Description

Die vorliegende Erfindung betrifft einen Stopfen für einen Behälter und ein Verfahren zur Herstellung dieses Stopfens.The present invention relates to a stopper for a container and a method of manufacture this stuffing.

Stopfen mit oder ohne Garantieband, welche im Stand der Technik bekannt sind, sind in den Figuren 1 bis 3 gezeigt.Stopper with or without guarantee band, which in the 1 are known in the prior art shown to 3.

Die Figuren 1 bis 3 zeigen Seitenansichten, welche teilweise axial aufgeschnitten sind, von im Stand der Technik bekannten Stopfen.Figures 1 to 3 show side views, which are partially cut open axially from the stand stopper known in the art.

In Figur 1 ist ein Stopfen mit Garantieband 54 der ersten Generation gezeigt.FIG. 1 shows a stopper with a guarantee band 54 of the first generation.

Bei diesem Stopfen hat der Deckel 50 die Funktion eines Trägers für vier Teile, nämlich die Kammerwand 51, die Druckfeder 52, die Olive 53 und das Garantieband 54.The cover 50 has the function of this stopper a carrier for four parts, namely the chamber wall 51, the compression spring 52, the olive 53 and the guarantee tape 54.

Wenn dieser Stopfen zum Verschliessen eines Röhrchens mit einem Innendurchmesser von 27 mm vorgesehen ist und die Kammer zur Aufnahme des Trockenmittels 56 ein Volumen von 2,56 cm3 hat, dann wiegt dieser Stopfen, ohne Karton 55 und ohne Trockenmittel 56, 5,5 g.If this stopper is provided for closing a tube with an inner diameter of 27 mm and the chamber for receiving the drying agent 56 has a volume of 2.56 cm 3 , then this stopper, without box 55 and without drying agent 56, weighs 5.5 g .

Die Teile 51 bis 54 sind alle nebeneinander und in bestimmten Abständen zueinander angeordnet.The parts 51 to 54 are all next to each other and arranged at certain distances from each other.

Ein solcher Stopfen kann nur in einem sehr komplizierten Spritzwerkzeug hergestellt werden. Die Entformung erfolgt zwangsmässig in 5 Etappen, wodurch die Zykluszeit signifikant verlängert wird.Such a stopper can only be used in one complicated injection mold. The Demolding takes place in 5 stages, which means that the cycle time is significantly extended.

In Figur 2 ist ein Stopfen mit Garantieband 60 gezeigt, bei welchem die Druckfeder 61 in der Verlängerung der Olive 62 positioniert ist.FIG. 2 shows a stopper with a guarantee band 60 shown, in which the compression spring 61 in the extension the olive 62 is positioned.

Im Vergleich zum in Figur 1 gezeigten Stopfen ist der Deckel 64 nur noch Träger von drei Teilen.In comparison to the stopper shown in Figure 1 the cover 64 is only a carrier of three parts.

Dieser Stopfen hat für die gleiche weiter oben beschriebene Anwendung ein Gewicht von 5,0 g und ist im Vergleich zum in Figur 1 gezeigten Stopfen einfacher und schneller herzustellen. Die Entformung kann in 4 Etappen erfolgen.This plug has the same for the same one above described application has a weight of 5.0 g and is in Comparison simpler and to the plug shown in Figure 1 manufacture faster. The demoulding can be done in 4 stages respectively.

Weil die Druckfeder 61 in der Verlängerung der Olive 62 positioniert ist, bleibt zwischen dem Aussenmass der Druckfeder 61 und dem Innendurchmesser der Behälteröffnung sehr wenig Spielraum.Because the compression spring 61 in the extension of the Olive 62 is positioned, remains between the outer dimensions the compression spring 61 and the inner diameter of the container opening very little scope.

Deshalb muss dieser Stopfen sehr präzise in die Behälteröffnung eingeführt werden ansonsten die Druckfeder 61 beschädigt wird.Therefore this plug must be very precise otherwise the container opening will be inserted Compression spring 61 is damaged.

In Figur 3 ist ein Stopfen mit Garantieband 70 gezeigt. Dieser Stopfen hat einen Leerraum 71. Bedingt durch diesen Leerraum 71 wird ein Teil 72 des Deckels nach unten verschoben. Dies erlaubt, das Aussenmass der Druckfeder 73, im Vergleich zum in Figur 2 gezeigten Stopfen, zu reduzieren und gleichzeitig den Vorteil der Entformung in 4 Etappen beizubehalten. FIG. 3 shows a stopper with a guarantee band 70 shown. This plug has an empty space 71. Conditional through this empty space 71 becomes part 72 of the cover shifted down. This allows the outside dimensions of the Compression spring 73, compared to that shown in Figure 2 Darning, reduce while taking advantage of To keep demoulding in 4 stages.

Dieser Stopfen hat wiederum für die gleiche weiter oben beschriebene Anwendung ein Gewicht von nur noch 3,5 g.This plug in turn has the same application described above has a weight of only 3.5 g more.

Im Leerraum 71 können sich unerwünschte Stoffe, wie etwa Staub, ansammeln.Unwanted can occur in the empty space 71 Collect substances such as dust.

Um das übliche Volumen von etwa 2,6 cm3 der Kammer 74 beizubehalten, ist es wegen dem kleineren Durchmesser der Kammer 74 notwendig, die Höhe dieser Kammer 74 entsprechend um die Distanz d zu vergrössern.In order to maintain the usual volume of approximately 2.6 cm 3 of the chamber 74, it is necessary because of the smaller diameter of the chamber 74 to increase the height of this chamber 74 by the distance d.

Als Folge davon wird die aktive Zone der Druckfeder 73 entsprechend reduziert.As a result, the active zone of the Compression spring 73 reduced accordingly.

Bei den in den Figuren 1 bis 3 gezeigten Stopfen muss das Trockenmittel aus der Richtung der jeweiligen Druckfeder her, also von unten her, eingeführt werden.In the plugs shown in Figures 1 to 3 the desiccant must be from the direction of each Compression spring introduced, i.e. from below become.

Anschliessend muss aus der gleichen Richtung her eine Kartonscheibe 55, 65, 75 eingeführt und mittels Umbördelung fixiert werden.Then it must come from the same direction forth a cardboard disc 55, 65, 75 inserted and by means of Flanging can be fixed.

Bei allen oben beschriebenen Stopfen wird das Trocknenmittel 56, 66, 76 in einem separaten Schritt eingeführt.With all the plugs described above, this will Drying agents 56, 66, 76 in a separate step introduced.

Die Spritzwerkzeuge zur Herstellung dieser Stopfen sind sehr kompliziert, teuer bei der Anschaffung und teuer beim Unterhalt.The injection molds for making this Plugs are very complicated, expensive to buy and expensive to maintain.

Die oben beschriebenen Stopfen bestehen aus einem einzigen Stück. The plugs described above consist of one piece.

Das Spritzgiessen eines einzigen Stückes impliziert auch, dass alle Teile aus dem gleichen Kunststoff hergestellt sind und die gleiche Farbe haben.The injection molding of a single piece implies also that all parts are made of the same plastic are made and have the same color.
