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 eine Dose mit einem aus einem rechteckigen Kartonzuschnitt gewickelten Mantel, der wenigstens an seiner Oberseite mit einem nach innen ragenden Bördelrand versehen ist, gegen den sich von innen her eine ebene Deckelscheibe abstützt, die zum Zwecke des Öffnens mit einer Griffstelle versehen ist.The invention relates to a can with a jacket wound from a rectangular cardboard blank, which is provided at least on its top with an inwardly projecting flanged edge, against which a flat cover disk is supported from the inside, which is provided with a handle for the purpose of opening is.

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.

In der DE-U-7 739 530 wurde daher auch eine Dose der eingangs genannten Art vorgeschlagen, die an ihrer Oberseite mit einem nach innen ragenden Bördelrand versehen ist, gegen den sich eine ebene Deckelscheibe abstützt. Diese Dose ist aber nur sehr schwierig zu öffnen und so gut wie garnicht wieder zu verschliessen.DE-U-7 739 530 therefore also proposed a can of the type mentioned at the beginning, which is provided on its upper side with an inwardly projecting flanged edge against which a flat cover plate is supported. However, this box is very difficult to open and almost not to be closed again.

Aus der US-A-3 485 436 ist darüber hinaus eine Dose bekannt, die einen aus Kunststoff extrudierten Körper mit einer an dessen oberem Rand angeordneten Umfangsnut aufweist. In diese Umfangsnut greift ein kompliziert ausgebildeter Dekkel ein, der zum Öffnen der Dose aufgerissen werden kann.From US-A-3 485 436 a can is also known which has a body extruded from plastic with a circumferential groove arranged on its upper edge. A complicated lid that engages in this circumferential groove can be torn open to open the can.

Ausgehend von DE-U-7 739 530 liegt der Erfindung die Aufgabe zugrunde, eine Dose zu schaffen, die einfach ausgebaut, verhältnismässig leicht zu öffnen und wieder zu verschliessen ist.Based on DE-U-7 739 530, the invention has for its object to provide a box that is simple to remove, relatively easy to open and close again.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Griffstelle als Grifflasche ausgebildet ist, die als Ansatz an die ebene Deckelscheibe angeformt und gegen das Zentrum der Deckelscheibe hin umgefaltet ist, mit diesem umgefalteten Abschnitt auf der Oberseite der Deckelscheibe aufliegt und damit unter dem Börderrand eingeklemmt ist, und dass sich die Grifflasche entlang von zwei Schwächungslinien derart in das Innere der Deckelscheibe hinein erstreckt, dass sich beim Hochziehen der Grifflasche diese entlang der Schwächungslinien bis ins Innere der Deckelscheibe hinein von dieser abtrennt und sich dabei der Aussenumfang der Deckelscheibe bis auf den Innenumfang des Bördelrandes der Dekkelscheibe verringert und unter dem Bördelrand herausrutscht.This object is achieved according to the invention in that the grip point is designed as a grip tab, which is formed as an attachment to the flat cover plate and folded over towards the center of the cover plate, rests with this folded-over section on the top side of the cover plate and is therefore clamped under the conveyor edge , and that the grip tab extends along two lines of weakness into the inside of the cover plate such that when the grip tab is pulled up, it separates along the lines of weakness into the inside of the cover plate and the outer circumference of the cover plate extends to the inner circumference of the cover plate The flanged edge of the cover disc is reduced and slips out from under the flanged edge.

Hierdurch ist ein leichtes Öffnen der Dose ermöglicht, bei dem jedoch zwangsläufig ein teilweises - und vor allem sichtbares - Zerstören der Deckelscheibe erfolgt.This enables the can to be opened easily, but inevitably leads to a partial — and above all visible — destruction of the cover plate.

Da diese teilweise Zerstörung auch nach einem evtl. Wiederanbringen der Deckelscheibe sichtbar ist, weist die so ausgestaltete Dose einen Originalitätsverschluss auf.Since this partial destruction is also visible after the cover plate has possibly been reattached, the can designed in this way has a tamper-evident seal.

in der Zeichnung ist die Erfindung anhand eines Ausführungsbeispiels dargestellt. Dabei zeigenthe invention is shown in the drawing using an exemplary embodiment. Show

Fig. 1 einen Schnitt durch eine am oberen und unteren Rand eingebördelte Dose mit Bodenscheibe und Deckeischeibe undFig. 1 shows a section through a box flanged at the top and bottom with bottom plate and cover plate and

Fig. 2 eine Draufsicht auf die Deckelscheibe.Fig. 2 is a plan view of the cover plate.

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 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 cover disk 6 is supported on this filling material, against which the upper edge of the can jacket 1 is rolled up until it abuts the cover 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 Schwächungslinien 11, 12 von dieser abtrennbar 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 can be separated from it by two lines of weakness 11, 12.

Zum Öffnen der Dose wird der Ansatz 9 ergriffen und nach oben gezogen. Dadurch werden dieser und der Streifen 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 Schwächungslinien 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 strip 10 are drawn out from under the flanged edge 8. 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 lines of weakness 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 seal, since opening is only possible by partially destroying the cover plate.
