Definitions
- the invention relates to a resealable closure of a liquid container, in particular a beverage can, with a lid closing the liquid container via a bead and a cover, the lid having an outlet opening which can be exposed by rotating the cover arranged on the lid.
- beverage cans have become known that have a resealable pouring.
- the DE 196 13 246 A1 an applied on the existing lid closure means having substantially the same diameter, which closes by turning a pouring opening located in the lid.
- Similar devices, with some of these closure means only partially covering the lid, are in the DE 196 13 256 B4 , of the DE 197 06 112 C2 , of the EP 1 247 752 B1 or the US 6,626,314 B1 described.
- a disadvantage of these closures is their usually complicated structure, which also usually requires undesirable structural changes of the lid of the can.
- Another group of closure means for beverage cans consists of a pull tab, which is attached for example by means of a rivet on the can lid, wherein the handle portion of the pull tab is simultaneously formed as a closure means for the pouring opening, which after opening the pouring opening by turning and / or folding the Pull-tab closes the pouring opening again.
- Such elements are inter alia in the DE 197 46 539 A1 , of the DE 203 19 105 U1 , of the EP 1 190 952 A2 , of the EP 1 097 086 B1 and the EP 0 433 502 A1 shown.
- These beverage cans all have a closure that is applied from the outside to the pouring opening and thereby partially protrudes beyond the edge of the lid, so that it can be removed unintentionally, and thus the can content is exposed to the environment.
- the GB 2 331 284 A Finally, describes a closure system consisting of a pull tab for exposing a pouring opening, and a closure means which is arranged on the underside of the can lid in the interior of the can, wherein a spring element presses the closure means against the pouring opening.
- a closure means which is arranged on the underside of the can lid in the interior of the can, wherein a spring element presses the closure means against the pouring opening.
- parts of the closure means have to be displaced against the tear-open tab.
- This closure means has the disadvantage that it is constructed extremely complicated and also requires a change of the usual can lid.
- a slightly simpler in construction, also multi-part closure device can the US 3,889,842 be removed, which also requires a lavishly changed lid.
- Similar reusable closure means are described.
- Another problem of resealable containers of the type mentioned is the tightness of the re-sealed beverage can. Especially during prolonged storage of the still unopened can cause problems with the sealing elements, if they are mechanically stressed during storage or remain in a state of stress. It is therefore an object of the invention to eliminate the disadvantages of the prior art described above and to provide a lid for a can having a secure, in particular liquid-tight closure system for reclosing the can, which are preferably mounted in a simple and cost-effective manner in commercial lids can.
- a closure according to the preamble of claim 1 in which a seal between the container lid and a rotatable on the container lid second lid is arranged.
- the disadvantage of this arrangement that at the container lid facing the underside of the second lid arranged seal is stored under tension before the first opening of the container and also mechanically stressed during rotation of the second lid, so when resealing the sealing of the exposed during opening drinking opening not sufficient anymore.
- This invention is inventively achieved in that the lid has at least one recess for receiving at least one sealant between the lid and cover.
- the at least one sealing agent in the case of an unopened beverage can, the at least one sealing agent remains relaxed in this two-dimensional depression, so that no tension forces can act on the preferably annular sealing means and thus cause premature wear thereof.
- the at least one sealing means on the cover is preferably arranged insoluble.
- the sealing means is arranged in a receptacle of the cover and remains in the recess of the lid, as long as the beverage can is closed. It is particularly preferred that in a first position of the cover relative to the lid, the at least one sealing means is arranged in the at least one recess, while the outlet opening is originally closed. In this state, the sealant is without function.
- the at least one sealing means is arranged in the region of the exposed outlet opening, while the outlet opening is closed by the cover.
- the sealing means fulfills its intended purpose, namely to seal the exposed outlet opening of the lid against the cover in order to reseal the beverage can liquid and / or gas-tight.
- the cover can be fastened to the liquid container by at least two snap-in hooks, which surround the beading edge in sections and which engage one another.
- a particularly easy attachment of the cover on the lid and thus on the beverage can is achieved when the at least two snap hooks are movably arranged on the cover.
- the snap hooks are made in one piece with the cover and are pivotally connected via a material taper with the cover.
- the lid is at least partially made of plastic.
- This lid which is preferably made of a stable plastic material, has the same properties as that of metal, but is less expensive to produce.
- At least one Aufdrücknocke is arranged at the outlet, which has at least one Aufdrückelement, which is preferably hook-shaped.
- This hook-shaped Aufdschreibelement engages the first time opening in the surrounding the outlet opening crack line and this case simultaneously causes a pressure equalization, which facilitates the further opening of the outlet opening.
- the cover can be brought by the user in exactly the intended position, whereby problems can be avoided, for example, with the tightness of the re-sealed beverage can.
- the element for determining the position of the cover with respect to the cover is designed as at least one index cam arranged on the cover, which can be latched into at least one recess of the cover.
- the cover has at least one groove or depression into which at least one elevation or cam arranged on the cover can be latched.
- the position of the cover is indicated by an acoustic signal, in particular a click.
- a resealable non-inventive closure 100 for a soda can 200 is shown in various exploded views.

Description
Die Erfindung betrifft einen wiederverschließbaren Verschluss eines Flüssigkeitsbehälters, insbesondere einer Getränkedose, mit einem den Flüssigkeitsbehälter über einen Bördelrand verschließenden Deckel und einer Abdeckung, wobei der Deckel eine Auslassöffnung aufweist, die durch Verdrehen der auf dem Deckel angeordneten Abdeckung freilegbar ist.The invention relates to a resealable closure of a liquid container, in particular a beverage can, with a lid closing the liquid container via a bead and a cover, the lid having an outlet opening which can be exposed by rotating the cover arranged on the lid.
Es sind zahlreiche Getränkedosen bekannt geworden, die über eine wiederverschließbare Ausgießöffnung verfügen. So offenbart beispielsweise die
Eine weitere Gruppe von Verschlussmittel für Getränkedosen besteht aus einer Aufreißlasche, die beispielsweise mittels einer Nietverbindung an dem Dosendeckel befestigt ist, wobei der Griffteil der Aufreißlasche gleichzeitig als Verschlussmittel für die Ausgießöffnung ausgebildet ist, das nach dem Öffnen der Ausgießöffnung durch Verdrehen und/oder Umklappen der Aufreißlasche die Ausgießöffnung wieder verschließt. Derartige Elemente sind unter anderem in der
Die
Ein weiteres Problem von wiederverschließbaren Behältnissen der eingangs erwähnten Art ist die Dichtigkeit der wiederverschlossenen Getränkedose. Insbesondere bei längerer Lagerung der noch ungeöffneten Dose kann es zu Problemen mit den Dichtelementen kommen, wenn diese während der Lagerzeit mechanisch beansprucht werden oder in einem Spannungszustand verbleiben.
Es ist daher Aufgabe der Erfindung die oben beschriebenen Nachteile des Standes der Technik zu beseitigen und einen Deckel für eine Dose bereitzustellen, der über ein sicheres, insbesondere flüssigkeitsdichtes Verschlusssystem zum Wiederverschließen der Dose verfügt, das bevorzugterweise auf einfache und kostengünstige Weise in handelsübliche Deckel montiert werden kann.Another problem of resealable containers of the type mentioned is the tightness of the re-sealed beverage can. Especially during prolonged storage of the still unopened can cause problems with the sealing elements, if they are mechanically stressed during storage or remain in a state of stress.
It is therefore an object of the invention to eliminate the disadvantages of the prior art described above and to provide a lid for a can having a secure, in particular liquid-tight closure system for reclosing the can, which are preferably mounted in a simple and cost-effective manner in commercial lids can.

Diese Erfindung wird erfindungsgemäß dadurch gelöst, dass der Deckel zumindest eine Vertiefung zur Aufnahme zumindest eines Dichtmittels zwischen Deckel und Abdeckung aufweist. Erfindungsgemäß ist vorgesehen, dass bei ungeöffneter Getränkedose das zumindest eine Dichtmittel entspannt in dieser flächigen Vertiefung verbleibt, sodass keine Spannungskräfte auf das vorzugsweise ringförmige Dichtmittel einwirken und damit einen vorzeitigen Verschleiß desselben verursachen können.
In einer bevorzugten Ausführung der Erfindung ist das zumindest eine Dichtmittel an der Abdeckung vorzugsweise unlösbar angeordnet. Hierbei ist beispielsweise vorgesehen, dass das Dichtmittel in einer Aufnahme der Abdeckung angeordnet ist und in der Vertiefung des Deckels verbleibt, solange die Getränkedose verschlossen ist.
Besonders bevorzugt ist, dass in einer ersten Stellung der Abdeckung relativ zu dem Deckel das zumindest eine Dichtmittel in der zumindest einen Vertiefung angeordnet ist, während die Auslassöffnung original verschlossen ist. In diesem Zustand ist das Dichtmittel ohne Funktion.
In einer zweiten Stellung der Abdeckung relativ zu dem Deckel ist vorgesehen, dass das zumindest eine Dichtmittel im Bereich der freigelegten Auslassöffnung angeordnet ist, während die Auslassöffnung durch die Abdeckung verschlossen ist. In dieser Position der Abdeckung erfüllt das Dichtmittel seinen vorgesehenen Zweck, nämlich die freigelegte Auslassöffnung des Deckels gegen die Abdeckung abzudichten, um die Getränkedose flüssigkeits- und/oder gasdicht wiederzuverschließen.In the
This invention is inventively achieved in that the lid has at least one recess for receiving at least one sealant between the lid and cover. According to the invention, it is provided that, in the case of an unopened beverage can, the at least one sealing agent remains relaxed in this two-dimensional depression, so that no tension forces can act on the preferably annular sealing means and thus cause premature wear thereof.
In a preferred embodiment of the invention, the at least one sealing means on the cover is preferably arranged insoluble. Here, for example, it is provided that the sealing means is arranged in a receptacle of the cover and remains in the recess of the lid, as long as the beverage can is closed.
It is particularly preferred that in a first position of the cover relative to the lid, the at least one sealing means is arranged in the at least one recess, while the outlet opening is originally closed. In this state, the sealant is without function.
In a second position of the cover relative to the cover is provided that the at least one sealing means is arranged in the region of the exposed outlet opening, while the outlet opening is closed by the cover. In this position of the cover, the sealing means fulfills its intended purpose, namely to seal the exposed outlet opening of the lid against the cover in order to reseal the beverage can liquid and / or gas-tight.
In einer weiteren Ausführung der Erfindung ist vorgesehen, dass die Abdeckung über zumindest zwei den Bördelrand abschnittsweise, voneinander getrennt umgreifende Schnapphaken an dem Flüssigkeitsbehälter befestigbar ist. Mithilfe dieser Schnapphaken, die die Abdeckung nur abschnittsweise mit dem Deckel in Eingriff bringen, kann die Abdeckung leichter relativ zum Deckel verdreht werden, weil der Reibungswiderstand verringert ist.In a further embodiment of the invention, it is provided that the cover can be fastened to the liquid container by at least two snap-in hooks, which surround the beading edge in sections and which engage one another. By means of these snap hooks, which engage the cover only partially with the lid, the cover can be rotated more easily relative to the lid, because the frictional resistance is reduced.
Ein besonders leichtes Anbringen der Abdeckung auf dem Deckel und damit auf die Getränkedose wird erzielt, wenn die zumindest zwei Schnapphaken beweglich an der Abdeckung angeordnet sind. Hierzu ist bevorzugterweise vorgesehen, dass die Schnapphaken einstückig mit der Abdeckung gefertigt sind und über eine Materialverjüngung mit der Abdeckung gelenkig in Verbindung stehen.A particularly easy attachment of the cover on the lid and thus on the beverage can is achieved when the at least two snap hooks are movably arranged on the cover. For this purpose, it is preferably provided that the snap hooks are made in one piece with the cover and are pivotally connected via a material taper with the cover.
In einer weiteren Variante der Erfindung ist vorgesehen, dass der Deckel zumindest teilweise aus Kunststoff gefertigt ist. Dieser bevorzugterweise aus stabilem Kunststoff hergestellte Deckel weist hierbei die gleichen Eigenschaften wie jener aus Metall auf, ist jedoch kostengünstiger herzustellen.In a further variant of the invention it is provided that the lid is at least partially made of plastic. This lid, which is preferably made of a stable plastic material, has the same properties as that of metal, but is less expensive to produce.
Um das erstmalige Öffnen der Getränkedose zu erleichtern, ist in einer weiteren Ausführung der Erfindung vorgesehen, dass an der Auslassöffnung zumindest eine Aufdrücknocke angeordnet ist, die über zumindest ein Aufdrückelement verfügt, das vorzugsweise hakenförmig ausgebildet ist. Dieses hakenförmige Aufdrückelement greift beim erstmaligen Öffnen in die die Auslassöffnung umgebenden Risslinie ein und bewirkt hierbei gleichzeitig einen Druckausgleich, der das weitere Öffnen der Auslassöffnung erleichtert.In order to facilitate the initial opening of the beverage can, it is provided in a further embodiment of the invention that at least one Aufdrücknocke is arranged at the outlet, which has at least one Aufdrückelement, which is preferably hook-shaped. This hook-shaped Aufdrückelement engages the first time opening in the surrounding the outlet opening crack line and this case simultaneously causes a pressure equalization, which facilitates the further opening of the outlet opening.
Besonders bevorzugt ist vorgesehen, dass zumindest ein Element zur Festlegung der Position der Abdeckung in Bezug auf den Deckel vorgesehen ist. Damit kann die Abdeckung vom Benutzer in genau die vorgesehen Position gebracht werden, wodurch Probleme beispielsweise mit der Dichtheit der wiederverschlossenen Getränkedose vermieden werden können.Particularly preferably, it is provided that at least one element is provided for determining the position of the cover with respect to the lid. Thus, the cover can be brought by the user in exactly the intended position, whereby problems can be avoided, for example, with the tightness of the re-sealed beverage can.
Vorzugsweise ist das Element zur Festlegung der Position der Abdeckung in Bezug auf den Deckel als zumindest eine auf dem Deckel angeordnete Indexnocke ausgebildet, die in zumindest eine Ausnehmung der Abdeckung einrastbar ist. Alternativ hierzu ist vorgesehen, dass der Deckel zumindest eine Nut oder Vertiefung aufweist, in die zumindest eine an der Abdeckung angeordnete Erhebung oder Nocke einrastbar ist. In einer weiteren Variante wird alternativ oder kumulativ die Position der Abdeckung durch ein akustisches Signal, insbesondere ein Klacken angezeigt.Preferably, the element for determining the position of the cover with respect to the cover is designed as at least one index cam arranged on the cover, which can be latched into at least one recess of the cover. Alternatively, it is provided the cover has at least one groove or depression into which at least one elevation or cam arranged on the cover can be latched. In a further variant, alternatively or cumulatively, the position of the cover is indicated by an acoustic signal, in particular a click.

Des weiteren weist die Abdeckung 400 eine Trinköffnung 420 auf, die bei geöffneter Trinköffnung 320 des Deckels 300 der Getränkedose 200 diese dicht umschließt, so dass beim Trinken aus der Getränkedose 200 keine Flüssigkeit zwischen Deckel 300 und Abdeckung 400 gelangen kann. Zusätzlich sind Dichteinrichtungen 430 an der dem Deckel 300 zugewandten Oberfläche der Abdeckung 400 vorgesehen, deren Aufgabe es ist, beim Wiederverschließen der Getränkedose 200 ein Auslaufen von Flüssigkeit durch die Trinköffnung 320 des Deckels 300 zu verhindern.Furthermore, the
Vorzugsweise ist die Trinköffnung 420 der Abdeckung 400 kleiner als die Trinköffnung 320 im Deckel 300 ausgeführt, um eine Belüftung der Getränkedose 200 zu ermöglichen. Da beim Trinken aus der Getränkedose 200 häufig die Trinköffnung 420 der Abdeckung zur Gänze von den Lippen der trinkenden Person umschlossen ist und dadurch ein Unterdruck in der Getränkedose 200 entstehen kann, erlaubt die größere Trinköffnung 320 eine Belüftung der Getränkedose 200, wobei die Dichtelemente 430 in der Geöffnet-Position, also beim Trinken, derart angeordnet sind, dass eine derartige Belüftung über die Trinköffnung 320 im Deckel 300 möglich ist.Preferably, the drinking opening 420 of the

An der den Deckel 300 abgewandten Oberfläche der Abdeckung 400 können beispielsweise Markierungen oder Beschriftungen vorgesehen sein, die die genaue Position der Abdeckung 400 relativ zum Deckel 300 bezeichnen, um die Öffnungs- bzw. Geschlossen-Position der Abdeckung 400 genau zu definieren (nicht dargestellt). Alternativ hierzu können auch Einrichtungen vorgesehen sein, die durch ein akustisches Signal, beispielsweise ein Klacken, das Erreichen einer bestimmten Position anzeigen.If the beverage can 200 is not completely emptied, the

Der Deckel 300 weist zudem zwei flächige Vertiefungen 360, 361 auf, die über einen aus der Deckelebene ragenden Dichtbereich 370 von einander getrennt sind. Dieser Dichtbereich 370 wirkt im zusammengesetzten Zustand mit der Abdeckung 400 derart zusammen, dass weder in der Geöffnet-Position - beispielsweise beim Trinken - noch beim Wiederverschließen der Getränkedose 200 in der Geschlossen-Position Inhalt der Getränkedose 200 zwischen Deckel 300 und Abdeckung 400 und/oder aus der verschlossenen Getränkedose 200 heraus gelangen kann. Des Weiteren bewirkt dieser eingeprägte Dichtbereich 370 eine mechanische Versteifung des Deckels 300.The
In den Vertiefungen 360, 361 ruht im Auslieferungszustand (also vor dem ersten Öffnen der Getränkedose 200) ein Dichtmittel (nicht dargestellt), vorzugsweise eine Elastomerdichtung, das in der Abdeckung 400 angeordnet ist, sodass in der üblicherweise langen Zeitperiode der Lagerung vor dem ersten Öffnen der Getränkedose 200 die Dichtung entspannt lagert. Dies hat den Vorteil, dass in dieser Position praktisch keine oder nur sehr geringe mechanische Belastungen auf das Dichtmittel wirken, sodass es zu keinen Spannungsverlusten und damit Verringerung der Dichtigkeit im Gebrauch auftreten. Als Dichtmaterialien kommen vorzugsweise elastische Kunststoffe zum Einsatz, wobei das Dichtmittel ringförmig oder aber flächig ausgebildet sein kann.In the
