Description

[Detailed Description of the Invention] The present invention relates to an improvement of a brush for applying or spreading cosmetics.

Conventional brushes made from horse hair hold cosmetics well;
Also, since it comes into smooth contact with the skin surface, it has the advantage of being extremely comfortable to use, but on the other hand, since such brushes only select and compose the sharpened tips of horse hair, the tips of the bristles must be aligned. Production is poor because special techniques are required to produce or quantitatively produce the product, and the insect eggs that adhere to the horse hair must be carefully removed, making it unsuitable for mass production and making the product extremely expensive.

Recently, such brushes have been manufactured using synthetic fibers such as nylon, but these materials have fiber diameters that are the same over the entire length, and the tip of the brush is Since it is cut at right angles to the horizontal direction, there is a disadvantage that it does not allow for cosmetics to be contained, and the cut tip strongly irritates the skin surface, making it difficult to expect a good feeling of use. In order to improve this point, when the tip is sharpened by a machine, a fatal defect as a brush occurs in that the tip of the material stretches more than necessary or clinks and becomes easily entangled with each other. There was a drawback to doing so.

The present invention aims to prevent these conventional drawbacks, provide a brush that retains cosmetics and feels good on the skin like horse hair, and can be industrially produced uniformly and stably.
As shown in the figure, a bundled base part 2 of a raw material 1 made of industrially produced collagen fibers is fixed to a handle 3, and a tip part 4 of the raw material 1 is mechanically pre-applied 5.

In this invention, industrially produced collagen fibers are made by solubilizing collagen that constitutes animal skin, tiles, bones, etc., and making it into fibers using chromium salts, formalin, and methylol derivatives of melamine or urea. After treatment with a sacrificial agent such as horsehair, it is colored in the desired color and its physical properties are substantially the same as horsehair.

In this way, since this product is made from industrially produced collagen fibers, it is highly hydrophilic like horse hair, and even if the tip of the material is machined into a sharp point, it will not be distorted. It does not extend or cliff.

In addition, in this case, after the base of the material made of collagen fibers is fixed to the handle, the tip is mechanically processed, so there is no need to align the ends or measure the amount of hair, which is the case when horse hair is used as the material. While cumbersome processes such as insect and egg extermination are omitted, the quality of the resulting product is extremely stable because it can all be produced industrially.

Therefore, the brush of the present invention has the advantage that it retains cosmetics as well as a brush made of horse hair, and that it comes into smooth contact with the skin surface, resulting in a significantly improved feeling of use, and that it is industrially uniform and stable. Since it can be produced in a variety of ways, it has the effect of being able to provide uniformly high-quality products in large quantities at low prices.
