    [0001] The present invention relates to extraction devices for the preparation of drinks or similar products of an extraction material contained in a capsule, for example, ground coffee. It also covers a sealing system for an extractor device of this type and a scalding module.
    [0002] Extracting devices for the preparation of beverages or similar products from an extraction material contained in a portion package are known, for example, as coffee makers or express machines that enjoy wide acceptance. In many corresponding systems, the packaging of the portions is shaped like capsules in which the product to be extracted is closed airtight. For extraction, normally the capsule or a separate container provided inside the capsule will be perforated on two opposite sides. On the first side, an injection device (introducing device) will introduce an extraction liquid - usually hot water. On the second side, through an extraction device (draining device), the extraction product is drained from the capsule. This happens in a so-called scalding module. A module of this type has a scalding chamber in which the capsule is integrated. A module of this type has a scalding chamber in which the capsule is integrated. The scalding modules in which the capsule is inserted in this scalding module are especially preferred and the scalding chamber will be closed, and in the renewed opening of the scalding chamber, after the scalding process, the capsule is automatically removed from the scalding chamber. and is ejected into a container of capsules. These scalding modules with automatic capsule ejection are often shaped like horizontal scalding modules, that is, the capsule is introduced from above, the closing of the scalding chamber is a relative horizontal movement of two sessions of the scalding chamber , the scalding liquid flows essentially horizontally and the capsule container is shaped below the scalding chamber. Also known are the so-called piston support systems, in which the scalding chamber is formed between an injector and a piston with a rotating lever.
    [0003] When scalding the drink, the extraction liquid is often introduced with a very high pressure, for example, 10-20 bar into the capsule. It is important, in this case, that the extraction liquid passes through the capsule to the second side and does not flow along the capsule due to the high pressure. Therefore, the capsule must be sealed against the injector device and against the extractor device, these seals can be combined.
    [0004] Capsules of conventional devices have a basic conical cup shape with a collar that protrudes laterally. According to a first usual procedure, this collar has an important function in sealing. In the area of the collar, the ring faces a ring-shaped seal, the collar being supported by a counter-element also of an annular shape, in such a way that the collar is stuck between the seal and the counter-element. According to a second usual procedure, the seal is made by a tight seat, the lateral face of the conical cup with a circular cross-section being spatially pressed against a conical face of the same conformation of a slot in the scalding chamber. The cup collar is necessary to secure and position the capsule at the insertion of the capsule in this socket of the scalding chamber.
    [0005] The two procedures were basically approved; however, they only adapt to conical cup-shaped caps mentioned with a collar. This format has the disadvantage that in storage and transport it requires relatively large space and, in addition, the collar, according to the type of material, can be easily damaged when exposed to mechanical stresses.
    [0006] It is the object of the invention to provide an extractor apparatus with a sealing system that does not depend on this form of cup with surrounding collar that adapts to different shapes of capsules and different mechanisms of operation of the scalding chamber and that nevertheless reliably fulfills the sealing function.
    [0007] This task will be solved by the invention as defined in the claims.
    [0008] An extraction device of the species mentioned here is specially designed to scald a drink. It is, for example, a coffee maker. The extractor device has a scalding module to receive a capsule with an extraction material. The scalding module has a first session and a second session of the mobile scalding module in relation to the first session, the first and second session of the scalding module forming a product flow device extracted from the capsule and a device for introducing scalding. a liquid to be extracted inside the capsule, the introducer device having at least one tip for drilling. In addition, the extractor device also has a liquid pump for pumping the liquid to be extracted and eventually heating for the liquid to be extracted before introduction into the capsule. The extraction liquid in many cases is water and when the extractor device is a coffee maker or tea maker, it is also referred to as a "scalding liquid".
    [0009] An extractor device, according to the invention of this type, stands out essentially by the fact that it presents a sealing system with an elastically deformable seal that surrounds the drilling tip, that is, the drilling tips of the introducing device , a sealing collar that positioned the capsule and that surrounds and retains it and at least one surrounding sealing lip and / or a surrounding sealing fillet, leaning in a linear or strip-like manner on a surface of the capsule, pressing on the wall capsule against the inside of the capsule. The fact that the capsule wall is pressed against the inside of the capsule means that at the location of the sealing lip, that is, the sealing fillet, there is no provision for a supporting element, however, that the capsule wall, by the sealing lip, that is, by the sealing fillet, on the contrary it is almost pressed against the capsule load.
    [0010] In this case, the seal is so integrated in the extractor device (especially in its scalding module), that the exact position of the capsule will be determined by the seal itself. Especially, in a different form than occurs in the state of the art, the extractor device is free of a seat that is formed by an especially non-elasticly deformable element, partially surrounding the capsule and leaning spatially on a surrounding wall. In preferred embodiments, it is especially free of non-elastic elements, leaning against the wall of the capsule that touch between an injector plate of the introducer device (plate from which the piercing tips protrude and against which the capsule in the perforation is pressed) and the seal touch up to the capsule.
    [0011] This proposition is based on the perfectly surprising recognition that the pressures necessary to scald a drink, for example, espresso, can be used as a lip seal surrounding this species in order to create the necessary sealing function without being an anvil or a tight seat is required.
    [0012] A seal of this type described is provided for in the introducer device. A seal of this kind on the injection side has the purpose of preventing the scalding liquid to be introduced into the capsule from going through the other way than being pressed into the capsule. On the injection side, the incident pressures are especially intense. The invention is particularly advantageous in combination with injection systems in which, as described in detail in PCT / CH2010 / 000098, the scalding liquid is not injected through a predicted drilling tip with a channel. In these systems, a capsule piercing tip is used instead. The scalding liquid will be introduced into the capsule close to the drill tip and through the opening produced by the drill tip, however, next to the drill tip. In particular, an introduction opening for the scalding liquid can then be located in the plane where the capsule wall abuts. These systems have proven to be completely advantageous in relation to perforation systems and especially in relation to the perforation systems of the capsules more environmentally friendly with a plastic wall. They produce, however, that all the pressure of the scalding liquid touches the sealing system and not, as in the invention, by a tip directly inside the capsule, and a part of the pressure is damped by the extraction product.
    [0013] In a complementary manner, the sealing system preferably also presents, on the side of the drainage device, a seal as described with at least one surrounding sealing lip and / or a surrounding sealing fillet, touching in a linear shape or in strip shape on one face of the capsule, pressing the capsule wall against the inside of the capsule. Preferably, also, a seal on the extraction side has a sealing collar that surrounds the capsule and positions it. A seal of this type on the extraction side involves drilling tips on the extraction side with allocated flow openings, for example, also separated at the location of the drilling bridges and has the purpose of conveying the liquid that leaves the capsule to the expected line and to prevent this liquid from taking another path next to the capsule.
    [0014] The injection side seal and, if necessary, the extraction side seal are attached to the introducer device, that is, the flow device and the movement of the two sections of the scalding module are moved relative to each other (that is, especially, the introducing device in relation to the drainage device) accompanying the seals to movement.
    [0015] The sealing on the injection side and, eventually, also the sealing on the extraction side are produced in an elastic way mainly from an elastomer. For the sealing of the side of the invention, materials with shore hardness between 50 and 90 shoreA were approved, especially between 70 and 85 shoreA as being especially advantageous. The hardness of an extraction side seal can be equal to the injection side seal hardness or it can be less. In particular, the seal on the extraction side can have a hardness between 55 and 80 shoreA.
    [0016] It is often advantageous that the seal is so shaped that at least one sealing side and / or a sealing ring surrounds the capsule along a circumferential face, when due to its elasticity it is pressed against the wall of the capsule in such a way way that the capsule is kept by the seal due to this stop of the sealing sides, that is, of the sealing fillet or of several sealing fillets by the seal.
    [0017] Likewise, depending on the situation it also proved to be advantageous (especially for sealing the side of the invention, but in modalities possibly also for sealing the extraction side) proved to be a constitution that has a variety of surrounding sealing lips and / or sealing fillets, that is, at least two sealing lips, at least one sealing lip and one sealing fillet or at least two sealing fillets. The sealing lips, that is, the sealing fillets, one or more units, by virtue of their elasticity, they press the capsule wall against the interior of the capsule and between sequential sealing lips or fillets a concavity is provided in such a way that in the operational state a hollow compartment is formed between the sealing lips, that is, sequential sealing fillets and the capsule.
    [0018] The surrounding face, in the case of cylindrical or conical circular capsules, is formed by the lateral face, in the case of a square or parallelepiped shape formed by four surrounding sides (which in many modalities differ from the sides through which the scalding liquid and which is drained or the scalded drink from the capsule). A sealing lip, that is, a sealing fillet can touch the capsule wall also at a point where the capsule wall has a non-constant angle in relation to an axis of the capsule or the scalding chamber, for example, at the location of a passage between a front face and the surrounding face.
    [0019] In combination with the proposal to wrap the capsule along a surrounding face, it is especially advantageous for the sealing of the injection side and / or for the sealing of the extraction side that at least one of the sealing lips, that is, surrounding sealing fillets, either pressed against a front face of the capsule and at least against one of the sealing lips, that is, surrounding sealing fillets, against a surrounding face.
    [0020] The scalding chamber of an extractor device, according to the invention, can have several possible shapes, especially circular cylindrical or in the form of a cube (as taught, for example, in the document PCT / CH2010 / 000097). Also not excluded are conical capsules, in the shape of a cup, with or without edge and with or without the arching of one of the frontal faces (a face in which the capsule is perforated), facing inwards.
    [0021] According to one modality, the lip, that is, one of the lips, can extend inward, in the direction of the liquid injection, that is, of the liquid extraction, especially when in the region of a frontal face of the capsule is leaning against it. Then, the pressure of the liquid will press the sealing lip in addition to the effect of its elasticity against the capsule, for example, in the area of the front face.
    [0022] In combination with a sealing collar that surrounds the capsule in a surrounding shape, a sealing lip of this type that protrudes inwards and is intended to touch the front face, it can be protruded inwards from the collar in an area next.
    [0023] A sealing lip of this type that in the region of the frontal face protrudes into the interior will preferably have a cross section of wing or a lobe.
    [0024] It is especially preferred for the sealing of the injection side and / or for the sealing of the extraction side, a conformation of a seal with a lip that protrudes inwards in the area of the front face and a variety of sealing or rounded lips seals with intermediate hollow spaces in the region of the surrounding face and / or in the passage between the frontal face and the surrounding face. This produces a seal in varying degrees which is especially advantageous in the case of injection because the pressure there is more intense and the seal is a special requirement. A lip that protrudes inwards will, in this case, be the first stage that is arranged where there is a high pressure and that due to the conformation of the sealing lip reinforces the sealing action. The lips / fillets in the face region, that is, in the surrounding passage, serve as additional steps, which, together with the intermediate hollow spaces, prevent residual portions of liquids that, for example, during pressure formation or possibly they also passed through the first stage, so they can flow. In addition, they produce a stepped pressure reduction in the event that the first stage does not withstand the full pressure differential between the liquid pressure and the ambient pressure.
    [0025] Especially the sealing on the injection side is preferably shaped in such a way that only on the basis of its elasticity does it keep the capsule wrapped, without additional clamping force, so that the force to extract the capsule from the surrounding seal exceeds the pero specific to the capsule and preferably also when the capsule is completely filled with liquid.
    [0026] As a form of sealing lips in the area of the sealing collar that surrounds the capsule, a conformation like saw teeth in the cross section was especially advantageous for the sealing of the injection side. The shape of this type of sawtooth joins the action of a lip that protrudes inward and that will have pressure applied is reinforced pressed against the capsule, with the clamping action being compared to a lobe-shaped lip that protrudes inwards, presents greater rigidity. This greater rigidity makes it possible to retain the surrounding and reliable capsule.
    [0027] After the scalding process, the scalding chamber will be opened especially by the relative movement of the introducing device and the draining device and the capsule will be ejected, for example, into the capsule container provided for this purpose. An extraction device, according to the invention, according to a group of preferred modalities, is so shaped that a seal that embraces the capsule - especially on the injection side seal - when opening the scalding chamber holds the capsule and makes this way that the capsule is extracted from the opposite drilling beads (especially the extraction side) and possibly from the surrounding seal, provided respectively on the other side (especially the extraction side). In addition, the extractor device has a scraping means whereby after a part of relative movement, the capsule will be retained in relation to the part that moves away (especially the introducer device) with which it will be released from the surrounding seal, for example, fall. The scraping means may, for example, have fillets that are laterally inserted into the scalding chamber and that during the relative movement are displaced inwards or that, due to a round, a comic or other deviation from the mere shape cylindrical capsule only act on the capsule after a part of the relative movement.
    [0028] A scalding system for coffee, tea, in addition to an extractor device described in detail in this text and in the drawings, also features a serving capsule with an extraction product. This portion capsule is especially of the type with a plastic wall that directly surrounds a material to be extracted, that is, without stabilizing intermediate parts or acting as a filter: that is, the capsule consists of the capsule wall and the material to be extracted. An especially preferred material for the capsule wall is polypropylene (PP). Other materials are also imaginable, especially plastics compatible with food products. The wall thickness, especially in the case of polypropylene capsules, will preferably be between 0.1 mm and 0.5 mm, for example, between 0.2 mm and 0.4 mm, especially between 0.25 mm and 0.35 mm. After filling a capsule body with an extracted material, it will be closed by a lid, especially in a process in which together with the solder a protruding edge of the capsule and lid body will be cut. In this way, the capsule has a surrounding weld posture that has a reinforcing effect. The seal, that is, one of the seals can be shaped, with, for example, sealing lips that touch both sides of the weld posture in the capsule.
    [0029] Examples of the invention will be described below based on the drawings. In the drawings, in the same reference months they designate the same or similar elements. The drawings present elements partially corpondentes with each other in different sizes from figure to figure. The figures show:

    [0041] Figures 13 to 15 - views of the scalding module in section along the longitudinal plane, according to figure 1, in different states.
    [0042] The scalding module 1, according to figure 1, is of the "horizontal scalding module" type. It has a known fixation in a structure, that is, it conducts a drainage device 3 and an introducer device 4 that are movable relative to each other by a control lever 5 rotatable around a rotation pin 6. In the designed mode , the introducer device 4 is moved by a rotating movement of the control lever 5 forward, towards the flow device 3, while the latter is immovable with respect to the structure.
    [0043] Figures 1 and 3 clearly show the introduction opening 7 for the introduction of a cubic capsule. An example of a cube-shaped capsule of this type approximately in the shape of a cube, is shown in figure 2. Capsule 51 is of the capsule type as is described in detail in patent application PCP / CH2010 / 000097. The special constitution of a capsule of this type with a plastic device and regarding its production - preferably the capsule will be closed in a process in which simultaneously with the sealing it is cut on the protruding edge - reference is made to patent application PCP / CH2010 / 000097 . In figure 2, beside the characteristic capsule shape, a surrounding 51.1 weld posture that was formed in the mentioned process can also be seen and which can act as an additional reinforcement of the capsule.
    [0044] Extraction device modalities of the invention are specially adjusted by plastic capsules. An especially preferred material in this regard for capsules is PP polypropylene. Other materials can also be imagined, especially other materials compatible with food products. The wall thickness in the conformation as a plastic capsule, especially a polypropylene capsule, will preferably be between 0.1 mm and 0.5 mm, for example, between 0.2 mm and 0.4 mm, especially between 0.25 mm and 0.35 mm.
    [0045] The opening of introduction 7, that is to say, of launching, is shaped in the structure, being in the region of the flow device 3 and remains stationary, like this device, when a control lever 5 moves. the opening opening 7 can be shaped slightly conical and narrowing downwards so that at the introduction, that is, at the launch, it has a centralizing effect on the capsule 51 without the danger of the capsule jamming too great.
    [0046] In the service state, the scalding module serves as precisely a scalding module of a coffee machine. A coffee machine according to the invention with a scalding module has, as schematically shown in figure 3, in addition to the scalding module, a water tank 71, a pump 72 for water supply for scalding up to the introducer device 4 and a water heating device 73 (for example, a passage heater). Below the scalding module is provided a capsule container 75, in which the capsules 51 fall or are transported after the scalding process.
    [0047] The heated water supply to the introducer device 4 is verified through flexible water conducting segments (hoses) and through raceways 18. In addition, the introducer device also has at least one drilling tip 12 with an adductor opening allocated so that the capsule can be pierced and through the adductor opening can be filled with the extraction liquid. The coffee machine also has a container of capsules 75 disposed under the scalding chamber, in which the capsules after the scalding process, by the suspension of the control lever 5, will be automatically ejected.
    [0048] Also a flow device 3 has at least one drilling tip 11 and a corresponding flow opening. In addition, according to the configuration, a flow line is also provided with which the coffee (or similar product) which leaves the outlet 8 of the flow device, will be conducted in such a way that it flows into a cup 78 provided in a location.
    [0049] The drilling tips 11 of the flow device 3 are surrounded by a seal 61 on the extraction side and the drilling tips of the introducer device 4 are surrounded by a seal 62 on the injection side. These seals will be described in more detail below. A scraper element 15 is also being presented whose function will also be described below.
    [0050] The drilling tips and the elements in which they are attached can be conformed according to the mentioned patent application PCT / CH2010 / 000098 in relation to which the explicit reference is made here.
    [0051] With the scalding chamber open (figure 1), the capsule 51 launched in the opening of introduction 7, of approximately cube shape, will be retained in the scalding module by a support session 16 of the draining device 3 and a movable capsule support 19.
    [0052] Figure 4 shows a variant of a scalding module, in which the capsule 51 opened approximately in a cube format, launched into the open scalding chamber, is supported by a support 20 of the scalding chamber that forms together with walls side 14, the end face of the draining device which has the drilling tips 11 of the draining device and elements of the introducing device 4 constituting the scalding chamber. The scalding module according to figure 4 corresponds, except for the sealing system, to the scalding module described in patent application PCT / CH2010 / 000099 and whose teaching is expressly referred to here.
    [0053] Figure 5 shows a device for draining the scalding mode of figure 5 with a capsule 51 schematically presented in section. The seal 61 can be clearly seen and is also shown in figure 6. It has a sealing lip 61.1 that protrudes inwards, surrounding and leaning against the front side of the capsule 51. Along a circumferential face of the capsule it touches a sealing fillet 61.2, as another sealing stage. In the example shown, the seal has an optional external notch 61.3 in the area of sealant fillet 61.2 that increases the elasticity of the seal in the area of sealant seal 61.2. Between the sealing lip and the sealing fillet - that is, in the region of the rounded edge of the capsule - a stamped 61.4 trench is formed which also in the strong compression of the capsule against the flow device forms a hollow space between the sealing lip 61.1, the fillet seal 61.2 and capsule 51. A seal flange 61.5 is for attachment to the scalding module.
    [0054] Another example of executing a seal 61 for the drain device is shown in figures 7 and 8. This seal corresponds to the seal of the drain device 3 of the scalding module according to figure 1. As well as the seal above described, this seal 61 has a sealing collar 61.7 that embraces the capsule 51. In addition to the (first) sealing lip 61.1, next to the sealing collar, projecting in the direction of the interior that, touching the front face of the capsule 51, the sealing 61 has two other sealing lips 61.8 that are in contact with the edge of the capsule. Especially the sealing lips 61.8 appear so far apart, that they are located on both sides of the weld seam 51.1 of reinforcing action, or that it produces an especially good stability and sealing effect.
    [0055] Figures 9 and 10 also present the seal 62 on the injection side of the scalding module according to figure 1. An additional character to the first sealing lip 62.1 leaning against the capsule and projecting inwards, in a collar seal 62.7 a variety of second sealing lips 62.9 is provided. In the execution example presented there are four of these second sealing lips 62.9, and in other modalities, two, three, five or even more (or other) sealing lips are present. Preferably, the number is 2-5, especially 3-5. With the seal 61 on the extraction side, also the injection side seal 62 in the presented mode has a fixing flange 62.5.
    [0056] The second sealing lips, different from the first sealing lip 61.1 and in relation to the other sealing lips 61.8 of the sealing 61 on the extraction side, due to their geometry, present a relatively large stiffness, with which they also exercise a concentrated force without a relatively intense elastic force applied from the outside, keeping it stuck. In the execution example shown, the second sealing lips have a sawtooth shape with a 62.10 lip back that extends in a distant situation (that is, in a direction away from the direction from which the liquid injection is made. scald). This shape also has the effect that the pressure of the scalding liquid from a close position against the approximately perpendicular faces 62.11 presses the sealing lips even more strongly against the capsule wall. Unlike lips, such as the first sealing lips 62.1, which project into the interior and which have a cross section closer to lips in the shape of wings, the sawtooth shape also provides the mentioned stiffness.
    [0057] Figures 11 and 12 also show a seal 61 on the extraction side and a seal 62 on the injection side as they have been used for non-cubic capsules, however, for example, in a cylindrical circular shape, in the shape of a barrel or cup that can be used. In the figures you can clearly see the symmetric rotation format around an axis of capsules, as different from figures 8 and 10.
    [0058] Modalities of the extraction device of the invention are so shaped that the seal 62 on the injection side at the opening of the scalding chamber holds the capsule and extracts it from the piercing tips on the extraction side and the seal 61 surrounding the side of the extraction, so that after use, the capsule falls into the 75 capsule container. This is illustrated in figures 13-15.
    [0059] Figure 1 shows the exit position of the scalding module without the capsule inserted. In figure 13, a capsule 51 has been launched through the introduction opening 7 and rests on the movable capsule support 19 in the resting section 16 and drain device 3. Then, by a movement of the control lever 5, the introducer device 4 will be moved towards the capsule 51 and the flow device 3, with which the seal 62 on the injection side is applied over the capsule and this capsule will be pressed against the flow device and will be perforated both on the injection side and also on the extraction side. In the relative movement that closes the scalding chamber in this way, the capsule support can be removed from the capsule as soon as the capsule is surrounded by the injection side seal and is held in this way. Then, when the scalding chamber is closed, the scalding process takes place, in which the scalding liquid is introduced in a pressurized form into the capsule and the scalded drink will be drained on the extraction side of the capsule.
    [0060] Figure 14 shows the scalding module with capsule 51 at the beginning of the relative movement of the introducing device and the draining device that opens the scalding chamber, which is again produced with a rotating movement of the control lever. The seal 62 on the injection side holds the capsule and pulls it out of the drilling tips 11 on the extraction side and the seal 61 also on the extraction side. In the continuation of the movement in the direction of removal from the position according to figure 14 towards the right side in the direction of the position according to figure 15, the capsule will be captured by the scraper means 15 and its movement in the direction of the introducing device that continues to move will be blocked, with which the capsule will also be extracted from the seal 62 on the injection side. As the support of the capsule 19 has been moved from the exit position, the capsule can then fall into the capsule container 75. Figure 15 shows the situation with the scalding chamber open before the support of the capsule 19 is returned to its initial position. .
    [0061] In the mode shown, the scalding module is of the "horizontal scalding module" type. But other formulas are also possible. Especially the extractor device can also be of the "piston machine" type, in which the flow device and eventually the introducer device are integrated into a piston that can be attached to a fixed part of the extractor device to form the scalding chamber .
