Abstract
An applicator device including at least one holding section, at least one working tip, and a neck section connecting the holding section and the working tip, the device also includes a base body formed at least partially from a first plastic component, the base body being at least partially overmolded by at least one second plastic component that is softer than the first plastic component. In the region of the working tip, the at least one second plastic component at least partially coats the base body, and the coating includes outwardly projecting, bristle-type cleaning elements.

An applicator device with at least one holding section, at least one working tip and a neck section connecting the holding section and the working tip, said device also comprising a base body at least partially formed from a first plastic component, the base body being at least partially overmolded with at least one second plastic component, which is softer than the first plastic component, wherein in the region of the working tip the at least one second plastic component at least partially coats the base body and wherein the coating comprises outwardly projecting cleaning elements.
A method for producing an applicator device or a comb of applicator devices by injection molding, wherein the applicator device(s) has/have at least one holding section, at least one working tip and a neck section connecting the holding section and the working tip,
- wherein in a first step one or more base bodies is/are injection molded at least partially from a first plastic component and
- wherein, after a repositioning process, in a second step the base body/bodies is/are at least partially overmolded with at least one second plastic component which is softer than the first plastic component,
- wherein the second plastic component at least partially coats the base body in the region of the working tip(s) and the coating forms outwardly projecting cleaning elements.
A tool for producing a comb of applicator devices by injection molding with at least a first cavity for injection molding the first plastic component for the base bodies and a second cavity for injection molding the second plastic component around the base body, wherein the first cavity for the first plastic component is modularly constructed from at least one rear section for at least the base body holding section and at least one front section for at least the base body tip and wherein the second cavity for the second plastic component is modularly constructed from at least one rear section for at least the holding cover and at least one front section for at least the coating.
