Abstract

Eine Zahnbürste weist einen aus einem 1. Kunststoff bestehenden Bürstenkopf auf, in dem zumindest eine in Umfangsrichtung vollständig geschlossene Ausnehmung ausgebildet ist. In der Ausnehmung ist ein Trägerkörper aus einem gegenüber dem 1. Kunststoff verformungsweicheren 2. Kunststoff angeordnet. Zumindest auf dem Trägerkörper ist ein Borstenbesatz in Form von Borstenbündeln und/oder Einzelborsten vorgesehen. Dabei ist der Trägerkörper in Verbindungsabschnitten nur auf einer Seite seines Außenumfangs mit der umgebenden Innenwandung der Ausnehmung verbunden, wobei die Verbindungsabschnitte nur einen Teil des Außenumfangs des Trägerkörpers umfassen.

Figure imgaf001
A toothbrush has a brush head consisting of a first plastic in which at least one recess which is completely closed in the circumferential direction is formed. In the recess, a carrier body is arranged from a plastic which is softer than the first plastic. At least on the carrier body, a bristle stocking in the form of bristle bundles and / or single bristles is provided. In this case, the carrier body is connected in connection portions only on one side of its outer circumference with the surrounding inner wall of the recess, wherein the connecting portions comprise only a part of the outer periphery of the carrier body.
