The level of technology

This invention relates to a portion capsule for preparing a beverage, having a capsule body with a capsule and side fill, and between the bottom side of the capsule and fill the hollow space for powder or liquid substrate beverage, and between the substrate and drink the bottom of the capsule filter element is located.

Such portions of the capsule, in General, known in the art. For example, in publications EP 1792850 B1, EP 1344722 A1 and US 2003/0172813 A1 discloses related portioned capsules for making coffee and espresso.

Preferably, such a portion capsule for preparing a beverage have the shape of a truncated cone or of a cylinder and is made, for example, formed by deep drawing of a synthetic film or molding under pressure. Usually they have an open filling side flange, which is joined by a heat-sealed or glued to the cover film, the closed bottom of the cover, and between the substrate and drink the bottom of the capsule is resting on the bottom of the capsule filter mesh particles. These strainers are manufactured from thermoplastic synthetic material by way of injection molding, or formed by deep drawing from a synthetic film or applied method Ho�one extrusion.

For speciality coffee portion capsule is inserted into the brew chamber of a coffee machine. Preferably after or during the process of closing the brew chamber capsule opens closed at its bottom side with located in a teapot, and the chamber of the punch, and after sealing the brew chamber closed with a cover film side fill portion of the chamber is pierced by piercing means. Then the liquid for cooking, preferably hot water, is supplied under pressure to the portion chamber. Liquid for cooking flows through the substrate of the drink and extracts and/or dissolves necessary for preparation of a beverage substances from the substrate of the drink. Coffee "espresso" for the extraction of essential oils on the coffee powder affects the pressure pot of water up to 20 bar. In addition, this pressure acts on the located between the coffee powder and the capsule is pierced and before the bottom of the capsule mesh filter.

However, the lack of mesh filters made by means of injection molding or deep drawing or cold extrusion, is that for the retention of particle hole coffee the mesh filter should be smaller than the smallest coffee particles. Since in the process of pomo�and the coffee is inevitably formed a certain amount of dust, when oversized holes of a strainer there is a passage of particles of coffee or with too small holes, especially at high pressures, there is a blockage of the strainer. In addition, for sensing pressure pot of water up to 20 bar and to prevent deformation of the mesh filters due to high pressure tea water (along with high temperature alarm water) is required beneath the mesh filters acting on the bottom of the capsule supporting elements. Negative, these supporting elements require additional material consumption, especially in the case of mesh filters made by molding under pressure, resulting in increased production costs.

The prior art discloses the portion of the capsule with mesh devices, which avoid these disadvantages. In US 2778739, EP 1710173 A1 and US 535765 uncovered portion of the capsule with mesh devices, which consist of saturates with relatively large through holes, and these holes are closed by the filter material. The disadvantage of these devices is that to perform these mesh devices have additional costs for material and manufacture, since they consist of a stationary saturates and located on siderately filter�existing material.

Like strainer with holes (cells) sieve and strainer with additional filter material is necessary to ensure that passing through the strainer ready to drink can flow to the outlet of the capsule, i.e. between the bottom of the capsule and the filter must be a free space to flow off the drink. In addition, these strainers require their own share of space in the portion capsule, which leads to an increase in the volume of the capsule and, therefore, inevitably to additional consumption of material.

Therefore, the object of this invention is to provide a portion of the capsule with the layout of the filter, which is more economical in comparison with the prior art and which at the same time it is possible to prevent the disadvantages mentioned in connection with the prior art.

This problem is solved by using a portion capsule for preparing a beverage, having a capsule body with a capsule and side fill, and between the bottom side of the capsule and fill the hollow space for powder or liquid substrate beverage, and between the substrate of the drink and the bottom of the capsule is a filter element, and wherein the filter element includes a nonwoven material, which is located in the bottom of the capsule.

Compared to� with the prior art portion capsule according to the invention has the advantage, what a simple and economical filter of nonwoven material is used as a strainer. Thus, it is possible to save on the costly process of plastic moulding under pressure or deep drawing or cold extrusion method for the manufacture of mesh filters. Thereby significantly reduced production costs. In addition, you do not need a supporting structure as a nonwoven material rests directly on the bottom of the capsule. Compared with the known from the prior art synthetic filter filter, non-woven fabric has the advantage that it has a substantially larger surface occurrences of the liquid. In addition, it becomes possible transverse fluid flow (parallel to the plane of the principal plane length of the filter), resulting in better mixing and swelling. In addition, it was found that when using the filter of nonwoven material is greatly reduced or nearly eliminated the risk of clogging of the mesh filter. Suddenly it became clear that the filter of non-woven material is resistant to blockage as in the preparation of beverages using liquid for cooking under a relatively low pressure, and in the preparation of beverages using liquid for cooking under a relatively high� pressure. In addition, in the filter of nonwoven material securely constantly maintained transverse flow of liquid and is provided by swelling entering the filter of nonwoven material liquid to the outlet. Despite this formed the so-called "foam", that is, the foam on the beverage, particularly coffee "espresso". The portion capsule in the sense of this invention includes preferably hermetically impermeable portion capsule. This means that in the portion capsule before extraction process drinks or food powder, such as coffee powder, soup powder or tea on the merits aromatherapies closed from the environment. But the portion capsule should not be hermetically sealed, and may also before applying to be in a hermetically impermeable packaging, which is then open, for example, manually.

Non-woven material in the sense of the invention is unordered, non-woven structure of fibers, especially synthetic fibers. Non-woven material in the sense of the invention preferably does not contain paper or bomgaars substances.

According to the following form of the present invention provides that the nonwoven fabric contains material from synthetic fibers, for example polyester fibres, which first of all�is about non-woven material with non-directed arrangement of fibers and/or nonwoven material with oriented arrangement of fibres. Preferably, the nonwoven material has a mass distribution (also called grammage, or weight per unit density) from 40 to 100 grams per square meter, particularly preferably between 60 and 80 grams per square meter, and most preferably essentially 70 grams per square meter. Preferably the filter element or the nonwoven fabric has a thickness of between 0.2 and 0.8 mm, particularly preferably between 0.3 and 0.35 millimeters, and most preferably essentially 0.32 millimeter. The nonwoven material is made so that the air permeability of nonwoven material at a pressure of 100 Pascals is preferably between 1000 and 3000 l/(m2h), particularly preferably between 1500 and 2500 l/(m2h), and most preferably essentially 2000 l/(m2h). Suddenly and unpredictably, it turned out that using such non-woven materials to achieve the optimum results regarding the effectiveness of extraction, mixing and flow off, and resistance to blockage and, in spite of this, a "foam".

Preferably, the nonwoven fabric is located at the bottom of the capsule so that it is applied to the largest area. Particularly Preferably, the nonwoven fabric is connected to the bottom of the capsule by heat sealing, especially by ultrasonic thermos�RCTs. Further, it is preferable to improve fit to the bottom of the nonwoven fabric is stretched in front of its attachment to the capsule, above all to the bottom of the capsule.

When you open the capsule by perforating tools is preferred if the tool pushes the nonwoven fabric from the bottom of the capsule and thus pulls or additional stretches. With perforating tool can penetrate into the nonwoven fabric and/or to pass through. Preferably, the size of the nonwoven fabric is larger than the size of the bottom of the capsule to which it is adjacent, so that the nonwoven material protrudes slightly over the edge.

According to the next subject or the next form of the present invention the filter element has a felt structure. First of all, we are talking about non-woven product obtained needle-punched method. Preferably the filter element is comprised of at least one of the felt structure and a supporting structure, particularly a fabric structure, and felt particularly preferred structure, at least one partial section of the volume comprises a supporting structure. Preferably a felt structure extends over the entire cross section of the bearing structure, but preferably only on a partial region of the height. Preferably felted structure of the soya�of inen with the bearing structure of the power and/or continuous connection. Preferably, the filter element has two or more felt structures, which are separated from each other by the bearing structure. The thickness of the two felt structures may be the same or different. Preferably converted to the powder or tea felted structure thinner than the facing to the bottom of the capsule of the felt structure or Vice versa. Preferably, the surface of the felt structure is subjected to processing, such as heat treatment for fixation, for example, weak fibers. Preferably have felt the structure of the filter element only put in the capsule, particularly at its bottom. But the filter element may be coupled to the capsule, especially with her bottom, especially with a solid connection. When perforation perforating tool can penetrate this filter element. Preferably in a capsule on top of each other are optionally connected to each other, several filter elements, which have one or more felt structures and load-bearing structure.

Filter element with felt structure has the advantage that coffee, espresso coffee or the like is not formed "foam", or that on tea bubbles do not form.

The supporting structure, particularly a fabric structure, and having felt the structure of the filter element are made, e.g.�measures through what is provided by a fabric structure comprising longitudinal and transverse threads. For construction of felt, first of all non-woven products, obtained needle-punched method, fibers are preferably selected from 0.8 to 7 dtex. The connection of the individual fibers with each other in a felt and/or its anchoring in the carrier structure preferably takes place through the process of hypoproteinemia. When this needle with reverse hooks are stuck at high speed in the existing package of fibers and again pulled. Thanks to the hooks of the fiber through the many emerging loops are woven with each other and/or with the cloth-backing.

The carrier element having one or more felt structures, preferably has a distribution of mass (also called grammage, or weight per unit density) between 100 and 800 grams per square meter, particularly preferably between 200 and 650 grams per square meter, and most preferably essentially 150-250 grams per square meter and tea 600-700 grams per square meter for coffee, espresso coffee or similar. The filter element or the nonwoven fabric preferably has a thickness of between 0.8 and 3.3 millimeters, particularly preferably between 1.1 and 3.0 millimeters, and most preferably 1,2-1,4 mm for prigotovleniya and 2,6-3,0 coffee.

According to the next subject or the next form of the present invention provides that the filter element contains a spongy material with open pores and/or foam material with open pores. Suddenly and unpredictably, it turned out that the aforementioned advantages compared with the prior art, such as, for example, lower production costs, resistance to blockage, the transverse fluid flow and better mixing and swelling, can be achieved equally through the filter element, made in the form of a foam material with open pores and/or foam material with open pores. First of all, nonwoven material, foam material with open pores and a foam material with open pores in each case, the microporosity, which allow transverse fluid flow and, thus, provide resistance to blockage. Spongy material contains, for example, polyurethane foam with mesh structure.

Preferably the filter element, that is, for example, nonwoven fabric, felt, sponge material or foam material is simply inserted into the housing of the capsule and then either freely lies at the bottom of the capsule, or connects with them and/or the side wall of the capsule, first of all by joining by heat sealing, mainly ultrasonic welding, as long as the casing of the capsule is filled substrate of the drink. Preferably, the capsule body is made in the form of a truncated cone or cylinder-shaped and made of, for example, of synthetic material, natural material and/or biodegradable material formed by deep drawing of a synthetic film or molding of plastic under pressure. Preferably, the capsule body has a side fill the collar is attached to the heat-sealed or glued to the cover film. Alternative is accepted that the valve body and cap of the capsule are connected to each other by a mechanical method. The bottom portion of the capsule is preferably closed and preferably only in a teapot, and the chamber is punctured with acting from the outside on the bottom portion of the camera perforating means to create the outlet. Alternative it would also be permissible that the bottom portion of the capsule during manufacture is provided with an outlet, which is preferably closed by a sealing film. Then, the sealing film can be perforated using a perforating means and manually removed from the bottom of the capsule. Preferably, the filter of non-woven material is tear-resistant. In the case of sealing film we are talking about �sinteticheskoi film, which has at least one barrier layer, e.g. metal layer, the first aluminum layer. It is preferable for relatively easy separation of the synthetic film from the bottom of the capsule synthetic tape on it facing to the capsule side has a "separation layer".

Preferably the outlet opening is formed of such size that it can accept contactless, where necessary, existing perforating tool. Particularly preferably the outlet opening is of such size that when draining prepared beverage does not occur a significant loss of pressure, especially that it does not lead to a meaningful twirl-ready beverage that could lead to the gas inlet to the beverage and thereby to foam.

According to the next subject or the next form of the present invention provides that the filter element is elastic and, at least in its edge region is located and/or mounted in the bottom of the capsule. If the capsule is punctured outer perforating means, the filter element in contact with the perforating means may be owing to its elasticity to yield or stretch so that the perforation of the filter element is prevented. This eliminates the danger that the filter �the entries perforated perforating means, and beverage forming substance will be released from unfiltered portion of the capsule. A fixed gap between the filter element and the bottom of the capsule, as known from the prior art, is not necessary, as this distance is achieved automatically perforating means. Thus, the filter element under collection occurs to last through the filter element forming the beverage liquid.

According to the next subject or the next form of the present invention provides that the filter element is pulled, nakalyaetsya and/or pierced perforating tool.

According to the next subject or the next form of the present invention provides that the filter element is located in a hollow space and rests on the side of the bottom of the capsule facing the side of the fill. The preferred way to significantly reduce production costs, since the filter element is only freely inserted into the portion capsule. Preferably, the fixation of the filter element takes place by forming a beverage substance, which when filled, portion of the capsule is located on the filter element and, thus, presses the filter element.

According to the next subject or the next form of implementation of the Dunn�th invention is provided, what is the diameter of the filter element is larger than the diameter of the bottom of the capsule. The preferred way, when filling in portions of the capsule substrate beverage filter element is pressed against the bottom, and the protruding edge region inevitably adjacent to the area of the side wall portions of the capsule and separated in the direction of the side fill or bent in the direction of the side fill. This has the advantage that when the Central region of the filter element is lifted from the bottom due to mechanical contact with the penetrating from the outside in the region of the bottom of the perforating means, the outer region slides towards the bottom of the capsule, so that the beverage forming substance does not leak unfiltered on the edge of the filter element by the filter element in the direction of the outlet. This makes it possible to pripodnimanie filter element from the bottom of the capsule also when using inelastic filter element, without damaging the effectiveness of the filter. The elastic filter element pripodnimanie Central area, without harming the effectiveness of the filter by sliding the outer region of the filter element affects at least favorable, as in the case of perforation of the bottom of the capsule, it is possible the combination of stretching and slipping Fi�Trouser element.

According to the next subject or the next form of the present invention provides that the filter element has an edge region that is essentially in the direction of filling and/or bent in the direction of the side fill. Thus, also can be achieved with the above benefits, as a consequence, the marginal region slides towards the bottom of the capsule or in the direction of the Central region as soon as the filter element is lifted in the Central region.

According to the following form of the present invention provides that the edge region extends at least partially along the side wall of the housing of the capsule, and the region of the side wall extends between the party and fill the bottom of the capsule. The preferred image of the boundary region when completing the portion of the capsule is pressed beverage forming substance out to the area of the side wall, thereby providing improved sealing action between the area of the side wall and the filter element. First of all, when the above-described sliding the filter element is prevented unhindered flushing of the filter element tea water.

According to the following form of the present invention provides that the filter elem�NT completely or only partially covers the bottom of the capsule. First of all, is sufficient if the filter element is located exclusively in the area of the perforation or in the area of the outlet openings in the bottom of the capsule.

According to the following form of the present invention provides that the filter element is fixed to the capsule, wherein the filter element is fixed to the capsule preferably by means of a continuous connection, primarily by joining by heat sealing. Thus the preferred way prevents the slipping of the filter element. Preferably this fastening takes place by means of ultrasonic welding.

According to the following form of the present invention provides that the filter element in the outer region of the bottom of the capsule is fixed to the capsule and/or filter element in the outer region of the filter element is attached to the side wall. Thus the preferred way prevents the slipping of the filter element and increases the sealing action between the housing of the capsule and the filter element, but simultaneously made it possible to pripodnimanie filter element in its Central region. In this case the filter element is preferably made flexible.

According to the following form of the present invention con�being finished the bottom of the capsule has a bulge on the opposite side of the fill direction. The preferred way bulge is for receiving perforating means so that when sticking perforating means in the bottom of the capsule is the perforation of the bottom of the capsule in the area of convexity, but then perforating tool remains in the hollow space of convexity. This prevents the perforation of the filter element. First of all, in this form of the invention does not require pripodnimanie filter element perforating means. However, the filter element may be formed so as to rise with perforating means, in any case, to exclude erroneous perforation.

According to the next subject or the next form of the present invention provides that the filter element is designed so that when the perforation of the bottom of the external capsule perforating means at least partially occurs pripodnimanie filter element from the bottom of the capsule. Thus, due to the perforating means prevents the perforation of the filter element.

According to the following form of the present invention provides that the filter element is lifted from the bottom of the capsule only in the Central area, and in krajova� the bottom of the capsule he continues to lie on the bottom of the capsule or attached to the bottom of the capsule. Thus the preferred way prevents the slipping of the filter element and increases the sealing action between the housing of the capsule and the filter element, but also simultaneously made possible pripodnimanie filter element in its Central region. In this case the filter element is preferably made flexible.

According to the next subject or the next form of the present invention provides that the filter element is made so that when the perforation of the bottom of the external capsule perforating means of the filter element rises in its Central region from the bottom of the capsule, and the marginal region of the filter element, located at a first direction side of the fill, at least partially, moves towards the bottom of the capsule. Thus, it can be achieved the above advantages, resulting in marginal region slides towards the bottom of the capsule or in the direction of the Central region, as soon as a filter of nonwoven material rises in the Central area by perforating means, so that the beverage forming substance does not leak unfiltered on the edge of the filter element by the filter element in the direction of the outlet.

According to the following form of implementation�display of the present invention is provided, that the filter element has a storage material. A preferred manner, the drive of the material makes it possible to pripodnimanie filter element in its Central region from the bottom of the capsule, although the filter element in its Central region rigidly (primarily by means of a continuous connection) is connected to the bottom of the capsule and performed essentially inelastic. The drive of the material primarily contains corrugated or folded region in the filter element, which is partially smoothed, when the Central region with perforating means is lifted from the bottom of the capsule. This ensures that when the perforation of the bottom of the external capsule perforating means of the filter element is pushed from the storage material in the Central area, so that due to lift is compensated by increasing the surface of the filter element with material from the storage.

According to the following form of the present invention provides that the bottom of the capsule has a specified place of destruction, which is provided in order to burst through mechanical contact with external perforating means, and a specified place of destruction preferably contains many lines of weakening arranged star-like around a Central point�and bottom of the capsule. Preferably, the bottom of the capsule has a reduced material thickness along lines of weakening and/or perforated along lines of weakening. The preferred way whether the specified place of destruction has a positive effect on the perforation of the bottom of the capsule. In addition, it has the advantage that, for perforating the bottom of the capsule can be used in less acute perforating the edge, so that through the use of perforating the edge significantly decreases the risk of damage to the filter element when pripodnimanie. First of all, now for perforating the bottom of the capsule is sufficient to blunt perforating tool.

According to the following form of implementation of the bottom of the capsule has an outlet opening which is preferably sealed with film, and film, particularly preferably has a tongue tie for the contraction of the film manually. In this preferred manner does not require perforation of the bottom of the capsule by an external perforating means. Before insertion of the portion capsule in a teapot, and the camera, the film simply pulls from the bottom of the capsule by means of tension of the tongue, and the brewing process can begin. The combination of pre-fabricated and thus a relatively large orifice with filter insert of nonwoven material, felt, before the sun�th non-woven products, the obtained needle-punched method, foamy or spongy materials has the advantage that the beverage forming fluid is discharged from the outlet is not under high pressure and, thus, prevents the formation of foam ("foam"), particularly when cooking, American coffee or tea.

Following the subject of this invention is a method of manufacturing a capsule according to the invention, characterized in that the filter element is cut from a strip of material embedded in the capsule. Preferably cut the filter element, at least a section of track moves clip knife, especially hollow knife. Preferably cut the filter element is transported further from the waveguide hub, used for ultrasonic heat sealing, and/or is pressed against the capsule, particularly its bottom.

Following the subject of this invention is a method of preparing a beverage from portioned capsules, and in the second step of the method of the capsule is perforated by a perforating means, and wherein in the third step of the method the filter element, at least partially, is located at a distance from the bottom of the capsule. The third step of the method, the filter element is lifted perforating device from the bottom of the capsule in such a way�m, he is at a distance from the perforated bottom of the capsule. The bottom of the capsule is punctured in the area of Central point, while in the outer region preferably continues to lie at the bottom of the capsule or remains fixed at the bottom of the capsule. Thus, by lifting the Central region is not deleterious effect on the sealing action between the housing of the capsule and the filter element.

According to the following form of implementation provides that the filter element at the location of the Central region at a distance from the bottom of the capsule at least partially stretched. Thus, it is possible for a solid attachment of the outer region of the filter element at the bottom of the capsule, whereby the filter element may rise in the Central region from the bottom of the capsule. Thus, the advantages of maximum sealing action connected with the advantages of ascending filter element.

According to the following form of implementation provides that the edge region of the filter element, spaced in the direction of the bottom of the capsule, is shifted during the third step of the method towards the bottom of the capsule. Thus, it is prevented that forms the drink the unfiltered liquid enters in the direction of the outlet hole�Oia, when the Central region is lifted from the bottom of the capsule.

According to the following form of implementation provides that when the location of the Central region at a distance from the bottom of the capsule during the third step of the method, the material of the filter element from the storage material is shifted in the direction of the bottom of the capsule, particularly corrugated or folded region of the filter element at least partially smoothed. Thus, it is also possible for the fastening by means of a continuous connection of the outer region of the filter element at the bottom of the capsule, whereby the filter element may still rise in the Central region of the bottom of the capsule. Preferably, the storage material extends around the Central region of the filter element.

Thus, between the bottom 3 of the capsule and the cover film 6 is made preferably air - and aromatherapies closed hollow space 100, which is filled with powdery and granular substance 101 to prepare the drink. Thus forming a beverage substance 101 contains, for example, coffee, cocoa, tea and/or milk powder (or granules). On the inner side 3A of the closed bottom 3 of the casing of the capsule, i.e. inside the hollow space 100, is the filter element 7 consisting of a filter of non-woven mate�ial or sponge or foam material. The filter element 7 is either desacralize on the inner side 3A of the bottom 3 of the capsule, or is stationary, i.e. fixed, preferably by means of a continuous connection, with the inner side 3A of the bottom 3 of the capsule housing. In the second embodiment, the filter element 7 is attached by means of a continuous connection only in the outer region 3' of the bottom of the capsule on the bottom 3 of the capsule.

Preferably, the nonwoven material contains a material made of thin polyester fibers. The fibers are thermally connected to each other, particularly preferably by means of a calender, for example a lot of the extruded fibers are arranged on top of each other and next to each other and then fortified with heated rolls (flat calendering). The nonwoven material contains a material with a non-directed arrangement of fibers and/or nonwoven material with directional fibers.

Preferably, the nonwoven material contains a distribution of mass (also called grammage, or weight per unit density) between 40 and 100 grams per square meter, particularly preferably between 60 and 80 grams per square meter, and most preferably essentially 70 grams per square meter. The filter element or the nonwoven fabric preferably has a thickness of between 0.20 and 0.8 mm, particularly preferably between 0.25 and 0.39 mill�meters and particularly preferably essentially 0.32 millimeter. The nonwoven material is made so that the air permeability of nonwoven material at a pressure of 100 Pascals is preferably between 1000 and 3000 l/(m2h), particularly preferably between 1500 and 2500 l/(m2h), and most preferably essentially 2000 l/(m2h). In addition, the nonwoven material is made so that the maximum tensile force in the longitudinal direction is essentially 100 Newtons per 5 cm in the transverse direction on the merits of 67 Newtons per 5 cm, and the maximum tensile strain in the longitudinal direction is essentially 30 percent and in the transverse direction essentially 38 percent.

Fig.2 shows a shown in Fig.1 portion capsule 1 according to the first form of the present invention, with the portion capsule 1 in Fig.2 is in a closed pot for the camera 8. Brew chamber 8 consists of a first element 9 of the brew chamber and the second element 10 tea chamber, with the first element 9 of the brew chamber to enter the portion capsule 1 is provided movable relative to the second element 10 tea camera or Vice versa. Between the two elements 9, 10 tea chamber is located a seal 11. The first element 9 tea camera SOS�Oita on the merits of the locking plunger 12 with piercing elements 13A, 13b for opening a cover film portion 6 of the capsule 1, channel 14 supplying liquid to prepare a beverage, and a seal 11. The second element 10 tea camera 10 consists essentially of cone 15 tea chamber partially surrounding the portion capsule 1 is located at the bottom of the cone 15 tea camera by a punch 16 which is provided with drain grooves 17 and the outlet 18 to drink. To accommodate the portion capsule 1 tea camera 8 is not shown in an open state in which the first and second elements 9, 10 alarm camera are located at a distance from each other to ensure the supply portion of the capsule 1, and depicted in a closed state in which by means of a portion capsule 1 can carry out the process of preparation of the drink. In the closed state brew chamber 8 is hermetically closed. When translating brew chamber 8 from the open state is depicted in a closed state of the cover film 6 is pierced piercing elements 13A, 13b, so that the liquid for cooking, especially hot tea water, through the channel 14 of the liquid for preparing a beverage under pressure enters the hollow space portion 100 of the chamber 1. In addition, when closing the brew chamber 8, the bottom 3 of the capsule is punctured is made in the form of the punch 16 perforating tool h�about in portion capsule 1 creates an outlet 107, through which the prepared beverage forming liquid may withdraw from a portion of the capsule 1 in the flow direction 18 to drink.

In the image, the bottom 3 being in a teapot, and the chamber 9, 10 of the portion capsule 1 is pierced by a punch 16 of the second element alarm camera, but lying above the puncture the filter element 7 is slightly raised piercing tip 19 of the punch 16, but not pierced. This is primarily achieved by the fact that the Central area 7” is not connected to the bottom 3 of the capsule by means of a continuous connection, and the filter element 7 is connected with the bottom 3 of the capsule by means of a continuous connection only in the outer region of the 3' DNA 3 capsules, so it is due to mechanical contact with the punch edge only 16 is lifted from the bottom 3 of the capsule and, thus, remains non-perforated (i.e., not perforated by the punch 16). In the outer region of the 3' DNA 3 capsules or in the outer region 7' of the filter element 7 of the bottom 3 of the capsule and the filter element 7 remain in contact with each other and above all are interconnected by means of a continuous connection, so forming the beverage substance 101 misses around the filter element 7 to the drain 18 to drink. The bottom 3 �apsule has in its Central point 106, in which the bottom 3 of the capsule is punctured by the punch 16, the optional specified position 104 of destruction, so that the perforation of the bottom 3 capsules a relatively blunt punch 16 and, thus, eliminates the risk that the punch 16 will also be mistakenly perforated filter element 7.

Fig.3 shows a portion capsule 1 according to the second form of the present invention, the second form of implementation is essentially similar to that shown in Fig.2 the first form of implementation, and the portion capsule 1 is also depicted in a closed pot for the camera 8. Unlike the first form of implementation, the bottom portion 3 of the capsule in the area of perforation of the punch 16 has a policy against recess 20 in the bottom of the tea 3A camera bulge 21 (thus, the bulge 21 is directed in the opposite side 4 of the fill direction), which stuck the punch 16, not punching with the filter element 7. Thus, first of all not required pripodnimanie filter element 7 from the bottom 3 of the capsule. To make the drink after you enter the portion capsule 1 in the brew chamber 8 of the brew chamber 8 is closed. During the process of closing the cover film portion 6 of the chamber 1 is punctured with piercing means 13A, 13b, and after successfully entering and sealing the first and second elements�and 9, 10 tea camera (by a seal 11) tea water is supplied through the inlet 6 of the liquid. In the same way during the process of closing the brew chamber the punch 16 punches a hole in the bottom portion 3 of the chamber 1. Lying above the puncture site filter element agreed by its thickness and tensile strength with the depth of penetration of the tip 19 of the punch 16 so that the filter element 7 is not pierced. Alternative filter element 7 lies on the bulge 21 of the bottom 3 of the capsule, which lies in the dredging 23 tea cone, and the punch 16 is inserted only in the bulge 21 of the bottom 3 of the capsule and does not reach the filter element 7. The liquid is then that in the preparation of coffee is, for example, hot water flows into the capsule 1. In this capsule, the liquid flows through the substrate 101 of the drink and extracts and/or dissolves required to prepare a beverage substances from the substrate 101 of the drink. Fluid flow in the substrate 101 of the drink is shown by the reference symbol 22. After that, the beverage flows through located between the substrate 101 of the drink and the bottom 3 capsule filter element 7, which prevents the component parts of the substrate 101 of the beverage in the form of particles in the beverage, and punched through by the punch 16 in the bottom 3 capsules a hole and waste the grooves 17 of the punch 16 Dale� into the receiving vessel, for example a Cup or a teapot.

Fig.4A and 4B depict schematic views in section of a portion capsule 1 according to a third form of the present invention, a third form of implementation is in essence similar to the first form of implementation shown in Fig.1 and 2, and the filter element 7 is made of elastic. Fig.4A the portion capsule 1 is in its initial position, while in Fig.4B, it is shown perforated perforating means 16 (the portion capsule 1 is in Fig.4B is not shown in more tea cell 8). Due to the elastic design of the filter element 7, the filter element 7 in its Central region 7” in mechanical contact with the perforating means 16 is stretched in the direction of the side 4 of the fill without perforating or tearing from the perforating means 16. In the outer region of the bottom 3' of the capsule filter element 7' remains firmly connected or connected by means of a continuous connection with the bottom 3 capsules, so forming the beverage substance 101 misses from the hollow space 100 by the filter element 7 in the direction of the outlet 107 made by the perforating means 16.

Fig.5A and 5B depict schematic views in section of a portion capsule 1 according to the fourth form of the present invention, p�eacham fourth form of implementation is in essence similar to the third form of implementation, shown in Fig.4A and 4B. But the filter element 7 is made stiff and almost completely lifted perforating means 16 from the bottom 3 of the capsule. Since the area of the base of the filter element 7 is almost not changed, the edge region 7' of the filter element are shifted inwards, i.e. in the direction of the center point 106 of the bottom 3' of the capsule.

Fig.6A and 6B depict schematic views in section of a portion capsule 1 according to the fifth form of the present invention, and a fifth form of implementation is in essence similar to the fourth form of implementation shown in Fig.5A and 5B. The filter element 7 first of all, is flexible and has a footprint that is larger than the area of the bottom base 3 capsules. This leads to the fact that marginal area 7' of the filter element 7' is shown in Fig.6A the initial position of the portion capsule 1 is adjacent to the bottom 102 of the side wall of the casing 2 of the capsule, which extends from the flange 5 to the bottom 3 of the capsule. When the bottom 3 of the capsule is punctured perforating means 16 and the filter element 7 in its Central region 7” lifted perforating means 16 from the bottom 3 of the capsule, the edge region 7' of the filter element moves towards the bottom 3 of the capsule. This ensures that the edge region 3' of the bottom 3 capsules constantly about�remains covered with the filter element 7 and, thereby forming the beverage substance 101 misses unfiltered by the filter element 7 in the direction of flow 18.

Fig.7A and 7B depict schematic views in section of a portion capsule 1 according to the sixth form of the present invention. The sixth form of implementation is in essence similar to the fourth form of implementation shown in Fig.5A and 5B, and the filter element 7 has a storage device 103 of the material. The storage device 103 material comprises a corrugated region 103', i.e. the area in which accumulates excess material of the filter element 7. When the Central area 7” lifted perforating means 16 from the bottom 3 capsules, a tensile force acting on the storage device 103 of the material, whereby the corrugated region 103', at least partially aligned and, thus, there is enough material for the Central area 7” could be lifted sufficiently and avoid breakage or perforation of the filter element 7.

Fig.8A and 8B shows a view of the bottom 3 of the capsule 1 according to the seventh form of the present invention, the seventh form of the implementation is in essence similar to the first form of implementation shown in Fig.1 and 2, with the portion capsule 1 in Fig.8 shows a "bottom". On this form you can recognize the optional engine speed specified�place 104 of destruction, which contains three lines 105 attenuation that have a star shape and are arranged in radial direction around a center point 106 on the bottom 3 of the capsule. Along the lines 105 of the weakening of the bottom 3 of the capsule has a reduced material thickness and/or the bottom 3 capsules pre-perforated to favored perforation using a camera. To the aroma of forming a beverage substance 101 and also with pre-perforated bottom of the capsule was maintained for a long period of time, the bottom 3 capsules, at least in the area of the specified space 104 preferably sealed with puncked or manually contractible film 108. Film 108 is glued, for example, on the outer side of the bottom 3 of the capsule and is provided with a coupling tongue 109 which does not stick to the bottom 3 of the capsule and for which film 108 may be manually tightened. Proforma implementation with lines 105 attenuation in the form of perforations in the bottom 3 capsules, as well as with film 108 shown in Fig.8B.

Fig.9 shows a view of a portion capsule 1 according to the eighth form of the present invention. The eighth form of the implementation is in essence similar to the first form of implementation shown in Fig.1, with the portion capsule 1 eighth form of the implementation is equipped with a permanent outlet opening 107 in the bottom 3 of the capsule, which in the initial position sealed p�encou 108. Therefore the portion capsule 1 is not specified the places of destruction. Film 108 also has a tongue tie 109 for tightening film 108 manually. Perforation of the bottom 3 of the capsule by an external perforating means 16 is not provided. On the contrary, by inserting the portion capsule 1 in the brew chamber 8 film 108 just pulled from the bottom 3 of the capsule by means of tension of the tongue 109, and the brewing process can begin immediately and without perforating the bottom 3 of the capsule.

Fig.10 and 11 show the following form of the present invention. In this case, the filter element 7 is formed so that the perforating means 16 when the penetration into the capsule stretches, irezumi (Fig.10) and/or puncture the filter element, the filter element is at least portions connected by means of a continuous connection, for example, with the bottom of the capsule, is provided adjacent to the bottom for more surface and/or tense.
