Patent abstract
The inventive handle for a brush, in particular for a toothbrush or a domestic brush, has an integral handle body with a hollow space which is surrounded by a wall. Recesses which are offset in relation to one another and open into the hollow space are formed in the wall. The handle is produced from a plastic in an injection-molding process using an injection-molding die which has finger elements, with sections of these finger elements touching in a sealing manner when the injection-molding die is in the closed state and, as a result, these finger elements forming the recesses and the hollow space in the hardened handle.
