摘要:
A toothbrush having an arrangement of cleaning elements for improved oral care and dentifrice retention. In one aspect, the invention is a toothbrush comprising a first set of cleaning elements forming a loop that extends from the distal periphery of the head to the proximal periphery of the head. The loop has the shape of a racetrack and comprises a first par-elliptical wall of cleaning elements at the distal periphery of the head and a second par-elliptical wall of cleaning elements located at the proximal periphery of the head. The par elliptical walls are connected first and second arcuate rows of cleaning elements. In one embodiment, the first and second arcuate rows are symmetrically arranged about the longitudinal axis so that peripheral convex surfaces of the first and second arcuate rows face the longitudinal axis.
摘要:
An oral care implement such as a toothbrush includes a head defining a longitudinal axis and a plurality of tooth cleaning elements supported by the toothbrush head. The tooth cleaning elements preferably include at least one tooth polishing unit having a polishing element including a supporting base and a broadened flexible tooth polishing head extending angularly outwards from the base and defining a polishing surface. In a preferred embodiment, the polishing element is made of an elastomeric material. In some embodiments, the polishing element may be comprised of a plurality of individual polishing members.
