Abstract

The invention relates to the embossing of a foil material with printing marks and pre-sized cover members for food containers (26), said embossing being partly carried out by means of sensors and by means of the regulated tensile force of embossing drums. Said partially embossed cover members (24) comprise a smooth surface area (24b) in the region of the container flange (27) and they are embossed in the rest of the surface area. The surface side (24') facing the container (26) can comprise a heat-sealable coating (25), preferably in the region of the width of the container flange (27). The heat-sealable coating (25') can also be applied in the embossed area (24'), so that the entire area (24') of the cover member is covered with a heat-sealable varnish. Partial embossing of the inventive cover members makes the food containers easy to use by the consumer and their embossed area (24a) also allows for satisfying stacking of said containers at the time of storage.

Description

Verfahren zur Herstellung von teilweise geprägten Deckelelementen für Behälter Process for the production of partially embossed lid elements for containers
Die Erfindung betrifft ein Verfahren zur Herstellung von teilweise geprägten Deckelelementen für den Verschluß von Behältern, insbesondere Nahrungsmittelbehältern, eine Vorrichtung zur Durchführung dieses Verfahrens sowie nach diesem Verfahren hergestellte, teilweise geprägte Deckelelemente.The invention relates to a method for producing partially embossed cover elements for the closure of containers, in particular food containers, to a device for carrying out this method and to partially embossed cover elements produced by this method.
Stand der TechnikState of the art
Deckelelemente für Behälter, beispielsweise für Joghurtbecher werden u.a. durch Ausstanzen von bedruckten Aluminiumfolien hergestellt. Zum luftdichten Verschließen weisen diese Folien an der nicht bedruckten Seite eine Heißsiegellackschicht auf. Nach dem Ausstanzen in die gewünschte Deckelform werden diese in einem Stapel gelagert. Zu deren Weiterverwendung müssen sie bei- spielsweise mit Saugnäpfen vom Stapel abgehoben werden. Um zu verhindern, daß beim Abheben mehrere Deckel aneinanderhaften, weil sich zwischen ihnen keine Luftschicht befindet, sind die Deckel mit einer Prägung versehen. Diese Prägung erfolgt zumeist an der bedruckten Folie, bevor die Deckelelemente ausgestanzt werden.Der Prägevorgang hat jedoch den Nachteil, daß das Druckbild verzerrt oder sogar zerstört wird.Lid elements for containers, for example for yoghurt pots, are among others produced by punching out printed aluminum foils. For airtight sealing, these foils have a heat seal lacquer layer on the unprinted side. After punching out the desired lid shape, they are stored in a stack. For further use, they have to be lifted off the stack, for example with suction cups. In order to prevent several lids from sticking together when lifting because there is no air layer between them, the lids are embossed. This stamping is usually done on the printed film before the cover elements are punched out. However, the stamping process has the disadvantage that the printed image is distorted or even destroyed.
Gemäß der FR-A-2 731 986 werden daher Deckelelemente vorgeschlagen, welche neben einem geprägten auch einen ungeprägten Ober- flächenbereich aufweisen. Dieser ungeprägte Oberflächenbereich weist jenen Aufdruck auf, welcher eine für den Verbraucher wesentliche Information, wie Ablaufdatum oder Lebensmittelinhaltsstoffe, darstellt und daher gut lesbar sein muß.According to FR-A-2 731 986, cover elements are therefore proposed which, in addition to an embossed surface area, also have an unembossed surface area. This non-embossed surface area has the imprint which represents information that is essential for the consumer, such as expiry date or food ingredients, and must therefore be legible.
Diese Deckelelemente werden aus bedruckten und anschließend geprägten Folien hergestellt. Für die Ausbildung des ungeprägten Bereiches werden entsprechened geformte Preßwerkzeuge eingesetzt. Diese werden mit hohem Anpreßdruck an die geprägte Folie gepreßt, sodaß der ungeprägte Oberflächenbereich erzeugt wird. Dieses Verfahren ist nun deshalb aufwendig, da die Prägung mit zusätzlichen Werkzeugen rückgängig gemacht werden muß. Dennoch verbleibt eine Restprägung, sodaß der Aufdruck verzerrt und somit die Lesbarkeit weiterhin beschwerlich ist.These cover elements are made from printed and then embossed foils. Correspondingly shaped pressing tools are used to form the unembossed area. These are pressed onto the embossed film with high contact pressure, so that the unembossed surface area is created. This process is now complex because the embossing must be reversed with additional tools. Nevertheless, there is a remaining embossing, so that the print is distorted and legibility remains difficult.
Darstellung der ErfindungPresentation of the invention
Aufgabe der Erfindung ist es daher, ein Verfahren der eingangs genannten Art anzugeben, welches einerseits leicht durchführbar ist und wodurch andererseits teilweise geprägte Deckelelemente in Verbraucher-freundlicher Form erzeugt werden.It is therefore an object of the invention to provide a method of the type mentioned at the outset, which on the one hand is easy to carry out and on the other hand partially embossed cover elements are produced in a consumer-friendly form.
Dieses Verfahren ist erfindungsgemäß dadurch gekennzeichnet, daß ein Folienmaterial 1, an welchem über Druckmarken 5 die Abstände Y zwischen den vordimensionierten Deckelementen 2 mittels eines Sensors 8 lesbar sind, zwischen zwei Prägewalzen 11 bzw. 11' und 12 bzw. 12' geführt wird, welche neben einem glatten Oberflä- chenbereich ebenso einen Prägebereich aufweisen und deren Winkelposition vom Sensor 13 ermittelt wird, daß nach Vergleich der durch die Sensoren 8 und 13 ermittelten Werte durch den Regler 9 für den Fall der Identität dieser Werte das teilweise geprägte Folienmaterial 15 hergestellt wird, welches über Umlenkrollen einem Stanzwerkzeug zugeführt wird, an dem die teilweise geprägten Deckelelemente erzeugt werden.According to the invention, this method is characterized in that a film material 1, on which the distances Y between the pre-dimensioned cover elements 2 can be read by means of a sensor 8, is guided between two embossing rollers 11 and 11 'and 12 and 12', respectively in addition to a smooth surface area also have an embossing area and the angular position of which is determined by the sensor 13, that after comparing the values determined by the sensors 8 and 13, the controller 9 produces the partially embossed film material 15 in the event that these values are identical, which is fed via deflection rollers to a punching tool on which the partially embossed cover elements are produced.
Ein weiterer Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß bei Nicht-Identität der Sensoren 8 und 13 ermittelten Werte diese Diskrepanz vom Regler 9 an den Motor 7 weitergeleitet wird, sodaß das Drehmoment der AbwickelVorrichtung 6 vermindert oder erhöht, die Geschwindigkeit der Prägewalzen 11, 12 jedoch konstant gehalten wird, und daß durch diese erzeugte Zugkraft das Folienmaterial 1 um den an den Druckmarken 5 gemessenen Wert X gedehnt wird, sodaß Identität der an den Sensor 8 und 13 ermittelten Werte vorliegt und der geprägte bzw. ungeprägte Oberflächenbereich dimensionsgerecht innerhalb der Druckmarken 5 erzeugt wird.

Die Erfindung wird nun anhand von Ausführungsbeispielen näher erläutert:The invention will now be explained in more detail on the basis of exemplary embodiments:
In einer Ausführungsform weist das Folienmaterial 1 die vordimensionierten Deckelelemente 2 auf. Diese können derart bedruckt sein, daß für den geprägten Bereich der Aufdruck 3 und für den ungeprägten Bereich der Aufdruck 4, beispielsweise in Form einer für den Verbraucher wichtigen Beschriftung, vorgesehen sind. Zur Markierung des Abstandes zwischen den einzelnen Deckelelementabschnitten 2 sind auf dem Folienmaterial 1 die Druckmarken 5 vorgesehen. Das Folienmaterial 1 kann beispielsweise Kunststoff oder Aluminium mit einer Zugfestigkeit von 50 bis 130 N/mm sein. Es ist jedoch auch möglich, Verbundmaterialien hoher Zugfestigkeit einzusetzen, wobei aus folgenden Materialkombinationen ausgewählt werden kann: Aluminium/Aluminium, Aluminium/Kunststoff, Aluminium/Papier, Aluminium/Papier/Kunststoff, Kunststoff/Kunststoff, Kunststoff/Papier, Aluminium/Papier/Aluminium, Aluminium/Kunststoff/Aluminium.In one embodiment, the film material 1 has the pre-dimensioned cover elements 2. These can be printed in such a way that the print 3 for the embossed area and the print 4 for the unembossed area, for example in the form of an inscription important for the consumer, are provided. To mark the distance between the individual cover element sections 2, the printing marks 5 are provided on the film material 1. The film material 1 can be, for example, plastic or aluminum with a tensile strength of 50 to 130 N / mm. However, it is also possible to use composite materials with high tensile strength, whereby the following material combinations can be selected: aluminum / aluminum, aluminum / plastic, aluminum / paper, aluminum / paper / plastic, plastic / plastic, plastic / paper, aluminum / paper / aluminum , Aluminum / plastic / aluminum.
Das Folienmaterial 1 wird nun entsprechend der Geschwindigkeit des Motors 7 von der Vorrichtung 6 abgewickelt und passiert den Sensor 8. Dieser ermittelt in Längsrichtung den Abstand Y der Druckmarken 5 (siehe Fig. 2) und gibt diesen Wert an den Regler 9 weiter. Anschließend wird die Folie 1 in die Prägestation 10, geführt, welche aus den Prägewalzen 11 und 12 besteht. Diese weisen an ihrer Oberflächen die Prägebereiche 11a, 12a sowie die glatten Bereiche 11b, 12b, durch welchen der ungeprägte Deckelbereich ausgebildet wird, auf. Die Winkelposition der Prägewalzen 11,12 wird mittels des Sensors 13 festgestellt und ebenso an den Regler 9 weitergeleitet. Der Regler 9 vergleicht die ermittelten Werte. Ergeben diese eine Übereinstimmung, so ist es gewährleistet, daß zwischen zwei Druckmarken 5 entsprechend den Prägewalzenoberflächen 11a und 11b bzw. 12a und 12b ein Deckelelement 14 mit geprägtem bzw. passergenau ungeprägtem Oberflächenbereichen 14a bzw. 14b entsteht.The film material 1 is now unwound from the device 6 in accordance with the speed of the motor 7 and passes the sensor 8. This determines the distance Y of the printing marks 5 in the longitudinal direction (see FIG. 2) and passes this value on to the controller 9. The film 1 is then guided into the embossing station 10, which consists of the embossing rollers 11 and 12. These have on their surfaces the embossed areas 11a, 12a and the smooth areas 11b, 12b, through which the unembossed lid area is formed. The angular position of the embossing rollers 11, 12 is determined by means of the sensor 13 and also passed on to the controller 9. The controller 9 compares the determined values. If they match, it is ensured that between two printing marks 5 corresponding to the embossing roller surfaces 11a and 11b or 12a and 12b, a cover element 14 with embossed or register-accurate, unembossed surface areas 14a or 14b is created.
Sind diese Werte jedoch voneinander abweichend, so wird die Differenz ermittelt und durch den Regler 9 an den Motor 7 weiter- gegeben. Wird das Drehmoment des Motors 7 entsprechend der ermittelten Differenz reduziert, die Drehgeschwindigkeit der Prägewalzen 11 und 12 jedoch beibehalten, so wird eine Zugkraft auf die Folienbahn 1 ausgeübt und das Material auf den gewünschten Druckmarkenabstand X gedehnt (siehe Fig.2).However, if these values differ from one another, the difference is determined and passed on to the motor 7 by the controller 9. If the torque of the motor 7 is reduced in accordance with the determined difference, but the rotational speed of the embossing rollers 11 and 12 is maintained, then a tensile force is exerted on the film web 1 and the material is stretched to the desired mark distance X (see FIG. 2).
Anschließend wird die teilweise geprägte Folie 15 über mehrere Umlenkwalzen 16, 17, 18, 19 und 20 dem Vorschubwalzenpaar 21 zugeführt, welches durch den Leser 22 gesteuert wird. Durch das Stanzwerkzeug 23 werden die endgefertigten Deckelelemente 14 in die gewünschte Form gestanzt und gestapelt. Die endgefertigten Deckelelemente 14 weisen einen geprägten Bereich 14a und den ungeprägten Bereich 14b auf. Eventuelle Be- schriftungen, die für den Konsumenten wesentlich sind, sind im ungeprägten Bereich 14b angebracht und weisen eine zufriedenstellende Lesbarkeit auf.The partially embossed film 15 is then fed via a plurality of deflection rollers 16, 17, 18, 19 and 20 to the feed roller pair 21, which is controlled by the reader 22. The finished cover elements 14 are punched and stacked into the desired shape by the punching tool 23. The finished cover elements 14 have an embossed area 14a and the unembossed area 14b. Any inscriptions that are essential for the consumer are affixed in the unembossed area 14b and have a satisfactory readability.
In einer weiteren Ausführungsform werden die teilweise geprägten Deckelelemente 24 erzeugt. Daher weist das Folienmaterial 1 ebenso die vordimensionierten Deckelelemente 2 auf nur mit dem Unterschied, daß eine heißsiegelnde Beschichtung 25, 25' beispielsweise in Form eines Heißsiegellackes vorgesehen ist. Der Aufdruck 4 kann entfallen.In a further embodiment, the partially embossed cover elements 24 are produced. Therefore, the film material 1 also has the pre-dimensioned cover elements 2 with the only difference that a heat-sealing coating 25, 25 'is provided, for example in the form of a heat-sealing lacquer. The imprint 4 can be omitted.
Ferner werden anstelle der Prägewalzen 11 und 12 die Prägewalzen 11' und 12' in der Prägestation 10 eingesetzt. Diese weisen die glatten Oberflächenbereiche 11 'b, 12 'b auf, durch welche der glatte Oberflächenbereich 24b erzeugt wird. Durch die Prägebereichw 11 'a, 12 'a wird der geprägte Bereich 24a erzeugt.Furthermore, the embossing rollers 11 ′ and 12 ′ are used in the embossing station 10 instead of the embossing rollers 11 and 12. These have the smooth surface areas 11 'b, 12' b, by means of which the smooth surface area 24b is produced. The embossed area 24a is produced by the embossed area w 11'a, 12'a.
Der glatte Oberflächenbereich 24b kann dabei in seiner Breite dem Flansch 27 des Nahrungsmittelbehalters 26 entsprechen und weist vorzugsweise die heißsiegelnde Beschichtung 25 auf. Es ist jedoch ebenso möglich, die heißsiegelnde Beschichtung 25' zusätzlich im geprägten Bereich aufzutragen, sodaß das Deckelelement insgesamt an seiner Oberfläche 24' mit Heißsiegellack versehen ist.The width of the smooth surface area 24b can correspond to the flange 27 of the food container 26 and preferably has the heat-sealing coating 25. However, it is also possible to additionally apply the heat-sealing coating 25 'in the embossed area, so that the cover element as a whole is provided with heat-sealing lacquer on its surface 24'.
Die weitere Verfahrensführung entspricht der vorgenannten Ausführungsform.The further procedure corresponds to the aforementioned embodiment.
Die Deckelelemente 24 sind nun - bedingt durch den stark ausgebildeten geprägten Bereich 24a - leicht entstapelbar. Sie sind jedoch insoferne Verbraucher-freundlich, da sie sich leicht vom Flansch 27 des Nahrungsmittelbehalters 26 abziehen lassen. Dies wird durch die glatte Oberfläche im Bereich 24b, in welchem vorzugsweise die heißsiegelnde Beschichtung 25 vorgesehen ist, bewirkt. Gewerbliche AnwendbarkeitThe cover elements 24 can now be easily unstacked, owing to the strongly formed embossed area 24a. However, they are consumer-friendly in that they can be easily pulled off the flange 27 of the food container 26. This is brought about by the smooth surface in the area 24b, in which the heat-sealing coating 25 is preferably provided. Industrial applicability
Die durch das erfindungsgemäße Verfahren hergestellten, teilweise geprägten Deckelelemente sind besonders Verbraucherfreundlich, da sie sich leicht vom Nahrungsmittelbehälter abziehen lassen oder aber für den Verbraucher gut lesbare Beschriftungen aufgrund ihrer Anordnung im ungeprägten Bereich aufwei- sen. Davon unabhängig sind sie auch gut entstapelbar bedingt durch ihren geprägten Oberflächenbereich, welcher jeweils unmittelbar an den ungeprägten Bereich anschließt. The partially embossed lid elements produced by the method according to the invention are particularly consumer-friendly, since they can be easily removed from the food container or, because of their arrangement in the non-embossed area, the labels are legible for the consumer. Regardless of this, they are also easy to unstack due to their embossed surface area, which immediately adjoins the unembossed area.
