The technical field

The invention relates to a capsule for preparing and obtaining a drink in the device for preparing beverages, in particular, to the means of opening intended for the opening of the capsule to create an outlet for the beverage with improved parameters for the exit of fluid.

The level of technology

The prior art capsules containing roasted and ground coffee, through which hot water passes under the action of gravity forces. The capsule of this type is described in patent document GB 1397116. In this method, water is injected through the top of the cartridge and flows down through the ground coffee, the filter, and finally through the opening or hole, in the bottom part. The same approach is based more complex systems that use truncated-conical cartridges, such as, for example, described in patent document US 2002/0148356, or rectangular cartridges, such as, for example, described in patent document US 2002/0148357.

In one commercially successful capsule systems for extraction of the coffee beverage from the capsule airtight and waterproof capsule is placed in the extraction device, injection into the capsule hot water up until the internal pressure in the capsule reaches the value at which the closing membrane is srivatsa or breaks so in order of the capsule could leave liquid extract. Capsule designed for such extraction process described in document EP 0512468. The process described in document EP 0512470. This method allows to obtain a high quality coffee beverage type espresso. The capsule is filled with freshly ground coffee, which can be stored in the capsule for a few months, virtually no loss of flavor. The output of coffee comes with a small delay caused by the slow opening of the membrane under the influence of pressure generated after the start of water injection into the capsule. In the extraction of the coffee takes place under optimum pressure and temperature conditions. The formation of persistent and heavy cream or foam due to the high compression ratio, pressure relief and recovery gas specific method.

Meanwhile, similar to the capsule and the process are not optimal for infusion or brewing beverages such as tea or herbal tea.

Therefore, the market appeared capsules containing tea products, etc. Should be understood that the quality of the brewed tea drink largely depends on the quality of ingredients, tea leaf, i.e. the origin of the used tea (soil, drying, blending and the like), as well as storage conditions. For example, tea ingredients are usually susceptible to all the action of oxygen and light. Preferably used tea ingredients from leaf, chopped or cut into small pieces of tea. Meanwhile, to obtain from ingredients high-quality drink is important and welding conditions.

Another problem that should be avoided when preparing beverages from tea, taste is a cross contamination. Cross-flavour contamination occurs when the device is consistent with the brewing of two capsules, and taste the first capsule is transmitted to the stationary parts of the device, which ultimately can affect the taste of the second capsule, weld immediately after the first capsule. This may be true for certain types of tea, with a strong taste, such as tea from peppermint or other varieties strongly flavored tea.

In the patent document WO 2007/042414 A1 describes a device for preparing drinks and a special capsule that is designated to receive welding at relatively low pressure and, in particular, are suitable for the preparation of tea drinks. Therefore, the capsule includes a compartment that contains one or more ingredients to make the drink, the filter wall bounding at least one filtering side of the Department, as well as the drain wall which is located on the route after welding filter walls and which contains at least one drain hole or involves at least one piercing means or index-breakdown means, respectively, able to punch or to specify, respectively, at least one drain hole.

In addition, according to the invention offers the design of the capsule and special revealing element of a device for preparing drinks to simplify and improve the preparation of a tea drink or tea drink of herbs.

In particular, attempts to improve the output parameters of the beverage from the capsule, to avoid creating pressure in the flow of the beverage from the capsule.

The present invention also pursues other objectives, in particular the solution of other problems, as will become clear from the rest of the present description.

It should be understood that in this application the term "tea" includes all types of leaf tea, such as green tea, black tea, white tea, masala tea, flavoured tea and herbal or fruit tea. In addition, the term "leaf tea" or "sheet ingredient" refers to brew tea or other ingredients, regardless of the form, such as whole, sliced or chopped leaves, small sheet fragments, powder or dust.

Above the aforementioned objectives, in particular, are achieved according to the first object of the present invention using a system consisting of a device for preparing drinks and capsule for preparing a beverage contained in the compartment capsule of food substances by injecting liquid into the capsule; a device for preparing drinks includes means for opening intended for interaction with the wall forming the outlet surface of the capsule, and means opening contain revealing element of the hook shape that is designed for cutting and removing at least part of the lid, hermetically attached to the discharge surface of the capsule.

Accordingly, a means of opening an incision in the lid, hermetically attached to the discharge surface of the capsule to create an outlet for the beverage exiting the capsule.

Opening element is a hook element, which is configured to reject at least part of the cover in the direction of the upper surface of the hook element.

Accordingly, creates a wide opening, preventing the increase of pressure inside the capsule during the release of the beverage from the capsule.

Accordingly, improved output options beverage from the capsule. However, none of the parts of the cover does not shield created prom is twistie for a drink, that eliminates the pulsation of the beverage exiting the capsule. Thus, no formation of bubbles and provides an attractive appearance of the tea drink.

Preferably the means of opening contain essentially longitudinal cutting edge.

Device for preparing drinks may also contain at least one locking element is connected to a closing mechanism for selectively locking the said capsules in the receiving chamber of the device. In addition, the device may include an external or internal feeder fluid and a pump connected with a source of fluid supply, intended for the supply of liquid in the receiving chamber.

According to a preferred variant of the invention, the means of opening configured to move relative to the capsule. So the opening is preferably connected to at least one locking element, and accordingly, during the closing movement of the closing mechanism, which is connected to the locking element, means opening begin to interact with the wall forming the outlet surface of the capsule.

Hook element means opening preferably curved or inclined relative to a vertical base means opening. It's about legcay deviation of the cover in the direction of the upper surface of the hook element.

According to a preferred variant implementation of the hook element has a longitudinal cutting edge. In such an edge can be made of the Central recess. Cutting element walls of the capsules are preferably butt hinges in the lid. Cutting element preferably has a tapered tip which can slide in the recess formed in the longitudinal cutting edge of the hook element.

Cutting element may have any other geometric shape that provides interaction with essentially the longitudinal cutting edge of the hook element.

In addition, the means of opening preferably contain made in one piece guides tools designed to redirect beverage from the capsule into the container. According to a preferred variant implementation guides tools contain cumulative element located at the base of the means of dissection. Therefore, the cumulative element can be banneroobmena recess in order to collect the drink that goes through the hole made in the lid.

Hook opening element is preferably with the possibility of full membership in the cover, cut so that the guides means rested butt into the exhaust hole created in the lid So created the outlet is preferably located so to strike the item is not prevented drink created through the outlet. Accordingly, a means of opening not reduce the hole created in the exhaust cover, which increases the flow rate of the beverage from the capsule.

In addition, guide means preferably contain essentially vertical rib, protruding from the base means opening. Preferably the vertical rib protrudes from storage element. Accordingly, the beverage coming from the outlet of the capsule, is collected in a storage element and is sent from the base means opening vertically down towards the tank. Thus, the drink goes vertical edge toward the container. In particular, any remaining droplets travel along the edges due to the strength of the adhesive interaction between the droplets and the surface of the guide means. Guiding edge may also be installed at a slight vertical angle.

The lower end part of the guide means is preferably formed by the ends of the vertical ribs. So goes the drink flows down the edge down and, eventually, under the influence of gravity is separated from him. Respectively for directing fluid into the tank does not require a tube or tubular means. Thus the m essentially, there is no cross contamination when using different capsules inside the device for preparing drinks, and consequently, brew drink can properly and hygienically to act in the capacity of, for example, set the bottom of a mug or Cup.

The second object of the present invention is a capsule for drink preparation device for preparing beverages containing:

- compartment for ingredients,

- the cover is hermetically attached to the discharge surface of the capsule, the wall includes a cutting element, the butt resting on the lid and configured to interact with the special means of the opening device for the beverage so that when opening the device at least part of the cover into fragments between the cutting element and means opening.

Thus, the cutting element is configured to communicate with a longitudinal cutting edge special funds opening.

According to a preferred variant implementation of the cover is a single layer or a multilayer. The cover preferably contains at least and Jomini.

The wall is made of at least one pre-formed channel, located on the discharge surface of the capsule and is made with the possibility of sending the fluid from the at least one drain hole in at least one recess made with the possibility of the occurrence in it of special funds opening device for preparing drinks.

Thus, when fluid is injected into the capsule, for example, by perforation of the inlet surface, it begins to interact with the ingredients inside the compartment. With the continuous injection of fluid into the capsule to its level inside the capsule rises and accordingly the drink, resulting from the interaction of the fluid with the ingredients of the drink inside compartment ingredients out of the compartment, at least through one hole in the wall of the capsule.

Preferably, in the intermediate gap between the final surface and the lid is hermetically attached to the exhaust surface is at least one pre-formed channel. Therefore, to prevent adhesion of the cover to the wall forming the outlet surface of the capsule, the gas under pressure preferably is retained by the lid, hermetically attached to the rigid wall forming the outlet for Ernest capsules. The adhesion between the wall and cover effectively prevented. Accordingly, simplified cap opening special means of opening, which is preferably cut at least part of the cover is attached to the wall.

Due to the gas pressure and swelling of the lid wall may be located on the outermost side of the hole capsules, not allowing the lid to stick to it and providing maximum protection ingredients found in the compartment of the capsule. This swelling also improves the aesthetic appearance of the capsules.

At least one pre-shaped channel is preferably formed in the rigid wall of the capsule. Therefore, the beverage coming out of the Bay of ingredients, at least one hole made in the final surface, preferably pumped through the pre-formed channels under the action of gravity.

The implementation of the invention

First and foremost is the General method of preparation according to the present invention with reference to figures 1 and 2, as well as the capsule according to before actualname variant embodiment of the invention.

Features capsule system 30 consisting of a capsule 1 and the device 10 for making beverages. In order to simplify the device for preparing drinks depicted only schematically and in fact may have additional specifications, typically known to specialists in this field of technology.

Capsule 1 has a compartment 2 for ingredients, which are the ingredients to prepare drinks, such as tea leaves, etc. Compartment for limited ingredients Cup-shaped housing 32 and the wall 4. Thus, the capsule 1 has an inlet surface 6A formed part of the Cup-shaped housing 32. In addition, the capsule has a discharge surface 6b formed by the wall 4 and the cover 11, the cover wall 4.

Preferably the filter wall 33 fixed to the district internal ledge 34 of the housing 32, closing, so the ingredients for the beverage inside the Cup-shaped housing. Compartment for ingredients is preferably gas - and light-tight.

The shape of the body 32 in cross-section, which, in turn, determines the overall contour of the filter walls 33 may be different, for example circular, ellipsoidal, square, rectangular or polygonal. The size of the compartment of the ingredients is selected so that it is a VM which forbade the dose of sheet ingredients for the beverage weight of usually from 1 to 10 g, preferably from 2 to 5, the Dose of sheet ingredients may depend on the final volume of brewed beverage. The usual dose for making one Cup of tea can be about 2 g, whereas the usual dose for the preparation of the teapot can be from 8 to 10, As shown in figure 1, the capsule is relatively brewing device so that the wall 4 and the filter wall 33 were essentially vertically and, essentially, from the bottom of the cavity. For this, the capsule preferably is installed in the device 10 for making beverages "vertically". Thus, the inlet and outlet surfaces 6A, 6b Cup-shaped housing 32 is preferably located essentially vertically.

In the final surface 6b in the wall 4 is preferably at least one drain hole 22. At least one drain hole 22 communicates via a fluid from compartment 2 for ingredients.

The capsule 1 is closed by a cover 11, which hermetically closes the cavity of the capsule 1 and, respectively, the compartment 2 with the ingredients and the wall 4. Cover 11 is preferably attached to the outer part of the district of rim 21 of the housing 32, such as a flange, as shown in figure 5 and 6. Therefore, the outlet wall of the capsule 1 is formed a channel 23 that is designed to down direction of the fluid from the about at least one drain hole 22. The second part 21b of the rim preferably essentially opposite to the first side 21A of the bezel, next to which is a hole made in the lid. Accordingly, the liquid coming out of the compartment with the ingredients through the opening 22, is sent down, essentially parallel to the exhaust side 6b of the capsule 1.

Cover 11 and the housing 32 can be made of materials having barrier properties to oxygen, in order to, essentially, due to the lack of oxygen in the cavity of the freshness of the ingredients for the beverage could persist for a long period of time. Hermetically closing wall is preferably flexible and punched a tightly closing lid, such as a single-layer or multi-layer cover, usually consisting of layers of polyethylene terephthalate (PET)/aluminium/polypropylene (PP), polyethylene (PE)/copolymer of ethylene vinyl alcohol (was found)/polypropylene (PP), polyethylene terephthalate (PET)/metal layer/polypropylene (PP), aluminum/polypropylene (PP), paper.

The cavity may contain a purge gas, for example, N2N2O or CO2.

The housing can be produced industrially at low cost due to thermoforming plastic or deep drawing of aluminum.

The brewing device 10 for preparing drinks preference is sustained fashion contains two locking element 8, 9, made with the possibility of locking capsule 1 within the reception chamber 5 of the device, in which the capsule may be placed by the user. As already noted, the locking elements 8, 9 is arranged to hold the capsule in a vertical position. Therefore, preferably one of the locking elements 8, 9 is connected to the closing mechanism (not shown) to selectively move the locking elements 8, 9 relative to each other. Thus, through the use of a closing mechanism, at least one locking element connected to the closing mechanism is moved relative to the other locking element. Accordingly, the locking elements 8, 9 can be moved from the first position of the insertion of the capsule, as shown in figure 1, in the locking position of the capsule, as shown in figure 2.

Such locking elements 8, 9 can be mechanical clamps or any other appropriate mechanical locking means capable of close and trip around the capsule and securely hold it in place. High closing effort is not required, because the pressure of the fluid in the capsule remains relatively small and, preferably, as close as possible to atmospheric pressure. Also, because the capsule can withstand low pressure p and brewing, the capsule does not need to be locked completely, and only waterproof be held in place during brewing. This contributes to simplification of the structure of the device and reduces the cost of the device.

Device for preparing drinks consists of an external or internal source 11 of the liquid supply, such as a water tank, a water pump 12, the heating means 37, such as a thermostat, and a discharge line 35 for supplying hot water passing through the locking element 9. Device for preparing drinks may also contain a controller and panel user interface (not shown) to control the cycles of the preparation of drinks, known from the prior art.

The check valve 36 may be installed with the inlet side of the injection into the capsule element 39 (for example, needles (needles) or blades (blades) and the inlet for water).

Tea also contains tools 3 opening intended for cutting of the cover 11 through the interaction with the wall 4 of the capsule. Means 3 opening preferably connected to one of the locking elements 8. Thus, the means 3 opening configured to cover opening 11 of the capsule through the creation of outlet openings 38. Preferably the means 3 opening made with the possibility of cutting of the cover 11 for shatsampatti with special cutting element 27 (see 4) wall 4.

The opening of the cover 11 and, accordingly, the engagement means 3 opening with the wall 4 preferably occurs when the locking elements 8, 9 of the device 10 are transferred from the position of insertion of the capsule shown in figure 1, in the locking position of the capsule shown in figure 2. Moving the locking elements 8, 9 relative to each other can be linear or rotary movement or by a combination of linear and rotary motion.

During the operation of the brewing process, shown in figure 2, the wall 4 serves as the drain wall, and the hole 22 serves as a drain hole. Thus, the capsule preferably is located in the unit so that the drain hole 22 were above the median horizontal plane P capsule.

Also, as can be seen in figure 2, the filtering wall 33 and the wall 4 is located at a small distance from each other sufficient to create an intermediate gap "s", the speaker, without theoretical confirmation, as a kind of "siphon"conducive to bringing up more dense part of the drink, which is mainly collected in the bottom part of the cavity. The intermediate size of the gap may be from 0.1 to 8 mm, preferably from about 0.5 to 3 mm.

As shown in figure 2, the method according to the invention is carried out following the way. The capsule is inserted in the device for preparing drinks, after which the locking elements 8, 9 are closed around the capsule, aligning it so that the inlet and outlet surfaces 6A, 6b located essentially vertically. Then the funds 3 create opening the discharge opening 38 in the cover 11, which is tightly attached to the rim 21 of the capsule. On the opposite side of the capsule element 39 of the injection fluid enters the compartment 2 with the ingredients of the capsule. Hot water is injected into the capsule under a relatively low pressure, preferably less than 0.2 bar. The capsule is gradually filled with hot water, and the ingredients for the beverage, which is in the cavity, are immersed in water. The brewed beverage is filtered through the filter wall 33. Thicker portion 40 of the drink can settle to the bottom of the cavity; this part is also filtered through the filter wall 33, because it is near this part. A thick drink is removed through an intermediate gap "s" due to a pressure difference between the bottom of the gap and the upper part of the above-mentioned gap, acting as the "siphon". The rest of the drink is filtered by passing through the filter wall 33 at different vertical levels up to the upper level of the fluid in the cavity, and displays the Xia through the drain hole 22.

It should be noted that the drain hole 22 should preferably be above the median total height of the compartment with the ingredients and preferably higher than 4/5 of its total height, which provides a more complete immersion of the ingredients for a drink and a slower withdrawal of beverage from the Bay, which contributes to improvement of the process of infusion.

Under the "total height" compartment refers to the total distance from the extreme lower point of the compartment to its extreme upper point after installation ready for the brewing process of the capsule in the device for preparing drinks. According to one of the possible options for the height of the filter walls 33, essentially, can be equal to the total height of the compartment.

The outlet 38 that is created in the cover 11, preferably located below the openings 22. Therefore, the liquid coming through the drain hole 22, is directed essentially parallel to the discharge surface 6b of the capsule before it reaches the outlet 38 of the capsule. To drink between the hole 22 and the outlet 38 into the exhaust surface 6b of the capsule is preferably at least one guide channel 23 (see figure 3).

After leaving the capsule 1 drink preferably directed guide means 13 (see figures 3A, 3b) means scry the Oia device for preparing drinks toward the container 20, such as cups or mugs.

Next, with reference to figa and 3b will be described the means of opening according to the preferred implementation of the present invention, and figa means of opening shown in perspective, and on fig.3b means of opening shown in cross-section, side view.

Means 3 opening preferably made of plastic, for example, by casting under pressure. As shown in figa, means 3 opening preferably contain the connecting element 43, such as studs, designed to provide connection means 3 opening and locking element 8 of the device 10 (see figure 5).

Means 3 autopsy contain opening member 7 protruding from essentially vertically positioned base means 12 3 opening. Opening element 7 preferably is a hook element which is inclined at an angle α to the base means 12 3 opening. The angle α preferably ranges from 40º to 65º.

Hook element 7 has an inclined wall 7a and two side walls 7C, located around bunkerovochnogo compartment 14. Longitudinal edge of the inclined wall 7a acts as the cutting edge 8 of the hook element 7. Therefore, the longitudinal edge 8 is preferably located essentially horizontally within the device 10. Alternatively,the longitudinal cutting edge 8 may be made of the Central recess 8A, preventing the beating of opening element 7 on the edge 27A (see Fig 4) cutting element. The length of the longitudinal edge 8 is preferably from 1 to 25 mm

Accordingly, when the engagement of the hook element 7 with the cover 11 of the capsule it is a large hole.

After opening element 7 cuts the cover 11 (see figure 2), the cover part 11 is deflected by the upper surface 7b hook element 7. Therefore, the upper surface 7b may be curved or smooth ledges, as shown in fig.3b.

The base means 3 opening preferably located between the two vertically-arranged side walls 12A, forming, thus, open channel 13 for the fluid that is designed to direct the liquid to buckeroomama cumulative element 14 and then into the container 20 that is installed from the bottom of funds 3 opening (see figure 2).

In addition, from the site of base 12, in particular from the open channel 13, is essentially vertically located rib 15. Thus, the upper portion 15A of the ribs 15 are preferably protrudes from the center bunkerovochnogo cumulative element 14. Thus, the protruding rib 15 is held within the guide means 13 in the direction of its lower part 15b, these lower part 15b may act as a discontinuous chrome and guide means 13. Accordingly, a drink, going out through the outlet 38 of the capsule 1, going in-depth cumulative element 14, and then through the guide means 13 is directed toward the container 20. Therefore, any remaining drops of drink under the force of gravity is directed toward the bottom of the ribs 15, the tip of which droplets break so that the drink is, essentially, did not stick/not remained within the guide means. It actually helps to reduce cross contamination.

In addition, due to the fact that the guides means 13 have the form of a channel or groove, you can refuse the use of conventional guide means, such as a tube, which prevents the accumulation of residual liquid within the guide means.

Figure 4 shows the wall 4 according to a preferred variant implementation of the present invention, which is preferably connected to the housing 32 of the capsule. The wall 4 is preferably made of plastic by molding under pressure. As shown in figure 4, the wall is made of pre-formed channel 23 located around the circumference of the wall 4. Due to this, the pre-formed channel 23 communicates via a fluid with at least one aperture 22, which communicates via a fluid from compartment 2 to ingredien is s (see figure 1 and 2). Preferably, as shown in figure 4, in the upper part of the wall 4 made two holes 22.

As shown by the arrows A, the pre-formed channel 23 is made with the possibility of sending a drink that goes through the hole 22 in the upper wall of the capsule toward the bottom of the wall. In the pre-formed channel 23 preferably has no sharp corners or edges so that the liquid can be smoothly guided through the opening 22 toward the bottom.

To ensure the smooth passage of the drink, routed through an intermediate gap between the cover 11 and the wall 4, i.e. through the previously formed channel 23, the size of the intermediate gap "t" is preferably from 1 to 10 mm (see figure 2).

In the lower part 21b of the wall 4 has a recess 26 which has a capability of entering into it hook opening element 7 tools 3 opening during the engagement means 3 opening with 1 capsule.

The recess 26 is communicated in fluid with the pre-formed channel 23.

In addition, inside the recess 26 is cutting element 27 made interoperable with a longitudinal cutting edge 8 of the opening element 7. Cutting element 27 is retained by the cover 11 when the opening element (7) in contact with him, which increased the AET tension of the cover 11 and simplifies its cutting. Thus, the cutting element 27 preferably is wedge-shaped with a longitudinal cutting edge, which preferably is parallel to the longitudinal cutting edge 8 of the opening element 7 during the interaction means 3 opening with 1 capsule.

In addition, in the wall of the capsule can be made more holes, in particular holes 41, which are preferably located in the Central part of the wall 4. The said recesses or holes 41 are designed to ensure interoperability between wall 4 and special recognition means (not shown) of the device is able to determine the type of ingredients that are in the capsule 1. Thus, the nature of the ingredients inside the capsule can be detected using special pins available to the locking element 8 that allows you to determine the type of a capsule for preparation of a drink. Accordingly, the parameters of the brewing of a capsule in the device can be changed, for example as described in patent document EP 1950150.

It should be noted that the holes 22 are preferably made in advance and they do not need to be done by means of dissection. Meanwhile, the holes 22 may be mounted filter elements, which prevents the release of tea leaves from the compartment 2 with the ingredients.

Figure 5 show the us in the future interacting capsule and means of opening according to a preferred variant embodiment of the invention.

As shown, the means 3 opening connected with the locking element 8 by means of connecting rods 43. It should be noted that the locking elements 8 and 9 can linearly move relative to each other from the first position of the insertion of the capsule (figure 1) in the second locking position of the capsule (figure 2). Meanwhile, the first and second locking elements 8, 9 can also be moved relative to each other through a combination of linear and rotary movements.

As it approaches the locking element 8 to the exhaust surface 6b of the capsule formed by a wall 4, hook opening element 7 breaks the cover 11, which is tightly attached to the wall 4 with an outlet surface 6b. It should be noted that the cover 11 figure 5 is not shown. Thus, the gas preferably is retained by the cover 11 so that the surface of the cover was pulled from the outlet surface of the capsule, which facilitates the opening of the capsule by cutting the cover 11 by means revealing item 7.

The opening of the cover 11, in particular, at the expense of tearing it between the cutting element 27, butt resting on the inner surface of the cover 11, and a longitudinal cutting edge 8 of the opening element 7. Thus, the longitudinal cut edge 27A preferably communicates with a longitudinal cutting edge 8 and/or the recess 8A, u is contained preferably in the Central part of the longitudinal cutting edges 8, so that between them there was a tearing of the cover 11. Thus, the cover part 11 is deflected inwards in the direction of the recesses 26 of the wall 4 of the capsule, which houses the hook element 7.

The locking element 8 may be equipped with means 42 identification that includes recesses 42A, which include studs (not shown) to identify the inserted capsule 1 through the interaction with holes or recesses 41, made in the wall 4 of the capsule. Thus, the cover 11, which is tightly attached to the wall 4 can get in its Central part for the implementation of the identification.

Figure 6 shows in an enlarged view in perspective capsule and means of opening according to a variant embodiment of the invention shown in figure 5.

As can be seen in Fig.6, hook opening element 7 preferably fully inserted into the recess 26 of the wall 4. It should be noted that the cover 11 figure 6 is not shown.

Accordingly, due to the inclined surface 7a hook element 7 a of the cover 11 is fully deflected in the direction of the center of the capsule 1. Due to this, you create a vent opening 38 (see figure 2) is of sufficient size through which liquid can leave the capsule without increasing the pressure in the capsule. In particular, if the difference is torn cover 11 none of h is the capacity of the cover is not blocking the exhaust port 38. Moreover, since the hook element 7 is completely contained in a special recess 26 in the wall 4, the means 3 opening also not obscure generated discharge outlet 38.

As shown by the arrows A, the drink comes out through the holes 22 and is directed through the pre-formed channel 23 in the tipping part 21 of the capsule to the outlet 38. Thus, the drink is collected in buckeroomama cumulative recess 14 of the hook element 7 and is directed guide means 13 toward the container 20. Thus, since banneroobmennoy cumulative recess formed in the base means 12 3 opening, and also due to the fact that the drink is suitable for hook element 7 from the bottom, means 3 opening and, in particular, the opening element 7 does not obstruct created the outlet 38, which effectively prevents an increase in pressure inside the capsule during brewing. Accordingly, significantly improve the output of the beverage from the capsule.

Although the present invention has been described with reference to preferred variants of its implementation, it can be done numerous modifications and changes experts having ordinary knowledge in the art, without departing from the scope of the present invention that the op is edelen in the accompanying claims.
