Abstract

The tin can has an end section (2) with an opening. The section is increased in size conically outwards towards the upper end (12). The edge of the foil (3) is fastened to the end section. The conical part may be formed by a contraction (21), so that the external diameters of end and central can sections are the same. The opening angle ( alpha ) in the conical end section can be approx. 7 deg. The top edge of the can jacket is flanged outwards. The foil consists of aluminium, and has a grip to peel it off. The outer diameter of the can base is smaller by the size of the flanging, than the inner diameter of the top end section edge.

Description

Die Erfindung betrifft eine Dose, insbesondere eine Blechdose, wie sie im Oberbegriff des Patentanspruches 1 näher angegeben ist.The invention relates to a can, in particular a tin can, as specified in the preamble of claim 1.

Derartige Dosen werden für die Verpackung von Lebensmitteln, beispielsweise zum Verpacken von gemahlenem Kaffee, Pulver zum Bereiten von Getränken oder dergleichen eingesetzt. Solche Dosen werden unter anderem mit einem sogenannten "Peel-Off"-Verschluß versehen, wobei in dem aus Blech (Weißblech) bestehenden Deckel der Dose eine Öffnung eingestanzt ist, die anschließend mit einer Folie überdeckt wird, die an dem die Öffnung umgebenden Rand des Deckels angesiegelt wird. Durch Abziehen der Folie kann der Verbraucher die Dose dann leicht öffnen.Such cans are used for the packaging of food, for example for packaging ground coffee, powder for making beverages or the like. Such cans are provided, inter alia, with a so-called "peel-off" closure, an opening being punched into the can's cover made of sheet metal (tinplate), which is then covered with a film which on the edge of the opening surrounding the opening Lid is sealed. The consumer can then easily open the can by pulling off the film.

Bei diesem aus dem Stand der Technik bekannten Dosen ist nachteilig, daß bei der Herstellung der zu dem Verschluß verwendeten Deckeln ein hoher Materialausschuß anfällt. Der Deckel, der an dem Mantel der Dose durch Rollen bzw. Umbördelung befestigt wird, muß zuvor durch Stanzen mit der Öffnung versehen werden. Das ausgestanzte Teil ist Abfallmaterial und nicht mehr weiter verwendbar. Weiterhin ist nachteilig, daß die ausgestanzten Öffnungen einen scharfen Rand haben, so daß für den Verbraucher eine Verletzungsgefahr besteht, wenn er mit einem Löffel oder dergleichen in die Dose hineingreift. Soll dieses verhindert werden, muß der Rand der Öffnung nachbearbeitet werden. Diese Probleme entstehen in gleicher Weise bei anderen Dosen, bei denen der Mantel nicht aus Blech, sondern z.B. aus einem Papprohr besteht, die aber ebenfalls in herkömmlicher Weise mit Blechdeckeln verschlossen sind.This cans known from the prior art has the disadvantage that a high material scrap is incurred in the manufacture of the lids used for the closure. The lid, which is attached to the casing of the can by rolling or flanging, must first be provided with the opening by punching. The punched-out part is waste material and can no longer be used. Another disadvantage is that the punched openings have a sharp edge, so that there is a risk of injury to the consumer if he reaches into the can with a spoon or the like. If this is to be prevented, the edge of the opening must be reworked. These problems arise in the same way with other cans in which the casing is not made of sheet metal, but e.g. consists of a cardboard tube, but which are also closed in a conventional manner with sheet metal lids.

Aufgabe der Erfindung ist dementsprechend, eine für Lebensmittelverpackungen geeignete Dose, insbesondere Blechdose, die eine mit einer abziehbaren Folie verschlossene Öffnung aufweist, so auszugestalten, daß die Nachteile der herkömmlichen Dosen mit einem solchen Verschluß vermieden werden und insbesondere der Materialaufwand verringert und die Zahl der Herstellungsschritte verkleinert wird.The object of the invention is accordingly to design a can suitable for food packaging, in particular a tin can, which has an opening closed with a removable film, in such a way that the disadvantages of conventional cans with such a closure are avoided and in particular the material expenditure is reduced and the number of manufacturing steps is reduced is reduced.

Diese Aufgabe wird mit einer Dose gelöst, die die im Patentanspruch 1 angegebenen Merkmale aufweist. Weitere, vorteilhafte Ausgestaltungen der Erfindung und ein bevorzugtes Verfahren zur Herstellung einer solchen Dose sind in den Unteransprüchen angegeben.This object is achieved with a can, which has the features specified in claim 1. Further advantageous embodiments of the invention and a preferred method for producing such a can are specified in the subclaims.

Der Grundgedanke der Erfindung besteht darin, den bisher verwendeten, mit der ausgestanzten Öffnung versehenen Blechdeckel völlig durch eine abziehbare Folie zu ersetzen, so daß also die gesamte obere Fläche der Dose von der Folie verschlossen ist. Da die Folie aber auf der Innenseite der Dose angesiegelt werden muß, müßte die Folie ganz nach oben umgebogen sein, so daß sie einen U-förmigen Querschnitt besitzt. Eine so gestaltete Folie läßt sich aber nur mit großen Schwierigkeiten an den Innenrand der Dose ansiegeln, da die Dosen im allgemeinen gewisse Maßtoleranzen aufweisen und deren Querschnittsflächen auch nicht völlig kreisrund sind. Es wäre daher ein Werkzeug notwendig, das den Rand der Folie mit der Siegelbeschichtung an den Dosenmantel anrollt oder von innen her anpreßt. Derartige Werkzeuge sind aber aufwendig und teuer. Die Erfindung sieht daher vor, daß sich die Dose in ihrem oberen Endabschnitt nach außen hin konisch erweitert, und daß die Folie in diesem Endabschnitt angesiegelt wird. Das Werkzeug, mit dem das Ansiegeln der Folie durchgeführt wird, weist eine entsprechende Konizität auf, so daß das Ansiegeln durch einen in Axialrichtung der Dose wirkenden Druck bewerkstelligt werden kann. Der konische Endabschnitt der Dose wird vorzugsweise dadurch gebildet, daß die Dose dort mit einem Einzug versehen wird. Das hat den Vorteil, daß der konische Endabschnitt einen gegenüber der übrigen Dose verkleinerten Durchmesser hat, so daß sein oberes Ende nicht über den Mittelteil oder den Boden der Dose nach außen hinausragt. Dies ist für die Stapelfähigkeit und Verpackbarkeit der Dosen von Bedeutung.The basic idea of the invention is to completely replace the previously used sheet metal lid provided with the punched-out opening by a removable film, so that the entire upper surface of the can is closed by the film. However, since the film must be sealed on the inside of the can, the film should be bent all the way up so that it has a U-shaped cross section. However, a film designed in this way can only be sealed to the inner edge of the can with great difficulty, since the cans generally have certain dimensional tolerances and their cross-sectional areas are also not completely circular. It would therefore be necessary to have a tool that rolls the edge of the film with the sealing coating onto the can jacket or presses it from the inside. However, such tools are complex and expensive. The invention therefore provides that the can widens conically in its upper end section and that the film is sealed in this end section. The tool with which the sealing of the film is carried out has a corresponding taper, so that the sealing can be accomplished by a pressure acting in the axial direction of the can. The conical end section of the can is preferably formed by providing the can with a draw-in there. This has the advantage that the conical end section has a diameter which is smaller than that of the other can, so that its upper end does not protrude outwards beyond the middle part or the bottom of the can. This is important for the stackability and packability of the cans.

Bei der Herstellung eines solchen Verschlusses wird vorzugsweise eine Folie verwendet, die hutförmig gestaltet ist. wobei der Durchmesser der Folie im Bereich der "Krempe" etwas größer ist als der Durchmesser der Dose an ihrem oberen Ende. Wird die so gestaltete Folie mit einem leicht konischen Werkzeug oben in den konischen Endabschnitt der Dose eingeführt, so klappt die "Krempe" der Folie nach oben weg und legt sich an den konischen Endabschnitt der Dose an.In the production of such a closure, a film is preferably used which is hat-shaped. the diameter of the film in the area of the "brim" is slightly larger than the diameter of the can at its upper end. If the film designed in this way is inserted into the conical end section of the can with a slightly conical tool, the "brim" of the film folds upward and lies against the conical end section of the can.

Um die Stapelbarkeit und Versandfähigkeit der Dosen zu erhöhen, kann ferner vorgesehen sein, daß die Dose am Boden einen verkleinerten Innendurchmesser besitzt, damit die außenliegende Umbördelung nicht über die Mantelfläche der Dose hinausragt sondern auch am Boden der Außendurchmesser der Dose gleich groß ist.In order to increase the stackability and dispatchability of the cans, it can further be provided that the can has a reduced inner diameter at the bottom, so that the outer flanging does not protrude beyond the outer surface of the can but is also of the same size on the bottom of the outer diameter of the can.

Vorzugsweise ist der Boden so gestaltet, daß sein Außendurchmesser geringfügig Kleiner ist als der Innendurchmesser des oberen Randes des konischen Endabschnitts, so daß jeweils der Dosenboden in die Öffnung einer darunter befindlichen Dose eingesetzt werden kann, was die Stapelbarkeit verbessert.The base is preferably designed in such a way that its outer diameter is slightly smaller than the inner diameter of the upper edge of the conical end section, so that in each case the bottom of the can can be inserted into the opening of a can underneath, which improves stackability.

Im folgenden wird die Erfindung anhand des in den Figuren dargestellten Ausführungsbeispiels beschrieben und näher erläutert.The invention is described and explained in more detail below on the basis of the exemplary embodiment illustrated in the figures.

1, the can body 1 consists of a jacket 11, which is flanged at its upper end 12 to the outside. The upper end section 2 of the can body is conical in that a feed 21 is attached, for example by rolling. In the area of the intake, the diameter of the can body is somewhat reduced compared to the casing area 11, so that the diameter of the upper end 12 of the can body is as large as in the casing area.

In der Fig. 2 ist der konische Endabschnitt 2 der mit der Folie 3 verschlossenen Dose vergrößert dargestellt. Die Dose öffnet sich von dem Einzug 21 nach oben; der Winkel zwischen dem konischen Endbereich 2 und der Dosenachse beträgt entsprechend der Darstellung von Fig. 2 etwa 7°. In Fig. 2 ist weiter erkennbar, daß die Folie 3 an dem Innenteil des konischen Endbereiches 2 angesiegelt ist und der Bord nach außen umgelegt und angebördelt ist.2, the conical end section 2 of the can closed with the film 3 is shown enlarged. The can opens up from the feeder 21; the angle between the conical end region 2 and the can axis is approximately 7 ° as shown in FIG. 2. In Fig. 2 it can also be seen that the film 3 is sealed to the inner part of the conical end region 2 and the board is folded over and flanged.

In der Fig. 3 ist im vergrößerten Ausschnitt der Randbereich des Dosenbodens dargestellt. Es ist erkennbar, daß der Mantel der Dose in der Nähe des Dosenbodens so weit verjüngt ist, daß die Umbördelung 40 nicht über den Mantel 11 der Dose hinaussteht; insbesondere ist die Gestaltung derart, daß der Dosenboden mit seiner Umbördelung in das obere Ende des konischen Endabschnitts (2) einer anderen, gleichen Dose hineinpaßt.3 shows the enlarged area of the edge area of the can base. It can be seen that the casing of the can is tapered so far in the vicinity of the can bottom that the flange 40 does not protrude beyond the casing 11 of the can; in particular, the design is such that the can bottom with its flanging fits into the upper end of the conical end section (2) of another, same can.

Die Fig. 4 zeigt die zum Verschluß dienende Folie 3 im Querschnitt. Die Folie besteht vorzugsweise aus Aluminium und ist an ihrer Unterseite mit einer Siegelbeschichtung 34 versehen. Ihr Querschnitt ist hutförmig, wobei der Außendurchmesser größer ist als der Außendurchmesser der Dose an ihrem oberen Ende. Auf ihrer Unterseite ist sie mit einer Siegel-Beschichtung 34 versehen. Zum Ansiegeln der Folie wird die Dose mit der hutförmigen Folie versehen oder die in die notwendige hutförmige Form gebrachte Folie wird auf ein konisches, beheizbares Werkzeug aufgelegt und von unten her mit diesem Werkzeug in den konischen Endabschnitt der Dose eingeführt und unter Druck an die Doseninnenseite angesiegelt. Dabei klappt der Randbereich 35 (die "Krempe") der Folie ab und legt sich an die Innenfläche der Dose an.Fig. 4 shows the film 3 used for closure in cross section. The film is preferably made of aluminum and is provided with a sealing coating 34 on its underside. Their cross section is hat-shaped, the outer diameter being larger than the outer diameter of the can at its upper end. It is provided with a sealing coating 34 on its underside. To seal the film, the can is provided with the hat-shaped film or the film brought into the necessary hat-shaped form is placed on a conical, heatable tool and inserted from below with this tool into the conical end section of the can and sealed under pressure on the inside of the can . The edge region 35 (the "brim") of the film folds away and lies against the inner surface of the can.

In Fig. 4 ist erkennbar, daß an der nach außen liegenden Seite der Folie in deren Mittelteil eine Handhabe 32 angebracht sein kann, mit der die Folie dann nach außen abgezogen werden kann.In Fig. 4 it can be seen that a handle 32 can be attached to the outward side of the film in the central part, with which the film can then be removed to the outside.
