发明名称 HANDHELD TOOTHBRUSH
摘要 The invention is directed to a handheld toothbrush (1) with a brush head (4) having a forward free end (5) and a rearward portion (6). Adjoining the rearward portion (6) is a handle (2). Provided at the forward free end (5) of the brush head (4) is at least one bristle tuft (21) of a first set (8), which extends upwardly away from the bristled surface (7) of the brush head (4). Adjoining the first set (8) in rearward direction is a second set (9) of bristle tufts (25, 26), which is comprised of several bristle tufts (25) which protrude from the surface (7), are arranged serially on a ring area, and extend in the circumferential direction of the ring area at an angle of inclination relative to the surface (7) of the brush head (4), said second set comprising in addition at least one further tuft (26) that protrudes from the surface (7) and extends within the bristle tufts (25) arranged on the ring area. According to the invention a third set (10) of bristle tufts (28) adjoins the second set (9) of bristle tufts (25) in the direction towards the rearward portion (6), said third set being comprised of several bristle tufts (28) which protrude from the surface (7) and are arranged serially on a ring area. The bristle tufts (28) of the third set (10) are inclined in the circumferential directionin opposition to the direction of the bristle tufts (25) of the second set (9). As a result these bristle tufts (25, 28) are capable of penetrating optimally between this user's teeth, hence ensuring a better cleaning result.
