Description

Die Erfindung betrifft einen Dosendeckel, insbesondere für Getränkedosen, mit einem im metallischen Deckelmaterial einer Deckelfläche vorgesehenen begrenzten Öffnungsbereich, sowie einem zum Öffnen dieses Öffnungsbereichs bestimmten zweiarmigen Hebelorgan, das mit dem Deckelmaterial fest, insbesondere über eine Vernietung oder Verschweißung verbunden ist.The invention relates to a can lid, in particular for beverage cans, with a limited opening area provided in the metallic lid material of a lid surface, and with a two-armed lever element intended for opening this opening area, which is firmly connected to the lid material, in particular by riveting or welding.

Dosendeckel dieser Art werden weltweit in äußerst großem Umfang verwendet. Sie sind einfach und kostengünstig herstellbar und ermöglichen eine raumsparende Stapelung von Dosen sowie ein Öffnen der Dosen durch einfaches Hochschwenken des langen Arms des Hebelorgans. Diese allgemein bekannten Dosendeckel weisen jedoch einige gravierende Nachteile auf, die vor allem darin bestehen, dass das zunächst flach auf der Deckelfläche liegende Hebelteil nicht einfach zu ergreifen ist, dass beim Hochschwenken des Hebelorgans und dem dabei erfolgenden Öffnen der Dose der den Öffnungsbereich zunächst verschließende Deckelteilbereich in das Doseninnere gedrückt wird und dort mit der Flüssigkeit in Berührung kommt, was hygienisch nicht einwandfrei ist, und dass beim Öffnungsvorgang, d.h. dann, wenn die vorhandene Schwächungsnut zwischen dem Öffnungsbereich und der Deckelfläche aufgerissen bzw. durchtrennt wird, unvermeidbar winzige Aluminiumteilchen aus dem Deckelmaterial frei werden und auch direkt oder über den in das Doseninnere gedrückten Deckelteilbereich in die Dose gelangen. Diese winzigen Späne bzw. Aluminiumpartikel sind in gesundheitlicher Hinsicht bedenklich, wenn sie zusammen mit dem Getränk in den menschlichen Körper gelangen.Can lids of this type are used on a very large scale worldwide. They are simple and inexpensive to manufacture and enable space-saving stacking of cans and opening of the cans by simply swinging up the long arm of the lever element. However, these generally known can lids have some serious disadvantages, which mainly consist in the fact that the lever part, which initially lies flat on the lid surface, is not easy to grasp, that when the lever member is swung up and the can is opened, the part of the lid that initially closes the opening area is pressed into the inside of the can and there comes into contact with the liquid, which is not hygienically perfect, and that during the opening process, ie when the existing weakening groove between the opening area and the lid surface is torn or severed, tiny aluminum particles are inevitably released from the lid material and also enter the can directly or via the lid portion pressed into the interior of the can. These tiny chips or aluminum particles are harmful to health if they get into the human body together with the drink.

WO 2015/104659 offenbart einen Dosendeckel nach dem Oberbegriff des Anspruchs 1. WO 2015/104659 discloses a can lid according to the preamble of claim 1.

Aufgabe der vorliegenden Erfindung ist es, einen Dosendeckel der eingangs genannten Art ohne zumindest einem der vorstehend genannten Nachteile zu schaffen, d.h. insbesondere einen Dosendeckel, der sich im Vergleich zu den herkömmlichen Dosendeckeln mit wesentlich geringerem Kraftaufwand und in der Handhabung einfacher öffnen lässt, hygienisch einwandfrei ist und vor allem das Auftreten von Aluminiumspänen bzw. Aluminium-Mikropartikelchen beim Öffnungsvorgang ausschließt. Ansonsten soll eine mit dem erfindungsgemäßen Deckel versehene Dose hinsichtlich der Aufbewahrung des jeweiligen Inhalts, der Fertigungs-, Transport- und Handlingeigenschaften den herkömmlichen Dosen entsprechen.The object of the present invention is to create a can lid of the type mentioned at the outset without at least one of the disadvantages mentioned above, i.e. in particular a can lid, which is easier to open and easier to use than conventional can lids, is hygienically flawless and, above all, prevents the appearance of aluminum chips or aluminum microparticles during the opening process. Otherwise, a can provided with the lid according to the invention should correspond to the conventional cans with regard to the storage of the respective content, the manufacturing, transport and handling properties.

Gelöst wird diese Aufgabe nach einer ersten Ausführungsform der Erfindung im Wesentlichen dadurch, dass der Öffnungsbereich als Zungenlasche ausgebildet ist, die von der Deckelfläche durch einen sich über den Laschenumfang erstreckenden Mikrospalt, insbesondere einen Stanzspalt, getrennt ist und die mit der Deckelfläche verbundene Zungenlaschenbasis ein beim Öffnungsvorgang wirksam werdendes Knicklager bildet, und dass die Beschichtung dem Mikrospalt zwischen Zungenlasche und Deckelfläche benachbart geschwächt ausgeführt, insbesondere eingekerbt und vorzugsweise wenigstens teilweise durchgekerbt ist. Von besonderer Bedeutung ist bei dieser Ausführungsform der Erfindung das Zusammenwirken zwischen dem vorgesehenen Mikrospalt und der an der Deckelunterseite vorgesehenen Kunststofffolie, die dem Mikrospalt zwischen Zungenlasche und Deckelfläche benachbart so geschwächt bzw. eingekerbt ist, dass einerseits das Öffnen der Dose über den zweiarmigen Hebel mit überraschend geringer Kraft möglich und andererseits trotzdem die Anforderungen an die Dichtheit der Dose sicher gewährleistet ist. Der Mikrospalt wird dabei vorzugsweise durch einen Stanzvorgang mit anschließender Rückführung der durch das Stanzen aus dem Dosendeckelmaterial gedrückten Zungenlasche in ihre Ausgangsposition vor dem Stanzen erhalten. Das leichte, d.h. mit geringer Kraft mögliche Öffnen der Dose ist eine Folge davon, dass kein Durchtrennen von Metall nötig ist und die unterseitige Folie aufgrund der Kerbung während des Öffnens nur in einem sehr schmalen Bereich abgeschält wird.According to a first embodiment of the invention, this object is essentially achieved in that the opening area is designed as a tongue tab, which is separated from the lid surface by a micro-gap extending over the tab circumference, in particular a punching gap, and the tongue tab base connected to the lid surface The opening process becomes effective as an articulated bearing, and that the coating is weakened adjacent to the microgap between the tongue tab and the lid surface, in particular notched and preferably at least partially notched. Of particular importance in this embodiment of the invention is the interaction between the micro gap provided and the plastic film provided on the underside of the lid, which is so weakened or notched adjacent to the micro gap between the tongue tab and the lid surface that on the one hand the opening of the can via the two-armed lever is surprising low force possible and on the other hand the requirements for the tightness of the can is still guaranteed. The microgap is preferably made by a punching process with subsequent return of the tongue flap pressed out of the can lid material by punching into its starting position before Get punching. The easy opening of the can, ie possible with little force, is a consequence of the fact that it is not necessary to cut through metal and the film on the underside is only peeled off in a very narrow area due to the notch during opening.

Nach einer Ausgestaltung des vorstehenden Grundprinzips des Zusammenwirkens von Mikrospalt und an der Deckelunterseite vorgesehenen Kunststoffbeschichtung ist das zweiarmige Hebelorgan an der Deckelfläche befestigt und der kurze Hebelarm verschwenkt die Zungenlasche beim Öffnungsvorgang zusammen mit dem sie unterseitig bedeckenden, durch die Schwächungslinie begrenzten Teilbereich der Kunststoffbeschichtung in das Doseninnere, wobei dies dadurch ermöglicht wird, dass die Kerbungslinie außerhalb des Mikrospalts gelegen ist.According to one embodiment of the above basic principle of the interaction of the micro-gap and the plastic coating provided on the underside of the lid, the two-armed lever member is attached to the lid surface and the short lever arm pivots the tongue tab during the opening process together with the partial area of the plastic coating covering it on the underside and delimited by the line of weakness into the interior of the can , this being made possible by the fact that the notch line is located outside the microgap.

Damit wird jegliche störende Spanbildung beim Öffnungsvorgang ausgeschlossen und ein mit geringer Kraft mögliches Öffnen der Dose sichergestellt.This prevents any disruptive chip formation during the opening process and ensures that the can can be opened with little force.

Eine bevorzugte Weiterbildung des erfindungsgemäßen Grundprinzips besteht darin, dass das zweiarmige Hebelorgan an der Zungenlasche befestigt und mit seinem kurzen Hebelarm auf der Deckelfläche, insbesondere auf einem Versteifungsbereich der Deckelfläche abstützbar ist, und dass der lange Hebelarm die Zungenlasche beim Öffnungsvorgang zusammen mit dem sie unterseitig bedeckenden, durch die innerhalb des Mikrospalts angeordnete Schwächungslinie begrenzten Teilbereich der Kunststoffbeschichtung nach außen verschwenkt.A preferred development of the basic principle according to the invention is that the two-armed lever member is attached to the tongue tab and can be supported with its short lever arm on the lid surface, in particular on a stiffening area of the lid surface, and that the long lever arm during the opening process together with the one that covers it on the underside , pivoted to the outside by the partial area of the plastic coating which is delimited within the microgap.

Diese Ausführungsform vereint alle erreichbaren Vorteile der Erfindung in sich, da im Vergleich zu den herkömmlichen Dosendeckeln der Öffnungsvorgang einen wesentlich geringeren Kraftaufwand erfordert, das Auftreten von Aluminiumspänen bzw. Aluminium-Mikropartikelchen beim Öffnungsvorgang völlig vermieden wird und außerdem in hygienischer Hinsicht ein Optimum erzielt wird, da ein Eintauchen von Dosendeckelteilen ein in den Doseninnenraum und damit in die sich in der Dose befindende Flüssigkeit verhindert wird.This embodiment combines all of the achievable advantages of the invention since, compared to the conventional can lids, the opening process requires a significantly lower effort, the occurrence of aluminum chips or aluminum microparticles during the opening process is completely avoided and, moreover, an optimum is achieved in terms of hygiene. there an immersion of can lid parts into the can interior and thus into the liquid in the can is prevented.

Eine für alle Ausführungsvarianten vorteilhafte Ausgestaltung der Erfindung zeichnet sich dadurch aus, dass die Zungenlasche des metallischen Dosendeckels von der ihn umgebenden Deckelfläche unter Ausbildung ineinandergreifender Vorsprünge und Ausnehmungen durch einen Schneid-, insbesondere einen Stanzvorgang getrennt ist, und dass die Zungenlasche und die an diese angrenzende Deckelfläche über die Vorsprünge und Ausnehmungen form- und kraftschlüssig unter Ausbildung des Mikrospalts verbunden sind, wobei die Dichtheit des fertigen, ungeöffneten Dosendeckels durch die innenliegende Kunststoffbeschichtung bzw. Folie gewährleistet ist. Verbessert wird das Dichtvermögen gegenüber Doseninnendruck noch durch eine konkave Ausbildung der Zungenlasche.An advantageous embodiment of the invention for all design variants is characterized in that the tongue tab of the metallic can lid is separated from the lid surface surrounding it with the formation of interlocking projections and recesses by a cutting, in particular a punching process, and that the tongue tab and the one adjacent to it Cover surface on the projections and recesses are positively and non-positively connected to form the micro-gap, the tightness of the finished, unopened can lid is ensured by the internal plastic coating or film. The sealing ability against can internal pressure is improved by a concave tongue tab.

Die Vorsprünge und die Ausnehmungen sind bevorzugt über Hinterschneidungen gekoppelt.The projections and the recesses are preferably coupled via undercuts.

Insbesondere bei der Ausführungsvariante, bei der die Zungenlasche beim Öffnungsvorgang nach außen bewegt wird, ist der längere Arm des zweiarmigen Hebelorgans von einer Grifflasche, insbesondere einer Ringlasche gebildet und das zweiarmige Hebelorgan mit der Zungenlasche außermittig, insbesondere randseitig verbunden.In particular in the embodiment variant in which the tongue tab is moved outwards during the opening process, the longer arm of the two-armed lever member is formed by a grip tab, in particular an annular tab, and the two-armed lever member is connected to the tongue tab off-center, in particular at the edge.

Die Erfindung umfasst neben den im Einzelnen beschriebenen Dosendeckeln auch alle Dosen, die mit einem erfindungsgemäßen Dosendeckel versehen sind, welcher bevorzugt mit der jeweiligen Dose über einen jeweiligen Bördelrand verbunden ist, wobei insbesondere die deckelunterseitig vorgesehene Kunststofffolie im Verbindungsbereich zwischen Dosendeckel und Dose Dichtfunktion übernimmt und die gezielt positionierte Kerbung das Öffnen mit geringer Kraft ermöglicht.In addition to the can lids described in detail, the invention also includes all the cans which are provided with a can lid according to the invention, which is preferably connected to the respective can via a respective flanged edge, the plastic film provided on the underside of the lid in particular performing the sealing function in the connection area between the can lid and the can and which purposefully positioned notch allows opening with little force.

Mit dem Öffnungsbereich 4 bzw. der Zungenlasche des Dosendeckels ist ein zweiarmiger Hebel 5, 6 verbunden, insbesondere vernietet oder verschweißt, so dass sich eine feste Verbindungsstelle 7 ergibt. Diese Verbindungsstelle 7 liegt im Randbereich des Öffnungsbereichs 4, d.h. gegenüber der mit der Deckelfläche (3) verbundenen Zungenbasis, und der zweiarmige Hebel besteht aus einem kürzeren und einem längeren Bereich, wobei der längere Hebel bevorzugt von einer gut ergreifbaren Ringlasche 5 und der kürzere Bereich von einem Abstützschenkel 6 gebildet wird, der beim Hochschwenken des längeren Hebels sich auf einem Teil des Versteifungsbereichs 14 des Dosendeckels abstützt. Der zweiarmige Hebel 5, 6 liegt im Ausgangszustand im Wesentlichen parallel zur Deckelfläche 3.A two-armed lever 5, 6 is connected to the opening area 4 or the tongue tab of the can lid, in particular riveted or welded, so that there is a fixed connection point 7. This connection point 7 lies in the edge region of the opening region 4, ie opposite the tongue base connected to the cover surface (3), and the two-armed lever consists of a shorter and a longer region, the longer lever preferably being of a good quality tangible ring tab 5 and the shorter area is formed by a support leg 6, which is supported on a part of the stiffening area 14 of the can lid when the longer lever is pivoted up. In the initial state, the two-armed lever 5, 6 lies essentially parallel to the cover surface 3.

Die den Öffnungsbereich 4 bildende Zungenlasche ist form- und kraftschlüssig über Vorsprünge 12 und Ausnehmungen 13 und bevorzugt über geeignete Hinterschneidungen dieser Teile mit der Deckelfläche 3 verbunden, und zwar mit Ausnahme des Bereichs der Zungenbasis 7, wo Öffnungsbereich 4 und Deckelfläche 3 metallisch verbunden sind, so dass praktisch über eine Art Knickgelenk 9 beim Öffnen der Dose ein Hochschwenken der Zungenlasche 3 mittels des Hebels ermöglicht wird und dann Zungenlasche und Hebel außerhalb des Doseninnenraums unter Freigabe der Öffnung in eine Ruhestellung gelangen können.The tongue tab forming the opening area 4 is positively and non-positively connected to the cover surface 3 via projections 12 and recesses 13 and preferably via suitable undercuts of these parts, with the exception of the area of the tongue base 7, where the opening area 4 and cover surface 3 are metallically connected, so that practically a kind of articulated joint 9 allows the tongue tab 3 to be swiveled up by means of the lever when the can is opened, and then the tongue tab and lever can move into a rest position outside the can interior with the opening being opened.

Die geforderte Dichtheit des Dosendeckels wird trotz der fehlenden durchgehenden metallischen Verbindung zwischen Deckelfläche 3 und Öffnungsbereich 4 im Bereich der Verzahnung durch ein an der Unterseite des metallischen Deckels insbesondere vollflächig angebrachtes Kunststoffmaterial, insbesondere eine geeignete Kunststofffolie, gewährleistet, die fest haftend an der Deckelunterseite angebracht bzw. aufgesiegelt ist. Diese Beschichtung besitzt unmittelbar benachbart und innerhalb der Öffnungslinie bzw. des Mikrospalts eine ausgeprägte Schwächung 14, insbesondere eine Ein- oder teilweise Durchkerbung, so dass beim Öffnen des Dosendeckels und dem Hochziehen der Zungenlasche 4 der schmale,3 den Mikrospalt überdeckende Bereich der Kunststofffolie praktisch vom Metall abgeschält und somit ein mit geringem Kraftaufwand erfolgendes Öffnen der Dose ermöglicht wird.The required tightness of the can lid is ensured in spite of the lack of a continuous metallic connection between the lid surface 3 and the opening area 4 in the region of the teeth by a plastic material, in particular a full-surface area attached to the underside of the metallic lid, in particular a suitable plastic film, which is attached or adhered to the underside of the lid is sealed. This coating has a pronounced weakening 14, in particular a single or partial notch, directly adjacent and within the opening line or the micro-gap, so that when the can lid is opened and the tongue flap 4 is pulled up, the narrow area of the plastic film 3 covering the micro-gap practically extends from Metal peeled off and thus the can can be opened with little effort.

Um diese beim Öffnen des Dosendeckels jegliche Metallspanbildung ausschließende Gestaltung zu erreichen, wird bei der Fertigung des Dosendeckels der Öffnungsbereich bzw. die Zungenlasche durch einen Schneid- oder vorzugsweise einen Stanzvorgang die Zungenlasche von der umgebenden Deckelfläche getrennt, wobei die dabei entstehenden Späne oder Mikropartikelchen im Rahmen des Fertigungsvorgangs vollständig und problemlos beseitigt werden können. Die Zungenlasche, die über ihre Basis noch mit der Deckelfläche 3 verbunden ist, wird unmittelbar nach ihrer Ausstanzung zurück in die Deckelflächenebene gedrückt, so dass sich für die Deckelfläche praktisch wieder das ursprüngliche Erscheinungsbild ergibt, jedoch nunmehr mit einem durch den Stanzvorgang erzeugten Mikrospalt.In order to achieve this design, which excludes any metal chip formation when the can lid is opened, the opening area or the tongue tab is made by a cutting or preferably during manufacture of the can lid a punching process separates the tongue flap from the surrounding lid surface, the chips or microparticles that are produced in the process being able to be removed completely and without problems during the manufacturing process. The tongue tab, which is still connected to the cover surface 3 via its base, is pressed back into the cover surface plane immediately after it has been punched out, so that the cover surface practically returns to its original appearance, but now with a micro-gap produced by the stamping process.

Anstelle eines linienförmigen Mikrospalts werden beim Stanzvorgang bevorzugt ineinandergreifende Vorsprünge 12 und Ausnehmungen 13 erzeugt, wie dies der Fig. 1 zu entnehmen ist.Instead of a linear micro-gap, interlocking projections 12 and recesses 13 are preferably produced during the punching process, as is the case with the Fig. 1 can be seen.

In diesem Fall werden unmittelbar nach dem Stanzvorgang die beiden zunächst zum Teil getrennten Komponenten wieder formschlüssig ineinandergefügt, so dass der Dosendeckel in weiteren Fertigungsschritten in gleicher Weise gehandhabt werden kann wie herkömmliche Dosendeckel, die lediglich eine Schwächungsnut aufweisen.In this case, immediately after the punching process, the two components, some of which are initially separated, are interlocked so that the can lid can be handled in the same way in further manufacturing steps as conventional can lids, which only have a weakening groove.

Die Vorgänge des Trennens und des Ineinanderfügens erfolgen direkt nacheinander, d.h. auf den Stanzhub erfolgt im Rückhub das formschlüssige Zusammenführen beider Teile zu einem Gesamtteil. Die form- und kraftschlüssige Verbindung zwischen den beiden Bereichen wird durch geeignete Formgebung bzw. durch Verwendung von Hinterschneidungen erreicht, die eine ausreichende gegenseitige mechanische Verbindung gewährleistet, so dass dann auch die notwendigen Beschichtungsvorgänge bzw. der Vorgang des unterseitigen Aufbringens der Folie wie bei einem einheitlichen Teil durchgeführt werden können.The processes of separation and merging take place one after the other, i.e. on the punching stroke, the positive joining of the two parts into an overall part takes place in the return stroke. The positive and non-positive connection between the two areas is achieved by suitable shaping or by using undercuts, which ensure a sufficient mutual mechanical connection, so that the necessary coating processes or the process of applying the film on the underside, as with a uniform one Part can be done.

Anstelle der in der Zeichnung gezeigten Verzahnung können erfindungsgemäß auch andere, gegebenenfalls einfachere Spaltlinienverläufe beim Stanzvorgang vorgesehen werden, wobei aber in jedem Falle der Öffnungsbereich bzw. die Zungenlasche mit der Deckelfläche 3 über den Knicklagerbereich 9 verbunden bleibt und der Mikrospalt durch die innenseitig gelegene, mit einer Kerbung versehene Kunststofffolie abgedeckt ist. Die Kunststofffolie, bei der es sich um einen PP-Folie handeln kann, die beim Aufsiegeln mit dem am Metall vorgesehenen Siegellack reagiert, wird insbesondere als eigenständiges Blisterformteil hergestellt, in dem bereits die Kerbung vorgesehen ist. Wenn die Folie z.B. eine Dicke von etwa 2/10 mm beträgt, erfolgt in der Kerbung ein Schwächung auf 1/100 mm.Instead of the toothing shown in the drawing, other, possibly simpler, splitting line profiles during the punching process can also be used according to the invention are provided, but in any case the opening area or the tongue tab remains connected to the cover surface 3 via the articulated bearing area 9 and the microgap is covered by the plastic film provided with a notch on the inside. The plastic film, which can be a PP film that reacts when sealed with the sealing wax provided on the metal, is produced in particular as an independent blister molding in which the notch is already provided. For example, if the film is about 2/10 mm thick, the notch will weaken to 1/100 mm.

Die etwas vergrößerte Teildarstellung nach Fig. 3 zeigt neben der Ausgestaltung der Verbindungsstelle 7 nach Art einer Nietbindung vor allem die vollflächige Anbringung der Kunststofffolie 10 an der Unterseite des Dosendeckels und insbesondere die bevorzugt durch eine Kerbung und/oder bereichsweise Durchkerbung erreichte Ausbildung der Schwächungslinie 11 in der Kunststofffolie 10, die sich je nach Ausführungsform innerhalb oder außerhalb des Mikrospalts um den Öffnungsbereich 4 erstreckt.The somewhat enlarged partial view Fig. 3 shows, in addition to the design of the connection point 7 in the manner of a rivet bond, above all the full-surface attachment of the plastic film 10 on the underside of the can lid and in particular the formation of the weakening line 11 in the plastic film 10, which is preferably achieved by notching and / or area-wise notching, depending on the Embodiment extends inside or outside the micro-gap around the opening area 4.

Die perspektivische Darstellung nach Fig. 4 zeigt die bereits beschriebenen Gestaltungsmerkmale in besonders anschaulicher Weise und lässt auch erkennen, dass die den längeren Hebelarm bildende Ringlasche 5 aufgrund einer vorgesehenen Vertiefung in der Deckelfläche 3 bequem mit einem Finger untergriffen und zum Öffnungsvorgang nach oben geschwenkt werden kann. Bei diesem Hochschwenken der Grifflasche 5 stützt sich der kürzere Hebel 6 an dem versteiften Bereich 14 ab, wodurch im Verlauf des Hochziehens der Ringlasche der Öffnungsbereich 4 unter gleichzeitiger und jetzt ohne Spanbildung erfolgender Lösung der insbesondere formschlüssigen Kopplung von Deckelfläche 3 und Zungenlasche 4 und unter Trennung und Lösung der an der Unterseite des Deckels vorhandenen Kunststofffolie die Dose geöffnet wird.The perspective view after Fig. 4 shows the design features already described in a particularly illustrative manner and also reveals that the ring tab 5 forming the longer lever arm can be conveniently gripped with a finger due to a recess provided in the cover surface 3 and can be pivoted upwards for the opening process. During this pivoting up of the grip tab 5, the shorter lever 6 is supported on the stiffened area 14, as a result of which, in the course of pulling up the ring tab, the opening area 4, with simultaneous and now without chip formation, the particularly positive coupling of the lid surface 3 and tongue tab 4 and with separation and the solution of the plastic film on the underside of the lid is opened.

Die Ringlasche 5 und der mit ihr hochgezogene Öffnungsbereich 3 werden in den freien rechten Bereich des Dosendeckels über den in Fig. 4 unterhalb des freien Endes der Ringlasche gelegenen Knicklagerbereich 9 verschwenkt und verbleiben dort bei geöffneter Dose.The ring tab 5 and the opening area 3 pulled up with it are in the free right area of the can lid on the in Fig. 4 below the free end of the ring bracket pivoted pivot area 9 and remain there with the can open.

Wie geschildert, werden auf diese Weise sämtliche Nachteile des bisher bekannten und weit verbreiteten Dosendeckels vermieden, insbesondere vor allem die gesundheitsgefährdende Bildung von winzigen Mikro-Aluminiumpartikeln bei der Dosenöffnung. Von besonderer Bedeutung ist dabei, dass all diese Vorteile ohne wesentlichem fertigungstechnischen Mehraufwand erhalten werden.As described, all disadvantages of the previously known and widespread can lid are avoided in this way, in particular, in particular, the formation of tiny micro-aluminum particles, which is hazardous to health, when opening the can. It is particularly important here that all of these advantages are obtained without significant additional manufacturing outlay.

Das für einen Dosendeckel beschriebene Verschluss- und Öffnungssystem ist in analoger Weise auch für sonstige Gefäße und Verpackungen verwendbar, die mit einem Aufreißverschluss ausgestattet sein sollen.The closure and opening system described for a can lid can also be used in an analogous manner for other containers and packaging which are to be equipped with a zipper.
