Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Dosendeckels mit einem Deckelring mit einem ringfƶrmigen Siegelflansch und einer auf den Siegelflansch gesiegelten und von diesem peelbaren Verschlussmembran, wobei der Siegelflansch mit einem inneren Rand eine senkrecht zu einer Deckelringachse liegende, eine Deckelebene definierende ƖffnungsquerschnittsflƤche als Entnahmeƶffnung begrenzt und mit einem Ƥusseren Rand in eine im wesentlichen senkrecht zur Deckelebene liegende Ringwand Ć¼bergeht, deren freies Ende zu einem Aussenbƶrdel zum Verbinden des Dosendeckels mit dem Ɩffnungsrand eines Dosenkƶrpers geformt ist, und wobei der Siegelflansch mit der Deckelebene einen spitzen Winkel einschliesst und die Verschlussmembran Ć¼ber der Entnahmeƶffnung gewƶlbt ist, wobei die Wƶlbung der Verschlussmembran durch die Entnahmeƶffnung hindurch zwischen zwei im wesentlichen spiegelsymmetrisch zur ƖffnungsquerschnittsflƤche liegenden Endpositionen verschiebbar ist.The invention relates to a method for producing a can lid with a cover ring with an annular sealing flange and sealed on the sealing flange and peelable from this closure membrane, the sealing flange with an inner edge a perpendicular to a lid ring axis lying, defining a lid plane opening cross-sectional area as a discharge opening and merges with an outer edge in a substantially perpendicular to the lid plane annular wall whose free end is formed into an outer crimp for connecting the can lid with the opening edge of a can body, and wherein the sealing flange with the lid plane forms an acute angle and the sealing membrane over the removal opening is curved, wherein the curvature of the closure membrane through the removal opening between two substantially mirror-symmetrical lying to the opening cross-sectional area end positions is displaceable.

Bei bekannten Dosendeckeln mit einem Deckelring und auf diesem angeordneter Verschlussmembran erstreckt sich die Entnahmeƶffnung bis in die NƤhe des Bƶrdelrandes, so dass nach dem Entfernen der Verschlussmembran nur eine schmale, vom Bƶrdelrand radial nach innen abragende RingflƤche verbleibt. Nach dem Entfernen der Verschlussmembran, die in den meisten FƤllen als Aufreissfolie ausgestaltet ist, wird nach dem Abziehen (Peelen) der Verschlussmembran, Ƥhnlich wie bei einem Vollaufreissdeckel, eine verhƤltnismƤssig grosse BehƤlterƶffnung geschaffen, wodurch das FĆ¼llgut leicht zugƤnglich wird. Ein weiterer Vorteil dieses Deckelsystems liegt darin, dass das FĆ¼llgut sterilisiert werden kann.In known can lids with a cover ring and arranged on this sealing membrane, the removal opening extends into the vicinity of the flanged edge, so that after removal of the sealing membrane only a narrow, from the bead radially projecting inwardly annular surface remains. After removing the sealing membrane, which is designed in most cases as a tear-open, after peeling (peeling) of the closure membrane, similar to a full rip open, created a relatively large container opening, whereby the contents is easily accessible. Another advantage of this cover system is that the contents can be sterilized.

Bei einem aus der EP-A-1 153 840 bekannten Verfahren zur Herstellung eines Deckelringes fĆ¼r einen Dosendeckel mit Verschlussmembran wird zunƤchst ein ebenes Blechteil zu einem zylinderischen Rohr umgeformt. Die axial verlaufenden RƤnder des Rohres werden zusammengepresst und miteinander verschweisst, was mittels eines Laserstrahls erfolgt und zur Bildung einer Stumpfstossschweissnaht fĆ¼hrt. Das Rohr wird sodann in gleich lange Rohrabschnitte bzw. zylinderfƶrmige Ringe unterteilt. Jeder zylinderfƶrmige Ring wird zu einem Deckelring mit einem Bƶrdelrand zur Befestigung auf einem Dosenrumpf und zu einer ringfƶrmigen AuflageflƤche fĆ¼r die spƤtere Festlegung der Verschlussmembran umgeformt.At one of the EP-A-1 153 840 known method for producing a cover ring for a can lid with closure membrane, a flat sheet metal part is first formed into a cylindrical tube. The axially extending edges of the tube are pressed together and welded together, which is done by means of a laser beam and leads to the formation of a butt weld seam. The tube is then divided into equal length tube sections or cylindrical rings. Each cylindrical ring is formed into a lid ring having a crimp rim for attachment to a can body and to an annular support surface for later attachment of the closure membrane.

Das vorstehend erwƤhnte Verfahren zur Herstellung eines Deckelringes ausgehend von einem zylinderfƶrmigen Ring hat gegenĆ¼ber der klassischen Deckelringherstellung, bei welcher zunƤchst eine Blechscheibe umgeformt und anschliessend zur Bildung des Deckelringes die Entnahmeƶffnung ausgestanzt wird, den Vorteil eines erheblich verminderten Schrottanteils.The above-mentioned method for producing a cover ring starting from a cylindrical ring has the advantage of a significantly reduced scrap fraction compared to the classic cover ring manufacturing, in which initially formed a sheet metal disc and then punched out to form the cover ring removal opening.

Bei herkƶmmlichen Dosendeckeln mit einem Deckelring mit einem Siegelflansch und auf diesem angeordneter Verschlussmembran liegen Siegelflansch und Verschlussmembran Ć¼blicherweise in einer senkrecht zu einer Deckelringachse liegenden Deckelebene.In conventional can lids with a lid ring with a sealing flange and arranged on this sealing membrane sealing flange and sealing membrane are usually in a lying perpendicular to a cover ring axis cover level.

Ein wesentlicher Nachteil herkƶmmlicher Deckelringe mit peelbarer Verschlussmembran liegt darin, dass Dosen mit derartigen Dosendeckeln nur mit gesteuertem Gegendruck sterilisiert werden kƶnnen. Der Anwendungsbereich herkƶmmlicher Deckelringe mit peelbarer Verschlussmembran wird dadurch insbesondere im bedeutenden Markt der Dosen fĆ¼r Lebensmittel stark eingeschrƤnkt.A major disadvantage of conventional cover rings with peelable sealing membrane is that cans can be sterilized with such can lids only with controlled back pressure. The field of application of conventional cover rings with peelable sealing membrane is thereby severely limited, in particular in the important market of cans for food.

Aus der WO-A-2005/005277 und der DE-A-103 38 445 sind Dosendeckel mit einem Deckelring bekannt, bei denen der Siegelflansch mit der Deckelebene einen spitzen Winkel einschliesst und die Verschlussmembran Ć¼ber der Entnahmeƶffnung gewƶlbt ist. Bei der Herstellung dieser Dosendeckel wird die Verschlussmembran auf den vorgƤngig gegenĆ¼ber der Deckelebene bereits schrƤggestellten Siegelflansch aufgesiegelt.From the WO-A-2005/005277 and the DE-A-103 38 445 Can lids are known with a cover ring, in which the sealing flange with the lid plane encloses an acute angle and the sealing membrane over the removal opening is arched. During the production of these can ends, the sealing membrane is sealed onto the sealing flange, which has previously been inclined in relation to the cover plane.

Der Erfindung liegt die Aufgabe zugrunde, ein zum Verfahren der eingangs genannten Art alternatives Verfahren anzugeben, welches mit einfachen Mitteln kostengĆ¼nstig realisiert werden kann.The invention has for its object to provide an alternative to the method of the type mentioned method, which can be realized inexpensively by simple means.

Zur erfindungsgemƤssen Lƶsung der Aufgabe fĆ¼hrt, dass eine Verschlussmembran auf einen Deckelring mit einem in der Deckelebene liegenden Siegelflansch gesiegelt wird, der Deckelring mit aufgesiegelter Verschlussmembran so angestellt wird, dass er mit der Deckelebene einen spitzen Winkel einschliesst, und die Verschlussmembran durch die Entnahmeƶffnung hindurch tiefgezogen wird.To achieve the object according to the invention, a closure membrane is sealed onto a cover ring with a sealing flange located in the cover plane, the cover ring with sealed closure membrane is adjusted such that it encloses an acute angle with the cover plane, and the closure membrane is deep-drawn through the removal opening becomes.

Bevorzugt schliesst eine an die gewƶlbte Verschlussmembran beim Ɯbergang der Wƶlbung in den Siegelflansch am inneren Rand angelegte Tangente in einer der Endpositionen mit der Deckelebene einen spitzen Winkel Ī² ein, der kleiner oder gleich dem Winkel Ī± zwischen Siegelflansch und Deckelebene ist.Preferably, a tangent applied to the curved sealing membrane at the transition of the curvature into the sealing flange at the inner edge encloses an acute angle Ī² in one of the end positions with the cover plane which is smaller than or equal to the angle Ī± between sealing flange and cover plane.

ZweckmƤssigerweise liegt die Wƶlbung der Verschlussmembran in beiden Endpositionen innerhalb einer durch die Hƶhe der Ringwand vorgegebenen Kemtiefe.Conveniently, the curvature of the closure membrane is in both end positions within a given by the height of the annular wall Kemtiefe.

Der Winkel Ī± zwischen Siegelflansch und Deckelebene betrƤgt vorzugsweise 10Ā° bis 60Ā°. Ebenso betrƤgt der Winkel Ī² zwischen der an die gewƶlbte Verschlussmembran beim Ɯbergang der Wƶlbung in den Siegelflansch am inneren Rand angelegten Tangente und der Deckelebene vorzugsweise 10Ā° bis 60Ā°.The angle Ī± between the sealing flange and the cover plane is preferably 10 Ā° to 60 Ā°. Similarly, the angle Ī² between the tangent to the curved sealing membrane at the transition of the curvature into the sealing flange at the inner edge and the cover plane is preferably 10 Ā° to 60 Ā°.

Die Verschlussmembran ist bevorzugt eine durch Tiefziehen verformbare, zweckmƤssigerweise durch Peelen vom Siegelflansch lƶsbare Aluminiumfolie oder Aluminium/Kunststoff-Verbundfolie.The closure membrane is preferably a deformable by deep drawing, conveniently by peeling from the sealing flange detachable aluminum foil or aluminum / plastic composite film.

Als Werkstoff fĆ¼r den Deckelring eignen sich alle zur Dosenherstellung bekannten Metalle wie Aluminium, Stahl oder Weissblech. Diese Metalle kƶnnen auch lackiert oder mit einer Kunststoffbeschichtung aus beispielsweise Polypropylen umgeformt werden.As a material for the cover ring are all known for can production metals such as aluminum, steel or tinplate. These metals can also be painted or reshaped with a plastic coating of, for example, polypropylene.

Der mit dem erfindungsgemƤssen Verfahren hergestellte Dosendeckel eignet sich insbesondere als Verschluss fĆ¼r Dosen mit sterilisierbarem FĆ¼llgut.The can lid produced by the method according to the invention is particularly suitable as a closure for cans with sterilizable filling material.

Ein in Fig. 1 dargestellter Deckel 10' mit einem rotationssymmetrisch zu einer Ringachse z liegenden Deckelring 11' weist einen in einer rechtwinkelig zur Ringachse z stehenden Deckelebene E angeordneten kreisringfƶrmigen Siegelflansch 12 auf. Der Ƥussere Rand des Siegelflansches 12 geht in eine im wesentlichen konzentrisch zur Ringachse z liegende Ringwand 18 Ć¼ber. Das freie Ende der Ringwand 18 ist zu einem Aussenbƶrdel 20 geformt. Der Abstand zwischen Deckelebene E und Aussenbƶrdel 20 wird als Kemtiefe t bezeichnet. Der innere Rand des Siegelflansches 12 ist zu einem Rollrand 22 eingerollt und begrenzt eine Entnahmeƶffnung 24 mit einer kreisfƶrmigen ƖffnungsquerschnittsflƤche F.An in Fig. 1 illustrated cover 10 'with a rotationally symmetrical to a ring axis Z lying lid ring 11' has a in a right angle to Ring axis z standing lid plane E arranged annular sealing flange 12. The outer edge of the sealing flange 12 merges into an annular wall 18 which is substantially concentric with the ring axis z. The free end of the annular wall 18 is formed into an outer flange 20. The distance between the cover plane E and outer flange 20 is referred to as Kemtiefe t. The inner edge of the sealing flange 12 is rolled into a rolled edge 22 and defines a removal opening 24 with a circular opening cross-sectional area F.

Auf den Siegelflansch 12 ist eine die Entnahmeƶffnung 24 verschliessende Verschlussmembran 14 gesiegelt. Die Verschlussmembran 14 liegt dem Siegelflansch 12 auf und ist mit diesem Ć¼ber eine Klebstoff- oder Siegelschicht verbunden. Als Material fĆ¼r die Verschlussmembran 14 dient beispielsweise eine gegebenenfalls eine heisssiegelfƤhige Beschichtung aufweisende Folie aus Aluminium oder aus Stahlblech. Die Siegelung zwischen Verschlussmembran 14 und Siegelflansch 12 wird so eingestellt, dass die Verschlussmembran vom Siegelflansch durch Abziehen (Peelen) entfernt werden kann. Eine am Rand der Verschlussmembran 14 angeordnete Aufreisslasche 16 dient zum Abziehen oder Peelen der Verschlussmembran 14 vom Siegelflansch 12 unter Freigabe der Entnahmeƶffnung 24.On the sealing flange 12, a closure membrane 14 closing the removal opening 24 is sealed. The closure membrane 14 rests against the sealing flange 12 and is connected thereto via an adhesive or sealing layer. The material used for the closure membrane 14 is, for example, an aluminum or sheet-steel foil optionally having a heat-sealable coating. The seal between sealing membrane 14 and sealing flange 12 is adjusted so that the sealing membrane from the sealing flange by peeling (peeling) can be removed. A tear-open tab 16 arranged on the edge of the closure membrane 14 serves to remove or peel the closure membrane 14 from the sealing flange 12, releasing the removal opening 24.

Ein in Fig. 2 gezeigter Deckel 10 mit einem Deckelring 11 unterscheidet sich vom Deckel 10' mit einem Deckelring 11' nach dem Stand der Technik durch die folgenden Merkmale:

  • Der Siegelflansch 12 schliesst mit der Deckelebene E einen spitzen Winkel Ī± ein.
  • Die Verschlussmembran 14 ist Ć¼ber der durch den inneren Rollrand 22 des Siegelflansches 12 definierten ƖffnungsquerschnittsflƤche F kugelfƶrmig gewƶlbt und durch die Entnahmeƶffnung 24 hindurch zwischen den beiden im wesentlichen spiegelsymmetrisch zur ƖffnungsquerschnittsflƤche F liegenden Endpositionen A und B verschiebbar.
  • Die in der Endposition B beim Ɯbergang der Wƶlbung in den Siegelflansch 12 am inneren Rand 22 an die gewƶlbte Verschlussmembran 14 angelegte Tangente m schliesst mit der Deckelebene E einen spitzen Winkel Ī² ein, der kleiner oder gleich dem Winkel Ī± zwischen Siegelflansch 12 und Deckelebene E ist.
An in Fig. 2 shown lid 10 with a lid ring 11 differs from the lid 10 'with a lid ring 11' according to the prior art by the following features:
  • The sealing flange 12 encloses an acute angle Ī± with the cover plane E.
  • The closure membrane 14 is spherically curved over the opening cross-sectional area F defined by the inner rolled edge 22 of the sealing flange 12 and lying through the removal opening 24 between the two substantially mirror-symmetrical to the opening cross-sectional area F. End positions A and B are displaceable.
  • The in the final position B at the transition of the curvature in the sealing flange 12 at the inner edge 22 to the curved closure membrane 14 applied tangent m includes the cover plane E an acute angle Ī², which is smaller than or equal to the angle Ī± between the sealing flange 12 and cover level E. ,

Zur Herstellung des Dosendeckels 10 wird zunƤchst in bekannter Art ein Deckelring 11' hergestellt und eine Verschlussmembran 14 auf den in der Deckelebene E liegenden Siegelflansch 12 gesiegelt. Anschliessend wird gemƤss Fig. 6 der Deckelring 11' mit aufgesiegelter Verschlussmembran 14 in ein erstes Werkzeug 40 eingespannt. Mit einem zweiten Werkzeug 42 wird der Siegelflansch 12 zur gewĆ¼nschten angewinkelten Position aufgestellt. Mit einem dritten Werkzeug 44, z. B. mit einem kugelfƶrmigen Stempel aus Teflon, wird die Verschlussmembran 14 durch Tiefziehen in der Ringachse z zu einer Wƶlbung mit einer Wƶlbhƶhe s umgeformt. Anstelle eines mechanischen Tiefzuges mit einem Stempel kann die Verformung auch pneumatisch oder hydraulisch erfolgen.To produce the can lid 10, a lid ring 11 'is first produced in a known manner and a closure membrane 14 is sealed onto the sealing flange 12 located in the lid plane E. Subsequently, according to Fig. 6 the lid ring 11 'clamped with sealed closure membrane 14 in a first tool 40. With a second tool 42, the sealing flange 12 is set to the desired angled position. With a third tool 44, z. B. with a spherical punch made of Teflon, the closure membrane 14 is formed by deep drawing in the ring axis z to a curvature with a camber s. Instead of a mechanical deep drawing with a stamp, the deformation can also be done pneumatically or hydraulically.

Beim Tiefziehen der Wƶlbung wird darauf geachtet, dass Wƶlbhƶhe Ā± s der Verschlussmembran 14 so bemessen ist, dass die Verschlussmembran 14 in ihren Endstellungen A und B vollstƤndig innerhalb des durch die grosse Kemtiefe t vorgegebenen hohen Dosenrandes liegt. Mit einer grossen Kemtiefe wird auch das bei Deckelringen mit geringer Kemtiefe auftretende Problem der aufstehenden Aufreisslasche gelƶst. Durch den hohen Dosenrand bleibt die Lasche geschĆ¼tzt und kann in AbfĆ¼llanlagen und bei Transportprozessen nicht hƤngen bleiben. Die ist insbesondere bei Verwendung von Laminaten mit schlechten Deadfold-Eigenschaften von Bedeutung.During the deep drawing of the curvature, care is taken that the curvature height Ā± s of the closure membrane 14 is dimensioned so that the closure membrane 14 lies completely in its end positions A and B within the high can edge predetermined by the large core depth t. With a large Kemtiefe and the problem occurring in lid rings with low Kemtiefe the rising tear-open is solved. Due to the high edge of the can, the flap remains protected and can not get caught in filling lines and transport processes. This is especially important when using laminates with poor deadfold properties.

GrundsƤtzlich kann der Tiefziehschritt in beiden Richtungen durchgefĆ¼hrt werden, da die gewƶlbte Verschlussmembran 14 zwischen der Endposition A und der im wesentlichen spiegelsymmetrisch zur Entnahmeƶffnung 24 liegenden Endposition B innerhalb des durch die Ringwand 18 bzw. des sich daraus ergebenden hohen Dosenrandes definierten Innenraumes verschiebbar ist. Bevorzugt erfolgt jedoch der Tiefziehschritt in die Endposition A. Der Tiefziehschritt kann auch vor dem Aufstellen des Siegelflansches 12 in die angewinkelte Position erfolgen.Basically, the deep drawing step can be carried out in both directions, since the curved closure membrane 14 between the end position A and the lying in substantially mirror-symmetrical to the removal opening 24 end position B within the defined by the annular wall 18 and the resulting high dose edge interior space is displaceable. Preferably, however, the deep-drawing step takes place in the end position A. The deep-drawing step can also take place before the sealing flange 12 is set up in the angled position.

Die Funktion der gewƶlbten Verschlussmembran 14 wird nachfolgend anhand der Fig. 2 bis 5 nƤher erlƤutert.The function of the curved closure membrane 14 is described below with reference to Fig. 2 to 5 explained in more detail.

Nach dem EinfĆ¼llen eines heissen, flĆ¼ssigen oder flĆ¼ssig/festen FĆ¼llgutes 32 in einen Dosenkƶrper 30 wird der Deckelring 11 mit der aufgesiegelten Verschlussmembran 14 in Endstellung A auf den Dosenkƶrper 30 aufgesetzt, Ć¼berfĆ¼lltes FĆ¼llgut 32 wird zwischen dem Aussenbƶrdel 20 des Deckelringes 11 und dem Rand des Dosenkƶrpers 30 ausgequetscht, und der Deckelring 11 wird unter Herstellung eines dichten Dosenverschlusses auf den Dosenkƶrper 30 aufgebƶrdelt.After filling a hot, liquid or liquid / solid filling material 32 in a can body 30 of the lid ring 11 is placed with the sealed closure membrane 14 in the end position A on the can body 30, overfilled product 32 is between the outer flanges 20 of the lid ring 11 and the edge of the Can body 30 squeezed out, and the lid ring 11 is crimped to produce a dense dose seal on the can body 30.

Beim nachfolgenden Sterilisieren des FĆ¼llgutes 32 in der verschlossenen Dose nimmt das FĆ¼llgutvolumen als Folge der erhƶhten Temperatur zu. Gleichzeitig steigt der Innendruck als Folge eines erhƶhten Dampfdrucks der FĆ¼llgutflĆ¼ssigkeit bei der Sterilisiertemperatur gegenĆ¼ber dem Dampfdruck bei der EinfĆ¼lltemperatur um einem Betrag +Ī”P an. Die Verschlussmembran 14 wird aus der anfƤnglichen unteren Endposition A durch die Entnahmeƶffnung 24 hindurch in die obere Endposition B gedrĆ¼ckt und steht in dieser Position unter einem gegenĆ¼ber AtmosphƤrendruck erhƶhten Innendruck. Da die beim Ɯbergang der Wƶlbung in den Siegelflansch 12 am inneren Rand 22 in der Endpositionen B an die gewƶlbte Verschlussmembran 14 angelegte Tangente m mit der Deckelebene E einen spitzen Winkel Ī² einschliesst, der kleiner oder gleich dem Winkel Ī± zwischen Siegelflansch 12 und Deckelebene E ist, wird die Siegelverbindung zwischen Verschlussmembran 14 und Siegelflansch 12 auf ScherkrƤfte beansprucht, die wesentlich grƶsser sind als die KrƤfte, die durch den beim Sterilisieren auftretenden maximalen Doseninnendruck auf die Siegelverbindung einwirken. Einer allfƤlligen plastischen Verformung der Verschlussmembran 14 kann beispielsweise mit einem dickeren Membranmaterial, mit StĆ¼tzfolien aus beispielsweise orientiertem Polyamid (oPA),orientiertem Polyethylenterephthalat (oPET), orientiertem Polypropylen (oPP) oder mit einem faserverstƤrkten Kunststofffilm entgegengewirkt werden.During the subsequent sterilization of the contents 32 in the sealed can, the volume of the contents increases as a result of the increased temperature. At the same time, as a result of an increased vapor pressure of the filling liquid at the sterilizing temperature, the internal pressure increases by an amount + Ī”P relative to the vapor pressure at the filling temperature. The closure membrane 14 is pushed from the initial lower end position A through the discharge opening 24 into the upper end position B and is in this position under an increased relative to atmospheric pressure internal pressure. Since at the transition of the curvature in the sealing flange 12 at the inner edge 22 in the end positions B to the curved closure membrane 14 applied tangent m with the lid plane E includes an acute angle Ī², which is smaller than or equal to the angle Ī± between the sealing flange 12 and lid level E. , the sealing connection between closure membrane 14 and sealing flange 12 is subjected to shear forces which are substantially greater than the forces caused by sterilization occurring maximum dose pressure on the sealing compound act. A possible plastic deformation of the closure membrane 14 can be counteracted, for example, with a thicker membrane material, with support foils of, for example, oriented polyamide (oPA), oriented polyethylene terephthalate (oPET), oriented polypropylene (oPP) or with a fiber-reinforced plastic film.

Beim AbkĆ¼hlen der Dose auf Raumtemperatur nimmt das FĆ¼llgutvolumen als Folge der sinkenden Temperatur wieder ab. Gleichzeitig sinkt der Innendruck als Folge des nun erniedrigten Dampfdrucks der FĆ¼llgutflĆ¼ssigkeit bei der Sterilisiertemperatur gegenĆ¼ber dem Dampfdruck bei der EinfĆ¼lltemperatur um einem Betrag -Ī”P. Die Verschlussmembran 14 wird aus der oberen Endposition B durch die Entnahmeƶffnung hindurch in die untere Endposition A gezogen und steht in dieser Position unter einem gegenĆ¼ber AtmosphƤrendruck erniedrigten Innendruck. Dabei kann sich der Winkel Ī± zwischen Siegelflansch 12 und Deckelebene E verkleinern und hƤlt durch die entstehenden RĆ¼ckstellkrƤfte die Verschlussmembran 14 unter Spannung und demzufolge quasi faltenfrei.When the can is cooled down to room temperature, the volume of the contents decreases as a result of the falling temperature. At the same time, the internal pressure drops as a result of the now reduced vapor pressure of the filling liquid at the sterilizing temperature compared to the vapor pressure at the filling temperature by an amount -Ī”P. The closure membrane 14 is pulled from the upper end position B through the removal opening into the lower end position A and is in this position under an atmospheric pressure reduced to the internal pressure. In this case, the angle Ī± between sealing flange 12 and cover level E can be reduced and holds the closing membrane 14 under tension and thus virtually without wrinkles due to the resulting restoring forces.
