Vorzugsweise bestehen der zylindrische Körper und die Deckelteile aus Verbundfolien, die Metallschichten enthalten. Die Erfindung betrifft auch ein Verfahren zur Herstellung einer befüllten Verpackung für Innendruck erzeugende Füllgüter sowie die Verwendung der Verpackung insbesondere für Flüssigkeiten.The present invention relates to a flexible, stable packaging, which consists of a cylindrical body made of a film, each having a cover part welded to it at the upper and lower ends. The cylindrical body and the cover parts preferably consist of composite films which contain metal layers. The invention also relates to a method for producing a filled packaging for products producing internal pressure and the use of the packaging, in particular for liquids.
Description
Die vorliegende Erfindung betrifft eine druckbelastbare flexible Verpackung für unter Innendruck stehende Füllgüter, insbesondere Flüssigkeiten, ein Verfahren zur Herstellung einer befüllten Verpackung sowie die Verwendung der Verpackung.The present invention relates to a pressure-resistant flexible packaging for filling goods under internal pressure, in particular liquids, a method for producing a filled packaging and the use of the packaging.
Füllgüter, insbesondere Druckgase enthaltende Flüssigkeiten, wie z.B. kohlensäurehaltiges Mineralwasser oder Fruchtsaftgetränke, werden bisher lediglich in Metalldosen oder in Flaschen abgefüllt. Das Problem dieser Verpackungen besteht darin, daß sie sehr voluminös sind und daher die Umwelt bei der Beseitigung entsprechend belasten.Filling goods, in particular liquids containing compressed gases, such as e.g. Carbonated mineral water or fruit juice drinks have so far only been filled in metal cans or in bottles. The problem with this packaging is that it is very bulky and therefore pollutes the environment accordingly when it is disposed of.
Flexible Verpackungen für sogenannte "stille" Flüssigkeiten, d.h. solche, die nicht unter Druck stehen, sind z.B. aus den DE-PSen 12 81 140 bzw. 13 03 917 bekannt. Diese flexiblen Verpackungen haben gegenüber den obengenannten Dosen oder Flaschen den erheblichen Vorteil, daß sie nach der Entnahme der Flüssigkeit leicht zusammenfaltbar sind und sich daher umweltfreundlich vernichten lassen.Flexible packaging for so-called "still" liquids, ie those that are not under pressure, are known, for example, from D E -PSen 12 81 140 or 13 03 917. Compared to the cans or bottles mentioned above, these flexible packages have the considerable advantage that they can be easily folded up after the liquid has been removed and can therefore be destroyed in an environmentally friendly manner.
Ein Nachteil bei diesen versiegelten flexiblen Verpackungen besteht jedoch darin, daß sie bei Befüllung mit unter Gasdruck stehenden Flüssigkeiten infolge Spaltung der Nähte aufreißen, so daß die Flüssigkeiten auslaufen.A disadvantage of this sealed flexible packaging, however, is that when it is filled with liquids under gas pressure, they tear open due to splitting of the seams, so that the liquids leak.
Es stellte sich somit die Aufgabe, eine flexible, standfähise Verpackung zu entwickeln, die alle für den Schutz des Füllgutes notwendigen Schichten aufweist, bei der der vom Füllgut, vorzugsweise von den Flüssigkeiten, ausgehende Innendruck nicht zum Aufreißen infolge Spaltung der Siegelnähte führt und die sich nach der Entnahme des Füllgutes zu einer - bezogen auf das ursprüngliche Volumen - stark verminderten Größe von Hand leicht zusammendrücken läßt.It was therefore the task to develop a flexible, stable packaging that has all the layers necessary for the protection of the filling material, in which the internal pressure emanating from the filling material, preferably from the liquids, does not lead to tearing due to the splitting of the sealing seams and which after removal of the filling material to a - in relation to the original volume - greatly reduced size can be compressed by hand.
Gelöst wird die vorstehend genannte Aufgabe durch die in Anspruch 1 angegebenen Merkmale.The above object is achieved by the features specified in claim 1.
Der zylindrische flexible Körper kann wahlweise aus einer siegelfähigen nahtlosen Schlauchfolie oder mit einer versiegelten Uberlappungsnaht gebildet sein. Der letztere Fall ist auf jeden Fall dann gegeben, wenn der zylindrische Körper aus einer Verbundfolie besteht, die eine oder mehrere Metallschichten, vorzugsweise in Form von Aluminiumfolien, enthält. Ansonsten kann der zylindrische Körper aus einer siegelfähigen Monofolie oder aus einer Verbundfolie bestehen, wobei letztere u.a. durch Coextrusion in Flach- oder Schlauchform hergestellt werden kann.The cylindrical flexible body can optionally be formed from a sealable seamless tubular film or with a sealed overlap seam. The latter case is given in any case if the cylindrical body consists of a composite foil which contains one or more metal layers, preferably in the form of aluminum foils. Otherwise, the cylindrical body can consist of a sealable monofilm or a composite film, the latter including can be produced by coextrusion in flat or tubular form.
Bei der Herstellung von Metallschichten enthaltenden Verbunden besteht der zylindrische Körper aus Folien, die durch Schmelzbeschichtung oder durch Kaschierung hergestellt sind.In the production of composites containing metal layers, the cylindrical body consists of foils which are produced by melt coating or by lamination.
Die aufgebrachten Siegelschichten sind allgemein bekannt und bestehen vorzugsweise aus Polyethylen, Copolymeren mit Polvethylen oder aus Ethylen-Vinylacetat-Copolymeren.The applied sealing layers are generally known and preferably consist of polyethylene, copolymers with polyethylene or from ethylene-vinyl acetate copolymers.
Welche Folien - ob Mono- oder Verbundfolien - für den zylindrischen Körper eingesetzt werden, hängt von dem jeweiligen Füllgut ab. Die einsetzbaren Folien gehören zum allgemeinen Stand der Technik und brauchen deshalb nicht näher erläutert zu werden.Which foils - whether mono or composite foils - are used for the cylindrical body depends on the respective filling material. The films that can be used belong to the general state of the art and therefore do not need to be explained in more detail.
Je nach Gasdurchlässigkeit der Folien hat es sich als zweckmäßig erwiesen, Gassperrschichten einzubauen. Ist das Füllgut lichtempfindlich, d.h. daß es sich unter Einfluß von-Licht verfärbt oder gar zersetzt, werden vorzugsweise Verbundfolien eingesetzt, die Metallschichten enthalten. Bei solchen Verbundfolien ist weiterhin eine gute Gasundurchlässigkeit gewährleistet. Wie oben erwähnt, ist in diesem Fall der zylindrische Körper mit einer Uberlappungsnaht ausgestattet.Depending on the gas permeability of the foils, it has proven expedient to install gas barrier layers. The filling material is light-sensitive, ie, that it is under the influence of - discolored or decomposed even light, preferably composite films are used which contain metal layers. With such composite films, good gas impermeability is still guaranteed. In this case, as mentioned above, the cylindrical body is provided with an overlap seam.
Der zylindrische Körper enthält an den Kopfenden verschweißte Deckelteile, die aus Spritzgußteilen und/oder flexiblen Folien bestehen.The cylindrical body contains welded cover parts at the head ends, which consist of injection molded parts and / or flexible foils.
Hierbei kann ein Deckelteil aus einem Spritzgußteil und das andere Deckelteil aus einer Folie bestehen. Bevorzugt ist jedoch, daß beide Deckelteile aus Folien bestehen, da sich dabei die Verpackung nach der Entnahme des Füllgutes besonders leicht von Hand zusammendrücken läßt. Falls es aufgrund des Füllgutes zweckmäßig erscheint, daß der zylindrische Körper aus einem Verbund aufgebaut ist, so sind zweckmäßig auch die Deckelteile aus vorzugsweise den gleichen Verbunden ausgebildet.Here, a cover part can consist of an injection molded part and the other cover part can consist of a film. However, it is preferred that both cover parts consist of foils, since the packaging can be pressed together particularly easily by hand after the contents have been removed. If it appears expedient because of the filling material that the cylindrical body is constructed from a composite, then the cover parts are also expediently made of preferably the trained in the same network.
Wenn der zylindrische Körper eine oder mehrere Metallschichten enthält, so ist es bevorzugt, daß auch die Deckelschichten entsprechend eine oder mehrere Metallschichten aufweisen. Bei einer Ausführungsform kann z.B. eines der Deckelteile den Rand des zylindrischen Körpers umgreifend von außen auf diesen aufgesiegelt sein. Diese Ausführungsform ist bei der Verwendung von Folien als Deckelteil deswegen bevorzugt, da hier bei der Versiegelung von innerhalb des zylindrischen Rohres ein Stützdruck ausgeübt werden kann.If the cylindrical body contains one or more metal layers, it is preferred that the cover layers accordingly also have one or more metal layers. In one embodiment, e.g. one of the cover parts around the edge of the cylindrical body to be sealed onto it from the outside. This embodiment is preferred when using foils as a cover part because a support pressure can be exerted during the sealing from within the cylindrical tube.
Besonders bevorzugt ist eine Ausführungsform, bei der das den Kopfteil der Verpackung bildende Deckelteil den Rand des zylindrischen Körpers umgreifend von außen auf diesen aufgesiegelt ist und das den Boden bildende Deckelteil von innen in den zylindrischen Körper eingesiegelt ist. Hierbei werden vorzugsweise Folien verwendet, die nur auf einer Seite eine Siegelschicht aufweisen, die aber dann bei der Herstellung der befüllten Verpackung zur Form einer Wanne umgestülpt werden müssen.An embodiment is particularly preferred in which the cover part forming the head part of the packaging is sealed around the edge of the cylindrical body from the outside, and the cover part forming the bottom is sealed into the cylindrical body from the inside. In this case, foils are preferably used which have a sealing layer on only one side, but which then have to be turned over into the shape of a tub during the production of the filled packaging.
Bei der Variante nach Figur 3, bei der die Umstülpung des Wannenrandes entfällt und wobei die Siegelnaht auf Spaltung beansprucht würde, ist es notwendig, daß wenigstens ein Stützring vorhanden ist, wodurch die Siegelnahtbelastung aufgenommen wird.In the variant according to FIG. 3, in which there is no turning over of the tub rim and the sealing seam would be subject to splitting, it is necessary that at least one support ring is present, as a result of which the sealing seam loading is absorbed.
Vorzugsweise ist bei Verwendung einer Folie als Deckelteil für die Bodenpartie diese derart eingesiegelt, daß der zylindrische Körper einen überstehenden Rand aufweist, da hierdurch die Standfestigkeit der Verpackung erhöht wird. Der beschriebene Stützring bzw. die Stützringe bestehen vorzugsweise aus siegelfähigen Polyvinylchloridstreifen, die wiederum bevorzugt eingerollt sind.Is preferred when using a film as a lid part for the bottom part sealed in such a way that the cylindrical body has a protruding edge, as this increases the stability of the packaging. The support ring or support rings described preferably consist of sealable polyvinyl chloride strips, which in turn are preferably rolled up.
Bei der Verpackung ist weiterhin vorgesehen, daß wenigstens ein Deckelteil und/oder die Wand des zylindrischen Körpers eine Schwächungsstelle aufweist, die durch Druck und/oder Einstechen leicht geöffnet werden kann und aus der nach der öffnung das Füllgut entnommen werden kann. Es ist auch möglich, sogenannte Aufreißlaschen'anzubringen.In the packaging it is further provided that at least one cover part and / or the wall of the cylindrical body has a weakening point which can be easily opened by pressure and / or piercing and from which the contents can be removed after opening. It is also possible to attach so-called pull tabs.
Die Erfindung betrifft auch ein Verfahren zur Herstellung einer befüllten Verpackung.The invention also relates to a method for producing a filled package.
Das Verfahren ist dadurch gekennzeichnet, daß man zuerst einen zylindrischen Körper aus einer flexiblen Folie formt, anschließend ein Deckelteil mit dem zylindrischen Körper mit Außen- und/oder Innennaht verschweißt, anschließend das Füllgut einfüllt und anschließend das zweite Deckelteil mit Außen- und/oder Innennaht anschweißt.The method is characterized in that first a cylindrical body is formed from a flexible film, then a cover part is welded to the cylindrical body with an outer and / or inner seam, then the filling is filled in and then the second cover part with an outer and / or inner seam welded on.
Falls vorzugsweise Metallschichten enthaltende Verbunde zur Verwendung kommen sollen, ist das Verfahren dadurch gekennzeichnet, daß man den zylindrischen Körper aus einer beidseitig siegelnden Flachfolie erzeugt, indem man zunächst eine Uberlappungsnaht herstellt und anschließend den zylindrischen Körper ausformt, wobei auch die umgekehrte Reihenfolge der Verfahrensschritte möglich ist.If it is preferred to use composites containing metal layers, the method is characterized in that the cylindrical body is made of egg ner produced on both sides sealing flat film by first producing an overlap seam and then shaping the cylindrical body, wherein the reverse order of the process steps is also possible.
Bei Verwendung von Folien wird bei Innenversiegelung so verfahren, daß man wenigstens eines der Deckelteile in gefalteten Zustand einführt und anschließend einsiegelt.When using foils, the procedure for internal sealing is such that at least one of the lid parts is inserted in the folded state and then sealed.
Bevorzugt ist ein Verfahren, das dadurch gekennzeichnet ist, daß man vor dem Versiegeln wenigstens eines der Deckelteile von der Innenseite aus wenigstens einen Stützring einführt.A method is preferred which is characterized in that before sealing at least one of the cover parts, at least one support ring is inserted from the inside.
Die Verpackung eignet sich grundsätzlich für alle Gasdruck abgebenden Füllgüter. Sie hat sich jedoch besonders für unter Gasdruck stehende Flüssigkeiten, vorzugsweise solche die Kohlensäure enthalten, bewährt. Hierzu zählen beispielsweise Mineralwässer, Bier, bestimmte Wein- und Sektarten und insbesondere Fruchtsaftgetränke.The packaging is basically suitable for all gas pressure-releasing goods. However, it has proven particularly useful for liquids under gas pressure, preferably those containing carbonic acid. These include, for example, mineral water, beer, certain types of wine and sparkling wine and, in particular, fruit juice drinks.
