Description

Die Erfindung betrifft ein Auftraggerät für ein flüssiges, pastöses, gelartiges, wachsartiges oder pulverförmiges Produkt nach dem Oberbegriff von Anspruch 1, der aus der DE 101 21 381 C bekannt ist.The invention relates to an applicator for a liquid, pasty, gel-like, waxy or powdery product according to the preamble of claim 1, which is known from DE 101 21 381 C is known.

Ein vergleichbares Auftraggerät ist aus der EP 1 273 245 A1 bekannt. Dabei werden das erste Stellelement von einer Patrone und das zweite Stellelement von einem Schaft gebildet. In einem ersten Betriebszustand (Anfangszustand vor erstem Gebrauch) ist die Patrone nicht vollständig mit dem Produkt gefüllt. Vielmehr ist ein Totraum vorhanden. Zur Überwindung des Totraums dient die erste Fördereinrichtung, wohingegen die zweite Fördereinrichtung der Feindosierung dient. Das erste Förderelement ist mit dem zweiten Förderelement identisch. Es handelt sich um einen in der Patrone axial verschieblichen Kolben. Wird der Kolben durch Betätigung der zweiten Fördereinrichtung axial bewegt, so bewegt er sich bezüglich sowohl der Patrone als auch des Schaftes in Axialrichtung, und zwar um gleiche Strecken. Daher werden die Patrone und der Schaft nicht in Axialrichtung gegeneinander bewegt.A comparable applicator is from the EP 1 273 245 A1 known. In this case, the first control element of a cartridge and the second actuator are formed by a shaft. In a first operating state (initial state before first use) the cartridge is not completely filled with the product. Rather, there is a dead space. To overcome the dead space is the first conveyor, whereas the second conveyor is the fine metering. The first conveying element is identical to the second conveying element. It is an axially displaceable in the cartridge piston. If the piston is moved axially by actuation of the second conveyor, it moves with respect to both the cartridge and the shaft in the axial direction, namely to same routes. Therefore, the cartridge and the shaft are not moved in the axial direction against each other.

Anders liegen die Dinge bei Betätigung der ersten Fördereinrichtung zur Überwindung des Totraums. Dabei wird nämlich der Kolben nur bezüglich der Patrone, nicht aber bezüglich des Schaftes axial bewegt, weshalb sich in diesem Fall die Patrone axial bezüglich des Schaftes bewegt. Damit einher geht eine Verkürzung des gesamten Auftraggerätes.Things are different when pressing the first conveyor to overcome the dead space. Namely, the piston is moved axially only with respect to the cartridge, but not with respect to the shaft, which is why in this case the cartridge moves axially with respect to the shaft. This is accompanied by a shortening of the entire application device.

Eine solche Verkürzung ist nicht wünschenswert, weil das Auftraggerät eine bestimmte Mindestlänge braucht, um geeignet handhabbar zu sein.Such shortening is not desirable because the applicator needs a certain minimum length to be handled properly.

Ein weiteres vergleichbares Auftraggerät ist bekannt aus der JP 2002/034652 A .Another comparable applicator is known from the JP 2002/034652 A ,

Der Erfindung liegt die Aufgabe zugrunde, das aus der DE 101 21 381 C bekannte Auftraggerät durch eine geeignete Auswahl des ersten Gewindeelements zu verbessern.The invention is based on the object, from the DE 101 21 381 C known applicator to improve by a suitable selection of the first threaded member.

Erfindungsgemäß wird die gestellte Aufgabe dadurch gelöst, daß sich eine Ringnut an die wendelförmige Nut anschließt.According to the invention this object is achieved in that an annular groove connects to the helical groove.

Bei der erfindungsgemäßen Auftragvorrichtung führt eine Betätigung der ersten Fördereinrichtung zu einer Verschiebung des ersten Förderelements sowohl bezüglich des ersten Stellelements, als auch bezüglich des zweiten Stellelements, so daß die Stellelemente sich nicht gegeneinander axial verschieben. Die Axiallänge des Auftraggerätes bleibt mithin erhalten.In the application device according to the invention an actuation of the first conveyor leads to a displacement of the first conveying element both with respect to the first actuating element, as well as with respect to the second actuating element, so that the adjusting elements do not move axially against each other. The axial length of the applicator is thus retained.

Da die erste Fördereinrichtung bevorzugt dazu dient, einen Totraum zu überwinden, ist es erfindungsgemäß vorgesehen, daß die erste Fördereinrichtung ein Schraubgewinde mit einem ersten und einem zweiten Gewindeelement aufweist, wobei die beiden Gewindeelemente bei gegenseitiger Verstellung über ein vorbestimmtes Maß hinaus außer Eingriff kommen. Das vorbestimmte Maß ist dabei derart gewählt, daß die beiden Gewindeelemente dann außer Eingriff kommen, wenn der Totraum überwunden ist.Since the first conveyor preferably serves to overcome a dead space, it is provided according to the invention that the first conveyor has a screw thread with a first and a second threaded member, the two threaded elements come out with mutual adjustment beyond a predetermined amount. The predetermined dimension is chosen such that the two threaded elements then disengage when the dead space is overcome.

Da das erste Gewindeelement eine wendelförmige Nut ist, an die sich eine Ringnut anschließt, wird das zweite Gewindeelement bei einer Verstellung über das vorbestimmte Maß hinaus aus der wendelförmigen Nut in die Ringnut laufen, so daß ein weiteres Verstellen keine weitere Axialverschiebung der beiden Gewindeelemente gegeneinander bewirkt.Since the first threaded member is a helical groove, followed by an annular groove, the second threaded member will run in an adjustment beyond the predetermined extent out of the helical groove in the annular groove, so that further adjustment causes no further axial displacement of the two threaded elements against each other ,

Die zweite Fördereinrichtung weist erfindungsgemäß bevorzugt (ebenfalls) ein Schraubgewinde auf, und zwar mit einem dritten und einem vierten Gewindeelement.The second conveyor according to the invention preferably (also) has a screw thread, with a third and a fourth threaded element.

Zur weiteren Vereinfachung des erfindungsgemäßen Auftraggerätes ist es bevorzugt, daß das dritte Gewindeelement einstückig mit dem ersten Gewindeelement ausgebildet ist.To further simplify the application device according to the invention, it is preferred that the third threaded element is formed integrally with the first threaded member.

Ferner kann vorgesehen sein, daß das vierte Gewindeelement einstückig mit dem Förderelement ausgebildet ist.Furthermore, it can be provided that the fourth threaded element is formed integrally with the conveying element.

Auch kann erfindungsgemäß vorgesehen sein, daß das zweite Gewindeelement einstückig mit dem ersten Stellelement ausgebildet ist.It can also be provided according to the invention that the second threaded element is formed integrally with the first actuating element.

Es ergibt sich weiterhin eine Vereinfachung des Gesamtaufbaus des erfindungsgemäßen Auftraggerätes, wenn das zweite Gewindeelement über ein Filmscharnier mit dem ersten Stellelement verbunden ist.It also results in a simplification of the overall structure of the applicator device according to the invention, when the second threaded member is connected via a film hinge with the first actuator.

Wie bereits oben erwähnt, kann es sich bei dem ersten Stellelement um eine Patrone handeln, während das zweite Stellelement bevorzugt ein Schaft ist.As already mentioned above, the first control element can be a cartridge, while the second control element is preferably a shaft.

Schließlich ist erfindungsgemäß bevorzugt ein Schoner vorgesehen, der mit dem ersten oder dem zweiten Stellelement drehgekoppelt und mit dem zweiten oder dem ersten Stellelement derart verschraubt ist, daß ein Abschrauben des Schoners zu einer Betätigung der ersten und/oder der zweiten Fördereinrichtung führt.Finally, a schooner according to the invention is preferably provided, which is rotationally coupled to the first or the second actuator and screwed to the second or the first control element such that unscrewing the schooner leads to an actuation of the first and / or the second conveyor.

Auf diese Weise kann erreicht werden, daß bereits das Abschrauben des Schoners zu einer Förderung des Produktes derart führt, daß der Totraum überwunden ist.In this way it can be achieved that even unscrewing the schooner leads to a promotion of the product such that the dead space is overcome.

Im folgenden ist die Erfindung anhand bevorzugter Ausführungsbeispiele unter Bezugnahme auf die beiliegende Zeichnung mit weiteren Einzelheiten näher erläutert. Dabei zeigen

Zu dem Ausführungsbeispiel nach Figur 1 gehört ein Schoner 10, der auf einen Schaft 12 aufgesteckt ist. In den Schaft 12 eingesteckt ist eine Patrone 14. Der Schaft 12 und die Patrone 14 sind gegeneinander verdrehbar, und zwar um die Längsachse des dargestellten Auftraggerätes. Die Patrone 14 trägt an ihrem Vorderende eine Auftrageinrichtung 16 mit einem Arbeitsbereich 18. Der Arbeitsbereich 18 ist über Durchgangsöffnungen mit dem Innenraum 20 der Auftrageinrichtung 16 verbunden. Eine der Durchgangsöffnungen ist beispielhaft mit der Bezugszahl 22 versehen.According to the embodiment FIG. 1 includes a schooner 10, which is attached to a shaft 12. Inserted into the shaft 12 is a cartridge 14. The shaft 12 and the cartridge 14 are rotatable relative to one another about the longitudinal axis of the illustrated applicator. The cartridge 14 carries at its front end an applicator 16 with a working area 18. The working area 18 is connected via passage openings with the interior 20 of the applicator 16. One of the passage openings is exemplified by the reference numeral 22.

In dem Schaft 12 befindet sich am hinteren Ende eine Hülse 24, die über Rippen 26, 28 mit dem Schaft 12 drehgekoppelt, bezüglich des Schaftes 12 aber axial verschieblich ist. Die Hülse 24 trägt ein Außengewinde in Form einer wendelförmigen Nut 30. An die wendelförmige Nut 30 schließt sich eine Ringnut 32 an, vgl. insbesondere Figur 1b. In die Nuten 30 bzw. 32 greifen Gewindeelemente 34, 36 ein, die an einer Hülse 38 ausgebildet sind. Die Hülse 38 ist drehfest mit der Patrone 14 gekoppelt.In the shaft 12 is located at the rear end of a sleeve 24 which is rotatably coupled via ribs 26, 28 with the shaft 12, with respect to the shaft 12 but axially displaceable. The sleeve 24 carries an external thread in the form of a helical groove 30. The helical groove 30 is followed by an annular groove 32, cf. especially FIG. 1b , In the grooves 30 and 32, threaded elements 34, 36 engage, which are formed on a sleeve 38. The sleeve 38 is rotatably coupled to the cartridge 14.

An die Hülse 24 schließt sich einstückig eine Spindel 40 an, die ein Außengewinde 42 trägt, vgl. insbesondere Figur 1b. Mit dem Außengewinde 42 kämmt ein Innengewinde 44 an einem Kolben 46.To the sleeve 24 integrally connects a spindle 40, which carries an external thread 42, see. especially FIG. 1b , With the external thread 42 meshes with an internal thread 44 on a piston 46th

Die Spindel 40 steht in einem Speicher 48, der an seiner Rückseite von dem Kolben 46 begrenzt ist und von dem Innenraum der Patrone 14 gebildet ist. Der Speicher 48 dient zur Aufnahme eines pastösen Kosmetikproduktes, wie beispielsweise Lippenrot.The spindle 40 is in a memory 48 which is bounded on its rear side by the piston 46 and is formed by the interior of the cartridge 14. The memory 48 serves to receive a pasty cosmetic product, such as lip red.

Bei der Herstellung wird zunächst die Spindel 40 mit dem daraufsitzenden Kolben 46 in die Patrone 14 eingeschoben. Daraufhin wird die Patrone 14 mit dem Kosmetikprodukt befüllt. Daher ist vor der ersten Benutzung des in Figur 1 dargestellten Auftraggerätes die Auftrageinrichtung 16 nicht mit dem Kosmetikprodukt befüllt. Vielmehr liegt vor dem Speicher 48 ein Totraum, der zunächst überwunden werden muß, um das Auftraggerät betriebsbereit zu machen.In the manufacture of the spindle 40 is first inserted with the seated piston 46 in the cartridge 14. Then, the cartridge 14 is filled with the cosmetic product. Therefore, before using the in FIG. 1 Applicator shown, the applicator 16 is not filled with the cosmetic product. Rather, in front of the memory 48 there is a dead space which must first be overcome in order to make the applicator ready for operation.

Zur Überwindung dieses Totraums dient die das Gewindeelement 34 und die wendelförmige Nut 30 aufweisende Gewindepaarung. Wird nämlich die Patrone 14 gegen den Schaft 12 verdreht, so resultiert daraus eine entsprechende Verdrehung der Hülse 38 gegenüber der Hülse 24, was wegen der axialen Fixierung der Hülse 38 bezüglich der Patrone 14 zu einer in Figur 1 aufwärts gerichteten Axialbewegung der Hülse 24 bezüglich sowohl des Schaftes 12 als auch der Patrone 14 führt. Diese Axialbewegung führt ihrerseits zu einer entsprechenden Axialbewegung des Kolbens 46, wodurch das in dem Speicher 48 befindliche Produkt unter Überwindung des Totraums in den Innenraum 20 der Fördereinrichtung 16 in Richtung Arbeitsbereich 18 gefördert wird.To overcome this dead space, the thread member 34 and the helical groove 30 having thread pairing is used. Namely, if the cartridge 14 is rotated against the shaft 12, it results in a corresponding rotation of the sleeve 38 relative to the sleeve 24, which due to the axial fixation of the sleeve 38 with respect to the cartridge 14 to a in FIG. 1 upward axial movement of the sleeve 24 with respect to both the shaft 12 and the cartridge 14 leads. This axial movement in turn leads to a corresponding axial movement of the piston 46, whereby the product located in the memory 48 is conveyed by overcoming the dead space in the interior 20 of the conveyor 16 in the direction of working area 18.

Dieser besonders geartete Mechanismus, dem immer der initiale Hub der ersten und/oder zweiten Fördereinrichtung zu eigen ist, ist besonders auch dafür geeignet, ein Dichtelement, welches den Massevorratsbehälter abdichtet, aus seiner Ruheposition zu drücken und damit den Massevorratsbehälter zu öffnen.This particular kind of mechanism, which is always the initial stroke of the first and / or second conveyor to own, is particularly suitable for pressing a sealing element which seals the bulk reservoir from its rest position and thus to open the mass reservoir.

Wie die obige Darstellung zeigt, erfolgt die Überwindung des Totraums durch Axialbewegung des Kolbens 46 sowohl bezüglich der Patrone 14 als auch bezüglich des Schaftes 12, weshalb eine Axialbewegung der Patrone 14 bezüglich des Schaftes 12 nicht stattfindet. Die Axiallänge des Auftraggerätes bleibt also während der Überwindung des Totraums erhalten.As the above diagram shows, the overcoming of the dead space by axial movement of the piston 46 takes place both with respect to the cartridge 14 and with respect to the shaft 12, for which reason an axial movement of the cartridge 14 with respect to the shaft 12 does not take place. The axial length of the applicator is thus maintained during the overcoming of the dead space.

Das gleiche gilt für den Betrieb des Auftraggerätes nach Überwindung des Totraums. Wenn nämlich die Gewindeelemente 34 und 36 an das Ende der wendelförmigen Nut 30 gelangen, laufen sie in die ringförmige Nut 32. Sobald sie in der ringförmigen Nut 32 sind, bewirkt eine Weiterverdrehung der Patrone 14 bezüglich des Schaftes 12 keine weitere Axialbewegung der Hülse 24 mehr. Vielmehr erfolgt nur noch eine Axialbewegung des Kolbens 46 bezüglich der Patrone 14, weil die Spindel 40 über die Rippen 26 und 28 mit dem Schaft 12 bezüglich der Patrone 14 verdreht wird, wohingegen der Kolben 46 bezüglich der Patrone 14 drehgekoppelt ist, beispielsweise durch eine entsprechende Vorspannung des Kolbens in der Patrone oder aufgrund von einer Kreisform abweichender Außenkontur des Kolbens und von einer Kreisform abweichender Innenkontur der Patrone, wobei insbesondere ovale Konturen in Betracht kommen. Es können aber auch entsprechende Verrippungen vorgesehen sein, beispielsweise wie im Falle der Rippen 26 und 28. Da das Außengewinde 42 und das Innengewinde 44 eine erheblich geringere Steigung haben als die wendelförmige Nut 30, erfolgt nach Überwindung des Totraums und nach dem Einlaufen der Gewindeelemente 34 und 36 in die Ringnut 32 eine Feindosierung des Kosmetikprodukts. Durch die beschriebenen Mechanismen gelangt somit das Kosmetikprodukt nach und nach von dem Speicher 48 über den Innenraum 20 und die Durchgangsöffnungen 22 in den Arbeitsbereich 18.The same applies to the operation of the applicator after overcoming the dead space. Namely, when the threaded elements 34 and 36 come to the end of the helical groove 30, they run into the annular groove 32. Once in the annular groove 32, further rotation of the cartridge 14 with respect to the shaft 12 causes no further axial movement of the sleeve 24 more , Rather, only one axial movement of the Piston 46 with respect to the cartridge 14, because the spindle 40 is rotated via the ribs 26 and 28 with the shaft 12 with respect to the cartridge 14, whereas the piston 46 is rotationally coupled with respect to the cartridge 14, for example by a corresponding bias of the piston in the cartridge or due to a circular shape deviating outer contour of the piston and of a circular shape deviating inner contour of the cartridge, in particular oval contours come into consideration. However, corresponding ribs may also be provided, for example as in the case of the ribs 26 and 28. Since the external thread 42 and the internal thread 44 have a significantly lower pitch than the helical groove 30, takes place after overcoming the dead space and after the entry of the threaded elements 34th and 36 in the annular groove 32 a fine dosage of the cosmetic product. As a result of the described mechanisms, the cosmetic product thus gradually arrives from the reservoir 48 via the interior 20 and the passage openings 22 into the working area 18.

Wenngleich dies in Figur 1 nicht dargestellt ist, so kann dennoch ein Schraubgewinde zur Kopplung des Schoners 10 mit dem Schaft 12 vorgesehen sein, bei gleichzeitiger Drehkopplung des Schoners 10 mit der Patrone 14 (beispielsweise über eine Verrippung). In einem solchen Fall würde bereits ein Abschrauben des Schoners 10 von dem Schaft 12 eine Verdrehung der Patrone 14 bezüglich des Schaftes 12 und damit eine Überwindung des oben beschriebenen Totraums mit sich bringen.Although this is in FIG. 1 not shown, it may still be a screw thread for coupling the protector 10 may be provided with the shaft 12, with simultaneous rotational coupling of the protector 10 with the cartridge 14 (for example, via a ribbing). In such a case, unscrewing the protector 10 from the shaft 12 would bring about a rotation of the cartridge 14 with respect to the shaft 12, thereby overcoming the dead space described above.

Ebenfalls in Figur 1 nicht dargestellt ist die Ausführung, bei der der Boden des Schaftes beispielsweise geöffnet ist und es somit möglich ist, durch den Druck der bloßen Finger die Hülse 24 und den daran gekoppelten Kolben um das Volumen des Totraums vorzuschieben. Dabei stoppt ein Anschlag in der Patrone nach der Überwindung des Totraums den weiteren Vorschub und das Gerät kann über die anschließende Verdrehung der beiden Stellelemente zur Feindosierung benutzt werden.Also in FIG. 1 not shown is the embodiment in which the bottom of the shaft is open, for example, and it is thus possible to advance by the pressure of the bare fingers, the sleeve 24 and the piston coupled thereto by the volume of the dead space. In this case stops a stop in the cartridge after overcoming the dead space the further feed and the device can be used on the subsequent rotation of the two control elements for fine metering.

Das Auftraggerät nach Figur 2 entspricht im wesentlichen demjenigen nach Figur 1, weshalb es nicht mehr im einzelnen erläutert wird. Vielmehr wird in dem Folgenden nur auf die Unterschiede eingegangen: Anstelle der Hülse 38 sind Arme 50, 52 vorgesehen, an denen die Gewindeelemente 34, 36 ausgebildet sind. Die Arme 50, 52 sind über Filmscharniere 54, 56 mit der Patrone 14 verbunden und können daher einstückig mit der Patrone 14 ausgebildet werden. Die Arme 50, 52 ragen durch Fenster 58, 60 in die Patrone 14 hinein, so daß die Gewindeelemente 34, 36 mit der wendelförmigen Nut 30 bzw. mit der Ringnut 32 in Eingriff kommen können.The applicator after FIG. 2 is essentially the same as that FIG. 1 why it is not explained in detail. Rather, in the following only the differences are addressed: Instead of the sleeve 38 arms 50, 52 are provided, on which the threaded elements 34, 36 are formed. The arms 50, 52 are connected via film hinges 54, 56 with the cartridge 14 and therefore can be integral with the cartridge 14th be formed. The arms 50, 52 project into the cartridge 14 through windows 58, 60 so that the threaded members 34, 36 can engage the helical groove 30 and the annular groove 32, respectively.

Die Ausgestaltung nach Figur 2 hat den Vorteil, daß die Hülse 24 in die Patrone 14 eingeschoben werden kann, ohne eingeschraubt werden zu müssen, weil erst nach dem Einschieben die Arme 50, 52 durch die Fenster 58, 60 hindurch nach innen geklappt werden.The design after FIG. 2 has the advantage that the sleeve 24 can be inserted into the cartridge 14 without having to be screwed in, because only after the insertion of the arms 50, 52 are folded through the windows 58, 60 through inside.

Außerdem kann hierdurch ein Teil eingespart werden.In addition, this can be saved a part.

Bei der Ausgestaltung nach Figur 3 hat die Hülse 24 einen im Vergleich mit den Ausgestaltungen nach den Figuren 1 und 2 größeren Durchmesser, wodurch es möglich ist, die Gewindeelemente 34, 36 unmittelbar an der Innenwand der Patrone 14 auszubilden.In the embodiment according to FIG. 3 has the sleeve 24 in comparison with the embodiments of the FIGS. 1 and 2 larger diameter, whereby it is possible to form the threaded elements 34, 36 directly on the inner wall of the cartridge 14.

Bei der Ausgestaltung nach Figur 4 ist ein Kolben 62 vorgesehen, der einstückig mit einer Spindel 64 ausgebildet ist. Mit einem in der Zeichnung nicht im einzelnen dargestellten Außengewinde auf der Spindel 64 kämmt ein Innengewinde an einem Arm 66 an der Hülse 24. Ein weiterer Arm 67 an der Hülse 24 weist kein Gewinde auf. Dadurch wird wiederum der Vorteil erreicht, daß die Spindel 64 in die Hülse 24 eingeschoben werden kann, ohne daß es eines Einschraubens bedürfte.In the embodiment according to FIG. 4 a piston 62 is provided, which is formed integrally with a spindle 64. With an external thread not shown in detail in the drawing on the spindle 64, an internal thread on an arm 66 meshes with the sleeve 24. Another arm 67 on the sleeve 24 has no thread. This in turn provides the advantage that the spindle 64 can be inserted into the sleeve 24, without the need for screwing.
