The present invention relates to a cartridge for the preparation of beverages and, in particular, to a sealed cartridges, which are made from essentially airtight and waterproof materials and which contain one or more ingredients to prepare drinks.

Previously it was proposed to seal the ingredients to prepare drinks in separate airtight containers. For example, the known cartridges or capsules containing compacted ground coffee intended for use in some machines for making coffee, which is usually called the machines "espresso". When preparing coffee using these machines cartridge with coffee placed in the cooking chamber, and passed through the cartridge under a relatively high pressure hot water, thus removing from ground coffee aroma components with getting a coffee drink. Typically, these machines work under pressure more than 6X105PA. Espresso machines of the type described to date have been quite expensive, because the machine components such as water pumps and seals must withstand high pressure.

In the application WO 01/58786 described cartridge for the preparation of drinks, which operates under pressure in the General range of 0.7 to 2,h5PA. However, this cartridge is designed is for use in a machine for preparing a drink for commercial or industrial market and is relatively expensive. Therefore, a need remains in the cartridge for the preparation of beverages, in which the cartridge and the machine for preparing a beverage suitable, in particular on the cost, performance and reliability, for use in everyday life.

Was also difficult to sterilize cartridges for drinks types described above, which is associated with narrow and winding channels which are formed in the cartridge cases. Sterilization, for example by exposure to water vapor cartridges may not be completely effective for meandering channels, which is associated with the characteristics of the surface tension of the ink cartridge, which prevents the penetration of water vapor in meandering channels and therefore does not allow the impact of water vapor on the surface of the component.

Cartridges for drinks can deal with the problems of splashing and splashing, which in the issuance of a beverage from a cartridge for drinks is spraying and splashing outside of the receiver. This is especially true in the case of the issuance of drinks under a relatively high pressure. Attempts to mitigate this problem by applying on the machine for preparing a drink wydanego probe to guide a drink at the receiver. However vydatnou probe tends to contamination over time, the remnants of the drink and with whom Ruud cleanable. In addition, there is the possibility of cross contamination of beverages of different types.

In addition, in the cartridge according to the application WO 01/58786 form a strong jet of beverage by passing the beverage through the opening. Was difficult to accurately determine the size and location of holes of this type. Clearly establish the size and positioning of the holes is very important because it is crucial for proper trapping of air bubbles in the finished drink. The formation of the small holes is particularly difficult in parts, the obtained injection molding, in which the placement of the holes is internal, and it is surrounded by other parts details. The traditional way of forming holes is to use a molding studs, the dimensions of which correspond to the required hole diameter. However, the holes formed by molding pins can usually be directed only to the doorway into the details (which opening provides access moulding studs in detail during molding). In the cartridge for a drink this leads to a very rapid issuance of drink from the opening speeds of up to 12-16 m/s, because it goes directly to the outlet.

One of the reliability factors of the cartridges is their ability to withstand the increased internal pressure.

For th is would reduce the cost of these cartridges, it is desirable to make them simple, reliable way. In particular, it is desirable to reduce the share of transactions with parts manual as well as to reduce the total number of parts.

Accordingly, the present invention provides a cartridge containing one or more beverage ingredients and are made of an essentially air - and water-impermeable materials, the cartridge includes an inlet for introduction into the cartridge of the water environment and an output for issuing a drink obtained from one or more beverage ingredients, additionally, the cartridge includes an outer element and the inner element are integrated into one unit with an external element, characterized in that the inner element contains vydatnou pipe forming the outlet of the cartridge.

The cartridge according to the invention is easily assembled from basic components, which are the inner element and outer element. The use of separate components for internal and external elements, which are then combined into a single node, allows to optimize the production of each component. This is especially useful in the cartridge according to the invention, in which the desired very small tolerances, because the path of flow of the beverage through the cartridge is limited by the boundary surface between the outer element and inner element. In addition, components of the internal element, the outer element can more easily be sterilized prior to Assembly, when they separated. Immediately after connecting components, the result is somewhat narrow, winding paths, which cannot be sterilized by known methods. The sterilization of components is a particularly important advantage in the case when cartridges are used in the manufacture of beverages based on milk products. In addition, through the use of separate components that are combined, the cartridge is not required to turn in the Assembly process, because the connection of the inner element and, optionally, filter, filling the cartridge ingredients of the drink and the connection of the cover, such as laminated material, can all be done with the same orientation of the outer element.

Preferably, the inner element contains vydatnou pipe. Vydatnou pipe is used to guide issued by the drink in the receiver, such as a Cup. Vydatnou socket allows you to avoid splashing or spraying of the drink and is also useful in regulating the flow characteristic of the beverage during its transfer from the cartridge into the receiver. For example, widocznoa nozzle can be attached to the form, allowing to reduce the degree of turbulence, given to drink, to avoid unwanted decrease the number of bubbles contained in the drink. The advantage of finding the tsya also the cartridge itself contains vydatnou pipe rather than having a separate wydanego pipe or probe in the car to make the drink. This eliminates the danger of cross-contamination kinds of beverage between cycles of preparation and delivery, as each vydatnou pipe is used only once and then discarded along with the rest of the cartridge. In addition, preferably, drink, issued through vydatnou pipe, will not communicate with the exhaust mechanism of the machine for preparing a drink, thus avoiding contamination of the machine making the drink the remnants of the drink. Preferably, vydatnou nozzle forms one whole with the inner element. Preferably, vydatnou pipe and the inner element is formed under pressure or otherwise in the form of a single node, which reduces the cost of manufacture of the cartridge and reduces the number of components requiring Assembly.

In another additional embodiment, vydatnou pipe contains a partition, continuing for at least part of the length wydanego pipe. The baffle reduces the amount of splashing and splashing netcapi issue.

Preferably, for the mutual connection of the outer element and inner element applies landing with a snap. Usually landing with snap contains siteplease patterns on the inner element and the outer element. Landing with snap offers fast during Assembly, but a reliable method of connection of the inner element and outer element. The advantage is that landing with a snap eliminates the need for glue or other adhesives inside the cartridge, in which they will be open to contact with the ingredients of the drink.

Preferably, the outer element includes a closed first end and an open second end, with the inner element, which is connected with the outer element, the output wydanego pipe is turned to the open second end. Also preferably, the entrance facing to the open second end of the external element. Thus, the input and output directed to the same side of the cartridge. This allows you to use the cartridge in a low-profile machine, and punching means for forming input and output when using protrude from one plane of the machine for making beverages.

Preferably, the outer element and the inner element are connected at the closed first end of the external element or next to it. That is they way the connection of the inner and outer elements is achieved at a point remote from the open end or mouth of the outer element. Preferably, the join operation can be performed before filling cartridge ingredients of the drink and to seal the open end or mouth of the cartridge. This simplifies the Assembly process, since the inner and outer elements may be first connected to education Assembly cartridge, which can then be moved to the site filling packaging line in which it is placed one or more beverage ingredients. Then the filled cartridge seal, for example, laminated sheet, which are welded by heat to the open end of the outer element. This Assembly process avoids the difficult task of aligning and maintaining alignment of the outer element, the inner element and the laminated material during the operation of the welding heat.

Preferably, the outer element contains turned inward protrusion, which is inserted into the middle end wydanego pipe when connecting the external element and the internal element.

In one embodiment, the inner element contains a frame in which is placed a filter.

The cartridge according to the invention creates a strong p is Yu drink, which can be used to change the appearance and specifications issued by the drink, for example, by trapping air jet of the beverage to create many small drinks issued in the drink. The cartridge according to the invention is easily assembled from basic components, which are the inner element and outer element. The use of separate components for internal and external elements, which are then combined into a single node, allows to optimize the production of each component. This is especially useful in the cartridge according to the invention, which requires a very small tolerances to determine the size and location of the holes, creating a strong jet of beverage, but also for the rest of the path of flow of the beverage through the cartridge. In addition, the hole may be directed perpendicular to the General direction of the flow path, so that the drink hits the wall or the surface of the cartridge and thus slows down before it is issued. As described above, such accuracy and orientation of the holes is difficult components obtained by way of injection molding. According to the invention, this difficulty is overcome by limiting apertures through the use of transition between the inner element and outer element instead of forming the entire hole into separate components is NTE using, for example, the molding pins.

Preferably, one of the inner element and outer element includes an aperture and the other from among the inner element and outer element contains an obstacle, so that the location of the inner element to the outer element obstacle partially covers the opening, thus forming a hole.

Preferably, the easier it is to make a separate aperture and the obstacle, which can be combined to limit the holes. Preferably, the opening comprises an elongated slit that can be performed in the inner element. In this case, the outer element contains an obstacle.

Preferably, the barrier contains the ledge of the outer element, at least part of which is projected on the inner element. Elongated slit may be made in the cylindrical wall of the inner element. Preferably, the elongated slit reaches the upper edge of the cylindrical wall. In one embodiment, the protrusion of the outer element is a cylindrical projection, which is a sliding fit in the cylindrical wall of the inner element. Typically, the hole has a cross sectional area of 0.4 to 0.7 mm2.

Preferably, the cartridge also includes at least one inlet for air and a means of lowering the pressure forces the Noah jets drink so in the process of using at least one suction air flows into the beverage in the form of many small bubbles. Preferably, at least one inlet for air is made in the inner element after the opening. The internal element may contain vydatnou pipe forming the outlet. Preferably, a strong jet of the beverage coming out of the hole, goes to vydatnou pipe, where it can impinge upon the surface wydanego pipe between the expiration of the holes and the expiry of the exit. Preferably, the surface is concave wall wydanego pipe. Concave wall preferably is located on the opposite against the opening side wydanego pipe. Preferably, the hole directs the flow of the beverage is essentially perpendicular to the flow of the beverage flowing from the output. The beverage thus is rejected before it can leave the cartridge, this leads to a slow drink that is required in order to prevent splashing in the sink.

The components of the inner element and outer element can more easily be sterilized before Assembly, when they are separated. Immediately after connecting components, the result is somewhat narrow, winding paths, which cannot be sterilized by known methods. The possibility of stabilisationoriented is a particularly important advantage in the case, when cartridges are used in the issuance of drinks based on milk products.

Preferably, vydatnou nozzle forms one whole with the inner element. Vydatnou pipe is used to guide issued by the drink in the receiver, such as a Cup. Vydatnou socket allows you to avoid splashing or spraying of the drink and is also useful in regulating the flow characteristic of the beverage during its transfer from the cartridge into the receiver. For example, widocznoa nozzle can be attached to the form, allowing to reduce the degree of turbulence, given to drink, to avoid unwanted decrease the number of bubbles contained in the drink. The advantage is that the cartridge itself contains vydatnou pipe rather than having a separate wydanego pipe in the car to make the drink. This eliminates the danger of cross-contamination kinds of beverage between cycles of preparation and delivery, as each vydatnou pipe is used only once and then discarded along with the rest of the cartridge. In addition, preferably, drink, issued through vydatnou pipe, will not communicate with the exhaust mechanism of the machine for preparing a drink, thus avoiding contamination of the machine making the drink the remnants of the drink. PR is doctitle, vydatnou pipe and the inner element is formed under pressure or otherwise in the form of a single node, which reduces the cost of manufacture of the cartridge and reduces the number of components requiring Assembly.

Preferably, the cartridge is disc-shaped. The outer element and/or the inner element is performed, for example, from polypropylene. The cartridge may be made of biodegradable polymer.

The present invention also provides a cartridge containing one or more beverage ingredients and are made of an essentially air - and water-impermeable materials, the cartridge contains a compartment containing one or more beverage ingredients, the compartment containing a multiplicity of holes intended for the introduction of the water environment in this Department, and the number of output holes for a drink obtained from one or more beverage ingredients, in which at least part of the inlet holes is not combined with the output apertures so that at least part of the aqueous medium entering the compartment through the inlet is subjected to circulation in the Department before you leave the compartment through the outlet, wherein the inlet is located at the periphery of the compartment.

Preferably, the cartridge from which briteney contains the inlet and outlet openings, at least part of which is not combined. This prevents water entering the compartment containing the beverage ingredients to pass directly from the inlet to the exhaust outlets. Instead, the aquatic environment is forced to circulate in the Department before exiting through the outlet. This increases the degree of mixing of the water environment and ingredients of the drink, because, essentially, all of the ingredients of the drink in the Department caught in the path of flow of the water environment.

Preferably, the inlet can be placed at equal intervals along the periphery of the compartment. Preferably, the outlet openings are located closer to the center compartment compared with the input holes. Outlets can be placed at equal intervals around the center of the branch. The inlet and outlet openings intervals provides more uniform characteristics of the flow within the compartment that provides a more uniform mixing of the ingredients of the drink and the water environment.

Preferably, the cartridge contains from 3 to 10 openings. In one embodiment, the provided 4 of the inlet.

Preferably, the cartridge contains from 3 to 10 outlets. In one embodiment, the provided 5 output hole at back the s.

Preferably, applies unequal number of input apertures and output apertures.

Preferably, the number of input apertures and output apertures is determined by the formula

Xo=Xi+C

where Xi- the number of entrance holes,

Xabout- the number of output holes,

C - the set of integers excluding 0 or nXi,

n is any integer.

Preferably, the number of input apertures and output apertures is chosen according to the specified formula. This is particularly useful when the disc-shaped cartridge, and the holes are spaced intervals around the cartridge, since there is no need to deliberately align during Assembly the components of the cartridge containing the input apertures and output apertures. At any relative orientation of the components at least part of the input apertures and the output apertures to be aligned. For example, if four inlets and five output holes, all of which are intervals, it is not possible to combine more than one inlet one outlet for any alignment of components containing the input and output apertures. It leads to much more rapid and simple Assembly process. On the other hand, the cartridge may contain identical to the number of input apertures and output apertures, but the intervals between them can be chosen in such a way as to ensure that at least part of the inputs and outputs are not combined.

Typically, the inlet holes are located in the outer element of the cartridge and the outlet openings are located in the inner element of the cartridge. Preferably, the inner element contains vydatnou pipe which is connected with the output holes.

In a preferred embodiment, the cartridge is disc-shaped. Preferably, the flow of the water passing through the inlet to the Department, is directed radially inwards towards the centre of the cartridge.

In one of the applications in the cartridge 1 contains the ingredient in the form of liquid chocolate with a viscosity of from 1700 to 3900 MPa at ambient temperature and from 5,000 to 10,000 MPa at a temperature of 0°C and refractive solids 67 Brix ±3. In other applications in the cartridge 1 contains liquid coffee with a viscosity of from 70 to 2000 MPa at ambient temperature and from 80 to 5000 MPa at a temperature of 0°C, but the coffee has a total content of dry matter at the level of from 40 to 70%.

When the soluble ingredients of the drink, such as a viscous liquid or gel, incomplete mixing is of ngredients with the aquatic environment can pose a serious problem. In particular, the cartridges containing such products, may rapid emergence of channels connecting the inlet and outlet of the cartridge, due to local dissolution of the ingredient. The channels form then the path for the flow of the remaining water environment with relatively low resistance, and water will tend to flow through these channels and not through the remaining, not dissolved, viscous ingredient in the Department. The cartridge according to the invention largely solves this problem by forcing the water environment to circulate within the unit, which leads not only to the dissolution of the larger proportion of the ingredients, but also creates turbulence within the unit, which improves the mixing of the remaining ingredient, which, in turn, prevents the formation or preservation of paths for the flow with low resistance connecting the inlet to the outlets.

The outer element and/or the inner element may be made from polypropylene and can be obtained by injection molding. In one embodiment, the outer element and/or the inner element is made of biodegradable polymer.

Vydatnou socket allows you to avoid splashing or razbryzgivanie the drink and is also useful in regulating the flow characteristic of the beverage during its transfer from the cartridge into the receiver. For example, widocznoa nozzle can be attached to the form, allowing to reduce the degree of turbulence, given to drink, to avoid unwanted decrease the number of bubbles contained in the drink. The advantage is that the cartridge itself contains vydatnou pipe rather than having a separate wydanego pipe or probe in the car to make the drink. This eliminates the danger of cross-contamination kinds of beverage between cycles of preparation and delivery, as each vydatnou pipe is used only once and then discarded along with the rest of the cartridge. In addition, preferably, drink, issued through vydatnou pipe, will not communicate with the exhaust mechanism of the machine for preparing a drink, thus avoiding contamination of the machine making the drink the remnants of the drink. Preferably, vydatnou nozzle forms one whole with the inner element. Preferably, vydatnou pipe and the inner element is formed under pressure or otherwise in the form of a single node, which reduces the cost of manufacture of the cartridge and reduces the number of components requiring Assembly.

In one embodiment, vydatnou nozzle includes a tapered section. In an alternative embodiment, vydatnou pipe will win the cylindrical section. In another additional embodiment, vydatnou pipe contains a partition, continuing for at least part of the length wydanego pipe.

The inlet 121 and outlet 122 are initially sealed laminated material 5 and is opened when using by punching or cutting the laminated material 5. The path for the flow of beverage is determined by the spatial relationship between the outer element 2, inner member 3 and the laminated material 5, as will consider the network below. In the cartridge 1 may be further include another component, such as the filter 4, as will be described later.

The first version of the cartridge 1, which will be described in order to prepare, shown in figure 1-11. The first version of the cartridge 1 is particularly suited for use in the issuance of filtered products such as roast and ground coffee or leaf tea. However, this variant of the cartridge 1 and the other options described below may be used with other products, such as chocolate, coffee, tea, sweeteners, stimulating drinks, condiments, alcoholic drinks, flavoured milk, fruit juices, squash, sauces and desserts.

As shown in figure 5, the cartridge 1 has a General circular or disc shape, and the diameter of the cartridge 1 in General much larger than its height. The main axis X passes through the center of the outer element, as shown in figure 1. Usually the whole diameter of the outer element 2 is 74,5 mm ±6 mm and the total height is 16 mm ±3 mm is Usually the volume of the cartridge 1 after the Assembly is equal to 30.2 ml ±20%.

The outer element 2 in General contains a Cup-shaped casing 10 having a curved annular wall 13, a closed top 11 and an open bottom portion 12. The diameter of the outer element 2, the top 11 is smaller than the diameter of the lower part 12, which is associated with the expansion of the annular wall 13 of the bottom, in the transition from closed is in the top 11 to the open bottom 12. The annular wall 13 and a closed bottom 11 is formed along the receiver with the interior 34.

As shown more clearly in figure 2, the cylindrical projection 18 includes a stepped profile having first, second and third sections 19, 20 and 21. The first section 19 has the shape of a regular cylinder. The second section 20 has the shape of a truncated cone and beveled. The third section 21 is another correct cylinder and closes the bottom surface 31. The diameter of the first, second and third sections 19, 20 and 21 is gradually reduced, so that the diameter of the cylindrical protrusion 18 is reduced when moving from the top 11 to the closed bottom surface 31 of the cylindrical protrusion 18. In General, horizontal shoulder 32 is formed on a cylindrical flange 18 at the interface between the second and third sections 20 and 21.

On the outer element 2 in the direction of the lower part 12 is protruding outward shoulder 33. Protruding outward shoulder 33 forms a secondary wall 15, coaxial with the annular wall 13 so as to limit the circular path, forming the pipe 16 between the secondary wall 15 and the annular wall 13. The pipe 16 passes through the circumference of the outer element 2. In the annular wall 13 is the number of slits 17 flush with trubor what Bodom 16, in order to provide the movement of gas and liquid between the pipe 16 and the inner part 34 of the outer element 2. As shown in figure 3, the slits 17 are vertical slits in the annular wall 13. Apply 20 to 40 slots. In the shown embodiment, is used thirty-seven slots 17, are placed in a common intervals around the circumference of the pipe 16. Slit 17 preferably have a length of from 1.4 to 1.8 mm is Usually the length of each slit is 1.6 mm, accounting for 10% of the total height of the outer element 2. The width of each slit is from 0.25 to 0.35 mm is Usually the width of each gap is 0.3 mm Seli 17 sufficiently narrow in order to avoid contact of the beverage ingredients in the pipe 16 as during storage and use.

The inlet chamber 26 is formed in the outer element 2 on the periphery of the outer element 2. As best shown in figure 5, is provided by cylindrical wall 27, which forms itself in the inlet 26 and separates the inlet chamber 26 from the inner part 34 of the outer element 2. Cylindrical wall 27 has a closed top surface 28, which is located in the plane perpendicular to the main axis X, and an open lower end 29 located in the same plane with the bottom part 12 of the outer element 2. The inlet chamber 26 is communicated, as shown in figure 1, with the pipelines is om 16 through two slits 30. On the other hand, for communication between the pipe 16 and the input chamber 26 can be used from one to four slits.

The lower end protruding outward of the shoulder 33 provided with protruding outward flange 34, which runs perpendicular to the main axis X. Typically, the flange 35 has a width of from 2 to 4 mm Portion of the flange 35 is enlarged, forming a handle 24 which may be used to hold the outer element 2. The handle 24 is provided with a turned up edge 25 to improve grip.

The outer element 2 made in one piece from high-density polyethylene, polypropylene, polystyrene, polyester or laminated material of two or more of the above materials. Suitable polypropylene can choose from a number of polymers, supplied by DSM UK Limited (Reddish, UK). The outer element may be opaque, transparent or translucent. The production process can be injection molding.

The internal element 3, as shown in Fig.7-10, contains an annular frame 41 and the exhaust down the cylindrical funnel 40. The main axis X, as shown in Fig.7, passes through the centre of the inner element 3.

As shown best in Fig, the annular frame 41 includes an annular rim 51 and the inner sleeve 52, which are connected to ten posted by intervals of radial ridges 53. Inside the I sleeve forms one whole with the cylindrical funnel 40 and away from it. In the annular frame 41 between the radial ridges 53 are made of the filter hole 55. The filter 4 is placed on the annular frame 41 so as to cover the filter hole 55. The filter is preferably made of a material having a high strength in the wet state, for example, non-woven fibrous material of polyester. Other materials that can be used include waterproof pulp material, such as cellulosic material containing-woven paper fibers. Woven paper fibers can be mixed with polypropylene fibers, polyvinyl chloride and/or polyethylene. The inclusion of these plastic materials in the pulp material makes cellulosic material termoskleivaniya. The filter 4 can also be treated and covered with material that is activated by heat and/or pressure, so that it can stick to the annular frame 41 so.

As shown made in the context of the profile 7, when the inner sleeve 52 is located in the lower position relative to the outer rim 51, the annular frame 41 has an inclined lower profile.

The upper surface of each jumper 53 provided with a rising wall 54, which separates the cavity space above the annular frame 41 on many passages 57. Each passage 57 limited when the parties partition 54 and the bottom of the filter 4. The passages 57 are from the outer rim 51 down to the cylindrical funnel 40, opening into the openings 56, bounded by the inner edges of the partitions 54.

Cylindrical funnel contains the inner tube 42 surrounding the inner vydatnou pipe 43. Outer tube 42 forms the outer part of the cylindrical funnel 40. Vydatnou pipe 43 is connected with the outer pipe 42 at the upper end wydanego pipe 43 through the annular flange 47. Vydatnou pipe 43 includes at the upper end of the inlet 45 which communicates with the openings 56 of the passages 57 and exit 44 at the lower end, through which the prepared drink throw in a Cup or other receiver. Vydatnou pipe 43 contains a plot in the form of a truncated cone 48 at the upper end and the cylindrical section 58 at the lower end. The cylindrical section 58 may have a slight taper so that it tapers towards the outlet 44. Section 48 in the form of a truncated cone helps to convey the beverage passes from 57 down in the direction of exit 44, without imparting turbulence to drink. The upper surface 48 in the form of a truncated cone provided with four supporting crosspieces 49, placed at equal intervals around the circumference of the cylindrical funnel 40. Reference jumper 49 form the channels 50 between them. The upper edge of the load-bearing lintels 49 are located on the same level as the other the other and perpendicular to the main axis X.

The internal element 3 can be made in one piece from polypropylene or similar material, as described above, and by injection molding in the same manner as the outer element 2.

On the other hand, the internal element 3 and/or the outer element 2 can be made of biodegradable polyethylene (for example, SPITEK, which supplies the company Symphony Environmental, Borehamwood, UK), biodegradable polyetherimide (for example, BAK 1095, which supplies the company Symphony Environmental), dairy PolicyKit (PLA, which supplies the company Cargil, PCs Minnesota, USA), polymers based on starch, cellulose derivatives and polypeptides.

Laminated material 5 is formed from two layers, the first layer of aluminum and a second layer of cast polypropylene. The thickness of the aluminum layer is from 0.02 to 0.07 mm Thickness molded polypropylene ranges from 0.025 to 0,065 mm In one embodiment, the thickness of the aluminum layer is 0.06 mm and a layer of polypropylene - 0,025 mm This laminated material is particularly suitable because it has a greater resistance to twisting during Assembly. In the laminated material 5 can be pre-cut into the desired size and shape and then transfer Assembly on the production line when it is not under argueta warping. Therefore, the laminated material 5 is particularly suitable for welding. You can use other layered materials, including laminated material PET/Al/PP, PE/EVON/PP, PET/metalized/PP and Aluminum/PP. Instead carved stamp blanks you can use the laminated material in rolls.

Instead of flexible laminated material cartridge 1 can be closed by a rigid or semi-rigid cover.

The cartridge Assembly 1 includes the following operations:

a) the internal element 3 is inserted into the outer element 2;

b) filter 4 cut into desired shape and place on the inner element 3 thus, in order to place it on top of the cylindrical funnel 40 and to impose on the annular frame 41;

(C) the internal element 3, the outer element 2 and the filter 4 are combined by ultrasonic welding;

d) the cartridge 1 is filled by one or more beverage ingredients;

e) laminated material 5 is attached to the outer element 2.

These operations will be described in more detail below.

The outer element 2 are equipped with an open bottom part 12 facing upward. The internal element 3 is then put into the outer element 2 with an outer rim 51, freely planted in the axial protrusion 14 on the top 11 of the cartridge 1. A cylindrical protrusion 18 of the outer element 2 at the same time inserted at the top the art of the cylindrical funnel 40 of the inner element 3. The third section 21 of the cylindrical protrusion 18 is placed within the cylindrical funnel 40 with a closed bottom surface 31 of the cylindrical protrusion 18, based on the reference jumper 49 inner element 3. Then on the inner element 3 put the filter 4 so that the filter material is in contact with the annular rim 51. After this, the process of welding by ultrasound are used for connection of the filter 4 with the internal element 3 and at the same time, and during the same operation process for coupling the inner element 3 with the outer element 2. The internal element 3 and the filter 4 weld on the outer rim 51. The internal element 3 and the outer element 2 connected by means of welded seams around the outer rim 51 and, in addition, the upper edges of the bridges 54.

As most clearly shown at 11, the outer element 2 and the inner element 3, being joined together, form a cavity 130 in the inner part 120 below the annular flange 41 and the outer part of the cylindrical funnel 40, forming a filter chamber. The filter chamber 130 and the passages 57 above annular frame 41 are separated by the filter paper 4.

The filter chamber 130 contains one or more beverage ingredients 200. One or more beverage ingredients Packed in the filter chamber 130. Drink filtered type ingredient usually I have is roasted ground coffee or leaf tea. The packing density of the beverage ingredients in the filter chamber 130 may vary as desired. Usually, to obtain filtered ready coffee filter chamber contains from 5.0 to 10.2 grams of roasted and ground coffee in the filter layer of normal thickness 5-14 mm Optional internal part 120 may contain one or more bodies, such as balls, which move freely in the inner part 120, promoting mixing by inducing turbulence and destroying fat ingredients of the beverage at the time of issue of the drink.

Laminated material 5 then attach to the outer element 2 through the formation of a weld 126 on the periphery of the laminated material 5 for the connection of the laminated material 5 with the lower surface protruding outward flange 35. Weld 125 continues for a tight attachment of the laminated material 5 to the bottom edge of cylindrical wall 27 of the input chamber 26. Further, between the laminated material 5 and the lower edge of the outer tube 42 of the cylindrical funnel 40 form a welded seam 125, so that the inner element 3 continues between the outer element 2 and the laminated material 5. Laminated material 5 forms the lower wall of the filter chamber 130 and seals the entrance to the chamber 26 and the cylindrical funnel 40. However, re the issue between the laminated material 5 and the lower edge of wydanego pipe 43 there is a small gap 123. Application of various welding methods, such as welding heat and ultrasound, depending on the characteristics of the laminated material.

Preferably, the inner element 3 continues between the outer element 2 and the laminated material 5. The internal element 3 is made of material having relative rigidity, such as polypropylene. As such, the internal element 3 forms the element carrying the load, which serves to hold the laminated material 5 and the outer element 2 are separated by compression of the cartridge 1. Preferably, when using the cartridge 1 was subjected to a compressive load from 130 to 280 N, the load is attached machine for preparing a beverage, in which the inserted cartridge. However, the specific arrangement of the cartridge and the machine may use less effort, greater than 50 N. The compressive force helps to prevent the destruction of the cartridge under the influence of internal pressure and also serves to press together the inner element 3 and the outer element 2. This ensures that the internal dimensions of the passages and holes in the cartridge 1 are fixed and cannot be changed during the discharge pressure in the cartridge 1.

To use the cartridge 1 is first inserted into the machine for preparing beverages, QCD is they the inlet 121 and outlet 122-piercing elements of the machine for preparing beverages who punched and bent laminated material 5. Aqueous medium, typically water, enters the cartridge 1 under pressure through the inlet 121 in the entrance chamber 26 under the pressure of 0.1-2.0 bar. From here the water is directed to flow through the slit 30 and around the pipe 16 in the filter chamber 130 of the cartridge 1 through the number of gaps 17. Water is directed radially inward through the filter chamber 130 and mixed with ingredients 200 beverage contained therein. At the same time, water goes up through the ingredients of the drink. Drink, formed when water passes through the ingredients of the beverage passes through the filter 4 and the filter hole 55 in the passages 57, lying above the annular frame 41. Tight connection of the filter 4 with the ridges 53 and the welding of the rim 51 to the outer element 2 warrants workarounds and that the drink must pass through the filter 4.

Then the drink flows down along the radial passages 57 formed between the ridges 53 and through the openings 56 in the cylindrical funnel 40. Drink passes along the channels 50 between the support ridges 47 and down widocznoa the chute 43 to the output 44 from which the drink is produced in the receiver Cup type.

Preferably, a machine for making a beverage contains the blower air, which blows compressed air through the cartridge 1 at the end of the RA is Otsego cycle, to drain the remaining beverage in the receiver.

On Fig-18 shows the second variant of the cartridge 1. The second variant of the cartridge 1 is designed for use when issuing products such as espresso, such as roasted and ground coffee, when it is desirable to get a drink containing foam or tiny bubbles known as "cream" (Italian : "foam"). Many of the signs of the second variant 1 are the same as in the first embodiment, and to indicate the same characteristics are used in the same numerical position. In the further description will discuss the differences between the first and second options. Common signs of acting in the same way, be considered in detail will not.

The outer element 2 has the same design as in the first embodiment of the cartridge 1, and as shown in Fig.1-6.

The annular frame 41 of the internal element 3 is the same as in the first embodiment. In addition, the filter 4 is located on the annular frame 41 so as to cover the filter hole 55. Outer tube 42 of the cylindrical funnel 40 is also the same as before. However, there are some differences in the design of the inner element 2 of the second variant in comparison with the first option. As shown in Fig, vydatnou pipe 43 provided with a partition wall 65, which is partly up widocznoa the pipe 43 from the outlet 44. Pereg Radka 65 helps to prevent splashing and/or splashing of the beverage as it comes out of wydanego pipe 43. Profile wydanego pipe 43 is also different and contains a stepped profile with clearly visible curvature 66 near the upper end of the pipe 43.

Provides a rim 67, rising from the annular flange 47 and connecting the outer tube 42 with videcnik pipe 43. Rim 47 surrounds the inlet 45 in vydatnou pipe 43 and forms an annular channel 69 between the rim 67 and the upper part of the outer pipe 42. Rim 67 is supplied with the inward facing shoulder 68. At one point on the circumference of the rim 67 is made a hole 70 in the form of a slit running from the top edge of the rim 67 to a point located at a minimum distance below the level of the shoulder 68, as best shown in Fig and 13. The slot width is 0.64 mm

In the annular flange 47 provided input 71 for air, combined on a circle with a hole 70, as shown in Fig and 17. Input 71 for air contains a hole passing through the flange 47 so as to provide communication between a point above the flange 47 and the cavity below the flange 47 between the outer pipe and videcnik pipe 43. Preferably, and as shown, the inlet 71 for air contains upper portion 73 in the shape of a truncated cone and the lower cylindrical section 72. Entrance for air 71 is typically formed by molding tool, such as a hairpin. The tapered profile of the input 71 for air facilitates removing the forming tool from formof the frame component. The wall of the outer tube 42 near the entrance 71 for air given the shape of the trench 75 leading from the entrance for air 71 to the input 45 wydanego pipe 43. As shown in Fig, between the input 71 for air and chute 75 is formed a beveled shoulder 74 to ensure that a strong jet of the beverage coming out of the slot 70 will not hit immediately on the upper surface of the flange 47 in the vicinity of the inlet 71 for air.

As in the first embodiment, the inner element 3 serves as the element which carries the load.

The Assembly procedure of the second variant of the cartridge 1 is similar to the Assembly in the first embodiment. However, there are some differences. As shown in Fig, the third section 21 of the cylindrical protrusion 18 is placed inside rather rotor rim 67 than the reference jumper. The shoulder 32 of the cylindrical protrusion 18 between the second portion 20 and the third section 21 rests on the upper edge of the support rim 67 of the inner element 3. Between the inner member 3 and outer element 2 is formed so area 124 of the passage that contains the mechanical seal between the cylindrical protrusion 18 and the supporting rim 67, running almost around the entire circumference of the cartridge 1. The seal between the cylindrical protrusion 18 and a bearing rim 67 is not impervious to the fluid, since the slit 70 in the bearing rim 67 passes through the bearing rim 67 and the bottom to the point, located directly under the shoulder 68. In the marginal fit between the cylindrical protrusion 18 and the supporting rim 67 turns the slot 70 in the hole 128, as shown best in Fig, providing a flow of gas and liquid between the annular channel 69 and videcnik pipe 43. The hole usually has a width of 0.64 mm and a length of 0,69 mm

The second version of the cartridge when the issue of the drink is similar to the operation in the first embodiment, but with certain differences. Drink in the radial passages 57 trickles down the passages 57 formed between the ridges 54 and through the openings 56 in the annular channel 69 of the cylindrical funnel 40. From the annular channel 69 beverage is maintained under pressure through the opening 128 through the back pressure of the drink going into the filter chamber 130 and the passages 57. The beverage thus passed under pressure through the opening 128 in the form of a strong jet and enters the expansion chamber formed by the upper end of wydanego pipe 43. As shown in Fig, a strong jet of the beverage passes directly over the entrance 71 for air. When the drink goes in vydatnou pipe 43, the pressure in the jet of the beverage falls. The result is the capture of the air jet of the beverage in the form of many small bubbles of air at the suction of air through the inlet 71 for air. A strong jet of the beverage coming out of the holes 128, goes down to the exit 44 from which the beverage is discharged into the receiver Cup type, in which the bubbles form the desired foam. Thus, the hole 128 and the inlet 71 for air together form the ejector, which serves to capture air drink. The flow of beverage into the ejector need to maintain as smooth in order to reduce pressure losses. Preferably, the walls of the ejector must be made concave in order to reduce losses associated with friction due to the boundary effect. The tolerances on the dimensions of the holes 128 are small. Preferably, the opening set with a deviation of plus or minus 0,02 mm Inside or at the outlet of the ejector may be provided hairs, thin fibers or other surface irregularities to increase the effective cross-sectional area, which can enhance the degree of trapping air.

On Fig-29 shows a third variant of the cartridge 1. The third variant of the cartridge 1 is designed specifically for use in the issuance of soluble products which can be in the form of powder, liquid, syrup, gel, or similar form. Soluble product is dissolved in an aqueous medium such as water, or form it suspended during the passage of the water environment in use through the cartridge 1. Examples of beverages include chocolate, coffee, Molo is about, soup or other dehydrated or water-soluble products. Many features of the third version of the cartridge 1 are the same as in previous versions, and to indicate the same characteristics are used in the same numerical position. In the further description will discuss the differences between the third and previous versions. Common signs of acting in the same way, be considered in detail will not.

As shown in Fig, compared with the outer element 2 according to the previous variants, hollow facing the inside of the cylindrical protrusion 18 of the outer element 2 according to the third variant has a larger outer diameter. In particular, the diameter of the first section 19 is typically from 16 to 18 mm, compared with a 13.2 mm for outer element 2 on the previous versions. In addition, the first section 19 provided with a convex outer surface 19a or swelling, as most clearly shown in Fig, the function of which will be described below. However, the third diameter sections 21 of the cartridge 1 is the same, so the area of the shoulder 32 in the third embodiment, the cartridge 1 is longer. Usually the volume of the cartridge 1 in the assembled condition is 32.5 ml ± 20%.

Different quantity and arrangement of the slits in the lower end of the annular wall 13. Apply 3 to 5 slots. In the embodiment shown in figure 2, around the circumference of the pipe 16 intervals are four slits 36. The slit 36 is slightly wider than in previous versions of the cartridge 1, having a width of 0.35 to 0.45 mm, preferably of 0.4 mm

In other respects, the outer elements 2 cartridges 1 are the same.

The design of the cylindrical funnel 40 of the inner element 3 is the same as in the first embodiment of the cartridge 1 with the outer pipe 42, videcnik pipe 45, the annular flange 47 and the supporting ridges 49. The only difference is that vydatnou pipe 45 provided with a top section 92 in the form of a truncated cone and the lower cylindrical section 93.

Unlike previous versions, and as shown in Fig-28, the annular frame 41 is replaced by the item in the form of a skirt 80 which surrounds the cylindrical funnel 40 and is connected by eight radial arms 87 which are located adjacent the cylindrical funnel 40 on the annular flange 47 or near it. A cylindrical protrusion 81 of the skirt 80 moves upward from the bracket 87 to limit the camera 90 with an open upper surface. As shown in Fig, the upper rim 91 of the cylindrical projection 81 has a curved inside the profile. The annular wall 82 of the skirt 80 moves downward from the bracket 87 to limit the annular channel 86 between the skirt 80 and the outer pipe 42.

The annular wall 82 soda is incorporated at the lower end of the flue to the outside of the flange 82, located perpendicular to the main axis X. the Rim 84 moves downward from the lower surface of the flange 83 and contains five holes 85, spaced intervals around the circumference of the rim 84. Thus, the rim 84 provided with indented bottom profile.

Between brackets 87 are formed openings 89, providing communication between the chamber 90 and the annular channel 86.

As in the first embodiment, the inner element 3 serves as the element which carries the load.

The Assembly procedure of the third variant of the cartridge 1 is similar to the Assembly in the first embodiment, when there are some differences. The outer element 2 and the inner element 3 is tightly connected together, as shown in Fig, and held together by a mechanism fit snap, not welding. When connecting two elements facing the inside of the cylindrical protrusion 18 is inside the upper cylindrical protrusion 81 of the skirt 80. The internal element 3 is held in the outer element 2 by frictional engagement of the convex outer wall 19a of the first section 19 of the cylindrical protrusion 18 with a curved inside rim 91 of the upper cylindrical protrusion 81. When the inner element 1, located in the outer element 2, there is formed a mixing chamber 134, located on the outside of the skirt 80. The mixing chamber 134 contains ingredients 200 drink before cooking. When eduit be noted, what four inputs 36 and five holes 85 are circumferentially staggered relative to each other. The radial location of the two parts relative to each other should not determine or fix during Assembly, because the use of two inputs 36 and five holes 85 guarantees the absence of alignment between the inputs and holes regardless of the relative rotational component installation. You can establish any number of input and output holes, which is determined by the formula

Xo=Xi+C

where Xi= the number of entrance holes,

Xabout= the number of output holes,

C = the set of integers excluding 0 or nXi,

n = any integer.

On the other hand, around the circumference of the cartridge can accommodate the same number of input and output holes through unequal intervals, which ensures that no combination of inputs and outputs.

In the mixing chamber 134 of the cartridge pack one or more beverage ingredients. The packing density of the beverage ingredients in the mixing chamber 134 can be varied as desired.

Then to the outer element 2 and the inner element 3 as described above for previous versions, attach the laminated material 5.

When using water enters specialno the chamber 134 through four slits 36 in the same manner as in previous versions of the cartridge. The water pumped in the radial direction inside through the mixing chamber and mixed with the contained ingredients of the drink. The product is dissolved or mixed in water to form in the mixing chamber 134 drink, which then disperses through the holes 85 in the annular channel 86 under the influence of the back pressure of the beverage and water in the mixing chamber 134. Accommodation circumferentially staggered four input slots 36 and five holes 85 ensures that a strong jet of water can not pass radially directly from the input slit holes 36 to 85, without circulation in the mixing chamber 134. Thus significantly increasing the degree and uniformity of dilution and mixing. Drink diverted upwards into the annular channel 86 through holes 89 between the brackets 87 and into the chamber 90. Drink passes from the chamber 90 through the inputs 45 between the support ridges 49 vydatnou pipe 43 and in the direction of exit 44, from which the drink is produced in the receiver Cup style. The cartridge is particularly suitable for use with the beverage ingredients in the form of viscous liquids or gels. In one of the applications in the cartridge 1 contains the ingredient in the form of liquid chocolate with a viscosity of from 1700 to 3900 MPa at ambient temperature and from 5,000 to 10,000 MPa at a temperature of 0°C, and prelolas the solids 67 Brix ± 3. In other applications in the cartridge 1 contains liquid coffee with a viscosity of from 70 to 2000 MPa at ambient temperature and from 80 to 5000 MPa at a temperature of 0°C, but the coffee has a total content of dry matter at the level of from 40 to 70%. Ingredient liquid coffee can contain from 0.1 to 2.0 wt.% sodium bicarbonate and preferably from 0.5 to 1.0 wt.%. Sodium bicarbonate is used to maintain the pH of coffee at the level of 4.8 or lower, providing the increase shelf life filled with coffee cartridges up to 12 months.

On Fig-34 shows a fourth variant of the cartridge 1. The fourth variant of the cartridge 1 is designed, in particular, for use in the issuance of liquid products, such as concentrated liquid milk. Many features of a fourth variant of the cartridge 1 are the same as in previous versions, and to indicate the same characteristics are used in the same numerical position. In the further description will discuss the differences between the fourth and previous versions. Common signs of acting in the same way, be considered in detail will not.

The outer element 2 has the same construction as in the third embodiment of the cartridge 1, and as shown in Fig-23.

The cylindrical funnel 40 of the inner element 3 such as that shown in the second embodiment of the cartridge 1, but with some differences. It is shown to Fig, vydatnou pipe 43 provided with a top section 106 in the form of a truncated cone and the lower cylindrical section 107. On the inner surface wydanego pipe 43 is made of three axial ribs 105, designed to guide issued by the drink in the direction of exit 44 and prevent turbulences issued beverage in the nozzle. The resulting edges 105 serve as partitions. As in the second embodiment of the cartridge 1 input 71 for air made in the annular flange 47. However, a pipe 75 under the inlet 71 for air more elongated than in the second option.

Similarly, the third version of cartridge 1 described above, it is proposed skirt portion 80. In the rim 84 has from 5 to 12 holes. Usually instead of five holes provided for the third variant of the cartridge 1, it is envisaged ten holes.

Provided by the annular Cup 100, extending from the flange 83 of the skirt 80 and forming with it one whole. Annular Cup 100 has a socket 101 with a top opening 104, facing up. Four feeding holes 103 shown in Fig and 31 and are located in the body 101 at the lower end of the bowl 100, or near it, where it connects with the skirt 80. Preferably, the feeding holes are spaced intervals around the circumference of the bowl 100.

As in the first embodiment, the inner element 3 serves as the element which carries the load.

Laminated material 5 refers to the type described above in previous versions of the runtime.

Operation of the fourth version of the cartridge is similar to the operation of the third option. Water enters the cartridge 1 and the mixing chamber 134 as previously. Here the water is mixed with the liquid product and dilutes it, whereupon he is given below of the bowl 100 and through the holes 85 in the direction of exit 44, as described above. Portion of the liquid product, originally contained in the circular bowl 100, as shown in Fig not immediately subjected to dilution with water in the mixing chamber 134. Most likely diluted liquid product in the lower portion of the mixing chamber 134 will tend to exit through the holes 85 instead of go up and ring the Cup 100 through the top opening 104. In the liquid product in an annular Cup 100 will remain relatively concentrated in the initial stages of the business cycle compared with the product in the lower portion of the mixing chamber 134. A liquid product in an annular Cup 100 seeps through the feeding holes 103 under the influence of gravity in the product stream leaving the mixing chamber 134 through openings 85 and under the Cup 100. Ring bowl is used to equalize the concentration of the diluted liquid product flowing in the cylindrical funnel 40 through which Ameriki part of the concentrated liquid product and a gradual issuance of its channel to the waste liquid stream as shown in figa, in which the concentration of milk is measured as the percentage of dry matter during the working cycle duration of approximately 15 seconds. Line "a" shows the concentration profile of Cup 100, while line b shows the cartridge without the bowl 100. You can see that the concentration profile in the presence of the bowl 100 during the working cycle is more uniform and is not observed sharp drop in concentration at the beginning, as occurs in the absence of the bowl 100. The initial concentration of milk is usually 30-35% SS (on dry matter), and at the end of the cycle it is 10% SS. This leads to a dilution ratio of approximately 3 to 1, although the invention are possible factors of dilution from 1 : 1 to 6 : 1. For other liquid beverage ingredients, the concentration may vary. For example, in the case of liquid chocolate initial concentration of approximately 67% SS, and at the end of the cycle 12-13% SS. The result is the dilution factor (ratio of aqueous medium to the ingredient of the drink in issued by the drink) on the order of 5 to 1, although the invention is possible dilution factors from 2 to 1 to 10 to 1. In the case of liquid coffee initial concentration is 40 to 67%, and the concentration at the end of the issue 1-2% SS. The result is a dilution ratio of 20 : 1 to 70 : 1, although the image is the shadow of possible ratios of dilution from 10 to 1 to 100 to 1.

From the annular channel 86 of the beverage is maintained under pressure through the opening 128 through the back pressure of the drink going into the filter chamber 134 and the chamber 90. The beverage thus passed under pressure through the opening 128 in the form of a strong jet and enters the expansion chamber formed by the upper end of wydanego pipe 43. As shown in Fig, a strong jet of the beverage passes directly over the entrance 71 for air. When the drink goes in vydatnou pipe 43, the pressure in the jet of the beverage falls. The result is the capture of the air jet of the beverage in the form of many small bubbles of air at the suction of air through the inlet 71 for air. A strong jet of the beverage coming out of the hole 128 is sent down to the exit 44 from which the beverage is discharged into the receiver Cup style, where the bubbles form required spumescence.

Preferably, the inner element 3, the outer element 2, the laminated material 5 and the filter 4 can be easily sterilized, because the components can be separated and do not contain individually winding passages or narrow slits. The required passages are formed instead only after connecting components after sterilization. This is especially important in the case when ingredient of the drink is a product based on milk, such as liquid end of the spending milk.

The fourth embodiment of the cartridge for a drink especially convenient for the issuance of the concentrated liquid dairy product, such as liquid milk. However, in the drink type cappuccino need to foam the milk. Previously this was achieved by passing steam through the liquid dairy product. However, it requires steam, which increases the cost and complexity of machines used for the issuance of a drink. The use of steam also increases the risk of injury during operation of the cartridge. Accordingly, the present invention provides for a beverage cartridge, which contains the concentrated liquid product based on milk. Found that the concentration of the dairy products it will produce more foam per a certain amount of milk compared with fresh or pasteurized milk. This reduces the size required for dairy cartridge. Fresh semi-skimmed milk contains approximately 1.6% fat and 10% solids. Concentrated liquid milk according to the invention contains from 0.1 to 12% fat and 25-40% of dry substance. In a typical example, the refill contains 4% fat and 30% dry matter. Refills concentrated milk suitable for foaming using preparatory machines low pressure, as will be described below. In particular, spin the of milk is achieved under pressure below 2 bar, preferably, approximately 1.5 bar using cartridge fourth scenarios described above.

Foaming the concentrated milk is especially important for drinks such as cappuccino and milk shakes. Preferably, the pass milk through the hole 128 and above the entrance 71 for air with the additional use of the bowl 100 allows to achieve the level of foaming milk more than 40%, preferably more than 70%. For liquid chocolate possible level of foaming over 70%. For liquid coffee possible level of foaming over 70%. The level of spanelement measured as the ratio of the volume of the resulting foam to the volume issued by the liquid ingredient of the drink. For example, in the case of the issuance 138,3 ml of the drink, which 58,3 ml - foam, foaming measured as [58,3/(138,3-58,3)]X100=72,9%. Foaming milk (and other liquid ingredients) is improved through the use of the bowl 100, as shown in fig.35b. Foaming milk, issued in the presence of the bowl 100 (line a)is higher than that of milk issued without bowls (line b). This is due to the fact that the foaming milk is positively correlated with the concentration of milk and, as shown in figa, the Cup 100 supports a higher concentration of milk during the greater part of the working cycle. It is also known that the foaming milk is positively correlated with temperature in the same environment, as shown in figs. Thus, the Cup 100 is an advantage, since most of the milk is left in the cartridge until almost the end of the working cycle, when the aquatic environment is the most hot. It also helps to improve spanelement.

The cartridge according to the fourth variant execution also has the advantages of issuing liquid coffee products.

Discovered that embodiments of the cartridge for beverages according to the invention have the advantage that they provide improved uniformity issued beverage in comparison with the known cartridges. Below table 1 shows the results of the exit of the drink for twenty samples for each of the cartridges a and b, containing roasted and ground coffee. The cartridge And the cartridge is for beverages according to the first variant implementation of the present invention.
