Hair Elastic

Abstract

The present invention provides a hair elastic used as a hair band or a hair fastener. The hair elastic includes an endless ring integrally formed by flexible material. The ring includes inner and outer surfaces opposed in a thickness direction. The hair elastic further includes a plurality of minute protrusions uniformly disposed on the inner and outer surfaces of the ring. The plurality of minute protrusions on the inner and outer surfaces is in a point-contact mode with a hair of a user so that the hair elastic is capable of being comfortably fastened to a head of the user and has low resistance during removal.

1 . A hair elastic used as a hair band or a hair fastener, comprising:
 an endless ring integrally formed by a flexible material and having a central hole therein, with the ring including inner and outer surfaces opposed in a thickness direction; and   a plurality of minute protrusions disposed on the inner surface of the ring, allowing a point-contact between the hair elastic and a hair of a user.   
     
     
         2 . The hair elastic according to  claim 1 , further comprising:
 a plurality of minute protrusions disposed on the outer surface of the ring.   
     
     
         3 . The hair elastic according to  claim 2 , with the inner and outer surfaces of the ring having reticulate concave grooves thereon, and with the plurality of minute protrusions on the inner and outer surfaces of the ring defined by the reticulate concave grooves. 
     
     
         4 . The hair elastic according to  claim 3 , with the ring further including two side surfaces spaced in a width direction perpendicular to the thickness direction, and with each of the two side surfaces formed with a plurality of undulating projections along a peripheral direction of the ring. 
     
     
         5 . The hair elastic according to  claim 4 , with the plurality of protrusions on the inner and outer surfaces of the ring having a diameter ranging from 0.005 mm to 0.2 mm and having a height ranging from 0.005 mm to 0.2 mm. 
     
     
         6 . The hair elastic according to  claim 3 , with the plurality of protrusions on the inner and outer surfaces of the ring having a diameter ranging from 0.005 mm to 0.2 mm and having a height ranging from 0.005 mm to 0.2 mm.
