In den Figuren 1 bis 3 ist eine ungezwickelte Serienpackung 1 dargestellt, die im wesentlichen aus einer schlauchförmig bearbeiteten Verpackungsfolie besteht, deren Längsränder durch eine Flossennaht 2 miteinander verbunden sind, um eine flache Schlauchbeutelpackung zu bilden. Die obere breite Verpackungswand 3 des derart ausgebildeten Schlauches ist auch durch Quernähte 4, 5, 6 und 7, die von einem Längsrand zum anderen verlaufen, mit der unteren breiten Verpackungswand 8 des Schlauches verbunden, so dass zwischen diesen zwei breiten Verpackungswänden 3 und 8 des Schlauches flache transversal liegende Nahrungsmittelstücke 9, 10 und 11 eingeschlossen sind.1 to 3 show an untwisted series pack 1 which essentially consists of a tubularly processed packaging film, the longitudinal edges of which are connected to one another by a fin seam 2 in order to form a flat tubular bag pack. The upper wide packaging wall 3 of the tube formed in this way is also connected to the lower wide packaging wall 8 of the tube by transverse seams 4, 5, 6 and 7, which run from one longitudinal edge to the other, so that between these two wide packaging walls 3 and 8 of the Hose flat transverse food pieces 9, 10 and 11 are included.

In den Figuren 4 bis 6 ist eine gezwickelte Serienpackung 21 dargestellt, die im wesentlichen aus einer schlauchförmig bearbeiteten Verpackungsfolie besteht, deren Längsränder durch eine Flossennaht 22 miteinander verbunden sind, um eine flache Schlauchbeutelpackung zu bilden. Die obere breite Verpackungswand 23 des derart ausgebildeten Schlauches ist auch durch Quernähte 24, 25, 26 und 27, die von einem Längsrand zum anderen verlaufen, mit der unteren breiten Verpackungswand 28 des Schlauches verbunden, so dass zwischen diesen zwei breiten Verpackungswänden 23 und 28 des Schlauches flache transversal liegende Nahrungsmittelstücke 29, 30 und 31 eingeschlossen sind.FIGS. 4 to 6 show a gusseted series pack 21 which essentially consists of a tubular packaging film, the longitudinal edges of which are connected to one another by a fin seam 22 in order to form a flat tubular bag pack. The upper wide packaging wall 23 of the tube formed in this way is also connected to the lower wide packaging wall 28 of the tube by transverse seams 24, 25, 26 and 27, which run from one longitudinal edge to the other, so that between these two wide packaging walls 23 and 28 of the Hose flat transverse food pieces 29, 30 and 31 are included.

Die Quernähte 4, 5 , 6 und 7 nach Fig. 1 bis 3 und die Quernähte 24, 25, 26 und 27 nach Fig. 4 bis 6 erstrecken sich wie gesagt durch die ganze Breite des Schlauches, um jeweils eine absolut dichte Verpackung zu erzeugen, auch wenn nur ein Einschlagmaterial verwendet wird.The transverse seams 4, 5, 6 and 7 according to FIGS. 1 to 3 and the transverse seams 24, 25, 26 and 27 according to FIGS. 4 to 6 extend, as mentioned, through the entire width of the hose in order to produce an absolutely tight packaging , even if only one wrapping material is used.

Im Bereich der Quernähte 5 und 6 (Fig. 1) bzw. 25 und 26 (Fig. 4) befinden sich längs derselben verlaufende Schwächungslinien 12 und 13 (Fig. 1) bzw. 32 und 33 (Fig. 4), an denen die einzelnen Verpackungseinheiten, in denen sich die Stücke 9, 10 und 11 befinden, einfach abgetrennt werden können. Solche Schwächungslinien können beispielsweise durch Perforationen realisiert werden.In the area of the transverse seams 5 and 6 (FIG. 1) or 25 and 26 (FIG. 4) there are weakening lines 12 and 13 (FIG. 1) or 32 and 33 (FIG. 4) along which the individual packaging units, in which the pieces 9, 10 and 11 are located, can be easily separated. Such lines of weakness can be realized, for example, by perforations.

Im Bereich des Schlauchrandes und parallel zur Längsflossennaht 2 (Fig. 1) ist ein Aufreissstreifen oder Aufreissband 14 angeordnet, und zwar vorzugsweise an der der Längsnaht 2 gegenüberliegenden Verpackungswand 3.A tear strip or tear tape 14 is arranged in the area of the tube edge and parallel to the longitudinal fin seam 2 (FIG. 1), preferably on the packaging wall 3 opposite the longitudinal seam 2.

Im Bereich der Schlauchränder und parallel zur Längsflossennaht 22 (Fig. 4) sind zwei Aufreissstreifen oder Aufreissbänder 34, 34′ angeordnet, und zwar vorzugsweise an der der Längsnaht 22 gegenüberliegenden Verpackungswand 23.In the area of the tube edges and parallel to the longitudinal fin seam 22 (FIG. 4), two tear strips or tear strips 34, 34 'are arranged, preferably on the packaging wall 23 opposite the longitudinal seam 22.

Im Bereich der Stellen, wo sich das Aufreissband 14 bzw. 34 oder 34′ und die Schwächungslinien 12 und 13 bzw. 32 oder 33 kreuzen, sind Aufreisshilfen, beispielsweise in Form von Kerbschnitten oder Einschnitten vorgesehen. In den Figuren 1 und 2 bzw. 4 und 5 sind die Aussenquerflossen mit 4 und 7 bzw. mit 24 und 27 und die Innenquerflossen mit 5 und 6 bzw. mit 25 und 26 bezeichnet. Die Innenquerflossen trennen jeweils zwei Nahrungsmittelstücke, während die Aussenquerflossen sich an den Enden des Schlauchbeutels befinden. Dabei können im Sinne der Erfindung sowohl die Innenquerflossen als auch die Aussenquerflossen jeweils mit gleich- oder ungleichartigen Aufreisshilfen versehen sein.In the area of the points where the tear tape 14 or 34 or 34 'and the lines of weakness 12 and 13 or 32 or 33 cross, tear aids are provided, for example in the form of notch cuts or incisions. In Figures 1 and 2 or 4 and 5, the outer transverse fins are denoted by 4 and 7 or by 24 and 27 and the inner transverse fins by 5 and 6 or by 25 and 26. The inner transverse fins separate two pieces of food, while the outer transverse fins are located at the ends of the tubular bag. For the purposes of the invention, both the inner transverse fins and the outer transverse fins can each be provided with the same or different ripping aids.

Für das Einschlagmaterial und die Art, wie das Aufreissband angeordnet ist, können alle beliebigen Ausführungen gemäss dem Stand der Technik gewählt werden, erfindungsgemäss soll jedoch zunächst das Aufreissband durchgehend, das heisst durch mehrere Verpackungseinheiten hindurch angeordnet sein, und zwar vorzugsweise auf der Verpackungswand geklebt. Die Erfindung ist daher grundsätzlich unabhängig davon, ob und wie der Schlauch beschriftet ist. Vorzugsweise befindet sich jedoch das Aufreissband in einem Abstand von der Packungsmitte, der mindestens 0,6-mal so gross wie die halbe Packungsbreite ist. Solche Aufreissbänder können auch nachträglich zusammen mit den Perforationen der Querflossenschwächung geschwächt oder sogar völlig durchtrennt sein.For the wrapping material and the way in which the tear tape is arranged, any desired designs according to the prior art can be selected, but according to the invention, the tear tape should first be continuous, that is to say arranged through a plurality of packaging units, and preferably glued to the packaging wall. The invention is therefore fundamentally independent of whether and how the hose is labeled. However, the tear tape is preferably at a distance from the center of the pack that is at least 0.6 times as large as half the pack width. Such tear tapes can also be subsequently weakened together with the perforations of the transverse fin weakening or even completely severed.

In der Ausführung nach Fig. 7 weist die Schwächungslinie 32 beispielsweise eine Zick-Zack-Einkerbung 35 auf, die sich im Bereich des Aufreissbandes 34 befindet.7, the weakening line 32 has, for example, a zigzag notch 35 which is located in the region of the tear tape 34.

In der Ausführung nach Fig. 8 weist die Schwächungslinie 40 beispielsweise eine einfache Einkerbung 45 auf, die sich im Bereich des Aufreissbandes 34 befindet.In the embodiment according to FIG. 8, the weakening line 40 has, for example, a simple notch 45, which is located in the region of the tear tape 34.

In der Ausführung nach Fig. 9 weist die Schwächungslinie 50 beispielsweise einen einfachen Einschnitt 55 auf, der sich im Bereich des Aufreissbandes 34 befindet.In the embodiment according to FIG. 9, the weakening line 50 has, for example, a simple incision 55, which is located in the region of the tear tape 34.

In der Ausführung nach Fig. 10 weist die Schwächungslinie 60 beispielsweise eine kurze Unterbrechung 65 auf, die sich im Bereich des Aufreissbandes 34 befindet.In the embodiment according to FIG. 10, the weakening line 60 has, for example, a short interruption 65, which is located in the region of the tear tape 34.

Die Vorteile der Schlauchbeutelpackung mit Aufreisshilfe nach der vorliegenden Erfindung bestehen darin, dass nur ein Einschlagmaterial benötigt wird, dass die Packung mit einer hohen Fabrikationsleistung herstellbar und für die Konsumenten bequem zu öffnen ist, dass das Aufreissband optisch durch Aufdruck kenntlich gemacht werden kann und dass die Einzelpackungen hygienisch sind, weil keine Verschmutzung durch die Perforationen eindringen kann, da jeweils nur eine Portion geöffnet wird und der Rest hygienisch verpackt bleibt.The advantages of the tubular pouch pack with tear-open aid according to the present invention are that only one wrapping material is required, that the pack can be manufactured with a high manufacturing output and is easy to open for consumers, that the tear-open tape can be visually identified by printing and that Individual packs are hygienic because no contamination can penetrate through the perforations, since only one portion is opened at a time and the rest remains hygienically packaged.

Die Einrichtung nach Fig. 11 weist zwei Grossrollen 71 und 72 und zwei kleine Vorratsrollen 73, 74 auf, von denen das Einschlagmaterial 75 bzw. das Aufreissband 76 abgezogen wird. Die zu verpackenden Produkte werden durch einen Förderer 77 zur Verpackungsstation 78 geführt, in der zunächst die Aufreissbänder auf das Einschlagmaterial aufgebracht werden, bevor der Schlauch gefaltet wird. Dann werden die Stücke eingebracht, bevor die Längsnaht erstellt wird. In einer weiteren Station 79 wird nachträglich die Quernaht ausgeführt. Die Querperforierung bzw. die Trennung wird auch in dieser Station 79 oder später durchgeführt.11 has two large rolls 71 and 72 and two small supply rolls 73, 74, from which the wrapping material 75 or the tear tape 76 is pulled off. The products to be packaged are guided by a conveyor 77 to the packing station 78, in which the tear-open tapes are first applied to the wrapping material before the tube is folded. Then the pieces are inserted before the longitudinal seam is created. In a further station 79, the transverse seam is carried out subsequently. The transverse perforation or the separation is also carried out in this station 79 or later.
