Toothbrush with angled tufts and/or different types of tufts with differing cross-sectional areas

摘要

A toothbrush (10) having a handle (12) and a plurality of tufts of bristles (26) secured to the head (14). In one embodiment one of the tufts is secured to the head (14) at a location such that no other tuft is secured to the head at a location that is more distal from the handle (12) than the location where the one tuft is secured to the head (14). The one tuft is angled by about 81 degrees or less relative to an imaginary line which is tangent to a co-planar with a surface of the head through which the one tuft secured to the head (14). The one tuft is tilted away from the handle (12) towards a direction along which the head (14) extends from the handle (12). Various other embodiments are disclosed with the common features being at least two longitudinal rows of tufts tilting in opposite longitudinal directions.
