Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Verpackung nach der Gattung des Hauptanspruchs. Durch die DE-AS 14 86 395 ist schon ein Verpackungsbehälter bekannt geworden, bei dem in der Mündung des Beutels eine aus Deckel und Rahmen bestehende Wiederverschlußeinrichtung eingesetzt ist. Derartige Wiederverschlußeinrichtungen sind jedoch zwischen Rahmen und Deckel nicht gasdicht, so daß der Behälter zum Verpacken von sauerstoffempfindlichen Gütern wie Kaffee, Milchpulver usw. nicht brauchbar ist. Es wurde deshalb vorgeschlagen, den Deckel mit einem Deckblatt zu überdecken, das auf dem Rahmen lösbar aufgesiegelt ist. Diese Anordnung ist jedoch sehr arbeitsaufwendig und gibt keine hinreichende Sicherheit für die geforderte Dichtigkeit. Ferner ist es sehr schwierig, den Rahmen der Wiederverschlußeinrichtung. gasdicht in der Beutelmündung maschinell zu befestigen. Die bekannte Packung, die an sich sehr bequem zu handhaben ist, bietet daher insgesamt gesehen keine ausreichende Sicherheit an Gasdichtigkeit, wie sie zum Verpacken hochwertiger Güter verlangt wird.The invention is based on packaging according to the type of the main claim. From DE-AS 14 86 395 a packaging container has already become known in which a reclosing device consisting of a lid and frame is inserted in the mouth of the bag. However, such reclosure devices are not gas-tight between the frame and the lid, so that the container cannot be used for packaging oxygen-sensitive goods such as coffee, milk powder, etc. It has therefore been proposed to cover the cover with a cover sheet which is releasably sealed onto the frame. However, this arrangement is very labor intensive and does not provide sufficient security for the required tightness. Furthermore, it is very difficult to reclose the frame. can be mechanically attached gas-tight in the mouth of the bag. The known pack, which is very convenient to handle in itself, therefore does not offer sufficient gas-tightness overall, as is required for packaging high-quality goods.

Es ist ferner beispielsweise durch die DE-OS 24 43 721 eine aus einem gasdichten Beutel und einem Außenbehälter mit einer WiederverschluBeinrichtung bestehende Verpackung bekannt geworden. Bei dieser Verpackung ist jedoch die WiederverschluBeinrichtung außerhalb des Beutels am AuBenbehälter angeordnet und bildet zusammen mit diesem einen Verschluß. Bei dieser Anordnung der Wiederverschlußeinrichtung ist beim Transport der Verpackung der Deckel Stößen und Drücken ausgesetzt, so daß er beschädigt werden kann. Außerdem bietet eine solche Anordnung der Wiederverschlußeinrichtung keine hohe Staubdichtigkeit der Verpackung.It is also known, for example from DE-OS 24 43 721, a packaging consisting of a gas-tight bag and an outer container with a reclosable device. With this packaging, however, the reclosure device is arranged outside the bag on the outer container and forms a closure together with the latter. With this arrangement of the reclosure device, the cover is subjected to shocks and pressures during transport of the packaging, so that it can be damaged. In addition, such an arrangement of the reclosure device does not offer a high level of dust-tightness of the packaging.

Es ist daher eine Verpackung wünschenswert, die mit Sicherheit gasdicht, deren Wiederverschlußeinrichtung in hohem Maße staubdicht ist und die eine bequeme Handhabung bietet.It is therefore desirable to have packaging which is certainly gas-tight, whose reclosing device is highly dust-tight and which is easy to handle.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Verpackung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß sie hinsichtlich Gas und Staub eine Dichtigkeit aufweist, wie sie Blechdosen bieten, daß jedoch der Energiebedarf zu ihrer Herstellung wesentlich geringer ist. Ferner besteht beim Öffnen des Beutels keine Gefahr, daß das Produkt verschüttet wird.The packaging according to the invention with the characterizing features of the main claim has the advantage that it has a tightness with respect to gas and dust, such as that offered by tin cans, but that the energy requirement for their manufacture is significantly lower. Furthermore, when the bag is opened, there is no danger that the product will spill.

Auch haftet an dem Teil des Beutels, der entfernt wird, kein Gut an, da dieser nicht in Kontakt mit dem Füllgut ist.Also, no good adheres to the part of the bag that is removed, since it is not in contact with the contents.

Die Handhabung der erfindungsgemäßen Verpackung, insbesondere das erstmalige Öffnen des Beutels wird dem Benutzer dadurch bequem gemacht, daß oberhalb der Befestigungslinie der Wiederverschlußeinrichtung ein Aufreißband am Beutel angeordnet ist. Mit dieser Ausgestaltung der erfindungsgemäßen Verpackung erübrigt sich zum erstmaligen Öffnen ein Hilfswerkzeug, wie Messer.The handling of the packaging according to the invention, in particular the opening of the bag for the first time, is made comfortable for the user in that a tear tape is arranged on the bag above the fastening line of the reclosing device. With this configuration of the packaging according to the invention, an auxiliary tool, such as a knife, is unnecessary for the first opening.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Verpackung möglich.The measures listed in the subclaims allow advantageous developments and improvements to the packaging specified in the main claim.

Beschreibung der ErfindungDescription of the invention

Die dargestellte Packung hat die Form eines Quaders und besteht im wesentlichen aus einem das Gut aufnehmenden Beutel 21, einem den Beutel 21 umgebenden Außenbehälter 22 und einer Wiederverschlußeinrichtung 23. Der Beutel 21 ist aus einem insbesondere gas- und feuchtigkeitsdichten Packstoff durch Falten und Schweißen hergestellt, z. B. aus einem Mehrschichtmaterial wie Papier/Polyäthylen, Polyester/Aluminium/Polyäthylen oder dgl., wobei die Polyäthylenschicht innen liegt und heißsiegelbar ist.The pack shown has the shape of a cuboid and essentially consists of a bag 21 which holds the goods, an outer container 22 surrounding the bag 21 and a reclosing device 23. The bag 21 is produced from a gas and moisture-tight packaging material in particular by folding and welding, e.g. B. from a multi-layer material such as paper / polyethylene, polyester / aluminum / polyethylene or the like., The polyethylene layer is inside and is heat-sealable.

Die im Beutel 21 angeordnete Wiederverschlußeinrichtung 23 (Fig. 2 und 3) besteht aus einem Deckel 26 und einem Rahmen 27. Deckel 26 und Rahmen 27 sind einteilig durch Formgießen oder Warmformen aus einem thermoplastischen Kunststoff, wie Polyäthylen, Polypropylen hergestellt. Der Deckel 26 ist mit einem Rand mit dem Rahmen 27 scharnierartig verbunden (Fig. 3). An dem dem Verbindungsrand gegenüberliegenden Rand hat der Deckel 26 eine vorstehende Grifflasche 30, der im Rahmen 27 eine entsprechende Aussparung 31 zugeordnet ist. Ferner hat der Deckel 26 auf seiner Unterseite Versteifungsrippen 32. In geschlossenem Zustand greift der Deckel 26 in den Rahmen 27 ein und schließt staubdicht (Fig. 2), Der formsteife Rahmen 27 hat einen L-förmigen Querschnitt, dessen waagerechter Schenkel 28 mit dem Deckel 26 als Verschluß zusammenwirkt und dessen senkrechter Schenkel 29 an der Innenseite des Beutels 21 befestigt ist. Die Wiederverschlußeinrichtung 23 ist im Kopfbereich des Beutels 21 so angeordnet, daß der Deckel 26 und der waagerechte Schenkel 28 des Rahmens 27 an der Kopfwand 33 des Beutels 21 anliegen, und daß der senkrechte Schenkel 29 des Rahmens 27 etwa in der Mitte seiner Höhe ringsum durch eine Schweißnaht 34 mit den vier Seitenwänden 35 des Beutels 21 verschweißt ist.The reclosure device 23 arranged in the bag 21 (FIGS. 2 and 3) consists of a lid 26 and a frame 27. The lid 26 and frame 27 are made in one piece by molding or thermoforming from a thermoplastic material, such as polyethylene, polypropylene. The cover 26 is connected with an edge to the frame 27 in a hinge-like manner (FIG. 3). On the edge opposite the connecting edge, the cover 26 has a protruding grip tab 30, to which a corresponding recess 31 is assigned in the frame 27. Furthermore, the cover 26 has stiffening ribs 32 on its underside. In the closed state, the cover 26 engages in the frame 27 and closes in a dust-tight manner (FIG. 2). The dimensionally stable frame 27 has an L-shaped cross section, the horizontal leg 28 of which with the Lid 26 cooperates as a closure and its vertical leg 29 is attached to the inside of the bag 21. The reclosing device 23 is arranged in the head region of the bag 21 so that the lid 26 and the horizontal leg 28 of the frame 27 rest against the head wall 33 of the bag 21, and that the vertical leg 29 of the frame 27 is approximately in the middle of its height all around a weld 34 is welded to the four side walls 35 of the bag 21.

Oberhalb der Schweißnaht 34 ist auf der Innenseite der Seitenwände 35 des Beutels 21 ein Aufreißband 37 ringsum angesiegelt, das mit einem Ende durch die Längsnaht 36 des Beutels 21 nach außen ragt (Fig. 13).Above the weld seam 34, a tear tape 37 is sealed all around on the inside of the side walls 35 of the bag 21, one end projecting outwards through the longitudinal seam 36 of the bag 21 (FIG. 13).

Der den Beutel 21 umgebende Außenbehälter 22 besteht aus Karton. Er ist mit dem Beutel 21 durch Klebepunkte 39 verbunden, die etwa in Höhe des unteren Teils des senkrechten Schenkels 29 des Rahmens 27 liegen. Die Klebepunkte 39 bestehen vorzugsweise aus einem Heißkleber. Oberhalb der Klebepunkte 39 sind in den Außenbehälter 22 Perforationslinien 40 eingestanzt, welche einen Reißstreifen 41 begrenzen.The outer container 22 surrounding the bag 21 is made of cardboard. It is connected to the bag 21 by adhesive dots 39 which are approximately at the level of the lower part of the vertical leg 29 of the frame 27. The adhesive dots 39 preferably consist of a hot glue. Perforation lines 40, which delimit a tear strip 41, are punched into the outer container 22 above the adhesive dots 39.

Die beschriebene Packung wird vorzugsweise auf einer Maschine mit mehreren Formdornen, die mehrere Bearbeitungsstationen durchlaufen, wie folgt hergestellt :

  • Zunächst wird auf die Stirnseite eines Formdorns 50 die Wiederverschlußeinrichtung 23 so aufgesetzt, daß die senkrechten Schenkel 29 des Rahmens 27 den Formdorn 50 umfassen (Fig. 4). Auf einer zweiten Station wird um den Formdorn 50 ein Packstoffblatt zu einer Hülse 51 herumgefaltet und dessen Längsränder zu der Längsnaht 36 des Beutels verschweißt (Fig. 5). Zuvor ist auf das Packstoffblatt das Aufreißband 37 so aufgeschweißt worden, daß ein Ende das Packstoffblatt an einem Rand überragt, so daß dieses Ende aus der Längsnaht 36 herausragt. Gleichzeitig mit dem Schweißen der Längsnaht 36 wird die Hülse 51 mit den senkrechten Schenkeln 29 des Rahmens 27 ringsum verschweißt (Schweißnaht 34). Daraufhin wird der die Wiederverschlußeinrichtung 23 überragende Teil der Hülse 51 flachgezogen, auf die Wiederverschlußeinrichtung 23 gefaltet, wobei abstehende, dreieckige Ohren 52 entstehen, und durch eine Querschweißnaht 53 dicht verschlossen, so daß dieser Teil die zuvor beschriebene Kopfwand 33 bildet (Fig. 6). Die zunächst mit der Kopfwand 33 in einer Ebene liegenden Ohren 52 werden auf die Kopfwand 33 umgefaltet (Fig.7).
The package described is preferably produced as follows on a machine with multiple mandrels that pass through several processing stations:
  • First of all, the reclosing device 23 is placed on the end face of a shaping mandrel 50 such that the vertical legs 29 of the frame 27 encompass the shaping mandrel 50 (FIG. 4). At a second station, a sheet of packaging material is folded around the mandrel 50 to form a sleeve 51 and its longitudinal edges are welded to the longitudinal seam 36 of the bag (FIG. 5). The tear tape 37 has previously been welded onto the packaging material sheet such that one end projects beyond the packaging material sheet at one edge, so that this end protrudes from the longitudinal seam 36. Simultaneously with the welding of the longitudinal seam 36, the sleeve 51 is welded all around with the vertical legs 29 of the frame 27 (weld seam 34). Then the part of the sleeve 51 projecting beyond the reclosure device 23 is pulled flat, folded onto the reclosure device 23, whereby protruding triangular ears 52 are formed, and sealed by a transverse weld seam 53, so that this part forms the head wall 33 described above (FIG. 6) . The ears 52, which are initially in one plane with the head wall 33, are folded over onto the head wall 33 (FIG. 7).

Um den so geformten Beutel 21, der noch auf dem Formdorn 50 sitzt, wird ein Kartonzuschnitt herumgefaltet und zu einer Hülse 54 geformt (Fig. 8). In dem Querstreifen, der in Deckung mit dem senkrechten Schenkel 29 des Rahmens 27 zu liegen kommt, sind zuvor die Klebepunkte 39 aufgetragen worden, die die Hülse 54 mit dem Beutel 21 fest verbinden. Anschließend werden die ebenfalls mit Klebstoff versehenen Kopffaltlaschen 55 des Kartonzuschnitts auf die Kopfwand 33 des Beutels 21 umgefaltet und miteinander zu einer Kopfwand 58 verklebt (Fig. 9).A cardboard blank is folded around the thus shaped bag 21, which is still seated on the forming mandrel 50, and formed into a sleeve 54 (FIG. 8). In the transverse stripe, which comes to coincide with the vertical leg 29 of the frame 27, the adhesive spots 39 have been applied beforehand, which firmly connect the sleeve 54 to the bag 21. Subsequently, the top folding flaps 55 of the cardboard blank, which are also provided with adhesive, are folded over onto the top wall 33 of the bag 21 and glued together to form a top wall 58 (FIG. 9).

Der so geformte leere Verpackungsbehälter wird sodann vom Formdorn 50 abgezogen und so aufgestellt, daß der an einem Ende gebildete Verschluß des Behälters vorübergehend den Boden bildet (Fig. 10). In dieser Lage wird der Behälter gefüllt. Nach dem Füllen des Beutels 21 wird dessen offenes Ende ähnlich wie oben bei der Herstellung der Kopfwand 33 beschrieben als Bodenwand 56 dicht verschlossen und gefaltet. Auch werden die Bodenfaltlaschen 57 des Kartonzuschnitts auf die Bodenwand 56 des Beutels 21 umgelegt und miteinander zu einer Bodenwand des Außenbehälters 22 verklebt. Danach wird die Packung gedreht, so daß ihr Kopf mit den Kopfwänden 33 und 58 und der Wiederverschlußeinrichtung 23 oben ist (Fig. 12).The empty packaging container thus formed is then pulled off the mandrel 50 and set up so that the closure of the container formed at one end temporarily forms the bottom (FIG. 10). The container is filled in this position. After the bag 21 has been filled, its open end is sealed and folded as the bottom wall 56 in a manner similar to that described above in the manufacture of the top wall 33. The bottom folding flaps 57 of the cardboard blank are folded over onto the bottom wall 56 of the bag 21 and glued together to form a bottom wall of the outer container 22. The package is then rotated so that its head with the head walls 33 and 58 and the reclosable device 23 is at the top (FIG. 12).

Die so hergestellte Packung läßt sich wie folgt öffnen :

  • Zunächst wird der von den Perforationslinien 40 begrenzte Reißstreifen 41 des Außenbehälters 22 durch Ziehen entfernt und die Kopfwand 58 des Außenbehälters 22 abgenommen (Fig. 13), so daß die Kopfwand 33 des Beutels 21 freiliegt. Danach erfaßt man das vorstehende Ende des Aufreißbandes 37 und trennt durch Ziehen an diesem die Kopfwand 33 des Beutels 21 von dessen Seitenwänden ab. Nach Entfernen der Kopfwand 33 ist die Packung zum mehrmaligen Öffnen und Wiederverschließen vorbereitet. Durch Erfassen der Grifflasche des Deckels 26 wird der Deckel 26 hochgeschwenkt. Nach Entnehmen eines Teils des verpackten Guts wird der Deckel 26 wieder in den Rahmen 27 gedrückt, wo er einen staubdichten Sitz hat. Die Packung läßt sich auf diese Weise wiederholt Öffnen und Verschließen sowie bequem stapeln.
The pack produced in this way can be opened as follows:
  • First, the tear strip 41 of the outer container 22 delimited by the perforation lines 40 is removed by pulling and the top wall 58 of the outer container 22 is removed (FIG. 13), so that the top wall 33 of the bag 21 is exposed. Thereafter, the protruding end of the tear tape 37 is grasped and the head wall 33 of the bag 21 is separated from the side walls thereof by pulling on it. After removal of the top wall 33, the pack is prepared for repeated opening and closing. By gripping the grip tab of the cover 26, the cover 26 is pivoted up. After removing part of the packaged goods, the cover 26 is pressed back into the frame 27, where it has a dustproof seat. In this way, the package can be opened and closed repeatedly and conveniently stacked.

Ergänzend wird darauf hingewiesen, daß die eingangs geschilderten Vorteile auch bei einer Packung vorhanden sind, die keinen Außenbehälter 22 hat.In addition, it is pointed out that the advantages described at the outset are also present in a package that does not have an outer container 22.
