Description

Die Erfindung richtet sich auf eine Bürste, insbesondere eine Mascara-Bürste, wobei eine Mehrzahl von Borsten zwischen verdrillten Drahtabschnitten festgelegt ist und sich von diesen verdrillten Drahtabschnitten nach allen Seiten wegerstreckt.The invention is directed to a brush, in particular a mascara brush, a plurality of bristles being fixed between twisted wire sections and extending in all directions from these twisted wire sections.

Derartige Bürsten, insbesondere Mascara-Bürsten sind seit vielen Jahren bekannt. Während solche Bürsten, die ursprünglich mit Naturborsten, z.B. Ziegenborsten, bestückt wurden mit einem derartigen Besatz aufgrund des unrunden Querschnitts der Naturhaare und der Röhrenstruktur dieser Naturhaare eine gleichmäßige Spitzenverteilung aufwiesen, gaben später unter Verwendung von Kunstfasern mit rundem, vollem Querschnitt hergestellte Bürsten die Verdrillungskonfiguration der Drähte in Form von schraubenförmigen Windungen bei der Verteilung der Borstenspitzen wieder.Such brushes, in particular mascara brushes, have been known for many years. While such brushes, originally with natural bristles, e.g. Goat bristles, equipped with such a stock due to the non-circular cross-section of the natural hair and the tubular structure of these natural hair, had an even tip distribution, later gave brushes made using synthetic fibers with a round, full cross-section, the twisting configuration of the wires in the form of helical turns during the distribution of the Bristle tips again.

Diese Strukturierung wurde bei Mascara-Bürsten zunächst begrüßt. Im laufe der weiteren Entwicklung versuchte man dann, insbesondere für Mascaraprodukte bestimmter Zusammensetzung und Konsistenz, wieder die mit Naturhaaren ursprünglich bereits einmal realisierte gleichmäßige Spitzenverteilung der Borsten über die Mantelfläche der Bürste zu erzielen.This structuring was initially welcomed for mascara brushes. In the course of further development, attempts were then made, particularly for mascara products of a certain composition and consistency, to once again achieve the uniform distribution of the bristles over the surface of the brush, which was originally achieved with natural hair.

Hierzu ist gemäß der EP-A-o 25o 68o vorgesehen, daß Kunstfasern mit einem unrunden, z.B. kreuzförmigen, oder mit einem rohrförmig hohlen Querschnitt verwendet werden, um auf diese Weise die unrunde Konfiguration von Tierhaaren, wie z.B. Ziegenhaaren, nachzuempfinden.For this purpose, according to EP-A-o 25o 68o it is provided that synthetic fibers with a non-circular, e.g. cruciform, or with a tubular hollow cross-section can be used in this way to the non-circular configuration of animal hair, such as Goat hair, to empathize.

Für manche Anwendungsfälle sind aber Borsten aus Hohlfasern oder mit kreuzförmigem Querschnitt nicht geeignet, insbesondere weil diese Fasern teilweise dazu neigen, aufgrund einer gewissen Kapillarwirkung zwar Mascaraflüssigkeit aufzunehmen, andererseits aber das Abgabeverhalten bei bestimmten Mascara-Viskositäten nicht befriedigend ist.For some applications, however, bristles made of hollow fibers or with a cross-shaped cross-section are not suitable, in particular because these fibers tend to absorb mascara liquid due to a certain capillary action, but on the other hand the delivery behavior is not satisfactory at certain mascara viscosities.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Bürste, insbesondere eine Mascara-Bürste der eingangs genannten Art so auszugestalten, daß vorteilhafte Auftragseigenschaften und eine möglichst gleichmäßige Spitzenverteilung erreicht werden, ohne daß dann, wenn dies nicht wünschenswert erscheint, Kapillareffekt in Kauf genommen werden müssen.Proceeding from this, the invention is based on the object of designing a brush, in particular a mascara brush of the type mentioned at the outset, in such a way that advantageous application properties and as uniform a tip distribution as possible are achieved without, if this does not appear to be desirable, a capillary effect being accepted have to.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Borsten als Abschnitte von im Querschnitt runden Fasern gebildet sind, deren Durchmesser in Längsrichtung gesehen abwechselnd größer und kleiner ist.This object is achieved in that the bristles are formed as sections of round fibers in cross section, the diameter of which, viewed in the longitudinal direction, is alternately larger and smaller.

Vorzugsweise werden solche Fasern verwendet, welche bei der Extrusion mit wechselnden Abzugskräften abgezogen werden, so daß dementsprechend ein sich entsprechend den wechselnden Abzugskräften periodisch verändernder Durchmesser entsteht.Those fibers are preferably used which are drawn off during the extrusion with changing pulling forces, so that accordingly a diameter which changes periodically in accordance with the changing pulling forces arises.

Die Verwendung solcher Fasern führt zu sehr volumigen, eine gleichmäßige Spitzenverteilung aufweisenden Bürsten, was dadurch bedingt ist, daß die verdrillten Drähte an den Borsten statistisch verteilt einmal in Bereichen größeren und einmal in Bereichen kleineren Durchmessers angreifen und dementsprechend eine statistische Verteilung der geometrischen Angriffsverhältnisse der Drähte an den Borsten entsteht, welche sich wiederum in einer statistischen Verteilung der Spitzen der Borsten wiederspiegelt.The use of such fibers leads to very voluminous, evenly distributed brushes, which is due to the fact that the twisted wires on the bristles attack statistically distributed once in areas of larger and once in areas of smaller diameter and accordingly a statistical distribution of the geometrical attack conditions of the wires arises on the bristles, which in turn is reflected in a statistical distribution of the tips of the bristles.

Ein ähnlicher Effekt statistisch verteilter Angriffsverhältnisse hinsichtlich des Festhaltens der Borsten wird dadurch erreicht, daß die Drähte einen unrunden Querschnitt aufweisen, wobei insbesondere vorgesehen sein kann, daß die Drahtabschnitte im Querschnitt rechteckig, z.B. quadratisch sind.A similar effect of statistically distributed attack conditions with regard to the retention of the bristles is achieved in that the wires have a non-circular cross section, it being possible in particular to provide that the wire sections have a rectangular cross section, e.g. are square.

Derartige Drähte sind kommerziell in den zur Herstellung von Bürsten erforderlichen Qualitäten verfügbar und ermöglichen dementsprechend eine rationelle Herstellbarkeit. Mit derartigen Drähten wird bei der Verwendung von gestreckten Fasern der bei solchen Fasern erzielte Effekt noch verstärkt, jedoch läßt sich unter Verwendung derartiger Drähte auch mit herkömmlichen, in Längsrichtung eine gleichmäßige Dicke aufweisenden Fasern eine mehr oder weniger statistische Verteilung der Spitzen erreichen.Wires of this type are commercially available in the qualities required for the production of brushes and accordingly enable rational producibility. With such wires, the effect achieved with such fibers is further enhanced when using stretched fibers, however, using such wires can also achieve a more or less statistical distribution of the tips with conventional fibers having a uniform thickness in the longitudinal direction.

Eine weitere Modifikation des erfindungsgemäßen Grundgedankens eine statistische Verteilung der Kraftwechselwirkung zwischen Borsten und Drahtabschnitten zu erreichen, besteht darin, daß Drahtabschnitte mit strukturierter Oberfläche verwendet werden. Durch eine derartige Oberlächenstruktur begegnet jede einzelne zwischen den Drahtabschnitten festgelegte Borste unterschiedlich gerichteten Haltekräften, was wiederum zu einer weitestgehend gleichmäßigen Spitzenverteilung führt.A further modification of the basic idea of the invention to achieve a statistical distribution of the force interaction between bristles and wire sections consists in that wire sections with a structured surface are used. With such a surface structure, each individual bristle fixed between the wire sections encounters differently directed holding forces, which in turn leads to a largely uniform tip distribution.

Weiterhin kann im Rahmen der Erfindung vorgesehen sein, daß die Drahtabschnitte mit einem relativ weichen Kunststoffüberzug versehen sind. Auch hierdurch werden die definierten geometrischen Verhältnisse, welche zwischen gleichmäßig runden Fasern einerseits und gleichmäßig runden Drahtquerschnitten andererseits sonst zur Ausbildung einer Schraubenkonfiguration führen,aufgelöst, was wiederum zu einer Veränderung des Erscheinungsbildes im Sinne einer gleichmäßigeren Spitzenverteilung führt.Furthermore, it can be provided in the context of the invention that the wire sections are provided with a relatively soft plastic coating. This also resolves the defined geometric relationships, which lead to the formation of a screw configuration between uniformly round fibers on the one hand and uniformly round wire cross sections on the other hand, which in turn leads to a change in appearance in the sense of a more uniform tip distribution.

Die Verwendung von kunststoffüberzogenen Drahtabschnitten ist von Dentalbürsten her an sich bekannt, wobei der Kunststoffüberzug dort dazu dient, bei der Zahnreinigung als schmerzhaft empfundene elektrische Potentiale zwischen Draht und Amalgamfüllungen zu vermeiden. Außerdem sind auch schon Reinigungsbürsten, z.B. für Möbel, mit derart kunststoffüberzogenen Drahtabschnitten bekanntgeworden, wobei der Kunststoff dort im wesentlichen dazu dienen soll, bei einem Kontakt mit einem zu reinigenden Kraftfahrzeug oder Möbelteil eine Beschädigung dieser Teile durch die blanke Drahtoberfläche zu vermeiden.The use of plastic-coated wire sections is known per se from dental brushes, the plastic coating there serving to clean electrical potentials perceived as painful between wire and Avoid amalgam fillings. In addition, cleaning brushes, for example for furniture, with such plastic-coated wire sections have already become known, the plastic there essentially serving to prevent damage to these parts by contact with a motor vehicle or furniture part to be cleaned by the bare wire surface.

Insbesondere bei Mascara-Bürsten kann durch den Kunststoffüberzug neben dessen Einfluß auf die Spitzenverteilung auch noch ein weiterer vorteilhafter Effekt dadurch erzielt werden, daß dieser so ausgewählt wird, daß er Mascara-Trägerflüssigkeit abweisende Oberflächeneigenschaften aufweist. Hierdurch wird erreicht, daß sich die Mascaraflüssigkeit, was bei bekannten Mascara-Bürstchen häufig zu beobachten ist, nicht an der Oberfläche der Drähte zwischen benachbarten Borsten festsetzt, was zu Verklumpungen führt, welche sich wiederum auf den Wimpern absetzen können.In the case of mascara brushes in particular, in addition to its influence on the tip distribution, the plastic coating can also achieve a further advantageous effect by selecting it in such a way that it has surface properties which repel mascara carrier liquid. This ensures that the mascara liquid, which is often observed in known mascara brushes, does not attach to the surface of the wires between adjacent bristles, which leads to clumping, which in turn can settle on the eyelashes.

Bei Verwendung derartiger Mascara-Bürstchen für Mascaraflüssigkeiten auf Wasserbasis wird man dementsprechend vorzugsweise einen Kunststoff verwenden, welcher entweder von vornherein hydrophobe Oberflächeneigenschaften aufweist, oder dessen Oberfläche zur Erzielung solcher Eigenschaften nachträglich entsprechend behandelt wird.Accordingly, when using such mascara brushes for water-based mascara liquids, one will preferably use a plastic which either has hydrophobic surface properties from the outset or whose surface is subsequently treated accordingly to achieve such properties.

Die mit Kunststoff überzogenen Drahtabschnitte lassen sich günstigerweise dadurch realisieren, daß der Kunststoffüberzug auf den Draht durch Extrusion aufgebracht wird.The plastic-coated wire sections can be advantageously implemented by applying the plastic coating to the wire by extrusion.

Insbesondere bei einem derartigen Aufbringen durch Extrusion ist es durch die Verwendung entsprechender Extrusionsdüsen auch möglich, die Oberfläche des Kunststoffüberzugs strukturiert auszubilden und auf diese Weise die vorstehend beschriebenen "statistischen" Eingriffseigenschaften noch zu verstärken.In particular in the case of such an application by extrusion, it is also possible, by using appropriate extrusion nozzles, to structure the surface of the plastic coating and in this way to further strengthen the "statistical" engagement properties described above.

Bei allen vorstehend beschriebenen Ausführungsformen ist es möglich, die Borsten nach dem Verdrillen der Drähte unter Erzeugung eines asymmetrischen Bürstenquerschnitts zu beschneiden, so daß z.B. je nach den gewünschten Auftragseigenschaften die Seite mit kürzeren und dementsprechend sich steifer verhaltenden Borsten oder die Seite mit längeren und sich dementsprechend weicher verhaltenden Borsten verwendet werden kann.In all of the embodiments described above, it is possible to cut the bristles after twisting the wires to produce an asymmetrical brush cross-section, so that e.g. depending on the desired application properties, the side with shorter and accordingly stiffer bristles or the side with longer and accordingly softer bristles can be used.

Bei einer weiteren Ausführungsform sind die Borsten aus zwei Kunststoffkomponenten ausgebildet, wobei die innere Komponente eine Art weiche Seele bildet und von einem härteren Kunststoff mantelartig umgeben wird. Durch eine derartige Konfiguration wird der Aufbau von Naturhaar nachgeahmt und dementsprechend eine vergleichbare Wirkung wie bei Naturhaar erreicht.In a further embodiment, the bristles are formed from two plastic components, the inner component forming a kind of soft core and surrounded by a harder plastic like a jacket. Such a configuration mimics the build-up of natural hair and accordingly achieves an effect comparable to that of natural hair.

Weiterhin kann vorgesehen sein, daß die Borsten als Hohlfasern ausgebildet sind, welche durch eine Mehrzahl von inneren Stegen unterbrochen sind. Beispielsweise können die inneren Stege annähernd kreuzförmig angeordnet sein, so daß der Hohlraum der Hohlfaser in vier Kapillaren sehr kleinen Querschnitts aufgeteilt wird. Hierdurch wird eine unerwünschte Kapillarwirkung bei größeren Querschnitten vermieden.Furthermore, it can be provided that the bristles are designed as hollow fibers which are interrupted by a plurality of inner webs. For example, the inner webs can be arranged in an approximately cross shape, so that the hollow fiber cavity is divided into four very small cross-section capillaries. This avoids an undesirable capillary effect in the case of larger cross sections.

Eine weitere Ausführungsform sieht vor, daß die Borsten im Querschnitt S-förmig ausgebildet sind, wobei die S-Biegungen sich nahezu vollständig kreisförmig erstrecken und die Längskanäle ausbilden.A further embodiment provides that the bristles are S-shaped in cross-section, the S-bends extending almost completely circularly and forming the longitudinal channels.

Eine andere Ausführungsform sieht vor, daß die verwendeten Fasern in sich gewellt bzw. onduliert sind oder daß sie zackenförmig verlaufen, was z.B. durch eine Behandlung mit einer Zahnradkombination nach der Extrusion erreicht werden kann, oder daß sie auch nur gebogen sind, was ebenfalls zu einer statistischen, ungleichmäßigen Spitzenverteilung führt.Another embodiment provides that the fibers used are undulated or undulated in themselves or that they are jagged, which e.g. can be achieved by treatment with a gear combination after extrusion, or that they are even bent, which also leads to a statistical, uneven tip distribution.

Letztlich kann auch noch vorgesehen sein, daß die verwendeten Drahtabschnitte als innen hohle Drahtrohrabschnitte ausgebildet sind, um beim Verdrillen derselben von Ort zu Ort unterschiedliche Festhalteverhältnisse zu schaffen.Ultimately, it can also be provided that the wire sections used are designed as internally hollow wire tube sections, in order to create different holding conditions when twisting them from place to place.

Eine in der Zeichnung dargestellte Mascara-Bürste umfaßt zwei Drahtabschnitte 1,2, welche durch Umbiegen eines durchgehenden Drahtstükkes 3 entstehen. Zwischen diese Drahtabschnitte 1,2 ist in an sich bekannter Weise eine Mehrzahl von Borsten 4 eingelegt, wobei durch Verdrillen der Drahtabschnitte erreicht wird, daß die Spitzen 5 der Borsten 4 von den Drahtabschnitten 1,2 nach allen Seiten wegstehen, wie dies in Fig. 1 dargestellt ist, wobei aus Fig. 1 auch noch ersichtlich ist, daß die Drahtabschnitte 1,2 endseitig in einem Griff 6 festgelegt sind.A mascara brush shown in the drawing comprises two wire sections 1, 2, which are created by bending a continuous piece of wire 3. A plurality of bristles 4 is inserted between these wire sections 1, 2 in a manner known per se, twisting of the wire sections ensuring that the tips 5 of the bristles 4 protrude from the wire sections 1, 2 on all sides, as shown in FIG. 1, with FIG. 1 also showing that the wire sections 1, 2 are fixed in a handle 6 at the end.

Um die in Fig. 1 erkennbare gleichmäßige Verteilung der Spitzen 5 zu erreichen, gibt es verschiedene in Verbindung mit den Fig. 3 bis 6 veranschaulichte Möglichkeiten, denen der Grundgedanke gemeinsam ist, daß man versucht von Borste zu Borste unterschiedliche Angriffsverhältnisse der Drahtabschnitte 1,2 zu schaffen, so daß die durch das Verdrillen der Drahtabschnitte 1,2 entstehende Schraubenstruktur aufgelöst wird und sich in der Verteilung der Spitzen 5 nicht mehr wiederspiegelt.In order to achieve the uniform distribution of the tips 5 which can be seen in FIG. 1, there are various possibilities illustrated in connection with FIGS. 3 to 6, which have the basic idea that one tries to attack the bristle sections 1, 2 from bristle to bristle to create, so that the screw structure resulting from the twisting of the wire sections 1, 2 is dissolved and is no longer reflected in the distribution of the tips 5.

Bei dem in Fig. 3 dargestellten Ausführungsbeispiel sind die Drahtabschnitte 1,2 aus einem Runddraht 3 gebildet. Die Borsten 4 sind durch Abschnitte von Fasern gebildet, welche in Längsrichtung gesehen unterschiedliche Durchmesser D1,D2 aufweisen, wobei jedoch die Querschnittskonfiguration über die gesamte Länge jeweils rund ist.In the embodiment shown in FIG. 3, the wire sections 1, 2 are formed from a round wire 3. The bristles 4 are formed by sections of fibers which, viewed in the longitudinal direction, have different diameters D1, D2, but the cross-sectional configuration is round over the entire length.

Wie in Fig. 3 vergrößert und übertrieben dargestellt, kommen statistisch verteilt zwischen den Drahtabschnitten 1,2 einmal Borstenabschnitte mit dem maximalen Durchmesser D1 und einmal Borstenabschnitte mit dem minimalen Durchmesser D2 und kontinuierlich dazwischen liegenden Durchmessern zu liegen, so daß für jede Borste 4 unterschiedliche Haltebedingungen entstehen und sich dementsprechend die einzelnen Borsten in unterschiedlichen Winkeln von den Drahtabschnitten 1,2 bezogen jeweils auf deren Längsachsen im Haltepunkt wegerstrecken. Dies führt zu der in Fig. 1 dargestellten gleichmäßigen Verteilung der Spitzen 5.As enlarged and exaggerated in Fig. 3, there are statistically distributed between the wire sections 1,2 once bristle sections with the maximum diameter D1 and once bristle sections with the minimum diameter D2 and continuously intermediate diameters, so that 4 different holding conditions for each bristle arise and accordingly the individual bristles extend at different angles from the wire sections 1, 2 in relation to their longitudinal axes at the stopping point. This leads to the uniform distribution of the tips 5 shown in FIG. 1.

Bei einer alternativen Ausführungsform, wie sie in Fig. 4 dargestellt ist, weisen die runden Drahtabschnitte 1', 2' eine rauhe Oberfläche 7 auf, so daß auch hierdurch keine definierten Winkelverhältnisse am Festhaltepunkt der Borste 4 gegeben sind und eine gleichmäßige Spitzenverteilung erreicht wird.In an alternative embodiment, as shown in Fig. 4, the round wire sections 1 ', 2' have a rough surface 7, so that this also does not give defined angular relationships at the holding point of the bristle 4 and an even tip distribution is achieved.

Bei der Ausführungsform nach Fig. 5 weisen der Draht 3 und dementsprechend die Drahtabschnitte 1 ",2" einen quadratischen Querschnitt auf. Die Spitzen der Borsten 4 erstrecken sich radial nach außen in Abhängigkeit davon, wo in jedem Einzelfall die Kanten 8 an der Borste angreifen.5, the wire 3 and, accordingly, the wire sections 1 ", 2" have a square cross section. The tips of the bristles 4 extend radially outwards depending on where the edges 8 engage the bristle in each individual case.

Bei der Ausführungsform nach Fig. 6 sind die Drahtabschnitte 1 "', 2'" mit einem Kunststoffmantel 9 aus weichem Kunststoff umgeben, der im Angriffsbereich an den Borsten 4 zusammengedrückt wird. Bei Verwendung eines Mascara-Bürstchens für Mascaraprodukte auf Wasserbasis wird der Kunststoffmantel 9 bzw. die Oberfläche des Kunststoffmantels 1o so eingestellt, daß die Oberfläche wasserabstoßend ist, so daß das Festsetzen von Mascaraprodukt an der Oberfläche der Drähte vermieden wird.In the embodiment according to FIG. 6, the wire sections 1 "', 2'" are surrounded by a plastic sheath 9 made of soft plastic, which is pressed together at the bristles 4 in the area of attack. When using a mascara brush for water-based mascara products, the plastic sheath 9 or the surface of the plastic sheath 10 is adjusted so that the surface is water-repellent, so that the mascara product is prevented from sticking to the surface of the wires.
