Description

Die Erfindung betrifft eine dosenförmige Verpackung für insbesondere rieselfähige Produkte mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a can-shaped packaging for, in particular, free-flowing products with the features of the preamble of claim 1.

Verpackungen der vorgenannten Art sind in einer Vielzahl von Ausführungsformen bekannt. Die Hülse besteht -je nach Verpackungsgut- entweder nur aus Karton oder aus einem mehrschichtigen Verbund mit einem hohen Anteil an Karton, ggf. einer inneren und/oder äußeren Kunststoffbeschichtung und bei besonderen Anforderungen aus einer Aluminiumfolie als Gas- und Feuchtigkeitssperrschicht. Solche Verpackungen sind an ihrer Deckelseite in der Regel durch eine angesiegelte Membran verschlossen und werden nach dem Abfüllen durch ihre offene Bodenseite an dieser durch einen Boden, z.B. aus Weißblech, Aluminium, Kunststoff, Karton oder Kartonverbund, verschlossen. Der Verbraucher reißt die Membran auf, um das Verpackungsgut entnehmen zu können. Um den Behälter nach dem Öffnen der Membran wieder verschließen zu können, gehört zu einer solchen Verpackung ein gesonderter Deckel, der in der Regel als Spritzgußteil aus Kunststoff hergestellt ist.Packaging of the aforementioned type is known in a variety of embodiments. Depending on the goods to be packaged, the sleeve either consists only of cardboard or of a multi-layer composite with a high proportion of cardboard, possibly an inner and / or outer plastic coating and, if special requirements arise, of an aluminum foil as a gas and moisture barrier layer. Such packagings are generally closed on their lid side by a sealed membrane and, after being filled through their open bottom side, are sealed on this by a bottom, for example made of tinplate, aluminum, plastic, cardboard or cardboard composite. The consumer tears open the membrane in order to be able to remove the packaged goods. In order to be able to close the container again after opening the membrane, such packaging includes a separate lid, which is usually an injection molded part is made of plastic.

Eine solche Verpackung ist nicht sortenrein, so daß ihre Entsorgung Schwierigkeiten bereitet. Es müssen insbesondere die Hülse, ggf. auch der Boden der Verpackung und insbesondere der Kunststoffdeckel gesondert entsorgt werden. Die Entsorgungskosten wiederum hängen von der Art des Verpackungsmaterials ab. So verursachen Karton- oder Kartonverbundmaterialien mit hohem Kartonanteil wesentlich geringere Entsorgungskosten als Kunststoffe.Such packaging is not sorted, so that it is difficult to dispose of it. In particular, the sleeve, possibly also the bottom of the packaging and in particular the plastic cover, must be disposed of separately. The disposal costs in turn depend on the type of packaging material. For example, cardboard or cardboard composite materials with a high proportion of cardboard cause significantly lower disposal costs than plastics.

Eine einfache und vor allem kostengünstigere Entsorgung ist bei einer bekannten Verpackung mit den Merkmalen des Oberbegriffs des Anspruchs 1 (CH-A-679 034) dadurch gegeben, daß der Deckel aus einem dessen Boden und Seitenwand umfassenden Tiefziehteil aus Karton oder Kartonverbund und einem gesondert hergestellten, mit dem Tiefziehteil verbundenen Ringteil besteht, das wiederum als napfförmiges tiefgezogenes Formteil gleichfalls aus Karton oder Kartonverbund mit einem Boden und einer Seitenwand hergestellt ist, dessen Boden zur Bildung eines Griffrandes teilweise ausgestanzt ist und das umgekehrt auf das andere Tiefziehteil aufgesetzt und mit dessen Seitenwand durch Kleben oder Heißsiegeln verbunden ist.A simple and, above all, less expensive disposal is provided in a known packaging with the features of the preamble of claim 1 (CH-A-679 034) in that the lid is made of a deep-drawn part made of cardboard or cardboard composite and the bottom and side wall of the part and a separately manufactured one , connected to the deep-drawn part ring part, which in turn is also made as a cup-shaped deep-drawn molded part from cardboard or cardboard composite with a bottom and a side wall, the bottom of which is partially punched out to form a grip edge and which, conversely, is placed on the other deep-drawn part and with its side wall Gluing or heat sealing is connected.

Bei dieser bekannten Verpackung besteht der gesamte zweiteilig hergestellte Deckel aus Karton oder einem Kartonverbund, so daß die gesamte Verpackung als sortenrein bezeichnet werden kann und sich folglich kostengünstig entsorgen läßt. Indes hat diese Verpackung einige gebrauchstechnische Nachteile. Das in die Hülse eingesetzte Tiefziehteil weist einen nach außen abgebogenen Randflansch auf, mit dem der Deckel auf der Stirnseite der Hülse abgestützt ist. Aufgrund der geringen Wandstärke des Randflansches und dessen 90°-Abbiegung sowie aufgrund des durch die geringe Wandstärke der Hülse vorgegebenen schmalen Übergriffs des Randflansches ist der Deckel von oben nicht belastbar bzw. drückt sich bei Druck von oben leicht in die Hülse hinein. Ferner liegt die Schnittkante am Randflansch frei, so daß Feuchtigkeit in den Karton des Deckels eintreten kann und dieser delaminiert oder aufquillt.In this known packaging, the entire two-part lid is made of cardboard or a cardboard composite, so that the entire packaging can be described as sorted and can therefore be disposed of inexpensively. However, this packaging has some technical disadvantages. The deep-drawn part inserted into the sleeve has an outwardly bent edge flange with which the cover is supported on the end face of the sleeve. Due to the thin wall of the Edge flange and its 90 ° bend as well as due to the narrow overlap of the edge flange given by the small wall thickness of the sleeve, the cover cannot be loaded from above or presses slightly into the sleeve when pressure is applied from above. Furthermore, the cut edge on the edge flange is exposed, so that moisture can enter the cardboard of the cover and this delaminates or swells.

Der Erfindung liegt die Aufgabe zugrunde, die gebrauchstechnischen Eigenschaften des Deckels an einer sortenreinen Verpackung aus Karton oder Kartonverbund zu verbessern.The invention has for its object to improve the technical properties of the lid on a pure packaging made of cardboard or cardboard composite.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das napfförmige Formteil an seiner im wesentlichen zylindrischen Wandung nach innen zur Doppellage umgeformt ist wobei es mit der doppellagigen Wandung die Seitenwand des anderen Tiefziehteils außenseitig übergreift, in diesem Bereich mit jener verbunden ist und auf der Stirnseite der Hülse aufliegt.This object is achieved in that the cup-shaped molded part on its substantially cylindrical wall is formed inwards to form a double layer, with the double-layer wall overlapping the side wall of the other deep-drawn part on the outside, connected in this area to that and on the end face of the sleeve lies on.

Durch die erfindungsgemäße Ausbildung ergibt sich ein Eindrückdeckel mit seinen bekannten Vorteilen. Die beiden umgekehrt ineinander eingreifenden Teile ergeben ein formstabiles Gebilde, das den beim Gebrauch auftretenden Kräften problemlos Stand hält. Ferner wird vermieden, daß an der Stirnseite der Wandung des das Ringteil bildenden Formteils eine Schnittkante freiliegt, die abgedeckt werden müßte, vielmehr ist bei dieser Ausführung die Stirnkante von dem Umbug der Wandung gebildet. Die Schnittkante selbst liegt an der Innenseite und kann ggf. von dem Boden des napffömigen Formteils abgedeckt sein.The design according to the invention results in a press-in cover with its known advantages. The two parts that interlock with each other result in a dimensionally stable structure that easily withstands the forces that occur during use. Furthermore, it is avoided that a cut edge that would have to be covered is exposed on the end face of the wall of the molded part forming the ring part, rather it is in this embodiment the front edge is formed by the fold of the wall. The cutting edge itself lies on the inside and can optionally be covered by the bottom of the cup-shaped molded part.

Ein Ausführungsbeispiel zeichnet sich dadurch aus, daß der Boden des Ringteils an dem Rand der den Griffrand bildenden Ausstanzung nach innen umgebogen ist. Diese Maßnahme dient insbesondere der Versteifung des Bodens im Bereich der Ausstanzung und es wird ferner die an dieser Stelle vorhandene Schnittkante nach innen verlagert.An embodiment is characterized in that the bottom of the ring part is bent inwards at the edge of the punched-out portion forming the grip edge. This measure serves in particular to stiffen the base in the area of the punched-out area and the cutting edge present at this point is also shifted inwards.

In einer weiteren Ausgestaltung kann vorgesehen sein, daß der Boden des Ringteils an dem Rand der den Griffrand bildenden Ausstanzung bis zur Doppellage nach innen umgebogen ist.In a further embodiment it can be provided that the bottom of the ring part at the edge of the punch-out forming the handle edge is bent inwards up to the double layer.

Bei dieser Ausgestaltung weist der am stärksten beanspruchte Griffrand durch die Doppellage eine hohe Steifigkeit auf, so daß selbst bei geringer Wandstärke des Ausgangsmaterials eine hinreichende Festigkeit gegeben ist.In this embodiment, the edge of the handle, which is subject to the greatest stress, has a high rigidity due to the double layer, so that there is sufficient strength even with a thin wall of the starting material.

Wie bei den dosenförmigen Verpackungen mit Kunststoffdeckel an sich bekannt ist, kann auch bei der erfindungsgemäß ausgebildeten Verpackung das Ringteil an seiner Peripherie am Übergang zwischen dem Boden und der Seitenwand eine nach innen eingezogene, umlaufende Stapelstufe aufweisen, die eine aufgesetzt gleichartige Verpackung im Bereich deren Bodens zentriert und fixiert.As is known per se in the case of can-shaped packaging with a plastic lid, the ring part at the periphery at the transition between the bottom and the side wall can also have an inwardly drawn, circumferential stacking step in the case of the packaging designed according to the invention, which has a similar type of packaging placed in the area of its bottom centered and fixed.

Nachstehend ist die Erfindung anhand eines in der Zeichnung wiedergegebenen Ausführungsbeispiels beschrieben, die einen abgebrochenen Längsschnitt einer dosenförmigen Verpackung im Bereich des Deckels zeigt.The invention is described below with reference to an embodiment shown in the drawing, which shows a broken longitudinal section of a can-shaped packaging in the region of the lid.

Die in der Zeichnung gezeigte Verpackung weist eine Hülse 1 auf, die kreiszylindrisch, oval oder in sonstiger Weise von der Kreisform abweichen kann. Sie besteht aus Karton oder einem mehrschichtigen Verbundmaterial auf der Grundlage von Karton. Beispielsweise kann die Hülse 1 innenseitig eine Kunststoffbeschichtung, ggf. auch eine Aluminiumsperrschicht und schließlich auch auf der Außenseite eine Kunststoffbeschichtung aufweisen. Die Verpackung weist ferner einen in der Zeichnung nicht wiedergegebenen Boden und einen Deckel 2 auf, der als Eindrückdeckel ausgebildet ist. Bei Verpackungen dieser Art ist darüber hinaus in der Regel ein Originalitätsverschluß in Form einer nicht gezeigten Verschlußmembran vorgesehen, welche die offene Stirnseite der Hülse 1 dicht verschließt und gleichfalls in die Hülse 1 hinein tiefgezogen ist.The packaging shown in the drawing has a sleeve 1 which can be circular-cylindrical, oval or in some other way deviate from the circular shape. It consists of cardboard or a multi-layer composite material based on cardboard. For example, the sleeve 1 can have a plastic coating on the inside, possibly also an aluminum barrier layer and finally also a plastic coating on the outside. The packaging also has a base (not shown in the drawing) and a cover 2, which is designed as a press-in cover. In packaging of this type, a tamper-evident closure is usually provided in the form of a closure membrane, not shown, which seals the open end face of the sleeve 1 and is also deep-drawn into the sleeve 1.

Bei dem gezeigten Ausführungsbeispiel besteht der Deckel 2 aus einem Tiefziehteil 3, das aus einer Karton oder Kartonverbund-Platine hergestellt ist, und einem Ringteil 6. Das Tiefziehteil 3 weist einen Boden 4 und eine im wesentlichen zylindrische Seitenwand 5 auf, wobei der Umriß des Tiefziehteils 3 im wesentlichen dem inneren Umriß der Hülse 1 entspricht, so daß es relativ satt in die Hülse eingreifen kann. Ferner weist der Boden 4 des Tiefziehteils 3 im mittleren Bereich eine Vertiefung 14 auf, die vornehmlich der Versteifung des scheibenförmigen Bodens 4 dient.In the embodiment shown, the lid 2 consists of a deep-drawn part 3, which is made of a cardboard or cardboard composite board, and a ring part 6. The deep-drawn part 3 has a bottom 4 and an essentially cylindrical side wall 5, the outline of the deep-drawn part 3 corresponds essentially to the inner contour of the sleeve 1, so that it can engage relatively well in the sleeve. Furthermore, the bottom 4 of the deep-drawn part 3 has a depression 14 in the central region, which serves primarily to stiffen the disk-shaped bottom 4.

Das Ringteil 6 besteht wie das Tiefziehteil 3 aus einem tiefgezogenen napfförmigen Formteil aus Karton oder Kartonverbund. Dieses napfförmige Formteil wird gebildet von dem Boden 15 und der Wandung 16, die nach innen zur Doppellage umgebogen ist, wobei die innere Lage 17 an der Außenseite der Seitenwand 5 des Tiefziehteils anliegt und dort mit diesem verbunden ist. Die offene Schnittkante 7 der Seitenwand 5 des Tiefziehteils 3 wird von dem das Ringteil 6 bildenden napfförmigen Formteil abgedeckt. Der Boden 15 des tiefgezogenen Ringteils 6 weist eine Ausstanzung 18 auf, durch die ein Griffrand 13 gebildet wird. Beim gezeigten Ausführungsbeispiel ist der Boden 15 im Bereich der Schnittkante 19 der Ausstanzung 18 nach innen umgebogen, so daß ein Versteifungsring entsteht und somit ein stabiler Griffrand 13 geschaffen wird.Like the deep-drawn part 3, the ring part 6 consists of a deep-drawn part Cup-shaped molded part made of cardboard or cardboard composite. This cup-shaped molded part is formed by the bottom 15 and the wall 16, which is bent inwards to form a double layer, the inner layer 17 resting against the outside of the side wall 5 of the deep-drawn part and being connected to it there. The open cutting edge 7 of the side wall 5 of the deep-drawn part 3 is covered by the cup-shaped molded part forming the ring part 6. The bottom 15 of the deep-drawn ring part 6 has a punched-out area 18 through which a grip edge 13 is formed. In the exemplary embodiment shown, the base 15 is bent inwards in the region of the cut edge 19 of the punched-out portion 18, so that a stiffening ring is created and thus a stable grip edge 13 is created.

Der Deckel 2 ist an seiner Peripherie zu einer Stapelstufe 20 nach innen gezogen, so daß eine gleichartige Verpackung mit der Hülse 1 aufgesetzt werden kann und an der Stapelstufe zentriert und fixiert wird.The lid 2 is pulled inwards at its periphery to form a stacking step 20, so that a similar packaging can be placed on the sleeve 1 and centered and fixed on the stacking step.
