Description

Die Erfindung betrifft ein Verfahren zum Entlüften einer mittels eines elastischen Stopfens verschlossenen, gefüllten Flasche. Die Erfindung betrifft ferner eine Vorrichtung zum Entlüften einer mittels eines solchen Stopfens verschlossenen Flasche.The invention relates to a method for venting a filled bottle closed by means of an elastic plug. The invention further relates to a device for venting a closed by means of such a plug bottle.

Bevorzugtes Einsatzgebiet der vorliegenden Erfindung sind kleine Flaschen, solche, die zum Abfüllen von Arzneimitteln Verwendung finden, sogenannte Vials.Preferred fields of use of the present invention are small bottles, such as those used for filling medicaments, so-called vials.

Beim Aufsetzen von Stopfen auf Flaschen mit einer hohen Füllung bildet sich ein Luftüberdruck in den Flaschen. Dieser Überdruck drückt auf dem Weg zwischen einem Stopfenaufsetzer und einer Bördelstation die Stopfen wieder aus den Flaschen. Diese liegen infolgedessen lose auf den Flaschen. Durch Erschütterungen bei dem Flaschentransport fallen Stopfen in die Abfüll- und Verpackungsmaschine und verursachen dort zahlreiche Folgestörungen. Außerdem besteht die Gefahr der Unsterilität des Produkts. Nachdrückstationen, ob mit einem Stößel oder mit einer Rolle, oder aber Zwangsführungen sind fast wirkungslos und bergen sogar neue Gefahren. Manche Stopfen können von Hand oftmals in die Flaschen gedrückt werden und werden dennoch wieder aus den Flaschen gedrückt.When placing stoppers on bottles with a high filling, an air pressure builds up in the bottles. This overpressure pushes the plugs out of the bottles on the way between a plug applicator and a crimping station. These are consequently loose on the bottles. Shakes in the transport of bottles cause plugs to fall into the filling and packaging machine and cause numerous consequential problems there. There is also the risk of the product becoming sterile. Repressing stations, whether with a pestle or with a roller, or forced guidance systems are almost ineffective and even harbor new dangers. Some plugs can often be pushed into the bottles by hand and are nevertheless pushed out of the bottles again.

Die elastischen Stopfen sind beispielsweise mit einem Ansatz verbunden, dessen Durchmesser größer ist als der Durchmesser des in die Flaschenöffnung eingesteckten Stopfenabschnittes. In vollständig in die Flaschenöffnung eingesteckter Position des Stopfens liegt der Ansatz an der Flasche an.The elastic plugs are connected, for example, to a lug whose diameter is greater than the diameter of the plug-in portion inserted into the bottle opening. In fully inserted into the bottle opening position of the plug, the approach is on the bottle.

Ein Verfahren zum Verpacken eines druckempfindlichen Produktes ist aus US 5 519 984 bekannt.A method of packaging a pressure sensitive product is known from US 5 519 984.

Es ist Aufgabe der vorliegenden Erfindung, ein Verfahren zum Entlüften einer mittels eines Stopfens verschlossenen Flasche anzugeben, bei dem gewährleistet ist, dass der in die Flasche eingesteckte Stopfen nicht durch Überdruck aus der Flasche herausgedrückt wird.It is an object of the present invention to provide a method for venting a closed by a stopper bottle, which ensures that the plugged into the bottle plug is not pushed out of the bottle by pressure.

Die Erfindung schlägt ein Verfahren zum Entlüften einer mittels eines elastischen Stopfens verschlossenen, gefüllten Flasche vor, wobei der in die Flaschenöffnung eingesteckte Stopfen durch eine Querkraft deformiert wird, derart, dass im Dichtbereich von Stopfen und Flasche eine Luftauslassöffnung gebildet ist.The invention proposes a method for venting a filled bottle closed by means of an elastic plug, wherein the stopper inserted into the bottle opening is deformed by a transverse force such that an air outlet opening is formed in the sealing area of the stopper and bottle.

Die Erfindung macht sich die Erkenntnis zunutze, dass der beim Einstecken des Stopfens in die Flasche in Folge der hohen Füllung der Flasche sich einstellende Überdruck in der Flasche durch Deformation des Stopfens und damit Bildung einer Luftauslassöffnung zwischen Stopfen und Flasche unmittelbar abgebaut werden kann, somit ein Druckausgleich zwischen Flascheninnenraum und der Atmosphäre stattfindet. Infolgedessen wirken keine Druckkräfte im Inneren der Flasche, die zum Herausdrücken des Stopfens aus der Flasche führen. Die vorbeschriebenen Probleme bei der weiteren Verpackung der Flasche treten somit nicht auf.The invention makes use of the finding that the overpressure in the bottle which occurs when the stopper is inserted into the bottle as a consequence of the high filling of the bottle can be reduced immediately by deformation of the stopper and thus formation of an air outlet between stopper and bottle Pressure equalization between the bottle interior and the atmosphere takes place. As a result, no pressure forces in the interior of the bottle, which lead to squeezing the plug out of the bottle. The above-described problems in the further packaging of the bottle thus do not occur.

Die Deformation des Stopfens kann bereits beim Einstecken des Stopfens in die Flasche herbeigeführt werden. Grundsätzlich wäre es ausreichend, den Stopfen erst dann zu Deformieren, wenn er in die Flasche eingesteckt ist. Beim automatisierten Füllen und Verpacken ist es allerdings zweckmäßig, den Zustopfvorgang und den Entlüftungsvorgang zu überlagern. Unmittelbar nachdem der Stopfen vollständig in die Flasche eingesteckt ist, kann die weitere Verpackung der Flasche vorgenommen werden, beispielsweise in einer Bördelstation.The deformation of the plug can be brought about already during insertion of the plug into the bottle. Basically, it would be sufficient to deform the plug only when it is inserted into the bottle. In automated filling and packaging, however, it is expedient to superimpose the stuffing process and the deaeration process. Immediately after the plug is completely inserted into the bottle, the further packaging of the bottle can be made, for example in a crimping station.

Um den erfindungsgemäßen Effekt zu erzielen, reicht es grundsätzlich aus, von einer Seite seitlich gegen den aus der Flasche ragenden Ansatz zu drücken. Der Ansatz muss nicht elastisch sein. Erforderlich ist nur, dass über den Ansatz eine Querkraft in den im Flaschenkopf befindlichen Stopfen eingeleitet werden kann. Der gedrückte Stopfen weicht seitlich aus, weil sich die Deformation bis in die Flasche hinein fortsetzt und so die Luftauslassöffnung gebildet wird.In order to achieve the effect according to the invention, it is basically sufficient to press from one side laterally against the projection protruding from the bottle. The approach does not have to be elastic. It is only necessary that a lateral force can be introduced into the stopper located in the bottle head via the approach. The depressed plug deviates laterally because the deformation continues into the bottle and thus the air outlet opening is formed.

Selbstverständlich kann der Stopfen ohne Ansatz ausgeführt sein, wobei der Stopfen bei Verschluss der Flasche teilweise aus dieser ragt.Of course, the plug can be designed without an approach, wherein the plug partially protrudes from the bottle when the bottle is closed.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Quetschkräfte auf einander abgewandten Seiten des Stopfens in diesen eingeleitet werden. Durch die so erzeugte Einspannung des Stopfens lässt sich, insbesondere wenn die Flasche mit dem Stopfen bewegt wird, eine definierte Quetschcharakteristik erzeugen. Dies gilt insbesondere dann, wenn die Flasche mit auf diesem aufgesetzten Stopfen relativ zu einer Entlüftungsstation transportiert und der Stopfen quer zur Transportrichtung gequetscht wird.According to a preferred embodiment of the invention it is provided that the squeezing forces are introduced on opposite sides of the plug in this. The clamping of the plug thus produced makes it possible, in particular when the bottle is moved with the stopper, to produce a defined crushing characteristic. This applies in particular when the bottle is transported with this stopper placed on relative to a venting station and the stopper is squeezed transversely to the transport direction.

Aufgabe der Erfindung ist es ferner, eine Vorrichtung zur Durchführung des Verfahrens zu schaffen, die baulich besonders einfach gestaltet ist.The object of the invention is also to provide a device for carrying out the method, which is structurally particularly simple.

In diesem Zusammenhang wird vorgeschlagen, dass die Vorrichtung eine Quetscheinrichtung aufweist, die auf mindestens einer Seite des Stopfens angeordnet ist und in einer Richtung parallel zur durch die Flaschenöffnung gehenden Ebene wirksam ist. Diese Quetschvorrichtung ist insbesondere auf zwei einander abgewandten Seiten des Stopfens angeordnet.In this connection, it is proposed that the device has a squeezing device which is arranged on at least one side of the plug and is effective in a direction parallel to the plane passing through the bottle opening. This squeezing device is arranged in particular on two opposite sides of the plug.

Die erfindungsgemäße Vorrichtung findet insbesondere Verwendung im Zusammenhang mit einer Abfüll- und Verpackungsstation von mittels Stopfen verschlossener Flaschen, insbesondere mittels Stopfen verschlossener kleiner Fläschchen - Vials - bei denen der Vorgang des Eindrückens der Stopfen in die Flaschen vom Vorgang der Entlüftung der Flaschen überlagert ist.The device according to the invention finds particular use in connection with a filling and packaging station of bottles sealed by plugs, in particular closed by small vials stopper - vials - in which the process of indenting the stopper in the bottles is superimposed by the process of venting the bottles.

Es wird als besonders vorteilhaft angesehen, wenn die Vorrichtung einen Körper mit einem Kanal aufweist, wobei der Kanal am Anfang und am Ende offen ist, und der Kanal sich in seiner Breite verjüngt und erweitert, sowie die Breite des Kanals in dessen maximal verjüngtem Bereich geringer ist als der Durchmesser des aus der Flasche herausragenden Stopfenbereiches, wobei die seitlichen Flanken des Kanals die Quetscheinrichtung bilden. Beim Zufördern der Flasche mit dem Stopfen wird infolgedessen der oben aus der Flasche ragende Stopfenbereich in den Kanalkonus bewegt und aufgrund der Dimensionierung der sich verjüngenden Kanalbreite gequetscht. Im anschließenden sich erweiternden Kanalabschnitt, werden die Quetschkräfte reduziert und schließlich ganz aufgehoben, so dass der elastische Stopfen sich in die ursprüngliche rotationssymmetrische Gestalt ausdehnen kann. Der Körper ist insbesondere plattenförmig ausgebildet.It is considered particularly advantageous if the device comprises a body with a channel, the channel being open at the beginning and at the end, and the channel tapering and widening in width, and the width of the channel being less in its maximum tapered region is as the diameter of the protruding from the bottle stopper area, wherein the lateral edges of the channel form the squeezing. As a result, when feeding the bottle with the stopper, the stopper portion protruding from the top of the bottle is moved into the channel cone and squeezed due to the dimensioning of the tapered channel width. In the subsequent widening channel section, the squeezing forces are reduced and finally completely released, so that the elastic plug can expand into the original rotationally symmetrical shape. The body is in particular plate-shaped.

Bevorzugt weist der Körper an seiner Unterseite den Kanal auf. Der Körper wird infolgedessen oberhalb eines Transportbandes bzw. einer Transportvorrichtung für die Flaschen positioniert, und ist insbesondere stationär.The body preferably has the channel on its underside. As a result, the body is positioned above a conveyor belt for the bottles, and is particularly stationary.

Eine in den Körper integrierte Drückeinrichtung zum Eindrücken des Stopfens in die Flaschenöffnung ist insbesondere im Bereich der Quetscheinrichtung angeordnet. Baulich besonders einfach lässt sich die Drückeinrichtung verwirklichen, wenn die Tiefe des Kanals sich verjüngt, und zwar ausgehend vom Eingang des Kanals bei großer Kanalbreite bis zum Bereich des Kanals bei verjüngter Kanalbreite, wobei der Bereich minimaler Tiefe des Kanals der Endeinsteckstellung des Stopfens in der Flasche entspricht. Sobald die Flasche mit dem auf diesen aufgesteckten bzw. aufgelegten Stopfen in den Bereich des Körpers gelangt, positioniert die Dachschräge des Kanals die obere Fläche des Stopfens und es bewirkt diese Dachschräge, dass der Stopfen beim Fördern, relativ zum Körper, in die Flaschenöffnung gedrückt wird. An den Kanalbereich, in dem die minimale Kanaltiefe erreicht wird, kann sich dann ein Kanalabschnitt konstanter Kanaltiefe anschließen, der parallel zur Förderebene der Flasche angeordnet ist. Der Kanalabschnitt konstanter Kanaltiefe bewirkt damit, dass der Stopfen in der vollständig in die Flaschenöffnung eingesteckten Position gehalten wird. Um zu gewährleisten, dass zwischen dem Stopfen und dem Körper minimale Reibkräfte wirksam sind, sollte der Körper aus einem gleitfähigem Kunststoff bestehen.An integrated into the body pressing means for pushing the plug into the bottle opening is arranged in particular in the region of the squeezing device. Structurally particularly simple, the pusher can be realized when the depth of the channel tapers, from the entrance of the channel with large channel width to the region of the channel with tapered channel width, wherein the region of minimum depth of the channel of Endinsteckstellung the plug in the bottle equivalent. As soon as the bottle reaches the area of the body with the plug placed on it, the roof slope of the channel positions the top surface of the plug and this sloping roof causes the plug to be pressed into the bottle opening when it is being conveyed relative to the body , At the channel region, in which the minimum channel depth is reached, then a channel section of constant channel depth can connect, which is arranged parallel to the conveying plane of the bottle. The channel portion of constant channel depth thus causes the plug to be held in the fully inserted into the bottle opening position. To ensure minimal frictional forces between the plug and the body, the body should be made of a lubricious plastic.

Gemäß einer vorteilhaften Gestaltung ist vorgesehen, dass der Körper in Längsrichtung des Kanals vertikal geschlitzt ist, wobei der Schlitz in Abstand von dem Kanalanfang endet. Sollte eine Flasche mit Stopfen bei einer Störung nicht richtig in den Kanal eingeführt werden können, kann infolge der Schlitzanordnung derjenige Bereich des Körpers, der auf den Stopfen einwirkt, zurückfedern. Ein Bruch der üblicherweise aus Glas bestehenden Flaschen ist hierdurch ausgeschlossen.According to an advantageous embodiment, it is provided that the body is slotted vertically in the longitudinal direction of the channel, wherein the slot ends at a distance from the channel beginning. Should a stoppered bottle fail to be properly inserted into the channel in the event of a malfunction, the portion of the body which acts on the stopper may spring back due to the slot arrangement. A break of the usually made of glass bottles is thereby excluded.

Der Körper 12 ist oberhalb der mit den Gummistopfen 10 versehenen Fläschchen 2 angeordnet und auf seiner Oberseite 13 eben ausgebildet. Diese verläuft horizontal. Der Körper 12 ist mit einer oberen Halteplatte 14 mittels Schrauben 15 befestigt. Die Halteplatte 14 ist in einem vertikal angeordneten, stationären stangenförmigen Ständer 16 vertikal verschiebbar gelagert und mittels eines eine Klemmschraube aufweisenden Klemmelementes 17 in beliebiger Höhe fixierbar.A arranged above the turntable 7 means 8 with a plurality of perpendicular to the bottom plate 4 vertically movable plungers 9 is used for loose placement of rubber stopper 10 on the located in the plunger 9 vial 2. The device 8 is arranged downstream of the ventilation device 11 according to the invention, a profiled body 12, which consists of lubricious plastic. The body 12 is disposed above the bottles 2 provided with the rubber stoppers 10 and formed flat on its upper surface 13. This runs horizontally. The body 12 is secured to an upper support plate 14 by means of screws 15. The holding plate 14 is mounted vertically displaceable in a vertically arranged, stationary rod-shaped stand 16 and fixed by means of a clamping screw having a clamping element 17 at any height.

Der konkrete Aufbau der Entlüftungsvorrichtung 11 und deren Wirkungsweise ist in den Figuren 2 bis 8 veranschaulicht:The concrete construction of the ventilation device 11 and its mode of action is illustrated in FIGS. 2 to 8:

Der Körper 12 weist auf seiner Unterseite einen Kanal 18 auf. Dieser ist an seinem Anfang, dargestellt durch die Stirnfläche 19, und an seinem Ende, dargestellt durch die Stirnfläche 20 des Körpers, 12 offen. Ausgehend von seinem Anfang verjüngt sich der Kanal 18 in seiner Breite, wobei die maximale Verjüngung etwa auf halber Länge des Kanals 18 erreicht ist. Von dort erweitert sich der Kanal 18 zu seinem Ende. Die Breite des Kanals 18 ist in dessen maximal verjüngtem Bereich geringer als der Durchmesser des aus dem Fläschchen 2 herausragenden Abschnittes 22 des Stopfens 10. Wird der Abschnitt 22 des Stopfens 10 durch diesen Bereich 21 des Kanals 18 bewegt, ergibt sich die in den Figuren 3 und 4 veranschaulichte Deformation des Abschnittes 22. Der Kanal 18 ist durch eine, bezogen auf den Förderweg der Fläschchen 2, radial äußere gerade Flanke 23 und eine gekrümmte innere Flanke 24 gebildet. Die beiden Flanken 23 und 24 begrenzen äußere, gegenüber dem Kanalboden 25 erhabene Abschnitte 26 und 27 des Körpers 12. Die Flanken 23 und 24 bilden eine Quetscheinrichtung für die entlang des Kanales 18 bewegten Abschnitte 22 der Stopfen 10.The body 12 has a channel 18 on its underside. This is at its beginning, represented by the end face 19, and at its end, represented by the end face 20 of the body, 12 open. Starting from its beginning, the channel 18 tapers in its width, wherein the maximum taper is reached at about half the length of the channel 18. From there, the channel 18 extends to its end. The width of the channel 18 is in its maximum tapered region less than the diameter of the projecting out of the vial 2 section 22 of the plug 10. If the portion 22 of the plug 10 moves through this region 21 of the channel 18, the results in the figures 3 and FIG. 4 illustrates deformation of section 22. Channel 18 is defined by a reference to FIG Delivery path of the vial 2, radially outer straight edge 23 and a curved inner edge 24 is formed. The two flanks 23 and 24 delimit outer, opposite the channel bottom 25 raised portions 26 and 27 of the body 12. The flanks 23 and 24 form a squeezing device for the along the channel 18 moving portions 22 of the plug 10th

Der Körper 12 ist im Bereich seines Kanalbodens 25, ausgehend von der Stirnfläche 20, mit einem den Körper 12 durchsetzenden Schlitz 28 versehen. Dieser verläuft parallel zur äußeren Flanke 23. Der Schlitz 28 endet mit einem Abstand von der anderen Stirnfläche 19, der in etwa der Kanalbreite im Bereich des maximal verjüngten Bereiches 21 entspricht.The body 12 is provided in the region of its channel bottom 25, starting from the end face 20, with a slot 28 penetrating the body 12. This extends parallel to the outer edge 23. The slot 28 terminates at a distance from the other end face 19, which corresponds approximately to the channel width in the region of the maximum tapered region 21.

Insbesondere der Darstellung der Figuren 5 und 8 ist zu entnehmen, dass der Kanalboden 25 über seine Länge nicht eben und nicht horizontal ist, sondern einen oder mehrere schräge Einführabschnitte 30 aufweist, derart, dass sich die Plattenstärke des Körpers 12, ausgehend von der dem Einführbereich der Fläschchen zugeordneten Stirnfläche 20 des Körpers 12 , vergrößert. Die Wandstärke des Körpers 12 im Bereich des Kanalbodens 25 nimmt bis zur Stelle 29 zu, die, bezogen auf die Förderrichtung der Fläschchen 2, hinter dem maximal verjüngten Bereich 21 des Kanals 18 liegt. Ab dieser Stelle 29 verläuft der Kanalboden 25 horizontal. Diese Ausbildung des Kanalbodens 25 führt dazu, dass diesem die Funktion einer Drückeinrichtung zukommt, die bewirkt, dass der Abschnitt 22 des Stopfens 10 gegen einen oberen Wulstansatz 31 des jeweiligen Fläschchens 2 gedrückt wird und der mit dem Abschnitt 22 verbundene Stopfenabschnitt 32 maximal in die Flaschenöffnung 35 eingeführt ist.In particular, the representation of Figures 5 and 8 it can be seen that the channel bottom 25 is not flat and not horizontal over its length, but one or more oblique insertion sections 30, such that the plate thickness of the body 12, starting from the insertion the vial associated end face 20 of the body 12, increased. The wall thickness of the body 12 in the region of the channel bottom 25 increases up to the point 29, which, based on the conveying direction of the vial 2, behind the maximum tapered portion 21 of the channel 18. From this point 29, the channel bottom 25 extends horizontally. This formation of the channel bottom 25 causes it to perform the function of a pressing device, which causes the portion 22 of the plug 10 is pressed against an upper Wulstansatz 31 of the respective vial 2 and the portion 22 connected to the plug portion 32 maximum in the bottle opening 35 is introduced.

Der Funktionsablauf des Eindrückens des Gummistopfens 10 in das jeweilige Fläschchen 2 ist in der Figur 5 veranschaulicht. Die Figur 4 zeigt den überlagerten Funktionsablauf des Quetschens der Abschnitte 22 der Gummistopfen 10. Der jeweilige Abschnitt 22 wird deformiert, wobei sich die Deformation des Abschnittes 22 in den Stopfenabschnitt 32 fortsetzt, so dass beim Einstecken des Stopfens 10 in das jeweilige Fläschchen 2 zwischen dem Stopfenabschnitt 32 und dem Fläschchen 2 eine Luftauslassöffnung gebildet ist. Diese ist in Figur 4 indirekt veranschaulicht. So ist die Förderbahn der Abschnitte 22 der Stopfen 10 mit strichlierten Linien 33 und 34 veranschaulicht. Diese Figur veranschaulicht, dass im maximal verjüngten Bereich 21 des Kanals 18 der ellipsenförmig deformierte Abschnitt 22 in Abstand zur Linie 33 positioniert ist. Dieses Abstandsmaß ist ein Referenzmaß für die Verformung des Stopfenabschnittes 22 auf dieser Seite des Stopfens 10 mit der Folge der dort zwischen dem Stopfenabschnitt 22 und dem Fläschchen 2 gebildeten Luftauslassöffnung.The functional sequence of the depression of the rubber stopper 10 into the respective vial 2 is illustrated in FIG. FIG. 4 shows the superimposed functional sequence of squeezing the sections 22 of the rubber stoppers 10. The respective section 22 is deformed, with the deformation of the section 22 continuing in the stopper section 32, so that when the stopper 10 is inserted into the respective vial 2 between the stoppers Plug portion 32 and the vial 2, an air outlet opening is formed. This is illustrated indirectly in FIG. Thus, the conveying path of the sections 22 of the plugs 10 is illustrated by dashed lines 33 and 34. This figure illustrates that in the maximum tapered portion 21 of the channel 18, the elliptically deformed portion 22 is positioned at a distance from the line 33. This distance measure is a reference measure for the deformation of the plug portion 22 on this side of the plug 10 with the consequence of the air outlet opening formed there between the plug portion 22 and the vial 2.

Die Fläschchen 2 mit den Stopfen 10 werden kontinuierlich entlang der Entlüftungsvorrichtungen 11 transportiert. Sollte ein Fläschchen bei der fehlerhaften Förderung gegen den Abschnitt stoßen, kann dieser wegen des Schlitzes 28 im Körper 12 zurückfedern, ohne dass Glasbruch entsteht.The vials 2 with the plugs 10 are transported continuously along the venting devices 11. If a vial in the faulty promotion abut the section, this can spring back because of the slot 28 in the body 12, without breaking glass.
