Abstract

A method for producing a closure for a bottle which has a holding part (16), a sealing part (17), and a seal made of compressible material which is arranged between the annular sealing surface of the sealing part and an annular end face of the bottle neck (20) and, in the closed state, rests both against the sealing surface of the sealing part (17) and against the end face of the bottle neck (20) in the circumferential direction with different contact pressure. The method is characterised in that a sealing disc (18) made of compressible material is inserted into a cap, forming the holding part (16) and sealing part (17), with a flat sealing surface of the sealing part (17) and made of a deformable metal, in that the cap is fitted with the sealing disc (18) onto the bottle neck (20), in that a pressing ram (21) is pressed from the outside against the sealing part (17) of the cap, which pressing ram has on its end face projections (24) arranged spaced apart in the circumferential direction so that the sealing part (17) is deformed only at the points on these projections (24) in the direction towards the end face of the bottle neck (20) so that the seal is compressed to a lesser extent in the region of the non-deformed parts. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Verschlusses der im Oberbegriff des Anspruchs 1 genannten Art für eine Flasche oder dergleichen.The invention relates to a method for producing a closure of the type mentioned in the preamble of claim 1 for a bottle or the like.

Durch DE 36 42 998 C1 ist ein Verschluß bekannt, bei dem zusätzlich zu der radialen, stirnseitigen Dichtfläche axiale Dichtflächen im Bereich des Mündungsrandes einer Flasche vorgesehen sind, in die sich Dichtmassse der Dichtung erstreckt. Das Dichtteil ist tiefgezogen und erstreckt sich um den Mündungsrand der Flasche herum, um so die äußere, axiale Dichtfläche zu bilden. Das Wesentliche dieses bekannten Verschlusses soll darin bestehen, daß das Dichtteil wenigstens in einem Teilbereich am Übergang von dem Dichtteil zu dem Halteteil nicht bis auf den seitlichen Mündungsrand des Halses der Flasche tiefgezogen ist, vielmehr von einer derartigen Verformung ausgenommen ist. Auf diese Weise soll in dem unverformten Teilbereich eine verminderte Dichtstrecke geschaffen sein, die aufgrund ihrer Kürze zu einer geringeren Dichtigkeit führen soll. Auf diese Weise soll ein Entweichen von Überdruck begünstigt werden. Das Entweichen von Überdruck ist bei einem derartigen Verschluß jedoch weniger von der Dichtstrecke als vielmehr von dem Auflagedruck der Dichtung abhängig. Dieser ist jedoch bei diesem bekannten Verschluß über den gesamten Mündungsrand gleich. Die gewünschte Wirkung eines Überdruckventils wird daher nur sehr unvollkommen erreicht.From DE 36 42 998 C1 a closure is known in which, in addition to the radial sealing face on the face, axial sealing surfaces are provided in the region of the mouth edge of a bottle, into which the sealing compound of the seal extends. The sealing part is deep-drawn and extends around the mouth of the bottle so as to form the outer, axial sealing surface. The essence of this known closure should consist in the fact that the sealing part, at least in a partial area at the transition from the sealing part to the holding part, is not deep-drawn down to the lateral mouth edge of the neck of the bottle, but is rather excluded from such a deformation. In this way, a reduced sealing distance is to be created in the undeformed partial area, which, due to its brevity, should result in less tightness. In this way, the escape of excess pressure is to be promoted. With such a closure, the escape of excess pressure is less dependent on the sealing section than on the contact pressure of the seal. In this known closure, however, this is over the entire rim of the mouth equal. The desired effect of a pressure relief valve is therefore only very incompletely achieved.

Durch die DE 37 44 292 C1 ist ein Verschluß für eine Flasche oder dergleichen bekannt, der einen kappenförmigen Halteteil aufweist, an dem sich ein nach innen gerichteter Vorsprung oder Kragen zum Hintergreifen eines Außenwulstes eines Flaschenhalses befindet. Dieses Halteteil ist über ein elastisches Element mit einem Dichtteil mit einer ringförmigen Dichtfläche zur Anlage an einer Stirnfläche des Flaschenhalses verbunden. Das Halteteil weist einen Anschlag zur definierten Anlage des Halteteils an dem Rand des Flaschenhalses auf. Da das Dichtteil ebenfalls an dem Rand des Flaschenhalses anliegt, ist dadurch die gegenseitige Lage von Halteteil und Dichtteil genau definiert. Da sich zwischen beiden das elastische Element zur Vorspannung des Dichtteils befindet, ist damit auch die Größe der Vorspannung des elastischen Elements genau definiert und damit der Druck, bei dem das Dichtteil abhebt, das Überdruckventil also öffnet.From DE 37 44 292 C1 a closure for a bottle or the like is known which has a cap-shaped holding part on which there is an inward projection or collar for engaging behind an outer bead of a bottle neck. This holding part is connected via an elastic element to a sealing part with an annular sealing surface for contact with an end face of the bottle neck. The holding part has a stop for the defined contact of the holding part on the edge of the bottle neck. Since the sealing part also abuts the edge of the bottle neck, the mutual position of the holding part and the sealing part is precisely defined. Since the elastic element for prestressing the sealing part is located between the two, the size of the prestressing of the elastic element is also precisely defined and thus the pressure at which the sealing part lifts off, that is to say opens the pressure relief valve.

Durch die US-PS 40 89 434 ist ein Schraubverschluß der im Oberbegriff des Anspruchs 1 genannten Art bekannt, bei dem zwischen dem Boden der Schraubkappe und dem Stirnrand des Flaschenhalses eine Dichtung aus Schaumstoff liegt, die in ihrem Querschnitt in einer diametralen Richtung unterschiedliche Dicken hat. Beim Aufschrauben werden also die Bereiche größerer Dicke stärker zusammengepreßt als die Bereiche geringerer Dicke. In den Bereichen geringerer Dicke ist daher die Dichtkraft geringer, und diese Bereiche sollen als Überdruckventil dienen. Der Öffnungsdruck hängt dabei von der Kompression der gesamten Dichtung ab, ist somit nicht unabhängig vom Aufschraubdrehmoment. Erfolgt das Aufschrauben mit zu geringem Drehmoment, so sind die Bereiche geringerer Dicke nicht zur Anlage gebracht, die Dichtung ist nicht dicht. Wird die Dichtung mit zu großer Kraft aufgeschraubt, so ist die Anlagekraft auch im Bereich der geringeren Dicke zu groß, so daß entsprechend auch der Öffnungsdruck groß ist und die Gefahr einer Explosion der Flasche nach sich zieht. Hinzu kommt der besondere Nachteil, daß der größte Teil des Drehmoments beim Aufschrauben auf das Zusammendrücken der Bereiche der Dichtung großer Dicke entfällt, zumal deren Fläche wesentlich größer ist als die Fläche der Bereiche geringerer Dicke, so daß der erhöhte Anstieg des Drehmoments durch die zusätzliche Zusammendrückung im Bereich der Stellen geringerer Dicke der Dichtung kaum feststellbar ist, insbesondere nicht dann, wenn das Aufschrauben von Hand erfolgt. Das Aufschrauben von Hand ist aber im praktischen Gebrauch der Normalfall und entscheidend. Die Gefahr von Explosionen besteht also im Normalfall weiterhin.From US-PS 40 89 434 a screw cap of the type mentioned in the preamble of claim 1 is known, in which between the bottom of the screw cap and the front edge of the bottle neck is a seal made of foam, which has different thicknesses in its cross section in a diametrical direction . When screwing on, the areas of greater thickness are thus pressed together more than the areas of reduced thickness. The sealing force is therefore less in the areas of reduced thickness, and these areas are intended to serve as a pressure relief valve. The opening pressure depends on the compression of the entire seal and is therefore not independent of the screwing torque. If the screwing is done with too little torque, the areas of reduced thickness are not brought into contact, the seal is not tight. If the seal is screwed on with too much force, the contact force is also too great in the area of the smaller thickness, so that accordingly Opening pressure is high and there is a risk of explosion of the bottle. In addition, there is the particular disadvantage that most of the torque when screwing is due to the compression of the areas of the gasket of large thickness, especially since their area is substantially larger than the area of the areas of lesser thickness, so that the increased increase in torque due to the additional compression is hardly noticeable in the area of thinner seal thickness, especially not when screwing on by hand. However, screwing on by hand is the normal case in practical use and is decisive. The danger of explosions therefore normally continues to exist.

Durch die DE 1 432 224 A1 ist eine Entlüftungsdichtung für einen Verschluß ähnlich der zuvor behandelten US-PS 4 089 434 bekannt, wobei der Unterschied darin besteht, daß sich die Bereiche geringerer Dicke der Dichtung nur an zwei diametral gegenüberliegenden kurzen Umfangsstellen befinden. Der größte Teil der Dichtung hat die größere Dicke. Die zuvor beschriebenen Nachteile sind daher noch größer.DE 1 432 224 A1 discloses a ventilation seal for a closure similar to the previously discussed US Pat. No. 4,089,434, the difference being that the areas of reduced thickness of the seal are located only at two diametrically opposed short circumferential locations. Most of the seal is thicker. The disadvantages described above are therefore even greater.

Durch die US-PS 3 114 467 sowie die deutsch Gebrauchsmusterschrift 8 122 918 O 1 sind kappenförmige Verschlüsse mit Überdrucksicherungen bekannt, bei denen jeweils im Boden eine ebene Dichtscheibe angeordnet ist, hinter der sich an einigen Umfangsstellen Ausnehmungen befinden. Ist eine solche Kappe auf den Hals einer Flasche aufgeschraubt und entsteht ein Druck in der Flasche, so hebt sich der Rand der scheibenförmigen Dichtung an den Stellen, an denen sich die Ausnehmungen im Boden der Kappe befinden, etwas an, so daß Überdruck entweichen kann. Ein Nachteil dieser bekannten Schraubverschlüsse besteht darin, daß im Bereich der Ausnehmungen im Boden der Schraubkappen überhaupt keine Anpreßung des Randes der Dichtscheibe an den Stirnrand des Flaschenhalses erfolgt. Das Innere der Flasche, beispielsweise eine Getränkeflüssigkeit, kann daher schon bei geringsten Überdrücken aus der Flasche entweichen, was nicht erwünscht ist. Außerdem besteht der Nachteil, daß gerade bei Glasflaschen durch die herstellungsbedingten Toleranzen oder bei Verunreinigungen auf der Stirnfläche des Flaschenrandes bzw. auf der Dichtung eine Dichtanlage der Dichtung an der Stirnfläche des Flaschenhalses unmöglich ist.From US-PS 3 114 467 and the German utility model 8 122 918 O 1 cap-shaped closures with overpressure protection are known, in each of which a flat sealing washer is arranged in the floor, behind which there are recesses at some circumferential locations. If such a cap is screwed onto the neck of a bottle and there is pressure in the bottle, the edge of the disc-shaped seal rises slightly at the points where the recesses are in the bottom of the cap, so that excess pressure can escape. A disadvantage of these known screw closures is that in the area of the recesses in the bottom of the screw caps there is no pressing of the edge of the sealing disk against the end edge of the bottle neck. The inside of the bottle, for example a beverage liquid, can therefore escape from the bottle at the slightest excess pressure, which is not desirable. In addition, there is the disadvantage that, especially in the case of glass bottles, the manufacturing tolerances or impurities on the end face of the bottle rim or on the seal make it impossible to seal the seal on the end face of the bottle neck.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur einfachen Herstellung eines Verschlusses anzugeben, der einfach im Aufbau ist und weitgehend unabhängig vom Aufschraubdrehmoment zuverlässig bei vorgegebenem Überdruck öffnet.The invention is based on the object of specifying a method for the simple manufacture of a closure which is simple in structure and opens reliably at a predetermined excess pressure largely independently of the screwing-on torque.

Die der Erfindung zugrundeliegende Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebene Lehre gelöst.The object on which the invention is based is achieved by the teaching specified in the characterizing part of claim 1.

Die Erfindung löst sich von dem bekannten Gedanken, die Dichtstrecke zu verkürzen oder das Dichtteil als Ganzes über ein elastisches Element gegen die Mündung des Flaschenhalses zu drücken. Grundgedanke der Erfindung ist es vielmehr, Dichtung, Anschlag und elastisches Element in einem Arbeitsgang zu schaffen.The invention frees itself from the known idea of shortening the sealing distance or pressing the sealing part as a whole against the mouth of the bottle neck via an elastic element. Rather, the basic idea of the invention is to create a seal, stop and elastic element in one operation.

Fig. 1 - 3 verdeutlichen verschiedene Verfahrensschritte bei der Durchführung des erfindungsgemäßen Verfahrens zur Herstellung eines Verschlusses gemäß der Erfindung. Zunächst wird in einen kappenförmigen Verschluß, bestehend aus Halteteil 16 und Dichtteil 17, das eben ist, eine ebenfalls ebene Dichtscheibe 18 eingelegt. Alles zusammen wird dann in Richtung eines Pfeiles 19 auf das Ende eines Flaschenhalses 20 aufgesetzt, wie das in Fig. 2 gezeigt ist. Danach wird ein Stempel 21 in Richtung eines Pfeiles 22 gegen das Dichtteil 17 gedrückt. In dem Stempel 21 befindet sich eine Vertiefung 23, aus der ein Vorsprung 24 vorsteht, der sich beim Andrücken des Stempels 21 in das Dichtteil 17 eindrückt und dort an voneinander entfernten Stellen Vertiefungen erzeugt, wie das aus Fig. 3 ersichtlich ist. Diese Vertiefungen stellen im Inneren der Verschlußkappe Vorsprünge 25 dar, die, da ihre Flächenausdehnung verhältnismäßig gering ist, die Dichtscheibe 18 sehr stark zusammendrücken, so daß die Vorsprünge 25 praktisch einen Anschlag bilden, der eine genaue Lage der Verschlußkappe in Bezug zu dem Stirnrand des Flaschenhalses 20 gewährleistet und damit auch die Zusammendrückung der Dichtscheibe 18 in diesen Umfangsbereichen. Diese definierte und durch die Anschläge reproduzierbare genaue Zusammenpressung in den Bereichen der Vorsprünge 25 bestimmt einen genau definierten Druck, bei dem Überdruck entweichen kann.1-3 illustrate various process steps when carrying out the method according to the invention for producing a closure according to the invention. First, a likewise flat sealing washer 18 is inserted into a cap-shaped closure, consisting of holding part 16 and sealing part 17, which is flat. Everything is then placed in the direction of an arrow 19 on the end of a bottle neck 20, as shown in FIG. 2. A stamp 21 is then in the direction of an arrow 22 pressed against the sealing part 17. In the stamp 21 there is a recess 23, from which a projection 24 protrudes, which presses into the sealing part 17 when the stamp 21 is pressed on and produces recesses there at distant locations, as can be seen from FIG. 3. These recesses represent in the interior of the cap protrusions 25, which, since their surface area is relatively small, compress the sealing disk 18 very strongly, so that the protrusions 25 practically form a stop, the exact position of the cap relative to the front edge of the bottle neck 20 guaranteed and thus also the compression of the sealing washer 18 in these circumferential areas. This defined compression which can be reproduced by the stops in the regions of the projections 25 determines a precisely defined pressure at which excess pressure can escape.

Bei der in Fig. 3 gezeigten Lage wird durch nicht dargestellte Mittel durch Andrücken von außen an das Halteteil 16 ein Gewinde 27 wie auch ein Kragen 28 erzeugt, der zum Sichtbarmachen des ersten Öffnens der Flasche dient.In the position shown in FIG. 3, a thread 27 as well as a collar 28 are produced by means not shown by pressing from the outside onto the holding part 16, which serves to make the first opening of the bottle visible.
