Description

Griffringlasche für Getränkedosenverschluß Handle ring flap for beverage can closure
Die Erfindung betrifft eine Griffringlasche für einen Getränkedosenverschluß mit einem einstückig einteiligen Verbindungsband der Ringlasche zur Ge¬ tränkedose.The invention relates to a grip ring tab for a beverage can closure with a one-piece, one-piece connecting band of the ring tab to the beverage can.
Die auch nach dem Öffnen mit der Dose zusammenhängen¬ de Griffringlasche erweist sich als umweltfreundlich, da auf diese Weise ein Recycling auch der Griffring¬ lasche sichergestellt wird und insbesondere dann auch von der scharfkantigen Lasche ausgehende Verletzungen vermieden werden.The handle ring tab, which is also connected to the can after opening, has proven to be environmentally friendly, since recycling of the handle ring tab is also ensured in this way and, in particular, injuries resulting from the sharp-edged tab are avoided.
Mit der Dose bleibend verbundene Griffringlaschen sind beispielsweise aus der US-PS 3 908 856 bzw. aus der DE-OS 24 54 656 zu entnehmen» Hierbei wird die Verbin¬ dung allerdings über die Lasche herge.stellt , die mit dem Dosendeckel durch ein Verbindungsglied bleibend verbunden ist, das einerseits am Gehäusedeckel und andererseits an der Lasche befestigt ist. Eine gattungs¬ gemäße Griffringlasche ist der US-PS 3 373 895 zu ent¬ nehmen. Hierbei wird die bleibende Verbindung der Griff- ringlasche durch die sich endseitig nicht von der Dose lösende Lasche selbst bewirkt, wobei die Lasσhe in be¬ sonderer Weise geprägt ist und die Dose dann auch in besonderer Weise zu öffnen ist.Grip ring tabs that are permanently connected to the box can be found, for example, in US Pat. No. 3,908,856 or DE-OS 24 54 656. In this case, however, the connection is made via the tab, which is provided with the can lid is permanently connected by a connecting member which is attached on the one hand to the housing cover and on the other hand to the tab. A generic grip ring tab can be found in US Pat. No. 3,373,895. In this case, the permanent connection of the grip ring lug is brought about by the lug itself which does not detach itself from the end of the can, the lash being shaped in a special way and the can then also being opened in a special way.
Erfindungsgemäß wird nunmehr eine Griffringlasche der eingangs umrissenen Gattung vorgeschlagen, die dadurch gekennzeichnet ist, daß das Verbindungsband aus der Blechscheibe des Ringinnenteils der Ringlasche spiral- förmig ausgestanzt ist.According to the invention, a grip ring tab of the type outlined at the outset is now proposed, which is characterized in that the connecting band is punched out in a spiral shape from the sheet metal disc of the inner ring part of the ring tab.
Hierbei bedarf es einerseits keines zusätzlichen Ver¬ bindungsgliedes, die Verbindung wird vielmehr durch das sonst in Fortfall kommende, in besonderer Weise bearbeitete Innenteil des Griffringes hergestellt, andererseits bleibt der herkömmliche einfache Öffnungs¬ vorgang allein durch Hochreißen der den Verschluß bil¬ denden Lasche unbeeinträchtigt, die dann auch den Trinkvorgang nicht beeinträchtigt.On the one hand, there is no need for an additional connecting element, the connection is rather made by the otherwise machined, specially machined inner part of the grip ring, on the other hand, the conventional simple opening process remains unaffected simply by tearing up the tab forming the closure, which then does not affect the drinking process.
Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Embodiments of the invention result from the subclaims.
In der Zeichnung ist die Erfindung anhand eines Aus¬ führungsbeispieles weitergehend erläutert. Es zeigenIn the drawing, the invention is further explained using an exemplary embodiment. Show it

Figur 4 einen Vertikalschnitt durch den Dosen¬ deckel im Bereich des auf ihm aufliegen¬ den Griffringes.FIG. 4 shows a vertical section through the can lid in the area of the grip ring resting on it.
In Figur 1 ist eine Getränkedose 11 dargestellt, die im Dosendeckel 111 mit einer durch eine Zuglasche 21 ver¬ schlossenen Öffnung 112 (Figur 2) versehen ist. An die Zuglasche 21 ist ein Griffring 22 angenietet (23), mit dem die Zuglasche 21 zum Öffnen der Dose 11 hochgerissen wir .FIG. 1 shows a beverage can 11 which is provided in the can lid 111 with an opening 112 (FIG. 2) closed by a pull tab 21. A grip ring 22 is riveted to the pull tab 21 (23), by means of which we pull up the pull tab 21 to open the can 11.
Die Griffringlasche 21 /22 ist bleibend verbunden mit der Dose 1.1 durch ein aus dem Innenteil des Griffringes 22 spiralförmig ausgestanztes Verbindungsband 221 , das vom Griffring 22 ausgehend (222) auf dem Dosendeckel 111 festgenietet ist (24), wozu das freie mit dem Dosendeckel 111 verbundene Ende des Bandes 221 als Scheibe 223 aus¬ gebildet ist.The grip ring flap 21/22 is permanently connected to the box 1.1 by a connecting band 221 stamped out of the inside of the grip ring 22 and which is riveted from the grip ring 22 (222) to the can lid 111 (24), for which purpose the free one with the can lid 111 connected end of the band 221 is formed as a disk 223.
In Figur 3 ist der Rohling des im Sinne der Erfindung ausgestalteten Griffringes 22 dargestellt, Hierbei sind mit 227 und 228 die äußere und die innere Börtelkante be-FIG. 3 shows the blank of the grip ring 22 designed in accordance with the invention. 227 and 228 denote the outer and inner edge of the wall.
OMPI zeichnet, die vor der Zuordnung des Griffringes 22 zum Dosendeckel 111 umgebörtelt werden.OMPI records, which are flanged before the assignment of the grip ring 22 to the can lid 111.
Aus dieser Figur ist dann auch deutlich erkennbar, wie aus dem Innenteil des Griffringes 21 das Ver¬ bindungsband 211 spiralförmig in der Weise ausge¬ stanzt ist, daß bei 222 eine hinreichende Material¬ verbindung zum Griffring 22 erhalten bleibt- und daß das freie Ende des Bandes 211 in eine Scheibe 223 ausläuft. Die Scheibe 223 nimmt im Bereich der Vor¬ prägung 224 den Niet 24 auf, mit dem das Verbindungs¬ band 211 und damit dann auch der Griffring 22 am Dosendeckel 111 befestigt wird. Mit 226 ist der vor¬ geprägte Durchgang im Griffring 22 für die Verbin- düng des Griffrings 22 mit der Zuglasche 21 gekenn¬ zeichnet, was vorzugsweise ebenfalls durch Nietung erfolgt (23).From this figure it can also be clearly seen how the connecting band 211 is punched out helically from the inner part of the grip ring 21 in such a way that a sufficient material connection to the grip ring 22 is maintained at 222 and that the free end of the Belt 211 runs out into a disc 223. In the area of the pre-embossing 224, the disk 223 receives the rivet 24, with which the connecting band 211 and thus also the grip ring 22 is fastened to the can lid 111. The pre-embossed passage in the grip ring 22 for the connection of the grip ring 22 to the pull tab 21 is identified by 226, which is also preferably done by riveting (23).
Mit dem Umbörteln der Innenkante 228 des Griffringes 22 geht in vorteilhafter Weise eine Verdrillung desWith the edging of the inner edge 228 of the grip ring 22, twisting of the
Verbindungsbandes 211 am Übergang vom Griffring 22 in das Band 211 einher.Connection band 211 at the transition from the grip ring 22 into the band 211.
Zweckmäßigerweise ist, wie das aus Figur 4 ersichtlich ist, im Dosendeckel 111 eine Senke 113 vorgesehen, in die sich das Innenteil (211) des Griffrings 22 bei noch verschlossener Dose 11 einfügt. 4, a depression 113 is expediently provided in the can lid 111, into which the inner part (211) of the grip ring 22 fits when the can 11 is still closed.
