Description

Gebiet der TechnikField of engineering

Die Erfindung betrifft eine Verschlussvorrichtung für einen Behälter, insbesondere einen Glasbehälter, mit einer Behälteröffnung, wobei die Verschlussvorrichtung ein Deckelelement zum Verschließen der Behälteröffnung, eine an dem Deckelelement angeordnete Kammer und ein Innengehäuse aufweist, wobei Kammer und Innengehäuse zueinander korrespondierende Verschlussmittel und Öffnungsmittel aufweisen, welche so in Wechselwirkung zueinander stehen, dass eine der Kammer zugeordnete Ablassöffnung durch eine Bewegung des Deckelelementes relativ zu dem Innengehäuse freigebbar ist, so dass ein in der Kammer bevorratetes Medium in den Behälter austreten kann, und die Kammer und das Innengehäuse jeweils korrespondierende und bezüglich einer Gewindedrehachse ausgebildete erste Gewindemittel aufweisen.The invention relates to a closure device for a container, in particular a glass container, having a container opening, wherein the closure device comprises a lid member for closing the container opening, a chamber arranged on the lid member and an inner housing, said chamber and inner housing having mutually corresponding closure means and opening means, which interact with one another such that a discharge opening associated with the chamber is releasable relative to the inner housing by movement of the cover element so that a medium stored in the chamber can exit into the container, and the chamber and the inner housing respectively corresponding and with respect to a thread rotation axis having trained first thread means.

Stand der TechnikState of the art

Verschlussvorrichtungen der vorgenannten Art sind im Stand der Technik bekannt. Diese dienen dazu, einen Behälter, beispielsweise eine Getränkeflasche, zu verschließen, und gleichzeitig eine Kammer zur separaten Speicherung von flüssigen oder pulverförmigen Zutaten, beispielsweise Tee-Essenzen, bereitzustellen, so dass diese nicht unmittelbar beim Befüllen mit dem Inhalt des Behälters, d.h. beispielsweise Wasser, in Berührung kommen und/oder gemischt werden, sondern erst in dem Moment, in dem die Verschlussvorrichtung von dem Behälter entfernt wird. Dies ist regelmäßig der Moment, in welchem ein Benutzer das in dem Behälter befindliche Getränk konsumieren möchte.Closure devices of the aforementioned type are known in the art. These serve to seal a container, for example a beverage bottle, and at the same time provide a chamber for the separate storage of liquid or powdered ingredients, such as tea essences, so that they do not immediately upon filling with the contents of the container, i. For example, water, come into contact and / or mixed, but only at the moment in which the closure device is removed from the container. This is usually the moment when a user wants to consume the beverage in the container.

Die im Stand der Technik bekannten Verschlussvorrichtungen bestehen regelmäßig aus einem Deckelelement, an welchem die Kammer angeordnet ist, und einem Innengehäuse. Die Verschlussvorrichtung wird in der Regel als Ganzes, d.h. vollständig vormontiert, auf den Behälter aufgeschraubt. Zu diesem Zweck weist das Innengehäuse ein mit dem Gewinde des Behälters formschlüssig korrespondierendes Gewinde auf. Darüber hinaus sind Deckelelement und Innengehäuse über formschlüssig korrespondierende Gewinde miteinander verbunden. Bei einem Öffnen des Behälters, d.h. bei einem Abschrauben des Deckelelementes, wird das Deckelelement - und damit auch die an dem Deckelelement angeordnete Kammer - relativ zu dem Innengehäuse bewegt. Dabei wird das Deckelelement von einer Schließposition in eine Ablassposition bewegt, in welcher Ablassposition ein in der Kammer bevorratetes Medium in den Behälter austreten kann. Dazu weisen Kammer und Innengehäuse zueinander korrespondierende Verschlussmittel und Öffnungsmittel zum Verschließen bzw. Öffnen der Ablassöffnung auf. Diese korrespondierenden Verschluss- und Öffnungsmittel können beispielsweise in Form eines einzigen an dem Innengehäuse angeordneten Stopfenelementes ausgebildet sein, wobei ein erster Endbereich das Verschlussmittel und ein zweiter Endbereich das Öffnungsmittel bildet. Das Stopfenelement verhindert oder erlaubt je nach seiner Stellung innerhalb der Auslassöffnung der Kammer ein Austreten des Mediums in den Behälter. Alternativ können die korrespondierenden Verschluss- und Öffnungsmittel jedoch auch getrennte Elemente sein, wie beispielsweise eine die Auslassöffnung der Kammer verschließende Membran und ein an dem Innengehäuse angeordneter Dorn. Bei einer Bewegung des Deckelelementes relativ zu dem Innengehäuse kommt es zu einer Zerstörung des Verschlussmittels durch das Öffnungsmittel, wobei die Ablassöffnung der Kammer freigegeben wird und das Medium in den Behälter austreten kann.The closure devices known in the prior art regularly consist of a cover element, on which the chamber is arranged, and an inner housing. The closure device is usually called Whole, ie completely pre-assembled, screwed onto the container. For this purpose, the inner housing has a form-fitting corresponding to the thread of the container thread. In addition, the cover element and the inner housing are connected to each other via form-fitting corresponding threads. When the container is opened, ie when the cover element is unscrewed, the cover element-and thus also the chamber arranged on the cover element-is moved relative to the inner housing. In this case, the cover element is moved from a closed position to a discharge position, in which discharge position a medium stored in the chamber can escape into the container. For this purpose, the chamber and inner housing have mutually corresponding closure means and opening means for closing or opening the discharge opening. These corresponding closure and opening means may, for example, be in the form of a single stopper element arranged on the inner housing, wherein a first end region forms the closure means and a second end region forms the opening means. The plug element prevents or permits leakage of the medium into the container, depending on its position within the outlet opening of the chamber. Alternatively, however, the corresponding closure and opening means may also be separate elements, such as a membrane occluding the outlet opening of the chamber and a mandrel disposed on the inner housing. Upon movement of the cover element relative to the inner housing, the closure means is destroyed by the opening means, whereby the discharge opening of the chamber is released and the medium can escape into the container.

Die Druckschrift WO 2007/129116 A1 betrifft beispielsweise eine Verschlussvorrichtung nach dem Stand der Technik zum Anbringen an einen Behälter. Die Verschlussvorrichtung weist ein Deckelelement auf, welches eine Kammer definiert, sowie ein Innengehäuse mit einem Stopfenelement, das abdichtend in eine Ablassöffnung in einer unteren Wand der Kammer eingreifbar ist. Das Deckelelement ist mit einem Gewinde versehen, das in ein entsprechendes Gewinde des Innengehäuses eingreifen kann, um zu ermöglichen, dass das Deckelelement relativ zu dem Innengehäuse aus einer Schließposition, in der das Stopfenelement die Ablassöffnung der Kammer verschließt, in eine Ablassposition, in der das Stopfenelement mindestens teilweise aus der Ablassöffnung zurückgezogen ist, verschoben wird, um einen zwischen Kammer und Behälter angeordneten Ablasskanal freizugeben.The publication WO 2007/129116 A1 For example, there is a prior art closure device for attachment to a container. The closure device comprises a lid member defining a chamber and an inner housing having a plug member sealingly engageable with a discharge opening in a lower wall of the chamber. The cover member is threaded to engage a corresponding thread of the inner housing to allow the cover member to move relative to the inner housing from a closed position the plug member closes the discharge opening of the chamber, is displaced to a discharge position in which the plug member is at least partially retracted from the discharge opening to release a discharge channel disposed between the chamber and the container.

Zum Stand der Technik ist weiter auf die EP 520207 A1 , die gattungsbildende CN 102785846 A , die US 2008/314775 A1 und die US 2014/110281 A1 zu verweisen. Die Verschlussmittel in einer Dichtungsebene sind bei diesen bekannten Verschlussvorrichtungen jeweils einheitlich aus einem Werkstoff gebildet.The state of the art is further on the EP 520207 A1 , the generic CN 102785846 A , the US 2008/314775 A1 and the US 2014/110281 A1 to refer. The closure means in a sealing plane are each uniformly formed from a material in these known closure devices.

Zusammenfassung der ErfindungSummary of the invention

Ausgehend von einem Stand der Technik gemäß der vorerwähnten CN 102785846 A beschäftigt sich die Erfindung mit der Aufgabenstellung, eine Verschlussvorrichtung der genannten Art anzugeben, welche hinsichtlich einer Verbindung der Kammer mit dem Deckelelement vorteilhaft gestaltet ist.Starting from a prior art according to the aforementioned CN 102785846 A The invention is concerned with the task of specifying a closure device of the type mentioned, which is advantageously designed with respect to a connection of the chamber with the lid member.

Diese Aufgabe ist beim Gegenstand des Anspruches 1 gelöst, wobei darauf abgestellt ist, dass die Kammer an das Deckelelement angeschweißt ist, wobei die Kammer eine Öffnung mit einem kragenförmig abgekanteten Randbereich als einen Verbindungsflansch aufweist, welcher im Wesentlichen parallel zu einer benachbarten Oberfläche des Deckelelementes ausgerichtet ist, und dass die Kammer entlang des hierdurch ringförmig gebildeten Bereiches mit dem Deckelelement verbunden ist. Das Deckelelement verschließt gleichzeitig die in der Kammer ausgebildete Öffnung. Somit kann das Deckelelement sowohl als Verschlusselement für die Öffnung der Kammer als auch als Verschlusselement für den Behälter an sich dienen. Das Verschweißen kann dabei auf unterschiedliche Art und Weise erfolgen, beispielsweise mittels Ultraschall, Induktion oder auch Widerstandsheizung.This object is achieved in the subject matter of claim 1, wherein it is pointed out that the chamber is welded to the cover element, wherein the chamber has an opening with a collar-shaped folded edge portion as a connecting flange, which is aligned substantially parallel to an adjacent surface of the cover element is, and that the chamber is connected along the annularly formed thereby region with the lid member. The lid member simultaneously closes the opening formed in the chamber. Thus, the lid member can serve both as a closure element for the opening of the chamber and as a closure element for the container itself. The welding can be done in different ways, for example by means of ultrasound, induction or resistance heating.

Der kragenförmig abgekantete Randbereich kann dabei insbesondere ein um 90° abgekanteter Bereich der Wandung der Kammer sein. Dadurch entsteht auf besonders einfache Art und Weise ein Bereich, der parallel zu der Oberfläche des Deckelelementes ausgerichtet ist. Bei dem Schweißvorgang wird dieser Bereich vorteilhaft genutzt, um das Deckelelement mit der Kammer zu verschweißen. Um die Haftung zwischen dem Aluminium-Deckelelement und der Kammer zu erhöhen, empfiehlt es sich zudem, dass das Deckelelement im Bereich der Schweißstelle mit einem Lack beschichtet ist. Der Lack ist in seiner Zusammensetzung auf das jeweilige Material der Kammer abzustimmen.The collar-shaped folded edge region may in particular be an area of the wall of the chamber which is bent by 90 °. This results in a particularly simple manner, an area which is aligned parallel to the surface of the cover element. In the welding process, this area is advantageously used to weld the lid member to the chamber. In order to increase the adhesion between the aluminum cover element and the chamber, it is also recommended that the cover element is coated in the region of the weld with a lacquer. The paint is to be matched in its composition to the respective material of the chamber.

Es kann weiterhin vorgesehen sein, dass der abgekantete Randbereich der Kammer in radialer Richtung des Verschlusselementes über einen dazu benachbart angeordneten Randbereich des Innengehäuses hinausragt. Damit wird an dem Deckelelement ein "Vorsprung" oder eine hervorstehende "Nase" geschaffen, um welche das Aluminium des Deckelelementes gerollt ist, so dass die Verbindung zwischen Kammer und Deckelelement zusätzlich verstärkt wird. Es ist somit sichergestellt, dass bei einem Abdrehen des Deckelelementes von dem Behälter gleichzeitig auch die Kammer mitbewegt wird.It can further be provided that the bent edge region of the chamber protrudes in the radial direction of the closure element via an edge region of the inner housing arranged adjacent thereto. Thus, a "projection" or a protruding "nose" is created on the lid member, around which the aluminum of the lid member is rolled, so that the connection between the chamber and lid member is additionally reinforced. It is thus ensured that at a twisting of the lid member of the container at the same time the chamber is moved.

Es kann vorgesehen sein, dass die Verschlussmittel in einer Dichtungsebene radial außen einen Weichkunststoff aufweisen und radial innen einen Hartkunststoff. Eine solche Ausgestaltung bietet die Herstellung der Verschlussmittel in einem 2-Komponenten-Herstellungsverfahren an.It can be provided that the closure means in a sealing plane radially outwardly comprise a soft plastic and radially inside a hard plastic. Such an embodiment offers the production of the closure means in a 2-component manufacturing process.

Der äußere Weichkunststoff kann, wie bevorzugt, Dichtungseigenschaften übernehmen, womit der gegebenenfalls gesonderte Einsatz einer Dichtung in der Dichtungsebene entfallen kann.The outer soft plastic can, as preferred, take over sealing properties, whereby the optionally separate use of a seal in the sealing plane can be omitted.

Die Verschlussmittel können vollständig oder auch nur teilweise radial außen einen Weichkunststoff aufweisen, gegebenenfalls entsprechend teilweise unterbrochen von Hartkunststoffbereichen.The closure means may comprise completely or even partially radially outwardly a soft plastic, optionally correspondingly partially interrupted by hard plastic regions.

Es kann vorgesehen sein, dass die Kammer einen zweiten Bereich oberhalb der und/oder in horizontaler Überdeckung zu den ersten Gewindemitteln und/oder unterhalb der ersten Gewindemittel aufweist, wobei bezogen auf die Gewindedrehachse der erste Bereich radial größer ausgestaltet ist als der Bereich, in dem sich die Kammer oberhalb der ersten Gewindemittel seitlich bis über die ersten Gewindemittel hinaus erstreckt (erster Bereich).It can be provided that the chamber has a second region above and / or in horizontal overlap to the first thread means and / or below the first thread means, wherein with respect to the thread rotation axis, the first region is made radially larger than the region in which the chamber extends laterally beyond the first thread means above the first thread means (first area).

Der zweite Bereich kann hinsichtlich seiner Radialerstreckung begrenzt sein durch einschränkende Abmaße des Behälters, insbesondere der Behälteröffnung. So kann sich der zweite Bereich in Zuordnungs- und Nutzungsstellung innerhalb eines Behälterhalses erstrecken. Der sich an diesen zweiten Bereich nach vertikal oben erstreckende erste Bereich kann dem Behälter so zugeordnet sein, dass eine hierdurch bedingte Einschränkung bezüglich des radialen Erstreckungsmaßes des ersten Bereiches nicht gegeben ist, so dass dieser gegenüber dem zweiten Bereich quer zu einer Gewindedrehachse betrachtet größer gewählt sein kann.The second region can be limited in terms of its radial extent by restricting dimensions of the container, in particular the container opening. Thus, the second area may extend in assignment and use position within a container neck. The first region extending vertically upwards at this second region may be associated with the container in such a way that there is no restriction with respect to the radial extension dimension of the first region, so that it is chosen to be larger than the second region transverse to a thread rotation axis can.

Hierdurch ist insgesamt eine Vergrößerung des Aufnahmevolumens der Kammer bei gleichem Behälter erreichbar.As a result, an overall increase in the receiving volume of the chamber can be achieved with the same container.

Der erste Bereich kann hierbei ein Radialmaß aufweisen welches dem eines zugeordneten Behälterabschnittes, beispielsweise eines die Behälteröffnung aufweisenden Behälterhalses, entspricht. Weiter kann das Radialmaß des ersten Bereiches der Kammer einem 1,2-Fachen oder mehr bis hin zu einem 5-Fachen, bevorzugt etwa einem 2-Fachen des entsprechenden Radialmaßes des zweiten Bereiches entsprechen.The first region may in this case have a radial dimension which corresponds to that of an associated container section, for example a container neck having the container opening. Further, the radial dimension of the first region of the chamber may correspond to 1.2 times or more up to a 5 times, preferably about 2 times, the corresponding radial dimension of the second region.

Weiter kann vorgesehen sein, dass die Kammer - bezogen auf eine Nutzungsstellung - oberseitig der ersten Gewindemittel eine horizontale Teilung aufweist.Furthermore, it can be provided that the chamber has a horizontal division on the upper side of the first thread means, with reference to a utilization position.

Es kann so eine Mehrteiligkeit der Kammer erreicht sein. Dies bietet herstellungstechnische Vorteile. Darüber hinaus kann durch eine horizontale Teilung oberseitig der ersten Gewindemittel ein Kammer-Oberteil als Kammerdeckel ausgebildet sein, zur bevorzugt dichtenden Zuordnung zu dem Kammerunterteil nach einem Befüllen der Kammer mit der zu bevorratenden Flüssigkeit. Die Verbindung zwischen Kammeroberteil und Kammerunterteil kann durch eine Gewindeverschraubung realisiert sein oder auch durch eine Klipsbeziehungsweise Prellverbindung. Darüber hinaus ist auch eine Verschweißung oder (lebensmittelechte) Verklebung möglich.It can be achieved as a multi-part of the chamber. This offers manufacturing advantages. In addition, by a horizontal division top side of the first thread means a chamber upper part may be formed as a chamber lid, for preferably sealing assignment to the chamber bottom after filling the chamber with the liquid to be stored. The connection between the upper chamber part and lower chamber part can be realized by a threaded connection or by a Klipsbeziehungsweise bouncing. In addition, a welding or (food-safe) bonding is possible.

Die horizontale Teilung bezieht sich bevorzugt auf eine Nutzungsstellung der Verschlussvorrichtung beziehungsweise des Behälters, bei welcher sich eine Vorrichtungs-Längsachse beziehungsweise eine Behälterlängsachse in einer Vertikalen erstreckt. Auch kann sich die Teilungsebene quer gerichtet zu einer Behälterhalsachse erstrecken.The horizontal division preferably relates to a utilization position of the closure device or of the container, in which a device longitudinal axis or a container longitudinal axis extends in a vertical direction. Also, the dividing plane may extend transversely directed to a container neck axis.

Die Kammer kann aus mehreren Teilen zusammengesetzt sein und sich bezogen auf eine Nutzungsstellung des Behälters oberseitig über die ersten Gewindemittel hinaus vertikal fortsetzen, wobei ein erster Teil ausgehend von einem Verbindungsbereich mit dem zweiten Teil eine Erstreckung nach vertikal oben aufweist und zumindest teilweise oberhalb der ersten Gewindemittel angeordnet ist.The chamber may be composed of several parts and, based on a use position of the container, continue vertically above the first thread means, a first part having an extension vertically upwards from a connection region with the second part and at least partially above the first thread means is arranged.

Weiter kann vorgesehen sein, dass sich die Kammer oberhalb der ersten Gewindemittel seitlich bis über die ersten Gewindemittel hinaus erstreckt.It can further be provided that the chamber extends laterally beyond the first thread means above the first thread means.

Hierdurch ist eine radiale Kammererweiterung oberhalb der ersten Gewindemittel erreichbar, was insgesamt zu einer günstigen Volumenvergrößerung der Kammer bei gleicher Behälteröffnung beziehungsweise gleichem Behälterhals-Durchmesser führt. Die seitliche beziehungsweise mit Bezug auf eine Vorrichtungsachse radiale Erweiterung der Kammer oberhalb der ersten Gewindemittel kann sich maßlich orientieren an einem, mit dem Behälterhals bevorzugt über ein Gewinde zusammenwirkenden Deckelelement. Weiter kann die radiale Erweiterung der Kammer oberhalb der ersten Gewindemittel orientiert sein an den Außendurchmesser des Behälters im Bereich der Behälteröffnung. Durch Veränderung der quer und/oder längs zu der Vorrichtungsachse betrachteten Abmaße der Kammererweiterung ist eine Anpassung der Verschlussvorrichtung an unterschiedliche Mengen zu bevorratender Substanzen in der Vorrichtung ermöglicht.As a result, a radial chamber extension above the first thread means can be achieved, which leads to an overall increase in volume the chamber at the same container opening or the same container neck diameter leads. The lateral or with respect to a device axis radial extension of the chamber above the first thread means may be dimensionally oriented on a, preferably cooperating with the container neck via a threaded cover element. Further, the radial extension of the chamber above the first thread means may be oriented to the outer diameter of the container in the region of the container opening. By varying the dimensions of the chamber extension considered transversely and / or longitudinally relative to the device axis, it is possible to adapt the closure device to different amounts of substances to be stored in the device.

Es kann in einer nicht erfindungsgemäßen Variante weiter vorgesehen sein, dass die Kammer zusätzlich mit dem Deckelelement formschlussverbunden ist. Durch die Formschlussverbindung kann über das Deckelelement bei einer Drehung derselben die Kammer mitverlagert werden. So kann weiter die Kammer mit dem Deckelelement linear entlang einer Vorrichtungs-Längsachse beziehungsweise einer Behälteröffnungs-Längsachse bei Drehbetätigung des Deckelelements bewegt werden und/oder zufolge drehfester Verbindung um die Längsachse drehbewegt werden.It may be further provided in a variant not according to the invention that the chamber is in addition positively connected to the cover element. Through the form-fitting connection can be mitverlagert on the lid member during a rotation of the same chamber. Thus, furthermore, the chamber with the cover element can be moved linearly along a longitudinal axis of the device or a longitudinal axis of the container opening during rotational actuation of the cover element and / or can be rotated about the longitudinal axis as a result of a rotationally fixed connection.

Zur Formschlussverbindung kann die Kammer mit Bezug auf eine Vorrichtungs-Längsachse radial vorstehende Vorsprünge oder Rippen aufweisen, welche mit entsprechend positionierten Gegen-Formschlussmitteln des Deckelelementes zusammenwirken. Solche Gegen-Formschlussmittel am Deckelelement können im Zuge der Herstellung des Deckelelementes angeformt beziehungsweise ausgeformt sein oder auch im Zuge der Anordnung des Deckelelementes an der der Behälteröffnung zugeordneten Verschlussvorrichtung ausgeformt werden, beispielsweise durch Anrollen bei Ausbildung des Deckelelements aus Aluminium.For positive connection, the chamber may have radially projecting projections or ribs with respect to a longitudinal axis of the device, which cooperate with correspondingly positioned counter-positive engagement means of the cover element. Such counter-form-fitting means on the lid member may be formed or formed in the course of the production of the lid member or in the course of the arrangement of the lid member to the container opening associated closure device, for example by rolling in training of the lid member made of aluminum.

Zudem kann vorgesehen sein, dass eine einem Kammerinneren zugewandte Stirnfläche der Verschlussmittel ganz oder teilweise aus einem Weichkunststoff gebildet ist.In addition, it may be provided that an end face of the closure means facing a chamber interior is wholly or partially formed from a soft plastic.

Hierdurch ist eine günstige Möglichkeit gegeben, die Verschlussmittel in einem Mehrfachwerkzeug herzustellen. Auch kann hierdurch ein auf die in der Kammer zu bevorratende Flüssigkeit abgestimmter Werkstoff genutzt werden, dies gegebenenfalls unter Berücksichtigung einer ausreichenden (Kern-) Stabilität, welche durch den radial inneren (härteren) Werkstoff gegeben sein kann.This gives a favorable possibility to produce the closure means in a multiple tool. This also makes it possible to use a material which is matched to the liquid to be stored in the chamber, if appropriate taking into account a sufficient (core) stability, which can be provided by the radially inner (harder) material.

Der zweite Bereich kann einen zur Anpassung an den ersten Bereich erforderlichen Erweiterungsbereich aufweisen, der bevorzugt integral materialeinheitlich angeformt ist. In einer bevorzugten Ausgestaltung erstreckt sich der Erweiterungsbereich in üblicher Nutzungsstellung des Behälters vertikal oberhalb der Behälteröffnung. Der Erweiterungsbereich kann mit Bezug auf einen Vertikalschnitt stufenartig ausgebildet sein.The second region may have an extension region required for adaptation to the first region, which is preferably integrally formed integrally with material. In a preferred embodiment, the extension region extends in the usual use position of the container vertically above the container opening. The extension region may be formed stepwise with respect to a vertical section.

Auch kann der Erweiterungsbereich mit Bezug auf einen Vertikalschnitt einen Konusbereich aufweisen, insbesondere einen in Nutzungsstellung nach radial innen abfallenden Konusbereich. Hierdurch ist eine verbesserte Restentleerung der Kammer, insbesondere des ersten Bereichs der Kammer erreicht.The enlargement region can also have a cone region with respect to a vertical section, in particular a cone region which slopes radially inward in the use position. As a result, an improved emptying of the chamber, in particular the first region of the chamber is achieved.

Die beiden Kammerteile können, wie auch bevorzugt, aus zueinander verschweißbaren Kunststoffen bestehen. Bevorzugt bestehen die beiden Kammerteile aus identischen thermoplastischen Kunststoffen.The two chamber parts can, as also preferred, consist of plastics which can be welded together. Preferably, the two chamber parts consist of identical thermoplastic materials.

In einer bevorzugten Ausgestaltung kann der Erweiterungsbereich der Kammer eine radiale Erstreckung aufweisen, die dem 0,8- bis 1,2-Fachen des Durchmessers am Gewindegrund eines zweiten Gewindes, zur Zusammenwirkung mit dem Behälter, entspricht. Hierdurch ist eine günstige Handhabung der Verschlussvorrichtung gegeben. Das mit dem zweiten Gewinde des Behälters zusammenwirkende Deckelelement ist im Bereich der Kammererweiterungen nicht oder nicht wesentlich in dessen Durchmesser gegenüber dem Gewindebereich vergrößert. Darüber hinaus ist zufolge der Ausbildung des Erweiterungsbereiches die Angriffsfläche der sich im Wesentlichen konzentrisch zur Gewindedrehachse erstreckenden Deckelelementwandung durch den sich über die Behälteröffnung vertikal hinaus erstreckenden Kammerbereich vergrößert, was einen verminderten Kraftaufwand beim Öffnen der Verschlussvorrichtung zur Folge haben kann.In a preferred embodiment, the widening region of the chamber may have a radial extension which corresponds to 0.8 to 1.2 times the diameter at the root of a second thread for cooperation with the container. This is a cheap handling given the closure device. The cooperating with the second thread of the container lid member is not or not significantly increased in diameter in the region of the chamber extensions relative to the threaded portion. In addition, according to the formation of the extension region, the engagement surface of the substantially concentric with the thread rotation axis extending Deckelelementwandung by extending beyond the container opening vertically extending chamber area, which may result in a reduced effort when opening the closure device result.

Die Kammer kann von einer äußeren metallischen Hülse umfasst sein. Diese ist weiter bevorzugt drehfest mit den Kammerteilen verbunden. Es kann sich hierbei um eine Aluminiumhülse handeln. Bevorzugt ist der radiale Erweiterungsbereich der Kammer auch nach Abnehmen der Kammer von dem Behälter an der Hülse gefasst. Hierzu kann in üblicher Nutzungsstellung vertikal unterhalb des Erweiterungsbereiches ein radial eingezogener Abschnitt der Hülse dienen. Dieser kann bei einem üblichen Anrollen der Hülsenwandung an das behälterseitige zweite Gewinde ausgeformt werden.The chamber may be surrounded by an outer metallic sleeve. This is further preferably rotatably connected to the chamber parts. It may be an aluminum sleeve. Preferably, the radial extension portion of the chamber is taken even after removing the chamber from the container to the sleeve. For this purpose, a radially retracted portion of the sleeve can serve in the usual use position vertically below the extension region. This can be formed in a conventional rolling the sleeve wall to the container-side second thread.

Das insgesamt eingeschlossene Volumen der Kammer kann sich zu 40% oder mehr, bspw. zu 60% oder auch 80% bis hin zu 95% des Gesamtvolumens oberhalb einer Ebene ergeben, die sich durch an der Verschlussvorrichtung ausgebildete Abdichtmittel, die zur Abdichtung auf einer Stirnfläche eines Behälters vorgesehen sind, ergibt.The total enclosed volume of the chamber may be up to 40% or more, for example 60% or even 80%, up to 95% of the total volume above a plane resulting from sealing means formed on the closure device for sealing on an end face a container are provided results.

Auch kann das erste Gewindemittel an der Kammer gesehen von der Gewindedrehachse radial nach außen weisend angeordnet sein. Die relative Bewegung der Kammer zu dem Innengehäuse kann durch korrespondierende, an der Kammer und dem Innengehäuse angeordnete Gewinde ermöglicht sein. Die Ausbildung der ersten Gewindemittel an der Kammer, gesehen von der Gewindedrehachse radial nach außen weisend, ermöglicht es, die Kammer inklusive des Gewindes innerhalb des Behälters anzuordnen. Dabei bleiben Kammer und Innengehäuse auch in der Ablassposition in Eingriff miteinander, so dass das Innengehäuse mit der an dem Deckelelement angeordneten Kammer von dem Behälter entfernt werden kann.Also, the first thread means may be disposed on the chamber as viewed from the thread rotation axis pointing radially outward. The relative movement of the chamber to the inner housing may be made possible by corresponding, arranged on the chamber and the inner housing thread. The formation of the first thread means on the chamber, as seen from the thread rotation axis radially outward, makes it possible to arrange the chamber including the thread within the container. Stick to it Chamber and inner housing in the discharge position in engagement with each other, so that the inner housing can be removed with the arranged on the lid member chamber from the container.

Durch die Verlagerung der ersten Gewindemittel in den Innenbereich des Behälters, hängt die Passform der Verschlussvorrichtung an dem Behälter nicht mehr von einer präzisen Dimensionierung des Behälters im Bereich der Behälteröffnung ab. Vielmehr kann die Dichtheit des mit der Verschlussvorrichtung geschlossenen Behälters auch sichergestellt werden, wenn der Behälter, insbesondere eine Glasflasche, Dimensionsabweichungen aufweist.As a result of the displacement of the first thread means into the interior region of the container, the fit of the closure device on the container no longer depends on a precise dimensioning of the container in the region of the container opening. Rather, the tightness of the container closed with the closure device can also be ensured if the container, in particular a glass bottle, has dimensional deviations.

Um etwaige Dimensionsabweichungen auszugleichen, kann zwischen dem Innengehäuse der Verschlussvorrichtung und der Innenwandung des Behälters im Bereich der Behälteröffnung besonders einfach eine vorzugsweise elastische Dichtung angeordnet werden.In order to compensate for any dimensional deviations, a preferably elastic seal can be arranged in a particularly simple manner between the inner housing of the closure device and the inner wall of the container in the region of the container opening.

Es kann vorgesehen sein, dass das Innengehäuse auf der dem ersten Gewinde abgewandten Seite eine Pressdichtung zur Anlage an einen Behälter im Bereich der Behälteröffnung aufweist. Diese Pressdichtung kann besonders vorteilhaft an das Innengehäuse angeschweißt sein. Durch die Elastizität der Pressdichtung können Dimensionsschwankungen bei der Herstellung der Glasflasche ausgeglichen werden, so dass die Verschlussvorrichtung die Behälteröffnung optimal abdichtet.It can be provided that the inner housing has on the side facing away from the first thread a press seal for engagement with a container in the region of the container opening. This press seal can be welded particularly advantageous to the inner housing. Due to the elasticity of the press seal dimensional variations in the manufacture of the glass bottle can be compensated so that the closure device seals the container opening optimally.

Es kann weiterhin vorgesehen sein, dass das Deckelelement ein zur Ausformung eines zweiten Gewindes an den Behälter angerolltes Aluminiumelement ist, wobei das an dem Deckelelement ausgeformte zweite Gewinde zu einem zweiten Gewinde des Behälters korrespondiert. Dabei wird das als Deckelelement dienende Aluminiumelement an die Außenwandung des Behälters im Bereich der Behälteröffnung angerollt, wodurch die Einprägung des Gewindes in das Deckelelement erfolgt. Deckelelement und Behälter sind somit formschlüssig korrespondierende Elemente, welche die Dichtheit des mit der Verschlussvorrichtung verschlossenen Behälters gewährleisten. Vorteilhaft ist dabei auch, dass bei der Herstellung des Deckelementes eine Technologie benutzt werden kann, welche bereits regelmäßig bei dem Verschließen von Glasflaschen mit Aluminiumdeckeln genutzt wird.It may further be provided that the cover element is an aluminum element which is rolled onto the container for the purpose of forming a second thread, wherein the second thread formed on the cover element corresponds to a second thread of the container. In this case, serving as a lid element aluminum element is rolled onto the outer wall of the container in the region of the container opening, whereby the impression of the thread is made in the lid member. Cover element and container are thus form-fitting corresponding elements, which the tightness of the closure device ensure closed container. It is also advantageous that in the production of the cover element, a technology can be used, which is already used regularly in the closing of glass bottles with aluminum lids.

Alternativ zu der zuvor dargestellten Ausbildung des Deckelelementes aus Aluminium schlägt die Erfindung vor, dass das Deckelelement ein Kunststoffelement ist, welches ein zu einem zweiten Gewinde des Behälters korrespondierendes zweites Gewinde aufweist. Gemäß dieser Ausführungsvariante wird das zweite Gewinde des Deckelelementes nicht erst bei der Verbindung mit dem Behälter ausgeprägt, sondern vielmehr bereits bei der Herstellung des Deckelelementes selbst, d. h. vor der endgültigen Montage an dem Behälter.As an alternative to the previously described embodiment of the cover element of aluminum, the invention proposes that the cover element is a plastic element which has a second thread corresponding to a second thread of the container. According to this embodiment, the second thread of the cover element is not pronounced only when it is connected to the container, but rather already in the production of the cover element itself, d. H. before final assembly to the container.

Wie bereits auch in Bezug auf das Aluminium-Deckelelement dargestellt, empfiehlt es sich auch in Verbindung mit dem Kunststoff-Deckelelement, dass das Innengehäuse auf der der Kammer abgewandten Seite eine Pressdichtung zur Anlage an dem Behälter im Bereich der Behälteröffnung aufweist. Insofern wird die notwendige Dichtheit des mit der Verschlussvorrichtung verschraubten Behälters sichergestellt.As already shown with respect to the aluminum cover element, it is also recommended in conjunction with the plastic cover element that the inner housing on the side facing away from the chamber has a press seal for engagement with the container in the region of the container opening. In this respect, the necessary tightness of the bolted to the closure device container is ensured.

Es kann zudem vorgesehen sein, dass an dem kragenförmig abgekanteten Randbereich der Kammer ein Folienelement zum Verschließen der Öffnung angeschweißt ist, welches Folienelement mit dem Deckelelement verbunden ist. Die Kammer ist erfindungsgemäß als einseitig offenes Behältnis ausgebildet, dessen Öffnung in zusammengebautem Zustand der Verschlussvorrichtung in Richtung des Deckelelementes weist. Diese Öffnung kann dazu verwendet werden, die Kammer auf einfache Art und Weise mit beispielsweise dem Verschlussmittel und Öffnungsmittel zu bestücken, so dass vor der Verbindung von Kammer und Deckelelement - wie auch zuvor in Bezug auf den Aluminiumdeckel möglich - eine fertig vormontierte "Kammereinheit" geschaffen wird, welche anschließend nur noch mit dem Deckelelement verbunden werden muss.It may also be provided that a film element for closing the opening is welded to the collar-shaped edge region of the chamber, which film element is connected to the cover element. According to the invention, the chamber is designed as a container open on one side, the opening of which in the assembled state of the closure device points in the direction of the cover element. This opening can be used to equip the chamber in a simple manner with, for example, the closure means and opening means, so that before the connection of the chamber and cover element - as previously possible with respect to the aluminum lid - a completely pre-assembled "chamber unit" is created, which then only has to be connected to the cover element.

Durch ein zwischen der Kammer und dem Deckelelement zusätzlich die Öffnung der Kammer fluiddicht verschließendes Folienelement kann auch die notwendige Dichtheit der Verschlussvorrichtung gewährleistet sein.By a between the chamber and the lid member in addition to the opening of the chamber fluid-tight closing foil element can also be ensured the necessary tightness of the closure device.

Auch kann vorgesehen sein, dass das Folienelement mit zumindest einem Teilbereich der Kammer und zumindest einem Teilbereich des Deckelelementes verschweißt ist. In Bezug auf einen Schweißvorgang kann vorgesehen sein, dass entweder alle drei Teile - Kammer, Folienelement, Deckelelement - im Wesentlichen an denselben Schweißpunkten, insbesondere auch zeitgleich, miteinander verschweißt werden, oder dass alternativ die Schweißpunkte örtlich abweichen. Letzteres bietet sich insbesondere an, wenn die Schmelzpunkte der Materialien von Deckelelement und Kammer so unterschiedlich sind, dass die Gefahr besteht, dass eines der Materialien über seinen Schmelzpunkt hinaus erhitzt wird. In diesem Fall empfiehlt es sich, die Schweißpunkte örtlich voneinander zu trennen. Beispielsweise können Deckelelement und Folienelement im Bereich der Öffnung der Kammer miteinander verschweißt werden, während Kammer und Folienelement im Bereich des kragenförmig abgekanteten Randbereiches der Kammer miteinander verschweißt werden.It can also be provided that the film element is welded to at least a portion of the chamber and at least a portion of the lid member. With regard to a welding process, it can be provided that either all three parts - chamber, film element, cover element - are welded together essentially at the same welding points, in particular also at the same time, or alternatively that the welding points deviate locally. The latter is especially useful when the melting points of the lid and chamber materials are so different that there is a risk that one of the materials will be heated above its melting point. In this case, it is advisable to separate the welding spots locally. For example, the cover element and the film element can be welded together in the region of the opening of the chamber, while the chamber and film element are welded together in the region of the collar-shaped folded edge region of the chamber.

Das Material des Deckelelementes ist regelmäßig PP (Polypropylen). PP weist einen Schmelzpunkt von ca. 210°C auf. Hingegen weist das Material der Kammer, PBT (Polybutylenterephthalat), einen Schmelzpunkt von ca. 320°C auf. Somit ist die für das Verschweißen von Kammer und Folienelement erforderliche Temperatur höher als die für das Verschweißen von Deckelelement und Folienelement erforderliche Temperatur. Die Kammer und das Folienelement sollten somit vorteilhaft unabhängig von dem Deckelelement miteinander verschweißt werden, so dass das Material des Deckelelementes nicht beeinträchtigt wird. Das Deckelelement und das Folienelement können dann zeitlich und örtlich separat miteinander verschweißt werden. Der Ort der Schweißverbindung von Deckelelement und Folienelement ist dann nicht auf den Bereich des kragenförmig abgekanteten Randbereiches festgelegt, sondern kann prinzipiell in dem gesamten Kontaktbereich von Deckelelement und Folienelement liegen, beispielsweise auch im Bereich der Öffnung der Kammer.The material of the cover element is regular PP (polypropylene). PP has a melting point of about 210 ° C. On the other hand, the material of the chamber, PBT (polybutylene terephthalate), has a melting point of about 320 ° C. Thus, the temperature required for the welding of the chamber and the film element is higher than the temperature required for the welding of the cover element and the film element. The chamber and the film element should thus advantageously be welded together independently of the cover element, so that the material of the cover element is not impaired. The cover element and the film element can then be welded together temporally and spatially separately. The location of the weld of lid element and film element is then not set to the region of the collar-shaped folded edge region, but can in principle be in the entire contact region of the cover element and the film element, for example, in the region of the opening of the chamber.

Das Folienelement ist bevorzugt eine Aluminiumfolie. Aluminiumfolien sind gas- und luftdicht, sowie nach Wärmebehandlung weich und biegsam. Daher bieten sie sich zur Verpackung von Lebensmitteln besonders an.The film element is preferably an aluminum foil. Aluminum foils are gas- and air-tight, as well as soft and flexible after heat treatment. Therefore, they are particularly suitable for the packaging of food.

Um die Haftung zwischen der Aluminiumfolie und der Kammer beziehungsweise der Aluminiumfolie und dem Deckelelement zu erhöhen, empfiehlt es sich zudem, dass die Aluminiumfolie mit einem Lack beschichtet ist. Der Lack ist in seiner Zusammensetzung auf das Material der Kammer beziehungsweise des Deckelelementes abzustimmen.In order to increase the adhesion between the aluminum foil and the chamber or the aluminum foil and the lid member, it is also recommended that the aluminum foil is coated with a lacquer. The paint is matched in its composition to the material of the chamber or the cover element.

Alternativ kann das Folienelement auch eine Kunststoffe aufweisende Mehrschichtfolie sein, wobei die Kunststoffe auf die Materialien des Deckelelementes und der Kammer angepasst sind. Für den Fall, dass das Deckelelement beispielsweise aus PP und die Kammer aus PBT hergestellt sind, bietet sich eine Mehrschichtfolie an, welche nacheinander die Schichten PP, EVOH, PBT aufweist. EVOH (Ethylen Vinylalkohol-Copolymer) ist ein zur Verpackung von Nahrungsmitteln regelmäßig eingesetztes Copolymer. Insbesondere bietet dieses eine Barriere für Sauerstoff und Kohlendioxid. Zwischen den Schichten aus PP und EVOH beziehungsweise EVOH und PBT kann zusätzlich ein Primer vorgesehen sein, welcher zusätzlich die Haftung zwischen den benachbarten Schichten erhöht.Alternatively, the film element can also be a multi-layer film comprising plastics, wherein the plastics are adapted to the materials of the cover element and the chamber. In the case where the cover element is made, for example, of PP and the chamber of PBT, a multilayer film is suitable which has the layers PP, EVOH, PBT in succession. EVOH (ethylene vinyl alcohol copolymer) is a copolymer used regularly for food packaging. In particular, this provides a barrier to oxygen and carbon dioxide. In addition, a primer may be provided between the layers of PP and EVOH or EVOH and PBT, which additionally increases the adhesion between the adjacent layers.

Sofern die Kammer in Abweichung von der Erfindung nicht mit einer Öffnung versehen ist, kann diese zur Verbindung mit dem Deckelelement alternativ auch von dem Material des Deckelelementes umspritzt sein.If, in deviation from the invention, the chamber is not provided with an opening, this may alternatively be encapsulated by the material of the cover element for connection to the cover element.

Zudem kann vorgesehen sein, dass die Kammer eine mit einem Verschlussmittel versehene Ablassöffnung aufweist, welche mittels eines an dem Innengehäuse angeordneten Öffnungsmittels öffenbar ist. Wie bereits im Stand der Technik bekannt, können diese korrespondierenden Verschlussmittel und Öffnungsmittel eine Membran und ein die Membran durchstoßender Dorn oder ein Schneidelement sein; alternativ können Verschlusselement und Öffnungsmittel jedoch auch als einteiliges Stopfenelement ausgebildet sein, welches abhängig von seiner Stellung innerhalb der Ablassöffnung einen Ablasskanal verschließt oder freigibt.In addition, it can be provided that the chamber has a drain opening provided with a closure means, which can be opened by means of an opening means arranged on the inner housing. As already known in the art, these corresponding closure means and opening means may be a membrane and a mandrel piercing the membrane or a cutting element; Alternatively, however, closure element and opening means may also be formed as a one-piece plug element, which closes or releases a discharge channel depending on its position within the discharge opening.

Bei einer Abgabe eines Mediums aus einer Verschlussvorrichtung wie zuvor dargestellt in einen Behälter weist die Verschlussvorrichtung jedenfalls ein Deckelelement zum Verschließen einer Behälteröffnung, eine an dem Deckelelement angeordnete Kammer und ein Innengehäuse auf. Bei einer Bewegung des Deckelelementes relativ zu dem Innengehäuse kommen korrespondierende, der Kammer und dem Innengehäuse zugeordnete Vorschlussmittel und Öffnungsmittel bei einer Bewegung des Deckelelementes relativ zu dem Innengehäuse so miteinander in Wechselwirkung, dass eine der Kammer zugeordnete Ablassöffnung freigegeben wird, so dass ein in der Kammer bevorratetes Medium in den Behälter austritt, wobei Kammer und Innengehäuse bei der Bewegung des Deckelelementes mittels an Kammer und Innengehäuse ausgebildeter korrespondierender erster Gewinde zueinander bewegt werden, wobei die Kammer mittels eines gesehen von einer Gewindedrehachse der Verschlussvorrichtung radial nach außen weisenden ersten Gewindes bewegt wird.In a delivery of a medium from a closure device as previously shown in a container, the closure device in any case, a cover member for closing a container opening, arranged on the lid member chamber and an inner housing. Upon movement of the lid member relative to the inner housing, corresponding confining means and opening means associated with the chamber and the inner housing interact with one another during movement of the lid member relative to the inner housing such that a discharge opening associated with the chamber is released, such that one in the chamber stockpiled medium exits into the container, wherein the chamber and inner housing are moved to each other during movement of the cover member by means formed on the chamber and inner housing corresponding first thread, wherein the chamber is moved by means of a viewed from a threaded axis of rotation of the closure device radially outwardly facing first thread.

Die im Stand der Technik zwischen Deckelelement und Innengehäuse erfolgende Drehbewegung erfolgt mittels an Kammer und Innengehäuse angeordnetem Gewinde. Diese Vorgehensweise ist insbesondere für Verschlussvorrichtungen an Glasbehältern vorteilhaft.The rotational movement taking place in the prior art between the cover element and the inner housing takes place by means of a thread arranged on the chamber and the inner housing. This procedure is particularly advantageous for closure devices on glass containers.

Beschreibung der AusführungsformenDescription of the embodiments

Dargestellt und beschrieben ist, zunächst mit Bezug zu Figur 1, eine Verschlussvorrichtung 1 nach einer ersten Ausführungsform mit einem Aluminium-Deckelelement 4 nach dem Anrollen an einen Behälter 2.Shown and described, first with reference to FIG. 1 , A closure device 1 according to a first embodiment with an aluminum cover element 4 after rolling against a container. 2

Die Verschlussvorrichtung ist vollständig vormontiert und an dem Behälter 2 angeschraubt, so dass eine Behälteröffnung 3 des Behälters 2 verschlossen ist. In diesem Zustand kann der Behälter 2 über längere Zeit gelagert werden, ohne dass der Inhalt aus dem Behälter 2 austreten kann. Durch das Anrollen an den Behälter 2 ist an dem Deckelelement 4 ein Gewinde ausgebildet, welches zu einem zweiten Gewinde 12 des Behälters 2 korrespondiert.The closure device is completely pre-assembled and screwed to the container 2, so that a container opening 3 of the container 2 is closed. In this state, the container 2 can be stored for a long time without the contents of the container 2 can escape. By rolling against the container 2, a thread is formed on the cover element 4, which corresponds to a second thread 12 of the container 2.

Die Verschlussvorrichtung 1 weist ein Deckelelement 4 auf, eine an dem Deckelelement 4 angeordnete Kammer 6 sowie ein Innengehäuse 5. In der gezeigten Ausführungsvariante ist das Deckelelement 4 ein Aluminiumdeckel.The closure device 1 has a cover element 4, a chamber 6 arranged on the cover element 4 and an inner housing 5. In the embodiment variant shown, the cover element 4 is an aluminum cover.

Das Innengehäuse 5 formt einen nach radial außen abragenden Flansch 22 aus, über welchen sich das Innengehäuse 5 unter Zwischenschaltung eines Abdichtmittels 23 auf einer Stirnfläche des Behälters 2 abstützt.The inner housing 5 forms a radially outwardly projecting flange 22, via which the inner housing 5 is supported with the interposition of a sealing means 23 on an end face of the container 2.

Kammer 6 und Deckelelement 4 können lediglich formschlussverbunden sein. Hierzu kann die Kammer 6 beziehungsweise das die Kammer 6 bildende Teil wandungsaußenseitig radial vorstehende Formschlussrippen 19 aufweisen, welche über den Umfang der Kammerwandung betrachtet zueinander beabstandet sind. Zufolge Anrollen des Deckelelement-Materials an die Kammeraußenwandung ergibt sich im Bereich der überfangenen Formschlussrippen 19 eine drehsichere Formschlussmitnahme, so dass ein Drehen des Deckelelementes 4 ein entsprechendes Mitdrehen der Kammer 6 beziehungsweise des die Kammer 6 bildenden Teils zur Folge hat.Chamber 6 and cover element 4 can only be positively connected. For this purpose, the chamber 6 or the chamber 6 forming part wall outside radially projecting form-fitting ribs 19 which are viewed over the circumference of the chamber wall spaced from each other. As a result of rolling the cover element material against the outer wall of the chamber, a rotationally secure form-locking engagement results in the area of the interlocking form-fitting ribs 19, so that rotation of the cover element 4 results in a corresponding turning of the chamber 6 or the part forming the chamber 6.

Das Drehen der Kammer 6 um die Gewindedrehachse 18 führt zu einer Linearverlagerung der Kammer 6 entlang der Gewindedrehachse 18, dies zufolge Eingriffs erster Gewindemittel 10, welche wandungsaußenseitig an der Kammer 6 ausgebildet sind, in ein entsprechend positioniertes Innengewinde eines Innengehäuses 5.The rotation of the chamber 6 about the thread rotation axis 18 leads to a linear displacement of the chamber 6 along the thread rotation axis 18, according to engagement of the first thread means 10, which are formed on the outer wall of the chamber 6, in a correspondingly positioned internal thread of an inner housing. 5

Die Kammer 6 erstreckt sich oberhalb des ersten Gewindemittels 10, weiter in Nutzungsstellung oberhalb eines die Behälteröffnungen 3 umgebenden Behälterrandes seitlich bis über die ersten Gewindemittel 10 hinaus. In diesem radial erweiterten ersten Bereich A weist die Kammer 6 etwa einen an den Behälterhals-Außendurchmesser angepassten Durchmesser auf. Weiter kann der Außendurchmesser des ersten Kammerbereichs A etwa dem Durchmesser im Gewindegrund des zweiten Gewindes 12 entsprechen.The chamber 6 extends above the first thread means 10, further in use position, above a container rim surrounding the container openings 3, laterally beyond the first thread means 10. In this radially expanded first region A, the chamber 6 has approximately a diameter adapted to the container neck outer diameter. Furthermore, the outer diameter of the first chamber region A can correspond approximately to the diameter in the thread root of the second thread 12.

In axialer Richtung erstreckt sich dieser radial erweiterte erste Bereich A über ein axiales Maß, das etwa einem Viertel bis einem Drittel bis hin zur Hälfte der axialen Länge des radial reduzierten zweiten Bereiches B der Kammer 6 d.h. insbesondere eines Bereiches der Kammer, welcher dem Behälterhals zugeordnet ist, entspricht. Der radial kleinere Bereich B kann in Bezug auf die Gewindemittel 10 oberhalb und/oder unterhalb dieser Gewindemittel 10 wie auch in horizontaler Überdeckung zu diesen ersten Gewindemitteln 10 ausgebildet sein..In the axial direction, this radially expanded first region A extends over an axial dimension that is approximately one-quarter to one-third to one-half the axial length of the radially reduced second region B of the chamber 6, i. in particular a region of the chamber which is associated with the container neck corresponds. The radially smaller region B may be formed with respect to the thread means 10 above and / or below this thread means 10 as well as in horizontal overlap to these first thread means 10 ..

Der die Bereiche A und B verbindende Erweiterungsbereich 28 kann stufenartig ausgebildet sein oder, wie bspw. in den Figuren 11 bis 13 dargestellt, konisch sich nach vertikal unten und radial innen verjüngend.The expansion area 28 connecting the areas A and B may be step-like or, for example, in the FIGS. 11 to 13 shown conically tapering vertically downwards and radially inside.

Hierdurch ist eine Volumenvergrößerung der Kammer 6 bei gleichem Behälterhals-Innendurchmesser erreicht.As a result, an increase in volume of the chamber 6 is achieved at the same container neck inner diameter.

Insbesondere zufolge des Anrollens der deckelelementsartigen Hülsenwandung an dem Behälterhals ergibt sich unterhalb des Kammer-Erweiterungsbereiches eine Wandungseinschnürung 24, die den Erweiterungsbereich randseitig untergreift.In particular, due to the curling of the cover element-like sleeve wall on the container neck results below the chamber extension region a Wandungseinschnürung 24, which engages under the extension area edge.

Weiter weist die Kammer 6 - bezogen auf eine Nutzungsstellung gemäß Figur 1- oberseitig der ersten Gewindemittel 10 in Zuordnungsstellung, weiter bevorzugt oberseitig der freien Stirnfläche der Behälteröffnung 3, d.h. bevorzugt im radial erweiterten Kammerbereich A, eine horizontale Teilung T auf.Next, the chamber 6 - based on a use position according to FIG. 1 - Upper side of the first thread means 10 in assignment position, more preferably on the upper side of the free end face of the container opening 3, ie preferably in the radially widened chamber area A, a horizontal pitch T.

Die Kammer 6 ist so in ein Kammer-Unterteil 6' und ein Kammer-Oberteil 6" unterteilt, wobei das Kammer-Oberteil 6" insbesondere nach Befüllen der Kammer 6 mit der Flüssigkeit deckelartig auf das Kammer-Unterteil 6' aufsetzbar ist. Es kann hier eine Rastverbindung vorliegen. Auch kann diesbezüglich eine Verschweißung oder Verklebung vorgesehen sein.The chamber 6 is subdivided into a chamber lower part 6 'and a chamber upper part 6 ", wherein the chamber upper part 6" can be placed on the chamber lower part 6', in particular after filling the chamber 6 with the liquid. There may be a detent connection here. Also may be provided in this regard a welding or bonding.

Die Formschlussrippen 19 können wandungsaußenseitig an dem Kappen-Oberteil 6" ausgeformt sein.The form-fitting ribs 19 may be formed on the outside of the cap 6 'on the outside of the hood.

Ein zur Zusammenwirkung mit dem fußseitigen Kammer-Auslassbereich ausgebildetes Verschlussmittel 7 kann im 2-Komponenten-Spritzverfahren hergestellt sein, so insbesondere mit einem radial inneren Hartkunststoff 21 und einem radial äußeren Weichkunststoff 20.A closure means 7 designed to cooperate with the foot-side chamber outlet region can be produced in a 2-component injection molding process, in particular with a radially inner hard plastic 21 and a radially outer soft plastic 20.

Das Verschlussmittel 7 kann wandungsaußenseitig vollständig vom Weichkunststoff 20 umfasst sein, so dass auch eine dem Kammerinneren zugewandte Stirnfläche des Verschlussmittels 7 aus einem Weichkunststoff 20 gebildet ist.The closing means 7 can be completely surrounded by the soft plastic 20 on the outside of the wall so that an end face of the closing means 7 facing the interior of the chamber is formed of a soft plastic 20.

Der Weichkunststoff 20 kann, wie bevorzugt, Dichtungseigenschaften aufweisen, insbesondere in Zusammenwirkung des Verschlussmittels 7 mit öffnungsseitigen Wandungsabschnitten der Kammer 6.The soft plastic 20 can, as preferred, have sealing properties, in particular in cooperation of the closure means 7 with opening-side wall sections of the chamber 6.

Bezüglich der weiteren Ausgestaltung und Funktionsweise der Verschlussvorrichtung 1 der ersten Ausführungsform (Figuren 1 bis 4) wird auch auf die nachstehenden Ausführungen verwiesen.With respect to the further embodiment and mode of operation of the closure device 1 of the first embodiment ( FIGS. 1 to 4 ) is also referred to the following remarks.

Figur 5 zeigt eine Verschlussvorrichtung 1 gemäß der Erfindung mit einem Aluminium-Deckelelement 4 vor dem Anrollen an einen Behälter 2. Das Deckelelement 4 weist in Bezug auf eine an einen Behälter 2. anzulegende Außenwandung noch kein Gewinde auf. FIG. 5 shows a closure device 1 according to the invention with an aluminum cover member 4 before rolling against a container 2. The cover member 4 has in relation to a to be applied to a container second outer wall not yet thread.

Figur 6 zeigt die Verschlussvorrichtung 1 gemäß Figur 5 nach dem Anrollen an einen Behälter 2. Die Verschlussvorrichtung 1 ist vollständig vormontiert und an einem Behälter 2 angeschraubt. FIG. 6 shows the closure device 1 according to FIG. 5 after rolling against a container 2. The closure device 1 is completely pre-assembled and screwed to a container 2.

Die Verschlussvorrichtung 1 weist ein Deckelelement 4 auf, eine an dem Deckelelement 4 angeordnete Kammer 6 sowie ein Innengehäuse 5. In der gezeigten Ausführungsvariante ist das Deckelelement 4 ein Aluminiumdeckel. Das Deckelelement 4 ist an die Kammer 6 angeschweißt. Die Kammer 6 kann beispielsweise aus einem Kunststoff, wie PBT (Polybutylenterephthalat) ausgebildet sein. Um die Kammer 6 mit dem Deckelelement 4 aus Aluminium verschweißen zu können, empfiehlt sich für das Deckelelement 4 ein Aluminium mit einem Lack für PBT. Die Kammer 6 weist in deren in Richtung des Deckelelementes 4 gerichteten Bereich eine Öffnung 13 auf, welche vor der Bedeckung mit dem Deckelelement 4 genutzt werden kann, um weitere Elemente der Verschlussvorrichtung 1 zu montieren. Bei diesen Elementen kann es sich beispielsweise um Verschlussmittel 7 und Öffnungsmittel 9 zum Verschluss beziehungsweise Öffnen einer in der Kammer 6 angeordneten Ablassöffnung 8 handeln. Die Ablassöffnung 8 ist vorteilhaft von dem Deckelelement 4 weg gerichtet (in Bezug auf die in Figur 6 dargestellte Verschlussvorrichtung 1 "nach unten").The closure device 1 has a cover element 4, a chamber 6 arranged on the cover element 4 and an inner housing 5. In the embodiment variant shown, the cover element 4 is an aluminum cover. The lid member 4 is welded to the chamber 6. The chamber 6 may for example be formed from a plastic, such as PBT (polybutylene terephthalate). In order to be able to weld the chamber 6 to the cover element 4 made of aluminum, an aluminum with a lacquer for PBT is recommended for the cover element 4. The chamber 6 has in its direction in the direction of the lid member 4 directed area an opening 13 which can be used before the cover with the cover member 4 to mount other elements of the closure device 1. These elements may be, for example, closure means 7 and opening means 9 for closing or opening a discharge opening 8 arranged in the chamber 6. The discharge opening 8 is advantageously directed away from the cover element 4 (with respect to FIGS FIG. 6 Shutter device 1 shown "down").

Die Kammer 6 weist im Bereich der Öffnung 13 einen kragenförmig abgekanteten Randbereich 14 auf. An diesen Randbereich 14 kann das Deckelelement 4 angeschweißt werden.The chamber 6 has in the region of the opening 13 on a collar-shaped folded edge region 14. At this edge region 14, the lid member 4 can be welded.

Die Kammer 6 ist mittels korrespondierender erster Gewindemittel 10 mit dem Innengehäuse 5 verbunden. Dabei ist das erste Gewindemittel 10 betrachtet von einer Gewindedrehachse 18 der Verschlussvorrichtung radial nach außen weisend an der Kammer 6 angeordnet. Das bedeutet, dass das erste Gewindemittel 10 bezogen auf eine vertikale Projektion in Richtung der Gewindedrehachse 18 radial außerhalb zu der Kammer 6 und innerhalb des Innengehäuses 5 ausgebildet ist. Das Innengehäuse 5 ist mittels einer Pressdichtung 11 in den Behälter 2 im Bereich der Behälteröffnung 13 gepresst. Das Deckelelement 4 und der Behälter 2 weisen darüber hinaus korrespondierende zweite Gewinde 12 auf, mittels welcher das Deckelelement 4 mit dem Behälter 2 verbunden ist.The chamber 6 is connected by means of corresponding first thread means 10 with the inner housing 5. In this case, the first thread means 10, viewed from a thread rotation axis 18 of the closure device, is arranged radially outwardly facing the chamber 6. This means that the first thread means 10 is formed with respect to a vertical projection in the direction of the thread rotation axis 18 radially outside the chamber 6 and inside the inner housing 5. The inner housing 5 is pressed by means of a press seal 11 into the container 2 in the region of the container opening 13. The cover element 4 and the container 2 furthermore have corresponding second threads 12, by means of which the cover element 4 is connected to the container 2.

Weiter weist die Kammer 6 in einem Querschnitt quer zu der Gewindedrehachse 18 den flanschartig nach radial außen ragenden Randbereich 14 auf, wobei das erste Gewindemittel 10 bezüglich einer Außenkante des Randbereichs 14 radial innen ausgebildet ist.Next, the chamber 6 in a cross-section transverse to the thread rotation axis 18 to the flange radially outwardly projecting edge portion 14, wherein the first thread member 10 is formed radially inwardly with respect to an outer edge of the edge portion 14.

Die Herstellung der vorgenannten Verschlussvorrichtung 1 sowie deren Anordnung an dem Behälter 2 erfolgt beispielsweise so, dass zuerst die Kammer 6 mit den die Ablassöffnung 8 der Kammer 6 verschließenden beziehungsweise öffnenden Verschlussmitteln 7 beziehungsweise Öffnungsmitteln 9 bestückt wird. Im hier gezeigten Beispiel sind Verschlussmittel 7 und Öffnungsmittel 9 als ein einstückig ausgebildetes Stopfenelement ausgebildet, welches in die Ablassöffnung 8 der Kammer 6 eingebracht ist. Der in Richtung des Deckelelementes 4 weisende Teilbereich, d.h. das Verschlussmittel 7, ist so geformt, dass es je nach der Stellung innerhalb der Ablassöffnung 8 diese Ablassöffnung 8 entweder verschließt oder einen Ablasskanal 16 freigibt, durch welchen das in der Kammer 6 befindliche Medium in den Behälter 2 ausströmen kann. Das Öffnungsmittel 9, welches von dem Deckelelement 4 weggerichtet ist, weist einen Ablasskanal 16 auf, durch welchen das Medium in den Behälter 2 strömen kann. Das Öffnungsmittel 9 ist mit dem Innengehäuse 5 verbunden. Im hier gezeigten Beispiel ist ein an dem Öffnungsmittel 9 ausgebildeter Randbereich von dem Material des Innengehäuses 5 umspritzt. Alternativ könnte es sich hier jedoch auch um eine Presspassung handeln.The aforementioned closure device 1 and its arrangement on the container 2 are produced, for example, such that first the chamber 6 is equipped with the closure means 7 or opening means 9 closing or opening the discharge opening 8 of the chamber 6. In the example shown here, closing means 7 and opening means 9 are designed as an integrally formed plug element, which is introduced into the discharge opening 8 of the chamber 6. The partial region pointing in the direction of the cover element 4, ie the closure means 7, is shaped such that it either closes this discharge opening 8 or releases a discharge channel 16, depending on the position within the discharge opening 8, through which the medium located in the chamber 6 enters into the chamber Outlet container 2 can. The opening means 9, which is directed away from the cover element 4, has a discharge channel 16, through which the medium can flow into the container 2. The opening means 9 is connected to the inner housing 5. In the example shown here, an edge region formed on the opening means 9 is encapsulated by the material of the inner housing 5. Alternatively, however, this could also be a press fit.

Nach abgeschlossener Vorbereitung der Kammer 6 wird diese mit dem Deckelelement 4 durch Schweißen verbunden, wodurch gleichzeitig die Öffnung 13 der Kammer 6 verschlossen wird. Dabei wird der abgekantete Randbereich 14 der Kammer 6 mit dem Deckelelement 4 verschweißt. In diesem Zustand handelt es sich bei dem Deckelelement 4 noch um eine Art Rohling, der noch kein zweites Gewinde 12 zur Verbindung mit dem Behälter 2 aufweist. In einem nachfolgenden Schritt wird das Innengehäuse 5 über die Behälteröffnung 3 in den Behälter 2 eingelassen. Dabei wird das Innengehäuse 5 mitsamt einer an dem Innengehäuse 5 angeordneten Pressdichtung 11 in die Behälteröffnung 3 gepresst. Schließlich wird die Kammer 6 mit dem daran angeordneten Deckelelement 4 in das Innengehäuse 5 eingebracht, wobei Kammer 6 und Innengehäuse 5 mittels der korrespondierenden ersten Gewindemittel 10 miteinander verschraubt werden. Während dieser Schraubbewegung wird gleichzeitig auch das Deckelelement 4 an das zweite Gewinde 12 des Behälters 2 angerollt, wobei sich in dem Deckelelement 4 ebenfalls ein zweites Gewinde 12 ausbildet.After completion of the preparation of the chamber 6, this is connected to the lid member 4 by welding, whereby at the same time the opening 13 of the chamber 6 is closed. In this case, the folded edge region 14 of the chamber 6 is welded to the cover element 4. In this state, the cover element 4 is still a kind of blank which does not yet have a second thread 12 for connection to the container 2. In a subsequent step, the inner housing 5 is let into the container 2 via the container opening 3. In this case, the inner housing 5 together with a pressure seal 11 arranged on the inner housing 5 is pressed into the container opening 3. Finally, the chamber 6 is introduced with the cover element 4 disposed thereon in the inner housing 5, wherein the chamber 6 and the inner housing 5 by means of the corresponding first thread means 10 are screwed together. During this screwing movement, the cover element 4 is also rolled onto the second thread 12 of the container 2 at the same time, wherein a second thread 12 likewise forms in the cover element 4.

Alternativ zu der zuvor dargestellten Herstellungsweise kann die Verschweißung von Kammer 6 und Deckelelement 4 auch erst dann erfolgen, wenn das Deckelelement 4 mit dem Behälter 2 verschraubt ist.As an alternative to the method of preparation described above, the welding of chamber 6 and cover element 4 can also take place only when the cover element 4 is screwed to the container 2.

Für die Verbindung von Kammer 6 und Deckelelement 4 kann es zusätzlich vorteilhaft sein, den abgekanteten Randbereich 14 in Bezug auf seine radiale Dimension so auszubilden, dass dieser über die Oberfläche des Behälters 2 hervorsteht, so dass sich im Bereich der Behälteröffnung 3 ein Vorsprung 17 ergibt.For the connection of chamber 6 and cover element 4, it may additionally be advantageous to design the beveled edge region 14 with respect to its radial dimension so that it projects beyond the surface of the container 2, so that a projection 17 results in the region of the container opening 3 ,

Bei dem Anrollen des Deckelelementes 4 an den Behälter 2 legt sich das Material des Deckelelementes 4 über diesen Vorsprung 17, so dass hierdurch zusätzlich die Verbindung gestärkt wird.When rolling the lid member 4 to the container 2, the material of the lid member 4 lays over this projection 17, so that in addition the connection is strengthened.

Figur 7 zeigt eine alternative Ausführungsform einer erfindungsgemäßen Verschlussvorrichtung 1. Das Deckelelement 4 dieser Verschlussvorrichtung 1 besteht vorzugsweise aus einem Kunststoff, beispielsweise PP (Polypropylen) oder PE (Polyethylen). Der grundsätzliche Aufbau der Verschlussvorrichtung 1 ist ähnlich zu der in Figur 5 dargestellten. Da das Deckelelement 4 jedoch nicht aus Aluminium besteht, sondern vielmehr aus einem Kunststoff, ist ein Anrollen des Deckelelementes 4 an den Behälter 2 nicht möglich. FIG. 7 shows an alternative embodiment of a closure device according to the invention 1. The cover element 4 of this closure device 1 is preferably made of a plastic, for example PP (polypropylene) or PE (polyethylene). The basic structure of the closure device 1 is similar to that in FIG FIG. 5 shown. However, since the lid member 4 is not made of aluminum, but rather of a plastic, rolling up of the lid member 4 to the container 2 is not possible.

Gemäß Figur 7 ist die Kammer 6 im Bereich ihrer Öffnung 13 mit einem Folienelement 15 verschlossen. Dieses Folienelement 15 ist vorteilhaft eine Aluminiumfolie, kann jedoch auch aus einem Kunststoffmaterial, beispielsweise EVOH (Ethylen Vinylalkohol-Copolymer), PET (Polyethylenterephthalat) oder ähnliches, bestehen. In dem Falle, dass das Folienelement 15 aus Aluminum besteht, ist dieses vorzugsweise auf der in Richtung der Kammer 6 weisenden Seite mit einem Lack für das Material der Kammer 6, insbesondere PBT, beschichtet. Auf der entgegengesetzten, in Richtung des Deckelelements 4 weisenden Seite des Folienelementes 15 ist vorteilhaft ein Lack aufgebracht, welcher sich zur Verbindung mit dem Deckelelement 4 eignet. Sofern das Deckelelement 4 beispielsweise aus PP besteht, empfiehlt sich ein Lack für PP. In einem folgenden Verfahrensschritt wird das Folienelement 15 an die Kammer 6 beziehungsweise das Deckelelement 4 angeschweißt. Das Verschweißen kann entweder in einem gemeinsamen Verfahrensschritt erfolgen, oder in aufeinanderfolgenden Schritten, wobei das Folienelement 15 beispielsweise zuerst an die Kammer 6 angeschweißt wird, und erst in einem darauffolgenden Schritt an das Deckelelement 4.According to FIG. 7 the chamber 6 is closed in the region of its opening 13 with a film element 15. This film element 15 is advantageously an aluminum foil, but may also consist of a plastic material, for example EVOH (ethylene vinyl alcohol copolymer), PET (polyethylene terephthalate) or the like. In the case that the film element 15 is made of aluminum, this is preferably coated on the facing in the direction of the chamber 6 side with a paint for the material of the chamber 6, in particular PBT. On the opposite, in the direction of the lid member 4 facing side of the film element 15, a paint is advantageously applied, which is suitable for connection to the cover element 4. If the cover element 4 is made of PP, for example, a paint for PP is recommended. In a subsequent method step, the film element 15 is welded to the chamber 6 or the cover element 4. The welding can take place either in a common process step, or in successive steps, wherein the film element 15, for example, first welded to the chamber 6, and only in a subsequent step to the lid member 4th

Im Übrigen weist die Verschlussvorrichtung 1 gemäß Figur 7 bereits ein an dem Deckelelement 4 ausgebildetes zweites Gewinde 12 zur Verbindung mit dem Behälter 2 auf.Otherwise, the closure device 1 according to FIG FIG. 7 already formed on the lid member 4 second thread 12 for connection to the container 2.

Die Verschlussvorrichtungen 1 gemäß den Figuren 6 und 7 sind in einer Schließposition dargestellt. Dabei ist der Behälter 2 fluiddicht mit der Verschlussvorrichtung 1 verbunden, d.h. das Verschlussmittel 7 befindet sich so innerhalb der Ablassöffnung 8 der Kammer 6, dass das in der Kammer 6 bevorratete Medium nicht durch den Ablasskanal 16 abfließen kann, sondern vielmehr in der Kammer 6 eingeschlossen ist.The closure devices 1 according to the FIGS. 6 and 7 are shown in a closed position. In this case, the container 2 is connected in a fluid-tight manner to the closure device 1, ie, the closure means 7 is located within the discharge opening 8 of the chamber 6 so that the medium stored in the chamber 6 can not flow away through the discharge channel 16, but rather is enclosed in the chamber 6 is.

Um nun das in der Kammer 6 bevorratete Medium in den Behälter 2 zu geben, ist es erforderlich, die Verschlussvorrichtung 1 in eine Ablassposition zu bringen. Die dafür zu unternehmenden Schritte werden im Folgenden näher erläutert.In order now to give the stored in the chamber 6 medium in the container 2, it is necessary to bring the closure device 1 in a discharge position. The steps to be taken are explained in more detail below.

Figur 8 zeigt beispielsweise die Verschlussvorrichtung 1 gemäß Figur 6 in einer Ablassposition. Obwohl die Ablassposition hier in Bezug auf Figur 6 dargestellt wird, kann diese genauso bei einer Verschlussvorrichtung 1 gemäß Figur 7 ausgeführt sein. Die Verschlussvorrichtung 1 gemäß Figur 8 dient somit nur als Ausführungsbeispiel für die Ablassposition und ist in keinster Weise beschränkend. FIG. 8 shows, for example, the closure device 1 according to FIG. 6 in a discharge position. Although the discharge position here in terms of FIG. 6 is shown, this can just as in a closure device 1 according to FIG. 7 be executed. The closure device 1 according to FIG. 8 thus serves only as an exemplary embodiment of the discharge position and is in no way limiting.

Wie in Figur 8 dargestellt, sind zur Verwirklichung einer Ablassposition das Deckelelement 4 und der Behälter 2 voneinander zu entfernen. Durch diese longitudinale Verschiebung von Deckelelement 4 und Behälter 2 werden gleichzeitig auch die an dem Deckelelement 4 angeordnete Kammer 6 und das an dem Behälter 2 angeordnete Innengehäuse 5 zueinander verschoben. Da das Verschlussmittel 7 beziehungsweise das Öffnungsmittel 9 an dem Innengehäuse 5 angeordnet sind, erfolgt durch die Verschiebung der Kammer 6 relativ zu dem Innengehäuse 5 gleichzeitig auch eine Verschiebung des Verschlussmittels 7 beziehungsweise des Öffnungsmittels 9 innerhalb der Ablassöffnung 8 der Kammer 6. Dadurch kommt es zu der Freigabe der Ablassöffnung 8, so dass das innerhalb der Kammer 6 bevorratete Medium durch die Ablassöffnung 8 und den innerhalb des Öffnungsmittels 9 ausgebildeten Ablasskanal 16 in den Behälter 2 fließen kann.As in FIG. 8 are shown, in order to achieve a discharge position, the lid member 4 and the container 2 to be removed from each other. As a result of this longitudinal displacement of the cover element 4 and the container 2, the chamber 6 arranged on the cover element 4 and the inner housing 5 arranged on the container 2 are simultaneously displaced relative to one another. Since the closure means 7 and the opening means 9 are arranged on the inner housing 5, carried by the displacement of the chamber 6 relative to the inner housing 5 at the same time a displacement of the closure means 7 and the opening means 9 within the discharge opening 8 of This results in the release of the discharge opening 8, so that the medium stored within the chamber 6 can flow through the discharge opening 8 and the discharge channel 16 formed within the opening means 9 into the container 2.

Um eine longitudinale Bewegung zwischen dem Deckelelement 4 und dem Behälter 2 hervorzurufen, werden die an dem Deckelelement 4 und dem Behälter 2 ausgebildeten korrespondierenden zweiten Gewinde 12 zueinander rotiert. Durch diese Rotation kommt es gleichzeitig zu einer Rotation der Kammer 6 innerhalb des Innengehäuses 5. Diese Rotation wird durch die an Kammer 6 und Innengehäuse 5 ausgebildeten ersten Gewindemittel 10 ermöglicht. Dadurch, dass das Innengehäuse 5 mittels der Pressdichtung 11 fest in dem Behälter 2 eingepresst ist, bleibt das Innengehäuse 5 während des Abschraubens des Deckelelementes 4 von dem Behälter 2 beziehungsweise der Rotation der Kammer 6 innerhalb des Innengehäuses 5 fest mit dem Behälter 2 verbunden. Erst wenn das erste Gewindemittel 10 der Kammer 6 einen Endbereich des ersten Gewindes 10 des Innengehäuses 5 erreicht hat, kommt es zu einer Arretierung der korrespondierenden ersten Gewindemittel 10, wodurch sich bei einem weiteren Abschrauben des Deckelelementes 4 von dem Behälter 2 mit dem Herauslösen der an dem Deckelelement 4 befestigten Kammer 6 aus dem Behälter 2 gleichzeitig auch das Innengehäuse 5 aus dem Behälter 2 löst. Dabei wird die an dem Innengehäuse 5 angeordnete Pressdichtung 11 ebenfalls aus dem Behälter 2 gelöst wird. Die Anpresskraft der Pressdichtung 11 innerhalb des Behälters 2 wird überwunden.In order to cause a longitudinal movement between the lid member 4 and the container 2, the corresponding second threads 12 formed on the lid member 4 and the container 2 are rotated relative to each other. As a result of this rotation, the chamber 6 within the inner housing 5 simultaneously rotates. This rotation is made possible by the first thread means 10 formed on the chamber 6 and the inner housing 5. Due to the fact that the inner housing 5 is pressed firmly into the container 2 by means of the press seal 11, the inner housing 5 remains firmly connected to the container 2 during the unscrewing of the cover element 4 from the container 2 or the rotation of the chamber 6 within the inner housing 5. Only when the first thread means 10 of the chamber 6 has reached an end portion of the first thread 10 of the inner housing 5, there is a locking of the corresponding first thread means 10, resulting in a further unscrewing of the cover member 4 of the container 2 with the dissolution of the the lid member 4 fixed chamber 6 from the container 2 at the same time the inner housing 5 from the container 2 dissolves. In this case, the pressure seal 11 arranged on the inner housing 5 is likewise released from the container 2. The contact pressure of the press seal 11 within the container 2 is overcome.

Während des Abschraubvorgangs wird die Kammer 6 zuerst einmal relativ zu dem Innengehäuse 5 bewegt, so dass sich die Kammer 6 gleichzeitig an dem mit dem Innengehäuse 5 verbundenen Verschlussmittel 7 bzw. Öffnungsmittel 9 vorbeibewegt. Dabei wird zwischen Verschlussmittel 7 und Innengehäuse 5 ein Teilbereich der Ablassöffnung 8 geöffnet, so dass das in der Kammer 6 bevorratete Medium durch den Ablasskanal 16 des Öffnungsmittels 9 in den Behälter 2 fließen kann.During the unscrewing operation, the chamber 6 is first moved once relative to the inner housing 5, so that the chamber 6 simultaneously moves past the closure means 7 or opening means 9 connected to the inner housing 5. In this case, a partial region of the discharge opening 8 is opened between the closure means 7 and the inner housing 5, so that the medium stored in the chamber 6 can flow into the container 2 through the discharge channel 16 of the opening means 9.

Figur 9 zeigt eine nachfolgende Stellung: Bei voranschreitender Anhebung der Kammer 6 kann das Verschlussmittel 7 mit seinem oberen Endbereich in eine Stellung zu der Ablassöffnung 8 gelangen, in welcher die Ablassöffnung 8 wieder verschlossen wird, so dass ein Nachtropfen von Medium aus der Kammer 6 verhindert wird. Hierzu ist der obere Endbereich des Verschlussmittels 7 regelmäßig gegenüber den benachbarten Bereichen des Verschlussmittels 7 radial erweitert. Diese Stellung ist optional. Schließlich trennen sich die zweiten Gewinde 12 des Deckelelementes 4 und des Behälters 2 voneinander, während sich die ersten Gewindemittel 10 der Kammer 6 und des Innengehäuses 5 in einer Endstellung befinden. Kammer 6 und Innengehäuse 5 können sich in dieser Endstellung nicht weiter zueinander verdrehen. FIG. 9 shows a subsequent position: With advancing raising the chamber 6, the closure means 7 can reach with its upper end portion in a position to the discharge opening 8, in which the discharge opening 8 is closed again, so that a dripping of medium from the chamber 6 is prevented. For this purpose, the upper end region of the closure means 7 is regularly radially widened relative to the adjacent regions of the closure means 7. This position is optional. Finally, the second threads 12 of the lid member 4 and the container 2 separate from each other, while the first thread means 10 of the chamber 6 and the inner housing 5 are in an end position. Chamber 6 and inner housing 5 can not turn each other in this end position.

Figur 10 zeigt die vollständig von dem Behälter 2 entfernte Verschlussvorrichtung 1. Das Verschlussmittel 7 sichert die Ablassöffnung 8 der Kammer 6 gegen ein Nachtropfen des Mediums aus der Kammer 6. FIG. 10 shows the completely removed from the container 2 closure device 1. The closure means 7 secures the discharge opening 8 of the chamber 6 against dripping of the medium from the chamber. 6

Figur 11 zeigt eine nicht erfindungsgemäße Ausführungsform, aufbauend auf der in Figur 1 dargestellten Ausführung, wobei dieser gegenüber das Volumen des Erweiterungsbereiches (erster Kammerbereich A) vergrößert ist. Dies ist erreicht zufolge einer gegenüber der Version in Fig. 1 in vertikaler Richtung, das heißt entlang der Gewindedrehachse 18 gewählten Vergrößerung, insbesondere der Wandung des Kammer-Oberteils 6". FIG. 11 shows a non-inventive embodiment, based on the in FIG. 1 illustrated embodiment, wherein this compared to the volume of the extension region (first chamber area A) is increased. This is achieved according to one of the version in Fig. 1 in the vertical direction, that is along the thread rotation axis 18 chosen magnification, in particular the wall of the chamber upper part 6 ".

Ergibt sich in dem Ausführungsbeispiel gemäß Figur 1 ein Volumenanteil von etwa 60% im ersten Bereich A gegenüber dem Gesamtvolumen, so ergibt sich in der Ausführungsform gemäß Figur 11 ein Teilvolumen im ersten Bereich A von etwa 80%, dies bei bevorzugt gleichem Außendurchmesser im Erweiterungsbereich.It follows in the embodiment according to FIG. 1 a volume fraction of about 60% in the first region A compared to the total volume, it follows in the embodiment according to FIG. 11 a partial volume in the first region A of about 80%, this at preferably the same outer diameter in the extension region.

Der zweite Bereich B geht - mit Bezug auch auf die dargestellte Ventilverschlussstellung - etwa auf Höhe des innengehäuseseitigen Flansches 22 - über in einen Konusbereich 25 (Erweiterungsbereich 28). Der Konusbereich 25 erweitert sich ausgehend von dem zweiten Bereich B nach radial außen und im üblichen Nutzungszustand nach vertikal oben. Im Bereich des umlaufenden freien Randes des Konusbereiches 25 ist das Kammer-Oberteil 6" festgelegt.The second region B passes - with reference also to the illustrated valve closure position - approximately at the level of the inner housing-side flange 22 - over into a cone region 25 (extension region 28). The cone area 25 extends starting from the second region B radially outward and in the usual state of use to vertically above. In the area of the circumferential free edge of the cone region 25, the chamber upper part 6 "is fixed.

Der Konusbereich 25 ist über eine oder mehrere Streben 26 entweder unmittelbar auf dem auch die Stirnfläche des Behälters 2 übergreifenden Flansch 22 abgestützt und/oder auf einem Flanschabschnitt 27 der Kammer 6 bzw. des Kammer-Unterteiles 6', welcher sich in der Grundstellung gemäß Figur 11 auf dem Flansch 22 abstützt.The cone region 25 is supported by one or more struts 26 either directly on the also the end face of the container 2 cross-flange 22 and / or on a flange 27 of the chamber 6 and the chamber lower part 6 ', which in the basic position shown in FIG 11 supported on the flange 22.

Figur 12 zeigt eine weitere alternative Ausführungsform einer Verschlussvorrichtung 1. Das Deckelelement 4 dieser Verschlussvorrichtung 1 besteht vorzugsweise aus einem Kunststoff, beispielsweise Polypropylen oder Polyethylen. Der grundsätzliche Aufbau der Verschlussvorrichtung 1 ist ähnlich zu der in Figur 11 dargestellten. Da das Deckelelement 4 jedoch nicht aus Aluminium besteht, sondern vielmehr aus einem Kunststoff, ist ein Anrollen des Deckelelementes 4 an dem Behälter 2 nicht möglich. Vielmehr ist an dem Deckelelement 4 unmittelbar ein zu dem zweiten Gewinde 12 ausgebildetes Gegengewinde vorgesehen. FIG. 12 shows a further alternative embodiment of a closure device 1. The cover element 4 of this closure device 1 is preferably made of a plastic, for example polypropylene or polyethylene. The basic structure of the closure device 1 is similar to that in FIG FIG. 11 shown. However, since the lid member 4 is not made of aluminum, but rather of a plastic, rolling up of the lid member 4 on the container 2 is not possible. Instead, a counter-thread formed to the second thread 12 is provided directly on the cover element 4.

Die drehfeste Verbindung zwischen dem Deckelelement 4 und der Kammerwandung, insbesondere dem Kamer-Oberteil 6" kann zufolge Verklebung oder Verschweißung erreicht sein.The rotationally fixed connection between the cover element 4 and the chamber wall, in particular the camera upper part 6 ", can be achieved as a result of adhesive bonding or welding.

Auch kann gemäß der Darstellung in Figur 13 die Wandung des Kammerbereichs B materialeinheitlich und einstückig in die Wandung des Kammerbereichs A übergehen, wobei eine Kammerdecke des Bereichs A durch ein Folienelement 15, bspw. Aluminiumfolie, geschlossen ist. Bevorzugt handelt es sich hierbei um ein Folienelement 15 gemäß des zu Figur 7 beschriebenen.Also, as shown in FIG FIG. 13 the wall of the chamber area B material uniformly and in one piece in the wall of the chamber area A, wherein a chamber ceiling of the area A through a film element 15, for example. Aluminum foil, is closed. This is preferably a film element 15 according to the FIG. 7 described.
