The invention relates to a system for making a given amount of beverage suitable for consumption using the extracted product containing exchangeable capsule, and a device containing a socket for holding the exchangeable capsule, and a device for issuing a fluid medium that is designed to supply a quantity of fluid, such as water, under pressure to the exchangeable capsule, with interchangeable capsule contains peripheral wall, a bottom closing the peripheral wall from the first end, and a closing element, the closing of the peripheral wall from the second end opposite the bottom, and the wall, the bottom and the closing element limiting the internal space containing extractable product, while the bottom contains the entrance area for supplying a quantity of fluid a device for issuing a fluid medium through the inlet zone into the capsule, with the closing element contains the output area for filing drink through the exit area of the capsule into the container.

Such systems are in themselves known. In this system, this capsule you can use with the input zone, through which fluid is fed into the capsule, and an output area, through which the prepared drink metered is supplied from the capsule. For holding the extracted product to open the Oh capsule at least the output area often supply the output layer. Also the output area can be provided to the input layer.

The disadvantage of this capsule is that with a limited dose of the extracted product in the capsule and a high pressure fluid as the drink may become lower than necessary.

The objective of the invention is to improve the above mentioned systems and, more specifically, improving the quality of the prepared drink.

For this purpose according to the invention has created a system for making a given amount of beverage suitable for consumption using the extracted product containing a replaceable capsule and the device containing the socket for holding the exchangeable capsule, and a device for issuing a fluid medium that is designed to supply a quantity of fluid, such as water, under pressure to the exchangeable capsule, with interchangeable capsule contains peripheral wall, a bottom closing the peripheral wall from the first end, and a closing element, the closing of the peripheral wall from the second end opposite the bottom, and a wall, a bottom closing element limit the inner space containing the extractable product, while the bottom contains the entry zone to supply the dose of the fluid device for issuing a fluid medium through the inlet zone into the capsule, thus closing e is ement contains the output area for filing drink through the exit area of the capsule into the container, thus the flow resistance of the entrance area of the capsule is less than the flow resistance of the output area when the capsule contains extractable product.

With the creation of the output zones with flow resistance, greater resistance to the flow of the input area when the capsule contains extractable product, you can get a buildup of pressure on the extractable product in the capsule, thus contributing to the improvement of cooking drink. Due to the pressure rise in the extractable product in the capsule, you can get a better extraction of the extracted product and, thus, the best drink. In particular, the beverage may contain more CO2that affects the foam layer on the prepared beverage. Also due to the pressure rise in the extracted product fluid to remain in the capsule, at the same time, for example, more flavour can be extracted from the extracted product, resulting in, for example, more tasty drink. The fluid can be fed into the capsule under pressure of approximately 12 bar (1200 kPa). Due to the flow resistance, in particular, the output layer can be obtained a pressure increase in the extractable product. The flow resistance, in particular, the output zone may be such that it prevents the through passage of the fluid until the pressure upstream from the target zone less for example, 4-5 bar (400-500 kPa).

With the creation of the output zones with flow resistance, greater resistance to the flow of the input area when the capsule is filled extractable product, the increase in pressure in the capsule can be more accurately reproduced, which may result in a more stable quality of coffee from one capsule to another. Under soprotivlenie to understand the flow resistance created by the fluid flow output (or input) layer in connection with the extractable product. The output layer with the extracted product creates a barrier or orifice for flow of fluid in the capsule to release from the capsules. The barrier thus created, is a measure for the flow resistance of the output layer with the extracted product. The flow resistance is generated by the output layer in cooperation with the extractable product in the output layer. Similarly, we can obtain the flow resistance of the input layer in cooperation with the extractable product.

Choke flow may be generated by the filter layer and/or layer filter in combination with grains extracted product, for example, when the grain is partially clog the pores and/or perforation channels of the filter. Depending on the grain size of the holes may have a size between about 0.2 mm and about 0.4 mm

Predpochtitel is but it is possible to obtain a uniform increase in the pressure in the extractable product in the capsule, thus creating better prepared drink. Stay hot water in the capsule for ekstragirovanija drink from the extracted product can be optimized and/or regulate. Longer extraction of the beverage can result in a better quality drink. The flow resistance of the output layer determines the possible increase in the pressure in the capsule before overcoming resistance to flow and the passage of aqueous fluid in the capsule through the output layer.

Approximately uniform increase in pressure in the capsule from the bottom to the closing element can give approximately uniform pressure drop. However, the pressure build-up may also be stepped, for example, with step differential pressure capsule. For example, when the pressure of the fluid constituting approximately 12 bar (1200 kPa), the pressure drop on the first part or parts of the capsule above the stream may be relatively small, for example, 0.5 bar (50 kPa). On the second part or parts of the capsule downstream differential pressure can be relatively large, for example, 6 bar (600 kPa). In the exit area of the capsule differential pressure may be, for example, approximately 5 bar (500 kPa). The pressure drop in the outlet area of the capsule can find the Xia between the output layer in the output area and the bearing surface of the socket or may be located between the output layer in the output area and these closing element by means of the socket. The pressure drop in the output area can contribute to the formation of a foam layer on cooked drink, for example, when the beverage is coffee cappuccino.

With the creation in the capsule of the flow resistance of the outlet area, when the capsule contains extractable product, larger than the input area when the capsule contains extractable product, you can ensure optimum build-up of pressure in the capsule and, thus, it is possible to obtain optimal extraction of the extracted product. So, you can get optimal brewed drink.

In the embodiment of the invention the input layer and/or the output layer capsule contains sheet perforated and/or porous layer. Perforation and/or porosity of the layer can be made with the possibility of creating an optimal resistance to flow. For example, the porosity of the input layer can be greater than the porosity of the output layer to obtain the flow resistance of the input layer more than the flow resistance of the output layer. Also perforation of the input layer can be larger than the perforations of the output layer or it may be more perforations in the input layer than in the output layer, to create the flow resistance of the input layer, the larger the flow resistance of the output layer. Combinations are also possible, so that the input layer can be formed as a perforated sheet, and you are the one layer may be made of a porous sheet or on the contrary. Also the input layer and/or the output layer can be a layer of perforated sheet and a porous sheet. Perforated sheet can also be porous and Vice versa.

In an embodiment, the input layer and/or the output layer capsule contains filter paper and/or polymer film with lots of holes, whereby the output layer contains, for example, less holes than the input layer. During the extraction, the paper layer and/or film layer remains intact. The cross section of the holes in the layer remains approximately constant during the extraction of the beverage. Openings shall not be moved apart or torn, or destroyed during use of the capsule in the device system. With the creation of, in particular, the output layer of filter paper and/or polymer film output layer can be strong enough to ensure that the pressure rise in the extractable product in the capsule to achieve the necessary pressure.

In an embodiment, the input layer and/or the output layer can be provided with many holes. Holes can be made so that the flow resistance of the input layer is less than the flow resistance of the output layer. For example, in the input layer can be created more holes than in the output layer. For example, the input layer can be provided with larger holes than echodnou layer. For example, the input layer may be provided with holes with a configuration different from the configuration of the holes in the output layer. Also the holes in the layer may have a tapered shape, for example conical shape. In the input layer of the hole can be smaller than in the output layer when, for example, narrowed in the direction of the flow.

In an embodiment, the flow resistance in the capsule increases from the bottom to the closing element. With the establishment of changing the flow resistance in the capsule pressure may increase in the capsule before the release of the prepared beverage from the capsule through the output layer. Preferably, the flow resistance of the output layer may be greater than the flow resistance in the capsule to ensure the growth pressure in the capsule, so that the pressure on the closing element may be less than the pressure at the bottom and, thus, to create a better brewed beverage with a longer contact time of the water /extracted product and the optimal and/or managed pressure. Changing the flow resistance and, thus, changing the contact time and pressure, the capsule can be fitted to create the best drink.

In an embodiment, the flow resistance in the capsule may depend on pressing the extracted product in the capsule. Pressing the extracted product can be such that soprotivlenie flow in the capsule increases the closing element, it is possible to obtain the pressure drop in the capsule. For example, the capsule contains extractable product in the form of roasted and ground coffee. Pressing can be changed depending on, for example, from grain size and/or characteristics of coffee, i.e. from strong coffee or soft taste or, for example, cappuccino or espresso. For example, for coffee with larger grain size, the degree of compaction may be less than for coffee with smaller grain size. For example, for coffee with a mild flavor degree of compaction may be different from the degree of compaction of strong coffee. For example, the size of coffee beans may be approximately between 0.2 and 0.4 mm, for example, 5 g of ground coffee in the capsule. The capsule may be filled between about 4-8 grams of roasted and ground coffee for the preparation of one Cup of the beverage, e.g., 30-200 ml drink, depending, e.g., grain size, degree of compaction, the characteristics of coffee (mild taste/ strong). Interchangeable capsule may be the package for one serving.

In an embodiment of the extracted product can be compressed into a tablet, in which the pressing is performed so that the flow resistance of the tablets increases the closing element. When using the pressed tablet of the extracted product, the input layer can be eliminated. The bottom has such clicks the zoom, the input zone, through which a certain amount of fluid can be served without the input layer. The output layer may be a layer of filter to prevent the extracted product from the capsule. The flow resistance of the output layer the closing element can then be greater than the flow resistance of the entrance area of the bottom. Also extractable product may contain a variety of tablets compressed extractable product, such as different pressing. Capsule near the closing element can have the greatest resistance to flow, for example, you may have the highest degree of pressing. In a preferred embodiment, the capsule may not have the input layer, and the consumer can fill capsule pills roasted and ground coffee. Preferably, the exchangeable capsule disposed of after use, but the capsule re-use is also possible. Capsule re-use the user can fill one or more tablets of roasted and ground coffee. Preferably, in the capsule re-use the input layer is eliminated, and the output layer is strong enough, so that washing is possible. For example, the capsule re-use can withstand washing in the dishwasher.

In the embodiment, the capsule may be nabeena additional sheet of porous and/or perforated layer, when this layer is made approximately parallel to the bottom and/or the closing element. With the creation of one or more additional layers in the capsule, the flow resistance in the capsule can be changed so that the flow resistance in the capsule increases from the bottom to the closing element and the pressure decreases from the bottom to the closing element. Preferably, the flow resistance of an additional layer in cooperation with the extractable product, the more resistance to flow in the input layer in cooperation with the extractable product and less than the flow resistance of the output layer in cooperation with the extractable product. This additional layer can be created, for example, in addition to or in combination with extruded extractable product. For example, the additional layers of the capsule can be divided into compartments. Thus, the compartments may, for example, to fill pressed extractable product, the degree of compaction which is different for each compartment. With the creation of additional layers and/or changeable by pressing the extracted product can be created optimum flow resistance in the capsule, which can be optimally adapted for a drink to be making.

In the embodiment, the peripheral wall of the capsule can be made from the fin is m to increase the resistance to flow from the bottom to the closing element. The edge may create a mechanical barrier to the flow of water in the capsule and may, therefore, increase the flow resistance, which increases pressure in the capsule to values that are optimal for cooking drink from the extracted product. For example, if the input pressure of approximately 12 bar (1200 kPa), the pressure in the capsule can grow to about 4-5 bar (400-500 kPa), depending on the extracted product and/or any drink. Additional differential pressure, for example up to 0.5 bar (50 kPa) may occur in the output area or between the output area and the supporting surface and/or connectors are closing element by means of the socket. Different types of the extracted product may require, for example, higher or lower optimal pressure for the beverage of good quality. The rib may be in the form of a wedge with the increase in the cross section of the closing element. Mechanical obstruction can also be constructed with truss elements passing between the bottom and the closing element, for example, with beam elements have an increasing cross-section of the closing element. Also, the peripheral wall can be created with a comb, passing in a direction approximately transverse peripheral wall. Preferably the ridges are to the penny what the capsules to create mechanical obstacles and, thus, increasing the flow resistance in the capsule.

Various combinations are possible to increase the flow resistance in the capsule from the bottom to the closing element. For example, additional perforated and/or porous layer can be created in combination with a mechanical obstacle, or in addition thereto, and/or extruded extractable product, and/or with an output layer with a certain flow resistance in combination with the extractable product in the output layer, which is preferably greater than the resistance to flow in the capsule, and/or with an input layer with a certain flow resistance in combination with the extractable product in the input layer, which is preferably less than the flow resistance in the capsule.

In the embodiment, the peripheral wall of the capsule is essentially rigid. The capsule may thus not be subject to deformation to use, so that the capsule may include receiving socket is relatively easy. Preferably, the capsule contains ribs, integral with the peripheral wall and/or bottom to increase the rigidity of the capsule. In a preferred embodiment, the ribs can also create a mechanical barrier fluid in the capsule, thus increasing the resistance to flow.

The invention also apply the to a capsule for preparing a specified number of drink.

The invention additionally relates to a method for making a specified number of drink.

The invention additionally relates to the use capsule for preparing a beverage using a system device.

The invention will now be additionally described using non-limiting examples with reference to the drawings, in which:

On Figa shows an example of the first variant execution system according to the invention.

On Fig.1b shows an example of the second variant execution system according to the invention.

On Figa 5b shows a variant example of implementation of the capsules according to the invention.

In the figures corresponding elements are indicated by corresponding positions. The figures shows non-limiting examples of the invention.

On figa shows an example of the first variant implementation of the system 1 for the preparation of a given amount of beverage suitable for consumption using the extracted product according to the invention. The system 1 includes a removable open capsule 2 and the device 4. The device 4 includes a receiving socket 6 for Ude is Jania exchangeable capsule 2. On figa shows the gap between the capsule 2 and the receiving socket 6 for clarity. It should be clear that when using the capsule 2 may be in contact with socket 6. In this example, the bracket 6 has a shape complementary with the shape of the capsule 2. In this example, the bracket 6 includes upper part 8 and the bearing surface 10.

The device 4 further comprises a device 12 for issuing a fluid medium that is designed to supply a quantity of fluid, such as hot water under high pressure, for example greater than approximately six bar (600 kPa) (absolute pressure), for example, 12 bar (1200 kPa), exchangeable capsule 2.

In the system 1 shown in figa, exchangeable capsule 2 contains essentially rigid peripheral wall 14, a bottom 16, the closing of the peripheral wall 14 from the first end 18, and a closing element 20 covering the peripheral wall 14 from the second end 22 opposite the bottom 16. Peripheral first wall 14, a bottom 16 and a closing element 20 limit the internal space 24 containing the extractable product, in this example, the roasted and ground coffee. In this example, the exchangeable capsule 2 contains some amount of extractable product, for example, approximately 4-8 grams of roasted and ground coffee, suitable for making single serving of drink, etc is doctitle, one Cup of the beverage, e.g., 30-200 ml of the prepared drink. Interchangeable capsule, thus, is a package for one serving.

In the example shown in figa, first peripheral wall 14 is substantially rigid. The peripheral wall 14 may, for example, consist of plastic and may be performed, for example, using injection molding, vacuum forming, thermoforming or the like

In this example, the bottom 16 is integral with the peripheral wall 14. In this example, the bottom 16 has a sheet shape and contains a multiplicity of holes 26 for securing the entrance of fluid into the capsule 2.

In this example, the closing element 20 has a sheet shape. Additionally, in this example, the closing element 20 is porous. The closing element 20 is in this example made of filter paper. In this example, the filter paper contains fibers of polyethylene. Other fibers and/or filaments, for example biorazlagaemykh or metallic thread, Auda possible. In this example, the closing element 20 is connected to the peripheral wall 14 termocline. In this example, the closing element 20 forms the farthest border of the capsule 2 in the direction of its axis. On figa shown that the closing element 20 rests on the supporting surface 10 of the socket . Many other embodiments of the filter layer are possible.

System 1 shown in figa, is operated as follows to prepare a Cup of coffee.

The capsule 2 is placed in the bracket 6. The closing element 20 rests on the supporting surface 10. Fluid here hot water under pressure, for example, 12 bar (1200 kPa), served in the extractable product in the inner space 24 through the inlet 26. Water should wet coffee grounds and extracted the necessary substances for the formation of a coffee drink. Coffee must be released from the capsule 2 through the porous sealing element 20. Coffee beverage is then released from the bracket 6 through many editions 28 and can be fed into the container 30, such as a Cup.

In the example shown in figa, the bottom 16 includes an input layer 32 with a multiplicity of holes 26, which are distributed essentially on the input layer 32. In this example, the input layer 25 forms the bottom 16. The input layer 32 has a flow resistance that is determined, for example, width, cross-section and/or distribution of inlet 26 to the input layer 32 and/or the material of the input layer 32 in combination with the extracted product. The flow resistance of the input layer is a property of the input layer in combination and/or in cooperation with EXT the state of Thuringia product. Extractable product in the vicinity of the input layer also determines the flow resistance of the entrance area.

In the example shown in figa, the closing element 20, which forms the exit area of the capsule 2 through which drink coffee here, can be produced from the capsule, contains the output layer 34. In this example, the output layer 34 forms the closing element 20. In this example, the output layer 34 is made of a porous sheet, such as filter paper. In this example, all of the closing element 20 is made as a porous sheet output layer 34. In this example, the closing element 20 forms an essentially continuous, permeable to the fluid sheet, covering essentially the entire second end 22 of the capsule 2. The output layer 34 has a flow resistance that is determined, for example, porosity and/or permeability of the filter paper. The flow resistance of the output layer is a property defined by the qualities of the output layer in cooperation with the extractable product near the output layer. Extractable product in the output layer in combination with the very output layer creates a barrier or choke flow, or the resistance of the fluid in the capsule to release from the capsules. After overcoming this barrier fluid medium in the capsule fluid passes through the output layer and l is moved from the capsule. This barrier is a measure of resistance to flow in the output area when the capsule is filled with the extracted product.

The flow resistance of the output layer 34 is higher than the flow resistance of the input layer 32, to ensure the growth pressure in the capsule 2 before the release of the beverage from the capsule 2 through the output layer 20. For example, if the hot water is supplied under pressure of approximately 12 bar (1200 kPa) and the pressure in the capsule can grow to approximately 4-5 bar (400-500 kPa). The pressure in the capsule 2 may be optimal for the cooking process and can give the best drink. Stay hot water in the capsule 2 for extraction of the beverage from the extracted product can become large for better extraction and, thus, as a result you can get a better drink. You can also prevent the build-up of pressure upstream from the capsules, which can damage the system 1 and/or is adverse to the cooking process. The input area may be a slight pressure drop (for example, 0.5 bar (50 kPa) in the first part (part upstream) capsules, and there may be additional small pressure drop (for example, 0.5 bar (50 kPa), which can be followed by a more significant pressure drop in the second part of the capsule (part of the lower flow), for example, 4-5 bar (400-500 kPa). In WMO is tion zone and/or after the input area may experience additional pressure drop (for example, 4-5 bar (400-500 kPa). Thus, it is possible to obtain the optimal increase pressure on the capsule for optimal extraction and cooking process.

On fig.1b shows an example of the second variant implementation of the system 1 according to the invention for the preparation of a given amount of beverage suitable for consumption using the extracted product. The system 1 includes a replaceable capsule 2 and the device 4. The device 4 includes a receiving socket 6 for holding the exchangeable capsule 2. In this example, the bracket 6 has a shape complementary with the shape of the capsule 2. On fig.1b shows the gap between the capsule 2 and the receiving socket 6 for clarity. It should be clear that when using the capsule 2 may be in contact with socket 6. The device 4 further comprises a device 12 for issuing a fluid medium that is designed to supply a quantity of fluid, such as water, under pressure to the exchangeable capsule 2.

In the system 1 shown in fig.1b, exchangeable capsule 2 has a peripheral wall 14, a bottom 16, the closing of the peripheral wall 14 from the first end 18, and a closing element 20 covering the peripheral wall 14 from the second end 22 opposite the bottom 16. The peripheral wall 14, a bottom 16 and a closing element 20 limit the internal space 24 containing the extracted product. In the data example exchangeable capsule 2 contains some amount of extractable product, suitable for making single serving of a beverage, preferably a single Cup of beverage, for example 30-200 ml of the prepared drink. Interchangeable capsule, thus, is a package for one serving.

In this embodiment, the bottom 16 includes an input layer 32 with inlet holes 26, the direction of the input layer 32, which are distributed essentially throughout the bottom 16. In the example shown in fig.1b, the bottom 16 is integral with the peripheral wall 14.

In this embodiment, the system 1 fig.1b contains connectors bottom tool 122 that is designed to pierce the capsule. On fig.1b connectors are shown the bottom of the tool 122 in the retracted position, that is designed to create an entrance hole in the bottom 16 of the capsule. However, here the bottom 16 of the capsule 2 is installed at a distance from these bottom means 122, so that the capsule 2 is not punctured connectors bottom means 122 and the bottom 16 remains intact when the connectors are the bottom of the tool 122 result in extended position.

On fig.1b connectors bottom tool 122 includes a channel 126 through which the fluid medium is supplied into the inner space of the socket 6. Fluid here hot water under pressure, for example greater than 6 bar (600 kPa), such as 12 bar (1200 kPa), must pass through the input layer 32 in the inner space 24 of the capsule 2 d is I the extraction of necessary substances from the extracted product, in this example, approximately 7 g of roasted and ground coffee for the preparation, in this example, one Cup of drink coffee here. The flow resistance of the input layer 32 can typically be quite low, so is the possible absence of a rise in pressure upstream from the input layer in the bracket 6 or channel 126, which can have a negative impact on the system 1 and/or drink.

In the example shown in fig.1b, the peripheral wall 14 is substantially rigid. The peripheral wall 14 may, for example, consist of plastic and may be performed, for example, using injection molding, vacuum forming, thermoforming or the like, or may be made of metal. Further, the system 1 shown in fig.1b may contain connectors are closing element means 128, designed to pierce the closing element alternative capsules. However, the closing element 20 capsules 2 contains the output layer 34, through which the drink can be released from the capsule 2. The output layer 34 is made having a sufficiently high tensile strength and/or tough enough to exclude perforation connectors are closing element by means 128 under the action of pressure inside the capsule 2. However, the output layer 34 can be deformed by these means p is on the pressure in the capsule, but must not be broken and/or torn, and/or pierce these means. The differential pressure capsule can give, as a result, the optimal extraction and/or cooking process. May occur the pressure difference between the output layer 34 and the connectors are closing element by means 128, which can be optimum for the formation of the foam layer on cooked drink.

In the example shown in fig.1b, output filter 34, which forms the exit area of the capsule 2 through which drink coffee here, you can release from the capsules made of a porous sheet, such as filter paper. In this example, the output filter 34 is installed in the output area of the closing element 20. Output filter 36 may form an essentially continuous, permeable to the fluid sheet, covering essentially the entire second end 22 of the capsule 2. Thus, the fluid can be released from the capsules 2 in a relatively large area.

The flow resistance of the output layer 34 is typically quite high, so that the increase in pressure in the capsule 2 may occur to increase the residence time of hot water in the capsule and/or increasing the pressure in the capsule. Preferably, the flow resistance of the output layer 34 more resistance to the flow of the input layer 32, so that the optimal pressure buildup can is to occur in the capsule 2 for the best extraction of the extracted product and better brewed beverage.

In addition to the relatively high flow resistance of the output layer 34 output layer 34 may also have a sufficiently high tensile strength and/or sufficient stiffness so that the output filter 34 is not deformed and/or broken, and/or connectors are not destroyed in the closing element of the tool. When the output of the filter 34, for example, made of filter paper, the parameters of the filter paper, such as material, density, thickness and/or the content of polyethylene, it is easy to choose to create an output filter having a sufficiently high tensile strength and/or forming a sufficient resistance to the flow. Alternatively, when the output of the filter 34, for example made of a polymer film containing a number of the outlet openings, the parameters of the polymer film, such as density, thickness, number of output holes, the size and/or shape of the outlet openings, you can easily choose to create a closing element 20 having sufficient tensile strength and/or forming a sufficient flow resistance. Alternative filter and/or the capsule can be made of metal or material may contain metal.

The parameters of the output layer 34 of the capsule 2 of the system 1 according to the invention can be chosen so that the output layer 34 has sufficient tensile strength and/or sufficient SOPs shall otulana stream to prevent perforation or rupture.

Figure 2 shows that the input layer 32 of the bottom 16 is integral with the peripheral wall 14. The input layer 32 contains a multiplicity of holes 26. Closing element 20 has an output layer 34 of the film, such as a polymeric film containing a number of the outlet openings 36. Capsule 2 contains protruding outside the rim 38, which are attached to the closing element 20, for example by gluing, welding, termocline or the like, an Output layer 34 may contain fewer holes than the input layer 32, so that the flow resistance of the output layer 34 more resistance to the flow of the input layer 32. Also attaching the output layer 34 to the rim 38 can withstand enough pressure. Additionally, the input layer 32 may, for example, be a single layer of filter that can be attached, for example, to serving inside the rim 42 (for example, shown in figure 3) bottom. Also the input layer and/or the output layer can be attached to the outside or the inside of the peripheral wall 14. Also the output layer can be integrated with peripheral wall.

In an embodiment, the flow resistance increases in the capsule from the bottom 16 to the closing element 20. For example, as shown in figure 3, the additional layer 40 may be created in the capsule 2. The additional layer 40 may be a sheet of porous or perforated layer, made approximately parallel with the input layer 32 and output layer 34. An extra layer according to figure 3 with openings 44. The flow resistance of the additional layer 40 is preferably greater than the resistance to flow in the input layer 32 and less than the flow resistance of the output layer 34. Therefore, the additional layer 40 may have fewer holes 44, the input layer 32, and to have more holes 44 than the output layer 34.

Also the flow resistance in the capsule 2 can be changed with the creation of the extracted product in pressed tablets 58, 60, 62 and 46, as shown in figure 4. Each of the tablets may have a different degree of compaction, and therefore the flow resistance of each tablet may be different. Preferably the tablet near the bottom 16 has a very low resistance to flow, and the tablet near the closing element 20 has the highest resistance to flow. Tablet 64 has a resistance to flow is greater than the pill 62, which has a resistance to the flow of more than 60 tablet. Tablet 58 has a lower flow resistance. The flow resistance can be changed on the tablet with a higher resistance to flow on one side and a lower resistance to flow on the opposite side.

The flow resistance of the output layer 34 is greater than the flow resistance of the tablets t is to the optimal pressure buildup, for example, the differential pressure can be obtained in the capsule for optimal extraction. The pressure can thus grow to a predetermined value, for example between about 4-10 bar (400-1000 kPa), preferably 5-6 bar (500-600 kPa). Then the flow resistance of the output layer 34 can be overcome, and the extracted product can be released from the capsule through the output layer 34 into the Cup 30, as shown in figa. To create a sufficient pressure drop in the capsule 2 because of the increasing resistance to flow from the bottom 16 to the closing element 20 the quality of the extracted beverage can improve. The development of increasing resistance to flow from the bottom to the closing element, the residence time of hot water in the capsule 2 can be increased, thereby also improving the quality of the extracted beverage. Additionally, creating a pressure drop at the exit zone and/or after the output zone, for example, between the output layer and connectors are closing element means you can get a foaming action.

Resistance to the flow of the extracted product in the capsule 2 depends on the grain size of the product, the degree of compaction of the product of the required quality of the drink and many other variables. For example, the capsule 2 contains roasted and ground coffee with pressing, providing led the increase in the flow resistance from the bottom to the closing element. Approximately capsule can be filled with 4-8 grams of roasted and ground coffee. The size of coffee beans, for example, be between 0.2 and 0.4 mm to approximately 5 g of ground coffee in the capsule 2.

On figa and fig.5b shows an embodiment of a capsule according to the invention, in which the flow resistance increases from the bottom to the closing element by mechanical means. Mechanical means in the embodiment shown in figa and fig.5b are ribs 46 in the form of a wedge. The cross section of the ribs 46 increases from the bottom 16 to the closing element 20 to create obstacles to the flow of water in the capsule 2 and, thus, increase the flow resistance to the closing element. May be made several ribs 46 may also be performed by other mechanical means of creating obstacles such as ridges extending from the peripheral wall inside the capsule.
