Abstract:

A toothbrush handle comprising a terminal end, a connector end, an outer surface, an inner cavity and a longitudinal axis. The inner cavity has a surface defining a cross-sectional area. The inner surface has at least one of a greater cross-sectional area bordered by two lesser cross-sectional areas along the longitudinal axis or a lesser cross-sectional area bordered by two greater cross-sectional areas along the longitudinal axis. The outer surface defines an outer surface cross-sectional area. A wall is formed from the outer cavity surface to the inner cavity surface. The toothbrush handle comprises a single unitary component. The difference between the outer cross-sectional area and the inner cavity surface cross-sectional area varies less than 25 % over at least 50% of the toothbrush handle length along the longitudinal axis.
