Description

[0001] Capsule or capsule construction, preparation device for preparing a coffee beverage or tea beverage using a capsule or capsule construction and method for preparing a coffee beverage or tea beverage

[0002] The invention relates to a capsule or capsule construction, a preparation device for preparing a coffee beverage or tea beverage using a capsule or capsule construction and a method for preparing a coffee beverage or tea beverage.

[0003] A coffee beverage is made from two ingredients: coffee beans, which are roasted and ground to varying degrees, and water. Tea beverages are usually made from dried or fresh tea leaves, fruits and / or herbs, and water. Hot water is poured over the tea leaves, fruits and / or herbs and left to steep for a certain amount of time before the tea leaves, fruits and / or herbs are removed from the infusion, i.e. the resulting tea beverage. Depending on the type of tea, such as green tea or black tea, herbal tea or fruit tea, different water temperatures and / or brewing times are used. The tea leaves, fruits and / or herbs can be used in varying amounts as plant parts, for example as leaves, and / or finely, for example crushed, or as powder.

[0004] While there is a real science to the different types of coffee, the fineness of the grind, the brewing temperature and the pressure within a coffee machine, and when preparing tea, especially green tea or black tea, great attention is paid to water temperature, brewing time and, especially in the case of green tea, the number of infusions, no special attention has been paid to the quality of the water to date.

[0005] The quality of the finished coffee or tea can vary greatly depending on the water quality. Typically, existing tap water is used to fill a water tank inside the machine, or the machine is connected directly to the mains. The goal is to design a capsule or capsule construction specifically for water that contains water of a suitable or desired quality. This ensures that, regardless of the location in the world, regardless of latitude, a consistently high quality of coffee or tea with a consistent aroma is achieved.

[0006] In addition, you do not need a water connection in the vicinity of the machine.

[0007] At the same time, choosing the right water quality, packaged in a capsule, can also prevent the machine from becoming calcified.

[0008] Coffee machines are often found in offices, meeting rooms, and hotel rooms. The water tank is either empty or used up. If suitable water isn't available, the solution is to fill the water tank with still water from any nearby mineral water bottle.

[0009] In terms of both quantity and total, water consumption can be reduced because “standing” water in the tank is often emptied and replaced with new, fresh water before coffee preparation.

[0010] Conventional coffee machines typically use a water tank to provide the water for brewing coffee. Standardized or separate coffee capsules are often used.

[0011] For machines for preparing tea, it is intended that the herb of tea plants, the fruits and / or herbs as well as the water for preparation are kept individually stored, each added individually or are present together but separately in a capsule or in a corresponding container and the capsule or container is fed to the machine as required.

[0012] The present invention solves these water quality problems with various design solutions.

[0013] It is therefore the object of the invention to provide a capsule or capsule construction, a preparation device for preparing a coffee beverage or tea beverage using a capsule or capsule construction and a method for preparing a coffee beverage or tea beverage.In a first aspect, the invention achieves in the specified application that a capsule construction is created for holding water and / or coffee or tea, wherein the capsule or capsule construction comprises at least one chamber or container, wherein the at least one chamber or the at least one container contains the water or a coffee-water mixture or a tea-water mixture, or that in the case of two chambers or two containers, a first of the two chambers or a first of the two containers contains the water and a second of the two chambers or a second of the two containers contains the coffee or tea, so that on the one hand the suitable or desired water is kept separate from a coffee or tea or on the other hand the suitable or desired water is already kept as a coffee-water mixture or a tea-water mixture.It is advantageous to use only the ingredients or components required for the individual preparation of a coffee or tea beverage, in a needs-based and portioned manner.

[0014] A second aspect of the invention relates to a preparation device for preparing a coffee beverage or tea beverage using the capsule or the capsule construction, wherein a heating device and a conveying device for water and / or for coffee or tea or for a coffee-water mixture or a tea-water mixture are provided, wherein a heating rod or heating tube is provided as the heating device, wherein the heating rod or the heating tube can be pierced or inserted into the capsule or capsule construction or that the water and / or the coffee or tea or the coffee-water mixture or a tea-water mixture can be passed through the heating device and that the conveying device is a piston driven by means of a translation drive or a pump.This advantageously allows the water or coffee, for example as a fluid concentrate or tea, for example as a fluid concentrate or a coffee-water mixture or a tea-water mixture, to be individually heated in preparation and conveyed directly into a drinking vessel for preparation or to be mixed for preparation, allowed to steep if necessary and conveyed into a drinking vessel or to be conveyed through coffee or tea and conveyed into a drinking vessel.

[0015] A third aspect of the invention relates to a method for preparing a coffee beverage or tea beverage with the preparation device and using the capsule or capsule construction, wherein a capsule or a capsule construction containing water or coffee or tea or a coffee-water mixture or tea-water mixture is arranged in or on the preparation device, that the water or the coffee-water mixture or the tea-water mixture is then heated to a target temperature by means of a heating device and after the target temperature has been reached, at least the heated water or the coffee-water mixture or the tea-water mixture is pressed out of the capsule or a capsule construction by means of a conveying device and the prepared coffee or tea is discharged.Advantageously, individual or desired coffee drinks or tea drinks can be prepared using the appropriate or desired water or a coffee-water mixture or the tea-water mixture with the appropriate or desired water.

[0016] However, the water can also be heated when the water or the coffee-water mixture or the tea-water mixture is conveyed by means of the conveying device, by passing the water or the coffee-water mixture or the tea-water mixture through the heating device.

[0017] The water or the coffee-water mixture or the tea-water mixture can also be pumped through the heating device.

[0018] By filling the capsule or capsule construction specifically for water with decalcified, selected, and germ-free water, consistent coffee or tea quality can be ensured. This is important to preserve the taste and aroma of the coffee or tea. This water is drawn from a selected Alpine spring, for example, fresh Alpine water.

[0019] The option of offering pre-made coffee or tea in special capsules or containers is also practical. This allows for different coffee or tea varieties or blends to be made available with high quality to meet the individual preferences of coffee or tea drinkers.

[0020] By using selected, tested Alpine water and pre-portioned capsules or capsule construction, especially for water as well as with ready-made coffee or tea, users can enjoy consistently high quality coffee or tea.

[0021] The use of portioned capsules or capsule constructions for water and / or coffee, as well as coffee-water mixtures with ready-made coffee for water and / or tea, and tea-water mixtures with ready-made tea, enable simple and quick preparation. The use of compostable capsules or containers is an environmentally friendly solution. The use of softened water also helps extend the lifespan of the coffee machine or tea maker by reducing limescale deposits.

[0022] The capsule or capsule construction, for example, comprises a paper material or paper composite material as a combination of different materials. The components of the paper material come from renewable raw materials.

[0023] In addition to a paper material or paper composite material as a combination of different materials, other environmentally friendly materials or material combinations that are compostable and / or recyclable are also considered. Composite materials or combinations of different materials are also possible. For example, recycled plastics or recyclable plastics as well as compostable plastics are also possible. Combined paper-plastic combinations are also possible. Other materials or material combinations not mentioned here that are environmentally friendly, compostable and / or recyclable are also possible for the capsule or container.

[0024] A composite or material combination which includes a metal layer or metal coating in addition to other materials can also be used.

[0025] Advantageous embodiments of the invention are presented in the subclaims.

[0026] Advantageously, the capsule or capsule construction has a capsule base with an internal, sealed, movable chamber base or container base and / or a capsule head with an internal, sealed, movable or pivotable or tiltable chamber lid or container lid, or the chamber or container has a movable or pivotable or tiltable or bellows-shaped chamber wall or container wall, so that the contents of the respective capsule or capsule construction can be reliably and unchanged stored in the capsule and the capsule can be reliably emptied.

[0027] By providing the chamber lid or container lid, the chamber floor or container floor, or the chamber wall or container wall with at least one membrane or predetermined breaking point or predetermined tear point, emptying is facilitated. Access to a heating device is also facilitated.

[0028] By the capsule or capsule construction having a capsule head and / or a capsule base, wherein the capsule head or the capsule base has at least one membrane or a wall with at least one predetermined breaking point or at least one predetermined tear point, access to the capsule or capsule construction and / or emptying of the capsule or capsule construction is facilitated.

[0029] By having the at least one chamber or the at least one container with an outlet side, an outlet wall or an outlet opening, emptying is facilitated.

[0030] By the membrane comprising a filter or by at least one filter being provided in the region of the at least one predetermined breaking point or the at least one predetermined tear point or in the region of the outlet side, the outlet wall or the outlet opening, any impurities as well as coffee powder or tea constituents or other residues or suspended particles can be retained.

[0031] By having at least one membrane or at least one partition or at least one chamber wall between two chambers or containers, unwanted mixing or contamination by coffee powder or tea ingredients or other residues or suspended particles in the unused chambers or containers as well as during preparation is prevented.

[0032] By having at least one membrane or at least one partition or at least one chamber wall between two chambers or containers at least one predetermined breaking point or at least one predetermined tear point, opening of the membrane or partition or chamber wall and mixing of the chamber contents or container contents during the preparation of the respective beverage is promoted.

[0033] By making the capsule or capsule construction from a paper material or a paper-containing composite material, or from a paper-containing composite material, or from other environmentally friendly materials or material combinations, or from a compostable and / or recyclable material or material composite, handling during use and disposal after use are facilitated. Sustainability is also promoted. Compostable capsules or capsule constructions are therefore possible for water and / or coffee, a coffee-water mixture, and for water and / or tea, and a tea-water mixture.

[0034] By including liquid or powdered concentrate or instant coffee or instant tea in the coffee-water mixture or tea-water mixture, the preparation of the respective beverage is simplified or facilitated.

[0035] By containing the coffee as powder or as liquid or powder concentrate or as instant coffee or by containing the tea as herb from tea plants, as fruits and / or as herbs and / or parts thereof or as mixtures thereof, the preparation of the respective beverage can already be started or triggered or prepared in the capsule or capsule construction and then the finished beverage can be dispensed by emptying the capsule or capsule construction.

[0036] By providing a connection adapter or a mechanical interface to a preparation device and / or by the capsule or capsule structure and / or the at least one chamber or the at least one container or two chambers or two containers together or in combination having a cylindrical shape or any other desired shape as a container, the capsule or capsule structure can be constructed and used universally. Furthermore, the construction of the capsule or capsule structure and the preparation device can be simplified.

[0037] By using a toggle lever with an eccentric drive, a toggle lever drive, a rack and pinion drive, a spindle drive, or a linear drive, the translational drive of the brewing device promotes reliable emptying of the respective chamber or container of the capsule or capsule construction. Depending on the beverage and taste, different water pressures are required, with which it is forced or directed through coffee powder or tea, for example.

[0038] By providing a connection adapter, a mechanical interface, or a receptacle for the capsule or capsule construction in the preparation device, different shapes and models of the capsule or capsule construction can be used. By allowing a separate coffee capsule or tea capsule to be inserted into the preparation device and heated water to be supplied to the separate coffee capsule or tea capsule, any other coffee capsule or tea capsule can be used, and corresponding beverages can be prepared with these coffee capsules or tea capsules and water of the suitable or desired water quality in the capsules or capsule constructions according to the invention. A high degree of flexibility in use is achieved.

[0039] A simple yet reliable construction is achieved by the conveying device in the method and / or in the preparation device compressing the capsule or capsule structure, or a part of the capsule or capsule structure, by means of a piston or pressing it into the capsule or capsule structure. Advantageously, the piston can compress the capsule or capsule structure itself or displace the chamber base or container base, or the chamber lid or container lid within the chamber or container.

[0040] In the method, the capsule or capsule construction containing separately contained water and coffee or water and tea is first compressed by means of the piston of the conveying device and the water is mixed with the coffee or the water with the tea and then the capsule or capsule construction is compressed by means of the piston of the conveying device and the prepared coffee or tea is discharged.

[0041] By feeding the water from the capsule or capsule assembly to a separate coffee or tea capsule via the conveyor system, and discharging the prepared coffee or tea, the process allows for individual coffee or tea to be prepared using the appropriate or desired water quality. Furthermore, the brewing time for the coffee or tea can be influenced and adjusted.

[0042] By inserting or piercing a heating element into the capsule or capsule structure, the heating occurs directly within the capsule or capsule structure, without first conveying the water to an additional or separate boiler or brewing chamber. Alternatively, the heating of the water, coffee-water mixture, or tea-water mixture involves passing the water, coffee-water mixture, or tea-water mixture through the heating device and thus heating it immediately upon conveyance.

[0043] Several embodiments of the invention are illustrated in the drawings and described in more detail below. They show:

[0044] Fig. 1a to 1d show a basic design of a coffee machine or tea machine or tea vending machine as a preparation device with two separate insertion points, wherein a first of the two insertion points is provided for a standard or separate coffee capsule or tea capsule and a second of the two insertion points is provided for a capsule with water, Fig. 2a to 2d show a basic design of a coffee machine or tea machine or tea vending machine as a preparation device with one insertion point for a combined capsule for water and for coffee or tea, wherein the water and the coffee or tea are mechanically and thus spatially separated from one another in the capsule or capsule construction, Fig.3a and 3b a basic design of a coffee machine or tea machine or tea vending machine as a preparation device with an insertion point for a capsule with ready-made coffee or a suitable tea, for example an instant tea, wherein water and coffee or water and tea are already present and mixed together in the capsule or capsule construction, Fig. 4 a capsule or capsule construction with a bellows-shaped chamber wall or container wall,.

[0045] Fig. 5 is a schematic diagram of a preparation device with two separate insertion points, wherein a first of the two insertion points is provided for a standard or separate coffee capsule or tea capsule and a second of the two insertion points is provided for a capsule with water and

[0046] Fig. 6 shows the principle diagram of a piston driven by a toggle lever with eccentric drive as a translation drive.

[0047] Figures 1a to 1d show, in various views and detailed representations, a basic embodiment of a coffee machine or tea machine or tea vending machine as a preparation device 7 according to the invention with two separate insertion points 9, wherein a first of the two insertion points 9 is provided for a standard or separate coffee capsule 8 or tea capsule 8 and a second of the two insertion points 9 is provided for a capsule 1 according to the invention containing water. The capsule construction 1 can be made from a paper material or paper composite material as a combination of different materials or from other environmentally friendly materials or material combinations. The capsule construction 1 can be cylindrical and comprise a cylindrical container 2. Likewise, the capsule construction 1 or the container 2 for the water and / or a portioned brewing agent can also have any other desired shape.

[0048] The capsule 1 or capsule construction 1 as well as the standard or separate coffee capsule 8 or tea capsule 8 can be inserted into the preparation device 7 from above, for example.

[0049] One aspect of the invention relates to a capsule 1 or capsule construction 1 which comprises, for example, a paper material or a paper-containing composite material or is produced from a paper-containing composite material or from other environmentally friendly materials or material combinations and is designed as a container 2 or chamber 2 for a portioned brewing substance, in particular decalcified water, which can be heated or is heated for the preparation of a brewed beverage with the aid of a heating rod 5 of a heating device 5 which can be pierced, inserted or pierced into the capsule 1, so that cold water is heated, wherein the capsule 1 has a receiving part for a conveying device 4 in the preparation device 7 according to the invention.For example, the capsule has a capsule head 10 with an internal, sealed, movable container base 19, on which a piston 6 driven by a translation drive, for example by a linear drive, acts.

[0050] The invention of the preparation device 7 according to the invention alternatively comprises, for example, a press-ram stroke based on the toggle lever principle. The press-ram stroke or the driven piston 6 generates an extrusion stroke for the water from the capsule or capsule construction 1 for water, which is connected or combined with a separate coffee capsule 8 or tea capsule 8.

[0051] The coffee capsule 8 or tea capsule 8 can be arranged in a capsule cage 13 known per se and at least partially enclosed by it. The capsule cage 13 with the separate coffee capsule 8 or tea capsule 8 is pressed against a pyramid plate 14 and together form a pressure-tight brewing chamber 15. Domes in the end of the capsule cage 13 opposite the pyramid plate 14 pierce the housing, for example made of aluminum or plastic, of the separate coffee capsule 8 or tea capsule 8. According to the invention, hot water from the capsule 1 or capsule construction 1 for the water is pressed under pressure into the brewing chamber 15 by the piston 6 via the toggle lever principle. The pressure inside the separate coffee capsule 8 or tea capsule 8 increases and causes the membrane 16 on the side facing the pyramid plate 14 to burst or open by means of cutting devices, spikes, or predetermined breaking points.The coffee or tea is brewed in the separate coffee capsule 8 or poured into the tea capsule 8 and passed via the pyramid plate 14 to the coffee outlet 17 or tea outlet 17.

[0052] Figures 2a to 2d show, in various views and detailed representations, a basic design of a coffee machine or tea machine or tea vending machine as a preparation device 7 with an insertion point 9 for a combined capsule 1 for water and for coffee or tea, wherein the water and the coffee or tea are mechanically and thus spatially separated from one another in the sleeve. Capsule constructions 1 made of paper material or paper composite material, as a combination of different materials or of other environmentally friendly materials or material combinations, are considered here. These capsule constructions are designed as a cylindrical container or as any other desired container shape and contain a portioned brewing agent in the form of water and portioned coffee or tea separately from one another.

[0053] The capsule 1 or capsule construction 1 can be inserted into the preparation device 7, for example, from above.

[0054] One aspect of the invention further relates to a structure of a capsule 1 or capsule construction 1, which, for example, comprises a paper material or a paper-containing composite material or is made from a paper-containing composite material or from other environmentally friendly materials or material combinations. The capsule 1 or capsule construction 1 comprises two containers 2 or chambers 2, which are separated by at least one membrane 16 or at least one partition 12 or by at least one chamber wall 3 or container wall 3. The chambers 2 or containers 2 contain the brewing ingredients necessary for preparing a portioned beverage in the form of water and portioned coffee or tea, wherein a first of the chambers 2 contains water, for example decalcified water, and a second of the chambers 2 contains coffee or tea in the form of powder or as a liquid or powdered concentrate or as instant coffee or tea.To prepare a brewed beverage, a heating rod 5 can be or is inserted into the capsule 1 and the container 2 with the water. The cold water can be or is heated. According to the invention, after the water has been heated by means of the heating rod 5, the capsule 1 or capsule construction 1 is compressed under pressure by the piston 6 as a conveying device 4 via the toggle lever principle or by means of another translational drive, and the at least one membrane 16 or the at least one partition wall 12 or the at least one chamber wall 3 or container wall 3 are destroyed at predetermined breaking points or predetermined tear points or break or tear in a controlled manner and the heated water and the coffee as powder, for example ground beans, or as liquid or powder concentrate or as instant coffee or tea, for example as herb or powder, mix.By means of the piston 6 and / or the heated water, the pressure inside the capsule 1 or the capsule structure 1 or the chamber 2 or the container 2 continues to rise, causing an outlet wall, outlet opening, or a membrane 16 on the underside or outlet side to burst or open by means of cutting devices, spikes, or predetermined breaking points. The coffee or tea is then directed to the coffee outlet 17 or tea outlet 17 and into the cup or the like, or directly into the cup or the like.

[0055] The capsule 1 comprises a receiving part for a conveying device 4 in the machine as a preparation device 7. The capsule 1 or capsule structure 1 has a capsule base 11 or a capsule head 10 with an internal, sealed, movable container base 19 or container lid 18 or container wall 3. Likewise, the capsule head 10 or capsule base 11 can have a membrane 16 or a wall with predetermined breaking points or predetermined tear points. The machine remains very clean because the brewing process takes place within the capsule 1.

[0056] Figures 3a and 3b show, in various views and detailed representations, a basic design of a coffee machine or tea machine or tea vending machine as a preparation device 7 with an insertion point 9 for a capsule 1 or capsule construction 1 with a coffee-water mixture, for example as ready-made coffee or a tea-water mixture with a suitable tea, for example an instant tea, wherein water and coffee or water and tea are already present and mixed together in the capsule 1 or capsule construction 1. Reference is also made to Figures 2a and 2b, since these views and detailed representations also illustrate this exemplary embodiment. The capsule 1 or capsule construction 1 comprises a paper material or paper composite material as a combination of different materials or other environmentally friendly materials or material combinations.The capsule 1 or capsule construction 1 has a cylindrical shape and comprises a container 2. The capsule 1 or capsule construction 1 can also have any other shape. The container 2 in the capsule 1 or capsule construction 1 is designed for a portioned ready-to-use coffee or tea.

[0057] This aspect of the invention relates to a capsule 1 or capsule construction 1, which, for example, comprises a paper material or a paper-containing composite material or is made from a paper-containing composite material or from other environmentally friendly materials or material combinations. The capsule 1 or capsule construction 1 comprises a container 2 or a chamber 2. It is provided that a portioned coffee-water mixture can be produced as ready-made coffee or a tea-water mixture as ready-made tea using the capsule 1 or capsule construction 1. To prepare the preparation of a hot beverage, a heating rod 5 of a heating device 5 is inserted into the chamber 2 or the container 2 of the capsule 1 or capsule construction 1.By means of the heating rod 5, which can be pierced or inserted into the capsule and into the chamber 2 or the container 2, the portioned coffee-water mixture is heated as cold ready-made coffee or the tea-water mixture as cold ready-made tea, for example a mixture of coffee or tea and water, or a water-diluted coffee concentrate or tea concentrate, or a pre-dissolved instant coffee or instant tea. The capsule 1 or capsule construction 1 comprises a receiving part for a conveying device 4 in the respective preparation machine or preparation device 7, wherein the capsule 1 has a capsule head 10 with an internal, sealed, movable container wall 3 or container lid 18 or a capsule base 11 with an internal, sealed, movable container base 19. The capsule head 10 or capsule base 11 can also have a membrane 16 or wall with predetermined breaking points or predetermined tear points.The machine remains very clean because the entire process takes place within capsule 1 or capsule construction 1.

[0058] According to the invention, after heating the coffee-water mixture or the tea-water mixture, the capsule 1 or capsule structure 1 is compressed under pressure as ready-to-brew coffee or ready-to-brew tea by means of the heating element 5 via the toggle lever principle by the piston 6 as a conveying device 4, and the capsule head 10 with an internal, sealed, movable container lid 18 or a container wall 3 or a capsule base 11 with an internal, sealed, movable container base 19 is destroyed or breaks or tears at predetermined breaking points or is displaced, pivoted, or twisted for opening. An outlet side, an outlet wall is defined, or an outlet opening is formed. The heated ready-to-brew coffee or ready-to-brew tea is pressed out of the capsule 1 or capsule structure 1 by means of the piston 6 and is directed further to the coffee outlet 17 or tea outlet 17 and into the cup or the like, or directly into the cup or the like.

[0059] Fig. 4 shows various views and detailed representations of a capsule 1 or capsule structure 1 with a bellows-shaped chamber wall 3 or container wall 3 in an expanded or filled state at the top and in an emptied or compressed state at the bottom. This advantageously provides a reusable capsule 1 or capsule structure 1 that is also easy to operate or handle in the preparation device 7.

[0060] Figure 5 shows a schematic diagram of a preparation device with two separate insertion points 9, wherein a first of the two insertion points 9 is provided for a capsule 1 or capsule construction 1 according to the invention with a container 2 for water and a second of the two insertion points is provided for a standard or separate coffee capsule 8 or tea capsule 8. Between the first of the two insertion points 9 for the capsule 1 or capsule construction 1 according to the invention with water and the second of the two insertion points for the standard or separate coffee capsule 8 or tea capsule 8, a heating device 5 with a heating tube 5 is provided. The heating tube 5 is designed such that it can be inserted or pierced with one of its axial ends into the capsule 1 or capsule construction 1 according to the invention, on the one hand, and into the standard or separate coffee capsule 8 or tea capsule 8, on the other.For this purpose, at least the capsule 1 or capsule construction 1 moves towards and onto the heating tube 5. Likewise, the standard or separate coffee capsule 8 or tea capsule 8 can move towards the heating tube 5, or the heating tube 5 can move through or with the capsule 1 or capsule construction 1 towards the standard or separate coffee capsule 8 or tea capsule 8. The heating tube 5 has a heating coil and thus forms a type of continuous-flow heater. The container 2 of the capsule 1 or capsule construction 1 has a membrane 16 at the end facing the heating tube 5, which membrane can be pierced by the heating tube 5. Furthermore, a piston 6 driven by a translational drive is provided, which acts on a displaceable container base 19 and pushes this into the container 2 or into the capsule 1 or capsule construction 1 in the direction of the heating tube 5 and towards the standard or separate coffee capsule 8 or tea capsule 8.The translational drive for the piston 6 can be a toggle lever with eccentric drive, a drive using the toggle lever principle, a rack and pinion drive or a spindle drive or a linear drive.

[0061] Figure 6 shows the schematic diagram of a piston 6 of a conveying device 4 driven by a toggle lever with eccentric drive as a translational drive. An eccentrically mounted connecting rod 20 is connected to a toggle lever 21, which is connected on the one hand to a fixed bearing 22 and on the other hand to the piston 6, so that a movement of the connecting rod caused by the eccentric drive causes a movement of the toggle lever towards the piston 6 and thus the piston 6. The connecting rod is deflected by the toggle lever towards the piston. The piston 6 performs a linear movement. The movement of the piston

[0062] 6 is an oscillating movement.

[0063] To increase compatibility, a connection adapter or a mechanical interface to the preparation device is available.

[0064] The inventive method for preparing a coffee beverage or tea beverage with a preparation device 7 and using a capsule 1 or capsule construction 1 provides that a capsule 1 or a capsule construction 1 containing water and a separate standard or separate coffee capsule 8 containing coffee or a tea capsule 8 containing tea, or that a capsule 1 or a capsule construction 1 containing water and, separately therefrom in the same capsule 1, a capsule construction 1 containing coffee or tea, or that a capsule 1 or a capsule construction 1 containing a coffee-water mixture or a tea-water mixture is arranged in or on the preparation device. The water or the coffee-water mixture or the tea-water mixture is then heated to a target temperature by means of a heating device 5.After the target temperature has been reached, the heated water or the heated coffee-water mixture or the heated tea-water mixture is pressed out of the capsule 1 or a capsule construction 1 by means of a conveying device 4 and the prepared coffee or tea is discharged.

[0065] The conveying device 4 compresses the capsule 1 or the capsule construction 1 or a part of the capsule 1 or the capsule construction 1 using a piston 6. To prepare a coffee beverage or tea beverage with water and coffee or water and tea contained separately in the capsule 1 or the capsule construction 1, the capsule 1 or the capsule construction 1 is first compressed using the piston 6 of the conveying device 4. The water is mixed with the coffee or the water with the tea. The capsule 1 or the capsule construction 1 is then compressed using the piston 6 of the conveying device 4, and the prepared coffee or tea is discharged.

[0066] For the preparation of a coffee beverage or tea beverage separately with water contained in a capsule 1 or capsule construction 1 and a separate standard or separate coffee capsule 8 with coffee or tea capsule 8 with tea, the water from the capsule 1 or the capsule construction 1 is fed to the separate coffee capsule 8 or tea capsule 8 by means of the conveyor device 4 and the prepared coffee or tea is discharged.

[0067] To heat the water or the coffee-water mixture or the tea-water mixture, a heating rod 5 or a heating tube 5 is pierced or inserted into the capsule 1 or a capsule structure 1. Alternatively, to heat the water or the coffee-water mixture or the tea-water mixture, the water or the coffee-water mixture or the tea-water mixture is passed through the heating device 5.
