Abstract

The rectangular package (1) consists of flexible material, such as a composite plastic film. The one end face of the package has a folding closure (3) and its other end face is closed by a transverse seam (4), the transverse seam and the gusset surfaces (5, 6) formed being placed flatly onto said end face. <IMAGE>

Description

Die Erfindung betrifft eine Rechteckverpackung aus wenigstens einem Zuschnitt aus einer flexiblen Kunststoff-Verbund-Folie, insbesondere für pulverförmiges, granuliertes, pastöses oder stückiges Füllgut, mit wenigstens einer Längsnaht und vier Seitenwänden, wobei an der einen ersten Stirnseite der Verpackung ein Faltverschluß vorgesehen ist, der aus vier an den Seitenwänden angeformten ersten Lappen gefaltet ist, die einander teilweise überlappen.The invention relates to a rectangular packaging made from at least one blank made of a flexible plastic composite film, in particular for powdery, granulated, pasty or lumpy filling material, with at least one longitudinal seam and four side walls, a folding closure being provided on the first end face of the packaging, which is folded from four first flaps formed on the side walls, which partially overlap one another.

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 Verkaufsregalen 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.

In der FR-A-1 304 366 ist bereits eine Rechteckverpackung beschrieben, die einen derartigen Faltverschluß aufweist, die aber den wesentlichen Nachteil beinhaltet, daß sie mit einem derartig gestalteten Verschluß nur dann dicht verschließbar ist, wenn entweder die Verpackung noch leer ist oder aber mit einem festen, klotzförmigen Gegenstand gefüllt ist, der den Druck eines Verschließkolbens aufzunehmen im Stande ist.FR-A-1 304 366 has already described a rectangular packaging which has such a folding closure, but which has the essential disadvantage that it can only be sealed tightly with such a closure if the packaging is either still empty or else is filled with a solid, block-shaped object that is able to absorb the pressure of a sealing piston.

Aus dieser Veröffentlichung ist es auch bekannt, Rechteckverpackungen mit Quersiegelnähten zu verschließen, was zwar für die Dichtigkeit des Verschlußes sehr günstig ist, die Standfestigkeit einer auf diese Quersiegelnaht gestellten Verpackung und vorallem deren Aussehen läßt jedoch sehr zu wünschen übrig.From this publication it is also known to close rectangular packagings with transverse sealing seams, which is very favorable for the tightness of the closure, but the stability of a packaging placed on this transverse sealing seam and, above all, its appearance leaves much to be desired.

Zum dichten Verschließen ist es notwendig, derartige Verpackungen an dem zuletzt zu verschließenden Packungsende mit einer Quersiegelnaht zu versehen, da ein Faltverschluß nicht abzudichten wäre.For tight sealing, it is necessary to provide such packaging with a transverse sealing seam at the end of the package to be closed, since a folding closure would not have to be sealed.

Auch solche Quersiegelnähte sind an sich bekannt, doch läßt sich mit den bekannten Ausführungen keine Standsicherheit der fertigen Verpackung erzielen.Such transverse sealing seams are also known per se, but no stability of the finished packaging can be achieved with the known designs.

Der Erfindung liegt daher die Aufgabe zugrunde eine Rechteckverpackung sowie ein Verfahren zum Aufrichten, Befüllen und Schließen dieser Verpackung zu schaffen, so daß die Verpackung aus preiswertem Material und ohne Umkarton herstellbar ist, auch mit stückigem und scharfkantigem Füllgut dicht verschließbar ist und eine gute Standfestigkeit aufweist, obwohl der Endverschluß am Boden verdeckt angeordnet werden soll.The invention is therefore based on the object of creating a rectangular packaging and a method for erecting, filling and closing this packaging, so that the packaging can be produced from inexpensive material and without a carton, can also be tightly sealed with lumpy and sharp-edged filling material and has good stability , although the end closure is to be concealed on the floor.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an der anderen zweiten Stirnseite ein Verschluß vorgesehen ist, der aus zweiten Lappen besteht, die umlaufend zusammenhängend an den Seitenwänden angeformt sind, wobei deren gemeinsame umlaufende Stirnkante durch eine durchgehende Quernaht verbunden ist, deren über die Verpackung überstehende Ecken als Zwickelflächen an die zweite Stirnseite der Verpackung angelegt sind, und daß an dieser mit der Quernaht ausgestatteten zweiten Stirnseite wenigstens an zwei einander gegenüberliegenden Seitenwänden sich in Richtung der Seitenwände fortsetzende Rippen vorgesehen sind, welche durch Einfalten der zweiten Lappen an die Innenseite der Seitenwände gebildet sind, wobei die Rippen so weit über die andere Stirnseite hinausragen, daß die an die andere Stirnseite angelegten Zwickelflächen nicht überstehen.This object is achieved in that a closure is provided on the other second end face, which consists of second tabs, which are integrally formed continuously on the side walls, the common circumferential end edge being connected by a continuous transverse seam, the protruding beyond the packaging Corners are created as gusset surfaces on the second end face of the packaging, and that on this second end face equipped with the transverse seam, at least on two opposite side walls, there are ribs which continue in the direction of the side walls and which are formed by folding in the second flap are formed on the inside of the side walls, the ribs projecting so far beyond the other end side that the gusset surfaces applied to the other end side do not protrude.

Eine derartige Verpackung ist trotz der verwendeten flexiblen Kunststoff-Verbund-Folie sehr formstabil, wodurch sie dem Füllgut einen hervorragenden Schutz gewährt. Darüber hinaus hat sie aufgrund dieser Formstabilität eine sehr gute Maschinengängigkeit, was den Füll- und Verschließvorgang 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 mußte nämlich scharfkantiges Füllgut gebrochen werden, um ein Durchstoßen der Verpackung zu vermeiden. Infolge des nunmehr zur Verfügung stehenden Raumes kann das Füllgut jedoch in seiner ursprünglich vorliegenden Form belassen werden.Despite the flexible plastic composite film used, packaging of this type is very dimensionally stable, as a result of which it provides the filling material with excellent protection. 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 case of the flat bag previously used, sharp-edged contents had to be broken in order to avoid puncturing the packaging. As a result of the space now available, however, the contents can be left in their original form.

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

Dadurch ist die Längsnaht auf besonders einfache Weise und mit großer Festigkeit und Dichtigkeit herstellbar.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.Furthermore, it has proven to be advantageous if the Inside of the flexible material is at least partially provided with a self-sealing surface.

Dadurch ist es besonders einfach, die Quernaht durch Versiegeln herzustellen.This makes it particularly easy to seal the cross seam.

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

Eine weitere günstige Ausgestaltung der Erfindung liegt darin, daß die mit dem Faltverschluß versehene erste Stirnseite auf ihrer Packungs-Außenseite mit einem Folienstück versehen ist.A further advantageous embodiment of the invention is that the first 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 dieser Stirnseite.A closure made of foil, adhesive tape, cardboard or paper results in an additional closure and a further sealing of this 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 ersten Stirnseite vorgesehenen Lappen gegen ein Innenwerkzeug gefaltet und gegeneinander verklebt oder versiegelt werden, worauf die Verpackung mit der noch offenen zweiten Stirnseite nach oben gefüllt wird, und daß daraufhin diese zweite Stirnseite durch eine Quernaht, die als Klebe- oder Siegelnaht hergestellt wird, verschlossen wird, worauf diese von der Verpackung abstehende Naht auf die zweite Stirnseite der Verpackung aufgefaltet 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 the first end face are then folded against an internal tool and glued or sealed against one another, whereupon the packaging with the still open second end face is filled up, and then this second end face is closed by a transverse seam, which is produced as an adhesive or sealed seam, whereupon this seam protruding from the packaging is unfolded onto the second end face of the packaging and the two gusset surfaces that form laterally are 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.

Ein weiteres vorteilhaftes Verfahren ist dadurch gekennzeichnet, daß vor dem Herstellen der Quernaht von den zur Bildung der zweiten 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 method is characterized in that, before the transverse seam is produced, at least two mutually opposite flaps of the flaps provided for forming the second 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 the latter Fold the flaps outwards and against each other to form the cross seam.

Damit wird bei besonders einfachem Verfahrensablauf eine sehr stabile und standfeste Verpackung erzielt.This results in a very stable and stable packaging with a particularly simple process sequence.

Es ist aber auch möglich, daß erfindungsgemäß nach dem Herstellen der Quernaht von den zur Bildung der zweiten 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.It is also possible, however, that according to the invention, after the transverse seam has been produced, at least two mutually opposite flaps of the flaps provided to form the second end face are folded inward at part of their height until they rest against the side wall and are preferably sealed with the latter.

Auch hiermit ist ein rationelles Herstellungsverfahren aufgezeigt, mit dem eine sehr funktionstüchtige Verpackung erzeugt werden kann.This also shows a rational manufacturing process with which a very functional packaging can be produced.

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

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 is a rectangular packaging, which has four side walls 2 and is provided on its upper end with a folding closure 3. On the lower end face - as can be seen from FIG. 2 - a transverse seam 4 is provided, 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 if the packaging material is not particularly easy to fold, but they are not necessary if the material 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 the emergence 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.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.

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.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.
