Description

Die Erfindung betrifft einen Pinsel zum Auftragen einer flüchtige Lösungsmittel enthaltenden Flüssigkeit, insbe­sondere Nagellack, mit einem Schaft, in dessen einem Ende ein Borstenkörper aufgenommen ist, und dessen anderes En­de in einen Stutzen mit größeren Querabmessungen als der Schaft ausläuft, sowie mit einer Einrichtung zum abdich­tenden Verschluß einer den Pinsel aufnehmenden, einen Halsteil aufweisenden Flasche oder dergl. Behälter.The invention relates to a brush for applying a volatile solvent-containing liquid, in particular nail polish, with a shaft, in one end of which a bristle body is accommodated, and the other end of which runs out into a socket with larger transverse dimensions than the shaft, and with a device for sealing Closure of a bottle or the like container holding the brush and having a neck part.

Derartige Pinsel sind in den unterschiedlichsten Ausfüh­rungen aus der Praxis bekannt. Üblicherweise sind diese Pinsel in eine die Flasche verschließende Schraubkappe eingesetzt, die entsprechend den ästhetischen Vorstel­lungen der Nagellackhersteller geformt ist.Such brushes are known in a wide variety of designs from practice. These brushes are usually inserted into a screw cap that closes the bottle and is shaped according to the aesthetic ideas of the nail polish manufacturers.

Nagellack enthält einen relativ hohen Anteil an flüchti­gen Lösungsmitteln, beispielsweise Aceton. Die Schraub­verschlüsse stellen jedoch lediglich in vollständig zuge­schraubtem Zustand einen luftdichten Verschluß her. Da nach dem Auftragen des Nagellackes der Pinsel mit der Schraubkappe zwar in die Flasche zurückgesteckt wird, da­bei jedoch oftmals der Schraubverschluß nicht völlig zu­gedreht wird, kann das Lösungsmittel aus der Flasche ver­dunsten und der Nagellack trocknet zumindest an seiner Oberfläche ein.Nail polish contains a relatively high proportion of volatile solvents, e.g. acetone. However, the screw caps only produce an airtight seal when fully screwed on. Since after applying the nail polish the brush with the Although the screw cap is put back into the bottle, but often the screw cap is not completely closed, the solvent can evaporate from the bottle and the nail polish dries at least on its surface.

Aufgabe der Erfindung ist es daher, einen Pinsel mit Fla­schenverschlußeinrichtung zu schaffen, die dem Eintrock­nen des Flascheninhaltes entgegenwirkt, auch wenn die Flasche nicht ordnungsgemäß verschlossen ist.The object of the invention is therefore to provide a brush with a bottle closure device which counteracts the drying of the bottle contents, even if the bottle is not properly closed.

Diese Aufgabe wird durch einen an dem Stutzen umlaufenden Ringwulst, der bei in den Flaschenhalsteil der Flasche oder dergl. Behälter vollständig oder wenigstens fast vollständig eingeführtem Pinsel für eine abdichtende An­lage an der Innenwand des Halsteiles längs einer an sei­nem Umfang ringsumlaufenden Dichtfläche eingerichtet ist.This object is achieved by an annular bead running around the neck, which, when the brush is fully or at least almost completely inserted into the bottle neck part of the bottle or the like, is arranged for a sealing contact on the inner wall of the neck part along a circumferential sealing surface.

Üblicherweise ist der Pinsel als Ganzes - ohne den Bor­stenkörper aus Nylon - also der Schaft, der Stutzen und der Ringwulst aus verformbarem und lösungsmittelbestän­digem Material, vorzugsweise einem thermoplastischen Kunststoff, z.B. Polyethylen, als einstückiges Spritzguß­teil hergestellt. Dabei haben der Schaft und der Stutzen in der Regel eine rotationssymmetrische Gestalt, was so­wohl die Herstellung als auch den Gebrauch vereinfacht, da der Schaft und ein Teil des Stutzens in die meist run­de Öffnung des Halsteiles der Nagellackflasche einführbar sein müssen. Wenn zumindest der Borstenkörper im Quer­schnitt oval ist, steht für die Applikation der Flüssig­keit, z.B. des Nagellacks, eine größere Fläche zur Ver­fügung.Usually the brush as a whole - without the bristle body made of nylon - i.e. the shaft, the socket and the ring bulge are made of deformable and solvent-resistant material, preferably a thermoplastic, e.g. Polyethylene, manufactured as a one-piece injection molded part. The shaft and the socket generally have a rotationally symmetrical shape, which simplifies both production and use, since the shaft and part of the socket must be insertable into the usually round opening of the neck part of the nail polish bottle. If at least the bristle body is oval in cross section, the application of the liquid, e.g. of the nail polish, a larger area is available.

Bei einer bevorzugten Ausführungsform weist der Ringwulst eine im wesentlichen kreisabschnittsförmige Querschnitts­ gestalt auf. Damit ist eine Abdichtung der Flasche bei in den Halsteil eingeführtem Pinsel gewährleistet, da der Ringwulst beim Einführen des Pinsels an der Innenwand des Halsteiles eine umlaufende dichtende Anlagefläche her­stellt, die eine sichere Abdichtung der Flasche gewähr­leistet, auch wenn die Flasche nicht vollständig ver­schlossen ist.In a preferred embodiment, the annular bead has an essentially circular cross-section shape up. This ensures that the bottle is sealed when the brush is inserted into the neck part, since when the brush is inserted on the inner wall of the neck part, the annular bead creates a circumferential, sealing contact surface which ensures a secure seal of the bottle, even if the bottle is not completely closed.

Um den Pinsel mit der daran befindlichen Schraubkappe bei der Herstellung und im späteren Gebrauch leichter und si­cherer in den Halsteil der Flasche einführen bzw. ver­schrauben zu können, kann der Stutzen in einen sich an den Ringwulst in Richtung auf den Schaft anschließenden Übergangsbereich auslaufend ausgebildet sein, der sich auf den Schaft hin verjüngt. Ein derartiger beispielswei­se konischer Übergangsbereich zentriert den Pinsel bezüg­lich des Halsteiles derart, daß der Ringwulst längs sei­nes Umfanges gleichmäßig an der Innenwand des Halsteiles in Anlage kommt.In order to be able to insert or screw the brush with the screw cap attached to it more easily and safely into the neck portion of the bottle during manufacture and later use, the nozzle can be formed in a transition region adjoining the annular bead in the direction of the shaft, that tapers towards the shaft. Such a, for example, conical transition area centers the brush with respect to the neck part in such a way that the annular bead comes into contact uniformly along its circumference on the inner wall of the neck part.

Bei einer bevorzugten Ausführungsform ist an dem Stutzen zwischen dem Ringwulst und der Stirnfläche des Stutzens eine umlaufende Ringschulter angeformt, der bei in den Halsteil der Flasche vollständig oder wenigstens fast vollständig eingeführtem Pinsel oben auf dem Rand des Halsteiles aufsitzen kann. Diese Maßnahme bewirkt insbe­sondere im zugeschraubten Zustand der Schraubkappe eine zusätzliche Abdichtung der Flasche etc., außerdem hat da­mit das Gewinde in der Schraubkappe einen eindeutigen An­schlag und kann nicht überdreht werden. Durch die Rast­mittel ist der Pinsel sicher mit der Schraubkappe ver­rastet und kann auch dann, wenn er durch angetrockneten Nagellack festsitzt, ohne großen Kraftaufwand gelöst wer­den.In a preferred embodiment, a circumferential annular shoulder is formed on the neck between the annular bead and the end face of the neck, which can rest on the top of the neck part when the brush is completely or at least almost completely inserted into the neck part of the bottle. This measure brings about an additional sealing of the bottle etc., in particular when the screw cap is screwed on. In addition, the thread in the screw cap has a clear stop and cannot be overtightened. Thanks to the locking means, the brush is securely locked in place with the screw cap and, even if it is stuck due to dried nail polish, can be loosened with little effort.

Mit Vorteil weist in diesem Fall der Pinsel an der dem Rand des Halsteiles der Flasche zugewandten Stirnfläche der Ringschulter in radialem Abstand zu der Außenwand des Stutzens koaxial zu diesem eine umlaufende Dichtlippe auf. Damit sind Unebenheiten am Rand des Halsteiles leichter auszugleichen, da die Dichtlippe sich besser an kleine Vertiefungen oder Erhebungen des üblicherweise ungeschliffenen Randes des Halsteiles anpaßt.In this case, the brush advantageously has a circumferential sealing lip on the end face of the annular shoulder facing the edge of the neck part of the bottle at a radial distance from the outer wall of the neck, coaxially with the neck. This makes it easier to compensate for unevenness on the edge of the neck part, since the sealing lip adapts better to small depressions or elevations of the edge of the neck part, which is usually uncut.

Bei einer anderen möglichen Ausführungsform der Dicht­lippe hat diese eine im wesentlichen dreieckförmige Querschnittsgestalt, wobei die von der Stirnfläche der Ringschulter wegweisende Umlaufkante der Dichtlippe bei in den Halsteil der Flasche vollständig oder wenigstens fast vollständig eingeführtem Pinsel oben auf dem Rand des Halsteiles dicht aufsitzen kann. Es sind aber auch andere Querschnittsgestaltungen, beispielsweise halbrunde oder rechteckige denkbar.In another possible embodiment of the sealing lip, it has an essentially triangular cross-sectional shape, the circumferential edge of the sealing lip pointing away from the end face of the annular shoulder being able to sit tightly on the top of the edge of the neck part when the brush is completely or at least almost completely inserted into the neck part of the bottle. However, other cross-sectional configurations, for example semicircular or rectangular, are also conceivable.

Mit Vorteil ist die Dichtlippe einstückig an der Stirn­fläche der Ringschulter angeformt und aus dem gleichen Material gebildet wie die Ringschulter.The sealing lip is advantageously formed in one piece on the end face of the ring shoulder and formed from the same material as the ring shoulder.

In the drawing, an embodiment of the object of the invention is illustrated. Show it:
  • 1 is a brush according to the invention in a partially sectioned side view,
  • FIG. 2 shows a section from FIG. 1, designated II, in an enlarged sectional view, FIG.
  • Fig. 3 shows a screw cap for receiving the brushes of FIG. 1 in a partially sectioned side view
  • Fig. 4 shows the shaft of the brush of Fig. 1, taken along the line IV-IV of Fig. 1, in an enlarged view.

In Fig. 1 ist ein Pinsel 1 zum Auftragen von Nagellack veranschaulicht. Der Pinsel 1 ist als Spritzgußteil aus Polyethylen an einem Stück hergestellt und besteht aus einem länglichen Schaft 2, in dessen unterem Ende stirn­seitig ein Borstenkörper 3 mit Nylonborsten aufgenommen ist, und dessen oberes Ende in einen rotationssymmetri­schen Stutzen 4 größeren Durchmessers als der Schaft 2 ausläuft.In Fig. 1, a brush 1 for applying nail polish is illustrated. The brush 1 is made as an injection-molded part from polyethylene in one piece and consists of an elongated shaft 2, in the lower end of which a bristle body 3 with nylon bristles is accommodated on the end face, and the upper end of which ends in a rotationally symmetrical nozzle 4 of larger diameter than the shaft 2.

Der aus Materialersparnisgründen innen hohle Stutzen 4 hat eine im wesentlichen kreiszylindrische Gestalt und weist über einen Teil seiner Länge einen Außendurchmesser auf, der geringfügig kleiner als der Innendurchmessers eines lediglich teilweise veranschaulichten Halsteiles 6 einer Flasche oder eines ähnlichen Behälters ist, in den der Pinsel 1 einführbar ist. Im unteren Drittel des Stut­zens 4 ist an diesem einstückig ein umlaufender im Quer­schnitt kreisabschnittförmiger Ringwulst 7 angeformt, dessen Außendurchmesser etwas größer als der Innendurch­messer des Halsteiles 6 ist. Bei in den Halsteil 6 der Flasche vollständig oder wenigstens fast vollständig ein­geführtem Stutzen 4 liegt der Ringwulst 7 an der Innen­wand 8 des Halsteiles 6 unter radialer Vorspannung dicht an und bildet längs seines Umfanges mit der Innenwand 8 einen ringsumlaufenden Anlagebereich in Gestalt einer Dichtfläche 10.The inside hollow socket 4 for reasons of material savings has an essentially circular cylindrical shape and has over part of its length an outer diameter which is slightly smaller than the inner diameter of a neck part 6 of a bottle or a similar container which is only partially illustrated and into which the brush 1 can be inserted is. In the lower third of the connecting piece 4, a circumferential annular bead 7 with a circular cross-section is integrally formed on the connecting piece 4, the outer diameter of which is somewhat larger than the inner diameter of the neck part 6. When the neck 4 is completely or at least almost completely inserted into the neck part 6 of the bottle, the annular bead 7 lies tightly against the inner wall 8 of the neck part 6 under radial prestress and forms a circumferential contact area in the form of a sealing surface 10 with the inner wall 8 along its circumference.

Anschließend an den Ringwulst 7 läuft der Stutzen 4 zu dem Schaft 2 hin in einen Übergangsbereich 9 aus, der sich in Richtung auf den Schaft 2 hin konisch verjüngt.Subsequent to the annular bead 7, the connecting piece 4 runs towards the shaft 2 into a transition region 9 which tapers conically in the direction of the shaft 2.

Es ist auch möglich, in dem Stutzen 4 eine umlaufende Ringnut vorzusehen, in die ein Dichtungsring so einge­setzt ist, daß er an der Innenwand 8 des Halsteiles 6 so wie der oben beschriebene Ringwulst 7 unter radialer Vor­spannung dicht anliegt.It is also possible to provide a circumferential annular groove in the socket 4, in which a sealing ring is inserted so that it is on the inner wall 8 of the neck part 6 how the annular bead 7 described above lies tightly under radial prestress.

Zwischen dem Ringwulst 7 und der Stirnfläche 11 des Stut­zens 4 ist eine umlaufende etwa kreiszylindrisch gestal­tete Ringschulter 12 angeformt, die bei in den Halsteil 6 der Flasche vollständig oder wenigstens fast vollständig eingeführtem Pinsel 1 oben auf dem Rand 13 des Halsteiles aufsitzen kann. An der oberen Außenkante der Ringschulter 12 ist eine Fase 14, sowie an der Stirnfläche 11 eine Fase 15 ausgebildet, um ein Einsetzen in eine weiter un­tenstehend beschriebene Schraubkappe 16 zu erleichtern.Between the ring bead 7 and the end face 11 of the socket 4, a circumferential, approximately cylindrical cylindrical ring shoulder 12 is formed, which can rest on the rim 13 of the neck part when the brush 1 is completely or at least almost completely inserted into the neck part 6 of the bottle. A chamfer 14 is formed on the upper outer edge of the annular shoulder 12, and a chamfer 15 is formed on the end face 11 in order to facilitate insertion into a screw cap 16 described below.

An der dem Rand 13 des Halsteiles 6 zugewandten Stirn­fläche 17 der Ringschulter 12 ist in radialem Abstand zur Außenwand 18 des Stutzens koaxial zu diesem eine um­laufende Dichtlippe 19 einstückig angeformt, die aus dem gleichen Material besteht wie die Ringschulter 12.A circumferential sealing lip 19, which is made of the same material as the annular shoulder 12, is integrally formed on the end face 17 of the annular shoulder 12 facing the edge 13 of the neck part 6 at a radial distance from the outer wall 18 of the connecting piece.

Die Dichtlippe 19 hat eine im wesentlichen dreieckförmige Querschnittsgestalt, wobei die von der Stirnfläche 17 der Ringschulter 12 wegweisende Umlaufkante 21 der Dichtlippe 19 bei in den Halsteil vollständig oder wenigstens fast vollständig eingeführtem Pinsel 1 etwa mittig oben auf dem Rand 13 des Halsteiles 6 dicht aufsitzen kann.The sealing lip 19 has an essentially triangular cross-sectional shape, the peripheral edge 21 of the sealing lip 19 pointing away from the end face 17 of the annular shoulder 12 being able to sit tightly on the edge 13 of the neck part 6 approximately in the middle at the top 13 when the brush 1 is completely or at least almost completely inserted into the neck part .

Der Halsteil 6 trägt an seiner Außenseite ein in den Fig. 1 und 2 lediglich andeutungsweise veranschaulichtes Außengewinde 22. Eine in Fig. 3 dargestellte Schraubkappe 16, die aus Kunststoff, beispielsweise Polypropylen, ebenfalls als Spritzgußteil hergestellt ist und in die ein Innengewinde 23 eingeformt ist, kann auf das Außenge­winde 22 aufgeschraubt werden. An das Innengewinde 23 an­schließend ist im Innern der Schraubkappe 16 eine zylin­drisch gestufte Ausnehmung 24 vorhanden, deren Gestalt der des Stutzens 4 mit der Ringschulter 12 entspricht. In diese Ausnehmung 24 wird der Stutzen 4 eingesetzt, wobei die Fasen 14 und 15 an der Stirnfläche 11 bzw. an der Ringschulter 12 das Einsetzen erleichtern.The neck part 6 has on its outside an external thread 22, which is only hinted at in FIGS. 1 and 2. A screw cap 16 shown in FIG. 3, which is also made of plastic, for example polypropylene, as an injection molded part and into which an internal thread 23 is formed , can be screwed onto the external thread 22. Following the internal thread 23 there is a cylindrically stepped recess 24 in the interior of the screw cap 16, the shape of which corresponds to that of the socket 4 with the annular shoulder 12. In this recess 24, the nozzle 4 is used, the chamfers 14 and 15 on the end face 11 and on the annular shoulder 12 facilitate the insertion.

An dem Stutzen 4 ist zwischen seiner Stirnfläche 11 und der Ringschulter 12 eine sich über den ganzen Umfang er­streckende Rastnut 25 vorgesehen, die parallel zu der Ringschulter 12 verläuft. Der Rastnut 25 entsprechend ist in der Ausnehmung 24 der Schraubkappe 16 eine um­laufende Rastwulst 26 ausgebildet. Bei in die Schraub­kappe 16 eingesetztem Pinsel 1 verrasten die von der Rastnut 25 und der Rastwulst 26 gebildeten Rastmittel miteinander und der Pinsel 1 ist unverlierbar in der Schraubkappe 16 gehalten.On the nozzle 4 between its end face 11 and the annular shoulder 12, a locking groove 25 is provided which extends over the entire circumference and runs parallel to the annular shoulder 12. Corresponding to the locking groove 25, a circumferential locking bead 26 is formed in the recess 24 of the screw cap 16. When the brush 1 is inserted into the screw cap 16, the latching means formed by the latching groove 25 and the latching bead 26 latch together and the brush 1 is held captively in the screw cap 16.

Der Schaft 2 und der Borstenkörper 3 können im Quer­schnitt eine kreisförmige oder eine länglich-ovale Ge­stalt aufweisen. Bei der in Fig. 1 gezeigten kreis­förmigen Gestalt ist der Borstenkörper 3 mit seinem zu dem Schaft 2 zeigenden Ende 27 in einer zentrischen Bohrung 28 in dem Schaft 2 aufgenommen und geeignet verklebt. In Fig. 4 ist gezeigt, daß bei ovalem Schaft 2 in seiner von dem Stutzen 4 abgelegenen Bodenfläche 29 eine annähernd ovale, schlitzförmige Vertiefung 31 vorgesehen ist, in die der Borstenkörper 3 mit seinem Ende 27 eingeklebt ist.The shaft 2 and the bristle body 3 can have a circular or an elongated oval shape in cross section. In the circular shape shown in FIG. 1, the bristle body 3 is received with its end 27 pointing towards the shaft 2 in a central bore 28 in the shaft 2 and is suitably glued. 4 shows that in the case of an oval shaft 2, an approximately oval, slot-shaped depression 31 is provided in its bottom surface 29 remote from the socket 4, into which the bristle body 3 is glued with its end 27.
