The invention relates to bristles used to administer media (6, 5, 52, 53) which are produced as follows: a filament which can be cut to form a bristle and which comprises (3) a core that co-determines the mechanical properties of said bristle is extruded. The bristle comprises recesses (4), positioned at a distance from one another, which radiate outwards from the centre of the core, open out onto the periphery of the filament and are filled externally with the medium. The recesses comprising said peripheral opening are configured in such a way that the medium is only dispensed under conditions which are in accordance with the requirements for use of the brush. Alternatively, the recesses can also have a greater open width and can be covered by a layer or a jacket (7). The invention also relates to a bristle and to brushware comprising bristles of this type. |
