Introduction to the use of a brush for applying cosmetics

by:MHLAN     2021-09-16
Today, our Hongdian makeup brush set is here to introduce a brush for applying cosmetics. Referring to Figures 1 to 4, you can see a brush 1 for applying cosmetics, especially mascara on the eyelashes. The brush includes an elongated brush core 2 formed by spirally winding two metal wires 3, said The metal wire is bent into a U-shape in advance before the double strands are twisted, and the brush core 2 is fixed by forcefully installing it on one end of the handle t. The bristles 4 are radially implanted between the two metal wires 3. When the double-stranded metal wire 3 is twisted, the bristles are firmly fixed and kept positioned between the spiral windings of the brush core 2. The brush core 2 can be set in the center, that is, the axis determined by the brush core 2 coincides with the center axis 1-1 of the brush, as shown in the figure, but the brush core can also be set eccentrically. The bristles 4 may be made of natural or synthetic fibers, and are likely to be aggregated from short fibers; the brush 1 may include a mixture of bristles of different types (different diameters and shapes: cross-sections). The outer surface of the brush is a cylindrical shape with a central axis 1-1. The brush 1 has a flat end 6 perpendicular to the axis 1-1 and a frustum-shaped front end 5 coaxial with the axis II. The diameter of the bottom surface of the front end 5 is the same as the diameter of the cylindrical surface of the brush and is connected to the flat section 10 of the cylinder so as to be perpendicular to the axis II. On the circumferential surface of the brush, there are three recessed cuts 7 defined by an elliptical contour 8. The depth of the contour 8 is d, the length of the long axis is λ, and the maximum width (short axis) is L, and the contour 8 meets λ>L. >d. The profile 8 of the cut has two rounded edges 8a and 8b which are substantially parallel to the axis I-I. The contour of the cut defines part of the convex surface 9 belonging to the cylindrical surface of the brush. In the illustrated embodiment, the contour of the cutout is oblong, but it can also be round (in-L), elliptical, or composed of two intersecting circles whose recesses face each other. The contour 8 of the cut 7 defines the sharp edge 11 constituting the convex surface 9. The cuts 7 are obtained by cutting the brush 1, that is to say by cutting the bristles 4 of the brush with a trimming tool, and each cut 7 is located on the same side of the brush; this will not cut the core 2 transversely. In the figure, the contour 8 of the cut 7 does not extend to the end faces 6, 10 of the cylinder, but in a modified embodiment, the cut can be made tangent or intersected with the aforementioned end face. In Figs. 5 to 7 showing the use method of the brush of the present invention, the components with the same or similar functions as the above-mentioned components are denoted by the same numerals, and the description is not repeated or only briefly discussed herein. Due to simplification, the brushes in these figures have only one cutout, but their function is the same as a brush with multiple cutouts.
