Toothbrush

Abstract

The toothbrush has a triple cross array of tufts of bristles. The tufts are disposed in rows which are disposed on a diagonal relative to longitude and axis of the toothbrush. In addition, alternating rows of the tufts have the tufts inclined at an acute angle to the base of the toothbrush and in crisscrossing relation to the tufts of the adjacent row.

1 . A head for a tooth brush comprising 
 a body having an elongated shape along a longitudinal axis; and    a plurality of rows of tufts mounted on said body, at least some of said rows of tufts being disposed at an acute angle to said longitudinal axis of said body,    said tufts in each of said some of said rows of tufts being disposed at an acute angle to the plane of said body and in criss-crossing relation to said tufts in an adjacent row of tufts of said some of said rows of tufts.    
   
   
       2 . A head for a tooth brush as set forth in  claim 1  wherein said some of said rows of tufts are disposed at an acute angle of 27° to said longitudinal axis of said body.  
   
   
       3 . A tooth brush comprising 
 a body having an elongated shape along a longitudinal axis; and    a plurality of rows of tufts mounted on said body, said rows of tufts being disposed at an acute angle to said longitudinal axis of said body, said tufts in each of said rows of tufts being disposed at an acute angle to the plane of said body and in crisscrossing relation to said tufts in an adjacent row of tufts.    
   
   
       4 . A toothbrush as set forth in  claim 3  wherein said rows of tufts are disposed at an acute angle of 27° to said longitudinal axis of said body.  
   
   
       5 . A tooth brush as set forth in  claim 4  wherein said tufts in each said row are parallel and at an acute angle of 18° to said plane of said body.  
   
   
       6 . A tooth brush as set forth in  claim 3  wherein said tufts in each said row are parallel and at an acute angle of 18° to said plane of said body.  
   
   
       7 . A toothbrush as set forth in  claim 3  wherein each said tuft includes a plurality of bristles.  
   
   
       8 . A tooth brush as set forth in  claim 7  further comprising a retainer wall mounted on said body and located at one end of each said row of tufts for restraining said bristles of said tufts thereat from deforming during use.  
   
   
       9 . A toothbrush as set forth in  claim 8  wherein each said wall is parallel and spaced from a rearmost tuft in a respective row of tufts.  
   
   
       10 . A toothbrush as set forth in  claim 9  wherein each said wall is one-half the height of an adjacent tuft.  
   
   
       11 . A toothbrush as set forth in  claim 3  wherein said body is of a rectangular shape.  
   
   
       12 . A tooth brush as set forth in  claim 3  wherein each said tuft has a predetermined diameter and said tufts in each said row are spaced apart on a centerline-to-centerline distance of twice said predetermined diameter.  
   
   
       13 . A toothbrush as set forth in  claim 12  wherein said rows of tufts are spaced apart from each other.
