Description

Die Erfindung betrifft eine Baugruppe aus einem Foliengebinde zur Aufbewahrung einer ein- oder mehrkomponentigen Masse und einer Auspressvorrichtung für das Foliengebinde, wobei das Foliengebinde wenigstens einen nicht eigensteif ausgebildeten länglichen Folienbeutel sowie ein eigensteifes Kopfteil mit zumindest einem Befestigungsabschnitt für ein Ende des Folienbeutels und einer Austrittsöffnung für den Austritt der Masse aufweist und wobei die Auspressvorrichtung wenigstens eine Aufnahme zum Einschieben des wenigstens einen Folienbeutels aufweist.The invention relates to an assembly of a film container for storing a one-component or multi-component mass and a squeezing device for the film package, wherein the film package at least one non-rigid inherent elongated film bag and an inherently rigid head part with at least one attachment portion for one end of the film bag and an outlet opening for having the outlet of the mass and wherein the squeezing device has at least one receptacle for insertion of the at least one film bag.

Derartige Foliengebinde haben sich in der Vergangenheit als Verpackung für chemische Massen wie beispielsweise Mörtel-, Schaum-, Dübel- oder Dichtmassen bewährt, die aus einer oder mehreren Komponenten bestehen. Insbesondere gegenüber Kartuschen zeichnen sie sich durch eine kostengünstigere und einfachere Herstellung sowie einen geringeren nach der Nutzung zu entsorgenden Materialanteil aus.Such film packages have been proven in the past as packaging for chemical compositions such as mortar, foam, dowel or sealants, which consist of one or more components. Especially with respect to cartridges they are characterized by a cheaper and easier production and a lower after use to be disposed of material content.

Zum Ausbringen der Masse wird das Foliengebinde üblicherweise in eine Aufnahme einer Auspressvorrichtung, beispielsweise eines Dispensers, eingeschoben. Über einen Auspressmechanismus wird die ein- oder mehrkomponentige Masse durch eine Austrittsöffnung im Kopfteil ausgepresst und anschließend (zumindest im Fall einer mehrkomponentigen Masse) zur besseren Vermischung durch einen Mischeraufsatz mit einem Mischerelement hindurchgeführt.For dispensing the mass, the film container is usually in a receptacle of a squeezing device, such as a dispenser, inserted. About a Auspressmechanismus the one- or multi-component mass is squeezed out through an outlet opening in the head part and then passed (at least in the case of a multicomponent mass) for better mixing through a mixer attachment with a mixer element.

Aus der DE 10 2008 040 738 A1 ist ein Foliengebinde der eingangs genannten Art mit zwei seitlich nebeneinander angeordneten Folienbeuteln bekannt, das zwei- und mehrkomponentige Massen aufnehmen kann und zum Einschieben in eine Auspressvorrichtung mit zwei nebeneinander angeordneten Aufnahmen geeignet ist.From the DE 10 2008 040 738 A1 is a film container of the type mentioned above with two laterally juxtaposed foil bags known that can accommodate two- and multi-component masses and is suitable for insertion into a squeezing with two juxtaposed recordings.

Aus der WO 2012/136935 A1 und der WO 2015/164817 A1 ist jeweils ein Foliengebinde mit einem Folienbeutel sowie einem Kopfteil mit einem Befestigungsabschnitt für ein Ende des Folienbeutels bekannt. Der Folienbeutel hat jeweils die Form eines Kegelstumpfes, wobei der Durchmesser des Folienbeutels sich von dem Befestigungsabschnitt ausgehend in Richtung der Längsachse verringert.From the WO 2012/136935 A1 and the WO 2015/164817 A1 In each case, a foil container with a foil bag and a head part with a fastening portion for one end of the foil bag is known. The film bag has the shape of a truncated cone, wherein the diameter of the film bag decreases starting from the attachment portion in the direction of the longitudinal axis.

Weiterhin ist aus der EP2 045 196 A2 ein Foliengebinde mit zwei nebeneinander angeordnete Folienbeutelkammern für voneinander getrennt gelagerte Komponenten einer mehrkomponentigen Masse. Weiterhin ist ein eine Grundplatte aufweisende Kopfteil vorgesehen, wobei die Grundplatte mit einer Anlageseite ausgeführt ist, an der zwei Aufnahmeabschnitte für jeweils eines der Enden der Folienbeutelkammern vorgesehen sind. Zudem ist ein Mischeranschluss mit Austrittsöffnungen für die Komponenten der mehrkomponentigen Masse vorgesehen.Furthermore, from the EP2 045 196 A2 a film package with two juxtaposed foil bag chambers for separately stored components of a multi-component mass. Furthermore, a head plate having a base plate is provided, wherein the base plate is designed with a contact side, are provided on the two receiving portions for each one of the ends of the foil bag chambers. In addition, a mixer connection is provided with outlet openings for the components of the multicomponent mass.

Um ein problemloses axiales Einschieben des Foliengebindes in die Aufnahme zu ermöglichen, wird zwischen der Folienaußenwand und der Innenwand der Aufnahme ein Spalt benötigt. Bei der Entleerung des Foliengebindes, etwa mittels eines in der Aufnahme verschieblichen Kolbens, wird die Folie des bzw. der Folienbeutel gedehnt, wodurch es zur Anlage der Folie an die Innenwand der Aufnahme kommt. Dabei wird die Folie aufgeweitet, und die gegebenenfalls verschiedenen Folien der einzelnen Beutel erfahren unterschiedliche Spannungen, welche bei Druckentlastung zu einem ungleichmäßigen Nachdrücken der verschiedenen Komponenten führen. Dieses Ausdehnen und Zurückstellen der Folienbeutel wird auch als Pumpen bezeichnet und führt insbesondere beim Anlaufverhalten zu Fehlern im Mischungsverhältnis.In order to enable trouble-free axial insertion of the film pack into the receptacle, a gap is required between the film outer wall and the inner wall of the receptacle. When emptying the Foliengebindes, such as by means of a displaceable in the receptacle piston, the film of the film bag or is stretched, whereby it comes to rest the film to the inner wall of the recording. The film is widened, and if necessary Different films of the individual bags experience different voltages, which lead to uneven pressing of the various components when pressure is released. This expansion and resetting of the foil bag is also referred to as a pump and leads in particular to the startup behavior to errors in the mixing ratio.

Es ist daher Aufgabe der Erfindung, eine Baugruppe aus Foliengebinde und Auspressvorrichtung zur Verfügung zu stellen, bei dem bzw. der das unerwünschte Ausdehnen und Zurückstellen der Folien wirkungsvoll verhindert wird.It is therefore an object of the invention to provide an assembly of film container and squeezing available, in which or the undesirable expansion and resetting of the films is effectively prevented.

Gemäß einem ersten Aspekt der Erfindung ist dazu bei einer Baugruppe der eingangs genannten Art vorgesehen, dass der wenigstens eine Folienbeutel im gefüllten Zustand die Form eines Kegelstumpfs hat, dessen Durchmesser sich vom Befestigungsabschnitt ausgehend in Richtung seiner Längsachse verringert, und dass die wenigstens eine Aufnahme eine komplementär zum Folienbeutel ausgebildete, kegelstumpfförmige Innenumfangswand aufweist, wobei der wenigstens eine Folienbeutel im vollständig eingeschobenen Zustand flächig an der Innenumfangswand der Aufnahme anliegt.According to a first aspect of the invention is provided in an assembly of the type mentioned that the at least one foil bag in the filled state has the shape of a truncated cone, the diameter of which decreases starting from the attachment portion in the direction of its longitudinal axis, and that the at least one receptacle a Complementary to the foil bag formed, frusto-conical inner peripheral wall, wherein the at least one foil bag in the fully inserted state lies flat against the inner peripheral wall of the receptacle.

Bei der erfindungsgemäßen Ausgestaltung weisen also sowohl der wenigstens eine Folienbeutel als auch die dazugehörige Aufnahme leicht geneigte Umfangswände auf, was das Einschieben des Folienbeutels in die zugehörige Aufnahme auch ohne Vorsehen eines Fügespalts ermöglicht. Nach dem vollständigen Einschieben des Folienbeutels liegt die Folienaußenwand flächig an der Innenwand der Aufnahme an, wodurch ein Ausdehnen und Zurückstellen des Folienbeutels beim Entleeren zuverlässig verhindert wird. Die Innenumfangswand der Aufnahme bietet im vollständig eingeschobenen Zustand eine vollständige Unterstützung des Folienbeutels, sodass dieser auch unter Druck keine Ausdehnung erfahren kann und somit auch keine Rückstellung auftritt. Auf diese Weise wird das unerwünschte Pumpen vermieden. Außerdem ist, verglichen mit einem kreiszylindrisch ausgeführten Folienbeutel, aufgrund der Schrägen ein deutlich einfacheres Einschieben möglich.In the embodiment according to the invention, therefore, both the at least one foil pouch and the associated receptacle have slightly inclined peripheral walls, which makes it possible to insert the foil pouch into the associated receptacle even without providing a joining gap. After complete insertion of the film bag, the film outer wall is flat against the inner wall of the receptacle, whereby a stretching and returning the film bag when emptying is reliably prevented. The inner peripheral wall of the receptacle provides in the fully inserted state, a complete support of the foil bag, so that even under pressure can not experience expansion and thus no default occurs. In this way, the unwanted pumping is avoided. In addition, compared to a circular cylindrical running foil bag, a much easier insertion is possible due to the slopes.

Gemäß einer bevorzugten Ausführungsform liegt der Kegelwinkel bzw. Öffnungswinkel des Kegelstumpfs im Bereich von 0,1° bis 10°, insbesondere von 2° bis 6°. Der bzw. die Folienbeutel sowie die Aufnahme(n) sind somit nur mit einer leichten Anschrägung versehen, wodurch das Einführen erleichtert wird und auf einen Fügespalt verzichtet werden kann. Gleichzeitig ermöglicht eine nur geringfügige Neigung der Umfangswände ein zuverlässiges Auspressen der enthaltenen Masse(n) mit Hilfe (je) eines in der Aufnahme geführten Kolbens. Da sich der Durchmesser des Folienbeutels von dem Ende, an dem der Kolben angreift, bis zu dem am Befestigungsabschnitt des Folienbeutels festgelegten anderen Ende nur geringfügig vergrößert, wird auch bei Verwendung eines herkömmlichen Kolbens der Folienbeutel vollständig entleert.According to a preferred embodiment, the cone angle or opening angle of the truncated cone is in the range of 0.1 ° to 10 °, in particular from 2 ° to 6 °. The or the foil bag and the receptacle (s) are thus provided only with a slight chamfer, whereby the insertion is facilitated and can be dispensed with a joint gap. At the same time allows only a slight inclination of the peripheral walls reliable squeezing of the contained mass (s) with the help of (ever) a guided in the recording piston. Since the diameter of the film bag increases only slightly from the end at which the piston engages to the other end fixed to the attachment portion of the film bag, even when a conventional piston is used, the film bag is completely emptied.

Gemäß einer bevorzugten Ausführungsform weist das Foliengebinde einen ersten Folienbeutel und einen neben dem ersten Folienbeutel angeordneten zweiten Folienbeutel für getrennt voneinander gelagerte Komponenten einer mehrkomponentigen Masse auf, wobei beide Folienbeutel kegelstumpfförmig ausgebildet sind. Damit eignet sich das Foliengebinde zur Aufbewahrung einer zweikomponentigen Masse, die erst beim Auspressen miteinander vermischt wird. Natürlich ist es zur Lagerung von mehr als zwei Komponenten möglich, mehrere Beutel vorzusehen, oder alternativ einen oder mehrere Folienbeutel mit mehreren Kammern auszubilden, in denen mehrere unterschiedliche Komponenten getrennt voneinander gelagert werden können.According to a preferred embodiment, the film package has a first film bag and a second film bag arranged next to the first film bag for separately mounted components of a multi-component mass, wherein both film bags are frusto-conical. Thus, the film container is suitable for storing a two-component mass, which is mixed together only during pressing. Of course, it is possible for the storage of more than two components to provide multiple bags, or alternatively form one or more foil bags with multiple chambers in which several different components can be stored separately from each other.

Bevorzugt weist dann das Kopfteil einen ersten Befestigungsabschnitt für ein Ende des ersten Folienbeutels und einen seitlich daneben angeordneten zweiten Befestigungsabschnitt für ein Ende des zweiten Folienbeutels auf, insbesondere wobei von jedem Folienbeutel ein Durchtrittskanal im Kopfteil vorgesehen ist und die Durchtrittskanäle im Kopfteil in eine gemeinsame Austrittsöffnung münden. Auf die Austrittsöffnung wird üblicherweise ein Mischeraufsatz aufgeschraubt, was ein einfaches Vermischen der zwei oder mehr in den beiden Folienbeuteln gelagerten Komponenten unmittelbar beim Auspressen gewährleistet.Preferably, the head part then has a first fastening section for one end of the first film bag and a laterally arranged second attachment section for one end of the second film bag, in particular of each film bag, a passageway in the head part is provided and the passageways in the head part open into a common outlet opening , A mixer attachment is usually screwed onto the outlet opening, which ensures a simple mixing of the two or more components stored in the two foil bags immediately upon pressing.

Die Auspressvorrichtung hat dabei vorzugsweise eine erste Aufnahme für den ersten Folienbeutel und eine seitlich daneben angeordnete zweite Aufnahme für den zweiten Folienbeutel, wobei beide Aufnahmen in Richtung ihrer Längsachse konisch zulaufende Innenumfangswände haben. So ist für eine zuverlässige flächige Unterstützung der Außenwände beider Folienbeutel gesorgt.The squeezing device preferably has a first receptacle for the first foil bag and a laterally arranged second receptacle for the second foil bag, wherein both receptacles have tapered inner peripheral walls in the direction of their longitudinal axis. This ensures reliable surface support for the outer walls of both foil bags.

In einer bevorzugten Ausführungsform weisen die beiden Folienbeutel denselben Kegelwinkel und damit dieselbe Neigung gegenüber der Längsachse auf, was insbesondere in Bezug auf die zugeordneten Aufnahmen fertigungstechnisch günstiger ist.In a preferred embodiment, the two film bags on the same cone angle and thus the same inclination relative to the longitudinal axis, which is particularly favorable in terms of manufacturing technology with respect to the associated recordings.

Alternativ können die beiden kegelstumpfförmigen Folienbeutel verschiedene Kegelwinkel haben. Entscheidend ist, dass die jeweils zugeordnete Aufnahme einen auf den Kegelwinkel des Folienbeutels abgestimmten Kegelwinkel aufweist. Insbesondere sind die beiden Folienbeutel aus Folien mit unterschiedlichen mechanischen Eigenschaften gefertigt. Aufgrund der vollflächigen Unterstützung der Folienbeutel in der jeweiligen Aufnahme ist ja ein Aufdehnen und Rückstellen der Folienbeutel zuverlässig verhindert, sodass bei der erfindungsgemäßen Ausgestaltung keine Abstimmung der mechanischen Eigenschaften der verschiedenen Folienbeutel mehr vonnöten ist.Alternatively, the two frusto-conical film bags may have different cone angles. It is crucial that the respectively associated receptacle has a cone angle matched to the cone angle of the film bag. In particular, the two film bags are made of films with different mechanical properties. Due to the full-surface support of the foil bag in the respective recording yes, a stretching and resetting of the foil bag is reliably prevented, so that in the embodiment according to the invention no tuning of the mechanical properties of the various foil bag is more necessary.

In einer bevorzugten Ausgestaltung der Erfindung weist der erste Folienbeutel entlang seiner gesamten Länge einen größeren Durchmesser auf als der zweite Folienbeutel. Der erste Folienbeutel hat somit bei gleicher Länge ein größeres Fassungsvermögen, was ein vom Verhältnis 1:1 abweichendes Mischungsverhältnis der beiden Komponenten ermöglicht. Im Prinzip ist über den Durchmesser der Beutel ein beliebiges Mischungsverhältnis der Komponenten realisierbar.In a preferred embodiment of the invention, the first film bag has a larger diameter over its entire length than the second film bag. The first foil bag thus has a greater capacity for the same length, which allows a mixing ratio of the two components deviating from the ratio of 1: 1. In principle, over the diameter of the bag, any mixing ratio of the components can be realized.

Bei dem Foliengebinde, das als solches kein eigenständiger Bestandteil der Erfindung ist, kann der wenigstens eine Folienbeutel im gefüllten Zustand die Form eines Kegelstumpfs haben, dessen Durchmesser sich vom Befestigungsabschnitt ausgehend in Richtung seiner Längsachse verringert, wobei das Foliengebinde einen ersten Folienbeutel und einen neben dem ersten Folienbeutel angeordneten zweiten Folienbeutel für getrennt voneinander gelagerte Komponenten einer mehrkomponentigen Masse aufweist, wobei beide Folienbeutel kegelstumpfförmig ausgebildet sind. Ein solches Foliengebinde ermöglicht die Aufbewahrung und Bereitstellung von Mehrkomponentenmassen und lässt sich auch ohne Vorsehen eines Fügespalts problemlos in die Aufnahme einer Auspressvorrichtung einschieben. Weiterhin ermöglicht es, dass der Folienbeutel im vollständig eingeschobenen Zustand flächig an einer Innenumfangswand der Aufnahme anliegt, wodurch das unerwünschte Ausdehnen und Zurückstellen des Folienbeutels beim Auspressen der Masse aus dem Folienbeutel zuverlässig verhindert wird.In the film package, which as such is not an independent part of the invention, the at least one film bag in the filled state may have the shape of a truncated cone, the diameter of which decreases starting from the attachment portion in the direction of its longitudinal axis, wherein the film package a first film bag and one next to the first foil bag arranged second foil pouch for having separately mounted components of a multi-component mass, wherein both foil bags are frusto-conical. Such a film container allows the storage and provision of multi-component masses and can be easily inserted into the receptacle of a squeezing device even without providing a joining gap. Furthermore, it makes it possible that the film bag in the fully inserted state flat against an inner peripheral wall of the receptacle, whereby the unwanted expansion and return of the film bag when squeezing the mass from the film bag is reliably prevented.

Vorzugsweise hat das Kopfteil einen ersten Befestigungsabschnitt für ein Ende des ersten Folienbeutels und einen seitlich daneben angeordneten zweiten Befestigungsabschnitt für ein Ende des zweiten Folienbeutels, insbesondere wobei von jedem Folienbeutel ein Durchtrittskanal im Kopfteil vorgesehen ist und die Durchtrittskanäle im Kopfteil in eine gemeinsame Austrittsöffnung münden. Dadurch wird eine platzsparende Aufbewahrung und einfache Vermischung einer zweikomponentigen Masse erzielt.Preferably, the head part has a first attachment portion for one end of the first foil bag and a laterally arranged second securement portion for one end of the second foil pouch, in particular of each foil pouch a passageway in the head part is provided and the passageways in the head part open into a common outlet opening. This results in a space-saving storage and easy mixing of a two-component mass is achieved.

Darüber hinaus gelten sämtliche mit Bezug auf die erfindungsgemäße Baugruppe genannten Weiterbildungen und Vorteile auch für das erfindungsgemäße Foliengebinde und umgekehrt.In addition, all mentioned with respect to the assembly according to the invention further developments and advantages also apply to the film package according to the invention and vice versa.

Weitere Merkmale und Vorteile ergeben sich aus der nachfolgenden Beschreibung einer bevorzugten Ausführungsform anhand der beigefügten Zeichnungen. In diesen zeigt:

Die Figuren 1 bis 3 zeigen eine erfindungsgemäße Baugruppe 10, die ein Foliengebinde 12 zur Aufbewahrung einer hier zweikomponentigen Masse und eine Auspressvorrichtung 14 für das Foliengebinde 12 aufweist.The FIGS. 1 to 3 show an assembly 10 according to the invention, which has a film container 12 for storing a two-component mass here and a squeezing device 14 for the film package 12.

Das Foliengebinde 12 umfasst einen ersten, gefüllten Folienbeutel 16 sowie einen seitlich neben dem ersten Folienbeutel 16 angeordneten zweiten, gefüllten Folienbeutel 18, die zur Aufbewahrung der beiden getrennt voneinander gelagerten Komponenten der zweikomponentigen Masse dienen. Die Folienbeutel 16, 18 selbst sind länglich und (ohne Inhalt) nicht eigensteif ausgebildet.The film package 12 comprises a first, filled film bag 16 and a laterally next to the first film bag 16 arranged second, filled film bag 18, which serve to store the two separately stored components of the two-component mass. The foil bags 16, 18 themselves are elongated and (without content) not intrinsically stiff.

Ferner weist das Foliengebinde 12 ein eigensteifes Kopfteil 20 auf, das einen ersten Befestigungsabschnitt 22 hat, an dem ein Ende 24 des ersten Folienbeutels 16 festgelegt ist. Seitlich neben dem ersten Befestigungsabschnitt 22 ist ein zweiter Befestigungsabschnitt 26 für ein Ende 28 des zweiten Folienbeutels 18 vorgesehen. Beide Folienbeutel 16, 18 sind am Kopfteil 20 unlösbar festgelegt. Darüber hinaus sind im Kopfteil 20 zwei Durchtrittskanäle 30, 32 ausgebildet, die je einen der Folienbeutel 16, 18 mit einer gemeinsamen Austrittsöffnung 34 verbinden. Auf diese wird üblicherweise ein Mischeraufsatz (nicht gezeigt) aufgeschraubt.Furthermore, the film package 12 has an intrinsically stiff head part 20, which has a first fastening section 22 on which an end 24 of the first film bag 16 is fixed. Laterally adjacent to the first attachment portion 22, a second attachment portion 26 is provided for an end 28 of the second foil bag 18. Both foil bags 16, 18 are fixed permanently on the head part 20. In addition, two passageways 30, 32 are formed in the head part 20, each connecting one of the film bags 16, 18 with a common outlet opening 34. On this usually a mixer attachment (not shown) is screwed.

Beide Folienbeutel 16, 18 haben die Form eines Kegelstumpfs, dessen Durchmesser sich vom jeweiligen Befestigungsabschnitt 22 bzw. 26 ausgehend in Richtung einer Längsachse L der Folienbeutel 16, 18 verringert. Dabei liegen sowohl der Kegelwinkel α1 des ersten Folienbeutels 16 wie auch der Kegelwinkel α2 des zweiten Folienbeutels 18 im Bereich von 0,1° bis 10°, insbesondere von 2° bis 6°. Bei der gezeigten Ausführungsform betragen beide Kegelwinkel α1 und α2 etwa 4°, wie aus Figur 1 ersichtlich ist, in der aus Platzgründen anstelle der eigentlichen Kegelwinkel α1 und α2 die Neigungswinkel α1/2 und α2/2 eingezeichnet sind, die ja gerade jeweils dem halben Kegelwinkel entsprechen.Both film bags 16, 18 have the shape of a truncated cone, the diameter of which decreases from the respective attachment portion 22 and 26, respectively, in the direction of a longitudinal axis L of the film bag 16, 18. Both the cone angle α 1 of the first film bag 16 and the cone angle α 2 of the second film bag 18 are in the range of 0.1 ° to 10 °, in particular from 2 ° to 6 °. In the embodiment shown, both cone angles α 1 and α 2 are approximately 4 °, as shown FIG. 1 be seen, the inclination angle α 1/2 and α 2/2 are shown in the lack of space instead of the actual cone angle α 1 and α 2, the yes respectively correspond exactly to the half cone angle.

Der erste Folienbeutel 16 weist entlang seiner gesamten Länge einen größeren Durchmesser als der zweite Folienbeutel 18 auf, wie den Figuren zu entnehmen ist. Folglich enthält der erste Folienbeutel 16 ein größeres Volumen der zweikomponentigen Masse, wodurch diese Komponente bei der fertig gemischten Masse überwiegt. Grundsätzlich ist über das Volumen- bzw. Durchmesserverhältnis der Folienbeutel 16, 18 das Mischungsverhältnis der zweikomponentigen Masse einstellbar.The first film bag 16 has along its entire length a larger diameter than the second film bag 18, as can be seen from the figures. Consequently, the first foil bag 16 contains a larger volume of the two-component mass, whereby this component predominates in the ready-mixed mass. In principle, the mixing ratio of the two-component mass can be adjusted via the volume or diameter ratio of the film bags 16, 18.

Die Auspressvorrichtung 14, die in den Figuren nur teilweise gezeigt ist (auf die Darstellung des eigentlichen Auspressmechanismus, etwa in Form eines oder mehrerer Kolben, wurde verzichtet), weist eine erste Aufnahme 36 für den ersten Folienbeutel 16 sowie eine seitlich daneben angeordnete zweite Aufnahme 38 für den zweiten Folienbeutel 18 auf. Beide Aufnahmen 36, 38 haben eine komplementär zum zugeordneten Folienbeutel 16, 18 ausgebildete, kegelstumpfförmige Innenumfangswand 40 bzw. 42, die in Richtung der Längsachse L jeweils konisch zulaufen. Dabei entsprechen die Kegelwinkel α1, α2 der Innenumfangswände 40, 42 dem des jeweils zugeordneten Folienbeutels 16, 18.The squeezing device 14, which is only partially shown in the figures (the representation of the actual squeezing mechanism, in the form of one or more pistons, has been omitted), has a first receptacle 36 for the first foil bag 16 and a second receptacle 38 arranged laterally next to it for the second foil bag 18. Both receptacles 36, 38 have a complementary to the associated foil bag 16, 18 formed, frusto-conical inner peripheral wall 40 and 42, respectively tapered in the direction of the longitudinal axis L. In this case, the cone angles α 1 , α 2 of the inner peripheral walls 40, 42 correspond to those of the respectively associated foil bag 16, 18.

Figur 2 zeigt eine Mittelstellung, in der das Foliengebinde 12 etwa zur Hälfte in die Auspressvorrichtung 14 eingeschoben ist. Aufgrund der kegelstumpfförmigen Ausbildung sowohl der Folienbeutel 16, 18 als auch der Aufnahmen 36, 38 ist das Vorsehen eines Fügespalts, wie er von herkömmlichen kreiszylindrischen Folienbeuteln bekannt ist, hier nicht nötig. Durch die Neigung der beteiligten Wände ist zudem ein einfacheres Einschieben möglich. FIG. 2 shows a middle position in which the film container 12 is inserted about halfway into the squeezing device 14. Due to the frusto-conical design of both the foil bag 16, 18 and the receptacles 36, 38, the provision of a joint gap, as is known from conventional circular cylindrical foil bags, not necessary here. Due to the inclination of the walls involved a simpler insertion is also possible.

Figur 3 schließlich illustriert die Endstellung, in der beide Folienbeutel 16, 18 vollständig in die jeweils zugehörige Aufnahme 36, 38 eingeschoben sind. In diesem vollständig eingeschobenen Zustand liegen beide Folienbeutel 16, 18 flächig an der jeweiligen Innenumfangswand 40 bzw. 42 der zugeordneten Aufnahme 36, 38 an. FIG. 3 Finally, illustrates the end position in which both foil bags 16, 18 are completely inserted into the respectively associated receptacle 36, 38. In this fully inserted state, both film bags 16, 18 lie flat against the respective inner peripheral wall 40 or 42 of the associated receptacle 36, 38.

Aufgrund dieser vollständigen Unterstützung bzw. vollflächigen Anlage in der Endstellung ist bei der erfindungsgemäßen Ausgestaltung keine Abstimmung der mechanischen Eigenschaften notwendig, weshalb die beiden Folienbeutel 16, 18 aus Folien mit unterschiedlichen mechanischen Eigenschaften gefertigt sein können.Due to this complete support or full surface contact in the end position is in the embodiment of the invention no vote of mechanical properties necessary, which is why the two film bags 16, 18 can be made of films with different mechanical properties.
