Description

Die Erfindung betrifft eine Rechteckverpackung aus wenigstens einem Zuschnitt aus flexiblem Material, wie z.B. einer Kunststoff-Verbund-Folie, insbesondere für pulverförmiges, granuliertes, pastöses oder stückiges Füllgut, mit wenigstens einer Längsnaht und vier Seitenwänden.The invention relates to a rectangular packaging made from at least one blank made of flexible material, such as e.g. a plastic composite film, in particular for powdery, granulated, pasty or lumpy filling material, with at least one longitudinal seam and four side walls.

Aus flexiblem Material wurden bisher Verpackungen entweder in Beutelform oder als tiefgezogene Behälter mit Deckel hergestellt. Beide Formen haben zwar ihren Zweck erfüllt, jedoch ist sowohl ihre Weiterverpackung in größeren Gebinden als auch die Plazierung in den Verkaufregalen unzweckmäßig.Up to now, packaging has been made of flexible material either in the form of a bag or as a deep-drawn container with a lid. Both forms have served their purpose, but their further packaging in larger containers as well as their placement on the store shelves are inappropriate.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Verpackung aus flexiblem Material vorzuschlagen, welche das zu verpackende Füllgut wenigstens genauso gut schützt, wie die bisher bekannten Verpackungen, die aber darüber hinaus die Weiterverpackung und die Plazierung in Verkaufregalen erleichtert.The invention is therefore based on the object of proposing a packaging made of flexible material which protects the contents to be packed at least as well as the previously known packaging, but which also facilitates further packaging and placement on sales shelves.

Diese Aufgabe wird erfindungsgemäß durch eine Rechteckverpackung gelöst, bei der an der einen Stirnseite ein Faltverschluß vorgesehen ist, der aus vier an den Seitenwänden angeformten Lappen gefaltet ist, die einander teilweise überlappen, und daß die andere Stirnseite eine Quernaht aufweist, deren über die Verpackung überstehende Ecken als Zwickelflächen an die Verpackung angelegt sind.This object is achieved by a rectangular packaging in which a folding closure is provided on one end face, which is folded from four flaps formed on the side walls, which partially overlap one another, and in that the other end face has a transverse seam, the protruding from the packaging Corners are created as gusset areas on the packaging.

Eine derartige Verpackung ist trotz des verwendeten flexiblen Materials formstabil, wodurch sie dem Füllgut einen hervorragenden Schutz gewährt. Darüber hinaus hat sie aufgrund dieser Formstabilität eine sehr gute Maschinengängigkeit, was den Füll- und Verschlußvorgang sehr erleichtert. Gegenüber dem hauptsächlich üblichen Flachbeutel benötigt sie weniger Raum und erheblich weniger Material. In der Formstabilität ist noch ein weiterer Vorteil der vorliegenden Erfindung begründet; beim bisher eingesetzten Flachbeutel führen grobstückige und vor allem scharfkantige Füllgüter zum Durchstoßen der Packung, sodaß diese entweder nicht verwendet werden können oder diese vorgebrochen werden müssen. Infolge des nunmehr zur Verfügung stehenden Raumes kann das Füllgut jedoch in seiner ursprünglich vorliegenden Form belassen werden.Despite the flexible material used, such packaging is dimensionally stable, as a result of which it provides excellent protection for the contents. In addition, due to this dimensional stability, it has very good machinability, which greatly facilitates the filling and closing process. Compared to the mainly conventional flat bag, it requires less space and considerably less material. Another advantage of the present invention is based on the dimensional stability; In the previously used flat bags, coarse and, above all, sharp-edged contents lead to the package being pierced, so that they can either not be used or they have to be pre-broken. As a result of the space that is now available, however, the contents can be left in their original form.

Eine vorteilhafte Ausgestaltung der Erfindung liegt darin, daß die Längsnaht der Verpackung als Überlappungsnaht ausgebildet ist.An advantageous embodiment of the invention is that the longitudinal seam of the packaging is designed as an overlap seam.

Wird diese Längsnaht darüber hinaus gemäß einer weiteren Ausgestaltung der Erfindung im Bereich einer Kante zwischen zwei Seitenwänden vorgesehen, so ist diese fast unsichtbar und in keiner Weise störend.If this longitudinal seam is also provided according to a further embodiment of the invention in the region of an edge between two side walls, this is almost invisible and in no way disturbing.

Bei einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, daß das flexible Material wenigstens im Bereich der Längsnaht beidseitig mit einem Siegelmedium versehen ist.
Dadurch ist die Längsnaht auf besonders einfache Weise und mit großer Festigkeit und Dichtigkeit herstellbar.In an advantageous development of the invention it is provided that the flexible material is provided with a sealing medium on both sides at least in the area of the longitudinal seam.
As a result, the longitudinal seam can be produced in a particularly simple manner and with great strength and tightness.

Weiterhin hat es sich als vorteilhaft erwiesen, wenn die Innenseite des flexiblen Materials wenigstens partiell mit einer gegen sich selbst siegelnden Oberfläche versehen ist.
Dadurch ist es besonders einfach, die Quernaht durch Versiegeln herzustellen.Furthermore, it has proven to be advantageous if the inside of the flexible material is at least partially provided with a self-sealing surface.
This makes it particularly easy to seal the cross seam.

Eine sehr vorteilhafte Weiterbildung der Erfindung ist dadurch gekennzeichnet, daß an der mit der Quernaht ausgestatteten Stirnseite wenigstens an zwei einander gegenüberliegenden Seitenwänden Rippen vorgesehen sind, welche durch Einfalten der Lappen an die Innenseite der Seitenwände gebildet sind.
Durch diese Rippen wird die Standfestigkeit der Verpackung wesentlich erhöht, da die Zwickelflächen in den durch die Rippen gebildeten Freiraum eingefaltet werden können.A very advantageous development of the invention is characterized in that ribs are provided on the end face equipped with the transverse seam on at least two mutually opposite side walls, which are formed by folding in the flaps on the inside of the side walls.
These ribs significantly increase the stability of the packaging, since the gusset surfaces can be folded into the space formed by the ribs.

Die Funktionssicherheit der Rippen wird noch weiter erhöht, wenn erfindungsgemäß die Lappen im Bereich der Rippen an den Seitenwänden angesiegelt sind.The functional reliability of the ribs is further increased if, according to the invention, the tabs are sealed on the side walls in the area of the ribs.

Eine weitere günstige Ausgestaltung der Erfindung liegt darin, daß die mit dem Faltverschluß versehene Stirnseite auf ihrer Packungs-Außenseite mit einem Folienstück versehen ist.A further favorable embodiment of the invention is that the end face provided with the folding closure is provided with a piece of film on the outside of its pack.

Ein Abschluß aus Folie, Klebeband, Karton oder Papier ergibt einen zusätzlichen Verschluß und eine weitere Abdichtung der Stirnseite.A closure made of foil, adhesive tape, cardboard or paper results in an additional closure and a further sealing of the end face.

Das Folienstück kann aber auch oder zusätzlich anderen Zwecken dienen; so ist es beispielsweise möglich, das Folienstück als Wertmarke oder Garantieverschluß auszubilden.The piece of film can also or additionally serve other purposes; it is possible, for example, to design the piece of film as a token or guarantee seal.

Bei einem vorteilhaften Verfahren zum Aufrichten der Verpackung ist vorgesehen, daß das flexible Material entlang einer Längsnaht zu einem schlauchförmigen Gebilde verschlossen wird, daß anschließend die an der einen Stirnseite vorgesehenen Lappen gegen ein Innenwerkzeug gefaltet und gegeneinander verklebt oder versiegelt werden, worauf die Verpackung mit der noch offenen Stirnseite nach oben gefüllt wird, und daß daraufhin diese Stirnseite durch eine Quernaht, die als Klebe- oder Siegelnaht hergestellt wird, verschlossen wird, worauf diese von der Verpackung abstehende Naht auf die Stirnseite der Verpackung gefaltet wird und die beiden sich seitlich bildenden Zwickelflächen an die Verpackung angelegt werden.In an advantageous method for erecting the packaging, it is provided that the flexible material is closed along a longitudinal seam to form a tubular structure, that the flaps provided on one end face are then folded against an internal tool and glued or sealed against one another, whereupon the packaging with the still open face is filled upwards, and then this face is closed by a transverse seam, which is produced as an adhesive or sealed seam, whereupon this seam protruding from the packaging is folded onto the face of the packaging and the two gusset surfaces that form laterally be placed on the packaging.

Dieser Verfahrensablauf ist besonders einfach, wodurch der maschinelle Aufwand sehr gering ist.This process sequence is particularly simple, as a result of which the mechanical outlay is very low.

Eine weitere vorteilhafte Ausgestaltung des Verfahrensablaufes liegt darin, daß vor dem Herstellen der Quernaht von den zur Bildung der Stirnseite vorgesehenen Lappen wenigstens zwei einander gegenüberliegende, auf einem Teil ihrer Höhe ins Innere bis zur Anlage an die Seitenwand eingefaltet und vorzugsweise mit dieser versiegelt werden, worauf diese Lappen wieder nach außen und gegeneinander gefaltet werden, um dann die Quernaht zu bilden.A further advantageous embodiment of the process flow is that before producing the transverse seam, at least two opposing flaps of the flaps provided for the formation of the end face are folded in at part of their height into the interior until they rest against the side wall, and are preferably sealed with the latter, whereupon these Fold the flaps outwards and against each other to form the cross seam.

Außerdem ist es erfindungsgemäß möglich, daß nach dem Herstellen der Quernaht von den zur Bildung der Stirnseite vorgesehenen Lappen wenigstens zwei einander gegenüberliegende auf einem Teil ihrer Höhe ins Innere bis zur Anlage an die Seitenwand eingefaltet und vorzugsweise mit dieser versiegelt werden. Diese Verfahren sind zwar durch die Herstellung der Rippen etwas aufwendiger, doch wird damit eine weitaus größere Standfestigkeit der so hergestellten Verpackung erzielt.In addition, it is possible according to the invention that, after the transverse seam has been produced, at least two mutually opposite flaps of the flaps provided for forming the end face are folded in at part of their height inside until they rest against the side wall and are preferably sealed with the latter. Although these processes are somewhat more complex due to the production of the ribs, the packaging produced in this way is much more stable.

Sehr vorteilhaft ist auch die erfindungsgemäße Verwendung der Verpackung für das Verpacken von pulverförmigem, granuliertem, pastösem oder stückigem Füllgut, wie z. B. Trockensuppen od.dgl..The use of the packaging according to the invention for packaging powdery, granulated, pasty or lumpy filling material, such as, for. B. dry soups or the like.

In der Zeichnung ist die Erfindung anhand zweier Ausführungsbeispiele veranschaulicht. Dabei zeigen:

  • Fig. 1 ein Schaubild einer Rechteckverpackung mit an der oberen Stirnseite vorgesehenem Faltverschluß,
  • Fig. 2 eine Draufsicht auf die untere Stirnseite der Verpackung, die mit einer Quernaht verschlossen ist und Rippen am Übergang zwischen den Seitenwänden und der Stirnseite aufweist,
  • Fig. 3 eine schematische Ansicht eines Innendornes, um den zur Bildung der Verpackung ein Zuschnitt zu einer schlauchförmigen Hülle gefaltet und entlang einer Längsnaht verschlossen ist,
  • Fig. 4 eine schematische Ansicht einer weiteren Entstehungsstufe der Verpackung mit an der unteren Stirnseite angebrachtem Faltverschluß und angelegtem Siegelwerkzeug,
  • Fig. 5 eine Ansicht der bereits gefüllten Verpackung mit an der oberen Stirnseite angebrachter Quer-Siegel-Naht und
  • Fig. 6 eine Ansicht der Verpackung bei der die Quernaht an die obere Stirnseite eben angelegt ist.
The invention is illustrated in the drawing using two exemplary embodiments. Show:
  • 1 is a diagram of a rectangular packaging with a folding closure provided on the upper end face,
  • 2 is a plan view of the lower end face of the package, which is closed with a transverse seam and has ribs at the transition between the side walls and the end face,
  • 3 shows a schematic view of an inner mandrel, around which a blank is folded to form a tubular casing and closed along a longitudinal seam to form the packaging,
  • 4 shows a schematic view of a further stage in the development of the packaging with the folding closure attached to the lower end face and the sealing tool applied,
  • Fig. 5 is a view of the already filled packaging with cross-seal seam attached to the upper end face and

Mit 1 ist in Fig. 1 eine Rechteckverpackung bezeichnet, die vier Seitenwände 2 aufweist und an ihrer oberen Stirnseite mit einem Faltverschluß 3 versehen ist. An der unteren Stirnseite ist -wie aus Fig. 2 ersichtlich- eine Quernaht 4 vorgesehen, die flach an die Stirnseite angelegt ist. Die beiden entstehenden Zwickelflächen 5 und 6 sind ebenfalls flach an die Stirnseite angelegt. Die Stirnseite ist dabei gegenüber dem Ende der Seitenwände etwas tiefer gelegt, wodurch Rippen 7 gebildet sind. Diese Rippen 7 erhöhen insbesondere bei nicht besonders gut faltbarem Verpackungs-Material die Standfestigkeit der Verpackung, sie sind jedoch bei gut faltbarem Material nicht notwendig.1 in FIG. 1 denotes a rectangular packaging which has four side walls 2 and is provided with a folding closure 3 on its upper end face. As can be seen in FIG. 2, a transverse seam 4 is provided on the lower end face, which is laid flat against the end face. The two resulting gusset surfaces 5 and 6 are also laid flat on the end face. The end face is slightly lower than the end of the side walls, whereby ribs 7 are formed. These ribs 7 increase the stability of the packaging, in particular in the case of packaging material which is not particularly easy to fold, but are not necessary in the case of material which is easy to fold.

In den Fig.3 bis 6 ist die Entstehung einer Verpackung 1 in vier Stufen dargestellt. Dabei ist in Fig. 3 ein Zuschnitt des flexiblen Verpackungs-Materials um einen Innendorn 8 gelegt und entlang einer Längsnaht 9 verschlossen. An die Seitenwände 2 sind Lappen 10 bzw. 11 angeformt, von denen die unteren 10 in Fig. 4 an den Innendorn 8 gefaltet sind und mit einem beheizbaren Siegelwerkzeug 12 angepreßt und damit gegeneinander versiegelt werden. Diese Lappen 10 bilden bei der fertigen Verpackung 1 dann den oberen Faltverschluß 3.3 to 6 show the creation of a packaging 1 represented in four stages. 3, a blank of the flexible packaging material is placed around an inner mandrel 8 and closed along a longitudinal seam 9. Tabs 10 and 11 are formed on the side walls 2, of which the lower 10 in FIG. 4 are folded onto the inner mandrel 8 and pressed with a heatable sealing tool 12 and thus sealed against one another. These flaps 10 then form the upper folding closure 3 in the finished packaging 1.

Nach dem Herstellen dieses Faltverschlusses 3 wird das Siegelwerkzeug 12 und der Innendorn 8 entfernt und in nicht dargestellter Weise das Füllgut in die Verpackung von der noch offenen nach oben stehenden unteren Stirnseite her eingefüllt. Im Anschluß daran wird diese Seite durch die Quernaht 4 verschlossen (Fig.5.). Diese Quernaht 4 wird dann -wie in Fig.6 sichtbar- flach an die Stirnseite angelegt. Dabei bilden sich die Zwickelflächen 5 und 6 aus, die etwa senkrecht nach oben abstehen und anschließend ebenfalls flach an die Stirnseite angelegt werden.
Die fertige und gefüllte Verpackung steht zwar nun auf dem Kopf, was aber keineswegs ein Nachteil ist. Vielmehr wird jetzt eine größere Anzahl von Verpackungen in eine größere Umverpackung mit dem Kopf nach unten eingestellt.After this folding closure 3 has been produced, the sealing tool 12 and the inner mandrel 8 are removed and the filling material is poured into the packaging from the still open, upwardly facing lower end face in a manner not shown. This side is then closed by the transverse seam 4 (Fig. 5). This transverse seam 4 is then - as can be seen in FIG. 6 - placed flat against the end face. The gusset surfaces 5 and 6 are formed, which protrude approximately vertically upwards and are then also placed flat against the end face.
The finished and filled packaging is now upside down, but this is by no means a disadvantage. Rather, a larger number of packages is now placed in a larger outer packaging with the head down.
