Interdental Brush

Abstract

An interdental brush includes a handle, an elongate bar mounted on a first end of the handle and having a surface provided with a plurality of bristles and a pointed shank mounted on a second end of the handle and having a surface provided with a plurality of serrated portions. Each of the bristles is provided with at least one intersection which divides each of the bristles to form a protrusion. The intersection of each of the bristles can expand a clearing extent during a reciprocal movement of the elongate bar to catch and carry away residuals left in a gap between a user's any two teeth exactly and completely.

1 . An interdental brush, comprising:
 a handle;   an elongate bar mounted on a first end of the handle and having a surface provided with a plurality of bristles;   wherein each of the bristles is provided with at least one intersection which divides each of the bristles to form a protrusion;   the intersection of each of the bristles can expand a clearing extent during a reciprocal movement of the elongate bar to catch and carry away residuals left in a gap between a user's any two teeth exactly and completely.   
     
     
         2 . The interdental brush of  claim 1 , wherein the interdental brush is integrally formed by a soft plastic material. 
     
     
         3 . The interdental brush of  claim 1 , further comprising:
 a pointed shank mounted on a second end of the handle;   wherein the pointed shank has a reduced size and has a surface provided with a plurality of serrated portions.   
     
     
         4 . The interdental brush of  claim 1 , wherein
 the bristles have different lengths;   the lengths of the bristles are reduced gradually from a middle position of the elongate bar toward two opposite ends of the elongate bar.   
     
     
         5 . The interdental brush of  claim 1 , wherein the elongate bar has a free end provided with a circular head. 
     
     
         6 . The interdental brush of  claim 1 , wherein the intersection of each of the bristles is perpendicular to each of the bristles. 
     
     
         7 . The interdental brush of  claim 1 , wherein the intersection of each of the bristles has a substantially V-shaped profile and has two opposite sides each inclined relative to each of the bristles. 
     
     
         8 . The interdental brush of  claim 1 , wherein the elongate bar has a peripheral wall provided with a plurality of flanges. 
     
     
         9 . The interdental brush of  claim 1 , wherein
 the at least one intersection of each of the bristles is located at a free end of each of the bristles;   the at least one intersection of each of the bristles protrudes outwardly from two opposite sides of the free end of each of the bristles.   
     
     
         10 . The interdental brush of  claim 1 , wherein each of the bristles is provided with a plurality of intersections which are arranged in a staggered manner.
