A cosmetic applicator having a core that supports the application elements in the form of bristles and/or comb tines; the core has a central body that is itself equipped with a plurality of bristles and/or comb tines protruding out directly from it; the core is also composed of at least one arm that protrudes out from the central body and is itself equipped with a plurality of bristles and/or comb tines and is mobile relative to the central body.

Foldable applicator

A brush with a bristle support tube and a set of injection-molded bristles, which are affixed to the bristle support tube, extend through the outer wall of the bristle support tube, and are of one piece with a plastic element that fills at least a part of the inside of the bristle support tube; the interior of the bristle support tube has at least one dividing wall that divides the interior of the bristle support tube into compartments that are separate from one another.

One-piece, multi-component injection-molded brush and method for producing it

The invention relates to a method for producing a brush, particularly in the form of a mascara applicator, with bristles injection molded out of different injection molding compounds, using an injection mold that has a main cavity, which forms the bristle support, and secondary cavities branching off from this, with each secondary cavity forming a single bristle and with at least one first injection molding compound being injected into the main cavity, followed by a second injection molding compound in successive steps; at least one slider is inserted into the main cavity and closes part of the secondary cavities so that the first injection molding compound only travels into another part of the secondary cavities after which the slider is withdrawn and the second injection molding compound is injected so that it travels into the secondary cavities previously closed by the slider.

Cosmetic brush

The invention relates to a cosmetics applicator having a handle section, an applicator element and a shaft section connecting the applicator element and the handle section, wherein the applicator element includes a core element of a first material and a bristle element which at least partially envelops the core element and includes a second material preferably different from the first material with regard to its hardness and/or flexibility.

Applicator with tubular, overmolded core element

The part of a cosmetics unit is an applicator in the form of a brush (). It is implemented as a sandwich injection-molded part consisting of two different plastic component s (). A first inner plastic component () is injected by means of a single joint injection point () into a second outer plastic component (). The first inner plastic component () and the second outer plastic component () precisely rest against each other everywhere with regard to their contours. A connecting area is formed, so as to be free of gaps everywhere, between the first inner plastic component () and the second outer plastic component (). The second outer plastic component () completely encloses the first inner plastic component (), with the exception of the injection point (). The sandwich injection-molded part () has a total weight of at most 10 g.
