In a wrapper for chocolates, the cover is formed by a blank (4) of a multilayered packaging material which has a hot-sealable decorative varnished layer on the decorated side and a hot-sealing layer on its other side on a partial region (5) of its surface. In the wrapper, the chocolate is wrapped in the blank (4) with formation of two mutually overlapping envelope folds (11, 12) at the bottom (13) of the chocolate, the hot-sealing layer of the partial region (5) being connected by hot-sealing at the envelope fold (12) to the decorative upper side of the material of the envelope fold (11). In this case, the blank (4) has at least one labelling square (8) on the decorated side, inside which labelling (9) is applied by the packaging material being embossed, while a frame-type support profile (10) is provided along the edge of the blank in the form of an embossing of the packaging material. <IMAGE>

Description

Die Erfindung betrifft eine Einschlagpackung für Pralinen, bei der die Praline in eine dekorative bedruckte Hülle aus einem flächigen und flexiblen sowie heißsiegelfähigen Verpackungsmaterial eingeschlagen ist und dabei am Pralinenboden zwei einander überlappende Kuvertfaltungen aufweist, die zum Verschließen der Hülle durch Heißsiegelung miteinander verbunden sind.The invention relates to a wrapping package for chocolates, in which the praline is wrapped in a decorative printed envelope made of a flat and flexible and heat-sealable packaging material and has two overlapping envelope folds on the chocolate bottom, which are connected to one another by heat sealing to close the envelope.

Eine bekannte Einschlagpackung für Pralinen dieser Art weist eine zweilagige Hülle auf, die aus zwei übereinanderliegenden Zuschnitten gebildet wird, wobei der an der Hüllenaußenseite zu liegen kommende Zuschnitt aus einer dekorativ bedruckten Folie aus biaxial gerecktem Polypropylen (OPP) und der packungsgutseitige Zuschnitt aus einem Verbund besteht, der dekorseitig eine mit einer Grundfarbe lackierte Aluminiumfolie umfaßt, welche packungsgutseitig mit einer Papierlage verbunden ist. An der Verpackungsmaschine werden die bedruckte OPP-Folie und die Verbundfolie jeweils in Bandform von der Rolle abgezogen, beide Zuschnitte abgelängt und mit einer überstehenden Kante des OPP-Folienzuschnittes übereinanderliegend dann der Einschlag über die Praline hergestellt und schließlich an den beiden einander überlappenden Kuvertfaltungen durch kurzzeitiges Andrücken eines heißen Siegelwerkzeuges die überstehende Kante der OPP-Folie an der zuoberst liegenden Kuvertfaltung mit der äußeren OPP-Folienlage der darunterliegenden Kuvertfaltung durch Heißsiegelung miteinander verbunden.A known wrapping package for chocolates of this type has a two-layer casing, which is formed from two blanks lying one above the other, the blank coming to lie on the outside of the wrapper consisting of a decorative printed film made of biaxially stretched polypropylene (OPP) and the blank on the package side consisting of a composite which, on the decor side, comprises an aluminum foil painted with a base color, which is connected to a paper layer on the packaged goods side. On the packaging machine, the printed OPP film and the composite film are each pulled off the roll in tape form, both cuts are cut to length and with a protruding edge of the OPP film cut lying one above the other then the wrap is made over the chocolate and finally on the two overlapping envelope folds by briefly Press on a hot sealing tool and connect the protruding edge of the OPP film on the envelope fold on the top to the outer OPP film layer of the envelope fold underneath by heat sealing.

Diese bekannte Einschlagpackung für Pralinen ist nun aber im Aufbau und ihrer Herstellung sehr aufwendig: Der Verpackungsmaschine müssen zwei Verpackungsmaterialbahnen zugeführt werden, die dann voneinander unabhängig in Zuschnitte abgelängt und in definierter Weise aufeinandergelegt werden, um das Hüllenmaterial, in das die Praline eingeschlagen wird, zu bilden.However, this well-known wrapping package for chocolates is now very complex to build and manufacture: the packaging machine must be fed two webs of packaging material, which are then cut to length independently and laid on top of one another in a defined manner in order to enclose the wrapping material into which the chocolate is wrapped form.

Hier will die Erfindung Abhilfe schaffen. Der Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, eine Einschlagpackung der eingangs der Beschreibung genannten Art anzugeben, die weniger aufwendig ist und die man einfacher herstellen kann als die vorstehend beschriebene Packung.The invention seeks to remedy this. The invention, as characterized in the claims, achieves the object of specifying a wrapping package of the type mentioned at the beginning, which is less complex and which is easier to produce than the package described above.

Die Erfindung wird nachstehend anhand eines Beispiels eingehend erläutert.The invention is explained in detail below using an example.

Zur Herstellung der Hülle der Einschlagpackung wird eine Aluminiumfolienbahn einer Dicke zwischen 0,007 bis 0,015 mm, insbesondere jedoch von 0,010 mm an einer Seite in einer Grundfarben-Vorlackierung mit einem wäßrigen Acrylatlack versehen und an der anderen Seite mit einem Naßkaschierkleber auf Styrol-Butadienbasis mit einer Auftragsmenge von ca. 1,5 g/m² mit einer Sulfitpapierbahn einer Grammatur zwischen 20 und 40 g/m² verbunden. Die Breite der so hergestellten Verpackungsmaterialbahn beträgt ein Mehrfaches der späteren Länge l des zum Einschlagen der Praline verwendeten Verpackungmaterial-Zuschnitts.To produce the wrapper of the wrapping package, an aluminum foil web with a thickness between 0.007 to 0.015 mm, but in particular 0.010 mm, is provided on one side with a primer primer coat with an aqueous acrylate lacquer and on the other side with a wet laminating adhesive based on styrene-butadiene with an application amount 1.5 g / m² with a sulfite paper web with a grammage between 20 and 40 g / m². The width of the web of packaging material thus produced is a multiple of the later length l of the packaging material blank used for wrapping the chocolate.

Das Verpackungsmaterial wird in der Folge - nach Unterteilung - in Einzelbahnen einer Breite gleich der späteren Zuschnittslänge an den Verpacker geliefert.The packaging material is then - after subdivision - delivered to the packer in individual webs with a width equal to the later cut length.

Fig. 1 zeigt in der Aufsicht auf die dekorative Vorderseite einen Ausschnitt einer solchen Einzelbahn 1 mit einer Breite gleich Zuschnittslänge 1 und den seitlichen Schnittkanten 2 sowie den Linien 3, längs denen die Verpackungsmaterialbahn 1 in der Verpackungsmaschine in Zuschnitte 4 unterteilt wird. Mit 5 ist der rechteckige Teilbereich bezeichnet, in dem auf der Verpackungsmaterialrückseite der Heißkleberlack aufgedruckt ist, während an der dekorativen Vorderseite Tastmarken 6 aufgedruckt sind, mit Hilfe von denen das Ablängen der Bahn in Zuschnitte gesteuert wird. Die Verpackungsmaterialbahn weist an ihrer dekorativen Seite innerhalb des jeweiligen Zuschnitts 4 eine mit 7 angedeutete sogenannte Seidenglanzprägung mit der Struktur eines feinen Kreuzlinienrasters auf. Diese Seidenglanzprägung 7 ist innerhalb eines z.B. rechteckigen Zeichenfeldes 8, die eine andere Grundfarbe als die restliche Oberfläche aufweist, ausgespart. In diesem Zeichenfeld 8 ist das Verpackungsmaterial innerhalb einer aufgebrachten Beschriftung 9 bzw. Zeichen vorteilhaft hochgeprägt.Fig. 1 shows a top view of the decorative front of a section of such a single web 1 with a width equal to the cut length 1 and the lateral cut edges 2 and the lines 3, along which the packaging material web 1 is divided into cuts 4 in the packaging machine. 5 designates the rectangular partial area in which the hot-melt adhesive lacquer is printed on the back of the packaging material, while tactile marks 6 are printed on the decorative front side, with the aid of which the cutting to length of the web is controlled in blanks. The packaging material web has on its decorative side inside of the respective blank 4 has a so-called silk gloss embossing, indicated by 7, with the structure of a fine cross line grid. This silk gloss embossing 7 is left out of a rectangular drawing field 8, for example, which has a different basic color than the rest of the surface. In this character field 8, the packaging material is advantageously embossed within an applied label 9 or character.

Zum Anbringen des dekorativen Aufdruckes und der Prägungen an der Verpackungsamterialbahn wird wie folgt vorgegangen.The procedure for attaching the decorative print and embossing to the packaging material web is as follows.

Die wie weiter oben beschrieben hergestellte Verpackungsmaterialbahn wird an der vorlackierten Seite mittels eines Tiefdruckverfahrens z.B. in einem Mehrfarbendruckwerk mit einem dekorativen bzw. informativen Aufdruck auf Nitrolackbasis versehen und in einem sogenannten Widerdruckwerk an der Verbundrückseite in einem begrenzten Feld ein Heißschmelzlack auf Basis von EVA mit einer Auftragsmenge von etwa 3 - 4 g/m² aufgedruckt.Danach durchläuft die Verpackungsmaterialbahn hintereinander zwei Prägestationen. In der ersten wird die Kreuzlinienstruktur durch Tiefprägung - mit einer Tiefe von 0,010 - 0,035 mm, insbesondere von 0,020 mm und etwa 33 Linien pro cm - hergestellt, wobei die Zeichenfelder 8 ausgespart bleiben. In der zweiten Prägestation erfolgen dann die Hochprägungen innerhalb der Beschriftung 9 sowie innerhalb eines rahmenförmigen Bereiches entlang des Zuschnittrandes - in etwa in derselben Höhe wie innerhalb der Beschriftung 9 - zur Bildung eines sogenannten Stützprofils 10. Die Höhe der Hochprägung beträgt dabei zwischen 0,010 und 0,035 mm, insbesondere aber 0,015 mm. Die so hergestellte Verpackungsmaterialbahn wird dann in Einzelbahnen 1 einer Breite l gleich der späteren Zuschnittslänge unterteilt und aufgerollt. Durch das Stützprofil 10 wird verhindert, daß die Hochprägungen innerhalb der Beschriftungen 9 beim Aufrollen der Verpackungsmaterialbahn bzw. der Einzalbahnen 1 wieder plattgedrückt werden.The packaging material web produced as described above is provided with a decorative or informative print on a nitro lacquer base on the pre-coated side using a gravure printing process, e.g. in a multi-color printing unit, and in a so-called back printing unit on the back of the composite in a limited area a hot melt lacquer based on EVA with an order quantity 3 - 4 g / m² printed on the packaging material. Then the packaging material web passes through two embossing stations in succession. In the first, the cross line structure is produced by deep embossing - with a depth of 0.010-0.035 mm, in particular 0.020 mm and about 33 lines per cm - the character fields 8 being left out. In the second embossing station, the embossing takes place within the inscription 9 and within a frame-shaped area along the cutting edge - at approximately the same height as within the inscription 9 - to form a so-called support profile 10. The height of the embossing is between 0.010 and 0.035 mm , but especially 0.015 mm. The packaging material web thus produced is then divided into single webs 1 of a width l equal to the later cut length and rolled up. The support profile 10 prevents the embossments within the inscriptions 9 from being flattened out again when the packaging material web or the individual webs 1 are rolled up.

Die Pralinen werden dann in üblicher Weise in der Verpackungsmaschine in die Zuschnitte eingeschlagen.The chocolates are then wrapped in the blanks in the usual way in the packaging machine.

Fig. 2 zeigt in perspektivischer Darstellung eine Phase des Einschlagvorganges, bevor die Kuvertfaltungen 11 bzw. 12 auf den Pralinenboden 13 umgeschlagen werden. An der Kuvertfalte 12 erkennt man den Teilbereich 5 mit dem Heißkleberlackaufdruck. Danach wird zuerst die Kuvertfaltung 11 und danach die Kuvertfaltung 12 auf den Pralinenboden umgeschlagen, so daß sich die in Fig. 3 gezeigte Phase ergibt, welche schon die endgültige Form der Einschlagpackung zeigt. Durch kurzzeitiges Aufdrücken eines beheizten Siegelstempels in Richtung des Pfeiles 14 auf die umgeschlagene Kuvertfaltung 12, welche den mit Heißkleberaufdruck versehenen Teilbereich 5 aufweist, verbindet sich dieser mit der dekorativen Oberfläche des Materials der Kuvertfaltung 11, womit die Herstellung der Einschlagpackung beendet ist.Fig. 2 shows a perspective view of a phase of the wrapping process before the envelope folds 11 and 12 are folded onto the chocolate base 13. On the envelope fold 12 one can see the partial area 5 with the hot-melt lacquer print. Then the envelope fold 11 and then the envelope fold 12 is folded over onto the praline base, so that the phase shown in FIG. 3 results, which already shows the final shape of the wrapping package. By briefly pressing a heated sealing stamp in the direction of arrow 14 onto the folded envelope fold 12, which has the partial area 5 provided with hot-glue printing, it connects to the decorative surface of the material of the envelope fold 11, thus completing the production of the wrapper.

Die Heißsiegelung, welche die Hülle der Einschlagpackung fixiert, kann zum Entfernen der Packungshülle leicht aufgeschält werden.The heat seal, which fixes the wrapper of the wrapper, can be peeled off easily to remove the wrapper.
