Description

Garantieversschlußkappe aus Kunststoff Guarantee cap made of plastic
Die Erfindung betrifft eine Verschlusskappe aus Kunststoff gemäss dem Oberbegriff von Anspruch 1.The invention relates to a plastic closure cap according to the preamble of claim 1.
Zum Anzeigen der Unversehrtheit von mit einem Verschluss verschlossenen Behältern werden häufig mechanische Garan¬ tiebänder verwendet. Diese Garantiebänder sind mittels Soll¬ bruchstellen am unteren Rand einer Verschlusskappe angebracht und wirken mit Rückhaltemitteln auf der Aussenseite eines Behälters zusammen. Wenn der Verschluss das erste Mal vom Behälter abgeschraubt wird, reissen diese Sollbruchstellen und das Garantieband wird zumindest teilweise von der Ver¬ schlusskappe getrennt. Ein abgetrenntes Garantieband zeigt an, dass der Behälter bereits geöffnet wurde. Bei nicht mehrfach verwendbaren Behältern werden meist Verschlusskappen mit einem Garantieband verwendet, welches nach dem Oeffnen vollständig von der Kappe getrennt wird und auf dem Behäl¬ terhals verbleibt. Die Verwendung solcher Garantiebänder ist bei wiederbefüllbaren Mehrwegflaschen nicht möglich. Bei solchen Behältern muss darauf geachtet werden, dass das Garantieband mit dem Entfernen der Verschlusskappe ebenfalls entfernt wird. Aus diesem Grund sind Garantiebänder von Verschlusskappen, welche bei Mehrwegbehältern verwendet werden, vorzugsweise an einer Stelle fest mit der Verschluss¬ kappe verbunden.Mechanical guarantee tapes are often used to indicate the integrity of containers closed with a closure. These guarantee tapes are attached to the lower edge of a closure cap by means of predetermined breaking points and interact with retaining means on the outside of a container. When the closure is unscrewed from the container for the first time, these predetermined breaking points tear and the guarantee band is at least partially separated from the closure cap. A separate guarantee band shows that the container has already been opened. In the case of containers which cannot be used repeatedly, closure caps with a guarantee band are used, which is completely separated from the cap after opening and remains on the neck of the container. The use of such guarantee tapes is not possible with refillable reusable bottles. With such containers, care must be taken to ensure that the guarantee tape is also removed when the cap is removed. For this reason, guarantee bands of closure caps, which are used in reusable containers, are preferably firmly connected to the closure cap at one point.
Ein Nachteil von solchen bekannten Anordnungen besteht darin, dass die an einer Stelle mit der Kappenwand verbundenen Garantiebänder nicht mehr am Flaschenhals anliegen, sondern nach aussen abstehen, wenn sie nicht mehr vollständig mit der Verschlusskappe verbunden sind. Diese abstehenden Garantie¬ bänder sind vor allem beim Wasch- und Wiederfüllvorgang von Mehrwegbehältern nachteilig. Beim Zurückgeben dieser Behälter werden die Verschlusskappen auf den Behälter aufgesetzt. Wenn die Behälter maschinell weiterbearbeitet werden, besteht die Gefahr, dass nebeneinanderstehende Behälter sich mit den hervorstehenden Garantiebändern ineinander verhaken. Da die Garantiebänder eine relativ hohe Festigkeit aufweisen müssen, damit sie beim erstmaligen Entfernen des Verschlusses zuver¬ lässig zerreissen und nicht aufweiten, können sich die über die Garantiebänder verhakten Behälter nicht voneinander lösen. Die Folge davon ist, dass die verhakten Behälter umfallen und eine Störung der Verarbeitungsanlage oder der Förderbänder verursachen.A disadvantage of such known arrangements is that the guarantee bands connected at one point to the cap wall no longer lie against the bottle neck, but protrude outwards when they are no longer completely connected to the closure cap. These protruding bands are particularly disadvantageous in the washing and refilling process of reusable containers. When returning these containers, the caps are placed on the container. If the containers are machined further, there is Danger of containers standing side by side interlocking with the protruding guarantee bands. Since the guarantee tapes must have a relatively high strength so that they reliably tear and do not expand when the closure is removed for the first time, the containers hooked on the guarantee tapes cannot detach from one another. The result is that the hooked containers fall over and cause a malfunction of the processing system or the conveyor belts.
Aufgabe der Erfindung ist es, die Nachteile des Bekannten zu vermeiden, insbesondere eine Verschlusskappe zum Verschlies- sen eines wiederbefüllbaren Behälters zu schaffen, die das Verhaken von abstehenden Garantiebändern zweier miteinander aneinanderstehender Behälter zuverlässig vermeidet.The object of the invention is to avoid the disadvantages of the known, in particular to create a closure cap for closing a refillable container, which reliably avoids the jamming of protruding guarantee tapes of two containers standing next to one another.
Erfindungsgemäss werden diese Aufgaben mit einer Verschluss¬ kappe mit den Merkmalen des kennzeichnenden Teils von Patent¬ anspruch 1 gelöst.According to the invention, these objects are achieved with a closure cap with the features of the characterizing part of patent claim 1.
Eine Verschlusskappe aus Kunststoff zum Verschliessen eines Behälters besteht im wesentlichen aus einem Kappenboden und einer am äusseren Rand des Kappenbodens befestigten Kappen¬ wand. Die Kappenwand weist auf ihrer Innenseite Rückhalteele¬ mente, beispielsweise ein Schraubgewinde auf, mit welchen die Verschlusskappe auf dem Hals eines Behälters, beispielsweise einer Getränkeflasche befestigt werden kann. Zur Anzeige der Unversehrtheit des verschlossenen Behälters weist die Ver¬ schlusskappe ausserdem ein am unteren Rand der Kappenwand angebrachtes Garantieband auf. Das Garantieband weist auf seiner einen Innenseite Rückhalteelemente auf, welche bei aufgesetzter Verschlusskappe mit Rückhaltemitteln auf der Aussenseite der Behältermündung zusammenwirken. Das Garan¬ tieband ist zumindest teilweise mit Sollbruchstellen mit dem unteren Rand der Kappenwand verbunden. Damit das Garantieband beim Entfernen des Verschlusses nicht auf der Behältermündung verbleibt, ist es an wenigstens einer Anwachsstelle fest mit der Kappenwand verbunden.A plastic closure cap for closing a container essentially consists of a cap base and a cap wall attached to the outer edge of the cap base. The inside of the cap wall has retaining elements, for example a screw thread, with which the closure cap can be attached to the neck of a container, for example a beverage bottle. To indicate the integrity of the closed container, the closure cap also has a guarantee band attached to the lower edge of the cap wall. The inside of the guarantee band has retaining elements which, when the closure cap is attached, interact with retaining means on the outside of the container mouth. The guarantee band is at least partially connected to predetermined breaking points with the lower edge of the cap wall. So that the guarantee band does not remain on the container mouth when the closure is removed, it is firmly attached to at least one growth point connected to the cap wall.
Das erfindungsgemässe Garantieband weist wenigstens zwei, etwa parallel zur Achse des Verschlusses angeordnete Gelenke auf. Dank dieser Gelenke ist das Garantieband als Ganzes weniger elastisch und es wird in mehrere kurze, in sich elastische und gegeneinander einfach bewegbare Einzelsegmente unterteilt. Beim erstmaligen Oeffnen des Verschlusses wird das Garantieband teilweise von der Kappenwand getrennt. Nebeneinanderstehende Behälter mit Verschlusskappen mit nach aussen stehenden Garantiebändern können sich aber mit einer solchen Konstruktion nicht mehr ineinander verhaken. Dank der Gelenke sind die Garantiebänder so beweglich ausgebildet, dass sich die Flaschen einfach wieder voneinander lösen.The guarantee band according to the invention has at least two joints arranged approximately parallel to the axis of the closure. Thanks to these joints, the guarantee band as a whole is less elastic and it is divided into several short, self-elastic individual segments that are easy to move against each other. When the closure is opened for the first time, the guarantee band is partially separated from the cap wall. Juxtaposed containers with caps with outward-facing guarantee bands can no longer get caught in one another with such a construction. Thanks to the joints, the guarantee bands are designed to be so flexible that the bottles can easily be detached from one another.
Das Garantieband weist wenigstens zwei, vorteilhaft drei Gelenke auf, die etwa in gleichmässigen Abständen über den Umfang des Garantiebandes verteilt sind. Ein besonders ein¬ faches Konstruktionsprinzip ergibt sich, wenn die Gelenke als Materialschwächungen im Garantieband ausgebildet sind. Diese Materialschwächungen können an sich sowohl auf der Innenseite als auch auf der Aussenseite des Bandes angebracht sein. Eine Anordnung auf der Aussenseite fördert die Flexibilität beson¬ ders. Eine Materialschwächung innen und aussen führt zu besonders flexiblen Garantiebändern.The guarantee band has at least two, advantageously three joints, which are distributed approximately at regular intervals over the circumference of the guarantee band. A particularly simple construction principle results if the joints are designed as material weaknesses in the guarantee band. These material weakenings can be applied both on the inside and on the outside of the band. An arrangement on the outside promotes flexibility in particular. A weakening of material on the inside and outside leads to particularly flexible guarantee bands.
Vorzugsweise werden als Rückhalteelemente auf der Innenseite des Garantiebandes umklappbare Widerhaken verwendet. Beson¬ ders günstig ist die Verwendung von mehreren Widerhaken, welche untereinander verbunden sind. In diesem Fall ist es vorteilhaft, die Gelenke zwischen zwei Widerhaken anzuordnen und diese Widerhaken nicht miteinander zu verbinden. Auf diese Weise wird die Flexibilität des Garantiebandes zusätz¬ lich erhöht.Foldable barbs are preferably used as retaining elements on the inside of the guarantee band. The use of a plurality of barbs which are connected to one another is particularly favorable. In this case it is advantageous to arrange the joints between two barbs and not to connect these barbs together. In this way, the flexibility of the guarantee band is additionally increased.
Damit das Garantieband und die Verschlusskappe beim erst¬ maligen Oeffnen nicht vollständig voneinander getrennt wer- den, ist das Garantieband in einer Anwachsstelle fest mit der Kappenwand verbunden. Gleich benachbart zu dieser Anwachs¬ stelle ist auf der einen Seite eine vertikale Sollbruchlinie angeordnet, die das Aufreissen des Garantiebandes beim erst¬ maligen Entfernen der Verschlusskappe vom Behälter ermög¬ licht. In einem besonders bevorzugten Ausführungsbeispiel ist ein Gelenk benachbart zur anderen Seite der Anwachsstelle angeordnet.So that the guarantee band and the closure cap are not completely separated from one another when it is opened for the first time the, the guarantee tape is firmly attached to the cap wall in a growth point. A vertical predetermined breaking line is arranged on one side immediately adjacent to this growth point, which enables the tamper-evident band to be torn open when the closure cap is removed from the container for the first time. In a particularly preferred embodiment, a joint is arranged adjacent to the other side of the growth site.
Die Erfindung wird nachfolgend in Ausführungsbeispielen und anhand der Zeichnungen näher erläutert. Es zeigen:The invention is explained in more detail below in exemplary embodiments and with reference to the drawings. Show it:

Figur 1 zeigt die Unteransicht einer Verschlusskappe 1, welche aus einem Boden 2 und einer, am äusseren Rand des Bodens 2 befestigten Kappenwand 4 besteht. Am unteren Rand der Kappenwand 4 ist ein Garantieband 8 angebracht. Das Garantieband 8 ist teilweise lösbar mit Sollbruchstegen 14 und teilweise fest mit einer Anwachsstelle 13 mit der Kappen¬ wand 4 verbunden. Das Garantieband weist vier Gelenke 9 auf. Die Gelenke 9 sind als Materialverdünnung auf der Aussenseite des Garantiebandes ausgebildet. Sie verteilen sich auf dem Umfang des Garantiebandes 8. Ein Gelenk 9 ist benachbart zu der Anwachsstelle 13 angeordnet. Auf der anderen Seite der Anwachsstelle 13 ist eine vertikale Sollbruchlinie 15 vor¬ gesehen. Beim erstmaligen Oeffnen des Verschlusses 1 zer- reisst das Garantieband 8 im Bereich der Sollbruchline 15 und löst sich an den Sollbruchstegen 14 von der Kappenwand 4. Das Garantieband 8 bleibt jedoch an der Anwachsstelle 13 mit der Kappenwand 4 verbunden. Dank der Gelenke 9 weist aber das nun von der Verschlusskappe gelöste Garantieband eine grosse Beweglichkeit auf.FIG. 1 shows the bottom view of a closure cap 1, which consists of a base 2 and a cap wall 4 fastened to the outer edge of the base 2. At the lower edge of the cap wall 4, a guarantee band 8 is attached. The guarantee band 8 is partly detachably connected to predetermined breaking bars 14 and partly fixedly to an enlargement point 13 with the cap wall 4. The guarantee band has four joints 9. The joints 9 are designed as a thinner material on the outside of the guarantee band. They are distributed over the circumference of the guarantee band 8. A joint 9 is arranged adjacent to the growth point 13. On the other side of the A vertical predetermined breaking line 15 is provided at the growth point 13. When the closure 1 is opened for the first time, the guarantee band 8 tears in the area of the predetermined breaking line 15 and detaches from the cap wall 4 at the predetermined breaking webs 14. However, the guarantee band 8 remains connected to the cap wall 4 at the growth point 13. Thanks to the joints 9, however, the guarantee band now detached from the closure cap has great mobility.
Figur 2 zeigt einen Querschnitt durch eine erfindungsgemässe Verschlusskappe 1. Auf der Innenseite der Kappenwand 4 sind Rückhaltemittel 5 vorgesehen, mittels welcher die Verschluss¬ kappe 1 auf einem Behälter befestigt werden kann. Das am unteren Rand der Kappenwand 4 angebrachte Garantieband 8 weist auf seiner Innenseite Rückhaltemittel 16 auf, welche mit Rückhalteelementen auf der Aussenseite des Behälters zusammenwirken. Das Garantieband ist mittels Sollbruchstegen 14 lösbar und mittels einer Anwachsstelle 13 fest mit der Kappenwand 4 verbunden. Benachbart zu der Anwachsstelle 13 liegen auf der einen Seite eine vertikale Sollbruchlinie 15 und auf der anderen Seite ein Gelenk 9. Zur Erhöhung der Flexibilität können die Rückhaltemittel 16 im Bereich des Gelenkes 9 ausserdem eine Unterbrechung 17 aufweisen.FIG. 2 shows a cross section through a closure cap 1 according to the invention. Retaining means 5 are provided on the inside of the cap wall 4, by means of which the closure cap 1 can be attached to a container. The guarantee band 8 attached to the lower edge of the cap wall 4 has retaining means 16 on its inside, which cooperate with retaining elements on the outside of the container. The guarantee band can be detached by means of predetermined breaking bars 14 and is firmly connected to the cap wall 4 by means of a growth point 13. Adjacent to the growth point 13 are a vertical predetermined breaking line 15 on one side and a joint 9 on the other side. To increase flexibility, the restraining means 16 can also have an interruption 17 in the region of the joint 9.
Figur 3 zeigt eine von einem Behälter abgeschraubte Ver¬ schlusskappe 1. Das Garantieband 8 ist im Bereich der Soll¬ bruchstege 14 von der Kappenwand 4 getrennt und ist mit dieser nur noch über die Anwachsstelle 13 verbunden. Gleich benachbart zur Anwachsstelle 13 befindet sich ein erstes Gelenk 9. Weitere Gelenke 9 verteilen sich gleichmässig über den Umfang des Garantiebandes 8. Das Garantieband wird da¬ durch in fünf einzelne Segmente unterteilt, welche gegenein¬ ander relativ frei beweglich sind.FIG. 3 shows a closure cap 1 unscrewed from a container. The guarantee band 8 is separated from the cap wall 4 in the region of the predetermined breaking webs 14 and is only connected to it via the growth point 13. A first joint 9 is located directly adjacent to the growth point 13. Further joints 9 are distributed uniformly over the circumference of the guarantee band 8. The guarantee band is thereby divided into five individual segments which are relatively freely movable with respect to one another.
Wie in Figur 4 gezeigt, kann das Gelenk 9 durch eine Mate¬ rialvertiefung 10 auf der Aussenseite des Garantiebandes gebildet werden. Auf der Innenseite verläuft dabei ein durch- gehendes Rückhalteelement. In dem Ausführungsbeispiel gemäss Figur 5 wird das Gelenk 9 durch eine auf der Innenseite des Garantiebandes 8 liegende Vertiefung ausgebildet. Zur Erhö¬ hung der Flexibilität weisen die Rückhaltemittel 16 im Be¬ reich des Gelenkes 9 eine Unterbrechung 17 auf.As shown in FIG. 4, the joint 9 can be formed by a material recess 10 on the outside of the guarantee band. There is a continuous walking retention element. In the exemplary embodiment according to FIG. 5, the joint 9 is formed by a recess lying on the inside of the guarantee band 8. In order to increase flexibility, the restraining means 16 have an interruption 17 in the area of the joint 9.
Wenn die Rückhaltemittel 16 wie in Figur 6 aus einzelnen Widerhaken bestehen, empfiehlt es sich, die Gelenke 9 jeweils zwischen zwei nebeneinanderliegende Widerhaken anzuordnen. Vorzugsweise sind die Widerhaken miteinander verbunden und nur gerade im Bereich der Gelenke 9 jeweils mit einer Unter¬ brechung 17 versehen. If the restraining means 16 consist of individual barbs, as in FIG. 6, it is advisable to arrange the joints 9 in each case between two adjacent barbs. The barbs are preferably connected to one another and provided with an interruption 17 only in the area of the joints 9.
