  • the finger support is integrally connected to the proximal and distal end parts.
  • the finger support consists of two, preferably at least three, leaf spring elements grouped eccentrically, but symmetrically to one another around the free applicator center. This means that the applicator center is not filled with material, but is in fact free.
  • the leaf spring elements have fingers on their outside.
  • the applicator tip and the handle attachment are connected exclusively via the leaf spring elements.
  • the leaf spring elements are elastic in such a way that the applicator tip can be deflected by at least 5 mm in the radial direction under the influence of a force acting on one side in the radial direction between 0.1 N and 1 N without one of the leaf spring elements crumpling or buckling, i.e. collapsing.
  • Each of the leaf spring elements thus deforms elastically, but retains its cross-sectional shape as such.
  • the cross section of the leaf spring elements in the direction perpendicular to the longitudinal axis L of the applicator has the shape of a triangle which is oriented such that the triangle with a point comes closest to the center of the applicator.
  • Shows the cross-section has the shape of such a triangle, this has the decisive advantage that the leaf spring element as such always remains dimensionally stable. This means that the leaf spring element can indeed deform, but no uncontrolled collapse of the leaf spring element can occur.
  • the leaf spring element is also sufficiently flexible, because it is very slim on its inside due to the tip present there and therefore only opposes a bending in the radial direction with a reduced geometrical moment of inertia.
  • a leaf spring element designed in this way has as large an area as possible for fastening bristles on its outer surface located on the outer circumference. Because of this, each leaf spring element can carry a bristle facing which is demanding from an application point of view and which consists of more than just one row of bristles.
  • each leaf spring element which run in the radial direction, are preferably flat when viewed in the radial direction. This makes it much easier to shape the applicator, since the movable cores that define the free spaces between the leaf spring elements are particularly easy to pull.
  • each leaf spring element is curved convexly outward on its radially outer surface in the direction of the longitudinal axis of the applicator. This results in an advantageous course of the leaf spring elements and the bristle facing they carry, so that the bristle facing can be applied particularly sensitively.

  • Such an arrangement not only gives the leaf spring elements a large amount of freedom of movement. Rather, such an arrangement has the great advantage that a considerable amount of cosmetic mass can be stored in the interior of the applicator between the leaf spring elements, of which at least a noticeable portion can be released by deformation of the applicator and then used during application.
  • leaf spring elements keep a distance from the imaginary longitudinal axis L of the applicator over their entire length or at least over their predominant length.

In the majority of applications, however, it is advantageous if the length of the fingers increases in the direction of the center of the leaf spring elements and, viewed from the center, decreases towards at least one, preferably both ends of the leaf spring elements.
  • the cosmetic applicator preferably consists of at least two different plastic materials.
  • the leaf spring elements each consist at least partially, preferably predominantly, in some cases completely, of a softer or more flexible plastic material than the proximal and distal end parts, which hold the leaf spring elements together at their ends - preferably like a clamp that holds the ends of the leaf spring elements firmly together .
  • the applicator consists of a one-piece, single-material base part made of plastic.
  • This base part can in turn consist of the proximal and distal end parts and in each case at least one section of the later leaf spring elements.

Description

Die Erfindung betrifft einen Applikator nach dem Oberbegriff des Anspruchs 1.The invention relates to an applicator according to the preamble of claim 1.

TECHNISCHER HINTERGRUNDTECHNICAL BACKGROUND

Insbesondere bei Kosmetikapplikatoren besteht ein großes Bedürfnis danach, die Beladung des Borstenbesatzes mit dem Kosmetikum in einem weiten Bereich steuern zu können.In the case of cosmetic applicators in particular, there is a great need to be able to control the loading of the bristle set with the cosmetic over a wide range.

Um eine solche Steuerung zu erreichen, wird meistens am Borstenbesatz als solchem angesetzt. Es werden unterschiedlich lange Borsten, eine lokal unterschiedliche Dichte des Borstenbesatzes vorgesehen oder der Borstenbesatz erhält durch nachgängiges Beschneiden oder Beschleifen einen bestimmten Trimm.In order to achieve such a control, the bristle facing is usually used as such. There are bristles of different lengths, a locally different density of the bristle facing or the bristle facing is given a specific trim by subsequent trimming or grinding.

Auch darüber hinaus ist schon ein Ansatz vorgeschlagen worden. So sind aus der DE 202014102875 bereits Applikatoren bekannt, die Flügel besitzen, von denen Borsten abstehen. Die Flügel sind mit einem Filmscharnier schwenkbar an einem zentralen Kern gelagert und können sich bei entsprechendem Druck auf den Flügel dichter an den Kern anlenken, indem sie um das Filmscharnier klappen und auf den Kern zu schwenken.A further approach has already been proposed. So are from the DE 202014102875 already known applicators that have wings from which bristles protrude. The wings are pivotably mounted on a central core by means of a film hinge and, when the pressure on the wing is appropriate, can be articulated closer to the core by folding around the film hinge and pivoting onto the core.

Diese Flügel haben in der Praxis nicht selten den Nachteil, dass sich ihre genaue Position nicht festlegen lässt. In nicht wenigen Fällen stehen die Flügel im Neuzustand weiter vom Kern des Applikators ab als nach längerer Zeit des Gebrauchs. Das bedeutet nichts anderes, als dass sich die geometrische Gestalt des Applikators und damit sein Auftragsverhalten nicht genau und dauerhaft definieren lassen. Es sind also gewisse Abstriche in Bezug auf die Wiederholgenauigkeit des Auftragsverhaltens zu machen. Weitere Kosmetikapplikatoren sind beispielsweise aus den Druckschriften WO 2010/135052 A2 , FR 2056 581 A1 , WO2012/085398 A2 , EP 1 593 320 A1 oder FR 2 982 466 A1 bekannt.In practice, these wings often have the disadvantage that their exact position cannot be determined. In not a few cases, the wings protrude further from the core of the applicator when new than after a longer period of use. That means nothing else than that the geometric Do not allow the shape of the applicator and thus its application behavior to be precisely and permanently defined. So there are certain compromises to be made with regard to the repeatability of the order behavior. Further cosmetic applicators are, for example, from the publications WO 2010/135052 A2 , FR 2056 581 A1 , WO2012 / 085398 A2 , EP 1 593 320 A1 or FR 2 982 466 A1 known.

DAS DER ERFINDUNG ZUGRUNDE LIEGENDE PROBLEMTHE PROBLEM UNDERLYING THE INVENTION

Dieses Problem wird durch die Bereitstellung eines Kosmetikapplikators gemäß Anspruch 1 gelöst. Demgegenüber besteht Bedarf an einem Applikator, dessen Beladung sich einerseits recht gut dadurch variieren lässt, dass er schräg oder mit seitlichem Druck durch den Applikator hindurchgezogen wird, und der andererseits aber stets, auch nach geraumer Gebrauchszeit, immer noch seine von Anfang an vordefinierte geometrische Gestalt besitzt und mit dem vorzugsweise auch nicht unerhebliche Kräfte aufgebracht werden können, ohne den Applikator unkontrolliert zu verformen, etwa beim Kämmen oder Curlen des Haaransatzes bzw. der Wimpern.This problem is solved by providing a cosmetic applicator according to claim 1. On the other hand, there is a need for an applicator whose load can be varied quite well by being pulled through the applicator at an angle or with lateral pressure, and which, on the other hand, always retains its predefined geometric shape, even after a long period of use possesses and with which preferably not inconsiderable forces can be applied without deforming the applicator in an uncontrolled manner, for example when combing or curling the hairline or the eyelashes.

DIE ERFINDUNGSGEMÄSSE LÖSUNG (HAUPTASPEKTE)THE SOLUTION ACCORDING TO THE INVENTION (MAIN ASPECTS)

Erfindungsgemäß wird ein Kosmetikapplikator mit einem sich entlang einer das gedachte Applikatorzentrum bildenden Längsachse erstreckenden Fingerträger vorgeschlagen. Der Fingerträger erstreckt sich zwischen einer Applikatorspitze, die bevorzugt den distalen Endteil bildet, und einem Stielabschnitt, der bevorzugt den proximalen Endteil bildet. Die Applikatorspitze ist undurchbrochen und bildet vorzugsweise ein im Wesentlichen oder besser vollständig zylindrisches Element. Der Fingerträger ist einstückig mit dem proximalen und dem distalen Endteil verbunden. Erfindungsgemäß besteht der Fingerträger aus zwei, besser mindestens drei exzentrisch, aber zueinander symmetrisch um das freie Applikatorzentrum herumgruppierten Blattfederelementen. Das bedeutet, dass das Applikatorzentrum nicht durch Material ausgefüllt ist, sondern in der Tat frei ist. Die Blattfederelemente tragen auf ihrer Außenseite Finger. Dabei sind die Applikatorspitze und der Stielansatz ausschließlich über die Blattfederelemente verbunden. Die Blattfederelemente sind derart elastisch, dass die Applikatorspitze unter dem Einfluss einer einseitig in radialer Richtung wirkenden Kraft zwischen 0,1 N und 1 N um mindestens 5 mm in radialer Richtung ausgelenkt werden kann, ohne dass eines der Blattfederelemente knautscht oder beult, d. h. zusammenklappt. Jedes der Blattfederelemente verformt sich also elastisch, behält aber seine Querschnittsform als solche bei.According to the invention, a cosmetic applicator is proposed with a finger support extending along a longitudinal axis forming the imaginary applicator center. The finger support extends between an applicator tip, which preferably forms the distal end part, and a stem section, which preferably forms the proximal end part. The applicator tip is uninterrupted and preferably forms a substantially or better completely cylindrical element. The finger support is integrally connected to the proximal and distal end parts. According to the invention, the finger support consists of two, preferably at least three, leaf spring elements grouped eccentrically, but symmetrically to one another around the free applicator center. This means that the applicator center is not filled with material, but is in fact free. The leaf spring elements have fingers on their outside. The applicator tip and the handle attachment are connected exclusively via the leaf spring elements. The leaf spring elements are elastic in such a way that the applicator tip can be deflected by at least 5 mm in the radial direction under the influence of a force acting on one side in the radial direction between 0.1 N and 1 N without one of the leaf spring elements crumpling or buckling, i.e. collapsing. Each of the leaf spring elements thus deforms elastically, but retains its cross-sectional shape as such.

Erfindungsgemäß weist der Querschnitt der Blattfederelemente in Richtung senkrecht zur Längsachse L des Applikators die Gestalt eines Dreiecks auf, das so ausgerichtet ist, dass das Dreieck mit einer Spitze dem Applikatorzentrum am nächsten kommt. Zeigt der Querschnitt die Form eines derartigen Dreiecks, so hat das den entscheidenden Vorteil, dass das Blattfederelement als solches immer formstabil bleibt. Das bedeutet, dass sich das Blattfederelement zwar verformen kann, aber kein unkontrolliertes Kollabieren des Blattfederelements eintreten kann. Gleichzeitig ist das Blattfederelement aber auch hinreichend nachgiebig, denn es ist auf seiner Innenseite aufgrund der dort vorhandenen Spitze sehr schlank und setzt daher einer Biegung in radialer Richtung nur ein verringertes Flächenträgheitsmoment entgegen. Andererseits weist ein so gestaltetes Blattfederelement auf seiner am Außenumfang liegenden Außenfläche eine möglichst große Fläche zur Befestigung von Borsten auf. Aufgrund dessen kann jedes Blattfederelement einen unter Anwendungsgesichtspunkten anspruchsvollen Borstenbesatz tragen, der aus mehr als nur einer Borstenreihe besteht.According to the invention, the cross section of the leaf spring elements in the direction perpendicular to the longitudinal axis L of the applicator has the shape of a triangle which is oriented such that the triangle with a point comes closest to the center of the applicator. Shows the cross-section has the shape of such a triangle, this has the decisive advantage that the leaf spring element as such always remains dimensionally stable. This means that the leaf spring element can indeed deform, but no uncontrolled collapse of the leaf spring element can occur. At the same time, however, the leaf spring element is also sufficiently flexible, because it is very slim on its inside due to the tip present there and therefore only opposes a bending in the radial direction with a reduced geometrical moment of inertia. On the other hand, a leaf spring element designed in this way has as large an area as possible for fastening bristles on its outer surface located on the outer circumference. Because of this, each leaf spring element can carry a bristle facing which is demanding from an application point of view and which consists of more than just one row of bristles.

BEVORZUGTE AUSGESTALTUNGSMÖGLICHKEITENPREFERRED DESIGN POSSIBILITIES

Vorzugsweise sind die in radialer Richtung verlaufenden Flankenoberflächen jedes Blattfederelements in radialer Richtung gesehen eben. Das erleichtert das Ausformen des Applikators ungemein, da sich die beweglichen Kerne, die die Freiräume zwischen den Blattfederelementen definieren, besonders einfach ziehen lassen.The flank surfaces of each leaf spring element, which run in the radial direction, are preferably flat when viewed in the radial direction. This makes it much easier to shape the applicator, since the movable cores that define the free spaces between the leaf spring elements are particularly easy to pull.

Günstig ist es, wenn jedes Blattfederelement an seiner radial außenliegenden Oberfläche in Richtung der Applikatorlängsachse konvex nach außen gekrümmt ist. Auf diese Art und Weise ergibt sich ein vorteilhafter Verlauf der Blattfederelemente und des von ihnen getragenen Borstenbesatzes, sodass sich mit dem Borstenbesatz besonders feinfühlig applizieren lässt.It is advantageous if each leaf spring element is curved convexly outward on its radially outer surface in the direction of the longitudinal axis of the applicator. This results in an advantageous course of the leaf spring elements and the bristle facing they carry, so that the bristle facing can be applied particularly sensitively.

Besonders günstig ist bei alledem, wenn jedes Blattfederelement an seiner radial außenliegenden Oberfläche in Umfangsrichtung nach außen konvex gekrümmt ist. Hierdurch ergibt sich ein besonders gutes Auftragsverhalten des Applikators, wenn mit diesem bei der Applikation leichte Drehbewegungen um die Applikatorlängsachse L herum ausgeführt werden.In all of this, it is particularly favorable if each leaf spring element is located on its radially outer surface is convexly curved in the circumferential direction outward. This results in a particularly good application behavior of the applicator if it is used to perform slight rotary movements around the longitudinal axis L of the applicator during application.

Idealerweise macht der materialfreie Raum innerhalb der Hüllkurve um die borstentragende Oberfläche der Blattfederelemente herum mindestens 20 %, besser mindestens 30 % und im Idealfall mindestens 40 % des von der Hüllkurve umschlossenen Raums aus. Die gedachte Hüllkurve ist diejenige Kurve bzw. derjenige gedachte Körper, der das Arrangement der Blattfederelemente durch Anschmiegen an deren Außenoberfläche am engsten umschließt, wenn man sich die Borsten wegdenkt - also gedanklich davon ausgeht, dass die Blattfederelemente keine Borsten tragen.Ideally, the material-free space within the envelope around the bristle-bearing surface of the leaf spring elements makes up at least 20%, better at least 30% and ideally at least 40% of the space enclosed by the envelope. The imaginary envelope curve is that curve or the imaginary body that most closely surrounds the arrangement of the leaf spring elements by nestling against their outer surface, if one imagines the bristles away - that is, it is assumed that the leaf spring elements do not have any bristles.

Eine solche Anordnung verleiht nicht nur den Blattfederelementen einen großen Bewegungsspielraum. Eine solche Anordnung hat vielmehr den großen Vorteil, dass im Inneren des Applikators zwischen den Blattfederelementen eine beträchtliche Menge an Kosmetikmasse gespeichert werden kann, von der zumindest ein spürbarer Anteil durch Verformung des Applikators freisetzbar und anschließend bei der Applikation nutzbar ist.Such an arrangement not only gives the leaf spring elements a large amount of freedom of movement. Rather, such an arrangement has the great advantage that a considerable amount of cosmetic mass can be stored in the interior of the applicator between the leaf spring elements, of which at least a noticeable portion can be released by deformation of the applicator and then used during application.

Besonders günstig ist es dabei, wenn die Blattfederelemente auf gesamter Länge oder zumindest auf ihrer überwiegenden Länge Abstand von der gedachten Längsachse L des Applikators halten.It is particularly favorable if the leaf spring elements keep a distance from the imaginary longitudinal axis L of the applicator over their entire length or at least over their predominant length.

Im Rahmen einer bevorzugten Ausführungsform ist vorgesehen, dass jedes der Blattfederelemente mehrere Reihen aus jeweils in einer Flucht in Richtung der Längsachse hintereinanderstehenden Fingern umfasst. Hierdurch wird jedes Blattfederelement dazu ertüchtigt, als eigenständiges Auftragselement zu fungieren.In the context of a preferred embodiment it is provided that each of the leaf spring elements comprises a plurality of rows of fingers each in alignment in the direction of the longitudinal axis. This will make every Leaf spring element enabled to function as an independent application element.

Es kann sinnvoll sein, benachbarte Blattfederelemente mit unterschiedlichen Besatzdichten oder Besatzmustern zu versehen.It can make sense to provide adjacent leaf spring elements with different fill densities or fill patterns.

Idealerweise sind alle Blattfederelemente unterschiedlich besetzt. Auf diese Art und Weise kann der Benutzer leicht variieren.Ideally, all leaf spring elements are occupied differently. In this way the user can vary slightly.

Bei einem mit drei Blattfederelementen ausgestatteten Applikator kann er so durch Drehung um jeweils 120° einen anders gestalteten Besatz zum Einsatz bringen und dadurch sehr unterschiedliche Ergebnisse erzielen.In the case of an applicator equipped with three leaf spring elements, by rotating it through 120 ° in each case, it can use a differently designed trim and thus achieve very different results.

Damit aber nicht genug. Der erfindungsgemäße Applikator bietet für den kreativen Einsatz aber noch wichtige weitere Variationsmöglichkeiten. Denn die Anwenderin kann sich hier das sehr unterschiedliche Abstreifverhalten zu Nutze machen: Zieht sie den erfindungsgemäßen Applikator leicht schräg und/oder mit Druck zu einer Seite hin so durch den Abstreifer, dass das Blattfederelement, das den dichtesten Borstenbesatz trägt, am innigsten mit der Abstreiferlippe in Kontakt kommt, dann erhält sie ein deutlich anderes Abstreif- und Applikationsergebnis, als wenn sie den erfindungsgemäßen Applikator so durch den Abstreifer zieht, dass das Blattfederelement, das den lichtesten Borstenbesatz trägt, am innigsten mit der Abstreiferlippe in Kontakt kommt. Der erfindungsgemäße Applikator zeichnet sich also dadurch aus, dass er in besonders hohem Maß die Kreativität begünstigt.But that's not all. The applicator according to the invention offers other important variation possibilities for creative use. Because the user can make use of the very different wiping behavior here: If she pulls the applicator according to the invention at a slight angle and / or with pressure to one side through the wiper so that the leaf spring element, which has the densest bristle facing, is closest to the wiper lip comes into contact, then it receives a significantly different wiping and application result than when it pulls the applicator according to the invention through the wiper in such a way that the leaf spring element, which has the lightest bristle facing, comes into closest contact with the wiper lip. The applicator according to the invention is thus characterized in that it promotes creativity to a particularly high degree.

Als besonders günstig hat es sich erwiesen, wenn die Finger einer Reihe zumindest überwiegend jeweils auf der Höhe der Mitte des Zwischenraums zwischen zwei unmittelbar aufeinanderfolgenden Fingern der unmittelbar benachbarten Reihe angeordnet sind. Auf diese Art und Weise ergibt sich ein Borstenbesatz, der sich auch bei signifikanter elastischer Verformung der Blattfederelemente besonders homogen verhält.It has proven to be particularly favorable if the fingers of a row are at least predominantly in each case directly at the level of the middle of the space between two successive fingers of the immediately adjacent row are arranged. This results in a set of bristles which behaves particularly homogeneously even with significant elastic deformation of the leaf spring elements.

In manchen Fällen ist es besonders vorteilhaft, wenn die Länge der einzelnen Finger 7 der Blattfederelemente überall die gleiche ist. In der überwiegenden Zahl der Anwendungsfälle ist es hingegen vorteilhaft, wenn die Länge der Finger in Richtung der Mitte der Blattfederelemente zunimmt und, von der Mitte aus gesehen, zu mindestens einem, vorzugsweise beiden Enden der Blattfederelemente hin abnimmt.In some cases it is particularly advantageous if the length of the individual fingers 7 of the leaf spring elements is the same everywhere. In the majority of applications, however, it is advantageous if the length of the fingers increases in the direction of the center of the leaf spring elements and, viewed from the center, decreases towards at least one, preferably both ends of the leaf spring elements.

Um das Flexibilitätsverhalten des Kosmetikapplikators besonders vorteilhaft zu beeinflussen, besteht der Kosmetikapplikator vorzugsweise aus mindestens zwei unterschiedlichen Kunststoffmaterialien. Im Idealfall bestehen die Blattfederelemente jeweils zumindest teilweise, bevorzugt überwiegend, in manchen Fällen vollständig aus einem weicheren oder flexibleren Kunststoffmaterial als der proximale und der distale Endteil, die die Blattfederelemente an ihren Enden zusammenhalten - vorzugsweise wie eine Zwinge, die die Enden der Blattfederelemente fest zusammenhält.In order to influence the flexibility behavior of the cosmetic applicator in a particularly advantageous manner, the cosmetic applicator preferably consists of at least two different plastic materials. Ideally, the leaf spring elements each consist at least partially, preferably predominantly, in some cases completely, of a softer or more flexible plastic material than the proximal and distal end parts, which hold the leaf spring elements together at their ends - preferably like a clamp that holds the ends of the leaf spring elements firmly together .

Idealerweise besteht der Applikator aus einem einstückig und einstofflich aus Kunststoff bestehenden Basisteil. Dieses Basisteil kann seinerseits aus dem proximalen und distalen Endteil bestehen und jeweils zumindest einem Abschnitt der späteren Blattfederelemente. Der besagte Abschnitt verbindet im Regelfall bereits das proximale und das distale Endteil einstückig und einstofflich. Auf das so hergestellte Basisteil bzw. dessen Abschnitte, die zu den späteren Blattfederelementen gehören, kann eine aus einem anderen Kunststoff bestehende Schicht auf- oder angespritzt sein, die die Finger ausbildet.Ideally, the applicator consists of a one-piece, single-material base part made of plastic. This base part can in turn consist of the proximal and distal end parts and in each case at least one section of the later leaf spring elements. As a rule, said section already connects the proximal and distal end parts in one piece and in one material. A layer consisting of another plastic, which forms the fingers, can be molded or molded onto the base part produced in this way or its sections, which belong to the later leaf spring elements.

Idealerweise bildet die Applikatorspitze nicht nur die Zwinge für die Blattfederelemente, sondern auch einen massiven Auftragsabschnitt, der vorzugsweise nicht mit Borsten besetzt ist. Besonders günstig ist es hier, wenn die Applikatorspitze eine Kugelkalotte, eine Ellipsenkalotte oder eine Hälfte einer senkrecht zu ihrer Längsachse geschnittenen Erdnussschale ausbildet.Ideally, the applicator tip not only forms the clamp for the leaf spring elements, but also a solid application section, which is preferably not covered with bristles. It is particularly favorable here if the applicator tip forms a spherical cap, an elliptical cap or one half of a peanut shell cut perpendicular to its longitudinal axis.

AUSFÜHRUNGSBEISPIELEEXEMPLARY EMBODIMENTS ERSTES AUSFÜHRUNGSBEISPIELFIRST EXAMPLE

Die Figuren 1 und 2 zeigen ein erstes Ausführungsbeispiel.The Figures 1 and 2 show a first embodiment.

Der Applikator als ganzerThe applicator as a whole

Der Applikator 1 besteht aus einem distalen Endteil 2 und einem proximalen Endteil 3. Das proximale Endteil 3 ist vorzugsweise als Kupplung 8 zum unmittelbaren Ankuppeln des Applikators an einen Stiel oder zum unmittelbaren Ankuppeln des Applikators an einen Griff, insbesondere an einen Griff, der einen Verschluss ausbildet.The applicator 1 consists of a distal end part 2 and a proximal end part 3. The proximal end part 3 is preferably designed as a coupling 8 for directly coupling the applicator to a handle or for directly coupling the applicator to a handle, in particular to a handle that has a lock trains.

Das proximale Endteil und das distale Endteil sind erfindungsgemäß ausschließlich durch die Blattfederelemente 4 miteinander verbunden. Wie man anhand der Figuren sieht, bedeutet das, dass keine sich entlang der zentralen Längsachse des Applikators erstreckende Stange und kein sich entlang der zentralen Längsachse des Applikators erstreckender Kern vorhanden sind, der das proximale Endteil 3 und das distale Endteil 2 miteinander verbindet. Stattdessen ist der erfindungsgemäße Applikator im Regelfall im Bereich der Blattfederelemente entlang der Längsachse L "hohl".According to the invention, the proximal end part and the distal end part are connected to one another exclusively by the leaf spring elements 4. As can be seen from the figures, this means that there is no rod extending along the central longitudinal axis of the applicator and no core extending along the central longitudinal axis of the applicator, which connects the proximal end part 3 and the distal end part 2 to one another. Instead, the applicator according to the invention is as a rule “hollow” in the area of the leaf spring elements along the longitudinal axis L.

Besonders bevorzugt ist es, wenn das proximale Endteil und das distale Endteil in Richtung der Längsachse L jeweils eine Erstreckung zwischen 3 mm und 8 mm, besser nur 6 mm aufweisen.It is particularly preferred if the proximal end part and the distal end part each have an extension between 3 mm and 8 mm, better just 6 mm, in the direction of the longitudinal axis L.

Wie man anhand der Figuren sieht, kann die freie Stirnseite des distalen Endteils eine ebene Fläche sein. Stattdessen kann hier aber auch eine Verrundung vorgesehen sein, etwa in Gestalt einer Kugelkalotte, einer Ellipsenkalotte oder einer halben Erdnuss. Dabei kann es in manchen Fällen auch günstig sein, diese Verrundung als zusätzliche Auftragsfläche ohne Borsten vorzusehen. Hier kann eine Beflockung angebracht sein.As can be seen from the figures, the free end face of the distal end part can be a flat surface. Instead, a rounding can also be provided here, for example in the form of a spherical cap, an elliptical cap or half a peanut. In some cases, it can also be beneficial to provide this rounding as an additional application surface without bristles. Flocking can be attached here.

Die BlattfederelementeThe leaf spring elements

Besonders bevorzugt ist es, wenn die Blattfederelemente 4 in Umfangsrichtung gesehen symmetrisch, d. h. voll-symmetrisch bzw. einem regelmäßigen Muster folgend, angeordnet sind.It is particularly preferred if the leaf spring elements 4 viewed in the circumferential direction symmetrically, ie. H. are arranged fully symmetrically or following a regular pattern.

Die Breite der Blattfederelemente 4 in Umfangsrichtung gesehen ist vorzugsweise über die gesamte Länge der Blattfederelemente 4 (in Richtung der Längsachse L gesehen) konstant. Für besondere Anwendungsfälle kann aber eine in Abhängigkeit von der Position entlang der Längsachse L variierende, unterschiedliche Breite vorliegen. Dabei kann es besonders günstig sein, wenn sich die Breite der Blattfederelemente 4 von ihren Anlenkungspunkten am proximalen Endteil 3 und am distalen Endteil 2 zur Mitte des Blattfederelements 4 hin verringert.The width of the leaf spring elements 4 viewed in the circumferential direction is preferably constant over the entire length of the leaf spring elements 4 (viewed in the direction of the longitudinal axis L). For special applications, however, there may be a different width that varies depending on the position along the longitudinal axis L. It can be particularly advantageous if the width of the leaf spring elements 4 is reduced from their articulation points on the proximal end part 3 and on the distal end part 2 towards the center of the leaf spring element 4.

Sinngemäß Gleiches gilt für die Dicke der Blattfederelemente 4 in radialer Richtung gesehen. Hier ist es vorzugsweise ebenso, dass die Dicke über die gesamte Länge der Blattfederelemente 4 (in Richtung der Längsachse L gesehen) konstant bleibt. Für besondere Anwendungsfälle kann es aber auch hier sinnvoll sein, wenn eine in Abhängigkeit von der Position entlang der Längsachse L unterschiedliche Dicke vorliegt. Es kann dabei besonders günstig sein, wenn sich die Dicke der Blattfederelemente 4 von ihren Anlenkungspunkten am proximalen Endteil 3 und am distalen Endteil 2 zur Mitte des Blattfederelements 4 hin verringert.The same applies analogously to the thickness of the leaf spring elements 4 viewed in the radial direction. Here it is also preferable that the thickness remains constant over the entire length of the leaf spring elements 4 (viewed in the direction of the longitudinal axis L). For special applications, however, it can also be useful here if the thickness is different depending on the position along the longitudinal axis L. It can be particularly advantageous if the thickness of the leaf spring elements 4 is reduced from their articulation points on the proximal end part 3 and on the distal end part 2 towards the center of the leaf spring element 4.

Vorzugsweise jedes der Blattfederelemente trägt einen später noch näher erläuterten Fingerbesatz. Jedes der Blattfederelemente ist in sich flexibel. Die Flexibilität ist derart, dass sich das distale Endteil 2 unter dem Einfluss einer Kraft zwischen 0,1 N und 1 N um einen Weg W von mindestens 10 mm auslenken lässt, so, wie das die Figur 1A zeigt. Auf diese Art und Weise erhält man mithilfe der Blattfederelemente einen in Richtung quer zur Längsachse L besonders flexiblen Applikator. Dessen Beladung lässt sich - in neuartiger Form - dadurch steuern, dass man den Applikator bei Bedarf leicht schräg durch den Abstreifer zieht. Dabei ist das Besondere bei dem Applikator, dass er bei der Applikation formsteif bleibt und daher insbesondere auch gut zum Kämmen eines Haarbesatzes geeignet ist, etwa eines Wimpernbogens.Preferably, each of the leaf spring elements has a finger patch, which will be explained in more detail later. Each of the leaf spring elements is flexible in itself. The flexibility is such that the distal end part 2 can be deflected by a path W of at least 10 mm under the influence of a force between 0.1 N and 1 N, as is the case with the Figure 1A shows. In this way, an applicator which is particularly flexible in the direction transverse to the longitudinal axis L is obtained with the aid of the leaf spring elements. Its loading can be controlled - in a new way - by pulling the applicator slightly at an angle through the scraper if necessary. What is special about the applicator is that it remains dimensionally stable during application and is therefore particularly well suited for combing a set of hair, such as an eyelash arch.

Die Figur 3 zeigt eine weitere Seitenansicht des ersten Ausführungsbeispiels. Die Figur 4 zeigt eine frontale Ansicht eines längs der in Figur 3 eingezeichneten Achse A-A geschnittenen Applikators.The Figure 3 shows a further side view of the first embodiment. The Figure 4 FIG. 13 shows a front view of one along the line in FIG Figure 3 shown axis AA cut applicator.

Hier sieht man sehr gut, welche bevorzugte Querschnittsform die einzelnen Blattfederelemente haben.Here you can see very well which preferred cross-sectional shape the individual leaf spring elements have.

Wie man sieht, sind die Blattfederelemente nicht als Elemente mit einem schalenförmigen Querschnitt ausgestattet, d. h. mit einem Querschnitt, bei dem der radiale Abstand zwischen der Außenoberfläche und der Innenoberfläche zumindest im Wesentlichen überall konstant ist (wenn man die Finger unberücksichtigt lässt) und bei dem die dem Applikatorinneren zugewandte Oberfläche demzufolge konkav ist. Denn ein solcher schalenförmiger Querschnitt mag, wenn er dünnwandig ausgeführt wird, eine sehr gute Elastizität haben. Ein solcher schalenförmiger Querschnitt knickt zu schnell aus, wenn er in radialer Richtung belastet wird, d. h. er kollabiert vorzeitig, woraufhin der Applikator bis zum Ende der Belastung eine undefinierte Gestalt einnimmt.As can be seen, the leaf spring elements are not provided as elements with a cup-shaped cross-section, i. H. with a cross-section in which the radial distance between the outer surface and the inner surface is at least substantially constant everywhere (if the fingers are disregarded) and in which the surface facing the inside of the applicator is consequently concave. Because such a bowl-shaped cross-section, if it is made thin-walled, may have very good elasticity. Such a cup-shaped cross-section buckles too quickly when it is loaded in the radial direction, i. H. it collapses prematurely, whereupon the applicator assumes an undefined shape until the end of the load.

Erfindungsgemäß haben die Blattfederelemente nämlich im Schnitt senkrecht zur Längsachse L eine dreieckige Querschnittsform. Die beiden sich (vollständig bzw. im Wesentlichen) in radialer Richtung erstreckenden Flanken jedes Blattfederelements laufen aufgrund dessen in radial einwärtiger Richtung aufeinander zu. Sie treffen sich an ihrem maximal radial einwärtigen Punkt, der hier Scheitelpunkt 6 genannt wird. Vorzugsweise sind die beiden sich in radialer Richtung erstreckenden Flanken 5 eines Blattfederelements in radialer Richtung gerade und weisen in radialer Richtung daher keine Krümmung auf. Besonders bevorzugt ist es, wenn die sich in radialer Richtung erstreckenden, einander zugewandten Flanken zweier unmittelbar benachbarter Blattfederelemente nicht parallel zueinander verlaufen, sondern so, dass der zwischen ihnen befindliche Abstand in radial einwärtiger Richtung hin zur Längsachse L kleiner wird.According to the invention, the leaf spring elements have a triangular cross-sectional shape in a section perpendicular to the longitudinal axis L. The two flanks each extending (completely or essentially) in the radial direction Because of this, leaf spring elements run towards one another in a radially inward direction. They meet at their maximally radially inward point, which is called vertex 6 here. The two flanks 5 of a leaf spring element extending in the radial direction are preferably straight in the radial direction and therefore have no curvature in the radial direction. It is particularly preferred if the facing flanks of two immediately adjacent leaf spring elements extending in the radial direction do not run parallel to one another, but rather in such a way that the distance between them becomes smaller in the radially inward direction towards the longitudinal axis L.

Die umfangsseitige Oberfläche des Blattfederelements 4 weist in Umfangsrichtung gesehen bevorzugt eine konvexe Gestalt auf, ist also nach innen hin, zur Längsachse L gekrümmt. Gewöhnlich weist die umfangsseitige Oberfläche des Blattfederelements 4 zugleich in Richtung entlang der Längsachse L gesehen ebenfalls eine konvexe Gestalt auf. Hierdurch ergibt sich ein besonders günstiges elastisches Verformungsverhalten. Absolut zwingend ist diese vorteilhafte Ausgestaltung aber nicht. Für besondere Anwendungsfälle können die Blattfederelemente auch V-förmig nach außen oder innen gefaltet ausgebildet sein oder die umfangsseitige Oberfläche eines Blattfederelements weist in Richtung parallel zur Längsachse des Applikators eine konkave Krümmung auf.The circumferential surface of the leaf spring element 4, viewed in the circumferential direction, preferably has a convex shape, that is to say it is curved inward toward the longitudinal axis L. Usually, the circumferential surface of the leaf spring element 4 also has a convex shape as seen in the direction along the longitudinal axis L. This results in a particularly favorable elastic deformation behavior. However, this advantageous embodiment is not absolutely essential. For special applications, the leaf spring elements can also be folded outwardly or inwardly in a V-shape, or the peripheral surface of a leaf spring element has a concave curvature in the direction parallel to the longitudinal axis of the applicator.

Der maximale Radius R des Applikators im Bereich seiner Blattfederelemente, der meist auf halbem Wege zwischen dem Stielabschnitt und der Spitze liegt, beträgt vorzugsweise bis maximal 15 mm, besser nur bis maximal 10 mm, vgl. Fig. 4.The maximum radius R of the applicator in the area of its leaf spring elements, which is usually halfway between the handle section and the tip, is preferably up to a maximum of 15 mm, better only to a maximum of 10 mm, cf. Fig. 4 .

Wie man recht gut anhand der Figur 4 sieht, sind die Scheitelpunkte 6 der Blattfederelemente 4 in der Mitte des Applikators, dort, wo dieser die größte radiale Erstreckung aufweist, auf einem gedachten Kreis angeordnet, dessen Radius Ri im Wesentlichen oder besser mindestens der radialen Erstreckung eines Blattfederelements 4 (gerechnet ohne die Finger) entspricht. Idealerweise liegen alle Scheitelpunkte auf dem gleichen gedachten Kreis.How to use the Figure 4 sees, the vertices 6 of the leaf spring elements 4 are in the center of the applicator, where it has the greatest radial extent has, arranged on an imaginary circle, the radius Ri of which corresponds essentially or better at least to the radial extent of a leaf spring element 4 (calculated without the fingers). Ideally, all vertices lie on the same imaginary circle.

Von den Maßen her hat es sich als besonders günstig erwiesen, wenn das jeweilige Blattfederelement eine Länge zwischen 15 mm und 60 mm aufweist. Die Breite der Blattfederelemente in Umfangsrichtung beträgt vorzugsweise 3 mm bis 6 mm. Die größte Erstreckung in radialer Richtung beträgt vorzugsweise maximal 5 mm. Idealerweise ist die Erstreckung der Blattfederelemente in Richtung der Längsachse L um mindestens das Achtfache, besser noch um mindestens das Zehnfache größer als die Erstreckung der Blattfederelemente in radialer Richtung, senkrecht zur Längsachse L.In terms of dimensions, it has proven to be particularly favorable if the respective leaf spring element has a length between 15 mm and 60 mm. The width of the leaf spring elements in the circumferential direction is preferably 3 mm to 6 mm. The greatest extent in the radial direction is preferably a maximum of 5 mm. Ideally, the extension of the leaf spring elements in the direction of the longitudinal axis L is at least eight times, better still at least ten times greater than the extension of the leaf spring elements in the radial direction, perpendicular to the longitudinal axis L.

Der FingerbesatzThe fingerboard

Vorzugsweise sind alle Blattfederelemente 4 oder zumindest die überwiegende Zahl der Blattfederelemente 4 mit Fingern 7 ausgestattet.All leaf spring elements 4 or at least the majority of leaf spring elements 4 are preferably equipped with fingers 7.

Vorzugsweise erstrecken sich die Längsachsen l der Finger überwiegend oder alle in radialer Richtung. Letzteres bedeutet dann, dass sie die Längsachse L des Applikators schneiden. Die Finger stehen dann, insgesamt gesehen und abgesehen von einer eventuellen, genau mittig auf dem Blattfederelement angeordneten Reihe, V-förmig von dem jeweiligen Blattfederelement ab. Auf diese Art und Weise wird ein besonders harmonisches Auftragsverhalten erreicht, auch bei Drehung des Applikators.The longitudinal axes 1 of the fingers preferably extend predominantly or all in the radial direction. The latter then means that they intersect the longitudinal axis L of the applicator. The fingers then, viewed as a whole and apart from a possible row arranged exactly in the center of the leaf spring element, protrude in a V-shape from the respective leaf spring element. In this way, a particularly harmonious application behavior is achieved, even when the applicator is rotated.

Jedes Blattfederelement 4 besitzt zumindest eine Reihe von Fingern 7, die im Regelfall in Richtung parallel zur Längsachse L fluchtend hintereinander aufgestellt sind. Vorzugsweise ist das bzw. jedes fingerbesetzte Blattfederelement mit mehreren solcher Reihen von Fingern 7 ausgestattet. Im Hinblick auf die Flexibilität der Blattfederelemente ist es besonders günstig, wenn die Finger der Reihen, mit denen ein Blattfederelement 4 ausgestattet ist, nicht in Umfangsrichtung alle auf einer Linie liegen. Stattdessen hat es sich als ideal erwiesen, wenn ein Finger einer mittleren Reihe (das muss nicht die einzige mittlere Reihe sein) in Umfangsrichtung gesehen mittig auf der Höhe des Zwischenraums angeordnet ist, der zwischen zwei unmittelbar aufeinanderfolgenden Fingern einer linksseitig und einer rechtsseitig unmittelbar benachbarten Reihe frei ist. Eine solche Aufstellung der Finger führt nämlich dazu, dass auch bei bestimmungsgemäßer Verformung des Blattfederelements 4 noch ein sehr gleichmäßiges Fingerbild erhalten bleibt.Each leaf spring element 4 has at least one row of fingers 7, which as a rule parallel to the direction Longitudinal axis L are set up in alignment one behind the other. The leaf spring element or each finger-studded leaf spring element is preferably equipped with a plurality of such rows of fingers 7. With regard to the flexibility of the leaf spring elements, it is particularly advantageous if the fingers of the rows with which a leaf spring element 4 is equipped do not all lie on one line in the circumferential direction. Instead, it has proven to be ideal if a finger in a middle row (this does not have to be the only middle row) is arranged in the circumferential direction in the middle at the level of the space between two immediately consecutive fingers of a row on the left and a row immediately adjacent on the right free is. Such a positioning of the fingers leads to the fact that even when the leaf spring element 4 is deformed as intended, a very uniform fingerprint is maintained.

Besonders bevorzugt ist es, jedes Blattfederelement mit zwei bis vier und optimalerweise mit genau drei nebeneinander aufgestellten, in Richtung parallel zur Längsachse L verlaufenden Borstenreihen auszustatten. Die Verwendung von drei oder vier Borstenreihen ist insbesondere dann bevorzugt, wenn die Anzahl der Blattfederelemente auf drei Blattfederelemente begrenzt ist.It is particularly preferred to equip each leaf spring element with two to four and optimally with exactly three rows of bristles that are placed side by side and run in the direction parallel to the longitudinal axis L. The use of three or four rows of bristles is particularly preferred when the number of leaf spring elements is limited to three leaf spring elements.

Die Länge der Finger kann konstant sein. Wie man darüber hinaus zusätzlich anhand beispielsweise der Figur 3 sieht, ist es aber in vielen Fällen vorteilhaft, wenn die Länge der Finger im Bereich der Mitte des Borstenbesatzes (entlang der Längsachse L gesehen) ihr Maximum erreicht und zumindest zu einem Ende, vorzugsweise zu beiden Enden hin (distal und proximal) abnimmt.The length of the fingers can be constant. How you can also use, for example, the Figure 3 sees, it is advantageous in many cases if the length of the fingers in the area of the center of the bristle facing (viewed along the longitudinal axis L) reaches its maximum and decreases at least towards one end, preferably towards both ends (distal and proximal).

Der Begriff des Fingers umfasst sowohl die Ausgestaltung als Borste als auch die Ausgestaltung als Kammzinken. Spezielle und für bestimmte Anwendungsfälle besonders bevorzugte Ausgestaltungsformen verwenden Borsten oder Kammzinken in Gestalt von Lamellen 7b oder Kreisscheibensegmenten 7a. Eine Lamelle 7b ist dabei ein vorzugsweise rechteckiges Gebilde, im Idealfall mit in radialer Richtung parallelen Seitenkanten, dessen Erstreckung in Umfangsrichtung mindestens dreimal, besser mindestens fünfmal größer ist als seine Erstreckung in Richtung parallel zur Applikatorlängsachse.The term “finger” encompasses both the design as a bristle and the design as a comb teeth. Specific and for certain applications particularly preferred embodiments use bristles or comb teeth in the form of lamellae 7b or circular disk segments 7a. A lamella 7b is a preferably rectangular structure, ideally with side edges parallel in the radial direction, the extent of which in the circumferential direction is at least three times, better at least five times greater than its extent in the direction parallel to the longitudinal axis of the applicator.

Sofern Kreisscheibensegmente 7a vorgesehen sind, haben diese in radialer Richtung vom Fuß hin bis zu ihrem Außenumfang einen Öffnungswinkel Wö von bevorzugt 15° bis 35°. Insoweit sei auf die Figur 13 verwiesen, wo dies dargestellt ist.If circular disk segments 7a are provided, they have an opening angle Wö of preferably 15 ° to 35 ° in the radial direction from the foot to their outer circumference. In that regard, be on the Figure 13 referenced where this is shown.

Zu Figur 13 sei angemerkt, dass der gestrichelte Kreis nicht etwa einen Applikatorkern darstellt, sondern lediglich symbolisiert, dass in Umfangsrichtung vorzugsweise mehrere Blattfederelemente vorgesehen sind, die einen derartigen Besatz tragen. Für manche Anwendungsfälle ist es auch besonders günstig, wenn solche Lamellen und/oder Kreissegmente und klassische Borsten mit kreisrundem Querschnitt und Kegelform gemischt positioniert sind.To Figure 13 it should be noted that the dashed circle does not represent an applicator core, but merely symbolizes that a plurality of leaf spring elements are preferably provided in the circumferential direction which carry such a trim. For some applications it is also particularly favorable if such lamellae and / or circular segments and classic bristles with a circular cross section and conical shape are positioned in a mixed manner.

Explizit darauf hinzuweisen ist noch, dass es für manche Ausführungsformen besonders günstig ist, wenn sich die Kreisscheibensegmente 7a in radialer Richtung nach außen so weit verbreitern, dass sie in Umfangsrichtung auf einer oder besser beiden Seiten über das sie tragende Blattfederelement 4 hinausstehen, in radialer Projektion gesehen, vgl. Figur 13.It should also be explicitly pointed out that it is particularly favorable for some embodiments if the circular disk segments 7a widen outward in the radial direction so far that they protrude in the circumferential direction on one or better both sides of the leaf spring element 4 carrying them, in radial projection seen, cf. Figure 13 .

Ebenfalls explizit darauf hinzuweisen ist, dass die Lamellen in Umfangsrichtung vorzugsweise ebenso breit (± 15°) sind wie die sie tragenden Blattfederelemente, vgl. ebenfalls Figur 13. Vorzugsweise ist die überwiegende Zahl der Blattfederelemente 4 mit Fingern in Gestalt von Borsten versehen, idealerweise solchen, die einen kreisförmigen oder elliptischen Querschnitt aufweisen. Als Borste wird dabei ein Gebilde bezeichnet, das vorzugsweise derart aussieht, wie das die Figur 12 veranschaulicht. Eine Borste in diesem Sinne ist einstückig und einstofflich mit einer Kunststoffschicht am Blattfederelement 4 oder mit dem gesamten Blattfederelement 4 verbunden. Eine solche Borste ist im Regelfall durch Spritzguss entstanden. Dabei ist der Spritzguss hier nicht nur ein Verfahren, sondern gleichzeitig eine mittelbare Angabe für die Beschaffenheit der Borste. Denn durch das Spritzgießen erfolgt eine starke Ausrichtung der Kunststoffmolekülketten einer Borste, die Kunststoffmolekülketten werden sozusagen in die Länge gezogen, in Richtung entlang der Längsachse l eines Fingers. Auf diese Art und Weise werden den Borsten ein besonders gutes Wiederaufrichtvermögen und eine hohe Flexibilität verliehen.It should also be pointed out explicitly that the lamellae are preferably just as wide (± 15 °) in the circumferential direction as the leaf spring elements supporting them, see also Figure 13 . The majority of the leaf spring elements 4 are preferably provided with fingers in the form of bristles, ideally those that have a circular or elliptical cross-section. A structure is referred to as a bristle that preferably looks like the one Figure 12 illustrated. A bristle in this sense is integrally and integrally connected with a plastic layer on the leaf spring element 4 or with the entire leaf spring element 4. Such a bristle is usually made by injection molding. Injection molding is not just a process here, but also an indirect indication of the nature of the bristle. This is because the injection molding results in a strong alignment of the plastic molecule chains of a bristle, the plastic molecule chains are stretched, so to speak, in the direction along the longitudinal axis 1 of a finger. In this way, the bristles are given a particularly good erecting capacity and a high degree of flexibility.

Idealerweise besitzt eine Borste das Aussehen eines Kegels, sie verjüngt sich vom Borstenfuß hin zur Borstenspitze. Typischerweise beträgt der Durchmesser DF einer einzelnen Borste im Bereich des Borstenfußes, oberhalb der Verrundung, mit der die Borste in das Blattfederelement übergehen mag, zwischen 0,08 mm und 0,35 mm. Die Länge LB solcher Borsten des Besatzes in Richtung parallel zu ihrer Längsachse l beträgt vorzugsweise zumindest überwiegend oder vollständig zwischen 2,5 mm und 10 mm. Eine solche Borste ist im Regelfall derart elastisch, dass ihr freies Ende unter den bei der Applikation auftretenden Kräften reversibel elastisch um einen Betrag AL senkrecht zur borstenseitigen Längsachse l ausgelenkt werden kann, der mindestens dem Vierfachen des Borstenfußdurchmessers, idealerweise mindestens dem Sechsfachen des Borstenfußdurchmessers entspricht. Eine Ausnahme hiervon mag bei Borsten gelten, deren Länge in Richtung der Längsachse l weniger als 4 mm beträgt.A bristle ideally has the appearance of a cone, it tapers from the bristle base to the bristle tip. The diameter DF of an individual bristle in the area of the bristle base, above the rounding with which the bristle may merge into the leaf spring element, is between 0.08 mm and 0.35 mm. The length LB of such bristles of the facing in the direction parallel to their longitudinal axis 1 is preferably at least predominantly or completely between 2.5 mm and 10 mm. Such a bristle is usually so elastic that its free end can be reversibly elastically deflected under the forces occurring during application by an amount AL perpendicular to the bristle-side longitudinal axis l, which corresponds to at least four times the bristle foot diameter, ideally at least six times the bristle foot diameter. An exception to this may apply to bristles whose length in the direction of the longitudinal axis 1 is less than 4 mm.

Der Kegelmantelwinkel α beträgt vorzugsweise zwischen 0,5° und 5°, vgl. Fig. 12.The cone surface angle α is preferably between 0.5 ° and 5 °, cf. Fig. 12 .

ZWEITES AUSFÜHRUNGSBEISPIELSECOND EXAMPLE

Die Figuren 7 bis 11 zeigen ein zweites Ausführungsbeispiel des erfindungsgemäßen Applikators. Das für das erste Ausführungsbeispiel Gesagte gilt hier sinngemäß, sofern sich aus dem nachfolgend Gesagten nichts anderes ergibt. Wichtig ist, dass auch dieser Applikator keine sich entlang der zentralen Längsachse des Applikators erstreckende Stange und keinen sich entlang der zentralen Längsachse des Applikators erstreckenden Kern besitzt, der das proximale Endteil 3 und das distale Endteil 2 miteinander verbindet. Auch hier ist der Applikator entlang der Blattfederelemente im Kern materialfrei.The Figures 7 to 11 show a second embodiment of the applicator according to the invention. What has been said for the first exemplary embodiment applies analogously here, unless otherwise stated in what follows. It is important that this applicator also has no rod extending along the central longitudinal axis of the applicator and no core extending along the central longitudinal axis of the applicator, which connects the proximal end part 3 and the distal end part 2 to one another. Here too, the core of the applicator is free of material along the leaf spring elements.

Auch wenn das anhand der Figuren 7 bis 11 nicht sehr deutlich zu erkennen ist, ist es auch hier bevorzugt so, dass die sich in radialer Richtung erstreckenden, einander zugewandten Flanken zweier unmittelbar benachbarter Blattfederelemente nicht parallel zueinander verlaufen. Stattdessen verlaufen sie so, dass der zwischen ihnen befindliche Abstand in radial einwärtiger Richtung hin zur Längsachse L kleiner wird.Even if that's based on the Figures 7 to 11 cannot be seen very clearly, it is also preferred here that the flanks of two immediately adjacent leaf spring elements extending in the radial direction and facing one another do not run parallel to one another. Instead, they run in such a way that the distance between them in the radially inward direction towards the longitudinal axis L becomes smaller.

Die Besonderheit ist hier die, dass nicht nur drei in Umfangsrichtung gesehen nebeneinander positionierte Blattfederelemente vorgesehen sind, sondern sechs in Umfangsrichtung gesehen nebeneinander positionierte Blattfederelemente. Die einzelnen Blattfederelemente sind so gestaltet, wie das oben bereits beschrieben worden ist. Allerdings trägt jedes Blattfederelement an seiner Außenoberfläche hier nur zwei Reihen aus in Richtung parallel entlang der Längsachse hintereinander aufgestellten Borsten.The special feature here is that not only three leaf spring elements positioned next to one another as seen in the circumferential direction are provided, but rather six leaf spring elements positioned next to one another as seen in the circumferential direction. The individual leaf spring elements are designed as has already been described above. However, each leaf spring element here only has two rows of bristles arranged one behind the other in the direction parallel along the longitudinal axis on its outer surface.

Die beiden Fingerreihen verlaufen hier vollständig parallel zueinander, d. h. die einzelnen Borsten der überwiegenden Anzahl der bzw. aller Blattfederelemente bilden hier in Umfangsrichtung gesehen jeweils Borstenkränze.The two rows of fingers here run completely parallel to one another, ie the individual bristles of the predominant number of or all of the leaf spring elements here each form bristle rings as seen in the circumferential direction.
