Description

Die vorliegende Erfindung betrifft eine Beutelpackung mit Aufreisshilfe gemäss dem Oberbegriff des Patentanspruchs 1.The present invention relates to a bag pack with a tear-open aid according to the preamble of patent claim 1.

Beutelpackungen für Nahrungsmittel sind oft mit einer gesiegelten Längsnaht und zwei diese kreuzenden gesiegelten Quernähten versehen, die nicht ohne weiteres mit den Fingern geöffnet werden können. Um das Aufreissen der Beutelpackungen zu erleichtern, sind sie in der Regel mit Aufreisshilfen versehen, die jedoch mehr oder weniger aufwendig sind.Pouch packs for food are often provided with a sealed longitudinal seam and two sealed transverse seams crossing them, which cannot be easily opened with the fingers. In order to make it easier to tear open the bag packs, they are usually provided with tear-open aids, which, however, are more or less complex.

Es ist daher die Aufgabe der vorliegenden Erfindung eine andersartige Beutelpackung mit einer Aufreisshilfe zu schaffen, die weniger aufwendig sein soll.It is therefore the object of the present invention to provide a different type of bag pack with a tear-open aid, which should be less expensive.

Diese Aufgabe wird erfindungsgemäss durch eine Aufreisshilfe mit den im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmalen gelöst.This object is achieved according to the invention by means of a tear-open aid with the features specified in the characterizing part of claim 1.

Die in den Figuren 1 bis 3 dargestellte flache Beutelpackung 1 besteht grundsätzlich aus einer länglichen gefalteten Verpackungsfolie mit einer oberen Seite 2, einer Faltungskante 3 und einer unteren Seite 4. Die länglichen Ränder der Seiten 2 und 4 sind entlang einer Längsnaht 5 gegeneinander verschlossen, so dass dadurch eine längliche Hülse gebildet wird, in die ein Produkt, beispielsweise Zucker oder ein Kaffeepulver aufbewahrt werden kann. Die zwei Enden dieser länglichen Hülse können durch Siegelung der schmalen Ränder der Seiten 2 und 4 geschlossen werden, um durch Quernähte 6 und 7 eine dichte Verpackung für dieses Produkt herzustellen, derart, dass der Inhalt der Packung gegen den Zutritt von Luft geschützt bleibt. Im Bereich, wo sich die Quernaht 7 und die Längsnaht 5 kreuzen, weist die Quernaht 7 eine Verbreiterung 8 auf, in der sich eine Aufreisskerbe 9 befindet, die verschiedene Folienlagen durchtrennt. Vorzugsweise ist der Abstand zwischen der Kerbe 9 und dem äussersten Rand 10 der schmalen Seite der Hülse, wo sich die Quernaht 7 befindet, etwas grösser als die mittlere Breite der Quernaht 7. Zudem dringt der Einschnitt der Kerbe 9 seitlich nicht sehr tief in die Längsnaht 5 hinein, um die Dichtheit der Verpackung nicht zu gefährden. Die Kerbe 9 erleichtert somit das Aufreissen des Endes der Hülse, derart, dass der Konsument mit Leichtigkeit einen Riss produzieren kann, der parallel zur Quernaht 7 verläuft und zu einem völligen Abtrennen eines Endstücks der Hülse führen kann, in dem sich die Quernaht 7 und die Kerbe 9 befinden.The flat bag pack 1 shown in FIGS. 1 to 3 basically consists of an elongated folded packaging film with an upper side 2, a folding edge 3 and a lower side 4. The elongated edges of the sides 2 and 4 are closed against one another along a longitudinal seam 5, so in that an elongated sleeve is formed in which a product, for example sugar or a coffee powder, can be stored. The two ends of this elongated sleeve can be closed by sealing the narrow edges of sides 2 and 4 to create a sealed package for this product by transverse seams 6 and 7, so that the contents of the package remain protected against the entry of air. In the area where the transverse seam 7 and the longitudinal seam 5 intersect, the transverse seam 7 has a widening 8 in which there is a tear-open notch 9 which cuts through different layers of film. Preferably, the distance between the notch 9 and the outermost edge 10 of the narrow side of the sleeve, where the transverse seam 7 is located, is somewhat larger than the average width of the transverse seam 7. In addition, the incision of the notch 9 does not penetrate very deep into the longitudinal seam 5 into the tightness of the packaging not endangered. The notch 9 thus facilitates the tearing open of the end of the sleeve in such a way that the consumer can easily produce a tear which runs parallel to the transverse seam 7 and can lead to a complete separation of an end piece of the sleeve in which the transverse seam 7 and the Notch 9 are located.

Die Längsnaht 5 kann, wie Fig. 5 zeigt, eine Flossennaht mit einer Folienlage 11 an der Hülsenseite 2 und mit drei Folienlagen 12, 13 und 14 an der Hülsenseite 4 sein. In diesem Fall werden durch die Kerbe 9, wie in Fig. 6 dargestellt, die vier Folienlagen 11 bis 14 durchtrennt. In Fig. 6 ist die Verbreiterung 8 durch zwei Geraden 15 und 16 abgegrenzt, die einen stumpfen Winkel bilden, wobei die Gerade 15 parallel zur Linie 10 verläuft, so dass gemäss dieser Variante die Kerbe 9 relativ kurz ist, da sie sich nur im Bereich der Längsnaht 5 befindet. Im Gegensatz dazu weist die Variante nach Fig.7 eine erweiterte Verbreiterung 8' auf, die durch eine Zickzack-Linie abgegrenzt ist, die aus zwei parallel verlaufenden Geraden 15 und 17 und einer schrägen Verbindungslinie 18 besteht, wobei gemäss dieser Variante die Kerbe 9' relativ lang ist, indem sie einen Einschnitt durch die gesamte Breite der Längsnaht 5 bildet, ohne jedoch den Bereich der Verbreiterung 8' zu verlassen.The longitudinal seam 5 can, as shown in FIG. 5, be a fin seam with a film layer 11 on the sleeve side 2 and with three film layers 12, 13 and 14 on the sleeve side 4. In this case, the notch 9, as shown in FIG. 6, cuts through the four layers of film 11 to 14. 6, the widening 8 is delimited by two straight lines 15 and 16 which form an obtuse angle, the straight line 15 running parallel to the line 10, so that according to this variant the notch 9 is relatively short, since it is only in the area the longitudinal seam 5 is located. In contrast to this, the variant according to FIG. 7 has an enlarged widening 8 ', which is delimited by a zigzag line, which consists of two parallel straight lines 15 and 17 and an oblique connecting line 18, according to this variant the notch 9' is relatively long in that it forms an incision through the entire width of the longitudinal seam 5, but without leaving the area of the widening 8 '.

In der Ausführung nach Fig. 5 ist die Flossenlängsnaht nach aussen gelegt. Gemäss der Erfindung kann sie, wie in Fig. 8 dargestellt, auch nach innen gelegt sein. Die Längsnaht 5 nach Fig. 8 weist ebenfalls eine Folienlage 11' an der Hülsenseite 2 und drei Folienlagen 12', 13' und 14' an der Hülsenseite 4 auf. In diesem Fall werden durch die Kerbe 9'', wie in Fig. 9 dargestellt, ebenfalls die vier Folienlagen 11' bis 14' durchtrennt. In Fig. 9 ist die Verbreiterung 8'' durch eine Zickzack-Linie abgegrenzt, die aus zwei parallel verlaufenden Geraden 15' und 17' und einer transversalen Verbindungslinie 18' besteht, wobei gemäss dieser Variante die Kerbe 9'' relativ kurz ist, indem sie einen Einschnitt bildet, der sich nur im Bereich der Längsnaht 5 befindet, da wie in Fig. 9 dargestellt, auch eine relativ enge Verbreiterung 8'' möglich ist. Dabei könnte die Ausführung nach Fig. 8 mit den Varianten gemäss Fig. 6 oder 7 oder die Ausführung nach Fig.5 mit der Variante gemäss Fig. 9 realisiert werden.5, the longitudinal fin seam is placed on the outside. According to the invention, as shown in FIG. 8, it can also be placed inwards. The longitudinal seam 5 according to FIG. 8 also has a film layer 11 'on the sleeve side 2 and three film layers 12', 13 'and 14' on the sleeve side 4. In this case, the notch 9 ″, as shown in FIG. 9, likewise cuts through the four film layers 11 ′ to 14 ′. In FIG. 9, the widening 8 ″ is delimited by a zigzag line, which consists of two parallel straight lines 15 ′ and 17 ′ and a transverse connecting line 18 ′, according to this variant the Notch 9 ″ is relatively short in that it forms an incision that is only in the area of the longitudinal seam 5, since, as shown in FIG. 9, a relatively narrow widening 8 ″ is also possible. The embodiment according to FIG. 8 could be implemented with the variants according to FIG. 6 or 7 or the embodiment according to FIG. 5 with the variant according to FIG. 9.

Die Beutelpackung nach den Figuren 10 bis 12 weist eine Längsnaht 5' und zwei Quernähte 6' und 7' auf, die den Nähten 5, 6 bzw. 7 bei den Ausführungen nach den Figuren 1 bis 9 und Figuren 13 bis 16 entsprechen. Die Quernähte 6' und 7' sind jedoch in rechtwinklig zueinander stehende Ebenen gesiegelt, so dass eine Beutelpackung entsteht, die nicht mehr flach, sondern als ein längliches Tetraeder mit abgerundeten Kanten ausgestaltet ist, was einen Beutel mit einem grösseren Füllvolumen ergibt. Die Hülse der Beutelpackung nach Fig. 10, 11, 12 kann durch dasselbe Verfahren wie die Hülse nach Fig. 1, 2, 3 hergestellt werden. Ein solches Verfahren kann beispielsweise darin bestehen, dass ein flaches Einschlagmaterialband über eine Formeinrichtung gezogen wird, so dass sich die Hülse bilden kann, dass nachher die zwei länglichen Folienränder mit Hilfe einer Siegeleinrichtung als eine Längsnaht 5' miteinander verbunden werden, dass danach das so gebildete Rohr vorgeschoben und an bestimmten Stellen zusammengeguetscht, quergesiegelt und gekerbt wird, und dass schliesslich der vorderste Beutel derart mit einer Trenneinrichtung abgetrennt wird, dass die nachlaufende Beutelöffnung unter eine Produktdosiereinrichtung gefördert wird, um den Beutel zu füllen, worauf diese Seite des Beutels mit einer zweiten Quernaht verschlossen wird. Gegebenenfalls kann nachträglich eine zweite Kerbung in der zweiten Quernaht angebracht werden.The bag pack according to FIGS. 10 to 12 has a longitudinal seam 5 'and two transverse seams 6' and 7 'which correspond to seams 5, 6 and 7 in the embodiments according to FIGS. 1 to 9 and FIGS. 13 to 16. The transverse seams 6 'and 7', however, are sealed in planes at right angles to one another, so that a bag pack is formed which is no longer flat, but is designed as an elongated tetrahedron with rounded edges, which results in a bag with a larger filling volume. 10, 11, 12 can be produced by the same method as the sleeve according to FIGS. 1, 2, 3. Such a method can consist, for example, in that a flat wrapping material band is pulled over a shaping device so that the sleeve can form, that the two elongated film edges are subsequently connected to one another as a longitudinal seam 5 ′ with the aid of a sealing device, so that the thus formed Tube is advanced and squeezed together at certain points, cross-sealed and notched, and finally the foremost bag is separated with a separating device in such a way that the trailing bag opening is conveyed under a product metering device in order to fill the bag, whereupon this side of the bag is filled with a second one Cross seam is closed. If necessary, a second notch can be made in the second transverse seam.

Die Längsnaht 5 kann, wie in Fig. 13 dargestellt, eine Überlappungsnaht mit einer Folienlage 22 der einen Hülsenrandseite zwischen einer Folienlage 21 und einem Streifen 23 der anderen Hülsenrandseite sein. In diesem Fall werden durch die Kerbe 29 oder 29', wie in Fig. 15 bzw. 16 dargestellt, insgesamt drei Folienlagen 21, 22, 23 durchtrennt.The longitudinal seam 5 can, as shown in FIG. 13, an overlap seam with a film layer 22 on one side of the sleeve edge between a film layer 21 and a strip 23 the other side of the sleeve. In this case, a total of three film layers 21, 22, 23 are cut through the notch 29 or 29 ', as shown in FIGS. 15 and 16, respectively.

Die Längsnaht 5 kann, wie in Fig. 14 dargestellt, eine Überlappungsnaht mit zwei eine Faltung bildenden Folienlagen 21' und 22' der einen Hülsenrandseite sein, derart, dass eine dritte Folienlage 22' auf der Folienlage oder dem Streifen 23' angeordnet ist. In diesem Fall werden durch die Kerbe 29 oder 29', wie in Fig. 15 oder 16 dargestellt, ebenfalls drei Folienlagen 21', 22', 23' durchtrennt. In Fig. 15 ist die Verbreiterung 28 durch eine Zickzack-Linie abgegrenzt, die aus zwei parallel verlaufenden Geraden 31 und 32 und einer schrägen Verbindungslinie 33 besteht, wobei gemäss dieser Variante die Kerbe 29 relativ kurz ist, da sie sich nur im Bereich der Längsnaht 5 befindet. In Fig. 16 ist die Verbreiterung 28' durch eine Zickzack-Linie abgegrenzt, die aus zwei parallel verlaufenden Geraden 31' und 32' und einer schrägen Verbindungslinie 33' besteht, wobei gemäss dieser Variante die Kerbe 29' relativ lang ist, indem sie einen Einschnitt durch die gesamte Breite der Längsnaht 5 bildet, ohne jedoch den Bereich der Verbreiterung 28' zu verlassen. Aus dem Gesagten geht hervor, dass jede Ausführung nach einer der Figuren 5, 8, 13 oder 14 mit jeder Variante nach einer der Figuren 6, 7, 9, 15 oder 16 kombinierbar ist, und zwar sowohl für den Beutelpackungstyp nach Fig. 1,2,3 oder nach Fig. 10, 11,12.The longitudinal seam 5, as shown in FIG. 14, can be an overlap seam with two foil layers 21 'and 22' forming a fold on one side of the sleeve, such that a third foil layer 22 'is arranged on the foil layer or the strip 23'. In this case, the notch 29 or 29 ', as shown in FIG. 15 or 16, also cuts three film layers 21', 22 ', 23'. 15, the widening 28 is delimited by a zigzag line, which consists of two parallel straight lines 31 and 32 and an oblique connecting line 33, the notch 29 being relatively short according to this variant, since it is only in the area of the longitudinal seam 5 is located. 16, the widening 28 'is delimited by a zigzag line, which consists of two parallel straight lines 31' and 32 'and an oblique connecting line 33', according to this variant the notch 29 'is relatively long by one Incision through the entire width of the longitudinal seam 5 forms, but without leaving the area of the widening 28 '. From what has been said, it can be seen that each embodiment according to one of FIGS. 5, 8, 13 or 14 can be combined with any variant according to one of FIGS. 6, 7, 9, 15 or 16, both for the bag pack type according to FIG. 1, 2,3 or according to Fig. 10, 11,12.

Die Vorteile der erfindungsgemässen Beutelpackung sind darin zu erblicken, dass damit eine Mehrmaterial vermeidende, bedienungsleichte Aufreisshilfe für Beutel mit Längs- und Quernähten geschaffen wird, die verschiedene Siegelschichten aufweisen. Bedienungsleicht in diesem Zusammenhang bedeutet, dass auch schwer aufreissbare Folien, beispielsweise aus Polyester, Polypropylen oder sogenanntes OPP (oriented Polypropylene) mit geringer Kraft aufgerissen werden können, und dass der Ausschüttquerschnitt gross ist. Über 50% der Beutelbreite soll abreissbar sein, was besonders wichtig bei schmalen, länglichen Beuteln mit einem Verhältnis von Breite zu Länge von beispielsweise 1 : 5 oder auch bei normalen Beuteln mit einem schlecht ausfliessenden Inhalt wie Suppen ist.The advantages of the bag pack according to the invention can be seen in the fact that a tear-open aid which avoids multi-material and is easy to use is created for bags with longitudinal and transverse seams which have different sealing layers. Easy to use in this context means that even films that are difficult to tear open, for example made of polyester, polypropylene or so-called OPP (oriented polypropylene), can be torn with little force, and that the distribution cross section is large. More than 50% of the bag width should be able to be torn off, which is particularly important in the case of narrow, elongated bags with a ratio of width to length of, for example, 1: 5 or also in the case of normal bags with a poorly flowing content such as soups.

In den Figuren 6, 7, 9, 15 und 16 ist jeweils eine Kerbe 9, 9', 9'', 29 oder 29' dargestellt, die senkrecht zur Kante der Längsnaht 5 angebracht ist. Bei einer Beutelpackung nach einer der vorhergehend beschriebenen Arten, Ausführungen und Varianten kann jedoch die Aufreisskerbe auch einen Winkel mit der länglichen Längsnaht bilden, so dass es in einem solchen Fall nicht unbedingt notwendig ist, dass sich die Aufreisskerbe der Beutelpackung im Bereich der Verbreiterung 8, 8', 8'', 28 oder 28' der Quernaht 5 befindet. Vorzugsweise soll jedoch bei der erfindungsgemässen Beutelpackung der minimale Abstand zwischen der Aufreisskerbe 9, 9', 9'', 29 oder 29' und dem Beutelinnenraum mindestens 2 mm betragen, um die Dichtheit der Verpackung sicherzustellen.FIGS. 6, 7, 9, 15 and 16 each show a notch 9, 9 ', 9' ', 29 or 29' which is attached perpendicular to the edge of the longitudinal seam 5. In the case of a bag pack according to one of the types, designs and variants described above, however, the tear-open notch can also form an angle with the longitudinal longitudinal seam, so that in such a case it is not absolutely necessary for the tear-open notch of the bag pack to be in the region of the widening 8, 8 ', 8' ', 28 or 28' of the transverse seam 5 is located. Preferably, however, the minimum distance between the tear-open notch 9, 9 ', 9' ', 29 or 29' and the interior of the bag should be at least 2 mm in the inventive bag pack in order to ensure the tightness of the pack.

In den Figuren 5 und 8 sind die Aussenlappen 14 und 14' etwas länger als die Innenlappen 13 bzw. 13' dargestellt, um anzudeuten, dass sie vorzugsweise etwas länger sein sollen, um eine Befestigung der Aussenlappen an der Beutelaussenwand zu erleichtern.5 and 8, the outer tabs 14 and 14 'are shown somewhat longer than the inner tabs 13 and 13', respectively, in order to indicate that they should preferably be somewhat longer in order to facilitate attachment of the outer tabs to the outer wall of the bag.
