The invention relates to a capsule for the content of the ingredients for the drink, and the capsule is configured to be inserted into the device for preparing a beverage, in which fluid under pressure enters the capsule for draining of the beverage from the capsule, and the capsule contains an annular first wall, a second wall closing the annular first wall at the first end, and a third wall, closing the ring the first wall to the second, open end, an opposite second wall, the first, second and third walls enclose an inner space containing the ingredients for the drink, the capsule contains a sealing element to effect a seal between the capsule and device for preparation of a drink.

EP1700548 (EP'548) discloses a capsule containing a Cup-shaped main body and a closing foil element. Known capsule is configured to be inserted into the device for preparing a beverage, in which fluid under pressure enters the capsule to interact with the ingredients in the capsule for draining of the beverage from the capsule.

In accordance with EP'548 necessary to ensure that during operation, only the flow of water, in fact, takes place through the interior of the capsule and that the water cannot flow from the water injector into the gap between the annular cover is yuushin element and the outer part of the capsule and then into the channel for draining device. In accordance with EP'548 known in any stream of water external to the capsule stops by sealing coupling, which is achieved by concatenating compressed between the ring element, lanzoprazol edges of the side wall of the capsule holder capsules.

Also in accordance with EP'548 may be provided by the improvement in accordance with which the sealing coupling is further enhanced by coating the internal wall of the annular element rubber/elastic material. In other words, in accordance with the approach o the clutch is provided with structures attached to or connected to the device for preparation of a drink.

EP'548 seeks to improve the sealing of the coupling located between the inlet for the liquid and the side draining drink this system for a beverage. For this purpose EP1700548 proposes to transfer the elastic part of the sealing coupling with a device for preparing a beverage in the capsule. The advantage is that any elastic sealing element is used only once (i.e. only with the associated capsule), thus can be guaranteed the proper functioning of the seal and may not be hygienically the problems in the sealing element. According EP1700548 capsule contains a special hollow sealing element on the outer surface of the capsule to achieve the effect the seal between the covering element of the device for preparing a beverage holder capsules (cooking appliances).

The present invention seeks to provide improvement capsules. In particular, the invention seeks to provide a capsule that may solve or reduce the above problems, and the capsule can be made efficient, cost-effective way.

In this application, the same or corresponding elements are denoted by the same or corresponding reference positions.

In Fig.1 shows a system 101 for preparing a predetermined quantity of beverage suitable for consumption using an extractable product. The system 101 includes a removable first capsule 102 and the device 104. In this example, the device 104 includes a receiver 106 for holding the exchangeable capsule 102. In Fig.1A, the gap shown between the capsule 102 and when is the MSC 106 for clarity. It should be understood that when using the capsule 102 may be in contact with the receiver 106. Usually, the receiver 106 may have a shape corresponding to the shape of the capsule 102. The device 104 further comprises a device 108 for filling fluid for supplying a quantity of fluid, such as water, under pressure, for example in bar 9, the exchangeable capsule 102.

As follows from the drawing, the exchangeable capsule 102 may include an annular wall 110, a bottom portion 112, closing the annular wall 110 at the first end 114 and the cover 116, closing the annular wall 110 at the second end 118 opposite the lower part 112. The annular wall 110, a bottom portion 112 and the cover 116 enclose the inner space 120, containing the extracted product.

The system 101 of Fig.1 contains these means 122 to the bottom, designed to pierce the capsule 102. In Fig.1 shows these means 122 for the lower part in the designated position. When connectors are the means 122 for the lower part is in its extended position (not shown), it can perform an inlet opening in the lower part 112 capsules for supplying the fluid to the extractable product through the inlet. For example, these tools 122 may contain the channel 126 through which fluid may be fed into the capsule. The system 101 of Fig.1 which contains additional connectors means 128 for the cover, implemented here in the form of protrusions designed to puncture the lid 116 of the capsule 102. For example, these means 128 for the cover can be a part of the holder 190 capsules (see Fig.1-2).

The system 101 shown in Fig.1, may operate as described below to prepare a Cup of coffee, while the extractable product is a roast and ground coffee (see also content ER). During operation, the capsule 102 is placed in the receiver 106 (see Fig.1). The receiver 106 and the holder 190 capsules can hold the capsule 102 between them. In particular, the receiver 106 and the holder 190 capsules can be movable towards each other, in a state of holding the capsule for holding the capsule between them and from each other to release the used capsules and for locating the capsule.

During operation, when the capsule is held between the receiver 106 and the holder 190, these means for the lower part are driven to pierce the lower part 112 of the capsule 102 to perform the inlet. Fluid here is hot water under pressure is fed to the extractable product in the inner space 120 through the inlet. Water will moisten coffee grounds and will extract the necessary substances for the formation of a coffee drink. For example, during the supply of water under pressure in nutrena space 120 pressure inside the capsule 102 will grow. The increase in pressure will cause the cover 116 to deform and to cuddle up to these means 128 for cover. As soon as the pressure reaches a certain level, the tensile strength of the cover 116 is exceeded and the lid will break on these means 128 for the cover, performing outlets. Ready coffee is drained from the capsule 102 through the outlet 130 and releases 132 receiver 106 and can be served in the capacity of, for example, a Cup (not shown).

During operation, in particular when the receiver 106 and the holder 190 capsules have been moved towards each other and hold the capsule 102 between them, preferably, provided that only the flow of water, in fact, takes place through the interior of the capsule 102. In the known system the flow of water external to the capsule stops by sealing coupling, which is achieved by concatenating compressed between the ring element of the receiver, lanzoprazol edges of the side wall of the capsule holder capsules. In an alternative capsule includes a special hollow sealing element on the outer surface of the capsule to achieve the effect the seal between the covering element of the device for preparing a beverage holder capsules device for cooking.

In Fig.2 shows alternative options, the ant implementation of a system 1 for preparing a predetermined quantity of beverage, suitable for consumption using an extractable product. This system 1 contains exchangeable capsule 2 and the device 104. The device 104 includes a receiver 106 for holding the exchangeable capsule 2. In this example, the receiver 106 has a shape corresponding to the shape of the capsule 2. In Fig.2 the gap depicted between the capsule 2 and the receiver 106 for clarity. It should be understood that when using the capsule 2 may be in contact with the receiver 106. The device 104 further comprises a device 108 for filling fluid for supplying a quantity of fluid such as water under pressure to the exchangeable capsule 2.

In the system 1 shown in Fig.2, the exchangeable capsule 2 contains an annular wall 10, bottom 12, end of the annular wall 10 at the first end 14 and a cover 16 that covers the annular wall 10 at the second end 18 opposite the lower part 12. The annular wall 10, the lower part 12 and the cover 16 enclose the inner space 20, containing the extracted product. In this example, the exchangeable capsule 2 contains some amount of extractable product, suitable for making single serving of a beverage, preferably a single Cup of beverage, for example, from 30 to 200 ml of ready-to-drink. Thus, the exchangeable capsule is a single-portion cassette.

The system 1 of Fig.2 may contain connectors with whom estva 122 for the lower part, designed to pierce the capsule 102, as shown in Fig.1. In Fig.2 shows the connectors are the means for the lower section in its extended position, designed to perform the inlet 124 in the lower part 112 of the first capsule 102. In accordance with the embodiment, the capsule 2 may include an input filter 34 (see Fig.3A-3d), which is located at a distance from these funds for the bottom part 12 so that the capsule 2 is not pierced by these means 122 for the lower part and the bottom part 12 remains intact when the connectors are the means for the lower part is in the extended position.

In Fig.2 these means 122 contain the channel 126 through which the fluid medium is supplied into the inner space of the receiver 106. Fluid here is hot water under pressure, for example, more than 6 bar, will flow through the input filter 34 in the inner space 20 of the capsule 2 to extract the necessary substances from the extracted product, in this example, approximately 4.5 to 8 grams, for example, 5-6 grams (or, for example, 7 grams) roasted and ground coffee, for cooking, in this example, one Cup of drink, here is the coffee.

Thus, in a more General example of Fig.2 the lower portion 12 includes an input region formed by the input filter 34, and the system 1 is to make the device 108 for filling fluid into an interaction in a fluid environment with an input area for supplying the fluid to the extractable product for preparing the beverage.

In the example of Fig.2 the annular wall 10, essentially, is hard. The annular wall may, for example, contain plastic materials and can be formed by, for example, the fill pressure injection, vacuum forming, high-temperature molding or the like. In the example of Fig.2 the lower part 12 is one piece with the annular wall. In this example, the input filter 34 is formed by a multiplicity of holes 24 in the lower part 12. In this example, the multiplicity of holes 24 are distributed essentially throughout the lower part 12. Thus, fluid is supplied to the extractable product through a set of openings 24 that leads to the wet extractable product, essentially over the entire cross section of the capsule 2. Therefore, achieves a very uniform flow of the fluid to the extractable product. Thus, the risk of preferred paths through which fluid flows in the extractable product, significantly reduced.

In accordance with an additional embodiment, the system 1 of Fig.2 may contain these means 128 for the cover, designed to pierce the cover 116 of the first capsule 102 when the cover 116 is sufficient pressed against these means 128 for cover under the action of the Alenia fluid and/or beverage in the capsule 102, to perform at least one outlet opening 130 through which the beverage can drain away from the capsule 102. In accordance with the embodiment, the capsule 2 may include an output filter 36 through which the beverage can drain away from the capsule 2. In this case, the output filter 36 preferably is located so that, with sufficiently high tensile strength, not to pierce through these means 128 for cover under the action of pressure inside the capsule 2. Alternatively or additionally, the output of the filter 36 may be set relatively weak resistance to the flow of beverage exiting the capsule 2, such that the output of the filter 36 is not pressed against these means 128 for a cover with sufficient force to pierce through these means 128 for the cover, and the cover remains intact. Therefore, the output of the filter 36 is adapted to these means 128 for the cover so that the capsule 2 when using not pierced through these means 128 for the cover, and the cover 16 remains intact. More in General, it is used for the output filter 36 and connectors means 128 for a cover adapted to each other so that the capsule 2 when using non-punctured through ProCal what that means 128 for the cover and the cover 16 remained intact.

In the example of Fig.2 output filter 36, which forms the output region of the capsule 2 through which the drink, here is the coffee, may be discharged from the capsule, made of porous sheet material, such as filter paper. In this example, all the cover 16 is formed as the output of the filter 36. In the example of Fig.2 capsule 2 includes passing the outside of the rim 38 at the second end 18, the lid 16 is attached to passing the outside of the rim 38, for example, by gluing, welding or the like. Therefore, in this example, the output filter 36, i.e., porous sheet material attached to passing the outside of the rim 38.

In this example, the output filter 36 forms an essentially continuous impermeable to the fluid sheet material, covering essentially the entire second, open end 18 of the capsule 2. Thus, fluid may be discharged from the capsule 2 over a large area. Therefore, achieves a very uniform draining of the beverage from the extracted product. Thus, the risk of preferred paths through which fluid flows in the extractable product, significantly reduced.

In General, the parameters of the output filter capsules 2 system 1 can be selected so that the output filter is not torn or broken, for example, had a fairly high is rocheste to break and/or forming the sufficiently low flow resistance, not to be pierced or torn. It should be understood that the cover and/or output filter may be deformed by these means for the cover, although it will not break or be broken. When the output of the filter 36, for example, made of filter paper, the parameters of the filter paper, for example, density, thickness and/or the content of polyethylene, can be easily selected for the output filter having a sufficiently high tensile strength and/or forming the sufficiently low flow resistance. Alternatively, when the output of the filter 36, for example made of a polymer film, made with lots of outlets, the parameters of the polymer foil, for example, density, thickness, number of holes, size and/or shape of the outlet openings can be easily selected to provide a third wall having a sufficiently high tensile strength and/or forming the sufficiently low flow resistance.

In the example of Fig.2 these means 128 for the cover shown with sharp teeth, all designed to pierce the cover. It should be understood that, alternatively, these means 128 for the cover may have a blunt these surfaces, for example, as indicated by the dotted lines in Fig.2. In this version done by the means of the capsule 102, however, can pierce through these stupid tools 128, for example, when the cover 116 is composed of a sheet of aluminum foil. The parameters of the output filter capsule 2 can be selected so that the output filter of sufficiently high tensile strength and/or forming the sufficiently low flow resistance so as not to pierce or tear. It should be understood that when these funds to cover are stupid, the parameters of the output filter can be chosen in such a way, to get this stupid these tools. When these tools are blunt, the output filter can, for example, be thinner than when these funds to cover are sharp, while ensuring that the output filter has a sufficiently high tensile strength and/or forming the sufficiently low flow resistance so as not to pierce or tear.

Is it possible for these funds to cover contained the tabs that cover when using adjacent. Such protrusions can be formed by blunt these funds 128, as shown in dotted lines in Fig.2. The protrusions may, for example, be at least 10%, probably at least 25% of the part of the surface of the receiver 106, which in the line is the cation coincides with part of the surface area of the cover 16, overlapping the second open end 18. Therefore, when using the cover 16 may be supported by the ledges on, for example, at least 10%, preferably at least 25% of the side surface of the cover 16, covering the second open end 18. As already indicated, the cover 116 capsule 102 may pierce through such projections, despite the fact that the parameters of the output filter 36 capsules 2 system 1 can be easily selected so that the output filter of sufficiently high tensile strength and/or forming the sufficiently low flow resistance so as not to pierce or tear. It should be understood that when these funds to cover contain protrusions, the parameters of the output filter can be chosen in such a way as to approach such connectors are the means for the cover.

In the example of Fig.2 tabs contain edges that are not sharp. In this example, the radius of rounding of the edges is approximately 50 microns, although other radii are possible, for example, 100, 200 or 500 μm. Capsule 102, however, can pierce through these stupid tools 128, for example, when the cover 116 is composed of a sheet of aluminum foil. It should be understood that when these funds to cover contain mild edge, the parameters of the output filter can be in the gap so to get such connectors are the means for the cover. The parameters of the output filter capsule 2 can be selected so that the output filter of sufficiently high tensile strength and/or forming the sufficiently low flow resistance so as not to pierce or tear.

Is also possible that the tabs these means 128 for the cover had a convex vertex, which adjoins the cover 16. Therefore, when the cover when using pressed against the protrusions, the surface area on which the cover is supported by the protrusions increases, thus reducing the local pressure exerted on the cover tabs. Thus, it is possible to provide a simple way to ensure that the cover you are using are not torn and/or broke, but remained intact.

In Fig.3A-3d shows additional non-limiting embodiments of the capsule 2.

In Fig.3A the lower part 12 is one piece with the annular wall 10, as in Fig.2. Input filter 34 is formed by a multiplicity of holes 24 in the lower part 12. Output filter 36 is made of foil 40, for example a flexible polymer foil, performed with many of the outlet openings 30.

In Fig.3b the output filter 36 is made of a flexible porous sheet material, such as filter Boo is AGI, as shown in Fig.2. In Fig.3b input filter 34 is also made of a flexible porous sheet material, such as filter paper. In this example, the input filter attached to passing the inside of the rim 42. In this example, the input filter 34 is attached to the inner side of the going on inside of rim 42. This maximizes the internal volume of the capsule 2, since the thickness of the edges is not located in the internal space 20 of the capsule 2.

In Fig.3C is an output filter 36 is made of a flexible porous sheet material, such as filter paper, as in Fig.2 and 3b. In Fig.3C input filter 34 is also made of a flexible porous sheet material, such as filter paper. In this example, the input filter 34 is attached to the outer side of the going on inside of rim 42. Therefore, reduced the risk that fluid under pressure will break the input filter 34 passes the inside of the rim 42. Is it possible to input filter 34 were from the annular edge of the lower part. Therefore, more surface area is available for attaching the input filter 34 to the lower part 12 and the annular wall 10, resulting in a stronger connection.

In Fig.3d output filter 36 is made of foil 40, for example a flexible polymer foil, performed with many of the outlet openings 30, as in Fig.3A. In Fig.3d) the filter 34 is also made of foil 44, made with a multiplicity of holes 24.

In all variants of the implementation of Fig.3A-3d output filter is made of flexible sheet material. More specifically, in all variants of the implementation of Fig.3A-3d only cover is made of flexible sheet material. It was found that, in General, to maintain the output foil to prevent tearing and/or during the breaking of the output of the foil does not require support structures, such as, in essence, hard mesh, for example, further downstream relative to the exit foil.

In all variants of the implementation of Fig.3b-3d input filter is made of flexible sheet material. More specifically, in all variants of the implementation of Fig.3b-3d only input region is made of a flexible sheet material. It was found that, in General, to maintain the input foil to prevent during the breaking and/or destruction of the input foil does not require support structures, such as, in essence, hard mesh, for example, further downstream with respect to the input foil.

In all variants of the implementation of Fig.3A-3d output filter sets the outer limit of the capsule in its axial direction.

It should be understood that the capsule 2 may contain any of the input filter in accordance with any one of the shown embodiments in combination with any degree of the output filter in accordance with any one of the shown embodiments. Although not shown, it is possible to cover contained, essentially, a hard wall, made with the outlets 30.

In General, the outlet port 30 or the pores of the porous sheet material are of such size that the size of the holes 30 or pores was small enough to hold the extractable product, such as ground coffee inside the capsule 2. Also, in General, the inlet 24 or pores of the porous sheet material are of such size that the size of the hole 24 or pores was small enough to hold the extractable product, such as ground coffee inside the capsule 2.

In General, the inlet 24, preferably, is distributed essentially over the entire surface of the bottom or foil 44, at least essentially the entire surface of the holes, which are inside a given rim 42. Additionally, the inlet openings 24 are also located on the annular wall 10, for example, in the area of the annular wall 10 near the first end 14. This provides the ability to uniformly supply the fluid to the extractable product inside the capsule 2.

In General, the outlet openings 30, preferably distributed essentially over the entire surface of the lid or foil 40, at least essentially the entire surface of the holes specified were passing and the rim 38. This ensures uniform draining of the beverage from the extracted product inside the capsule 2.

In the examples in Fig.2, 3A-3d, the inlet 24 and outlet openings 30 have a circular cross-section. Holes 24, 30 with a circular cross section are easily bursting discs. Additionally, the cross section of the inlet holes 24 decreases (becomes thin towards the inner space 20. This provides the advantage that the input holes act as nozzles to cause a stream of fluid to enter the internal space 20.

It should be understood that the inlet 24 and/or outlet openings 30 can also have alternative forms. Holes 24, 30 may, for example, take the form of elongated slots. Preferably, the small size of the slits is small enough to hold the extracted product inside the capsule 2.

In a specific embodiment, the slit may have a shape that forms a tongue in the plane of the bottom. In this case, cracks may be essentially U-shaped, for example, semi-circular, u-shape, rectangular or V-shaped. This has the advantage that the tongue may be bent from the plane of the lower part under the action of the fluid flow through the CTE is rsta, setting tab. Thus, it is possible to achieve a larger volume of fluid flow. If the lower part is made of elastic material, the tongue will be turned back to the plane of the bottom, as soon as the fluid flow will cease, thereby preventing the displacement of the extracted product (before and) after preparation of the beverage. It should be understood that the slits that define the pull-tab can be applied to the lid, making the necessary changes.

As follows from the above embodiments, the capsule 2, 102, preferably, contains an annular first wall 10, 110, a second wall 12, 112, closing the ring the first wall at the first end, and a third wall 16, 116, closing the ring the first wall to the second, open end, an opposite second wall, the first, second and third walls enclose an inner space containing the ingredients for the drink.

In accordance with an additional embodiment (with additional option exercise can be an additional improvement of the above-mentioned variant implementation, for example, option, the exercise of any of figs.1, 2, 3a, 3b, 3c, 3d) capsule 2, 102 contains a sealing element to effect a seal between the capsule 2, 102 and the device 104 to prepare the drink. To this end, predpochtitelno, the present invention provides at least one of the first, second and third walls, essentially, to be made to work as a sealing element. Thus, it can be made very durable capsule is an effective, cost-effective way. In addition, the use of the individual (e.g., hollow) of the sealing element can be excluded.

In an additional embodiment, the sealing effect can ensure that during operation (when the device delivers the fluid under pressure to the extractable product in the capsule for preparing drinks) for only the flow of water, in fact, takes place through the interior of the capsule. The sealing effect can be achieved between the ring element and the holder of the capsule, as in EP1700548, but this is not necessary.

Wall, acting as a sealing element, can be performed in various ways. Some preferred non-limiting examples of the invention shown in Fig.4-9, which will be explained in more detail below.

For example, only the first wall, second wall, or only the third wall, essentially, can be designed in such a way as to ensure the sealing element. Alternatively, a combination of the first, second and/or third article is a NOC may be made in this way, to work as a sealing element. For example, in accordance with the embodiment, at least two of the first, second and third walls can be made as one whole and also work as a sealing element.

In the first preferred example, at least one of the first, second and third walls, essentially, may be of such dimensions to work as a sealing element. For example, one or more walls of the capsule may be of such dimensions to grapple with the seal with one or more opposing walls of the device, when the capsule 2, 102 is held in position in the receiver device.

Good results can be obtained when the capsule contains a hollow sealing element and, for example, a one-piece sealing element. Thus, it can be obtained more reliable and durable configuration.

Also, the wall, which is designed to work as a sealing element may have an outer surface, at least part of the surfaces of which are made to ensure the seal coupling with a covering element device 104 to make the drink while working.

Preferably, the sealing element is designed as a single unit according to stuudy wall of the capsule, for example, on the same production stage. Also, preferably, the wall, which is designed to work as a sealing element may be an elastic wall, for example, a wall consisting of an elastic material or an elastic material such as rubber, or elastic-plastic material.

Moreover, in accordance with the embodiment of the wall, which is designed to work as a sealing element of an elastic interface, at least one of the covering element device 1 for preparation of a drink holder capsules for achieving the sealing effect during operation. Alternatively, the wall, which is designed to work as a sealing element is plastically deformed during the interaction, at least one of the covering element of the device for preparation of a drink holder capsules for achieving the sealing effect during operation.

For example, the capsule in accordance with the invention can be part of a system for preparing a predetermined quantity of beverage suitable for consumption using an extractable product, the system also includes a device 104 that contains a device for filling a fluid environment is s for supplying a quantity of fluid, such as water, under pressure, or pressure, rising to a pressure of at least six bar, exchangeable capsule, and a receiver for holding the exchangeable capsule.

The use of capsules may include a method of preparing a predetermined quantity of beverage suitable for consumption using an extractable product, the method at least includes: location (shift) capsules with a wall in conformance with the supporting surface of the receiver 106 of the device 104 and the wall of the capsule, preferably, operates as a sealing element for achieving impervious to the fluid seal between the capsule and the device 104 to prepare the drink.

The first non-limiting example

In Fig.4A shows the capsule 202 in accordance with an additional embodiment of the invention. For example, the capsule 202 may represent an alternative to the capsule shown in Fig.1. Capsule 202 in Fig.4 includes an annular wall 210 and the bottom portion 212, which is preferably made as one whole with each other. In addition, the example includes the cover 216. Preferably, the capsule 202 has a symmetric shape of the rotation.

For example, the capsule can be designed so that the cover 216 may pierce through these means 128 d is I the lid 104. Alternatively, the cover 204 may be performed in such a way as not to pierce through these means 128 for cover during operation, for example, a cap, similar or equal to the caps of the capsules shown in Fig.2, 3A-3d. Also, the capsule 202 may be performed in such a way that its lower part 212 pierced through these means 122 for the lower part during operation. As an example, the lower portion 216 of the capsule shown in Fig.4, can be made the same as the lower part 16 of the capsule, as shown in Fig.1, or, alternatively, as the lower part 16 of the capsule shown in any of Fig.2, 3A-3d.

In the embodiment of Fig.4, preferably, as the annular wall 210 and the bottom portion 212 is made of flexible, elastic material such as rubber or rubber-like plastic. In particular, the capsule 202 variant implementation of Fig.4 differs from the capsule shown in Fig.1, so that the annular first wall 210, in essence, is designed to work as a sealing element. For example, the wall 210 may be designed to function as a sealing element, and can elastically interact, at least one of the covering element 106 and the holder 190 capsules device 1 for the beverage to achieve the playing technique of the seal during operation.

For example, as indicated in Fig.4b, the operation of the capsule 202 may include deformation of the annular wall 210, in particular, in such a way that walls work as a seal with respect to the receiver 106 of the device 101. For example, the annular wall 210 can cuddle or be bent outward to strong coupling with the receiver 106 in such a way that the trajectory of the flow of fluid between the capsule 202 and receiver 106 can be completely locked.

The elastic deformation of the parts of the capsule 202 may be achieved in various ways, for example by mechanical interaction between the capsule 202 and device 104, through the hydrostatic pressure of the fluid supplied to the receiver and the capsule during operation, or both.

For example, in accordance with one optional embodiment, the outward deformation of the wall 210 of the capsule can be achieved by means of pressure exerted on the capsule device 101, as of the closing of the receiver 106, that is, by moving the holder 190 capsules and receiver 106 in direction to each other (in the state of retention of the capsule). For example, the capsule 202 may be of such dimensions to shrink (in axial direction) by the receiver 106 when the capsule 202 is held between the holder 190 and the receiver 106 (and the holder 190 and the receiver 106 has been moved towards each other, in the state of retention of the capsule). In Fig.4a arrow R schematically indicate the force applied by the device 104 (e.g., while moving towards each other receiver 106 and the holder 190), acting on the capsule to provide axial compression of the capsule 202.

As shown in Fig.4a, 4b, compression capsules may cause bending outward of the annular wall 210 (indicated by arrows Q and axial movement with the cap 216 and the lower part 212. For example, compression may cause deformation of the annular wall 210 (for example, essentially of a conical shape) in a more curvilinear shape (when viewed in longitudinal section), for example, more than a hemispherical shape or a paraboloid of revolution. Also, compression can lead to grip the outer surface of the annular wall 210 at least partially to the inner surface of the receiver 106.

In addition, the bending elastic walls of the capsules can be achieved through these means 108 to the lower part, which can pierce the bottom portion 212 of the capsule 202 during operation. For example, these means 108 to the lower part can contribute to the above-mentioned deformation of the outside annular wall through the clutch (and the displacement or deformation) with the bottom part 212 capsules during operation. As an example, for this purpose, the lower part of the cap 212 is uly can be made in this way, to interact with these means 108 to the bottom, using the friction to move in the axial direction inside (in the direction opposite to the lid 216) for a certain (relatively small) distance. In yet another additional embodiment, the deformation of the annular wall 210 to achieve the sealing effect can be completely based on the interaction between these means for the lower part of the capsule.

In accordance with the embodiment, during operation of the capsule 202 are made so as to be compressed so that the compression leads to the reduction of the internal volume of the capsule 202. The reduction can lead to compression of the contents of the capsule (i.e., the extracted product), leading to the extracted beverage having improved strong taste and structure.

Also, in accordance with an alternative embodiment of the capsule 202 are made so as to be compressed so that the compression leads to an increase in internal volume of the capsule 202. For example, the increase may lead to saturation of the air content of the capsule (i.e., the extracted product) during operation, which can lead to the extracted drink that has a more delicate taste and, for example, a different structure than the structure, which can be obtained using siteproduct.

In yet another embodiment, the capsule 202 may be designed in such a way as to be compressed during operation, the compression essentially does not change the volume of the inner part 220 capsules. Still, in this case, for example, the external volume of the capsule 202 may change as a result of compression to achieve the desired sealing effect with the device 104. In a non-limiting example, the contents of the capsule 202 may prevent the compression so that the inner part 220 capsules, essentially, does not change the volume when the capsule 202 (in particular, the outer part of the capsule 202) deformed. As an example, this can be achieved through the capsule, which is completely filled with compressed extractable product, such as compressed roasted and freshly ground coffee.

Also, deformation of the sealing wall of the capsule (in this example, which is the annular wall 210 may be partially or entirely the result of hydrostatic pressure (schematically indicated by arrows H in Fig.4a). As an example, the fluid which is fed into the capsule under pressure may deform the flexible annular wall 210 to the outside (see arrow Q), leading to the desired sealing effect (with the inner surface of the receiver).

As an alternative example of Fig.4, only the annular wall 210 capsules are made is of flexible resilient material, moreover, the bottom portion 212 of the capsule may have a different configuration (for example, rigid configuration). For example, the bottom portion 212 of the capsule 202 may be made of a different material than the material of the elastic annular wall 210.

A second non-limiting example

In Fig.5 shows another variant of implementation 302 of the invention. An implementation option 302 in accordance with Fig.5 may include all or some of the elements of option implementation 202 in accordance with Fig.4.

Also, the capsule 302 in accordance with the second embodiment can provide an alternative to the capsule shown in Fig.1. Capsule 302 in Fig.5 includes an annular wall 310 and the lower portion 312. In addition, the example includes the cover 316. Moreover, as an example, the lower portion 316 of the capsule 302 shown in Fig.5, can be made the same as the lower part 16 of the capsule, as shown in Fig.1.

As in the above embodiments, implementation, this capsule 302 may be designed so that the cover 316 can pierce through these means 128 for the lid 104. However, preferably, the cover 316 is designed in such a way as not to pierce through these means 128 for cover during operation. As follows from the drawing, preferably, the cover 316 provides an output f is ltr and includes many of the outlet openings or pores 330.

In the example of Fig.5, preferably, the cover is designed to work as a sealing element. To this end, in particular, the cover 316 includes an appropriate passing outside rim (flange) 338, preferably made as one whole with lid 316. This sealing rim 338 is designed in such a way that, at least, to be deformed, essentially, in a normal direction relative to the outer surface of the cover 316 capsules.

In accordance with an additional embodiment, the cover 316 (and the corresponding sealing rim 338) represents the elastic wall, for example, made of an elastic material such as rubber, or elastic-plastic material. Also, as shown in Fig.5, the sealing rim 338 is a solid part of the cover 316 (i.e., the sealing rim 338 does not contain holes of the filter). Preferably, the rim 338 (working as a sealing element is a solid, one-piece sealing ring, for example, solid flat sealing flange. In this embodiment, the rim 338 includes parallel outer annular surface, passing radially relative to the Central line of the capsule 302.

For example, is designed as one whole square is Skye rim 316 may be implemented in such a way to be compressed between the ring part) by the receiver 106 and the holder 190 capsules while working to ensure the locking of the trajectories of the flow of fluid between the receiver and the capsule.

In accordance with the embodiment, the cover 316 preferably designed in such a way as not to tear and/or break during operation (i.e., when fluid under pressure is fed into the capsule). In addition, it is possible to cover 316 is deformed outward during operation under acting on it by the pressure of the fluid. For example, the outward deformation of the cover 316 may lead to an increase of the outlet openings 330. Preferably, the outlet port 330 is designed so that each hole 330 (or time) can hold the extractable product, such as ground coffee inside the capsule 302, when the corresponding cover 316 is deformed by the pressure of the fluid medium during operation.

A third non-limiting example

In Fig.6 shows a third non-limiting example of a capsule 402. In this example, the lower portion 412 of the capsule 402 is designed to work as a sealing element to effect a seal between the capsule and the device 104 to prepare the drink. This capsule also contains an annular wall 410 and the cover 416, which may provide the account for the output filter 436 (e.g., having outlet openings 430).

An implementation option, shown in Fig.6, different from the version of the implementation shown in Fig.4, so that the lower part 412 is designed in such a way as not to pierce through these means to the lower part (device for filling) 108 device 104. To this end the lower part 412 (which closes the annular first wall 410 on the first end has a partially hollow configuration.

In particular, the lower portion 412 includes a first part 412U the lower part and the second part 412L lower part that encloses the region A, V placement of the fluid. The area of the fluid has a first section A, which is the (Central) hole A, to host device 108 for filling when it is in its extended position. The second part V layout area of the fluid made with the possibility of distribution of the fluid accepted from the device 108 for filling, the second part 412U the bottom. The second part of the 412L the lower part serves as an input filter for supplying a fluid medium into the interior 420 of the capsule 402. For example, the configuration of the second part 412U the bottom, essentially, may be the same as or similar to the configuration of the lower part 12 of the capsule of the embodiments of Fig.3a, 3b, 3c or 3d, or she may have another proc is the tenant.

Preferably, at least the first (outer) part 412U lower portion 412 of the capsule is designed to work as a sealing member and to elastically interact with the covering element of the device for the beverage to achieve the effect of the seal during operation. For example, the first part 412U the lower part may consist of a flexible, preferably elastic material, such as rubber, or elastic-plastic material. As an example, the first part 412U the lower part can be dimensioned in such a way to shrink (in axial direction) by the receiver 106 when the capsule 202 is held between the holder 190 and the receiver 106 (and the holder 190 and the receiver 106 has been moved towards each other in the state of retention of the capsule).

The fourth non-limiting example

In Fig.7 shows a fourth preferred example of the capsule 502, which can provide a reliable seal during operation and improved prepared at relatively low cost. An implementation option, shown in Fig.7, is similar to the example shown in Fig.3A, but at least different from the example that the capsule 502 includes a lid 516, working as a sealing element (through appropriate made in the form of odnoglazogo part 538 rims). For example, a cap 516 may be performed the same as or similar to the cover 316 of the second example shown in Fig.5. In the example of Fig.7, the capsule is provided with a lower part 12, which is not pierced by the device 108 for filling during operation, leading to the aforementioned advantages. As the cover 516 and the lower part 12 can be made many different ways, some of which were further explained above.

The fifth non-limiting example

In Fig.8 shows another example of the capsule 602. An implementation option, shown in Fig.8, is similar to the example shown in Fig.3d, but at least different from the example that the capsule 602 includes an annular wall 610, working as a sealing element (through appropriate made in the form of a single, annular, continuous sealing part 638). In the sixth embodiment, the sealing element 638 annular wall 610 protrudes from the corresponding wall (for example, in the radial direction). In particular, the sealing element 638 and the corresponding wall 610 capsules can be designed to deform, at the same time, for example, under the action of external pressure applied by the receiver device 106 to the sealing element.

p> For example, coming out of the sealing portion 638 and the annular wall 610 can be made as one whole, of the same material, for example elastic material, more specifically, of rubber or rubber-like (plastic) material. As follows from Fig.8, for example, coming out of the sealing portion 638 is located at a distance from the axial end parts of the circular wall 610. For example, the sealing portion 638 may be located in or near the axial center of the annular wall 610. In an alternative embodiment, the sealing portion 638 of the ring wall 610 is located at or near the bottom of the capsule.

The sixth non-limiting example

In Fig.9 shows a sixth example of the capsule 702. This example provides an alternative option to the implementation shown in Fig.6. As shown in Fig.6, the capsule case for 702 in Fig.9 is provided with the bottom part 712, which is designed to work as a sealing element to effect a seal between the capsule and the device 104 to prepare the drink. This capsule also contains an annular wall 710 and the cover 716, which can provide an output filter 736.

The lower portion 712 variant implementation, shown in Fig.9 (which closes the annular first wall 710 on the first of the end) has a partially hollow configuration.

In particular, the lower portion 712 includes a first part 612U the lower part and the second part 712L lower part that encloses the region A placement of fluid from the annular part A the bottom. For example, the portion of the annular wall 710 may provide annular part A hollow lower portion 712.

Region A placement of the fluid lower portion 712 capsules can host device 108 for filling, when this device is in its extended position. Region A placing the fluid can also distribute the fluid, adopted from the device 108 for filling, the second part 712U the bottom. As in the example of Fig.6, the second part 712L the lower part serves as an input filter for supplying a fluid medium in the space 720, which contains the extracted product.

In the embodiment of Fig.9, preferably, at least the first (outer) part of the 712U lower portion 712 capsules can function as a sealing element by coupling with seal covering element of the device for preparing a beverage while working. For example, the first part of the 712U the lower part may consist of a flexible, preferably elastic material, such as rubber, or elastic-plastic material. As shown in Fig.9 by arrows G, the elastic is art 712U can snuggle up to the outside (at least in the radial direction) through the fluid supplied under pressure into the lower portion 712 (corresponding to the hydrostatic pressure is schematically shown by arrows H in Fig.9).

In this example, the hollow lower portion 712 includes a blocking fluid flow design to prevent or inhibit leakage of fluid from the lower part of the capsule in the receiver device 106. For example, the locking structure may include a conical or cylindrical sleeve 788 passing from the first (outer) part of the 712U the lower part of the second (inner) part 712L the bottom. Preferably, the blocking design 788 shall be of such size to accommodate the above-mentioned device 108 to dispense fluid with a relatively small gap or no gap. Radialnaya surface of the sleeve 788 and the inner surface of the element A annular wall may include a region that hosts the fluid under pressure is supplied to the lower part) during operation. The resulting pressure of the fluid may be drawn by the sleeve 788 and element A annular wall to move away from each other (in radial direction), preferably, causing the thrust element A annular wall to the inner surface of the device 104 and, preferably, also leading to pinning the sleeve 788 (in the Rog) device 108 to dispense the fluid. Thus, there may be obtained an improved sealing effect.

The seventh non-limiting example

In Fig.10 shows another variant implementation 802 of the invention. For example, an implementation option 802 in accordance with Fig.10 may include all or some of the elements of option implementation 302 in accordance with Fig.5. Also, the capsule 802 in accordance with the seventh embodiment can provide an alternative to the capsule shown in Fig.1.

In particular, the capsule 802 in Fig.10 includes an annular wall 810 and the lower part 812. In addition, the example includes the cover 816. In the example of Fig.10, preferably, passing on the outside (circle) rim (flange) 838 is provided in such a way as to function as a sealing element. If you want the hem 838 can be made as one whole with lid 816. Preferably, the hem 838 made in the form of a single annular wall 810. Preferably, the hem 838 made of the same material as the annular wall 810.

This border 838 capsule is provided with a relatively thick section A (ledge), for example, which is thicker (if measured in the normal direction N with respect to the outer surface of the cover 816 capsules) than the adjacent part V edges. In this example, the protruding portion ark near the edge of the ring wall 810, in this second part V edges (having a smaller thickness than the thickness of the protruding part of the border) runs around the protruding part A. Alternatively, the protruding portion A may be located at a distance in the radial direction from the edge of the ring wall 810. The radial width of the protruding part A may be approximately the same as the radial width of the rest of V edges, or it can be smaller or larger than the radial width (for example, more or less in the range from about 1 to 99%).

The thickness of the protruding part A is constant in this example. For example, the thickness of the protruding part A (measured in the specified normal direction N) can be 0.1 mm longer, or more than the thickness of the second part V edges (measured in the same direction N). Additional non-limiting embodiment, the difference between the two thicknesses (i.e., parts A and B) may be in the range of 0.1-1 mm

In an additional example, prior to use, the thickness of the second part V edges may be approximately 0,2 mm In this case, preferably, the thickness of the protruding part A less than 0.5 mm, more preferably less than 0,41 mm, for example, less than 0,35 mm

Thus, in the embodiment, the capsule shown in Fig.10, may contain one, essentially, the concentration of the systematic annular ledge A, passing on the outside of the Cup. In an additional embodiment, the protrusion A can be made of the same material as the annular wall 810.

This sealing part E edges can be performed so that at least deformed, essentially, in a normal direction relative to the outer surface of the cover 816 capsules. In accordance with an additional embodiment all of the sealing rim 838 represents the elastic part, for example, made of an elastic material such as rubber, or elastic-plastic material. In another embodiment, the sealing rim 838 is a non-resilient deformable part, for example made of a plastic deformable material, a compressible while working to achieve the sealing effect. Preferably, the hem 838 (working as a sealing element is a solid, one-piece sealing ring, for example, solid flat sealing flange.

Also, for example, the protruding portion A can be designed in such a way as to be compressed between the ring part) by the receiver 106 and the holder 190 capsules while working to ensure the locking of the trajectories of the flow of fluid between the receiver and the capsule.

In Fig.10 ve is hnie surfaces of the two parts A, V edges (surface facing the outer surface of the cover 816) parallel relative to each other and with the outer surface of the cover, however, this is not essential. For example, in an alternative embodiment, the protruding portion A may be provided with an upper surface which has a curved shape (when viewed in longitudinal section), or surface, which includes an angle in the range of about 10-80 degrees, for example, 30-60 degrees, with the top surface of the other part V edges (as viewed in longitudinal section).

There are different modifications of the capsule 802, as shown in Fig.10. For example, the capsule may be provided with a projecting part, which is located at a distance from the first protruding part, the deeper part of the border lies between them. Also, in an alternative embodiment, the capsule may be provided with a projecting part, which runs along the outer perimeter edges.

Illustrative embodiments of described above provide significant improvement versus capsules of the prior art and related systems for the beverage. Since at least one of the first, second and third walls, essentially, is designed to work as will condense the high element, you do not need to provide capsules with a special hollow sealing element. In addition, embodiments of capsules in accordance with the invention can be manufactured very efficiently using a relatively small amount of energy and materials. Also, certain embodiments of provide compressible or otherwise deforming the wall of the capsule acting as a sealing wall, which can improve the process of cooking drink. For example, relatively good results can be achieved if the sealing element is a solid annular element, which is an inseparable part of the wall of the capsule.

In the foregoing description the invention has been described with reference to specific examples of embodiments of the invention. However, it will be apparent that various modifications and changes can be made here, without departing from the broader idea and scope of the invention as defined in the attached claims.

In the claims, any reference positions in the parentheses should not be interpreted as limiting the claims. The word "comprising" does not exclude the presence of other signs or stages in addition to those outlined in the claims. Moreover, the unity of the Noah should not be construed as limited to "only one", and instead is used to indicate "at least one" and does not exclude many. Statement of the specific characteristics in different claims does not exclude the possibility of a profitable combination of these features.

Also, for example, different parts of the capsule can be made of different materials. In an alternative embodiment, the wall or part of wall acting as a sealing element may be made of elastic material such as rubber, or elastic-plastic material. Wall, acting as a sealing element, can also be performed, for example, of metal, for example, one or more layers of metal foil.
