POWER TOOTHBRUSH BRUSHHEAD WITH FULID-DIRECTING MEMBER

Japanese Patent JP2011189199
Kind Code:
A
Abstract:

To provide a brushhead adapted for cleaning teeth as part of a power toothbrush and including a brushhead member which includes a bristle field, as for the brushhead in operation moves in a reciprocating action, wherein as much fluid as possible from the action of bristles is directed toward the teeth and gums of a user providing cleaning and a sensory effect for the user.

In one embodiment, the brushhead includes a rim member which extends around at least a substantial portion of the brushhead, the rim member extending around the entire bristle field and having an upper edge which is lower than the top of the bristles. The rim member has a different flexibility than the bristles so that the movement of the rim member and the bristles is out of phase during operation of the toothbrush, which results in fluid from the bristles being directed toward the teeth during operation of the toothbrush.
