Description

Technisches GebietTechnical area

Die Erfindung betrifft ein teilweise geprägtes Deckelelement, welches auf den Rand eines Lebensmittelbehälters aufgesiegelt ist, sowie ein Verfahren zum Öffnen eines Lebensmittelbehälters, versehen mit einem auf den Rand des Lebensmittelbehälters aufgesiegelten Deckelelement.The invention relates to a partially embossed cover element, which on the edge of a food container is sealed, and a method for opening a food container, provided with a sealed on the edge of the food container Cover element.

Stand der TechnikState of the art

Üblicherweise werden Lebensmittelbehälter für Joghurts, aber auch für Trinkjoghurts, Softdrinks und Molkegetränke mittels Foliendeckeln verschlossen, welche beispielsweise aus Aluminium bestehen. Diese weisen meistens an ihrer Oberseite eine Druckschicht und eine Überlackschicht auf. Zur besseren Entstapelung an den Verpackungsmaschinen ist es ferner vorgesehen, die Oberfläche der Foliendeckel zumindestens teilweise zu prägen. Solche Deckelelemente sind aus dem Dokument FR 2731986 A bekannt. Die Unterseite der Foliendeckel weist eine Heißsiegelschicht auf, durch welche eine luftdichte Verbindung mit dem Rand des Lebensmittelbehälters erzeugt wird. Dennoch muß der Verbraucher zum Öffnen des Lebensmittelbehälters den Foliendeckel leicht vom Behälter schälen können. Wird der Foliendeckel jedoch bei besonders fließfähigen Verpackungsgütem, wie beispielsweise Trinkjoghurts, gänzlich vom Behälter geschält, so kann das Trinkjoghurt leicht ausgeschüttet werden.Usually food containers for yogurts, but also for drinking yoghurts, Soft drinks and whey drinks closed with foil lids, which consist for example of aluminum. These usually show theirs Top of a print layer and a topcoat on. For better Entstapelung on the packaging machines, it is also provided, the surface to at least partially emboss the foil lid. Such cover elements are known from document FR 2731986 A. The underside of the foil lid has a heat-sealing layer, through which an air-tight Connection with the edge of the food container is generated. Yet the consumer must open the food container, the Foliendeckel easy to peel from the container. However, the folio lid is included highly flowable packaging, such as drinking yoghurts, Peeled completely from the container, the drinking yoghurt can be easily spilled become.

Gemäß der DE-A1-195 23 754 wird daher ein Foliendeckel bestehend aus zumindestens zwei Folienschichten, welche mittels Kleber untereinander verbunden, sind vorgeschlagen. Während des Öffnens wird über eine Soll-Reiß-Linie in der dem Lebensmittel zugewandten Folienschicht eine Ausgießöffnung gebildet. Über diese Ausgießöffnung entnimmt der Verbraucher direkt das Lebensmittel, beispielsweise ein Trinkjoghurt. According to DE-A1-195 23 754, therefore, a Foliendeckel consisting of at least two film layers, which by means of adhesive with each other connected, are proposed. While opening it will have a nominal tear line in the film layer facing the food a pouring opening educated. About this pouring the consumer takes directly from the Food, such as a drinking yoghurt.

Dabei kann er jedoch mit Kleberspuren, welche am verbleibenden Foliendeckel vorliegen, in Hautkontakt kommen. Es ist daher relativ schwierig, mittels dieses vorbekannten Foliendeckels die üblichen lebensmittelrechtlichen Erfordernisse zu erfüllen. Ferner ist der vorbekannte Foliendeckel nur mit relativ hohem verfahrenstechnischen Aufwand herzustellen, da die Folienschichten untereinander verklebt werden müssen und zusätzlich die Soll-Reiß-Linie paßgenau in der dem Lebensmittel zugewandten Folienschicht angebracht werden muß.He can, however, with adhesive traces, which on the remaining Foliendeckel present, come into skin contact. It is therefore relatively difficult by means of this previously known Foliendeckels the usual food law requirements to fulfill. Furthermore, the previously known Foliendeckel only with relatively high procedural effort to produce, since the film layers must be glued together and also the target tear line fitted in registration in the food-facing film layer must become.

Aufgabe der vorliegenden Erfindung ist es daher, die aus dem Stande der Technik vorbekannten Nachteile zu vermeiden.Object of the present invention is therefore, from the prior Technology to avoid known disadvantages.

Darstellung der ErfindungPresentation of the invention

Erfindungsgemäß wird daher ein Deckelelement der eingangs genannten Art vorgeschlagen, welches dadurch gekennzeichnet ist, daß der glatte Bereich über eine Schwächungslinie vom geprägten Bereich des Deckelelementes getrennt ist, daß der glatte Bereich ebenso wie der geprägte Bereich über eine Siegelnaht dicht mit dem Behälter rand verbunden ist, jedoch eine, gegenüber dem geprägten Bereich reduzierte Siegelnahtfestigkeit aufweist und dadurch einen, den Öffnungsvorgang er leichternden Aufreißbereich darstellt. Vorteilhafterweise ist die Siegelnaht festigkeit im glatten Bereich des Deckelelementes gegenüber jener im geprägten Bereich um mindestens 3 N, gemessen am 15 mm Teststreifen, reduziert. Zur Erleichterung des Öffnungsvorganges kann die Schwächungslinie vorteil-hafterweise zumindestens teilweise perforiert sein. Zur weiteren Erleichterung des Öffnungsvorganges ist vorteilhafterweise im glatten Bereich des Deckelelementes eine Aufreißhilfe, vorzugsweise eine Lasche vorgesehen.The invention therefore provides a cover element of the type mentioned proposed, which is characterized in that the smooth area over a line of weakness separated from the embossed region of the cover element is that the smooth area as well as the embossed area via a sealed seam is tightly connected to the edge of the container, but one, opposite the embossed area has reduced seal seam strength and thereby the opening process he represents facilitating tear area. Advantageously, the sealed seam strength in the smooth area of the Cover element with respect to that in the embossed area by at least 3 N, measured on the 15 mm test strip, reduced. To facilitate the Opening process may advantageously the weakening line be at least partially perforated. To further facilitate the Opening operation is advantageously in the smooth area of the Cover element a tear-open, preferably provided a tab.

Das Deckelelement besteht vorzugsweise aus einer Aluminiumfolie mit einer Zugfestigkeit von 50 - 200 N/mm2.The cover element preferably consists of an aluminum foil with a tensile strength of 50-200 N / mm 2 .

Die Erfindung betrifft ferner ein Verfahren zum Öffnen eines Behälters für Lebensmittel, versehen mit einem auf den Rand des Lebensmittelbehälters aufgesiegelten Deckelelement, wobei der Behälter derart geöffnet wird,

  • daß die Klebekraft der Heißsiegelbeschichtung im glatten Bereich durch Anwendung der Anreißkraft (F), vorzugsweise an der Grifflasche, überwunden wird,
  • daß der glatte Bereich vom Behälterflansch geschält wird und
  • daß dieser derart eingeleitete Öffnungsmechanismus so lange fortgesetzt wird, bis zumindestens der glatte Bereich des Deckelelementes an der Schwächungslinie vom geprägten Bereich abgetrennt und dadurch die Entnahme des Lebensmittels über eine Ausgießöffnung ermöglicht wird.
The invention further relates to a method for opening a container for food, provided with a sealed onto the edge of the food container lid member, wherein the container is opened so,
  • that the adhesive force of the heat seal coating in the smooth area is overcome by applying the scribing force (F), preferably on the grip tab,
  • that the smooth area is peeled from the tank flange and
  • in that this opening mechanism introduced in this way is continued until at least the smooth area of the cover element at the line of weakness is separated from the embossed area, thereby enabling the removal of the food via a pouring opening.

Die Entnahme des Lebensmittels, vorzugsweise des Trinkjoghurts, wird in vorteilhafter Weise besonders dadurch erleichtert, daß eine Ausgießvorrichtung, vorzugsweise eine schnabelförmige, am Lebensmittelbehälter vorgesehen ist.The removal of the food, preferably the drinking yoghurt, is in advantageously particularly facilitated by a pouring device, preferably a beak-shaped, is provided on the food container.

Kurze Beschreibung der Zeichnungen und ein Weg zur Ausführung der ErfindungBrief description of the drawings and a way to carry out the invention

Die Erfindung wird nunmehr anhand der Figuren 1-4 sowie anhand eines Ausführungsbeispieles näher erläutert.

  • Figur 1 zeigt die Deckelelement-Oberseite (1a) des Deckelelementes (1), welches den geprägten Bereich (2) und den ungeprägten, sohin glatten Bereich (3) aufweist. Im glatten Bereich (3) ist eine Öffnungshilfe in Form einer Lasche (5) vorgesehen. Die Siegelnähte an der Unterseite des Deckelelementes sind mit (6) bzw. (6') angedeutet.
  • Figur 2 zeigt die Deckelelement-Unterseite (1b) des Deckelelementes (1), wobei im geprägten Bereich (2) der Heißsiegellackauftrag mit (7) bezeichnet wird, während im glatten Bereich (3) der Heißsiegellackauftrag mit (7') bezeichnet wird. Ferner sind die Siegelnähte (6) im geprägten Bereich (2) sowie (6') im glatten Bereich (3) wiedergegeben.
  • Figur 3 zeigt einen Lebensmittelbehälter (8) für beispielsweise ein Trinkjoghurt (11). Dieser weist den Behälterflansch (10) bzw. eine Ausgießvorrichtung (9) auf. Ferner ist in Figur 3 anhand von Pfeilen die Einwirkung der Anreißkraft (F), welche vom Verbraucher an der Lasche (5) ausgeübt wird, wiedergegeben. Dabei wird die Lasche (5) aufgrund dieser Anreißkraft (F) von der Siegelnaht (6') abgeschält, sodaß die Lasche (5) in ihrer strichlierten Form teilweise vom Behälterflansch (10) abgeschält wird.
  • Figur 4 zeigt den Behälter gemäß Figur 3, wobei durch die vorgenannte Anreißkraft (F) der glatte Bereich (3) bereits gänzlich vom geprägten Bereich (2), insbesondere über die Schwächungslinie (4) abgetrennt wurde. Dadurch entsteht eine fiir die Entnahme des Lebensmittels (11) vorgesehene Ausgießöffhung (12).
    • The invention will now be explained in more detail with reference to FIGS 1-4 and reference to an exemplary embodiment.
  • FIG. 1 shows the lid element upper side (1a) of the lid element (1), which has the embossed area (2) and the unembossed, thus smooth area (3). In the smooth area (3) an opening aid in the form of a tab (5) is provided. The sealing seams on the underside of the cover element are indicated by (6) or (6 ').
  • Figure 2 shows the lid member bottom (1b) of the lid member (1), wherein in the embossed area (2) of the heat seal coating order (7) is referred to, while in the smooth area (3) of the heat seal coating order (7 ') is called. Furthermore, the sealing seams (6) are reproduced in the embossed region (2) and (6 ') in the smooth region (3).
  • FIG. 3 shows a food container (8) for, for example, a drinking yoghurt (11). This has the container flange (10) and a pouring device (9). Furthermore, in FIG. 3, the action of the scribing force (F), which is exerted by the load on the tab (5), is reproduced by means of arrows. In this case, the tab (5) due to this scribing force (F) peeled off from the sealing seam (6 '), so that the tab (5) is partially peeled off in its dashed form from the container flange (10).
  • FIG. 4 shows the container according to FIG. 3, wherein the smooth area (3) has already been completely separated from the embossed area (2), in particular via the weakening line (4), by the aforementioned marking force (F). This results in a pouring opening (12) provided for the removal of the food (11).

    • Das Deckelelement, wie es in den Figuren 1 und 2 dargestellt ist, wird beispielsweise aus einer Aluminiumfolie mit einer Zugfestigkeit von 50 bis 200 N/mm2 hergestellt. Ferner ist es auch möglich, das Deckelelement aus Kunststoff, wie Polypropylen oder Polyethylentercphthalat oder aus Verbunden, bestehend aus Aluminium, Papier oder Kunststoff, herzustellen.The lid member as shown in Figs. 1 and 2 is made of, for example, an aluminum foil having a tensile strength of 50 to 200 N / mm 2 . Furthermore, it is also possible to produce the cover element made of plastic, such as polypropylene or polyethylene terephthalate, or of composites consisting of aluminum, paper or plastic.

    Die teilweise Prägung des Deckelelementes erfolgt, wie in der WO 99/29508 A der Anmelderin offenbart, mit einem über Sensoren gezielt gesteuerten Prägevorgang. Dafür werden über Druckmarken (nicht dargestellt) die geprägten und ungeprägten Bereiche an der Deckelelement-Oberfläche markiert. Durch den gezielt gesteuerten Prägevorgang werden nunmehr der geprägte Bereich (2), der glatte Bereich (3) sowie gleichzeitig die Schwächungslinie (4) erzeugt. Femer ist es möglich, die Schwächungslinie (4) als sogenannte Soll-Reiß-Linie auszubilden, wobei zusätzlich eine Perforierung vorgesehen wird. Anschließend werden die Deckelelemente - wie an sich bekannt - in die Form der Deckelelemente gemäß Figuren 1 und 2 gestanzt, wobei gleichzeitig die Grifflasche (5) ausgebildet wird.The partial embossing of the cover element takes place, as in WO 99/29508 A discloses the applicant, with a targeted via sensors controlled embossing process. For this are printed marks (not shown) the embossed and unembossed areas on the lid element surface marked. Due to the targeted controlled embossing process are now the embossed area (2), the smooth area (3) and at the same time the Weakening line (4) generated. Furthermore, it is possible to weaken the line of weakness (4) form as a so-called target-tear line, with an additional perforation is provided. Subsequently, the cover elements - as per se known - punched in the shape of the cover elements according to Figures 1 and 2, at the same time the grip tab (5) is formed.

    Aufgrund der teilweisen Prägung in der Deckelelement-Oberfläche weist die Heißsiegellackschicht (7') eine gegenüber der Heißsiegellackschicht (7) um zumindestens 3 N reduzierte Siegelnahtfestigkeit auf. Diese Siegelnahtfestigkeit wird anhand von 15 mm dicken Teststreifen einerseits an der geprägten Oberfläche (2) und andererseits an der glatten Oberfläche (3) gemessen. Durch die reduzierte Siegelnahtfestigkeit im glatten Bereich (3), in welchem ebenso die Aufreißhilfe in Form der Lasche (5) vorliegt, ergibt sich eine verbraucherfreundliche Reduzierung der Anreißkraft (F), mit welcher der Öffnungsmechanismus des Lebensmittelbehälters (8) eingeleitet wird. Due to the partial embossing in the lid element surface, the Heat sealing lacquer layer (7 ') one opposite the heat sealing lacquer layer (7) at least 3 N reduced seal strength. This seal seam strength is based on 15 mm thick test strips on the one hand on the embossed Surface (2) and on the other hand measured on the smooth surface (3). By the reduced seal strength in the smooth area (3), in which also the Aufreißhilfe in the form of the tab (5) is present, there is a Consumer friendly reduction of the scribing force (F), with which the Opening mechanism of the food container (8) is initiated.

    Der Lebensmittelbehälter (8) kann, wie an sich bekannt, aus tiefziehfähigen Kunststoffmaterialien bestehen und weist den Behälterflansch (10) und, in besonders vorteilhafter Weise, die Ausgießvorrichtung (9) auf.The food container (8), as known per se, from thermoformable Plastic materials consist and has the container flange (10) and, in Particularly advantageous manner, the pouring device (9).

    Diese kann schon während der Herstellung des Lebensmittelsbehälters in Form eines Schnabels ausgebildet werden.This can already during the production of the food container in the form a beak are formed.

    Durch die im glatten Bereich verminderte Anreißkraft (F) kann der Verbraucher in einfacher Weise die Aufreißhilfe im glatten Bereich, nämlich die Lasche (5), von der Siegelnaht (6') abziehen. Der anschließende Öffnungsvorgang erfolgt bis zur Schwächungslinie (4), welche den geprägten Bereich (2) vom glatten Bereich (3) trennt. An der Schwächungslinie (4) wird, wie in Figur 4 dargestellt, der glatte Bereich (3) vom geprägten Bereich (2) des Deckelelementes abgetrennt, sodaß die Ausgießöffnung (12) gebildet wird. Durch diese kann der Verbraucher in hygienisch unbedenklicher Weise das Lebensmittel, beispielsweise das Trinkjoghurt, entnehmen.By in the smooth area diminished Anreißkraft (F), the consumer in a simple way the Aufreißhilfe in the smooth area, namely the tab (5), remove from the sealing seam (6 '). The subsequent opening process takes place to the weakening line (4), which the embossed area (2) from the smooth Area (3) separates. At the weakening line (4), as shown in FIG. 4, the smooth area (3) of the embossed area (2) of the cover element separated, so that the pouring opening (12) is formed. Through this, the Consumers in a hygienic way the food, For example, the drinking yoghurt, remove.

    Gewerbliche AnwendbarkeitIndustrial Applicability

    Durch das Deckelelement, welches in einfacher Weise hergestellt werden kann, ist es einerseits gewährleistet, daß das Lebensmittel, beispielsweise das Trinkjoghurt, luftdicht verschlossen ist, und daß andererseits dieses durch die gebildete Ausgießöffnung (12) in hygienisch unbedenklicher Weise entnommen werden kann.By the cover element, which in a simple manner can be produced, it ensures, on the one hand, that the food, for example, the drinking yoghurt is hermetically sealed, and that on the other hand this through the formed pouring opening (12) in hygienic safe Way can be taken.
