Description

  The present invention relates to a cosmetic brush in which a brush made of a synthetic resin with a tapered tip is bundled into a brush ear, and the brush of the makeup brush has a crimp. , By dividing the waveform height of the crimp by the waveform pitch into a coefficient, and mixing at least two kinds of crimps from the crimp shape specified in the range of the minimum value 0.007 ≦ crimp coefficient ≦ maximum value 0.064 Therefore, the present invention relates to a brush tip that has a good collection of tips at the time of application, soft skin contact, and good cosmetic scratching and discharge properties at the time of application.

  Traditionally, brushes for makeup brushes, lip brushes, lacquer ware, etc. have used animal hairs such as horses, deer, pigs, sharks, foxes, chestnuts, sharks, sheep, etc. In order to adjust the hardness, thickness, etc. of the brush head, the product is produced by changing the type and combination of the above animal hairs. Generally, it is said that the quality of a brush head made only of animal hair having a long brush shape and a delicate surface state and elasticity at the tip is good. Representative examples are eyelashes, wool and eyelashes. However, since animal hair is a natural product, it is difficult to obtain a product with a constant quality, it is difficult to obtain an arbitrary size and shape, and there are problems such as low wear resistance. There is also the problem of higher prices due to a decrease in the yield of straw, straw and straw.

  Thus, synthetic resin brushes are used instead of animal hairs that form brush ears. In order to taper the tip of the synthetic resin to make a synthetic resin brush such as animal hair, a method of bringing a synthetic resin fiber into contact with a treatment solution for dissolving or decomposing has been proposed. (See Patent Document 1 and Patent Document 2)

  By the way, a brush tip using a synthetic resin brush with a tapered tip has a problem that the holding power of the cosmetic is low and a problem that the skin feels hard when applied and the feeling of use is bad. In order to solve this problem, a synthetic fiber such as polyethylene terephthalate is crimped, and the tip is tapered (Patent Document 3) or a wavy shape (crimp). A brush tip made of a synthetic resin brush has been proposed (Patent Document 4).

Japanese Patent Publication No.49-6159 (Claims) Japanese Examined Patent Publication No. 60-30556 (column 3, line 24 to column 4, line 15) JP-A-11-235230 (Claims) Japanese Utility Model Publication No. 62-114781 (claims and drawings)

  However, if the polyethylene terephthalate fiber is crimped and made of a brush tip with a tapered tip, the crimp waveform tends to be spiral and circular, the space becomes too large, and the brush tip is scattered, In addition, crimping by this method is easy to crimp in the middle part of the fiber, but because the fiber escapes at both ends of the fiber, it is difficult to crimp, so the crimp state is different in one fiber. There is also a problem that directivity occurs when applied and the feeling of application is poor. In addition, in the case of a brush made of a large number of synthetic resin brushes each having a different crimp wavelength (pitch), the waveform height is the same except that the crimp wavelength (pitch) is different. In the case of a combination of only the high ones, the space becomes too large, the brush heads are not well organized, and the feeling per skin is also poor. On the contrary, in the case of a combination of only those having a low waveform, the space is too small, and the feeling of use is good, but there is a part that the applicability of the cosmetic is inferior.

  The present invention relates to a cosmetic brush in which a brush made of a synthetic resin with a tapered tip is bundled into a brush ear, and the brush of the makeup brush has a crimp. , By dividing the waveform height of the crimp by the waveform pitch into a coefficient, and mixing at least two kinds of crimps from the crimp shape specified in the range of the minimum value 0.007 ≦ crimp coefficient ≦ maximum value 0.064 The main feature is that it is formed.

In a makeup brush with a brush tip made by bundling synthetic resin brushes with a tapered tip, the brush brush of the makeup brush has a crimp, and the crimp waveform The height divided by the waveform pitch is used as a coefficient, and two or more kinds of hairs are mixed from the crimp shape specified in the range of the minimum value 0.007 ≦ crimp coefficient ≦ maximum value 0.064. As a result, it is possible to provide a brush that has a good collection of brush heads at the time of application, a soft touch per skin, and a good scratching property of the cosmetic and a good discharge property at the time of application.
Incidentally, the cosmetic in the present invention is a powdery powder, and as a specific example thereof, it is most preferably used for a powder for teak, a powder for eye shadow, a powder for eyeliner, or the like.

(B) Top view showing a modification of the tip of the brush head It is the schematic side view which gave coloring to the brush ear of the makeup brush which concerns on this invention.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an example applied to a cosmetic brush according to the present invention. Reference numeral 1 is a makeup brush, which is inserted and fixed to the front shaft 15, and this front shaft 15 is inserted and fixed to the end of the shaft 16 to form the makeup brush 1. . In addition, the brush ears 1 are natural-colored brushes 2 to 6 having crimps with tapered tips, and / or brushes having tips with tapered crimps and individually dyed to a specified color. 9 to 13 are mixed and used to converge in the longitudinal direction, and the rear end is fixed by a method such as heat welding or bonding with an adhesive.

  Synthetic resin materials used for the brushes 2, 3, 4, 5, 6 are polyamide (6,6-nylon, 6-nylon, 12-nylon, 6,10-nylon, 6,12- Nylon, etc.), polyester (polyethylene terephthalate, polybutylene terephthalate, etc.), acrylic (modacryl, etc.) can be used, but the materials of the brushes 2, 3, 4, 5, 6 used are the same, but different May be. For example, if the brush 2 is mixed with a soft polyamide-based material with bending strength (at the time of moisture absorption) and the brush 4 is mixed with a polyester material with a high bending strength (at the time of moisture absorption), the polyamide material becomes the skin. There may be conflicting results, such as a soft touch and a polyester material that improves durability.

  The diameter D of the base of the brushes 2, 3, 4, 5, 6 used for the brush ear 1 varies depending on the production use or size (diameter and length), but the brush tip 1 for makeup according to the present invention. The diameter D of the base part of the brushes 2, 3, 4, 5, 6 is preferably 0.05 mm to 0.08 mm. The reason for this is that if the diameter D of the base of the brush is less than 0.05 mm, rough hair without the taper may be mixed in the taper processing, and the diameter D of the base exceeds 0.08 mm. This is because the skin contact at the time of application becomes hard and the feeling of use deteriorates. The filament diameter D mentioned here refers to the diameter of the portion that is not tapered.

  In order to make the brushes 2, 3, 4, 5, 6 made of the synthetic resin tapered from the tip to the back, a method using a chemical treatment solution is preferable. Specific examples thereof include a combination of a mixture of metacresol and calcium chloride-methanol solution with respect to polyamide and sodium hydroxide with respect to polyester. However, it is not necessarily limited to this method, and other methods such as mechanical taper such as grinder polishing may be employed.

The brush 2 of the brush 1 made of synthetic resin with a tapered tip has crimps, and the coefficient obtained by dividing the waveform height H of the crimp by the waveform pitch P is the coefficient. The minimum value of 0.007 ≦ crimping coefficient ≦ maximum value of 0.064 is used by mixing two or more kinds of crimp shapes, and the purpose of using the brush 1 at the time of application is good, The hit is soft and is used to improve the scratching property of the cosmetic and the discharge property at the time of application. The reason is that if the crimp coefficient is less than 0.007, for example, if the height H of the waveform is large, the pitch P becomes very long, and the crimp waveform is less formed in the brush head 1. Therefore, the space is reduced and the skin contact at the time of application is good, but the cosmetic powder is scraped off and discharged at the time of application. In addition, when the waveform is small, the pitch width is also reduced to some extent, but since the height of the waveform is hardly formed, in this case as well, there is almost no space in the brush head. The scraping of the material and the discharge at the time of application become worse.
On the other hand, when the crimp coefficient exceeds 0.064, for example, when the waveform height H is large, the pitch P becomes long, but the waveform height H becomes too high, and a lot of space is formed. The cosmetic scraping and discharging properties are good, but the skin contact at the time of application is poor, and the brush head 1 is broken or cracked. On the contrary, when the waveform height H is low, the pitch P becomes too narrow, and the skin contact at the time of application is deteriorated, and further, the brush ear 1 is broken or cracked. .

The purpose of selecting two or more types of crimp coefficients from the above-mentioned crimp coefficients and mixing them is to mix the hairs with different crimp states, so that a volume and a proper space are formed in the brush head 1, and when applying. The touch becomes soft and is used to improve the scraping and discharging properties of cosmetics. The reason is that when the crimp coefficient becomes one type, for example, when the crimp coefficient is the lower limit (0.007), the crimp condition is low, so the crimp state is formed close to straight, The touch is soft, but the scraping and discharging properties of the cosmetics may deteriorate. In addition, when the crimp coefficient is the upper limit (0.064), the crimped state becomes too large, the feeling of use per skin at the time of application is deteriorated, or the space becomes too large, so that the brush head 1 is scattered. Because it breaks. Here, two or more types of hairs are selected and mixed in the range of the crimp coefficient. However, considering the quality and cost of the finished product, it is most effective to mix the three types.
By the way, two or more kinds of hairs are mixed from the crimp shape specified in the range of the minimum value of the crimp coefficient 0.007 ≦ the crimp coefficient ≦ the maximum value 0.064. Or it is preferable to mix | blend so that one type of hair mixing ratio shall be 20 to 60 weight%, and it may not exceed this range also in four types.

  Further, a crimp shape specified by a coefficient obtained by dividing the waveform height H of the crimp of the brush ear 1 by the waveform pitch P is specified in the range of the minimum value 0.007 ≦ crimp coefficient ≦ maximum value 0.064. Two or more types are selected from the above, but it is preferable that the difference in the crimp coefficient at this time be in the range of 0.015 to 0.055. The reason is that if the difference in the crimp coefficient is less than 0.015, there will be no difference in the crimped state, the space ratio will be too low, and the brush head 1 with volume will not be obtained, and the scraping property and discharge of cosmetics The nature will decline. When the crimp coefficient exceeds 0.055, for example, when two or more groups having a high crimp coefficient are selected, the space ratio becomes too high, and the volume of the brush head 1 is excessively large. It will be broken or cracked.

  Note that the coefficient obtained by dividing the waveform height of the brush crimp by the waveform pitch is a crimp shape specified in the range of the minimum value 0.007 ≦ crimp coefficient ≦ maximum value 0.064 of the coefficient. Two or more types are selected, but as long as there are two or more types, three or four types may be mixed.

  Further, a crimp shape specified by a coefficient obtained by dividing the waveform height H of the crimp of the brush ear 1 by the waveform pitch P is specified in the range of the minimum value 0.007 ≦ crimp coefficient ≦ maximum value 0.064. Two or more types are selected from the above, but if two or more types of brushes with crimps are mixed in, the brush cross-section has an irregular shape, the brush surface has an uneven shape, or the brush cross-section. However, it is possible to mix hair having a hollow shape.

Moreover, the crimp waveform shape of the brushes 2, 3, 4, 5, and 6 used for the brush head 1 has a crimp waveform height H of 0.01 mm to 1.0 mm and a waveform pitch P of 1.0 mm to 8.0 mm. It is preferable to use the thing of the range. The reason for this is that when the crimp waveform height H is less than 0.01 mm, a crimp is hardly formed, and the scraping and discharging properties of the cosmetic may be lowered. On the other hand, when the crimp waveform height H exceeds 1.0 mm, the space ratio becomes too large and the touch becomes rough, and the brush head 1 is broken or broken. If the corrugated pitch P is less than 1.0 mm, although depending on the corrugated height H, the corrugated pitch P is too short, the space ratio becomes too large, and the feeling of use becomes worse. Or crack. Further, if the corrugated pitch P exceeds 8.0 mm, the crimp 1 is hardly formed in the brush tip 1, and the scraping property and the discharge property of the cosmetic are lowered.
The crimp shape is selected from this range, but any number of types may be used as long as it is within this waveform shape range.

  Moreover, although the cross-sectional shape of this brush ear 1 changes with manufacturing uses or a magnitude | size (diameter and length), it is preferable that the cross-sectional shape of a brush ear is circular shape, an ellipse shape, or a rectangular shape. Further, the brush 2 is formed so as to be gradually shortened from the top located at the center of the brush 1 toward the outer periphery, that is, when the longitudinal cross-sectional shape of the front portion of the brush 1 is formed in an arc shape. Further, it is preferable because of its effect.

  In addition, the brush having the crimp used for the brush X is taped to the tips of the brushes 2, 3, 4, 5, 6 and then individually colored with an acid dye, It is preferable to mix hair. The reason is that coloring the brushes 2, 3, 4, 5 and 6 allows the dyes to soak into the brushes, improving the elasticity of the brush head X and also attaching the dyes to the surface of the brushes. Therefore, the release between the brushes 9, 10, 11, 12, and 13 is improved, and the release between the brushes is good. This is preferable because there is an advantage that it can be easily formed into an arc shape.

  In addition, the order of dyeing of brush ear X dyes brushes 2, 3, 4, 5, 6 individually to form brushes 9, 10, 11, 12, 13 and then brushes 9, 10 , 11, 12, and 13 are preferably mixed. The reason for this is that when the brushes 2, 3, 4, 5, and 6 are dyed in a mixed state, spots may appear in the dyed state. Even if there is, a uniform brush head X can be obtained.

  In addition, filaments made of synthetic resin that are colored by kneading a dye into the filament are also sold. In this case, when the taper processing is performed, the dye at the tapered portion is removed, the tip portion becomes a natural color, the colors of the tip portion and the rear portion are different, and the appearance may be deteriorated.

  FIG. 6 shows a second embodiment according to the present invention. In this embodiment, the brush head X is inserted and fixed to the front shaft 15, and the front shaft 15 is inserted and fixed to the line end of the shaft 16 to form the brush tip X. In addition, the brush X has a brush 2 having a crimp with a tapered tip, a brush 3 having a crimp with a tapered tip, and a brush 4 having a crimp with a tapered tip in black tea. The dyed brush, that is, the dyed brushes 9, 10 and 11 mixed at a predetermined ratio are focused in the longitudinal direction, and the rear end portion is fixed by a method such as heat welding or bonding with an adhesive. Formed. In this dyeing method, a black dye, a tea dye and sulfuric acid were stirred while being bathed in water, boiled at 90 ° C. or higher for about 30 minutes, and a brush ear X was formed with a dyed black tea. Is. As for the coloring applied to the brush ear X, the same effect can be obtained no matter what color it is dyed by the above method.

  In manufacturing the cosmetic brush of the present invention, at least two types of the above-mentioned brushes are mixed, and the trailing edge is welded, bonded, or the rear part is tied with a thread to prevent the brush from falling out. As a result, the brush head mixed with hair is arranged such that the brush with the crimp, the brush 3 with the crimp different from the brush 2 and the brush 4 with the crimp are uniformly mixed with each other. It is preferable that
