The tips (8) of the shorter bristles each have a spacing from the twisted brush wire handle (3,4) to extend orthogonally from them.

Description

Die Erfindung richtet sich auf eine Mascara-Bürstchen umfassend eine Mehrzahl zwischen zwei verdrillten Drahtabschnitten gehaltener Borsten, wobei die Borsten durch Beschneiden unterschiedlich lang sind.The invention is directed to a mascara brush comprising a plurality of bristles held between two twisted wire sections, the bristles being of different lengths by trimming.

Derartige Mascara-Bürstchen müssen einerseits gute Transfereigenschaften haben, um die Mascara-Flüssigkeit aus einem Vorratsbehälter auf die Wimpern der Benutzerin zu transferieren, andererseits müssen vorteilhafte Auftragseigenschaften gegeben sein, um die transferierte Mascara-Flüssigkeit auf den Wimpern gleichmäßig zu verteilen, und letztlich muss mit dem Auftragsvorgang eine Separierung der Wimpern einhergehen, um ein Zusammenkleben zu verhindern.On the one hand, such mascara brushes have to have good transfer properties in order to transfer the mascara liquid from a storage container to the user's eyelashes, on the other hand, advantageous application properties have to be provided in order to distribute the transferred mascara liquid evenly on the eyelashes and, finally, with the order process associated with a separation of the eyelashes to prevent sticking together.

Um diese Ziele zu erreichen, sind zahlreiche Lösungen bekannt, wobei einerseits eine gezielte Auswahl des Borstenmaterials, der Borstendicke und der Borstenlänge vor dem Verdrillen der Drahtabschnitte und andererseits verschiedene Techniken des Beschneidens des verdrillten Bürstchens beschrieben werden.In order to achieve these objectives, numerous solutions are known, describing on the one hand a targeted selection of the bristle material, the bristle thickness and the bristle length prior to the twisting of the wire sections, and on the other hand various techniques of trimming the twisted brush.

Aus der US 6 289 902 ist es bekannt, als Draht einen plastisch deformierbaren Draht zu verwenden und die Borsten in bestimmten Winkelsektoren vollständig abzuschneiden oder auf eine einheitlich radiale Länge zu kürzen.From the US 6,289,902 It is known to use as wire a plastically deformable wire and to cut off the bristles in certain angular sectors completely or to shorten to a uniform radial length.

Aus der US 6 279 583 ist eine Herstellungstechnik bekannt, bei welcher die Borsten zwischen den Drahtabschnitten durch teilweises Verdrillen zunächst provisorisch festgelegt, dann beschnitten und schließlich durch weiteres Verdrillen endgültig festgelegt werden. Dies ist herstellungstechnisch aufwendig und ermöglicht keine hohe Produktionsgeschwindigkeit.From the US 6,279,583 a manufacturing technique is known in which the bristles between the wire sections by partially twisting initially provisionally fixed, then trimmed and finally by further Twisting finally be set. This is manufacturing technology consuming and does not allow high production speed.

Die US 6 260 558 B1 beschreibt ein Herstellungsverfahren für ein Mascara-Bürstchen, mit welchem ein Bürstchen geschaffen wird, welches in unterschiedlichen Sektoren unterschiedlich lange Borsten aufweist. Auch dieses Herstellungsverfahren ist außerordentlich aufwendig und für eine wirtschaftliche Massenproduktion nicht geeignet.The US Pat. No. 6,260,558 B1 describes a manufacturing method for a mascara brush, with which a brush is provided, which has different lengths of bristles in different sectors. Also, this manufacturing process is extremely expensive and not suitable for economical mass production.

Die WO 96/311 beschreibt ein Mascara-Bürstchen, welches bezüglich seiner Längsachse Sektoren mit unterschiedlich dichten Borsten aufweist, was dadurch erhalten wird, dass der Fachkasten, aus welchem die Borsten beim Verdrillen entnommen werden, unterschiedlich dicht mit Borsten besetzt ist.The WO 96/311 describes a mascara brush which has sectors with differently dense bristles with respect to its longitudinal axis, which is obtained by the fact that the compartment box, from which the bristles are taken during the twisting, is filled with different densities with bristles.

Aus DE 37 35 963 D2 ist es bekannt, das fertige Bürstchen so zu beschneiden, dass zur Verbesserung der Kämmwirkung Kammbereiche entstehen.Out DE 37 35 963 D2 It is known to trim the finished brush so that comb areas arise to improve the combing effect.

Aus EP 1 129 641 A2 ist es bekannt, Borsten unterschiedlichen Materials in Längsrichtung des Bürstchens gesehen mit unterschiedlicher Dichte zu verarbeiten.Out EP 1 129 641 A2 It is known to process bristles of different material seen in the longitudinal direction of the brush with different density.

Die EP 0 832 580 A1 beschreibt ein Mascara-Bürstchen, bei welchem in einem ersten Schneidvorgang eine ballige, zigarrenartige Grundform hergestellt wird und durch einen zweiten Schneidvorgang dann in Längsrichtung verlaufende Ausfräsungen.The EP 0 832 580 A1 describes a mascara brush, in which in a first cutting a crowned, cigar-like basic shape is produced and then by a second cutting operation in the longitudinal direction milling.

Aus EP 1 000 566 A2 ist ein Mascara-Bürstchen bekannt, dessen Mantelfläche im Querschnitt im wesentlichen quadratisch beschnitten ist.Out EP 1 000 566 A2 is a mascara brush known whose lateral surface is cut in cross section substantially square.

Ausgehend von diesen bekannten Lösungen liegt der Erfindung die Aufgabe zugrunde, ein Mascara-Bürstchen zu schaffen, welches optimal an die Grundanforderungen eines solchen Bürstchens ebenso wie an die subjektiven Wünsche der Verbraucherin anpassbar ist.Based on these known solutions, the invention has for its object to provide a mascara brush, which is optimally adapted to the basic requirements of such a brush as well as the subjective wishes of the consumer.

Diese Aufgabe wird mit den Merkmalen des kennzeichnenden Teils der Ansprüche 1 und 7 gelöst.This object is achieved with the features of the characterizing part of claims 1 and 7.

Vorzugsweise ist vorgesehen, dass die Spitzen der kürzeren Borsten auch jeweils auf einer Parallelen zu den verdrillten Drahtabschnitten liegen.It is preferably provided that the tips of the shorter bristles also lie on a parallel to the twisted wire sections.

Erfindungsgemäß wird eine mit einer konventionellen Herstellungstechnik hergestellte Bürste beim zweiten Schneidvorgang also nicht so beschnitten, dass die Borsten in bestimmten Zonen, sei es gesehen in Umfangsrichtung oder in Längsrichtung, vollständig abgeschnitten bzw. verkürzt werden, sondern es wird lediglich ein Ausdünnungsschnitt derart vorgenommen, dass jeweils nur ein Teil der Borsten gekürzt wird, wobei die längeren Borsten aufgrund ihrer Aufspreizung von der Drahtseele weg mit ihren Spitzen eine weitgehend gleichmäßige erste, äußere Hüllkurve bilden.According to the invention, a brush produced by a conventional manufacturing technique is therefore not so trimmed in the second cutting process that the bristles are completely cut or shortened in certain zones, as seen in the circumferential direction or in the longitudinal direction, but only a thinning cut is made such that in each case only a portion of the bristles is shortened, wherein the longer bristles form a largely uniform first outer envelope due to their spreading away from the wire core with their tips.

Indem man erfindungsgemäß Bereiche mit einer reduzierten Anzahl von Faserspitzen erzeugt, ohne die gesamte Faseranzahl in der Bürste pro Windung zu reduzieren, ist es in Anpassung an den jeweiligen Typ von Verbraucherinnen möglich, dort gezielt ein erhöhtes Massedepot zu erreichen.By producing areas with a reduced number of fiber tips in accordance with the invention without reducing the total number of fibers in the brush per turn, it is possible, in adaptation to the respective type of consumers, to specifically achieve an increased mass depot there.

Zur Durchführung des zweiten Schnitts werden erfindungsgemäß also keine rotierenden Schneidwerkzeuge verwendet bzw. das Bürstchen rotierend beschnitten, da sonst in den beschnittenen Bereichen alle Fasern gleichmäßig gekürzt würden, wie dies aus dem Stand der Technik bekannt ist.In order to carry out the second cut, therefore, according to the invention, no rotating cutting tools are used or the brush is rotationally trimmed, since otherwise all fibers would be uniformly shortened in the trimmed areas, as is known from the prior art.

Vorzugsweise kann zweite, innere die Hüllkurve der kürzeren Borsten so ausgestaltet sein, dass sich in verhältnismäßig dichter Folge beschnittene und unbeschnittene Bereiche abwechseln, d. h. die Hüllkurve weist eine kammartige Struktur auf. Günstigerweise liegt die Breite der beim zweiten Schnitt beschnittenen Bereiche zwischen 0,6 und 2,8 mm, insbesondere bei 1,2 mm, und die Breite der nicht beschnittenen Bereiche zwischen 0,4 und 3 mm, insbesondere bei 0,8 mm.Preferably, the second, inner envelope of the shorter bristles may be configured to alternate in relatively close sequence with trimmed and uncut portions, i. H. the envelope has a comb-like structure. Conveniently, the width of the trimmed at the second section ranges between 0.6 and 2.8 mm, in particular 1.2 mm, and the width of the uncut areas between 0.4 and 3 mm, in particular at 0.8 mm.

Die zweite, innere Hüllkurve der kürzeren Borsten kann sich nur über einen zentralen Bereich des Bürstchens oder alternativ über beide Endbereiche erstrecken. Weiterhin ist es möglich, dass der zweite Schnitt nur auf einer Seite des Bürstchens angebracht wird.The second, inner envelope of the shorter bristles may extend only over a central portion of the brush or alternatively over both end portions. Furthermore, it is possible that the second cut is applied only on one side of the brush.

Die zweite, innere Hüllkurve kann im Querschnitt rechteckig oder dreieckig ausgebildet sein, wobei die Mittellängsachse der Hüllkurve mit den verdrillten Drahtabschnitten zusammenfallen oder gegen diese versetzt sein kann.The second, inner envelope may be rectangular or triangular in cross-section, wherein the central longitudinal axis of the envelope coincide with the twisted wire sections or may be offset therefrom.

Die erste äußere Hüllkurve kann alle bekannten Geometrien aufweisen, also insbesondere zylindrisch, konisch, ballig, konkav oder eine Kombination dieser Grundformen.The first outer envelope may have all known geometries, ie in particular cylindrical, conical, spherical, concave or a combination of these basic shapes.

In Fig. 1 ist ein herkömmliches Mascara-Bürstchen 1 dargestellt, bei welchem eine Mehrzahl von Borsten 2 zwischen zwei verdrillten Drahtabschnitten 3, 4 festgelegt ist. Durch einen ersten Schnitt sind die Borsten 2 so zugeschnitten, dass deren Spitzen eine erste zylinderförmige äußere Hüllkurve 5 ausbilden, welche zum äußeren Ende 6 hin konisch zuläuft.In Fig. 1 a conventional mascara brush 1 is shown in which a plurality of bristles 2 between two twisted wire sections 3, 4 is fixed. By a first cut, the bristles 2 are cut so that their tips form a first cylindrical outer envelope 5, which tapers towards the outer end 6 out.

Ausgehend von einem solchen an sich bekannten Bürstchen findet erfindungsgemäß ein zweiter Schnitt derart statt, dass die Spitzen der durch einen solchen zweiten Schnitt verkürzten Borsten auf einer zweiten, inneren Hüllkurve 7 liegen, wobei die Spitzen 8 der kürzeren Borsten 9 auf einer Orthogonalen liegen, welche in einem Abstand A zur Mittellängsachse des Bürstchens verläuft.Starting from such a brush known per se according to the invention, a second cut takes place such that the tips of the shortened by such a second cut bristles on a second, inner envelope 7, wherein the tips 8 of the shorter bristles 9 lie on an orthogonal, which extends at a distance A to the central longitudinal axis of the brush.

Bei der Ausführungsform nach Fig. 2 erstreckt sich der zweite Schnitt über die gesamte Länge des Bürstchens 1, bei der Ausführungsform nach Fig. 3 über einen zentralen Abschnitt 10 und bei der Ausführungsform nach Fig. 4 über außenliegende Abschnitte 11 und 12.In the embodiment according to Fig. 2 the second section extends over the entire length of the brush 1, in the embodiment according to Fig. 3 via a central portion 10 and in the embodiment according to Fig. 4 over outer sections 11 and 12.

Bei den Ausführungsformen nach Fig. 5 bis 7 ist jeweils für den zweiten Schnitt nur eine einzige Schnittebene vorgesehen, die dementsprechend die zweite, innere Hüllkurve 7 bildet und einen unterschiedlichen Abstand A zu der durch die verdrillten Drähte 3, 4 gebildeten Ziele des Bürstchens aufweist.According to the embodiments Fig. 5 to 7 For example, only a single cutting plane is provided for the second cut, which accordingly forms the second, inner envelope 7 and has a different distance A from the brush target formed by the twisted wires 3, 4.

Bei den Ausführungsformen nach Fig. 8 bis 13 sind jeweils mehrere Schnittebenen für den jeweils zweiten Schnitt zur Ausdünnung der Borstendichte vorgesehen.According to the embodiments Fig. 8 to 13 In each case several cutting planes are provided for the respective second cut for thinning the bristle density.

Bei der Ausführungsform nach Fig. 8 verlaufen die Schnittebenen und dementsprechend Hüllkurven 5 parallel zueinander und im gleichen Abstand zu den verdrillten Drähten 3, 4.In the embodiment according to Fig. 8 The cutting planes and accordingly envelopes 5 run parallel to one another and at the same distance from the twisted wires 3, 4.

Bei der Ausführungsform nach Fig. 9 wird das erste Bürstchen nach Erstellung der ersten Schnittebene um 120° gedreht, erneut flächig beschnitten und wiederum um 120° gedreht und flächig beschnitten.In the embodiment according to Fig. 9 The first brush is rotated after creation of the first cutting plane by 120 °, trimmed again flat and again rotated by 120 ° and cropped flat.

Bei der Ausführungsform nach Fig. 10 wird das Bürstchen nach jedem Schnitt um 90° gedreht, so dass ein quadratischer Querschnitt der inneren Hüllkurve 7 entsteht.In the embodiment according to Fig. 10 The brush is rotated by 90 ° after each cut, so that a square cross section of the inner envelope 7 is formed.

Die Ausführungsform nach Fig. 11 ist eine Modifikation der Ausführungsform nach Fig. 10, bei welcher die längeren Borsten nicht, wie gemäß Fig. 8 bis 10 zylinderförmig, sondern im Querschnitt quadratisch beschnitten sind.The embodiment according to Fig. 11 is a modification of the embodiment according to Fig. 10 in which the longer bristles do not, as in Fig. 8 to 10 cylindrical, but are truncated in cross section square.

Bei der Ausführungsform nach Fig. 12 ist die äußere Hüllkurve 5 im Querschnitt dreieckig und die innere Hüllkurve 7 ebenfalls dreieckig beschnitten, wobei die Spitzen der beiden Dreiecke in entgegengesetzte Richtungen weisen.In the embodiment according to Fig. 12 the outer envelope 5 is triangular in cross-section and the inner envelope 7 is also truncated triangular, with the tips of the two triangles facing in opposite directions.

Bei der Version nach Fig. 13 sind zwei zueinander parallele Seitenflächen vorgesehen, die über abgerundete Bereiche verbunden sind.In the version after Fig. 13 two parallel side surfaces are provided, which are connected via rounded areas.
