Curved toothbrush

Abstract

A curved toothbrush includes a plurality of bundled fine bristles adapted to frictionally brush teeth and gums and a curved body plate adapted to plant the plurality of fine bristles thereinto at uniform intervals, wherein the curved body plate includes a curved underside and a curved top formed curvedly by twisting both ends of the curved body plate in a longitudinal direction thereof (in a direction of X-X′), the curved top having obliquely protruding portions formed on both sides thereof in an oblique direction (in a direction of Z-Z′) and an obliquely concaved groove formed between the obliquely protruding portions, so that all of users can keep clean and healthy teeth.

1 . A curved toothbrush comprising:
 a plurality of bundled fine bristles having the same length as each other to frictionally brush teeth and gums;   a curved body plate adapted to plant the plurality of fine bristles thereinto at uniform intervals; and   a neck and a handle extended unitarily from the curved body plate,   wherein the curved body plate comprises a curved underside and a curved top formed curvedly by twisting both ends of the curved body plate in a longitudinal direction thereof (in a direction of X-X′), the curved top having obliquely protruding portions formed on both sides thereof in an oblique direction (in a direction of Z-Z′) and an obliquely concaved groove formed between the obliquely protruding portions,   wherein distal ends of the plurality of bundled fine bristles at a first end of the curved body plate and a second end of the curved body plate in the X-X′ direction extend orthogonally a first distance from the X-X′ direction and distal ends of the plurality of bundled fine bristles at a center of the curved body plate extend orthogonally a second distance from the X-X′ direction, wherein the second distance is greater than the first distance, and   wherein the neck and the handle are formed obliquely from a plane of the curved body plate, and the neck extends upwardly from the second end of the body plate along the X-X′ direction to the handle, the handle extending at an oblique angle of 2 degrees to 3 degrees with respect to the X-X′ direction of the curved body plate.   
     
     
         2 . The curved toothbrush according to  claim 1 , wherein the plurality of bristles has tooth frictional surfaces formed along the same shape as the twistedly curved underside. 
     
     
         3 . The curved toothbrush according to  claim 1 , wherein the plurality of bundled fine bristles have tooth frictional surfaces that are extended radially to a larger area than the plane area of the curved underside. 
     
     
         4 . The curved toothbrush according to  claim 1 , wherein the handle is curvedly extended from the curved body plate to a different height from each other. 
     
     
         5 . (canceled) 
     
     
         6 . The curved toothbrush according to  claim 1 , wherein the curved body plate and the handle are twistedly formed.
