The invention relates to a capsule portions extracted with water substance in the form of particles for the preparation of the drink, according to the restrictive part of claim 1 of the claims.

Such capsules are known in various embodiments and, in particular, well-known capsules for placing ground coffee with the purpose of preparation of espresso coffee. The principal benefit of these capsules is that they are gas-tight and support contained in the coffee powder fresh for a long time. For making contained in the capsule coffee powder is still used mainly semi-coffee "espresso", in which the capsule is inserted into capsulerebel lid down. Then capsulerebel manually fix on the coffee maker, and coffee in the area of the fixing holder has a teapot, and a rod which is provided with radial outlet openings for the flow of brewing water and which pierces the capsule bottom pinned capsulotomies on the coffee maker. In turn, capsulerebel provided at the bottom of many hills, located on the drain grate. These elevation penetrate through the lid of the capsule and break it as soon as the brewing water enters settersten and hydraulic excess pressure will squeeze the capsule to those in which swystem. In the subsequent process of brewing the brewing water flows through the brewing rod into the capsule, so that it can be washed with excess pressure in the capsule coffee powder to flow through the holes in the lid. Freshly brewed coffee can flow through the drain grate and pour through the editions on the underside of saturates. Coffee with a similar device for the extraction of contained in the capsule coffee powder is known for example from EP 0512470.

The disadvantage is provided with radial holes brewing rod is that important for the production of tea water tea section of the rod relatively quickly clogged due to clogging. As reasons for this might include, for example, caffeol, the coffee particles and the lime in the brewing water. As clogging of brewing rod is deteriorating, however, and the quality of the brewed coffee. From the hydraulic point of view, another problem with this tea rods is that inside the capsule there dead volume, so that a portion of coffee powder is extracted water or tea extracts only slightly.

Another drawback named brewing rod is that he leaves in the capsule relatively large punched a hole through which, in particular after extracting tea with Erina, may fall extracted coffee powder, which, eventually, can clog the coffee maker. This problem occurs in particular when the capsule is placed in the coffee maker so that punched the back of the capsule passes vertically downwards, so that the extracted coffee powder after extract brewing rod is under the influence of gravity to fall down from the capsule.

From EP 0521188 know other device for the extraction of contained in the capsule coffee powder. In addition to brewing rod for feeding brewing water into the capsule in one preferred exemplary embodiment of this device is provided by the water distribution grid, containing at its lower side protruding elements for punching the upper side of the capsule. Tea water is distributed through a distribution grid on the upper side of the capsule and can penetrate into the capsule through the gap between the protruding elements and the lid of the capsule.

Further, from EP 0512468 known portion packaging according to the generic definition, also suitable for ground coffee. Consisting of a combined material of portion packaging has no filter and place of weakened strength, and the bottom or lid are designed to break under pressure extractional fluid on the ale extraction.

The principal disadvantage of the known portions of the packaging is that the machine requires large expenditures that are contained in portion packs coffee powder more evenly tea washed with water and completely extracted. In addition, portions of the packaging is torn only under the action of pressure extractional fluid at the beginning of the extraction, there is a risk that the capsule will break (perforated) in all the right places, making coffee powder again extracted only is not enough. Another disadvantage to be seen in the fact that the perforations partially undesirable great, and it is not conducive to flowing tea water, because tea water meets only a small resistance and, in addition, there is a danger that through too large hole portions of the packaging will be able to sleep coffee powder, which will clog the coffee maker.

In EP 1101430 system disclosed drink-filter capsule, equipped with a stepped portion capsule. The capsule has several ledges serving to maintain the filter element and the porous membrane. Between the filtering element and the membrane placed powder drink. Between the cover and filter element, and between the bottom and the membrane remains ol Mejuto, designed for side entry inlet and drain pipes.

Finally from US 2778739 known integral portion capsule. It consists of a Cup-shaped housing, in which is placed the insert, made on the underside of the metal. The upper side is closed with welded lid. Named the insert has one round external and one adjacent to the inner side of the Central recess. The Central recess deeper than the external, and can take a punch, with which pierce the bottom of the capsule. Punch serves simultaneously for feeding brewing water. The insert has a multitude of holes through which the brewing water can flow into the capsule. For punching of the cap of the capsule is provided by the thorns.

Proceeding from the aforementioned prior art, the invention consists in the improvement capsules, specified in the restrictive part of claim 1 of the claims, so that it contains the extracted substance is evenly washed with water and as best as possible was extracted.

This task portion capsule extracted with water substance (CU) in the form of particles for the preparation of a beverage containing installed between the bottom of the capsule and substance (CU) and/or between the lid of the capsule and substance (CU), made with lots of holes structural element according to image ateneu is solved by that it has channels formed embossed reliefs, for water distribution or collection of drink, respectively.

Embossed reliefs structural element can be directed to the bottom of the capsule, so that between the structural element and the bottom of the capsule remain available space, forming channels for the liquid.

Embossed reliefs structural element can be directed to the lid of the capsule, so that between the structural element and the lid of the capsule remain available space, forming channels for the liquid.

Openings for the flow of fluid are located in the channels for the liquid.

Embossed reliefs are distributed so that the structural element rests flatwise on the bottom or the lid of the capsule, respectively.

Channels for the fluid going from the symmetry axis, are radially outward and around the symmetry axis.

Structural element as a dispenser for water and/or collection of the cooked juice, respectively, or is made with the possibility of entering through the cap and the capsule bottom, respectively, of one or more punches without piercing the distributor and collector, respectively.

Collection and/or distributor has at least one, facing the inside of the capsule recess, in which, after the por is byvania bottom and respectively cover includes a punch or punches.

The collector or distributor may be located inside the capsule at a distance from the bottom or from the lid of the capsule, respectively.

The recess is located in the center of the collector and distributor, respectively.

The recess is made conical, spherical, or in the form of a parallelepiped.

The average diameter of the individual holes is less than the statistical average value of the diameter of individual particles of the extracted substances.

The bottom and/or cover provided with a place of weakened strength to enter the punch or punches.

Between the bottom of the capsule and extractable substance (CU) and between the lid of the capsule and extractable substance (KR) are the distributor and collector, respectively, and the collector and the distributor is supplied with each recess, in which, after piercing the bottom and the cover, respectively, at least one punch can enter without piercing the distributor and the collector.

Thanks to the provided at least one authority mentioned kind can on the corresponding side portions of the capsule, regardless of the number and size of the punched holes (holes) to ensure uniform distribution of water, introduced for the extraction of a substance.

Mainly on both sides of the matter, i.e. between the bottom of the capsule and matter and between the lid of the capsule and substance are respectively dispenser for water and collection for drink. In addition to the uniform distribution of water this has the advantage that the substance is enclosed between these two elements without the possibility of rash through the punched holes, even if they are relatively large.

The placement of the element between the cap of the capsule and the substance has the additional advantage that after the placement of the distributor of the capsules can not sleep, a particle of matter that, for example, has a positive effect on the welding of the lid of the capsule due to the fact that the edge of the capsule is less "contaminated" by the particles.

In one preferred exemplary embodiment provides that the corresponding element is equipped with embossed reliefs, directed towards the bottom and the lid of the capsule, so that between the respective element and the bottom or lid of the capsule remain available space, forming channels for the liquid. This implementation is suitable, in particular, to combine with the distributor or collector, which is made with the possibility of entering one or more of the punches through the bottom or the lid of the capsule, not punching while the distributor or collector. We designed the capsule brewing water can be introduced from the outside into the capsule through the punched hole. Due to the fact that the corresponding element rests flatwise on the bottom or the lid of the capsule, as this is stated in the preferred exemplary embodiment, guaranteed to channels for fluid between the cap of the capsule and the valve is maintained even when the current on the outside of the capsule pressure.

Below is an example of carrying out the invention is explained in more detail using the drawings. These drawings represent:

- figure 1: a separate part of the capsules in disassembled form;

- figure 2: longitudinal section of a first exemplary embodiment capsules;

- figure 3: longitudinal section of a second example of execution capsules;

- figure 4: longitudinal section of a third exemplary embodiment capsules;

- figure 5: longitudinal section of a fourth exemplary embodiment capsules;

- 6: longitudinal section of a fifth exemplary embodiment capsules;

- 7: cross-section of capsules on line H-H figure 6.

Figure 1 is a disassembled detail explains the basic design capsules. Although such portions of the capsules can be placed, in principle, a variety of extractable water substance for the preparation of beverages, below come from the portion of capsules filled with coffee powder for the preparation of regular coffee or espresso. When looking up from the bottom portion of the capsule comprises a Cup 1, bottom collector 2, the top of the distributor 3 and the cover 4. Located between the collector 2 and the distribution is ielem 3 in 1 coffee Cup powder here is not visible. As the Cup 1 and the cover 4 is made of gas-tight multi-layer composite film. The collector 2 and the valve 3 is made essentially disc shaped and manufactured mainly by a deep hood.

Slightly conically expanding up the Cup 1 is provided in the upper part of the around the ledge 5 which forms on the inner side of the circular shoulder 5A serving to support the top of the distributor 3. On the upper side of the Cup has a frame edge 6, which is fixed to the cover 4. The fixing cap 4 can occur, for example, adhesive or welding. Collection 2 has many embossed reliefs 9 and the shape of a circular segment, which elevations are for the lower side of the collector 2. When the collector 2 is placed in the Cup 1, embossed reliefs 9 rest on the bottom of the Cup 1, so that between the embossed reliefs 9 and the bottom of the Cup formed by the channels 17 for the liquid, which, going from the symmetry axis, are radially outward and around the symmetry axis. Outside is embossed reliefs 9 in the area of the channels 17 for the liquid collector 2 is provided with many holes 8. In the center of the collector 2 is Central, inward capsules recess 10, is made conical. The flat middle part of the collection 2 passes at a radius of 11 in the convex region 12. This implementation prevents distortion of the collection 2 when placing into the Cup 1.

Top dispenser 3 mainly made from mirror-symmetrically relative to the bottom of the collector 2. The dispenser 3 also has many embossed reliefs 13 in the form of a circular segment, which in the form of elevations protrude from the top side of the distributor 3. Due to these embossed reliefs 13 on the upper side of the distributor 3 is formed channels 18 for the liquid, which, going from the symmetry axis, are radially outward and around the symmetry axis. Outside is embossed reliefs 13 in the area of the channels 18 for fluid, a plurality of holes 14. In the center of the distributor 3 is a Central, inward capsules recess 15, is made conical. On the outer side of the valve 3 provided around the edge 19, which rises relative to the channels 18 for the liquid and the upper side of which largely coincides with the top embossed reliefs 13.

When installing the top of the distributor 3 he leans downwards knob 16 on the envelope shoulder 5A of the ledge 5 of the Cup 1. When serving tea water for brewing coffee top dispenser 3 acts as a filter and dispenser for water, whereas the lower collection 2 also acts as a filter and collection for brewed coffee.

Figure 2 is a longitudinal section of the finished batch the capsule with her coffee powder CU. Coffee powder CU enclosed between the bottom of the collector 2 and the top of the dispenser 3. As can be seen, due to resting on the bottom 7 of the Cup 1 is embossed reliefs 9 collector 2 is formed channels 17 for the liquid. Also due to the embossed reliefs 13 in the valve 3 between the valve 3 and the cover 4 are formed channels 18 for the liquid.

For opening the capsules above and below the cover 4 and the bottom punch 7 by bolts 20, 21. Punches 20, 21 is injected into the area of the respective recesses 10, 15 through the cover 4 and the bottom 7 so that neither the upper dispenser 3 or lower collection 2 not punched by a punch 20, 21. The corresponding punch, by contrast, is included in the corresponding groove 10, 15. Tea water for brewing is contained in a capsule coffee powder serves mainly outside through the punched hole, as described, for example, in EP 01810498. However, there is no need to send brewed coffee to the Central punched hole, and it is only important that the brewed coffee through the collector 2 are able to flow more freely to the punched hole or holes to flow out of the capsule. In this case, should proceed from the fact that the brewing water is fed through the capsule from the top down. However, it is possible to provide a flow of brewing water through the capsule in the opposite direction, i.e. from the bottom up, as this designation is prohibited by the double arrow 22. Due to the channels 18 for the liquid supplied to the brewing water is evenly distributed over the whole cross section of the capsule. Through holes 14 in the upper dispenser 3 tea water gets inside the capsule, where it washes the coffee powder CU. Through the holes 8 in the bottom collection 2 brewed coffee flows on the lower side of the collector 2 and flows through educated on the bottom 7 of the Cup 1 channels 17 for the liquid to performed by the punch 20 Central punched hole, whence it flows out of the capsule and proceed by other means (not shown). Due to implemented in a similar way valve 3 and collector 2 is guaranteed that in the capsule particles drink uniformly tea washed with water and results in an even extraction of all coffee powder. In case, if the brewing water flowing through the capsule from the bottom up, the function of the distributor 3 and the collector 2 have changed places, resulting in lower element acted as a distributor, and the upper as a collection. In this sense, the terms "distributor" and "collection" in no case should not be understood as limiting. Embossed reliefs 9, 13 in any case distributed in such a way that the corresponding structural element 2,3 rests flatwise on the bottom 7 or the cover 4 capsules. It is preferable, in particular, when the tea water as in this case, served in a capsule from the outside through the punched hole. Due to this bearing flatwise guaranteed by the fact that the free spaces 17A, 18a between the lid 4 of the capsule and the valve 3, which form the channels 17, 18 for liquid, will also be maintained at a pressure acting on the capsule from the outside. If necessary, inside the capsule can be provided by vertical partitions, promoting uniform washing of the coffee powder and/or stable design of the capsule.

The diameter is made in the dispenser 3 and collector 2 holes 8, 14 mostly smaller than the statistical diameter of individual particles (coffee beans) for the preparation of the drink, mostly less than x-σwhere x should understand the arithmetic mean value of the diameter, and under σ - standard deviation. This guaranteed that almost none of the particle will not work or will not be washed out of the capsule, namely regardless of the size of the punched hole.

Figure 3 shows a longitudinal section of a second example of execution capsules, not completely filled with coffee powder CU. The lower valve 24 through the auxiliary frame 25 is separated from the bottom 7 of the capsule so that the coffee powder CU completely fills the space between the lower valve 24 and the top of the collector 26. This handicapped persons is painted to coffee powder CU will be placed in the capsule obliquely, which would result in uneven distribution of the brewing water in the capsule and the emergence of similarity hydraulic short circuit, causing the coffee powder CU was extracted would be uneven. Brewing water should in this example, the run-serve capsule from the bottom part 7, because the lower valve 24 cannot perceive high hydraulic compressive forces acting in the direction of the bottom 7 of the capsule.

Figure 4 shows a longitudinal section of a third example of executing portions of the capsule, and the capsule and here is filled with powdered drink not completely. In this example, the upper valve 29 through the frame 30 resting on the shoulder 5A and the cover 4, is separated from the lid 4 capsules so that the coffee powder CU here and completely fills the space between the upper valve 29 and the lower collector 28. Tea water in this example of execution is served in a capsule side cover 4.

Figure 5 shows performed analogously to example 4 capsule whose upper collector 31 by frame 32 is separated from the lid 4 capsules so that the coffee powder CU completely fills the space between the lower valve 34 and the top of the collector 31. However, the frame 32 is made in this case, strong in compression for MF is t, it is fitted with a ring-shaped inner part 33 and vertical edges, so that the brewing water can be fed into the capsule from the bottom, as indicated by the arrow. It is clear that the frame 32, 33 in the brewing process relies not on the cover 4 capsules, but the elements coffeemakers (not shown). Of course, the brewing water can be fed into the capsule also on the other side, i.e. the side cover 4.

Finally, figure 6 depicts a fifth exemplary embodiment capsules, in which the lower collection 36 rests on the bottom 7 of the capsule by means of a strong compression of the frame 35.

7 frame of figure 5 and 6 show in cross section along the line VII-VII of figure 6. Can be seen, in particular, the annular inner portion 33 and the vertical ribs 37.

If the distributor or collector, as shown in some of the previous examples, is separated from the bottom or cover, you can avoid cavities for placement of the punch as the punch after punching can enter into the free space between the bottom or, respectively, the lid and the valve or, respectively, the collector, not punching the last.

Instead of Central, made conical recess for placement of the punch may be provided, for example, also circular recess made in the conical section. Made such clicks the zoom deepening was asked for it, for example, when there are several distributed on a circular path of the mandrels. Instead performed conical recess for placement of the punch may be provided, for example, the recess is made spherical or in the form of a parallelepiped. To facilitate penetration by the punch of the bottom or cover the bottom or lid may be provided with a place of weakened strength (not shown). This place is weakened strength is made so that the top layer of the multilayer composite film, which is gas-tight, is not damaged.

Due to the above examples, portions of the capsules, you gain several advantages:

thanks to the dispenser across the section capsules are evenly distributed brewing water, which ensures a uniform extraction of the coffee powder. This is achieved also in the portion of capsules filled with coffee powder is not fully;

- out or wash-out of the coffee particles is substantially prevented, which reduces the clogging of coffee. In this regard, the size of the punched hole or holes is of secondary importance;

- the size of the punched hole or holes in relation to the speed of the flow is no longer attached decisive importance, since the brewing water almost regardless of who elicina punched hole or holes meets uniform resistance;

- capsules figure 2, 5 and 6 have universal application due to the fact that the brewing water can be directed through the portion capsule as top-down and in the opposite direction;

- on the side of the distributor or collector is required to provide only one punched hole.
