Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a brush for lipstick application and other cosmetic brushes.

(Prior Art) FIGS. 14 and 15 show a conventional makeup brush, in which a brush body 4 having a tip 3 is attached to a cylindrical housing body 1 via a fitting 2 so as to be freely movable in the axial direction. A coil spring 5 that urges the brush main body 4 in the backward direction is stored, and when the cap 6 is fitted into the storage cylinder 1 from the proximal end, the cap 6
By inserting the extrusion body 7 into the housing cylinder 1 from the proximal opening 1a and extruding the brush body 4 against the coil spring 5, the tip 3 and the attachment 2 are removed, as shown in FIG. The distal end side is configured to protrude from the distal end side opening 1b of the storage cylinder 1.

However, in the above case, the brush main body 4, which is housed and held in the cylindrical storage tube 1 so as to be freely movable in the axial direction, is rotatable around the axis relative to the storage tube 1, and as shown in FIG. When using the makeup brush with the makeup brush 3 protruding outward, the brush body 4 unexpectedly rotates around its axis with respect to the storage cylinder 1, which makes it difficult to apply makeup using the makeup brush configured as described above. There was a fear that things would become difficult.

Therefore, in order to prevent the brush body 4 from rotating unexpectedly with respect to the housing cylinder 1 and to make it easier to use the makeup brush, for example,
Cosmetic brushes such as those disclosed in Publication No. 113113 and Japanese Utility Model Application Publication No. 54-47579, that is, as shown in Fig. 16,
A guide tube 8 is fixed inside the storage cylinder 1 (storage shaft cylinder),
A polygonal inner surface 9 is formed on the inner peripheral surface of the guide tube 8, and a brush body 4 (support rod) having a tip 3 (brush) is formed.
The peripheral surface of the brush body 4 may also be formed into a polygonal surface 10 that matches the polygonal inner surface 9 of the guide tube 8 (see Japanese Utility Model Application Publication No. 113113/1983), or as shown in FIG.
The tip 4a of the (holder) is formed into a wedge portion 4b, and the tip 1b of the storage cylinder 1 (cylindrical handle rod)
is indented inward to form an inclined wall surface 1c that can match the wedge portion 4b, and with the tip 3 (bristle) protruding from the tip 1b of the storage cylinder 1,
A structure in which the wedge portion 4b is in contact with the inclined wall surface 4c (see Japanese Utility Model Application No. 54-47579).
has been devised.

(Problem to be Solved by the Invention) However, in the cosmetic brush of Utility Model Application Publication No. 55-113113, the peripheral surface of the brush body 4 having the tip 3 is formed into a polygonal shape that matches the polygonal inner surface 9 of the guide tube 8. Since the brush body 4 has a surface 10, it is necessary to rotate and align the brush body 4 with respect to the guide tube 8 during assembly work, which is very troublesome.

In addition, the cosmetic brush with the above structure requires the guide tube 2 between the housing cylinder 1 and the brush body 4, and the circumferential surfaces of the guide tube 2 and the brush body 5 are adapted to each other as described above. It must be a polygonal surface, so
It is also quite expensive.

Further, in the makeup brush of the Japanese Utility Model Publication No. 54-475793, as described above, the tip 4a of the brush body 4 must be formed into the wedge portion 4b, and the tip 1b of the storage cylinder 1 is formed into the wedge portion 4b. Since the sloped wall surface 1c must be made to match the part 4b, the cost is high, and when assembling these parts, the brush body 4 must be rotated relative to the housing cylinder 1 to align it. It is very troublesome.

Furthermore, since the shape of the tip 3 is flat in accordance with the shape of the tip 1b of the storage cylinder 1, the tip of the bristles spreads out and is difficult to use when actually used.

In view of the above-mentioned problems, the present invention prevents the brush body from unexpectedly rotating with respect to the storage cylinder, and allows the makeup brush to be used easily and favorably.
To provide a makeup brush that can be manufactured very easily and at low cost.
