  By the way, in a flat type makeup brush, a base is arranged at the root part of the hair bundle, and the base is flattened by caulking the base (stripping or tightening a metal joint part). They are gathered and molded.

  However, when a base is used, it is necessary to perform a caulking operation for collecting and forming the hair bundle in a flat shape, and since a deformable material such as metal must be used as the base, the design is limited. It is difficult to improve design properties.

  The present invention solves the above-described conventional problems, and provides a cosmetic brush that can collect and shape a hair bundle in a flat shape without using a mouthpiece, and can easily improve the design. .

  In order to solve the above problems, a cosmetic brush according to the present invention is a cosmetic brush having a brush body and a handle having a flat insertion hole into which the brush body is inserted, the insertion hole being a rear end. It has a tapered shape with a diameter decreasing from the side toward the tip side.

  Preferably, the insertion hole has a reduced diameter in the width direction.

  Preferably, the insertion hole is reduced in diameter in the thickness direction.

  More preferably, it has a tail plug shaft comprising a tail plug portion that closes a rear end portion of the handle and a shaft portion that contacts the rear end portion of the brush body.

  The cosmetic brush of the present invention has a brush body and a handle having a flat insertion hole into which the brush body is inserted, and the insertion hole has a taper whose diameter decreases from the rear end side toward the front end side. Is. Therefore, by inserting the brush body into the insertion hole of the handle, the hair bundle of the brush body is gradually gathered inside by the tapered inner surface, and the hair bundle can be formed into a flat shape without using a base. it can.

  Further, since the handle in which the insertion hole is formed does not need to be caulked, there is no need to use a deformable material like a base. Therefore, a material such as a resin can be used freely, and the design is easy to improve.

  Further, when the insertion hole has a reduced diameter in the width direction, the hair bundles of the brush body can be collected in the width direction.

  Moreover, when the insertion hole has a reduced diameter in the thickness direction, the hair bundle of the brush body can be collected in the thickness direction.

  In addition, in the case of having a tail plug shaft consisting of a tail plug portion that closes the rear end portion of the handle and a shaft portion that contacts the rear end portion of the brush body, the rear end portion of the handle is closed to facilitate use. It is possible to prevent the brush body from coming off.

  As described above, according to the present invention, it is possible to provide a makeup brush that can collect and shape a hair bundle in a flat shape without using a base, and can easily improve the design.

It is (A) top view which shows a brush main body, (B) front view, (C) left side view. It is (A) top view, (B) front view, (C) left side view, and (D) right side view showing the handle. It is (A) top view, (B) front view, (C) left side view, and (D) right side view showing the tail plug shaft. It is a figure which shows the assembly procedure of a makeup | decoration brush.

  Next, with reference to FIG. 1 thru | or FIG. 5, the makeup | decoration brush which concerns on embodiment of this invention is demonstrated. 1A is a plan view, FIG. 1B is a front view, and FIG. 1C is a right side view showing a makeup brush 100 according to the present embodiment. 1A is a partially omitted plan view, FIG. 1B is a partially omitted front view, and a portion above the one-dot chain line is a cross-sectional view.

  As shown in FIG. 1, the makeup brush 100 includes a brush body 10, a handle 20, and a tail plug shaft 30. The handle 20 is formed with an insertion hole into which the brush body 10 is inserted, and the tip of the brush body 10 protrudes from the tip of the handle 20. Further, the tail plug shaft 30 closes the rear end portion of the insertion hole of the handle 20 and abuts on the rear end portion of the brush body 10. In the following description, the brush body 10 side is referred to as “front end side” and the tail plug shaft 30 side is referred to as “rear end side”.

  2A is a plan view, FIG. 2B is a front view, and FIG. 2C is a left side view of the brush body 10. The brush body 10 is obtained by planting a hair bundle 11 on a substantially oval base 12. Since the base 12 is substantially elliptical, the hair bundle 11 is generally flat from the front end side to the rear end side. The material of the hair bundle 11 is not particularly limited, such as animal hair or synthetic fiber hair.

  The amount of the hair bundle 11 of the brush body 10 depends on the size of the insertion hole 21 so that the hair tips have an appropriate density when gathered inside by the insertion hole 21 of the handle 20 described later. Set.

  3A is a plan view, FIG. 3B is a front view, FIG. 3C is a left side view, and FIG. 3D is a right side view. 3A is a partially omitted plan view, FIG. 3B is a partially omitted front view, and a portion above the one-dot chain line is a sectional view. The handle 20 has insertion holes 22 and 23 formed from the front end side to the rear end side of a flat cylindrical body 21. The insertion holes 22 and 23 are for inserting the brush body 10, and a step portion 24 is formed at the boundary between the insertion hole 22 and the insertion hole 23. Further, an annular recess 25 is formed in the vicinity of the rear end of the insertion hole 23, and is fitted to a protrusion of the tail plug shaft 30 described later. The material of the handle 20 is not particularly limited, but it is preferable to integrally form the handle 20 with a resin or the like.

  The insertion hole 22 is formed in a tapered shape whose diameter decreases from the rear end side toward the front end side (from the right side to the left side in FIGS. 3A and 3B). As a result, when the brush body 10 is inserted into the insertion hole of the handle 20, the hair bundle 11 of the brush body 10 is gradually gathered inside by the tapered inner surface. The diameter reduction direction is a width direction (= major axis direction) shown in FIG. 3A and a thickness direction (minor axis direction) shown in FIG.

  Here, the reduction rate of the tip portion with respect to the rear end portion of the insertion hole 22 is defined as a “caulking rate”. The caulking rate can be appropriately set, but is preferably 50% to 90% in both the width direction and the thickness direction, and particularly preferably 80% to 85%. Moreover, although the magnitude | size of the insertion hole 22 can also be set suitably, it is preferable that the rear-end part (inlet side) of the insertion hole 22 shall be 2-40 mm.

  Also, the insertion hole 23 may be formed in a tapered shape with a diameter decreasing from the rear end side to the front end side (from the right side to the left side in FIGS. 3A and 3B). It is preferable from the point of easiness. However, since the insertion hole 23 does not finally collect the hair bundle 11 of the brush body 10 inside, it does not necessarily have to be tapered.

  4A is a plan view, FIG. 4B is a front view, FIG. 4C is a left side view, and FIG. 4D is a right side view. The tail plug shaft 30 includes a tail plug portion 31 and a rod-shaped shaft portion 32 extending from the tail plug portion 31 toward the distal end side. The tail plug shaft 30 is inserted into the insertion hole 23 from the rear end portion of the handle 20. The tail plug portion 31 closes the rear end portion of the handle 20, and the shaft portion 32 comes into contact with and presses the rear end portion (base 12) of the brush body 10. Further, an annular convex portion 33 is formed on the rear end side of the tail plug shaft 30 and is fitted to the concave portion 25 of the handle 20 so that the tail plug shaft 30 is fixed to the handle 20. .

  Next, with reference to FIG. 5, the assembly procedure of the cosmetic brush 100 according to the present embodiment will be described. FIG. 5 is a diagram showing an assembling procedure of the makeup brush 100.

  First, as shown in FIG. 5A, the brush body 10 is inserted from the rear end side of the handle 20 to the front end side. At this time, as it is inserted into the insertion hole 22 on the distal end side of the handle 20, the hair bundle 11 of the brush body 10 gradually gathers inside (width direction and thickness direction) due to the tapered inner surface of the insertion hole 22. Then, the pedestal 12 of the brush main body 10 comes into contact with the step 24 in the handle 20 and stops. FIG. 5B is a view of the brush body 10 and the handle 20 after being mounted in the handle 20.

  Next, as shown in FIG. 5 (3), the tail plug shaft 30 is inserted and fixed from the rear end side of the handle 20 to which the brush body 10 is attached. At this time, the convex portion 33 of the tail plug shaft 30 is fitted and fixed to the concave portion 25 of the handle 20. The tail plug portion 31 closes the rear end portion (insertion hole 23) of the handle 20, and the shaft portion 32 contacts and presses the rear end portion (base 12) of the brush body 10. FIG. 5 (4) is a completed assembly view of the makeup brush 100.

  The cosmetic brush 100 according to the present embodiment includes a brush body 10 and a handle 20 having a flat insertion hole 22 into which the brush body 10 is inserted. It has a tapered shape with a diameter decreasing toward the side. Therefore, by inserting the brush body 10 into the insertion hole 22 of the handle 20, the hair bundle 11 of the brush body 10 is gradually gathered inside by the tapered inner surface, and the hair bundle 11 is flattened without using a base. Can be formed into a shape.

  Further, since the handle 20 in which the insertion hole 22 is formed does not need to be caulked, there is no need to use a deformable material such as a base. Therefore, a material such as a resin can be used freely, and the design is easy to improve.

  Moreover, since the insertion hole 22 is diameter-reduced in the width direction, the hair | bristle bundle 11 of the brush main body 10 can be collected in the width direction.

  Moreover, since the insertion hole 22 is diameter-reduced in the thickness direction, the hair | bristle bundle 11 of the brush main body 10 can be collected in the thickness direction.

  Further, since the tail plug shaft 30 is composed of a tail plug portion 31 that closes the rear end portion of the handle 20 and a shaft portion 32 that contacts the rear end portion of the brush body 10, the rear end portion of the handle 20 is closed and used. This makes it easy to prevent the brush body 10 from coming off.

  Thus, according to the makeup brush 100 according to the present embodiment, it is possible to collect the hair bundle in a flat shape without using a mouthpiece, and to easily improve the design.

  The cosmetic brush 100 according to the embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and various other modifications can be made.

  For example, in the above-described embodiment, the diameter reduction direction of the insertion hole is both the width direction (= major axis direction) and the thickness direction (minor axis direction). Good.

  In the above embodiment, the tail plug shaft is used. However, the brush body after insertion may be fixed to the handle by, for example, fitting a base of the brush body to the handle.
