Description

Einschlaσpackunσ Wrapping package
Technisches GebietTechnical field
Die Erfindung betrifft eine Einschlagpackung, bei der ein stückiges, gegegebenenfalls unterteilbares Packungsgut in eine äußere Hülle aus einem flächigen und flexiblen Verpackungsmate¬ rial eingeschlagen ist, wobei am Packungsboden einander über¬ lappende Randbereiche des Verpackungsmaterials durch Siegelung oder Klebung miteinander verbunden sind.The invention relates to a wrapping package in which a lumpy, optionally divisible packaged item is wrapped in an outer casing made of a flat and flexible packaging material, overlapping edge regions of the packaging material being connected to one another by sealing or adhesive bonding on the package bottom.
Stand der TechnikState of the art
Eine bekannte Einschlagpackung dieser Art, die zum Verpacken von Pralinen dient, 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 übereinander- liegend 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 darunterlie¬ genden Kuvertfaltung durch Heißsiegelung miteinander verbunden.A known wrapping package of this type, which is used for packaging chocolates, 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 casing made of a decorative printed film made of biaxially stretched polypropylene (OPP) and the Cut on the packaged goods side consists of a composite which, on the decor side, comprises an aluminum foil painted with a base color, which is connected on the packaged goods side to a paper layer. 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 praline and finally on the two overlapping envelope folds by briefly pressing a hot sealing tool, the protruding edge of the OPP film on the envelope fold lying at the top is connected to one another by heat sealing with the outer OPP film layer of the envelope fold underneath.
Diese bekannte Einschlagpackung für Pralinen ist nun aber im Aufbau und ihrer Herstellung sehr aufwendig: Der Verpackungsma¬ schine müssen zwei Verpackungsmaterialbahnen zugeführt werden, die dann voneinander unabhängig in Zuschnitte abgelängt und in definierter Weise aufeinandergelegt werden, um das Hüllenmate¬ rial, in das das Packungsgut eingeschlagen wird, zu bilden.However, this known wrapping package for chocolates is now very complex to construct and manufacture: the packaging machine must be supplied with two webs of packaging material, which are then cut and cut independently of one another are laid on top of one another in a defined manner in order to form the casing material into which the packaged goods are wrapped.
Die in der europäischen Patentanmeldung 480907 beschriebene Ein¬ schlagpackung für Pralinen weist, um den obengenannten Nachteil zu beheben, ein einlagiges, besonders zu behandelndes Verpak- kungsmaterial auf, das in einer vorteilhaften Ausführung aus einem Aluminium-Papier-Verbund besteht.In order to remedy the above-mentioned disadvantage, the wrapping package for chocolates described in European patent application 480907 has a single-layer packaging material which is to be treated and which, in an advantageous embodiment, consists of an aluminum-paper composite.
In vielen Fällen ist jedoch eine Kunststoffolie als oberste Schicht des Verpackungsmaterials gewünscht. Dieser Wunsch würde aber in der Regel zu mehrschichtigen Verpackungsmaterialien führen, bei denen eine Verbindung der am Packungsboden einander überlappenden Verpackungsmaterial-Randbereiche durch eine Siege- lung, von der Art wie sie hier stattfindet, nämlich bei der das Packungsgut der vom Siegelwerkzeug ausgeübten Kraft standhalten muß, nicht oder nur schwer möglich ist.In many cases, however, a plastic film is desired as the top layer of the packaging material. This wish would, however, as a rule lead to multilayer packaging materials in which a connection of the overlapping packaging material edge regions on the packaging base by a seal of the type that takes place here, namely in which the packaging material has to withstand the force exerted by the sealing tool , is not possible or is difficult.
Darstellung der ErfindungPresentation of the invention
Hier will die Erfindung Abhilfe schaffen. Die Erfindung löst die Aufgabe, eine Einschlagpackung der eingangs der Beschreibung genannten Art anzugeben, bei der auch mehrschichtige Ver¬ packungsmaterialien an den einander überlappenden Randbereichen am Packungsboden ohne Probleme durch Siegelung oder Klebung miteinander verbunden werden können.The invention seeks to remedy this. The invention achieves the object of specifying a wrapping package of the type mentioned at the beginning, in which multilayer packaging materials can also be connected to one another without problems by sealing or gluing at the overlapping edge regions on the packaging base.
Diese Aufgabe wird in der erfindungsgemäßen Einschlagpackung dadurch gelöst, daß das Verpackungsmaterial aus zwei unter¬ schiedlichen Schichten oder Schichtverbunden aufgebaut ist und daß die bzw. der dem Packungsgut zugewandte Schicht oder Schichtverbund innerhalb des zuoberst liegenden überlappenden Verpackungsmaterial-Randbereiches eine oder mehrere Aus- oder Durchstanzungen aufweist, innerhalb von der oder denen die beiden Verpackungsmaterial-Randbereiche miteinander verbunden sind. Dabei ist die bzw. der nicht mit Aus- oder Durchstanzungen versehene Schicht oder Schichtverbund vorteilhaft selbst heißsiegelfahig oder an der Unterseite zumindest an den Stellen der Aus- oder Durchstanzungen mit einer heißsiegelfähigen Schicht versehen, die vorzugsweise auch gleichzeitig zum Verbinden der beiden unterschiedlichen Schichten bzw. Schicht¬ verbunde dienen kann.This object is achieved in the wrapping package according to the invention in that the packaging material is made up of two different layers or layer composites and that the layer or layer composite facing the packaged goods has one or more punched or punched-out areas within the overlapping packaging material edge area lying on top has, within which the two packaging material edge regions are connected to one another are. In this case, the layer or layer composite that is not provided with punched or punched holes is itself advantageously heat-sealable or is provided on the underside at least at the locations of the punched or punched holes with a heat-sealable layer which preferably also simultaneously connects the two different layers Layer composites can serve.
In einer vorteilhaften Ausgestaltung der Erfindung ist die heiß- siegelfähige Schicht eine auf Basis eines Heißsiegelwachses.In an advantageous embodiment of the invention, the heat-sealable layer is one based on a heat-sealing wax.
Nach einer anderen vorteilhaften Ausgestaltung der erfindungsge¬ mäßen Einschlagverpackung ist die bzw. der nicht mit Aus- oder Durchstanzungen versehene Schicht oder Schichtverbund an der Unterseite mit einer Dauerkleberbeschichtung versehen, die gleichzeitig vorteilhaft zum Verbinden der beiden unterschied¬ lichen Schichten bzw. Schichtverbunde dienen kann.According to another advantageous embodiment of the wrapping packaging according to the invention, the layer or layer composite that is not provided with punching or punching is provided on the underside with a permanent adhesive coating, which can advantageously also serve to connect the two different layers or layer composite.
Gemäß noch einer vorteilhaften Ausgestaltung der Erfindung ist die nicht mit den Aus- oder Durchstanzungen versehene Schicht zumindest im wesentlichen aus einer gegebenenfalls transparenten Kunststoffolie gebildet.According to yet another advantageous embodiment of the invention, the layer not provided with the punched or punched holes is at least essentially formed from an optionally transparent plastic film.
In einer weiteren Ausgestaltung der Erfindung weist der mit Aus- oder Durchstanzungen versehene Schichtverbund vorteilhaft eine dekorativ und gegebenenfalls mit Aufschriften versehene Alumi¬ niumfolie, die packungsgutseitig über eine Kleberschicht mit einer Papierlage verbunden ist.In a further embodiment of the invention, the layer composite provided with punched or punched holes advantageously has a decorative aluminum foil, optionally with inscriptions, which is connected to a paper layer on the packaged goods side by means of an adhesive layer.
Nach einer noch anderen vorteilhaften Ausgestaltung der Erfindung befinden sich die beiden einander überlappend mitein¬ ander verbundenen Verpackungsmaterial-Randbereiche an zwei am Packungsboden einander überlappenden Kuvertfaltungen des Verpak- kungsmaterials. Gemäß einer letzten vorteilhaften Ausgestaltung der Erfindung ist das Packungsgut eine Praline.According to yet another advantageous embodiment of the invention, the two packaging material edge regions connected to one another overlapping one another are located on two envelope folds of the packaging material that overlap one another on the packaging base. According to a last advantageous embodiment of the invention, the packaged product is a chocolate candy.
Kurze Beschreibung der Zeichnungen im Zusammenhang mit einem vorteilhaften Weg zur Ausführung der ErfindungBrief description of the drawings in connection with an advantageous way of carrying out the invention
Die Erfindung wird nachstehend anhand von Beispielen eingehend erläutert.-The invention is explained in detail below using examples.
Zunächst wird zur Herstellung eines Vorverbundes des Verpackungsmaterials eine Aliminiumfolienbahn einer Dicke zwischen 0,005 bis 0,015 mm, insbesondere jedoch von 0,007 mm an einer Seite in einer Grundfarben-Vorlackierung mit einem wäßrigen Acrylatlack versehen und an der anderen Seite mit einem Naßkaschierkleber z.B. auf Styrol-Butadienbasis mit einer Auftragsmenge von ca. 1,5 g/m2 mit einer Papierbahn einer Grammatur zwischen 18 und 100 g/m2 verbunden. Dieser Vorverbund wird nun in einem weiterem Arbeitsgang bedruckt, sowie, wie später näher erläutert, einer Prägung unterzogen und mit Ausstanzungen versehen. Zur Komplettierung des farbigen Verpackungsmaterials wird dann eine vollflächig mit einem Heißkaschierkleber auf Wachsbasis in einer Auftragsmenge von ca. 5 - 15 g/m2 beschichtete Folienbahn aus, transparentem, biaxial gereckten Polypropylen (OPP) einer Dicke zwischen 0,012 bis 0,030 mm mit der Vorverbundbahn an deren bedruckten Seite durch Heißkaschierung verbunden. Die Breite der so hergestellten Verpackungsmaterialbahn beträgt dabei ein Mehrfaches der späteren Länge b des zum Einschlagen der Praline verwendeten Verpackungsmaterial-Zuschnitts. Das Verpackungsmaterial wird in der Folge - nach Unterteilung - in Einzelbahnen aufgerollt an den Verpacker geliefert.First, to produce a pre-composite of the packaging material, an aluminum foil sheet with a thickness between 0.005 to 0.015 mm, but in particular 0.007 mm, is provided on one side with an aqueous acrylate lacquer in a primary color pre-coating and on the other side with a wet laminating adhesive, for example based on styrene-butadiene an order quantity of approx. 1.5 g / m 2 with a paper web with a grammage between 18 and 100 g / m 2 . This preliminary assembly is now printed in a further operation, and, as will be explained in more detail later, subjected to an embossing and punched out. To complete the colored packaging material, a film of transparent, biaxially stretched polypropylene (OPP) with a thickness of between 0.012 and 0.030 mm is then coated with the pre-bonded film over a full area with a hot-melt wax-based adhesive in an application quantity of approx. 5 - 15 g / m 2 the printed side connected by hot lamination. The width of the packaging material web thus produced is a multiple of the later length b of the packaging material blank used for wrapping the praline. The packaging material is then - after subdivision - delivered to the packer rolled up in individual webs.
Fig. 1 zeigt in der Draufsicht auf die dekorative Vorderseite einen Ausschnitt einer solchen Einzelbahn 1 mit einer Breite b gleich Zuschnittslänge und den seitlichen Schnittkanten 2 sowie aufgedruckten Tastmarken 3, mit deren Hilfe in der Verpackungsmaschine das Ablängen der Bahn 1 in Zuschnitte 4 durch Unterteilung längs den Linien 5 gesteuert wird. Mit 6 sind die bereits erwähnten Ausstanzungen im Aluminium-Papier- Vorverbund 7 (siehe Fig. 4) bezeichnet. Der Vorverbund 7 weist eine mit 8 angedeutete Seidenglanzprägung mit der Struktur eines feinen Kreuzlinienrasters auf, wobei z.B. ein rechteckiges Zeichenfeld 9, das gegebenenfalls eine andere Grundfarbe als die restliche Oberfläche aufweist und in dem die entsprechende Beschriftung aufgedruckt ist, von dieser Seidenglanzprägung ausgespart bleibt.Fig. 1 shows a plan view of the decorative front of a section of such a single web 1 with a width b equal to the cut length and the side cut edges 2 and printed tactile marks 3, with the aid of which the cutting to length of the web 1 into blanks 4 is controlled by subdivision along the lines 5 in the packaging machine. The punchings already mentioned in the aluminum-paper pre-composite 7 (see FIG. 4) are designated by 6. The pre-composite 7 has a silk gloss embossing, indicated by 8, with the structure of a fine cross line grid, for example a rectangular drawing field 9, which may have a different base color than the rest of the surface and in which the corresponding lettering is printed, is left out of this silk gloss embossing.
Beim Verpackungsvorgang werden in der Verpackungsmaschine die Zuschnitte 4 von der Verpackungsmaterialbahn abgelängt und die Pralinen in die Zuschnitte eingeschlagen.During the packaging process, the blanks 4 are cut to length from the packaging material web in the packaging machine and the chocolates are hammered into the blanks.
Fig. 2 ist in perspektivischer Darstellung eine Phase des Ein¬ schlagvorganges dargestellt, bevor die Kuvertfaltungen 10 bzw. 11 auf den Pralinenboden 12 umgeschlagen werden. Man erkennt die rechteckige Ausstanzung 6 im Aluminium-Papier-Vorverbund, innerhalb der die auf der OPP-Folie 13 (siehe Flg. 4) aufgebrachte Heißkleberbeschichtung 15 zutage tritt. Danach wird die Kuvertfaltung 10 und danach die Kuvertfaltung 11 auf den Pralinenboden umgeschlagen, so daß sich die in Fig. 3 gezeigte Phase ergibt, welche schon die endgültige Form der Einschlag¬ packung zeigt. Durch kurzzeitiges Aufdrücken eines beheizten Siegelstempels in Richtung des Pfeiles 14 auf die umgeschlagene Kuvertfaltung 11 innerhalb der Stelle der Ausstanzung 6 wird die OPP-Folie 13 der oben liegenden Kuvertfaltung 11 über die Heißschmelzkleberschicht 15 (siehe Fig. 4) mit der OPP-Folie 13' des Verpackungsmaterials der unten liegenden Kuvertfaltung 10 verbunden. Fig. 4 zeigt schematisch im Schnitt die einander überlappenden Verpackungsmaterial-Randbereiche an der Stelle der Verbindung. Gemäß einer anderen Variante der erfindungsgemäßen Einschlag¬ packung wird zum Verbinden des Vorverbundes 7 und der OPP-Folie 13 statt einer Heißschmelzkleberbeschichtung 15 eine Dauerkle¬ berbeschichtung 15' (pressure-sensitive-Kleberschicht) vollflä¬ chig angebracht, welche in dem Ausschnitt 6 zutage tritt. Die Verwendung von Dauerkleberschichten an der Oberfläche von Verpackungsmaterialien, die insbesondere in Bahnenform auf Rollen aufgewickelt an den Verpacker geliefert werden, ist im allgemeinen nicht üblich, da sich benachbarte Lagen des Verpackungsmaterials an den Stellen der Dauerkleberbeschichtung miteinander verbinden können, d.h., wie man sich auch ausdrückt, das Material in der Rolle "blockt". Überraschenderweise ist das hier nicht der Fall: möglicherweise deshalb, weil zwischen der Dauerkleberbeschichtung 15' innerhalb der Ausschnitte 6 und der darunter liegenden Verpackungsmateriallage in der Rolle Zwi¬ schenräume einer Dicke gleich der des Vorverbundes 7 liegen. Beim Verbinden der beiden Kuvertfaltungen 10, 11 beim Ver¬ packungsvorgang wird aber dieser Zwischenraum durch Andrücken eines Druckstempels mit kleinflächiger Druckfläche an der Stelle des Ausschnitts 6 überbrückt und die Verklebung mit der Ober¬ fläche der untenliegenden Kuvertfaltung hergestellt. 2 shows a perspective illustration of a phase of the wrapping process before the envelope folds 10 and 11 are folded onto the chocolate base 12. One recognizes the rectangular punched-out 6 in the aluminum-paper pre-composite, within which the hot-melt adhesive coating 15 applied to the OPP film 13 (see FIG. 4) is revealed. Then the envelope fold 10 and then the envelope fold 11 are 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 11 within the location of the cut-out 6, the OPP film 13 of the envelope fold 11 lying above is covered with the OPP film 13 'via the hot-melt adhesive layer 15 (see FIG. 4). of the packaging material of the envelope fold 10 lying below. 4 shows schematically in section the overlapping packaging material edge regions at the point of connection. According to another variant of the wrapping package according to the invention, instead of a hot-melt adhesive coating 15, a permanent adhesive coating 15 '(pressure-sensitive adhesive layer) is applied over the entire surface to connect the pre-composite 7 and the OPP film 13, which is revealed in the cutout 6 . The use of permanent adhesive layers on the surface of packaging materials, which are supplied to the packer in particular in the form of a roll on rolls, is generally not common, since adjacent layers of the packaging material can bond to one another at the points of the permanent adhesive coating, that is to say as one can expresses, the material in the role "blocks". Surprisingly, this is not the case here: possibly because there are spaces between the permanent adhesive coating 15 'within the cutouts 6 and the underlying packaging material layer in the roll with a thickness equal to that of the pre-composite 7. When connecting the two envelope folds 10, 11 during the packaging process, however, this intermediate space is bridged by pressing a pressure stamp with a small-area printing area at the location of the cutout 6, and the adhesive is made to the surface of the envelope fold below.
