The invention relates to a capsule containing nutritional ingredients for acepting cooking a food product by mixing the ingredients with the liquid. Capsule contains the filter for removal from the fed in the capsule liquid foreign components. More specifically, the invention relates to a capsule that is inserted in the dispensing of fluid into the capsule for preparing a food product, such as baby food, product for teenagers or product for adults, by mixing the liquid with food ingredients. The invention also relates to a method of cooking a food product by use of such capsules.

Food mixtures can be, for example, baby food and liquid food for toddlers, the disabled, the elderly, persons suffering from eating disorders, or athletes. Such mixtures are prepared from capsules ingredients by adding a liquid such as water. In water may contain undesirable impurities, such as microorganisms and/or particulates (e.g., dust, minerals, organic residue, etc.). Such undesirable impurities must be removed from the fluid before mixing with the ingredients to ensure acepting and safe preparation of the mixture.

Thus, creatures�exists a need in the capsule which would prepare nutrient mixture, such as baby food or other food mixtures, convenient and secure way.

In document WO 2006/077259 discloses a method for preparing a single serving of the food mixture, providing for flow of fluid, for example water, into the cartridge containing one serving of the mixture in concentrated form. The water is treated before being fed into the cartridge to remove pathogenic microbes present in water. Treatment can be performed, for example, by pre-heating, filtration or irradiation of water with ultraviolet radiation.

Document WO 2008/012314 relates to a device allowing to carry through filtering processing water used for cooking food mixtures using capsules that are inserted into the dispenser.

Document WO 2009/115475 relates to a capsule for preparing a liquid with pierce to release the wall.

In documents WO 2009/092629 and EP 2009156782 described capsule with built-in antibacterial filter.

Preferably the antibacterial filter is a thin microporous membrane that requires exceptional precautions when handling it and when you install it in the capsule during the manufacturing process. When dealing with the filter must also comply with the measures predeterminately prevent premature contamination. In addition, it is necessary to ensure correct installation and connection of the filter in the capsule to avoid possible damage to the filter during the preparation of beverages. Manipulation of the filter can be simplified at the expense of industrial production, which will ensure high quality and compliance with strict sanitary requirements.

In addition, there is also a need to optimize the use of packaging (i.e. non-food) materials in the capsule, without compromising the ability of the capsule to withstand being created in it a high pressure liquid, and also preferably to get more eco-friendly product with lower price.

Another requirement is to ensure the release of a predefined quantity of the food mixture, which is in a capsule to obtain from each capsule full serving, for example, for a baby or child. In capsule should not remain a large number of food mixtures, and most preferably, the liquid and solid substances must be fully discharged from the capsule. However, the filter capsule can create too much resistance for compressed gas (e.g. compressed air) supplied to the capsule during the phase of unloading. As a result, the gas pressure may be insufficient to fully unload the capsule, or would require too� high pressure gas, which will increase the complexity and cost of the system.

Another requirement is to exclude during unloading capsules interaction between the firing device for purging gas and contaminated liquid, such as food ingredients or liquid, otherwise, may require systematic cleaning and, consequently, the system using a self-cleaning system, which will complicate the design of the device.

Another requirement is to prevent deformation of the filter as a result of pressure supplied to the capsule of fluid, in particular the pressure at the front on the flow surface of the filter.

One or more of the above requirements are satisfied in the present invention are characterized in the attached claims.

In particular, in a capsule for preparing a food product in a device adapted to dispense in a capsule liquid containing at least one compartment with food ingredients for cooking a food product by mixing with the feed fluid and filter designed for removal contained in a fluid contamination, according to the present invention, the filter is made in the form of filtering devices consisting of a filter membrane and an outlet wall that supports the f�Strouma membrane, in the exhaust wall is made of at least one outlet for fluid communication with said compartment.

Preferably the outlet opening for fluid axially displaced relative to the filter surface of the filter membrane.

Preferably, the filter device is axially displaced relative to the compartment.

Preferably, the capsule comprises a body bounding a compartment for ingredients, and the seat under the filter, which preferably is located at the side of the compartment.

Preferably, the filtration device is relatively rigid.

Preferably, the filter device includes a relatively rigid casing inside which there is a filtering membrane. This can simplify the manufacture of the capsule and make it more aseptico, which eliminates contact with the filter membrane.

Preferably, the casing is pressure-resistant and manipulated.

In this case, the term "manipulated", it is understood that the filter device is a node that can keep and perform the manipulation, for example, during manufacture of the capsule, without exposing the filter membrane external influences and mechanical constraints of the enclosure.

Preferably filtration is microporous.

In particular, the filter device includes an inlet wall forming together with the exhaust wall of the internal chamber into which the filter membrane, which is additionally sealed along the edge attached to the shroud.

Such covering design provides reliable protection filter membrane during manufacture of the capsule, and during the preparation of a liquid food mixture.

The filter housing fit at least partially perceives clamping and sealing force generated by the dispensing of the fluid, which affect the capsule, thereby selecting the load from the filter membrane and preventing its rupture and damage.

Preferably, the casing of the filter fixture consists of two halves folded together. The filter membrane may be pressed and/or welded on edge to the casing, for example, when connecting the two halves. Halves can be plastic parts, connected by using a click and/or ultrasonic welding. Such elements are sufficiently rigid and resistant to bending under pressure injected into the capsule liquid. Such elements are made from food grade polymers, for example polypropylene, polyamide, polyethylene, polyamide/polypropylene, PVC, polystyrene, polyetheretherketone, �olivacea acid, materials based on starch or metal, such as aluminum, and combinations thereof.

Preferably the outlet wall has a relief structure comprising, for example, of the plurality of protrusions or spines, between which can pass the filtered liquid. According to one embodiments of the invention the microporous membrane can rest his bottom outlet on the mentioned surface relief structure, protruding into the inside of the casing of the filtering devices and distributed over the surface of the microporous membrane. Such a relief structure ensures minimum deviation of the filter membrane under the action of fluid pressure, and promotes the collection passed through the membrane fluid at the outlet of the filter housing adaptations for feeding in the compartment of the capsule. According to another embodiment, the relief structure supports the top membrane of the capsule, thus preventing it from breaking and cutting off the fluid flow at the outlet walls of the filtering device.

In an inlet wall of the casing has at least one inlet opening for the liquid. In this hole is at least one resistant to perforation of the septum, transversely intersecting the axis of the inlet �TVersity to prevent piercing of the microporous membrane external perforating device, not part of the capsule. The barrier may be located transversely part, located at the inlet of the casing of the filter device, and to form part of the inlet wall of the housing. The size (e.g., width and thickness) and shape of the partition may be different.

Preferably the cross-section of the filtering devices is less than the cross section of the compartment containing the ingredients. Most preferably the cross-section of the filtering devices is at least two times smaller than the cross section of the compartment. One advantage of this is the ability to reduce the size of the filter septum in its Central part. Another advantage is to reduce the amount of packaging material used for manufacturing the filter device and, ultimately, improving its environmental performance and reducing the cost of production.

The capsule can also comprise a housing, for example, in the form of a Cup in which to place the ingredients (e.g., baby food). The body of the capsule limits the first compartment and located at the stream in front of him the seat under the filter, which is placed in the filter device. The seat under the filter allows you to easily insert the filter fixture during Assembly of the capsule on the production�dstvennogo line. Also can be considerably reduced with the number of elements of the capsule. The frame may be made of molded plastic, for example, using injection molding or thermoforming.

The seat under the filter can be offset from the center of the first compartment in the transverse direction. Due to the displacement of the seat under the filter from the centre of the filtering device can be moved relative to the compartment to the side wall of the capsule, which allows you to connect it to the feeder fluid, it becomes less susceptible to deformation as a result of fluid pressure.

Preferably along the seat under the filter passes planteary ring, which is uninterrupted continuation lanzoprazole rim, passing around the compartment.

In particular, the filter device has an outlet nozzle extending from offset seats for the filter in the direction of the first compartment and over him. The exhaust nozzle includes one or at least a limited number of outlet holes of small diameter, creating in the compartment is a solid stream of fluid. Preferably, the nozzle includes a single outlet with a diameter of 1.0 mm, most preferably from 0.2 to 0.7 mm. Outlet can create a jet of fluid with velocity u�current from 1 to 20 m/sec. Generated by the jet nozzle creates in the compartment turbulence that effectively dissolves and/or diffuses all the ingredients in the liquid.

The capsule also has openable inlet for gas that does not pass through the filter membrane and connects the inner space of the first compartment with the space outside of the capsule. Preferably openable inlet for gas is made in a filtering device, for example in the intake wall, and communicates with the exhaust nozzle. The inlet for gas to supply the compressed gas to remove the capsule from the fluid, thereby facilitating withdrawal from the capsule all of its content. Inlet gas can be opened by piercing or punching parts of the capsule. Since the inlet for gas communicates with the output side of the filtering device, i.e. with a channel leading to the nozzle, the forward element of the device for liquid supply, which was done, the inlet port for the gas only comes into contact with the filtered fluid.

In particular, the total upper membrane hermetically attached to the compartment and a filtering device. The membrane is sealingly attached in such a way that it is individually closes the inlet for liquid and an inlet opening for ha�and. Due to this, the inlet port for the fluid can be accomplished, for example, by punching device for the injection of liquid, whereas the inlet opening for the gas is closed by a membrane. Inlet gas can selectively be opened, for example by tearing the membrane to the gas-tight membrane, in particular by the insertion of needle or tube into the intake hole for gas.

Preferably the capsule according to the invention there is a system of release of the liquid product, located on the stream after the first compartment that can be opened and closed before installation in the feeder fluid. The exhaust system of the liquid product can be configured to create a fluid pressure (e.g., from 2 to 10 bar) in the compartment, which contributes to the dissolution or the distribution of ingredients in the injected fluid.

For example, the system of release of the liquid product can be one of the following elements:

- puncked or breaking the wall,

- the combination of puncked wall and at least one perforating element,

- the valve contains at least one hole or slit opening under pressure,

- a filtering wall with a pre-done holes for the Department facing Zhidkov� product from the solid particles, located in the compartment.

Contained in the compartment food ingredients can be in the form of a liquid concentrate, paste, gel, powder, or combinations thereof.

Preferably food ingredients represent a baby food, ingredients based on milk, cooking the mixture, or any other relevant foods containing proteins, lipids, carbohydrates, minerals, fiber, and combinations thereof.

The object of the invention is also a filter node that contains a filter membrane and an outlet wall that supports the filter membrane, wherein the outlet wall has an inlet for fluid and an exhaust nozzle with at least one outlet opening for a fluid, wherein the filter unit is made as a fixture placed on the stream in front of the compartment of the capsule with the ingredients for cooking a food product, the nozzle is directed inside the mentioned compartment. According to one embodiments of the invention the outlet opening for fluid filtering devices is shifted such that it is located outside the axial projection of the filtering surface of the filtering membrane.

All the described parameters of the filter device in this case also apply to the filtering node. For example, the filter node preferably ODS�REIT resistant to pressure, manipulated, relatively rigid casing with inlet and outlet holes. More preferably, the node contains the inlet for gas, intended for the discharge of the liquid contents of the capsule, which is located separate from the inlet for fluid and which does not pass through the filter membrane. In the filter node may also have a separate outlet for gas, or, alternatively, the outlet gas can be combined with the outlet opening for the fluid nozzle.

The invention is illustrated by drawings, which show preferred variants of its implementation.

Capsule 1A consists of a housing 2, in which food ingredients are filtration devices and systems for product release. Capsule body made in the form of the Cup 3, which is closed with a waterproof upper membrane or foil 4, is hermetically attached to lanzoprazole the rim 5 of the housing. The membrane 4 can only be water resistant, or, most preferably, moisture - and gas-tight. In particular, the membrane may be a multilayer comprising a gas-tight layer, for example, of a copolymer of ethylene with vinyl alcohol (EVOH) and/or aluminum. As will be discussed more fully hereinafter, the upper membrane is made of puncture resistant material, for example of thin polymer and/or aluminium, allowing, on the one hand, to be served in a capsule of fluid through the nozzle 6 for the liquid, and on the other hand, feeding the gas through a nozzle 7 for gas.

At the bottom 8 of the Cup 3 is made the outlet opening 9 that is designed to discharge liquid from the capsule mixtures of food/product. The outlet opening 9 for the product may consist of one or more openings through which liquid under pressure passes in the direction of the receiving containers, such as bottles, baby food, cups or mugs. The outlet opening 9 for the product can pass from the bottom of the Cup in the form of short�ow tube 10, directing the fluid flow and prevent splashing of liquid that can stain the space around the mug.

In the upper part of the capsule housing has a protrusion 11 which is placed in a filter for filtering the supplied to the capsule liquid. As shown in Fig.2, the capsule may be further provided with a three position code element 12 that can communicate with a positioning sensors of the device for supplying the fluid to determine the type inserted into the dispensing capsule to be identified for a capsule type, you could select a particular cooking cycle, for example by supplying adequate amounts of water, choice of temperature, flow rate, etc.

As shown in Fig.4 and 5, in the Cup of the capsule has a compartment 13 formed by the bottom and the side wall of the Cup 3, which are food ingredients 14. The volume of the compartment may be different, depending on the volume injected into the liquid. Overall, for a large volume of liquid, it is preferable to use a large amount to compartment acted as containers for mixing ingredients and liquid and formation of the composition.

The capsule may be provided with a system of 15 product release, providing the appropriate interaction between the feed liquid and ingredients, inside compartments personalized colors�and capsules and reduce or preferably prevent the interaction between food mixture and device. According to one embodiments of the invention, the system of release of the product is designed in such a way that it was done at least one outlet in the capsule for release of the mixture after you create inside the compartment sufficient fluid pressure. To do this, at the bottom 8 of the Cup in some places there are perforating elements 16 arranged so that they perforated the lower membrane 17, which normally separates the compartment 13 from the nozzle 9 for the liquid product. The lower membrane is usually thin waterproof puncked membrane, made of aluminum and/or polymer. The membrane is sealingly attached to the lower edge of the Cup. For example, the membrane is a 30 micron aluminium foil. Capsule containing a system of release of the product described in document PCT/ER/053033. It should be noted that the system of release of the product and may have other structure. In particular, it may be a conventional valve, consisting of holes or slits are normally closed and are opened under the action of the pressure generated in the compartment as a result of the feed in the liquid. Alternatively, it can also be porous wall is used for filtering the product.

In addition, the capsule according to the invention is designed so that it provides filtering of the supplied fluid in the compartment. The need for filtering fluid supplied essentially associated with the need to maintain high quality liquid, for example water added to the composition prepared. Water can be supplied with an operating temperature of, for example 35-40°C, due to the heating of room temperature water supplied from a water tank or feed fluid. More preferably, the filter for removing contaminants, including microorganisms, such as bacteria, yeast or fungi, and viruses, which cannot be killed with hot water. This problem can be solved by installing in a specific part of the capsule filter fixture 18, the pressure-resistant and easy to install. Such a filtering device consists of an outer protective casing 19 and at least one of the filtering filler, in particular a filter membrane 20. Preferably, the filter device 18 is rigid, in the sense that it is tougher filtration membranes, and also preferably resistant to significant deflection under the action of fluid and clamping pressure created by emerging from the nozzle the liquid, and tightly appressed to the capsule device�ohms supply of liquid. The advantage of the use of filter devices is that it simplifies the installation of the filter in the capsule, without requiring the use of special connecting means, and reduces the likelihood of damage to the filtration membrane.

To provide antibacterial protection, the pore size of the filter membrane is preferably less than 0.4 μm, most preferably less than 0.2 μm. Its thickness is less than 500 microns, preferably from 10 to 300 μm. The material for the manufacture of the membrane can be selected from the following: polyethersulfone (PSF), cellulose acetate, cellulose nitrate, polyamide and combinations thereof.

In particular, the filter element can be inserted into the seat 21 under the filter formed in the protrusion 11 of the housing. The seat under the filter is designed in such a way that the filtering device has been displaced relative to the compartment. Due to this deformation of the capsule as a result of fluid pressure and pressing device of the fluid can be reduced in comparison with the variant, when the filtering device is located in the center of the compartment. The seat 21 under the filter may be, for example, a U-shaped cavity of relatively small depth (d) versus depth (D) of the compartment. The seat 21 under the filter has a bottom wall and a side wall, with�testwuide at least part of the bottom and side walls of the filtering device, in particular, its larger part 27. To install filtering devices is not required any special connection with the landing place, it can only hold it by pairing with a landing place, for example due to the tight fit to the place, and closing the upper membrane 4. In particular, in the side wall of the mounting seat 21, for example next to the compartment may be made corrugated folds or indentations (not shown) for a tight fit of the filter device.

As shown in Fig.4, the size of the filter fixture 18 is selected in such a way that the filtering surface (F) was at least twice and preferably several times smaller than the larger cross-section (C) of the neck (i.e. the top of the hole) of the compartment 13, for example of the respective upper openings of the compartment. In addition, the largest part of the filtering surface (F) axially offset relative to section (C) of the compartment 13, if you look at the capsule along an axial line A. the term "major portion" is meant at least 60%, preferably 85%, a filtering surface located outside of the cross section of the compartment when viewed in the direction of line A. the Filtering surface of this case is the total surface area of the filter membrane, minus its compressed edge 30. Allowed n�significant overlap surfaces. The first problem is solved reducing the size of the compartment and the ability to better control the deformation of the filter, and the other solved the problem - reducing the number of material used for the manufacture of filter membranes, and, consequently, reduce the cost of production and improving the environmental impact of used capsules. Another advantage is the possibility of crushing the capsule, in particular of the Cup of the capsule, after her discharge, which reduces the amount of storage space used capsules. For this purpose in the side wall of the capsule can be made of weakened line so that they are allowed to compress the Cup in the axial direction.

As shown in Fig.6-9, the filter node according to the invention comprises an inlet wall 22 for supplying the liquid, and the outlet wall 23 for the outlet of filtered liquid in the compartment 13. In an inlet wall has an inlet opening 24 for the fluid and the wall outlet has an outlet 25 for the fluid adjacent to the nozzle 26 of the fixture. The inlet and outlet openings 24, 25 for the liquid separated in the longitudinal direction so that the inlet port 24 to the fluid outside the contour of the compartment 13, and an outlet 25 for the liquid was inside�ri contour of the compartment. Preferably, the filter housing has the shape of a tennis racket, the larger portion 27 of which is in the seat and enters the tapered portion 28 of the nozzle passing over the compartment. The outlet opening 25 preferably has a smaller diameter, for example from 0.2 to 1.5 mm, to create a jet of fluid under pressure, a dissolution or distribution of the ingredients of the liquid exiting the nozzle. The outlet may consist of several individual holes. The number of holes should be small, preferably from 1, to a maximum of 5, in order to avoid significant weakening of the flow velocity. According to one embodiments of the invention in the nozzle there are two parallel or non-parallel outlet. Preferably, the flow rate passing through the exhaust (outlet) channel (channels) of the nozzle is from 1 to 20 m/sec. The cross-section of the outlet channel can have a different shape, for example round, oval, rectangular, etc.

The casing surrounds the filter membrane 20, which is located in the inner chamber 29, formed on the front stream and back stream parts, and the edge 30 of the membrane is firmly and tightly attached to the casing, preventing the flow of fluid to bypass the filter. In the rear the flow of the camera the filter membrane additionally derived� support structure, consisting, e.g., of many small spikes 31. The free ends of the spikes have a flat shape, which reduces the axial deviation of the filter membrane from the action of pressure and to prevent its destruction. Preferably, the spikes are located over the entire area of the filter membrane. Preferably the distance between adjacent spikes not exceed 2.5 mm. Between a support structure formed by a set of channels 32 for collecting the liquid filtered through the membrane. In the outlet wall 23 has at least one discharge channel 33, which provides the message on fluid between the rear downstream part of the filter membrane and an outlet orifice 25 of the nozzle 26 through the channels 32. The supporting structure may be a separate element, such as a lattice, a body placed in the bottom of the filter.

In an inlet wall 22 of the filter fixture also has an inlet opening 34 for the gas intended for supplying compressed gas, for example compressed air, into the compartment 13. As shown in Fig.9, the inlet gas can pass through the wall, crossing the outlet channel 33. In this regard, it should be noted that fed into the gas fixture, following to the nozzle 26, bypasses the filter membrane 20 and is delivered under pressure into the compartment, whereby the filter membrane does not create a pressure drop of gas before starting in from�EC ingredients. Both holes - inlet opening 24 for the liquid and the inlet opening 34 for gas - closed upper membrane 4, so these openings can be selectively opened by perforating the membrane 4 in certain places. In particular, the upper membrane 4 is sealed around the inlet for liquid and an inlet for gas through seals 35, 36 (Fig.1). Thus, when the top membrane is punctured with a nozzle 7 for supplying gas feeder fluid, perforating tip may come into contact only with the filtered liquid. Due to this, the possibility of contamination of the punching device is significantly reduced compared to the situation as if for the gas and liquid would be used the same inlet. Thus, perforating means for gas to remain pure preparatory for the next cycle.

The design of the casing 19 of the filter may be different. However, according to a preferred construction, the casing consists of two parts 37 and 38, which are bonded and/or snapped with each other. Fig.7 shows the filter device 18 with the lower and upper halves 37 and 38 of the casing. In the lower half 37 of the casing has a protruding circular rim/groove 39, the bounding contour of the internal chamber and inserted into the circular groove/ferrule 40 in�rhna half 38 of the housing. Similarly, a nozzle part 28 of the fixture 18 is formed by the connection of the second rim and recesses 41 of the bottom halves with a groove/rim 42 of the upper half 38. It is also allowable that the parts 39, 41 and 40, 42 is continuously passed from the larger part 27 "racket" to the tapered portion 28 "racket".

As shown in Fig.10 and 11, the lower and upper halves 37, 38 of the casing are connected, compressing the edge of the filtration membrane 30. The parts 37, 38 can be designed in such a way that they are bent and clamped the edge of the membrane around the circumference of 43. The filter may not be welded to the casing, if the clip allows you to securely hold the filter in place and, therefore, guaranteed to eliminate filter bypass fluid during operation. For example, the device may be assembled by welding sections of the grooves/rims on the lines 44, 45. Welding parts of the casing by crimping of the filter allows for a wider range of materials for the filter without worrying about compatibility with the materials used for the casing. Another advantage of this design is the simplification of the Assembly, since ultrasonic welding allows the use of thicker structural elements and to prevent damage to more delicate items (e.g., filtration membranes).

As shown in Fig.8, design f�Trouser fixtures can be optimized. For example, the filter device may include a reinforcing structure 46 that is located, in particular, the tapered portion 28 that allows the channel in the bottom wall, without compromising the rigidity of the element, in particular, from the viewpoint of liquid and mechanical constraints. In particular, the reinforcing structure consists of several edges passing, for example, transversely "racket". Of course, you can use other reinforcing structure. In particular, to reduce costs and improve environmental performance you can optimize the ratio stiffness/weight.

To reduce the likelihood of damage to the filter membrane when opening the inlet 24 to the fluid during the perforation of the membrane 4 in the area 47, located directly above the inlet, as shown in Fig.12, between the inlet and the filter membrane 20 is set resistant to perforation of the septum 48 which may be an integral part of the inlet wall of the housing. The baffle is located under the inlet transversely to him. In this way, the fluid can pass through the lateral passages 49 formed in the inlet between the baffle and the wall. Of course, the shape of the septum may be different, provided that it provides protection from perforating the OS�PTO direction I inlet. The partition can also be a separate part that is located between the filter and the inlet wall.

Another embodiment of the invention shown in Fig.13 and 14.

Capsule 1B in accordance with this embodiment of the invention has several differences. First of all, the filter device 18 consists of an outer wall 23 that supports the filter membrane 20. Unlike the previous version of the filter membrane 20 is located between the outer exhaust wall 23 and the bottom of the seat 21 under the filter housing. The inlet opening 24 for the fluid is on the side of the fixture and communicates with the bottom chamber 50 located on the stream before the filter, but below the outlet wall 23. The second upper chamber 51 is located between the outlet wall 23 and the upper membrane 4 (not shown) which is hermetically attached to lanzoprazole the rim 5 of the body of the capsule. To the upper membrane 4 has not failed in the upper chamber 51 and partially block the airflow passing through the filter membrane to the outlet wall 23 has several support elements 52. In the outlet wall 23 provided with a plurality of holes 53, allowing the filtered liquid to evenly pass through the button located at the bottom of the filter membrane. Thus, the liquid supplied to the capsule via the inlet hole�rsta 24, following in the lower chamber 50, passes from the bottom of the fixture, and then through the filter membrane 20 rises. Thus, the filtered liquid is accumulated in the upper chamber and passes through the outlet nozzle 26 having a small hole 25. For unloading of the capsule 1B can be used, the inlet port for gas that is located separately from the filtering device. In particular, in lanzoprazol the rim, for example next to the filter device can be made recess 54. For feeding gas into the compartment 13 with the ingredients of the upper membrane may perforirovanie in the area of the pit. Perforation of the upper membrane may be a mechanical element of the device for supplying liquid or compressed gas. Of course, the inlet gas may also be located and in a filtering device. The system of release of the product may be similar to those described above.

Next, with reference to Fig.15-20 will be described the dispensing of a fluid medium, which can store a capsule for preparing a food mixture.

In the device 55 of the flow of a fluid medium according to the invention usually has a holder for 56 capsules, the size of which allows you to set it to 1 capsule. The capsule holder is attached to a pulley 57 of the flow of a fluid medium, comprising means for conveying fluid of ijaza. Block 57 of the feed fluid comprises a base 58 of the capsule holder providing a stable starting position of the capsule holder. In particular, the holder 56 of the capsule and the base 58 has a mating guide rails 59 for easy installation and removal of the holder capsules with bases, for example, by sliding in the longitudinal direction of V.

It should be noted that the filtering device 18 according to the invention may also be a separate part, attached to the capsule when using, for example, placing the capsule in the feeder fluid. In particular, the filter device may be a part, which is connected to the nozzle for fluid, or is part of an atomizer for liquids.

Block 57 of the flow of the fluid also contains a plate 60 of the injection fluid, the nozzle carrier 6 for the liquid. Plate 60 of the injection fluid may be installed rotatably around the axis 61 that is installed on top of the base 58 so that the plate can be moved from at least one first position in which the nozzle is removed from the inlet for fluid on the capsule, a second position in which the nozzle includes an inlet opening 24 for the liquid on the capsule. The first position shown in Fig.17, and a second position - in Fig.18.
