Description

Die Erfindung betrifft einen Flaschenverschluss, insbesondere für Sektflaschen, bei welchem der einstückig aus Kunststoff ausgebildete Verschlusskörper einen stopfenartig in den Flaschenhals eintretenden Abdichtungsschaft besitzt, der zentrisch von der Bodeninnenfläche einer Kappe ausgeht, deren Mantelwandung auf ihrer Innenfläche mit Gewinde ausgestattet ist, das in Eingriff steht zum Aussengewinde des Flaschenhalses, und welcher Abdichtungsschaft auf dem das Gewinde tragenden Bereich vorsteht und mindestens eine über seine Umfangsfläche vorstehende, in einer Querebene liegende ringförmige Abdichtungsrippe besitzt.The invention relates to a bottle stopper, in particular for champagne bottles, in which the closure body, which is formed in one piece from plastic, has a sealing shaft, which enters the bottle neck like a stopper and extends centrally from the bottom inner surface of a cap, the jacket wall of which is provided with a thread on its inner surface, which is in engagement to the external thread of the bottle neck, and which sealing shaft protrudes on the area carrying the thread and has at least one annular sealing rib projecting over its circumferential surface and lying in a transverse plane.

Ein Flaschenverschluss dieser Art ist durch die DE-A Nr. 2614538 bekannt. Die ringförmige Abdichtungsrippe liegt dort im Gewindebereich, und zwar im bodeninnenseitigen Endbereich des Abdichtungsschaftes. Sie setzt sich von dort in eine schraubengangförmig zum vorstehenden Abschnitt weiterlaufende Rippe fort. Letztere bildet zusammen mit der Innenwand des Flaschenhalses einen wendelförmig ansteigenden Kanal. Beim Abschrauben der Kappe hebt die auf einer Querebene liegende, geschlossene Abdichtungsrippe mündungsseitig von der Innenwand des Flaschenhalses ab, so dass bei CO2-haltigen Flüssigkeiten das Gas über diesen Weg entweichen kann. Es tritt in den beim Abschrauben freigewordenen Ringraum der Kappe und von dort aus über einen vom Aussengewinde gebildeten Weg des Flaschenhalses nach aussen. Beim Abheben der Abdichtungsrippe entsteht ein Geräusch, welches dem Benutzer anzeigt, dass der Flascheninhalt von jetzt ab gefahrlos ausgebracht werden kann. Hierzu bedarf es aber noch des weiteren Abschraubens. Diese von der Schraubbewegung kontrollierte Öffnungsbewegung lässt nicht das bei normalen Sektflaschen auftretende Knallgeräusch entstehen, so dass allenfalls ein gewisses Zischgeräusch auftritt. Dieses wird aber, da der Öffnungsbereich von der Kappe noch überfangen ist, erheblich gedämpft. Da der Gasaustritt nicht plötzlich und unbehindert stattfinden kann, sondern durch den relativ schmalen Kanalquerschnitt verzögert wird, kann ein vorzeitiges Aufschäumen dazu beitragen, dass das Füllgut mitgerissen wird und es so zu an sich unnötigen Verlusten kommt.A bottle stopper of this type is known from DE-A No. 2614538. The annular sealing rib lies there in the threaded area, specifically in the end region of the sealing shaft on the inside of the floor. From there it continues into a rib running in the shape of a helix to the protruding section. The latter, together with the inner wall of the bottle neck, forms a helically rising channel. When the cap is unscrewed, the closed sealing rib lying on a transverse plane lifts off from the inside wall of the bottle neck on the mouth side, so that the gas can escape via CO 2 -containing liquids. It enters the annular space of the cap that is released when unscrewing and from there via a path of the bottle neck formed by the external thread to the outside. When the sealing rib is lifted off, a noise is generated which indicates to the user that the contents of the bottle can now be safely removed. This requires further unscrewing. This opening movement, which is controlled by the screwing movement, does not cause the crackling noise that occurs with normal champagne bottles, so that at most a certain hissing noise occurs. However, since the opening area is still covered by the cap, this is dampened considerably. Since the gas can not escape suddenly and unhindered, but is delayed by the relatively narrow channel cross-section, premature foaming can contribute to entrainment of the contents and thus lead to unnecessary losses.

Durch die FR-A Nr. 2306896 ist ein ähnlicher Verschlusskörperfür Flaschen bekannt, dessen Innengewinde tragende Kappenmantelwandung beim Aufprellen in das entsprechende Gegengewinde des Flaschenhalses einspringt. Die Dehnung der Mantelwand erfolgt in einem Masse, dass der den verdickten Bereich des Flaschenhalses übergreifende, unten vorragende, einen Innenwulst tragende Kappenrand in seine Ausgangsstellung zurücktritt. Hier befindet sich das Gewinde aber auch noch in Eingriff, wenn der Abdichtungsschaft in seine Öffnungsstellung getreten ist. Der Kappeninnenseitige Randwulst verhindert überdies das plötzliche Abspringen des Verschlusskörpers, da sich der der Gewindehöhe entsprechende Wulst im Aussengewinde des Flaschenhalses verfängt. Die notwendige Elastizität des Materiales macht den Verschluss unsicher.From FR-A No. 2306896 a similar closure body for bottles is known, the inner thread-bearing cap jacket wall of which jumps into the corresponding mating thread of the bottle neck when it is bounced. The jacket wall is stretched to such an extent that the cap rim, which projects over the thickened area of the bottle neck and protrudes at the bottom and carries an inner bead, returns to its starting position. Here, however, the thread is still engaged when the sealing shaft has entered its open position. The inside bead on the cap also prevents the closure body from suddenly jumping off, since the bead corresponding to the thread height gets caught in the external thread of the bottle neck. The necessary elasticity of the material makes the closure unsafe.

Aufgabe der Erfindung ist es, hier Abhilfe zu schaffen und einen gattungsgemässen Flaschenverschluss unter Beibehaltung des vorteilhaften einstückigen Aufbaus so auszubilden, dass das beim Öffnen der Flasche auftretende Geräusch mit Knallartigem Charakter und zeitlich so zu erzwingen, wie es beim Öffnen von Sektflaschen mit normalem, drahtgesicherten Korbverschlussstopfen üblich und attraktiv ist.The object of the invention is to remedy this situation and to design a generic bottle stopper while maintaining the advantageous one-piece construction in such a way that the noise that occurs when the bottle is opened is of a bang-like character and is forced in time as it is when opening champagne bottles with a normal, wire-secured one Basket plug is common and attractive.

Gelöst ist diese Aufgabe durch die im Anspruch 1 angegebene Erfindung.This object is achieved by the invention specified in claim 1.

Der Unteranspruch betrifft eine vorteilhafte Weiterbildungdeserfindungsgemässen Flaschenverschlusses.The subclaim relates to an advantageous development of the bottle stopper according to the invention.

Zufolge solcher Ausgestaltung ist ein gattungsgemässer Flaschenverschluss von insbesondere erhöhtem Gebrauchswert geschaffen: Sobald der Gewindebereich durchlaufen ist, springt der stopfenartige Verschlusskörper unter Erzeugung des gewünschten "Plopp"- Effekts ab, da die querliegende, ringförmig geschlossene Abdichtungsrippe des Abdichtungssehaftes dem Gewindebereich vorgelagert ist. Die Abdichtungsrippe kann sich direkt an den Gewindebereich anschliessen; es kann aber auch noch ein gewisser Abstand dazu eingehalten werden. Das Gewinde bestimmt nicht mehr den Öffnungsvorgang; es bringt vielmehr nur die Öffnungsbereitstellung des Flaschenverschlusses. Daher steht es bezüglich einer gängigen Handhabung dahingehend, das Abspringen mehr oder weniger dem Zufall zu überlassen, nicht im Wege. Dadurch, dass mehrere Abdichtungsrippen sowohl innerhalb des mit dem mehrgängigen Gewinde überlappenden Bereichs als auch ausserhalb des Bereichs des Gewindes vorgesehen sind, liegt einerseits eine den erwähnten Toleranzen noch besser rechnungtragende Ausgestaltung vor. Andererseits ergibt sich durch die Mehrgängigkeit der Vorteil, dass der Austritt aus dem Gegengewinde des Flaschenhalses ohne jede Kipptendenz erfolgt, wie dies bei einem eingängigen Gewinde unterstellt werden kann. Eine solche, wenn auch geringe Neigungslage des Abdichtungschaftes kann nämlich im Verein mit Fertigungstoleranzen zu einem unerwünschten Entweichen von C02 führen, so dass der gewünschte "Plopp" - Effekt entfällt. Schliesslich ist es von Vorteil, dass die Aussenform des Verschlusskörpers Kugelförmig gestaltet ist und die Innenfläche der Mantelwand in drei hintereinanderliegenden Stufenabschnitten verläuft, von denen der Mittlere die Gewindegänge trägt, die bis zu einem als bodeninnenwandseitige Abstützfläche für den Flaschenhals dienenden Stufenabschnitt reichen, der teilweise in eine Ringnut am Fuss des Bedienungsschaftes übergeht. Die einzelnen Stufenabschnitte sind so den stabilisatorischen Erfordernissen entsprechend günstigst genutzt, insbesondere im Hinblick auf die gewählte kurbelförmige Aussenform des Verschlusskörpers: So ergibt sich für den die Abstützfläche bildende Stufenabschnitt eine Flächenverringerung, die zu einer Art dreieckigen Dichtlippe führt. Hierdurch ist eine wirksame zusätzliche Dichtung von aussen her erzielt. Der querschnittsbreitere Stufenabschnitt ist für die Schaffung eines möglichst tiefen Gewindes genutzt. Der letzte, kappenrandseitige Stufenabschnitt dagegen bildet eine den Flaschenwulst umgebende, dünnwandigere Schürze.As a result of such an embodiment, a generic bottle stopper of particularly high utility value is created: as soon as the thread area has been run through, the stopper-like closure body jumps off, producing the desired "plop" effect, since the transverse, annularly closed sealing rib of the sealing adhesive is located in front of the thread area. The sealing rib can directly adjoin the thread area; a certain distance from it can also be maintained. The thread no longer determines the opening process; it rather only brings the opening of the bottle stopper. Therefore, there is no obstacle to common handling in terms of leaving the jumping more or less up to chance. Due to the fact that several sealing ribs are provided both within the area overlapping with the multi-start thread and outside the area of the thread, on the one hand there is an embodiment which takes account of the tolerances mentioned even better. On the other hand, the multiple threads result in the advantage that the exit from the counter thread of the bottle neck takes place without any tendency to tip, as can be assumed with a single-start thread. Such, albeit slight, inclination of the sealing shaft, in combination with manufacturing tolerances, can lead to an undesired escape of C0 2 , so that the desired "plop" effect is eliminated. Finally, it is advantageous that the outer shape of the closure body is spherical and the inner surface of the casing wall runs in three successive step sections, the middle of which carries the threads that extend up to a step section serving as a support surface for the bottle neck on the inside of the bottom wall, which partly in there is an annular groove at the foot of the operating shaft. The individual step sections are thus used most favorably in accordance with the stabilization requirements, in particular with regard to the selected crank-shaped outer shape of the closure body: this results in a reduction in area for the step section forming the supporting surface, which results in a kind of triangular Sealing lip leads. This provides an effective additional seal from the outside. The step section with a wider cross-section is used to create the deepest possible thread. The last step section on the edge of the cap, on the other hand, forms a thin-walled apron surrounding the bottle bead.

Der Flaschenverschluss 1 ist als kugelförmige Kappe gestaltet. Er ist als einstückig aus Kunststoff gefertigter Verschlusskörper realisiert.The bottle stopper 1 is designed as a spherical cap. It is realized as a one-piece closure body made of plastic.

Zentrisch von der Bodeninnenfläche 2 geht ein freistehend angeordneter, zylindrischer Abdichtungsschaft 3 aus zum stopfenartigen Eintritt in die Öffnung 4 des Halses 5 einer Flasche 6.A free-standing, cylindrical sealing shaft 3 extends centrally from the bottom inner surface 2 for plug-like entry into the opening 4 of the neck 5 of a bottle 6.

Zur Erzielung des erforderlichen Dichtschlusses besitzt der Abdichtungsschaft 3 mehrere über seine Mantel- bzw. Umfangsfläche 3' vorstehende ringförmige, gleichhohe Abdichtungsrippen 7. Die Innenwand 11' des Flaschenhalses 5 ist mindestens über den Eintauchbereich des zuvorderst liegenden Abdichtungsringes 7 zylinderförmig gestaltet. Letztere verlaufen in Querebene E-E und sind in einem Abstand zueinander angeordnet, der mindestens der anderthalbfachen Breite einer Abdichtungsrippe 7 entspricht. Ihr Querschnitt ist in Fig. 1 halbkreis- und in Fig. 2 dreieckförmig. Es handelt sich um eine gleichseitige Dreieckform, wobei die eine Seite des Dreiecks in der zylindrischen Umfangsfläche 3' des Abdichtungsschaftes 3 wurzelt.In order to achieve the required tight closure, the sealing shaft 3 has a plurality of annular, equally high sealing ribs 7 protruding beyond its jacket or circumferential surface 3 '. The inner wall 11' of the bottle neck 5 is of cylindrical design at least over the immersion area of the sealing ring 7 lying in front. The latter run in the transverse plane E-E and are arranged at a distance from one another which corresponds to at least one and a half times the width of a sealing rib 7. Their cross section is semicircular in Fig. 1 and triangular in Fig. 2. It is an equilateral triangular shape, one side of the triangle being rooted in the cylindrical peripheral surface 3 'of the sealing shaft 3.

Die Verteilung der einzelnen Abdichtungsrippen 7 auf dem Abdichtungsschaft 3 ist dergestalt, dass sich mehrere Abdichtungsrippen 7 im Bereich eines Gewindes 8 der Kappe erstrecken. Letzteres ist als einwärtsgerichteter Vorsprung V auf der Innenfläche 9' einer den Abdichtungsschaft 3 konzentrisch umgebenden Mantelwand 9 ausgebildet und steht in Eingriff mit dem korrespondierenden Aussengewinde 10 am Hals 5 einer Flasche, insbesondere Sektflasche 6 (vgl. Fig. 2).The distribution of the individual sealing ribs 7 on the sealing shaft 3 is such that a plurality of sealing ribs 7 extend in the area of a thread 8 of the cap. The latter is designed as an inward projection V on the inner surface 9 'of a jacket wall 9 which concentrically surrounds the sealing shaft 3 and is in engagement with the corresponding external thread 10 on the neck 5 of a bottle, in particular a champagne bottle 6 (cf. FIG. 2).

Der Abdichtungsschaft 3 steht über den als mehrgängiges Gewinde 8 ausgebildeten Vorsprung V vor; mindestens eine der Abdichtungsrippen 7 befindet sich auf Höhe des letzten, dem Flaschenhals 5 zugewandten Gewindeganges 8' oder jenseits desselben, also auf dem vorstehenden Abschnitt A des Abdichtungsschaftes 3. Dies hat zur Folge, dass bis zum Austritt des Gewindes 8 aus dem Aussengewinde 10 des Flaschenhalses 5 Dichtschluss vorliegt. Der durch das Freiwerden von Kohlensäure erhöhte Innendruck presst nun den Verschlusskörper schlagartig unter Erzeugung des gewünschten "Plopp"-Effekts aus der Verschlussstellung. Da zum Zeitpunkt des Gewindeaustritts praktisch nur noch eine Abdichtungsrippe 7 in Dichteingriff mit dem Flaschenhals steht, treten die darüber angeordneten Abdichtungsrippen 7 nicht mehr, bzw. nicht mehr alle, als Reibungsfaktor auf. Es kommt zu einer schlagartigen Freigabe der Flaschenmündung.The sealing shaft 3 protrudes beyond the projection V formed as a multi-start thread 8; At least one of the sealing ribs 7 is located at the level of the last thread turn 8 'facing the bottle neck 5 or beyond it, that is to say on the projecting section A of the sealing shaft 3. This has the consequence that until the thread 8 emerges from the external thread 10 Bottleneck 5 tight closure is present. The increased internal pressure due to the release of carbonic acid now suddenly presses the closure body to produce the desired " plop" effect from the closed position. Since practically only one sealing rib 7 is in sealing engagement with the bottle neck at the time the thread emerges, the sealing ribs 7 arranged above it no longer occur, or not all, as a friction factor. The bottle mouth is suddenly released.

Durch das mehrgängige Gewinde 8 und entsprechend gestaltete Aussengewinde 10 ist die erforderliche kippfreie Verlagerung des Abdichtungsschaftes 3 sichergestellt. Im allgemeinen genügt ein zweigängiges Gewinde, wobei die Gewindeausläufer 8" dann diametral einander gegenüberliegen. Günstiger ist ein dreigängiges Steilgewinde zufolge des hieraus zu gewinnenden Dreipunktabgriffs bzw. Gewindeaustritts der beiden Gewinde (Fig. 3).The multi-thread 8 and correspondingly designed external thread 10 ensure the necessary tilt-free displacement of the sealing shaft 3. In general, a two-start thread is sufficient, the thread extensions 8 "then being diametrically opposite one another. A three-start helix thread is more favorable due to the three-point tap or thread outlet of the two threads to be obtained therefrom (FIG. 3).

Die Innenfläche 9' der Mantelwand 9 verläuft in drei hintereinanderliegenden Stufenabschnitten. Der mittlere Stufenabschnitt trägt das mehrgängige Gewinde 8. Oberhalb des Gewindes, d. h. in Richtung der Bodeninnenfläche 2 gesehen, reicht das Gewinde 8 bis zu einer vom nächsten Stufenabschnitt gebildeten Abstützfläche 13 für die Stirnringfläche 14 des Flaschenhalses 5. Die ringförmige Abstützfläche 13 bringt eine zusätzliche Abdichtung der Kappe auf dem Flaschenhals 5. Die Stützfläche 13 geht teilflächig in eine Ringnut 15 über. Letztere umgibt konzentrisch den Fuss des Abdichtungsschaftes 3. Aufgrund der Flächenverringerung der Abstützfläche 13 ist der Dichteffekt noch erhöht. So liegt ein mehr lippenartiger Vorsprung vor.The inner surface 9 'of the jacket wall 9 runs in three successive step sections. The middle step section carries the multi-start thread 8. Above the thread, i. H. Seen in the direction of the bottom inner surface 2, the thread 8 extends to a support surface 13 formed by the next step section for the end ring surface 14 of the bottle neck 5. The ring-shaped support surface 13 provides an additional seal of the cap on the bottle neck 5. The support surface 13 is partially in one Ring groove 15 over. The latter concentrically surrounds the base of the sealing shaft 3. Due to the reduction in the area of the support surface 13, the sealing effect is increased. So there is a more lip-like projection.

Die Innenwand 16 des hohl zylindrisch ausgebildeten, zum Flaschenhals 5 hin offenen Abdichtungsschaftes 3 ist mit mehreren Längsriffeln 16' versehen. Die entsprechende Höhlung dient gemäss Fig. 2 zur Aufnahme eines Korkens 17, sollte ein solcher bei hochwertigem Flascheninhalt gewünscht sein. Die Riffelung trägt zu seiner Festlegung bei, die zudem noch durch die schafteinwärts gerichtete Druckbelastung im Flaschenhals vergrössert wird.The inner wall 16 of the hollow cylindrical sealing shaft 3 which is open towards the bottle neck 5 is provided with a plurality of longitudinal corrugations 16 '. The corresponding cavity serves as shown in FIG. 2 for receiving a cork 17, should such be desired in the case of high-quality bottle contents. The corrugation contributes to its definition, which is further increased by the inward pressure on the bottle neck.

Beim dargestellten Ausführungsbeispiel ist die Innenwand 11' des Flaschenhalses 5 strichpunktiert dargestellt. Demgegenüber ist der Abdichtungsschaft in seiner körperlichen Form wiedergegeben, um das Profil der Abdichtungsrippen 7 in der Grundform wiedergeben zu können. Beim auftretenden Presssitz ergibt sich die natürliche Deformierung bzw. ein Flacherdrücken der Rippen.In the illustrated embodiment, the inner wall 11 'of the bottle neck 5 is shown in broken lines. In contrast, the sealing shaft is shown in its physical shape in order to be able to reproduce the profile of the sealing ribs 7 in the basic shape. When a press fit occurs, the natural deformation or a flattening of the ribs results.

Das Bestücken der Flasche mit dem erfindungsgemässen Flaschenverschluss ist erleichtert durch die Massnahme, dass die zuordnungsseitige Aussenkante des Abdichtungsschaftes 3 bei 18 gefast ist. Eine entsprechende Fasung 19 befindet sich an der Innenkante der Stirnringfläche 14 des Flaschenhalses 5.Fitting the bottle with the bottle cap according to the invention is made easier by the measure that the outer edge of the sealing shaft 3 on the side of the assignment is chamfered at 18. A corresponding chamfer 19 is located on the inner edge of the end ring surface 14 of the bottle neck 5.

Die Griffigkeit des Flaschenverschlusses wird durch aussen an der Kappe vorgesehene, vertikal ausgerichtete Riffeln 20 erhöht. Unterbrochen sind die Riffeln 20 auf Höhe des Gewindebereichs, indem dort eine Ringrippe 21 um den ganzen Kugelumfang verläuft, und zwar im wesentlichen im Bereich der horizontalen Kugelmittelebene. Sie stellt eine vorteilhafte, stabilisierend wirkende Umreifung dar zufolge der über die dortige schon vergrösserte Wandungsdicke hinausgehende Materialanhäufung.The grip of the bottle stopper is increased by vertically oriented corrugations 20 provided on the outside of the cap. The corrugations 20 are interrupted at the level of the thread area, in that an annular rib 21 extends around the entire circumference of the ball, essentially in the area of the horizontal center plane of the ball. they represents an advantageous, stabilizing strapping according to the material accumulation going beyond the already increased wall thickness there.

Unterhalb des Gewindes 8 geht die Mantelwand 9 in eine querschnittsverringerte Zone über. Diese bildet eine den Bund 22 des Flaschenhalses ganz oder teilweise überfangende Schürze 23.Below the thread 8, the jacket wall 9 merges into a zone with a reduced cross section. This forms an apron 23 that completely or partially overlaps the collar 22 of the bottle neck.

Beim Wiederverschliessen der Flasche mit dem Flaschenverschluss 1 wird der Handhabende zunächst einen geringen Widerstand überwinden müssen, und zwar den Widerstand, der erforderlich ist, die bis zuletzt die Abdichtung aufrechterhaltende untere Abdichtungsrippe 7 in den Flaschenhals zu verbringen. Erst dann greift beim Verschrauben das dreigängige Gewinde der Kappe in das Aussengewinde des Flaschenhalses 5 ein.When the bottle is reclosed with the bottle stopper 1, the operator will first have to overcome a slight resistance, namely the resistance that is required to place the lower sealing rib 7, which maintains the seal, in the bottle neck. Only then does the three-start thread of the cap engage in the external thread of the bottle neck 5 when screwing.

Alle in der Beschreibung erwähnten und in der Zeichnung dargestellten neuen Merkmale sind erfindungswesentlich, auch soweit sie in den Ansprüchen nicht ausdrücklich beansprucht sind.All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
