    Descriptive Report of the Invention Patent for CAPSULE OF PORTION AND USE OF A CAPSULE OF PORTION. State of the art [001] The present invention relates to a portion capsule for the production of a drink, having a basic element, in essence, in the form of a cone or cylinder stem, which has a cavity for receiving of a raw material for drink, and a membrane that closes the cavity.
    [002] Capsules of such a portion are generally known. For example, from FR 2 556 323 A1, a portion capsule is known, which has a base element in the form of a cone or cylinder stem, which is used for the production of a drink, with a cavity within the portion capsule is filled with a beverage raw material, in particular, with a coffee powder, and is closed by means of a membrane. For the production of a coffee drink, the serving capsule is arranged in a scalding chamber, in which the membrane is perforated, and an extraction liquid, in particular, hot water is introduced into the cavity. The raw material for the drink is passed through the extraction liquid, in such a way that a drink extract, in particular a coffee drink, is formed. In addition, in the scalding chamber a bottom area of the serving capsule is perforated, such that the beverage extract leaves the serving capsule and, eventually, can reach a beverage container such as a cup of coffee.
    [003] In this portion capsule, the fact that the portion capsule has relatively little mechanical stability is disadvantageous. During the extraction process, the extraction liquid is injected with overpressure into the scalding chamber, such that, during the extraction process, the portion capsule is exposed to a relatively high pressure. So there is a danger that the capsule
    Petition 870190028253, of 03/25/2019, p. 4/27
    2/16 of the portion folds laterally, in particular, in a wall area between the membrane and the bottom area and, thus, the raw material for drink does not pass evenly through the scalding chamber, and / or the extraction liquid flows laterally around the scalding chamber. The taste of the drink to be extracted is therefore considerably affected.
    Disclosure of the invention [004] For this reason it is the task of the present invention to prepare a portion capsule, which does not have the disadvantages of the state of the art and, in addition, which can be manufactured relatively simply and at a low cost.
    [005] The task is solved with a portion capsule for the production of a drink, presenting a basic element, in essence, in the form of a cone or cylinder trunk, which has a cavity for the reception of a raw material for drinking, and a membrane that closes the cavity, with a wall area of the base element having a plurality of grooves.
    [006] In relation to the portion capsule according to the state of the art, the portion capsule according to the invention has the advantage that the wall area of the base element has a higher mechanical stability and, therefore, deformation and, in particular, lateral folding of the portion capsule is prevented. Preferably, a uniform passage of the raw material for drink is ensured in the scalding chamber, so the quality and reliability of the extraction process must increase considerably. In particular, the increase in mechanical stability through the use of the plurality of grooves can lead to the fact that the material thickness of the base element can be reduced in total. The production of the portion capsule, therefore, is considerably more affordable, and beneficial to the environment. On the other hand, in the scalding chamber, due to the plurality of grooves, an adherence of the pa
    Petition 870190028253, of 03/25/2019, p. 5/27
    3/16 netting to the scalding chamber wall is reduced or avoided, so the ejection or removal of the capsule portion of the scalding chamber is favored. Another advantage of the plurality of grooves is that, within the cavity, the current of the extraction liquid is subjected to turbulence along the base area, through the groove structure in the wall area. A stronger turbulence compared to the state of the art of the extraction liquid in the cavity, in relation to the state of the art has the advantage that, no undesired and casual main liquid stream forms through the bed of the beverage raw material, but instead, the raw material for drinking is traversed in its total volume. The extraction process is, therefore, essentially more efficient, and more precise to control or reproduce. Alternatively, it is conceivable that the wall of the capsule has a thickness of material greater than the bottom area, such that the piercing of the portion capsule in the bottom area is simplified. The raw material for drink includes, in particular, coffee powder (preferably roasted and ground coffee), powdered chocolate, powdered milk, tea or similar. Alternatively, it is conceivable that the raw material for drink comprises a beverage extract, such as instant coffee.
    [007] In the sense of the present invention, the grooves are, in particular, cavities or hollows, which preferably have a linear main extension. Most preferably, the grooves are made as webs and / or grooves. In this case, the grooves are optionally made on an internal side facing the cavity, and / or on an external side of the base element, away from the cavity. In a particularly preferred way, it is provided that the grooves extend, respectively, in essence, in a plane parallel to the membrane, the grooves being preferably provided, respectively, circulating around the base element, for example, in form of executed rings circulating around the element of
    Petition 870190028253, of 03/25/2019, p. 6/27
    4/16 base parallel to the membrane and essentially closed.
    [008] According to another object or to a preferred improvement of the present invention, it is envisaged that the membrane will be made rough, at least on an external side away from the cavity. Advantageously, this reduces the adhesion of the membrane to a wall of the scalding chamber facing the membrane, so that an ejection or removal of the capsule portion of the scalding chamber is facilitated after the heating process. extraction. In particular, in a scalding chamber with an automatic ejection mechanism, there is a danger that ejection of the portion capsule does not work reliably, since, after the extraction process, a portion capsule wall or membrane portion capsule adheres to a wall of the scalding chamber. Causes for this can be, for example, electrostatic attraction forces between the portion capsule wall and the scalding chamber wall, and / or corresponding liquid surface stresses between the portion capsule wall and the chamber wall scald. These effects are reduced considerably by structuring the portion capsule wall, for example, through the roughness of the membrane and / or through the arrangement of grooves in the area of the wall, such that, in comparison with the state of the art, it is ensured reliable automatic ejection of the portion capsule out of the scalding chamber. The structuring of the membrane is preferably due to the fact that the membrane is equipped with a rough protective film on the outside. Alternatively, it is conceivable to roughen the membrane, for example, by means of laser irradiation.
    [009] According to another object or a preferred improvement of the present invention, it is provided that a wall area of the base element has a shoulder. Advantageously, the shoulder allows stacking of a plurality of capsules
    Petition 870190028253, of 03/25/2019, p. 7/27
    5/16 portion, for example, before filling the portion capsule. Temporarily before filling the serving capsules with the raw material for drink, the serving capsule has neither raw material for drink nor a membrane. The empty portion capsules and, in particular, the base elements, therefore, can be stacked within one another, whereby a relatively compact space arrangement of a plurality of empty portion capsules is provided. This lowers, in particular, transport costs and storage costs. The portion capsule according to the invention then has a shoulder carried out as a stack edge, whereby two portion capsules stacked together are kept at a distance from each other. In this case, the first portion capsule abuts the shoulder on the other portion capsule. The portion capsule preferably comprises a flange, to which the membrane is attached, the shoulder being carried out, respectively, in particular, adjacent to the flange. Advantageously, the shoulder of the first portion capsule abuts the flange of the other portion capsule. Advantageously, the two flanges of the two portion capsules stacked together are spaced apart from each other corresponding to the height of the shoulder. Advantageously, in order to remove each other from the two portion capsules stacked on each other, each flange must be gripped, in particular, mechanically relatively easily. In addition, due to the spacing of the two portion capsules stacked together, the formation of a vacuum is prevented between the portion capsules, such that the empty portion capsules can be separated from each other again reliably and easily . The portion capsule according to the invention is characterized by the fact that the portion capsule has a flange, to which the membrane is attached, the shoulder being carried out adjacent to the flange. Preferably, in the area of the shoulder, in a plane parallel to the membrane, the base element has a
    Petition 870190028253, of 03/25/2019, p. 8/27
    6/16 increased diameter. Particularly preferably, it is provided that, in the area of the shoulder, the base element is reduced in the direction of the membrane. Advantageously, this effectively prevents the shoulders of two empty portion capsules stacked on one another from sliding into each other. The distance between the two capsules from each other, therefore, is also guaranteed in the case of large axial forces. This is of great importance, for example, when stacking a relatively high number of empty portion capsules. The reduction of the shoulder in the direction of the membrane, in addition, has the advantage that the portion capsule can be secured by means of a retaining or gripping arm in the intermediate area between the flange and the shoulder, for example, in the scalding, during the filling of the scalding chamber or during the manufacture of the portion capsule, the retaining or gripping arm, in this case, being automatically centered between the flange and the shoulder. The bounce therefore has a self-centering effect.
    [0010] According to another object or a preferred improvement of the present invention, it is envisaged that the portion capsule will have a flange, to which the membrane is attached, with an external diameter ratio of the wall area of the element base adjacent to the flange, for the outside diameter of the flange it has a value between 0.79 and 0.95. Advantageously, therefore, compared to the wall area adjacent to the flange, the flange is made relatively large, such that, on the one hand, a sufficiently large adhesion surface on the flange is obtained for the stable fixation of the membrane on the flange, and during the manufacture of the portion capsule, for example, in a deep drawing process, relatively simple centering of the cavity is obtained in the flange area. In particular, the required manufacturing tolerance requirements are reduced in such a way that manufacturing costs
    Petition 870190028253, of 03/25/2019, p. 9/27
    7/16 cation can be lowered in total. On the other hand, in comparison with the wall area, the flange is made small enough so that the lever arm is small between the flange and the wall area. This advantageously leads to the fact that a force effect on the flange does not lead to an undesired deformation of the wall area. Preferably, the ratio of the outer diameter of the wall area of the base element adjacent to the flange to the outer diameter of the flange is between 0.85 and 0.89, and in particular, in essence, is 0.87. Advantageously, an optimized compromise is achieved between large manufacturing tolerances, on the one hand, and low material usage, on the other hand. In addition, an optimized compromise is achieved between good adhesion between the flange and the membrane, on the one hand, and a short mechanical lever arm between the flange and the wall area. It is particularly preferred that the outer diameter of the wall area of the base element adjacent to the flange is essentially 39 mm and / or the outer diameter of the flange is essentially 45 mm.
    [0011] According to another object or a preferred improvement of the present invention, it is envisaged that the base element will have a bottom area that extends, in essence, parallel to the membrane, and a wall area that extends, in essence, between the membrane and the bottom area, the base element in the bottom area covering a material thickness greater than in the wall area. In this way, the base element in the bottom area is advantageously more rigid than in the wall area. This has the advantage that the drilling of the bottom area in the scalding chamber is clearly facilitated, since the bottom area during drilling does not yield or yields only a little in the direction of the cavity. In a preferred improvement of the invention in question, a filter element is provided inside the cavity, which
    Petition 870190028253, of 03/25/2019, p. 10/27
    8/16 divides the cavity into a first area, for the reception of the raw material for drink, and in a second area, for the reception of a drink extract, being that, on one side facing the bottom area of the base element , the filter element is welded to the bottom area. This welding contact is produced, in particular, by means of ultrasonic welding. Advantageously, the production of the weld contact is facilitated by the greater material thickness in the bottom area, since in this case, sufficient material is available in the bottom area for the production of the weld contact.
    [0012] According to another object or a preferred improvement of the present invention, it is provided that, inside the cavity, a filter element is arranged, which divides the cavity in a first area, for the reception of the raw material for drink, and in a second area, for the reception of a drink extract, and on one side facing the bottom area of the base element, the filter element has a melting element. Advantageously, in the area on the side facing the bottom area, the filter element is welded to the bottom area by means of an ultrasonic weld bead. During the production of the weld bead by ultrasound, the melting element is melted by means of ultrasound, such that a weld connection is produced with the bottom area. The solder bond, therefore, is relatively easy to produce. As an alternative to ultrasound welding, it is also conceivable to employ all other known welding processes such as, for example, a friction welding process.
    [0013] According to another object or a preferred improvement of the present invention, it is provided that, inside the cavity, a filter element is arranged, which divides the cavity in a first area, for the reception of the raw material for drink, and in a second area, for the reception of a drink extract, the filter element having at least one surface of re
    Petition 870190028253, of 03/25/2019, p. 11/27
    9/16 tension for gripping the filter element. Advantageously, in the area of the retaining surface the filter element must be gripped in an automated manner, such that, in particular, an automated assembly of the filter element is possible within the base element. With that, the manufacturing costs for the portion capsule can be lowered.
    [0014] According to a preferred improvement, it is provided that the filter element has a plurality of filter openings, the filter openings being arranged outside the retaining surface, and particularly preferably the retaining surface is formed in a central area of the filter element. Advantageously, therefore, it is possible to grasp the filter element with a suction head, which keeps the filter element in the area of the retaining surface by means of a vacuum, without the vacuum being compensated by an air supply through the filter openings. Preferably, the suction head is attached to a mobile mounting robot arm in all spatial directions.
    [0015] According to another object or a preferred improvement of the present invention, it is provided that, inside the cavity, a filter element is arranged, which divides the cavity in a first area, for the reception of the raw material for drink, and in a second area, for the reception of a drink extract, the portion capsule having a relationship between a first gap between the membrane and the filter element, for a second gap between the bottom area of the filter element. base and filter element between 3.5 and 4.5. Preferably, the ratio of the first interval to the second interval is between 3.8 and 4.2 and, preferably, in essence, is 4. Particularly preferred, the first interval is, in essence, 20 millimeters and the second range is, in essence, 5 millimeters. Advantageously, a relationship is obtained
    Petition 870190028253, of 03/25/2019, p. 12/27
    10/16 optimized between the volume of the first area and the volume of the second area, in order to extract a certain amount of raw material for drink disposed in the first area, and during the extraction process take in alternating effect with a certain amount of air, which is in the second area. In a particularly advantageous manner, in this way, in particular, a coffee drink with an ideal aroma and an ideal cream is produced. At the same time, the portion capsule can be manufactured in the most compact space possible and, therefore, at low cost.
    [0016] According to another object or a preferred improvement of the present invention, a filter element is provided within the cavity, which divides the cavity into a first area, for receiving the raw material for drink, and in a second area, for receiving a drink extract, the filter element having a continuous sealing lip, for sealing the first area in relation to the second area, which fits with closure due to the shape of the wall area of the base element, and extends perpendicular to the membrane, at least, across the entire height of the filter element. Advantageously, the second area is sealed in relation to the first area through the sealing lip, in such a way that no extraction liquid can pass through the filter openings of the first area to the second area. This is necessary so that no raw material for drink can reach the second area, and from there for the drink. The sealing lip is self-sealing in such a way that an increase in pressure in the first area causes an enhanced compression of the sealing lip in the wall area, that is, the sealing effect increases with the pressure to be sealed. Advantageously, this effect is particularly strong when the sealing lip extends beyond the filter surface of the filter element, provided with the filter openings, in the direction of the membrane. The sealing lip is made, in particular, in a circular shape in a plane
    Petition 870190028253, of 03/25/2019, p. 13/27
    11/16 parallel to the membrane, the diameter of the sealing lip being preferably reduced towards the bottom area of the base element.
    [0017] Another object of the present invention is the use of a portion capsule according to the invention for the production of a hot drink.
    [0018] Examples of execution of the present invention are represented in the figures, and will be explained in detail in the description below. The figures are described by way of example only, and do not restrict the general idea of the invention.
    [0019] Figures 1,2 and 3 show schematic side views of a portion capsule according to a first, second and third embodiment of the invention in question.

    [0023] In the various figures, the equal parts are always provided with the same reference numbers and, for this reason, as a rule, they are also indicated or mentioned only once.
    [0024] In figure 1 there is shown a schematic side sectional view of a capsule of portion 1 according to a first embodiment of the invention in question, with the capsule of portion 1 having a basic element 2, cone-shaped, which is shaped like a pot, and involves a cavity 3. Cavity 3 is closed by a membrane 4. The base element 2
    Petition 870190028253, of 03/25/2019, p. 14/27
    12/16 comprises, in particular, a soft, semi-rigid or rigid plastic material, which has preferably been deeply drawn. The membrane 4 preferably comprises a thin plastic or aluminum film. The base element 2 has, in the area of the membrane 4, a surrounding fixing flange 7, the membrane 4 being connected, in particular, welded or glued with the fixing flange 7 with closure due to the material. A filter element 5 is arranged within the base element 2, which is made of a thermoplastic plastic, for example, polypropylene. The filter element 5 divides the cavity 3 into a first area 8 and a second area 9. The first area 8 is foreseen for receiving a raw material for drink, which is not illustrated in the figures for the sake of clarity. For example, the first area is filled with a coffee powder, before the cavity 3 is closed by the membrane 4. The coffee powder during filling in the first area 8 is preferably well compressed. The second area 9 serves for the reception and, in particular, for the collection of a drink extract, not shown, during the extraction process of the portion 1 capsule. The portion 1 capsule is intended to be inserted in a scalding 10 from a coffee machine not shown, in which to the first area 8 an extraction liquid (for example, hot water) is carried, preferably under high pressure. This extraction liquid interacts with the raw material for drinking, in such a way that a drink extract is formed. On a filter surface 5 ', the filter element 5 has a plurality of filter openings 13, not shown in figures 1, 2 and 3, and therefore functions as a filter for the beverage extract. In this case, the drink extract is able to reach, through the filter openings 13, in the second area 9. The second area is limited by a bottom area 11 of the base element 2, which is perforated in the scalding chamber 10, for example , by means of a pin for drilling the bottom 21 of the coffee machine, in order to produce an outlet opening for the beverage extract. Alternatively, it is conceivable that in the area
    Petition 870190028253, of 03/25/2019, p. 15/27
    13/16 bottom 11 under the pressure of the extraction liquid automatically if an outlet opening is formed and / or an outlet opening or an outlet valve is already integrated in the bottom area 11. The cross section of the filter openings 13 is chosen in such a way that, in essence, no particle of the beverage raw material can pass from the first to the second area 8, 9. So that the filter element 5 does not perform any relative displacement to the base element 2, the portion capsule 1 optionally has an ultrasound solder connection 6 to the base element 2. The membrane 4 is made rough on one side away from the cavity 3, so that after the extraction process an adhesion between the membrane 4 and a wall of the scalding chamber 10 is avoided or reduced and, thus, a flawless automatic ejection of the portion capsule 1 is obtained out of the scalding chamber 10. In addition, the base element 2 presents a wall area 12, which extends, in essence, between the flange 7 and the bottom area 11. In the wall area 12 a plurality of grooves 15 are made, which are made in the wall area 12 and are executed in form that of grooves, in essence, surrounding, facing the cavity 3. The grooves 15 could be executed in the direction of the circumference also partially interrupted. In addition, the grooves 15 are made in such a way that the wall area 12 is reinforced or hardened through the plurality of grooves 15. Furthermore, due to the plurality of grooves 15, which are arranged distributed, in particular, across the area wall 12, adhesion between the wall area 12 and the wall of the scalding chamber 10 is prevented after the extraction process, so an automatic ejection of the portion 1 capsule out of the scalding chamber is facilitated. The capsule of portion 1 illustrated in figure 1 further comprises a continuous shoulder 16, which is performed in an intermediate area between the wall area 12 and the flange 7, and which in relation to the wall area 12 has an increased diameter (parallel to the membrane 4). The con
    Petition 870190028253, of 03/25/2019, p. 16/27
    14/16 the shoulder 16 is preferably made in such a way that the diameter of the shoulder 16 remains constant in the direction of the flange 7, as shown in figure 1, or as shown in figure 3, it is reduced again in the direction of the flange 7. The bottom area 11 has an increased material thickness compared to the wall area 12, in order, for example, to favor the drilling of the bottom area 11 and the production of the ultrasonic weld connection 6. On the side facing the bottom area 11 the filter element 5 has a melting element 17, which during an ultrasound welding process, for the production of the ultrasound welding connection 6, is at least partially cast over the bottom area 11 The filter element 5 has, for example, a reinforcement structure 5 ', which supports the filter surface 5' on the side facing the second area 9. In addition, the filter element 5 has a continuous sealing lip 18 , which in proximity bottom area 11, is connected with the remaining filter element 5, and from there protrudes in the direction of the flange 7. The sealing lip 18 is made at least partially flexible and extends beyond the filter surface 5 'in the direction 7 of the flange 7. The free end of the sealing lip 15 is engaged in a groove 15 inserted in the wall area 12, and fits into the wall area 12 with closure due to the shape, such that an additional seal is obtained between the first and the second area 8, 9, which prevents flow around the filter element 5. In this case, the sealing lip 18 is made in such a way that it presents a compression surface 18 'facing the first area 8. An increase in pressure in the first area, for example, through the inflow of the extraction liquid in cavity 3, now leads to a force effect on the compression surface 18 'in the direction of the wall area 12, in such a way that the sealing effect the area is increased between the wall 12 and the sealing lip 18 depending on the pressure in the first tract 8. A first gap along a line perpendicular to the membrane 4 between the membrane 4
    Petition 870190028253, of 03/25/2019, p. 17/27
    15/16 and the filter surface 5 'facing the membrane 4 preferably covers, in essence, 20 millimeters, while the second gap along a line perpendicular to the membrane 4, between the filter surface 5' facing the membrane 4 and the bottom area 11 are preferably, in essence, 5 millimeters.
    [0025] In figure 2 is shown a schematic side section view of a portion 1 capsule according to a second embodiment of the invention in question, the second embodiment being essentially similar to the first of execution illustrated in figure 1, the portion capsule 1 according to the second embodiment having no shoulder 7, no sealing lip 18, and no increased material thickness compared to the wall area 12 in the bottom area 11. In addition, the grooves 15 are made as grooves made on the side of the wall area 12, away from the cavity 3.
    [0026] In figure 3 there is shown a schematic side section view of a portion 1 capsule according to a third embodiment of the invention in question, the third embodiment being essentially similar to the first form of execution illustrated in figure 1, with the portion 1 capsule according to the third embodiment having only two grooves 16 in the wall area 12, and one of the grooves 15 serves, at the same time, to hold the filter element 5.
    [0027] In figure 4 is shown a schematic perspective view of a 1 portion capsule according to a fourth embodiment of the invention in question, the fourth embodiment being essentially similar to the second embodiment execution illustrated in figure 2, and in the wall area 12 three grooves 16 are formed.
    [0028] Figure 5 shows a schematic view of a filter element 5 according to a fifth embodiment of
    Petition 870190028253, of 03/25/2019, p. 18/27
    16/16 invention in question, with the fifth embodiment essentially resembling the second embodiment illustrated in figure 2, and in figure 5 the filter surface 5 'is reproduced from the perspective of the membrane 4 The filter openings 13, in this case, are arranged in such a way that, in the central area of the filter surface 5 'there are no filter openings 13. Furthermore, the filter surface 5' is made flat in the central area . Therefore, in the central area, the filter element 5 has a retaining surface 14, which is provided for gripping the filter element 5 by means of a vacuum suction head.
    [0029] In figure 6 is shown a schematic perspective view of a plurality of capsules of portion 1 stacked according to a sixth form of execution, the sixth form of execution being essentially similar to the fourth form of execution illustrated in figure 4, and the portion 1 capsule according to a sixth embodiment, in addition, has a shoulder 16, which is not yet filled with a raw material for drink, still does not have any filter element 5, and it is not yet closed with a membrane 4. In figure 11, six empty portion 1 capsules of this type are reproduced in total, five of the portion 1 capsules are already stacked inside one another. In this case, a capsule of portion 1 is always with its shoulder 16 on the flange 7 of a capsule of portion 1 that is below, in figure 6 those five capsules of portion 1 already stacked inside one another are stacked along one direction stack 101 in a sixth 1-serving capsule.
