  Next, manufacture of the liquid applicator 1 of this embodiment is demonstrated based on FIG. In order to manufacture the liquid applicator 1 according to this embodiment, for example, in the final stage of manufacturing the liquid applicator 1, after cutting the tip of the brush bristle material 3 so as to have a predetermined shape, FIG. As shown in FIG. 2, the brush bristle material 3 is bent and its tip 3a is applied to the heating jig 10 and moved in the direction of the arrow.

  As shown in FIG. 9B, the portion of the tip 3a that is in contact with the heating jig 10 is softened and melted by heat, and the melted portion adheres to the heating jig 10 and starts to melt. The melted part is extended by moving. By performing a series of operations in which the tip 3a is softened and melted, and the melted portion is moved while being pulled, the tip 3a of the brush bristle material 3 is melted and formed into a taper 3b by thermal processing. Shape.

  When lengthening the taper 3b of the front-end | tip part 3a, the length of the part applied to the heating jig 10 is lengthened. Also, when trying to make the bristle shape of the brush bristle material 3 fine, the length of the brush bristle material 3 applied to the heating jig 10 should be lengthened. Move while pulling. The tip 3a is removed from the heating jig 10 as shown in FIG. 9C at a position where the necessary length of the taper 3b is secured. Since the brush bristle material 3 is a thin fiber having a diameter of, for example, 0.3 mm to 0.04 mm, precise conditions are required for air cooling inside the heating jig 10 or water cooling from outside the heating jig 10. For example, as the molding conditions, the shape and material of the heating jig 10, the temperature in the heating jig 10, the cooling method, the type and thickness of the brush bristle material 3, the shape of the liquid applicator 1, the amount of hair, and the yarn tension during molding The molding condition and the shape production require various conditions at the moment, so that the tip 3a of the bristle material 3 is melted by thermal processing and is formed into a taper 3b. For example, it can be formed into various shapes as shown in FIG.

  Next, the use of the liquid applicator 1 of this embodiment will be described with reference to FIG.
