The present invention relates to a cartridge designed for the preparation of drinks and containing one or more ingredients to prepare drinks.

The use of foamed milk for making beverages such as coffee, cappuccino, is known. Usually foamed milk is received by use of the steam tube for directing a jet of steam into the container of milk. It still is the main method of obtaining foamed milk in commercial structures. It is desirable to be able to prepare drinks in style cappuccino at home. However, at home it is inconvenient to use creating a steam jet equipment, because if used improperly, it can be dangerous and difficult to clean. This is particularly disadvantageous in the case of equipment used with milk and require thorough cleaning to prevent contamination.

Cartridge for household machines for preparing beverages that are suitable for the preparation of foamed milk, disclosed in EP 1716055. Foamed milk is received within the cartridge by providing capture air flow of milk. The purpose of this invention is to provide an improved cartridge for the preparation of foamed beverages, in particular foamed milk-based drinks.

With therefore, its, the present invention relates to a cartridge containing one or more beverage ingredients and the specified cartridge contains:

an inlet for introducing an aqueous medium into the cartridge;

the outlet for the beverage made from the specified one or more beverage ingredients;

the hole in the duct for a drink, which connects the inlet and the outlet, creating while using a jet of the beverage;

the expansion chamber located downstream from the hole, and the expansion chamber contains an inlet expansion chamber for receiving the jet of beverage and outlet of the expansion chamber; and an inlet for air, located in the expansion chamber near the inlet of the expansion chamber;

moreover, the cross-sectional area of the expansion chamber decreases in the direction downstream from the inlet of the expansion chamber to the outlet of the expansion chamber, and the cross-sectional area and profile of the outlet of the expansion chamber is essentially the same as the cross-sectional area and the flow profile of the beverage as it passes through the hole.

The characteristic shape of the expansion chamber is an effective tool to capture air flow to IDA as it passes through the expansion chamber. The reduced cross-sectional area of the expansion chamber in the exhaust outlet of the expansion chamber ensures the prevention of the absorption of the drink back into the expansion chamber instead of air, which would reduce the efficiency of suction of air from the atmosphere. Improved design provides increased foamed beverage compared to previously known ink cartridges.

Preferably the cross-sectional area of the inlet of the expansion chamber is greater cross-sectional area, creating a jet holes.

In particular, a relatively large cross-sectional area of the expansion chamber in the immediate vicinity of the inlet for the air provides a relatively large volume of low pressure around the incoming jet of the beverage, thereby providing a relatively easy entry of air into the expansion chamber.

Preferably the bottom wall and the top wall of the expansion chamber converge to each other in the direction down the stream.

Expansion chamber may contain are located opposite each other, side walls, and side walls may converge in the direction down the stream.

Preferably the hole is located so that the jet of the beverage produced from the hole, passes from the inlet EXT is tion chamber into the outlet of the expansion chamber is essentially no interaction with the lower wall of the expansion chamber.

More preferably the hole is located so that the jet of the beverage produced from the hole, passes from the inlet of the expansion chamber at the outlet of the expansion chamber is essentially no interaction with one or more side walls of the expansion chamber.

Preferably the inlet air hole made in the bottom wall of the expansion chamber.

Preferably the inlet air contains an elongated slot.

Preferably oblong slot is perpendicular to the direction of flow of the jet of the beverage produced from the hole.

According to one preferred aspect of the mixing chamber includes an outlet opening that communicates with the outlet of the cartridge and the mixing chamber further comprises a set of protrusions located at some distance from each other around the outlet of the mixing chamber.

Preferably the protrusions are arranged around the first part of the periphery of the outlet of the mixing chamber, and a second portion of the periphery of the outlet of the mixing chamber does not contain protrusions, and the second part of the periphery coincides with the outlet of the expansion chamber and has such dimensions that a jet of the beverage produced in the time what I use from the outlet expansion chamber, could enter the Central region of the mixing chamber without prior collision with the tabs.

The protrusions can be located on the arc. Preferably the tabs are located along the arc of a circle.

Preferably the cartridge contains from 3 to 20 tabs.

Preferably the tabs function to reduce areas of stagnant flow within the mixing chamber during use. The tabs provide no open spaces in which the flow of the drink may become relatively "standing". It was found that such "standing" area facilitate cholesterolemia small air bubbles in undesirable large air bubbles. The tabs allow you to eliminate this problem by separating flows within the mixing chamber to create a turbulent flow on a smaller scale, preventing cholesterolemia bubbles, unlike the vortex flow on a larger scale, contributing to cholesterolemia bubbles. Thus, the resulting foam has better quality compared with foam foamed beverages prepared using previously known ink cartridges.

One or more beverage ingredients can be liquid ingredients. One or more beverage ingredients can be liquid ingredients based on milk, such as the liquid is anantanubandhi milk. Liquid milk can be pasteurized or sterilized by known methods, such as high-temperature processing, instant pasteurization, sterilization autoclave, etc.

Preferably the cartridge is sealed before use in a machine for preparing beverages with the aim of making the drink.

Figure 1 shows the known from the prior art cartridge 1 described in the applicant's earlier European patent with publication number EP 1716055. For a complete description of the cartridge 1 the reader should refer to the description of the document EP 1716055, which is incorporated herein by reference. Hereinafter will be described in detail only those parts of the cartridge 1, which relate to the present invention.

The cartridge 1 according to EP 1716055 usually contains a foreign element 2, the inner element is 3 and the cover 5 of the multilayer material. The outer member 2, inner element 3 and the cover 5 of the multilayer material collected with the formation of the cartridge 1 containing chamber 134 for storing one or more ingredients 200 drink, an inlet opening (not shown), the outlet duct 122 and to drink, connecting the inlet with the outlet 122.

The internal element 3 contains the discharge port 43 surrounded by the outer tube 42 attached to the exhaust pipe 43 through the annular flange 47. The internal element 3 also contains part 80 in the form of a skirt that engages with the outer pipe 42 by means of the ribs 82 of the skirt. The annular channel 69 is formed between the inner wall portion 80 in the form of a skirt and the outer wall of the outer tube 42. The annular channel 69 contains the lower part 69L, below the ribs 87 skirt, and the upper part 69U above the edges 87 of the skirt. The space between the ribs 87 provide a hydraulic connection between the lower part 69L and the upper part 69U annular channel 69. And, finally, part 80 in the form of a skirt of the inner element 3 contains the Cup 101 to regulate the mixing of the ingredient of the drink.

Duct, through which the beverage passes through the chamber 134, the annular channel 69 and the discharge port 43, as will be described in more detail below.

The inlet and outlet 122 is initially sealed akriti cover 5 of the multilayer material, and while using open them through the perforation or cutting of the cover 5 of the multilayer material. Duct ask for a drink by the spatial relative position of the outer member 2, inner element 3 and the cover 5 of the multilayer material. In the cartridge 1 can optionally include other components such as a filter.

Different types of cartridge disclosed in EP 1 716 055, can be used for dispensing roasted and milled products or liquid products, such as concentrated liquid milk. In addition, it is possible to perform dispensing liquid coffee products.

A special advantage of cartridges presented on Fig and 34 EP 1716055, is to provide means, for example, in the form of eductor, for trapping air in the drink. Used herein, the term "eductor" refers to the use of holes or similar structures for the formation of a jet of the beverage, and the hole is located in the duct for a drink upstream from the inlet for air and an expansion chamber, and the specified hole placed for the formation of a jet of the beverage, which is injected into the expansion chamber to create a zone of low pressure near the inlet for the air, which causes suction of air through the inlet to ozdoba and capture air jet of the beverage.

As shown in figure 1 (based on Fig document EP 1716055), on the inner element 3 is designed rim 67, protruding upwards from the annular flange 47 which connect the outer pipe 42 from the outlet 43. Rim 67 surrounds the inlet 45, leading to the exhaust pipe 43. Rim 67 is equipped directed inward flange 68. In one position on the perimeter of the rim 67 is made a slot 70, and a slot extends from the upper edge of the rim 67 to a position located slightly below the level of the Board 68.

The inlet 71 for air made in the annular flange 47 and aligned circumferentially with slot hole 70. The inlet 71 is a hole passing through the flange 47 so as to provide communication between the position above the flange 47, and the free space below the flange 47 between the outer tube 42 and the outlet 43. The inlet 71 for air contains the upper part in the shape of a truncated cone and the lower cylindrical part. The wall of the outer tube 42 near the inlet 71 for air characterized by this form, to form a trench passing from the inlet 71 for air to the inlet 45 of the exhaust pipe 43.

Three axial ribs 105 are made on the inner surface of the exhaust pipe 43 is La direction dosed drink down to the outlet 44 with the to help collect metered drink in a relatively narrow controlled stream.

As shown in figure 1, when the cartridge is assembled, the cylindrical protruding portion 18 of the outer member 2 is planted in the rim 67. The cylindrical protruding portion 18 is essentially closes the inlet 45 of the exhaust pipe 43, including the closure of the upper end of the slot 70. Since a slot 70 in the rim 67 passes below the level of Board 68, the hole 128 remains open to provide flow through the annular flange 47. Thus, in an assembled condition, a slot 70 is designed to be a hole 128 is approximately in the shape of a rectangle.

During use of the cartridge 1 is inserted into the machine for preparing beverages and an inlet opening and an outlet opening 122 open with the help of these elements of the machine for preparing beverages perforined and bend the cover 5 of the multilayer material. Aqueous medium, typically water, under pressure enters the cartridge 1 through the inlet and is directed flows into the chamber 134. The water pump on the channel for a drink through the chamber 134 and mixed with contained in the cell ingredients 200 drink. At the same time water is pumped up through the ingredients of the drink.

Backpressure beverage is, collected in the chamber 134, pumps the beverage under pressure through the opening 128 extending in the form of a jet into the mixing chamber 49 at the upper end of the exhaust pipe 43. A jet of the beverage passes directly over the entrance hole 71 for air. At the entrance of the drink in the chute and the inlet 45 of the exhaust pipe 43, the pressure of the jet of the beverage falls. The result is the capture of air into the flow of the beverage in the form of many small bubbles of air at the suction of air through the inlet 71 for air. A jet of the beverage coming out of the holes 128, turbulent flows in the chamber 49 mixing, before going down to the outlet nozzle 44, where the production of the beverage in a container such as a Cup into which the air bubbles will form the desired foam.

Figure 2 and 3 shows in perspective of the cartridge that contains another internal element 3' in accordance with the prior art. Many of the characteristics of the internal element 3' is similar to that described above with respect to the inner element 3, and similar digital signs have been used to refer to such signs.

The internal element 3' is different from the internal element 3 on the shape and size of eductor, and that further comprises a partition wall 65 in the lower part of the exhaust pipe 43. The partition wall 65 provides prevention R is spalania and/or splashing of the beverage as it comes out of the exhaust pipe 43. In addition, the internal element 3' does not contain a bowl 101.

As best represented in figure 3, eductor this cartridge contains an elongated trough 300, made in the inner element 3'. Gutter 300 includes the lower surface 302, the side walls 303 and located upstream wall 304. Gutter 300 further comprises a socket 290, located in located downstream end of the chute 300 and communicated with the chamber 49 of the mixing. Slotted groove 70 eductor combined with trench 300 so that the groove formed duct from the opening 128 (formed from the slot 70 when the cartridge Assembly to the chamber 49 of the mixing. The inlet 71 for air communicates with the groove 300 and executed in its bottom surface 302 located near upstream end of the gutter 300.

The cross-sectional area of the gutter 300, that is, the internal cross-sectional area perpendicular to the flow direction and parallel located upstream wall 304, gradually increases in a direction downstream from above the flow wall 304 to the socket 290 of the gutter 300. Thus, the cross-sectional area of the socket 290 larger cross-sectional area of the gutter 300 close located upstream wall 304 and the inlet 71 for air. A gradual increase in cross-sectional VC is BA 300 reach through the bottom surface 302, characterized by a gradual slope down from above on the flow wall 304. The side walls 303 are essentially parallel, resulting in the width of the gutter 300 will not change along the length. While using the trench 300 is closed along its top by the bottom surface 31 of the cylindrical protruding part 18 when the cartridge 1 is in the assembled state. Thus, the trench 300 forms an expansion chamber downstream from the hole 128.

While using a jet of the beverage out of the hole 128 and is in the gutter 300. The inlet 71 to flow inside of the gutter 300 so that it corresponded with the area of low pressure created by the jet. Since the inlet 71 for air communicates with the atmosphere, there is an intake of air through the inlet 71 for air and capture the air passing by the flow of the drink. The flow of the beverage flows through the chute 300 and then enters the chamber 49 of the mixing, which is further mixing of trapped air and drink as long as they are not released from the cartridge through the outlet 44.

Known from the prior art cartridges containing the above-described inner chamber 3 and 3', has been used successfully in home machines for preparing beverages with the aim cooked what I foamed beverages, such as espresso, cappuccino coffee and foamed milk-based drinks. To further improve the quality of the foam according to the present invention was developed advanced internal element 3" (described in more detail below). Improved internal element 3 constitutes a larger volume of foam, characterized by a more constant size smaller air bubbles.

Figs.4 and 5 show views in perspective of the improved inner element 3", forming part of the improved cartridge according to the present invention. Some of the symptoms of inner element 3", similar to that described above in relation to the internal element 3 and 3', and similar digital signs have been used to refer to such signs.

The internal element 3" is similar to the opened top of the inner element 3', except for the addition of protrusions 400 in the chamber 49 mixing, (optional) remove the edges 105 of the exhaust pipe 43 and modification of eductor. In addition, instead of part 80 in the form of a skirt of the inner element 3", attached to the outer tube 42 by means of ribs 87 skirt, use part 80 in the form of a skirt of the inner element 3", attached to the outer tube 42 by means of flanges 87' skirts.

As best represented in figure 4 and 6, the Board 87' skirt contains is usesto continuous ring, the surrounding outer pipe 42. Board 87' skirt contains a hole (not shown), combined with a slit aperture 70 in the annular rim 67. The hole in the Board 87' skirt provides a hydraulic connection between the lower part 69L annular channel 69 and slot hole 70. Two guides the flow of walls 320 are located on each side of the holes in the Board 87' skirts. Directing the flow of walls 320 are held between the inner wall portion 80 in the form of a skirt and the rim 67 of the outer tube 42 to create zheloboobraznogo directing the flow channel 321. As shown in Fig.7, while using the upper part 69U annular channel 69 containing the guide flow channel 321 is closed along its top by the bottom surface 31 of the cylindrical protruding part 18 when the cartridge 1 is in the assembled state.

As best represented in figure 5, a slot 70 of the inner element 3" is reported to contain parallel sides of the groove 310 leading to the inlet of the expansion chamber 305 with the formation of the zone of expansion. Expansion chamber 305 contains located upstream wall 308, two side walls 307 and the lower surface 306 or lower wall. Expansion chamber 305 further comprises an outlet opening 309, located in located downstream end will expand the school camera 305, which communicates with the chamber 49 of the mixing. While using expansion chamber 305 is closed along its top by the bottom surface 31 of the cylindrical protruding part 18 when the cartridge 1 is in the assembled state. Thus, the expansion chamber 305 is located downstream relative to the openings 128.

Expansion chamber 305 is characterized such that the cross-sectional area, i.e. the cross-sectional area perpendicular to the flow direction and parallel located upstream wall 308, the input apertures substantially larger cross-sectional area, creating a stream of groove 310. In addition, the cross-sectional area of the outlet 309 the expansion chamber 305 is less than the cross-sectional area near the inlet of the expansion chamber 305, parallel located upstream wall 308, located near the upstream wall 308 and the inlet 71' for air. This reduction in cross-sectional area is preferably achieved by means of side walls 307, gradually converging along the length of the chamber 305 so that the width of the camera 305 decreased along its length, and/or with the bottom surface 306 passing tilted upward from the bases located upstream wall 308 to output the at the hole 309 (see 6 and 7) so that the height of the camera 305 is gradually decreased along its length.

As shown in figure 5, an inlet for air is made preferably in the form of an elongated slot 71' in basis located upstream wall 308 of the expansion chamber 305 so that a slot 71' lay at the base of the expansion chamber 305. A slot 71' is width through the expansion chamber 305 and ends, not reaching both side walls 307, as shown in figure 5. The inlet 71' for air is immediately after located upstream wall 308 and downstream from it so that it was as close as possible to the position where the jet of the beverage coming out of the holes 128, enters the expansion chamber 305. This ensures that the inlet 71' for air situated in an area of very low pressure in the expansion chamber 305. It provides optimized pressure drop through the inlet 71' for air and, thus, the quantity of air sucked through the inlet 71' for air. The inlet 71' to air can have any desired shape. However, it was found that the inlet for air in the form of an elongated slot is site is titanium, because it allows you to position the input air hole located closer to the upstream end of the expansion chamber 305, than known from the prior art, the inlet for air, and at the same time also allows you to perform an inlet for air to the increased size in comparison with the known prior art constructions. In addition, the elongated slot allows you to use a more durable tool for molding as compared with the rod molds, characterized by a small diameter.

The reduced cross-sectional area of the outlet 309 the expansion chamber is shaped in the form of holes mailbox, characterized by a relatively large width and small height.

The discharge port 43 forms the outlet 44 of the cartridge. The inlet 45 of the exhaust pipe 43 is specially formed as a Central bore in the bottom wall of the chamber 49 of the mixing. As most clearly represented in figure 4, many of the projections 400 performed in the chamber 49 of the mixing surrounding the inlet 45 of the exhaust pipe 43. The protrusions 400 are made in the sloping shape of a truncated cone to facilitate the forming process.

The protrusions 400 so located in the chamber 49 of the mixing that they surround the first frequent the 403 periphery of the inlet 45, passing to the outlet 43. The second part of the periphery of the inlet 45, passing to the outlet 43, contains no protrusions 400, so that the second portion of the periphery of the forming zone 405 entrance region 406 that is located essentially in the region, limited to the first part of the periphery 403. The protrusions 400 are located so that the area of 405 entrance is located essentially transversely of the socket 309 expansion chamber 305. Thus, during use of the beverage coming out of the expansion chamber 305 through the socket 309, initially will not encounter interference when the entrance to the chamber 49 of the mixing.

The protrusions 400 are placed in an arc. Preferably, the arc is part of a circle. Made six protrusions 400. The protrusions 400 protrude from the bottom wall of the chamber 49 of the mixing and are free-standing so that they are not in contact with the upper wall.

During use, the cartridge is installed in a machine for preparing beverages and water are injected into the cartridge as described above. According to the above jet of the beverage, such as a drink based on milk coming out of the holes 128 and enters the expansion chamber 305. An area of low pressure creates the vicinity of the inlet 71' for air, and this causes the trapping air, which is sucked through a slot, which is the inlet 71' for air, proh who administers the flow of drink.

The configuration of the expansion chamber 305 creates a flow regime inside the cartridge, which helps to capture the flow of drink a larger volume of air compared with the known prior art cartridges. In particular, the expansion chamber 305 is configured so that during use of the jet of beverage included in the expansion chamber 305 through creating a jet groove 310, is faced with an immediate large (in relation to the sectional area of flow of the jet) expanding cross-sectional area of flow in the inlet of the expansion chamber 305. At the exit of the jet of beverage from creating a jet groove 310 is its expansion in the width and height. The cross-sectional area of flow of the beverage increases in a downward direction along the flow as it approaches the outlet 309 the expansion chamber 305. The hole 309 is characterized in such a size that the cross-sectional area and profile of the outlet 309 essentially the same cross-sectional area and the flow profile of the drink in located downstream end of the expansion chamber 305 (i.e. at the outlet 309). In addition, since the flow of the beverage has a smaller cross section of flow in relation to the cross-sectional area of the expansion chamber 305 than in the known prior technology is key-systems more flow drink surrounded by air at least located upstream end of the expansion chamber 305. Thus, more air can be captured by the flow of the drink, because the air can pass around all or most of the perimeter of the flow of the drink. This effect is enhanced by performing the shape of the inlet 71' to air in the form of a slotted hole, occupying the whole area of the inlet for air in the zone of lowest pressure.

This effect is additionally enhanced due to the inclination of the jet of liquid to be attracted to a nearby surface (the Coanda effect), namely the lower surface 31 of the outer member 2, which functions as the upper wall of the expansion chamber 305 (see Fig.7). Thus, when passing through the expansion chamber 305, the flow of the beverage will strive to adhere to the surface 31 and dissipate it. This cannot be achieved in the known prior art cartridges, in which the expansion chamber is narrower and the side walls of the expansion chamber, thus, affect the dynamics of flow flow of the drink.

Since the cross-sectional area and profile of the inlet 309 essentially the same cross-sectional area and profile sweat the ka drink in the input hole 309, basically prevents re-entry of air and/or drink into the expansion chamber 305 from the chamber 49 mixing under the influence of the flow of the beverage coming out of the expansion chamber 305. It was found that known from the prior art internal elements, such as described above element 3'inherent in the re-entry of air and/or drink in an area of low pressure near the inlet for air from the mixing chamber. This is undesirable, because the recirculated flow can partially block the inlet for air, preventing efficient air intake. This results in less air will be captured in the output stream.

It was found that the combination of the expansion chamber 305, characterized by the cross-sectional area of the inlet of greater cross-sectional area of the outlet 309, the outlet 309, characterized by the cross-sectional area and profile, essentially coinciding with the cross-sectional area of the flow and profile of the jet emerging from the expansion chamber, and the outlet 71' for air, located near the inlet into the chamber, provides a significant increase in the volume prepared foamed drink. The cross-sectional area of the inlet 309 is su is estu entirely the same, as the cross-sectional area of flow of the drink, because any large area will cause a reverse flow of the beverage from the mixing chamber, and any less will cause excessive splashing of the stream of beverage or the impact of a stream of beverage with surfaces of the expansion chamber and the return flow into the expansion chamber.

Expansion chamber does not necessarily have to consist of essentially flat walls, as described above with respect to the internal chamber 3". The configuration of the expansion chamber 305 of the internal element 3" is well suited for large-scale production. However, there may be applied any structure, characterized located upstream of the flow area, located more downstream cross-sectional area of flow, and the area of the outlet, essentially coinciding with the cross-sectional area of flow of the beverage in the exit hole.

The direction of the jet discharged from the openings 128, initially controlled by means of creating a jet groove 310 with parallel sides so that there is less sensitive to small deviations in the dimensions of parts or incorrect location. However, the groove 310 may be missing, resulting in a slot 70 is communicated directly with expansion chamber 305, passing cerebrospinal upstream wall 308. In addition, the bottom surface 306 of the expansion chamber 305 may be essentially perpendicular located upstream wall 308.

The flow of drink and trapped air out of the expansion zone 305 via the outlet port 309 in the chamber 49 of the mixing, in which he continues to mix. Since the zone 405 entrance located across the outlet 309 the expansion chamber 305, the flow of the drink does not encounter interference when entering the area 406, surrounded by the protrusions 400.

The protrusions 400 provide no open spaces inside the chamber 49 mixing without creating a large pressure drop. They also create a more uniform turbulent flow inside the chamber 49 of the mix and ensures the elimination of turbulence. This, in turn, ensures the prevention of cholesterolemia captured in the drink small air bubbles to large bubbles. Thus, the resulting foam has better quality than the foam obtained by means known from the prior art cartridges, because it contains less air bubbles with a more uniform size.

On figa and 9a presents the image of foamed milk drink made using a cartridge containing a known from the prior art internal element (takoyaki internal element 3 or 3'), and fig.8b and 9b presents images of foamed milk drink made using a cartridge containing an internal element according to the present invention. According to fig.8b and 8b, the amount of foamed milk drink made using a cartridge containing a known from the prior art internal element (figa), significantly less than the amount of foamed milk drink made using a cartridge containing an internal element according to the present invention (fig.8b).
