Abstract
Description
Die Erfindung betrifft einen Verschluß der im Oberbegriff des Anspruchs genannten Art für eine Flasche oder dergleichen.The invention relates to a closure in the preamble of the type mentioned for a bottle or the like.
Durch DE 42 34 010 A1 ist ein Verschluß für eine Flasche oder dergleichen bekannt, der ein kappenförmiges Verschlußteil aufweist, das an seinem Rand einen nach innen gerichteten Vorsprung zum Hintergreifen eines nach außen gerichteten Vorsprungs an einem Hals einer Flasche oder dergleichen und in seinem Inneren im Bereich der Stirnkante eines Flaschenhalses eine Dichtfläche aufweist. Diese befindet sich an einer an dem Bodenbereich des Verschlußteils angeordneten Dichtung, die auf ihrer dem Boden des kappenförmigen Verschlußteils zugewandten Seite eine Ausnehmung aufweist, die sich von einem Radialbereich innen von der Anlagefläche der Dichtung einer Stirnfläche eines Halses einer Flasche radial nach außen erstreckt. Die Dichtfläche zur Anlage an der Stirnkante eines Flaschenhalses befindet sich auf der dem Boden des kappenförmigen Verschlusses abgewandten Seite der Dichtung, wobei die Dichtung entlang ihrem äußeren Rand einen dem Boden des Verschlußteils abgewandten Vorsprung aufweist, der den Hals einer Flasche außen in Axialrichtung umgreift.DE 42 34 010 A1 is a closure for a bottle or the like, which is a cap-shaped closure part has an inward on its edge directed projection for reaching behind an outward directed projection on a neck of a bottle or the like and inside one in the area of the front edge Bottle neck has a sealing surface. This is located arranged on one on the bottom region of the closure part Seal on their the bottom of the cap-shaped Closure part facing side has a recess, which differs from a radial area on the inside of the contact surface the seal of an end face of a neck Bottle extends radially outwards. The sealing surface for There is a system on the front edge of a bottle neck on the side facing away from the bottom of the cap-shaped closure Side of the seal, the seal being along its outer edge facing away from the bottom of the closure part Has projection that the neck of a bottle outside in the axial direction embraces.
Die Ausnehmung in der Dichtung auf der dem Boden des Verschlußteils zugewandten Seite ermöglicht ein Abheben der Dichtung von der Stirnfläche eines Halses einer Flasche bei Überdruck, so daß eine Druckentlastung stattfindet und ein Platzen einer Flasche vermieden wird. Außerhalb der Ausnehmung kann die Dichtung nicht abheben, und da das Material der Dichtung volumenkompressibel ist, bilden diese Bereiche der Dichtung einen Anschlag für den Verschluß, was insbesondere bei einem Schraubverschluß von besonderer Bedeutung ist. Dadurch ergeben sich definierte Andruckkräfte im Bereich der Dichtung, in der sich die Ausnehmung befindet. Damit ist der Druck, bei dem sich die Dichtung im Bereich der Ausnehmung von dem Flaschenhals abhebt, genau definiert, und zwar unabhängig von der Größe der Aufschraubkraft. Bewegungen des Bodenbereichs des kappenförmigen Verschlusses durch Aufwölbung als Folge von Druckerhöhungen werden bei diesem Verschluß nicht ausgenutzt.The recess in the seal on the bottom of the Closure part facing side allows lifting the Seal from the face of a neck of a bottle Overpressure, so that a pressure relief takes place and a Avoid bursting a bottle. Outside the recess can't lift the seal, and there the material of the seal is volume compressible these areas of the seal a stop for the Closure, which is particularly the case with a screw closure is of particular importance. This results in defined ones Pressure forces in the area of the seal, in the the recess is located. So that is the pressure at which is the seal in the area of the recess Bottle neck lifts up, precisely defined, independently on the size of the screwing force. Movements of the Bottom area of the cap-shaped closure through Bulge as a result of pressure increases will not used this closure.
Um die Anschlagwirkung der Dichtung bei diesem bekannten Verschluß zu verbessern, weist dessen Dichtung einen ringförmigen Bereich auf, in dem keine Zusammendrückung der Dichtung erfolgen kann. Dieser ringförmige Bereich liegt natürlich im Bereich der Stirnkante eines Flaschenhalses. Da dieser Bereich radial sehr klein ist, ergeben sich in der Praxis Schwierigkeiten um sicherzustellen, daß der ringförmige Bereich auf dem Flaschenhals aufliegt. Durch diesen ringförmigen Anschlagbereich ist der Bereich nur noch sehr klein, in dem die Dichtung anliegen und bei Überdruck abheben kann. Dadurch ergeben sich in der Praxis Dichtungsprobleme.To the impact of the seal on this to improve known closure, its seal an annular area where there is no compression the seal can be done. This ring-shaped The area is of course in the area of the front edge of a bottle neck. Because this area is radial is very small, difficulties arise in practice to ensure that the annular area rests on the bottle neck. Through this ring-shaped The area of impact is only very much small, in which the seal rests and in case of overpressure can take off. This results in sealing problems in practice.
Durch EP-A-0 581 568 ist ein Schraubverschluß aus Kunststoff bekannt, der eine Schraubkappe aufweist, in deren Inneren eine Dichtung angeordnet ist, die sich im aufgeschraubten Zustand sowohl auf die Stirnfläche einer zu verschließenden Flaschenöffnung, als auch auf die Außenfläche des Flaschenhalses im Bereich der Stirnkante anlegt. Durch diese Anordnung soll erreicht werden, daß beim öffnen der Flasche Innendruck aus der Flasche entweichen kann, bevor die Gewindegänge außer Eingriff kommen. Dadurch soll ein explosionsartiges Wegfliegen der Schraubkappe beim Öffnen vermieden werden. Ein Entweichen von Überdruck im verschlossenen Zustand ist nicht möglich.EP-A-0 581 568 is a screw closure known from plastic, which has a screw cap, inside which a seal is arranged, which is when screwed on both on the end face a bottle opening to be closed, as well the outer surface of the bottle neck in the area of the Front edge. This arrangement is intended to achieve be that when you open the bottle internal pressure from the Bottle can escape before the threads turn out Intervention come. This is said to be an explosive Flying screw caps can be avoided when opening. An escape of excess pressure in the closed Condition is not possible.
Durch FR-A-546399 ist ein Kronenverschluß für eine Flasche bekannt, der eine Kappe aus Blech aufweist, in deren Inneren eine Dichtung angeordnet ist, die eine Labyrinthdichtung darstellt, um ein hohes Maß an Abdichtung zu erzielen. Überdruck kann aus einer mit diesem Kronenverschluß verschlossenen Flasche nicht entweichen. FR-A-546399 is a crown closure for one Bottle known, which has a cap made of sheet metal, in the inside of which is arranged a seal, the one Labyrinth seal represents a high level of sealing to achieve. Overpressure can arise from one with this Do not escape the crown closure of the sealed bottle.
Der Erfindung liegt die Aufgabe zugrunde, einen Verschluß der im Oberbegriff des Anspruchs genannten Art zu schaffen, bei dem die Nachteile des bekannten Verschlusses vermieden sind, bei dem also insbesondere die Dichtwirkung bei größeren Toleranzen der Breite der Stirnkante eines Flaschenhalses und der radialen Lage derselben verbessert ist.The invention has for its object a closure of the type mentioned in the preamble of the claim create the disadvantages of the known closure are avoided, in particular the sealing effect with larger tolerances of the width of the front edge of a bottle neck and the radial position of the same is improved.
Die der Erfindung zugrundeliegende Aufgabe wird durch die im Kennzeichen des Anspruchs angegebene Lehre gelöst. The object underlying the invention is achieved by solved the teaching specified in the characterizing part of the claim.
Der Grundgedanke dieser Lehre besteht darin, an der Dichtung einen schrägen, im wesentlichen kegeligen Dichtflächenteil zu schaffen, der wenigstens einen Teil der Dichtfläche bildet und eine Zentrierung der Dichtung und Verbesserung der Abdichtung bewirkt. Diese ergibt sich dadurch, daß die schräge Fläche an der äußeren Begrenzung der Stirnkante eines Flaschenhalses zur Anlage kommt und dort eine erhöhte Flächenpressung bewirkt wird. Diese Pressung wird verringert oder aufgehoben, wenn sich bei Überdruck der Boden des Verschlußteiles nach außen wölbt, wodurch sich die Wirkung eines Überdruckventiles ergibt.The basic idea of this teaching is based on the Seal an oblique, essentially conical sealing surface part to create the at least part of the sealing surface forms and centering the seal and improvement the sealing effect. This results from that the sloping surface on the outer boundary of the front edge a bottle neck comes to the plant and there one increased surface pressure is caused. This squeeze will reduced or canceled if the floor is under pressure of the closure part bulges outwards, causing the Effect of a pressure relief valve results.
Es ist auch zweckmäßig, daß sich das Dichtflächenteil über die äußere Begrenzung der Stirnfläche eines Flaschenhalses hinaus erstreckt, wobei durch Bemessung des radialen Überstandes der Abblasdruck beeinflußbar ist. Kleinerer Überstand führt zu einem kleineren, größerer Überstand zu einem größeren Abblasdruck.It is also appropriate that the sealing surface part over the outer boundary of the end face of a bottle neck extends beyond, by dimensioning the radial Supernatant the blowdown pressure can be influenced. Smaller Supernatant results in a smaller, larger supernatant a larger blow-off pressure.
Die Neigung des Dichtflächenteils ist zweckmäßigerweise so gewählt, daß seine Bewegung vom Rand eines Flaschenhalses weg bei Wölbung des Bodens des kappenförmigen Verschlußteiles bei Druckerhöhung am größten ist. Durch das Maß der Neigung läßt sich auch in zweckmäßiger Weise der Druck beeinflussen, bei dessen Überschreitung die Dichtwirkung verringert wird oder ganz verschwindet und so das Abblasen von Überdruck erfolgt.The inclination of the sealing surface part is expedient chosen so that its movement from the edge of a bottle neck away with curvature of the bottom of the cap-shaped closure part is greatest when the pressure is increased. By the degree of inclination the pressure can also be suitably influenced, if it is exceeded, the sealing effect is reduced becomes or disappears completely and thus the blowing off of Overpressure occurs.
Die radiale Ausdehnung des geneigten Dichtflächenteils erstreckt sich zweckmäßigerweise wenigstens über den Toleranzbereich der radial äußeren Begrenzung der Stirnfläche eines Halses einer Flasche. Dadurch ist die Funktion des geneigten Dichtflächenteils bei allen vorkommenden radialen Maßen der äußeren Begrenzung der Stirnfläche der Flaschenhälse von mit dem Verschluß zu schließenden Flaschen sichergestellt. The radial expansion of the inclined sealing surface part expediently extends at least over the tolerance range the radially outer boundary of the end face a neck of a bottle. This is the function of the inclined sealing surface part with all occurring radial Dimensions of the outer boundary of the end face of the bottle necks of bottles to be closed with the closure.
Der Dichtflächenteil und der Vorsprung sind zweckmäßigerweise an einer in dem Boden des kappenförmigen Verschlußteiles angeordneten Dichtung vorgesehen. Das Material dieser Dichtung kann dann unabhängig von dem des kappenförmigen Verschlusses gewählt und so den Dichtbedingungen angepaßt werden.The sealing surface part and the projection are expedient on one in the bottom of the cap-shaped closure part arranged seal provided. The material of this Seal can then be independent of that of the cap-shaped Closure chosen and thus adapted to the sealing conditions become.
Bei Verwendung einer solchen gesonderten Dichtung ist es zweckmäßig, daß diese auf der dem Boden zugewandten Seite wenigstens eine Ausnehmung aufweist, die sich von einem Radialbereich innen von der Stirnfläche eines Halses einer Flasche nach radial außen erstreckt. Dabei ist es zweckmäßig, daß sich die Ausnehmung bis in die Außenfläche des Vorsprunges erstreckt. Im Bereich der Ausnehmung ist die Dichtung nachgiebig, so daß sie bei Überdruck ausweichen und den Abblasvorgang bei Überdruck unterstützen kann.When using such a separate seal it is advisable that this on the side facing the floor has at least one recess, which extends from a radial region inside of the face of a neck one Bottle extends radially outward. It is advisable that the recess extends into the outer surface of the projection extends. The seal is in the area of the recess compliant, so that they dodge under pressure and the Blow-off process can support at overpressure.
