The tamper-proof band (3) is connected by connection webs (4) to the closure cap (2). In this case, primary connection webs (4a) and secondary connection webs (4b) are provided. The secondary connection webs (4b) are dimensioned such that they tear and are destroyed under tensile loading far more easily than the primary connection webs (4a). <IMAGE>

Description

Die Erfindung betrifft einen Garantieverschluss sowie ein Verfahren und eine Vorrichtung zur Herstellung eines Garantieverschlusses. Garantieverschlüsse zum Verschliessen von Behältern sind in Vielzahl bekannt und gebräuchlich. In der Regel ist ein derartiger Verschluss mit einem Garantieband versehen, welches durch eine Anzahl von Verbindungsstegen mit dem Verschluss trennbar verbunden ist. Das Garantieband wird dabei mittels eines Rückhalte-Elements, meistens eines vorstehenden Wulstes, einer Hinterschneidung, einzelnen Nocken, mit dem Behälterhals in Eingriff gebracht. Zusätzliche Fixierung lässt sich z.B. auch durch Warm-Schrumpfen erreichen. Auch ist es bekannt, Kombinationen verschieden geformter Rückhalte-Elemente vorzusehen. Das Garantieband kann dabei z.B. bei Einweg-Getränkeflaschen so ausgebildet sein, dass es vollständig von der Verschlusskappe getrennt wird und am Flaschenhals bleibt. Anderseits ist es auch z.B. aus der US-PS-5,074,425 bekannt, das Garantieband mit festen Verbindungsstegen zu versehen, durch welche es am Garantieverschluss gehalten wird, nachdem die abreissbaren Verbindungsstege durchtrennt wurden. Derartige Garantiebänder sind deshalb meistens mit einer oder mehreren vertikalen Sollreisslinien versehen.The invention relates to a guarantee closure and to a method and a device for producing a guarantee closure. Warranty closures for closing containers are known and used in large numbers. As a rule, such a closure is provided with a guarantee band which is connected to the closure in a separable manner by a number of connecting webs. The guarantee band is brought into engagement with the container neck by means of a retaining element, usually a protruding bead, an undercut, individual cams. Additional fixation can e.g. can also be achieved by heat shrinking. It is also known to provide combinations of differently shaped retaining elements. The guarantee tape can be e.g. be designed in the case of disposable beverage bottles so that it is completely separated from the cap and remains on the neck of the bottle. On the other hand, it is also e.g. from US-PS-5,074,425 to provide the guarantee tape with fixed connecting webs, by means of which it is held on the guarantee closure after the tear-off connecting webs have been severed. Such guarantee tapes are therefore usually provided with one or more vertical tear lines.

Beim erstmaligen Öffnen wird das Garantieband wenigstens vorübergehend am Flaschenhals zurückgehalten, so dass beim Öffnen des Verschlusses die Verbindungsstege reissen und das Öffnen anzeigen.When opening for the first time, the guarantee band is at least temporarily held back on the bottle neck, so that when the closure is opened, the connecting webs tear and indicate that it has been opened.

Derartige Verschlüsse können einstückig im Kunststoff-Spritzgussverfahren zusammen mit dem Garantieband hergestellt werden. Es ist aber auch bekannt, an Verschluss-Rohlingen nachträglich eine Schwächungslinie zwischen der Verschluss-Kappe und dem Garantieband anzubringen. Derartige Vorrichtungen und Verfahren sind aus der US-PS-3,673,761 (Leitz/CIBA-Geigy AG), der DE-OS-14 82 603 (Teillac/ALCA S.A.) oder der US-PS-4,895,265 (LUC et al./The West Co.) bekannt.Such closures can be produced in one piece in a plastic injection molding process together with the guarantee tape. However, it is also known to subsequently add a weakening line between the closure cap on blank blanks and attach the guarantee tape. Such devices and methods are known from US Pat. No. 3,673,761 (Leitz / CIBA-Geigy AG), DE-OS-14 82 603 (Teillac / ALCA SA) or US Pat. No. 4,895,265 (LUC et al./The West Co.) known.

Bei diesen Verschlüssen wird die Schwächungslinie mittels eines Schneidwerkzeugs vor oder nach dem Aufsetzen des Verschluss-Rohlings auf einen Behälter angebracht. Als Schneidwerkzeug kann ein Messer, eine erhitzte Schneide oder auch ein rotierendes, kreissägeartiges Schneidwerkzeug dienen. Die Materialschwächung kann dabei an einem erwärmten Verschluss-Rohling oder auch am kalten Material angebracht werden. Art des Schneidwerkzeugs und Verfahrensparameter, insbesondere auch Schneidtemperatur, hängen ersichtlicherweise von der Art des verwendeten Kunststoffs, der Grösse und der Art der Schwächungslinie, der Geschwindigkeit des Verfahrens etc., ab. Auch Laser-Schneidwerkzeuge sind bei solchen Verfahren einsetzbar.With these closures, the line of weakness is applied to a container by means of a cutting tool before or after the blank blank is placed on it. A knife, a heated cutting edge or a rotating circular saw-type cutting tool can serve as the cutting tool. The weakening of the material can be applied to a heated blank blank or to the cold material. The type of cutting tool and process parameters, in particular also the cutting temperature, obviously depend on the type of plastic used, the size and type of the line of weakness, the speed of the process, etc. Laser cutting tools can also be used in such processes.

Anderseits sind auch Garantieverschlüsse aus Metall bekannt, bei denen nachträglich ein Garantie-Element befestigt wird. Das Garantie-Element ist dabei in der Regel ringförmig mit einem ersten Halte-Abschnitt ausgebildet, mit welchem es formschlüssig mit der Verschlusskappe in Verbindung gebracht werden kann. Der Halte-Abschnitt - und damit die Verschlusskappe - ist mittels Verbindungsstegen mit dem Garantieband verbunden.On the other hand, guarantee closures made of metal are also known, in which a guarantee element is subsequently attached. The guarantee element is usually ring-shaped with a first holding section, with which it can be positively connected to the closure cap. The holding section - and thus the closure cap - is connected to the guarantee band by means of connecting webs.

Es sind auch noch andere Methoden zur Herstellung von Garantieverschlüssen, wie z.B. Compression-molding, Zweikomponenten-Spritzgiessen und dergleichen bekannt.There are also other methods of making guarantee closures, such as Compression molding, two-component injection molding and the like are known.

Eine Schwierigkeit bei derartigen Verschlüssen besteht darin, dass die Verbindungsstege einerseits so stabil ausgebildet sein müssen, dass sie weder bei der Entformung aus einem Werkzeug, noch beim Lagern, Manipulieren oder beim Aufsetzen des Verschlusses auf einen Behälter zerstört oder beschädigt werden. Andererseits sollen sie aber zuverlässig möglichst bei jeder geringfügigen Manipulation, jedenfalls beim erstmaligen Öffnen oder einem Öffnungsversuch, reissen oder brechen. Aus der US-PS-4,322,009 (Mumford/Owens-Illinois Inc.) ist deshalb z.B. ein Garantieverschluss bekannt, dessen Verbindungsstege gleicher Dicke und Dimension so erzeugt werden, dass Garantieband und Garantieverschluss nur durch einen engen Spalt voneinander getrennt sind und beim Aufschrauben miteinander in Kontakt kommen können.One difficulty with closures of this type is that the connecting webs have to be so stable on the one hand that they cannot be removed from a tool, stored, manipulated or put on of the closure on a container can be destroyed or damaged. On the other hand, they should reliably tear or break with every slight manipulation, at least when opening for the first time or trying to open them. From US-PS-4,322,009 (Mumford / Owens-Illinois Inc.), for example, a guarantee closure is therefore known, the connecting webs of the same thickness and dimension are produced in such a way that the guarantee band and the guarantee closure are separated from one another only by a narrow gap and when screwed together with one another Can come in contact.

Aus der US-PS-5,074,425 (Wüstman et al./Crown Cork AG) ist ein Garantieverschluss bekannt, bei welchem die Verbindungsstege an einer der Aufreiss-Position zugewandten Seite geschwächt sind.A guarantee closure is known from US Pat. No. 5,074,425 (Wüstman et al./Crown Cork AG), in which the connecting webs are weakened on a side facing the tear-open position.

Der Erfindung liegt die Aufgabe zugrunde, Garantieverschlüsse, insbesondere die verschiedenen, vorstehend beschriebenen Arten von Garantieverschlüssen so zu verbessern, dass Verbindungsstege geschaffen werden, die einerseits empfindlich und bei einem Manipulationsversuch leicht beschädigbar sind und die andererseits stabil beim Lagern und Entformen sind.The invention has for its object to improve guarantee closures, in particular the various types of guarantee closures described above, in such a way that connecting webs are created which are sensitive on the one hand and easily damaged during an attempted manipulation and which on the other hand are stable during storage and removal from the mold.

Erfindungsgemäss wird diese Aufgabe in erster Linie gemäss Kennzeichen der Patentansprüche gelöst.According to the invention, this object is primarily achieved according to the characteristics of the claims.

Durch die Anordnung von Primär- und Sekundär-Verbindungsstegen mit unterschiedlicher Belastbarkeit wird insgesamt eine für die Herstellung, Lagerung und Manipulation ausreichend feste Verbindung zwischen Garantieband und Verschlusskappe gewährleistet. Beim Öffnen des Behälters und bei einer Belastung der Verbindungsstege auf Zug werden jedoch die schwächeren Verbindungsstege praktisch sofort zerstört. Vor allem wenn die Sekundär-Verbindungsstege dünneren Querschnitt oder jedenfalls dünneren Minimalquerschnitt aufweisen als die Primär-Verbindungsstege, lassen Sie nur eine geringfügige Materialdehnung zu, bevor sie brechen. Die Sekundär-Verbindungsstege werden auch beim unbefugten Manipulieren leichter zerstört, als die Primär-Verbindungsstege. Sobald jedoch die Sekundär-Verbindungsstege zerstört sind, müssen die Primär-Verbindungsstege beim Öffnen des Behälters die gesamte Zug-Beanspruchung aufnehmen, so dass sie in der Folge ebenfalls reissen. Die Erfindung sieht dabei vor, dass im Zwischenraum zwischen Primär-Verbindungsstegen ein Sekundär-Verbindungs steg, vorzugsweise jedoch zwei bis vier Sekundär-Verbindungsstege angeordnet sind, welche bei Zugbeanspruchung die Last mit den Primär-Verbindungsstegen teilen und nach dem Reissen die Gesamtlast auf die Primär-Verbindungsstege verlagern.The arrangement of primary and secondary connecting webs with different load capacities ensures that the connection between the guarantee band and the sealing cap is sufficiently firm for manufacture, storage and manipulation. However, when the container is opened and the connecting webs are subjected to tension, the weaker connecting webs are destroyed almost immediately. Especially if the secondary connecting webs have a thinner cross-section or in any case thinner minimum cross-section than the primary connecting webs, leave only a slight material stretch before they break. The secondary connecting webs are more easily destroyed when the tamper is manipulated than the primary connecting webs. However, as soon as the secondary connecting webs are destroyed, the primary connecting webs have to absorb the entire tensile stress when the container is opened, so that they also tear as a result. The invention provides that a secondary connecting web is arranged in the space between primary connecting webs, but preferably two to four secondary connecting webs are arranged, which share the load with the primary connecting webs under tensile stress and, after tearing, the total load on the primary - Relocate connecting bridges.

Gute Lastverteilung lässt sich auch erreichen, wenn jeweils abwechselnd Zwischenräume zwischen Primär-Verbindungsstegen mit Sekundär-Verbindungsstegen bzw. mit keinen Sekundär-Verbindungsstegen versehen sind.Good load distribution can also be achieved if alternating spaces between primary connecting webs are alternately provided with secondary connecting webs or with no secondary connecting webs.

Die unterschiedliche Belastbarkeit von Sekundär-Verbindungsstegen und Primär-Verbindungsstegen lässt sich vor allem durch unterschiedliche Materialdicke und/oder durch Schwächungszonen in den Verbindungsstegen verwirklichen. So können z.B. die Sekundär-Verbindungsstege durch Einschnitte oder Materialverjüngungen geschwächt werden und die Primär-Verbindungsstege bei im übrigen gleicher Materialdicke ungeschwächt ausgebildet werden. Anderseits ist es auch denkbar, sowohl die Sekundär-Verbindungsstege als auch die Primär-Verbindungsstege mit Materialschwächungen zu versehen, wobei die Sekundär-Verbindungsstege stärker geschwächt werden, als die Primär-Verbindungsstege.The different resilience of secondary connecting webs and primary connecting webs can be realized primarily by different material thickness and / or by weakening zones in the connecting webs. For example, the secondary connecting webs are weakened by incisions or material tapering, and the primary connecting webs are formed without weakening while the material thickness is otherwise the same. On the other hand, it is also conceivable to provide both the secondary connecting webs and the primary connecting webs with material weaknesses, the secondary connecting webs being weakened more than the primary connecting webs.

Verfahrensmässig lässt sich die Erfindung besonders einfach realisieren, wenn an einem Verschluss-Rohling mit zylindrischem Wandabschnitt und Kappenboden an vorbestimmbaren Umfangsbereichen Schwächungszonen angebracht werden, wobei unterschiedliche Schwächungszonen zu Primär-Verbindungsstegen und Sekundär-Verbindungsstegen führen, die unterschiedliche Materialfestigkeit aufweisen. So lassen sich z.B. Verbindungsstege durch Materialschnitte im zylindrischen Wandabschnitt erzeugen, wobei die Materialstärke der verbleibenden Verbindungsstege durch die Schnitt-Tiefe variierbar ist.In terms of the method, the invention can be implemented particularly simply if weakening zones are attached to a blank blank with a cylindrical wall section and a cap base at predeterminable circumferential areas, different weakening zones forming primary connecting webs and secondary connecting webs that have different material strength. For example, connecting webs can be produced by material cuts in the cylindrical wall section, the material thickness of the remaining connecting webs being variable by the depth of cut.

Derartige Materialschwächungen lassen sich besonders vorteilhaft durch eine Trennvorrichtung mit einer Schneide anbringen, in welcher unterschiedlich geformte Aussparungen zum Formen der Primär- und der Sekundär-Verbindungsstege vorgesehen sind. Die Schneide kann dabei in bekannter Weise beheizt werden.Such material weakenings can be applied particularly advantageously by means of a separating device with a cutting edge, in which differently shaped recesses are provided for forming the primary and the secondary connecting webs. The cutting edge can be heated in a known manner.

Selbstverständlich lässt sich die Materialschwächung auch auf andere Weise, z.B. mittels Fräsen, durch beheizte Zangen oder durch Laser-Schneidgeräte erzeugen. Auch wäre es z.B. denkbar, Garantieverschlüsse mit identischen Verbindungsstegen im Spritzgussverfahren oder im Compression-molding-Verfahren herzustellen und nachträglich einzelne der Verbindungsstege zu schwächen, insbesondere einzuschneiden, um Sekundär-Verbindungsstege zu erzeugen. Alternativ wäre es auch denkbar, Verschlusskappe und Garantieband separat herzustellen und das Garantieband nachträglich im Bereich der Verbindungsstege mit der Verschlusskappe zu verbinden, z.B. formschlüssig einzurasten, zu verkleben oder auch die Verbindungsstege zu verschweissen.Of course, the weakening of the material can also be done in other ways, e.g. using milling, heated tongs or laser cutters. It would also be e.g. It is conceivable to manufacture guarantee closures with identical connecting webs in the injection molding process or in the compression molding process and to subsequently weaken, in particular cut, individual ones of the connecting webs in order to produce secondary connecting webs. Alternatively, it would also be conceivable to manufacture the sealing cap and the guarantee band separately and to subsequently connect the guarantee band in the region of the connecting webs to the sealing cap, e.g. to engage in a positive fit, to glue or to weld the connecting webs.

Gemäss Figur 1 und 2 besteht ein im Spritzgussverfahren hergestellter Garantieverschluss 1 aus einer Verschlusskappe 2 und einem Garantieband 3. Das Garantieband 3 ist durch Verbindungsstege 4 mit der Verschlusskappe 2 verbunden. Die Schraubkappe 2 wird auf einen Behälter-Hals 6 geschraubt, wobei ein Wulst 7 des Garantiebands 3 formschlüssig über ein als Gegen-Wulst ausgebildetes Rückhalte-Element 8 am Behälter-Hals 6 schnappt. Die Verbindungsstege 4 sind als Primär-Verbindungsstege 4a und Sekundär-Verbindungsstege 4b ausgebildet. Wie aus Figur 2 und 3 hervorgeht, weisen die Primär-Verbindungsstege 4a einen wesentlich grösseren Durchmesser und damit grösseren Querschnitt auf, als die Sekundär-Verbindungsstege 4b. Dies bewirkt, dass beim Öffnen der Flasche zunächst die relativ dünnen und aufgrund des geringen Querschnitts kaum elastisch streckbaren Sekundär-Verbindungsstege 4b reissen, wodurch die auf die Primär-Verbindungsstege 4a ausgeübte Kraft sprungartig steigt und die Primär-Verbindungsstege 4a ebenfalls zu reissen beginnen. Auf die vor allem in Figur 2 und Figur 3b dargestellte Weise beginnt das Garantieband zunächst an einer Stelle zu reissen. Mit fortschreitendem Reissen der Sekundär-Verbindungsstege 4b reissen auch alle Primär-Verbindungsstege 4a, so dass der Garantieverschluss 1 vom Behälter-Hals 6 getrennt werden kann.According to FIGS. 1 and 2, a guarantee closure 1 produced by injection molding consists of a closure cap 2 and a guarantee band 3. The guarantee band 3 is connected to the closure cap 2 by connecting webs 4. The screw cap 2 is screwed onto a container neck 6, with a bead 7 of the guarantee band 3 being form-fitting as a counter-bead retaining element 8 snaps onto the container neck 6. The connecting webs 4 are designed as primary connecting webs 4a and secondary connecting webs 4b. As can be seen from FIGS. 2 and 3, the primary connecting webs 4a have a substantially larger diameter and thus a larger cross section than the secondary connecting webs 4b. As a result, when the bottle is opened, the relatively thin secondary connecting webs 4b, which can hardly be elastically stretched due to the small cross section, initially tear, whereby the force exerted on the primary connecting webs 4a increases suddenly and the primary connecting webs 4a also begin to tear. In the manner shown primarily in FIG. 2 and FIG. 3b, the guarantee band first begins to tear at one point. With the progressive tearing of the secondary connecting webs 4b, all the primary connecting webs 4a also tear, so that the guarantee closure 1 can be separated from the container neck 6.

Figur 4 zeigt ein abgewandeltes Ausführungsbeispiel, bei welchem Primär-Verbindungsstege 4a sowie eine erste Anzahl von Sekundär-Verbindungsstegen 4b₁ und eine zweite Anzahl von Sekundär-Verbindungsstegen 4b₂ vorgesehen sind. Die Sekundär-Verbindungsstege 4b₁ sind dabei analog den Figuren 1 bis 3a und 3b wesentlich dünner und damit leicher durch Zugbeanspruchung zu zerstören, als die Primär-Verbindungsstege 4a. Die Sekundär-Verbindungsstege 4b₂ sind nochmals dünner ausgebildet, als die ersten Sekundär-Verbindungsstege 4b₁. Damit lässt sich ein stufenweises Reissen der Verbindungsstege, beginnend bei den Verbindungsstegen 4b₂, darauf folgend den Verbindungsstegen 4b₁ und schliesslich den Primär-Verbindungsstegen 4a erreichen.Figure 4 shows a modified embodiment in which primary connecting webs 4a and a first number of secondary connecting webs 4b₁ and a second number of secondary connecting webs 4b₂ are provided. The secondary connecting webs 4b₁ are analogous to Figures 1 to 3a and 3b much thinner and therefore easier to destroy by tensile stress than the primary connecting webs 4a. The secondary connecting webs 4b₂ are made even thinner than the first secondary connecting webs 4b₁. This allows a gradual tearing of the connecting webs, starting at the connecting webs 4b₂, then following the connecting webs 4b₁ and finally the primary connecting webs 4a.

Beim Ausführungsbeispiel gemäss Figur 4 ist ausserdem in bekannter Weise ein wesentlich stärkerer Befestigungs-Steg 9 vorgesehen, der beim Öffnen des Garantieverschlusses nicht reisst. Zusätzlich ist am Garantieband 3 eine Sollbruchstelle 9a vorgesehen, an der das Garantieband 3 vertikal aufreissen kann.In the exemplary embodiment according to FIG. 4, a much stronger fastening web 9 is also provided in a known manner, which does not tear when the guarantee closure is opened. In addition, there is a predetermined breaking point on guarantee strip 3 9a is provided, on which the guarantee band 3 can tear open vertically.

Figur 5 zeigt ein abgewandeltes Ausführungsbeispiel, bei welchem die Sekundär-Verbindungsstege 4b sowohl einen kleineren Querschnitt als die Primär-Verbindungsstege 4a aufweisen, als auch durch Abschrägung einseitig geschwächt sind. Auf diese Weise lässt sich ein Reissen der Sekundär-Verbindungsstege von ihren geschwächten Flanken her steuern.FIG. 5 shows a modified exemplary embodiment in which the secondary connecting webs 4b both have a smaller cross section than the primary connecting webs 4a and are also weakened on one side by beveling. In this way, tearing of the secondary connecting webs can be controlled from their weakened flanks.

Die Figuren 6a und 6b zeigen ein Ausführungsbeispiel, bei welchem ein Primär-Verbindungssteg 4a im wesentlichen den gleichen Querschnitt aufweist, wie ein Sekundär-Verbindungssteg 4b. Beide Verbindungsstege 4a und 4b sind an spitz zulaufenden Flanken 15 geschwächt, so dass von dort her das seitliche Einreissen gefördert wird. Wie sich jedoch aus der Seitenansicht gemäss Figur 6b ergibt, ist der Sekundär-Verbindungssteg 4b zusätzlich durch eine Einkerbung 10 seitlich geschwächt, so dass er vor dem Primär-Verbindungssteg 4a reisst.FIGS. 6a and 6b show an exemplary embodiment in which a primary connecting web 4a has essentially the same cross section as a secondary connecting web 4b. Both connecting webs 4a and 4b are weakened on tapering flanks 15, so that lateral tearing is promoted from there. However, as can be seen from the side view according to FIG. 6b, the secondary connecting web 4b is additionally weakened laterally by a notch 10, so that it tears in front of the primary connecting web 4a.

Die Figuren 7a bis 7c zeigen ein ähnliches Ausführungsbeispiel, bei welchem Primär-Verbindungsstege 4a und Sekundär-Verbindungsstege 4b im oberen Bereich etwa den gleichen Querschnitt aufweisen. Während jedoch der Primär-Verbindungssteg 4a ungeschwächt verläuft, ist auf der Aussenseite des Sekundär-Verbindungsstegs 4b eine als Kerbe 10 ausgebildete Schwächungszone vorgesehen. Figur 7c zeigt dabei schematisch den Schnitt längs der Linie A-A, in Figur 7a in vergrössertem Massstab, woraus der Verlauf der Kerbe 10 zu entnehmen ist.FIGS. 7a to 7c show a similar exemplary embodiment, in which primary connecting webs 4a and secondary connecting webs 4b have approximately the same cross section in the upper region. However, while the primary connecting web 4a runs without weakening, a weakening zone designed as a notch 10 is provided on the outside of the secondary connecting web 4b. FIG. 7c shows schematically the section along the line A-A, in FIG. 7a on an enlarged scale, from which the course of the notch 10 can be seen.

Figur 8 zeigt eine Anordnung von Primär-Verbindungsstegen 4a und 4b, wobei jeweils abwechselnd in den Zwischenräumen zwischen den Primär-Verbindungsstegen 4a vier Sekundär-Verbindungsstege 4b vorgesehen sind. Die Primär-Verbindungsstege 4a sind etwa gleich dick wie die Wand des Garantiebands 3, wodurch sich sowohl bei Herstellung mit Spritzgusswerkzeugen, als auch bei nachträglichem Schneiden der Verschlüsse gute Herstellungseigenschaften ergeben. Die 4 Sekundär-Verbindungsstege 4b bewirken in der Gesamtheit eine deutliche Verbesserung der Verbindung zwischen Verschlusskappe 2 und Garantieband 3. Durch ihren geringen Querschnitt ist jedoch sichergestellt, dass beim Öffnen des Verschlusses die Sekundär-Verbindungsstege relativ schnell reissen und damit die Gesamt-Belastung auf die Primär-Verbindungsstege 4a übergeben.FIG. 8 shows an arrangement of primary connecting webs 4a and 4b, four secondary connecting webs 4b being provided alternately in the spaces between the primary connecting webs 4a. The primary connecting webs 4a are approximately the same thickness as the wall of the guarantee tape 3, whereby good manufacturing properties result both in manufacture with injection molding tools and in subsequent cutting of the closures. The 4 secondary connecting webs 4b as a whole bring about a significant improvement in the connection between the closure cap 2 and the guarantee band 3. However, their small cross-section ensures that when the closure is opened, the secondary connecting webs tear relatively quickly and thus the total load on the Pass primary connecting webs 4a.

Figur 9 zeigt ein Ausführungsbeispiel, bei welchem in jeden Zwischenraum zwischen je zwei Primär-Verbindungsstegen 4a drei Sekundär-Verbindungsstege 4b angeordnet sind, um das Garantieband an seinem gesamten Umfang zu stabilisieren.FIG. 9 shows an exemplary embodiment in which three secondary connecting webs 4b are arranged in each intermediate space between two primary connecting webs 4a in order to stabilize the entire length of the guarantee band.

Die Figuren 10 und 11 zeigen schematisch, wie sich z.B. ein Verschluss gemäss Figur 9 aus einem Verschluss-Rohling 12 herstellen lässt. Am Verschluss-Rohling 12 greift dabei ein Schneidmesser 13 an, um die Verbindungsstege in der Konfiguration gemäss Figur 9 zu erzeugen. Der Rohling 12 wird durch eine nicht dargestellte Einrichtung am beheizten Schneidmesser 13 so abgerollt, dass das Schneidmesser 13 die Wand des Rohlings 12 durchschneidet. Lediglich im Bereich der Aussparungen 14 durchdringt das Schneidmesser 13 die Wand des Rohlings 12 nicht vollständig, so dass Stege 4a und 4b ausgespart bleiben.Figures 10 and 11 show schematically how e.g. 9 can be made from a blank blank 12 according to FIG. A cutting knife 13 engages the blank blank 12 in order to produce the connecting webs in the configuration according to FIG. 9. The blank 12 is unrolled by a device (not shown) on the heated cutting knife 13 such that the cutting knife 13 cuts through the wall of the blank 12. Only in the area of the cutouts 14 does the cutting knife 13 not completely penetrate the wall of the blank 12, so that webs 4a and 4b are left out.

Figur 11 zeigt die Vorderkante des Schneidmessers 13 in stark vergrösserter Darstellung. Daraus wird ersichtlich, dass am Schneidmesser 13 grössere Aussparungen 14a zur Erzeugung der Primär-Verbindungsstege sowie kleinere Aussparungen 14b zur Erzeugung der Sekundär-Verbindungsstege vorgesehen sind.FIG. 11 shows the front edge of the cutting knife 13 in a greatly enlarged illustration. It can be seen from this that larger cutouts 14a are provided on the cutting knife 13 for producing the primary connecting webs and smaller cutouts 14b for producing the secondary connecting webs.

Selbstverständlich lassen sich durch entsprechende Formgebung der Aussparungen 14, 14a, 14b praktisch beliebige Stegformen und abgestufte Querschnittsformen ausbilden. Dabei können z.B. auch mehr als zwei unterschiedlich schwächere Sekundär-Verbindungsstege oder unterschiedliche Querschnittsformen einzelner Verbindungsstege erzeugt werden.Of course, by shaping the cutouts 14, 14a, 14b in a suitable manner, practically any web shape can be used and form graded cross-sectional shapes. For example, more than two differently weaker secondary connecting webs or different cross-sectional shapes of individual connecting webs can also be generated.
