Abstract

The unit has two partial units (2, 3) with two receptacles (5, 6) that receive a cosmetic substance and a closure cap (7, 8). The partial units are inter-connected by a coupling member (4), where the coupling member comprises a central portion with two axial coupling projections. The coupling projection engages with a cap recess when the projection prevails in an assembled state. A longitudinal hollow space extends in an axial direction along the coupling projection of the coupling member.

Description

Die Erfindung betrifft eine Kosmetikeinheit umfassend zwei Teileinheiten mit jeweils einem Vorratsbehälter zur Aufnahme einer kosmetischen Substanz und einer Verschlusskappe, mittels dessen der Vorratsbehälter verschließbar ist, wobei die beiden Teileinheiten mittels eines an den beiden Verschlusskappen angreifenden Kupplungsteils miteinander verbindbar sind und jede Verschlusskappe an einer von dem Vorratsbehälter der zugehörigen Teileinheit abgewandten axialen Stirnseite eine sich in Richtung einer Mittenachse erstreckende Kappenausnehmung aufweist.The invention relates to a cosmetic unit comprising two subunits each having a reservoir for receiving a cosmetic substance and a closure cap, by means of which the reservoir is closable, wherein the two subunits are connectable to each other by means of a coupling part acting on the two caps and each cap on one of the Reservoir of the associated subunit facing away from the axial end face has a extending in the direction of a central axis cap recess.

Eine derartige Kosmetikeinheit ist beispielsweise aus der EP 1 348 352 B1 bekannt. In die beiden schraubverschließbaren Vorratsbehälter können gleiche oder unterschiedliche Kosmetika, wie z.B. Nagellack, Wimperntusche, Lidschatten, Lipgloss oder Mittel zum Entfernen des- bzw. derselben, eingefüllt sein. Bei der bekannten Kosmetikeinheit sind die Verschlusskappe und das als Kupplungshülse ausgeführte Kupplungsteil mittels einer axial verlaufenden Verzahnung und mittels einer zusätzlich vorgesehenen Rastnut-Rastwulst-Verbindung lösbar miteinander verbunden. Die Verzahnung bewirkt eine Drehfestigkeit, die Rastnut-Rastwulst-Verbindung eine axiale Festigkeit der Verbindung. Es sind also zwei verschiedene, unabhängig voneinander wirkende Verbindungsmechamsmen vorgesehen. Dies führt zu einem relativ hohen Fertigungsaufwand.Such a cosmetic unit is for example from the EP 1 348 352 B1 known. The two screw-lockable storage containers can be filled with the same or different cosmetics, such as, for example, nail polish, mascara, eye shadow, lip gloss or means for removing the same. In the known cosmetic unit, the closure cap and the coupling part designed as a coupling part are detachably connected to each other by means of an axially extending toothing and by means of an additionally provided locking groove Rastwulst connection. The toothing causes a torsional strength, the detent groove Rastwulst connection axial strength of the connection. So there are two different, independently acting Verbindungsmechamsmen provided. This leads to a relatively high production cost.

Gleiches gilt für die Herstellung der Verschlusskappen, die von der Kupplungshülse übergriffen werden und deshalb in diesem Bereich mit einem vergleichsweise kleinen Außendurchmesser ausgeführt werden müssen. Zugleich befindet sich aber genau in diesem Bereich auch die Verbindung zwischen der Verschlusskappe und dem jeweiligen Applikatorstiel, so dass für die Wanddicke der Verschlusskappen nur wenig Platz zur Verfügung steht. Die Fertigung muss deshalb sehr genau durchgeführt werden.The same applies to the production of the closure caps, which are overlapped by the coupling sleeve and therefore must be performed in this area with a comparatively small outer diameter. At the same time, however, the connection between the closure cap and the respective applicator stem is located precisely in this region, so that only little space is available for the wall thickness of the closure caps. The production must therefore be carried out very accurately.

Soll eine unterschiedliche Befüllung der beiden Teileinheiten und deren unterschiedlicher Verwendungszweck bei der Kosmetikeinheit gemäß der EP 1 348 352 B1 von außen zu erkennen sein, erfolgt dies z.B. durch eine spezielle graphische oder farbliche Gestaltung der Kupplungshülse. Dabei ist für jede mögliche Befüllungskombination eine anders gestaltete Kupplungshülse vorzusehen. Diese Vielfalt an verschiedenen Kupplungshülsen führt ebenfalls zu höheren Fertigungskosten.If a different filling of the two subunits and their different purpose in the cosmetic unit according to the EP 1 348 352 B1 be recognized from the outside, this is done for example by a special graphic or color design of the coupling sleeve. In this case, a differently shaped coupling sleeve is to be provided for each possible filling combination. This variety of different coupling sleeves also leads to higher production costs.

Die Kosmetikeinheit gemäß der EP 1 348 352 B1 hat vor allem bei aufgesetzter Kupplungshülse ein ansprechendes äußeres Erscheinungsbild. Ist die Kupplungshülse dagegen abgezogen, gilt dies nur noch mit Einschränkungen, da dann die durch die genannten Verbindungsmechanismen bestimmte Außenkontur der Verschlusskappe zum Vorschein kommt.The cosmetic unit according to the EP 1 348 352 B1 has an appealing external appearance, especially with attached coupling sleeve. If, however, the coupling sleeve is pulled off, this only applies with restrictions, because then the outer contour of the closure cap, which is determined by the aforementioned connection mechanisms, becomes apparent.

In der US 6,035,865 A wird eine Kosmetikeinheit beschrieben, die zwei Teileinheiten mit jeweils einem Vorratsbehälter zur Aufnahme einer kosmetischen Substanz und einer Verschlusskappe umfasst. Im Boden dieser Vorratsbehälter sind Ausnehmungen vorgesehen, in die Kupplungsvorsprünge eines Kupplungsteils eingreifen, um die beiden Teileinheiten miteinander zu verbinden.In the US 6,035,865 A a cosmetic unit is described which comprises two subunits, each with a reservoir for receiving a cosmetic substance and a cap. In the bottom of this reservoir recesses are provided, engage in the coupling projections of a coupling part to connect the two subunits with each other.

Die Aufgabe der Erfindung besteht nun darin, eine Kosmetikeinheit der eingangs bezeichneten Art anzugeben, bei der die beiden Teileinheiten in einfacher Weise und insbesondere mit geringem Fertigungsaufwand miteinander verbindbar sind.The object of the invention is therefore to provide a cosmetic unit of the type described, in which the two subunits are connected to each other in a simple manner and in particular with little manufacturing effort.

Zur Lösung dieser Aufgabe wird eine Kosmetikeinheit entsprechend den Merkmalen des Patentanspruchs 1 angegeben. Bei der erfindungsgemäßen Kosmetikeinheit umfasst das Kupplungsteil einen Mittenabschnitt mit zwei angeformten axialen Kupplungsvorsprüngen, wobei jeder Kupplungsvorsprung im zusammengesetzten Zustand in eine der beiden Kappenausnehmungen eingreift, und in dem Kupplungsvorsprung des Kupplungsteils ein sich in axialer Richtung erstreckender Längshohlraum vorgesehen ist. Der erfindungsgemäß vorgesehene Verbindungsmechanismus mit dem in die Kappenausnehmung eingreifenden Kupplungsvorsprung ist einfach zu realisieren und herzustellen. Dennoch bietet er eine gute Verbindungsfestigkeit zwischen dem Kupplungsteil und der jeweiligen Verschlusskappe.To solve this problem, a cosmetic unit according to the features of claim 1 is given. In the cosmetic unit according to the invention, the coupling part comprises a central portion with two molded axial coupling projections, wherein each coupling projection engages in the assembled state in one of the two Kappenausnehmungen, and in the coupling projection of the coupling part is provided in the axial direction extending longitudinal cavity. The inventively provided connection mechanism with the engaging in the cap recess coupling projection is easy to implement and manufacture. Nevertheless, it offers a good connection strength between the coupling part and the respective cap.

Bei der erfindungsgemäßen Kosmetikeinheit ist außerdem in einfacher und kostengünstiger Weise eine Kennzeichnung der Befüllung jeder Teileinheit möglich, ohne dass dazu eine große Vielfalt verschiedener Kupplungsteile vorgesehen werden müsste. Die Kennzeichnung kann durch eine entsprechende graphische oder farbliche Gestaltung der Verschlusskappen erfolgen. Die Verschlusskappen sind aufgrund des erfindungsgemäß vorgesehenen Verbindungsmechanismus insbesondere auch im zusammengesetzten Zustand sichtbar und können damit zur Kennzeichnung der Befüllung der jeweiligen Teileinheit verwendet werden. Außerdem können die im zusammengesetzten Zustand sichtbaren Außenumfangsflächen der Verschlusskappen gemäß den jeweils gewünschten ästhetischen Anforderungen ausgebildet werden. Sie haben vorteilhafterweise für den Verbindungsmechanismus keine Funktion zu erfüllen. So können die Verschlusskappen bei der erfindungsgemäßen Kosmetikeinheit insbesondere optisch ansprechende glatte und/oder hochglänzende Außenumfangsflächen aufweisen.In the case of the cosmetic unit according to the invention, moreover, a marking of the filling of each subunit is possible in a simple and cost-effective manner, without the need for a large variety of different coupling parts. The marking can be done by a corresponding graphical or color design of the caps. Because of the connection mechanism provided according to the invention, the closure caps are also visible in the assembled state and can thus be used to identify the filling of the respective subunit. In addition, the outer peripheral surfaces of the closure caps, which are visible in the assembled state, can be formed according to the respective desired aesthetic requirements. They advantageously have no function to fulfill for the connection mechanism. Thus, the closure caps in the cosmetic unit according to the invention can in particular have visually appealing smooth and / or high-gloss outer peripheral surfaces.

Vorteilhafte Ausgestaltungen der erfindungsgemäßen Kosmetikeinheit ergeben sich aus den Merkmalen der von Anspruch 1 abhängigen Ansprüche.Advantageous embodiments of the cosmetic unit according to the invention emerge from the features of the claims dependent on claim 1.

Günstig ist eine Variante, bei der in dem Kupplungsvorsprung außerdem auch ein quer zur axialen Richtung verlaufender Querhohlraum vorgesehen ist. Diese Hohlräume erhöhen die Elastizität des Kupplungsvorsprungs. Er lässt sich so leichter in die Kappenausnehmung einführen. Außerdem verbessert sich so der Anpressdruck des eingeführten Kupplungsvorsprungs an die Innenwand der Kappenausnehmung.Conveniently, a variant in which in the coupling projection also also a transverse transverse to the axial direction transverse cavity is provided. These cavities increase the elasticity of the coupling projection. It is easier to insert into the cap recess. In addition, so improves the contact pressure of the inserted coupling projection on the inner wall of the Kappenausnehmung.

Bei einer günstigen Ausgestaltung ist an einer Innenwand der Kappenausnehmungen ein Rastvorsprung vorgesehen, der im zusammengesetzten Zustand in den Querhohlraum eingreift. So lässt sich sehr einfach eine ggf. auch wieder lösbare Schnappverbindung zwischen dem Kupplungsteil und der jeweiligen Verschlusskappe realisieren. Eine lösbare Verbindung hat außerdem den Vorteil, dass nicht nur der industrielle Hersteller und/oder Befüller der Teileinheiten das Zusammenfügen zu der doppelteiligen Kosmetikeinheit vornehmen kann. Dies kann dann auch im Einzelhandel oder sogar erst durch die Endverbraucherin erfolgen.In a favorable embodiment, a latching projection is provided on an inner wall of the Kappenausnehmungen, which engages in the assembled state in the transverse cavity. This makes it very easy to realize a possibly also releasable snap connection between the coupling part and the respective closure cap. A detachable connection also has the advantage that not only the industrial manufacturer and / or filler of the subunits can make the assembly to the double-piece cosmetic unit. This can then be done in retail or even by the end user.

Vorzugsweise kann weiterhin zwischen dem Kupplungsvorsprung und der Verschlusskappe eine Klebeverbindung vorgesehen sein. So ist eine insbesondere nicht mehr lösbare Verbindung zwischen dem Kupplungsteil und der jeweiligen Verschlusskappe gebildet. Die in den Kupplungsvorsprüngen insbesondere vorgesehenen Längs- und Querhohlräume können dann einerseits als anfängliches Reservoir für ein Klebemittel dienen, von dem aus das Klebemittel im zusammengesetzten Zustand zwischen die einander gegenüberliegenden Wandbereiche des jeweiligen Kupplungsvorsprungs und der jeweiligen Verschlusskappe gelangt. Andererseits können die genannten Hohlräume aber auch zur Aufnahme von überschüssigem Klebemittel dienen, das vor dem Zusammensetzen in die Kappenausnehmung eingebracht wird.Preferably, furthermore, an adhesive connection can be provided between the coupling projection and the closure cap. Thus, a particular no longer detachable connection between the coupling part and the respective closure cap is formed. The longitudinal and transverse cavities provided in the coupling projections, on the one hand, can on the one hand serve as an initial reservoir for an adhesive, from which the adhesive in the assembled state passes between the mutually opposite wall regions of the respective coupling projection and the respective closure cap. On the other hand, the said cavities can also serve to receive excess adhesive, which is introduced into the cap recess prior to assembly.

Gemäß einer anderen vorteilhaften Variante ist der Kupplungsvorsprung im zusammengesetzten Zustand mittels eines Presssitzes innerhalb der Kappenausnehmung angeordnet. Damit kann eine lösbare Verbindung zwischen dem Kupplungsteil und der jeweiligen Verschlusskappe gebildet werden.According to another advantageous variant of the coupling projection is in the assembled state by means of a press fit within the Cap recess arranged. Thus, a releasable connection between the coupling part and the respective closure cap can be formed.

Insbesondere hat der Kupplungsvorsprung außerdem einen eckigen, abgerundeten, ovalen oder runden Querschnitt. Ein runder Querschnitt erleichtert das Zusammenfügen des Kupplungsteils und der jeweiligen Verschlusskappe, da keine Vorzugsrichtung zu beachten ist. Die übrigen genannten Querschnittsvarianten sind dagegen nicht vollständig rotationssymmetrisch. Sie ermöglichen eine besonders drehfeste Verbindung zwischen dem Kupplungsteil und der jeweiligen Verschlusskappe. Dies ist vor allem dann von Vorteil, wenn die Verschlusskappe auf den Vorratsbehälter aufgeschraubt ist Beim Auf- oder Abschrauben der Verschlusskappe auf den bzw. von dem Vorratsbehälter kann sich dann die Verbindung zwischen dem Kupplungsteil und den Verschlusskappen nicht lösen.In particular, the coupling projection also has a polygonal, rounded, oval or round cross-section. A round cross-section facilitates the assembly of the coupling part and the respective closure cap, since no preferential direction is to be considered. By contrast, the other cross-sectional variants mentioned are not completely rotationally symmetrical. They allow a particularly rotationally fixed connection between the coupling part and the respective cap. This is particularly advantageous when the cap is screwed onto the reservoir When screwing or unscrewing the cap on or from the reservoir then the connection between the coupling part and the caps can not solve.

Weiterhin hat das Kupplungsteil in Übergangsbereichen von dem Mittenabschnitt zu dem jeweiligen Kupplungsvorsprung insbesondere einen eckigen, abgerundeten oder ovalen Querschnitt. Auch wenn ein solcher Querschnitt insbesondere nur in dem Übergangsbereich vorgesehen ist, lässt sich eine drehfeste Verbindung zwischen dem Kupplungsteil und der jeweiligen Verschlusskappe bilden.Furthermore, the coupling part in transition regions from the central portion to the respective coupling projection in particular has a polygonal, rounded or oval cross-section. Even if such a cross section is provided in particular only in the transition region, a rotationally fixed connection between the coupling part and the respective closure cap can be formed.

Gemäß einer anderen günstigen Ausgestaltung nimmt ein Flächeninhalt von Querschnittsflächen in den Übergangsbereichen ausgehend von dem Mittenabschnitt kontinuierlich ab und eine sich in Richtung der Mittenachse erstreckende Außenkontur hat in den Übergangsbereichen vorzugsweise einen gewölbten, insbesondere durch einen Längsradius bestimmten Verlauf Dies erleichtert das Zusammensetzen des Kupplungsteils mit den Teileinheiten. Außerdem ist die abgerundete Optik ästhetisch ansprechend.According to another advantageous embodiment, a surface area of cross-sectional areas in the transition areas decreases continuously starting from the center section, and an outer contour extending in the direction of the center axis preferably has a curved course in the transition areas, in particular a longitudinal radius This facilitates the assembly of the coupling part with the subunits. In addition, the rounded look is aesthetically pleasing.

Bei einer weiteren bevorzugten Variante hat jeder der Kupplungsvorsprünge an seinem freien Ende mindestens einen quer zur axialen Richtung verlaufenden und sich über die gesamte Querabmessung erstreckenden Quer schlitz. Insbesondere können zwei oder vier solcher Querschlitze vorgesehen sein, die dann vorzugsweise über den Querschnitt gleichmäßig verteilt angeordnet sind. Dadurch wird die Elastizität der Kupplungsvorsprünge verbessert. Dies ist vor allem bei Schnappverbindungen mit den Verschlusskappen günstig.In a further preferred variant, each of the coupling projections at its free end at least one transverse to the axial direction and extending over the entire transverse dimension transverse slot. In particular, two or four such transverse slots may be provided, which are then preferably distributed uniformly over the cross section. As a result, the elasticity of the coupling projections is improved. This is especially favorable for snap connections with the caps.

Außerdem ist es günstig, wenn jeder der Kupplungsvorsprünge an seinem freien Ende mindestens zwei durch den Querschlitz voneinander getrennte Stege hat und an einer Außenseite mindestens eines Stegs ein Rastvorsprung vorgesehen ist. So lässt sich besonders einfach eine Schnappverbindung mit den Verschlusskappen herstellen. Der Rastvorsprung schnappt in eine korrespondierende Rastvertiefung in der jeweiligen Kappenausnehmung ein.Moreover, it is advantageous if each of the coupling projections has at least two webs which are separated from one another by the transverse slot at its free end, and a latching projection is provided on an outer side of at least one web. This makes it particularly easy to make a snap connection with the caps. The latching projection snaps into a corresponding latching depression in the respective cap recess.

Gemäß einer weiteren vorteilhaften Ausgestaltung weist der Mittenabschnitt zwei axiale Stirnseiten und eine äußere Umfangsfläche auf und zwischen jeder der Stirnseiten und der äußeren Umfangsfläche ist jeweils ein umlaufender abgerundeter Rand vorhanden. Dadurch ergeben sich im Kontaktbereich zwischen den Verschlusskappen und dem Mittenabschnitt glatte Konturen, die sich angenehm anfühlen. So wird ein scharfer und damit verletzungsträchtiger Rand vermieden. Außerdem ist die abgerundete Optik ästhetisch ansprechend.According to a further advantageous embodiment, the middle section has two axial end faces and an outer peripheral face and between each of the end faces and the outer circumferential face there is in each case a circumferential rounded edge. This results in the contact area between the caps and the center section smooth contours that feel comfortable. This avoids a sharp and thus injury-prone edge. In addition, the rounded look is aesthetically pleasing.

Bei einer anderen ebenfalls vorteilhaften Ausgestaltung weist der Mittenabschnitt zwei axiale Stirnseiten und eine äußere Umfangsfläche auf und zwischen jeder der Stirnseiten und der äußeren Umfangsfläche ist jeweils ein umlaufender Rand vorhanden, der mit einem axial vorstehenden Randüberstand versehen ist Dadurch sind die Kontaktbereiche zwischen den Verschlusskappen und dem Mittenabschnitt jeweils praktisch übergangslos und spaltfrei ausgestaltet.In another likewise advantageous embodiment, the center section has two axial end faces and an outer peripheral surface and between each of the end faces and the outer peripheral surface is in each case a peripheral edge provided which is provided with an axially projecting edge supernatant Thereby, the contact areas between the closure caps and the Center section each designed virtually seamless and gap-free.

Einander entsprechende Teile sind in den Fig. 1 bis 13 mit denselben Bezugszeichen versehen.Corresponding parts are in the Fig. 1 to 13 provided with the same reference numerals.

In Fig. 1 ist ein Ausführungsbeispiel einer aus Kunststoff hergestellten Kosmetikeinheit 1 gezeigt. Sie umfasst zwei Teileinheiten 2 und 3, die mittels eines Kupplungsteils 4 miteinander verbunden sind. Bei dem Ausführungsbeispiel gemäß Fig. 1 ist diese Verbindung lösbar ausgestaltet. Grundsätzlich ist aber auch eine andere Ausgestaltung, beispielsweise als nicht lösbare Klebeverbindung, möglich.In Fig. 1 an embodiment of a cosmetic unit 1 made of plastic is shown. It comprises two subunits 2 and 3, which are interconnected by means of a coupling part 4. In the embodiment according to Fig. 1 this connection is detachable. In principle, however, another embodiment, for example as a non-detachable adhesive connection, possible.

Die Teileinheiten 2 und 3 enthalten jeweils einen Vorratsbehälter 5 bzw. 6, der mittels einer beispielsweise aufschraubbaren Verschlusskappe 7 bzw. 8 dicht verschließbar ist. In den Vorratsbehältern 5 und 6 befindet sich jeweils eine kosmetische Substanz, in die ein an die jeweilige Verschlusskappe 7 oder 8 angeformter Stiel 9 bzw. 10 eintaucht. Die in die Vorratsbehältern 5 und 6 eingefüllten Kosmetika können sich voneinander unterscheiden. Beim Ausführungsbeispiel ist die Teileinheit 2 mit einer Mascaraflüssigkeit und die Teileinheit 3 mit einem Nagellack befüllt. An dem eingetauchten Stielende ist ein in Fig. 1 nur schematisch dargestellter Applikator 9a bzw. 10a, wie z.B. ein Mascarabürstchen bzw. ein Nagellackpinsel, angebracht.The sub-units 2 and 3 each contain a reservoir 5 and 6, which is tightly closed by means of a screw-on cap 7 and 8, for example. In each of the storage containers 5 and 6 there is a cosmetic substance into which a stem 9 or 10 molded onto the respective closure cap 7 or 8 is inserted. The filled in the reservoirs 5 and 6 cosmetics may differ from each other. In the exemplary embodiment, the subunit 2 is filled with a mascara liquid and the subunit 3 is filled with a nail varnish. At the dipped end of the stem is an in Fig. 1 only schematically illustrated applicator 9a and 10a, such as a mascara brush or a nail polish brush attached.

In Fig. 2 ist die Kosmetikeinheit 1 in nur teilweise zusammengefügtem Zustand und in Fig. 3 das unmontierte Kupplungsteil 4 gezeigt. Das Kupplungsteil 4 hat einen zylindrischen Mittenabschnitt 11 mit zwei axialen, d.h. in Richtung einer Mittenachse 12 der Kosmetikeinheit 1 weisenden, Kupplungsvorsprüngen 13 und 14. Letztere sind konzentrisch zu der Mittenachse 12 an jeweils einer der beiden axialen Stirnseiten des Mittenabschnitts 11 angeformt. Sie bilden Zapfen.In Fig. 2 is the cosmetic unit 1 in only partially assembled state and in Fig. 3 the unmounted coupling part 4 is shown. The coupling part 4 has a cylindrical central portion 11 with two axial, ie pointing in the direction of a central axis 12 of the cosmetic unit 1, coupling projections 13 and 14. The latter are concentric with the central axis 12 formed on each of the two axial end sides of the central portion 11. They form cones.

Dementsprechend haben die Verschlusskappen 7 und 8 an ihrer vom jeweils zugehörigen Vorratsbehälter 5 bzw. 6 abgewandten axialen Stirnseite eine in Fig. bis 3 nicht näher gezeigte, sich in axialer Richtung erstreckende Kappenausnehmung. Im zusammengesetzten Zustand greifen die Kupplungsvorsprünge 13 und 14 in eine dieser Kappenausnehmungen ein.Accordingly, the closure caps 7 and 8 have on their side facing away from the respectively associated reservoir 5 and 6, axial end face not shown in detail in Fig. To 3, extending in the axial direction Kappenausnehmung. In the assembled state, the coupling projections 13 and 14 engage in one of these cap recesses.

Die Querschnittskonturen der Kappenausnehmung und der Kupplungsvorsprünge 13 und 14 sind aneinander angepasst. Sie sind im Wesentlichen gleich. Die Kupplungsvorsprünge 13 und 14 haben aber im nicht eingesteckten Zustand eine etwas größere Querschnittsfläche als die Kappenausnehmungen, so dass im eingesteckten Zustand ein Presssitz mit guter Verbindungsfestigkeit erreicht wird.The cross-sectional contours of the cap recess and the coupling projections 13 and 14 are adapted to each other. They are essentially the same. However, the coupling projections 13 and 14 have a slightly larger cross-sectional area than the cap recesses in the uninstalled state, so that in the inserted state an interference fit with good connection strength is achieved.

Jeder der Kupplungsvorsprünge 13 und 14 hat einen konzentrischen Längshohlraum 15 bzw. 16, der sich von der freien axialen Stirnseite des jeweiligen Kupplungsvorsprungs 13 bzw. 14 ausgehend axial in den jeweiligen Kupplungsvorsprung 13 bzw. 14 erstreckt. Dabei kann es sich um zwei Sackbohrungen oder um eine durch das ganze Kupplungsteil 4 hindurch gehende Durchgangsbohrung handeln. Die Längshohlräume 15 und 16 erhöhen die Elastizität der Kupplungsvorsprünge 13 und 14, so dass sie sich leichter in die Kappenausnehmungen einstecken lassen. Diese erhöhte Elastizität erlaubt auch die vorstehend beschriebene etwas größere Querschnittsfläche der Kupplungsvorsprünge 13 und 14, die vorteilhafterweise einen sehr starken Anpressdruck an die Innenwand der Kappenausnehmungen bewirkt.Each of the coupling projections 13 and 14 has a concentric longitudinal cavity 15 and 16, respectively, extending from the free axial end of the respective Coupling projection 13 and 14 extending axially into the respective coupling projection 13 and 14, respectively. This can be two blind holes or a through hole passing through the entire coupling part 4. The longitudinal cavities 15 and 16 increase the elasticity of the coupling projections 13 and 14, so that they can be easily inserted into the cap recesses. This increased elasticity also allows the above-described slightly larger cross-sectional area of the coupling projections 13 and 14, which advantageously causes a very strong contact pressure against the inner wall of the Kappenausnehmungen.

Jeder Kupplungsvorsprung 13 oder 14 hat außerdem einen Querhohlraum 17 bzw. 18, der quer zur Mittenachse 12 durch den betreffenden Kupplungsvorsprung 13 bzw. 14 verläuft. Die Länge dieser beim Ausführungsbeispiel als runde Durchgangsbohrungen ausgeführten Querhohlräume 17 und 18 ist gleich dem Durchmesser der Kupplungsvorsprünge 13 und 14. Die Längshohlräume 15 bzw.16 und die Querhohlräume 17 bzw. 18 des jeweiligen Kupplungsvorsprungs 13 oder 14 kreuzen sich und sind miteinander verbunden. An den ansonsten hohlzylindrischen Innenwänden der Kappenausnehmungen sind korrespondierende teilkugelförmige Rastvorsprünge vorgesehen, die im zusammengefügten Zustand der Kosmetikeinheit 1 in die Querhohlräume 17 und 18 einschnappen, wodurch die Festigkeit der Verbindung sowohl in axialer als auch in tangentialer Richtung erhöht wird.Each coupling projection 13 or 14 also has a transverse cavity 17 and 18 which extends transversely to the central axis 12 by the respective coupling projection 13 and 14, respectively. The length of this executed in the embodiment as round through holes transverse cavities 17 and 18 is equal to the diameter of the coupling projections 13 and 14. The longitudinal cavities 15 and16 and the transverse cavities 17 and 18 of the respective coupling projection 13 or 14 intersect and are interconnected. On the otherwise hollow cylindrical inner walls of the Kappenausnehmungen corresponding part-spherical locking projections are provided which snap in the assembled state of the cosmetic unit 1 in the transverse cavities 17 and 18, whereby the strength of the compound is increased both in the axial and in the tangential direction.

Das Kupplungsteil 4 ist spiegelsymmetrisch bezüglich einer Querschnittsebene, die an der axialen Mitte des Mittenabschnitts 11 quer durch den Mittenabschnitt 11 verläuft. Außerdem ist es abgesehen von den Querhohlräumen 17 und 18 rotationssymmetrisch bezüglich der Mittenachse 12.The coupling part 4 is mirror-symmetrical with respect to a cross-sectional plane which extends transversely through the middle section 11 at the axial center of the middle section 11. Moreover, apart from the transverse cavities 17 and 18, it is rotationally symmetric with respect to the center axis 12.

Weiterhin ist die Außenkontur des Mittenabschnitts 11 an eine AuBenkontur der Verschlusskappen 7 und 8 bzw. der Teileinheiten 2 und 3 insgesamt angepasst. Beim Ausführungsbeispiel haben die Teileinheiten 2 und 3 sowie der Mittenabschnitt 11 jeweils im Wesentlichen zylindrische Außenumfangsflächen mit in etwa gleichen Zylinderradien. Dadurch ergeben sich ein ansprechendes Erscheinungsbild und eine gute Handhabung. Der im zusammengesteckten Zustand sicht- und spürbare Mittenabschnitt 11 des Kupplungsteils 4 fügt sich optisch und haptisch sehr gut in die Kosmetikeinheit 1 ein.Furthermore, the outer contour of the middle section 11 is adapted to an outer contour of the closure caps 7 and 8 or the subunits 2 and 3 as a whole. In the exemplary embodiment, the subunits 2 and 3 and the center section 11 each have substantially cylindrical outer circumferential surfaces with approximately equal cylinder radii. This results in an attractive appearance and good handling. The visible and palpable in the assembled state center portion 11 of the coupling part 4 fits visually and haptically very well in the cosmetic unit 1 a.

Dieselben Wirkungen werden durch eine weitere vorteilhafte konstruktive Maßnahme an dem Mittenabschnitt 11 hervorgerufen. Der Mittenabschnitt 11 hat zwei axiale Stirnseiten 19 und 20, zwischen denen sich eine äußere Umfangsfläche 21 erstreckt. An den beiden zwischen jeder der Stirnseiten 19 und 20 einerseits und der Umfangsfläche 21 andererseits gebildeten umlaufenden Kanten ist jeweils eine Abrundung vorgesehen, so dass jeweils ein umlaufender abgerundeter Rand 22 bzw. 23 vorhanden ist. Dadurch hat die Kosmetikeinheit 1 im zusammengesetzten Zustand eine besonders glatte und sich angenehm anfühlende Außenkontur, die keine scharfen und verletzungsträchtigen Übergangszonen zwischen den Teileinheiten 2 und 3 und dem Mittenabschnitt 11 des Kupplungsteils 4 aufweist.The same effects are caused by a further advantageous constructional measure at the center section 11. The center section 11 has two axial end faces 19 and 20, between which an outer peripheral surface 21 extends. At the two between each of the end faces 19 and 20 on the one hand and the peripheral surface 21 on the other hand formed circumferential edges a rounding is provided in each case, so that in each case a circumferential rounded edge 22 and 23 is present. As a result, the cosmetic unit 1 in the assembled state has a particularly smooth and pleasantly pleasant outer contour, which has no sharp and injury-resistant transition zones between the subunits 2 and 3 and the middle section 11 of the coupling part 4.

Aufgrund der vorstehend beschriebenen günstigen Ausgestaltung der Kosmetikeinheit 1 mit dem Kupplungsteil 4 ist es möglich, die Vorratsbehälter 5 und 6 herstellerseitig gesondert und unabhängig voneinander mit konventionellen Maschinen zu befüllen und zu handhaben. Die Verschlusskappen 7 und 8 werden ebenfalls mit vorhandenen Maschinen wie konventionelle Schraubkappen aufgeschraubt. Die so hergestellten Teileinheiten 2 und 3 sind individuell lager- und transportierbar. Sie können zu einem beliebigen Zeitpunkt zu der Kosmetikeinheit 1 zusammengefügt werden. Dies kann beim Hersteller oder beim Händler - bei letzterem insbesondere sogar erst aufgrund des jeweiligen Kundenwunsches - erfolgen. Hierzu ist nur ein einfaches axiales Aufstecken von beiden Seiten auf das gemeinsame Kupplungsteil 4 erforderlich.Due to the above-described favorable embodiment of the cosmetic unit 1 with the coupling part 4, it is possible to fill the reservoir 5 and 6 manufacturer separately and independently with conventional machines and handle. The caps 7 and 8 are also screwed with existing machines such as conventional screw caps. The subunits 2 and 3 thus produced are individually storable and transportable. They can be assembled at any time to the cosmetic unit 1. This can be done by the manufacturer or the dealer - in the latter case, in particular, only on the basis of the respective customer request. For this purpose, only a simple axial plugging on both sides of the common coupling part 4 is required.

Für den praktischen Gebrauch kann die jeweils nicht benutzte Teileinheit 2 bzw. 3 zusammen mit der über das Kupplungsteil 4 (dreh-)fest angebundenen Verschlusskappe 8 bzw. 7 von dem Vorratsbehälter 6 bzw. 5 mit der zu benutzenden kosmetischen Substanz abgeschraubt werden und dabei als eine Art Griff dienen, der eine besonders einfache Handhabung ermöglicht.For practical use, the respectively unused subunit 2 or 3 can be unscrewed together with the over the coupling part 4 (rotating) firmly attached cap 8 and 7 of the reservoir 6 and 5 with the cosmetic substance to be used and thereby serve a kind of handle, which allows a particularly simple handling.

Wenn einer der Vorratsbehälter 5 und 6 leer ist, braucht nicht die gesamte Kosmetikeinheit 1 weggeworfen zu werden. Vielmehr kann die leere Teileinheit 2 oder 3 durch eine neue ersetzt werden. Hierzu ist nur die Steckverbindung am Kupplungsteil 4 zu lösen. Die noch funktionsfähige, ganz oder teilweise gefüllte Teileinheit 3 oder 2 kann dann mit einer neuen Teileinheit 2 oder 3 kombiniert werden, wobei entweder die ursprüngliche Kombination der Kosmetikeinheit 1 wiederhergestellt oder je nach Wunsch der Verbraucherin eine neue Kombination geschaffen werden kann.If one of the storage containers 5 and 6 is empty, it is not necessary to throw away the entire cosmetic unit 1. Rather, the empty subunit 2 or 3 can be replaced by a new one. For this purpose, only the connector on the coupling part 4 is to be solved. The still functional, completely or partially filled subunit 3 or 2 can then be combined with a new subunit 2 or 3, whereby either the original combination of the cosmetic unit 1 can be restored or a new combination can be created as desired by the consumer.

Die in Fig. 4 bis 12 gezeigten weiteren Ausfuhrungsbeispiele von Kupplungsteilen, mittels derer sich ebenfalls Doppel-Kosmetikeinheiten vergleichbar der aus den Teileinheiten 2 und 3 lösbar zusammengesetzten Kosmetikeinheit 1 bilden lassen, haben im Wesentlichen die gleichen vorteilhaften Wirkungen wie das vorstehend beschriebene Kupplungsteil 4 der Kosmetikeinheit 1.In the 4 to 12 shown further exemplary embodiments of coupling parts, by means of which also double-cosmetic units can be formed comparable to the detachable from the subunits 2 and 3 cosmetic unit 1, have substantially the same advantageous effects as the above-described coupling part 4 of the cosmetic unit. 1

In Fig. 4 und 5 ist ein Kupplungsteil 24 gezeigt, das sich von dem Kupplungsteil 4 gemäß Fig. 1 bis 3 in erster Linie durch zusätzlich vorgesehene Übergangsbereiche 25 und 26 zwischen dem Mittenabschnitt 11 und dem jeweiligen Kupplungsvorsprung 13 bzw, 14 unterscheidet. Die Übergangs-, bereiche 25 und 26 haben jeweils eckige Querschnittsflächen, deren Flächeninhalt ausgehend von den Stirnseiten 19 bzw. 20 des Mittenabschnitts 11 kontinuierlich abnimmt und deren Form schließlich in die runde Querschnittsgeometrie mündet, die der jeweilige Kupplungsvorsprung 13 bzw. 14 an einem seinem freien Ende zugewandten Endbereich hat. Die vier in jedem der Übergangsbereiche 25 und 26 aufgrund des eckigen Querschnitts gebildeten Eckkanten 27 (siehe hierzu auch Fig. 11) verlaufen in axialer Richtung mit einer konvexen Wölbung. Diese gewölbte Kontur der Eck kanten 27 ist durch einen Längsradius R1 bestimmt. Die Übergangsbereiche 25 und 26 korrespondieren mit entsprechend ausgeformten Querschnittskonturen in den Kappenausnehmungen der in Fig. 4 und 5 nicht gezeigten beiden Teileinheiten, aus denen eine Doppel-Kosmetikeinheit mittels des Kupplungsteils 24 zusammengefügt werden kann. Die eckige Querschnittskontur in den Übergangsbereichen 25 und 26 bewirkt dann eine drehfeste Verbindung zwischen dem Kupplungsteil 24 und der jeweiligen Verschlusskappe der beiden Teileinheiten.In 4 and 5 a coupling part 24 is shown extending from the coupling part 4 according to Fig. 1 to 3 primarily by additionally provided transition regions 25 and 26 between the central portion 11 and the respective coupling projection 13 and 14, respectively. The transition areas 25 and 26 each have polygonal cross-sectional areas, the area of which decreases continuously starting from the end faces 19 and 20 of the middle section 11 and finally opens their shape in the round cross-sectional geometry, the respective coupling projection 13 and 14 at one of its free End facing end portion has. The four corner edges 27 formed in each of the transition regions 25 and 26 due to the angular cross-section (see also Fig. 11 ) extend in the axial direction with a convex curvature. This curved contour of the corner edges 27 is determined by a longitudinal radius R 1 . The transition regions 25 and 26 correspond with correspondingly shaped cross-sectional contours in the cap recesses of FIG 4 and 5 not shown two subunits, from which a double-cosmetic unit can be joined together by means of the coupling part 24. The angular cross-sectional contour in the transition regions 25 and 26 then causes a rotationally fixed connection between the coupling part 24 and the respective closure cap of the two subunits.

In Fig. 6 und 7 ist ein weiteres Kupplungsteil 28 gezeigt, bei dem im Vergleich zu dem Kupplungsteil 24 gemäß Fig. 4 und 5 anders ausgestaltete Kupplungsvorsprünge 29 und 30 vorgesehen sind. Anstelle der Längshohlräume 15 und 16 sowie der Querhohlräume 17 und 18 haben die Kupplungsvorsprünge 29 und 30 des Kupplungsteils 28 an ihrem jeweiligen freien axialen Ende zwei quer zur Richtung der Mittensachse 12 verlaufende Querschlitze 31 und 32. Letztere erstrecken sich über die gesamte Querabmessung, also über die gesamte Durchmesserlänge, des jeweiligen Kupplungsvorsprungs 29 oder 30. Sie sind senkrecht zueinander angeordnet, so dass an dem freien Ende des Kupplungsvorsprungs 29 oder 30 jeweils vier gleich große und in Umfangsrichtung gleich verteilte Materialstege 33 gebildet sind. Die Querschlitze 31 und 32 trennen die Materialstege 33 voneinander. Ähnlich wie die Längshohlräume 15 und 16 der Kupplungsvorsprünge 13 und 14 erhöhen auch die Querschlitze 31 und 32 die Elastizität der Kupplungsvorsprünge 29 und 30, so dass ein leichteres Einstecken in die Kappenausnehmungen ermöglicht wird.In 6 and 7 a further coupling part 28 is shown, in which compared to the coupling part 24 according to FIG 4 and 5 differently configured coupling projections 29 and 30 are provided. Instead of the longitudinal cavities 15 and 16 and the transverse cavities 17 and 18, the coupling projections 29 and 30 of the coupling part 28 at its respective free axial end two transversely to the direction of the central axis 12 extending transverse slots 31 and 32. The latter extend over the entire transverse dimension, that is about the entire diameter length of each Coupling projection 29 or 30. They are arranged perpendicular to each other, so that at the free end of the coupling projection 29 or 30 each four equal and circumferentially equally distributed material webs 33 are formed. The transverse slots 31 and 32 separate the material webs 33 from each other. Similar to the longitudinal cavities 15 and 16 of the coupling projections 13 and 14, the transverse slots 31 and 32 also increase the elasticity of the coupling projections 29 and 30, thus allowing for easier insertion into the cap recesses.

In Fig. 8 und 9 ist ein weiteres Kupplungsteil 34 mit dem Mittenabschnitt 11 und Kupplungsvorsprüngen 35 und 36 gezeigt. Jeder der Kupplungsvorsprünge 35 und 36 hat ähnlich wie die Kupplungsvorsprünge 29 und 30 an seinem freien Ende vier durch die Querschlitze 31 und 32 voneinander getrennte Materialstege 37. Im Unterschied zu den Materialstegen 33 sind die Materialstege 37 an ihrer jeweiligen Außenseite mit einem Rastvorsprung 38 versehen. Die Rastvorsprünge 38 greifen im zusammengefügten Zustand einer in Fig. 8 und 9 nicht näher dargestellten Kosmetikeinheit in korrespondierende Ausnehmungen an den Innenwänden der Kappenausnehmungen ein, so dass eine Schnappverbindung gebildet wird, die aufgrund der Elastizität der Materialstege 37 auch wieder gelöst werden kann.In 8 and 9 a further coupling part 34 with the center portion 11 and coupling projections 35 and 36 is shown. Each of the coupling projections 35 and 36 has, similar to the coupling projections 29 and 30 at its free end four separated by the transverse slots 31 and 32 material webs 37. In contrast to the material webs 33, the material webs 37 are provided on their respective outer side with a locking projection 38. The locking projections 38 engage in the assembled state of a 8 and 9 Cosmetic unit not shown in corresponding recesses on the inner walls of the Kappenausnehmungen, so that a snap connection is formed, which can be solved due to the elasticity of the material webs 37 again.

In Fig. 10 und 11 ist ein weiteres Kupplungsteil 39 gezeigt, das im Wesentlich ähnlich aufgebaut ist wie das Kupplungsteil 34, sich aber von allen Kupplungsteilen 4, 24, 28 und 34 durch einen anders ausgestalteten Mit tenabschnitt 40 unterscheidet. Anstelle der an den Stossstellen zwischen den Stirnseiten 19 und 20 und der äußeren Umfangsfläche 21 umlaufenden abgerundeten Ränder 22 und 23 hat der Mittenabschnitt 40 an diesen Bereichen jeweils einen umlaufenden Rand mit einem axial vorstehenden Randüberstand 41 bzw. 42. Im zusammengefügten Zustand einer in Fig. 10 und 11 wiederum nicht näher dargestellten Kosmetikeinheit übergreifen die Randüberstände 41 und 42 den äußeren Umfangsrand am axialen Ende der Verschlusskappen, so dass die Kontaktbereiche zwischen den Verschlusskappen und dem Mittenabschnitt 40 jeweils praktisch übergangslos und spaltfrei sind.In 10 and 11 a further coupling part 39 is shown, which is constructed substantially similar to the coupling part 34, but differs from all the coupling parts 4, 24, 28 and 34 by a differently designed with tenabschnitt 40. Instead of at the abutting points between the end faces 19 and 20 and the outer peripheral surface 21 encircling rounded edges 22 and 23 of the middle portion 40 at these areas each have a peripheral edge with an axially projecting edge projection 41 and 42. In the assembled state of a Fig. 10 and 11 in turn not shown in detail cosmetic unit overlap the edge projections 41 and 42, the outer peripheral edge at the axial end of the caps, so that the contact areas between the caps and the middle portion 40 are each practically seamless and gap-free.

In Fig. 12 und 13 ist ein weiteres Kupplungsteil 43 gezeigt, das einen Mittenabschnitt 44 mit umlaufenden Randüberständen 45 und 46 ausweist, die sich ähnlich wie die Randüberstände 41 und 42 bei dem Mittenabschnitt 40 des Kupplungsteils 39 gemäß Fig.10 und 11 an den Stirnseiten 19 bzw. 20 axial in Richtung des jeweiligen Kupplungsvorsprungs 35 bzw. 36 erstrecken und damit ebenfalls ein übergangsloses und spaltfreies Zusammenfügen mit den Verschlusskappen ermöglichen. Im Unterschied zu der äußeren Umfangsfläche 21 der Mittenabschnitte 11 und 40, die eine leicht konvexe Vorwölbung in radialer Richtung aufweist, hat der Mittenabschnitt 44 eine äußere Umfangsfläche 47 mit einer konkaven Wölbung.In FIGS. 12 and 13 a further coupling part 43 is shown, which has a central portion 44 with peripheral edge projections 45 and 46, which are similar to the edge projections 41 and 42 at the central portion 40 of the coupling part 39 according to FIG Fig.10 and 11 extend at the end faces 19 and 20 axially in the direction of the respective coupling projection 35 and 36 and thus also allow a seamless and gap-free assembly with the caps. Unlike the outer peripheral surface 21 of the middle portions 11 and 40, which has a slightly convex protrusion in the radial direction, the center portion 44 has an outer peripheral surface 47 with a concave curvature.
