Description

Die Erfindung betrifft eine Verbundpackung, insbesondere eine Getränkekartonverpackung für flüssige Lebensmittel, die wenigstens teilweise aus einem Packungslaminat besteht, mit einem Packungsgrundkörper, einem Packungsboden und einem Packungsgiebel, wobei der Packungsgiebel aus wenigstens einem Packungsgiebelpanel besteht, wobei das Packungsgiebelpanel durch eine wenigstens teilweise gekrümmte Vorderkante begrenzt ist.The invention relates to a composite package, in particular a beverage container packaging for liquid food, which consists at least partially of a packing laminate, with a packing body, a package bottom and a packing gable, wherein the packing gable consists of at least one packing gable panel, wherein the packing gable panel bounded by an at least partially curved leading edge is.

Die Erfindung betrifft zudem ein Packungslaminat mit wenigstens einer Kartonträgerschicht und einer Polymerschicht, mit einer Mehrzahl von in das Material eingearbeiteten Rillungen, um Packungsfalzlinien zur Ausbildung von Packungskanten vorzudefinieren.The invention further relates to a package laminate having at least one paperboard carrier layer and a polymer layer having a plurality of grooves formed in the material to predefine packet fold lines to form package edges.

Die Erfindung betrifft schließlich einen Packungsmantelrohling bestehend aus einem Packungslaminat mit wenigstens einer Kartonträgerschicht und einer Polymerschicht, mit einer Mehrzahl von in das Material eingearbeiteten Rillungen, um Packungsfalzlinien zur Ausbildung von Packungskanten vorzudefinieren, wobei das Packungslaminat auf das Intervall einer Verbundpackung zugeschnitten und durch eine Längssiegelnaht zu einem Rohr verbunden ist.Finally, the invention relates to a packing jacket blank comprising a packing laminate having at least one paperboard carrier layer and a polymer layer having a plurality of grooves formed in the material to predefine packing fold lines to form packing edges, the package laminate being cut to the interval of a composite package and fed through a longitudinal sealing seam connected to a pipe.

Im Bereich der Verpackungstechnik gehören Verbundverpackungen seit langem zum gängigen Stand der Technik. So bestehen beispielsweise Getränkekartons aus verschiedenen Packstoffen wie Papier und Kunststoffen, die, vollflächig gefügt und bedruckt, ein Packungslaminat bilden. Der Schichtaufbau kann je nach Anforderungen variieren, so wird beispielsweise für aseptische Füllgüter zusätzlich eine Aluminiumschicht eingelegt, um eine gute Barrierewirkung gegen Gase und Licht zu erzielen.In the field of packaging technology, composite packaging has long been part of the state of the art. For example, beverage cartons consist of various packaging materials, such as paper and plastics, which form a package laminate over the entire surface and printed. The layer structure can vary depending on the requirements, for example, for aseptic filling materials additionally an aluminum layer is inserted in order to achieve a good barrier effect against gases and light.

Das eigentliche Formen und Befüllen der Verpackung und das Verschließen zu einer Packung geschieht in einer Verpackungsmaschine, die nicht selten in Anlehnung an ihre Hauptfunktionen auch als Form-/Fill-/Seal-Maschine bezeichnet wird. Dabei haben sich das Schlauch- und das Mantelverfahren etabliert. Während beim ersten das Packungslaminat als Endlosmaterial (Rollenware) der Maschine zugeführt wird, ist bei letzterem das Packungslaminat bereits auf das Intervall einer Verpackung zugeschnitten. Nicht selten sind solche Zuschnitte zudem bereits zu einem Rohr umgelegt und durch eine Längssiegelnaht zu sogenannten Packungsmantelrohlingen verbunden, die dann als Halbzeug einer entsprechenden Maschine zur Verarbeitung bereitstehen. Als Füllgüter kommen vorwiegend flüssige Lebensmittel wie beispielsweise Getränke, Suppen oder Joghurt in Frage. Denkbar sind auch gestockte, pastöse oder stückige Produkte oder dergleichen.The actual forming and filling of the packaging and sealing to a pack is done in a packaging machine, which is often based on its main functions are also referred to as a form / fill / seal machine. In the process, the hose and jacket processes have become established. While the first, the package laminate is supplied as endless material (roll goods) of the machine, in the latter the package laminate is already cut to the interval of a package. Not infrequently, such blanks are also already turned into a tube and connected by a longitudinal sealing seam to so-called packing jacket blanks, which are then available as a semifinished product of a corresponding machine for processing. As fillings are mainly liquid foods such as drinks, soups or yogurt in question. Also conceivable are stacked, pasty or lumpy products or the like.

Die Verpackung wird durch umformende, fügende und zuweilen auch trennende Prozesse des Packungslaminats oder Packungsmantelrohlings geschaffen. Hierzu wird das Material u. a. gefalzt (maschinell gefaltet), so dass sich beispielsweise Packungsboden und Packungsgiebel bilden lassen und am Packungsgrundkörper Packungskanten entstehen. Um dem Material die nötige Biegefähigkeit zu verleihen, werden bei dessen Herstellung entsprechende Rillungen eingearbeitet. Ein solches Rillen bei der Herstellung des Packungslaminats ist beispielsweise in der auf den Anmelder zurückgehenden Offenlegungsschrift DE 10326106 A1 gezeigt. Das Ausführungsbeispiel zeigt einen gerillten, für das Mantelverfahren geeigneten Packungsmantelrohling. Vom Verbrauchermarkt zunehmend nachgefragte Packhilfsmittel, wie beispielsweise wiederverschließbare Verschlüsse, Öffnungs- und Ausgießvorrichtungen, Strohhalme, Pull Tabs, usw. erfordern oft eine zusätzliche Vorbehandlung des Packungslaminats, etwa in Form von lokal eingebrachten Schwächungen wie überbeschichteten Löchern oder speziellen Perforierungen oder dergleichen.The packaging is created by reshaping, mating, and sometimes separating processes of the package laminate or packing jacket blank. For this purpose, the material is, inter alia, folded (folded by machine), so that, for example, packing bottom and packing gable can be formed and packing edges are formed on the main body of the packing. In order to give the material the necessary bending ability, corresponding grooves are incorporated during its production. Such a groove in the manufacture of the package laminate is, for example, in the published patent application DE 10326106 A1 shown. The exemplary embodiment shows a grooved packing jacket blank suitable for the jacket method. Consumer packaging increasingly in demand packaging aids, such as resealable closures, opening and pouring devices, straws, pull tabs, etc. often require additional pretreatment of the package laminate, such as locally introduced weakenings such as overcoated holes or special perforations or the like.

Mittlerweile sind verschiedenste Packungsformen bekannt und verfügbar. So existieren Packungskörper mit speziell ausgebildeten Kanten, zusätzlichen Panelen, Rundungen und gewölbten Flächen. Den Kopfbereich der Packung schließen beispielsweise Flachgiebel oder Schräggiebel (etwa als Sattel- oder Pultdach) oder noch speziellere Geometrien ab. Zudem sind separat geschaffene Formteile für den Kopfbereich und Boden der Packung denkbar.Meanwhile, a variety of packaging forms are known and available. Thus, packing bodies with specially designed edges, additional panels, curves and curved surfaces exist. The head area of the package includes, for example, gable or bevel gable (such as a saddle or pent roof) or even more specific geometries. In addition, separately created moldings for the head and bottom of the pack are conceivable.

Die europäischen Patentanmeldung EP 1 332 969 A1 zeigt zum Beispiel eine im Schlauchverfahren geschaffene Schräggiebelpackung mit Pultdach. In das hierfür geeignete Packungslaminat sind entsprechende Rillmuster für die spätere Falzung eingearbeitet. Zudem ist für das eine Ausführungsbeispiel eine Schwächung im Bereich der Sollöffnung und des Ausgießers eingebracht.The European patent application EP 1 332 969 A1 shows, for example, a tubular gable with gable roof created by the tube method. Corresponding groove patterns for the subsequent folding are incorporated into the packaging laminate suitable for this purpose. In addition, a weakening in the region of the desired opening and the spout is introduced for the one embodiment.

Das auf den Anmelder zurückgehende europäische Patent EP 1 216 192 B1 zeigt eine relativ eckige - hier im Mantelverfahren geschaffene - Packung mit einem auf einem schrägen Giebelpanel angebrachten Ausgießelement. Das Schrägstellen des Panels vergrößert die Fläche für ein zu applizierendes Ausgießelement, respektive eröffnet die Möglichkeit dessen Durchmesser großzügiger zu dimensionieren. Dies ist regelmäßig gewünscht, da so sein Ausgießverhalten merklich verbessert wird.The European patent originating from the applicant EP 1 216 192 B1 shows a relatively square - created here in the shell process - packing with a mounted on a sloping gable panel pouring. The tilting of the panel increases the area for a pouring element to be applied, respectively, opens up the possibility of generously dimensioning its diameter. This is regularly desired because it significantly improves its pouring behavior.

Eine zusätzliche Vergrößerung des Giebelpanels kann durch eine gekrümmte Packungsvorderkante (einer sogenannten "smiling curve") erreicht werden, wie dies u.a. auch in der Nichtpatentliteratur XP-00824919 beschrieben steht.An additional enlargement of the gable panel can be achieved by a curved leading edge (a so-called "smiling curve"), as can i.a. also described in nonpatent literature XP-00824919.

Verschiedene Packungen machen sich eine solche gekrümmte Packungsvorderkante bereits zunutze, so beispielsweise auch einige, beispielhaft in der internationalen Publikation WO 2004076302 A1 gezeigte Formen.Various packs already make use of such a curved leading edge of packaging, for example some, by way of example in the international publication WO 2004076302 A1 shown shapes.

Vergrößerte Panele können aber auch für Packungen ohne Ausgießelement wünschenswert sein. So lässt oft bereits die Form des vergrößerten Giebels die Packung attraktiver und ansprechender erscheinen. Der vergrößerte Giebel hält zudem mehr Display-Fläche für ein gedrucktes Dekor bereit. Ferner lässt eine geschwungene Packungsvorderkante den Konsumenten leichter direkt von der Packung trinken ("on the go"), da die geschwungene Kante besser der Ergonomie des menschlichen Mundes entspricht.Enlarged panels can also be desirable for packages without pouring element. For example, the shape of the enlarged gable often makes the package look more attractive and appealing. The enlarged gable also provides more display space for a printed décor. Furthermore, a curved leading edge makes it easier for consumers to drink directly from the pack ("on the go"), as the curved edge better suits the ergonomics of the human mouth.

So geschaffene Panele bilden aber keine ebenen Flächen sondern eine nach Maßgabe von Falzung und Zwangsformung nach innen oder außen gewölbte Fläche. Solche sind aber ästhetisch oft unerwünscht und als Funktionsflächen nachteilig. Sollen Ausgießelemente angebracht werden, bedürfen diese einer möglichst ebenen Fläche, insbesondere auch dann, wenn sie vermittels Schmelzklebstoffen verbunden werden. Aber auch bei anderen Verbindungstechniken wie Heißluft oder Ultraschall ist eine ebene Fläche stets wünschenswert.Panels created in this way, however, do not form flat surfaces but rather a curved surface inward or outward in accordance with folding and compulsory molding. However, such are often undesirable aesthetically and as functional surfaces disadvantageous. If pouring elements are to be attached, they require as flat a surface as possible, in particular even if they are connected by means of hotmelt adhesives. But even with other joining techniques such as hot air or ultrasound a flat surface is always desirable.

Nicht selten lassen sich außerdem Rückstelleffekte oder Festigkeitseinbußen bei solchen Falzungen beobachten, die die Formintegrität der Packungen beeinträchtigen und diese allzu oft unansehnlich aussehen lassen.Not infrequently, reset effects or loss of strength can be observed in such folds, which affect the form integrity of the packs and all too often make them look unsightly.

Es ist deshalb Aufgabe der vorliegenden Erfindung, eine Verbundpackung, ein Packungslaminat und einen Packungsmantelrohling der eingangs genannten und zuvor näher beschriebenen Art so auszugestalten und weiterzubilden, dass die beschriebenen Nachteile überwunden werden. Insbesondere sollen Qualität und Funktionsfähigkeit verbessert werden.It is therefore an object of the present invention, a composite package, a packaging laminate and a packing jacket blank of the aforementioned and described in more detail above in such a way and further that the disadvantages described are overcome. In particular, quality and functionality should be improved.

Gelöst wird diese Aufgabe bei einer Verbundpackung nach dem Oberbegriff von Patentanspruch 1 dadurch, dass das Packungsgiebelpanel im Wesentlichen die Form einer Ellipse aufweist. Geometrisch ideal schließt eine Ellipse durch eine spezielle Kurve eine ebene Fläche ein. Wenn hier von "Ellipse" die Rede ist, so meint dies stets ihre allgemeinste Form, die mindestens abschnittsweise gekrümmt und mindestens beinahe vollständig geschlossen ist. Es ist ferner klar, dass eine Verbundpackung der gattungsbildenden Art infolge ihrer Materialbeschaffenheit, Herstellungsprozesse und Fertigungstoleranzen sich einer mathematischen Idealform lediglich annähern kann. Eine mindestens beinahe geschlossene (also stetige) Kantenkontur des Packungsgiebelpanels ermöglicht eine gute Annäherung an eine Ebene. Harte Spannungsübergänge im Packungslaminat werden durch die Krümmung der Packungskanten minimiert, was sich positiv auf die Formintegrität und Festigkeit der Packung auswirkt. Schließlich werden so auch die Falzvorgänge bei der Formung und Ausbildung der Verbundpackung erleichtert und verbessert.This object is achieved in a composite package according to the preamble of claim 1, characterized in that the Packungsgiebelpanel has substantially the shape of an ellipse. Geometrically ideal, an ellipse encloses a flat surface through a special curve. When this is referred to as "ellipse," this always means its most general form, which is at least partially curved and at least almost completely closed. It is also clear that a composite package of the generic type due to their material properties, manufacturing processes and manufacturing tolerances can only approximate a mathematical ideal form. An at least almost closed (ie continuous) edge contour of the packing gable panel allows a good approach to a plane. Hard voltage transients in the package laminate are minimized by the curvature of the packaging edges, which has a positive effect on the shape integrity and strength of the package Pack affects. Finally, so the folding operations in the formation and formation of the composite package are facilitated and improved.

Gelöst wird die der Erfindung zugrunde liegende Aufgabe zudem durch ein Packungslaminat, das so beschaffen ist, dass es sich zur Herstellung einer solchen Verbundpackung eignet.The problem underlying the invention is also solved by a packing laminate which is such that it is suitable for producing such a composite package.

Der erfindungsgemäße Packungsmantelrohling ist schließlich so beschaffen, dass eine solche Verbundpackung herstellbar ist.The packing jacket blank according to the invention is finally such that such a composite package can be produced.

Eine weitere Lehre der Erfindung sieht vor, dass das Packungsgiebelpanel im Wesentlichen die Form eines Kreises aufweist. Der einfachste Fall einer Ellipse ist der Kreis, bei dem die Brennpunkte im Kreismittelpunkt zusammenfallen. Die stetige und konstant gekrümmte Kreiskontur des Panels verteilt die Spannungen im Material besonders gut.Another teaching of the invention provides that the packing gable panel has substantially the shape of a circle. The simplest case of an ellipse is the circle where the focal points coincide in the center of the circle. The continuous and constantly curved circular contour of the panel distributes the stresses in the material particularly well.

Nach einer weiteren Ausgestaltung der Erfindung weist das Packungsgiebelpanel im Wesentlichen die Form einer Superellipse auf. Eine Superellipse ist ein "Mittelding" zwischen einer Ellipse und einem Rechteck. Im Wesentlichen ist also die Krümmung im Bereich des Haupt- und Nebenscheitel der Ellipse verkleinert. Die Bereiche sind also örtlich "abgeplattet". Eine solche Annäherung kann zusätzlich zu Spannungsreduktionen und zu einem besser ausgebildeten Panel besonders im Zwischenabschnitt der Ellipsenbrennpunkte führen.According to a further embodiment of the invention, the packing gable panel substantially in the form of a superellipse. A superellipse is a "middle thing" between an ellipse and a rectangle. In essence, therefore, the curvature in the region of the major and minor vertices of the ellipse is reduced. The areas are so locally "flattened". Such an approximation may result in addition to stress reductions and to a better formed panel especially in the intermediate section of the ellipse focal points.

In weiterer vorteilhafter Ausführung weist das superellipsoide Packungsgiebelpanel wenigstens zwei zueinander parallele Abschnitte auf. Solche abschnittsweise geraden Konturen können je nach Packungsform gewünscht oder geboten sein, da eine besonders gute Falzung an solchen Stellen ausgebildet sein muss.In a further advantageous embodiment, the super-ellipsoid packing gable panel has at least two mutually parallel sections. Such sections of straight contours may be desired or required, depending on the package form, since a particularly good fold must be formed at such locations.

Nach einer weiteren Lehre der Erfindung bildet das Packungspanel wenigstens zwischen den parallelen Abschnitten eine Ebene, so dass diese beispielsweise als vorteilhafte Funktionsfläche bereitsteht. So lassen sich etwa auf ebenen Abschnitten vereinfacht Ausgießelemente anbringen oder besonders geeignete Sollöffnungsstellen für Strohhalme bilden. Ebenso kann ein zur Ebene stimmiges Dekor eine besondere Ästhetik der Packung entfalten.According to a further teaching of the invention, the packing panel forms a plane at least between the parallel sections, so that these, for example, as advantageous functional surface is available. For example, it is possible to attach pouring elements on flat sections in a simplified manner or to form particularly suitable target opening points for straws. Similarly, a consistent to the level decor can develop a special aesthetics of the pack.

Eine weitere zweckmäßige Ausgestaltung der Erfindung sieht vor, dass der Packungsgiebel eine Quersiegelnaht aufweist. Wird die Packung im Kopfbereich verschlossen, kann die Verbindungsnaht gleich zur Bildung unterschiedener Panele dienen und diese teilweise mitdefinieren.A further expedient embodiment of the invention provides that the packing gable has a transverse sealing seam. If the pack is closed in the head area, the connecting seam can be used to form differentiated panels and partially define them.

Eine weitere Ausführung der Erfindung sieht vor, dass die parallelen Abschnitte der Superellipse durch Abschnitte der Vorderkante und der Quersiegelnaht gebildet sind, so dass auf zusätzliche Rillungen in diesen Bereichen verzichtet werden kann.A further embodiment of the invention provides that the parallel sections of the superellipse are formed by sections of the front edge and the transverse sealing seam, so that it is possible to dispense with additional grooves in these areas.

Eine andere Lehre der Erfindung sieht vor, dass das Packungsgiebelpanel oder auch gleich der ganze Packungsgiebel gegenüber dem Packungsgrundkörper abgeschrägt ist. Sollen auch bei einer erfindungsgemäßen gekrümmten Vorderkante des Packungspanels parallele Rillungen und Zuschnitte des Packungslaminats und Packmantelrohlinge möglich bleiben, muss dieses nach vorne hin abgeschrägt werden. Dies erleichtert deren Herstellung. Abgeschrägte Panele und/oder ganze abgeschrägte Giebelbereiche bieten zudem den Vorteil vergrößerter Displayflächen und maximieren beispielsweise den zur Verfügung stehenden Platz für aufzubringende Ausgießer.Another teaching of the invention provides that the Packungsgiebelpanel or equal to the whole packing gable is chamfered relative to the package body. If parallel creases and blanks of the pack laminate and pack blank blanks are to remain possible even with a curved front edge of the packing panel according to the invention, this must be beveled towards the front. This facilitates their production. Beveled panels and / or entire beveled gable areas also offer the advantage of enlarged display surfaces and maximize, for example, the available space for applied spouts.

Weitere Arten der erfindungsgemäßen Ausführungen sehen vor, dass das Packungsgiebelpanel eine konzentrische Schwächung des Packungslaminats aufweist und ggf. ein Ausgießelement angebracht ist. Ausgießelemente oder eine Sollstechstelle für Strohhalme benötigen in der Regel eine lokale - vorteilhafterweise im Zentrum des Packungspanels - in das Packungslaminat eingebrachte Schwächung.Other types of embodiments according to the invention provide that the packing gable panel has a concentric weakening of the package laminate and, if appropriate, a pouring element is attached. Pouring elements or a desired pier for straws usually require a local - advantageously in the center of the package panel - introduced into the package laminate weakening.

Nach einer weiteren zweckmäßigen Ausführungsform sind zwei Ergänzungspanele zwischen Quersiegelnaht und Ellipse ausgebildet. Werden die Übergänge zwischen gerader Siegelnaht und Ellipsenrundungen durch entsprechende Panele überbrückt, können sich diese wölben und Spannungen im Material reduzieren und helfen, ein formstabiles Packungsgiebelpanel zu gewährleisten.According to a further expedient embodiment, two supplementary panels are formed between transverse sealing seam and ellipse. Will the transitions between Straight seam and elliptical fillets bridged by appropriate panels, these can buckle and reduce stresses in the material and help to ensure a dimensionally stable packing gable panel.

Eine weitere Ausbildung der Verbundverpackung sieht vor, dass die Vorderkante seitlich zwei hochragende lokale Spitzen bilden. Solche entstehen beispielsweise dann, wenn vorne keine Ergänzungspanele zwischen Giebelpanel und Packungsvorderseite vorgesehen sind. Solche Spitzen verleihen der Packung allgemein und dem Packungsgiebel im Besonderen eine gute Festigkeit, insbesondere auch dann wenn die Packungsvorderseite eine gewölbte Fläche ohne definierte vordere Packungskante am Packungsgrundkörper bildet.Another embodiment of the composite packaging provides that the front edge laterally form two towering local peaks. Such arise, for example, when the front no additional panels between gable panel and pack front page are provided. Such tips give the package in general and the packing gable in particular a good strength, especially if the package front side forms a curved surface without a defined front packing edge on the package body.

Die in Figur 1 dargestellte Ausführungsform einer erfindungsgemäßen Verbundpackung P ist durch einen Packungsgrundkörper 1, einen ihn verschließenden Packungsboden 2 und einen den Kopfteil der Packung bildenden Packungsgiebel 3 gebildet. Alle drei Teile sind durch umformende Falzvorgänge aus ein und demselben Packungsmaterial geformt. So ist der Packungsboden 2 einer Verpackungsmaschine auf einem Falzdorn über Packungsfalzlinien 8 geformt und mittels Ultraschall verschlossen (alternativ sind beispielsweise Heißluft, Kleben, etc. denkbar). Das bodenverschlossene Verpackungshalbzeug wird dann über den offenen Kopfbereich mit einem gewünschten Packgut befüllt und sodann über weitere Packungsfalzlinien 8 ein zum Packungsgrundkörper 1 nach vorne abgeschrägter Packungsgiebel 3 ausgebildet, der mittels einer ultraschallgeschweißten Quersiegelnaht 12 die Packung verschließt. Die bei der Ausformung des Packungsgiebels 3 entstehenden überschüssigen Packungsmaterialabschnitte bilden Packungsohren 13, die über Falzungen an den Packungsgrundkörper 1 umgelegt und an dessen die Seitenwand befestigt sind. Durch die Falz- und Formvorgänge entstehen an der Verbundpackung P verschiedene definierte Packungskanten 5. In gezeigter Ausführung ist am Packungsgiebel 3 ein Ausgießelement 15 angebracht, aus dem das Produkt ausgegossen werden kann.In the FIG. 1 illustrated embodiment of a composite package P according to the invention is formed by a pack base body 1, a packing bottom 2 closing it and a packing gable 3 forming the top part of the pack. All three parts are formed by forming folding operations from the same packing material. Thus, the package bottom 2 of a packaging machine is formed on a folding mandrel via packing fold lines 8 and closed by means of ultrasound (alternatively, for example, hot air, gluing, etc. are conceivable). The bottom-closed packaging semifinished product is then filled via the open head region with a desired packaged goods and then formed on other Packungsfalzlinien 8 to the package body 1 forward beveled Packungsgiebel 3, which closes the package by means of an ultrasonic welded transverse seal 12. The resulting in the formation of the Packungsgiebels 3 excess packing material sections form packing tubes 13, which are folded over folds to the package body 1 and attached to the side wall. The folding and forming processes produce different defined packing edges 5 on the composite package P. In the embodiment shown, a pouring element 15 is attached to the packing gable 3 from which the product can be poured out.

Der Darstellung der Figur 2 ist das Ausgießelement ausgeblendet, so dass eine lokale Schwächung 14 des Packungsmaterials (vgl. Erläuterungen weiter unten) und das Packungsgiebelpanel 4 gut sichtbar sind. Gut zu erkennen ist, dass das Packungsgiebelpanel 4 gegenüber dem ohnehin schon abgeschrägten Packungsgiebel 3 zusätzlich abgeschrägt ist. Der vordere Abschnitt des Packungsgiebelpanels 4 bildet eine teilweise gekrümmte Vorderkante 6, die durch ihre Falzung eine spezielle Packungskante 5 zum Packungsgrundkörper 1 definiert. Diese Vorderkante 6 läuft seitlich in lokale Spitzen 31, 32 über, die die vorderen Packungsgiebelecken bilden und die Vorderkante 6 stets überragen. Diese bilden sich durch das zusätzliche Abschrägen des Packungsgiebelpanels 4.The representation of the FIG. 2 the pouring element is hidden, so that a local weakening 14 of the packing material (see explanations below) and the packing gable panel 4 are clearly visible. Good to see that the Packungsgiebelpanel 4 is additionally bevelled in relation to the already gable Packungsgiebel 3. The front portion of the package gable panel 4 forms a partially curved leading edge 6, which by their folding a special Pack edge 5 to the package body 1 defined. This front edge 6 runs laterally into local tips 31, 32, which form the front packing gable corners and always project beyond the front edge 6. These are formed by the additional bevelling of the package gable panel 4.

Figur 3 zeigt das Packungsgiebelpanel 4 in senkrechter Draufsicht. Die Kontur beschreibt die Form einer Superellipse 43. Es sind zwei zueinander erste parallele Abschnitte 44 ausgebildet, wobei der vordere zugleich einen Teil der Vorderkante 6 des Packungsgiebels 3 zum vorderen Packungsgrundkörper 1 bildet und der hintere die Fußbereichsfalzung der Quersiegelnaht 12. Ferner fallen zwei weitere parallele Abschnitte 44' des Packungsgiebelpanels 4 abschnittsweise mit den seitlichen Packungsgiebel-Packungskanten 5 zusammen. Zwischen den ersten parallelen Abschnitten 44 erstreckt sich eine Ebene 45 (strichliniert angedeutet), die zentrisch die Schwächung 14 des Packungsmaterials aufnimmt und peripher die Applikationsfläche für das in Figur 1 gezeigte Ausgießelement 15 bietet. FIG. 3 shows the Packungsgiebelpanel 4 in a vertical plan view. The contour describes the shape of a superellipse 43. There are two mutually first parallel sections 44, wherein the front forms at the same time a part of the front edge 6 of the Packungsgiebels 3 to the front packing main body 1 and the rear the Fußbereichsfalzung the transverse sealing seam 12. Further fall two more parallel Sections 44 'of the Packungsgiebelpanels 4 in sections with the lateral Packungsgiebel-Packungskanten 5 together. Between the first parallel portions 44 extends a plane 45 (indicated by dashed lines), which centrally receives the weakening 14 of the packing material and peripherally the application surface for the in FIG. 1 shown pouring element 15 offers.

In Figur 4 ist der geschichtete Aufbau des Packungsmaterials mit einer Kartonträgerschicht 16 dargestellt, die beidseitig mit einer Polymerschicht 17 laminiert ist. Die Schwächung 14 ist im gezeigten und insofern bevorzugten Ausführungsbeispiel als überbeschichtetes Loch ausgeführt. Dabei wird der Kartonträgerschicht 16 vor dem Laminierungsprozess ein Loch ausgestanzt, so dass beim fertigen Packungsmaterial die lokale Schwächung 14 nur durch die Polymerschichten 17 gebildet ist.In FIG. 4 the layered structure of the packing material is shown with a cardboard carrier layer 16 which is laminated on both sides with a polymer layer 17. The weakening 14 is executed in the shown and in the extent preferred embodiment as an over-coated hole. In this case, the cardboard carrier layer 16 is punched out a hole before the lamination process, so that in the finished packing material, the local weakening 14 is formed only by the polymer layers 17.

Figur 5 zeigt ein Intervall des mit Rillungen 7 versehenen Packungsmaterials als verwendungsfertiges Packungslaminat L zur Ausbildung einer Verbundpackung P. Die Rillungen 7 definieren die späteren Falt- und Falzlinien 8 für den Transport und die Packungsherstellung vor, wovon einige die späteren Packungskanten 5 bilden. Das Packungslaminat L ist ferner mit einem - nicht dargestellten - Dekor bedruckt und liegt zunächst als Endlosmaterial (Rollenware) vor. FIG. 5 shows an interval of the grooved 7 packing material as a ready-to-use packing laminate L to form a composite package P. The groovings 7 define the later folding and folding lines 8 for transport and package manufacture, some of which form the later packing edges 5. The package laminate L is further printed with a - not shown - decor and is initially available as continuous material (rolls).

In Figur 6a und Figur 6b ist die Ober- und Unterseite der auf das Intervall einer zu schaffenden Verbundpackung P zugeschnittene und über die Längsnaht 18 zu einem Rohr verbundene Packungsmantelrohling M zu sehen. Dieser ist über seitliche Faltlinien für einen platzökonomischen Versand (etwa in einer Kartonage) flachgelegt. Der Packungsmantelrohling M wird schließlich einer (hier im Mantelverfahren arbeitenden) Verpackungsmaschine zugeführt, der die Verbundpackung P ausformt, befüllt und verschließt.In Figure 6a and Figure 6b is the top and bottom of the tailored to the interval of a composite package P to be created and over the longitudinal seam 18 to a tube connected packing jacket blank M to see. This is flattened over lateral fold lines for a space economic dispatch (approximately in a cardboard box). The packing jacket blank M is finally fed to a (working here in the shell method) packaging machine, which forms the composite package P, filled and sealed.
