Description

Verfahren zum Herstellen sauerstoffarmer Verpackungen Die Erfindung betrifft ein Verfahren zum Herstellen sauerstoffarmer Verpackungen, bei dem in das zu verpackende Gut ein Spülgas entwickelndes oder abgebendes Mittel in die verschließbaren Verpackungsbehälter eingegeben wird.Method of making low-oxygen packages The invention relates to a process for the production of low-oxygen packaging, in which the Goods to be packaged a purge gas developing or releasing agent in the closable Packaging container is entered.

Es ist bereits bekannt, in Verpackungsbeutel zuunterst Trockeneis oder einen anderen in Gas übergehenden Stoff einzufüllen, die Einfüllöffnungen der Beutel bis auf einen Restquerschnitt zu verschließen, eine gewisse Zeit lang zu warten und dann den Restquerschnitt der oeffnung vollends zu verschließen. Das sich bildende Gas erzeugt im Beutel in Richtung des zunachst noch offen gebliebenen Restquerschnitts eine Spülströmung, derart, daß im Beutel entnaltender Sauerstoff weitgehend herausgetrieben wird.It is already known to put dry ice at the bottom in packaging bags or to fill another substance passing into gas, the filler openings of the To close the bag except for a residual cross-section for a certain period of time wait and then completely close the remaining cross-section of the opening. That I Forming gas is generated in the bag in the direction of the remaining cross-section that was initially still open a flushing flow, such that oxygen contained in the bag is largely driven out.

Nachteilig für die maschinelle Durchfünrung dieses Verfahrens ist, daß eine Speicherstrecke zwischen Vorverschließwerkzeuger, und Endverschließerkeugen vorgesenen werden mu. Da der technische Erfolg des Verfahrens von der geeigneten Wartezeit zwischen Füllvorgang und endgültigem Verschließen entscheidend abhängig ist, diese Wartezeit aber wegen wechselnder Gutbeschaffenheit und Temperatur ständig verändert werden muß, müßte die Länge dieser Speicherstrecke den unterschiedlichen Wartezeiten anpaßbar sein. Dies ist jedoch nicnt ohne groben tecnnischen Aufwand möglicn.The disadvantage for the machine implementation of this process is that that a storage section between the pre-closing tool and the end-closing device must be presented. Because the technical success of the process of the appropriate The waiting time between the filling process and the final closing is crucially dependent is, but this waiting time is constant due to changing properties and temperature must be changed, the length of this storage path would have to be different Waiting times can be adjusted. However, this is not possible without a great deal of technical effort possible.

Um die genannten Nacnteile zu vermeiden, wird gemEB der Erfindung ein verbessertes Verfahren vorgeschlagen, wel.According to the invention, in order to avoid the mentioned negative parts proposed an improved method wel.

ches dadurch gekennzeichnet ist, daß es unter Verwendung von Verpackungsbehältern durchgeführt wird, die mit unter innerem Überdruck öffnenden Ventilen versenen sind.ches is characterized in that it is made using packaging containers carried out, which are provided with valves that open under internal overpressure.

Die mit solcnen Ventilen versenenen Verpackungsbehälter können unmittelbar nacn dem Füllen verschlossen werden.The packaging containers sunk with such valves can immediately be closed after filling.

Die Einhaltung einer bestimmßten, jedocn einer ständigen Änderung unterliegenden Wartezeit entf-llt dadurcn. Die Maschine zur Durchführung des Verfahrens erfordert weniger technischen Aufwand und Bauraum.Compliance with a certain, but constant change The waiting time underlying this does not apply. The machine to carry out the procedure requires less technical effort and installation space.

Das erfindungsgemäße Verfahren ist nachfolgend anhand einer einen Verpackungsbehälter darstellenden Zeichnung näher erläutert.The inventive method is based on a one Packaging container illustrative drawing explained in more detail.

Der Verpackungsbehälter 1 ist beispielsweise inform eines gasdichten 3eutels ausgebildet, in dessen Wandung 2 ein unter innerem Überdruck öffnendes Ventil 5 eingearbeitet ist. Das Ventil 3, das in beliebiger Weise ausgebildet sein kann, ist vorzugsweise am Halsteil 4 des Beutels 1 angeardnet.The packaging container 1 is, for example, in the form of a gas-tight one 3bag formed, in the wall 2 of a valve that opens under internal overpressure 5 is incorporated. The valve 3, which can be designed in any way, is preferably attached to the neck part 4 of the bag 1.

Die Durcrifünrung des Verfahrens geschieht in der Weise, daß zuerst Trockeneis 5 oder dergleichen und dann das zu verpackende Gut rg in den Ventilbeutel 15 eingefüllt wird.The procedure is carried out in such a way that first Dry ice 5 or the like and then the goods to be packaged rg in the valve bag 15 is filled.

Ansenlie3end wird der Beutel 1 gasdicht verschlossen, was beispielsweise durch Flachpressen und Erwärmen des Halsteils 4 geschehen kann. Das nach dem Verschließen noch vorhandene Trockeneis 5 sublimiert und erzeugt im Beutel 1 einen Druckanstieg, derart, daß das Ventil 5 öffnet und das aus dem Trockeneis 5 entstehende Gas 7 nach Durchströmen des Guts 6 durch das Ventil 3 entweicht. Bei diesem Vorgang wird der im Gut enthaltene Sauerstoff ausgespült.The bag 1 is then closed in a gas-tight manner, for example can be done by pressing flat and heating the neck part 4. That after closing remaining dry ice 5 sublimates and creates a pressure increase in bag 1, in such a way that the valve 5 opens and the gas 7 formed from the dry ice 5 follows Flow through the material 6 escapes through the valve 3. During this process, the The oxygen contained in the good is flushed out.

Wenn die Gasentwicklung beendet ist, schließt das Ventil 5 selbsttNti5, sodaß der Wiedereintritt von Sauerstoff aus der Umgebung vernindert wird.When the evolution of gas has ended, the valve 5 closes automatically, so that the re-entry of oxygen from the environment is reduced.
