Description

Vorliegende Erfindung betrifft ein Deckelmaterial aus einem Trägermaterial, einem, bezogen auf einen Behälter an dem das Deckelmaterial angewendet wird, nach aussen weisenden Bedruckung und einer nach innen weisenden Siegelschicht, zum Verschliessen von Behältern mit einem Schulterbereich.The present invention relates to a cover material made from a carrier material, one on a container to which the lid material is applied, outward-facing printing and an inward-facing sealing layer, for closing containers with a shoulder area.

Es ist bekannt, Behälter, wie beispielsweise tief- oder streckgezogene Behälter oder anderweitig geformte Behälter, an deren Öffnung mit einer ebenen ringförmigen Schulter zu versehen und solche Behälter, insbesondere nach dem Befüllen, zu bedeckeln, wobei der Deckel vollflächig auf der Schulter aufliegt und beispielsweise durch Siegeln oder Kleben an der Schulter trennfest und dichtend befestigt wird. Solche Becher, Schalen, Menuschalen, beispielsweise mit einem oder mehreren Fächern, Gobelets, Kleinverpackungen usw. sind beispielsweise bekannt zum Verpacken von Nahrungsmitteln aller Art, wie z.B. Milchprodukte, insbesondere Joghurt, Schlagsahne, Sauermilch, Sauerrahm, Kaffeesahne, Fertigzubereitungen von Salaten oder Halb- oder Vollkonserven, vorgekochten oder anderweitig vorbereiteten Gerichten, Getränke, wie Frucht- und Gemüsesäfte, Trinkwasser usw.It is known to use containers, such as deep-drawn or stretch-drawn containers, or otherwise molded containers to be provided with a flat annular shoulder at the opening and to cover such containers, especially after filling, the lid lies completely on the shoulder and, for example, by sealing or gluing to the Shoulder is fixed and sealed. Such cups, bowls, menu bowls, for example with one or more compartments, tapestries, small packaging, etc. are for example known for packaging all kinds of food, e.g. Dairy products, in particular yogurt, whipped cream, sour milk, sour cream, coffee cream, ready-made preparations of salads or half or full preserves, pre-cooked or otherwise prepared Dishes, drinks such as fruit and vegetable juices, drinking water etc.

In der Regel werden die Behälter beffült und das Deckelmaterial wird von der Rolle endlos über die zu bedeckelnden Behälter, die kontinuierlich in einer Verpackungsmaschine zulaufen, bedeckelt. Das mit einer Siegelschicht versehene Deckelmaterial wird mittels eines Siegelwerkzeuges im Schulterbereich des Behälters auf den Behälterrand aufgesiegelt. Anschliessend wird beispielsweise mittels eines Stanzwerkzeuges oder Messers das Deckelmaterial aufgetrennt und die befüllten und bedeckelten Behälter vereinzelt, resp. in Gruppen vereinzelt und abgepackt und dem Handel zugeführt.As a rule, the containers are filled and the lid material becomes endless from the roll about the containers to be covered, which run continuously in a packaging machine, covered. The lid material provided with a sealing layer is made using a sealing tool sealed onto the edge of the container in the shoulder area of the container. Subsequently the lid material is, for example, by means of a punch or knife separated and the filled and covered containers isolated, resp. in groups isolated and packaged and brought to the trade.

Das Deckelmaterial kann aus verschiedensten Materialien, je nach den gestellten Anforderungen, sein. Typische Beispiele sind Metallfolien die ein- oder beidseitig mit Kunststoff beschichtet sind. Andere Deckelmaterialien sind thermoplastische Kunststoffe, als Monofolie oder als Mehrschichtlaminat. Weitere Deckelmaterialien können aus cellulosehaltigen Materialien, wie Zellglas oder Papier sein. Um das Deckelmaterial mit dem Behälterrand zu versiegeln wird das Deckelmaterial vollflächig mit einer Siegelschicht, wie einem Siegellack oder einer Siegelfolie versehen, wobei die Siegelschicht beispielsweise auf beiden Seiten des Deckelmaterials oder wenigstens auf der, an der fertigen Verpackung nach innen weisenden Seite, d.h. gegen den Behälterinnenraum weisend, angebracht ist. The lid material can be made of different materials, depending on the requirements, be. Typical examples are metal foils coated on one or both sides with plastic are. Other lid materials are thermoplastics than monofilm or as a multilayer laminate. Other lid materials can be made from cellulosic materials, like cellophane or paper. To seal the lid material with the edge of the container the cover material is covered over the entire surface with a sealing layer, such as sealing wax or provided a sealing film, the sealing layer for example on both sides of the Lid material or at least on the inside of the finished packaging Side, i.e. pointing towards the interior of the container.

Das Deckelmaterial dient im weiteren als Informations- und Werbeträger. Aus diesem Grunde wird das Deckelmaterial auf seiner Aussenseite mit einem Druck- oder Konterdruck versehen. Die Bedruckung kann auf der obersten, an einem fertigen Behälter nach aussen weisenden Schicht, angeordnet sein. Die Bedruckung kann auch mit einem Schutzlack oder mit einer Schutzfolie abgedeckt sein oder die oberste oder die obersten Schichten des Deckelmaterials können aus transparenten oder opaken Materialien sein und einen Konterdruck aufweisen. Die Druckbilder können ein- oder mehrfarbig sein und in einem Druckwerk aufgebracht werden.The lid material also serves as an information and advertising medium. For this reason the lid material is provided with a print or counter print on the outside. The printing can be on the top, facing outwards on a finished container Layer. The printing can also be done with a protective varnish or with be covered with a protective film or the top or the top layers of the cover material can be made of transparent or opaque materials and have a counter print. The printed images can be single or multi-colored and applied in a printing unit will.

Das Deckelmaterial wird beispielsweise derart hergestellt, dass ein Träger, wie eine Metallfolie, eine Kunststoffolie oder ein Kunststoffolienverbund durch Kaschieren oder Kalandrieren mit einer oder mehreren weiteren Schichten zu einem Mehrschichtverbund verarbeitet wird. Auf der am fertigen Behälter nach innen weisenden Seite des Deckelmaterials wird durch Lackieren oder Kaschieren die Siegelschicht aufgebracht. Nach diesen Verarbeitungsschritten wird das beispielsweise als Rollenware vorliegende Deckelmaterial durch ein Druckwerk geleitet. Auf der später am Behälter nach aussen weisenden Seite des Deckelmaterials kann anschliessend noch eine Bedruckung angebracht werden.The lid material is produced, for example, in such a way that a carrier, such as a metal foil, a plastic film or a plastic film composite by lamination or Calendering with one or more additional layers processed to a multi-layer composite becomes. On the side of the lid material facing the inside of the finished container the sealing layer is applied by painting or laminating. After these processing steps the lid material, for example in roll form, is replaced by a Printing unit directed. On the side of the lid material that later points outwards on the container can then be printed.

Nachteilig bei diesen bekannten Verfahren zur Herstellung von Deckelmaterialien sind die Vielzahl von Verarbeitungsschritten und insbesondere an den Deckelmaterialien der hohe Materialaufwand für die vollflächige Bedeckung des Deckelmaterials mit siegelfähigem Material, obwohl nur ein geringer Prozentsatz dieses siegelfähigen Material letztentlich für die Siegelnaht gebraucht wird.The disadvantage of these known methods for the production of lid materials are Variety of processing steps and especially the high lid materials Cost of materials for covering the entire lid material with sealable material, although only a small percentage of this sealable material is ultimately for the Sealing seam is needed.

The substrate can be printed with all known printing processes, e.g. Book, offset, flexo, screen, Helio and copper intaglio printing. The choice of which printing process is used depends on the desired print quality, on the respective technical conditions and the number of copies. Flexographic printing (also called aniline or rubber printing) is preferred and rotogravure, such as copper gravure, or helio printing. The printing on the The outside of the carrier material can, for example, additionally by means of a protective lacquer can be painted over or by means of a laminating aid or an adhesive, a transparent Film, for example made of polyethylene terephthalate, polyamide, polyolefins, such as polyethylene or polypropylene or a cellophane layer.

Auf der an einem fertigen Behälter zur Behälterinnenseite weisenden Seite des Deckelmaterials ist eine Siegelschicht angebracht. Die Siegelschicht ist in Form eines Druckbildes auf dem Trägermaterial angebracht. Die Siegelschicht kann im gleichen oder einem vorangestellten oder hintennachgestellten Druckwerk,in dem das aussenseitige Druckbild erzeugt wird, auf das Trägermaterial aufgebracht werden. Die Siegelschicht kann vorteilhaft aus einem Primer und/oder Haftvermittler und einem Siegellack sein oder kann nur aus einem Siegellack sein. Bevorzugt ist die Anwendung eines Primers oder Haftvermittlers und eines Siegellackes. Der Haftvermittler, resp. der Primer und der Siegellack werden nacheinander in einem Druckwerk, beispielsweise durch einen Buch-, Offset-, Flexo-, Sieb-, Helio-, Tief- oder Kupfertiefdruck, vorzugsweise durch einen Flexo- oder Heliodruck, auf das Trägermaterial aufgebracht.On the side of the lid material facing the inside of a finished container a sealing layer is attached. The sealing layer is in the form of a printed image attached to the carrier material. The sealing layer can be the same or a prefix or rear-facing printing unit in which the outside print image is generated, be applied to the carrier material. The sealing layer can advantageously consist of one Primer and / or adhesion promoter and a sealing wax or can only consist of a sealing wax be. The use of a primer or adhesion promoter and a sealing wax is preferred. The adhesion promoter, resp. the primer and the sealing wax are successively in one Printing unit, for example by a book, offset, flexo, screen, helio, deep or Copper gravure printing, preferably by flexographic or helio printing, on the carrier material upset.

Die Siegelschicht kann einen Siegellack, beispielsweise aus der Reihe der Polyolefine und vorzugsweise Polyethylene, oder der Vinylacrylcopolymere oder der acrylpolymerhaltigen Lacke oder der Epoxydlacke, enthalten oder daraus bestehen.

Das Verfahren wird derart ausgeführt, dass die nach innen weisende Siegelschicht mittels eines Druckverfahrens auf dem Trägermaterial angebracht wird, wobei das Druckbild dem Schulterbereich des Behälters entspricht.The method is carried out in such a way that the inward-facing sealing layer by means of a Printing method is attached to the carrier material, the print image to the Shoulder area of the container corresponds.

Bevorzugt ist ein Verfahren zur Herstellung von Deckelmaterial nach vorliegender Erfindung bei dem die nach innen weisende Siegelschicht und die nach aussen weisende Bedruckung in einem Druckwerk durch beidseitiges Bedrucken des Deckelmaterials aufgebracht werden. A method for producing cover material according to the present invention is preferred where the inward-facing sealing layer and the outward-facing printing in be applied to a printing unit by printing the cover material on both sides.

Vorliegende Erfindung betrifft auch die Verwendung von Deckelmaterial aus einem Trägermaterial mit, bezogen auf einen Behälter an dem das Deckelmaterial angewendet wird, nach aussen weisender Bedruckung und einer nach innen weisenden Siegelschicht, wobei die nach innen weisende Siegelschicht in Form eines Druckbildes, das dem Schulterbereich des Behälters entspricht, auf dem Trägermaterial angebracht ist und das Druckbild dem Schulterbereich eines Behälters entspricht, zum Verschliessen durch Versiegeln des Behälters mit dem entsprechenden Schulterbereich.The present invention also relates to the use of cover material made of a carrier material with, based on a container to which the lid material is applied, after outside-facing printing and an inward-facing sealing layer, whereby the sealing layer on the inside in the form of a printed image that covers the shoulder area of the container corresponds, is attached to the carrier material and the printed image on the shoulder area corresponds to a container, for closing by sealing the container with the corresponding shoulder area.

Die Figur 1 zeigt beispielhaft und schematisch einen Becher 1 aus Seitenwand 2, Boden 3 und oberem Randabschluss, welcher die Schulter 4 bildet Nach dem Befüllen des Bechers 1 beispielsweise mit einem Nahrungsmittel oder einem Getränk, wie Joghurt, Marmelade, Trockenfrüchten, einer Schokoladenzubereitung oder einem anderen Dessert oder mit Trinkwasser oder Frucht- und Gemüsesäften, wird der Becher 1 mit dem Deckel 10 bedeckt und der Deckel 10 entlang der Schulter 4 auf den Becher 1 aufgesiegelt. Der Deckel 10 enthält ein Trägermaterial 5, darauf angebracht ein Druck 6 und eine Schutzschicht 7, beispielsweise in Form eines Schutzlackes oder einer Schutzfolie. Auf der gegen den Behälter, resp. die Behälterinnenseite, gerichteten Seite des Trägermaterials 5 ist im Bereich der Schulter 4 des Behälters 1 die Siegelschicht aus Primer 8 und Siegellack 9 nur stellenweise aufgetragen, nämlich entsprechend oder annähernd entsprechend dem Abbild der ringförmigen Schulter 4 des Bechers 1. An dem Deckel 10 ist die Siegelschicht aus Primer 8 und Siegellack 9 demnach nur oder im wesentlichen nur an jenen Stellen auf dem Träger 5 aufgetragen, welche mit der Schulter 4 in Berührung gelangen. Dies ist durch die strichpunktierten Linien schematisch angedeutet. Für das vorliegende Beispiel würde dies bedeuten, dass die Siegelschicht 8,9 ringförmig auf dem Träger 5 aufgedruckt worden ist. Es ist selbstverständlich, dass das Druckbild der Siegelschicht vom Schulterbereich 4 des Bechers 1 leicht abweichen kann. Beispielsweise bei einer sehr breiten Schulter 4 kann das Druckbild der Siegelschicht 8,9 schmaler sein, z.B. 1 bis 50 % schmaler, als die Breite der Schulter des Behälters 4, oder, um Maschinenungenauigkeiten auszugleichen, kann die Fläche des Druckbildes der Siegelschicht 8,9 um einige Prozente, wie 1 bis 25 %, grösser gewählt werden, als die Berührungsfläche zwischen Deckelmaterial und Schulterbereich 4.FIG. 1 shows, by way of example and schematically, a cup 1 made from side wall 2, bottom 3 and the upper edge, which forms the shoulder 4, after the cup 1 has been filled for example with a food or a drink, such as yogurt, jam, Dried fruit, a chocolate preparation or another dessert or with Drinking water or fruit and vegetable juices, the cup 1 is covered with the lid 10 and the lid 10 is sealed onto the cup 1 along the shoulder 4. The lid 10 contains a carrier material 5, thereon a print 6 and a protective layer 7, for example in the form of a protective varnish or a protective film. On the against the container, respectively. the inside of the container, the facing side of the carrier material 5 is in the region of the shoulder 4 of the container 1, the sealing layer of primer 8 and sealing wax 9 only applied in places, namely, according to or approximately according to the image of the annular shoulder 4 of the cup 1. On the lid 10 is the sealing layer of primer 8 and sealing wax 9 accordingly applied only or essentially only at those locations on the carrier 5 which come into contact with shoulder 4. This is shown schematically by the dash-dotted lines indicated. For the present example, this would mean that the sealing layer 8,9 has been printed in a ring on the carrier 5. It goes without saying that that Print image of the sealing layer from the shoulder area 4 of the cup 1 may differ slightly. For example, with a very wide shoulder 4, the printed image of the sealing layer 8.9 be narrower, e.g. 1 to 50% narrower than the width of the shoulder of the container 4, or, um Compensating for machine inaccuracies can affect the area of the printed image of the sealing layer 8.9 by a few percent, such as 1 to 25%, larger than the contact area between cover material and shoulder area 4.

Das vorliegende Deckelmaterial kann über die Siegelschicht auf den Behälterrand aufgesiegelt werden. Durch die Wähl des Siegelwerkzeuges, den Siegeldruck und die Siegeltemperatur kann die Festigkeit der Seigelnaht eingestellt werden. An der Siegelnäht können auch Anreisshilfen, beispielsweise in Form von schwächer gesiegelten Teilbereichen in der Siegelnaht oder durch zackenförmige Siegelnahtkanten, angebracht werden. Anstelle der aufgedruckten Siegelschicht kann auch eine Verklebung mit einem Klebstoff, wie einem Kontaktklebstoff oder einem unter Wärme und/oder Druck abbindenden Klebstoff, angewendet werden. Dies mit der Massgabe, dass der Klebstoff sich in einem Druckwerk verarbeiten lässt und der Klebstoff auf das Deckelmaterial aufgedruckt werden kann.The present lid material can be sealed onto the edge of the container via the sealing layer will. By choosing the sealing tool, the sealing pressure and the sealing temperature the strength of the sea seam can be adjusted. Scribing aids can also be attached to the sealed seam, for example in the form of weakly sealed sections in the sealed seam or by serrated sealing seam edges. Instead of the printed one Sealant layer can also be glued with an adhesive, such as a contact adhesive or an adhesive that sets under heat and / or pressure. This with the proviso that the adhesive can be processed in a printing unit and the Adhesive can be printed on the lid material.

Vorliegendes Deckelmaterial hat den Vorteil, mit den Ausgangsmaterialien äusserst sparsam umzugehen, insbesondere dadurch, das Primer oder Haftvermittler und Siegellack nur spärlich an den Stellen angewendet wird, wo diese tatsächlich benötigt werden. Typischerweise wird der Primer oder Haftvermittler in Mengen von 0,2 bis 30 g, vorzugsweise 3 bis 20 g, pro Quadratmeter und der Siegellack in Mengen von 0,5 bis 30 g, vorzugsweise 1,5 bis 20 g, pro Quadratmeter und insbesondere jeweils mit 6 bis 10 g pro Quadratmeter angewendet. Da der Primer, resp. Haftvermittler und der Siegellack in der Regel zur Verarbeitung in der Druckmaschine in einem Lösungsmittel aufgenommen sein muss, reduziert sich die Menge am zu verdampfenden Lösungsmittel erheblich. Dies drückt sich sowohl im Energiebedarf als auch in der anfallenden Lösungsmittelmenge aus. Das vorliegende Verfahren ist im weiteren deshalb vorteilhaft, weil die Herstellung des Deckelmaterials einen Maschinengang weniger benötigt. Die Siegelschicht muss nicht separat als Schicht oder Folie aufgetragen werden, sondern kann beim Anbringen des Druckbildes im gleichen Arbeitsgang und fallweise im gleichen Druckwerk, aufgebracht werden.The present cover material has the advantage of being extremely economical with the starting materials to deal with, especially by using the primer or adhesion promoter and sealing wax only sparingly is used where it is actually needed. Typically the primer or coupling agent is used in amounts of 0.2 to 30 g, preferably 3 to 20 g, per square meter and the sealing wax in quantities of 0.5 to 30 g, preferably 1.5 to 20 g, per square meter and in particular applied with 6 to 10 g per square meter. There the primer, resp. Adhesion promoter and the sealing wax usually for processing in the Printing machine must be absorbed in a solvent, the amount is reduced on the solvent to be evaporated considerably. This is expressed both in energy requirements and also in the amount of solvent. The present procedure is further below advantageous because the production of the lid material is one machine less needed. The sealing layer does not have to be applied separately as a layer or film, but can be applied in the same operation and occasionally in the application of the printed image same printing unit, can be applied.

Vorliegende Erfindung kann sowohl an Rollenware oder endlosem Material oder an vereinzelten Deckein verwirklicht werden, wobei das Aufbringen der Siegelschicht an Endlosmaterial erfolgen kann und die Deckel durch Stanzen oder Schneiden vereinzelt und verarbeitet werden können oder aus endlosem Deckelmaterial können Einzeldeckel ausgestanzt oder ausgeschnitten und anschliessend kann die Siegelschicht an diesen Einzeldeckeln aufgedruckt werden. Für eine maschinelle Bedruckung können die Einzeldeckel beispielsweise für den Druckvorgang auf einem endlosen Trägerband haftend angeordnet sein. Die fertigen Deckel können im weiteren eine Aufreiss- oder Grifflasche und/oder Schwächungen, beispielsweise in Form von Perforationen oder Anreisskerben, aufweisen, welche das Öffnen des Behälters durch Entfernen des Deckels erleichtern.The present invention can be either on roll goods or endless material or on isolated Covers can be realized, the application of the sealing layer to continuous material can be done and the lid isolated by punching or cutting and processed can be or single covers can be punched out or made of endless cover material cut out and then the sealing layer can be printed on these individual lids will. For machine printing, the individual covers can be used, for example, for the Printing process to be arranged adhering to an endless carrier tape. The finished lids can further include a tear-open or grip tab and / or weakenings, for example in the form of perforations or marking notches, which open the container by removing the lid.

Da die Siegelschicht am Deckel im wesentlichen nur im Schulterbereich des gegenüberliegenden Behälters vorhanden ist, wird auch die Gefahr minimiert, dass Bestandteile aus der Siegelschicht in den Behälterinhalt diffundieren und beispielsweise dem Behälterinhalt durch Geruchs- oder Geschmacksstoffe beeinflussen.Since the sealing layer on the lid essentially only in the shoulder area of the opposite Container is present, the risk that components from the Diffuse the sealing layer into the contents of the container and, for example, through the contents of the container Affect odors or flavors.

Vorliegende Erfindung ermöglicht es, auch vollkommen transparente oder nahezu vollkommen transparente Deckelmaterialien zu schaffen, indem der Siegellack nur an den Stellen der Siegelung und nicht über den gesamten Deckelbereich aufgetragen ist und die Eigenschaften eines völlig transparenten Trägermaterials voll erhalten bleiben. Die transparenten Trägermaterialien verschlechtern sich bezüglich ihrer Durchsichtigkeit durch den Siegellack und den Primer nicht.The present invention also makes it possible to be completely transparent or almost completely to create transparent cover materials by using the sealing wax only at the points of the Seal and not applied over the entire lid area and the properties of a completely transparent carrier material. The transparent carrier materials deteriorate in their transparency by the sealing wax and the Not primer.
