Hair accessory with anti-slip structure and method for making the anti-slip structure on the hair accessory

Abstract

A hair accessory includes a hair accessory body and an anti-slip structure consisting of a plurality of elastic silicon rubber pins or elastic plastic pins and molded on at least one part of the hair accessory body. The formation of the anti-slip structure on the hair accessory is achieved using injection molding technology.

What the invention claimed is: 
     
         1 . A hair accessory, comprising a hair accessory body and an anti-slip structure consisting of a plurality of elastic pins and molded on at least one part of said hair accessory body, said elastic pins being selected from the group of silicon rubber and elastic plastics. 
     
     
         2 . The hair accessory as claimed in  claim 1 , wherein said hair accessory body is a hair band; said elastic pins are evenly distributed over one surface of said hair band. 
     
     
         3 . The hair accessory as claimed in  claim 1 , wherein said hair accessory body is a shrapnel hairpin comprising a center pin having a wave-like pin body and two clamping arms respectively curved from one end of said center pin in direction toward an opposite end of said center pin; said elastic pins are evenly distributed over one surface of each said clamping arm. 
     
     
         4 . The hair accessory as claimed in  claim 1 , wherein said hair accessory body is a hair clip comprising two clamping plates hinged together and loaded with a torsion spring, each said clamping plate comprising a plurality of claws; said elastic pins are evenly distributed over an inner surface of each said claw of each said clamping plate. 
     
     
         5 . The hair accessory as claimed in  claim 1 , wherein each said elastic pin of said hair accessory anti-slip structure has a clawed tip. 
     
     
         6 . A method for forming an anti-slip structure on a hair accessory, comprising the steps of:
 preparing a mold comprising a plurality of cavities defined therein, a plurality of filling holes located in a top side thereof and a plurality of molten material flow passages in communication between said filling holes and said cavities;   putting a blank hair accessory in a bottom side inside said mold;   feeding molten silicon rubber or elastic plastic material through said filling holes of said mold and said molten material flow passages into said elastic silicon rubber pin cavities to mold elastic pins on said hair accessory; and   opening said mold and removing said hair accessory with integrated elastic pins from said mold after cooled down.
