Description

Die Erfindung betrifft eine dosenförmige Verpackung mit einem Rumpf aus Papier- und/oder Kartonverbund mit einer wenigstens innenseitig vorgesehenen Kunststoffbeschichtung, einem an den Rumpf angesiegelten Boden und einem an der gegenüberliegenden Stirnseite angesiegelten Originalitätsverschluß, der für die Entnahme des Füllgutes geöffnet wird, wobei die Verpackung mittels eines Deckels aus Kunststoff wiederverschlossen werden kann, wie bekannt aus der DE-U-8 604 128.The invention relates to a can-shaped packaging with a body made of paper and / or cardboard composite with a plastic coating provided at least on the inside, a bottom sealed to the body and a tamper-evident closure sealed on the opposite end face, which is opened for the removal of the filling material, the packaging can be reclosed by means of a plastic cover, as is known from DE-U-8 604 128.

Verpackungen der vorgenannten Art, die auch als Kombi-Dosen bezeichnet werden, dienen in erster Linie zur Aufnahme fluider Füllgüter, wie Pulver für Instantgetränke, viskose bis pastöse Nahrungsmittel, wie Konfitüren oder dergleichen. Sie zeichnen sich gegenüber reinen Kunststoff- oder Metallverpackungen durch relativ geringe Materialkosten und weiterhin dadurch aus, daß die gebrauchte Verpackung umweltfreundlich aufgearbeitet werden kann. In der Regel sind diese Verpackungen kreiszylinderisch, oval oder abgerundet rechteckig ausgebildet. Sie weisen eine oder mehrere Lagen Papier, Pappe oder Karton auf und besitzen in der Regel eine diffusionsdichte Sperrschicht aus einer Metallfolie, Metallackierung oder einer Kunststoffbeschichtung. Um eine ausreichende Dichtheit zu erhalten, ist der Boden in der Regel im hot-melt-Verfahren am Rumpf angesiegelt. Deckelseitig ist in der Regel eine Verschlußmembran aus einer Metallfolie vorgesehen, die gleichfalls auf die Stirnseite des Rumpfs aufgesiegelt ist. Diese Verschlußmembran wiederum ist mit einer Aufreißlasche und gegebenenfalls einer Sollbruchlinie versehen, um sie leicht abtrennen zu können. Die Verschlußmembran bildet dabei nicht nur den dichten Abschluß der Verpackung, sondern bildet zugleich auch einen Originalitätsverschluß.Packaging of the aforementioned type, which are also referred to as combination cans, serve primarily to hold fluid filling goods, such as powders for instant beverages, viscous to pasty foods, such as jams or the like. Compared to pure plastic or metal packaging, they are characterized by relatively low material costs and also characterized in that the used packaging can be refurbished in an environmentally friendly manner. As a rule, these packages are circular cylindrical, oval or rounded rectangular. You assign one or several layers of paper, cardboard or cardboard and usually have a diffusion-tight barrier layer made of a metal foil, metal coating or a plastic coating. In order to maintain sufficient tightness, the floor is usually sealed to the fuselage using the hot-melt process. A cover membrane made of a metal foil is usually provided on the cover side and is likewise sealed onto the front side of the fuselage. This sealing membrane in turn is provided with a tear-open tab and, if necessary, a predetermined breaking line in order to be able to easily separate it. The sealing membrane not only forms the tight seal of the packaging, but also forms a tamper-evident seal.

Um das Füllgut nach dem Abtrennen der Verschlußmembran zu schützen, ist im allgemeinen ein gesonderter Kunststoffdeckel in Form eines Eintauch- oder Stülpdeckels vorgesehen, der als Spritzgußteil ausgebildet ist. Der Deckel dient gleichzeitig für Transport, Lagerung und Aufbewahrung im Haushalt als stabilisierendes Element, um den nicht ausreichend formsteifen Rumpf im Bereich der Verschlußmembran bzw. - nach deren Abtrennen - im Bereich der Öffnung in Form zu halten.In order to protect the contents after the closure membrane has been removed, a separate plastic cover in the form of an immersion or slip cover is generally provided, which is designed as an injection molded part. The lid also serves as a stabilizing element for transport, storage and storage in the household, in order to keep the not sufficiently rigid body in the area of the closure membrane or - after its separation - in the area of the opening.

Der Erfindung liegt die Aufgabe zugrunde, eine Verpackung des vorgenannten Aufbaus in konstruktiver Hinsicht zu vereinfachen und in kostenmäßiger Hinsicht günstiger sowie umweltfreundlicher zu gestalten.The invention has for its object to simplify the packaging of the aforementioned structure in terms of construction and to make it more economical and environmentally friendly in terms of cost.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Deckel aus einem Kunststoff-Ringteil, das mit dem Rumpf im wesentlichen umrißgleich und auf dessen Stirnseite aufgesiegelt ist, und einer in das Ringteil eingespritzten, den Rumpf stirnseitig überspannenden Scheibe aus Papier- und/oder Kartonverbund besteht, die entlang ihres Umfangs von einem schmalen Materialstreifen des Ringteils abgedeckt ist, der seinerseits über einen Teil des Umfangs abtrennbar ist.This object is achieved in that the lid consists of a plastic ring part, which is essentially the same outline as the fuselage and is sealed onto the end face thereof, and an injected disc into the ring part, spanning the fuselage on the end face, of paper and / or cardboard composite , which is covered along its circumference by a narrow strip of material of the ring part, which in turn is separable over part of the circumference.

Bei der erfindungsgemäß ausgebildeten Verpackung entfällt zunächst die bisher notwendige Verschlußmembran, indem der Deckel selbst auf den Rumpf aufgesiegelt ist und somit den für die notwendige Dichtheit sorgenden Verschluß bildet. Zugleich stellt der angesiegelte Deckel den Originalitätsverschluß dar. Im Gegensatz zur bekannten Ausführung besteht jedoch der Deckel nicht vollständig aus Kunststoff, sondern lediglich im Umfang des Ringteils, das auf den Rumpf aufgesiegelt ist. Dieses Ringteil verleiht dennoch der Verpackung eine ausreichende Formstabilität. Der überwiegende Teil des Deckels ist von einer den Querschnitt des Rumpfs überspannenden Scheibe aus Pappe, Karton oder einem Papier- oder Kartonverbund gebildet. Diese Scheibe braucht nur eine das Eindrücken verhindernde Formsteifigkeit zu besitzen. Sie wird anläßlich der Herstellung des Ringteils im Wege des Spritzgießens in die Kunststoffmasse eingespritzt, wobei sie oberseitig von einem Materialstreifen des Ringteils übergriffen ist, der entlang des Umfangs der Scheibe verläuft. Dieser Materialstreifen läßt sich zumindest über einen Teil des Umfangs von dem Ringteil abtrennen, so daß die Scheibe in diesem Bereich freigelegt wird und nach oben angehoben werden kann, um auf diese Weise das Füllgut entnehmen zu können. Durch erneutes Andrücken der Scheibe gegen das Ringteil kann der Behälter wieder verschlossen werden.In the case of the packaging designed according to the invention, the previously necessary closure membrane is dispensed with, in that the lid itself is sealed onto the fuselage and thus forms the closure which ensures the necessary tightness. At the same time, the sealed lid represents the tamper-evident closure. In contrast to the known design, however, the lid is not completely made of plastic, but only in the circumference of the ring part which is sealed onto the fuselage. This ring part nevertheless gives the packaging sufficient dimensional stability. The majority of the lid is formed by a cardboard, cardboard or paper or cardboard composite disc spanning the cross section of the fuselage. This disc only needs to have a stiffness that prevents indentation. It is injected into the plastic mass during the manufacture of the ring part by means of injection molding, wherein it is overlapped on the top by a material strip of the ring part which runs along the circumference of the disk. This strip of material can be separated from the ring part at least over part of the circumference, so that the disc is exposed in this area and can be lifted upwards in order to be able to remove the filling material in this way. The container can be closed again by pressing the disc against the ring part.

Bei der erfindungsgemäß ausgebildeten Verpackung entfällt nicht nur die Verschlußmembran, sondern es wird beim Deckel auch Kunststoffmasse eingespart und diese Masse durch ein leichteres und umweltfreundlicher zu verarbeitendes Material ersetzt. Insgesamt wird damit eine Verpackung erhalten, die sich vom Materialaufwand und von der Fertigungstechnik her kostengünstiger herstellen läßt und die weitestgehend aus einem umweltfreundlich aufzuarbeitenden Material besteht. Hinzu kommt, daß die Deckelfläche besser und einfacher bedruckt werden kann, als dies bei einem reinen Kunststoffdeckel der Fall ist.In the case of the packaging designed according to the invention, not only is the sealing membrane omitted, but plastic mass is also saved in the lid and this mass is replaced by a lighter and more environmentally friendly material. Overall, a package is obtained which can be manufactured more cost-effectively in terms of material expenditure and manufacturing technology and which largely consists of an environmentally friendly material. In addition, the lid surface prints better and easier can be, as is the case with a pure plastic cover.

Es sind zwar in der Verpackungstechnik bereits Behälterdeckel vorgeschlagen worden, die aus einem Kunststoff-Pappeverbund bestehen, jedoch handelt es sich hierbei um einfache Stülp- oder Eintauchdeckel, die weder die Aufgabe eines Dichtheits- und Originalitätsverschlusses erfüllen, noch eine integrierte Öffnungsmechanik besitzen.Although container lids have already been proposed in packaging technology, which consist of a plastic / cardboard composite, these are simple slip or immersion lids, which neither fulfill the function of a tightness and tamper-evident closure, nor do they have an integrated opening mechanism.

Eine bevorzugte Ausführungsform zeichnet sich dadurch aus, daß die Scheibe eine vorgefertigte Biegelinie aufweist, die etwa mit der Verbindungslinie der Endpunkte des abtrennbaren Teils des Materialstreifens zusammenfällt.A preferred embodiment is characterized in that the disc has a prefabricated bending line which coincides approximately with the connecting line of the end points of the separable part of the material strip.

Auf diese Weise kann die Scheibe nach dem Abtrennen des Materialstreifens problemlos angehoben bzw. aufgeklappt werden, um das Füllgut entnehmen zu können. Ebenso läßt sich der aufklappbare Teil der Scheibe leicht wieder in die Schließlage bringen. Die Biegelinie kann dabei so ausgebildet und angebracht sein, daß sie auf das klappbare Teil der Scheibe eine Rückstellkraft ausübt, die sie in die Schließlage drängt. Stattdessen oder zusätzlich ist es auch möglich, an dem Ringteil in dem Bereich des abgetrennten Materialstreifens kleine Vorsprünge oder dergleichen stehenzulassen, um den aufklappbaren Teil der Scheibe in der Schließlage einrasten zu können.In this way, after the strip of material has been cut off, the pane can be lifted or opened without problems in order to be able to remove the filling material. Likewise, the hinged part of the pane can be easily brought back into the closed position. The bending line can be designed and attached so that it exerts a restoring force on the foldable part of the pane, which forces it into the closed position. Instead of or in addition, it is also possible to allow small projections or the like to stand on the ring part in the region of the severed material strip in order to be able to latch the hinged part of the pane in the closed position.

Zweckmäßigerweise ist der teilweise abtrennbare Materialstreifen mit einer Aufreißlasche versehen, die sein Abtrennen erleichtert, wobei diese Aufreißlasche vorteilhafterweise an dem Ringteil in einer zur Scheibe parallelen Lage angespritzt und nach oben abbiegbar ist, um im Neuzustand eine annähernd ebene Deckenfläche zu erhalten.The partially detachable material strip is expediently provided with a tear-off tab which facilitates its detachment, this tear-open tab advantageously being injection-molded onto the ring part in a position parallel to the disc and being bendable upward in order to obtain an approximately flat ceiling surface when new.

Es ist weiterhin von Vorteil, wenn die Scheibe an der der Biegelinie gegenüberliegenden Seite mit einer Zuglasche versehen ist, so daß auch der zum Öffnen vorgesehene Teil der Scheibe problemlos aufgeklappt werden kann.It is also advantageous if the pane is provided with a pull tab on the side opposite the bending line, so that the part of the pane intended for opening can also be opened without problems.

In weiterhin bevorzugter Ausgestaltung ist vorgesehen, daß der teilweise abtrennbare Materialstreifen zugleich einen nach oben ragenden Stapelrand für den Boden einer gleichartigen Verpackung bildet.In a further preferred embodiment it is provided that the partially detachable material strip also forms an upwardly projecting stacking edge for the bottom of a similar packaging.

Der teilweise abtrennbare Materialstreifen bildet also im Originalzustand der Verpackung einen Stapelrand für Transport, Aufbewahrung und Präsentation der Verpackung. Gelangt die Verpackung an den Endverbraucher, wird der Stapelrand nicht mehr benötigt, so daß er teilweise abgetrennt werden kann, um die Verpackung zu öffnen und das Füllgut entnehmen zu können.In the original condition of the packaging, the partially detachable material strip forms a stacking edge for transport, storage and presentation of the packaging. If the packaging reaches the end user, the edge of the stack is no longer required, so that it can be partially separated in order to open the packaging and to be able to remove the contents.

Gemäß einem weiteren vorteilhaften Ausführungsbeispiel ist vorgesehen, daß das Ringteil zwei konzentrische, den Rumpf stirnseitig sowie außen- und innenseitig eng übergreifende Ansätze aufweist.According to a further advantageous embodiment, it is provided that the ring part has two concentric approaches that closely overlap the fuselage on the front side and on the outside and inside.

Auf diese Weise ist nicht nur eine einwandfreie dichte Versiegelung des Ringteils mit dem Rumpf möglich, sondern das Ringteil kann auch seine stabilisierende Funktion gegenüber dem Rumpf einwandfrei erfüllen.In this way, not only is it possible to properly seal the ring part to the fuselage, the ring part can also perform its stabilizing function with respect to the fuselage.

Die Scheibe kann wenigstens eine diffusionsdichte, z.B. metallische, Sperrschicht aufweisen. Diese kann gegenüber der bisher notwenigen Verschlußmembran wesentlich dünner ausgebildet sein. Während herkömmliche Verschlußmembrane eine Wandstärke von 50 µm besitzen, reicht für die Scheibe eine 9 µm Kaschierung aus. Dadurch und durch die Einsparung eines großen Teils an Kunststoffmasse läßt sich hinsichtlich des Verschlußes eine Gewichtsersparnis im Bereich von 1/3 erzielen.The pane can have at least one diffusion-tight, for example metallic, barrier layer. This can be made much thinner than the previously necessary sealing membrane. While conventional sealing membranes have a wall thickness of 50 µm, a 9 µm lamination is sufficient for the pane. As a result of this and by saving a large amount of plastic mass, a weight saving in the range of 1/3 can be achieved with regard to the closure.

Nachstehend ist die Erfindung anhand eines in der Zeichnung wiedergegebenen Ausführungsbeispiels beschrieben. In der Zeichnung zeigen:

The invention is described below using an exemplary embodiment shown in the drawing. The drawing shows:
Figure 1
a cross section in the upper region of the packaging in the original condition;
Figure 2
a section similar to Figure 1 in the open state and
Figure 3
a plan view of the package of Figure 1.

Von der in der Zeichnung wiedergegebenen dosenförmigen Verpackung ist lediglich der Rumpf 1 und der oberseitige Verschluß 2 wiedergegeben, nicht jedoch der bodenseitige Abschluß. Der Rumpf 1 besteht aus einem Papier- oder Pappeverbund 3, der innenseitig eine metallische Sperrschicht 4 und eine Kunststoffkaschierung 5 sowie außenseitig eine Papierkaschierung 6 zum Bedrucken aufweist. Der Rumpf 1 ist an seiner dem Boden gegenüberliegenden Stirnseite durch einen Verschluß 2 in Form eines Deckels verschlossen.Of the can-shaped packaging shown in the drawing, only the fuselage 1 and the top closure 2 are shown, but not the bottom end. The fuselage 1 consists of a paper or cardboard composite 3 which has a metallic barrier layer 4 on the inside and a plastic lamination 5 and a paper lamination 6 on the outside for printing. The fuselage 1 is closed on its end face opposite the floor by a closure 2 in the form of a cover.

Der Deckel 2 besteht aus einem Ringteil 7 aus Kunststoff, das mit zwei nach unten ragenden konzentrischen Ansätzen 8, 9 den Rumpf 1 stirnseitig und außen- sowie innenseitig eng übergreift. Das Ringteil 7 ist an dem Rumpf 1 angesiegelt, beispielsweise unter Heranziehung der innenseitigen Kunststoffbeschichtung 5.The cover 2 consists of a ring part 7 made of plastic, which tightly engages over the fuselage 1 on the front and outside and inside with two concentric projections 8, 9 projecting downwards. The ring part 7 is sealed to the fuselage 1, for example by using the plastic coating 5 on the inside.

Der Deckel 2 weist ferner eine den Querschnitt des Rumpfs 1 überspannende Scheibe 10 aus Pappe oder Pappeverbund auf, die entlang ihres Umfangs 11 in das Ringteil 7 eingespritzt ist. Beim gezeigten Ausführungsbeispiel weist das Ringteil 7 zu diesem Zweck einen nach oben ragenden Materialstreifen 12 auf, der zugleich einen Stapelrand bildet. Dieser Materialstreifen 12 übergreift die Scheibe 10 entlang ihres gesamten Umfangs. Dabei wird zwischen dem Materialstreifen 12 und dem die Stirnseite des Rumpfs 1 übergreifenden Bereich 13 eine als Sollbruchlinie 14 wirkende Materialschwächung vorgesehen. Diese Sollbruchlinie 14 verläuft, wie aus Figur 3 ersichtlich, entlang dreier Seiten der in diesem Fall rechteckförmigen Verpackung. Der Materialstreifen 12 weist ferner, wie Figur 3 zeigt, Trenn- bzw. Schnittstellen 15 auf. An dem Materialstreifen 12 ist eine Aufreißlasche 16 angespritzt, die im Originalzustand, wie aus Figur 3 ersichtlich, auf der Scheibe 10 aufliegt und, wie Figur 1 zeigt, nach oben abgebogen werden kann. Mittels der Aufreißflasche läßt sich der Materialstreifen 12 entlang der Sollbruchlinien 14 zwischen den Trennstellen 15 vom Ringteil abtrennen, so daß nur der in Figur 2 und 3 rechts erkennbare Teil des Materialstreifens stehen bleibt.The cover 2 also has a cardboard or cardboard composite disc 10 spanning the cross section of the fuselage 1, which is injected into the ring part 7 along its circumference 11. In the exemplary embodiment shown, the ring part 7 has an upwardly projecting material strip 12 for this purpose, which at the same time forms a stacking edge. This material strip 12 overlaps the disk 10 along its entire scope. In this case, a material weakening acting as a predetermined breaking line 14 is provided between the material strip 12 and the area 13 that overlaps the end face of the fuselage 1. This predetermined breaking line 14 runs, as can be seen from FIG. 3, along three sides of the packaging, which in this case is rectangular. The material strip 12 also has, as FIG. 3 shows, separation or interfaces 15. A tear-open tab 16 is molded onto the material strip 12, which in the original state, as can be seen in FIG. 3, rests on the pane 10 and, as shown in FIG. 1, can be bent upwards. By means of the tear-open bottle, the material strip 12 can be separated from the ring part along the predetermined breaking lines 14 between the separation points 15, so that only the part of the material strip which can be seen on the right in FIGS. 2 and 3 remains.

Die Scheibe 10 ist etwa entlang der Verbindungslinie der Trenn- bzw. Schnittstellen 15 mit einer eingeformten Biegelinie 17 versehen. Weiterhin weist die Scheibe an der der Biegelinie 17 gegenüberliegenden Seite eine Zuglasche 18 auf, die in das Ringteil eingespritzt ist und im Originalzustand flach auf der Scheibe aufliegt. Nach Abtrennen des Materialstreifens 12 kann die Zuglasche 18 ergriffen und die Scheibe diesseits der Biegelinie 17 angehoben werden. Die Scheibe 10 bildet also mit ihrem Abschnitt 19 eine Art Klappdeckel.The disk 10 is provided with a molded-in bending line 17 approximately along the connecting line of the separation or interfaces 15. Furthermore, the disc has a pull tab 18 on the side opposite the bending line 17, which is injected into the ring part and lies flat on the disc in the original state. After the strip of material 12 has been cut off, the pull tab 18 can be gripped and the pane can be raised on this side of the bending line 17. The disc 10 thus forms with its section 19 a kind of hinged lid.
