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 the extractable product, the bottom contains the entry zone, and the system is arranged to bring the device to issue the fluid in the message in a fluid environment with entrance area for supplying the fluid in the extractable product for preparing the beverage, and a closing element contains the output area, and the system contains the release, which, when used, reported by fluid output zone for the release of the prepared beverage from the capsule and supplying the beverage to a container such as a Cup.

This system using the capsule itself known. Capsule may be opened is the end, before using the outdoor into the surrounding atmosphere, although open capsule can contain, for example, in air-tight or gas-tight outer packaging. The open end of the capsule may be provided with a sheet of filter or other perforated and/or porous filter. Open the capsule may, for example, contain roasted and ground coffee in the quality of the extracted product. The capsule can be used to make a given quantity of coffee in a suitable device. A disadvantage of the known capsules is that the reproducibility of the drink may be unsatisfactory.

The objective of the invention is to improve the above mentioned systems and, more specifically, at least partial removal of the aforementioned problems.

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 designed to supply a given 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 period is aricescu wall from the second end, opposite the bottom, and the wall, the bottom and the closing element limiting the internal space containing the extractable product, the bottom contains the entry zone, and the system is arranged to bring the device to issue the fluid in the message by fluid input zone for feeding the fluid in the extractable product for preparing the beverage, thus closing element contains the output area, and the system contains the release, which, when used, reported by fluid output zone with the possibility of release of the prepared beverage from the capsule and supplying the beverage to a container such as a Cup, when this bracket is made with the possibility of release of the prepared beverage from the capsule through the output area output area of the capsule contains a layer of filter, where the filter layer contains a layer of non-woven and/or woven fibrous material, and a layer of filter contains at least one first region where the non-woven and/or woven material sealed to prevent liquid from passing through it, and at least one second region, where the non-woven and/or woven material not sealed to allow exit of fluid through it.

With the creation of a layer of non-woven and/or woven fibrous material from the first region, where the non-woven and/or woven material sealed, and Deuteronomy is the second region, where the nonwoven and/or woven material is not sealed, the second region may form a "hole" through which liquid can flow, having stable dimensions, I. e. the dimensions of the second areas should not change under the action of pressure fluid. Additionally, non-woven and/or woven material in the second regions may act as a filter, preventing grains of ground coffee from capsules. Sealing non-woven and/or woven material may be created by heating and/or melting non-woven and/or woven material locally, preferably only in the first regions. Other ways of sealing can be used, such as gluing, painting or impregnation resin in the first fields.

With the creation of a layer of non-woven and/or woven fibrous material, sealed in the first areas and unsealed second regions, the deformation and/or destruction of the second regions and, consequently, the openings through which fluid can pass, can be prevented. To prevent deformation and/or fracture of second areas, the pressure in the capsule can be more accurately reproducible from one capsule to another. Also the quality of the drink may become approximately constant from capsule to capsule. A drink made with caps the crystals, according to the invention can have superior quality and can be more accurately reproducible from one capsule to another.

With the creation of the input area at the bottom with a layer of filter, where the filter layer contains a layer of non-woven and/or woven material, and a layer of filter contains at least one first zone, where the non-woven and/or woven material sealed to prevent liquid from passing through it, and at least one second region, where the non-woven and/or woven material not sealed to allow exit of fluid through it, also the layer of the input filter can improve the reproducibility of pressure rise in the capsule. Also create a filter in the input area you can prevent spilling of the extracted product from the capsule at the bottom, for example, due to high pressure. With the creation of the input filter of the layer of non-woven and/or woven fibrous material with the first and second regions can be created stable entrance area with a reliable and repeatable build-up of pressure in the capsule. The throttling of the fluid flow, you can create a layer of nonwoven and/or woven fibrous material of the filter.

Under the non-woven fibrous material see material containing fibers and/or filaments, which may be relatively long and/or relatively short, positioning the situations is very chaotic in the material. The preferred orientation of the fibers and/or filaments and/or location and/or organization of the fibers and/or filaments in the material is missing. An example of a non-woven fibrous material is Tyvek®.

Such paper material can be considered as non-woven material containing fibers chaotic unpredictable location.

Under woven fibrous material see material containing fibers and/or filaments, which may be relatively long and/or relatively short. Fibers and/or filaments are woven. Well-known woven material may include fibers and/or strands running in the first direction across the fibers and/or strands running in the second direction, for example, transverse to the first direction. Knitted fibrous material in the context of this invention be considered as a woven material.

The filter layers from both nonwoven and woven fibrous material are preferred elastic properties, i.e. they are relatively inelastic in the plane of the layer filter. In the plane of the layer, the filter layer may too not be stretched, so that the holes in the layer can be approximately undeformed, for example, under the action of the voltage from the pressure in the capsule.

In the embodiment, the nonwoven and/or woven material contains polymerisation, such as polypropylene or polyethylene fibers. With the creation of the polymeric fibers of the nonwoven and/or woven filter layer may become less sensitive to deformations due to the pressure of the fluid. Also, non-woven and/or woven material may contain biorazlagaemykh fibers, such as paper fibers. The walls of the capsules may, for example, be made of biorazlagaemykh material, with byroslawsky filter capsule can be biodegradable. After use, the user can throw bioresource capsule, for example, in a special bin. In another embodiment, the wall of the capsule and/or the input layer and/or the output layer can be constructed from plastics, recyclable. Filter layer of non-woven and/or woven material may also be subject to secondary processing. In another embodiment, the wall of the capsule and/or the input layer and/or the output layer can be created from metal, for example, capsules re-use, for example, when the capsule can repopulate the user. Non-woven and/or woven filter layer and/or the capsule can be created from a fibrous material suitable for washing in the dishwasher.

In the embodiment, the filter layer is a multilayer filter, with the additional layer containing a series of, an additional layer is perforated and/or porous layer. With the creation of an additional layer of non-woven and/or woven filter layer may become stronger and more resistant to high pressure fluid. With the creation of an additional layer with perforations and/or porosity fluid can pass through the layer of filter in the output and/or input area. Preferably the layers are linked together to give each other additional strength and/or stiffness.

In an additional embodiment, the additional layers can consist of a nonwoven and/or woven material, the filter layer may be a multilayer filter, a relatively simple and economical. Preferably the layers are linked together to give each other additional strength and/or stiffness. Preferably the layers are linked to each other about all the first regions. Preferably the second region largely overlapping multiple layers to provide passage for the fluid medium.

The second region of the layer of the filter, where the non-woven and/or woven material not sealed, to ensure that the flow through them can be distributed essentially over the entire surface layer of the filter. Distribution of "holes" essentially over the entire surface layer of the filter can be achieved approximately evenly the pressure distribution over the layer filter to ensure approximately uniform pressure rise in the entrance area of the capsule. Perhaps the concentration of holes in the Central zone of the filter layer and leaving the peripheral edge of the filter layer free from holes.

In a preferred embodiment, the holes and/or the perforation tunnels additional layer correspond to the second areas of the layer of non-woven and/or woven material to ensure passage of fluid through them.

In the embodiment, the bracket includes connectors bottom of the tool that is designed to pierce the input zone alternative capsule for creating at least one inlet port for supplying a fluid medium in the extractable product through at least one inlet opening. The capsule system according to the invention is made so that the entrance area of the capsule contains input filter for supplying a fluid medium in the extractable product through him, the input filter is set at a distance from these bottom means, so that the capsule system is not punctured connectors bottom of the tool and the bottom is not damaged.

In an additional embodiment, the bracket includes connectors are closing element of a vehicle designed to pierce the output zone alternative capsules when the output area is sufficiently pressed against these closing element environments the TSS under the action of pressure fluid and/or beverage in the capsule for creating at least one outlet opening, through which the beverage can be produced from alternative capsules. The capsule system according to the invention is made so that the output area of the capsule system includes an output filter, through which the drink can be released from the capsule of the system, with these closing element means and an output filter adapted to each other so that the capsule of the system when using non-pierced connectors are closing element means and the closing element is not damaged.

Additional preferred embodiments of the can be found in the dependent claims.

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

In Fig.1 shows an embodiment of the system according to the invention.

In Fig.2 shows a first embodiment of a capsule according to the invention.

In Fig.3 shows a second embodiment of a capsule according to the invention.

In Fig.4 shows an embodiment of the nonwoven material layer filter according to the invention.

In this description, identical or corresponding elements are indicated identical or corresponding reference positions. Examples of embodiments should be considered non-limiting and serving only as an illustration.

In Fig.1 shows an example of option execution 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 104. The device 104 includes a receiving socket 106 to hold the shift of the Noah capsule 2. In this example, the bracket 106 has a shape complementary to the shape of the capsule 2. In Fig.1 shows the gap between the capsule 2 and the receiving socket 106 for clarity. It should be clear that when using the capsule 2 may be in contact with socket 106. The device 104 further comprises a device 108 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.1, the exchangeable capsule 2 has a peripheral wall 10, a bottom 12, end of the peripheral wall 10 from the first end 14, and a closing element 16, the closing of the peripheral wall 10 from the second end 18 opposite to the bottom 12. The peripheral wall 10, a bottom 12 and a closing element 16 limit the internal space 20, containing the extracted product. In this example, the exchangeable capsule 2 contains the number of the extracted product, suitable for making single serving of a beverage, preferably a single Cup of the beverage, e.g., 30-200 ml of the prepared drink. Interchangeable capsule, thus, a package for one serving. Extractable product may, for example, be roasted and freshly ground coffee.

System 1 shown in Fig.1, contains connectors bottom tool 122 that is designed to pierce alternative the second capsule. In Fig.1 shows the connectors bottom of the tool in its extended position, is designed to create an entrance hole in the bottom of an alternative capsule.

In Fig.1 these means 122 includes a channel 126 through which the fluid medium is supplied into the inner space of the socket 106. Fluid here hot water under pressure, for example, more than four bar (400 kPa), for example, twelve bar (1200 kPa), must pass through the input filter 34 in the inner space 20 of the capsule 2 for the extraction of necessary substances from the extracted product, in this example approximately 4-8 grams of roasted and ground coffee for the preparation in this example, one Cup of drink coffee here. The fluid can be fed under pressure between 4 and 20 bar (400-2000 kPa), preferably between 4.5 and 18 bar (450-1800 kPa), and more preferably between 5 and 15 bar (500-1500 kPa). Depending on compaction, grain size and/or the desired character of the drink between 4 and 10 grams of the extracted product can be contained in the capsule 2.

Thus, more generally, in the example of Fig.1, the bottom 12 includes an input area, and the system 1 is arranged to make the device 108 for issuing a fluid medium in a message on fluid input zone for feeding the fluid in the extractable product for preparing the beverage.

In the example it is shown in Fig.1, the peripheral wall 10 is substantially rigid. The peripheral wall may, for example, consist of plastic and may be performed, for example, using injection molding, vacuum forming, thermoforming or so on, Also in the example shown in Fig.1, the peripheral wall 10 forms a truncated cone, but other forms are also possible. For example, the peripheral wall may be cylindrical, or pyramidal or hemispherical or polygonal, such as hexagonal or octagonal.

In the example shown in Fig.1, the bottom 12 is integral with the peripheral wall. Thus, fluid is served in the extractable product through the inlet region, which leads to wetting of the extracted product essentially over the whole cross section of the capsule 2. Thus, it is possible to obtain a satisfactorily homogeneous flow of the fluid in the extracted product.

Additionally, the system 1 shown in Fig.1, contains connectors are closing element means 128, designed to pierce the closing element alternative capsules when the closing element is sufficiently pressed against these closing element means 128 under the action of pressure fluid and/or beverage in an alternative capsule for creating at least one is on the outlet, through which the beverage can be produced from alternative capsules of the prior art.

According to the invention the capsule 2 contains the output area through which the drink can be released from the capsule 2. According to the invention the output area contains the output filter 36. Output filter 36 may be a layer of filter containing a layer of non-woven and/or woven fibrous material, with a layer of filter contains at least one first region where the non-woven and/or woven material sealed to prevent liquid from passing through it, and at least one second region, where the non-woven and/or woven material not sealed to ensure the flow through it. Under the action of pressure inside the capsule 2 output filter 36 can be deformed in these closing element of a vehicle, but may not be broken, not to collapse or not to pierce connectors are closing element means. In another embodiment, the output filter 36 may not be deformed under the action of pressure of fluid in the capsule, so that the size of the second regions remain approximately unchanged, I. e. with less than 3% deviation during use. Thanks nonwoven and/or woven material, you can create a stable output filter 36, which may remain intact under the action of pressure. DOS is enough pressure can build up in the capsule 2 to obtain a good quality drink. In addition, due to the non-woven and/or woven layer output filter can be strong enough and rigid enough, the pressure buildup can be reproduced from one capsule to another, which improves the reproducibility of the brewed beverage.

Alternative or additionally, the output filter 36 adapted to these closing element means 128 so that the capsule 2 when using non-pierced connectors are closing element by means 128 and the closing element 16 is not damaged. In more General terms, this means that the output of the filter 36 and connectors are closing element means 128 are adapted to each other so that the capsule 2 when using non-pierced connectors are closing element by means 128 and the closing element 16 is not damaged.

In the example shown in Fig.1, these closing means 128 is shown with sharp jagged peaks, designed to pierce the closing element. It should be clear that, alternatively, these closing means 128 may have a blunt connectors surface, such as shown by dashed lines in Fig.1. However, in this alternative embodiment, the capsule can be pierced stupid these means 128, for example, when the close is that element of an alternative capsule consists of a sheet of aluminum foil. Parameters such as the presence of non-woven and/or woven material, distribution and/or the presence of a plurality of first and second regions, the stiffness and/or strength of the output filter capsules 2 system according to the invention can be chosen so that the output of the filter 36 may not pierce or not to break. It should be clear that when the connectors are closing element of the tool is blunt, the parameters of the output filter can be selected suitable for this these tools. When these tool is dull, the output filter can for example, be thinner than when connectors are closing element of the tool is sharp, while ensuring that the output filter has a sufficiently high tensile strength and/or a sufficiently low flow resistance so as not to pierce or not to break. These closing means may include ridges, on which the closing element when using rests. Such ridges can be formed stupid these means 128, as shown in dotted lines in Fig.1. Combs can, for example, to form at least 10%, probably at least 25% of the surface area of the socket 106 that, when used in the same area on the surface of the closing element 16, overlying the second to the end 18. Thus, when using the closing element 16 can rely on ridges, for example, for at least 10%, preferably at least 25% of the plot area of the surface of the closing element 16, overlying the second open end 18. As already mentioned, the closing element alternative capsules can pierce these ridges, and the parameters of the output filter 36 capsules 2 system 1 according to the invention can easily be chosen so that the output filter has a sufficiently high tensile strength and/or sufficient stiffness so as not to pierce or not to break. The output filter can be rigid and/or rigid enough such that the output filter is based on the top surfaces of the ridges and is not deformed by moving to the bottom between the ridges. Deformation of the output of the filter is thus limited. It should be clear that when the connectors are closing element means includes ridges, the parameters of the output filter can be selected corresponding to such connectors are closing element of the tool.

In the example shown in Fig.1, the combs contain edges that are not sharp. In this example, the radius of curvature of the edges is approximately 50 μm, although there may be other acceptable radii, such as 100, 200 or 500 μm. Alternativnaya according to the prior art may, however, to pierce blunt these means 128, for example, when the closing element consists of a sheet of aluminum foil. It should be clear that when the connectors are closing element tool contains mild edge, the parameters of the output filter 36 can choose appropriate such connectors are closing element of the tool. The layer settings of the output of filter 36 capsules 2 system according to the invention can be chosen so that the output of the filter 36 may not pierce or not to break.

It is also possible crests connectors are closing element means 128 with a convex top, on which the closing element 16 rests. In this case, when the closing element when using pressed against the ridges, the surface region, which closing element rests on the crests increases, this decreases the local pressure exerted on the closing element crests. Thus, it can be a simple way to ensure that the closing element when the use is not terminated and/or is not destroyed and is not damaged.

In the example shown in Fig.1, the output filter 36, which forms the output region of the capsule 2 through which drink coffee here, you can release from the capsules, made in the form of a layer of a filter of non-woven and/or woven material, such as filtroil the second paper, containing at least one first region where the non-woven and/or woven material sealed to prevent liquid from passing through it, and at least one second region, where the non-woven and/or woven material not sealed to ensure the flow through it. Non-woven and/or woven material may include polymer fibers, such as polypropylene or polyethylene fibers. Non-woven and/or woven material may also contain biorazlagaemykh materials, such as paper fibers.

In embodiments, the implementation shown here, the entire closing element 16 is designed as an output filter 36. Thus, the fluid can be released from the capsule 2 over a substantial area. Thus, it can be obtained satisfactorily homogeneous production of the beverage from the extracted product.

In the example shown in Fig.1 capsule 2 contains protruding outside the rim 38 at the second end 18, thus closing element 16 is attached to the protruding outward of the rim 38, for example, an adhesive connection, or welding, etc., In the example shown in Fig.2 and Fig.3, the output of the filter 36 is attached to the protruding outward of the rim 38.

In the example shown in Fig.1, the input area is open to ensure the passage of liquid through it into the capsule 2. In the example shown in Fig.2, the input area of the bottom 12 is nabeena input filter 34. According to the aspect of the invention, the input filter 34 includes a filter layer, the filter layer is a layer of non-woven and/or woven fibrous material, and a layer of filter contains at least one first region where the non-woven and/or woven material sealed to prevent liquid from passing through it, and at least one second region, where the non-woven and/or woven material not sealed to ensure the flow through it. According to the aspect of the invention, the capsule 2 contains input filter 34 mounted at a distance from these bottom means 12, so that the capsule 2 is not punctured connectors bottom means 122, and the bottom 12 is not damaged when the connectors are the bottom of the tool is in the extended position.

In the example shown in Fig.2, the input filter 34 is created in the form of bottom 12. In the example shown in Fig.3, the input filter 34 is created in the form of a separate layer of the filter attached to the speakers inside the edges 42 of the bottom 12. The input layer of the filter 34 may also be attached to the inner or outer surface of the peripheral wall 10, and/or to the inner or outer surface of the projecting inward of the edges 42 of the bottom 12.

In General, the parameters of the output filter layers 36 capsules 2 system 1 according to the invention it is possible to choose such that the output filter is not what was Srivasa or not destroyed, for example, have relatively high tensile strength and/or a sufficiently high rigidity and/or created a fairly low resistance to flow, so as not to pierce or not to break. It should be clear that the closing element and/or output filter can not break or not to break these closing element by means 128. When the output of the filter 36, for example, made of partially compacted filter paper, the parameters of the filter paper, such as density, thickness and/or the content of polyethylene, distribution and/or the combination of the first and second areas can easily choose to create an output filter with a sufficiently high tear strength and/or with a sufficiently low flow resistance. In Fig.4 in the embodiment shown nonwoven filter layer containing the first region 51 where the non-woven material is sealed, and the second region 52, where the nonwoven material is not sealed. The second region 52 are thus open to ensure the flow through them. The fibers in the nonwoven material are chaotic and have no preferred orientation or location. The throttling of the fluid flow creates a non-woven filter layer. Non-woven filter layer usually contains a number of threads and/or fibers, as shown in Fig.4. Threads can have different length and R is lichnye diameters and can be created from various materials.

The first area of the non-woven filter layer can be sealed, for example, by gluing, colouring, melting or impregnated with resin. The second zone is left open or can be made public and are not sealed. Depending on the method of execution of the second regions, the second region can be completely open, for example, when the second region to perform hot or cold needle, or filaments and/or fibers of the nonwoven layer of the filter may still be present in the second areas, but in this case, for example, without resin between threads.

Preferably, the second zone is not deformed, not broken or does not collapse under the action of pressure fluid. The second region can be reinforced on the edges to prevent deformation, rupture or fracture of the second regions. Edges can, for example, reinforced with extra glue and/or paint, or thermal fusion of the edges. The second region can be distributed approximately evenly around the entire surface of the filter layer, or the second region can be created with various designs. The second region can be distributed randomly around the entire surface of the filter layer. The second region may have different sizes. Preferably the size of the second region is smaller than most grains extrage the product has been created in the capsule to ensure separation of the extracted product in the capsule and does not minimize the passage of grain through the second region.

Input and/or output filter can be made in the form of a multilayer filter layer nonwoven and/or woven fibrous material. Preferably the layers are linked together to create a stable filter. Stable filter can provide sufficient increase in the pressure in the capsule and may be rigid and/or rigid, so as not to pierce or not to break the closing element or connectors bottom of the tool. The filter layer may be rigid and/or rigid to prevent deformation and/or destruction of the second regions. Preferably the first and second region of one layer of filter refer to the first and second areas, respectively, of an additional layer of filter to ensure the passage of fluid through the corresponding second region.
