Description

The invention relates to a beverage preparation device according to the preamble of claim 1 for producing beverages from beverage substrate capsules, in particular coffee capsules, with an injection device for injecting water into a beverage substrate capsule (for leaching and / or dissolving beverage substrate present in the beverage substrate capsule, for example granules, syrup, Tea leaves or ground coffee) for beverage production and with water supply means for supplying the injection device with water, in particular heating means of the beverage preparation device heated water or cooled with coolants of the beverage preparation device water or with water to ambient temperature, wherein the injection device comprises a first injection chamber part, preferably translationally, relative to a, preferably stationary, second injection chamber part is adjustable.

Furthermore, the invention relates to a system with a beverage preparation device and a beverage substrate capsule according to claim 7 and a method according to claim 10.

For processing rigid beverage substrate capsules, so-called open injection chamber beverage preparation devices have become known in which the beverage substrate capsule forms part of the injection chamber to seal against two opposed injection chamber parts. For this purpose, two injection chamber parts which are adjustable relative to one another are each supported by a seal opposite one another in a closing relative position or end position of an adjustment path of the first injection chamber part on the beverage substrate capsule and thus seal an inlet or injection area and an opposite outlet area from the surroundings. In addition, so-called closed injection chamber systems are known in which the injection chamber parts are completely sealed in the final position against each other.

From the EP 2 405 790 A1 a beverage preparation device has become known in which the beverage substrate capsule is fed via a sloping chute to a fixed injection chamber part, whereupon the injection chamber is closed by means of a further, opposite injection chamber part, which is translationally displaced along an adjustment axis to the beverage substrate capsule having, stationary injection chamber part.

In known capsule machines is considered disadvantageous that a loading position in which a beverage substrate capsule is usually supplied manually, directly with the injection position, in particular brewing position, in which then injected into the beverage substrate capsule water to produce a drink agrees what the constructive and functional possibilities of known beverage preparation devices (capsule machines) limited. There is a desire for a falling apart of a loading position for, in particular manual, loading of an injection chamber part and the actual injection position, in particular brewing position. However, such devices would have the inherent disadvantage that, if the beverage substrate capsule is not inserted correctly and slipping / tilting of the beverage substrate capsule, problems may occur during an adjustment movement, in particular tilting of the beverage substrate capsule during an adjustment movement, thereby blocking further advancement of the beverage substrate capsule. Based on the aforementioned prior art, the invention is therefore an object of the invention to provide a capsule-based beverage preparation device, in the loading position and injection position, in particular Brühposition (end position), preferably along an adjustment, fall apart and still trouble-free operation is ensured - in particular, a tilting a beverage substrate capsule in the beverage preparation device on the way to the end position are at least largely avoided to allow trouble-free operation or a comfortable and trouble-free operation. Furthermore, the object is to provide a corresponding system comprising in addition to a beverage preparation device according to the invention at least one beverage substrate capsule and an operating method for a beverage preparation device according to the invention (capsule machine).

This object is achieved with regard to the beverage preparation device having the features of claim 1, d. H. in a generic beverage preparation device characterized in that the first injection chamber part has a beverage capsule receptacle with which this is adjustable between a loading position and an end position, and that the first injection chamber part stationarily arranged, resilient positioning means are assigned, which are designed and arranged such that they pass through Adjustment of the first injection chamber part with a beverage substrate capsule received in the beverage capsule receptacle along the adjustment path from the loading position in the direction of preferably an injection position of the beverage substrate capsule corresponding end position are elastically deflectable (in particular by direct or alternatively at least indirect interaction with the beverage substrate capsule).

With regard to the system, the object is achieved with the features of claim 7.

Advantageous developments of the invention are specified in the subclaims. All combinations of at least two features disclosed in the description, the claims and / or the figures fall within the scope of the invention.

In order to avoid repetition, features disclosed in accordance with the device should also be regarded as disclosed according to the method and be able to be claimed. Likewise, according to the method disclosed features should be considered as device disclosed and claimed claimable.

The invention is based on the idea to provide the beverage preparation device with fixed, ie elastically deflectable, positioning means and to form and arrange them in such a way that the first injection chamber part with its beverage capsule receptacle and a beverage substrate capsule receivable or received therein is adjustable relative to these positioning means in that, by adjusting the beverage substrate capsule along the, preferably, but not necessarily, purely translational adjustment path from the loading position in the direction of the end position, the positioning means are preferably deflectable from a rest position by direct, alternatively indirect interaction with the beverage substrate capsule and thus act on the beverage substrate capsule by spring force. Preferably, the beverage substrate capsule and the positioning means cooperate in such a way that the beverage substrate capsule is spring-loaded in the direction of its beverage capsule receptacle. In other words, the beverage preparation device according to the invention comprises fixedly arranged, resilient positioning means which are deflectable by adjusting the first injection chamber part with a beverage substrate capsule from the loading position in the direction of the end position, thereby spring beaufeaufschlagbe the beverage substrate capsule. In other words, stationary spring means (resilient positioning means) according to the invention are provided, which are adjustable by adjusting a beverage substrate capsule in the direction of the second injection chamber part from the adjustment (reversible), in particular by direct or at least indirect interaction with the beverage substrate capsule to spring force the beverage substrate capsule. The positioning effect results, on the one hand, from the application of the spring force and, as will be explained later, in addition to the fact that the positioning means, which is advantageously provided in a further development of the invention, are designed and arranged such that they serve as insertion aid for the beverage substrate capsule in that they prevent a beverage substrate capsule which can be received in the beverage capsule receptacle from falling out of the beverage capsule receptacle (into the adjustment path) when the first injection chamber part is in the loading position. In another embodiment, the positioning means in the invention are arranged relative to the beverage capsule receptacle and preferably a beverage substrate capsule arranged or arrangeable therein, the latter being tilted about a tilting axis preferably perpendicular to an adjustment axis of the first injection chamber part, preferably in a horizontal plane Positioning would abut, which thus prevent further tilting or tipping out of the beverage capsule recording safe. In order to ensure this, it is preferred if the positioning means are spaced a distance from a beverage substrate capsule inserted into the beverage capsule receptacle in the loading position, so that it can tilt to a minimum, namely until it stops against the positioning means (without blocking into the adjustment path). In an alternative embodiment, the positioning means are arranged such that they already contact the beverage substrate capsule during the insertion process or after the insertion process, even if the first injection chamber part is still in the loading position be that the positioning means touch the beverage substrate capsule tension-free or spring force free when located in the loading position first injection chamber part or alternatively already act there with a spring force be that the positioning means by the insertion process of the beverage substrate capsule a little far - not completely - arranged resiliently deflectable or positioned relative to the beverage substrate capsule. It is very particularly preferred if the positioning means are designed in such a way that they preferably prevent and dispose of a previously described dumping of the beverage substrate capsule not only in the first injection chamber part located in the loading position, but also (still) during the further adjustment movement in which the beverage substrate capsule, in particular after a springing back of the positioning, can be supported on the positioning means, ie slide along them or prevent the positioning means after moving out of the loading position due to a small distance to the beverage capsule receptacle and an extension of the positioning along the adjustment tipping in that the beverage capsule holder tilts against the positioning means in the case of any tilting movements, preferably about a tilting axis mentioned above, which then causes further tilting and thus safely prevent it from tipping out of the beverage capsule holder.

The embodiment of the beverage preparation device according to the invention has particular advantages if the beverage preparation device is configured in the invention with a so-called open injection chamber, in which the beverage substrate capsule thus forms a part of the injection chamber and the two Injektionskammerteile in the final position of the first Injektionskammerteils, especially at both opposite end faces the beverage substrate capsule, sealingly lie and preferably are not completely sealed against each other, but in particular an upper distance (opening) between them, it being particularly preferred if the positioning extend along this upper distance. Especially in such beverage preparation devices with an open injection chamber would be a, in particular purely translational, alternatively rotatory or combined translational and rotational adjustment of the beverage substrate capsule on the way to the final position relative to the positioning of the beverage substrate capsule relatively undefined. The provision according to the invention of the spring-trained, stationary positioning means reliably prevents the beverage substrate capsule from tipping out into the adjustment path of the first injection chamber part.

With regard to the specific design of the positioning means, there are different possibilities. It is particularly expedient if the resilient positioning means have a resilient arm extending preferably along the adjustment path, the free end of which is oriented in the direction of the loading position, so that the free end, in the radial direction outwards relative to an adjustment axis of the beverage substrate capsule, can be deflected and preferably the beverage substrate capsule after a spring back of the resilient arm can be supported on the resilient arm, in particular in an unwanted Verkippbewegung. It is particularly preferred if a plurality of such resilient arms are provided, whose free ends are resiliently deflectable in the radial direction by contact with the beverage substrate capsule, in particular to come to rest in a spring back behind a peripheral collar of the beverage substrate capsule. It is particularly preferred if the at least one resilient arm has a run-on slope in order to prevent a hard abutment of the beverage substrate capsule axially against the resilient arm and to convert the applied from the beverage substrate capsule along an adjustment axis on the resilient arm axial pressure force in a radial deflection force ,

In principle, other embodiments of the positioning means are possible - it is essential that these by a force applied to the beverage substrate capsule during its adjustment in the direction of its injection position, d. H. in the direction of the second injection chamber part are resiliently adjustable out of the adjustment. Thus, for example, it is conceivable to realize a resilient arm without a free end, in the manner of a leaf spring, in which the resilient action on the beverage substrate capsule results from a deformation of the spring in a region between two fixed ends. Preferably, such a spring is curved convex and therefore already offers due to their shape an oblique ramp surface for the beverage substrate capsule at their adjustment.

Depending on the configuration and arrangement of the positioning these act after a preferred then only partial spring back by Federkraftbeaufschlagung with the beverage substrate capsule in their further adjustment or act on the beverage substrate capsule according to an alternative embodiment after springing back with a spring force, preferably also in the last described variant, a possible distance between the beverage substrate capsule and the positioning means is selected so that a tipping out of the beverage substrate capsule from their beverage capsule removal even after a spring-back of the positioning is reliably prevented.

The positioning means are very particularly preferably a plastic part, in particular a plastic injection-molded part, which even more preferably forms part of a guide frame for the first injection chamber part, on which the second injection chamber part is formed. Alternatively, it is also conceivable to provide metallic positioning means and to arrange them in a stationary manner relative to the first injection chamber part.

It is particularly preferred if the beverage preparation device has retaining means with which the beverage substrate capsule is retractable in the direction of its loading position when the first injection chamber part is moved back (together with the beverage capsule holder), it being particularly preferred if these retaining means are in the region of the end position of the first Injection chamber part or the injection position of the beverage substrate capsule are arranged. In other words, retaining means are provided in a further development of the invention against which the beverage substrate capsule is adjustable in the loading position when the injection chamber part is moved back, so that the retaining means virtually pull out the beverage substrate capsule from the beverage capsule holder. The positioning means are preferably such arranged to the retaining means that they already earlier on the adjustment of the beverage substrate capsule in the direction of the end position, either already directly in the loading position or preferably after covering a short adjustment of preferably less than 1 cm, more preferably less than 5 mm, with an in come into contact with the beverage capsule absorbed beverage substrate capsule.

The feature of the preferred arrangement of the retaining means in the region of the end position of the first injection chamber part is to be understood that according to a preferred embodiment, the retaining means already interacting in the injection position of the beverage substrate capsule or at least approximately the injection position of the beverage substrate capsule cooperate with the beverage substrate capsule, ie the beverage substrate capsule does not have to be moved back a long distance from the end position with the first injection chamber part. Thus, the beverage substrate capsule may be ejected in its injection position or at least immediately adjacent to the injection position or may fall out there through a, preferably lower, ejection opening. The falling out may preferably be purely gravity-induced or power-assisted, in particular by means of a drive or a spring biased in particular by closing the injection chamber. It is particularly preferred for the beverage substrate capsule for restrained interaction with the retaining means less than 2 cm, preferably less than 1 cm, more preferably less than 0.5 cm, in particular between 0 and 0.3 mm, preferably between 0.05 and 3 mm, must be adjusted back to the loading position before the retaining means grip and hold back the beverage substrate capsule, which can then fall down after moving out of the first injection chamber part.

It is particularly expedient if the retaining means comprise at least one retaining spring element, preferably two spaced, in particular opposing and even more preferably mirror-symmetrical formed and / or arranged retaining spring elements, wherein the at least one retaining spring element, in particular the plurality of retaining spring elements are formed and arranged such that this / this by adjusting the first injection chamber part together with the beverage substrate capsule from the loading position in the direction of the end position before reaching the end position and after contacting the positioning means elastically, in particular relative to an adjustment axis in the radial direction outward, is deflectable / and after passing at least a portion of the beverage substrate capsule is zurückfederbar / are, in particular behind a radial projection, preferably a, preferably cover-side, circumferential collar of the beverage substrate capsule el, in any case such that upon a return movement of the first injection chamber part in the loading position, the beverage substrate capsule from the first injection chamber part by means of the at least one retaining spring element is stripped by supporting the beverage substrate capsule to the retaining means or strippable. To be particularly advantageous, it has been found that the at least one retaining spring element is part of a stamped and bent part, in particular in the form of a notch from this sheet metal, wherein even more preferably the sheet extends in the direction of a preferably translational adjustment axis of the injection chamber part and the Notch radially inward towards the beverage substrate capsule has.

The invention also relates to a system comprising a beverage preparation device designed according to the concept of the invention and a beverage substrate capsule which can be inserted into the beverage capsule receptacle in the loading position and can be positioned during the adjustment of the first injection chamber part from the loading position to the end position by interaction with the stationary, resilient positioning means is. Preferably, the beverage substrate capsule and the positioning means are coordinated and positioned relative to each other and dimensioned so that the beverage substrate capsule in the loading position befindliches first injection chamber part in the radial direction relative to a longitudinal center axis of the beverage substrate capsule or perpendicular to a capsule bottom and a capsule lid and / or overlapping in relation to a, preferably coinciding with the longitudinal central axis, adjustment axis of the first injection chamber part, in particular by means of a, preferably cover-side, circumferential collar and thereby resiliently deflects or displaces the positioning means in an adjustment of the beverage substrate capsule by means of the first injection chamber along the displacement in the radial direction, whereby the beverage substrate capsule is spring-loaded and the adjustment is free. Particularly preferably, the positioning means are also designed such that they spring back radially after passing through a beverage substrate capsule, in particular a aforementioned circumferential collar, either such that they rest spring force or powerless after springing back the beverage substrate capsule in their further adjustment in the direction of the first injection chamber part, so in that the beverage substrate capsule can slide along the positioning means without spring force application or according to a further alternative after springing back from the beverage substrate capsule, preferably only a short distance, so that the beverage substrate capsule then (or only then) comes into contact with the positioning means when the beverage substrate capsule (a short distance) tips out of the beverage capsule receptacle, which in turn prevents further tilting and falling out of the beverage capsule receptacle into the adjustment path by the positioning means.

The beverage preparation device designed according to the concept of the invention and / or the system according to the invention can be operated as follows. It is envisaged that a beverage substrate capsule is first inserted into the beverage capsule receptacle when the first injection chamber part is in the loading position. Depending on the configuration and arrangement of the positioning means, the beverage substrate capsule already contacts the positioning means in the loading position or, alternatively, is still spaced a distance, in particular less than 1 cm, more preferably less than 0.5 cm from the positioning means. In any case, the beverage substrate capsule and the positioning act on an adjustment movement of the first injection chamber part, in particular a purely translational adjustment in the direction of the second Injektionskammerteils along the Verstellweges together so that the positioning means are resiliently deflected by applying force by means of beverage capsule receptacle and thus spring-loaded the Getränkekapselaufnahme. After reaching the injection position of the beverage substrate capsule or the end position of the first injection chamber part is then injected into the beverage substrate capsule for preparing a drink of water, which may have been heated depending on the configuration of the beverage preparation device with heating means of beverage preparation device or alternatively has been cooled by means of integral cooling means or alternatively Ambient temperature has.

The positioning means preferably spring back in the direction of the end position upon further displacement of the beverage substrate capsule, in particular after passing through a peripheral collar of the beverage substrate capsule, wherein it is particularly preferred if the beverage substrate capsule glides along the positioning means along the positioning means, in particular without application of spring force, after springing back during the further adjustment movement and / or, in particular only after tilting, comes into contact with these.

Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawings.

These show in:

1 to 7b : Operation of a preferred embodiment of a beverage preparation device according to the invention.

In the figures, like elements and elements having the same function are denoted by the same reference numerals. In 1 is a sectional plan view of a detail designed as a so-called capsule beverage preparation device 1 shown.

Concretely illustrated is an injection device 2 the beverage preparation device 1 in which water enters a beverage substrate capsule 3 can be injected.

The injection device 2 includes a, here purely translational along an adjustment axis V adjustable, first injection chamber part 4 which is relative to a second, here fixed, injection chamber part 5 is adjustable, between the in 1 loading position shown (loading relative position) and the in 5 shown end position (injection position of the beverage substrate capsule), then in the water in the beverage substrate capsule 3 injectable and a finished beverage from the beverage substrate capsule 3 is derivable.

Merely for the sake of completeness it should be mentioned that for reasons of clarity in the figures the per se known, preferably at least one pump comprising water supply means are not shown. These supply the injection device, in the concrete embodiment, the second injection chamber part 5 , Water, in particular in the beverage preparation device heated or cooled water, which from a water tank or from a fresh water supply line, in particular by means of the pump, to the injection device 2 can be conveyed in a conventional manner. Also not shown are integral opening means for opening the beverage substrate capsule 3 when closing the injection chamber to inject the water and to be able to discharge a finished drink again. This diversion process is carried out in the specific embodiment preferably in the region of the first injection chamber part 4 which is not shown, for example, together with the first injection chamber part 4 is associated with adjustable spout.

In the concrete embodiment, it is a so-called open injection device 2 in which the injection chamber parts 4 . 5 not fully in the end position of the first injection chamber part sealingly abut each other, but the beverage substrate capsule in the final position clamped record between them and are sealed against this, in which case a free opening remains on an upper side. In one lower area is a sealing element 6 which can be seen here by way of example at the first injection chamber part 4 is arranged and in the end position on the second injection chamber part 5 sealingly abuts to avoid uncontrolled leakage of flushing medium in a flushing down - the injection chamber, as mentioned above, is open or is in an inserted beverage substrate capsule 3 sealed over this, while in an alternative feasible injection device this is sealed by the fact that the injection chamber parts 4 . 5 are completely sealed against each other and completely enclose the beverage substrate capsule.

Predominantly, the first injection chamber part has 4 a section of the seal 6 made beverage capsule pickup 7 on, in the loading position, in particular manually, from the vertical direction from above a beverage substrate capsule can be inserted.

The first injection chamber part are fixed, resiliently deflectable positioning devices designed as loading or insertion aids 8th which, as will be explained later, prevent the beverage substrate capsule 3 from the beverage capsule holder 7 in the adjustment of the first injection chamber part 4 can tilt into it.

After loading of the first injection chamber part 4 with the beverage substrate capsule 3 is, as will be explained below, the first injection chamber part 4 , here purely translational, adjusted in the direction of the second injection chamber part 5 to. It will be explained later retention means 9 for the beverage substrate capsule 3 happens. The here exemplary and preferably purely translational adjustment movement of the first injection chamber part 4 is here exemplified manually (alternatively electric motor) actuated. In the concrete embodiment, this is actuation means 10 provided with an axial displacement force in the direction of the second injection chamber part 5 can be acted upon. The actuating means 10 pass through a fixed abutment in the loading position 11 with an axial extension 12 ,

The abutment 11 is, in particular detachable, arranged between two guide arms 25 a frame construction on which the second injection chamber part 5 is trained. The adjusting movement is realized so that initially a pure adjustment takes place by Axialkraftbeaufschlagung. After reaching an intermediate position are the axial processes 12 through the abutment 11 guided and supported on the back, ie on one of the second injection chamber part 5 away from the abutment. By turning the actuating means 10 Inclined surfaces turn backwards at the axial processes 12 as well as on the abutment 11 against each other, creating the first injection chamber part 4 is further moved along the adjustment axis V from the located near the end position or injection position intermediate position in the final position and at the same time the injection chamber, more precisely, the first injection chamber part 4 , locked or secured against a return movement by pure Axialkraftbeaufschlagung. To move back must first by turning back the actuating means 10 a release done. The adjustment described above is a preferred - but the invention is not limited -; It is essential, at first, only that the first injection chamber part 4 , in particular translational, but not necessarily translational, from a loading position into an end position relative to the second injection chamber part 5 is adjusted.

Based on 2a and 2 B Now, a preferred embodiment and a preferred mechanism of action of the resilient positioning 8th described.

As is clear from the 2a and 2 B results, in the specific embodiment, the stationary positioning means according to a preferred embodiment variant part of the guide arms 25 However, may also be formed as a separate, in particular fixed to the guide frame components.

In the concrete embodiment, the stationary positioning means comprise 8th two parallel oriented spring arms 13 . 14 (see 1 In principle, an embodiment with only one spring arm can be realized. The spring arms 13 . 14 extend parallel to the adjustment axis V and each have a free, oriented in the loading position end 15 . 16 on, which each with a run-on slope 17 . 18 is provided to an axial displacement movement of the beverage substrate capsule 3 along the adjustment axis V convert into a later to be explained, radial resilient deflection movement of the positioning 8th ,

In 2a it can be seen that the beverage substrate capsule 3 in the loading position of the first injection chamber part 4 without force of the positioning 8th from the vertical direction from above into the beverage capsule holder 7 can be inserted. As it turned out 2 results are the positioning means 8th and are especially the free ends 15 . 16 such relative to the beverage substrate capsule 3 arranged that these, as in 2 B is indicated, not tilt out of the loading position in the drawing plane left in the adjustment along the adjustment axis V and thus an adjustment of the first injection chamber part 4 can block. In other words, the Beverage substrate capsule 3 after a slight tilting movement about an imaginary tilting axis K, which lies in a horizontal plane and extends vertically to the adjustment axis V, with an upper edge to the positioning means 8th abut, so that further tilting is prevented. In an alternative variant, not shown, the beverage substrate capsule touches 3 the positioning means 8th already during loading of the beverage capsule holder and / or immediately after loading, even when the first injection chamber part is in the loading position, alternatively without or under bias of the positioning means 8th ,

In the 3a to 3b is now the further adjustment of the beverage substrate capsule 3 or the first injection chamber part 4 along the adjustment axis V in the direction of the second injection chamber part 5 explained. During this adjustment, the beverage substrate capsule comes 3 in adjusting contact with the positioning means 8th , more precisely the free ends 15 . 16 , wherein due to the realization of the aforementioned starting slope 17 . 18 the axial force is converted into a radial deflection, here a slight resilient bending of the positioning 8th in the radial direction, so that the positioning means 8th release the further adjustment path towards the end position. Specifically, the beverage substrate capsule comes 3 with a lid-side circumferential collar 19 in adjusting contact with the positioning means 8th ,

As it turned out 3b results, feather the positioning 8th after passing the free ends 15 . 16 through the perimeter covenant 19 in the radial direction inwards. Due to their relative positioning, the beverage substrate capsule nevertheless tilts out 3 from the beverage capsule holder 7 safely prevented as the beverage substrate capsule 3 , here with a rear area, back to the positioning 8th would bump. In an alternative embodiment, not shown, the positioning means spring 8th far enough back that the beverage substrate capsule 3 along the positioning means 8th can slide to reach the final position (either still spring loaded or spring force free).

After passing the free ends 15 . 16 the positioning means 8th , more precisely the spring arms 13 . 14 happens the beverage substrate capsule 3 as based on the 4a and 4b it can be seen, the stationary restraint means. This adjustment movement is in 4a indicated. The first injection chamber part can be seen 4 , which is further adjusted in the direction of the arrow along the adjustment axis V. The beverage substrate capsule passes by 3 retention means realized as notches of feather sheets which are from the beverage substrate capsule 3 More specifically, the aforementioned, radially outwardly projecting circumferential collar 19 , are deflected radially outward in the respective arrow directions and after passing through the circumferential collar 19 snap back.

4b shows a preferred embodiment of the retaining means 9 , Evident are designed as stamped sheet metal sheets 20 . 21 that with notches 22 . 23 are provided, which are produced in the stamping bending process.

In 5 is the first injection chamber part 4 along the adjustment axis V axially adjusted in the end position. For reasons of clarity, the positioning means 8th not shown. In the final position is the beverage substrate capsule 3 sealed against the first and the second injection chamber part 4 . 5 , To recognize the restraining means 9 , which are pivoted back radially inward. In the illustrated, locked position of the injection device 2 Now, the water injection can be done in a conventional manner. The beverage substrate capsule 3 was opened in a manner known per se by opening means which are preferably designed as a cutting means during the closing process of the injection chamber.

6a now shows the return movement along the adjustment axis V of the first injection chamber part 4 , At the same time, the beverage substrate capsule becomes 3 first a little way, especially just a few millimeters, together with the first injection chamber part 4 moved back and then relies on the arranged in the end position retaining means 9 to and with the circumferential collar 19 , At the in 6b shown further adjustment movement of the injection chamber part 4 along the adjustment axis V is the beverage substrate capsule 3 completely restrained and then, as can be seen from a synopsis of 7a and 7b results, through a lower ejection opening 24 fall out down.
