Title:
POWERED TOOTHBRUSH WITH BRISTLES HAVING RANDOM MOTION
Document Type and Number:
WIPO Patent Application WO/2018/214949
Kind Code:
A1
Abstract:
A powered toothbrush includes a plurality of rows of bristle tufts (125) that project through a perforated top shell (130) of a hollow toothbrush head. Ends of individual bristles are held in buckets (420) to form the tufts (125) and the bristle ends opposite the bucketed ends are free. The bucketed ends of the bristle tufts (125) are captured within the internal space (415) within the head but are not fixedly attached to any other toothbrush component or structure. This non-fixed attachment feature enables the bristle tufts (125)to have multiple degrees of freedom of motion with respect to the perforations in the top shell and can rotate, move axially and tilt.
