This invention concerns a device for receiving tubular packaging films, with a tubular base (1) in conical form which has at its one axial end (3) an external diameter (d) which is less than the diameter (F) of the packaging film (2) to be received, such that the packaging film (2) can be pushed from this end (3) over the base (1) in folded form. At its other axial end (4), the base (1) has an external diameter (D) which is larger than the diameter (F) of the packaging film (2), so that a packaging film (2) pushed onto the base (1) cannot slide over this end (4), but by means of an operator can be pulled off the base (1) by stretching the packaging film over the end (4) and can be filled through the base (1).

Description

Beschreibung:Description:
Vorrichtung zur Aufnahme von schlauchförmigen VerpackungsfolienDevice for holding tubular packaging films
Die Erfindung betrifft eine Vorrichtung zur Aufnahme von schlauchförmigen Verpackungsfolien. Des weiteren betrifft die Erfindung ein Verfahren zum Verpacken von Gefriergut, zu entsorgendem Gut und dergleichen in Schlauchfolien sowie ein Schweißgerät zur Durchführung des Verfahrens.The invention relates to a device for receiving tubular packaging films. Furthermore, the invention relates to a method for packaging frozen goods, goods to be disposed of and the like in tubular films and a welding device for carrying out the method.
Schlauchförmige Verpackungsfolien werden im Haushaltsbereich beispielsweise zum Verpacken von Gefriergut verwendet, wobei sie jeweils in der gewünschten Länge von dem Folienschlauch abgeschnitten und an beiden Enden mit einem Folienschweißgerät verschlossen werden. Im Handel sind solche Folienschläuche hauptsächlich in flach gewickelter Form erhältlich. Weiterhin sind auch Verpackungsschläuche bekannt, die nach dem sog. Kondomprinzip zu einem Ringwulεt aufgewickelt sind, der je nach Bedarf abgewickelt wird.Tubular packaging films are used in the household sector, for example, for packaging frozen goods, each being cut off from the film tube in the desired length and sealed at both ends with a film sealing device. Such film tubes are commercially available mainly in flat-wound form. Furthermore, packaging tubes are also known, which are wound up according to the so-called condom principle to form an annular bead, which is unwound as required.
Die Handhabung der so bereitgestellten Verpackungsβchläuche wird häufig als umständlich empfunden, da die Folie vor dem Verschweißen abgeschnitten werden muß, wodurch häufig mehr Material als erforderlich verwendet wird, und auch das Einlegen des Gefrierguts in den nach Schließen eines offenen Endes gebildeten Beutel oftmals schwierig ist, weil insbesondere bei sperrigem Gefriergut der Beutel auf umständliche Weise von Hand offengehalten werden muß.The handling of the packaging tubes provided in this way is often perceived as cumbersome, since the film has to be cut off before sealing, which means that more material is often used than is necessary, and it is also often difficult to insert the frozen goods into the bags formed after the open end has been closed, because the bag has to be kept open by hand in a cumbersome way, especially with bulky frozen goods.
Aufgabe der Erfindung ist es demnach, eine Vorrichtung zur Aufnahme von schlauchförmigen Verpackungsfolien zu schaffen, wel-It is therefore an object of the invention to provide a device for receiving tubular packaging films, which
BES IGUNGSKOPIE ehe es ermöglicht, die Verpackungsfolien in handhabungsgerechter Form bereitzustellen und es insbesondere ermöglicht, das zu verpackende Gut auf einfache Weise in die Verpackungsfolie einzubringen.BEST COPY before it makes it possible to provide the packaging films in a form suitable for handling and, in particular, enables the goods to be packaged to be introduced into the packaging film in a simple manner.
Diese Aufgabe ist erfindungsgemäß durch eine Vorrichtung zur Aufnahme von schlauchförmigen Verpackungsfolien gelöst, die gekennzeichnet ist durch einen rohrförmigen Grundkörper mit Konusform, der an seinem einen axialen Ende einen Außendurchmesser hat, der geringer als der Durchmesser der aufzunehmenden Verpackungs olien ist, so daß die Verpakkungsfolie in geraffter Form von diesem Ende her über den Grundkörper geschoben werden kann, und der an seinem anderen axialen Ende einen Außendurchmesser hat, der so viel größer als der Durchmesser der Verpackungsfolien ist, daß eine auf den Grundkörper aufgeschobene Verpackungsfolie nicht über dieses Ende rutschen, aber durch eine Bedienungsperson über das Ende vom Grundkörper abgezogen werden kann und durch den Grundkörper be- füllbar ist.This object is achieved by a device for receiving tubular packaging films, which is characterized by a tubular base body with a conical shape, which has at its one axial end an outer diameter which is less than the diameter of the packaging to be accommodated, so that the packaging film in ruched form can be pushed from this end over the base body, and which has at its other axial end an outer diameter which is so much larger than the diameter of the packaging films that a packaging film pushed onto the base body does not slip over this end, but through an operator can be pulled off the base body via the end and can be filled through the base body.
Erfindungsgemäß wird somit die schlauchförmige Verpackungsfolie in geraffter Form auf den Grundkörper der Vorrichtung aufgelegt und kann von diesem über den größeren Rand gegen den Widerstand des Grundkörpers abgezogen werden. Nachdem das untere, vom Grundkörper abgezogene Ende des Verpackungsεchlauchs durch beispielsweise Verschweißung oder Heißsiegelung verschlossen worden ist, kann der so gebildete Beutel in einfacher Weise durch den Grundkörper befüllt werden, ohne daß es erforderlich ist, den Beutel auf umständliche Weise von Hand offenzuhalten.According to the invention, the tubular packaging film is thus placed in a gathered form on the base body of the device and can be removed from it over the larger edge against the resistance of the base body. After the lower end of the packaging tube which has been pulled off the base body has been closed by, for example, welding or heat sealing, the bag thus formed can be filled through the base body in a simple manner without it being necessary to keep the bag open in a laborious manner by hand.
In weiterer Ausbildung der Erfindung ist vorgesehen, daß der Grundkörper zumindest an seinem axialen Ende großen Außendurchmessers so elastisch nachgiebig ausgebildet ist, daß der Grundkörper in diesem Endbereich zum Verschweißen eines vom Grundkörper abgezogenen Folienabschnitts zusammengedrückt werden kann. Damit wird die Möglichkeit eröffnet, das offene Ende eines befüllten Folienabschnitts sauber zu verschweißen, da beim Zusammendrücken des Grundkörpers sich auch das Folienmaterial exakt aufeinanderlegt. Damit kann das Verschließen vor dem Abtrennen des gefüllten Folienabschnitts erfolgen, so daß der Verschnitt sehr gering gehalten werden kann.In a further embodiment of the invention it is provided that the base body is designed so resiliently at least at its axial end of a large outer diameter that the base body is compressed in this end region for welding a film section pulled off the base body can be. This opens up the possibility of welding the open end of a filled section of film cleanly, since when the base body is compressed, the film material also lies exactly on top of one another. The closure can thus take place before the filled film section is cut off, so that the waste can be kept very low.
Besonders ist es dabei günstig, wenn der Rand des Grundkörpers am axialen Ende großen Durchmessers so ausgebildet ist, daß sich der Rand beim Zusammendrücken des Grundkörpers unter Bildung einer geraden Linie flach aufeinanderlegt.It is particularly advantageous if the edge of the base body is formed at the axial end of a large diameter so that the edge lies flat on one another when the base body is pressed together, forming a straight line.
In Ausbildung der Erfindung ist weiterhin vorgesehen, daß ein Deckel lösbar am Grundkörper angebracht ist, der die Außenfläche des Grundkörpers zumindest in dem Pereich, der die geraffte Verpackungsfolie trägt, *.-jdeckt. Hierdurch wird auch bei längerer Aufbewahrung eine weitreichende Hygiene erzielt, da dip Schlauchfolie gegen Verschmutzung geschützt ist. Der Dackel kann beispielsweise so ausgebildet sein, daß er das axiale Ende kleinen Durchmessers des Grundkörpers umgreift und mit einem Ringsteg in den Grundkörper eingreift, wo er zweckmäßigerweise mit der Innenfläche des Grundkörpers verschraubt ist.In an embodiment of the invention it is further provided that a cover is detachably attached to the base body, which covers the outer surface of the base body at least in the area that carries the gathered packaging film *. As a result, extensive hygiene is achieved even when stored for a long time, since dip tubular film is protected against contamination. The dachshund can, for example, be designed so that it engages around the axial end of the small diameter of the base body and engages with an annular web in the base body, where it is expediently screwed to the inner surface of the base body.
An dem Deckel kann eine Halterung zur Anbringung der Vorrichtung beispielsweise an einer Schrankwand vorgesehen sein. Außerdem kann an dem Deckel ein Tragegriff oder Henkel angebracht sein, um die Vorrichtung mit einem befüllten Beutel auf einfache Weise zu transportieren.A holder for attaching the device to a cabinet wall, for example, can be provided on the cover. In addition, a handle or handle can be attached to the lid in order to transport the device with a filled bag in a simple manner.
Die erfindungsgemäße Vorrichtung kann Teil eines Verpackungsgerät zum Verpacken von Gefriergut, zu entsorgendem Gut wie Haushaltsmüll oder dergleichen sein. In diesem Fall ist der Grundkörper zweckmäßiger Weise oberhalb einer Schweiß- oder Heißsiegeleinrichtung vorgesehen, so daß die Schlauchfolie nach unten von dem Grundkörper abgezogen und an Unter- bzw. Oberseite verschlossen werden kann.The device according to the invention can be part of a packaging device for packaging frozen goods, goods to be disposed of such as household waste or the like. In this case, the base body is expediently provided above a welding or heat sealing device, so that the tubular film is at the bottom can be removed from the base body and closed at the bottom or top.
Hinsichtlich vorteilhafter Ausgestaltungen der Erfindung wird auf die Unteransprüche sowie die nachfolgende Erläuterung anhand der Zeichnung verwiesen, in der die einzige Figur eine Ausführungsform einer erfindungsgemäßen Vorrichtung zur Aufnahme von schlauchförmigen Verpackungsfolien in perspektivischer Ansicht zeigt.With regard to advantageous embodiments of the invention, reference is made to the subclaims and the following explanation with reference to the drawing, in which the single figure shows an embodiment of a device according to the invention for receiving tubular packaging films in a perspective view.
Zu der Vorrichtung gehört ein im wesentlichen rohrartig ausgebildeter Grundkörper 1 mit Konusform aus Kunststoff, der an seiner offenen Oberseite einen kleineren Außendurchmesser d hat als an seiner Unterseite. Der kleinere Außendurchmesser d am oberen Ende 3 des Grundkörpers 1 ist dabei so gewählt, daß eine Verpackungsfolie 2 in geraffter Form vom oberen Ende 3 her über den Grundkörper 1 geschoben werden kann, und der größere Außendurchmesser D am unteren Ende 4 des Grundkörpers 1 ist um so viel größer als der Durchmesser F der Verpackungsfolie 2 gewählt, daß die Verpackungsfolie 2 nicht nach unten über das Ende 4 rutschen kann, aber durch eine Bedienungsperson über das Ende 4 von dem Grundkörper 1 abgezogen werden kann .The device includes an essentially tubular base body 1 with a conical shape made of plastic, which has a smaller outer diameter d on its open upper side than on its underside. The smaller outer diameter d at the upper end 3 of the base body 1 is selected such that a packaging film 2 can be pushed in a gathered form from the upper end 3 over the base body 1, and the larger outer diameter D at the lower end 4 of the base body 1 is around chosen so much larger than the diameter F of the packaging film 2 that the packaging film 2 cannot slide down over the end 4, but can be pulled off from the base body 1 by an operator via the end 4.
Um die Verpackungsfolie 2 vor Verschmutzungen zu schützen, ist ein Deckel 6 aus festem Kunststoff vorgesehen, der auf das obere Ende 3 des Grundkörpers 1 aufgesetzt ist und mit einem Ringsteg 8 in den Grundkörper 1 eingreift. Der Ringsteg 8 weist außenseitig ein Gewinde 9 auf, das mit einem entsprechenden Innengewinde 11 an der Innenfläche 10 des Grundkörpers 1 verschraubt ist, so daß der Deckel 6 sicher an dem Grundkörper 1 gehalten ist.In order to protect the packaging film 2 from dirt, a lid 6 made of solid plastic is provided, which is placed on the upper end 3 of the base body 1 and engages with an annular web 8 in the base body 1. The annular web 8 has a thread 9 on the outside, which is screwed to a corresponding internal thread 11 on the inner surface 10 of the base body 1, so that the cover 6 is held securely on the base body 1.
An der Oberseite des Deckels 6 ist eine hakenförmige Halterung 12 vorgesehen, um die Vorrichtung an einer Wand o. dgl. anbringen zu können. Desweiteren ist an dem Deckel 6 ein Henkel 13 vorgesehen, um die Vorrichtung transportieren zu können.A hook-shaped holder 12 is provided on the top of the cover 6 in order to be able to attach the device to a wall or the like. Furthermore, there is a handle 13 on the cover 6 provided to be able to transport the device.
Die Vorrichtung kann Teil eines Verpackungsgerät zum Verpacken von Gefriergut, zu entsorgendem Gut wie Haushaltsmüll oder dergleichen sein. In diesem Fall ist der Grundkörper zweckmäßiger Weise oberhalb einer Schweiß- oder HeißBlegeleinrichtung vorgesehen, so daß die Schlauchfolie nach unten von dem Grundkörper abgezogen und an Unter- bzw. Oberseite verschlossen werden kann. Im Betrieb wird dann die Verpackungsfolie 2, welche in geraffter Form auf den Grundkörper 1 geschoben ist, von dem Grundkörper 1 nach unten hin gegen den Widerstand des Grundkörpers 1 über den größeren Außendurchmesser D vom Grundkörper 1 abgezogen. Anschließend wird das untere Ende der Verpackungsfolie 2 verschweißt, um einen Beutel zu bilden. Dieser Beutel kann dann von dem oberen Ende des Grundkörpers 1 her mit Gefriergut, Müll o. dgl. befüllt werden, ohne daß er von Hand aufgehalten werden muß. Nach dem Befüllen wird die Verpackungsfolie 2 so weit wie erforderlich von dem Grundkörper 1 nach unten abgezogen und der befüllte Verpackungsabschnitt von dem Rest der Verpackungsfolie 2 getrennt und ggf. unter Vakuum verschlossen.The device can be part of a packaging device for packaging frozen goods, goods to be disposed of such as household waste or the like. In this case, the base body is expediently provided above a welding or hot ironing device, so that the tubular film can be pulled down from the base body and closed at the bottom or top. In operation, the packaging film 2, which is pushed onto the base body 1 in a gathered form, is then pulled down from the base body 1 against the resistance of the base body 1 over the larger outer diameter D from the base body 1. The lower end of the packaging film 2 is then sealed to form a bag. This bag can then be filled with frozen goods, garbage or the like from the upper end of the base body 1 without having to be stopped by hand. After filling, the packaging film 2 is pulled down as far as necessary from the base body 1 and the filled packaging section is separated from the rest of the packaging film 2 and, if necessary, closed under vacuum.
In dem vorliegenden Ausführungsbeispiel ist das untere axiale Ende 4 des Grundkörpers 1 so elastisch nachgiebig ausgebildet und der untere Rand 5 des Grundkörpers 1 so geformt, daß der Grundkörper 1 zusammengedrückt werden kann und sich der Rand 5 dabei unter Bildung einer geraden Linie flach aufeinanderlegt. Hierdurch wird erreicht, daß sich auch die Verpackungsfolie 2 flach aufeinanderlegt, so daß der gefüllte Folienabschnitt durch die zwei Schweißbacken eines herkömmlichen Folienschweiß- geräts sauber zugeschweißt werden kann, während er noch am Rest der Verpackungsfolie hängt.In the present exemplary embodiment, the lower axial end 4 of the base body 1 is designed to be resilient and the lower edge 5 of the base body 1 is shaped such that the base body 1 can be pressed together and the edge 5 lies flat on one another to form a straight line. This ensures that the packaging film 2 also lies flat on top of one another, so that the filled film section can be welded cleanly by the two welding jaws of a conventional film welding device while it is still attached to the rest of the packaging film.
Die Schweißeinrichtung weist in bevorzugter Weise zwei Schweißeinheiten auf, durch die an dem Folienbehältnis im wesentlichen parallel zueinander liegende Schweißnähte herstellbar sind. Beim Zuschweißen des Behältnisses wird dann zunächst eine erste Schweißnaht hergestellt, um das Behältnis zu verschließen, und dann wird in den verschlossenen Beutel wenigsten eine Öffnung eingebracht, durch die in dem Beutel ein Vakuum gezogen wird, und dann wird eine zweite Schweißnaht hergestellt, um den evakuierten Beutel so zu verschließen, daß durch die Öffnung keine Luft mehr in den Beutel eindringen kann. The welding device preferably has two welding units by means of which weld seams lying essentially parallel to one another can be produced on the film container are. When the container is sealed, a first weld is then first made to close the container, and then at least one opening is made in the closed bag through which a vacuum is drawn in the bag, and then a second weld is made around the to seal the evacuated bag in such a way that no air can enter the bag through the opening.
