Description

Die vorliegende Erfindung betrifft einen stehfähigen Beutel.The present invention relates to a standing pouch.

Die EP-A-364 373 (Dokument gemäss Art. 54(3)) offenbart stehfähige Beutel, deren durch Sicken gebildeter Ausgiesskanal durch Schweissnähte bestimmt wird, die rechtwinklig oder auch längs zur Achse des Ausgangskanals liegend angeordnet sind.EP-A-364 373 (document according to Art. 54 (3)) discloses standing bags, the pouring channel formed by beads is determined by weld seams which are arranged at right angles or along the axis of the outlet channel.

Als nachteilig erweist sich bei der ersten Lösung nach Figur 1, dass

  • durch die den Beutelinhalt zurückhaltende schmale Naht vom Beutelinnenraum ein Abschnitt abgetrennt wird, in welchen der Beutelinhalt eindringen kann, der beim Oeffnen des Beutels entlang der Schnittkante unkontrolliert ausläuft, und
  • beim unsachgemässen Oeffnen des Beutels die den Beutelinhalt zurückhaltende Naht zerstört wird, so dass der Beutelinhalt ebenfalls unkontrolliert ausläuft.
The first solution according to FIG. 1 has the disadvantage that
  • by the narrow seam retaining the bag contents, a section is separated from the bag interior into which the bag contents can penetrate, which runs out in an uncontrolled manner along the cut edge when the bag is opened, and
  • if the bag is improperly opened, the seam holding back the bag contents is destroyed, so that the bag contents also leak out in an uncontrolled manner.

Als nachteilig erweist sich bei der zweiten Lösung nach Figur 5, dass

  • die Schweissnähte den Ausgiesskanal nicht eng umschliessen, so dass der Beutelinhalt unkontrolliert auslaufen und auch in den Raum des abzuschneidenden Eckabschnitten eindringen kann,
  • dass die eine Schweissnaht lediglich die schmale Randnaht ist und infolge der einspringenden Kontur dieser Randnaht die Halterung des Beutels in der Abfüllmaschine erschwert ist.
The second solution according to FIG. 5 has the disadvantage that
  • the weld seams do not tightly enclose the pouring channel, so that the contents of the bag run out in an uncontrolled manner and can also penetrate into the space of the corner sections to be cut off,
  • that the one weld seam is only the narrow edge seam and, due to the protruding contour of this edge seam, it is difficult to hold the bag in the filling machine.

Ziel der Erfindung ist es, unter Vermeidung der Nachteile des Standes der Technik, einen stehfähigen Beutel so zu verbessern, dass dieser sicher und zuverlässig entleert werden kann und wobei die Lage und Form des Ausgiesskanals verändert werden kann, ohne dass aufwendige Veränderungen des KonturenstanzwerkzeugeS notwendig sind.The aim of the invention is, while avoiding the disadvantages of the prior art, to improve a standing bag so that it can be emptied safely and reliably and the position and shape of the pouring channel can be changed without complex changes to the contour punching tool are necessary.

Dieses Ziel wird erfindungsgemäss mit einem Beutel gemäss dem Anspruch 1 erreicht.This goal is achieved according to the invention with a bag according to claim 1.

Ein solcher Beutel behält auch im Bereich der Ausgiessöffnung seine vollständige eckige Grundform. Die Halterung des Beutels mittels Klammern in der Abfüllmaschine ist damit einfacher. Die Verbindung der beiden Seitenwänden erstreckt sich vollständig über die voll ausgebildete Ecke und schliesst sich eng an den Ausgiesskanal an. Unabhängig von Form und Lage des Kanals sind somit immer gleiche Verhältnisse gegeben. Der Beutelinhalt kann nicht unkontrolliert ausfliessen und es sind keine Räume im abzuschneidenden Eckabschnitt vorhanden, in welche der Behälterinhalt hineinfliessen kann. Die Lage und Form des Ausgiesskanals kann beliebig verändert werden, ohne dass eine aufwendige Anpassung des Konturenstanzwerkes notwendig ist.Such a bag also retains its complete angular basic shape in the area of the pouring opening. It is easier to hold the bag in the filling machine using clips. The connection of the two side walls extends completely over the fully formed corner and closely adjoins the pouring channel. Regardless of the shape and position of the channel, the conditions are always the same. The contents of the bag cannot flow out in an uncontrolled manner and there are no spaces in the corner section to be cut into which the contents of the container can flow. The position and shape of the pouring channel can be changed as required, without the need for time-consuming adaptation of the contour punching unit.

Ferner kann zum Wiederverschliessen des Klebbeutels ein Klebstreifen an einer Seitenwand angebracht werden und die voll verschweisste Ecke auf diesen Klebstreifen umgelegt werden, wobei infolge der beidseitig an den Ausgiesskanal anschliessenden flächig miteinander verbundenen Seitenwände, ein sicheres Verschliessen des Kanals gewährleistet ist.Furthermore, for reclosing the adhesive bag, an adhesive strip can be attached to a side wall and the fully welded corner can be folded over onto this adhesive strip, a secure closure of the channel being ensured as a result of the side walls connected to the pouring channel on both sides.

Im folgenden wird die Erfindung anhand der beiliegenden Figuren erläutert.The invention is explained below with reference to the attached figures.

Es zeigen:

  • Figur 1 ein erstes Ausführungsbeispiel eines erfindungsgemässen Beutels,
  • Figur 2 einen Schnitt entlang der Linie II-II in Figur 1, und
  • Figur 3 ein zweites Ausführungsbeispiel des erfindungsgemässen Beutels.
Show it:
  • FIG. 1 shows a first exemplary embodiment of a bag according to the invention,
  • 2 shows a section along the line II-II in Figure 1, and
  • Figure 3 shows a second embodiment of the bag according to the invention.

Die Figur 1 zeigt eine bevorzugte Ausführungsform eines erfindungsgemässen Beutels, dessen Grundform aus einer Folie besteht, die so zugeschnitten wird, dass eine Vorder- und Rückwand 1 und 2 sowie ein Faltboden 3 entstehen, die an den offenen Rändern 4 durch Schweissen, Kleben, Heissversiegeln, usw. miteinander verbunden werden, um einen geschlossenen stehfähigen Beutel herzustellen. Der Beutel ist ferner an den Ecken im Bereich des Faltbodens 3 jeweils mit Ecknähten 4a versehen. Die Ecknähte 4a sind unter 45° über die Ecken gelegt und verbinden jeweils nur einen Faltbodenabschnitt mit dem unmittelbar gegenüberliegenden Abschnitt der Vorder- bzw. Rückwand. Dadurch bilden die Aussenfaltkanten 5,6 die Kanten auf denen der gefüllte Beutel steht.FIG. 1 shows a preferred embodiment of a bag according to the invention, the basic shape of which consists of a film which is cut in such a way that a front and rear wall 1 and 2 and a folding base 3 are formed, which are welded, glued, heat-sealed at the open edges 4 , etc. are connected together to produce a closed, standing bag. The bag is also provided with corner seams 4a at the corners in the area of the folding base 3. The corner seams 4a are placed at 45 ° over the corners and each connect only one folding floor section to the directly opposite section of the front or rear wall. As a result, the outer folding edges 5, 6 form the edges on which the filled bag stands.

Der Beutel ist mit einer Ausgiesseinrichtung 13 versehen, die im Bereich einer Ecke so eingeordnet ist, dass der Beutel durch Abtrennen eines Eckabschnittes geöffnet werden kann.The bag is provided with a pouring device 13 which is arranged in the area of a corner in such a way that the bag can be opened by severing a corner section.

Die Ausgiesseinrichtung umfasst zwei Sicken 14, die einander gegenüberliegend in den Seitenwänden 1,2 ausgebildet sind. Im Bereich der Ausgiesseinrichtung ist die Naht 4 über den Eckabschnitt erweitert, wodurch die Ausgiessöffnung bei geöffnetem Beutel lagestabil gehalten wird.The pouring device comprises two beads 14 which are formed opposite one another in the side walls 1, 2. In the area of the pouring device, the seam 4 is widened over the corner section, as a result of which the pouring opening is held in a stable position when the bag is open.

Bei dem in den Figuren 1 und 2 dargestellten Beutel ist die Ausgiesseinrichtung unter einem Winkel von 45° bezüglich der Eckränder angeordnet .Es ist aber möglich, diesen Winkel zwischen 15° und 75° zu variieren, um durch Halten des Beutels in einer Schräglage eine bestimmte Menge aus dem Beutel zu entnehmen. Hierbei kann es von Vorteil sein, wenn am Beutel eine Markierung angebracht wird.In the case of the bag shown in FIGS. 1 and 2, the pouring device is arranged at an angle of 45 ° with respect to the corner edges. However, it is possible to vary this angle between 15 ° and 75 ° in order to maintain a certain angle by holding the bag in an inclined position Take the amount out of the bag. It can be advantageous here if a marking is made on the bag.

Der in Figur 3 dargestellte Beutel ist ähnlich der Grundausführung ausgebildet und enthält wie dieser eine Vorder- und Rückwand 1,2 sowie einen Faltboden 3, die an den Rändern 4 miteinander verbunden sind.The bag shown in Figure 3 is similar to the basic design and contains like this a front and rear wall 1, 2 and a folding base 3 which are connected to one another at the edges 4.

Gegenüber der Grundausführung weist der Beutel einen Abschnitt 15 mit Tragöffnung auf, die aus fünf Löchern 16 gebildet ist. Hierzu sind am Zuschnitt des Beutels symmetrisch zur Faltlinie 17 an der gleichen Seite der Vorder- und Rückwand jeweils ein Abschnitt vorgesehen, die nach dem Falten des Zuschnittes um die Faltlinie 17 und die Aussenfaltlinie 5,6 (es ist nur eine sichtbar) übereinander liegen. Diese Abschnitte werden an den Rändern 18 miteinander verbunden.Compared to the basic design, the bag has a section 15 with a support opening, which is formed from five holes 16. For this purpose, a section is provided on the cut of the bag symmetrically to the fold line 17 on the same side of the front and rear wall, which after the cut is folded around the fold line 17 and the outer fold line 5, 6 (only one is visible). These sections are joined together at the edges 18.

Wie aus Figur 3 ersichtlich, sind die Ecknähte 4a an der Seite des Abschnittes 15 über diesen gelegt, die hier als Verstärkungsnähte 19 dienen, wie die Verstärkungsnaht 19 am anderen Ende. Durch diese Verstärkungsnähte 19 wird die Handhabung des Beutels verbessert.As can be seen from FIG. 3, the corner seams 4a are placed on the side of the section 15, which serve here as reinforcement seams 19, like the reinforcement seam 19 at the other end. The handling of the bag is improved by these reinforcing seams 19.

Um den Beutel nach dem erstmaligen Oeffnen wieder zu verschliessen, ist auf der Vorderwand 1 ein Klebstreifen 20 im Bereich der oberen Ecke angeordnet, die dem Abschnitt 15 mit der Tragöffnung gegenüberliegt. Nach dem Oeffnen des Beutels an der durch die gestrichelte Linie 21 und das Symbol einer Schere dargestellte Stelle, kann der Beutel durch Umlegen eines Vorder- und Rückwandabschnittes wieder verschlossen werden.In order to close the bag again after opening it for the first time, an adhesive strip 20 is arranged on the front wall 1 in the region of the upper corner, which is opposite section 15 with the carrying opening. After opening the bag at the point shown by the dashed line 21 and the symbol of scissors, the bag can be closed again by folding over a front and rear wall section.

Neben der in Figur 1 dargestellten Ausführungsform des Abschnittes 15 mit Tragöffnung sind noch andere Ausführungsformen möglich. So kann die Tragöffnung auch in Form von zwei Langlöcher ausgebildet werden. Die Verstärkungsnähte im Bodenbereich können auch separat gelegt werden und zwischen den Löchern können weitere Verstärkungsnähte gelegt werden, um einen stabilen Griffteil zu erhalten. in diesem Zusammenhang wird darauf hingewiesen, dass ein separates Griffteil anstelle des Abschnittes 15 mit Tragöffnung am Beutel befestigt werden kann.In addition to the embodiment of section 15 with the support opening shown in FIG. 1, other embodiments are also possible. So the support opening can also be formed in the form of two elongated holes. The reinforcement seams in the floor area can also be laid separately and further reinforcement seams can be placed between the holes in order to obtain a stable grip part. in this context, it is pointed out that a separate handle part can be attached to the bag instead of section 15 with a support opening.
