摘要： A toothbrusch 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.

摘要： A toothbrush is described whose head (8) has a special arrangement of bristle tufts. The arrangement includes a fan-shaped grouping of tufts (26) along left and right edges (22, 24) of the head (8). Near the front and rear ends (10, 12) of the head (8) are a grouping of tufts (36, 44) whose free ends are trimmed to define respective planes slanting downwardly towards the interior area of the head (8). Within the interior area is a further grouping of tufts arranged in a saddle-shape.

摘要： A toothbrush (1) is described whose handle (4) has a special arrangement. The handle (4) includes an elongated handle arm (14) formed of a plastic having a Shore Hardness value of at least 90. A pressure pad (16) is attached to the arm (14) and formed of an elastomer having a Shore Hardness value no higher than 80. Advantageously, the elongated handle arm (14) has a recess (18) in an area adjacent to connection with the brushhead. The pressure pad (16) is arranged within the recess (18). At least one radial anti-slip structure, especially a semi-ring shape (22), protrudes from and circumscribes bottom and lateral surfaces of the arm.
