Abstract
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.

A toothbrush comprising:
- 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 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.
A method of making a toothbrush, the method comprising:
- forming a lower toothbrush head section by anchoring lower bristle tufts in a lower toothbrush head shell having a circular rim, with the lower bristle tufts extending in multiple radial directions;
- forming an upper toothbrush head section by anchoring upper bristle tufts in an upper toothbrush head shell having a circular rim, with the upper bristle tufts extending in multiple radial directions;
- and then
- spin-welding the rims of the upper and lower toothbrush head section shells together to form a sealed toothbrush head.
