Abstract

1. A container with a body (1), which is wound from a rectangular board blank and at least the top of which has a beaded edge (8) that projects inwards and supports on the inside a flat lid disc (6), part of which is designed as a pulling device for opening the pack, wherein this pulling device takes the form of a pull tab that is an extension (9) to the flat lid disc (6) and is folded over towards the middle of the lid disc, this folded section resting on the top of the lid disc and thus being wedged under the beaded edge (8) and wherein the pull tab extends towards the middle of the lid disc along two lines of weakening (11, 12) in such a way that when the pull tab is pulled upwards it separates from the rest of the lid disc towards the middle of the lid disc along the lines of weakening and that the outer circumference of the lid disc is reduced to the inner circumference of the beaded edge so that the lid disc slips out from under the beaded edge.

Description

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen einer Dose mit einem aus einem rechteckigen Kartonzuschnitt oder dgl. gewickelten Mantel, einem Boden und einem Deckel, bei dem der Mantel ein- oder mehrlagig auf einem dessen Querschnittsform angepaßten Dorn gewickelt wird.The invention relates to a method for producing a can with a jacket wound from a rectangular cardboard blank or the like. A bottom and a lid, in which the jacket is wound in one or more layers on a mandrel adapted to its cross-sectional shape.

Insbesondere sehr flache Dosen werden im allgemeinen mit einem zweiteiligen Dosenmantel, nämlich mit getrenntem Unter- und Oberteil, hergestellt.In particular, very flat cans are generally produced with a two-part can jacket, namely with a separate lower and upper part.

Diese Herstellung ist aber sehr aufwendig und teuer und bedingt einen verhältnismäßig hohen Materialeinsatz.However, this production is very complex and expensive and requires a relatively high amount of material.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu schaffen, mit dem Dosen der genannten Art einfach und preisgünstig herstellbar sind.The invention has for its object to provide a method with which cans of the type mentioned are simple and inexpensive to manufacture.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das untere Ende des Dosenmantels nach innen eingebördelt und ein Boden in die Dose eingelegt wird, und nach dem Befüllen der Dose mit dem zu verpackenden Gut eine Deckelscheibe auf das Füllgut aufgelegt und dann der obere Dosenrand bis zur Anlage an diese Deckelscheibe eingebördelt wird.This object is achieved in that the lower end of the can jacket is crimped inwards and a bottom is placed in the can, and after the can has been filled with the goods to be packed, a cover plate is placed on the contents and then the upper edge of the can up to the system is crimped onto this cover plate.

Durch dieses Verfahren wird es ermöglicht, eine aus lediglich drei Teilen bestehende Dose herzustellen, die vollständig mit Füllgut angefüllt ist und keinen Hohlraum aufweist.This process makes it possible to produce a can consisting of only three parts, which is completely filled with filling material is and has no cavity.

Darüber hinaus hat die nach dem erfindungsgemäßen Verfahren hergestellte Dose ohne weitere Maßnahmen einen Originalitätsverschluß, da sie nur unter zumindest teilweiser Zerstörung des Deckels geöffnet werden kann.In addition, the can produced by the method according to the invention has a tamper-evident seal without further measures, since it can only be opened with at least partial destruction of the lid.

Aus dem DE-GM 77 39 530 ist zwar eine Runddose mit einem einteiligen Mantel, einer Boden- und einer Deckelscheibe bekannt. Das Herstellungsverfahren weist jedoch einen ganz erheblichen Unterschied auf. Bei dem bekannten Verfahren wird nämlich zuerst am oberen und unteren Ende der Dose ein Rand nach innen umgebördelt. Sodann wird eine Bodenscheibe eingelegt und das Füllgut eingebracht, das aber nicht bis zum oberen Bördelrand reicht. Nur durch die Belassung eines Freiraumes ist es möglich, die obere Deckelscheibe nachträglich einzusprengen.From DE-GM 77 39 530 a round box with a one-piece jacket, a base plate and a cover plate is known. However, the manufacturing process has a very significant difference. In the known method, an edge is first flanged inwards at the upper and lower end of the can. A base plate is then inserted and the filling material is introduced, which, however, does not reach the upper edge of the flange. Only by leaving a free space is it possible to retrofit the upper cover plate.

Für zahlreiche Füllgüter ist die Belassung eines freien Kopfraumes aber äußerst unzweckmäßig. Mit dem erfindungsgemäßen Verfahren ist es dagegen möglich, eine Dose der genannten Art zu schaffen, die keinen freien Kopfraum oberhalb des Füllgutes und unterhalb der Deckelscheibe aufweist.For numerous filling goods, however, leaving a free head space is extremely inappropriate. In contrast, with the method according to the invention it is possible to create a can of the type mentioned which has no free head space above the filling material and below the cover plate.

Die Deckelscheibe kann sich zur Vereinfachung des Verschließvorganges während des Umbördelns des oberen Dosenrandes an dem Füllgut abstützen.To simplify the sealing process, the cover plate can be supported on the filling material during the flanging of the upper edge of the can.

Gemäß der Erfindung kann der Boden der Dose als ebene Scheibe ausgebildet sein und auf den nach innen eingebördelten unteren Dosenrand aufgelegt werden.According to the invention, the bottom of the can can be designed as a flat disc and placed on the inwardly crimped lower edge of the can.

Es ist jedoch auch möglich, daß der Boden der Dose mit einem nach unten abgebogenen Randstreifen versehen wird, der mit dem nach innen und oben abgebogenen unteren Rand des Dosenmantels verpreßt wird.However, it is also possible for the bottom of the can to be provided with a downwardly bent edge strip which is pressed with the inwardly and upwardly bent lower edge of the can jacket.

Dadurch ist es möglich, eine sehr stabile Dose herzustellen, die an der Unterseite darüber hinaus sehr dicht ausgebildet werden kann. ' IThis makes it possible to produce a very stable can, which can also be made very dense on the underside. 'I

Ebenfalls sehr vorteilhaft ist es, wenn gemäß der Erfindung der untere Rand des Dosenmantels beim Verpressen mit dem Randstreifen des Bodens gleichzeitig mit einem nach innen gerichteten Absatz versehen wird, der sich über den gesamten Umfang des Dosenmantels erstreckt.It is also very advantageous if, according to the invention, the lower edge of the can jacket when pressed with the edge strip of the bottom is simultaneously provided with an inward-facing heel that extends over the entire circumference of the can jacket.

Hierdurch wird in verhältnismäßig einfacher Weise erreicht, daß mehrere Dosen übereinander gestapelt werden können, ohne daß dabei die Gefahr besteht, daß der Stapel verrutscht und umfällt.As a result, it is achieved in a relatively simple manner that several cans can be stacked one above the other without the risk of the stack slipping and falling over.

Ein derartiger Stapelrand kann gemäß der Erfindung auch dadurch hergestellt werden, daß der untere Rand des Dosenmantels beim Verpressen mit dem Randstreifen des Bodens gleichzeitig nach außen aufgeweitet wird, wodurch ein außerhalb des Dosenumfanges liegender Stapelrand gebildet wird, mit dem die Dose auf einer darunter stehenden aufzustehen vermag.Such a stacking edge can also be produced according to the invention in that the lower edge of the can jacket is simultaneously widened outwards when pressed together with the edge strip of the base, thereby forming a stacking edge lying outside the can circumference, with which the can can stand up on an underlying one can

Da der untere Rand der Dose wegen des eingesetzten Bodens verhältnismäßig stark ausgebildet ist, kann bei dieser Ausgestaltung beim Stapeln vieler Dosen übereinander keine unbeabsichtigte Aufweitung eines Dosenabschnittes eintreten. Somit wird eine weitgehende Dosenschonung erzielt.Since the lower edge of the can is relatively strong due to the base used, in this embodiment, when a large number of cans are stacked on top of one another, no unintended widening of a can section can occur. This means that the can is largely protected.

Eine erfindungsgemäß hergestellte Dose ist vorteilhafterweise derart ausgestaltet, daß an der Deckelscheibe ein Ansatz angeformt ist; der über den Scheibendurchmesser hinausragt und gegen das Scheibenzentrum hin umgefaltet ist, auf der Oberseite der Deckelscheibe aufliegt und sich in einem Streifen fortsetzt, der ins Innere der Deckelscheibe hineinragt und durch zwei verhältnismäßig kurze Schnittlinien von dieser an zwei Seiten abgetrennt ist.A can manufactured according to the invention is advantageously designed in such a way that an extension is formed on the cover plate; which protrudes beyond the disc diameter and is folded towards the disc center, rests on the top of the cover disc and continues in a strip that protrudes into the inside of the cover disc and is separated from it on two sides by two relatively short cutting lines.

Hierdurch ist ein leichtes Öffnen der Dose möglich, bei dem jedoch zwangsläufig ein teilweises Zerstören der Deckelscheibe erfolgt. Beim Hochziehen des Ansatzes werden dieser und der mit diesem verbundene Streifen unter dem oberen Bördelrand des Dosenmantels hervorgezogen. Um jedoch auch ein Hervorziehen der gesamten Deckelscheibe zu bewirken, muß ein in der Verlängerung des Streifens liegender Abschnitt der Deckelscheibe losgetrennt werden, damit diese ihren Außenumfang auf das Maß des Innenumfangs des Bördelrandes verringern kann.This enables the can to be opened easily, but inevitably leads to a partial destruction of the cover plate. When pulling up the attachment, this and the strip connected to it are pulled out from under the upper flanged edge of the can jacket. However, in order to also pull out the entire cover plate, a section of the cover plate lying in the extension of the strip must be separated so that it can reduce its outer circumference to the size of the inner circumference of the flange edge.

Da diese teilweise Zerstörung auch nach einem eventuellen Wiederanbringen der Deckelscheibe sichtbar ist, weist die so ausgestaltete Dose einen Originalitätsverschluß auf.Since this partial destruction is visible even after a possible reinstallation of the cover plate, the can designed in this way has one Tamper evident closure.

In der Zeichnung ist die Erfindung anhand von drei Ausführungsbeispielen dargestellt. Dabei zeigen:

  • Fig. 1 einen Schnitt durch eine am oberen und unteren Rand eingebördelte Dose mit Bodenscheibe und Deckelscheibe,
  • Fig. 2 eine Draufsicht auf die Deckelscheibe,
  • Fig. 3 einen Schnitt durch die Dose, deren unterer Rand mit dem Ansatz eines Bodens verpreßt ist,
  • Fig. 4 einen Schnitt durch eine Dose, deren unterer mit dem Boden verpreßter Rand einen nach innen gerichteten Absatz aufweist und
  • Fig. 5 einen Schnitt durch eine Dose, deren unterer Rand nach außen aufgeweitet ist und dadurch einen Stapelrand aufweist.
In the drawing, the invention is illustrated using three exemplary embodiments. Show:
  • 1 shows a section through a box flanged at the top and bottom with a base plate and cover plate,
  • 2 is a plan view of the cover plate,
  • 3 shows a section through the can, the lower edge of which is pressed with the attachment of a base,
  • Fig. 4 shows a section through a can, the lower edge pressed with the bottom has an inwardly directed paragraph and
  • Fig. 5 shows a section through a can, the lower edge of which is widened outwards and thereby has a stacking edge.

Mit 1 ist in Fig. 1 ein Dosenmantel bezeichnet, der an seinem unteren Rand 2 nach innen eingebördelt ist, wodurch eine Rolle 3 entstanden ist. Auf dieser Rolle 3 liegt eine lose in die Dose eingelegte Bodenscheibe 4 auf. Mit 5 ist ein nicht näher bezeichnetes Füllgut bezeichnet, das auf der Bodenscheibe 4 aufliegt. Auf diesem Füllgut stützt sich eine Deckelscheibe 6 ab, gegen die der obere Rand 7 des Dosenmantels 1 bis zu seiner Anlage an der Deckelscheibe eingerollt ist. Der so gebildete Bördelrand 8 hält die Deckelscheibe und preßt sie gegen das Füllgut.1 in FIG. 1 denotes a can jacket which is crimped inwards at its lower edge 2, as a result of which a roll 3 has been created. On this roller 3 is a loosely inserted into the can bottom plate 4. With 5 is a filler, not specified, which rests on the base plate 4. A lid disk 6 is supported on this filling material, against which the upper edge 7 of the can jacket 1 is rolled up until it abuts the lid disk. The flanged edge 8 thus formed holds the cover plate and presses it against the filling material.

An der Deckelscheibe 6 ist ein Ansatz 9 angeformt, der über den Scheibendurchmesser hinausragt und gegen das Scheibenzentrum hin umgefaltet ist und auf der Oberseite der Deckelscheibe liegt. Der Ansatz 9 setzt sich in einem Streifen 10 fort (Fig. 2), der ins Innere der Deckelscheibe 6 hineinragt und durch zwei Schnittlinien 11, 12 von dieser abgetrennt ist.A lug 9 is formed on the cover plate 6, which projects beyond the plate diameter and is folded over towards the center of the plate and lies on the top of the cover plate. The approach 9 continues in a strip 10 (FIG. 2) which protrudes into the inside of the cover plate 6 and is separated from it by two cutting lines 11, 12.

Zum Öffnen der Dose wird der Ansatz 9 ergriffen und nach oben gezogen. Dadurch werden dieser und der Steifen 10 unter dem Bördelrand 8 hervorgezogen. Die Deckelscheibe 6 löst sich jedoch erst vom Bördelrand, wenn ein in der Verlängerung des Streifens 10 liegender Abschnitt 13 in der Verlängerung der Schnittlinien 11, 12 abgetrennt ist. Erst dann ist es möglich, daß sich beim Hochziehen der Außenumfang der Deckelscheibe bis auf den Innenumfang des Bördelrandes zusammenzieht und die Deckelscheibe unter dem Bördelrand herausrutschen kann.To open the can, the attachment 9 is gripped and pulled upwards. As a result, this and the stiffener 10 emerge from the flanged edge 8 drawn. However, the cover plate 6 only detaches from the flanged edge when a section 13 lying in the extension of the strip 10 is separated in the extension of the cutting lines 11, 12. Only then is it possible for the outer circumference of the cover plate to contract up to the inner circumference of the flanged edge when pulling up, and for the cover plate to slide out from under the flanged edge.

Somit ist die Dose gleichzeitig mit einem Originalitätsverschluß versehen, da ein Öffnen nur unter teilweiser Zerstörung der Deckelscheibe möglich ist.Thus, the can is also provided with a tamper-evident closure, since opening is only possible by partially destroying the cover plate.

Beim Ausführungsbeispiel nach Fig. 3 ist ein Boden 40 vorgesehen, der einen nach unten abgebogenen Randstreifen 41 aufweist. Der untere Rand 20 des Dosenmantels 21 ist nach innen und oben um den Randstreifen 41 herum umgebogen und mit diesem verpreßt.In the exemplary embodiment according to FIG. 3, a bottom 40 is provided which has an edge strip 41 bent downwards. The lower edge 20 of the can jacket 21 is bent inwards and upwards around the edge strip 41 and pressed with it.

Beim Ausführungsbeispiel nach Fig. 4 ist die Dose genauso ausgebildet wie beim Ausführungsbeispiel nach Fig. 3. Lediglich der untere Rand des Dosenmantels ist mit einem nach innen gerichteten Absatz 30 versehen, der beim Verpressen des Randes mit dem Randstreifen des Bodens gebildet wird. In diesen Absatz 30 vermag der obere Bördelrand 8 einer entsprechenden Dose einzugreifen, wodurch beim Übereinanderstapeln ein sicherer Halt der Dosen untereinander gewährleistet ist.In the exemplary embodiment according to FIG. 4, the can is designed in exactly the same way as in the exemplary embodiment according to FIG. 3. Only the lower edge of the can jacket is provided with an inwardly directed shoulder 30, which is formed when the edge is pressed together with the edge strip of the bottom. The upper flanged edge 8 of a corresponding can is able to intervene in this shoulder 30, as a result of which the cans are securely held one above the other when stacked on top of one another.

Die Dose gemäß Fig. 5 hat einen unteren Rand 20 des Dosenmantels 21, der beim Verpressen mit dem Randstreifen 41 des Bodens-40 nach außen aufgeweitet wurde. Dadurch wurde ein außerhalb des Dosenumfanges liegender Stapelrand 42 gebildet, mit dem die Dose auf eine darunter stehende aufsetzbar ist. Es wird dabei eine einwandfreie Justierung der Dosen erreicht.The can according to FIG. 5 has a lower edge 20 of the can jacket 21, which was widened outwards when pressed with the edge strip 41 of the bottom 40. As a result, a stacking edge 42 lying outside the can circumference was formed, with which the can can be placed on an underlying one. A perfect adjustment of the cans is achieved.
