Abstract
Die Erfindung betrifft einen Label (1) (Zettel, Etikett, Folienabschnitt) zum Einlegen und Hinterspritzen in der Spritzgießform einer Kunststoff-Spritzgussmaschine nach einem In-Mould-Labeling-Verfahren für einen rotationssymmetrische(n) Behälter (2) oder Verpackung mit außenseitig konvex ausgebauchter und/oder konkav eingebauchter Außenwand, wobei das Label (1) an mindestens einem seiner aneinander anstoßenden oder einander überlappenden oder miteinander einen Abstand bildenden Endränder (3) im Bereich der Ausbauchung (5) und/oder Einbauchung (8) der Außenwand (4) mindestens einen Schlitz (7) aufweist, der in dem jeweiligen Label-Endrand (3) mündet.The invention relates to a label (1) (label, label, film section) for insertion and injection molding in the injection mold of a plastic injection molding machine according to an in-mold labeling method for a rotationally symmetrical (n) container (2) or packaging convex on the outside bulged and / or concavely inserted outer wall, wherein the label (1) on at least one of its abutting or overlapping or a distance forming end edges (3) in the region of the bulge (5) and / or indentation (8) of the outer wall (4 ) has at least one slot (7), which opens in the respective label end edge (3).
Description
Die Erfindung betrifft ein Label insbesondere Zettel, Etikett oder Folienabschnitt zum Einlegen und Hinterspritzen in der Spritzgießform einer Kunststoff-Spritzgussmaschine nach einem In-Mould-Labeling-Verfahren für einen rotationssymmetrische(n) Behälter oder Verpackung mit außenseitig konvex ausgebauchter und/oder konkav eingebauchter Außenwand.The invention relates to a label, in particular slip, label or film section for insertion and injection molding in the injection mold of a plastic injection molding machine according to an in-mold labeling method for a rotationally symmetrical (n) container or packaging with outside convexly bulged and / or concave outer wall ,
Bei der Herstellung von rotationssymmetrischen, hohlen Behältern aus Kunststoff in einer Spritzgussmaschine im IML-Verfahren hat es sich gezeigt, dass im Bereich einer Ausbauchung und/oder Vertiefung/Einbauchung der Wandung des rotationssymmetrischen Behälters es zu Streckungen und Stauchungen des durch IML eingelegten Labels kommt, so dass das Label dort leicht Falten bildet. Ferner tritt im Bereich der aneinanderliegenden Endränder des Labels während des Einspritzens des Kunststoffs häufig Kunststoff aus und erstreckt sich über die Außenseite des Labels.In the production of rotationally symmetrical, hollow plastic containers in an injection molding machine in the IML process, it has been found that, in the region of a bulge and / or depression / indentation of the wall of the rotationally symmetrical container, stretching and compression of the label inserted by IML occur. so that the label easily folds there. Furthermore, in the region of the abutting end edges of the label, during the injection of the plastic, plastic often emerges and extends beyond the outside of the label.
Aufgabe der Erfindung ist es, ein im IML-Verfahren verwendetes Label so zu verbessern, dass im Bereich von Aus- und Einbauchungen des Behälters Falten und Risse im Label nicht entstehen und ein Austreten von Kunststoff während des Einspritzens verhindert wird.The object of the invention is to improve a label used in the IML process in such a way that folds and cracks in the label do not arise in the region of bulges and indentations of the container and leakage of plastic during injection is prevented.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Label an mindestens einem seiner aneinander anstoßenden oder einander überlappenden oder miteinander einen Abstand bildenden Endränder im Bereich der Ausbauchung und/oder Einbauchung der Außenwand mindestens einen Schlitz aufweist, der in dem jeweiligen Label-Endrand mündet.This object is achieved in that the label has at least one of its abutting or overlapping or each other at a distance forming end edges in the bulge and / or bulge of the outer wall at least one slot which opens into the respective label end edge.
Durch solche, in den Labelendrändern eingebrachte Schlitze im Bereich der konvexen und konkaven Behälterwandbereiche werden Falten und Risse des Labels sicher verhindert und zudem tritt Kunststoff nicht unkontrolliert nach außen aus über die Außenseite des Labels.By such, introduced into the label edges slots in the convex and concave container wall areas wrinkles and cracks of the label are reliably prevented and also occurs plastic is not uncontrolled outward on the outside of the label.
Vorzugsweise wird vorgeschlagen, dass das Label an seinen beiden Label-Endrändern jeweils mindestens einen Schlitz aufweist. Auch sollte der Schlitz mit dem Label-Endrand einen Winkel von 65 bis 115 Grad vorzugsweise von 90 Grad bilden.It is preferably proposed that the label has at least one slot at its two label end edges. Also, the slot with the label end edge should form an angle of 65 to 115 degrees, preferably 90 degrees.
Vorzugsweise wird vorgeschlagen, dass das Label (

Besonders vorteilhaft ist das Anordnen von Schlitzen im Label-Endrand bei der Herstellung von Kunststoffbechern insbesondere von Verpackungs- oder Getränkebechern im Spritzgussverfahren. Hierbei kann der Becher in seinem oberen Bereich eine Ausbauchung bilden, die nach unten in eine sich nach unten verjüngende Kegelstumpfform übergeht.Particularly advantageous is the arrangement of slots in the label end edge in the production of plastic cups in particular of packaging or beverage cups by injection molding. In this case, the cup can form a bulge in its upper region, which merges downward into a downwardly tapering truncated cone shape.
Das Label besteht aus Papier und/oder Kunststoff und verbindet sich beim Spritzgießen fest mit dem Becher über die der Kunststoffmasse zugewandten Seite.The label is made of paper and / or plastic and connects during injection molding firmly with the cup on the plastic mass side facing.
Vorzugsweise weist das im IML-Verfahren hergestellte Behältnis die Form eines Bechers auf mit einer rotationssymmetrischen Außenwand, die im oberen Bereich eine Ausbauchung bildet, an der sich darunter ein kegelstumpfförmiger Bereich stufenlos anschließt, dessen Durchmesser sich nach unten hin verringert.Preferably, the container produced in the IML method has the shape of a cup with a rotationally symmetrical outer wall, which forms a bulge in the upper region, at the below a truncated conical region connects steplessly, the diameter of which decreases towards the bottom.
