Description

Verschlusskappe und Verfahren zum Herstellen einer Verschlusskappe Cap and method of making a cap
Beschreibungdescription
Die Erfindung betrifft eine Verschlusskappe, insbesondere Getrankeflaschenschraubverschlusskappe aus Kunststoff, mit mindestens einem an ihrer Kappenoberseite auf die Oberflache aufgetragenen Lackuberzug. Die Erfindung betrifft auch ein Verfahren zum Herstellen einer Verschlusskappe, bei dem die Veschlusskappe an ihrer Oberseite mit einem Lack überzogen wird.The invention relates to a closure cap, in particular a bottle screw cap made of plastic, with at least one lacquer coating applied to the surface of the top of the cap. The invention also relates to a method for producing a closure cap, in which the top of the closure cap is coated with a lacquer.
Es ist bekannt, dass Schraubverschlusskappen für Getrankeflaschen, nachdem sie gespritzt worden sind, dekoriert und beschriftet werden. Hierfür werden Druckverfahren verwendet, wie Trocken-Offset, indirekter Tiefdruck, Heißpragen, Flexodruck und Ink-Jet-Druck. Diese Verfahren benotigen Farben, Losemittel und Druckwerkzeuge. Die Umstellung auf neue Vorlagen ist mit einer gewissen Rüstzeit verbunden und es werden hierfür neue Druckklischees benotigt. Es ist bekannt, dass derartige Drucke ein- und mehrfarbig sein können. Die benotigten Losemittel sowie die bei der Umrüstung anfallenden Druckklischees müssen in der Regel aufwandig entsorgt werden.It is known that screw caps for beverage bottles are decorated and labeled after they have been sprayed. Printing processes such as dry offset, indirect gravure, hot stamping, flexographic printing and inkjet printing are used for this. These processes require colors, solvents and printing tools. The changeover to new templates is associated with a certain set-up time and new printing clichés are required for this. It is known that such prints can be single and multi-colored. The required solvents and the printing plates that occur during the conversion usually have to be disposed of at great expense.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Verschlusskappe sowie ein Verfahren zur Herstellung einer derartigen Verschlusskappe bereitzustellen, bei der die Umwelt weniger belastet wird, die Umrustzeit auf ein Minimum reduziert wird und die Herstellung zudem noch preiswerter Diese Aufgabe wird bei einer Verschlusskappe der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass der Lacküberzug aus einem mittels Laser abtragbaren Lack besteht und der Lacküberzug ein von einem Laser bearbeitetes Dekor bildet.The invention is therefore based on the object of providing a closure cap and a method for producing such a closure cap, in which the environment is less polluted, the changeover time is reduced to a minimum and the manufacture is also more economical This object is achieved according to the invention in the case of a closure cap of the type mentioned at the outset in that the lacquer coating consists of a lacquer which can be removed by laser and the lacquer coating forms a decor processed by a laser.
Bei der erfindungsgemäßen Verschlusskappe trägt die Kappenoberseite einen Lacküberzug, der mittels eines Lasers teilweise abgetragen ist, so dass nicht nur der Lacküberzug sondern auch ein Teil des Werkstoffes, aus welchem die Veschlusskappe hergestellt ist, sichtbar sind. Auf diese Weise kann durch entsprechendes Abtragen eines Teils des Lacküberzuges ein Dekor erzeugt werden. Dieses Dekor wird entweder von einem Bild oder von einem Schriftzug gebildet. Von der Herstellung eines derartigen Dekors ist die Markierung eines Gegenstandes mittels eines Lasers zu unterscheiden, da bei der Markierung ein hochenergetischer Laserstrahl für extrem kurze Zeit durch eine Maske hindurch auf den zu markierenden Gegenstand abgestrahlt wird. Über die Maske wird die zu markierende Information bestimmt. Mittels des Laserstrahls selbst wird also die Information bzw. das Bild nicht erzeugt, sondern mittels der Maske. Beim Dekorieren eines Gegenstandes wird keine Maske verwendet, sondern der Laserstrahl erzeugt den Bildaufbau.In the closure cap according to the invention, the top of the cap has a lacquer coating which is partially removed by means of a laser, so that not only the lacquer coating but also part of the material from which the closure cap is made are visible. In this way, a decor can be created by correspondingly removing part of the lacquer coating. This decor is either an image or a lettering. The marking of an object by means of a laser is to be distinguished from the production of such a decoration, since during the marking a high-energy laser beam is emitted for an extremely short time through a mask onto the object to be marked. The information to be marked is determined via the mask. The information or the image is therefore not generated by means of the laser beam itself, but rather by means of the mask. When decorating an object, no mask is used, but the laser beam creates the image.
Mit der erfindungsgemäßen Verschlusskappe werden keine Lösemittel und Druckklischees, Fotolacke und Ätzmittel für die Dekorierung benötigt, weshalb die Umweltbelastung gravierend verringert wird. Außerdem ist ein Umrüsten vom einen Druckbild auf ein anderes jederzeit und problemlos sowie ohne Stillstand der Produktionsanlage möglich. Die Umrüstung erfolgt seitens der Software, welche den Laser ansteuert. Dies bedeutet, dass die Verschlusskappen sogar im Random-Verfahren (Personalisierung) bearbeitet werden können.With the sealing cap according to the invention, no solvents and printing plates, photoresists and etching agents are required for the decoration, which is why the environmental impact is significantly reduced. In addition, a changeover from one print image to another is possible at any time and without any problems and without the production line being down. The conversion is carried out by the software that controls the laser. This means that the caps can even be processed in a random process (personalization).
Ein besonders bevorzugtes Einsatzgebiet sind Schraubver- Schlusskappen für Getränkeflaschen, welche auf der Oberseite in der Regel den Markennamen des Getränkeherstellers tragen.A particularly preferred area of application is screw End caps for beverage bottles, which usually bear the brand name of the beverage manufacturer on the top.
Bei einer Weiterbildung ist vorgesehen, dass auf der Kappenoberseite mehrere Lacküberzüge übereinander und/oder nebeneinander aufgetragen sind. Auf diese Weise kann problemlos ein mehrfarbiges Dekor erzeugt werden, indem ein entsprechend mehr oder weniger großer Teil des einen oder anderen Lacküberzuges abgetragen wird. Bei übereinander aufgetragenen Lackschichten können diese teilweise oder aber auch vollständig abgetragen werden. Im einen Fall kommt eine darunterliegende Lackschicht zum Vorschein, im anderen Fall wird der Grundwerkstoff der Verschlusskappe sichtbar.In a further development, it is provided that a plurality of lacquer coatings are applied one above the other and / or next to one another on the top of the cap. In this way, a multicolored decor can easily be produced by removing a correspondingly more or less large part of one or the other lacquer coating. In the case of layers of lacquer applied one above the other, these can be partially or completely removed. In one case an underlying layer of lacquer appears, in the other case the base material of the cap is visible.
Mit Vorzug ist bei übereinander aufgetragenen Lackschichten zwischen diesen eine Trennschicht vorgesehen. Diese Trennschicht ist bevorzugt farblos und durchsichtig, was den Vorteil hat, dass die darunterliegende Lackschicht geschützt wird, wenn lediglich die darüberliegende Lackschicht abgetragen wird. Sollte die darüberliegende Lackschicht eine schwankende Schichtdicke aufweisen, dann dient die Trennschicht quasi als Puffer, so dass die darunterliegende Lackschicht vom Laserstrahl nicht angegriffen wird.In the case of lacquer layers applied one above the other, a separation layer is preferably provided between them. This separating layer is preferably colorless and transparent, which has the advantage that the underlying lacquer layer is protected if only the lacquer layer above it is removed. If the lacquer layer above has a fluctuating layer thickness, the separating layer serves as a buffer, so that the lacquer layer underneath is not attacked by the laser beam.
Bei einer bevorzugten Variante weisen die Lackschicht und/oder eine Trennschicht ihr eigene Abtragungsparameter auf. Mittels moderner Lasern können aufgrund der verschiedenen Abtragungsparameter lediglich die gewünschten, abzutragenden Farbschichten abgetragen werden. Nicht abzutragende Farbschichten verbleiben aufgrund ihres oder ihrer anderen Abtragungsparameter auf der Oberseite der Verschlusskappe. So kann z.B. der eine Lack empfindlich für Licht der einen Wellenlänge und der andere Lack empfidlich für Licht der anderen Wellenlänge sein.In a preferred variant, the lacquer layer and / or a separating layer have their own removal parameters. Using modern lasers, only the desired layers of paint to be removed can be removed due to the different removal parameters. Color layers that cannot be removed remain on the top of the closure cap due to their or their other removal parameters. For example, one lacquer sensitive to light of one wavelength and the other lacquer sensitive to light of the other wavelength.
Bevorzugterweise besitzen die Lackschicht und/oder die Trennschicht eine definierte Dicke. Dann kann der Laserstrahl bzw. dessen Energie auf diese Dicke eingestellt werden, so dass lediglich diese Lackschicht entfernt wird. Das unterhalb dieser Lackschicht sich befindende Material wird vom Laserstrahl dann nicht beeinflusst.The lacquer layer and / or preferably have Interface a defined thickness. Then the laser beam or its energy can be adjusted to this thickness so that only this lacquer layer is removed. The material located below this layer of lacquer is then not affected by the laser beam.
Mit Vorzug ist die Lackschicht und/oder die Trennschicht durch einen Lackiervorgang, durch Aufdrucken, durch Aufkleben oder durch Aufsprühen aufgebracht. Auch ein Tauchvorgang ist möglich. Für diese Art des Auftrags sind keine Klischees erforderlich, da das zu erzeugende Druckbild erst später mittels des Lasers erzeugt wird. Es muss lediglich der Überzug auf die Kappenoberfläche aufgebracht werden.The lacquer layer and / or the separating layer is preferably applied by a painting process, by printing, by gluing or by spraying. Diving is also possible. No clichés are required for this type of job, since the print image to be generated is created later using the laser. Only the coating has to be applied to the cap surface.
Vorteilhaft ist die Lackschicht farbig. Auf diese Weise können nicht nur Schwarz/Weiß-Bilder sondern auch Farbbilder erzeugt werden.The varnish layer is advantageously colored. In this way, not only black and white images but also color images can be generated.
Bei einem besonders bevorzugten Ausführungsbeispiel ist die Verschlusskappe aus einem oder mehreren unterschiedlichen oder unterschiedlich farbigen Kunststoffen hergestellt. Auf diese Weise kann ein mehrfarbiger Druck sogar mit einer einzigen Lackschicht erzeugt werden.In a particularly preferred embodiment, the closure cap is made from one or more different or differently colored plastics. In this way, a multi-color print can be produced even with a single layer of lacquer.
Die oben genannte Aufgabe wird auch mit einem Verfahren zum Herstellen einer Verschlusskappe gelöst, bei dem die Verschlusskappe an ihrer Oberseite mit einem Lack überzogen wird, wobei mittels eines Lasers ein Teil des Lackes so weit und derart abgetragen wird, dass der unter der Lackschicht liegende Werkstoff sichtbar wird und ein Dekor entsteht.The above-mentioned object is also achieved with a method for producing a closure cap, in which the top of the closure cap is coated with a lacquer, part of the lacquer being removed by means of a laser to such an extent and in such a way that the material lying under the lacquer layer becomes visible and a decor is created.
Mit dem erfindungsgemäßen Verfahren wird also das Druckbild nicht mit einem Druckverfahren erzeugt sondern mittels eines Lasers, wobei der Laser mittels des Laserstrahl einen Teil einer zuvor aufgebrachten Lackschicht entfernt. Mit diesem erfindungsgemäßen Verfahren werden ebenfalls die eingangs erwähnten Vorteile erzielt, d.h. die Umwelt wird weniger stark' belastet, da weniger Abfälle zu entsorgen sind, die Umrustzeit vom einen Druckbild auf ein anderes Druckbild wird drastisch reduziert und die Kosten für die Herstellung derartiger Verschlüsse wird vermindert.With the method according to the invention, the printed image is therefore not generated using a printing method, but rather by means of a laser, the laser using the laser beam to remove part of a previously applied lacquer layer. With this novel process, the aforementioned advantages are also achieved, that the environment is less stress', as less waste to dispose of the Umrustzeit from a print image to another image will be drastically reduced and the cost of production of such closures is reduced ,
Gemäß einer bevorzugten Weiterbildung des Verfahrens werden mehrere Lackschichten übereinander und/oder nebeneinander auf die Oberseite der Verschlusskappe aufgetragen. Durch dieses Verfahren können auf einfache und preiswerte Weise mehrfarbige Druckbilder erzeugt werden, ohne dass hierfür mehrere Klischees verwendet werden müssen.According to a preferred development of the method, a plurality of lacquer layers are applied one above the other and / or next to one another on the upper side of the closure cap. With this method, multicolored printed images can be produced in a simple and inexpensive manner, without having to use several clichés.
Eine Weiterbildung des erfindungsgemäßen Verfahrens sieht vor, dass mittels des Lasers die oberste Lackschicht bis zu einer darunterliegenden Lackschicht oder bis zum Kunststoff des Werkstücks abgetragen wird. Auf diese Weise können ebenfalls mehrfarbige Druckbilder erzeugt werden, indem der Laserstrahl mehr oder weniger weit in die mehreren Lackschichten eindringt und Teile einer oder mehrerer Lackschichten entfernt.A further development of the method according to the invention provides that the top lacquer layer is removed by means of the laser as far as an underlying lacquer layer or up to the plastic of the workpiece. In this way, multicolored printed images can also be generated by the laser beam penetrating more or less deeply into the multiple layers of paint and removing parts of one or more layers of paint.
Mit Vorzug wird das Abtragen der Lackschichten punktförmig oder linienförmig oder flächig durchgeführt. Auf diese Weise können je nach Anforderung hohe Abtragsraten erzielt werden oder es kann eine gezielte, präzise Abtragung durchgeführt werden .The removal of the lacquer layers is preferably carried out punctiform or linear or flat. In this way, high removal rates can be achieved, depending on requirements, or targeted, precise removal can be carried out.
Zusammenfassend kann festgestellt werden, dass die erfindungsgemäße Verschlusskappe und das erfindungsgemäße Herstellungsverfahren für die Verschlusskappe die Umwelt schont und dass die Umstellung auf ein neues Druckbild schnell und einfach erfolgen kann und dass mit dem Verfahren derartige erfindungsgemäße Kappen preiswerter hergestellt werden können. In summary, it can be stated that the closure cap according to the invention and the production method according to the invention for the closure cap protect the environment and that the changeover to a new printed image can be carried out quickly and easily and that the method according to the invention can be produced more cheaply.
