Description

Die vorliegende Erfindung betrifft eine geschlossene Portionspackung mit einem Behältnis, das eine zur Herstellung eines Getränkes, insbesondere von Kaffee, dienende Substanz enthält und einen Boden, eine Seitenwand sowie einen Deckel aufweist, wobei der Boden zur Einführung eines Extraktionsfluids in das Behältnis dient, der Deckel dazu bestimmt ist, durch mechanische Einrichtungen und/oder den Druck des Extraktionsfluids geöffnet zu werden, und die Seitenwand ausgehend von einem konischen oder zylindrischen Seitenwandabschnitt deckelseitig einen sich radial nach außen erstreckenden, als Siegelrand für den Deckel dienenden Flansch aufweist, der in einem Rollrand endet. Die Erfindung betrifft ferner eine Verpackung zur Herstellung einer geschlossenen Portionspackung.The present invention relates to a closed sachet with a container containing a substance used for the production of a beverage, in particular of coffee, and having a bottom, a side wall and a lid, the bottom serving to introduce an extraction fluid into the container, the lid is intended to be opened by mechanical means and / or the pressure of the extraction fluid, and the side wall starting from a conical or cylindrical side wall portion on the cover side has a radially outwardly extending, serving as sealing edge for the lid flange terminating in a rolling edge , The invention further relates to a package for producing a closed portion package.

Eine derartige geschlossene Portionspackung ist aus der EP 1 190 959 A1 bekannt. Die bekannte Portionspackung, die beispielsweise eine lösliche Kaffeesubstanz enthält, wird beispielsweise in eine Espressomaschine eingeführt. Der Boden der Packung wird dann über einen speziellen Öffnungsmechanismus geöffnet, indem beispielsweise Löcher in den Boden eingeprägt werden, und es wird ein Extraktionsfluid, beispielsweise Wasser/Wasserdampf, unter hohem Druck durch die Löcher in das Behältnis eingeführt. Die sich im Behältnis befindende Kaffeesubstanz löst sich im Extraktionsfluid, und der Deckel der Packung wird durch den Druck des Extraktionsfluids aufgerissen. Der austretende Kaffee wird dann von einem Trinkgefäß aufgefangen.Such a closed portion package is from the EP 1 190 959 A1 known. The known sachet containing, for example, a soluble coffee substance is introduced, for example, in an espresso machine. The floor The package is then opened via a special opening mechanism, for example, by embossing holes in the bottom, and an extraction fluid, such as water / water vapor, is introduced under high pressure through the holes into the container. The coffee substance in the container dissolves in the extraction fluid, and the lid of the package is torn open by the pressure of the extraction fluid. The escaping coffee is then collected from a drinking vessel.

Während der Zubereitung des Kaffees dichtet eine Dichtung innerhalb der Espressomaschine das Maschinensystem unter hohem Druck zum Behältnis ab. Diese Dichtung unterliegt jedoch einem ständigen Verschleiß und verschmutzt auf Dauer gesehen. Dies führt zur Verschmutzung der gesamten Maschine.During the preparation of the coffee, a seal within the espresso machine seals the machine system under high pressure to the container. However, this seal is subject to constant wear and dirty in the long run. This leads to contamination of the entire machine.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine geschlossene Portionspackung der angegebenen Art zu schaffen, die sich auf besonders saubere Weise handhaben lässt.The present invention has for its object to provide a closed portion package of the specified type, which can be handled in a particularly clean manner.

Diese Aufgabe wird erfindungsgemäß bei einer geschlossenen Portionspackung der eingangs wiedergegebenen Art dadurch gelöst, dass das Behältnis mit einem Dichtring versehen ist, der unterhalb des Seitenwandflansches zwischen dem konischen oder zylindrischen Seitenwandabschnitt und dem Rollrand angeordnet ist.This object is achieved in a closed portion pack of the type reproduced by the fact that the container is provided with a sealing ring which is disposed below the Seitenwandflansches between the conical or cylindrical side wall portion and the rolled edge.

Bei der erfindungsgemäßen Lösung wird somit auf eine Dichtung innerhalb der Getränkezubereitungsmaschine (Kaffee- bzw. Espressomaschine) verzichtet. Die Aufgabe der Abdichtung des Maschinensystems wird auf die Portionspackung selbst übertragen, die erfindungsgemäß mit einem Dichtring versehen ist, der die zur Abdichtung in der Getränkezubereitungsmaschine (Kaffee- bzw. Espressomaschine) vorgesehene Dichtung ersetzt oder zusätzlich zu einer derartigen Dichtung vorgesehen ist. Da die Dichtung an der Portionspackung selbst angebracht ist, handelt es sich um eine Einmaldichtung, die nach der Zubereitung des Getränkes zusammen mit dem Behältnis entsorgt wird. Es besteht somit keine Gefahr, dass die Dichtung durch mehrmaligen Gebrauch verschleißt oder verschmutzt.In the solution according to the invention is thus dispensed with a seal within the beverage preparation machine (coffee or espresso machine). The task of sealing of the machine system is transferred to the sachet itself, which is provided according to the invention with a sealing ring which replaces the seal provided for sealing in the beverage preparation machine (coffee or espresso machine) or is provided in addition to such a seal. Since the seal is attached to the sachet itself, it is a disposable seal that is discarded along with the container after the beverage has been prepared. There is thus no risk that the seal wears or dirty by repeated use.

Der erfindungsgemäß vorgesehene Dichtring wird vorzugsweise nach der Abfüllung und Versiegelung der Portionspackung am Behältnis befestigt, so dass er nicht den bei Abfüllung und Versiegelung der Portionspackung auftretenden hohen Temperaturen ausgesetzt ist. Eine Beschädigung des Dichtringes durch das Abfüllen und Versiegeln (Aufbringen des Deckels) der Portionspackung tritt daher nicht auf. Insbesondere ein Aufschmelzen des Dichtringes beim Abfüllen und Versiegeln findet daher nicht statt.The inventively provided sealing ring is preferably attached to the container after filling and sealing the sachet, so that it is not exposed to the high temperatures occurring during filling and sealing of the sachet. Damage to the sealing ring by the filling and sealing (application of the lid) of the sachet therefore does not occur. In particular, a melting of the sealing ring during filling and sealing therefore does not take place.

Die kurzzeitig bei der Getränkezubereitung durch die Einführung des Extraktionsfluids auftretenden Temperaturen bewirken keine Beschädigung des Dichtringes.The temperatures occurring briefly during the preparation of the beverage by the introduction of the extraction fluid cause no damage to the sealing ring.

Vorzugsweise ist der Dichtring mechanisch am Behältnis befestigt, insbesondere durch Festklemmen. Der Dichtring weist hierbei zweckmäßigerweise einen etwas geringeren Innendurchmesser als der Außendurchmesser des konischen oder zylindrischen deckelseitigen Seitenwandabschnittes des Behältnisses auf, so dass sich der gewünschte Klemmeffekt ergibt.Preferably, the sealing ring is mechanically attached to the container, in particular by clamping. The sealing ring expediently has a slightly smaller inner diameter than the outer diameter of the conical or cylindrical cover-side side wall section of the container on, so that the desired clamping effect results.

Bei einer anderen Ausführungsform der Erfindung ist der Dichtring am Behältnis festgeklebt. Hierfür kann beispielsweise ein Heißschmelzkleber oder eine Selbstklebebeschichtung Verwendung finden. Kombinationen zwischen einer mechanischen Befestigung und einer Verklebung sind ebenfalls möglich.In another embodiment of the invention, the sealing ring is glued to the container. For this example, a hot melt adhesive or a self-adhesive coating can be used. Combinations between a mechanical attachment and a bond are also possible.

Bei noch einer anderen Ausführungsform ist der Dichtring durch Vorsprünge am konischen oder zylindrischen Seitenwandabschnitt des Behältnisses fixiert. Diese Vorsprünge bzw. Ausstülpungen, die radial von der Seitenwand vorstehen, wirken als Widerlager für den Dichtring und verhindern, dass sich dieser nach unten vom Seitenwandflansch löst.In yet another embodiment, the sealing ring is fixed by protrusions on the conical or cylindrical side wall portion of the container. These projections, which protrude radially from the side wall, act as an abutment for the sealing ring and prevent it from coming off the side wall flange downwards.

Der Dichtring ist erfindungsgemäß unterhalb des Seitenwandflansches zwischen dem konischen oder zylindrischen Seitenwandabschnitt und dem Rollrand am radialen Ende des Seitenwandflansches angeordnet. Der Dichtring füllt dabei vorzugsweise den gesamten Raum zwischen dem Rollrand und dem konischen oder zylindrischen Seitenwandabschnitt aus. Dies schließt nicht aus, dass der Dichtring auch nur einen Teil dieses Raumes ausfüllen kann.The sealing ring is arranged according to the invention below the Seitenwandflansches between the conical or cylindrical side wall portion and the rolling edge at the radial end of the Seitenwandflansches. The sealing ring preferably fills the entire space between the rolled edge and the conical or cylindrical side wall portion. This does not exclude that the sealing ring can fill only a part of this space.

Der erfindungsgemäß vorgesehene Dichtring kann auf Portionspackungen aufgebracht werden, die im Stand der Technik bekannt sind. Hierzu müssen keine Portionspackungen mit neuen geometrischen Formen entwickelt werden. Natürlich kann die erfindungsgemäße Lösung aber auch bei neuentwickelten Portionspackungen Anwendung finden. Erfindungsgemäß sind alle Portionspackungen geeignet, bei denen die Seitenwand ausgehend von einem konischen oder zylindrischen Seitenwandabschnitt deckelseitig einen sich radial nach außen erstreckenden, als Siegelrand für den Deckel dienenden Flansch aufweist, der in einem Rollrand endet.The inventively provided sealing ring can be applied to sachets, which are known in the art. For this, no portion packs with new geometric shapes need to be developed. Naturally However, the solution according to the invention can also find application in newly developed portion packs. According to the invention, all portion packages are suitable in which, starting from a conical or cylindrical side wall portion, the side wall has a flange which extends radially outwards and serves as a sealing edge for the lid, which ends in a rolled edge.

In der Regel besitzen die bekannten Behältnisse von Portionspackungen einen Rollrand mit einer 1/3-Rollung. Dieser Rollrand kann erfindungsgemäß vergrößert werden, um ein größeres Widerlager für den Dichtring zu bilden. So weist bei einer Ausführungsform der Erfindung der Rollrand eine vergrößerte, insbesondere eine halbe oder eine ganze, Rollung auf. Der Rollrand erstreckt sich daher bei dieser Ausführungsform weiter nach unten und vergrößert somit die seitliche Begrenzung bzw. den entsprechenden Anschlag für den Dichtring. Ferner kann der Rollrand im Durchschnitt auch oval ausgebildet sein oder andere Formen besitzen.In general, the known containers of sachets have a rolled edge with a 1/3 roll. This roll edge can be increased according to the invention to form a larger abutment for the sealing ring. Thus, in one embodiment of the invention, the rolled edge on an enlarged, in particular a half or a whole, rolling on. Therefore, in this embodiment, the rolled edge extends further downwards and thus increases the lateral boundary or the corresponding stop for the sealing ring. Furthermore, the rolled edge may on average also be oval or have other shapes.

Bei einer weiteren Ausführungsform der Erfindung ist die Seitenwand des Behältnisses konisch ausgebildet und weist im zum Seitenwandflansch benachbarten Bereich einen zylindrischen Abschnitt auf. Bei dieser Ausführungsform kontaktiert daher der Dichtring keinen konischen, sondern einen zylindrischen Seitenwandabschnitt. Auch diese Maßnahme kann zur Verbesserung der Befestigung des Dichtringes dienen.In a further embodiment of the invention, the side wall of the container is conical and has a cylindrical portion in the region adjacent to the side wall flange. In this embodiment, therefore, the sealing ring contacted no conical, but a cylindrical side wall portion. This measure can also serve to improve the attachment of the sealing ring.

Bei noch einer weiteren Ausführungsform der Erfindung besitzt der Dichtring einen zum konischen oder zylindrischen Seitenwandabschnitt weisenden Kragen. Mit Kragen ist hier ein im montierten Zustand des Dichtringes etwa parallel zum entsprechenden Seitenwandabschnitt verlaufender Dichtringabschnitt gemeint. Durch den Kragen wird eine besonders enge Anpassung an den entsprechenden Seitenwandabschnitt des Behältnisses erreicht. Der Kragen kann flexibel ausgebildet sein, so dass er beim Aufsetzen des Dichtringes aus einer etwa horizontalen Lage in die Lage etwa parallel zum Seitenwandabschnitt verformt wird. Eine mehr oder weniger starre Ausgestaltung des Kragens ist natürlich auch möglich.In still another embodiment of the invention, the sealing ring has a collar facing the conical or cylindrical side wall portion. With collar is here A meant in the mounted state of the sealing ring approximately parallel to the corresponding side wall portion extending sealing ring portion. By the collar a particularly close adaptation to the corresponding side wall portion of the container is achieved. The collar may be flexible, so that it is deformed when placing the sealing ring from an approximately horizontal position in the position approximately parallel to the side wall portion. A more or less rigid design of the collar is of course also possible.

Der Dichtring kann ferner an seiner radialen Außenseite abgeschrägt sein, um eine bessere Anpassung an den Rollrand zu erreichen. Hierdurch wird insbesondere ein besseres Einklinken in den Rollrand ermöglicht.The sealing ring may also be chamfered on its radially outer side in order to achieve a better adaptation to the rolled edge. As a result, in particular a better latching in the rolled edge is made possible.

Was die für die Portionspackung verwendeten Materialien anbetrifft, so sind diese dem Fachmann bekannt. Für das Behältnis kommen Aluminium oder geeignete Kunststoffe zur Anwendung, während der Deckel beispielsweise aus einer Aluminiumfolie besteht. Der erfindungsgemäß vorgesehene Dichtring kann generell aus den für Dichtungen bzw. Dichtringe verwendeten bekannten Materialien bestehen, die entsprechende elastische Eigenschaften aufweisen. Hierfür sind entsprechende Elastomere geeignet.As far as the materials used for the portion pack are concerned, these are known to the person skilled in the art. For the container aluminum or suitable plastics are used, while the lid consists for example of an aluminum foil. The inventively provided sealing ring may generally consist of the known materials used for seals or sealing rings, which have corresponding elastic properties. Suitable elastomers are suitable for this purpose.

Bei einer besonders bevorzugten Ausführungsform besteht der Dichtring aus geschäumtem Kunststoff oder weist eine Schicht aus geschäumtem Kunststoff auf. Dieses Material ist ausreichend verformbar, um die geforderten Dichtungseigenschaften zu erfüllen. Es können dabei geschlossenzellige oder offenzellige Kunststoffschaummaterialien Verwendung finden. In der Regel kann der Dichtring insgesamt aus geschäumtem Kunststoff bestehen. Sollte ein solcher Dichtring nicht die geforderten Stabilitätseigenschaften aufweisen, wird er mit einer stabilisierenden Trägerschicht versehen, die beispielsweise aus einem stabilitätsverleihenden Kunststoff besteht und die Schicht aus geschäumtem Kunststoff trägt. Eine solche Trägerschicht kann auch beidseitig mit einer Schicht aus geschäumtem Kunststoff versehen sein.In a particularly preferred embodiment, the sealing ring made of foamed plastic or has a layer of foamed plastic. This material is sufficiently deformable to meet the required sealing properties. It can be closed cell or open-cell plastic foam materials are used. As a rule, the sealing ring can consist entirely of foamed plastic. If such a sealing ring does not have the required stability properties, it is provided with a stabilizing carrier layer, which consists for example of a stability-imparting plastic and carries the layer of foamed plastic. Such a carrier layer can also be provided on both sides with a layer of foamed plastic.

Was die Dicke des erfindungsgemäß vorgesehenen Dichtringes betrifft, so hat dieser vorzugsweise eine Dicke von 100-1.000 µm. Entsprechende Dicken können je nach Anwendungsfall ausgewählt werden.As far as the thickness of the sealing ring provided according to the invention is concerned, this preferably has a thickness of 100-1,000 μm. Corresponding thicknesses can be selected depending on the application.

Vorstehend wurde erwähnt, dass der Dichtring nach dem Verfüllen des Behältnisses und der Aufbringung des Deckels auf die Portionspackung aufgebracht wird. Dies stellt in der Regel die Endstufe bei der Produktion der Portionspackung dar. Eine andere Lösung der Erfindung sieht vor, dass der Dichtring erst vom Konsumenten nach Kauf einer Portionspackung auf diese aufgebracht wird, beispielsweise kurz vor dem Einführen der Portionspackung in eine Getränkezubereitungsmaschine. Für diese Lösung sieht die Erfindung eine Verpackung zur Herstellung einer geschlossenen, mit einem Dichtring versehenen Portionspackung vor, bei der der Dichtring in die Verpackung integriert und durch Lösen desselben von der Verpackung auf dem Behältnis unterhalb von dessen Seitenwandflansch befestigbar ist. Dies kann beispielsweise so geschehen, dass der Verbraucher beim Entnehmen der Portionspackung aus der Verpackung die Portionspackung durch den innerhalb bzw. an der Verpackung befestigten Dichtring drückt, so dass dieser auf das Behältnis aufgeschoben wird. Natürlich sind auch andere Ausgestaltungen möglich.It was mentioned above that the sealing ring is applied to the sachet after filling the container and applying the lid. This is usually the final stage in the production of the sachet. Another solution of the invention provides that the sealing ring is not applied to the consumer until after purchasing a sachet, for example, just before inserting the sachet into a beverage preparation machine. For this solution, the invention provides a package for producing a closed, provided with a sealing ring portion package, in which the sealing ring is integrated into the package and by releasing the same from the packaging on the container below its Seitenwandflansch can be fastened. This can for example be done so that the consumer when removing the sachet from the package, the sachet presses through the sealing ring mounted inside or on the packaging, so that it is pushed onto the container. Of course, other configurations are possible.

Eine derartige Verpackung ist beispielsweise so ausgebildet, dass der Dichtring auf einer von der Verpackung gebildeten Abstützung aufliegt und Deckel und Rollrand des Behältnisses auf dem Dichtring aufliegen, wobei durch Druckausübung auf den Deckel des Behältnisses der Dichtring von der Abstützung gelöst wird und in seine Dichtungsposition innerhalb des Seitenwandflansches gelangt. Dabei bildet der Dichtring vorzugsweise einen Teil einer Dichtungsmaterialbahn und weist zum Lösen von der Materialbahn eine Sollbruchstelle auf. Es versteht sich, dass diese Materialbahn zweckmäßigerweise eine Vielzahl von nebeneinander angeordneten und über Verbindungsabschnitte verbundenen Dichtringen aufweist, wobei in die Dichtringe die entsprechenden Behältnisse eingesetzt sind. Die Dichtungsmaterialbahn, die Behältnisse sowie die entsprechenden Abstützungen sind vorzugsweise von einer geeigneten Umverpackung umgeben. Nach Öffnen der Umverpackung kann somit durch Druckausübung auf den Deckel eines Behältnisses dieses unter Ablösung eines Dichtringes von der Dichtungsmaterialbahn zwischen den Abstützungen nach unten aus der Verpackung herausgedrückt werden.Such a package is formed, for example, so that the sealing ring rests on a support formed by the packaging and rest lid and roll edge of the container on the sealing ring, being released by applying pressure to the lid of the container, the sealing ring of the support and in its sealing position within the Seitenwandflansches passes. In this case, the sealing ring preferably forms part of a sealing material web and has a predetermined breaking point for releasing from the material web. It is understood that this material web expediently has a plurality of juxtaposed and connected via connecting portions sealing rings, wherein in the sealing rings, the corresponding containers are used. The sealing material web, the containers and the corresponding supports are preferably surrounded by a suitable outer packaging. After opening the outer packaging can thus be pushed out by exerting pressure on the lid of a container under detachment of a sealing ring of the sealing material web between the supports down from the packaging.

Figur 1 zeigt eine erste Ausführungsform einer mit einem Dichtring 10 versehenen geschlossenen Portionspackung 1 im Vertikalschnitt. Die Portionspackung 1 besitzt ein Behältnis 4, das eine zur Herstellung eines Getränkes dienende Substanz (nicht gezeigt) enthält. Das Behältnis hat einen Boden 5, eine konische Seitenwand 6 und einen Deckel 3. Die konische Seitenwand 6 weist deckelseitig einen sich radial nach außen erstreckenden, als Siegelrand für den Deckel 3 dienenden Flansch 20 auf, der in einem Rollrand 2 endet. Der Rollrand 2 erstreckt sich in Bezug auf den Flansch 20 nach oben und nach unten und besitzt bei dem hier dargestellten Beispiel eine 1/3-Rollung. FIG. 1 shows a first embodiment of a provided with a sealing ring 10 closed portion package 1 in vertical section. The sachet 1 has a container 4 containing a substance (not shown) for making a beverage. The container has a bottom 5, a conical side wall 6 and a lid 3. The conical side wall 6 has on the lid side a radially outwardly extending, serving as sealing edge for the lid 3 flange 20, which ends in a rolled edge 2. The rolled edge 2 extends with respect to the flange 20 up and down and has in the example shown here a 1/3 roll.

Die vorstehend beschriebene Portionspackung 1 ist bekannt und befindet sich im Handel. Gemäß der Erfindung ist das Behältnis 4 der Portionspackung zusätzlich mit einem Dichtring 10 versehen, der unterhalb des Seitenwandflansches 20 zwischen dem konischen oder zylindrischen Seitenwandabschnitt und dem Rollrand 2 angeordnet ist. Dieser Dichtring 10 besteht aus geschäumtem Kunststoff und hat eine Dicke von 1.000 µm. Geeignete Kunststoffe sind beispielsweise PE, PP, PA, PET, PVC oder vorzugsweise PS. Der Dichtring 10 ist mechanisch am Behältnis durch Klemmung zwischen Rollrand 2 und Seitenwand 6 befestigt. Anstelle oder zusätzlich zu einer rein mechanischen Befestigung kann der Dichtring 10 auch mit der Unterseite des Seitenwandflansches 20 verklebt sein.The portion pack 1 described above is known and is commercially available. According to the invention, the container 4 of the sachet is additionally provided with a sealing ring 10, which is arranged below the side wall flange 20 between the conical or cylindrical side wall portion and the rolled edge 2. This sealing ring 10 is made of foamed plastic and has a thickness of 1,000 microns. Suitable plastics are, for example, PE, PP, PA, PET, PVC or preferably PS. The sealing ring 10 is mechanically fastened to the container by clamping between rolled edge 2 and side wall 6. Instead of or in addition to a purely mechanical attachment of the sealing ring 10 may be bonded to the underside of the side wall flange 20.

Figur 2 zeigt eine weitere Ausführungsform einer geschlossenen Portionspackung im Vertikalschnitt. Im Unterschied zur Packung der Figur 1 ist hierbei die Seitenwand 6 des Behältnisses 4 anders ausgebildet. Diese Seitenwand 6 ist nicht bis zum Deckel durchlaufend konisch ausgebildet, wie in Figur 1 gezeigt, sondern weist deckelseitig einen zylindrischen Abschnitt 7 auf, der sich an einen unteren konischen Abschnitt anschließt. Der zylindrische Abschnitt 7 mündet im Seitenwandflansch 20, der wiederum im Rollrand 2 endet. Auch hier ist ein Dichtring 10 zwischen Rollrand 2 und Seitenwand 6 des Behältnisses befestigt, wobei der Dichtring gegen den zylindrischen Seitenwandabschnitt 7 stößt. FIG. 2 shows a further embodiment of a closed portion package in vertical section. Unlike the pack of FIG. 1 Here, the side wall 6 of the container 4 is formed differently. This side wall 6 is not continuously conical up to the lid, as in FIG. 1 but has on the cover side a cylindrical portion 7, which adjoins a lower conical portion. The cylindrical portion 7 opens into the side wall flange 20, which in turn ends in the rolling edge 2. Again, a sealing ring 10 is secured between rolling edge 2 and side wall 6 of the container, wherein the sealing ring abuts against the cylindrical side wall portion 7.

Bei der in Figur 3 im Vertikalschnitt gezeigten Ausführungsform einer geschlossenen Portionspackung 1 entspricht das Behältnis 4 der in Figur 1 dargestellten Ausführungsform. Zusätzlich sind hierbei um den Umfang der Seitenwand 6 herum Vorsprünge (Ausstülpungen) 11 vorgesehen, die als Widerlager für den an der Unterseite des Seitenwandflansches 20 vorgesehenen Dichtring 10 dienen und verhindern, dass sich der Dichtring 10 nach unten löst.At the in FIG. 3 shown in vertical section embodiment of a closed portion package 1 corresponds to the container 4 in FIG. 1 illustrated embodiment. In addition, in this case projections (protuberances) 11 are provided around the circumference of the side wall 6, which serve as an abutment for the provided on the underside of the Seitenwandflansches 20 sealing ring 10 and prevent the sealing ring 10 dissolves down.

Vier verschiedene Ausführungsformen des Dichtringes 10 sind in Figur 4 im Vertikalschnitt dargestellt. Bei der in Figur 4a gezeigten Ausführungsform ist der Dichtring 10 vollständig aus geschäumtem Kunststoff ausgebildet, beispielsweise geschäumtem PS. Bei der in Figur 4b gezeigten Ausführungsform weist der Dichtring eine mittlere Trägerschicht 12 zur Stabilisierung sowie eine obere Schicht 10 und eine untere Schicht 13 aus geschäumtem Kunststoff auf. Bei einer nichtgezeigten Ausführungsform besitzt der Dichtring eine obere und untere Trägerschicht sowie eine mittlere Schicht aus geschäumtem Kunststoff. Je nach Stabilisierungsanforderungen sind hier diverse Kombinationen möglich.Four different embodiments of the sealing ring 10 are in FIG. 4 shown in vertical section. In the embodiment shown in Figure 4a, the sealing ring 10 is formed entirely of foamed plastic, such as foamed PS. In the embodiment shown in FIG. 4b, the sealing ring has a middle carrier layer 12 for stabilization, as well as an upper layer 10 and a lower layer 13 of foamed plastic. In a not shown embodiment, the sealing ring has an upper and lower carrier layer and a middle layer of foamed plastic. Depending on the stabilization requirements, various combinations are possible here.

Figur 4c zeigt eine Ausführungsform eines Dichtringes 10, die mit einem sich von einem Ende schräg nach unten erstreckenden Kragen 14 versehen ist. Beim Aufschieben des Dichtringes 10 auf das Behältnis schmiegt sich der Kragen 14 eng an den zugehörigen Seitenwandabschnitt an bzw. wird durch diesen in eine Schrägstellung bzw. senkrechte Stellung verformt, so dass ein festes Aufsitzen auf der Seitenwand erreicht wird.FIG. 4 c shows an embodiment of a sealing ring 10 which is provided with a collar 14 which extends obliquely downward from one end. When sliding the sealing ring 10 onto the container, the collar 14 snugly fits against the associated side wall section or is deformed by the latter into an inclined position or vertical position, so that a firm seating on the side wall is achieved.

Figur 4d zeigt eine Ausführungsform, bei der der Dichtring 10 an seinem radial äußeren Ende abgeschrägt ist, wie bei 15 gezeigt, um ein besseres Einklinken am Rollrand 2 zu ermöglichen.FIG. 4 d shows an embodiment in which the sealing ring 10 is chamfered at its radially outer end, as shown at 15, in order to enable a better engagement on the rolled edge 2.

Figur 5 zeigt eine schematische Seitenansicht einer Portionspackungen 1 enthaltenden Verpackung 22. Die Verpackung 22 besitzt eine geeignete Umverpackung 21, innerhalb der sich eine Vielzahl von Portionspackungen 1 befindet, die in der vorstehend beschriebenen Weise ausgebildet, jedoch noch nicht mit dem Dichtring versehen sind. Stattdessen sind die Portionspackungen 1 in die Löcher einer durchlaufenden Materialbahn 24 eingesetzt, die entsprechende Dichtringe 10 enthält, welche über Sollbruchstellen 26 mit dem restlichen Teil der Dichtungsmaterialbahn 24 verbunden sind. Diese Dichtungsmaterialbahn 24 liegt auf Abstützungen 23 auf, so dass die einzelnen Portionspackungen 1 in einer hängenden Lage innerhalb der Verpackung angeordnet sind. Dabei stützen sich die Rollränder 2 der Portionspackungen 1 über die Dichtungsmaterialbahn 24 auf seitlich vorstehenden Flanschen 27 der Abstützungen 23 ab. Bei 25 sind entsprechende Öffnungen vorgesehen, durch die die Portionspackungen 1 aus der Verpackung herausgedrückt werden können. FIG. 5 shows a schematic side view of a portion packaging 1 containing package 22. The package 22 has a suitable outer packaging 21, within which there is a plurality of sachets 1, which are formed in the manner described above, but not yet provided with the sealing ring. Instead, the portion packs 1 are inserted into the holes of a continuous material web 24, which contains corresponding sealing rings 10 which are connected via predetermined breaking points 26 with the remaining part of the sealing material web 24. This sealing material web 24 rests on supports 23, so that the individual portion packs 1 are arranged in a hanging position within the packaging. The rolling edges 2 of the portion packs 1 are supported on the sealing material web 24 on laterally projecting flanges 27 of the supports 23 from. At 25 corresponding openings are provided through which the sachets 1 can be pushed out of the package.

Bei Benutzung der Verpackung 22 wird die Umverpackung 21 geöffnet. Durch Druckausübung auf den Deckel 3 wird die Portionspackung 1 nach unten aus der Verpackung herausgedrückt, wobei sich der zugehörige Dichtring 10 über die Sollbruchstelle 26 von der Dichtungsmaterialbahn 24 löst und in seine Dichtungsposition an der Unterseite des Seitenflansches 20 der Portionspackung gelangt. Die mit dem Dichtungsring versehene Portionspackung 1 gelangt dann nach unten über die Öffnung 25 aus der Verpackung heraus.When using the package 22, the outer package 21 is opened. By applying pressure to the lid 3, the sachet 1 is pushed down out of the package, with the associated sealing ring 10 over the predetermined breaking point 26 of the sealing material web 24 dissolves and in its sealing position on the underside of the side flange 20 of the portion pack arrives. The provided with the sealing ring portion package 1 then passes down through the opening 25 out of the package.
