Definitions
- the invention relates generally to the field of oral care, and in particular to toothbrushes. BACKGROUND OF THE INVENTION
- U.S. Patent 2,242,743 discloses a toothbrush having a handle 12, a head 14, and a plurality of tufts 16 of bristles which extend outward from the head.
- the tufts are positioned at an acute or obtuse angle with respect to the handle and head.
- the bristles provide a series of transverse, broad, inverted V-shaped areas on the working surface 18.
- the free ends of the bristles of each tuft form a surface which is inclined away from the direction in which the tuft is inclined.
- U.S. Patent 3,085,273 discloses a toothbrush having a handle 10 with an elongated head portion 12 formed integrally with the head. Bristles 14 are mounted in the head portion and are formed in tufts 15. The tufts are arranged in parallel rows 16, 16' longitudinally of the head and inclined in the direction of the rows. The free end of the bristles of each tuft define a plane which is perpendicular to the direction in which the tuft extends from the head.
- a toothbrush includes a handle, a head extending from the handle, and a tuft of bristles extending from the head.
- the tuft is inclined such that the angle of inclination is an acute angle relative to a surface of the head through which the tuft extends.
- the bristles have free ends which define a plane, the plane being other than perpendicular to a direction in which the tuft extends from the head. The plane is tilted towards the same direction in which the tuft is inclined.
