Description

Die Erfindung betrifft einen Universalflaschenverschluß nach dem Oberbegriff des Anspruches 1.The invention relates to a universal bottle stopper according to the preamble of claim 1.

Ein derartiger Flaschenverschluß ist aus der EP-A-355 795 bekannt. Bei diesem bekannten Flaschenverschluß sind die beiden Kappen ebenfalls getrennt hergestellt, sie sind so konstruiert und miteinander "verbunden", daß sich die eine Kappe in Bezug auf die andere Kappe um eine gemeinsame Achse drehen kann. Zum Dichten zumindest der Flasche kleineren Durchmessers ist eine Dichtlippe innen an der inneren Kappe vorgesehen, die an der Außenwand der Flasche kleineren Durchmesser zur Anlage gelangt.Such a bottle stopper is known from EP-A-355 795. In this known bottle stopper, the two caps are also manufactured separately, they are constructed and "connected" to one another so that one cap can rotate about a common axis with respect to the other cap. To seal at least the bottle of smaller diameter, a sealing lip is provided on the inside of the inner cap, which comes to rest on the outer wall of the bottle of smaller diameter.

Der Erfindung liegt nun die Aufgabe zugrunde, einen Universalflaschenverschluß der eingangs genannten Art zu schaffen, der bei einfacher und preiswerter Herstellung für einen dichten Verschluß der beiden Flaschen unterschiedlichen Durchmessers sorgt.The object of the invention is to create a universal bottle stopper of the type mentioned at the beginning which, with simple and inexpensive manufacture, ensures a tight closure of the two bottles of different diameters.

Diese Aufgabe wird durch das Kennzeichen des Anspruches 1 gelöst.This object is achieved by the characterizing part of claim 1.

Erfindungsgemäß ist die innere Kappe aus relativ weichem thermoplastischem Kunststoff hergestellt, so daß die beiden Dichtflansche die gewünschte Dichtwirkung im Verhältnis zu den entsprechenden Anlageflächen der beiden Flaschen unterschiedlichen Durchmessers sicherstellen. Die "Weichheit" der inneren Kappe ist so gewählt, daß einerseits die Verschlußwirkung, beispielsweise als Schnappverschluß, gewährleistet und andererseits für eine gute Dichtung durch Anlage des inneren Flansches gesorgt wird. Die äußere Kappe, die vorzugsweise als Überwurfmutter ausgebildet ist, drückt den ebenfalls entsprechend weichen, äußeren Flansch auf die zugeordnete Flasche größeren Durchmessers, wenn der Verschluß für eine solche Flasche eingesetzt wird.According to the invention, the inner cap is made of relatively soft thermoplastic, so that the two sealing flanges ensure the desired sealing effect in relation to the corresponding contact surfaces of the two bottles of different diameters. The "softness" of the inner cap is chosen so that, on the one hand, the locking effect, for example as a snap lock, is ensured and, on the other hand, a good seal is provided by the inner flange being in contact. The outer cap, which is preferably designed as a union nut, presses the correspondingly soft, outer flange onto the associated bottle of larger diameter when the closure is used for such a bottle.

In vorteilhafter Weise erfolgt die Verbindung der beiden Kappen aus Werkstoffen mit unterschiedlichen Eigenschaften durch einen Verbindungsring, mit dessen Hilfe die beiden Kappen miteinander verschweißt werden. Die Materialeigenschaften des Verbindungsringes entsprechen insbesondere hinsichtlich Weichheit denjenigen der inneren Kappe. (Anspruch 2).The two caps made of materials with different properties are advantageously connected by a connecting ring, by means of which the two caps are welded together. The material properties of the connecting ring correspond in particular to those of the inner cap with regard to softness. (Claim 2).

Wenn die Ausbildung so erfolgt, wie in den Ansprüchen 3 und 4 angegeben, dann wird die Weichheit der inneren Kappe ausgenutzt, um das Aufschnappen der inneren Kappe auf eine Flasche kleineren Durchmessers zu begünstigen. Das härtere Material der äußeren Kappe begünstigt die Befestigung mit Hilfe des Innengewindes.If the formation is as set out in claims 3 and 4, then the softness of the inner cap is exploited to favor snapping the inner cap onto a bottle of smaller diameter. The harder material of the outer cap favors attachment with the help of the internal thread.

Im folgenden wird die Erfindung unter Hinweis auf die Zeichnung anhand eines Ausführungsbeispieles näher erläutert.The invention is explained in more detail below with reference to the drawing using an exemplary embodiment.

Es zeigt:

Fig. 1
eine Seitenansicht einer Ausführungsform eines Universalflaschenverschlusses nach der Erfindung; und
Fig. 2
einen schnitt gemäß der Linie II-II der Fig. 1.
It shows:
Fig. 1
a side view of an embodiment of a universal bottle stopper according to the invention; and
Fig. 2
a section along the line II-II of FIG. 1st

Der in der Zeichnung dargestellte Universalflaschenverschluß besteht im wesentlichen aus zwei Teilen, nämlich einer äußeren Kappe 1 und einer inneren Kappe 2. Diese sind koaxial zueinander angeordnet. Die innere Kappe 2 läßt einen Innenraum zur Aufnahme einer Flasche kleineren Durchmessers frei. Zwischen den beiden Kappen befindet sich ein Ringraum 3, der der Aufnahme einer Flasche größeren Durchmessers dient.The universal bottle cap shown in the drawing consists essentially of two parts, namely an outer cap 1 and an inner cap 2. These are arranged coaxially to one another. The inner cap 2 leaves an interior for receiving a bottle of smaller diameter. Between the two caps there is an annular space 3, which serves to hold a bottle of larger diameter.

Die innere Kappe ist als Schnappverschluß ausgebildet. Zu diesem Zweck steht innen ein Ringwulst 6 vor, der in eine entsprechende Ringnut der Flasche eingreift.The inner cap is designed as a snap lock. For this purpose, an annular bead 6 protrudes on the inside, which engages in a corresponding annular groove in the bottle.

Die äußere Kappe 1 ist als Überwurfmutter mit Innengewinde 4 ausgebildet.The outer cap 1 is designed as a union nut with an internal thread 4.

Die innere Kappe 2 ist aus relativ weichem, thermoplastischem Kunststoff, beispielsweise PU, EVA oder weichem PVC hergestellt. Die äußere Kappe besteht ebenfalls aus einem thermoplastischem Kunststoff, der aber härter ist. Beispielsweise kann es sich um Polystyrol handeln.The inner cap 2 is made of relatively soft, thermoplastic material, for example PU, EVA or soft PVC. The outer cap is also made of a thermoplastic, which is harder. For example, it can be polystyrene.

Die beiden Kappen sind dauerhaft miteinander verbunden. Dieses geschieht mit Hilfe eines Verbindungsringes 9, der in Fig. 2 vor dem Verschweißen mit Hilfe von Ultraschall oder dergleichen gezeigt ist. Die Materialeigenschaften dieses Verbindungsringes entsprechen im wesentlichen, insbesondere hinsichtlich Härte, denjenigen der äußeren Kappe 1.The two caps are permanently connected. This is done with the aid of a connecting ring 9, which is shown in FIG. 2 before welding with the aid of ultrasound or the like. The material properties of this connecting ring essentially correspond to those of the outer cap 1, particularly with regard to hardness.

Wenn das Verschweißen erfolgt ist, d.h. wenn die beiden Kappen miteinander dauerhaft verbunden sind, ist der Verbindungsring 9 niedriger als in Fig. 2 dargestellt, d.h. er liegt auf der Höhe des angrenzenden äußeren Dichtflansches 8. Die eigentliche Dichtfläche wird nur von dem weicheren Material des angrenzenden Dichtflansches 8 gebildet.When the welding is done, i.e. if the two caps are permanently connected to each other, the connecting ring 9 is lower than shown in Fig. 2, i.e. it lies at the level of the adjacent outer sealing flange 8. The actual sealing surface is formed only by the softer material of the adjacent sealing flange 8.

Die innere Kappe 2 weist einen inneren Dichtflansch 7 und einen äußeren Dichtflansch 8 auf. Der innere Dichtflansch 7 dient der Anlage an der entsprechenden Dichtfläche einer Flasche kleineren Durchmessers, wohingegen der äußere Dichtflansch 8 mit Hilfe der Überwurfmutter (äußere Kappe 1) mit der entsprechenden Dichtfläche einer Flasche größeren Durchmessers zur Anlage gebracht wird.The inner cap 2 has an inner sealing flange 7 and an outer sealing flange 8. The inner sealing flange 7 is used to contact the corresponding sealing surface of a bottle of smaller diameter, whereas the outer sealing flange 8 is brought into contact with the corresponding sealing surface of a bottle of larger diameter by means of the union nut (outer cap 1).

Der Universalflaschenverschluß dient der Verbindung mit Flaschen unterschiedlichen Durchmessers. Die Dichtflansche 7 und 8 sorgen in jedem Fall für eine gute und sichere Abdichtung.The universal bottle stopper is used to connect bottles of different diameters. The sealing flanges 7 and 8 always ensure a good and secure seal.

Mit 10 ist eine Belüftungsöffnung bezeichnet, wohingegen 11 einen Schlauch- oder Tropfanschluß bezeichnet.With 10 a ventilation opening is designated, whereas 11 denotes a hose or drip connection.
