Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a mascara brush for applying a mascara liquid to eyelashes.

[Prior Art] As shown in FIG. 2, a conventional mascara brush has a desired amount of brush bristles 11 appropriately cut between two wires 10a, 10b.
By twisting the wire 10 while sandwiching the
It was common to fix the brush bristles 11 in a spiral shape. Therefore, as shown schematically in FIG. 3, the brush bristles 11a at a predetermined position A between the wires 10a and 10b and the bristles 11b at a position B rotated once from this position stand up with a high density. A gap 1 approximately corresponding to the thickness of the wire 10a or 10b is formed between the brush bristles 11a and 11b. Therefore, since the mascara liquid cannot be held uniformly, there is a problem that when the eyelashes are applied to the eyelashes, lumps are partially formed, resulting in poor makeup finish and quick makeup loss.

As a conventional attempt to overcome such a drawback, as the brush bristles 11, a cross-section having an irregular shape other than a circular shape or a hollow bristle is used, and as shown in FIG.
When the brush bristles 11 are sandwiched between a and 10b, the pressure causes the wires 10a and 1
There is one in which the bristles of the bristles 11 between 0b are spread so as to be dispersed, and the bristles density is made uniform as a whole.

[Problems to be solved by the invention] However, not only is the cost of the conventional bristles for mascara using such irregular or hollow bristles high, but also the defect rate in the leg opening process of the bristles. Therefore, there is a problem that the manufacturing cost is increased.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a mascara brush that has uniform bristles and can hold a mascara liquid uniformly, and that has a low manufacturing cost.

[Means for Solving the Problems] In order to achieve the above object, a brush for mascara according to the present invention electrostatically implants a large number of brush bristles on the surface of an elongated shaft member, and is insoluble in the entire portion where the electrostatic bristles are implanted. Apply resin coating.

[Operation] Since the brush bristles are electrostatically flocked, a uniform brush bristle density is obtained, the amount of the mascara liquid retained is made uniform over the entire brush, and an appropriate amount of mascara liquid can be applied uniformly. Since the coating with the insoluble resin is applied to the entire portion where the electrostatic flocking is performed, the swelling or elution of the adhesive can be prevented.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a vertical cross-sectional view of a mascara brush according to an embodiment of the present invention, showing a mode in which it is integrally attached to a lid of a mascara liquid container.

The shaft member 1 is fixed to the lid 2 of the mascara liquid container at one end and has a small diameter portion 1a at the other end. The surface of the small diameter portion 1a is covered with an adhesive layer 3, and a large number of brush bristles 4, 4 are electrostatically planted on the adhesive layer 3.

The electrostatic flocking may be performed by a conventionally known method, for example, a large number of brushes in which the small diameter portion 1a of the shaft member 1 is coated with an adhesive and only the small diameter portion 1a is inserted into the sealed space to be charged in this space. Blow 4 hairs. Since the brush bristles 4 are charged with the same electric charge, they repel each other, and in a standing state, their ends contact the adhesive and adhere onto the small diameter portion 1a, and are fixed by curing the adhesive. . After that, an insoluble resin is coated on the entire electrostatic flocked portion by means such as spraying.

Since the brush bristles 4 are fixed at predetermined intervals according to the charging voltage, a uniform brush bristle density is obtained, and since they are coated with an insoluble resin, they are not corroded by the cosmetic solvent.

The distance between the brush bristles 4, 4, that is, the brush bristle density, and the length and thickness of each brush bristles can be appropriately selected.

In addition, the present invention can be applied to a conventional wire-fixed brush to electrostatically implant hair in the gap between the brush bristles 11a and 11b to eliminate unevenness in the brush bristles.

[Effect of the Invention] As described above, according to the present invention, since the brush bristles are planted by electrostatic flocking, a uniform brush bristling density can be easily obtained, and the mascara liquid retention amount can be made uniform. Can be achieved. Moreover, since the defective rate in the brush bristle planting step is close to zero, the manufacturing cost can be significantly reduced. Furthermore, the brush bristle density can be easily adjusted, and the length and thickness of the brush bristle can be freely changed.

Also, by coating the entire electrostatic flocked portion with an insoluble resin, swelling and elution of the adhesive can be prevented.
