Definitions
- the invention relates to a closure device according to the features of the preamble of claim 1.
- Closure devices of the aforementioned type are known in the prior art. These serve to close a container and at the same time provide a chamber for the separate storage of liquid or powdery media, for example tea essences or the like, so that these are not immediately filled when the container is filled with the contents of the container, i.e. for example water. come into contact and / or are mixed, but only at the moment when the closure device is removed from the container. This is usually the moment at which the contents of the container should be consumed.
- the publication WO 2007/129116 A1 relates, for example, to a closure device of the aforementioned type, which releases an additional liquid located in the chamber into the container when a container closed with it is opened.
- the closure device has a cover element, a chamber and an inner housing.
- the inner housing has a drain opening in which a closure means connected to the inner housing engages in a sealing manner.
- the closure means can be designed in the shape of a plug.
- the cover element and the inner housing can be connected to one another via a screw thread, with the cover element relative to the inner housing from a closed position, in which the closure means closes the drain opening of the chamber, into a drain position in which the closure means is at least partially withdrawn from the drain opening , is liftable to provide a communication path from the chamber into the main liquid space of the container.
- the medium stored in the chamber can escape into the container, whereby it is mixed with the medium in the container.
- closure edge interacts with the inner housing, at least in the closed position.
- the closure edge can be moved into a drain position, in particular due to an axial or rotational relative displacement of the closure edge to the inner housing.
- the chamber is locked to the inner housing above a lower tapering section which merges into opening means.
- a closure device in which a downwardly open gap between the chamber and a chamber end piece adjoining the chamber inwards is filled with an injected plastic seal.
- a closure device for a container in which the locking of the chamber with the inner housing is formed on a lower section of the inner housing near the edge, which is generally cylindrical.
- the medium must be applied to a stamp guided in the chamber by applying pressure to the end face area of a closure cap, which thereby cuts through an upper wall of the inner housing.
- the stamp ultimately pushes a lid that is locked in the chamber into the open position.
- the invention is initially concerned with the task of specifying a closure device which enables good handling, particularly if it is inexpensive to produce.
- the latching in the vertical direction is formed separately from a shoulder section of the inner housing which is formed on the bottom under the latching and is in an operative connection with the container opening.
- the proposed novel locking of the chamber with the inner housing results in an improvement, particularly with regard to the emptying of the chamber when the cover element is removed.
- the inner housing is in operative connection with the container opening of the container via the shoulder section, in particular in a frictional connection, further optionally, as is also preferred, forming a seal against the container opening.
- the chamber and inner housing as well as the assembly formed from the inner housing and chamber with the container can be assembled cheaply.
- the radial displacement of the locking mechanism inwards can be given by an amount which can correspond to approximately one sixth to one half, for example approximately one quarter, of the greatest width of the chamber transversely to the vertical direction of the closure device.
- the chamber can be composed of two parts, with a dividing plane that is perpendicular to a vertical central axis of the closure device, and the dividing plane can pass through an overlapping portion of the lower part of the chamber.
- the two parts can be welded together in the parting plane, the welding being achieved by a supplementary section which is connected to the two parts and is formed by injection molding.
- the two parts can also be welded together in the dividing plane, with the welding being covered on the outside by the upper part, with the upper part and the lower part of the chamber also being plug-connected.
- the two parts are welded together in the parting plane, the welding being achieved by a supplementary section which is connected to the two parts and formed by injection molding, that the supplementary section is designed in a ring shape and that in the edge region of the upper part there is a external in cross section, circumferential wedge surface is cut free to accommodate the supplementary section produced by overmolding the area or that the supplementary section has a radially outward cross-section and accordingly protrudes beyond the facing outer edge boundary of the upper and lower parts.
- the welding can be achieved by the supplementary section, which is connected to the two parts and is formed by injection molding.
- the supplementary section can, as is also preferred, consist of the same plastic material as the two parts forming the chamber or of a plastic material that enables welding to the two parts.
- the supplementary section can contain, for example, polybutylene terephthalate.
- the overmolding can advantageously also weld the two parts to the supplementary section, if necessary also against each other, in the course of the overmolding.
- the two parts of the chamber can also be welded together directly in the dividing plane.
- ultrasonic welding is preferred.
- the welding point can be covered from the outside by a section of the tank, in particular the upper part of the tank, so that the welding point (or the surrounding welding area) is hidden from view when looking at the closure device from the outside can.
- the upper part can extend like an apron beyond the welding point, preferably vertically downwards with respect to a usual position of use.
- the further preferred plug connection between the upper and lower parts can be used in particular for correct alignment of the parts relative to one another before and during a welding process. In addition, this can increase the stability in the welding area.
- the latching in the vertical direction is formed separately from a shoulder section of the inner housing formed on the bottom under the latching and the two parts of the chamber are welded together in the dividing plane, the welding being carried out by one with the
- the supplementary section, which is connected to both parts and is formed by overmolding, is reached or the welding is covered to the outside by the upper part of the tank, the upper part and the lower part of the tank also being plug-connected.
- a lower part of the two-part chamber can have structural means that would not be possible or would only be much more complex to produce if the chamber were manufactured in one piece in this form.
- the two parts of the chambers can be made from different materials.
- a plastic material at least partially different plastics or plastic mixtures can be used, but in addition, if necessary, different manufacturing processes, for example a plastic blowing process for a part of the chamber, for example a pot-like area of the chamber, and optionally a plastic injection molding process for producing the other part, which serves to fix the chamber as a whole to the inner housing and/or the cover element.
- the lower part of the chamber in particular can offer the closure means to interact with the inner housing.
- this also makes it possible to achieve cheaper, in particular significantly smaller, diameter dimensions in the area of the closure means of the chamber, which further has a positive effect on the frictional forces between the chamber and the inner housing on the one hand and the inner housing and a facing inner surface of a container neck on the other hand.
- the diameter ratio of the friction surfaces between the closure means and the inner housing as well as the inner housing and the inner wall facing the container neck can be influenced in a favorable manner due to the two-part production of the chamber with regard to the necessary maintenance of the frictional connection between the inner housing and the container neck in the course of a first opening rotational movement of the closure device.
- a favorable arrangement of the latches between the inner housing and the chamber and between the chamber and the cover element can be achieved on such different diameters that their latching projections and latching recesses run in a projection into a common plane transverse to the vertical axis without overlapping one another.
- the latching between the inner housing and the chamber can be formed on a free-standing cylinder section of the inner housing.
- a free-standing cylinder section can, for example, extend freely in the axial direction starting from a root area of the shoulder section into the circumferential wall of the inner housing, which is otherwise preferably pot-shaped on the bottom side, more preferably in such a way that an end of the cylinder section pointing vertically upwards in the usual position of use preferably neither receives support radially on the inside and radially on the outside.
- the above-described cylinder section can extend essentially radially inwards at a distance and at least approximately concentrically to a section of the shoulder section.
- the inner housing can at the same time have an internal thread for cooperation with an external thread of the container and a sealing lip which is spaced radially inwards from the internal thread.
- the sealing lip can, as is also preferred, run essentially concentrically to the area of the inner housing that has the internal thread. In the allocation position, the container neck, to which the closure device is held screw-connected, extends between the internal thread and the sealing lip.
- a free end of the sealing lip pointing in the axial direction of the closure device is preferably directed downward in the usual position of use, correspondingly preferably opposite to the orientation of the free end of the cylinder section described above.
- the sealing lip can be designed to overlap radially with the internal thread.
- the sealing lip is completely covered by the area of the inner housing that has the internal thread.
- the chamber can also be locked with the cover element and the inner housing on two mutually separate planes in the vertical direction, based on the state of use of the closure device, to form locking projections and locking recesses on the chamber, the cover element and the inner housing, the locking being relative to the inner housing the vertical central axis of the closure device is offset radially inwards relative to the locking with the cover element, the locking projections and the locking recesses of the planes running transversely to the vertical axis without overlapping one another when projected into a common plane.
- This locking of the chamber with the inner housing and the cover element is also an improvement, particularly with regard to the emptying of the chamber when the cover element is removed.
- the locking of the chamber with the inner housing is achieved in comparison to the locking of the chamber with the cover element with respect to the central axis at a significantly smaller transverse dimension, possibly diameter.
- the latching areas can be arranged with such different transverse dimensions to the central axis, or on such different diameters in a rotationally symmetrical design of the closure device, that in a projection of the latchings, in particular the latching projections and the latching recesses of the latchings, in a common plane running transversely to the central axis these do not overlap.
- the latches can be spaced differently from the central axis in relation to the central axis in such a way that a distance between the latching areas also results in a projection into a common plane.
- the locking between the chamber and the inner housing can be provided on a diameter circle, the diameter of which is 0.3 to 0.7 times. further, for example, can correspond to approximately 0.45 to 0.55 times the diameter of the latching between the chamber and the cover element.
- the relevant diameter line running in the plane preferably extends in the radial direction to the central axis viewed centrally between a radially inner or outer groove base of a locking recess and a radially outer or radially inner end of a locking projection which interacts with this locking recess.
- the locking projections can be formed on the lower part in the vertical direction during normal use of the closure device.
- This can be, for example, a hard plastic part, which can also be produced, for example, using a plastic injection molding process.
- both parts of the chamber can be made of a hard plastic. Both parts can also consist of the same hard plastic or be made essentially of the same hard plastic.
- PP polypropylene
- PE polyethylene
- PET polyethylene terephthalate
- Both parts can also contain polybutylene terephthalate (PBT).
- PBT polybutylene terephthalate
- the supplementary section can be designed annularly, preferably completely encompassing the parts with respect to the central axis of the closure device, whereby this annular enclosure can preferably only be present in an area assigned to the dividing plane.
- the supplementary section can be designed with reference to a vertical section in which the vertical central axis appears as a line, with a rear grip on the assigned sections of the two parts.
- a positive connection is provided between the supplementary section and one or the other part, preferably both parts of the chamber.
- the supplementary section can also be essentially triangular or trapezoidal in shape with respect to the vertical section.
- the supplementary section can be inserted like a wedge in the dividing plane between the mutually facing sections of the two parts and can preferably be welded to the two parts.
- dovetail-shaped rear grips can result in the fastening areas of the two parts of the chamber.
- the rear grips can, as is also preferred, be achieved in an advantageous manner by overmolding with the additional section material.
- the supplementary section can further clamp the two parts in the radial direction with respect to the central axis or vertical axis.
- the two parts can also be clamped in the vertical direction by appropriately designing a rear grip that acts in the vertical direction.
- the ranges or value ranges or multiple ranges specified above and below also include all intermediate values, in particular in 1/10 increments of the respective dimension, and if necessary also dimensionless.
- the statement 0.3 to 0.7 times also includes the disclosure of 0.31 to 0.7 times, 0.3 to 0.69 times, 0.31 to 0.69 times etc. This disclosure can, on the one hand, serve to delimit a specified range boundary from below and/or above, but alternatively or additionally to reveal one or more singular values from a respective specified range.
- a closure device 1 for a container 2 the closure device 1 essentially having a lid element 3, a chamber 4 and an inner housing 5, the chamber 4 being connected to the inner housing 5 via a (first) catch 6.
- the chamber 4 is preferably made of two parts 8, 9 composed, which parts 8, 9 are connected to one another in a dividing plane E running perpendicular to a vertical axis x.
- Figure 1 further shows an upper portion of the container 2, here for example in the form of a beverage bottle, at the container opening 10 of which the closure device 1 is arranged.
- the closure device 1 is located relative to the container 2 in a position that closes the container opening 10 in a fluid-tight manner, the closure device 1 being screwed to the container 2 in the usual manner, so that the container opening 10 is closed.
- the container 2 can be stored for a longer period of time without the contents being able to escape from the container 2.
- the closure device 1 is unscrewed from the container 2 in the usual way, so that the container opening 10 is finally completely exposed.
- the closure device 1 has a chamber 4 for the separate storage of, for example, liquid or powdery media, which is only released into the contents of the container 2 at the moment in which the closure device 1 is removed from the container 2.
- the chamber 4 can, as also shown and preferred, essentially consist of two parts 8, 9. Both parts 8, 9 can be made from the same material, in particular from the same hard plastic, for example from PE, PET or PP, whereby, according to a possible embodiment, both parts can also be made entirely of PBT or can have parts of PBT.
- the upper part 8 can be manufactured in a plastic injection-blowing process, alternatively in a plastic injection-molding process.
- the lower part 9 of the chamber 4 in this regard can, as is also preferred, be produced using the plastic injection molding process.
- the upper part 8 can also have a cup-shaped shape, with an overhead arrangement being provided with regard to the cup design.
- a connection to the lower part 9 is preferred along the edge region of the upper part 8 surrounding the pot opening pointing downwards.
- a permanent connection that cannot be detached operationally or by the user, in particular cannot be detached in a non-destructive manner, is preferred.
- a pressure-resistant connection is preferred in this regard, especially when receiving a medium in the chamber 4 with a pressure that is higher than the ambient pressure.
- the lower part 9 forms a preferably central drain connection 11.

Verschlussvorrichtungen der vorgenannten Art sind im Stand der Technik bekannt. Diese dienen dazu, einen Behälter zu verschließen und gleichzeitig eine Kammer zur separaten Speicherung von flüssigen oder pulverförmigen Medien, beispielsweise Tee-Essenzen oder dergleichen, bereitzustellen, so dass diese nicht unmittelbar beim Befüllen des Behälters mit dem Inhalt des Behälters, das heißt 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 der Inhalt des Behälters konsumiert werden soll.Closure devices of the aforementioned type are known in the prior art. These serve to close a container and at the same time provide a chamber for the separate storage of liquid or powdery media, for example tea essences or the like, so that these are not immediately filled when the container is filled with the contents of the container, i.e. for example water. come into contact and / or are mixed, but only at the moment when the closure device is removed from the container. This is usually the moment at which the contents of the container should be consumed.

Diese Aufgabe ist beim Gegenstand des Anspruches 1 gelöst, wobei darauf abgestellt ist, dass die Verrastung in der vertikalen Richtung gesondert von einem bodenseitig unter der Verrastung ausgebildeten, in einer Wirkverbindung mit der Behälteröffnung stehenden Schulterabschnitt des Innengehäuses ausgebildet ist.This object is achieved in the subject matter of
Durch die vorgeschlagene neuartige Verrastung der Kammer mit dem Innengehäuse ist eine Verbesserung insbesondere hinsichtlich der Entleerung der Kammer im Zuge einer Entfernung des Deckelelementes erreicht. Das Innengehäuse steht über den Schulterabschnitt in Wirkverbindung mit der Behälteröffnung des Behälters, insbesondere in einer Reibschlussverbindung, weiter gegebenenfalls, wie auch bevorzugt, unter Bildung einer Dichtung gegen die Behälteröffnung.The proposed novel locking of the chamber with the inner housing results in an improvement, particularly with regard to the emptying of the chamber when the cover element is removed. The inner housing is in operative connection with the container opening of the container via the shoulder section, in particular in a frictional connection, further optionally, as is also preferred, forming a seal against the container opening.
Es ergeben sich weiter zufolge der vorgeschlagenen Ausgestaltung eine günstige Montage von Kammer und Innengehäuse sowie darüber hinaus der aus Innengehäuse und Kammer gebildeten Baugruppe mit dem Behälter.According to the proposed design, the chamber and inner housing as well as the assembly formed from the inner housing and chamber with the container can be assembled cheaply.
Dabei kann die Radialversetzung der Verrastung nach innen um ein Maß gegeben sein, welches etwa einem Sechstel bis ein Halb, weiter beispiels-weise etwa ein Viertel der größten Breite der Kammer quer zur vertikalen Richtung der Verschlussvorrichtung entsprechen kann.The radial displacement of the locking mechanism inwards can be given by an amount which can correspond to approximately one sixth to one half, for example approximately one quarter, of the greatest width of the chamber transversely to the vertical direction of the closure device.
Die Kammer kann aus zwei Teilen zusammengesetzt sein, mit einer Teilungsebene, die senkrecht zu einer vertikalen Mittelachse der Verschlusseinrichtung verläuft, und die Teilungsebene kann einen Übergreifabschnitt des unteren Teils der Kammer durchsetzen.The chamber can be composed of two parts, with a dividing plane that is perpendicular to a vertical central axis of the closure device, and the dividing plane can pass through an overlapping portion of the lower part of the chamber.
Die beiden Teile können in der Teilungsebene miteinander verschweißt sein, wobei die Verschweißung durch einen mit den beiden Teilen in Verbindung stehenden, durch Umspritzen gebildeten Ergänzungsabschnitt erreicht ist.The two parts can be welded together in the parting plane, the welding being achieved by a supplementary section which is connected to the two parts and is formed by injection molding.
Auch können die beiden Teile in der Teilungsebene miteinander verschweißt sein, wobei die Verschweißung nach außen von dem oberen Teil überdeckt ist, wobei weiter das obere Teil und das untere Teil der Kammer im Übrigen steckverbunden sind.The two parts can also be welded together in the dividing plane, with the welding being covered on the outside by the upper part, with the upper part and the lower part of the chamber also being plug-connected.
Weiter kann vorgesehen sein, dass die beiden Teile in der Teilungsebene miteinander verschweißt sind, wobei die Verschweißung durch einen mit den beiden Teilen in Verbindung stehenden, durch Umspritzen gebildeten Ergänzungsabschnitt erreicht ist, dass der Ergänzungsabschnitt ringförmig gestaltet ist und dass im Randbereich des oberen Teils eine im Querschnitt äußere, umlaufende Keilfläche freigeschnitten ist, zur Aufnahme des durch Umspritzen des Bereiches hergestellten Ergänzungsabschnittes oder dass der Ergänzungsabschnitt im Querschnitt nach radial außen aufträgt und entsprechend über die zugewandte äußere Randbegrenzung des oberen und des unteren Teiles übersteht.Furthermore, it can be provided that the two parts are welded together in the parting plane, the welding being achieved by a supplementary section which is connected to the two parts and formed by injection molding, that the supplementary section is designed in a ring shape and that in the edge region of the upper part there is a external in cross section, circumferential wedge surface is cut free to accommodate the supplementary section produced by overmolding the area or that the supplementary section has a radially outward cross-section and accordingly protrudes beyond the facing outer edge boundary of the upper and lower parts.
Die Verschweißung kann durch den mit den beiden Teilen in Verbindung stehenden, durch Umspritzen gebildeten Ergänzungsabschnitt erreicht sein. Der Ergänzungsabschnitt kann dabei, wie auch bevorzugt, aus demselben Kunststoffmaterial bestehen wie die beiden, die Kammer bildenden Teile oder aus einem eine Verschweißung mit den beiden Teilen ermöglichenden Kunststoffmaterial. So kann in weiterer Ausgestaltung der Ergänzungsabschnitt beispielsweise Polybutylenterephthalat enthalten.The welding can be achieved by the supplementary section, which is connected to the two parts and is formed by injection molding. The supplementary section can, as is also preferred, consist of the same plastic material as the two parts forming the chamber or of a plastic material that enables welding to the two parts. In a further embodiment, the supplementary section can contain, for example, polybutylene terephthalate.
Durch das Umspritzen kann neben einer gegebenenfalls formschlüssigen Verbindung zwischen dem Ergänzungsabschnitt und den beiden Teilen der Kammer in vorteilhafter Weise auch eine Verschweißung der beiden Teile mit dem Ergänzungsabschnitt, gegebenenfalls auch gegeneinander, im Zuge der Umspritzung erreicht sein.In addition to an optionally positive connection between the supplementary section and the two parts of the chamber, the overmolding can advantageously also weld the two parts to the supplementary section, if necessary also against each other, in the course of the overmolding.
In weiterer Ausgestaltung können die beiden Teile der Kammer auch in der Teilungsebene unmittelbar miteinander verschweißt sein. Diesbezüglich wird eine Ultraschallverschweißung bevorzugt.In a further embodiment, the two parts of the chamber can also be welded together directly in the dividing plane. In this regard, ultrasonic welding is preferred.
Grundsätzlich kann die Schweißstelle, gegebenenfalls gebildet unter Nutzung eines Ergänzungsabschnittes, nach außen überdeckt sein durch einen Abschnitt des Tanks, insbesondere des oberen Teils des Tanks, sodass die Schweißstelle (bzw. der umlaufende Schweißbereich) mit Blick von außen auf die Verschlusseinrichtung der Sicht entzogen sein kann. Das obere Teil kann sich dabei schürzenartig über die Schweißstelle hinaus erstrecken, bevorzugt nach vertikal unten bezüglich einer üblichen Nutzungsstellung.In principle, the welding point, possibly formed using a supplementary section, can be covered from the outside by a section of the tank, in particular the upper part of the tank, so that the welding point (or the surrounding welding area) is hidden from view when looking at the closure device from the outside can. The upper part can extend like an apron beyond the welding point, preferably vertically downwards with respect to a usual position of use.
Die weiter bevorzugt gegebene Steckverbindung zwischen oberem und unterem Teil kann insbesondere für eine korrekte Ausrichtung der Teile relativ zueinander vor und im Zuge eines Schweißvorganges dienen. Darüber hinaus kann hierdurch eine Erhöhung der Stabilität im Schweißbereich erreicht sein.The further preferred plug connection between the upper and lower parts can be used in particular for correct alignment of the parts relative to one another before and during a welding process. In addition, this can increase the stability in the welding area.
Auch beim Gegenstand des Anspruches 2 kann vorgesehen sein, dass die Verrastung in der vertikalen Richtung gesondert ausgebildet ist von einem bodenseitig unter der Verrastung ausgebildeten Schulterabschnitt des Innengehäuses und die beiden Teile der Kammer in der Teilungsebene miteinander verschweißt sind, wobei die Verschweißung durch einen mit den beiden Teilen in Verbindung stehenden, durch Umspritzen gebildeten Ergänzungsabschnitt erreicht ist oder wobei die Verschweißung nach außen von dem oberen Teil des Tanks überdeckt ist, wobei weiter das obere Teil und das untere Teil des Tanks im Übrigen steckverbunden sind.In the subject matter of
Die Zusammensetzung der Kammer aus zwei Teilen erweist sich sowohl herstellungs- als auch handhabungstechnisch von Vorteil. So kann zufolge dieser Ausgestaltung ein unteres Teil der zweiteiligen Kammer über konstruktive Mittel verfügen, die bei einer einteiligen Herstellung der Kammer in dieser Form nicht oder nur wesentlich aufwendiger herzustellen wären. So können die beiden Teile der Kammern beispielsweise aus unterschiedlichen Materialien hergestellt sein. Auch bei der Herstellung der Kammer bevorzugt aus einem Kunststoffwerkstoff können so zumindest partiell unterschiedliche Kunststoffe oder Kunststoffmischungen zur Verwendung kommen, darüber hinaus aber auch gegebenenfalls unterschiedliche Herstellungsverfahren, so beispielsweise ein Kunststoff-Blasverfahren für ein Teil der Kammer, beispielsweise einen topfartigen Bereich der Kammer, und gegebenenfalls ein Kunststoff-Spritzverfahren zur Herstellung des anderen Teils, welches der Festlegung der Kammer insgesamt an dem Innengehäuse und/oder dem Deckelelement dient.The composition of the chamber in two parts proves to be advantageous in terms of both manufacturing and handling. According to this embodiment, a lower part of the two-part chamber can have structural means that would not be possible or would only be much more complex to produce if the chamber were manufactured in one piece in this form. For example, the two parts of the chambers can be made from different materials. When producing the chamber, preferably from a plastic material, at least partially different plastics or plastic mixtures can be used, but in addition, if necessary, different manufacturing processes, for example a plastic blowing process for a part of the chamber, for example a pot-like area of the chamber, and optionally a plastic injection molding process for producing the other part, which serves to fix the chamber as a whole to the inner housing and/or the cover element.
Dabei kann weiter das insbesondere untere Teil der Kammer das Verschlussmittel anbieten, zur Zusammenwirkung mit dem Innengehäuse.The lower part of the chamber in particular can offer the closure means to interact with the inner housing.
Auch können hierdurch im Vergleich zu einer einteiligen, bevorzugt im Kunststoff-Blasverfahren hergestellten Kammer günstigere, so insbesondere wesentlich geringere Durchmessermaße im Bereich des Verschlussmittels der Kammer erreicht werden, was sich weiter günstig auf die Reibungskräfte zwischen der Kammer und dem Innengehäuse einerseits und dem Innengehäuse und einer zugewandten Innenfläche eines Behälterhalses andererseits auswirkt. Das Durchmesserverhältnis der Reibflächen zwischen Verschlussmittel und Innengehäuse sowie Innengehäuse und zugewandter Innenwandung des Behälterhalses kann zufolge der zweiteiligen Herstellung der Kammer im Hinblick auf die nötige Erhaltung des Reibschlusses zwischen Innengehäuse und Behälterhals im Zuge einer ersten Öffnungsdrehbewegung der Verschlussvorrichtung in günstiger Weise beeinflusst werden.In comparison to a one-piece chamber, preferably produced using the plastic blow molding process, this also makes it possible to achieve cheaper, in particular significantly smaller, diameter dimensions in the area of the closure means of the chamber, which further has a positive effect on the frictional forces between the chamber and the inner housing on the one hand and the inner housing and a facing inner surface of a container neck on the other hand. The diameter ratio of the friction surfaces between the closure means and the inner housing as well as the inner housing and the inner wall facing the container neck can be influenced in a favorable manner due to the two-part production of the chamber with regard to the necessary maintenance of the frictional connection between the inner housing and the container neck in the course of a first opening rotational movement of the closure device.
Auch kann zufolge der zweiteiligen Ausgestaltung der Kammer eine günstige Anordnung der Verrastungen zwischen Innengehäuse und Kammer sowie zwischen Kammer und Deckelelement auf derart unterschiedlichen Durchmessern erreicht werden, dass deren Rastvorsprünge und Rastausnehmungen in einer Projektion in eine gemeinsame Ebene quer zur Vertikalachse ohne Überdeckung zueinander verlaufen.Due to the two-part design of the chamber, a favorable arrangement of the latches between the inner housing and the chamber and between the chamber and the cover element can be achieved on such different diameters that their latching projections and latching recesses run in a projection into a common plane transverse to the vertical axis without overlapping one another.
Die Verrastung zwischen dem Innengehäuse und der Kammer kann gemäß einer weiter bevorzugten Ausgestaltung an einem freistehenden Zylinderabschnitt des Innengehäuses ausgebildet sein. Ein solcher freistehender Zylinderabschnitt kann sich beispielsweise ausgehend von einem Wurzelbereich des Schulterabschnittes in die umlaufende Wandung des im Übrigen bodenseitig topfförmig bevorzugt gestalteten Innengehäuses frei in Achsrichtung hinaus erstrecken, weiter bevorzugt derart, dass ein in der üblichen Nutzungsstellung nach vertikal oben weisendes Ende des Zylinderabschnitts bevorzugt weder radial innen noch radial außen eine Abstützung erfährt.According to a further preferred embodiment, the latching between the inner housing and the chamber can be formed on a free-standing cylinder section of the inner housing. Such a free-standing cylinder section can, for example, extend freely in the axial direction starting from a root area of the shoulder section into the circumferential wall of the inner housing, which is otherwise preferably pot-shaped on the bottom side, more preferably in such a way that an end of the cylinder section pointing vertically upwards in the usual position of use preferably neither receives support radially on the inside and radially on the outside.
Darüber hinaus kann der vorbeschriebene Zylinderabschnitt sich gemäß einer möglichen Ausgestaltung im Wesentlichen radial innen mit Abstand und zumindest annähernd konzentrisch zu einem Abschnitt des Schulterabschnittes erstrecken.In addition, according to a possible embodiment, the above-described cylinder section can extend essentially radially inwards at a distance and at least approximately concentrically to a section of the shoulder section.
In weiterer Ausgestaltung kann das Innengehäuse zugleich ein Innengewinde zur Zusammenwirkung mit einem Außengewinde des Behälters aufweisen sowie eine Dichtlippe, die nach radial innen von dem Innengewinde beabstandet ist. Die Dichtlippe kann, wie auch bevorzugt, im Wesentlichen konzentrisch zu dem das Innengewinde aufweisenden Bereich des Innengehäuses verlaufen. Zwischen dem Innengewinde und der Dichtlippe erstreckt sich in Zuordnungsstellung der Behälterhals, an welchem die Verschlussvorrichtung schraubverbunden gehalten ist. Ein in Achsrichtung der Verschlussvorrichtung weisendes freies Ende der Dichtlippe ist in üblicher Nutzungsstellung bevorzugt nach unten gerichtet, entsprechend bevorzugt entgegengerichtet zu der Ausrichtung des freien Endes des vorbeschriebenen Zylinderabschnitts.In a further embodiment, the inner housing can at the same time have an internal thread for cooperation with an external thread of the container and a sealing lip which is spaced radially inwards from the internal thread. The sealing lip can, as is also preferred, run essentially concentrically to the area of the inner housing that has the internal thread. In the allocation position, the container neck, to which the closure device is held screw-connected, extends between the internal thread and the sealing lip. A free end of the sealing lip pointing in the axial direction of the closure device is preferably directed downward in the usual position of use, correspondingly preferably opposite to the orientation of the free end of the cylinder section described above.
Die Dichtlippe kann in radialer Überdeckung zu dem Innengewinde ausgebildet sein. Diesbezüglich ist eine vollständige Überdeckung der Dichtlippe durch den das Innengewinde aufweisenden Bereich des Innengehäuses gegeben.The sealing lip can be designed to overlap radially with the internal thread. In this regard, the sealing lip is completely covered by the area of the inner housing that has the internal thread.
Auch kann die Kammer mit dem Deckelelement und dem Innengehäuse an zwei zueinander, bezogen auf den Nutzungszustand der Verschlussvorrichtung in vertikaler Richtung gesonderten Ebenen unter Ausbildung von Rastvorsprüngen und Rastausnehmungen an der Kammer, dem Deckelelement und dem Innengehäuse verrastet sein, wobei die Verrastung mit dem Innengehäuse bezüglich der vertikalen Mittelachse der Verschlussvorrichtung nach radial innen versetzt ist gegenüber der Verrastung mit dem Deckelelement, wobei die Rastvorsprünge und die Rastausnehmungen der Ebenen bei einer Projektion in eine gemeinsame Ebene quer zur Vertikalachse ohne Überdeckung zueinander verlaufen.The chamber can also be locked with the cover element and the inner housing on two mutually separate planes in the vertical direction, based on the state of use of the closure device, to form locking projections and locking recesses on the chamber, the cover element and the inner housing, the locking being relative to the inner housing the vertical central axis of the closure device is offset radially inwards relative to the locking with the cover element, the locking projections and the locking recesses of the planes running transversely to the vertical axis without overlapping one another when projected into a common plane.
Auch diese Verrastung der Kammer mit dem Innengehäuse und dem Deckelelement ist eine Verbesserung insbesondere hinsichtlich der Entleerung der Kammer im Zuge einer Entfernung des Deckelelementes erreicht. Die Verrastung der Kammer mit dem Innengehäuse ist dabei im Vergleich zu der Verrastung der Kammer mit dem Deckelelement mit Bezug auf die Mittelachse auf einem wesentlich geringeren Quermaß, gegebenenfalls Durchmesser, erreicht.This locking of the chamber with the inner housing and the cover element is also an improvement, particularly with regard to the emptying of the chamber when the cover element is removed. The locking of the chamber with the inner housing is achieved in comparison to the locking of the chamber with the cover element with respect to the central axis at a significantly smaller transverse dimension, possibly diameter.
Dabei können die Verrastungsbereiche mit solchen unterschiedlichen Querabmessungen zu der Mittelachse, beziehungsweise auf derart unterschiedlichen Durchmessern bei einer rotationssymetrischen Ausgestaltung der Verschlussvorrichtung, angeordnet sein, dass in einer Projektion der Verrastungen, insbesondere der Rastvorsprünge und der Rastausnehmungen der Verrastungen in eine gemeinsame quer zur Mittelachse verlaufenden Ebene diese nicht in Überdeckung liegen.The latching areas can be arranged with such different transverse dimensions to the central axis, or on such different diameters in a rotationally symmetrical design of the closure device, that in a projection of the latchings, in particular the latching projections and the latching recesses of the latchings, in a common plane running transversely to the central axis these do not overlap.
Dabei können weiter die Verrastungen mit Bezug zu der Mittelachse derart unterschiedlich zu der Mittelachse beabstandet sein, dass sich auch in einer Projektion in eine gemeinsame Ebene ein Abstand zwischen den Verrastungsbereichen ergibt.In this case, the latches can be spaced differently from the central axis in relation to the central axis in such a way that a distance between the latching areas also results in a projection into a common plane.
Gemäß einer möglichen Ausgestaltung kann beispielsweise bei einer rotationssymetrischen Ausgestaltung der Verschlussvorrichtung, bei welcher die Mittelachse zugleich eine Rotationsachse bildet, die Verrastung zwischen der Kammer und dem Innengehäuse auf einen Durchmesserkreis vorgesehen sein, dessen Durchmessermaß dem 0,3- bis 0,7-Fachen, weiter beispielsweise etwa dem 0,45- bis 0,55-Fachen des Durchmessermaßes der Verrastung zwischen der Kammer und dem Deckelelement entsprechen kann.According to a possible embodiment, for example, in a rotationally symmetrical configuration of the closure device, in which the central axis also forms an axis of rotation, the locking between the chamber and the inner housing can be provided on a diameter circle, the diameter of which is 0.3 to 0.7 times. further, for example, can correspond to approximately 0.45 to 0.55 times the diameter of the latching between the chamber and the cover element.
Die hierbei relevante, in der Ebene verlaufende Durchmesserlinie erstreckt sich dabei bevorzugt in radialer Richtung zu der Mittelachse betrachtet mittig zwischen einem radial inneren oder äußeren Nutgrund einer Rastausnehmung und einem radial äußeren beziehungsweise radial inneren Ende eines mit dieser Rastausnehmung zusammenwirkenden Rastvorsprungs.The relevant diameter line running in the plane preferably extends in the radial direction to the central axis viewed centrally between a radially inner or outer groove base of a locking recess and a radially outer or radially inner end of a locking projection which interacts with this locking recess.
Durch die Anordnung und Ausbildung der Verrastungen auf bevorzugt deutlich unterschiedlichen Durchmessern ist zudem eine günstige Herstellbarkeit, insbesondere eine günstige Verrastung im Zuge der Montage der Verschlussvorrichtung erreichbar.By arranging and designing the latches on preferably significantly different diameters, it is also possible to achieve favorable manufacturability, in particular favorable latching during the assembly of the closure device.
Gemäß einer weiteren möglichen Ausgestaltung können an dem in Vertikalrichtung bei üblicher Nutzung der Verschlussvorrichtung unteren Teil die Rastvorsprünge ausgebildet sein. Dabei kann es sich beispielsweise um ein Hartkunststoffteil handeln, welches weiter beispielsweise im Kunststoff-Spritzverfahren hergestellt sein kann.According to a further possible embodiment, the locking projections can be formed on the lower part in the vertical direction during normal use of the closure device. This can be, for example, a hard plastic part, which can also be produced, for example, using a plastic injection molding process.
Darüber hinaus können beide Teile der Kammer aus einem Hartkunststoff bestehen. Auch können beide Teile aus demselben Hartkunststoff bestehen beziehungsweise im Wesentlichen aus demselben Hartkunststoff hergestellt sein. So kann diesbezüglich als Hartkunststoffmaterial Polypropylen (PP), Polyethylen (PE) oder auch Polyethylenterephthalat (PET) Verwendung finden.In addition, both parts of the chamber can be made of a hard plastic. Both parts can also consist of the same hard plastic or be made essentially of the same hard plastic. In this regard, polypropylene (PP), polyethylene (PE) or polyethylene terephthalate (PET) can be used as hard plastic materials.
Auch können beide Teile Polybutylenterephthalat (PBT) enthalten.Both parts can also contain polybutylene terephthalate (PBT).
Der Ergänzungsabschnitt kann ringförmig gestaltet sein, dabei die Teile mit Bezug auf die Mittelachse der Verschlussvorrichtung bevorzugt vollumfänglich umfassend, wobei diese ringförmige Umfassung bevorzugt allein in einem der Teilungsebene zugeordneten Bereich gegeben sein kann.The supplementary section can be designed annularly, preferably completely encompassing the parts with respect to the central axis of the closure device, whereby this annular enclosure can preferably only be present in an area assigned to the dividing plane.
In einer möglichen Ausgestaltung kann der Ergänzungsabschnitt mit Bezug auf einen Vertikalschnitt, in welchem sich die vertikale Mittelachse als Linie darstellt, mit einem Hintergriff zu den zugeordneten Abschnitten der beiden Teile ausgebildet sein. Hierdurch ist gegebenenfalls zusätzlich zu einer Verschweißung eine formschlüssige Verbindung zwischen dem Ergänzungsabschnitt und dem einen oder anderen Teil, bevorzugt zu beiden Teilen der Kammer, gegeben.In a possible embodiment, the supplementary section can be designed with reference to a vertical section in which the vertical central axis appears as a line, with a rear grip on the assigned sections of the two parts. In this way, in addition to welding, a positive connection is provided between the supplementary section and one or the other part, preferably both parts of the chamber.
Insbesondere bei einer befüllten Verschlussvorrichtung, bei welcher das bevorratete Medium bevorzugt mit einem Überdruck in der Kammer aufgenommen ist, erweist sich eine solche gegebenenfalls zusätzliche formschlüssige Verbindung als vorteilhaft.Particularly in the case of a filled closure device, in which the stored medium is preferably accommodated in the chamber with an excess pressure, such an optionally additional positive connection proves to be advantageous.
Darüber hinaus kann der Ergänzungsabschnitt auch bezogen auf den Vertikalschnitt im Wesentlichen dreieckförmig oder trapezförmig gebildet sein. Bei einer dreieckförmigen Ausgestaltung kann der Ergänzungsabschnitt keilartig in der Teilungsebene zwischen den aufeinander zuweisenden Abschnitten der beiden Teile eingesetzt und bevorzugt mit den beiden Teilen verschweißt sein.In addition, the supplementary section can also be essentially triangular or trapezoidal in shape with respect to the vertical section. In the case of a triangular configuration, the supplementary section can be inserted like a wedge in the dividing plane between the mutually facing sections of the two parts and can preferably be welded to the two parts.
Bei einer beispielhaften trapezförmigen Gestaltung des Ergänzungsabschnittes können sich beispielsweise schwalbenschwanzförmige Hintergriffe zu den Befestigungsbereichen der beiden Teile der Kammer ergeben.With an exemplary trapezoidal design of the supplementary section, dovetail-shaped rear grips can result in the fastening areas of the two parts of the chamber.
Die Hintergriffe können, wie auch bevorzugt, in vorteilhafter Weise durch Umspritzen mit dem Ergänzungsabschnittmaterial erreicht werden.The rear grips can, as is also preferred, be achieved in an advantageous manner by overmolding with the additional section material.
So kann weiter der Ergänzungsabschnitt die beiden Teile mit Bezug auf die Mittelachse oder Vertikalachse in Radialrichtung verklammern. Darüber hinaus kann alternativ oder auch kombinativ zu einer solchen radialen Verklammerung auch eine Verklammerung der beiden Teile in Vertikalrichtung erreicht sein, durch entsprechende Ausbildung eines in Vertikalrichtung wirkenden Hintergriffs.The supplementary section can further clamp the two parts in the radial direction with respect to the central axis or vertical axis. In addition, as an alternative or in combination with such a radial clamping The two parts can also be clamped in the vertical direction by appropriately designing a rear grip that acts in the vertical direction.
Die vor- und nachstehend angegebenen Bereiche beziehungsweise Wertebereiche oder Mehrfachbereiche schließen hinsichtlich der Offenbarung auch sämtliche Zwischenwerte ein, insbesondere in 1/10-Schritten der jeweiligen Dimension, gegebenenfalls also auch dimensionslos. Beispielsweise beinhaltet die Angabe 0,3- bis 0,7-Fach auch die Offenbarung von 0,31- bis 0,7-Fach, 0,3-bis 0,69-Fach, 0,31- bis 0,69-Fach etc. Diese Offenbarung kann einerseits zur Eingrenzung einer genannten Bereichsgrenze von unten und/oder oben, alternativ oder ergänzend aber zur Offenbarung eines oder mehrerer singulärer Werte aus einem jeweilig angegebenen Bereich dienen.With regard to the disclosure, the ranges or value ranges or multiple ranges specified above and below also include all intermediate values, in particular in 1/10 increments of the respective dimension, and if necessary also dimensionless. For example, the statement 0.3 to 0.7 times also includes the disclosure of 0.31 to 0.7 times, 0.3 to 0.69 times, 0.31 to 0.69 times etc. This disclosure can, on the one hand, serve to delimit a specified range boundary from below and/or above, but alternatively or additionally to reveal one or more singular values from a respective specified range.

Dargestellt und beschrieben ist, zunächst mit Bezug zu
Die Verschlussvorrichtung 1 befindet sich relativ zu dem Behälter 2 in einer die Behälteröffnung 10 fluiddicht verschließenden Stellung, wobei die Verschlussvorrichtung 1 in üblicher Weise an den Behälter 2 angeschraubt ist, so dass die Behälteröffnung 10 verschlossen ist.The
In diesem Zustand kann der Behälter 2 über längere Zeit gelagert werden, ohne dass der Inhalt aus dem Behälter 2 austreten kann. Zum Öffnen des Behälters 2 wird die Verschlussvorrichtung 1 in üblicher Weise von dem Behälter 2 abgeschraubt, so dass die Behälteröffnung 10 schließlich vollständig freiliegt.In this state, the
Die Verschlussvorrichtung 1 weist eine Kammer 4 zur separaten Speicherung von beispielsweise flüssigen oder pulverförmigen Medien, die erst in dem Moment, in dem die Verschlussvorrichtung 1 von dem Behälter 2 entfernt wird zu dem Inhalt des Behälters 2 abgegeben wird.The
Die Kammer 4 kann, wie auch dargestellt und bevorzugt, im Wesentlichen aus zwei Teilen 8, 9 bestehen. Hierbei können beide Teile 8, 9 aus demselben Werkstoff, insbesondere aus demselben Hartkunststoff hergestellt sein, so beispielsweise aus PE, PET oder PP, wobei weiter gemäß einer möglichen Ausgestaltung beide Teile auch vollständig aus PBT gebildet sein können beziehungsweise Teile von PBT aufweisen können.The
Dabei kann weiter das mit Bezug auf die übliche Nutzungsstellung der Verschlussvorrichtung 1, bei welcher sich die Achse x im Wesentlichen vertikal erstreckt, obere Teil 8 in einem Kunststoff-Spritzblasverfahren hergestellt sein, alternativ in einem Kunststoff-Spritzverfahren.In this case, with reference to the usual position of use of the
Das diesbezüglich untere Teil 9 der Kammer 4 kann, wie auch bevorzugt, im Kunststoff-Spritzverfahren hergestellt sein.The
Dabei kann weiter das obere Teil 8 eine topfförmige Gestalt aufweisen, wobei bezüglich der Topfgestaltung eine Überkopfanordnung vorgesehen ist. Entlang des die nach unten weisende Topföffnung umgebenden Randbereiches des oberen Teiles 8 ist eine Verbindung mit dem unteren Teil 9 bevorzugt.The
In diesem Zusammenhang ist eine dauerhafte, betrieblich und auch durch den Anwender nicht lösbare, insbesondere nicht zerstörungsfrei lösbare Verbindung bevorzugt. Weiter ist diesbezüglich eine auch druckresistente Verbindung bevorzugt, insbesondere bei Aufnahme eines Mediums in der Kammer 4 mit einem gegenüber dem Umgebungsdruck erhöhten Druck.In this context, a permanent connection that cannot be detached operationally or by the user, in particular cannot be detached in a non-destructive manner, is preferred. Furthermore, a pressure-resistant connection is preferred in this regard, especially when receiving a medium in the
Das untere Teil 9 formt einen bevorzugt zentralen Ablassstutzen 11.The
Das Innengehäuse 5 kann gemäß den Darstellungen topfartiger Gestalt sein, mit einer umlaufenden Topfwandung und einem Kragen 12 zur Abstützung auf dem die Behälteröffnung 10 umgebenden Behälterrand.The
Unterseitig des Innengehäuse-Kragens 12 kann umlaufend eine Dichtlippe 13 angeformt sein. Diese wirkt in der Zuordnungsstellung gemäß
Bodenseitig ist ein Kammerboden 14 ausgebildet, welcher umlaufend über seinen gesamten Umfang übergeht in eine Rinne 15. Diese Rinne 15 ist mit Bezug auf die Schnittdarstellung in
Die radial innere Seitenwand 16 geht fußseitig über in den Rinnenboden 18 und kopfseitig in den axial zu dem Rinnenboden 18 beabstandeten Kammerboden 14 über. Der Kammerboden 14 kann, wie auch dargestellt, im Wesentlichen quergerichtet verlaufen zu der Vertikalachse x, weiter gegebenenfalls in Parallelausrichtung zu dem Rinnenboden 18.The radially
Die radial äußere Rinnenseitenwand 17 kann im Wesentlichen die Gehäusewandung des Innengehäuses 5 ausformen.The radially outer
Insbesondere die Oberfläche des Rinnenbodens 18, darüber hinaus bevorzugt aber auch die in den Rinnenraum weisende Fläche der radial inneren Rinnenseitenwand 16 und gegebenenfalls auch, wie dargestellt, die der Kammer 4 zugewandte Oberfläche des Kammerbodens 14 können, wie auch bevorzugt, überdeckt sein von einer Weichkunststofflage 19. Diese kann, wie auch bevorzugt, im Zwei-Komponenten-Spritzverfahren zusammen mit dem Innengehäuse 5 hergestellt sein. Alternativ ist die Weichkunststofflage 19 gesondert als topfartiges Teil herstellbar und beispielsweise innenseitig des Innengehäuses 5 rastfestlegbar.In particular, the surface of the gutter bottom 18, but also preferably the surface of the radially inner

Zur Herstellung der Weichkunststofflage 19 kann beispielsweise ein thermoplastisches Elastomer (TPE) genutzt sein.For example, a thermoplastic elastomer (TPE) can be used to produce the
Wie weiter insbesondere aus der Darstellung in
Bodenseitig der Rinne 15 ist weiter eine, sowohl den Rinnenboden 18 als auch den den Rinnenboden 18 überdeckenden Abschnitt der Weichkunststofflage 19 durchsetzende Ablassöffnung 21 vorgesehen. Diese kann, wie auch bevorzugt, in einer Ebene quer zur Vertikalachse x betrachtet, eine kreisringförmig umlaufende Öffnungsrandkante aufweisen, gegebenenfalls mit einem Durchmesser, der der radialen Breite der Rinne 15 zwischen der radial inneren Rinnenseitenwand 16 und der radial äußeren Rinnenseitenwand 17 entsprechen kann. Weiter bevorzugt kann die Rinne 15 nur eine solche Ablassöffnung 21 aufweisen.On the bottom side of the
Die Weichkunststofflage 19 bildet ein Dichtelement 22, zur Zusammenwirkung mit einem Verschlussmittel V, das in der dargestellten Ausführungsform im Wesentlichen stopfenartig gebildet ist, insbesondere ausgeformt durch die Wandung des Ablassstutzens 11.The
Der Ablassstutzen 11 erstreckt sich im Wesentlichen in Art eines Kreiszylinders, wobei das im Nutzungszustand in üblicher Weise nach unten weisende freie, entsprechend ringförmig umlaufende Ende, das Verschlussmittel V bildend, in die Rinne 15 des Innengehäuses 5 eintaucht.The
Das Verschlussmittel V, hier entsprechend der ringförmige Endbereich des Ablassstutzens 11, ist permanent in dem Dichtelement 22, hier der Rinne 15, einsitzend, wird entsprechend bevorzugt nicht relativ zu diesem in Richtung der Vertikalachse x verlagert. Es erfolgt bevorzugt allein eine Verlagerung des Verschlussmittels V relativ zu dem Dichtelement 22, insbesondere zu der Weichkunststofflage 19, in Umfangsrichtung, dies beispielsweise anschlagbegrenzt über einen Winkel von weiter beispielsweise etwa 180 Grad.The closure means V, here corresponding to the annular end region of the
Das Verschlussmittel V kann hierbei eine Ausgabeausformung 23 aufweisen, beispielsweise in Form einer nach radial innen in Richtung auf die radial innere Rinnenseitenwand 16 und nach axial unten in Richtung auf die Ablassöffnung 21 randoffenen Nut. Diese kann in der Verschlussstellung gemäß den Darstellungen in den
Auch diese Ausgabeausnehmung 24 kann in Form einer Nut gebildet sein, insbesondere in Form einer in Achsrichtung verlaufenden Nut. Weiter kann gemäß den dargestellten Ausführungsbeispielen diese Ausgabeausnehmung 24 axial beabstandet zu der Ablassöffnung 21 im Übergang von der inneren Rinnenseitenwand 16 in den Kammerboden 14 vorgesehen sein.This
Entsprechend ergibt sich im Bereich der Ausgabeausnehmung 24 eine partielle Radialerweiterung der Rinne 15.Accordingly, there is a partial radial expansion of the

Die Relativverdrehung der mit dem Verschlussmittel V versehenen Kammer 4 zu dem Innengehäuse 5 ist bevorzugt anschlagbegrenzt. Hierzu kann beispielsweise an der Kammer 4, bspw. radial außen an dem Ablassstutzen 11, ein Radialvorsprung 25 angeformt sein, der mit entsprechend positionierten Anschlägen 26 beziehungsweise 27 des Innengehäuses 5 zusammenwirken kann (vergleiche

Darüber hinaus kann das untere Teil 9 in axialer Richtung betrachtet zwischen dem das Verschlussmittel V im Wesentlichen bildenden Endbereich des Ablassstutzens 11 und dem den Radialvorsprung 25 aufweisenden Bereich einen mit Bezug zur Vertikalachse x bevorzugt ringförmig umlaufenden Rastvorsprung 30 aufweisen. Dieser Rastvorsprung 30 greift zur Bildung der (ersten) Verrastung 6 in eine wandungsinnenseitig der umlaufenden Innengehäuse-Wandung ausgeformte rillenartige Rastausnehmung 31.In addition, the
Neben der so gebildeten (ersten) Verrastung 6 kann hierdurch weiter eine Drehlagerung für die Kammer 4, insbesondere dessen unteren Teils 9 an dem Innengehäuse 5 gegeben sein.In addition to the (first) latching 6 formed in this way, a rotary bearing for the

Ein ebenfalls quer zur vertikalen Richtung M betrachtetes Erstreckungsmaß im Bereich der Verrastung 6 kann etwa dem 0,4- bis 0,8-Fachen, weiter etwa einem 0,5- bis 0,6-Fachen der vorbeschriebenen Breite k der Kammer 4 entsprechen.Compared to a largest width k of the

Dieser Schulterabschnitt 40 schließt außenseitig im Bereich des oberen Endes der topfartig umlaufenden Rinnenseitenwand 17 an und verläuft in einem Aufwärtsbogen unter etwa paralleler Beabstandung zu der Dichtlippe 13 bis in den im Wesentlichen quer zur Vertikalachse x verlaufenden Kragen 12.This
Über den Wurzelbereich des Schulterabschnitts 12 an der Rinnenseitenwand 17 nach vertikal oben hinaus, schließt sich ein freistehender Zylinderabschnitt 42 an, an dessen nach radial innen weisender Wandung die Rastausnehmung 31, beispielsweise in Form einer umlaufenden Nut, ausgebildet ist.Beyond the root area of the

Es kann sich entsprechend bei einer Verdrehung der Kammer 4 relativ zu dem Innengehäuse 5 zur Freigabe der Ablassöffnung 21 eine umlaufende Reibfläche zwischen dem unteren Teil 9 der Kammer 4 und dem Innengehäuse 5 ergeben, so insbesondere im Zusammenwirkungsbereich von Rastvorsprung 30 und Rastausnehmung 31, darüber hinaus gegebenenfalls aber auch zwischen dem das Verschlussmittel V bildenden freien Ende des Ablassstutzens 11 und insbesondere der radial äußeren Rinnenseitenwänden 17. Diese Reibflächen erstrecken sich zumindest annähernd im Bereich gleicher Durchmessermaße a, welches Durchmessermaß a etwa dem 0,4- bis 0,6-Fachen des freien Innendurchmessers b im Bereich der Behälteröffnung 10 entsprechen kann.Accordingly, when the

Zufolge der anhand des ersten Ausführungsbeispiels beschriebenen Verrastung ist eine günstige Montage erreichbar. Diese ist schematisch in Figur 8 dargestellt. Die zu der Kammer 4 zusammengefügten Teile 8 und 9 können mit Bezug auf eine übliche Nutzungsstellung von oben in das Deckelelement 3 eingesteckt und mit diesem verrastet werden (siehe Pfeil c), während das Innengehäuse 5 in Gegenrichtung von unten in das Deckelelement 3 eingeführt und mit der Kammer 4 im Bereich der ersten Verrastung 6 verbunden wird (siehe Pfeil d).As a result of the locking described using the first exemplary embodiment, favorable assembly can be achieved. This is shown schematically in Figure 8. The
