Description

Die Erfindung betrifft eine Verschlusskappe mit den Merkmalen des Oberbegriffs des unabhängigen Patentanspruchs. Solche Verschlüsse aus Kunststoff sind bekannt und werden zum Verschliessen unter anderem auch von Behältern mit kohlensäurehaltigen Getränke verwendet.The invention relates to a closure cap with the features the preamble of the independent claim. Such Plastic closures are known and are also used to close containers carbonated drinks used.

Dabei sind viele verschiedene Anordnungen zum Erzielen einer Dichtung zwischen der Verschlusskappe und der Behältermündung bekannt. Bei einer bekannten Dichtvariante wird die Dichtung mit einer an die Innenseite des Kappenbodens gelegten Dichtscheibe erzielt, die durch den Kappenboden gegen die Behältermündung angedrückt wird.There are many different arrangements for achieving one Seal between the cap and the container mouth known. In a known sealing variant, the seal with a sealing washer placed on the inside of the cap base achieved by the cap bottom against the container mouth is pressed.

Es ist wichtig, dass vor allem im Bereich des äusseren Randes der Behältermündung eine gute Anpressung der Dichtscheibe erzielt wird.It is important that especially in the area of the outer edge the container mouth a good pressure of the sealing washer is achieved.

Aus der EP 55 916 ist beispielsweise ein solcher Verschluss bekannt. Die Dichtscheibe wird durch einen Vorsprung im Bereich zwischen dem Kappenboden und der Kappenschürze gezielt gegen den oberen äusseren Rand der Mündung des Behälters gedrückt. Auf diese Weise wird eine Anpressung mit hohem Flächendruck und damit eine gute Dichtwirkung erzielt.Such a closure is, for example, from EP 55 916 known. The sealing washer is a protrusion in the Targeted area between the cap base and the cap apron against the upper outer edge of the mouth of the container pressed. In this way, a pressure is applied high surface pressure and thus a good sealing effect.

Wenn sich im Innern der Flasche ein überhöhter Druck bildet, beispielsweise durch Vergärung oder Erwärmung, besteht die Gefahr, dass der Behälter bricht oder dass die Verschlusskappe abspringt. Es wurden bereits verschiedene Versuche gemacht, dieses Problem zu lösen.If there is excessive pressure inside the bottle, for example by fermentation or heating, there is Danger of the container breaking or the cap jump off. Various attempts have already been made made to solve this problem.

Aus der EP 370 272 ist es beispielsweise bekannt, die umlaufende Rippe zum Andrücken der Dichtscheibe teilweise zu unterbrechen. Die Dichtscheibe kann im Bereich der Unterbrüche bei Überdruck ausweichen und so eine Reduktion des Druckes im Behälter erlauben. Die Konstruktion gemäss EP 370 272 ist aber mit dem Nachteil behaftet, dass in den Bereichen der Unterbrechung die Dichtscheibe überhaupt nicht an den äusseren Rand angedrückt wird. Dies kann zu Undichtheit führen, auch wenn im Behälter kein erhöhter Druck festzustellen ist.From EP 370 272 it is known, for example, that rotating Partially rib to press on the sealing washer interrupt. The sealing washer can be in the area of the interruptions avoid overpressure and thus a reduction of the Allow pressure in the container. The construction according to EP 370 272 has the disadvantage that in the areas the interruption do not touch the sealing washer at all outer edge is pressed. This can cause leakage lead even if there is no increased pressure in the container is.

Aus der US 4 629 083 (entspricht dem Oberbegriff des Anspruchs 1) und aus der EP 770 559 ist ausserdem eine Verschlusskappe bekannt, bei welcher der Wulst, welcher die Dichtscheibe gegen den Behälterhals drücken soll nicht als Verdickung im Übergangsbereich zwischen dem Kappenboden und der Kappenschürze angeordnet ist, sondern als axial nach unten hervorstehende, umlaufende Rippe. Bei dieser Konstruktion besteht das Problem, dass die Anpressung auf Grund des Spaltes zwischen der Rippe und der Innenseite der Kappenschürze nicht sehr stark ist. Diese beiden Konstruktionen lösen ausserdem das Problem des Berstens von Behältern bei erhöhtem Innendruck ebenfalls nicht.From US 4,629,083 (corresponds to the preamble of claim 1) and from EP 770 559 is also a cap is known in which the bead, which the sealing washer should not press against the neck of the container as a thickening in the transition area between the cap base and the cap apron is arranged, but as axially after protruding circumferential rib below. With this construction there is the problem that the pressure due to the Gaps between the rib and the inside of the cap apron is not very strong. These two constructions also solve the problem of container bursting increased internal pressure also not.

Es ist deshalb eine Aufgabe der vorliegenden Erfindung, die Nachteile des Bekannten zu vermeiden, insbesondere also eine Verschlusskappe zu schaffen, die bei erhöhtem Innendruck im Behälter in der Art eines Überdruckventils funktioniert, d.h. den Gasablass ermöglicht, die trotzdem bei normalem Innendruck zuverlässig dichtet und welche einfach und wirtschaftlich herstellbar ist.It is therefore an object of the present invention that To avoid disadvantages of the known, in particular one To create a sealing cap, which in the case of increased internal pressure Container in the manner of a pressure relief valve works, i.e. allows the gas release, which is still at normal internal pressure seals reliably and which is simple and economical can be produced.

Erfindungsgemäss werden diese Aufgaben bei der vorliegenden Verschlusskappe durch die Merkmale des kennzeichnenden Teils von Patentanspruch 1 gelöst.According to the invention, these tasks are in the present Cap by the characteristics of the characteristic part solved by claim 1.

Die Verschlusskappe für einen Behälter weist einen Kappenboden und eine Kappenschürze auf. Die Kappenschürze ist mit inneren Rückhaltemitteln versehen, welche mit äusseren Rückhaltemitteln an der Mündung eines Behälters in Eingriff bringbar sind. Die Kappe kann beispielsweise ein Schraubgewinde aber auch ein Schnapp- oder Bajonettgewinde aufweisen. Die Kappe ist vorteilhaft bei CO2-haltigen Getränken oder bei heiss abgefüllten Getränken einsetzbar.The cap for a container has a cap base and a cap apron. The cap apron is provided with inner retaining means, which can be brought into engagement with outer retaining means at the mouth of a container. The cap can have, for example, a screw thread or a snap or bayonet thread. The cap can be used advantageously for drinks containing CO 2 or for hot-filled drinks.

Die Verschlusskappe weist ausserdem eine Dichtscheibe, auf die wenigstens teilweise am Kappenboden anliegt. Selbstverständlich ist auch eine nichtdurchgehende Dichteinlage, beispielsweise ein Dichtring denkbar. Die Verschlusskappe weist ausserdem im Übergangsbereich zwischen dem Kappenboden und der Kappenschürze einen umlaufenden Wulst zum Anpressen der Dichtscheibe an die obere, äussere Kante der Mündung des Behälters auf. Die Verschlusskappe ist zwischen dem Wulst und der Schürze wenigstens teilweise mit einer umlaufenden Hinterschneidung versehen. Die Hinterschneidung kann sich gleichmässig über 360 Grad über den Umfang der Verschlusskappe erstrecken.The cap also has a sealing washer which lies at least partially on the cap base. Of course is also a non-continuous sealing insert, for example a sealing ring conceivable. The cap has also in the transition area between the cap base and the cap apron a circumferential bead for pressing the Sealing washer on the upper, outer edge of the mouth of the Container. The sealing cap is between the bead and the apron at least partially with a circumferential undercut Mistake. The undercut can be evenly over 360 degrees over the circumference of the closure cap extend.

Es ist aber auch denkbar die Hinterschneidung nur segmentweise auszubilden. Der Wulst ist ausserdem in wenigstens einen segmentförmigen Abschnitt mit einer Schwächung versehen. Die Kombination eines umlaufenden Wulstes mit einer Hinterschneidung und einer Schwächung in segmentartigen Abschnitten führt zu einer besonders guten Dichtwirkung, welche trotzdem das Ablassen eins Überdrucks erlaubt.However, the undercut is also conceivable only in segments train. The bead is also in at least one provide a segment-shaped section with a weakening. The Combination of a circumferential bead with an undercut and leads to a weakening in segment-like sections to a particularly good sealing effect, which nevertheless Relief of overpressure allowed.

Weil der Wulst umlaufend ohne Unterbrechungen im Übergangsbereich zwischen dem Kappenboden und der Kappenschürze ausgebildet ist, erfolgt eine gleichmässige Andrückung der Dichtscheibe an die Behältermündung. Die Hinterschneidung verleiht dem unteren Rand des Wulstes eine gewisse Flexibilität, sodass der Wulst bei Beaufschlagung mit Druck nach aussen biegbar ist. Durch die Wahl der Grösse der Hinterschneidung kann der Druck, bei welchem der Innendruck abgeblasen wird genau vorbestimmt werden. Die Schwächungen im Wulst verleihen dem Wulst in den vorbestimmten Abschnitten eine grössere radiale Flexibilität. In diesen Abschnitten kann die Dichtscheibe bei erhöhtem Innendruck nach aussen gedrückt werden. Ein Abblasen ist damit möglich.Because the bead runs all the way around in the transition area formed between the cap bottom and the cap apron the sealing washer is pressed on evenly to the container mouth. The undercut gives some flexibility at the bottom of the bead, so that the bead when pressure is applied to the outside is bendable. By choosing the size of the undercut can be the pressure at which the internal pressure is released be precisely predetermined. The weaknesses in the bead confer a larger one in the predetermined sections radial flexibility. In these sections, the sealing washer with increased internal pressure, be pushed outwards. A blow off is possible.

Bevorzugt erstreckt sich die Hinterschneidung vom unteren Rand des Wulstes in einen Bereich, der Abstand zum Kappenboden aufweist. Dies bedeutet, dass der Wulst im Übergangsbereich zwischen dem Kappenboden und der Kappenwand durchgehend ausgebildet ist.The undercut preferably extends from the lower one Edge of the bead in an area, the distance to the cap bottom having. This means that the bead is in the transition area continuous between the cap bottom and the cap wall is trained.

In einem besonders bevorzugten Ausführungsbeispiel ist die Schwächung des Wulstes durch Vertiefungen auf der Aussenseite des Wulstes gebildet, welche der Kappenschürze zugewandt ist. Damit werden segmentartige Schwächungen erzeugt, ohne dass sich eine unregelmässige Anpressfläche ergibt. Die Anpressfläche, welche die Dichtscheibe gegen den äusseren oberen Rand der Behältermündung anpresst erstreckt sich somit über 360 Grad und ist im wesentlichen flach, d.h. sie weist keine Vertiefungen oder Erhebungen auf. Die Vertiefungen auf der Aussenseite des Wulstes verleihen dem Wulst trotzdem in vorbestimmbaren Bereichen eine erhöhte radiale Flexibilität.In a particularly preferred embodiment, the Weakening of the bead due to depressions on the outside of the bead which faces the cap apron. This creates segment-like weakenings without there is an irregular contact surface. The contact surface, which the sealing washer against the outer upper Pressed on the edge of the container mouth thus extends over 360 degrees and is essentially flat, i.e. she has none Deepenings or elevations. The wells on the Outside of the bead still give the bead in predeterminable Areas increased radial flexibility.

Selbstverständlich ist es auch denkbar, andere Arten von Schwächungen vorzusehen. Beispielsweise kann der Wulst durch andere Materialwahl, andere Orientierung des Materials oder durch andere Dichte des Materials geschwächt werden.Of course, it is also conceivable to use other types of To provide for weakenings. For example, the bulge can pass through different choice of material, different orientation of the material or be weakened by different density of the material.

In einem alternativen Ausführungsbeispiel ist die Schwächung des Wulstes durch Vertiefungen gebildet, die sich vom unteren Ende des Wulstes axial gegen den Kappenboden erstrecken und die sich vorzugsweise über die ganze Dicke des Wulstes erstrecken. Weil sich die Vertiefungen nicht bis zum oberen Ende des Wulstes sondern nur gegen den Kappenboden hin erstrecken, werden die Nachteile eines Wulstes mit durchgehenden Untebrüchen gemäss Stand der Technik vermieden. In an alternative embodiment, the weakening is of the bead formed by depressions that extend from the lower Extend the end of the bead axially against the cap base and which preferably extend over the entire thickness of the bead. Because the depressions don't extend to the top End of the bead but only extend towards the base of the cap, the disadvantages of a bead with continuous Avoid interruptions according to the prior art.

Die Schwächung erstreckt sich vorteilhaft etwa über die Höhe der Hinterschneidung. Im Bereich zwischen dem unteren Ende des Wulstes und dem Ende der Hinterschneidung ist der Wulst flexibel. In diesem Bereich ist die Schwächung besonders wirkungsvoll.The weakening advantageously extends approximately over the height the undercut. In the area between the lower end of the bead and the end of the undercut is the bead flexible. The weakening is special in this area effective.

Die Abschnitte, welche Schwächungen des Wulstes aufweisen, umfassen vorzugsweise insgesamt (d.h. die Summe aller Abschnitte zusammen) einen Winkelbereich von 90° bis 220°. Dabei sind vorzugsweise etwa 3 bis 15 Abschnitte mit Schwächungen vorgesehen.The sections which have weakening of the bead preferably comprise in total (i.e. the sum of all sections together) an angular range of 90 ° to 220 °. There are preferably about 3 to 15 sections with weakenings intended.

Zur Erhöhung der Abblasfunktion kann der Kappenboden auf seiner Innenseite ausserdem mit wenigstens einer radialen Vertiefung versehen sein, die sich radial wenigsten über einen Dichtabschnitt des Kappenbodens erstreckt. Der Dichtabschnitt definiert diejenige Zone des Kappenbodens, welche die Dichtscheibe gegen die Behältermündung anpresst. Aufgrund der Vertiefung im Kappenboden kann die Dichtscheibe axial nach oben verdrängt werden und so einen Weg zum Abbau eines Überdrucks bilden. In einem besonders bevorzugten Ausführungsbeispiel fluchtet die radiale Vertiefung in radialer Dichtung mit einer Schwächung des Wulstes.The cap base can be opened to increase the blow-off function its inside also with at least one radial Be provided depression that radially least over extends a sealing portion of the cap bottom. The sealing section defines the zone of the cap base which presses the sealing washer against the container mouth. by virtue of the recess in the cap base can be the sealing washer be displaced axially upwards and thus a way to dismantle form an overpressure. In a particularly preferred one Embodiment aligns the radial recess in the radial Seal with a weakening of the bead.

In einem weiteren Ausführungsbeispiel ist der Kappenboden auf seiner Innenseite mit einer umlaufenden Rippe versehen, die konzentrisch zur Verschlusskappe verläuft. Die umlaufende Rippe dient zur Erhöhung des Anpressdruckes der Dichtscheibe. Ausserdem können auch radial verlaufende Rippen am Kappenboden vorgesehen sein. Die radialen Rippen sind vorzugsweise höher ausgebildet als die umlaufende Rippe. In diesem Fall wird auf die radialen Vertiefungen verzichtet. Es hat sich herausgestellt, dass das Vorsehen von solchen radialen Rippen vor allem bei Heissabfüllungen, beispielsweise bei Fruchtsäften, vorteilhaft ist. Aufgrund der Hitze wird dabei die Dichtscheibe weicher und es besteht üblicherweise die Gefahr, dass die Dichtscheibe radial nach innen gezogen wird. Mit den radialen Rippen und mit der umlaufenden Rippe wird dies vermieden.In a further exemplary embodiment, the cap base is open provided on the inside with a circumferential rib that runs concentrically to the cap. The circulating Rib serves to increase the contact pressure of the sealing washer. In addition, there can also be radial ribs on the cap base be provided. The radial ribs are preferred higher than the circumferential rib. In this case the radial depressions are dispensed with. It has found that the provision of such radial ribs especially with hot fillings, for example with fruit juices, is advantageous. Because of the heat, the Sealing washer softer and there is usually a risk of that the sealing washer is pulled radially inwards. With the radial ribs and with the circumferential rib this becomes avoided.

Die Innenseite 15 des Kappenbodens 2 ist ausserdem mit radialen Rippen 16 versehen. Die radialen Rippen 16 erstrecken sich wenigstens über den Dichtabschnitt 17, in welchem eine Dichtscheibe 5 (siehe Figur 1) gegen eine Behältermündung anpressbar ist. Der Kappenboden 2 ist ausserdem mit einer umlaufenden Rippe 23 versehen, welche die Anpressung der Dichtscheibe 5 im Bereich ausserhalb der radialen Vertiefungen 16 erhöht. Die Höhe h1 der radialen Rippen 16 ist grösser als die Höhe h2 der umlaufenden Rippe 23.The inside 15 of the cap base 2 is also provided with radial ribs 16. The radial ribs 16 extend at least over the sealing section 17, in which a sealing disk 5 (see FIG. 1) can be pressed against a container mouth. The cap base 2 is also provided with a circumferential rib 23 which increases the pressure on the sealing disk 5 in the area outside the radial recesses 16. The height h 1 of the radial ribs 16 is greater than the height h 2 of the circumferential rib 23.

In Figur 3 ist eine erfindungsgemässe Verschlusskappe ohne Dichtscheibe von unten gezeigt. Der umlaufende Wulst 6 weist eine durchgehende Innenseite auf. Auf der Aussenseite 13 des Wulstes 6, welche gegen die Kappenschürze 3 gerichtet ist, ist der Wulst 6 mit Vertiefungen 12 versehen. Die Vertiefungen 12 führen zu Schwächungen des Wulstes 6 in segmentartigen Abschnitten 9. Die Vertiefungen 12 sind gleichmässig über den gesamten Umfang der Verschlusskappe verteilt. Sie erstrecken sich je über einen Winkelbereich von etwa 5° bis 40°. Ausserdem sind radiale Rippen 16 im Kappenboden 2 gezeigt, welche zwischen den Vertiefungen 12 enden. Auf der Innenseite des Kappenbodens 2 ist ausserdem eine umlaufende Rippe 23 gezeigt, welche im Dichtabschnitt 17 die nicht dargestellte Dichtscheibe 5 gegen die Behältermündung anpresst. Die Hinterschneidung 8 zwischen der Kappenschürze 3 und dem Wulst 6 verleiht dem Wulst 6 in Kombination mit den Vertiefungen 12 eine erhöhte Flexibilität in Pfeilrichtung r.A closure cap according to the invention is shown in FIG Sealing washer shown from below. The circumferential bead 6 has a continuous inside. On the outside 13 of the Beads 6, which is directed against the cap apron 3, the bead 6 is provided with depressions 12. The wells 12 lead to weakening of the bead 6 in segment-like Sections 9. The depressions 12 are even over the distributed over the entire circumference of the closure cap. They extend each over an angular range of approximately 5 ° to 40 °. Furthermore radial ribs 16 are shown in the cap base 2, which end between the wells 12. On the inside of the cap base 2 is also shown a circumferential rib 23, which in the sealing section 17, the not shown Press the sealing disk 5 against the container mouth. The undercut 8 between the cap apron 3 and the bead 6 gives the bead 6 in combination with the depressions 12 increased flexibility in the direction of the arrow r.

In Figuren 4a und 4b sind verschiedene Ausführungsbeispiele zur Ausbildung der Schwächungen 10 des Wulstes 6 gezeigt.Various exemplary embodiments are shown in FIGS. 4a and 4b shown to form the weakenings 10 of the bead 6.

In Figur 4a ist der Wulst 6 nur auf der Aussenseite 13, welche gegen die Kappenschürze 2 gerichtet ist, mit einer Vertiefung 12 versehen. Die Vertiefung 12 erstreckt sich vom unteren Ende 14 axial gegen den Kappenboden 2 hin. Die Hinterschneidung 8 weist eine Höhe h auf. Das Ende der Hinterschneidung 8 liegt im Abstand zu der Innenseite 15 des Kappenbodens 2. Dies heisst, dass der Wulst 6 im Übergangsbereich 7 zwischen der Kappenschürze 2 und dem Kappenboden 3 zwischen Kappenboden und Kappenschürze durchgehend ausgebildet ist. Die Dichtscheibe 5 wird durch den Wulst 6 gegen eine nur schematisch dargestellte Mündung eines Behälters 20 gedrückt.In FIG. 4a, the bead 6 is only on the outside 13, which is directed against the cap apron 2, with a Provide depression 12. The recess 12 extends from lower end 14 axially against the cap base 2. The undercut 8 has a height h. The end of the undercut 8 is at a distance from the inside 15 of the cap base 2. This means that the bead 6 in the transition area 7 between the cap apron 2 and the cap base 3 continuously formed between the cap base and the apron is. The sealing washer 5 is against a by the bead 6 mouth of a container 20 only shown schematically pressed.

In Figur 4b ist ein alternatives Ausführungsbeispiel der Erfindung gezeigt. Die Vertiefung 12', welche die Schwächung 10 im Wulst 6 bildet ist in radialer Richtung durchgehend ausgebildet. Ansonsten entspricht das Ausführungsbeispiel gemäss Figur 4b dem Beispiel aus Figur 4a.FIG. 4b shows an alternative embodiment of the Invention shown. The recess 12 ', which is the weakening 10 in the bead 6 is continuous in the radial direction educated. Otherwise the embodiment corresponds according to FIG. 4b the example from FIG. 4a.

In Figur 5 ist das Ausführungsbeispiel gemäss Figur 4a auf einen Behälter mit erhöhtem Innendruck gezeigt. Auf Grund des erhöhten Innendrucks im Behälter 20 ist der Kappenboden 2 axial nach aussen gewölbt (sogenanntes Doming). Dadurch wird die Dichtscheibe 5 im Dichtabschnitt 17 druckentlastet, so dass Gas entweichen kann. Aufgrund der Schwächung 10 des Wulstes 6 kann der Wulst und damit die Dichtscheibe 5 in Pfeilrichtung r radial nach aussen gedrückt werden, wodurch Gas auch in diesem Bereich entweichen kann. In gestrichelten Linien ist die Position des Wulstes in Normallage gezeigt. In den Umfangabschnitten ausserhalb der Abschnitte 9 mit Schwächungen 10 nimmt der Wulst 6 diese Originallage ein. Die Entlüftung erfolgt also nur segmentweise und ist daher genau kontrollierbar. In den übrigen Abschnitten ist die Anpressung der Dichtscheibe 5 nach wie vor so gross, dass eine Dichtung gewährleistet ist.FIG. 5 shows the exemplary embodiment according to FIG. 4a shown a container with increased internal pressure. Because of the the cap bottom 2 is increased internal pressure in the container 20 axially curved outwards (so-called doming). This will the sealing washer 5 is relieved of pressure in the sealing section 17, so that gas can escape. Because of the weakening 10 of the bead 6 can the bead and thus the sealing washer 5 in the direction of the arrow r be pushed radially outwards, causing gas can also escape in this area. In dashed lines The position of the bead in normal position is shown by lines. In the circumferential sections outside the sections 9 with weakenings 10 the bulge 6 assumes this original position. The Venting therefore only takes place in segments and is therefore precise controllable. In the remaining sections there is the contact pressure the sealing disc 5 is still so large that a seal is guaranteed.
