Description

Die Erfindung betrifft eine Verschlußkappe gemäß dem Oberbegriff des Schutzanspruchs 1.The invention relates to a closure cap according to the preamble of patent claim 1.

Eine derartige Verschlußkappe ist aus der DE 43 38 004 C2 bekannt. Bei dieser bekannten Verschlußkappe ist der Orginalitätssprengring durch eine Verformungszone im Bereich des Schaftes gebildet, die nach oben durch eine Reihe von horizontalen Schlitzen mit dazwischen liegenden Stegen und nach unten durch eine nach außen vorspringende Sicke begrenzt wird. Zusätzlich sind im Bereich der Verformungszone vertikale Materialschwächungen vorgesehen. Beim erstmaligen Öffnen der Flasche weitet sich die Verformungszone beim Abschrauben auf den Außendurchmesser des Flaschengewindes auf, so dass die Kappe insgesamt einstückig entfernt werden kann. Die vertikalen Materialschwächungen weiten sich dabei mehr oder weniger regelmäßig auf und bilden somit einen Indikator für die Erstöffnung der Flasche. Hierbei ist die Abstimmung so getroffen, dass die für die Aufweitung erforderliche Kraft kleiner ist als die zum Abreißen der Stege zwischen den horizontalen Schlitzen erforderliche Kraft. Nachteilig bei dieser bekannten Verschlußkappe ist, dass die Einbringung der Schlitze und Stege sowie die Abstimmung der Abreißkräfte für die Stege bzw. die Aufweitungskräfte für die Materialschwächungen einen erhöhten Aufwand erfordert. Außerdem können, wie in DE 43 38 004 C2 beschrieben, beim erstmaligen Öffnen der Flasche die vertikalen Materialschwächungen bis in den Bereich der horizontalen Schlitze aufreißen. Damit entstehen scharfkantige Sektionen in diesem Bereich des Verschlusses, die wiederum zu Verletzungen der Finger des Benutzers führen können. Zudem ist es nachteilig, dass sich der Verschluß beim Wiederverschließen mit einfachen Mittel manipulieren läßt, indem beispielsweise mit einem runden Gegenstand, wie einem Nagel, nach dem Aufschrauben der Verschlußkappe im Bereich des Orginalitätssprengrings die ursprüngliche Einrollung durch Andrücken dieses Gegenstandes wieder erzeugt werden kann. Der Verbraucher kann dann nicht mehr eindeutig erkennen, ob bereits vorher eine Erstöffnung erfolgte. Einem Austausch, einer Vermischung oder schlimmstenfalls sogar einer Vergiftung des Flascheninhaltes ist damit Tor und Tür geöffnet.Such a closure cap is known from DE 43 38 004 C2. In this known cap the Orginalitätssprengring is formed by a deformation zone in the region of the shaft, which is bounded above by a series of horizontal slots with intermediate webs and down by an outwardly projecting bead. In addition, vertical material weakenings are provided in the region of the deformation zone. When opening the bottle for the first time, the deformation zone widens when unscrewing on the outer diameter of the bottle thread, so that the cap can be removed in one piece as a whole. The vertical weakenings widen more or less regularly and thus form an indicator for the first opening of the bottle. Here, the vote is such that the force required for the expansion force is smaller than the force required for tearing off the webs between the horizontal slots. A disadvantage of this known closure cap that the introduction of the slots and webs and the vote of the Abreißkräfte for the webs and the expansion forces for the material weakening requires increased effort. In addition, as described in DE 43 38 004 C2, when opening the bottle for the first time, the vertical weakening of the material can tear into the region of the horizontal slots. This creates sharp-edged sections in this area of the closure, which in turn can lead to injuries of the user's fingers. In addition, it is disadvantageous that the closure can be manipulated with simple means when re-closing, for example, with a round object, such as a nail, after screwing the cap in the region of the Orginalitätssprengrings the original curl by pressing this object again can be generated. The consumer can then no longer clearly recognize whether a first opening was already made. An exchange, mixing or even poisoning of the contents of the bottle opens the door and the door.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Verschlußkappe zu schaffen, die ein einteiliges Abschrauben in Verbindung mit einem dichten Wiederverschließen und einer eindeutigen Orginalitäts-Sicherung ermöglicht.The present invention has for its object to provide a cap that allows a one-piece unscrewing in conjunction with a tight reclosing and a unique Orginalitäts-fuse.

Diese Aufgabe wird durch die in Patentanspruch 1 angegebenen Mittel gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.This object is achieved by the means specified in claim 1. Advantageous embodiments of the invention can be found in the dependent claims.

Die Erfindung sieht vor, dass das Originalitätssicherungselement von wenigstens einer Materialschwächung im Bereich der Verformungszone gebildet wird, die ausgehend von einer unteren ungeschwächten Basislinie eine nach oben weisende geschlossene Kontur bildet. Der von dieser Kontur umschlossene Materialbereich wird beim erstmaligen Abdrehen der Verschlußkappe vom Flaschenmundstück beim Aufweiten der Verformungszone aus dieser teilweise herausgetrennt und nach innen geklappt, so dass im Material bleibende, irreparable Fehlstellen entstehen, die dem Benutzer eindeutig anzeigen, ob die Flasche original verschlossen ist oder ob diese bereits geöffnet war. Dadurch, dass die Bereiche innerhalb der Konturen nach innen bewegt werden, entsteht auch keinerlei Verletzungsgefahr für den Benutzer der Verschlußkappe.The invention provides that the tamper-evident element is formed by at least one material weakening in the region of the deformation zone which, starting from a lower unattenuated baseline, forms an upwardly directed closed contour. The material area enclosed by this contour is partially removed during initial widening of the cap from the bottle mouthpiece during expansion of the deformation zone and folded inwards, so that the material permanent, irreparable flaws arise that clearly indicate to the user whether the bottle is originally sealed or if it was already open. The fact that the areas within the contours are moved inward, there is no risk of injury to the user of the cap.

Besonders vorteilhaft ist die Erfindung an einer Verschlußkappe einsetzbar, bei der sich an die Verformungszone nach unten ein weiterer Schaftbereich anschließt. Derartige Verschlußkappen sind der Fachwelt auch unter den Begriffen Stelcap oder auch Longcap bekannt.The invention can be used particularly advantageously on a closure cap in which a further shaft region adjoins the deformation zone downwards. Such caps are known in the art under the terms Stelcap or Longcap.

Bevorzugt wird die Verformungszone von einer oberen Sicke und einer unteren Sicke begrenzt. Derartige Sicken sorgen für eine eindeutige Begrenzung der Verformungszone und verleihen dem Verschluß mehr Stabilität im Schaftbereich.Preferably, the deformation zone is limited by an upper bead and a lower bead. Such beads provide a clear boundary of the deformation zone and give the closure more stability in the shaft area.

Besonders bevorzugt ist eine Ausführungsform, bei der sich die Kontur der Materialschwächung im unteren Bereich der Verformungszone erstreckt. Dabei befindet sich der oberste Punkt der Kontur der Materialschwächung etwa in der Mitte der Verformungszone, bevorzugt etwas unterhalb der Mitte der Verformungszone. Durch diese Maßnahme wird erreicht, dass sich das Material im Bereich der Kontur der Verformungszone bei der Erstöffnung eindeutig nach innen in den Innenbereich der Verschlußkappe bewegt, so dass keine Vorsprünge nach außen gebildet werden, die eine Verletzungsgefahr für die Finger des Benutzers darstellen könnten.Particularly preferred is an embodiment in which the contour of the material weakening extends in the lower region of the deformation zone. In this case, the uppermost point of the contour of the material weakening is located approximately in the middle of the deformation zone, preferably slightly below the middle of the deformation zone. This measure ensures that the material in the region of the contour of the deformation zone at the first opening moves clearly inwards into the inner region of the closure cap, so that no projections are formed outwardly, which could pose a risk of injury to the user's fingers.

Bevorzugt sind in der Verformungszone am Umfang verteilt mehrere weitere im wesentlichen vertikal verlaufende Materialschwächungen vorgesehen, wie diese an sich aus dem eingangs zitierten Stand der Technik bekannt sind. Diese Materialschwächungen erleichtern das Aufweiten der Verformungszone bei der Erstöffnung der Flasche.Preferably, a plurality of further substantially vertically extending material weakenings are provided in the deformation zone distributed over the circumference, as are known per se from the cited prior art. These material weakenings facilitate expansion of the deformation zone during the first opening of the bottle.

Bevorzugt sind am Umfang verteilt mehrere als Originalsicherungselemente dienende Materialschwächungen angeordnet. Hierdurch ist unabhängig von der Betrachtungsrichtung der Verschlußkappe eindeutig feststellbar, ob die Flasche noch original verschlossen ist oder ob diese bereits geöffnet war.A plurality of material weakenings serving as original securing elements are preferably arranged distributed on the circumference. As a result, regardless of the viewing direction of the cap is clearly determined whether the bottle is still sealed original or whether it was already open.

Im Gegensatz zum eingangs gewürdigten Stand der Technik weist der Schaft bevorzugt keine horizontal verlaufende Schlitze mit dazwischen liegenden Stegen auf. Hierdurch ist eindeutig gesichert, dass sich nicht der obere Teil der Verschlußkappe vom unteren Teil abtrennt, was das Entfernen des unteren Teils von der Flasche und somit das getrennte Recyclieren von Metall und Glas erschweren würde. Die erfindungsgemäße Verschlußkappe läßt sich ohne Zuhilfenahme von Werkzeugen vollständig unter Aufweitung der Verformungszone beim ersten Öffnen von der Flasche abschrauben. Sie läßt sich zum Wiederverschließen mehrfach wieder dicht auf die Flasche aufschrauben und ist schließlich beim Recyclieren vollständig von der Flasche entfernbar. Somit wird die Altglasschmelze freigehalten von unnötig hohen Aluminiumanteilen. Die einteilige Entfernbarkeit des Verschlusses ermöglicht außerdem dessen Verwendung auch bei Flaschen des Mehrwegsystems.In contrast to the acknowledged prior art, the shaft preferably has no horizontally extending slots with webs lying therebetween. This clearly ensures that the upper part of the cap does not separate from the lower part, which means removing the lower part of the bottle and thus recycling the metal and glass separately would complicate. The closure cap according to the invention can be completely unscrewed without the aid of tools under expansion of the deformation zone during the first opening of the bottle. It can be re-closed several times to screw tightly on the bottle and is finally completely removable from the bottle during recycling. Thus, the waste glass melt is kept free from unnecessarily high aluminum content. The one-piece removability of the closure also allows its use in bottles of the reusable system.

Zum Erleichtern des Öffnen und Schließens ist vorgesehen, dass die Verschlußkappe im Bereich des Seitenrandes des Deckels und/oder unterhalb des Anrollbereiches wenigstens einen Rändel aufweist. Durch einen solchen Rändel wird in an sich bekannter Weise die Griffigkeit erhöht, wobei zwei voneinander beabstandete Rändel hierbei besonders bevorzugt sind.To facilitate the opening and closing it is provided that the closure cap in the region of the side edge of the lid and / or below the Anrollbereiches has at least one knurl. By such a knurl, the grip is increased in a conventional manner, with two spaced apart knurls are particularly preferred.

Die für das Originalitätsicherungselement dienende Materialschwächung weist bevorzugt ausgehend von der ungeschwächten Basis, die bevorzugt unmittelbar an die untere Sicke heranreicht, eine Kontur in Gestalt einer regelmäßigen geometrischen Figur auf, wie beispielsweise der eines Dreiecks, eines Rechtecks, eines Trapez, eines Halbkreises, einer Halb-Ellipse oder dergleichen. Eine derartige regelmäßige geometrische Figur ist an einem entsprechenden Rollierwerkzeug in einfacher Weise herstellbar.The material weakening serving for the tamper-evident element preferably has a contour in the form of a regular geometric figure, for example that of a triangle, a rectangle, a trapezoid, a semicircle, a half, starting from the unattenuated base, which preferably extends directly to the lower bead -Ellipse or the like. Such a regular geometric figure can be produced in a simple manner on a corresponding roller burnishing tool.

Die Verwendung einer bestimmten Kontur oder einer bestimmten Abfolge mehrerer wechselnder Konturen kann dabei auch als Codierung für den Flascheninhalt dienen. Ähnlich wie bei einem Barcode können dabei Eigenschaften, Abfüllzeitpunkt, Haltbarkeit, Abfüllort oder ähnliches in codierter Weise an der Verschlußkappe als Information hinterlegt werden.The use of a specific contour or a specific sequence of several alternating contours can also serve as coding for the bottle contents. Similar to a barcode, characteristics, filling time, shelf life, filling location or the like can be deposited in coded manner on the closure cap as information.

Eine erfindungsgemäße Verschlußkappe wird bevorzugt zum Verschließen einer Weinflasche verwendet. Nachdem dies bereits bei Weinflaschen des unteren Preissegments mit kurzen Verschlußkappen üblich ist, ist eine erfindungsgemäße Verschlußkappe auch in hervorragender Weise aufgrund ihrer ausgezeichneten Dicht- und Handhabungseigenschaften zum Verschließen von Weinflaschen des mittleren oder oberen Preissegments geeignet. Die Außenflächen des Schaftes können dabei als Werbeflächen bedruckt werden.A closure cap according to the invention is preferably used for closing a wine bottle. Already with wine bottles of the Lower price segment with short caps is common, a cap according to the invention is also in an excellent manner due to their excellent sealing and handling properties suitable for closing wine bottles of the middle or upper price segment. The outer surfaces of the shaft can be printed as advertising space.

Eine andere bevorzugte Verwendung sieht vor, dass eine derartige Verschlußkappe zum Verschließen einer Spirituosen enthaltenden Flasche dient.Another preferred use provides that such a closure cap serves to close a bottle containing spirits.

Wenn vorstehend im Zusammenhang mit der Anwendung eines erfindungsgemäßen Verschlusses von einer Flasche als zu verschließendem Behälter gesprochen wird, so ist für den Fachmann klar, dass anstelle einer Flasche auch jeder andere Behälter, der mit einem Schraubverschluß versehen ist, Verwendung finden könnte und insoweit auch vom Schutz der Ansprüche umfaßt sein soll. Dies gilt beispielsweise für Behälter, Kanister, Gebinde, Blister, Tüten oder sonstige Verpackungen aus Metall, Glas, Kunststoff, Pappe oder anderen Materialien bzw. Verbundmaterialien. In diesen können außer den bereits erwähnten alkoholischen Getränken, wie Wein oder Spirituosen auch nichtalkoholische Getränke, flüssige oder nicht flüssige Lebensmittel, wie Essig, Öl, Salz, Zucker, Mehl oder dergleichen oder auch Stoffe aus dem Bereich der Chemie oder der Medizin beherbergt sein. Für alle Anwendungsfälle ist es vorteilhaft, dass jederzeit erkennbar ist, ob eine noch nicht angebrochene Originalverpackung vorliegt. Weiterhin ist für alle Anwendungsfälle vorteilhaft, dass das durch einen erfindungsgemäßen Verschluß verschlossene Gut sowohl vor dem ersten Öffnen des jeweiligen Behälters als auch nach jedem Wiederverschließen geruchs-, geschmacks- und feuchtigkeitsgeschützt verschlossen ist, so dass weder der Inhalt durch äußere Einflüsse beeinträchtigt wird, noch die Umgebung durch den Inhalt.When spoken above in connection with the application of a closure according to the invention of a bottle as a container to be closed, it is clear to the skilled person that instead of a bottle and any other container which is provided with a screw, could find use and extent of the Protection of the claims should be included. This applies, for example, to containers, canisters, containers, blisters, bags or other packaging made of metal, glass, plastic, cardboard or other materials or composite materials. In addition to the aforementioned alcoholic beverages, such as wine or spirits, non-alcoholic beverages, liquid or non-liquid foods, such as vinegar, oil, salt, sugar, flour or the like, as well as substances from the chemical or medical field can be accommodated therein. For all applications, it is advantageous that it is always apparent whether an unopened original packaging is present. Furthermore, it is advantageous for all applications that the closed by a closure according to the invention good, odor, taste and moisture is sealed both before the first opening of the respective container as well as after each resealing, so that neither the content is affected by external influences, nor the environment through the content.

Der verwendete Begriff "Verschlußkappe" ist auch nicht im engeren Sinn als eine rein metallische Verschlußkappe zu verstehen, auch wenn diese bevorzugt aus Aluminium oder einer Aluminiumlegierung hergestellt wird. Selbstverständlich könnten auch Bleche, Kunststoffe oder Folien aus Verbundmaterialien zur Herstellung einer Verschlußkappe Verwendung finden, deren Material eine plastische Verformung ermöglicht und ein Herausbrechen bzw. -klappen der Originalitätssicherungselemente bei der Erstöffnung gewährleistet.The term "cap" is not to be understood in the narrower sense as a purely metallic cap, even if it is preferably made of aluminum or an aluminum alloy. Of course, it would also be possible to use metal sheets, plastics or films made of composite materials for the production of a closure cap, the material of which permits plastic deformation and ensures breaking-out or folding-in of the tamper-evident elements during initial opening.

Wenn in Zusammenhang mit den Originalitätssicherungselementen von Materialschwächungen mit einer geschlossenen Kontur gesprochen wird, ist für den Fachmann klar, dass auch Konturen mit geringfügigen ungeschwächten Unterbrechungen ein äquivalentes Ergebnis erzeugen können, wenn das Material an den Unterbrechungen insgesamt so schwach ist, dass es dem Herausklappen der Originalitätssicherungselemente keinen entscheidenden Widerstand entgegensetzt und bei der Erstöffnung durchtrennt wird.When talking about the tamper-evident features of closed-contour material weakening, it will be apparent to those skilled in the art that even contours with slight uninterrupted discontinuities can produce an equivalent result if the material at the breaks is so weak overall that it can fold out Tamper-evident elements no decisive resistance opposes and is cut at the first opening.

Eine Verschlußkappe 1 setzt sich aus einem Deckel 2 und einem insgesamt mit 12 bezeichneten Schaft zusammen. Sie wird in bekannter Weise aus einer Rohtafel aus Aluminium bzw. einer Aluminiumlegierung von einer Dicke d1 von etwa 0,21 mm bis 0,24 mm hergestellt. Derartige Tafeln werden zunächst bedruckt und/oder lackiert und - falls erforderlich - in Streifen geschnitten. Durch Stanzen kreisrunder Ausschnitte mit anschließendem Tiefziehen werden die Rohkappen hergestellt, auf die anschließend durch Rollieren Sicken, Rändel, Materialschwächungen oder dergleichen angeformt werden. Dabei dient eine den Deckel 2 nach unten begrenzende, nach innen vorspringende Sicke 3 bevorzugt zur Befestigung eines nicht dargestellten Dichtungselements, das auf der Innenseite des Deckels 2 entweder als eingelegte Dichtscheibe, als Ventileinsatz oder als Kunststoffschaum (PVC-Compound oder PVC-freie Dichtungsmasse) ausgebildet ist. Die Dichtungselemente können auf der der Flaschenmündung zugewandten Seite Dichtungslippen, -rippen oder ähnliches aufweisen.A closure cap 1 is composed of a cover 2 and a shaft designated overall by 12. It is produced in a known manner from a raw sheet of aluminum or an aluminum alloy of a thickness d 1 of about 0.21 mm to 0.24 mm. Such panels are first printed and / or painted and - if necessary - cut into strips. By punching circular cutouts followed by thermoforming the raw caps are produced, are then formed by rolling beads, knurls, material weakenings or the like. In this case, the cover 2 downwardly bounding, inwardly projecting bead 3 is preferably used for fastening a sealing element, not shown, on the inside of the lid 2 either as inserted sealing disc, as a valve core or as a plastic foam (PVC compound or PVC-free sealant) is trained. The sealing elements may have sealing lips, ribs or the like on the side facing the bottle mouth.

An die Sicke 3 schließt sich nach unten ein Anrollbereich 4 an, in welchem später beim Anwender (im Normalfall beim Hersteller oder Abfüller) nach Aufsetzen der Verschlußkappe das Gewinde an dieser auf der Flasche angerollt wird. Zur Erhöhung der Griffigkeit beim Öffnen und Wiederverschließen ist im Bereich des Deckels 2 am Außenrand ein erster oberer Rändel 5 vorgesehen. Dieser wird bevorzugt durch einen zweiten unteren Rändel 6 ergänzt, der sich nach unten an den Anrollbereich 4 für das Gewinde anschließt.At the bead 3 closes down to a Anrollbereich 4, in which later the user (normally the manufacturer or bottler) after placing the cap, the thread is rolled at this on the bottle. To increase the grip when opening and reclosing a first upper knurled 5 is provided in the region of the lid 2 at the outer edge. This is preferably supplemented by a second lower knurl 6, which connects down to the Anrollbereich 4 for the thread.

Unterhalb des unteren Rändels 6 ist eine nach außen vorspringende Sicke 7 angeformt, welche eine Bördelzone 8 begrenzt. Die Bördelzone 8 wird nach unten von einer weiteren nach außen vorspringenden Sicke 9 begrenzt. Der zwischen den Sicken 7 und 9 liegende Bereich der Bördelzone 8 ist als Verformungszone 10 ausgebildet, welche beim Anwender durch ein Anrollwerkzeug unter das sich an das Gewinde anschließende Bördelband am Flaschenhals nach innen verformt und angerollt wird.Below the lower knurl 6 an outwardly projecting bead 7 is formed, which limits a crimping zone 8. The crimping zone 8 is bounded below by a further outwardly projecting bead 9. The lying between the beads 7 and 9 area of the crimping zone 8 is formed as a deformation zone 10, which is deformed by the user by a roll-on under the subsequent to the thread crimping tape on the bottle neck and rolled inwards.

In der Verformungszone 10 sind zum einen vertikale Materialschwächungen 14 vorgesehen, von denen bevorzugt mehrere gleichmäßig am Umfang verteilt sind und zum anderen wenigstens eine Materialschwächung 11, die als Originalitätssicherungselement verwendet wird. Vorzugsweise sind ebenfalls mehrere als Originalitätssicherungselemente dienende Materialschwächungen 11 am Umfang der Verformungszone 10 verteilt und zu den vertikalen Materialschwächungen 14 versetzt angeordnet.In the deformation zone 10, on the one hand, vertical material weakenings 14 are provided, of which preferably several are distributed uniformly around the circumference and at least one material weakening 11, which is used as a tamper-evident element. Preferably, a plurality of material weakenings 11 serving as tamper-evident elements are likewise distributed on the circumference of the deformation zone 10 and offset relative to the vertical weakenings 14 of material.

Die Materialschwächungen 14 dienen der Erleichterung der Sickenbildung in diesem Bereich beim Anrollen und auch der Erleichterung des Aufweitens der Verformungszone 10 beim erstmaligen Öffnen der Flasche. Bei einem solchen erstmaligen Öffnen der Flasche reißen die beschriebenen Materialschwächungen 11 an ihren jeweiligen Konturen auf, das Originalitätssicherungselement löst sich bis auf die geschlossene untere Basislinie 15 aus der Verformungszone 10 heraus und wird beim Abdrehen des Verschlusses 1 vom Mundstück der Flasche über die Basislinie 15 auf die Innenseite des Schaftes abgeklappt. Es entstehen dadurch den Konturen dieser Materialschwächungen 11 entsprechende Fenster in der Verschlußkappe 1.The material weakenings 14 serve to facilitate the beading in this area when rolling on and also to facilitate the expansion of the deformation zone 10 when opening the bottle for the first time. In such a first-time opening of the bottle, the described material weakenings 11 tear at their respective contours, the tamper-evident element dissolves out of the deformation zone 10 except for the closed lower base line 15 and becomes on the base line 15 when the closure 1 is twisted off The inside of the shaft folded down. This results in the contours of these material weakenings 11 corresponding window in the cap. 1

Wie der Fig. 1 zu entnehmen ist, erstrecken sich die als Originalitätssicherungselemente verwendeten Materialschwächungen 11 ausgehend von ihrer unteren geschlossenen, ungeschwächten Basislinie 15, die an die untere Sicke 9 angrenzt über maximal die untere Hälfte der Verformungszone 10 in einer geschlossenen Kontur nach oben. Dabei ist nur diese geschlossene Kontur als Einkerbung in das Material eingebracht. Als Konturformen eignen sich bevorzugt regelmäßige geometrische Figuren, von denen eine begrenzte Auswahl beispielhaft in Fig. 2 dargestellt ist. Dort finden sich Materialschwächungen mit einer halbkreisförmigen Kontur 111, einer dreieckigen Kontur 112, der bereits aus Fig. 1 bekannten rechteckigen Kontur 116, einer schild- oder blattförmigen Kontur 114, einer Tonnengewölbeförmigen Kontur 113, einer quadratischen Kontur 115 und einer trapezförmigen Kontur 117. Diese Konturen sind, wie Fig. 3 verdeutlicht, als Einkerbungen in das Material der Verschlußkappe 1 derart eingeformt, dass von der ursprünglichen Dicke d1 von etwa 0,21 mm bis 0,24 mm eine Dicke d2 erhalten bleibt, die etwa 0,10 mm oder weniger beträgt. Durch die Anordnung im unteren Bereich der Verformungszone 10 ist sichergestellt, dass beim Abdrehen des Verschlusses vom Mundstück der Flasche die von den Konturen 111 bis 117 umgebenen Materialbereiche nach innen klappen, so dass keine nach außen vorragenden Metallteile eine Verletzungsgefahr darstellen. Die Materialschwächungen 11 erzeugen beim erstmaligen Öffnen ausgebrochene Fenster im Verformungsbereich 10, die nicht wieder verschließbar sind und somit eindeutig und irreversibel eine Öffnung der Flasche signalisieren.As can be seen from FIG. 1, the material weakenings 11 used as tamper-evident elements extend upwards from their lower closed, unattenuated base line 15 which adjoins the lower bead 9 over a maximum of the lower half of the deformation zone 10 in a closed contour. Only this closed contour is introduced as a notch in the material. As contour shapes are preferably suitable regular geometric figures, of which a limited selection is shown by way of example in Fig. 2. There are material weaknesses with a semicircular contour 111, a triangular contour 112, the already known from Fig. 1 rectangular contour 116, a shield or leaf-shaped contour 114, a barrel-shaped contour 113, a square contour 115 and a trapezoidal contour 117. This Contours are, as Fig. 3 illustrates, as notches in the material of the closure cap 1 is formed such that from the original thickness d 1 of about 0.21 mm to 0.24 mm a thickness d 2 is maintained which is about 0.10 mm or less. The arrangement in the lower region of the deformation zone 10 ensures that, when the closure is twisted off the mouthpiece of the bottle, the material regions surrounded by the contours 111 to 117 fold inwards, so that no metal parts projecting outwards present a risk of injury. The material weakenings 11 produce windows which have broken open in the first opening in the deformation area 10, which can not be closed again and thus clearly and irreversibly signal an opening of the bottle.

An die untere Sicke 9 schließt sich bevorzugt ein unterer Schaftbereich 13 an, der insbesondere beim Verschließen von Weinflaschen oder Spirituosenflaschen bedruckt verwendet wird. Zum Bedrucken dieses Bereiches wird bevorzugt eine Seitenbedruckungsmaschine verwendet.At the lower bead 9 is preferably followed by a lower shaft portion 13, which is used in particular printed on the closure of wine bottles or bottles of spirits. For printing on this area, a page printing machine is preferably used.

Die erfindungsgemäße Verschlußkappe ist aufgrund ihrer hervorragenden Handhabungseigenschaften beim erstmaligen Öffnen und beim Wiederverschließen sowie aufgrund ihres fälschungssicheren Originalitätssicherungselements auch zum Verschließen von Flaschen mit hochwertigen Getränken geeignet. Hierfür bieten sich sowohl Spirituosen als auch Weine des mittleren und oberen Preissegments an. Eine metallische Verschlußkappe weist dabei gegenüber einem Kork eindeutige Vorteile bezüglich eines prozeßsicheren dichten Verschließens und des ebenso dichten Wiederverschließens auf, wobei nach dem Wiederverschluß aufgrund der hervorragenden Dichteigenschaften auch eine liegende Lagerung möglich ist.The cap according to the invention is also suitable for sealing bottles with high-quality drinks due to their excellent handling properties when first opened and resealed and because of their tamper-proof tamper-evident element. Both spirits and wines of the middle and upper price segment are suitable for this. A metallic cap has in this case over a cork clear advantages in terms of a process-tight tight closure and equally dense resealing, which after reclosing due to the excellent sealing properties and a horizontal storage is possible.
