    State of the art
    [0001] The present invention relates to an infusion device for extracting a portion capsule with a first infusion chamber element and a second infusion chamber element, the first infusion chamber element being movable between a loading position, in which the first and second infusion chamber elements are spaced apart, and an extraction position, in which the first and second infusion chamber elements are close together to form a essentially closed infusion.
    [0002] These infusion devices are generally known. For example, EP 2 077 087 A1 discloses an infusion device for a portion capsule, comprising a second infusion chamber element in the form of a housing element with a hollow compartment for housing the portion capsule and a first infusion chamber element in the form of a closure element for closing the hollow compartment. The closure element then comprises an injection arrangement for introducing extraction liquid into the portion capsule, while the housing element comprises an extraction arrangement for discharging the extraction liquid from the portion capsule by interacting with a beverage substance disposed in the portion capsule to discharge the extraction liquid from the portion capsule by interacting with a beverage substance disposed in the portion capsule and to add a beverage preparation to a drinking container. For filling the infusion device with the portion capsule, the closure element is brought to a loading position, where it is spaced from the housing element. Then, the portion capsule is inserted into an intermediate compartment between the housing element and the closure element, and then the closure element is moved towards the housing element along an axial direction, thereby the portion capsule is inserted into the hollow compartment of the housing element. The housing element and the closure element form in the extraction position an essentially closed infusion chamber for the extraction of the portion capsule. The beverage substance especially comprises roasted or instant coffee to be extracted. Furthermore, it is known to equip these infusion devices with piercing means, which pierce the portion capsule for introducing the extraction liquid or for discharging the drink extract during or after the closure of the infusion chamber.
    [0003] Disadvantageously, in such infusion devices there is a danger that the portion capsule when introduced into the intermediate compartment between the first and the second infusion chamber element will remain pending in the piercing means of the first infusion chamber element, in so that an error-free portion of the capsule is not possible. A portion capsule inserted or not positioned correctly can then lead to malfunction of the infusion device.
    [0004] The purpose of the invention is to provide an infusion device for the extraction of a portion capsule, which does not present the disadvantages of the current state of the art and allows the introduction of the safer portion capsule without error in relation to the current state of the art . Description of the Invention
    [0005] This objective is achieved, according to the invention, by an infusion device for extracting a portion capsule with a first infusion chamber element and a second infusion chamber element, the first chamber element being The infusion chamber is movable between a loading position, in which the first and second infusion chamber elements are spaced apart, and an extraction position, in which the first and second infusion chamber elements are brought together to formation of an essentially closed infusion chamber, the infusion device being executed in such a way that, when moving between the loading position and the extraction position, the first infusion chamber element performs a linear displacement along an axial direction, when the first and second infusion chamber elements are spaced apart, and additionally performs a rotation movement around an axis of rotation pe rpendicular to the axial direction, when the first and second infusion chamber elements are at least partially approximated to each other.
    [0006] In this way, it is possible that the first infusion chamber element is aligned inclined at least in the loading position with respect to the second infusion chamber element and, when moving from the loading position to the extraction position, especially shortly before reaching the extraction position, be brought into alignment corresponding to the second infusion chamber element.
    [0007] Advantageously, due to the inclination of the first infusion chamber element in the loading position, the danger that the portion capsule, when introduced in the intermediate compartment between the first and the second infusion chamber element, remain pendent on the first infusion chamber element and especially on the first piercing means of the first infusion chamber element. In the event of a hasty application of the infusion device by a user, often the closing mechanism is already activated to move the first infusion chamber element from the loading position to the extracting position, although the portion capsule is not yet correctly positioned in the middle position. This would produce a keying of the portion capsule between an adduction opening for the portion capsule and the first infusion chamber element, when the first infusion chamber element already at the beginning of the movement from the loading position to the extraction position would be perpendicularly aligned and / or would have been initially rotated perpendicularly. In the infusion device according to the present invention, the danger of keying is reduced, since when the closing mechanism is activated, the first infusion chamber element remains initially in an inclined position and is displaced only axially towards the second infusion chamber element. The alignment of the first infusion chamber element only occurs clearly later, when the portion capsule is spaced apart especially before the adduction opening towards the second infusion chamber element. Preferably, the first infusion chamber element during the pivoting motion is pivoted at an angle between 1 and 30 degrees, especially preferably between 1 and 15 degrees and particularly well, preferably at essentially 6 degrees. Preferably, the first infusion chamber element when moving from the loading position to the extraction position is initially displaced exclusively linearly along the axial direction towards the second infusion chamber element, then in addition to the linear displacement along from the axial direction towards the second infusion chamber element still around the axis of rotation (which also migrates along the axial direction) and then again exclusively linearly displaced along the axial direction towards the second infusion chamber element infusion. The extreme area of the first infusion chamber element, in the loading direction, is preferably so inclined with respect to the plane perpendicular to the axial direction that the distance between the first and the second infusion chamber element is maximum in the vicinity of the adduction opening. The axial direction preferably extends in a horizontal plane, that is, perpendicular to the gravitational field.
    [0008] According to another preferred embodiment, it is envisaged that an extreme area of the first infusion chamber facing the second infusion chamber element, in the loading position, is inclined with respect to a plane aligned perpendicularly to the axial direction and, in the position of extraction, it is aligned perpendicularly to the axial direction, so that, advantageously, an essentially airtight sealed infusion chamber is guaranteed to be closed by the first infusion chamber element and at the same time the particularly safe and non-subject introduction of the capsule is made possible. portion transversely to the axial direction. The plane is preferably aligned parallel to the gravitational field of the earth and / or parallel to a loading direction, along which the portion capsule is introduced into the infusion device.
    [0009] According to another preferred embodiment, it is envisaged that the first infusion chamber element by means of lateral guide rails is guided between the loading position and the withdrawing position, the guide rails extending essentially along the axial direction and in a region facing the second infusion chamber element a displacement perpendicular to the axial direction. The lateral guide rails preferably comprise an elongated hole in an infusion device housing wall, the first infusion chamber element being guided by a transverse pin arranged in the elongated hole. By displacing the guide rail, the rotation movement of the first infusion chamber element automatically occurs when the transverse pin passes through the displacement. The displacement is preferably arranged between two segments of the guide rail extending along the axial direction.
    [00010] According to another object or a preferred embodiment of the present invention, it is provided that the infusion device has an adduction opening, which is provided in the loading position for adding the portion capsule between the first and the second infusion chamber element along a loading direction, the first infusion chamber element having an extreme area facing the second infusion chamber element, which in the loading position is aligned inclined with respect to the loading direction, so that Advantageously, the adduction of the easy, safe and non-flawless portion described above is guaranteed. The extreme area in the extraction position is preferably aligned essentially parallel to the loading direction and / or the gravitational field.
    [00011] According to another object or a preferred embodiment of the present invention, it is provided that the first infusion chamber element has at least one capsule stop for retaining the portion capsule, which is rigidly joined with the first infusion chamber element and which is arranged along the gravitational field essentially below the infusion chamber. Advantageously, the portion capsule is then removed by the capsule stop when filling the infusion device, when transporting from the loading position to the extraction position and partially when transporting it back from the extraction position. The capsule stopper is preferably made in one piece with the first infusion chamber element, so that a comparatively cost-effective and simple production is obtained. The capsule stop is optionally in one piece or is rigidly joined with the first infusion chamber element.
    [00012] According to another object or a preferred embodiment of the present invention, it is provided that the infusion device has at least one capsule ejector, which is disposed along the gravitational field essentially below the infusion chamber and that, when the first one moves infusion chamber element from the extraction to the loading position produces a scraping of the portion capsule by a capsule stop rigidly joined with the first infusion chamber element. Advantageously, therefore, an automatic ejection mechanism of reliable operation is provided, which ejects the portion capsule when the first infusion chamber element is displaced from the extraction position to the loading position.
    [00013] According to another preferred embodiment, it is provided that the capsule ejector has an arm extending essentially along the axial direction with a free end, the free end having towards the second element of the infusion chamber an essentially stop area perpendicular to the axial direction, which when moving the first infusion element from the extraction position to the loading position produces a scraping of the portion capsule by the capsule stop, and the free end presents on one side opposite the second infusion chamber a guide chamfer which, when the first infusion chamber element is moved from the loading position to the extraction position, allows the portion capsule to remain on the capsule stop. In this way, an automatic capsule ejection mechanism is obtained, which allows safe transport of the capsule from the loading position to the extraction position, safe transport of the capsule back from the extraction position towards the loading position and, in addition, a reliable ejection of the capsule before reaching the loading position again during transport back. The capsule stop is preferably made in such a way that at least one free end of the capsule stop can pivot elastically away from the infusion chamber, that is, especially along the gravitational field, downwards, so that the capsule of the portion can actually move without great resistance together with the first infusion chamber element from the loading position to the pulling position, but when returning from the pulling position to the loading position just before reaching the loading position it comes up against the capsule ejector and then it is displaced from the capsule stop, so that the portion capsule under the action of gravity is ejected from the region between the first and the second infusion chamber elements.
    [00014] According to another preferred embodiment, it is provided that the infusion device is executed in such a way that an orientation of the portion capsule in the loading position is essentially identical to an orientation of the portion capsule in the extraction position, with a cap of portion capsule capsule is preferably aligned parallel to the gravitational field and / or the loading direction. A reorientation of the portion capsule during a movement of the first infusion chamber element from the loading position to the withdrawing position is thus not necessary, so that failures can safely be avoided, which can result for example by a slipping or keying of the portion capsule due to a reorientation of the portion capsule due to a reorientation of the position capsule in the infusion device. The failure of infusion devices is thus reduced.
    [00015] According to another preferred embodiment, it is provided that the first infusion chamber element has first means of perforation, which protrude perpendicularly from the extreme area towards the second infusion chamber element and which are preferably arranged antiparallel to the gravitational field in a region of the extreme area opposite the capsule stop. The extreme area of the first infusion chamber element in the loading direction is preferably so inclined with respect to the plane perpendicular to the axial direction that the distance between the first and the second infusion chamber element in the vicinity of the adduction opening is maximum, so that in this region there is enough space to dispose the first protruding piercing means, without there being a danger of hooking the portion capsule with the first piercing means during the insertion operation.
    [00016] According to another preferred embodiment, it is provided that the infusion device is so executed that the portion capsule during the rotation movement around the axis of rotation is pierced by the first piercing means. Advantageously, the torque of the first rotating infusion chamber element is used to produce the drilling. The required application of force by the user is thus reduced and the comfort of handling the infusion device is increased.
    [00017] According to another preferred embodiment, it is provided that the first element of the infusion chamber comprises a supply device, which in the extraction position is provided for the addition of extraction liquid to the perforated portion capsule by the first means of drilling, so that in the extraction position, the extraction operation can be performed to extract the beverage substance contained in the portion capsule.
    [00018] According to another preferred embodiment, it is provided that the first infusion chamber element is coupled with lateral retaining arms, which engage behind a portion capsule flange and that with the first infusion chamber element are movable at least partially between the loading position and the extraction position along the axial direction. Advantageously, therefore, on the one hand, the maintenance of the portion capsule position towards the horizontal axis in the loading position, as well as during transport from the loading position to the extracting position, is guaranteed. On the other hand, the portion capsule after the extraction operation, when the first infusion chamber element is returned, is pulled back at least partially out of the second infusion chamber element, to enable an ejection of the portion capsule . The retaining arms enclose the capsule flange especially only towards the second infusion chamber element. The retaining arms are optionally in one piece or rigidly joined with the first infusion chamber element.
    [00019] According to another preferred embodiment, the retaining arms (34) are movable along the axial direction relative to the first infusion chamber element and / or that the retaining arms are coupled with a knee lever lever, which is intended for the movement of the first infusion chamber element between the loading position and the withdrawing position. In this way, a fixation of the retention arms is obtained especially compactly in a mounting and stable space. The relative movement between the retaining arms and the first infusion chamber element furthermore allows a distance of the capsule flange from the first infusion chamber element during the return movement of the first infusion chamber element from the withdrawing position. to the loading position. Thus, a frictionless ejection of the portion capsule through the capsule ejector is favored.
    [00020] According to another preferred embodiment, it is provided that the second infusion chamber element has at least a second piercing means, which extends from the second infusion chamber element essentially parallel to the axial direction towards the first infusion chamber element infusion.In an advantageous manner, an extraction of the beverage extract from the serving capsule is thus guaranteed during the extraction operation.
    [00021] According to another preferred embodiment, it is provided that the second infusion chamber element comprises a hollow bell element for housing the portion capsule in the extraction position, with a bottom region of the bell element preferably comprising at least a recess for discharging extraction liquid from the perforated portion capsule by the second piercing means, the second piercing means being preferably disposed in the region of the recess and the recess flowing out, particularly particularly preferably, in a channel outlet to discharge the extraction liquid from the infusion chamber. The recess preferably comprises a support and / or column structure, with which the portion capsule is securely spaced in the region of the recess of the second infusion chamber element. In this way, a reduction in the cross section of the recess through the capsule bottom is prevented, so that a flow of the extraction liquid can be guaranteed at any time.
    [00022] According to another preferred embodiment, it is foreseen that in the extraction position the capsule stop is disposed essentially below the second infusion chamber element and / or in the extraction position the retaining arms are disposed respectively laterally next to the second infusion element. infusion chamber. Advantageously, the second infusion chamber element has corresponding bulges, correspondingly penetrating the capsule stop and / or the retaining arms in the extraction position. In view of the current state of the art, there is therefore no need for the possibility of lateral pivoting of the retaining arms, so that the production expense of the infusion device is advantageously reduced.
    [00023] Another object of the present invention is a process for operating an infusion device, with a portion capsule being introduced between the first and second infusion chamber elements in a first process step and second second process step, the first infusion chamber element is moved from the loading position to the extraction position, and furthermore, during the second process step the first infusion chamber element is linearly displaced initially along in an axial direction and then further rotated about an axis of rotation perpendicular to the axial direction. In this way - as explained above - an easy and error-free adduction of the portion capsule is obtained in the intermediate region between the first and second infusion capsule elements. The danger that the portion capsule will become jammed in the event of a precipitated start-up of the infusion device is especially reduced. Preferably, the first infusion chamber element when moving from the loading position to the extraction position is initially displaced exclusively linearly along the axial direction towards the second infusion chamber element, then pivoted further for linear displacement along the axial direction towards the second infusion chamber element still around the pivot axis (which also migrates along the axial direction) and then again moved exclusively linearly along the axial direction towards the second infusion chamber infusion chamber. When the first element of the infusion chamber is returned from the extraction position to the loading position, these movement steps are carried out precisely in reverse.
    [00024] According to another preferred embodiment, it is provided that in the second process step the first infusion chamber element is moved by the rotational movement of a position, in which an extreme area of the first infusion chamber element facing the second element infusion chamber is inclined with respect to a plane aligned to the axial direction, to a position, in which the extreme area is aligned perpendicularly to the axial direction. In this way, - as explained above - a safe and error-free insertion of the capsule is obtained. Preferably, the first infusion chamber element during the pivoting movement is pivoted at an angle between 1 and 30 degrees, especially preferably between 1 and 15 degrees and particularly preferably at essentially 6 degrees. The extreme area of the first infusion chamber element in the loading position is so inclined with respect to the plane perpendicular to the axial direction that the distance between the first and the second infusion chamber element is maximum in the vicinity of the adduction opening.
    [00025] According to another object or a preferred embodiment of the present invention, it is provided that during the second process step the first infusion chamber element is moved by the rotational movement of a position, in which an extreme area of the first infusion chamber element infusion facing the second infusion chamber element is inclined with respect to a loading direction, along which in the loading position the portion capsule is introduced between the first and second infusion chamber elements, to a position, in that the extreme area is aligned parallel to the loading direction. In this way - as explained above - a safe and error-free insertion of the capsule is guaranteed and a watertight closure of the infusion chamber is obtained during the extraction operation.
    [00026] According to another object or a preferred embodiment of the present invention, it is provided that the portion capsule inserted between the first and the second infusion chamber element is retained by means of a capsule stop, the portion capsule being carried away by means of a capsule ejector out of contact with the capsule stop, while in a third process step the first infusion chamber element is moved from the extraction position to the loading position. Advantageously, an automatic ejection of the portion capsule is thus obtained upon the return movement of the first infusion chamber element from the extraction position to the loading position.
    [00027] According to another preferred embodiment, it is provided that the portion capsule is not taken out of contact with the capsule stop, while in the second process step the first infusion chamber element is moved from the loading position to the extraction position. Advantageously, thus, during the movement of the first infusion chamber element towards the extraction position, an unwanted ejection of a capsule of a portion not yet extracted is avoided.
    [00028] According to another preferred embodiment it is provided that during the second process step the orientation of the portion capsule is kept constant, preferably that the orientation of a capsule cap of the portion capsule is kept parallel to the gravitational field and / or parallel to the loading direction, so that a reorientation of the portion capsule within the infusion device is not required and thus the possibility of infusion device failures is reduced.
    [00029] According to another preferred embodiment, it is provided that in the second process step the portion capsule during or temporally after the rotating movement of the first infusion chamber element is pierced by the first piercing means of the first infusion chamber element. Advantageously, the torque of the first pivoting chamber element is used to produce the drilling. The application of force required for a user is thus reduced and the comfort of using the infusion device is increased.
    [00030] According to another preferred embodiment, it is provided that in the second process step, the portion capsule, when reaching the extraction position, is pierced by at least a second means of piercing the second infusion chamber element, with the piercing being performed by the second means of drilling temporarily after drilling by the first means of drilling. Advantageously, the required application of force for piercing the portion capsule is thus reduced.
    [00031] Another object of the present invention is the use of the infusion device according to the invention for the preparation of hot drinks, especially coffee, milk and / or chocolate.
    [00032] The invention will be explained in detail below on the basis of examples of execution represented in the drawings. The drawings illustrate only exemplary embodiments of the invention, which do not restrict the essential inventive idea.

    [00037] Figures 5a and 5b - show other schematic sectional views of an infusion device according to the second embodiment of the present invention
    [00038] In the different figures equal parts are always provided with equal references and, as a result, as a rule they are also named or mentioned only once.
    [00039] Figures 1a to 1k show schematic cross-sectional views of an infusion device 1 for extracting a portion 2 capsule according to a first embodiment of the present invention. The infusion device 1 then comprises a first infusion chamber element 3 performed as a housing element or partially hollow bell element 21 and a second infusion chamber element 4 performed as a closing element 30 or plunger. The first infusion chamber element 3 is movable relative to the second infusion chamber element 4 along an axial direction 6 between a loading position 17 shown in figures 1a and 1k and an extraction position 11 shown in figure 1f.
    [00040] The portion 2 capsule comprises a cone trunk 31 made of plastic and executed in the form of a pan. The cone trunk 31 is closed air-tight by means of a capsule cover 25 made of plastic or aluminum foil. Within the serving capsule 2 there is a beverage substance, especially a roasted coffee powder extractable by means of an extraction liquid. Optionally, the portion capsule 2 has a filter element not shown, which is spaced from the capsule bottom 29 and disposed between the capsule bottom 29 and the beverage substance. The capsule cap 25 is glued or welded in the region of a capsule flange 27 with the cone stem 31.
    [00041] The first infusion chamber element 3 has, in an extreme area 8 facing the second infusion chamber element 4, a plurality of first piercing means 18. The first piercing means 18 respectively comprise a piercing tip, which protrudes from the extreme area 8 towards the second infusion chamber element 4. Furthermore, in the extreme area 8, water outlet openings are performed (for perspective reasons not identified in figures 1a to 1k), and always precisely one water outlet opening is arranged in the vicinity of a drilling tip. The first infusion chamber element 3 also has a water supply channel 32, which is provided for adding extraction liquid to the water outlet openings. The first infusion chamber element 3 also has, on its underside, a capsule stop 12 rigidly joined and especially in one piece with the first infusion chamber element 3, which is arranged in the extraction position 11 below the infusion chamber 1 'and below the second infusion chamber element 4. In addition, the first infusion chamber element 3 has two lateral retaining arms 34, the free ends of which face each other and hug the flange laterally. capsule 27.
    [00042] The second infusion chamber element 4 has a second piercing means 19, which comprises a punching tip pointing towards the first infusion chamber element 3, which is arranged within the hollow compartment and is preferably joined by a detachable snap closure with the second infusion chamber element 4. The punching tip is provided with side grooves 33, which extend parallel to the axial direction 6. In the region of the punching tip, the second infusion chamber element 4 has a recess 23 in the bottom region 22 of the hollow compartment, into which an outlet channel 24 opens.
    [00043] In figure 1a the first infusion chamber element 3 is shown in the loading position 10, that is, the first infusion chamber element 3 is spaced from the second infusion chamber element 4 along the axial direction 6. In that outlet position then along a loading direction 26 the portion capsule 2 is introduced by an user not shown in an intermediate region between the first and the second infusion chamber element 3, 4. An infusion device housing 1, carried out as part of the second infusion chamber element 4, for this purpose has an adduction opening 42, through which the portion capsule 2 can be inserted. The first infusion chamber element 3 is then tilted to such an extent with respect to the second infusion chamber element 4 that the extreme area 8 is inclined both with respect to the loading direction 26 and also with respect to a plane 9 perpendicular to the direction 6 axial, especially at an angle between 2 and 10 degrees. By this inclination, the region of the first infusion chamber element 3 facing the adduction opening 42 is at the maximum distance from the second infusion chamber element 4, so that the portion capsule 2 is insertable in the intermediate region, without then there is a risk of hooking the portion 2 capsule with the first piercing means 18.
    [00044] In figure 1b it is illustrated that the portion 2 capsule under the action of gravitational force falls laterally into the region between the first and the second infusion chamber element 3, 4 and there it rests on the capsule stop 12. Simultaneously , by means of the lateral retaining arms 35, tipping of the portion capsule 2 towards the second infusion chamber element 4 is prevented, as the capsule flange 27 is supported towards the second infusion chamber element 4 in the arms retainer 35, so that the portion capsule 2 is essentially aligned axially along the axial direction 6. The capsule cap 25 as well as the capsule bottom 29 are therefore aligned essentially parallel to the plane 9 and the loading direction 26. By tilting the first infusion chamber element 3, contact between the first means is largely avoided hole 18 and the capsule cap 25. The capsule stop 12 optionally has an edge on its free outer end that prevents unwanted slipping of the capsule flange 27 from the capsule stop 12. In addition, the capsule stop 12 remains preferably slightly inclined towards the loading direction 26. The capsule ejector 5 has a free end, which extends along the plane 9 at least partially at the same height with the capsule stop 12 and thus also with the flange capsule 27. On one side opposite the second infusion chamber element 4, the free end has a guide bevel 15 inclined with respect to plane 9, so that the capsule flange ula 27 can be displaced from the first infusion chamber element 3 simply by the capsule ejector 5 towards the second infusion chamber element 4, without the capsule flange 27 then sliding off the capsule stop 12.
    [00045] In the next step, illustrated on the basis of figure 1c, the first infusion chamber element 3 is driven by a knee crank lever 28 for a linear displacement along the axial direction 6 towards the second infusion chamber element infusion 4. The orientation of the portion 2 capsule then remains constant with respect to the loading position 10 shown in figures 1a and 1b. The first infusion chamber element 3 is guided by means of a cross pin 35 on a lateral guide rail 16 executed as an elongated hole, the first infusion chamber element 3 in figure 1c initially running along a segment of the guide rail 16 extending exclusively axially. By permanently moving the first infusion chamber element 3 towards the second infusion chamber element 4, then the portion capsule 2 is successively introduced into the hollow compartment of the bell element 21.
    [00046] Based on figure 1d it is illustrated that, just before or during, the capsule bottom touches the second drilling medium 19, the cross pin 35 goes through a displacement 17 on the guide rail 16, with which the first element infusion chamber 3 performs a pivoting movement around a pivot axis 7 (migrating especially along the axial direction 6). The first infusion chamber element 3 is then pivoted to such an extent that the extreme area 8 is aligned parallel to the plane 7 and thus perpendicular to the axial direction 6. The first and second infusion chamber elements 3, 4 are thus aligned essentially parallel to each other. The first piercing means 18 then come into contact with the capsule cap 25.
    [00047] In the next step, represented in figure 1e, by the permanent movement of the first infusion chamber element 3 towards the second infusion chamber element 4, the capsule cap 25 is pierced by the first piercing means 18 executed as tips. drilling. The transverse pin 35 is then guided in a segment of the guide rail 16 extending exclusively parallel to the axial direction 6. The displacement 17 is therefore arranged between two segments of the guide rail 16 extending exclusively along the axial direction 6. The displacement 17 can only be seen in figures 1a, 1b and 1 k, as it is covered by the first infusion chamber element 3 in the other figures. The capsule bottom 29 is not yet perforated at the time shown in figure 1d.
    [00048] In figure 1f the first infusion chamber element 3 is moved to the second infusion element 4 along the axial direction 6 to the withdrawal position 11, so that the portion cap 2 is almost completely inserted into the compartment hollow of the hollow bell element 21 and the capsule bottom 29 is then pierced by the second drilling means 19 performed as a punching mandrel. The first and second infusion chamber elements 3, 4 thus form a hermetically closed infusion chamber 1, in which the portion capsule 2 is arranged. The capsule flange 27 is then firmly secured between the first and second infusion chamber elements 3, 4 especially by means of an elastic sealing ring 36. The capsule stop 12 is then arranged below the second infusion chamber element 4.
    [00049] In this position the extraction operation is started, that is, the infusion chamber 1 'is added to the extraction liquid in the form of active water and heated. The extraction liquid is then transported through the water supply channel 32 to the water outlet openings and passes from there to the portion capsule 2 through the drilling openings produced by the first drilling means 18 in the capsule cap 25. The The drink is then passed through the extraction liquid in a stream, so that a drink extract is formed, which again leaves the portion capsule through the drilling hole produced by means of the puncture mandrel in the capsule bottom 29 and reaches the outlet channel. 24 by the recess 23. By means of the outlet channel 24, the drink extract is preferably added directly to a non-illustrated drinking container, such as a cup of coffee.
    [00050] After the extraction operation, the first infusion chamber element 3 is again moved from the extraction position 11 towards the loading position 10. The extracted portion 2 capsule is then through the retention arms 34 again extracted of the hollow compartment of the bell element 21 and transported towards the loading position. This is illustrated on the basis of figures 1g and 1 h, and during this return movement the transverse pin 35 is again passed through the displacement 17 on the guide rail 16, with which the first infusion chamber element 3 is again brought to an inclined position with respect to the plane 17 and the loading direction 26.
    [00051] By the permanent return of the first infusion chamber element 3, the capsule flange 27, as illustrated in figure 1 i, bumps into a stop area 14 of the capsule ejector 5 facing the second infusion chamber element 4 .
