Abstract
The invention relates to a method and a device for producing a toothbrush () or part thereof by the two-component or multi-component injection-molding process. To produce in the brush body segments () that are isolated from the rest of the brush body, a mold () which comprises three hollow regions () is used. Two of these hollow regions () that are separate from one another serve for producing the segments () and the other regions () of the toothbrush () from a first component (). A third hollow region () serves for distributing material to the segments () that are isolated from one another and from the other regions (), or the corresponding hollow region (). The material () remaining behind there is removed and sent for disposal. In a further step, connecting elements () between the segments () and/or the other regions () are injection-molded from a second component ().
