A cosmetic brush curve with coating function

As a preferred option, the curve C may be approximately circular, and the portion of the brush in the concave portion of the curve C forms a hollow portion. The portion of the brush opposite to the hollow portion forms the brush Because the shape of the cross section of the envelope surface of the brush in the axial direction of the maximum length is slender, the brush of the present invention has two wide flat surfaces in the direction perpendicular to the plane of the core twisting. The wide flat surface is in the hollow part of the brush, and the other wide flat surface is in the back of the brush in the flat surface of the hollow part of the brush. The shape is very similar to the outer contour of the eyelashes. In addition, the flat The face contains short bristles that are not very soft. Therefore, the flat face can be joined with the eyelashes along the entire width of the eyelid. The cosmetics can be used to coat the eyelashes and lengthen and curl the eyelashes due to the gap between the two flat faces. The width of the brush should be smaller than this, and the brush can slide into the corner of the eye very easily, so that the eyelashes can be used for makeup. However, it is not suitable to stain the remaining cosmetics around the corners of the eyes. The side of the brush is very effective for combing and separating the eyelashes. The side has longer and softer bristles than the flat surface, but there is no force. The flat surface is wide and the back of the brush is the same as the hollow part, allowing cosmetics or care products to be spread by engaging the eyelashes on the main part of the length of the eyelashes. Since the back is arched, the brush makes it easier to curl the eyelashes. This very important and prominent feature of the flat surface and the side edges gives the brush an amazing performance: when the user rotates the brush between his fingers, the eyelashes are alternately applied and curled, and then applied Combing with a different intensity than usual. As a preferred option, the core is located at the center of each cross section of the brush. In the first alternative form of the invention, it is stipulated that the section may have at least two sides in the direction of the axis Z-Z of maximum length, and these sides are substantially parallel to the axis Z-Z. In the second alternative form of the present invention, it is stipulated that the section can have at least two sides in the universal direction of the axis Z-Z of the maximum length, and these sides have a convex shape. According to this form of the present invention, it is stipulated that the side of the cross-section has two ends. The width is approximately zero. Regardless of the alternative form of the present invention, it is preferable that the section has at least two sides in the direction of the axis Y-Y, the axis Y-Y is perpendicular to the maximum length axis Z-Z, and the sides have a convex shape. The section may advantageously have a maximum length D in the direction of the axis ZZ of maximum length, and may also advantageously have a maximum width d in the direction of the axis YY, and the maximum length D and the maximum width d satisfy the following relationship : It is better for D and d to satisfy the following relationship, that is, the maximum length D can vary along the core. In order to make the above-mentioned makeup characteristics more prominent, the preferred brush is the kind whose envelope surface has a A brush with an elongated cross-section that is at least 50% of its length and preferably 75% above the length. The brush according to the invention can advantageously be designed in such a way that for each section, the axis of maximum length and the axis of maximum width are perpendicular to each other. In order to make it easier to hold, it is best to specify that each end of the core is aligned with the axis X-X.
