The inner package (10) consists of grease-proof paper or similar, has a heat-resistant coating on its outside and has a longitudinal seam (12), in which the inner surfaces of the edges (13, 15) are bonded together. One of the two edge strips (13a) is extended and folded over so that it rests next to the longitudinal seam (12) with its inside turned outwards and it is bonded in a separable manner to the inside of an inner closure flap (7) of the folding box. For closing the folding box, firstly dust flaps (8) are folded in and at least the edges of the inner package (10) are squeezed together, then the inner closure flaps (7) and the outer closure flaps (6) are folded in. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Kartonverpackung für im wesentlichen feste Lebensmittel und ähnliches Füllgut. Sie ist insbesondere für halbfertige Backwaren geeignet. Sie besteht aus einer beutelartigen Innenverpackung, die das Lebensmittel aufnimmt und aus einer Faltschachtel, die die Innenverpackung umgibt.The invention relates to a cardboard packaging for essentially solid foods and similar contents. It is particularly suitable for semi-finished baked goods. It consists of a bag-like inner packaging that holds the food and a folding box that surrounds the inner packaging.

Die Innenverpackung besteht zweckmässigerweise aus einem Material, das bei der Zubereitung des Lebensmittels, insbesondere bei der erneuten Erwärmung, vorteilhaft als Unterlage oder Umhüllung verwendbar ist. Ein solches geeignetes Material ist beispielsweise Pergamentersatzpapier, und es ist für diesen Verwendungszweck günstig, wenn ein derartiges Papier auf seiner Aussenseite hitzebeständig und antiadhäsiv beschichtet ist. Ein besonders geeignetes Material ist ein aussen mit Silicon beschichtetes Pergamentersatzpapier, welches auch an heissen Pfannen, Backblechen o.ä. nicht haftet. Diese Beschichtung ist allerdings auch klebstoffabweisend.The inner packaging expediently consists of a material which can advantageously be used as a base or wrapping when preparing the food, in particular when reheating it. Such a suitable material is, for example, parchment replacement paper, and it is advantageous for this purpose if such paper is coated on its outside with a heat-resistant and anti-adhesive coating. A particularly suitable material is a silicone coated outside with greaseproof p aper, which is also on hot pans, baking trays, etc. is not liable. However, this coating is also adhesive-repellent.

Für den Verpackungsvorgang entstehen bei der Verwendung von sehr glatten und antiadhäsiv beschichteten Papieren jedoch einige Schwierigkeiten, da diese Papiere von den üblichen Halterungsmitteln und Faltwerkzeugen der Verpackungsmaschinen kaum oder nur mit ziemlichen Ungenauigkeiten erfasst und gehalten werden können.However, there are some difficulties for the packaging process when using very smooth and anti-adhesive coated papers, since these papers can hardly be grasped and held with the usual holding means and folding tools of the packaging machines or only with considerable inaccuracies.

Durch die Erfindung soll eine Verpackung mit einer antiadhäsiv beschichteten beutelartigen Innenverpackung so verbessert werden, dass ein einfacher Verpackungsvorgang möglich ist.The invention is intended to improve packaging with an anti-adhesive coated bag-like inner packaging in such a way that a simple packaging process is possible.

Die Erfindung betrifft auch das Verfahren zum Verschliessen der verbesserten Verpackung, wobei die beutelartige Innenverpackung an wenigstens einem Ende gleichzeitig mit dem Verschliessen der Faltschachtel abgeschlossen und in der Faltschachtel befestigt werden soll.The invention also relates to the method for closing the improved packaging, the bag-like inner packaging being to be closed at least at one end at the same time as the folding box is being closed and to be fastened in the folding box.

Nach der Erfindung ist vorgesehen, dass die beutelartige oder schlauchförmige Innenverpackung aus einem aussenseitig hitzebeständig und antiadhäsiv beschichteten Material, vorzugsweise aus mit Silicon beschichtetem Pergamentersatzpapier, eine Längsnaht besitzt, bei der die Ränder der Innenfläche zusammengeklebt sind und ein Rand über diese Längsnaht so verlängert und umgefaltet ist, dass ein Streifen der Innenfläche neben der Längsnaht nach aussen weist und dieser Streifen oder Teile dieses Streifens an Innenseiten des Faltschachtelzuschnitts angeklebt sind, wobei vorzugsweise die Verbindungen zwischen der Innenverpackung und der Faltschachtel lösbar sind, um die beiden Verpackungsteile wieder voneinander trennen zu können.According to the invention it is provided that the bag-like or tubular Innenver ackung p from an outside heat-resistant and anti-adhesive coated material, preferably silicone coated greaseproof papers, a longitudinal seam has, at the edges of the inner surface are stuck together and an edge about this longitudinal seam prolongs and folded over that a strip of the inner surface next to the longitudinal seam points outwards and this strip or parts of this strip are glued to the inside of the folding box blank, the connections between the inner packaging and the folding box preferably being detachable in order to separate the two packaging parts again can.

Es wird vorzugsweise eine Faltschachtel verwendet, die einen mittels einer Längsklebelasche schlauchförmig zusammengeklebten Rumpf und an zwei gegenüberliegenden Seiten Verschlussklappen besitzt. Die Länge der Innenverpackung ist grösser als die in gleicher Richtung (der Längsrichtung des Schachtelrumpfes) zu messende Länge der fertigen Faltschachtel bzw. deren Grundfläche, und die Innenverpackung wird mit dem neben ihrer Längsnaht nach aussen weisenden Streifen ihrer Innenfläche mit wenigstens einer Verschlussklappe der Faltschachtel abtrennbar verklebt. Die Verbindung zwischen der Innenverpackung und dem Faltschachtelzuschnitt erfolgt zweckmässigerweise, bevor der Zuschnitt gefaltet und mittels seiner Längsklebelasche verklebt wird. Zum Einpacken des Lebensmittels wird dann die Faltschachtel aufgerichtet und die Innenverpackung z.B. durch Anblasen ihrer Offnungsseite mit Luft geöffnet.A folding box is preferably used, which has a fuselage which is tubularly glued together by means of a longitudinal adhesive flap and has closure flaps on two opposite sides. The length of the inner packaging is greater than the length of the finished folding box or its base, which is to be measured in the same direction (the longitudinal direction of the box body), and the inner packaging can be separated with at least one closing flap of the folding box with the strip of its inner surface pointing outward along its longitudinal seam glued. The connection between the inner packaging and the folding box blank is expediently made before the blank is folded and glued by means of its longitudinal adhesive flap. To pack the food, the folding box is then erected and the inner packaging e.g. by blowing on their opening side with air.

Nach dem Einschieben des Lebensmittels wird die Verschlussklappe, an der die Innenverpackung befestigt ist,um bis zu 45° nach aussen umgebogen, wodurch sich die öffnungsseitigen Enden der Innenverpackung zusammenlegen. Hierauf werden zunächst die an den schmalen Seiten der Faltschachtel befindlichen sogenannten Staubklappen eingefaltet, die hierbei wenigstens die seitlichen Ränder der Innenverpackung zusammendrücken. Nun wird die innere Verschlussklappe mit dem an ihr befestigten Ende der Innenverpackung eingefaltet. Die Innenverpackung wird hierdurch um eine Kante der Staubklappen um etwa 90° geknickt und somit ausreichend abgeschlossen, und die Enden werden zwischen den Staubklappen und der inneren Verschlussklappe eingeklemmt. Abschliessend wird die äussere Verschlussklappe auf die innere gefaltet und angeklebt oder angesiegelt.After insertion of the food, the closure flap to which the Innenver p is secured ackung to the outside up to 45 ° bent over, whereby the opening-side ends of the inner packaging collapse. The so-called dust flaps located on the narrow sides of the folding box are first folded in, which in this case compress at least the lateral edges of the inner packaging. Now, the inner closure flap is folded with the p ackung attached to an end of the Innenver. The inner packaging is thereby bent around an edge of the dust flaps by about 90 °, and thus sufficiently completed, and the ends are clamped p pe between the dust flaps and the inner Verschlusskla. Finally, the outer Verschlussklap p e is folded and bonded or sealed to the inner.

Insbesondere wenn die Innenverpackung ein an beiden Enden offener Schlauch ist, kann die Faltschachtel an beiden Seiten in der vorstehend beschriebenen Weise verschlossen werden.In particular if the inner packaging is a tube open at both ends, the folding box can be closed on both sides in the manner described above.

Obwohl die antiadhäsiv mit Silicon beschichtete Aussenfläche der Innenverpackung keine Klebeverbindung mit der Faltschachtel ergibt, konnte durch die besondere Ausführung der Längsnaht der Innenverpackung eine Verklebung mit der Schachtel erreicht werden, und hierdurch war es weiter möglich, die in der Schachtel befestigte Innenverpackung so zu handhaben, dass der Verpackungs- und Verschliessvorgang auch mit üblichen, schnellaufenden Verpackungsmaschinen erfolgen kann. Die Befestigung der Innenverpackung durch Ankleben und Einklemmen ihrer Enden hindert diese daran, auf ihrer sehr gleitfähigen Aussenfläche in der Faltschachtel hin und her zu rutschen und trägt somit zum Schutz des verpackten Produkts bei.Although the anti-adhesive silicone-coated outer surface of the inner packaging does not result in an adhesive connection with the folding box, the special design of the longitudinal seam of the inner packaging means that it can be glued to the box, and this also made it possible to handle the inner packaging fastened in the box in this way, that the packaging and sealing process can also be carried out with conventional, high-speed packaging machines. Fastening the inner packaging by gluing and clamping its ends prevents it from sliding back and forth in the folding box on its very slidable outer surface and thus helps to protect the packaged product.

Weitere Einzelheiten der Erfindung werden anhand des Ausführungsbeispiels auf den beigefügten schematischen Zeichnungen beschrieben.

Further details of the invention are described on the basis of the exemplary embodiment in the attached schematic drawings.
  • Fig. 1 shows a folding box blank with glued inner packaging;
  • Fig. 2 shows a longitudinal section through a package that is only partially closed at one end;
  • Fig. 3 shows a section through one end of a closed package according to III-III in Fig. 2;

Der Faltschachtelzuschnitt besteht aus einer Bodenfläche 1, einer oberen Fläche 2, zwei schmalen Seiten 3,4, einer Längsklebelasche 5 und besitzt äussere Verschlussklappen 6, innere Verschlussklappen 7 und Staubklappen 8. - Die Innenverpackung 10 ist ein Seitenfaltenschlauch aus Pergamentersatzpapier, das auf der Aussenfläche eine Beschichtung 11 aus Silicon aufweist. Der Schlauch hat eine Längsnaht 12, bei der nach Umfaltung eines Randes 13 des Schlauchzuschnitts um 180° die Innenflächen beider Ränder 13,15 zusammengeklebt sind. Der umgefaltete Rand 13 ist breiter als für die Längsnaht 12 erforderlich bzw. als der andere Rand 15. Als Folge hiervon weist neben der Längsnaht 12 die Innenfläche des Randes 13 als ein klebefähiger Streifen 13a nach aussen und kann an Klebestellen 14 mit einem Faltschachtelteil, z.B. einer inneren Ver- schlussklappe 7 verklebt werden (Fig. 4).The folding box blank consists of a bottom surface 1, an upper surface 2, two short sides 3,4, a longitudinal glue flap 5 and has outer closure flaps 6, inner closure flaps 7 and dust flaps 8. - The inner package 10 is a gusseted tube from Pergamentersatzpa p ier, which on the outer surface has a coating 11 made of silicone. The tube has a longitudinal seam 12, in which, after folding over an edge 13 of the tube blank by 180 °, the inner surfaces of both edges 13, 15 are glued together. The folded edge 13 is wider than is required for the longitudinal seam 12 or as the other edge 15. As a result of this, in addition to the longitudinal seam 12, the inner surface of the edge 13 points outwards as an adhesive strip 13a and can be bonded to a folding box part, for example an inner closing flap p e 7 (FIG. 4).

Nach dem Auflegen der Innenverpackung 10 auf die Bodenfläche 1 und die an ihr befindlichen inneren Verschlussklappen 7 werden die Streifen 13a punktförmig an den Klebestellen 14 mit dem Faltschachtelzuschnitt verbunden, der Zuschnitt zusammengefaltet und die Längsklebelasche 5 verklebt.After the inner packaging 10 has been placed on the bottom surface 1 and the inner closure flaps 7 located thereon, the strips 13a are connected to the folding box blank in a punctiform manner at the adhesive points 14, the blank is folded together and the longitudinal adhesive tab 5 is glued.

Für den Verpackungsvorgang wird die Faltschachtel aufgerichtet, die Innenverpackung geöffnet und das Füllgut eingeschoben. Zum Verschliessen der Verpackung wird die innere Verschlussklappe 7 zunächst nach aussen, also entgegen der Verschliessrichtung umgebogen. Dabei ziehen sich die Enden der Innenverpackung 10 zusammen und'liegen etwa an der Biegekante zwischen Bodenfläche 1 und innerer Verschlussklappe 7 an. Nun werden die Staubklappen 8 eingefaltet, wobei wenigstens die Seitenfalten der Innenverpackung zwischen einer Kante der Staubklappen 8 und der Bodenfläche 1 eingeklemmt werden. Jetzt wird die innere Verschlussklappe 7 mit dem an ihr befestigten Ende der Innenverpackung 10 gegen die Staubklappen 8 gefaltet. Die vorherige Einklemmung der Seitenfalten führt zu einer verhältnismässig scharfen Knickung der Innenverpackung 10, die auf diese Weise sowie auch durch die Einklemmung ihres Endes zwischen den Staubklappen 8 und den inneren Verschlussklappen 7 recht gut verschlossen wird. Danach werden die äusseren Verschlussklappen 6 auf den inneren Klappen 7 befestigt.For the packaging process, the folding box is erected, the inner packaging is opened and the contents are inserted. To close the packaging, the inner closure flap 7 is first bent outwards, that is to say against the closing direction. The ends of the inner packaging 10 contract and lie approximately on the bending edge between the bottom surface 1 and the inner closure flap 7. The dust flaps 8 are now folded in, at least the side folds of the inner packaging being clamped between an edge of the dust flaps 8 and the bottom surface 1. Now the inner closure flap 7 is folded against the dust flaps 8 with the end of the inner packaging 10 attached to it. The previous clamping of the side folds leads to a relatively sharp kinking of the inner packaging 10, which is closed quite well in this way and also by the clamping of its end between the dust flaps 8 and the inner closing flaps 7. Then the outer flaps 6 are attached to the inner flaps 7.

Die Klebestellen 14 halten die Innenverpackung 10 bis nach dem Einschieben des nicht dargestellten Füllguts, z.B. eines runden gefrorenen Pizza-Bodens, sicher in der Faltschachtel fest und ermöglichen damit einen mechanischen Verpackungsvorgang in die mit Silicon beschichtete Innenverpackung. Diese und somit auch das Füllgut werden zusätzlich durch die Einklemmung der Enden gut in der Schachtel gehalten. Nach dem Offnen der Schachtel kann die nur punktweise angeheftete Innenverpackung leicht von der Schachtel gelöst und mit dem Füllgut entnommen werden. Die Innenverpackung kann dann bei der weiteren Zubereitung des verpackten Lebensmittels, z.B. als Unterlage unter der Pizza auf einem Backblech oder in ähnlicher Weise als Schutzpapier verwendet werden. Dabei kann die Längsnaht um 1800 umgefaltet werden, so dass die nicht beschichtete Seite des Streifens 13a nicht mehr nach aussen weist.The adhesive points 14 hold the inner packaging 10 securely in the folding box until after the filling material (not shown), for example a round frozen pizza base, has been pushed in, and thus enable a mechanical packaging process into the silicone-coated inner packaging. These and thus the contents are also held well in the box by clamping the ends. After opening the box, the inner packaging, which is only pinned on at points, can easily be detached from the box and removed with the contents. The Innenver p ackung may then during further preparation of the packaged food may be used as a base of the pizza on a griddle or in a similar manner as release paper, for example. The longitudinal seam can be folded over by 180 0, so that the non-coated side 13a does not have the outside to the more the strip.

Der beschriebene Vorgang des Verschliessens der Schachtel kann natürlich auch in dem Falle mit Vorteil angewendet werden, dass das Lebensmittel erst in eine beutelartige Innenverpackung eingebracht und danach in dieser Innenverpackung in die aufgerichtete Faltschachtel eingeschoben wird. Auch in diesem Fall erfolgt nun eirepunktweise Verklebung zwischen dem Streifen 13a und der inneren Verschlussklappe 7 und darauf der oben beschriebene Faltvorgang, durch den die Lage der Innenverpackung in der Faltschachtel gesichert wird.The described process of closing the box can of course also be used advantageously in the event that the food is first introduced into a bag-like inner packaging and then inserted into the erected folding box in this inner packaging. In this case too, there is now a point-by-point gluing between the strip 13a and the inner closure flap 7 and then the folding process described above, by means of which the position of the inner packaging in the folding box is secured.
