| 摘要 | A toothbrush featuring a graspable elongated handle defining a longitudinal axis, the handle comprising a neck region adjacent an end of the handle and a head disposed at the end of the handle. The head is carrying flexible bristles that extend outward from an outer surface of the head. The outer surface of the head is axisymmetric. The bristles are distributed about the head such that bristles extend in each of several radial directions, including from opposite sides of the head. At least some of the bristles are extending so as to overlay the longitudinal axis in opposite directions. | ||

| 主权项 | 1. A toothbrush comprising: a graspable elongated handle defining a longitudinal axis, the handle comprising a neck region adjacent an end of the handle and being formed of a hard core surrounded by a soft outer layer, the soft outer layer having a varying thickness that is thinner in the neck region than in handle grip regions; and a head disposed at the end of the handle and carrying flexible bristles that extend outward from an outer surface of the head, wherein the outer surface of the head is axisymmetric and wherein the bristles are distributed about the head such that bristles extend in each of several radial directions, including from opposite sides of the head, at least some of the bristles extending so as to overlay the longitudinal axis in opposite directions and the soft outer layer of the handle has a lower hardness than the core of the handle and the outer surface of the head. | ||
