Abstract

The foil packing (1) is closed by at least one sealing seam (4) and consists of an upper wall and a lower wall (2) and two side walls (3) which are folded in in a V-shape between the upper wall and the lower wall in the region of the sealing seam (4). A short incision (6) is provided in each case in the tips of the two V-shaped side wall portions. <IMAGE>

Description

Die Erfindung betrifft eine mit wenigstens einer Siegelnaht verschlossene Folienverpackung, die aus einer Ober- und einer Unterwand sowie zwei Seitenwänden besteht, die im Bereich der Siegelnaht V-förmig zwischen Ober- und Unterwand eingefaltet sind.The invention relates to a film packaging closed with at least one sealing seam, which consists of an upper and a lower wall and two side walls which are folded in a V-shape between the upper and lower walls in the area of the sealing seam.

Derartige Verpackungen sind bei zahlreichen Füllgütern im Einsatz, sie haben sich auch bewährt, da sie dem Füllgut einen optimalen Schutz gewähren und darüber hinaus durchaus ansprechend sind. Sie haben jedoch den Nachteil, daß sie ohne ein Werkzeug - wie z.B. eine Schere - nicht zu öffnen sind.Packaging of this type is used in numerous fill goods; they have also proven themselves since they provide the fill goods with optimal protection and are also very appealing. However, they have the disadvantage that without a tool - such as e.g. a pair of scissors - cannot be opened.

Der Erfindung liegt die Aufgabe zugrunde, eine Folienver­packung der genannten Art zu schaffen, die gleich gute Eigenschaften aufweist, aber leicht und ohne Zuhilfenahme von Werkzeugen zu öffnen ist.The invention has for its object to provide a film packaging of the type mentioned, which has the same good properties, but is easy to open and without the use of tools.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in den Spitzen der beiden V-förmig eingefalteten Seitenwand-­Abschnitte jeweils ein kurzer Einschnitt vorgesehen ist. Durch diese kurzen Einschnitte ist ein sehr leichtes Ein­reißen der Folie ermöglicht.This object is achieved in that a short incision is provided in the tips of the two V-shaped folded side wall sections. These short incisions make it very easy to tear the film.

Bei Herstellung der Folienverpackung aus einem wenigstens zweilagigen Folienverbund sind die Einschnitte erfindungs­gemäß in einer der Lagen des Folienverbundes vorgesehen.When the film packaging is produced from an at least two-layer film composite, the incisions are provided according to the invention in one of the layers of the film composite.

Damit wird ohne nachteilige Beeinflussung des Einreißver­haltens die Dichtigkeit der Folienverpackung gewährleistet.This ensures the tightness of the film packaging without adversely affecting the tear behavior.

Sehr vorteilhaft ist es auch, wenn erfindungsgemäß die Länge der Einschnitte so gewählt ist, daß sie vom äußeren Rand bis höchstens in die Siegelnaht reichen.
Dadurch ist die Dichtigkeit der Folienverpackung ebenfalls gewährleistet.It is also very advantageous if, according to the invention, the length of the incisions is chosen so that they extend from the outer edge to at most the sealing seam.
This also ensures the tightness of the film packaging.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung sind die Einschnitte V-förmig ausgebildet.
Dadurch läßt sich die Einreißkraft noch leichter einleiten.According to an advantageous embodiment of the invention, the incisions are V-shaped.
This makes it easier to introduce the tearing force.

Sehr vorteilhaft ist es auch, wenn erfindungsgemäß die mit den Einschnitten versehene Folie eine ausgeprägte Spleiß­fähigkeit in Richtung der Einschnitte aufweist.It is also very advantageous if, according to the invention, the film provided with the incisions has a pronounced ability to be spliced in the direction of the incisions.

Das mit Hilfe der Einschnitte ermöglichte leichte Einreißen wird durch diese Spleißfähigkeit soweit fortgesetzt, daß die Siegelnaht leicht zu öffnen ist.The easy tearing made possible with the help of the incisions is continued by this splicing ability to such an extent that the sealing seam is easy to open.

Die Erfindung ist in der Zeichnung anhand zweier Ausfüh­rungsbeispiele veranschaulicht. Dabei zeigen:

  • Fig. 1 eine schaubildliche Darstellung einer Folienver­packung mit Ober- und Unterwand sowie zwei V-för­mig eingefalteten Seitenwänden,
  • Fig. 2 einen Abschnitt einer auseinandergefalteten Sei­tenwand mit einem Einschnitt und
  • Fig. 3 einen Abschnitt einer weiteren auseinandergefal­teten Seitenwand mit einem V-förmigen Einschnitt.
The invention is illustrated in the drawing using two exemplary embodiments. Show:
  • 1 is a diagrammatic representation of a film packaging with top and bottom walls and two V-shaped folded side walls,
  • Fig. 2 shows a portion of an unfolded side wall with a cut and
  • Fig. 3 shows a portion of another unfolded side wall with a V-shaped incision.

Mit 1 ist in Fig. 1 eine Folienverpackung gekennzeichnet, die aus Ober- und Unterwand 2 sowie zwei Seitenwänden 3 gebildet ist. Die Folienverpackung 1 ist mit einer Siegel­naht 4 verschlossen, in deren Bereich die beiden Seitenwände 3 V-förmig zwischen die Ober- und Unterwand 2 eingefaltet sind.1 in Fig. 1 is a film packaging, which is formed from the top and bottom wall 2 and two side walls 3. The film packaging 1 is closed with a sealing seam 4, in the area of which the two side walls 3 are folded in a V-shape between the upper and lower wall 2.

Wie in Fig. 2 sichtbar, kann diese V-förmige Faltung gera­degezogen werden, wobei die Siegelnaht 4 und der Rand 5 der Verpackung im wesentlichen doppelt-T-förmig verlaufen. Dadurch wird ein in der Spitze dieser V-förmig eingefalteten Seitenwand-Abschnitte vorgesehener Einschnitt 6 sichtbar, der vom Rand 5 her bis in die Siegelnaht 4 reicht.As can be seen in FIG. 2, this V-shaped fold can be pulled straight, the sealing seam 4 and the edge 5 of the packaging being essentially double-T-shaped. This shows an incision 6 provided in the tip of these V-shaped folded-in side wall sections, which extends from the edge 5 into the sealing seam 4.

Das Ausführungsbeispiel nach Fig. 3 unterscheidet sich hiervon dadurch, daß ein V-förmiger Einschnitt 16 vorgesehen ist, der ebenfalls vom Rand 5 bis in die Siegelnaht reicht.The embodiment of FIG. 3 differs from this in that a V-shaped incision 16 is provided, which also extends from the edge 5 to the sealing seam.

Die Folienverpackung 1 ist aus einem mehrlagigen Verbund aufgebaut, wobei eine der Lagen aus einer spleißfähigen Kunststoffolie besteht, in welcher der Einschnitt 6 bzw. 16 vorgesehen ist. Die anderen Lagen weisen dagegen diesen Einschnitt nicht auf.The film packaging 1 is constructed from a multilayer composite, one of the layers consisting of a splicable plastic film in which the incision 6 or 16 is provided. The other layers, however, do not have this incision.
