The present invention relates to a cartridge for preparing beverages, which contain one or more ingredients for the preparation of beverages.

The preparation of high-quality coffee drinks is well known in public cafeterias for many years. Over the years the methods of obtaining the coffee has improved and experts in the field of technology have learned to produce a better coffee drinks. Have seen strong growth, especially in the last 10 years, cafeterias, offering more specialized drinks such as espresso and cappuccino. These types of drinks have historically treated the luxuries because of the need to use expensive complex machines that can create the high pressure needed for their preparation. Such machines it is advisable to have work and to be served by trained baristas to obtain good quality.

Test consumers high quality coffee drinks have not only increased the requirements for high quality luxury drinks from the special cafeterias, but also entail the need for a greater variety of special drinks and the ability to create such drinks in a comfortable environment at home each person.

Domestic filter coffee machines have become widely available since the 1960s. However, such machines are not the way�s to produce coffee style related espresso or steamed milk required to prepare special drinks, such as cappuccino. Domestic coffee machines have advanced considerably since the introduction of the first filter machines and now occupy an important place in the bathrooms of many families. Of these machines give out individual servings of the drink directly into a drinking container and get a drink using a bulk supply of beverage ingredient or by individual packages of beverage ingredient, for example, bags, pads or cartridges. In the following further description of these packages will be referred to as the common expression is "cartridges". Machines that use these cartridges eliminate the need of cleaning and can allow the user to make a choice of drinks. An example of one type of such a cartridge is described in EP-A-1440903. These drinks are formed by boiling, mixing, dissolving or defending beverage ingredients in the water. For example, for coffee drinks heated water is passed through the cartridge for the formation of the extracted solution. The use of cartridges in such machines is becoming more popular due to their convenience and quality of the produced beverage.

Example of a machine for preparing beverages using this type of cartridge is described in EP-A-1440644. This type of machines� provided such an improvement of prior art, known at the time that she worked at lower pressures than previously known machines that were manufactured for the markets of industrial and commercial enterprises, and not the domestic market. As a result, this type was more appropriate in terms of cost, reliability, and availability for the domestic market.

Despite the achievements made in home coffee machines and the respective cartridges, there is an ongoing demand for coffee drinks, all best quality that can be easily prepared at home without the need for special equipment or training.

To allow the user to create drinks in a full range of styles "cafeterias" at home, not only it is necessary to provide a means for brewing high quality coffee types of espresso, but you also need to provide the user with means to obtain foamed milk to create drinks such as cappuccino. Traditionally, foamed milk produced in the cafeterias using the steam wand with the ability to direct the steam in a tank of milk. So far, this is the main method of producing foamed milk in a commercial environment. However, it is inconvenient to use the equipment to obtain a jet of steam at home, as it can be dangerous if not used�Xia correctly and can also be difficult to clean. This is a particular disadvantage for the equipment used with milk, which requires a thorough cleaning to prevent contamination.

An example of a cartridge for household machines for preparing beverages, which is suitable for the production of foamed milk, is known from EP-A-1716055. Frothed milk is made with the cartridge, causing the air to become included in a stream of milk that is created when water mixes with the concentrated dairy ingredient contained inside the cartridge. This is achieved by passing the milk through eductor inside the cartridge. Eductor contains a hole that is arranged to create a stream of milk. Stream milk passes through the air intake, causing the air to become included in the milk, thereby creating foamed milk. Foamed milk obtained by using such cartridges, allows to prepare drinks in style cafeterias, for example cappuccino, easily made at home without the need for potentially dangerous and difficult to clean equipment with a steam pipe. We must continue to improve like this cartridge, so as to further improve the quality of milk froth, which can be obtained at home.

Studies have shown that in BP�kitchen in processing and storage in a concentrated liquid dairy ingredient cartridges oblong formed agglomerated particles. These particles have the potential to block or partially block the hole, resulting in less air entering stream of milk. If this happens, the quality and quantity of milk froth can be adversely modified.

It is known to use filter cartridges for machines for preparing beverages to prevent solid particles from reaching the output of the cartridge and thus contamination of the beverage. For example, filters are usually used in the cartridges for getting coffee as described in EP-A-1440903 above. These filters contain many small holes that are smaller than the smallest size of filterable particulate. There is an effect of preventing fine solid particles from reaching the cartridge release. But also there is the effect of restrictions on the flow of the beverage through the cartridge when the dispersed ingredient of the beverage held in the near upstream of the filter face. Such restriction of flow is not appropriate in the cartridges used to produce foamed milk, as the restriction of the flow reduces the efficiency of eductor and, consequently, reduces the quality and quantity of the obtained foamed milk. This is directly different from the desired effect of improving the quality and quantity of foam.

In a first aspect the present invention provides ka�TRIG, containing one or more beverage ingredients, wherein the specified cartridge contains:

the inlet for introducing the aqueous medium into the cartridge;

edition for beverage derived from the specified one or more beverage ingredients; and

the flow path connecting the inlet with the release;

moreover, one or more beverage ingredients contains liquid ingredient of the drink and elongated particles of the beverage ingredient;

wherein the cartridge further comprises a filter located in the flow path, with the specified filter contains a plurality of holes, which have such dimensions that a significant proportion of elongated particles retained on the near end on the downstream side of the filter,

wherein the cartridge further comprises a hole located in the flow path downstream of the filter, wherein the opening is formed, in use, with the ability to produce a jet of the beverage, and the maximum area of each hole on the near upstream of the filter surface is not more than ten times larger than the area of the hole.

The filter prevents most elongated particles reach the farthest upstream of the side of the cartridge. This helps to prevent the blocking of particles or hindering work far upstream of the side of the cartridge. In particular, this helps to prevent the hole from freezing. Thus, CT�ridge is able to provide better and more repeatable results without having to change the composition of ingredients of the drink or the execution of a cartridge on the far during party.

When boiling milk, the holes preferably have a maximum size of 1.6 mm to the near upstream of the filter surface. The need to provide a suitable balance between maximizing the magnitude of elongated particles retained by the filter, and minimizing the violation of the fluid flow inside the cartridge.

More preferably, when preparations of milk, the holes have a maximum size of 1.0 mm to the near upstream of the filter surface to optimize the balance between maximizing the magnitude of elongated particles retained by the filter, and minimizing the violation of the fluid flow inside the cartridge. The maximum size of the near upstream of the filter surface may preferably be selected for a special drink with a balance of consistency and quality of the foam and the quantity of the ingredient that is retained in the cartridge.

In a preferred embodiment, the maximum area of each hole on the near upstream of the filter surface is not more than seven times larger than the area of the hole. Most preferably, the maximum area of each hole on the near upstream of the filter surface is not more than five times the area of the hole. The relationship between the size of the holes in the filter and the size of the far upstream of the orifice affects neveroyatnoi lock far upstream of the orifice.

Oblong particles of the beverage ingredient can be agglomerates of liquid ingredient of the drink. The liquid ingredient of the drink can be a liquid milk ingredient, such as concentrated milk. Liquid milk may be pasteurized or sterilized by known methods, such as UHT processing, instant pasteurization, distillation in the retort, etc.

In a second aspect, the invention additionally provides a method of producing a beverage from a cartridge containing one or more beverage ingredients, wherein the specified one or more beverage ingredients contains liquid ingredient of the drink and elongated particles of the beverage ingredient, the method contains the stages on which:

injected aqueous medium into the cartridge;

Fig. 1 shows a cartridge 1, is known from EP-A-1716055 which is also owned by the present applicant. The present invention represents an improvement over known cartridge, so the following describes only those parts of the cartridge 1, which belongs to the present invention.

The cartridge 1 contains an outer member 2, inner member 3 and the multilayer cover 5. The outer member 2, inner member 3 and the multilayer cover 5 are going to form the cartridge 1 which has a camera 134 to one or more of the ingredients 200 drink, the inlet 28 (see Fig. 2), issue 122, and the flow path of the beverage, connecting the inlet with the release of 122.

In the example of Fig. 1 the ingredients 200 drink is a concentrated liquid milk. Concentrated liquid milk 200 contains a mixture of concentrated fluid milk and oblong agglomerated particles of milk, which are formed in a concentrated liquid milk during processing and storage. Oblong agglomerated particles typically have a ratio of length to maximum width that is greater than 10.

The internal element 3 contains the discharge spout 43 is surrounded by the outer tube 42, which is connected to the discharge spout 43 of the annular flange 47. The internal element 3 also contains the skirt section 80, which is connected to the outer tube 42 at�CNAME ribs 87. Annular channel 69 is defined between the inner wall of the skirt section 80 and the outer wall of the outer tube 42. Annular channel 69 has a neighbor along the flow section 69U skirt below the ribs 87 and far upstream of the section 69D above the skirt of the ribs 87. The message on fluid between the middle along the flow of the plot 69U and far upstream of the section 69D annular channel 69 is provided by the distances between the ribs 87. Finally, the skirt section 80 of the internal element 3 contains the Cup 101 to regulate the mixing of the ingredient of the drink.

The flow path of the beverage passes through the chamber 134, the annular channel 69 and the discharge spout 43, as will be described in more detail below.

The inlet 28 and the release 122 are initially sealed by the laminate 5 and the use of punching or cutting of the laminate 5. The flow path of the beverage is determined by the mutual spatial relationship between the outer member 2, inner member 3 and laminate 5.

The cartridge can be adapted for different kinds of food, such as roasted and crushed products or liquid products, such as concentrated liquid milk. It is also possible to give the liquid coffee products.

A particular advantage of the cartridge of this type is that it is provided with means for introducing air into the beverage, for example, made�CSOs in the form of eductor. The expression "eductor" here refers to the use of holes or similar structures for the formation of the jet of the beverage, wherein the hole is located in the flow path of the beverage in front of the air inlet and expansion chamber, and said hole is arranged to generate a jet of beverage, which is produced in the expansion chamber to create a low pressure zone near the air intake, which causes the air to move through the air intake and becomes included in the jet of the beverage.

As shown in Fig. 1, the inner element 3 is provided with a rim 67, which protrudes upward from the annular flange 47 connecting the outer tube 42 with the discharge spout 43. The rim 67 surrounds the inlet 45 outlet of the spout 43. The rim 67 is provided with inward directed ledge 68. At one point around the periphery of the rim 67 is provided with the slit 70, the slit 70 extends from the upper edge of the rim 67 to a point slightly below the level of the ledge 68.

In the annular flange 47 is provided with an inlet 71 of the air circumferentially aligned with the slot 70. The inlet 71 of the air contains a hole passing through the flange 47 so as to provide communication between the point above the flange 47 and the empty space under the flange 47 between the outer tube 42 and an outlet nozzle 43. The inlet 71 of the air contains the upper portion having the shape of a truncated cone, and the lower �zylindrische plot. The external wall of the tube 42 near the inlet 71 of the air has such a shape to form the shutter 46, leading from the inlet 71 of the air in the intake 45 exhaust nozzle 43.

Three axial ribs 105 are provided on the inner surface of the exhaust nozzle 43 to the directions issued by the beverage down towards the release of 44, to help deliver issued by a drink in a relatively narrow, manageable stream.

As shown in Fig. 1, when the cartridge is collected, cylindrical elongation 18 of the outer element 2 is placed inside the rim 67. Cylindrical elongation 18 essentially closes the inlet 45 of the exhaust nozzle 43, including the closure of the upper end of the slit 70. Since the slit 70 in the rim 67 is continued below the level of the ledge 68, the hole 128 remains open to provide movement of fluid through the annular flange 47. Thus, when assembling the slit 70 is performed with the possibility becomes approximately square-shaped hole 128.

When using the cartridge 1 is inserted into the machine for preparing a beverage, wherein the inlet 28 and the release 122 is opened revealing the elements of the machine for preparing a beverage, which is perforated and folded laminate. Aqueous medium, usually water, under pressure enters the cartridge 1 through the inlet and is directed to flow into the chamber 134. Water is pumped along the flow path of the beverage che�from the camera 134 and mixes with the ingredients 200 drink sterilise in it. At the same time, water is pumped up through the beverage ingredient.

Counter pressure of the beverage, a gathering in the chamber 134 pumps the beverage under pressure through the opening 128, manifesting itself in the form of a jet into the mixing chamber 49 on the upper end of the discharge spout 43. The jet of beverage passes directly through the inlet 71 of the air. When the drink is included in the draining and inlet 45 outlet of the nozzle 43, the pressure of the jet of the beverage falls. As a result, air is introduced into the jet of the beverage in the form of a large number of small air bubbles as the air moves up through the inlet 71 of the air. The jet of the beverage coming out of the holes 128, turbulent flows in the mixing chamber 49 to pouring down through the discharge spout 44, from which a drink is thrown in a container such as a Cup where the air bubbles form the desired appearance of foam.

Fig. 2 shows a sectional view in perspective of the cartridge 1' with an internal element 300 according to the invention. Many of the symptoms of inner element 300 are the same as opisywanie above with reference to the internal element 3, as needed same reference position used to denote the same features. For clarity, in Fig. 2 shows the cartridge 1', not containing beverage ingredients. In addition, the cross section of Fig. 2 are provided so that the slit 70 and the hole 18 is not visible.

Internal element 300 is different from the inner element 3 (Supplement) the absence of ribs 105 and the addition of a partition 65 in the lower section of the exhaust nozzle 43. In addition, the inner element 300 has the Cup 101.

Internal element 300 includes a filter 400, located in the annular channel 69 between the middle along the flow of the plot 69U and far upstream of the section 69D. The filter 400 comprises openings 401, which have such dimensions that when using a large portion of oblong agglomerated particles retained on the near end on the downstream side of the filter. The filter prevents most of oblong particles from reaching the openings 128 and thereby helps to prevent the hole 128 from becoming partially or completely blocked oblong particles. In this regard, the reproducibility of the quality of the foam created using the cartridge 1', improved compared with the known in the prior art cartridges.

Holes 401 may have any suitable size and configuration. However, in order to achieve a suitable balance between maximizing the magnitude of elongated particles retained by the filter 400, and minimizing the violation of the fluid flow inside the cartridge, the openings 401 preferably have a maximum size near along the flow surface, which is not bol�e 1.6 mm. Holes 401 in the best case have a maximum size near along the flow surface, which is not more than 1.0 mm to optimize the balance between maximizing the magnitude of elongated particles retained by the filter 400, and minimizing the violation of the fluid flow inside the cartridge.

The maximum size of the hole 401 is defined as the linear distance between the two farthest apart points on the periphery of the hole near upstream of the filter surface.

The size of the holes 401 may be associated with the size of the hole 128 so that the area of the holes 401 is not more than ten times larger than the area of the hole 128 and the orifice has its maximum cross section. Alternatively, the size of the holes 401 may not be more than seven times larger than the area of the hole 128. Also alternatively, the size of the holes 401 may be no more than five times the area of the hole 128.

As indicated above, optional for filter 400 to hold all elongated particles at close on the downstream side of the filter. There are large agglomerates, which are more able to disrupt the operation of the cartridge. In this regard, it is preferable that the filter is kept longer oblong particles near upstream of the side.

Fig. 3 shows a perspective view alterna�active inner element 310. Inner member 310 is the same as the inner element 300 described above, except that it contains an alternative geometry eductor. Internal element 310 includes a filter 410 having openings 411, which have such dimensions that when using retain most of the oblong agglomerated particles at close on the downstream side of the filter.

Fig. 4 and 5 show views in perspective of further alternative inner element 320. Some of the symptoms of inner element 320 are the same as described above with reference to the internal element 3 in Fig. 1, with need same reference position used to denote the same features.

Internal element 320 contains the discharge spout 43 is surrounded by the outer tube 42, which is connected to the discharge spout 43 of the annular flange 47. Inner member 320 also includes skirt section 380, which is connected to the outer tube 42 of the skirt ribs 87. Annular channel 69 is defined between the inner wall of the skirt section 380 and the external wall of the external tube 42.

Skirt 380 contains a filter 420 having a plurality of elongated slits 421, located on the lower part of the skirt 380. Fig. 1 in the assembled cartridge lower part of the skirt 380 is in contact with the laminate 5 so that the lower cha�th holes 421, essentially, closed. Slit 421 provide the message on fluid between chamber 134 and the channel 69. Slit 421 have such dimensions that when using retain most of the oblong agglomerated particles in the chamber 134 near along the flow side of the filter 420.

The invention is described above by way of example, implemented in the cartridge is formed from, among other parts, the outer element and inner element. In particular, the hole 128 is described as limited areas of external and internal elements. However, it should be clear that the invention is also applicable to holes formed in a single component and not from the connection of the two components.

Described cartridge is suitable for any liquid product which forms an elongated agglomerates. For example, a concentrated chocolate enhances the flavor of the syrups or vitamin supplements.
