    [001] The present invention relates to extraction apparatus for the preparation of beverages or the like of an extraction material contained in a capsule, for example, ground coffee. The invention relates in particular to an infusion module for an extraction apparatus, as well as to an extraction apparatus with such an infusion module.
    [002] Extraction apparatus for preparing beverages or the like from an extracting material available in a portion pack are known among other things as coffee machines or espresso machines. In many corresponding systems the portion packs are designed as capsules, in which the extracting material, for example, is hermetically sealed. For extraction, the capsule is perforated, for example, on two sides that are opposite each other. On the first side, then, an extraction fluid - usually hot water - is introduced. On the second side, the extraction product is discharged out of the capsule. This takes place in a so-called infusion module. A module of this type has an infusion chamber in which the capsule is received. Infusion modules are particularly required, in which the capsule is launched into the infusion module, and the infusion chamber is closed, for example, by means of an operating lever, in the case of a repeated opening of the chamber. infusion after the infusion process, the capsule is automatically removed out of the infusion chamber and is ejected into a capsule container. Infusion modules of this type, with automatic capsule ejection, are generally executed as horizontal infusion modules, that is, the insertion of the capsule occurs from above, the closing of the infusion chamber is a relative horizontal movement of two parts of the Infusion chamber, the infusion fluid essentially passes horizontally, and the capsule container is formed below the infusion chamber.
    [003] In the case of infusion modules of this type, it must be ensured that the launched capsule is held until the infusion chamber is closed, in such a way that, however, it falls when the infusion chamber is opened again after the process of infusion. Patent document WO 2008/014830 shows - for capsules in essence, cup-shaped with a collar protruding laterally - one possible way, how this can be caused. The infusion module described there has lateral retaining arms on a portion of the infusion module. In the retaining arms, first and second guide grooves are formed. During insertion, the collar is guided on both sides through the first guide grooves, these first guide grooves having a limitation towards the bottom, through which the launched capsule is stopped. During closing of the brewing chamber, the retaining arms are swiveled away, in such a way that their connection to the capsule collar is completely loosened. The capsule is held in this state, in which it is held in one run like the cup of the other part of the brew module. In the case of repeated opening of the brewing chamber, the retaining arms are swiveled back inwards, are able to re-engage with the capsule and act as a restoring means whereby a restoring boss moves the collar of the capsule into the second grooves -guide. These slots are open towards the bottom, in such a way that the capsule drops out as soon as the brewing chamber is completely open.
    [004] This solution conditions that a relatively more pronounced side collar is available. Furthermore, it is relatively expensive to perform.
    [005] EP 2 105 074 shows an brewing module with a positioning unit, which likewise has retaining jaws connected with one of the brewing module parts and moved together with guide grooves, through which the capsule collar is guided laterally during insertion. In this case, the guide grooves form a guide channel, which is executed by converging downwards and squeezing at the lower end. During closing of the brewing chamber, the collar abuts against a retaining edge of the other part of the brewing module, and as a result is bent or bent and thus released from the guide grooves. A rear cut of the retaining jaws supports the ejection of the capsule during opening of the infusion chamber after the infusion process.
    [006] This solution also conditions a relatively more pronounced lateral collar, which, moreover, needs to be deformable - in an axial direction. Therefore it is not suitable for all types of capsules.
    [007] Starting from the state of the art, the invention presents the task of providing an infusion module for an extraction apparatus, for example, a coffee machine, for the preparation of a drink in portions, or other Extraction product from an extraction material packed in a capsule, which overcomes the disadvantages of existing infusion modules, and which makes possible a simple and compact construction form as well as great flexibility in the design of the capsule. The infusion module should be suitable, in particular, for horizontal mounting and preferably also for large infusion pressures of above 1 MPa (10 bar), for example up to 2 MPa (20 bar), where, also markedly lower infusion pressures of, for example, about 0.1 MPa (1 bar) are not excluded.
    [008] According to a first aspect, the infusion module has a first part of the infusion module and a second part of the infusion module movable in relation to that part, the first and second part of the infusion module form a discharge device for discharging an extraction product out of the capsule, and an injector for inserting an extraction fluid into the capsule - for example, part of the infusion module is the discharge device and the second part of the infusion module is the injector - or vice versa. In a closed position (the first and second parts of the infusion module are, for example, "together") an infusion chamber is closed which at least partially surrounds the capsule during the infusion process.
    [009] For the opening and closing of the infusion chamber, the second part of the infusion module can move linearly with respect to the first part of the infusion module along an axial direction - that is, translational, or in essence, in a translational way. A pivotal movement of the parts of the brewing module relative to one another is not excluded, but is generally unnecessary. In particular, in embodiments during closing of the infusion chamber, the capsule is not actively rotated. It can also be foreseen that during closing the capsule does not tip either, that is, the orientation of the capsule remains, in essence, maintained when closing the infusion chamber.
    [0010] The first part of the infusion module has a head with lateral (capsule) guide means. These means are attached to the head, and are connected with it. The lateral guide means define a first track, essentially vertical, a collar of the capsule, which can be formed, for example, by a weld bead or the like. The guide means in an upper area of the first track each have a first retaining structure which opposes movement of the collar from the first track inwards. In addition, the brewing module part forms a support, which runs below the track in the insertion direction and prevents the capsule from falling downwards when the capsule collar is guided along the first track. The first track can be formed, for example, by a first guide groove. The support can be formed by a delimitation of the first guide groove - or in general of the first track - towards the bottom.
    [0011] In this text, generally the concepts "internal" and "external" refer to axial directions towards the center of the infusion chamber or away from it. Axial directions are directions along the essentially horizontal axis of the injector discharge device, which can also correspond to an axis of the capsule. These radially horizontal directions with reference to this axis are referred to through the concepts "radially inward" and "radially outward". "towards the top" and "towards the bottom" designate the corresponding vertical directions in a proposed use of the brewing module, in which the coffee machine with the brewing module is placed on a horizontal surface.
    [0012] The collar of the capsule can be, for example, a conventional, pronounced and peripheral collar projecting onto the plane of one of the end surfaces. However, it can also be less pronounced according to an alternative cap shape, and can be executed, for example, as a peripheral weld bead/weld edge, for example, as what is known as caps according to the document WO 2010/118543.
    [0013] The second part of the infusion module has restoration means, which during the opening of the infusion chamber (i.e., during the separation movement of the first and second part of the infusion module) grip the collar in order to move that necklace through the opening move to the second lane.
    [0014] The lateral guide means can be fixed and rigidly connected with the head, that is, in essence, immobile in relation to this head. This can be particularly favorable with regard to manufacturing and maintenance technology. In this case, for example, during the process all the lateral guide means remain laterally immobile in relation to the head. Also during the brewing process, the lateral guide means remain, for example, in contact with the capsule. During displacement out of the first track and eventually through the first track away to the second track, then the capsule is deformed slightly, for example by means of radial deformation. In particular the collar, for example rigidly in itself, can be pressed almost slightly radially inward.
    [0015] But it is also possible that the lateral guide means can be deflected (a little) outwards as opposed to a spring force. Therefore, during displacement of the capsule in relation to the lateral guide means, instead of a capsule or in addition to this, a deviation of the lateral guide means can occur.
    [0016] Complementarily or alternatively, during the brewing process also the restorative means can remain in engagement with the capsule. Thus, for example, during the infusion process the capsule collar can be in a reception formed by the restoration means, in which during the subsequent opening of the infusion chamber it is also moved together, until it manages to reach the second track .
    [0017] Thus, like the lateral guide means, the restoration means cannot also move laterally, but can be fixedly in a housing of the second part of the brewing module. However - irrespective of a possible deflection capacity of the lateral guide means - it is possible that the restoration means can be deflected radially as opposed to a spring force.
    The guide means can be arranged, for example, on both sides of the fork-shaped capsule, and each can have a reception for the collar of the capsule. The lateral guide means then have, for example, two parts of the guide means each, between which the restoring means grip when the brewing chamber is closed, and/or the restoring means grip from above and from above. low on the capsule.
    [0019] In an embodiment with the infusion chamber that completely surrounds the capsule, an interior of the infusion chamber is defined through the surrounding elements of the first and second part of the infusion module - for example, possibly including sealing -. The lateral guide means and/or the restoring means then meet with the infusion chamber closed inside the infusion chamber - in the same way as a seal of the possibly existing capsule.
    [0020] This approach differs from the prior art according to which the means, which keep the capsule in an intermediate position after insertion, in the case of closing the infusion chamber need to be removed, for example, through a movement of hinge out or down. The approach according to the invention therefore enables a construction with a minimum of moving parts, which is favorable both with regard to reliability and also with regard to manufacturing costs.
    [0021] In the case of closing the infusion chamber, the collar of the capsule can be moved in the direction of the first track through the second part of the infusion module outwards, that is, to the head of the first part of the infusion module. In this infusion position, the capsule - caused already before the infusion process or through the internal pressure formed in the capsule during the infusion process - is pierced by piercing elements of the first part of the infusion module. During opening, then, the capsule is withdrawn from that position through the restoration means, until the collar manages to reach the second track. From there the capsule can then fall into a capsule container.
    [0022] In particular, it can be provided that the second track with respect to the brewing chamber is arranged further inwards - i.e. on the side of the second part of the brewing module closer than the first track. Then, under circumstances, during opening of the brewing chamber the collar of the capsule can be pulled from the brewing position through the first track away to the second track.
    [0023] As an alternative to this arrangement, it can also be provided that the second track with respect to the brewing chamber is arranged further outward - that is, at the head of the first part of the brewing module - closer than the first track. Then during closing of the infusion chamber, the capsule collar is moved from the insertion position through the second track away to the infusion position.
    [0024] On the inner side of the second track - this holds for the two relative arrangements of the first and the second track - for example, there is a second retaining structure, which during the opening movement retains the collar of the capsule, so that necklace has reached the second clue. The holding force of this movement is then greater than the corresponding force of the restoration means, such that the collar in the case of further opening manages to come out of reception of the restoration means. This can be caused, for example, by the fact that this retaining structure protrudes more radially inward, forms a steeper angle to the shaft, and/or is dilated. Additionally or alternatively to this it can also be provided that the restoring means grips in the center (relative to the verticals) of the collar of the capsule, while the second retaining structure engages from the top and bottom. In the case of an essentially cubic or cuboid shaped capsule this means that the retaining structure grips closer to the corners and edges of the capsule, where this capsule leads to more deformation resistance than the restorative means.
    [0025] The discharge device and the injector are preferably arranged opposite each other, and have, for example, a perforation device on the extraction side with at least one perforation element, projecting into the chamber of infusion, or a piercing device on the injection side, likewise with at least one piercing element protruding into the infusion chamber. The perforation elements, for example for drilling the walls of thermoformed synthetic material capsules, are made, for example, of polypropylene with, for example, a thickness of between 0.2 mm and 0.5 mm or 0.4 mm , for example, between 0.25 mm and 0.35 mm; as such they differ under circumstances of means for perforating aluminum capsules. However, piercing devices for capsule wall materials other than thermoformed synthetic materials may also be available.
    [0026] The infusion module injector features a capsule seal in embodiments, which grips the capsule along a peripheral side surface. The capsule seal may feature a - single - sealing lip, which is executed by protruding into the fluid injection site. As an option on the injector, an inflow channel may be available, which diverts infusion water injected already before the start of the infusion process to the sealing of the capsule, and lets the seal - in particular, the sealing lip - compress against the surface of coating.
    [0027] As described, for example, in WO 2012/045184 - a seal of the capsule can also cause retention and positioning of the capsule in the closed infusion chamber. Retaining the capsule in the brewing chamber by means of a peripheral seal among other things has the advantage of greater production tolerances, i.e. the elasticity of the capsule seal can absorb inaccuracies in the relative positioning of the first and second part of the module. infusion.
    [0028] Also optionally on the extraction side (on the discharge device side) a seal can be available. According to an alternative, the sealing of the capsule, however, is not caused by such an additional seal, but by the sealing effect of the capsule wall pressed against an inelastic sealing surface. In this case, the sealing surface can be a curved or even flat surface, and the sealing effect can be supported by a deformation capacity of the hot capsule wall during the brewing process.
    [0029] Another optional feature refers to a mechanism for the movement of the second part of the brewing module in relation to the first part of the brewing module (the relative movement may contain a movement of the second part of the brewing module and/or of the first part of the brewing module with respect to a stationary housing). According to a form of execution, a movement triggering - for example, an operating lever or also an electric drive, respectively with or without reduction or multiplication of the gear - is transmitted to an articulation lever, with a joint of The pivot lever pivot is superimposed during closing, i.e. in the closed state of the brewing module it is on the other side of that plane, which is defined by the respectively outer rotation axes of the pivot lever arms as in the open state of the infusion module.
    [0030] An overlap of this type - in the closed state of the brewing module against a stop - has a self-locking effect: due to the internal pressure that arises during the brewing process, the brewing module parts are pressed separately, whereby the Pivot lever is pressed further against the backrest - the infusion chamber cannot open automatically.
    [0031] These optional features (lip sealing with inflow channel; sealing on the extraction side by means of non-elastic sealing surface; pressed-in hinge lever) work together - each by itself or in combinations - in a particularly favorable way with the concept described above. However, they by themselves - likewise each by themselves or in combinations - can also be used in other infusion modules for an extraction apparatus, which have a first infusion module part and a second infusion module part. mobile brewing in relation to that part, the first and second parts of the brewing module forming a discharge device for discharging an extraction product from a capsule with extracting material for the preparation of brewed beverages, and an injector for inserting an extraction fluid into the capsule.
    [0032] According to a special embodiment, for example, the infusion chamber is designed to receive a capsule that conically widens in contrast to the state of the art, not to the discharge or injector side, but of a capsule, for example cubic or cuboid in shape. As a cubic or cuboid shape is meant in this case, a shape that does not diverge too much from the geometrically exact Cubic or Cubic shape, in such a way that they would be functionally very different; for example, the shape of a truncated pyramid is included with rectangular or square base surface, whereby the side surfaces adjacent to the base surface are slanted relative to the perpendicular to the base surface around only a small angle of inclination. α, of, for example, at most 2°. The cuboid or cubic shape can have a peripheral collar - for example, in the form of a weld edge / a weld bead - which protrudes laterally, for example, by a maximum of 1.5 mm and is projected, for example, from a plane of end surfaces.
    [0033] As already mentioned, the brewing module is executed as a horizontal brewing module. However this does not exclude the fact that the brewing module can be arranged slightly tilted as a whole, for example it can be tilted downwards towards the first part of the brewing module. The inclination of the axis of the nozzle discharge device towards the horizontal is then preferably at most 15°, in particular between 0° and 10°.
    [0034] In embodiments, the infusion chamber completely surrounds the capsule, that is, the first part of the infusion module and the second part of the infusion module have elements that correspond precisely to each other, and in the closed position they form together the infusion chamber. The wall parts formed by the first part of the brewing module, and the wall parts formed by the second part of the brewing module can be sealed together in the closed position, for example, by means of a peripheral closure seal. This closure seal can have, for example, a lip seal, which is fixed to one of the parts of the brewing module, and during closing the brewing chamber abuts against a surface of the other part of the brewing module. A closed infusion chamber of this type provides a flush of the extraction device or infusion module, without a capsule having to be placed - which is a marked advantage for the user. This, however, does not preclude the use of a rinse or site-retaining capsule during the rinsing or cleaning process - with the infusion chamber closed or not completely closed.
    [0035] Through such a closure seal the infusion chamber can be sealed in two stages. A first sealing stage is formed by at least one capsule seal, which surrounds the capsule and prevents introduced extraction fluid or discharged extraction product from flowing through the capsule. This first sealing stage seals the capsule against the injector or discharge device. As a second sealing stage, the closure seal seals the parts of the brewing module from one another. On the one hand, it can serve as a complementary seal during the brewing process during the brewing process. On the other hand, as mentioned, it can serve for sealing during a washing process.
    [0036] Additionally object of the invention is a process for the infusion of an infusion drink by employing a capsule. This process is carried out, for example, with an infusion module or with an extraction apparatus, of the type described above and may comprise the steps: - insertion of a portion capsule with an extraction material, for example, through an opening insert positioned such that a collar of the capsule is positioned on the first track, and that the capsule is seated on the holder; - closing the infusion chamber by moving the second part of the infusion module relative to the first part of the infusion module, such that the capsule is pierced through at least one piercing element of an injector formed by the first and/ or by the second part of the brewing module, through which inlet openings in the capsule appear; - introduction of an extraction fluid into the capsule through the inlet openings (eg hot water using a pump and optionally a valve); - discharge of the extraction fluid out of the capsule, through the discharge openings, which have been produced by the piercing elements, of a discharge device formed by the first and/or the second part of the brewing module; following discharge, opening of the infusion chamber by moving the second part of the infusion module relative to the first part of the infusion module, whereby the capsule is extracted from the first part of the infusion module through the restoration elements, until allowing the collar to be positioned along the second track and continuing the opening process until the capsule drops out of the downwardly open infusion chamber.
    [0037] In addition, an extraction apparatus, in particular, a beverage preparation machine, for example, coffee machine or tea machine, with a water tank or water connection, with a water heater, is an object of the invention. water, a water pump, and an infusion module of the type described, whereby the water tank, the water heater and the water pump are connected to the infusion module in such a way that the heated water carried by the pump can be introduced into the capsule through the injector.
    [0038] Examples of implementation of the invention will be described below, with the aid of drawings. In the drawings like reference numerals designate like or similar elements. The drawings show elements partially corresponding to each other, from figure to figure at different scales. They are shown:

    [0052] In figures 18-20, a cross-sectional representation of the discharge device, parts of the capsule, the discharge device and the injector during various stages of opening the infusion chamber.
    [0053] The infusion module according to figures 1 and 2 presents an infusion module housing 1 and secured or guided through the housing a discharge device 3 as the first part of the infusion module and an injector 5 as the second part of the infusion module. Through an operating lever 6 the injector 5 can move between an open position, in which the infusion chamber is open and the operating lever is on top, and a closing position, in which the infusion chamber is closed and the operating lever is bent down with respect to the housing and the first part of the brewing module. Figures 1 and 2 show the brewing module in the open position and with the capsule 10 released. For insertion of the capsule 10 there is an insertion opening 11, which also defines the orientation of the capsule during insertion. The insertion opening shows through indication of the position of the collar of the capsule 21 also the orientation of the capsule to be chosen.
    [0054] In the discharge device, lateral guide means 31 are available - molded as guide jaws - whose function will be described in more detail below.
    [0055] The conversion of the tilting movement of the lever (operating lever 6 can be pivoted around an axis defined by rotation pins 7) into a translational movement of the injector 5 is available in a pivoting lever 8. A headstock closure 9 fixed to the lever for torsionally is interlocked for this purpose with one of the arms 8.1 of the articulation lever.
    [0056] As is clearly visible in Figure 3, the pivot lever is executed in such a way that it forms a self-locking system, whereby the pivot lever in the closed state of the brewing module, when the operating lever 6 is on the backrest, it is superimposed around a few degrees, i.e. articulation articulation is when the operating lever 6 is on the lower backrest, on the other side of that plane 13, which is defined by the respectively outer rotation axes of the arms 8.1, 8.2 as in the open state of the infusion module. Therefore, during a separate compression of the two parts of the brewing module during the brewing process, the hinge lever is compressed in the housing against a stop, and cannot open independently.
    [0057] A microswitch 16 may also be available, which is shown in Figure 4, which is actuated by means of the compression of the articulation lever in the backrest and, for example, can then automatically form the backrest itself. The microswitch 16, which controls that certain processes - in particular the infusion process itself - can only be carried out with the infusion chamber closed.
    [0058] Alternative arrangements of a microswitch of this type are also possible, in which this microswitch respectively queries the state of closing of the infusion chamber.
    [0059] Figure 5 shows - in another orientation compared to the figures described above - the injector and the discharge device. Figures 6 and 7 show other views of the discharge device 3.
    [0060] The lateral guide jaws 31 protrude from the head 30 of the discharge device 3 towards the injector (i.e. inwards according to the terminology used here). In the illustrated example they are each divided into a part of the upper and lower lateral guide jaws with an interruption between them. By means of the lateral guide jaws 31 a first track 33, in this case external and a second track 36, in this case internal, are defined. The outer and inner races are respectively defined by structures in the form of grooves, which are made to guide the collar 21 of the capsule (in the example of embodiment shown, the collar 21 is formed by a peripheral weld edge), whereby, the tracks are dimensioned in such a way that the capsule collar still has slack and is therefore not tight. The outer guide track is positioned with respect to the insertion opening 11 in such a way that the collar 21 of the capsule launched with the infusion chamber open is able to reach the first track 33. On the underside of the first track 33 a support 35 is formed. over which the collar 21 and/or another part of the capsule 10 manages to stay when that capsule is thrown. In contrast, the second track 36 is open to the bottom.
    [0061] In an alternative embodiment to the embodiment shown, the two slots can also be interchanged - that is, the first track is then located further out than the second track, which will be described in more detail in follow.
    [0062] In an alternative embodiment to the embodiment shown, also instead of engaging laterally between the parts of the guide jaws 31, the restoration means 61 can engage from the top and bottom. In such a configuration, therefore, for example, in fig. 5 the inner injector parts disposed inside the brewing chamber are rotated about 90° about the axis of the brewing chamber.
    [0063] The way in which the retaining jaws work and the joint action with the restoration means 61 of the injector 5 will be described in detail with the help of figures 8 to 12.
    [0064] Figure 8 shows a sectional representation of the state after insertion of the capsule. Collar 21 is located on the outer race. On the upper side the outer retaining structure supports the collar and prevents the capsule from tipping down and inwards, i.e. in the orientation drawn to the left. During closure of the infusion chamber, the injector is moved to the discharge device and the restorative element moves to the interruption between the upper and lower guide-jaw parts. The capsule - guided by a capsule seal further described in more detail below - is dragged a little away and, for example, is slightly pierced by piercing elements (extraction pins 39) on the extraction side (figure 9) .
    [0065] Then, the infusion process takes place, in which hot water is introduced into the capsule under pressure, and the extraction product is discharged on the extraction side. For unloading, for example, a perforation device 38 such as that which is the subject of European patent application 13 185 359.0 can be used. Other drilling and discharging devices can also be employed, for example according to WO 2010/118544.
    [0066] During the opening of the infusion chamber a drag part 62 of the restoration element 61 grips the collar of the capsule 21, and thus moves the capsule away from the extraction pins 39. Due to the fact that the restoration element protrudes into the area of the trailing part 62 more radially inward than the first retaining structure 34 (outer), the restoring element moves the collar from the capsule outward also through the outer race (figure 10). In this case, the capsule is slightly deformed as a whole, such that the collar - generally of relatively stable dimensions - may deviate radially inward slightly. This can be favored by the fact that after the brewing process, in general, the capsule is still hot and therefore the capsule material can be deformed better than at room temperature. However, the principle also works with the cooled capsule.
    [0067] On the inner side of the second track 36, a second retaining structure 37 is molded. This structure protrudes radially further inward than the first retaining structure 34 and/or is made at a steeper angle to axis 20 and/or is more dilated and/or is disposed more to the top/more to the bottom than the first retaining structure 34, such that the retaining effect (the force that would need to be expended in order to force the capsule away, moreover) is greater than that force of the first retaining structure 34.
    [0068] The retaining effect of the second retaining structure 37 is also greater than that (acting in the opposite direction) of the drag part 62. in the central part of the capsule, in contrast the second retaining structure 37 grips above and below it and closer to the corners of the capsule. Since as a whole, this capsule manifests a capsule deformation with more resistance than the central part of the capsule, it deflects the latter inwards and thus allows a downward sliding of the drag part 62 (figure 11).
    [0069] After the capsule retained by the second retention structure 36 is completely released from the receptacle formed by the injector 5 (figure 12) it may fall into a capsule container downwards.
    [0070] It is not necessary that the first track 33 is defined by groove-shaped structure as in the illustrated example. On the contrary, under circumstances it is sufficient when on the upper side a first retaining structure 34 is available, which supports the collar 21 from the inner side and thus prevents a tipping into the capsule by lifting on the support. Complementarily or alternatively the inner race can be defined only by retaining structures of the type of the interior retaining structure 36.
    [0071] A detail of the closing head 9 is illustrated in figure 13. This head forms a cover 17 that follows the rotation movement of the lever, through which a user is prevented from engaging the infusion unit mechanism - of this This way the danger of injury is minimized.
    [0072] During the infusion process the capsule is gripped by an injector capsule seal, which also keeps this capsule in position. Such a capsule seal can be molded as described in WO 2012/045184; express reference is made to that publication.
    [0073] Figure 14 shows the infusion module with a seal of the capsule 40, which is performed as a simple lip seal in embodiment of the principle according to WO 2012/045184, which is performed by projecting into the location of fluid injection, such that the fluid pressure of the fluid entering from the injection side further compresses the sealing lip against the capsule.
    [0074] The injector 5 presents a perforation device 51 on the injection side with a multitude of perforation elements 53.
    [0075] A particularly optional feature of the injector 5 is similarly visible in Figure 14. In this case, it is an inflow channel 41, which favors a fluid flow towards the sealing of the capsule 40, although the capsule is pressed against the injector. By this measure the seal of the capsule has flowed against already before the water has penetrated into the capsule - therefore, before the brewing process.
    [0076] A seal of the capsule 10 against the discharge device in this case works optionally without a separate seal on the extraction side. Such a seal is necessary so that the brewing beverage leaving the capsule can reach the pouring device and cannot drip down into the capsule. In the embodiment described here, according to a special aspect of the invention, a sealing surface 32 adapted to the shape of the capsule is provided on the extraction side, against which the capsule is pressed extensively during the extraction process. In this case, this sealing surface can be made of a hard material - for example, injection molded hard plastic or metal - it is the wall of the capsule that can be deformed during the brewing process, and which is compressed by sealing against the sealing surface 32.
    [0077] Another optional feature of the injector 5 is seen, for example, in figures 1 to 3. A 3/2-way valve is fixed with the aid of a geometry, which is injected directly into the injector - that is, the valve 15 is available directly on the injector and not as known from the prior art, for example, connected to this injector through a hose or similar. The 3/2-way valve features a pump-side (inlet) connection, an injection (outlet)-side connection, and a water drip connection (alternative outlet). As is well known, the 3/2-way valve serves to relieve the infusion chamber. In the non-activated state, the brewing chamber is relieved, whereby one port of the connection on the injection side is open for the water drip connection. In the activated state, the input path is free for the connection on the injection side and the water drip connection is closed. After the end of the infusion process, the valve goes back to the non-activated state, and allows pressure reduction from the connection on the injection side by dripping water into a drip tray. In this case, the connection on the pump side is closed, which also prevents post-evaporation due to a sudden pressure drop after the infusion process.
    [0078] Figure 15 shows a cross-sectional representation of the discharge device. Next to the elements already described above there is seen a closure seal 70, which in this case, like the seal of the capsule 40, is configured as a lip seal. In the closed state of the infusion chamber, this seal abuts on the injector housing 5, and during admission with pressure it is pressed against this housing. This seals the brewing chamber and prevents the leakage of water too so when - for example for a washing process - no capsule is placed.
    [0079] Similarly in Fig. 15, a flexible nozzle 81 arranged behind the extraction side is visible. This mouthpiece can be made, for example, of silicone or another material compatible with food and elastic, and it can have a mouthpiece opening of, for example, between 0.15 mm and 0.4 mm, in particular between 0 .2 mm and 0.3 mm.
    [0080] Among other things, such a mouthpiece has the effect that the brewing beverage is further frothed, such that the formation of the preferred "cream" is favored.
    [0081] Figure 16 likewise shows parts of the dispensing device 3 in a cross-sectional representation, in which, next to the spout 81, the dispensing device 83 for the brewing beverage is also visible. In figure 18 an optional form of the flexible nozzle 81 is also seen: on the inlet side this nozzle has an area entering towards the opening of the nozzle, which channels the fluid flow.
    [0082] The discharge device 3 according to figures 17 to 20 differs from those of the above figures in that the first track 33 is arranged inside and the second track 36 is arranged outside. Correspondingly also the arrangements of the first retaining structure 34 and the second retaining structure 37 are interchangeable. The elevation (rib), which forms the second retaining structure 37 in this case, external, has on the inner side a relatively flat ramp 48 towards the first track 33.
    [0083] The capsule launched into the brewing module, as in the embodiment described above, is held guided by the first track 33 and is seated on the support. During the closing of the infusion chamber, the collar of the capsule is displaced out of the first track, through the ramp 48 and through the second track it moves outwards towards the head 30. In this embodiment, during the infusion process the means Restoration keys 61 of the injector also remain engaged with the capsule.
    [0084] After the infusion process, during the opening of the infusion chamber, in the same way, the drag part 62 of the respective restoration element will engage with the capsule collar (fig. 18) and thus during the opening of the pins of extraction 39 the capsule is removed (fig. 19). The second retaining structure 37 is executed in such a way that the retaining effect is greater than that of the drag part 62, such that the capsule collar remains suspended there when the injector is moved further away (fig. 20) such that the collar of the capsule remains suspended on the second track 36 and may fall out.
