Zahnbürste

摘要

A toothbrush consists of a brush body made of plastic with a head, a neck and a handle as well as bunches of bristles, the free ends of the bristles of at least some of the bunches forming an enveloping surface with a cone angle alpha of 30 DEG to 90 DEG and the neck of the brush body resiliently yielding at a force K of 500 to 1200 g contact pressure on the bristles, the cone angle alpha and the contact pressure force K being approximately inversely proportional.
