Toothbrush

Abstract

There is provided a toothbrush having an elongate body provided with a handle portion at a first end and a utility portion at a second end opposite to the first end, (a) wherein the utility portion is provided with a platform from which a plurality of tufts of cleaning bristles are extended, (b) wherein the cleaning media is provided with a front region, opposite side regions and a rear region which together forming a circumferential area surrounding a middle region of the cleaning bristles, (c) wherein the tufts of cleaning bristles located at the middle region are formed into at least two peaks configured for insertion into adjacent gaps between successive teeth, (d) wherein the tufts of cleaning media forming the peaks are substantially taller than the tufts of cleaning media along the side regions, and (e) wherein distal end of the two peaks are separated by a distance from 8.15 mm to 9.15 mm.

1 . A toothbrush comprising an elongate body provided with a handle portion at a first end and a utility portion at a second end opposite to said first end;
 (a) wherein said utility portion is provided with a platform from which a plurality of tufts of cleaning media are extended;   (b) wherein said cleaning media is provided with a front region, opposite side regions and a rear region which together forming a circumferential area surrounding a middle region of said cleaning media;   (c) wherein said tufts of cleaning media located at the middle region are formed into at least two peaks configured for insertion into adjacent gaps between successive teeth;   (d) wherein said tufts of cleaning media forming said peaks are substantially taller than said tufts of cleaning media along the side regions; and   (e) wherein distal end of said two peaks are separated by a distance between 8.15 mm and 9.15 mm.   
     
     
         2 . A toothbrush as claimed in  claim 1 , wherein the middle region is provided with three said peaks. 
     
     
         3 . A toothbrush as claimed in  claim 1 , wherein one or more said peaks are conical in shape. 
     
     
         4 . A toothbrush as claimed in  claim 1 , wherein said peaks define an external concave surface. 
     
     
         5 . A toothbrush as claimed in  claim 1 , wherein said two peaks are separated by a distance of substantially 8.65 mm. 
     
     
         6 . A toothbrush as claimed in  claim 1 , wherein said peaks are configured for insertion into adjacent triangular gap regions between successive teeth. 
     
     
         7 . A toothbrush as claimed in  claim 1 , wherein said cleaning media defining said peaks at the middle region are stiffer than said cleaning media located at the side regions. 
     
     
         8 . A toothbrush as claimed in  claim 1 , wherein said cleaning media are bristles. 
     
     
         9 . A toothbrush as claimed in  claim 8 , wherein said cleaning media defining said peaks at the middle region has a larger width than said cleaning media located at the side regions. 
     
     
         10 . A toothbrush as claimed in  claim 1 , wherein the front region of the cleaning media is formed into an asymmetrical peak defining a slope on one side and a generally vertical end on the opposite side. 
     
     
         11 . A toothbrush as claimed in  claim 10 , wherein said asymmetrical peak is taller than said peaks arranged between the side regions of said cleaning media.
