Description

Behälterverschluß mit Garantiering aus thermoplastischem Material Es sind am Markt Verschlüsse bekannt, meist aus Aluminium die becherförmig über Behältermündungen gestülpt werden und dann durch rotierende Rollen, die unter Federdruck stehen, an die Behältermündung angeformt werden. Es sind dies die sogenannten Pilferproof-Verschlüsse.Container closure with a guarantee ring made of thermoplastic material There are closures known on the market, mostly made of aluminum, which are placed in the shape of a cup over container mouths and then molded onto the container mouth by rotating rollers that are under spring pressure . These are the so-called pilferproof closures.

Diese Verschlüsse haben den Nachteil des billigen Aus- sehens. Auf der anderen Seite dringt der Kunststoff vor allem das thermoplastische Material immer mehr auf dem Verschlußsektor vor. Vor allen Dingen auf dem pharma- zeutisch- und kosmetischen Sektor werden die Forderungen auf Garantie erhoben, jedoch unter gleichzeitigem Anspruch auf wertvolle äußere Gestaltung, Die Schwierigkeit der Aufgabe war, daß zu dem normalen Druckverformen bei Metall der Plastifizierungsvorgang durch Wärme hinzukommen muss bei gleichzeitiger Anfor- derung hoher Geschwindigkeiten bzw, hoher Ausstoßzeiten, Vorliegende Erfindung hat dieses Problem dadurch gelöst daß die Andruckrollen mit einem abgestimmten Grammgewicht an das noch kalte, zu verformende Teil andrücken, das in dem Augenblick, in dem der therzoplastische Aggregatzustand erreicht ist, fast verzögerungslos die Anforoung einsetzt. Grundsätzlich ist ausser dem bisherigen Verfahren durch bloße Druckverformung die Anforaung zu erzielen durch das Hinzubringen von Wärme* wobei sowohl Heißluft aus Düsen mit hoher Geschwindigkeit austritt als auch Rollen ih hoher Geschwindigkeit Reibungswärme erzeugen können. Da es auf den als Erfindungshöhe vorrangig hervorgestelltih n Effekt der verzögerungslosen Abtastung des thermoplaetischen Aggregatzustandes ankommt, zeigt der Umstand, daß bei einein@ Material, dessen Formbeständigkeit bei etwa $0 - 90 Grad liegt, die Düsentemperatur 200 - 250 Grad aufweist, das einer Temperatur entspricht bei der normalerweise die. Zersetzung des Materials beginnt. Der Plastifizierungsprozess setzt also schlagartig ein. Diesem schlagartigen Einsetzen muß die Be- reitschaft der Druckrollen schlagartig erfolgen. These closures have the disadvantage of being cheap in appearance. On the other hand, the plastic, especially the thermoplastic material, is increasingly penetrating the closure sector. Above all in the pharmaceutical and cosmetic sector, the demands for a guarantee are raised, but at the same time with a claim to valuable external design. The difficulty of the task was that the plasticizing process by heat must be added to the normal pressure deformation of metal with simultaneous request - Change of high speeds or high ejection times, the present invention has solved this problem in that the pressure rollers press with a coordinated gram weight on the still cold part to be deformed, which at the moment the thermoplastic aggregate state is reached, the request is almost instantaneous begins. Basically, apart from the previous method, the shaping can be achieved by simple compression deformation by adding heat * whereby both hot air exits nozzles at high speed and rollers at high speed can generate frictional heat . Since it depends on the effect of the instantaneous scanning of the thermoplastic state of aggregation , which is primarily emphasized as the level of invention , the fact shows that with a material, whose dimensional stability is around $ 0-90 degrees , the nozzle temperature is 200-250 degrees, which corresponds to one temperature where normally the. The material starts to decompose. The plasticization process starts suddenly. The readiness of the pressure rollers must take place suddenly for this sudden onset.

In den beigefügten Zeichnungen ist dieser Vorgang in den Abbe I bis XI im Prinzip dargestellt. Abb. I zeigt, daß zuerst die Rolle unter leichtem Druck sich an den Garantiering bzw. an die jeweils zu verformende Fläche des Verschlusses anlegt. Der Verschluss ist hierbei noch in normalen Temperaturzu- stand. In the accompanying drawings, this process is shown in principle in Figures I to XI. Fig. I shows that the roller first rests against the guarantee ring or the surface of the fastener to be deformed under slight pressure. The closure is still at normal temperature .

Abbe X veranschaulicht das Hinzukommen von Heißluft P. Abbe X illustrates the addition of hot air P.

Abb. XI zeigt den Endzustand nach der plastischen Verformung. Dabei verweilt die Rolle länger als die Düse im Bereich des Arbeitsvorganges, weil sie noch eine Abkühlfunktion auszu- führen hat, Abbe I - VIII veranschaulichen wie folgt die vorzugsweise Verfahrensweise an diversen Verschlüssen. Fig. XI shows the final state after plastic deformation. The roller stays longer than the nozzle in the area of the work process because it still has to perform a cooling function . Figures I - VIII illustrate the preferred procedure for various closures as follows.

Abbe I zeigt die vorgefertigte Schraubkappe'b'und den Garantieabreißring'a'.Abbe I shows the prefabricated screw cap'b 'and the warranty tear-off ring'a'.

IV auch das vewinde "f" thermoplastisch anjeformt wird in der selben Arbeitsweise wie der Garantiering.

Abt The locking part at the level of the deformation of the housing is in the blank in a smooth, cup-shaped design.

V zeigt einen Verschlußteil, das nur in Becherausführung als Vergleich vorgesehen ist und bei dem ausser der thermoplastischen Anformung von Garantiering und Gewinde auch gleichzeitig die Durchbruch-Stege für den Garantiering thermoplastisch angerollt werden.Abbot). V shows a closure part that is only available as a cup design Comparison is provided and in which, in addition to the thermoplastic molding of The guarantee ring and thread are also the breakthrough bars for the guarantee ring at the same time be rolled on thermoplastically.

Abb. VII und VIII wiederholen im hrinzip die Darstellungen V und VI, nur ist hier ein Schlauchabschnitt bzw. Rohrabschnitt vorgesehen zum Aufdrücken eines Mündungsstopfens oder auch einer herkömmlichen Schraubkappe.Figs. VII and VIII repeat the illustrations V and VI in principle, only a hose section or pipe section is provided here for pressing on a mouth plug or a conventional screw cap.

Als Material für das Verfahren kommen dem Wesen der Er-findung gemäß alle thermoplastischen Kunststoffe infrage. Es wird einen grossen Zukunftsbedarf am Markt ausfüllen und entspricht dem Rationalisierungseffekt der automatischen Verpackungsweise, Vor allen Dingen kann das Verfahren in einem Arbeitsgang sowohl in herkömmlicher Art das Auf-schrauben des Verschlusses vereinigen mit der gleichzeitigen Anformung des Garantieringes. According to the essence of the invention, all thermoplastic plastics come into consideration as material for the method. It will meet a great future demand on the market and corresponds to the rationalization effect of the automatic packaging method. Above all, the process can combine the screwing of the closure with the simultaneous molding of the guarantee ring in one operation in a conventional way.
