Abstract

A process is disclosed for packaging frozen goods, waste such as household garbage and the like. The goods to be packaged are placed in a foil container (2) and packaged by welding and evacuating. The process is characterised in that the foil container is closed by a first welding operation which forms a first weld to package the goods placed therein. Holes are then formed in the closed foil container, in particular by punching or burning, and the air contained in the foil container is evacuated, in particular by a vacuum pump (5) or an aspirating fan. The thus obtained vacuum space is sealed by a second welding operation which forms a second weld between the first weld and the packaged goods. Also disclosed is a vacuum-packaging apparatus for carrying out this process.

Description

Die Erfindung betrifft ein Verfahren zum Verpacken von Gefriergut, zu entsorgendem Gut wie beispielsweise Hausmüll u. dgl., bei dem das zu verpackende Gut in einem aus Folie hergestellten Folienbehältnis durch Verschweißen und Vakuumieren verpackt wird, wobei zum Verpacken des in das Folienbehältnis eingefüllten Gutes das Folienbehältnis durch einem ersten Schweißvorgang unter Bildung einer ersten Schweißnaht verschlossen wird, Löcher in das abgeschlossene Folienbehältnis eingebracht, insbesondere gestoßen oder gebrannt werden und durch diese Löcher dem Folienbehältnis durch insbesondere eine Vakuumpumpe oder ein Sauggebläse die Luft entzogen wird, und dann das Vakuum durch einen zweiten Schweißvorgang unter Bildung einer zweiten Schweißnaht, die zwischen der ersten Schweißnaht und dem Gut liegt, abgeschlossen wird (US-PS 4,044,524).The invention relates to a method for packaging frozen goods, to be disposed of such as household waste u. Like., in the the goods to be packaged in a film container made of film is packed by welding and vacuuming, whereby for packing the goods filled into the film container the film container through a first welding process with formation a first weld seam is closed, holes in the closed Foil container introduced, especially pushed or burned and through these holes the film container the air in particular by means of a vacuum pump or a suction fan is withdrawn, and then the vacuum by a second welding process forming a second weld between the first weld seam and the good is completed (US-PS 4,044,524).

Neue Gesetze und Verordnungen betreffend die Vermeidung, Verringerung, Wiederaufbereitung und Weiterverwendung von Müll setzen eine sparsame Verwendung von Verpackungsmaterial, eine Verwendung von mehrfach verwendbaren Verpackungen und insbesondere eine adäquate Sortierung der entstehenden Abfälle zum Recyclen voraus. Aus diesem Grund gibt es schon seit längerer Zeit spezielle, zentral von den Gemeinden aufgestellte Container, in die die Endverbraucher ihr Altpapier und Altglas einwerfen können.New laws and regulations regarding avoidance, reduction, Reprocessing and reuse of waste put an economical use of packaging material, a Use of reusable packaging and in particular an adequate sorting of the generated waste for recycling ahead. For this reason, it has been around for a long time Time special containers set up centrally by the municipalities, into which the end-users throw in their waste paper and glass can.

Desweiteren erfolgt in den Haushalten eine Müllsortierung, wobei im allgemeinen eine Dreifachtrennung nach Bioabfällen, Kunststoffen und sonstigen Abfällen vorgenommen wird. Diese Mülltrennung trägt zwar zur Einsparung von Wertstoffe bei, bringt jedoch Probleme hinsichtlich der sogenannten Müllhygiene mit sich. Durch die Verteilung des Mülls auf verschiedene Tonnen wird nämlich die Verweildauer des Mülls im Haushalt deutlich erhöht, da die einzelnen, verschiedenartige Abfälle enthaltenden Tonnen nur in relativ großen Zeitabständen entleert werden. Insbesondere beim Biomüll hat sich gezeigt, daß eine Aufbewahrung von Lebensmittelresten in den Biotonnen schon nach wenigen Tagen zur Verunreinigung durch Sporen, Bakterien, Maden etc. führen kann. Außerdem kann es relativ schnell zu unangenehmen Geruchsbildungen kommen.Furthermore, waste is sorted in the households, whereby generally a triple separation according to bio waste, Plastics and other waste is made. This Waste separation helps to save valuable materials, however, brings problems with so-called garbage hygiene with yourself. By distributing the garbage to different people This is because the amount of time the garbage stays in the household becomes tons significantly increased because the individual, different types of waste Containing tons emptied only at relatively large intervals become. With organic waste in particular, it has been shown that storage of food residues in the organic bins after only a few days for contamination by spores, bacteria, Maggots etc. can lead. It can also be relative unpleasant odors develop quickly.

Aus diesem Grund wird beispielsweise in der DE 39 ⊘3 28⊘ A1 vorgeschlagen, das zu entsorgende Gut unter Vakuum zu verschweißen. Hierzu ist ein Vakuumverpackungsgerät vorgesehen, das einen Behälterraum zum Aufnehmen eines offenen Beutels aufweist, der durch einen Deckel hermetisch verschließbar und durch eine Vakuumpumpe evakuierbar ist, um im Beutelinnern ein Vakuum zu ziehen. Außerdem ist eine Schweißvorrichtung vorgesehen, um den evakuierten Beutel in dem geschlossenen Behälterraum zu versiegeln.For this reason, for example, in DE 39 ⊘3 28⊘ A1 proposed to weld the material to be disposed of under vacuum. A vacuum packaging device is provided for this purpose, which has a container space for receiving an open bag, which can be hermetically sealed with a lid and can be evacuated by a vacuum pump to inside the bag Pull vacuum. A welding device is also provided, around the evacuated bag in the closed container space to seal.

Aus der Druckschrift Patent Abstracts of Japan, Vol. 18, Nr. 483 (M-1670), 8. September 1994 ist ein weiteres Vakuumverpackungsgerät bekannt. Bei diesem werden die Müllbeutel aus einer Schlauchfolie hergestellt, die in geraffter Form oberhalb einer Schweißeinrichtung außenseitig an einem zylindrischen Einfüllstutzen gehalten ist, von dem sie nach unten abgezogen werden kann, um aus ihr durch Verschweißen der offenen Unterseite einen Beutel zu bilden, der anschließend durch den Einfüllstutzen befüllbar ist. Nach dem Einfüllen des zu verpackenden Guts wird anschließend durch den Einfüllstutzen in dem Beutel ein Vakuum gezogen und der Beutel anschließend durch die Schweißeinrichtung verschlossen.From Patent Abstracts of Japan, Vol. 18, No. 483 (M-1670), September 8, 1994 is another vacuum packaging device known. With this, the garbage bags are made of a tubular film manufactured in a gathered form above a welding device held on the outside on a cylindrical filler neck from which it can be subtracted down to form a bag by welding the open underside, which can then be filled through the filler neck. After the filling of the goods to be packaged is then carried out by the A vacuum is drawn into the filler neck and then the bag sealed by the welding device.

Aufgabe der Erfindung ist es, ein Verfahren zum Verpacken von Gefriergut, zu entsorgendem Gut oder dergleichen sowie ein Vakuumverpackungsgerät zur Durchführung des Verfahrens anzugeben, die ein hygienisches Verpacken auf einfache Weise und mit wenig Platzbedarf ermöglichen. The object of the invention is to provide a method for packaging frozen goods, to be disposed of or the like as well as a vacuum packaging device to carry out the procedure specify the hygienic packaging in a simple manner and with little space requirement enable.

Diese Aufgabe ist bei einem gattungsgemäßen Verfahren erfindungsgemäß dadurch gelöst, daß die Folie in Schlauchform in geraffter Form auf einem trichterförmigen Körper bereitgestellt wird, der an seiner Oberseite einen Außendurchmesser hat, der kleiner als der Durchmesser der Schlauchfolie ist, so daß die Schlauchfolie von oben auf den Körper geschoben werden kann, und der an seinem unteren Ende einen Außendurchmesser hat, der größer ist als der Durchmesser der Schlauchfolie, so daß die Schlauchfolie nicht nach unten vom Körper rutschen kann, aber von einer Bedienungsperson nach unten gegen den Widerstand des Körpers abgezogen werden kann.This object is achieved according to the invention in a generic method in that the film in Tubular shape in a gathered form on a funnel-shaped body is provided, which has an outer diameter at its top has, which is smaller than the diameter of the tubular film, so that the tubular film is pushed onto the body from above can, and which has an outer diameter at its lower end, which is larger than the diameter of the tubular film, so that the Tubular film cannot slide down from the body, but from one operator down against body resistance can be deducted.

Wenn bei dieser Ausführungsform das untere, vom Körper abgezogene Ende der Schlauchfolie durch einen Schweißvorgang verschlossen worden ist, kann der so gebildete Beutel in einfacher Weise durch den Körper befüllt werden, ohne daß es erforderlich ist, den Beutel auf umständliche Weise von Hand offen zu halten. If, in this embodiment, the lower one peeled off the body End of the tubular film closed by a welding process has been made, the bag thus formed can be more easily Filled through the body without the need for it the bag is laboriously open by hand to keep.

Gemäß einer Weiterbildung der Erfindung kann der Körper zur Ausführung eines Schweißvorgangs an seinem unteren Ende so weit zusammengedrückt werden, daß das Folienmaterial des Folienbehältnisses flächig aufeinanderliegt. Hierdurch wird erreicht, daß das offene Ende eines befüllten Folienabschnitts sauber verschweißt werden kann, da beim Zusammendrücken des Körpers auch das Folienmaterial exakt aufeinander legt.According to a training of Invention allows the body to perform a welding operation pressed together at its lower end so far that the film material of the film container lies flat on one another. This ensures that the open end of a filled film section are welded clean can, because when compressing the body also the film material exactly on top of each other.

Die Vakuumiervorrichtung 5 besteht aus einem sich über die gesamte Breite des Folienbehältnisses 2 erstreckenden schließbaren Kanal 6, über dessen Länge eine Mehrzahl von Absaugöffnungen 7 vorgesehen sind. Die Absaugöffnungen 7 haben jeweils einen spitzen Kragen 8, der es ermöglicht, in das Folienbehältnis 2 einzudringen, um in diesem Vakuum zu ziehen. Die Kragen 8 können beheizbar sein, um Löcher in die Folie zu brennen und auf diese Weise das Einbringen der Kragen 8 in das Folienbehältnis 2 zu erleichtern.The vacuum device 5 consists of one over the entire Width of the film container 2 extending closable Channel 6, over the length of a plurality of suction openings 7 are provided. The suction openings 7 each have a pointed collar 8, which makes it possible to put it in the film container 2 penetrate to pull in this vacuum. The collar 8 can be heated to burn holes in the film and in this way the introduction of the collar 8 into the film container 2 to facilitate.

Zum Verschließen und Evakuieren eines Folienbehältnisses 2 wird zunächst die obere Schweißeinheit 3 betätigt, wodurch das Folienbehältnis 2 unter Bildung einer ersten Schweißnaht verschlossen wird. Anschließend wird die Vakuumiervorrichtung 5 betätigt und über die Absaugöffnungen 7 aus dem schließbaren Kanal 6 Luft abgesaugt, wodurch die Folie an die spitzen Kragen 8 angezogen wird, so daß diese in die Folie eindringt und im Innern des Folienbehältnisses 2 ein Vakuum erzeugt wird. For closing and evacuating a film container 2 the upper welding unit 3 is first actuated, whereby the Foil container 2 closed to form a first weld becomes. The vacuum device 5 is then actuated and via the suction openings 7 from the closable Channel 6 sucked air out, causing the film to the pointed collar 8 is tightened so that it penetrates the film and inside the Foil container 2 a vacuum is generated.

Schließlich werden die Schweißbacken 3a, 3b; 4a, 4b der Schweißeinheiten 3, 4 wieder auseinandergefahren, so daß ein neues Folienbehältnis 2 zugeführt werden kann.Finally, the welding jaws 3a, 3b; 4a, 4b the Welding units 3, 4 moved apart again, so that a new film container 2 can be supplied.

Es ist auch möglich, in an sich bekannter Weise anstelle von bereits fertigen Folienbehältnissen schlauchförmige Verpakkungsfolien 12 zu verwenden, und aus diesen die Folienbehältnisse 2 herzustellen. In diesem Fall wird zur Bereitstellung der Folienschläuche 12 bevorzugterweise eine Vorrichtung verwendet, wie sie in Figur 2 dargestellt ist. Zu der Vorrichtung gehört ein im wesentlichen trichterförmig ausgebildeter Körper 11, der an seiner offenen Oberseite einen kleineren Außendurchmesser d hat als an seiner Unterseite. Der kleinere Außendurchmesser d ist so gewählt, daß eine Verpackungsfolie 12 in geraffter Form vom oberen Ende 13 her über den Körper 11 geschoben werden kann, und der größere Außendurchmesser D am unteren Ende 14 des Körpers 11 ist um so viel größer als der Durchmesser F des Folienschlauches 12 gewählt, daß der Folienschlauch 12 nicht nach unten über das Ende 14 rutschen kann, aber durch eine Bedienungsperson unter leichter Aufdehnung über das Ende 14 vom Körper 11 abgezogen werden kann.It is also possible to use instead of Already finished film containers are tubular packaging films 12 to use, and from these the film containers 2 manufacture. In this case, it becomes available the film tubes 12 preferably use a device, as shown in Figure 2. To the device belongs to an essentially funnel-shaped body 11, which has a smaller outer diameter on its open top d has as at its bottom. The smaller outside diameter d is chosen so that a packaging film 12 in ruffled Form pushed over the body 11 from the upper end 13 can be, and the larger outer diameter D at the bottom End 14 of body 11 is so much larger than the diameter F of the film tube 12 selected that the film tube 12 can not slide down over the end 14, but through an operator with a slight stretch over the end 14 can be removed from the body 11.

Um den Folienschlauch 12 vor Verschmutzungen zu schützen, ist ein Deckel 16 vorgesehen, der auf das obere Ende 13 des Körpers 11 aufgesetzt ist und mit einem Ringsteg 18 in den Körper 11 eingreift. Der Ringsteg 18 weist außenseitig ein Gewinde 19 auf, das mit einem entsprechenden Innengewinde 21 an der Innenfläche 20 des Körpers 11 verschraubt ist, so daß der Deckel 16 sicher an dem Körper 11 gehalten ist.In order to protect the film tube 12 from contamination a lid 16 is provided on the upper end 13 of the body 11 is placed and with a ring web 18 in the body 11 engages. The ring web 18 has a thread 19 on the outside on that with a corresponding internal thread 21 on the inner surface 20 of the body 11 is screwed so that the lid 16 is held securely on the body 11.

An der Oberseite des Deckels 16 ist eine hakenförmige Halterung 22 vorgesehen, um die Vorrichtung an einer Wand o. dgl. anbringen zu können. Desweiteren ist an dem Deckel 16 ein Henkel 23 vorgesehen, um die Vorrichtung transportieren zu können.On the top of the lid 16 is a hook-shaped bracket 22 provided to the device on a wall or the like. to be able to attach. Furthermore, there is a handle on the cover 16 23 provided to be able to transport the device.

Im Betrieb wird der Folienschlauch 12, welcher in geraffter Form auf dem Körper 11 gehalten ist, von dem Körper 11 nach unten hin gegen den Widerstand des Körpers 11 über den größeren Außendurchmesser D abgezogen. Anschließend wird das untere Ende des Folienschlauches 12 verschweißt, um einen Beutel zu bilden. Dieser Beutel kann dann vom oberen Ende des Körpers 11 mit Gefriergut, Müll o. dgl. befüllt werden, ohne daß er von Hand aufgehalten werden muß. Nach dem Befüllen wird der Folienschlauch 12 so weit wie erforderlich vom Körper 11 nach unten abgezogen, um den befüllten Verpackungsabschnitt in der vorstehend beschriebenen Weise unter Vakuum zu verschliessen und vom Rest des Folienschlauches 12 zu trennen.In operation, the film tube 12, which is gathered Shape is held on the body 11 by the body 11 after below against the resistance of the body 11 over the larger one External diameter D subtracted. Then the bottom one End of the film tube 12 welded to a bag form. This bag can then from the top of the body 11th be filled with frozen goods, garbage or the like, without it from Hand must be stopped. After filling, the film tube 12 as far from body 11 as necessary subtracted to the filled packaging section in the to close in the manner described above under vacuum and separate from the rest of the film tube 12.

Dabei ist das untere Ende 14 des Körpers 11 so elastisch nachgiebig ausgebildet und insbesondere auch der untere Rand 15 des Körpers 11 so geformt, daß der Körper 11 zusammengedrückt werden kann und sich der Rand 15 dabei unter Bildung einer geraden Linie flach aufeinanderlegt. Hierdurch wird erreicht, daß sich auch die Folie flach aufeinanderlegt, so daß der gefüllte Folienabschnitt durch die Schweißbacken 3a, 3b; 4a,4b der erfindungsgemäßen Vakuumverpackungsmaschine sauber zugeschweißt werden kann, während er noch am Rest des Folienschlauches 12 hängt.The lower end 14 of the body 11 is so resilient formed and in particular also the lower edge 15 of the body 11 shaped so that the body 11 is compressed can be and the edge 15 thereby forming a straight Line laid flat on top of each other. This ensures that the film lies flat on top of one another, so that the filled one Foil section through the welding jaws 3a, 3b; 4a, 4b the vacuum packaging machine according to the invention welded clean can be while he is still on the rest of the film tube 12 hangs.
