Definitions
- the invention relates to a can-shaped packaging for in particular free-flowing products, consisting of a bottom-closed sleeve made of cardboard or a multi-layer composite made of cardboard and / or plastic and / or metal and a cup-shaped lid which can be inserted into the sleeve and has a bottom, an essentially cylindrical, the inside of the sleeve adjacent side wall and an upper ring part which has on the outside a step lying on the end face of the sleeve and an inwardly retracted grip edge.
- Packaging of the aforementioned type is known in a variety of embodiments.
- 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 packaging is usually on the lid side by a sealed membrane and are closed after filling through their open bottom side 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.
- a separate lid which is usually made of plastic as an injection molded part.
- Such packaging is not sorted, so that it is difficult to dispose of it.
- 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.
- the invention has for its object to provide a packaging of the structure mentioned above so that a simple and, above all, less expensive disposal is possible.
- the lid consists of a deep-drawn part made of cardboard or cardboard composite comprising its bottom and side wall and a separately produced ring part connected to the deep-drawn part.
- the larger part of the lid — in terms of volume and weight — consists of a cardboard or cardboard composite, which causes comparatively low disposal costs, while the ring part has a comparatively small volume and weight. If necessary, this ring part can also be easily separated from the deep-drawn part and disposed of separately.
- the two-part design makes it possible to shape the part of the cover consisting of the bottom and side wall by deep drawing.
- the ring part can be made of plastic and can be connected to the deep-drawn part by injection molding, gluing or the like, the ring part covering the end face or cutting edge of the side wall of the deep-drawn part, possibly also overlapping, in order to protect this edge against damage, moisture, etc.
- the ring part is made as a cup-shaped molded part from cardboard or cardboard composite with a bottom and a side wall, the bottom of which is partially punched out to form the grip edge and which conversely is placed on the deep-drawn part with its side wall overlapping on the outside and is connected to the side wall of the deep-drawn part by gluing or heat sealing.
- the ring part and thus the entire 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.
- the cup-shaped molded part forming the ring part engages over the deep-drawn part like a slip lid. After the assembly, the deep-drawn part and the molded part are connected to one another in the region of the adjacent wall sections by means of adhesive, heat-sealing adhesive or the like. The two parts, which interlock with each other, result a dimensionally stable structure that easily withstands the forces that arise during use.
- cup-shaped molded part forming the ring part is formed on its essentially cylindrical wall inwards to form a double layer, wherein it overlaps the side wall of the deep-drawn part with the double-layer wall and is connected to it in this area.
- Another exemplary 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.
- 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.
- the edge of the handle that is subjected to the greatest stress is highly rigid due to the double layer, so that even with a small wall thickness of the starting material there is sufficient strength.
- the ring part made of cardboard or cardboard composite can be manufactured in different ways.
- the cup-shaped molded part forming the ring part can be produced by deep-drawing a cardboard or cardboard composite.
- the cup-shaped molded part forming the ring part can be produced from an essentially cylindrical sleeve made of cardboard or cardboard composite by crimping the wall of the sleeve on one end face up to the double layer and then bending the double-layered wall inwards, the double-layered wall forming the bottom with the Grip edge forms and the remaining single-layer, cylindrical wall of the sleeve is connected to the side wall of the deep-drawn part of the cover.
- the aforementioned process is based on a cylindrical sleeve, which inherently has good dimensional stability. This is retained in the cylindrical section which remains even after the shaping, while in the flanged and inwardly bent section which forms the grip edge, increased rigidity is obtained through the double layer.
- This manufacturing method furthermore makes it possible to provide the sleeve in its single-layer cylindrical section with a label, a print or the like on the outside before it is formed. This applies in particular to the section of the sleeve which remains cylindrical, since there are no forming forces which could damage the labeling or the printing.
- the ring part at its periphery at the transition between the bottom and the side wall can have an inwardly drawn, circumferential stacking step, which centers and fixes a similar type of packaging in the area of its bottom.
- the cover 2 consists of a deep-drawn part 3, which is made of a cardboard or cardboard composite board.
- the deep-drawn part 3 consequently has a bottom 4 and a substantially cylindrical side wall 5, the outline of the deep-drawn part 3 essentially corresponding to the inner contour of the sleeve 1, so that it can engage in the sleeve relatively well.
- the cover 2 has a ring part 6, which in the exemplary embodiment according to FIG. 1 consists of plastic and is sprayed onto the open cutting edge 7 of the deep-drawn part 3. It therefore has the ring part 6 an inner wall web 8 and an outer wall web 9, with which it engages over the cutting edge 7.
- the outer wall web 9 also forms a step 10 with which the ring part covers the open cutting edge 11 of the sleeve 1. At the same time, the step 10 serves as a limit stop when the cover 2 is placed on the sleeve 1.
- the ring part 6 also has a central opening 12 with the formation of a grip edge 13, which the user can grip behind with his fingers to lift off the cover 2 or again to put on.
- 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.
- the lid again consists of the deep-drawn part 3, which is constructed in the same way as in the exemplary embodiment according to FIG Fig. 1, however, the ring member 6 is designed differently.
- the deep-drawn part 3 consists of a cup-shaped molded part. This cup-shaped molded part is formed by the base 15 and the wall 16, which in the exemplary embodiment shown is bent inwards to form a double layer, the inner layer 17 lying 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 the grip edge is formed.
- 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.
- 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.
- FIG. 3 shows an embodiment which is simplified compared to FIG. 2, in which the double layer in the region of the side wall 16 and the retracted grip edge are dispensed with.
- Both embodiments according to FIGS. 2 and 3 can be produced by punching and deep drawing from a blank or from a ring, the embodiment according to FIG. 3 requiring additional bending processes to produce the grip edge 13 and the double layer 17.
- the same cup-shaped deep-drawn part 3 is again provided, while the Ring part is designed differently. 2 and 3, it has a cylindrical (circular-cylindrical, oval or rectangular) side wall 16, but the bottom 15 of the cup-shaped molded part is folded inwards to form the double layer 21.
- This molded part is produced from a cylindrical sleeve, the cross section of which corresponds to that of the side wall 16. This sleeve is first crimped so that the double layer 21 is formed, and then this double-layer region is bent inwards by approximately 90 °, so that the grip edge 13 is formed.
- the sleeve can be printed or labeled in the area of the outer side 28 of the cylindrical side wall before it is formed.

Abstract
Description
Die Erfindung betrifft eine dosenförmige Verpackung für insbesondere rieselfähige Produkte, bestehend aus einer bodenseitig geschlossenen Hülse aus Karton oder einem mehrschichtigen Verbund aus Karton und/oder Kunststoff und/oder Metall und einem in die Hülse einsetzbaren napfförmigen Deckel mit einem Boden, einer im wesentlichen zylindrischen, der Innenseite der Hülse anliegenden Seitenwand und einem oberen Ringteil, das außenseitig eine der Stirnseite der Hülse aufliegende Stufe und einen nach innen eingezogenen Griffrand aufweist.The invention relates to a can-shaped packaging for in particular free-flowing products, consisting of a bottom-closed sleeve made of cardboard or a multi-layer composite made of cardboard and / or plastic and / or metal and a cup-shaped lid which can be inserted into the sleeve and has a bottom, an essentially cylindrical, the inside of the sleeve adjacent side wall and an upper ring part which has on the outside a step lying on the end face of the sleeve and an inwardly retracted grip edge.
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 packaging is usually on the lid side by a sealed membrane and are closed after filling through their open bottom side 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 the membrane has been opened, such packaging includes a separate lid, which is usually made of plastic as an injection molded part.
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.
Der Erfindung liegt die Aufgabe zugrunde, eine Verpackung des eingangs genannten Aufbaus so auszubilden, daß eine einfache und vor allem kostengünstigere Entsorgung möglich ist.The invention has for its object to provide a packaging of the structure mentioned above so that a simple and, above all, less expensive disposal is possible.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, 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.This object is achieved in that the lid consists of a deep-drawn part made of cardboard or cardboard composite comprising its bottom and side wall and a separately produced ring part connected to the deep-drawn part.
Bei der erfindungsgemäßen Ausbildung besteht der größere Teil des Deckels -was das Volumen und das Gewicht betrifft- aus einem Karton bzw. Kartonverbund, der vergleichsweise geringe Entsorgungsgkosten versursacht, während das Ringteil ein vergleichsweise geringes Volumen und Gewicht aufweist. Dieses Ringteil läßt sich im Bedarfsfall auch problemlos von dem Tiefziehteil trennen und gesondert entsorgen. Durch die zweiteilige Ausbildung ist es möglich, den aus Boden und Seitenwand bestehenden Teil des Deckels durch Tiefziehen zu formen.In the embodiment according to the invention, the larger part of the lid — in terms of volume and weight — consists of a cardboard or cardboard composite, which causes comparatively low disposal costs, while the ring part has a comparatively small volume and weight. If necessary, this ring part can also be easily separated from the deep-drawn part and disposed of separately. The two-part design makes it possible to shape the part of the cover consisting of the bottom and side wall by deep drawing.
Das Ringteil kann aus Kunststoff bestehen und durch Anspritzen, Kleben oder dergleichen mit dem Tiefziehteil verbunden sein, wobei das Ringteil die Stirnseite bzw. Schnittkante der Seitenwand des Tiefziehteils abdeckt, ggf. auch übergreift, um diese Kante gegen Beschädigung, Feuchtigkeitszutritt etc. zu schützen.The ring part can be made of plastic and can be connected to the deep-drawn part by injection molding, gluing or the like, the ring part covering the end face or cutting edge of the side wall of the deep-drawn part, possibly also overlapping, in order to protect this edge against damage, moisture, etc.
In einer anderen Ausführungsform kann vorgesehen sein, daß das Ringteil als napfförmiges Formteil aus Karton oder Kartonverbund mit einem Boden und einer Seitenwand hergestellt ist, dessen Boden zur Bildung des Griffrandes teilweise ausgestanzt ist und das umgekehrt auf das Tiefziehteil dieses mit seiner Seitenwand außenseitig übergreifend aufgesetzt und mit der Seitenwand des Tiefziehteils durch Kleben oder Heißsiegeln verbunden ist.In another embodiment it can be provided that the ring part is made as a cup-shaped molded part from cardboard or cardboard composite with a bottom and a side wall, the bottom of which is partially punched out to form the grip edge and which conversely is placed on the deep-drawn part with its side wall overlapping on the outside and is connected to the side wall of the deep-drawn part by gluing or heat sealing.
Bei dieser Ausführungsform besteht also auch das Ringteil und somit der gesamte Deckel aus Karton oder einem Kartonverbund, so daß die gesamte Verpackung als sortenrein bezeichnet werden kann und sich folglich kostengünstig entsorgen läßt. Bei dieser Ausführungsform übergreift das das Ringteil bildende napfförmige Formteil das Tiefziehteil ähnlich einem Stülpdeckel. Nach dem Zusammenfügen werden Tiefziehteil und Formteil im Bereich der einander anliegenden Wandabschnitte durch Klebstoffangabe, Heißsiegelkleber oder dergleichen miteinander verbunden. Die beiden umgekehrt ineinander eingreifenden Teile ergeben ein formstabiles Gebilde, das auch den beim Gebrauch auftretenden Kräften problemlos Stand hält.In this embodiment, therefore, the ring part and thus the entire 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. In this embodiment, the cup-shaped molded part forming the ring part engages over the deep-drawn part like a slip lid. After the assembly, the deep-drawn part and the molded part are connected to one another in the region of the adjacent wall sections by means of adhesive, heat-sealing adhesive or the like. The two parts, which interlock with each other, result a dimensionally stable structure that easily withstands the forces that arise during use.
Vorzugsweise ist vorgesehen, daß das das Ringteil bildende napffömige Formteil an seiner im wesentlichen zylindrischen Wandung nach innen zur Doppellage umgeformt ist wobei es mit der doppellagigen Wandung die Seitenwand des Tiefziehteils übergreift und in diesem Bereich mit jener verbunden ist.It is preferably provided that the cup-shaped molded part forming the ring part is formed on its essentially cylindrical wall inwards to form a double layer, wherein it overlaps the side wall of the deep-drawn part with the double-layer wall and is connected to it in this area.
Bei dieser Ausführungsform 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 vor dem Umbug der Wandung gebildet. Die Schnittkante selbst liegt an der Innenseite und kann ggf. von dem Boden des napffömigen Formteils abgedeckt sein.In this embodiment, it is avoided that a cut edge is exposed on the end face of the wall of the molded part forming the ring part, which cutting edge would have to be covered; rather, in this embodiment the end edge is formed before the wall is bent. The cutting edge itself lies on the inside and can optionally be covered by the bottom of the cup-shaped molded part.
Ein weiteres 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.Another exemplary 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 that is subjected to the greatest stress is highly rigid due to the double layer, so that even with a small wall thickness of the starting material there is sufficient strength.
Das Ringteil aus Karton oder Kartonverbund läßt sich auf verschiedene Weise fertigen. So kann das das Ringteil bildende napfförmige Formteil durch Tiefziehen einer Platine aus Karton oder Kartonverbund hergestellt sein.The ring part made of cardboard or cardboard composite can be manufactured in different ways. For example, the cup-shaped molded part forming the ring part can be produced by deep-drawing a cardboard or cardboard composite.
Stattdessen kann das das Ringteil bildende napfförmige Formteil aus einer im wesentlichen zylindrischen Hülse aus Karton oder Kartonverbund durch Einbördeln der Wandung der Hülse an deren einer Stirnseite bis zur Doppellage und anschließendes Umbiegen der doppellagigen Wandung nach innen hergestellt sein, wobei die doppellagige Wandung den Boden mit dem Griffrand bildet und die übrige einlagige, zylindrische Wandung der Hülse mit der Seitenwand des Tiefziehteils des Deckels verbunden ist.Instead, the cup-shaped molded part forming the ring part can be produced from an essentially cylindrical sleeve made of cardboard or cardboard composite by crimping the wall of the sleeve on one end face up to the double layer and then bending the double-layered wall inwards, the double-layered wall forming the bottom with the Grip edge forms and the remaining single-layer, cylindrical wall of the sleeve is connected to the side wall of the deep-drawn part of the cover.
Das vorgenannte Verfahren geht von einer zylindrischen Hülse aus, die schon von Haus aus eine gute Formstabilität besitzt. Diese wird in dem auch nach dem Umformen verbleibenden zylindrischen Abschnitt beibehalten, während in dem eingebördelten und nach innen umgebogene Abschnitt, der den Griffrand bildet, eine erhöhte Steifigkeit durch die Doppellage erhalten wird.The aforementioned process is based on a cylindrical sleeve, which inherently has good dimensional stability. This is retained in the cylindrical section which remains even after the shaping, while in the flanged and inwardly bent section which forms the grip edge, increased rigidity is obtained through the double layer.
Dieses Herstellungsverfahren gibt weiterhin die Möglichkeit, die Hülse in ihrem einlagigen zylindrischen Abschnitt vor dem Umformen außenseitig mit einer Etikettierung, einem Druck od. dgl. zu versehen. Dies gilt insbesondere für den zylindrisch bleibenden Abschnitt der Hülse, da dort keinerlei Umformkräfte wirken, welche die Etikettierung oder den Druck beschädigen könnten.This manufacturing method furthermore makes it possible to provide the sleeve in its single-layer cylindrical section with a label, a print or the like on the outside before it is formed. This applies in particular to the section of the sleeve which remains cylindrical, since there are no forming forces which could damage the labeling or the printing.
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 with the can-shaped packaging with a plastic lid is known per se, even with the packaging designed according to the invention, the ring part at its periphery at the transition between the bottom and the side wall can have an inwardly drawn, circumferential stacking step, which centers and fixes a similar type of packaging in the area of its bottom.
Nachstehend ist die Erfindung anhand mehrerer in der Zeichnung wiedergegebener Ausführungsbeispiele beschrieben. In der Zeichnung zeigen:

The packaging shown in FIGS. 1 and 2 has a
Bei dem Ausführungsbeispiel gemäß Fig. 1 besteht der Deckel 2 aus einem Tiefziehteil 3, das aus einer Karton oder Kartonverbund-Platine hergestellt ist. Das Tiefziehteil 3 weist folglich 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 Deckel 2 ein Ringteil 6 auf, das bei dem Ausführungsbeispiel gemäß Fig. 1 aus Kunststoff besteht und auf die offene Schnittkante 7 des Tiefziehteils 3 aufgespritzt ist. Es weist deshalb das Ringteil 6 einen inneren Wandsteg 8 und einen äußeren Wandsteg 9 auf, mit denen es die Schnittkante 7 übergreift. Der äußere Wandsteg 9 bildet zugleich eine Stufe 10, mit der das Ringteil die offene Schnittkante 11 der Hülse 1 abdeckt. Zugleich dient die Stufe 10 als Begrenzungsanschlag beim Aufsetzen des Deckels 2 auf die Hülse 1. Das Ringteil 6 weist ferner eine zentrale Öffnung 12 unter Bildung eines Griffrandes 13 auf, der vom Benutzer mit den Fingern hintergriffen werden kann, um den Deckel 2 abzuheben oder wieder aufzusetzen.1, the
Schließlich weist der Boden 4 des Tiefziehteils 3 im mittleren Bereich eine Vertiefung 14 auf, die vornehmlich der Versteifung des scheibenförmigen Bodens 4 dient.Finally, the
Bei dem Ausführungsbeispiel gemäß Fig. 2 besteht der Deckel wiederum aus dem Tiefziehteil 3, das in gleicher Weise aufgebaut ist, wie bei dem Ausführungsbeispiel gemäß Fig. 1, hingegen ist das Ringteil 6 anders gestaltet. Es besteht nämlich wie das Tiefziehteil 3 aus einem napfförmigen Formteil. Dieses napfförmige Formteil wird gebildet von dem Boden 15 und der Wandung 16, die beim gezeigten Ausführungsbeispiel nach innen zur Doppellage umgebogen ist, wobei die innere Lage 17 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 der Griffrand 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.In the exemplary embodiment according to FIG. 2, the lid again consists of the deep-drawn
Bei beiden Ausführungsformen ist der Deckel 2 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.In both embodiments, the
Figur 3 zeigt ein gegenüber Fig. 2 vereinfachtes Ausführungsbeispiel, bei dem auf die Doppellage im Bereich der Seitenwand 16 und auf den eingezogenen Griffrand verzichtet ist. Beide Ausführungsformen nach Fig. 2 und 3 lassen sich durch Ausstanzen und Tiefziehen aus einer Platine oder aus einem Ring herstellen, wobei die Ausführungsform nach Fig. 3 zur Erzeugung des Griffrandes 13 und der Doppellage 17 zusätzliche Biegevorgänge erfordert.FIG. 3 shows an embodiment which is simplified compared to FIG. 2, in which the double layer in the region of the
Bei dem Ausführungsbeispiel nach Fig. 4 ist wiederum das gleiche napfförmige Tiefziehteil 3 vorgesehen, während das Ringteil anders gestaltet ist. Es weist zwar wie die vorangehenden Ausführungsbeispiele nach Fig. 2 und 3 eine zylindrische (kreiszylindrische, ovale oder rechteckige) Seitenwand 16 auf, jedoch ist der Boden 15 des napfförmigen Formteils nach innen zur Doppellage 21 umgelegt. Dieses Formteil wird aus einer zylindrischen Hülse hergestellt, deren Querschnitt demjenigen der Seitenwand 16 entspricht. Diese Hülse wird zunächst eingebördelt, so daß die Doppellage 21 entsteht, und anschließend dieser doppellagige Bereich nach innen um etwa 90° umgebogen, so daß der Griffrand 13 entsteht. Bei dieser Ausführung kann die Hülse bereits vor dem Umformen im Bereich der Außenseite 28 der zylindrischen Seitenwand bedruckt oder etikettiert sein.In the embodiment of FIG. 4, the same cup-shaped deep-drawn
