Die Erfindung geht aus von einem Verpackungsbehälter nach der Gattung des Hauptanspruchs. Es ist durch die DE-OS 25 37 3^7 ein solcher Verpackungsbehälter bekannt, bei dem, um ein Platzen des dichten Behälters zu vermeiden, vom Füllgut, beispielsweise Kaffee, abgegebenes Gas durch eine oder mehrere öffnungen in der Wand des Behälters und durch das diese abdeckende Überdruckventil entweichen kann. Da solche Ventile sehr staubempfindlich sind und durch in dem entweichenden Gas mitgeführte Füllgutteilchen in ihrer Funktion beeinträchtigt werden, können, ist der Durchlaß bei dem bekannten Behälter in Form mehrerer Löcher mit geringem Querschnitt ausgebildet oder mit ei-The invention is based on a packaging container according to the preamble of the main claim. It's through the DE-OS 25 37 3 ^ 7 such a packaging container known at to prevent the tight container from bursting through the gas given off by the product, for example coffee one or more openings in the wall of the container and through the overpressure valve covering them escape can. Since such valves are very sensitive to dust and due to the product particles carried along in the escaping gas can be impaired in their function, the passage in the known container is in the form of several Holes formed with a small cross-section or with a

nem Filterpapierstück abgedeckt. Das Herstellen von Löchern in der Behälterwand mit einer Weite von etwa 0,05 mm, wie beispielsweise bei gemahlenem Kaffee erforderlich, ist beim Herstellen der Verpackungsbehälter auf einfache Weise und mit einfachen Mitteln kaum möglich. Auch das Abdecken der Durchlaßöffnung mit einem Filterpapierstück birgt Schwierigkeiten in sich.Covered with a piece of filter paper. Making holes in the container wall with a width of about 0.05 mm, as required, for example, for ground coffee, is required when manufacturing the packaging container hardly possible in a simple way and with simple means. Also covering the passage opening with a piece of filter paper poses difficulties.

Vorteile der ErfindungAdvantages of the invention

Der erfindungsgemäße Verpackungsbehälter mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß der Schlitz mit einem einfachen, an seiner Stirnseite abgeschrägten zylindrischen Stempel geschnitten werden kann. Besonders vorteilhaft wirkt sich dazu aus, daß die durch den Schlitz begrenzte Klappe in die Ebene der Behälterwand zurückfedert oder zurückgedrückt werden kann, so daß die Breite des Schlitzes kleiner ist als 0,05 mm, wobei durch die Länge des Schlitzes aber ein genügend großer Durchgangsquerschnitt für entweichendes Gas gegeben ist. Dadurch ist die Strömungsgeschwindigkeit des Gases gering und die Filterwirkung sehr hoch.The packaging container according to the invention with the characterizing features of the main claim has on the other hand the advantage that the slot with a simple, beveled cylindrical punch on its end face can be cut. It is particularly advantageous that the flap delimited by the slot can be resilient or pushed back into the plane of the container wall, so that the width of the slot is smaller than 0.05 mm, with a sufficiently large passage cross-section due to the length of the slot is given for escaping gas. As a result, the flow rate of the gas is low and the filter effect is low very high.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Hauptanspruch angegebenen Verpackungsbehälters möglich. Besonders vorteilhaft ist die Ausbildung des Schlitzes als Halbkreisbogen, da bei dieser form, die Rückfederung des Schnittbereichs am größten ist.By the measures listed in the subclaims are advantageous developments and improvements of the packaging container specified in the main claim possible. The formation of the slot as a semicircular arc is particularly advantageous, since in this form, the Springback of the cutting area is greatest.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Fig. 1 eine Beutelpackung in schaubildlicher Barstellung und Fig. 2 einen !Teil der Wandung der Beutelpackung mit einem überdruckventil im Querschnitt in der Ebene II-II der Fig. 1 in vergrößertem Maßstab.An embodiment of the invention is shown in the drawing and in the following description explained in more detail. 1 shows a pouch pack in a diagrammatic representation and FIG. 2 shows a part the wall of the bag pack with a pressure relief valve in cross section in the plane II-II of FIG. 1 in enlarged scale.

Ein Beutel 1 aus einem flexiblen Packstoff enthält ein gasabgebendes Gut, beispielsweise gemahlenen Kaffee. Um ein Bombieren des dicht verschlossenen Beutels 1 zu verhindern, hat dieser in seiner vorderen Wand 2 eine Öffnung 3» die von einem aufgeklebten Überdruckventil 5 verschlossen ist. Das Überdruckventil 5 besteht aus einer starren Grundplatte 6 mit einer LochungA bag 1 made of a flexible packaging material contains a gas-emitting material, for example ground coffee. In order to prevent the tightly closed bag 1 from buckling, it has 2 in its front wall an opening 3 »that of a glued-on pressure relief valve 5 is closed. The pressure relief valve 5 consists of a rigid base plate 6 with a perforation

Bei entstehendem Überdruck im Beutel 1 entweicht das Gas durch die Öffnung 3 in die Lochung 7 des Überdruckventils 5 und von dort durch die Ventilkanäle 9 ins Freie. Im Ruhezustand preßt der atmosphärische Luftdruck die Membrane 8 auf die Grundplatte 6, so daß die Ventilkanäle 9 geschlossen sind und so das Eindringen von Außenluft in den Beutel 1 verhindern.in alignment with the opening 3 in the wall 2 and out a flexible membrane 8, which valve channels 9 are partially glued to the base plate 6 is. If overpressure occurs in the bag 1, the gas escapes through the opening 3 into the perforation 7 of the overpressure valve 5 and from there through the valve channels 9 to the outside. In the idle state the atmospheric presses Air pressure the membrane 8 on the base plate 6, so that the valve channels 9 are closed and so that Prevent outside air from entering the bag 1.

Die Öffnung 3 in der Wand 2 des Beutels 1 hat die ?orm eines bogenförmigen Schlitzes 10, dessen Spaltbreite kleiner als 0,05 mm ist. Vorzugsweise hat der Schlitz 10 die Form eines Halbkreises mit einem Radius von 1 bis 2 mm. Der Schlitz 10 wird in die Wand 2 des Beutels mit einem zylindrischen Stempel mit angeschrägter Stirnseite eingeschnitten. Der dabei aus der Ebene der Wand 2 herausgebogene Halbkreisbereich federt durch die Rückstellkraft des Fackstoffes in die ursprüngliche Lage zurück, bzw. wird mit Andrückmitteln in die Ebene der Wand 2 zurückgedrückt.
