Abstract
A toothbrush is provided having a brushhead, neck and handle. The handle includes a flex zone flanked on one side by the neck on the other by a tail zone of the handle. The neck and tail zone are rigid in contrast to the bendable flex zone. Spring Rate for the neck and tail zone is each greater than that for the flex zone. A relatively hard, unitarily formed backbone traverses neck and handle. An elastomer forms portions of both the flex and tail zones. Elastomer is anchored through at least one channel traversing a beam of the backbone. Ends of the channel are radiused to eliminate structural weakness.
