 10 and 11 of the left and right pair at the tip of the application body 3 are formed in a tapered shape so as to approach each other toward the tip of the guide channel 59. Thereby, the application body 3 around the guide channel 59 has a more supple feeling like a brush, and it is easy to create a double eyelid.

Since the present embodiment has the above-described configuration, when the cap 4 is removed from the main body 2 of FIG. 1 to make a “double eyelid”, the cosmetic supplied from the cosmetic supply means (not shown) to the cosmetic discharge port 13 is applied to the “eyelid”. At this time, as shown in FIG. 5A, the cosmetic 13 is discharged into the back of the opening edge 8 on the second inclined surface 7 side. Next, the cosmetic 13 as a “double glue” (double adhesive) is made with the width of the guide channel 9 along a line that forms a double with the second inclined surface 7 facing the “eyelid” side. Apply in strips. Thereby, it can apply | coat to a film form, without cosmetics becoming a ball | bowl on a double line. By forming a double using a stick (not shown), it becomes a perfect pupil.

As described above, according to the present embodiment, when the cosmetic 13 is applied to the eyelid, the cosmetic 13 can be accurately applied in a band shape without protruding from the guide channel 9, so that the cosmetic becomes a ball. It can be avoided, and as a result, cosmetics can be saved. Further, the overall appearance of the application body 3 is formed in an elliptical shape or a flat shape, and the cross section of the tunnel-shaped flow path 5 between the first and second inclined surfaces 6 and 7 is formed in an elliptical shape. Therefore, the cosmetic applicator 1 with a rich brushstroke sensation that increases the flexibility of the application body 3 can be realized.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea thereof.
In the above embodiment, the cosmetic applicator 1 that forms a double eyelid has been described, but in addition to this, a cosmetic applicator for “false eyelashes”, a cosmetic applicator that lifts the hanging of the eyelids, and “stain hiding” It can also be applied to cosmetic applicators.

Further, as shown in FIGS. 7A and 7B, it is also possible to extend the tongue portion 14 at the tip edge of the first inclined surface 6 and provide it integrally. According to such a configuration, the cosmetic can be more effectively stretched and applied to the skin using the flexibility of the tongue-like extension portion 14.
In the above description, the innermost portion of the opening edge 8 is curved. However, as shown by reference numeral 15, a linear opening edge may be formed.

INDUSTRIAL APPLICABILITY The present invention is used for a cosmetic applicator used for making double eyelids, attaching false eyelashes, or preventing eyelids from drooping.
