Description

Die Erfindung betrifft eine gattungsgemässe Kapsel nach dem Oberbegriff des Hauptanspruchs, nämlich eine Kapsel mit einem Innenraum, mit einem Boden und mit einem dazu entgegengesetzt angeordneten, den ein Getränkepulver für die Zubereitung einer Portion eines heissen Brühgetränks wie Kaffee, Tee oder Boullion bei der Durchleitung von Wasserdampf aufweisenden Innenraum dicht verschliessenden Deckel. Dabei kann die im Querschnitt kreisförmige Kapsel mit einer konusförmigen Wandung zwischen dem Boden und dem Deckel versehen sein, wobei der eben ausgebildete Boden über einen Kegelstumpf in die konusförmige Wandung übergeht.The invention relates to a generic capsule according to the preamble of the main claim, namely a capsule with an interior, with a bottom and with an oppositely arranged one, which is a beverage powder for the preparation of a portion of a hot brewed beverage such as coffee, tea or boullion when passing through Water-tight interior sealing lid. The capsule, which is circular in cross section, can be provided with a conical wall between the base and the cover, the base which has just been formed merging into the conical wall via a truncated cone.

Eine solche Kapsel ist bekannt und ihr Einsatz erfreut sich allgemein grosser Beliebtheit (wie zum Beispiel bei WO 2015/124534 A1 oder EP 20 29 457 B1 ). Dabei wird die Kapsel in eine Brühvorrichtung eingesetzt, die dabei den Deckel perforiert und den Boden mittels Dampflanzen öffnet, über die Wasserdampf durch das Getränkepulver unter Erzeugung des heissen Brühgetränks gepresst wird, das durch den perforierten Deckel unter Zurückhaltung des Getränkepulvers aus der Kapsel herausfliesst und in ein Gefäss z.B. eine Tasse geleitet wird.Such a capsule is known and its use is generally very popular (such as in WO 2015/124534 A1 or EP 20 29 457 B1 ). The capsule is inserted into a brewing device, which perforates the lid and opens the bottom by means of steam lances, via which water vapor is pressed through the beverage powder to produce the hot brewing beverage, which flows out of the capsule and retains the beverage powder, holding it in a vessel, for example a cup, is directed.

Dabei wird der Wasserdampf in einer Richtung von dem Boden zu dem Deckel durch das Getränkepulver bewegt. Dazu ist einerseits ein ausreichend hoher Minimaldruck erforderlich, um eine möglichst heisses Brühgetränk zu erhalten, andererseits wird bei zunehmendem Druck die Durchlaufgeschwindigkeit des Wasserdampfes mit der Folge vergrössert, dass das Getränkepulver nur an-, aber nicht optimal durchtränkt wird. Hier setzt die Erfindung an.The water vapor is moved in one direction from the bottom to the lid by the beverage powder. On the one hand, a sufficiently high minimum pressure is required to obtain the hotest possible brewed beverage, on the other hand, the flow rate of the water vapor is increased with increasing pressure, with the result that the beverage powder is only soaked, but not optimally soaked. This is where the invention comes in.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemässe Kapsel nach dem Oberbegriff des Hauptanspruchs so auszubilden, dass das Getränkepulver optimal zur Herstellung des Brühgetränks genutzt wird.The invention has for its object to design a generic capsule according to the preamble of the main claim so that the beverage powder is used optimally for the production of the brewed beverage.

Diese Aufgabe wird bei einer gattungsgemässen Kapsel nach dem Oberbegriff des Hauptanspruchs erfindungsgemäss durch dessen kennzeichnenden Merkmale also dadurch gelöst, dass im Bereich des Bodens ein durch eine (bodennahe und deckelferne) Trennwandung von dem Innenraum begrenzter Einströmraum vorgesehen ist, dass der Innenraum ein bezüglich des Bodens aufgerichtet verlaufendes Zentralrohr aufweist, dass um das Zentralrohr herum ein Hohlzylinderabschnitt unter Bildung eines radial inneren sowie eines radial äusseren Ringraums angeordnet ist, dass der innere Ringraum auf seiner dem Einströmraum abgewandten und dem Deckel zugewandten (deckelnahen und bodenfernen) Seite verschlossen ist und dass sowohl das Zentralrohr als auch der Hohlzylinderabschnitt mit Abstand zu dem Deckel enden.This object is achieved in a generic capsule according to the preamble of the main claim according to the invention by its characterizing features in that in the area of the floor there is an inflow space delimited by a partition wall (near the floor and away from the lid) from the interior that the interior is in relation to the floor The central tube has an upright shape, that a hollow cylindrical section is arranged around the central tube to form a radially inner and a radially outer annular space, that the inner annular space is closed on its side facing away from the inflow space and facing the cover (near the cover and away from the ground) and that both The central tube and the hollow cylinder section end at a distance from the cover.

Dabei zeichnet sich die Erfindung gemäss einer ersten Ausführungsform dadurch aus, dass das Zentralrohr an seiner bodennahen Seite mit dem Einströmraum verbunden und an der deckelnahen Seite verschlossen ausgebildet und dort mit radialen Durchtrittsöffnungen versehen und der Hohlzylinderabschnitt sowohl in seinem bodennahen Ende mit Abstand von der Trennwandung unter Belassen einer Verbindung des inneren mit dem äusseren Ringraums angeordnet als auch jeder Ringraum von dem Einströmraum abgetrennt ist.According to a first embodiment, the invention is characterized in that the central tube is connected to the inflow space on its side near the bottom and is closed on the side near the cover and is provided with radial through openings there, and the hollow cylinder section is spaced from the partition wall both in its end near the bottom Leaving a connection of the inner to the outer annular space arranged as well as each annular space is separated from the inflow space.

So bewegt sich bei dieser erfindungsgemässen Ausführungsform der Wasserdampf zunächst in den Rohrabschnitt und von dort über den inneren und danach den äusseren Ringraum zu dem perforierten Deckel. Wegen der Umlenkungen ist der Weg des Wasserdampfes etwa doppelt so lang wie beim gattungsgemässen Stand der Technik mit der Folge einer besseren Ausnutzung des Getränkepulvers und auch eines intensiveren Geschmacks des Brühgetränks. Dabei kann der radial äusseren Ringraum von der Wandung gebildet sein. Zweckmässigerweise kann die Kapsel liegend in die Brühvorrichtung eingesetzt werden. Bei gleicher Form und Dimension wie bei der Gattung kann die erfindungsgemässe Kapsel in denselben, für die bekannten Kapseln dienende Brühvorrichtung eingesetzt und dann auch genutzt werden, wenn deren Dampflanzen nach dem Öffnen des Bodens in den Einströmraum münden.In this embodiment according to the invention, the water vapor first moves into the pipe section and from there via the inner and then the outer annular space to the perforated cover. Because of the deflections, the path of the water vapor is approximately twice as long as in the prior art of the generic type, with the result that better use is made of the powdered drink and also a more intense taste of the brewed beverage. The radially outer annular space can be formed by the wall. The capsule can expediently be inserted horizontally into the brewing device. With the same shape and dimension as in the genus, the capsule according to the invention can be used in the same brewing device used for the known capsules and can also be used if their steam lances open into the inflow space after the bottom has been opened.

Es ist zwar eine in umgekehrter Richtung wie bei der Erfindung nämlich vom Deckel zum Boden von Wasserdampf durchströmte Kapsel bekannt ( WO2017/068535A1 ), die ein bezüglich des Bodens aufgerichtet verlaufendes Zentralrohr aufweist, dessen eine offene Seite von dem Deckel nach aussen hin verschlossen, aber über radiale Öffnungen nach innen offen und mittels einen inneren Abschlusses in Richtung auf seine andere, entgegengesetzte hin Seite verschlossen ist. Mit dem anderen Ende des Zentralrohrs wird zugleich der Boden der Kapsel verschlossen. Allerdings wird das Zentralrohr nicht, wie bei der Erfindung, vollständig von dem Wasserdampf durchströmt. Mit einer Dampflanze wird der Deckel durchstossen und die eine offenen Seite des Zentralrohrs mit Wasserdampf beaufschlagt, der über die nahen radialen Öffnungen in das Innere der Kapsel gelangt. Zugleich geschieht zweierlei: zum einen wird dabei die faltbalgartige konusförmige Wandung unter Verringerung der Höhe der Kapsel zusammengeschoben; zum anderen wird das andere Ende des Zentralrohrs aus der Kapsel geschoben und diese dabei geöffnet, so dass das gebrühte Getränk herausfliessen kann.A capsule through which water vapor flows from the lid to the bottom is known in the opposite direction to that of the invention ( WO2017 / 068535A1 ), which has a central tube which is erected with respect to the floor, one open side of which is closed from the lid to the outside, but is open to the inside via radial openings and is closed by means of an inner closure in the direction of its other, opposite, side. The bottom of the capsule is closed at the other end of the central tube. However, as in the invention, the central tube is not completely flowed through by the water vapor. The lid is pierced with a steam lance and water vapor is applied to one open side of the central tube, which reaches the interior of the capsule via the nearby radial openings. At the same time, two things happen: firstly, the bellows-like conical wall is pushed together while reducing the height of the capsule; on the other hand, the other end of the central tube is pushed out of the capsule and this is opened so that the brewed beverage can flow out.

Zweckmässige Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Appropriate refinements and developments of the invention are characterized in the subclaims.

Die bezüglich der Achse A rotationssymmetrische, im Querschnitt kreisförmige Kapsel 1 der ersten Ausführungsform gemäss Figur 1 weist einen Innenraum 2 auf, der zwischen einem Boden 3 und mit einem dazu entgegengesetzt angeordneten, den Innenraum 2 dicht verschliessenden, an sich bekannten Deckel 4 angeordnet ist. In dem Innenraum 2 befindet sich ein Getränkepulver 5 für die Zubereitung einer Portion eines heissen Brühgetränks wie Kaffee, Tee oder Boullion bei der Durchleitung von Wasserdampf. Die Kapsel 1 ist mit einer konusförmigen Wandung 31 zwischen dem Boden 3 und dem Deckel 4 versehen, wobei der eben ausgebildete Boden 3 über einen Kegelstumpf 32 in die konusförmige Wandung 31 übergeht.The capsule 1 which is rotationally symmetrical with respect to the axis A and has a circular cross section in accordance with the first embodiment Figure 1 has an interior 2, which is arranged between a base 3 and with an oppositely arranged cover 4, which seals the interior 2 tightly and is known per se. In the interior 2 there is a beverage powder 5 for the preparation of a portion of a hot brewed beverage such as coffee, tea or boullion when water vapor is passed through. The capsule 1 has a conical wall 31 between the Bottom 3 and the cover 4 provided, the floor 3 just formed merges into the conical wall 31 via a truncated cone 32.

Im Bereich des Bodens ist ein durch eine bodennahe und deckelferne Trennwandung 6 von dem Innenraum 2 abgegrenzter Einströmraum 7 vorgesehen, der jegliche Form aufweisen kann. Ferner weist der Innenraum 2 ein bezüglich des Bodens 3 aufgerichtet verlaufendes Zentralrohr 8 auf, in das der Einströmraum 7 mündet und das an seinem bodenfernen und deckelnahen sowie dem Einströmraum abgewandten Ende mittels eines Abschlusses 9 geschlossen ist. In dem erstgenannten Fall kann der Einströmraum 7 als sich konusförmig an das Zentralrohr anschliessender Abschnitt ausgebildet sein. Im zweitgenannten Fall weist das Zentralrohr 9 in dem bodenfernen und deckelnahen sowie dem Einströmraum 7 abgewandten Bereich radiale Durchtrittsöffnungen 10 auf. Das Zentralrohr 8 kann weiterhin im Bereich zwischen seiner bodennahen, mit dem Einströmraum 7 verbundenene Seite und seiner deckelnahen verschlossenen 9 Seite mit einer -im Betrieb von einer Dampflanze der Brühvorrichtung als zentrale Wasserdampfzufuhr durchstossbaren- Platte 81 versehen sein. Bei dieser Ausgestaltung kann der Boden 3 im Bereich des Einströmraums 7 bzw. des Zentrahlrohrs 9 auch offen ausgebildet sein.In the area of the floor, an inflow space 7, which can be of any shape and is delimited from the interior 2 by a partition wall 6 near the floor and away from the cover, is provided. Furthermore, the interior 2 has a central tube 8 which extends upright with respect to the base 3, into which the inflow space 7 opens and which is closed by means of a closure 9 at its end remote from the floor and close to the cover and away from the inflow space. In the former case, the inflow space 7 can be designed as a conical section adjoining the central tube. In the second-mentioned case, the central tube 9 has radial through openings 10 in the region remote from the floor and near the cover and away from the inflow space 7. The central tube 8 can furthermore be provided in the region between its side near the floor, connected to the inflow space 7 and its closed 9 side close to the lid, with a plate 81 which can be penetrated by a steam lance of the brewing device as the central water vapor supply during operation. In this embodiment, the base 3 can also be designed to be open in the area of the inflow space 7 or the central tube 9.

An dem bodenfernen und deckelnahen sowie dem Einströmraum abgewandten Ende ist um das Zentralrohr 8 herum ein Hohlzylinderabschnitt 11 unter Bildung eines radial inneren 111 sowie eines radial äusseren Ringraums 112 angeordnet. Hierbei ist der innere Ringraum 111 auf seiner dem Einströmraum 7 abgewandten und dem Deckel 4 zugewandten Seite verschlossen und an seinem bodennahen Bereich mit Abstand von der Trennwandung 6 mit dem äusseren Ringraum 112 so verbunden, wobei jeder Ringraum 111, 112 von dem Einströmraum 7 durch die Trennwandung 6 abgetrennt ist. Sowohl das Zentralrohr 8 als auch der Hohlzylinderabschnitt 11 enden mit Abstand zu dem Deckel 4.At the end remote from the floor and near the cover and away from the inflow space, a hollow cylindrical section 11 is arranged around the central tube 8, forming a radially inner 111 and a radially outer annular space 112. Here, the inner annular space 111 is closed on its side facing away from the inflow space 7 and facing the cover 4, and is connected to the outer annular space 112 at its region near the floor at a distance from the partition wall 6, each annular space 111, 112 being separated from the inflow space 7 by the Partition 6 is separated. Both the central tube 8 and the hollow cylinder section 11 end at a distance from the cover 4.

Diese Kapsel 1 wird dann in eine an sich bekannte und nicht gezeigte Brühvorrichtung eingesetzt, wobei der Deckel 4 unter Bildung des Austritts für das Brühgetränk perforiert und der Boden 3 mittels Dampflanzen zu dem Einströmraum 7 geöffnet und darüber Wasserdampf in einer Richtung von dem Boden zu dem Deckel durch das Getränkepulver 5 unter Erzeugung des heissen Brühgetränks presst, das durch die Perforation des Deckels 4 unter Zurückhaltung des Getränkepulvers 5 in ein Gefäss z.B. eine Tasse fliesst.This capsule 1 is then inserted into a brewing device which is known per se and is not shown, the lid 4 being perforated to form the outlet for the brewed beverage and the base 3 being opened to the inflow space 7 by means of steam lances and water vapor in one direction from the base to the Presses the lid through the beverage powder 5 to produce the hot brewed beverage, which, for example, is retained by the perforation of the lid 4 while retaining the beverage powder 5 in a vessel a cup flows.

Die zweite Ausführungsform der erfindungsgemässen Kapsel nach Figur 2 unterscheidet sich von der ersten dadurch, dass die Trennwandung 6 unter Vergrösserung des Volumens des Einströmraums 7 mit dem Bereich des Übergangs der Wandung 31 zu dem Kegelstumpf 32 verbunden ist, was beim Einleiten des Wasserdampfs von Vorteil sein kann.The second embodiment of the capsule according to the invention Figure 2 differs from the first in that the dividing wall 6 is connected to the region of the transition of the wall 31 to the truncated cone 32 by increasing the volume of the inflow space 7, which can be advantageous when introducing the water vapor.
