Description

Capsule and beverage system for making a beverage

The invention relates to a capsule and a beverage system for producing a beverage. In a capsule-based beverage system, the ingredients of a capsule introduced into the beverage system may be mixed with another liquid (e.g., water) to provide a serving of a beverage. For the reliable production of mixed drinks, it is typically necessary for the contents of a capsule to be transferred as completely as possible from the capsule into the mixed beverage. Furthermore, contamination of the beverage system with ingredients from a capsule should be avoided in the production of a mixed beverage, in particular in order to use the beverage system in a cost-efficient manner for the production of different mixed drinks. The present document addresses the technical problem of providing a capsule and a beverage system that enables reliable and cost-effective production of complex mixed drinks.

The object is solved by the subject matter of the independent patent claims. Advantageous embodiments are defined in particular in the dependent claims, described in the following description or illustrated in the accompanying drawing.

According to one aspect of the invention, a capsule, in particular a multi-chamber capsule, for producing a beverage is described. The capsule may contain the ingredients for exactly one serving (eg for a glass) of a (alcoholic or non-alcoholic) beverage. For the preparation of a beverage, the contents of a capsule may be substantially completely removed from the one or more chambers of the capsule. The capsule thus typically contains substantially no ingredients after preparation of a beverage. The capsule comprises a capsule body which is at least partially covered on an upper side of the capsule with a lid (in particular with a sealing foil). The capsule body and the lid enclose a first chamber for receiving a first ingredient and optionally a second chamber for receiving a second ingredient. The separate storage of different ingredients (especially different liquids) in different chambers allows increased durability of a capsule.

The capsule further includes a chamber wall enclosing a channel-shaped cavity extending from the top of the capsule to an underside of the capsule. The upper side of the capsule typically corresponds to the side of the capsule which points upwards in a beverage system during the production of a beverage. On the other hand, the bottom of the capsule in a beverage system typically faces downward during the production of a beverage. Thus, during production of the beverage (possibly alone), the contents of a chamber of the capsule may be conveyed by gravity to the bottom of the capsule and thus out of the capsule.

The chamber wall adjoins the first chamber and possibly the second chamber. In particular, the chamber wall may form a wall of the first chamber in a first subregion and possibly a wall of the second chamber in a second subregion. The chamber wall may e.g. be formed as a tube extending from the top of the capsule to the bottom of the capsule. In this case, the channel-shaped cavity can be arranged within the tube formed by the chamber wall. The tube and / or the channel-shaped cavity preferably have a substantially circular cross-section. Furthermore, the tube formed by the chamber wall preferably extends substantially centrally through the capsule.

Thus, a channel-shaped cavity may be provided through the capsule through which liquids from a beverage system and / or the ingredients from the one or more chambers of the capsule may be conveyed into a beverage. The channel-shaped cavity may in an initial state of the capsule at the top and / or at the bottom of the capsule with a sealing foil (eg as part of the lid of the Chamber) be closed. Thus, the channel-shaped cavity can be protected from contamination.

The capsule further comprises a valve means with which a first outlet opening of the first chamber and possibly a second outlet opening of the second chamber can be opened on the chamber wall by means of a rod introduced into the cavity from the top of the capsule (in particular by means of an inserted lance), so that the ingredients from the chambers can flow out of the capsule via the cavity at the bottom of the capsule. Thus, there is described a capsule having a (central) channel-shaped cavity which can be efficiently used as an outlet channel of the capsule. The valve means of the capsule makes it possible to open the one or more outlet openings of the capsule, without causing contact between the contents of the capsule and a beverage system. In particular, the one or more outlet openings can be opened by a bar of a beverage system without the rod coming into contact with the contents of the capsule. Thus, contamination of a beverage system by the contents of a capsule can be reliably avoided.

The chamber wall may form the valve housing of a valve of the capsule, wherein the first outlet opening and possibly the second outlet opening may be formed as openings in the valve housing. The valve means may then form a closure part of the valve of the capsule. In this case, the closure part may comprise a (cylindrical and / or cone-shaped) closure part wall which encloses the channel-shaped cavity. Furthermore, the closure member may include one or more apertures in the closure member wall which may be aligned with the one or more outlet openings by movement of the closure member relative to the valve housing to open the one or more outlet openings. Thus, a capsule can be provided with a valve. By moving the closure member of the valve, the capsule can be opened and closed again in an efficient and reliable manner (in particular without causing contact between the contents of the capsule and a beverage system). The one or more apertures in the closure member wall may be arranged such that the one or more apertures in the closure member wall can be aligned with the one or more exit orifices by translational movement of the closure member toward the bottom of the capsule to open the one or more exit orifices , Alternatively or additionally, the one or more apertures may be disposed in the closure member wall such that the one or more apertures in the closure member wall can be removed from the one or more apertures by translational movement of the closure member toward the top of the capsule Close the outlet openings. Alternatively or additionally, the one or more apertures may be disposed in the closure member wall such that the one or more apertures in the closure member wall may be aligned with the one or more exit apertures by rotational movement of the closure member to open the one or more exit apertures and / or or can be removed from the one or more outlet openings to close the one or more outlet openings. It can thus be provided a translational and / or rotary valve to open the capsule in an efficient and reliable manner and possibly reseal.

The valve of the capsule formed by the valve housing and the closure part can be designed such that a movement of the closure part can change an opening degree of the first outlet opening in order to change a volume flow of the first ingredient from the first chamber into the channel-shaped cavity. Alternatively or additionally, the first outlet opening and the second outlet opening may have different shapes and / or geometries, such that a movement of the closure part can change a ratio of the volume flows of the first ingredient and the second ingredient from that of the respective chamber into the channel-shaped cavity. The capsule can thus be designed to flexibly adapt the volume flow of the contents of the capsule. Thus, the quality of a manufactured drink can be increased. The one or more outlet openings may be arranged in a lower region of the valve housing, wherein the lower region of the underside faces the capsule. The valve housing may also be in an upper region, which faces the top of the capsule, as a breakthrough through the valve housing have formed first inlet opening to the first chamber. The first inlet port may be used to convey a flushing medium (eg, a gas and / or a liquid) into the first chamber to convey the first ingredients from the first chamber with the assistance of the flushing medium. Thus, the removal of the ingredients from the one or more chambers of a capsule can be improved.

The closure member may include an aperture in the closure member wall which may be aligned with the first inlet aperture by movement of the closure member relative to the valve housing to open the first inlet aperture. In this case, the valve of the capsule formed by the valve housing and the closure part can be designed such that the one or more outlet openings and the first inlet opening can be jointly closed or jointly opened by a movement of the closure part. Thus, a removal of ingredients from the capsule can be made possible in a reliable manner. The closure member may comprise contact means for allowing a rod (a beverage system) inserted from the top of the capsule to act on the closure member to move the closure member, in particular to urge the closure member toward the bottom of the capsule, to the top of the capsule Pull capsule and / or rotate relative to the valve body. By providing a contact means on the closure part, a reliable movement of the closure part for opening and / or closing a capsule can be made possible. Furthermore, if necessary, an opening degree of the one or more outlet openings can be changed in a precise manner. The contact means may comprise a rib disposed on an inner side of the closure member wall, which is formed such that a shoulder of a rod (a beverage system) can act on the rib to move the closure member, in particular around the closure member towards the bottom of the capsule to press. This allows an efficient and reliable opening of a capsule.

The rib extending along the inside of the closure member wall may have one or more breaks. The rib with the one or more interruptions can be designed such that by the one or more Interruptions corresponding one or more wings of a bar (a beverage system) can be performed when the rod is moved in a first rotational position from the top of the capsule into the cavity. Furthermore, the rib may be formed with the one or more interruptions such that the one or more wings may act on the rib of the closure member to pull the closure member toward the top of the capsule when the rod is in a second rotational position relative to the capsule Top of the capsule is moved. By providing a fin with one or more breaks, it is possible to efficiently and reliably close a capsule. The valve of the capsule formed by the valve housing and the closure member may comprise one or more sealing elements (in particular sealing rings) adapted to seal a gap between the valve housing and the closure member, both when the one or more outlet openings are closed and when the one or more several outlet openings are open. In this case, the intermediate space can in particular be sealed in such a way that substantially no ingredients can pass from the one or more chambers into the intermediate space. Thus, contamination of a beverage system by the contents of a capsule can be reliably avoided. As already stated above, the closure part can be designed to close the one or more outlet openings after opening. By sealing a capsule following the production of a beverage, the contamination of a beverage system by the contents of a capsule can be reliably avoided.

The closure part of the valve may at least partially consist of a different material than the valve housing. For example, closure member made of PET and the valve housing made of PE (or vice versa) exist. Thus, even after a longer storage time of a capsule, a reliable opening and / or closing of the valve can be ensured.

Alternatively or in addition to the function of the valve housing of a valve, the chamber wall may comprise a first flap for the first chamber. Furthermore, the Chamber wall have one or more further flaps for one or more other chambers. Furthermore, the valve means may comprise a first predetermined breaking point, wherein the predetermined breaking point is adapted to be broken by a rod inserted into the cavity from the top of the capsule to open the first flap and thus the first outlet opening. For example, a rib may be arranged as a valve means on the chamber wall. The rib on the chamber wall may make it possible to exert a force on the first flap by means of a rod from the outside. By this force, the first flap can be torn or broken. In this case, the first flap can be opened such that the first flap can not be fully closed again. On the other hand, the first flap (for example, by the choice of a suitable elastic material) may be formed such that the first flap at least partially reseals the first outlet opening when no external force acts on the first flap. Thus, a cost effective "valve mechanism" for a beverage capsule may be provided The capsule may include at the bottom of the capsule a nozzle configured to concentrate and / or focus a flow of liquid from the channel shaped cavity The first chamber may have a greater capacity than the second chamber, or alternatively, the bottom of the first chamber may be closer to the bottom of the capsule than the bottom of the second Chamber.

The capsule body may be asymmetrical, in particular asymmetrical with respect to rotation about an axis of rotation along the channel-shaped cavity, such that the capsule allows for unambiguous orientation of the capsule, in particular with respect to rotation about the axis of rotation. Thus it can be achieved that the capsule can be inserted in a unique position in a capsule carrier of a beverage system. As a result, errors in the operation of a beverage system can be reduced.

As already stated above, the channel-shaped cavity can be enclosed directly by a wall. In particular, the channel-shaped cavity of a capsule the closure part wall of a closure part of a valve of a capsule are formed. The wall of the channel-shaped cavity may have on an inner side a profile (in particular a spiral-shaped profile) which is designed such that an angular momentum is displaced by the profile from the liquid jet flowing from the upper side of the capsule to the lower side of the capsule. In this case, the profile can in particular be designed such that a Coriolis force is amplified by the profile onto the liquid flowing through the channel-shaped cavity. In this case, the liquid may be pumped by a pump from the top of the capsule forth in the kanalformigen cavity (with a certain pressure). The profile can be formed by indentations and / or elevations on the inside of the wall of the channel-shaped cavity. By providing a profile, the liquid jet emerging at the bottom of the capsule can be bundled. Thus, the quality of the drinks produced can be increased. Furthermore, such a contamination of a beverage system can be avoided. The (additional) liquid flowing through the channel-shaped cavity may have carbonic acid and / or be carbonated. In particular, a carbonated liquid can be introduced into the channel-shaped cavity by a beverage system (in particular by a hollow bar of a beverage system). The (additional) liquid may include, for example, water and / or alcohol. Due to temperature changes of the liquid in the capsule and / or in the beverage system, gas, in particular carbon dioxide, may possibly escape from the liquid. The channel-shaped cavity may be formed such that a cross-section of the channel-shaped cavity widens toward the underside of the capsule. Thus, a pressure release of the liquid can be effected in the channel-shaped cavity. Furthermore, it is thus possible to support the escape of free gas from a liquid jet. Alternatively or additionally, a lower edge of the capsule facing the lower edge of the kanalformigen cavity directly enclosing wall (in particular the closure member wall) comprise one or more recesses, can escape through the gas from the channel-shaped cavity. The channel-shaped cavity can thus be designed such that gas, which emerges from a liquid in the channel-shaped cavity, can be reliably removed from the channel-shaped cavity. Thus, the reliability of the production of a (carbonated) drink and / or the quality of a be increased. Furthermore, such a contamination of a beverage system can be reliably avoided.

The second outlet opening of the second chamber may be located closer to the top of the capsule than the first outlet opening of the first chamber. In particular, the outlet openings may be arranged such that first of the second chamber exiting second ingredients and then emerging from the first chamber first ingredients with a flowing from the top to the bottom of the capsule through the channel-shaped cavity (additional) liquid mix. The second ingredients may have a higher solubility in the liquid flowing through the channel-shaped cavity than the first ingredients. By sequentially adding different ingredients to the liquid flowing through the channel-shaped cavity, the quality of a prepared mixed beverage can be increased, especially if ingredients having a relatively high solubility and only then ingredients having a relatively low solubility with the liquid flowing through the channel-shaped cavity Liquid are mixed.

According to one aspect of the invention, a beverage system for producing a beverage, in particular a mixed beverage, based on ingredients of a capsule is described. In particular, a capsule may be processed by the beverage system which comprises ingredients for exactly one portion (for example a glass) of a (alcoholic or non-alcoholic) beverage. From the (in particular substantially all) ingredients of a capsule, a portion of a beverage can be made by the beverage system.

The beverage system typically includes a housing that at least partially encloses an interior of the beverage system. For example, the housing may be cuboid, with four side walls, a floor and a ceiling wall. The beverage system can be designed, for example, as a domestic appliance, in particular as a household appliance, which can be placed on a worktop of a kitchen and / or installed in a built-in cupboard, for example. The beverage system may be configured to receive a capsule described in this document. The beverage system comprises a capsule carrier for receiving a capsule. Furthermore, the beverage system comprises an output unit for providing a beverage based on the ingredients of the capsule. In addition, the beverage system includes an opening means adapted to open the one or more outlet openings of the capsule received by the capsule carrier so that ingredients on the underside of the capsule can flow from the channel-shaped cavity of the capsule to the dispensing unit. In this case, the capsule and in particular the channel-shaped cavity can be arranged directly above the dispensing unit, so that the ingredients from the capsule and / or liquids from the beverage system can flow directly from the channel-shaped cavity to the dispensing unit (eg into a cup on the dispensing unit).

The opening means may comprise a rod adapted to be moved from the top of the capsule carrier received capsule into the cavity of the capsule to open and / or close the one or more outlet openings of the capsule. The rod can be designed as a hollow rod with a liquid channel. The beverage system may then be configured to provide a liquid (e.g., water and / or alcohol) for the beverage at an upper side of the liquid channel so that the liquid flows through the liquid channel to the channel-shaped cavity of the capsule and thence to the dispensing unit. By using a hollow bar, a beverage can be efficiently and reliably bundled over the channel-shaped cavity of the capsule. Thus, good mixing of the liquid and the capsule ingredients to produce a high quality beverage can be ensured.

The rod may comprise an at least partially extending around the rod paragraph, which is adapted to press on a rib of a closure part of the capsule to move the closure member towards the bottom of the capsule and thereby to open the one or more outlet openings of the capsule ,

In this case, the shoulder can be designed to make the channel-shaped cavity fluid-tight above the rib of the closure part, so that a sealed cavity is formed above the shoulder. The beverage system can then be set up over the sealed cavity and a first inlet opening of the first chamber of the capsule to convey a flushing medium (eg, a gas and / or a liquid) in the first chamber. Thus, the contents of the first chamber of a capsule can be completely and quickly conveyed out of the capsule. The rod may comprise, on a side of the shoulder facing the capsule, one or more vanes adapted to be guided in a first rotational position of the rod by corresponding one or more interruptions of the rib of the closure member and in a second rotational position upon movement of the rod towards the top of the capsule, the rib may act to pull the closure member toward the top of the capsule. Between the first rotational position and the second rotational position, a rotation of the rod (for example, a rotation between more than 0 ° and 90 °) can take place.

The beverage system may thus be adapted, in the context of the production of a beverage, to move the rod in the first rotational position in the direction of the underside of the capsule in order to press through the shoulder the closure part in the direction of the underside of the capsule, thereby forming the one or more outlet openings to open the capsule. It can then be the ingredients from the capsule are transferred to the drink. Furthermore, the drink system may be arranged to move the rod in the second rotational position in the direction of the top of the capsule in the context of the production of a beverage in order to pull the closure member towards the top of the capsule by means of the one or more wings to close one or more outlet openings of the capsule. By sealing the capsule following the production of a beverage, contamination of the beverage system can be reliably avoided.

The rod may comprise on a side facing the capsule a needle which is adapted to pierce a lid and / or a sealing foil covering the channel-shaped cavity. The rod can thus be designed as a lance.

It should be noted that any aspects of the system described in this document and the capsule described in this document are interrelated in a variety of ways can be combined. In particular, the features of the claims can be combined in a variety of ways.

Furthermore, the invention will be described with reference to embodiments illustrated in the accompanying drawings. Show

As stated above, the present document is concerned with the reliable production of a beverage based on the ingredients of a capsule.

In this context, Fig. 1a shows an exemplary capsule, in particular an exemplary multi-chamber capsule 100. The capsule 100 shown in Fig. 1a comprises two chambers 1 10, 120, wherein the chambers 1 10, 120 by separate shells or Vessels are formed. The chambers 1 10, 120 can be used to keep different ingredients separate from each other. By providing a plurality of chambers 1 10, 120 for different ingredients, the shelf life of the ingredients of a capsule 100 can be increased. The capsule 100 can be used in a beverage system or a vending machine for the production of mixed drinks. In this case, alcoholic and / or non-alcoholic drinks can be produced. The preparation of a portion of a beverage may be accomplished by bringing the ingredients (eg, liquids) stored within a capsule 100 into contact with a liquid stream provided by the beverage system. In this case, if possible contamination of the beverage system by ingredients from a capsule 100 should be avoided in order to use the beverage system in an efficient and comfortable way for the production of a variety of portions of possibly different types of drinks can. The capsule 100 shown in Fig. 1 a comprises a capsule body 101, through which the one or more chambers 1 10, 120 of the capsule 100 are formed. The capsule body 101 may be covered by a lid 102, wherein the lid 102 may be formed by a sealing foil. Furthermore, the capsule 100 comprises a valve 130, 140, wherein the valve 130, 140 comprises a valve housing 140 (also commonly referred to as a chamber wall) in which a closure member 130 is disposed. The valve housing 140 may be part of the capsule body 101 and may at least partially form the one or more chambers 1 10, 120. In particular, the valve housing 140 may each form at least one wall of the one or more chambers 1 10, 120. The closure member 130 may be moved within the valve housing 140 to open and close the valve 130, 140, respectively.

In the example shown in FIG. 1, the valve housing 140 encloses a (circular) cylindrical space in which the closure part 130 can be moved translationally in order to open or close the valve 130, 140. Specifically, the valve 130, 140 may be opened when the shutter member 130 is moved downwardly, and closed when the shutter member 130 is moved upward. The valve housing 140 has, in an upper region or near an upper side of the capsule 100, a first inlet opening 11 1 1 for the first chamber 110 and a second inlet opening 121 for the second chamber 120. An inlet opening 1 1 1, 1 12 can be used to a chamber 1 10, 120 supply a flushing medium to flush the ingredients from the chamber 1 10, 120 out. Alternatively or additionally, an inlet opening 1 12, 1 12 can be used to ventilate a chamber 1 10, 120 to allow (possibly caused solely by the gravitational force) leakage of the contents of a chamber 1 10, 120.

Furthermore, the valve housing 140 in a lower region or near an underside of the capsule 100 on a first outlet opening 1 12 for the first chamber 1 10 and a second outlet opening 122 for the second chamber 120. About an outlet opening 1 12, 1 12, the ingredients of a chamber 1 10, 120 from the chamber 1 10, 120 expire. The closure part 130 may be configured to close the openings 11 1, 12, 121, 122 of the one or more chambers 110, 120 in a closed state of the valve 130, 140. On the other hand, the openings 1 1 1, 1 12, 121, 122 can be opened by a movement of the closure part 130, so that the ingredients from the one or more chambers 1 10, 120 may leak (possibly using a flushing medium, the one or more chambers 1 10, 120 can be supplied via the one or more inlet openings 1 12, 1 12). For this purpose, the closure part 130 may have a first opening 134 for opening the first chamber 110 and optionally a second opening 136 for opening the second chamber 120. The one or more apertures 134, 136 (the closure member wall) of the closure member 130 may be brought by a movement of the closure member 130 in front of the outlet openings 1 12, 122 of the valve housing 140, so that one or more outlet channels of the one or more chambers 1 10, 120 through the outlet openings 1 12, 122 and openings 134, 136 in a channel-shaped cavity of the closure part 130 is provided.

The closure member 130 may have a (cylindrical) channel extending from an upper end 131 of the closure member 130 to a lower end 132 of the closure member 130. The cavity is thereby through the Closing part wall of the closure part 130 enclosed, wherein the openings 134, 136 are formed by openings in the closure part wall of the closure part 130. The cavity of the closure member 130 may be positioned within a beverage system over a container for a beverage such that the ingredients flowing out of a chamber 110, 120 may flow directly from the channel shaped cavity into the container without contacting a component of the beverage system come. It can thus be avoided in an efficient and reliable way contaminations of a beverage system.

Fig. 1 b shows the capsule 100 of Fig. 1 a in an open state. In particular, FIG. 1 b shows how, by a movement 150 of the closure part 130, an opening 134, 136 of the closure part 130 can be moved in front of an outlet opening 12, 122 of a chamber 110, 120. Furthermore, Fig. 1 b as well as a passage 133, 135 of the closure member 130 in front of an inlet opening 1 1 1, 121 a chamber 1 10, 120 can be moved. Thus, the ingredients may be caused to flow out of the capsule 100 from one or more chambers 110, 120 via the channel-shaped cavity of the closure member 130. Possibly. can be passed through an opening 133, 135 of the closure member 130 and an inlet opening 1 1 1, 121 a chamber 1 10, 120 a flushing medium into the chamber 1 10, 120 to rinse out the ingredients from the chamber 1 10, 120 out ,

FIG. 1 c shows a detail of the closure part 130 and the valve housing 140. In particular, FIG. 1 c shows an opening 134 of the closure part 130 and an outlet opening 12 of the valve housing 140 or a chamber 1 10. The breakthrough 134 can be achieved by a translatory movement 150 and the outlet opening 12 are positioned (ie aligned) in such a manner that an outlet channel is formed from the chamber 110 to the channel-shaped cavity 138 of the closure part 130. The closure member 130 may include one or more sealing members 160 disposed between the closure member 130 and the valve housing 140 to prevent leakage of the contents of a chamber 110 across a gap between the exterior of the closure member 130 and the interior of the valve housing 140. FIG. 1 d shows a plan view (from above) of a capsule 100. FIG. 1 d shows, in particular, the chambers 1 10, 120 for receiving (different) ingredients. In the example shown in FIG. 1 d, the first chamber 110 is formed as a (relatively large) main chamber and the second chamber 120 as a (relatively small) secondary chamber. From Fig. 1 d it can be seen that the valve housing 140 each form a wall of the one or more chambers 1 10, 120. The valve housing 140 encloses a (cylindrical) cavity 141, in which the closure member 130 can be placed and moved up and down in a translatory movement 150. Fig. 1 e shows an exemplary capsule 100 in a perspective view. As can be seen from FIG. 1 e, the capsule 100 preferably has a non-rotationally symmetrical shape. In particular, the capsule 100 may have a shape that interacts with a recess of a capsule-receiving unit of a beverage system such that the capsule 100 can only be placed in the capsule-receiving unit in a defined manner. Thus, the reliability in making a serving of a drink can be increased.

The capsule 100 described in this document can thus consist of at least three components, in particular a sealing film 102, a valve 130, 140 and a capsule body 101. Further, at the discharge end 132 of the valve 130, 140, a nozzle may be used to enhance the quality of a liquid jet from the capsule 100. In particular, a nozzle can be pressed in a lower region 132 of the valve 130, 140 in order to bring about an improvement in the outlet geometry.

Possibly. For example, at the lower portion 132 of the valve 130, 140, another sealing foil (not shown) sealing the lower portion 132 of the valve 130, 140 (i.e., the outlet of the capsule 100) may be used. This optional film can be removed by a user or cut by means of the valve 130, 140, in particular by means of the movable closure part 130 of the valve 130, 140.

As shown in the figures, the capsule 100 may comprise at least two separate chambers 1 10, 120, wherein a large part of the capsule volume are formed by a first chamber 1 10, which may be filled with a first ingredient (in particular with a first liquid). At least one second chamber 120 may be smaller than the first chamber (ie, the main chamber) 110 and may be filled with a second ingredient (especially a second liquid). The ingredients (especially the liquids) may include a fruit syrup, beverage concentrates, and / or other substances that may be used to prepare beverages, eg, alcoholic liquids containing up to 100% alcohol.

The capsule 100 may be sealed with a sealing film 102. For example, a PET film 102 may be applied by heat sealing or in an ultrasonic welding process. The capsule body 102 and / or the valve 130, 140 may be made of plastic. In this case, at least partially different materials can be used. Exemplary materials are PET, PE, PP or PBT. In particular, the closure part 130 and the valve housing 140 may comprise different materials. Thus, a bonding and / or welding of the closure part 130 and the valve housing 140 can be avoided in a reliable and efficient manner. In particular, such a stick-slip effect between different components of a capsule 100 can be avoided. The sealing of a capsule 100 can take place via one or more sealing lips or sealing elements 160 on the translation valve 130, 140. The sealing lips 160 that encircle the closure part 130 radially can subdivide the valve 130, 140 into several sections in the axial direction. The mutually separated portions can thereby the closed and open state of the openings or openings 1 1 1, 121, 1 12, 122 of the valve housing 140 and the chambers 1 10, 120 effect.

As already stated above, by depressing (in the direction 150) of the closure part 130 of the valve 130, 140, the openings 133, 135, 134, 136 of the closure part 130 can be made to communicate with the openings 11 1, 12, 121, 122 of the valve housing 140 and the chambers 1 10, 120 are aligned so that inlet and / or outlet channels arise. The capsule 100 is then in an open state. Due to the higher inlet openings 1 1 1, 1 12, a flushing medium (eg compressed air or gas) may optionally be passed from a gas cylinder into the chambers 1 10, 120 of the capsule. As a result, the ingredients contained therein (in particular liquids) expelled. Alternatively or additionally, a liquid can also be driven as flushing medium through the chambers 110, 120 in order to produce and rinse off an ingredient mixture with the ingredients of the chambers 110, 120.

The effluent through the outlet openings 1 12, 122 liquid may mix within a channel-shaped cavity 138 of the valve 130, 140 with an additional liquid flow. The liquid stream may be passed through a lance of a beverage system for opening the capsule 100 into the channel-shaped cavity 138 of the valve 130, 140.

The outlet openings 1 12, 122 of the different chambers 1 10, 120 may have a different height. In particular, the outlet opening 122 of the second chamber 120 can be higher than the outlet opening 1 12 of the first chamber 1 10 (as shown in Fig. 1 a). Thus, a reliable mixing of the ingredients within the channel-shaped cavity 138 can be effected.

2a shows a block diagram of an exemplary capsule system 200. The capsule system 200 includes a controller 201 configured to control the manufacturing process (portion) of a beverage. A user may hand over a capsule 100 to the system 200 (into a dedicated capsule-receiving unit of the system 200). The capsule can then optionally be transferred via optional conveying means (eg via a transport carriage) to a processing position 232 in the interior of a housing of the capsule system 200. The means of transport may be activated by the user (eg by pressing a button or directly by inserting the capsule 100). Upon arrival of the capsule 100 at the processing position 232, the manufacturing process can then be initiated. As part of the manufacturing process, the control unit 201 causes an opening means 220 to open the capsule 100 (eg a (hollow) needle or lance) to the capsule 100. For this purpose, an actuator 204 can be actuated, which brings the opening means 220 and the capsule 100 in order to open the capsule 100. Of Furthermore, a further actuator 203 can be actuated in order to press a flushing medium (for example from a container 202 of the system 200) into the capsule 100 in order to flush at least one chamber 1 10, 120 in the capsule 100. By opening the capsule 100 and possibly by flushing one or more chambers 110, 120 of the capsule 100, the contents of the one or more chambers 110, 120 can flow out of the capsule 100. Below a dispensing unit 206 of the system 200, a cup 210 may be positioned in which the beverage to be created is provided to the user. The system 200 may be configured such that an ingredient mixture 205 (including the ingredients and optionally a rinse medium) from the one or more chambers 110, 120 of the capsule 100 flows directly into the cup 210 through the dispensing unit 206.

The system 200 may also be configured to load more one or more supplemental liquids 215 (e.g., from a container 212) into the cup 210 for the beverage to be created. The supplemental liquid 215 may be e.g. Include alcohol. In this case, the additional liquid 215 can be transferred through the channel-shaped cavity 138 of the valve 130, 140 of a capsule 100 in the cup 210. Thus, a reliable mixing of a beverage can be effected.

By means of the capsule or beverage system 200 shown in FIG. 2 a, a mixed beverage can be produced in a reliable manner without polluting the capsule or beverage system 200.

2b shows details relating to an exemplary opening means 220 for opening a capsule 100. The opening means 220 comprises a rod 221, which may possibly be hollow. The rod 221 can be used to open a capsule 100 and in particular the valves 130, 140 of a capsule 100. The rod 221 can be moved down to open the capsule 100 by an actuator 204. In this case, the rod 221 at the lower end of the rod 221 may have a tip 222 in order to pierce the cover 102 of the capsule 100 in the region of the channel-shaped cavity 138 of the closure part 130 of the valve 130, 140 of the capsule 100. The rod 221 can thus be designed as a lance.

The closure part 130 may have an at least partially circumferential rib or an at least partially encircling rib on the inner wall facing the cavity 138 137 have. The rod 221 may have a diameter such that the rod 221 may be passed through the partially circumferential rib 137. However, the rod 221 may have an opening land or shoulder 227 in a certain area, which presses on the rib 137 of the closure member 130 when the rod 221 is driven down. Thus, the rod 221 can press the closure member 130 in the direction of movement 150 and thus convert the valve 130, 140 in the open state. In addition, the cavity 138 can be sealed by the rib 137 and by the shoulder 227, so that above the shoulder 227, a sealed cavity 253 between the rod 221 and the inner wall of the closure member 130 is formed.

The opening means 220 may comprise a housing 250 through which the rod 221 is guided. Furthermore, a seal 252 can be arranged on the housing 252, which seal the housing 252 and the cover 102 of the capsule 100. In particular, a flushing channel 251 can be formed by the seal 252 from the housing 252 to the capsule 100, in particular to the sealed cavity 253. The flushing medium 261 can then be passed through the flushing channel 251 in the sealed cavity 253 and from there through the inlet openings 1 1 1, 1 12 in the chambers 1 10, 120 of the capsule 100, in particular pressed. The rod 221 may be formed as a hollow rod or pipe. Thus, an additive liquid 215 for a beverage to be produced can be efficiently guided through the hollow rod via the channel-shaped cavity 138 of the closure part 130 of the capsule 100 into a cup 210. Fig. 2c shows a section through a (hollow) rod 221 and through the closure member 130. In particular, Fig. 2c shows how the rib 137 of the closure member 130 can serve as a support for the shoulder 227 of the rod 221 to the closure member 130 of the closed position to move to the open position. It may be advantageous to reseal the valve 130, 140 of a capsule 100 after preparation of a beverage. In particular, it is thus possible to prevent the contents that have remained in the one or more chambers 110, 120 of a capsule 100 from leaking, thereby contaminating the beverage system 200. The rod 221 may for this purpose have a closure web or wings 237 which can act from below on the rib 137 of the closure member 130 to pull the closure member 130 upwardly to the closed position. Such a closure web 237 is shown in Fig. 2c. The closing web 237 may be formed as a locally limited one or more wings on the rod 221, for example.

As shown in FIG. 2d, the rib 137 of the closure member 130 may include one or more breaks 257 formed such that the one or more wings 237 may pass the rib 137 when the rod 221 has a certain angle of rotation (eg, a first angle of rotation) Rotational position). On the other hand, rotation of the rod 221 (e.g., into a second rotational position) may cause the one or more vanes 237 to act on the rib 137 of the closure member 130 upon a raising of the rod 221.

FIG. 2e shows the rib 137 of a closure part 130 with the breaks 257 in a top view (from above). FIG. 2e shows the rod 221 and the wings of the occlusion ridge 237 in a plan view (from above) when the rod 221 is moved down to open the valve 130, 140 of a capsule 200. On the other hand, Fig. 2g shows the rod

221 and the wings of the closing ridge 237 in a plan view (from below), when the rod 221 is moved up to close the valve 130, 140 of a capsule 200. The rod 221 has been rotated by 90 ° in the illustrated example, so that the closing web 237 can act on the rib 137 of the closure part 130 when driving upwards to close the valve 130, 140.

FIGS. 3a and 3b show exemplary outlet openings 12, 121 for a main chamber 110 and for an auxiliary chamber 120. An outlet opening 12 may be wider at a lower edge than at an upper edge (see FIG. 3a), in order to ensure that the contents of a chamber 1 10 as completely as possible from the chamber 1 10 can be performed. Furthermore, the ratios of the outlet velocities of the ingredients can be flexibly changed by different geometries of the outlet openings 1 12, 122.

The beverage system 200 may thus be a needle at a lower end of the rod 221

222 to puncture the sealing film 102 of a capsule 100. The Drinking system 200 may open valve 130, 140 by urging closure member 130 of valve 130, 140 downwardly through rod 221, particularly through a liquid lance. In this case, a shoulder 227 of the rod 221 presses on an inwardly projecting rib 137 on the inside of the closure part 130 of the valve 130, 140. Furthermore, the rod 221 can have one or more closing elements 237. A closing element 237 serves to pull the closure part 130 of the valve 130, 140 back upwards after the beverage dispensing in order to close the capsule 100. The one or more closure members 237 may be formed as wings on the rod 221. After the one or more closing elements 237 have passed the rib 137 in the closure part 130 of the valve, the rod 221 can be moved by means of a

Sliding (not shown) are rotated (see Fig. 2g compared to Fig. 2f). When the rod 221 is moved upwards, the one or more closing elements 237 then take along the closure part 130 of the valve 130, 140, in particular until the rod 221 is again rotated back through the link.

The capsule 100 may include an inner and / or an outer collar and one or more partitions. The collars and / or partitions can serve as sealing surfaces for the cover 102, in particular the cover film. The setting of the discharge speed of the contents of the one or more chambers 1 10, 120 can be done via the insertion depth of the closure part 130 of the valve 130, 140. As shown in Figures 3a and 3b, the outlet openings 1 12, 122 of the one or more chambers 1 10, 120 can be opened by the position of the closure member 130 more or less wide. Thus, the volume flow of leaking ingredients can be changed.

Alternatively or additionally, the volume flow of the exiting ingredients via the pressure of the flushing medium 261 at the inlet openings 1 1 1, 121 are controlled. By way of a corresponding geometry of the apertures or openings (in particular of the outlet openings) 12, 122 of a capsule 100, the ratio between the outlet velocity of the different chambers 110, 120 can be influenced. In addition, the different outlet openings 1 12, 122 of the different chambers 1 10, 120 have different shapes (as shown for example in Figures 3a and 3b), so that the ratio of the volume flows of the ingredients from the different chambers 1 10, 120 are changed by the insertion depth of the closure part 130 of the valve 130, 140 can. For example, in the example illustrated in FIG. 3 b, the outlet opening 122 of the second (small) chamber 120 is restricted by the size of the aperture in the closure part 130 of the valve 130, 140 and constant regardless of the degree of opening of the valve 130, 140.

By using a multi-chamber capsule 100 different substances or ingredients in different chambers 1 10, 120 of the capsule 100 can be stored separately, whereby the shelf life of the ingredients of a capsule 100 can be extended.

Through the construction of a capsule 100 described in this document, ingredients can be efficiently removed from a capsule 100 to make a beverage.

Furthermore, contamination of a beverage system 200 by the contents of a capsule 100 can be reliably prevented by the measures described in this document. This can be achieved in particular in that the capsule 100 can be closed again after production of a beverage. Furthermore, by the described construction of a capsule 100, a contact between the rod 221 (in particular the lance) and the contents of the capsule 100 can be avoided. By centrally supplying a liquid 215 from a beverage system 200, a liquid jet having a high uniformity can be provided, allowing for reliable mixing of the contents of a capsule 100 with externally supplied liquids 215. The described beverage system 200 uses a small number of needles 222. In the example shown in FIG. 2b, the beverage system 200 has only a single needle 222. In addition, if necessary, the use of a needle 222 may be completely dispensed with, for example if the cavity 138 of the closure part 130 is not separated from the one Cover 102 of the capsule 100 is covered. Thus, the cost of a beverage system 200 can be reduced and security for a user can be increased.

By using a molded second chamber 120 (see, e.g., Fig. 1e), a unique insertion position of the capsule 100 in a capsule receiving unit of a beverage system 200 can be defined. Thus, operating errors of the beverage system 200 when inserting a capsule 100 can be avoided.

The identification of a capsule 100 can take place via an optical feature and / or via NFC (Near Field Communication) and / or via RFID (Radio Frequency ID). Thus, multiple capsules 100 of different capsule type with different ingredients can be provided for the production of different types of drinks. The capsules 100 may have an identifier indicating the type of capsule and thus the beverage to be produced. The beverage system 200, in particular the control unit 201, can be set up to determine the type of capsule on the basis of the identifier. Further, the control unit 201 may control the manufacturing process of a beverage depending on the detected capsule type. Thus, in a beverage system 200, beverages of different beverage types can be produced in a comfortable manner. The capsule 100 may include (e.g., mechanical) means for preventing reuse of a capsule 100 already in use. In particular, for this purpose, the shape of a capsule 100 in the manufacture of a beverage or in the use of a capsule 100 can be changed, so that a reuse is prevented. For example, a locking lug and / or a predetermined breaking point can be defined, which prevent a complete pushing back of the closure part 130 of the valve 130, 140 into the original dispensing position.

Alternatively or in addition to the use of a translation valve 130, 140, a rotary valve may be used. Here, the closure part 130 of the valve is formed such that the corresponding openings 1 1 1, 121, 1 12, 122 to the chambers 1 10, 120 of the capsule 100 can be opened and closed by rotation of the closure member 130. The rod 221 can by rotation of the closure part 130 open or close the capsule 100 and may possibly change the outlet speed by changing the opening angle.

The internal valve 130, 104 may be replaced, as shown in FIG. 4a, by a chamber wall 440 which is solid and provided with suitable flaps 412, 422 at the outlet. The flaps 412, 422 open and close the respective chambers 1 10, 120 of the capsule 100 and can be opened by means of the rod 221 via predetermined breaking points 41 1, 412. After a beverage has been dispensed, the stick 221 retreats from the capsule 100. The resealing of the outlet openings 1 12, 122 can be effected automatically due to the elasticity of the material of the chamber wall 440 and the predetermined breaking points 41 1, 412.

The introduction of a flushing medium 261 in the one or more chambers 1 10, 120 of the capsule 100 for faster emptying can also be provided in this case. For example, as shown in FIG. 4a, the lid 102 of the capsule 100 may be pierced to create openings in the one or more chambers 110, 120. Alternatively or additionally, predetermined breaking points can be provided in the wall 400 in the upper region of the capsule 100, which can be broken by the rod 221 in order to produce inlet openings 11 1, 121 into the chambers 110, 120. The setting of the discharge speed can be done by opening a certain number of predetermined breaking points 41 1 or flaps 412 in a chamber 1 10. The individual predetermined breaking points 41 1 or flaps 412 may be e.g. be opened or closed again by a rotation of the rod 221. For focusing the jet at the lower outlet of a capsule 100, a nozzle 450 can be used as an additional capsule component (see FIG. 4b).

The present invention is not limited to the embodiments shown. In particular, it should be noted that the description and figures are only intended to illustrate the principle of the proposed system and / or the proposed capsule.
