Abstract

1. A process for producing a container (1) with a body that is wound from board or a similar material and is closed with a lid (7), in the course of which the top edge of the container body (2) is rolled, inwards in one or more stages and is then compressed to form a double flange (4), with one flange (5) extending vertically upwards to form the top end of the container body (2), while the second flange (6) projects radially inwards, wherein the lid (7) is made from metal, can be pulled open along a tear line and also has a flanged rim which is placed on and compressed with the flange (5) that extends vertically upwards.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Herstellen eines Behälters mit einem Mantel, der aus Karton od. dgl. gewickelt und mit einem Deckel verschlossen wird, wobei der obere Rand des Behältermantels in einer oder mehreren Stufen nach innen eingerollt und dann zu einer Doppelbördelung verpreßt wird, deren eine Bördelung senkrecht nach oben steht und das obere Ende des Behältermantels bildet, während die zweite Bördelung radial nach innen absteht.The invention relates to a method and a device for producing a container with a jacket that is wrapped in cardboard or the like and is closed with a lid, the upper edge of the container jacket being rolled inwards in one or more steps and then to double flanging is pressed, one flange is perpendicular upwards and forms the upper end of the container shell, while the second flange protrudes radially inwards.

Aus der GB-A-174 907 ist ein Behälter bekannt, der am oberen Rand mit einer Doppelbördelung versehen ist. Auf die radial nach innen abstehende Bördelung ist dabei eine Deckelscheibe aufgelegt, die sich mit ihrem Rand an der senkrecht nach oben stehenden Bördelung abzustützen vermag.From GB-A-174 907 a container is known which is provided with a double flange at the upper edge. In this case, a cover plate is placed on the flanging projecting radially inwards, the edge of which can be supported on the flare standing vertically upwards.

Ein derartig verschlossener Behälter ist aber nicht ausreichend dicht. Mit der Erfindung soll vorgeschlagen werden, einen Behälter zu schaffen, der eine große Dichtigkeit aufweist.Such a closed container is not sufficiently tight. The invention is intended to provide a container that has a high level of tightness.

Dies wird erfindungsgemäß dadurch erreicht, daß der Deckel aus Metall besteht, entlang einer Sollbruchlinie aufreißbar ist und ebenfalls einen Bördelrand aufweist, der auf die senkrecht nach oben stehende Bördelung aufgesetzt und mit dieser verpreßt wird.This is achieved according to the invention in that the cover is made of metal, can be torn open along a predetermined breaking line and also has a flanged edge which is placed on the flare standing vertically upwards and pressed with it.

Solche Deckel aus Metall mit Sollbruchlinie sind zwar generell insbesondere unter der Bezeichnung « Ring Pull bekannt. Sie haben sich in der Praxis bewährt, da sie einerseits den Behälter sehr dicht verschließen, andererseits aber ohne jedes Werkzeug leicht zu öffnen sind. Sie haben jedoch auch einen erheblichen Nachteil, der darin liegt, daß die Sollbruchlinie in einem Abstand vom Außenrand verläuft, wodurch beim Aufreißen ein freier Rand stehen bleibt, der ins Behälterinnere ragt.Such metal covers with a predetermined breaking line are generally known in particular under the name “ring pull”. They have proven themselves in practice, because on the one hand they seal the container very tightly, but on the other hand they are easy to open without any tools. However, they also have a considerable disadvantage, which is that the predetermined breaking line runs at a distance from the outer edge, as a result of which a free edge which projects into the interior of the container remains when it is torn open.

Durch diesen freien Rand, der äußerst scharfkantig ist, besteht eine erhebliche Verletzungsgefahr.This free edge, which is extremely sharp, poses a considerable risk of injury.

Es wurden in der Praxis Versuche unternommen, diese Verletzungsgefahr herabzusetzen.Attempts have been made in practice to reduce this risk of injury.

Bei einer in der Praxis bekanntgewordenen Lösung soll dies dadurch erreicht werden, daß oberhalb des beim Aufreißen entstehenden Randes ein weiterer Rand mit abgerundeter Kante angeordnet wird.In the case of a solution which has become known in practice, this is to be achieved in that a further edge with a rounded edge is arranged above the edge which arises when it is torn open.

Ein solcher mit zusätzlicher Kante ausgerüsteter Metalldeckel ist verhältnismäßig teuer und kann lediglich vor Berührung der oberen Kante der Bruchlinie schützen. Gerade diese obere Kante ist aber aufgrund der an der Deckeloberseite angebrachten Ritzlinie weitaus weniger gefährlich als die untere, nach wie vor ungeschützte Kante.Such a metal cover equipped with an additional edge is relatively expensive and can only protect against contact with the upper edge of the break line. However, it is precisely this upper edge that is much less dangerous than the lower, still unprotected edge due to the scratch line on the top of the lid.

Bei einer weiteren in der Praxis bekanntgewordenen Lösung ist auf der Außenseite des Metalldeckels zwischen dessen Rand und der Aufreißlinie ein Kunststoffstreifen angebracht.In another solution that has become known in practice, a plastic strip is attached to the outside of the metal cover between its edge and the tear line.

Auch damit kann jedoch die Verletzungsgefahr nicht wesentlich herabgesetzt werden, da insbesondere die innere schärfere Kante der Aufreißlinie nach wie vor freiliegt.Even with this, however, the risk of injury cannot be significantly reduced, since in particular the inner, sharper edge of the tear line is still exposed.

Bei Blechdosen ist es auch bekannt, unterhalb des Deckels einen nach innen abstehenden Wulst in den Behältermantel einzuformen, wodurch ein ungewollter Kontakt mit der Sollbruchlinie weitgehend verhindert wird.In the case of tin cans, it is also known to form an inwardly projecting bead into the container jacket below the lid, as a result of which undesired contact with the predetermined breaking line is largely prevented.

Ein derartiger Wulst wäre aber in einem aus Karton gewickelten Behälter nur äußerst schwierig herzustellen. Darüber hinaus hätte dann ein solcher Behälter keinerlei Stauchdruckfestigkeit mehr, so daß er völlig unbrauchbar wäre.Such a bead would be extremely difficult to manufacture in a container wrapped in cardboard. In addition, such a container would then no longer have any compressive strength, so that it would be completely unusable.

Durch das erfindungsgemäße Verfahren wird dagegen ein Behälter geschaffen, bei dem keine Verletzungsgefahr durch die beim Öffnen stehenbleibende Kante vorliegt.By contrast, the method according to the invention creates a container in which there is no risk of injury from the edge which remains when opening.

Die radial nach innen abstehende Bördelung verhindert wirksam eine ungewollte Berührung mit der Aufreißkante des stehen bleibenden Randes des Deckels.The radially inward flaring effectively prevents unwanted contact with the tear edge of the remaining edge of the lid.

Eine solche Bördelung bringt aber auch noch eine erhebliche Versteifung des oberen Behälterrandes mit sich.However, such flanging also entails considerable stiffening of the upper edge of the container.

Eine vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahrens liegt auch darin, daß die senkrecht nach oben stehende Bördelung in horizontaler Richtung flachgepreßt wird.An advantageous embodiment of the method according to the invention also lies in the fact that the flare standing vertically upwards is pressed flat in the horizontal direction.

Auch die nach innen abstehende Bördelung kann erfindungsgemäß in vertikaler Richtung flachgepreßt werden.According to the invention, the flanging projecting inwards can also be pressed flat in the vertical direction.

Durch diese Verpressungen kann die Stabilität des Behälters noch weiter verbessert werden. Darüber hinaus kann auch das Anbringen des Deckels erleichtert werden.The stability of the container can be further improved by these pressings. In addition, the attachment of the lid can also be facilitated.

Eine erfindungsgemäße Vorrichtung zum Durchführen des Verfahrens ist dadurch gekennzeichnet, daß ein Drehteller mit mehreren Aufnahmedornen vorgesehen ist, die jeweils einer Bearbeitungsstation zugeordnet sind, von denen die erste zum Wickeln des Behältermantels aus einem flachliegenden Kartonzuschnitt od. dgl. ausgestattet ist, während die zweite Station mit einer Siegeleinrichtung, vorzugsweise Ultraschall-Siegeleinrichtung, zum Herstellen der Behälterlängsnaht ausgerüstet ist, und daß in wenigstens einer weiteren Station eine Einrichtung zum Bördeln einer Mundrolle vorgesehen ist, während in einer anschließenden Station eine Preßeinrichtung angeordnet ist, welche die Mundrolle zu einer Doppelbördelung umformt und dabei gleichzeitig wenigstens teilweise flachpreßt, und daß weiterhin eine Deckelaufsetzeinrichtung vorgesehen ist, welche mit einem Deckel-Magazin versehen ist und in der der Deckel mit der senkrecht nach oben stehenden Bördelung der Doppelbördelung verpreßt wird.A device according to the invention for carrying out the method is characterized in that a turntable is provided with a plurality of holding mandrels, each of which is assigned to a processing station, the first of which is equipped for winding the container jacket from a flat cardboard blank or the like, while the second station is equipped with a sealing device, preferably an ultrasonic sealing device, for producing the longitudinal seam of the container, and that in at least one further station a device for flanging a mouth roll is provided, while in a subsequent station a pressing device is arranged which converts the mouth roll into a double flanging and at the same time at least partially presses flat, and that a cover fitting device is furthermore provided, which is provided with a cover magazine and in which the cover is pressed with the upward flaring of the double flanging.

Mit einer derartigen Vorrichtung kann auf einfache und äußerst rationelle Weise das Verfahren zum Herstellen des genannten Behälters durchgeführt werden.With such a device, the method for producing the aforementioned container can be carried out in a simple and extremely efficient manner.
