Die Figuren 1 bis 4 zeigen einen Stopfen 1 mit einem Garan¬ tieband 6, aufgesetzt auf eine zylindrische Wand 2 eines BehältersX Dieser Behälter "kann ein Röhrchen aus Metall, beispielsweise Aluminium, oder aus Kunststoff sein, bei¬ spielsweise Polypropylen, Polystyrol oder Poly- ethylenterephthalat (PET).Elements with the same reference numerals. FIGS. 1 to 4 show a stopper 1 with a guarantee band 6, placed on a cylindrical wall 2 of a container X. This container " can be a tube made of metal, for example aluminum, or of plastic, for example polypropylene, polystyrene or poly ethylene terephthalate (PET).
Der Teil der Wand 2 ist in der Nähe des Randes mit einem durchgehenden kreisförmigen Aussenwulst 3 ver- sehen, welcher im axialen Schnitt beispielsweise die Form eines Hackens haben kann.The part of the wall 2 is provided near the edge with a continuous circular outer bead 3, which can have the shape of a hook, for example, in the axial section.
Der Stopfen 1 umfasst einen Teil des Deckels 4, dessen äusserer Durchmesser grösser ist als der grösste Durchmesser des Teiles der Wand 2 des Behälters. Der Deckel 4 hat an seiner Peripherie einen ringförmigen Teil 5, welcher den Rand der Wand 2 des Behälters um¬ gibt.The stopper 1 comprises a part of the lid 4, the outer diameter of which is larger than the largest diameter of the part of the wall 2 of the container. The lid 4 has on its periphery an annular part 5 which surrounds the edge of the wall 2 of the container.
Ein Garantieband 6 ist in der Verlängerung des ringförmigen Teiles 5 angeordnet und ist auf seiner In- nenseite mit einer Rückhaltevorrichtung 7 versehen, bei¬ spielsweise eine bestimmte Anzahl von Laschen. Diese La¬ schen sind derart ausgebildet und plaziert sowie auf den Aussenwulst 3 abgestimmt, dass die Entfernung des Stop¬ fens verhindert wird, solange der ringförmige Teil 5 mit dem Garantieband 6 vereint ist. Der erfindungsgemässe Stopfen wird vorzugs¬ weise gemäss dem erfindungsgemässen Verfahren herge¬ stellt.A guarantee band 6 is arranged in the extension of the annular part 5 and is provided on the inside with a retaining device 7, for example a certain number of tabs. These tabs are designed and placed in such a way and matched to the outer bead 3 that the removal of the stopper is prevented as long as the annular part 5 is combined with the guarantee band 6. The stopper according to the invention is preferably produced according to the method according to the invention.
Der Deckel 4 kann auch eine im wesentlichen zylindrische Wand 8 und ein zylindrisches Abteil 9, wel¬ ches zur Aufnahme eines Trocknungsmittels 10 bestimmt ist, umfassen.The cover 4 can also comprise an essentially cylindrical wall 8 and a cylindrical compartment 9, which is intended to hold a drying agent 10.
Ein solcher Deckel kann leicht aus dem ent¬ sprechenden Spritzwerkzeug herausgenommen werden.Such a cover can be easily removed from the corresponding injection mold.
Desgleichen wird das Garantieband 6 durch In¬ jektion in ein Spritzwerkzeug erhalten. Aus diesem Spritzwerkzeug kann es dank seiner Form ohne Schwierig¬ keiten herausgenommen werden.Likewise, the guarantee tape 6 is obtained by injection into an injection mold. Thanks to its shape, it can be removed from this injection mold without difficulty.
Der oben beschriebene Teil des Deckels und das Garantieband 6 werden anschliessend miteinander derart verbunden, dass sie mittels externer Krafteinwirkung auf den oberen Rand des Stopfens 1 voneinander getrennt wer¬ den können.The part of the cover described above and the guarantee band 6 are then connected to one another in such a way that they can be separated from one another by means of external forces acting on the upper edge of the stopper 1.
Für diesen Zweck können der genannte Teil des Deckels 4 mit dem ringförmigen Teil 5 und das Garantie¬ band 6 aneinander angrenzende und aufeinander abge¬ stimmte Ränder haben, wobei diese Ränder stufenförmig angeordnet oder schräg sein können.For this purpose, said part of the cover 4 with the ring-shaped part 5 and the guarantee band 6 can have mutually adjoining and coordinated edges, these edges being arranged in steps or obliquely.
Diese Ausbildung dieser Ränder sind aus den Figuren 2 und 4 gut ersichtlich.This formation of these edges can be seen clearly from FIGS. 2 and 4.
Diese Ränder werden anschliessend miteinander mittels punktweiser oder durchgehender Verschweissung oder mittels Verklebung miteinander verbunden, und zwar derart, dass sie wieder voneinander getrennt werden kön¬ nen, wie dies in Figur 5 illustriert ist.These edges are then connected to one another by means of point-by-point or continuous welding or by means of gluing, to be precise such that they can be separated from one another again, as is illustrated in FIG. 5.
Das Garantieband 6 wird durch den Aussenwulst 3 des Behälters zurückgehalten und kann nur in entgegen- gesetzter Richtung zur Entfernung des Deckelteiles weg¬ genommen werden, wie dies in Figur 6 illustriert ist.The guarantee band 6 is retained by the outer bead 3 of the container and can only be removed in the opposite direction to remove the cover part, as is illustrated in FIG. 6.
Es sei festgehalten, dass der genannte Teil des Deckels 4 mit"dem ringförmigen Teil 5" und" das Garan¬ tieband 6, falls dies gewünscht ist, aus dem gleichen oder aus verschiedenen Kunststoff(en) hergestellt sein können. Diese Teile können auch aus dem gleichen Kunst¬ stofftyp hergestellt sein, aber verschiedene Farben auf¬ weisen.It should be noted that the named part of the cover 4 with " the annular part 5 " and " the guarantee band 6, if desired, can be made of the same or different plastic (s). These parts can also be made of be made of the same type of plastic, but have different colors.
Die Trennung des komplexen Stückes, wie dies die Gesamtheit des Stopfens 1 mit Garantieband 6 dar¬ stellt, erlaubt so die Verwendung von Spritzwerkzeugen, die wesentlich günstiger sind, ebenso im Hinblick auf ihre Fabrikationskosten und ihren Unterhalt, im Ver¬ gleich zu den notwendigen Spritzwerkzeugen für die Her- Stellung eines solchen Stopfens aus einem einzigen Stuck.The separation of the complex piece, as represented by the whole of the stopper 1 with the guarantee band 6, thus allows the use of injection molds which are considerably cheaper, also in terms of their manufacturing costs and their maintenance, in comparison to the necessary injection molds for the production of such a stopper from a single piece.
Ein weiterer wesentlicher Vorteil des erfin- dungsgemässen Stopfens besteht in der Möglichkeit, das Garantieband 6 vom genannten Teil des Deckels 4 mit dem ringförmigen Teil 5 durch eine andere Farbe hervorzuhe¬ ben.Another essential advantage of the stopper according to the invention is the possibility of highlighting the guarantee band 6 from the named part of the cover 4 with the annular part 5 by a different color.
Es sei festgehalten, dass die Vereinigung des genannten ringförmigen Teiles 5 mit dem Garantieband 6 im gleichen Arbeitsablauf und in der gleichen Vorrich- tung erfolgen kann, in der das Abteil 9 mit einem Trock¬ nungsmittel 10, beispielsweise Silicagel, gefüllt wird.It should be noted that the union of the annular part 5 mentioned with the guarantee band 6 in the same workflow and in the same device. can take place in which the compartment 9 is filled with a drying agent 10, for example silica gel.
Die Reihenfolge dieser Schritte ist nicht wichtig.The order of these steps is not important.

Teil 5 in gegenseitig abgestimmte Position gebracht wor¬ den sind, dann werden diese Teile mittels Verschweissung oder mittels VerkleBüng miteinander in trennbäJrer Form verbunden.Part 5 have been brought into mutually coordinated position, then these parts are connected to one another in a separable form by means of welding or by means of adhesive bonding.
Die Verschweissung kann kontinuierlich oder vorzugsweise mittels einzelnen isolierten Punkten erfol¬ gen.The welding can be carried out continuously or preferably by means of individual isolated points.
Die Verschweissung kann eine thermische Ver¬ schweissung, eine Ultraschall-Verschweissung oder eine Laser-Verschweissung sein.The welding can be a thermal welding, an ultrasound welding or a laser welding.
Die mechanische Widerstandskraft der beiden so verbundenen Teile ist derart, dass dieser Verbund hält, wenn man den Stopfen 1 über den Aussenwulst 3 hinweg auf den Behälter aufsetzt, und dass dieser Verbund beim er- sten Oeffnen leicht zerstört wird.The mechanical resistance of the two parts connected in this way is such that this assembly holds when the stopper 1 is placed over the outer bead 3 on the container, and that this assembly is easily destroyed the first time it is opened.
Es ist auch möglich, andere Kunststoffe für die Herstellung des erfindungsgemässen Stopfens 1 zu verwenden, beispielsweise Polypropylen oder EPDM. It is also possible to use other plastics for the production of the stopper 1 according to the invention, for example polypropylene or EPDM.
