Brush for cosmetic implements and manufacturing method of the same

Abstract

A brush for cosmetic implements includes a brush part attached to a support member; the brush part includes a plurality of synthetic resin fibers whose tip end has a conically tapered surface, and a plurality of fiber bundles composed of a plurality of synthetic resin fibers is formed at least three places in a radial circumferential surface of the support member, and further formed in an axial direction of the support member. Provided is a brush for a cosmetic implements in which a brush bristle having a tapered end is provided around the support member in the radial direction, and a manufacturing method thereof.

         2 . The brush for cosmetic implements according to  claim 1 , wherein the support member is formed of twisted two or more metal wires, and wherein the synthetic resin fiber bundles are held between the wires and fixed to the support member by twisting the metal wires. 
     
     
         3 . The brush for cosmetic implements according to  claim 1 , wherein the fiber bundle is mixedly formed with straight fibers and non-straight fibers. 
     
     
         4 . A brush for cosmetic implements, having a brush part that is attached to a support member,
 wherein the brush part includes a plurality of synthetic resin fibers whose tip end has a conically-tapered surface, and   wherein a plurality of fiber bundles composed of a plurality of synthetic resin fibers is formed on a circumferential surface of the support member as to extend in at least two radial directions and formed on a circumferential surface in an axial direction, and wherein the support member is formed of twisted two or more metal wires and the synthetic resin fiber bundles are held between the wires and fixed to the support member by twisting the metal wires.   
     
     
         5 . The brush for cosmetic implements according to  claim 4 , wherein the plurality of synthetic resin fibers mixedly includes straight fibers and non-straight fibers. 
     
     
         6 . The brush for cosmetic implements according to  claim 1 , wherein the brush part is formed on the whole area of the circumferential surface of the support member. 
     
     
         7 . The brush for cosmetic implements according to  claim 1 , wherein a whole shape of the brush part is formed to be a columnar or a conical shape with a diameter decreasing toward a top portion. 
     
     
         8 . A manufacturing method of the brush for cosmetic implements described in  claim 1 , the method comprising steps of:
 a step in which synthetic resin fibers are bundled and a brush part is formed on the support member, and   a step in which the brush part is immersed in a solution bath containing a soluble liquid; the brush part is brought into contact with a polishing/rubbing blade for a predetermined time to dissolve and swell the surface of the synthetic resin fibers; and the tapered surface is formed by scrubbing off with the polishing/rubbing blade.   
     
     
         9 . The brush for cosmetic implements according to  claim 2 , wherein the fiber bundle is mixedly formed with straight fibers and non-straight fibers. 
     
     
         10 . The brush for cosmetic implements according to  claim 2 , wherein the brush part is formed on the whole area of the circumferential surface of the support member. 
     
     
         11 . The brush for cosmetic implements according to  claim 3 , wherein the brush part is formed on the whole area of the circumferential surface of the support member. 
     
     
         12 . The brush for cosmetic implements according to  claim 4 , wherein the brush part is formed on the whole area of the circumferential surface of the support member. 
     
     
         13 . The brush for cosmetic implements according to  claim 5 , wherein the brush part is formed on the whole area of the circumferential surface of the support member. 
     
     
         14 . The brush for cosmetic implements according to  claim 2 , wherein a whole shape of the brush part is formed to be a columnar or a conical shape with a diameter decreasing toward a top portion. 
     
     
         15 . The brush for cosmetic implements according to  claim 3 , wherein a whole shape of the brush part is formed to be a columnar or a conical shape with a diameter decreasing toward a top portion. 
     
     
         16 . The brush for cosmetic implements according to  claim 4 , wherein a whole shape of the brush part is formed to be a columnar or a conical shape with a diameter decreasing toward a top portion. 
     
     
         17 . The brush for cosmetic implements according to  claim 5 , wherein a whole shape of the brush part is formed to be a columnar or a conical shape with a diameter decreasing toward a top portion. 
     
     
         18 . The brush for cosmetic implements according to  claim 6 , wherein a whole shape of the brush part is formed to be a columnar or a conical shape with a diameter decreasing toward a top portion.
