The invention relates to the extraction system for preparing a beverage, such as coffee containing capsule used in an adapted for this device.

The system containing the device in which the capsules are used, known, for example, from document WO 205/004683. In this system, the capsule is inserted into the device between the two parts of the camera module extraction. The capsule is placed in the guide means, in particular, in two guides, the receiving flange of the capsule, and the capsule is mounted in an intermediate position in contact with the retaining means, in particular, the protrusions arranged in the guide rails. Then the capsule is covered by at least one part of the camera ("cavity injection"), which linearly moves in the direction of another part of the camera ("extraction plate"), causing the capsule to sink leading to deformation of the flange and forces the capsule to pass down the retaining means (projections). The capsule is in the extraction position and closes the two parts of the chamber.

In document WO 2009/043630 using the same principle. However, the movable part of the camera is connected to the guide means, which moves the capsule in the direction of another part of the chamber and its passage through the retaining means (projections).

According to this document�, when you re-open the device for at least one of the parts of the cell are given back; as a result, the capsule is no longer supported retaining means (projections), forcing her to fall under its own weight in the tray to collect capsules.

This raises the problem, consisting in the fact that the surface extraction may stick to the extraction plate. This can occur, in particular, in cases where the capsule for a long time left in the device in the closed position. This problem can have serious consequences, for example, solidification of the residue liquid on the surface, repeat the softening and adhesion of the surface material of the capsule, mechanical curvature of the surface on the protrusions of the extraction plate, etc. When this problem occurs, the capsule can no longer be pushed out naturally when the device is re-opened (when one of the parts of the cell are given back). In this case it is necessary to push the capsule through the housing manually or mechanically. The capsule can also be in the device is stationary and to prevent or delay the use of the system with another capsule.

The object of the invention is a solution to this problem by improving the known systems and developing simple solutions that will improve over�l the removal of the capsule.

The present invention relates to a system for the preparation of beverages using capsules according to the claims.

In particular, the invention relates to a system for preparing a beverage from a capsule containing a portion of ingredients, including:

- capsule with the ingredients, which comprises a housing in the form of a truncated cone with the surface of the injection and surface extraction with a hole on the wider side and ending in a flange, and a portion for supplying beverage covering, at least partially, the opening in the housing; wherein the flange has a portion of the base coupled to the housing, and terminates in a free edge, preferably forming roller, and includes a seal attached to the flange or integrally formed with it and additionally passing partly along a side wall of the housing; wherein the seal means is preferably convex or has an increased thickness compared with the rest of the flange;

device for preparing beverages comprising: a housing; guide means for introducing a capsule into the device, in particular, through its flange; the first part of the chamber containing the cavity, the shape of which is essentially adapted for grasping of the capsule housing, the means of injection well�dcosta and the clamping surface, which engages with a means of sealing flange; the second part of the chamber containing an extraction plate, preferably having a hole for discharging the beverage passing through the portion of the feed side surface extraction; wherein at least one of the two parts of the chamber is arranged to move relative to another part of the chamber from an open position in which the capsule is inserted in a closed position in which the capsule is locked between the two parts of the chamber.

According to the invention the first portion of the chamber contains a means for capturing the capsule that allows you to hold it in said first cavity of the camera during movement from the closed position to the open position, wherein the capsule contains a response means adapted to capture breathtaking means.

This eliminates the risk of accidental delay of the capsule in the extraction plate, because the capsule is retained in the first part of the exciting camera means. When you reopen the capsule device is securely held in place in part of the cell that is at least sufficient to separate the capsule from the extraction plate.

The device according to the invention also contains means to release the capsule, which affect the CAPSA�and/or exciting means to release the capsule from the first camera, the capsule could then fall under its own weight. Preferably, the releasing means act on the flange of the capsule and are a focus for him during the relative movement of the parts of the camera when the device is opened, thereby facilitating ejection of the capsule from the cavity of the first part of the chamber.

The capsule is adapted to the device and, in large measure, to the exciting means. This capsule has a free edge, which preferably contains a plot in the form of a roller, forming at least one of the response tools that can be captured in the exciting means. In this case, the exciting means is preferably formed by a single capture. This grip is preferably located on an outer edge of the first part of the camera. He can speak on the clamping edge of the specified first part of the chamber for grasping the flange of the capsule is preferably specified portions in the form of a roller, which radially protrudes from the clamping edge.

Preferably, the roller on the free edge of the flange forms an essentially toroidal region with a diameter providing its placement in at least two seizures. Preferably, the grippers are arranged at an angle some distance on both sides of the outer edge of the first part of the camera. Angular displacement p� least two grippers provides a more secure grip of the flange of the capsule. Preferably exciting means comprise at least two diametrically opposite clamping or three capture, distributed around the circumference of the outer edge of the camera. Each gripper is resiliently deformable and is opened under the action of pressure of the capsule, for example, its flange in contact with the capture and re-closes as soon as the capsule is positioned in the cavity of the camera. In particular, the capture contains the main part which can be bent outward during the exit roller flange.

Capsule is kept exciting means, in particular above the grips. To this end, the diameter of the flange is essentially equal to the distance between the inner recesses of these grips, but slightly exceeds the maximum distance between their sloping sites. The maximum diameter (D) of the flange is approximately 37 mm, and maximum thickness (w) of from about 0.5 to 2 mm.

To improve the grip of the capsule and there are other exciting tools: exciting means comprise at least one protruding rib, passing into the cavity from its inner surface to form the portion of the cavity in the form of a narrowed opening. Capsule on the surface of the body includes a wall section in the form of a truncated cone, which forms another part of the mentioned response among�PTS for deformation without fracture upon contact with the specified protruding rib. A wall section of the capsule in the form of a truncated cone preferably forms a section, whose cross section is slightly larger cross-section of the hole of the cavity, bounded by the specified at least one edge, so that this portion can be deformed without fracture during insertion of the capsule into the cavity. During insertion of the capsule portion of its wall deformed without breaking at least two ribs that are angled at a certain distance from each other and protrude from the inner surface of the cavity, or a continuous rib which runs along the circumference of the cavity.

A wall section of the housing of the capsule in the form of a truncated cone is preferably made of a deformable material, such as aluminum, plastics or material based on starch. Preferably, the entire housing is made from the same material. However, in this phase may be provided for reinforcement or more flexible and/or replacement of the material to improve the deformation of the above-mentioned land without breaking.

A wall section of the capsule in the form of a truncated cone preferably has a thickness mainly from 0.1 to 1 mm, preferably from 0.2 to 0.7 mm.

Outside edges of the cavity of the camera has essentially the shape of a truncated cone, vorp�Stateline corresponding to the form of a capsule, but essentially wider. In particular, the size of the capsule housing allow him to form a gap between its surface and the clamping area of the specified first part of the chamber from the bearing surface of the flange. Presser plot also contains grooves that pass radially and/or inside the cavity. These grooves are filled with a deformable seal means through its compression at least at a peripheral line for receiving the seal between the capsule and the first part of the chamber during the closing of the first and second parts of the camera around the capsule, and/or when the seal comes into contact with the injected fluid.

A seal means, for example, may be formed convex ring, attached to a supporting body portion of the capsule or integrally formed with it. It can be made of a material such as silicone, rubber, cellulose, modified starch, or any combination of these materials.

Another aspect of the invention is the orientation of the extraction plate in this position, to reduce the risk of freezing, as described in application EP 10290148.5. To this end, the surface of the extraction plate is provided with a group of several rows of convex elements, bounding several rows of channels, and provides tools for its installation in the housing or in part. The funds of the mouth�unit configured for positioning the said plate to guide the plate thus the said channels being inclined relative to the horizontal plane at an angle more than 15°, preferably approximately 45±10°.

As shown in Fig.1, the system according to the invention comprises a capsule 1 which is used in the device 2 for preparing short�Oia beverages (shown partially).

The capsule comprises a housing 3 in the form of a truncated cone. The housing has a first side surface 4 of the injection, which, as a rule, is closed and can perforirovanie or may have holes that allow water to pass through the capsule. The body of the capsule ends from the second side flange 5, which acts radially outwards of the housing around the entire circumference of its wider base. On this side surface extraction the body comprises a hole covered, at least partially, a part to feed or wall 6. The flange includes a portion 7 of the base and the free edge 8 is preferably in the form of a roller. The flange includes a sealing means 9, which is attached to the portion 7 of the base or embedded in it. The seal means may be a compressible material. It can also soften upon contact with the liquid is supplied under pressure during extraction. These compression and softening can be combined to obtain a sealed connection.

Capsule contains the ingredients to make the drink. In particular, the ingredients can be ground or instant coffee, tea, cocoa, dry milk, and any possible combination of these ingredients.

It should be noted that the size and shape of the capsule is adapted for placement in the arrangement and formation of an interconnected system that can easily and effectively be used.

For its part, the device for preparing drinks contains guide means in the form of two guide rails 10 arranged on both sides of the capsule at a distance from each other and providing a direction of the flange 5 of the capsule (Fig.1 shows only one guide 10). Thus, this guiding tool allows you to insert the capsule into the slot 11 of the housing 12 of the device. As shown in Fig.1, the capsule is held in an intermediate position retaining means 13, in particular, the protrusions arranged in the guide rails at a height such that the capsule was maintained above the longitudinal axis of the extraction, which will be explained below.

The device comprises a first part 14 of the chamber and the second part 15 of the camera, limiting the seat 11. These parts 14 and 15 can move in a direction toward each other for locking the capsule. It should be noted that the mobile can either be only one part of the camera when stationary the other, or both parts can be movable. In the illustrated embodiment, the first portion 14 of the camera is rolling, and the second part 15 of the camera is stationary, but can be and Vice versa, as described in document WO 2009/043630.

In the example shown the first part of the camera 14 includes a cavity 16, the shape of which essentially corresponds to the shape of the housing of the capsule, i.e. the cavity is in fact also has the shape of a truncated cone and extends in the direction of her holes so in this cavity can accommodate a capsule when closing the device. Part 14 of the camera includes means 17 of the injection fluid (hot water under pressure), containing, for example, the inlet channel 18 for liquid, means 19 perforating the surface of the injection capsule 1, for example, blades, and a check valve 20. Part of the chamber may be formed of several parts, as shown in the drawings: of the main part 21, and is inserted in the piston part 22. The piston portion is moved back during its contiguity to the flange of the capsule due to the hydraulic thrust of the fluid that acts on the piston portion in the axial direction of the closing, as described in document EP 2068684. Part 14 of the chamber, in particular, its piston part 22 contains the front clamping surface 23, which is designed to compress the sealing means 9 of the capsule to create an airtight or hermetic contact with the fluid under pressure. During the pressing or pressure seal means is compressed to compensate for the irregularities of the pressure surface 23. As described in document EP 2068684, the clamping surface 23 of the first chamber preferably contains a groove, passing at least radially on both sides of the front clamping surface.

The device also contains Executive fur�mechanism 24 for bringing together parts of the camera in particular, in the example shown, to move the first part. Can be used by any mechanism, such as lever that can be actuated by a lever (not shown) or a Cam or screw mechanism.

The second part 15 of the camera contains an extraction plate 25 having an outlet 26 for discharging the beverage. In addition, the plate may contain convex elements 27 that allows the input side (for example, aluminum or plastic membrane) to open under the action of internal pressure created in the capsule. This principle is described in document EP 0512470 B1. Extraction plate 25 can be placed in the seat in the front part 28 of the device. The front portion can also contain a camera collection 29, terminating in a pipe 30 for supplying the drink. It should also be noted that one of the possible variants of the extraction wall is installed in the movable part of the second part of the chamber.

Fig.2 shows the closed device in locking position of the capsule. For this first part of the camera via an actuating mechanism 24 is essentially linearly moves in the direction of the second part 15 of the camera. The first part 14 of the camera during the move, heading for translational movement along the guide means, containing, among other things, two grooves 31,�made in the housing, in which there are two side guides of the ribs or protrusions 50, 51 (Fig.4) in part 14. It should be noted that the movement of the camera in the housing need not be strictly linear, but may also combine horizontal and directional movement (e.g., by using an inclined section) depending on the specific shape of the guide grooves 31.

As described in document WO 2005/004683, it is essential that the first part 14 of the camera covers the capsule 1 during its movement in the direction to the second part 15 of the camera and puts her effort to lower the capsule from the intermediate position (Fig.1) in the extraction position (Fig.3). For this, the capsule is held in an intermediate position (Fig.1) (in an inclined position due to its asymmetrical shape and because of the shift of its center of gravity relative to the flange) above the X-axis representing the axis of the extraction, when the capsule is locked (Fig.3). Axis extraction is the middle line of the capsule or cavity 16 and passes through the center of the extraction wall when the device is closed. The capture of the capsule is performed using the cavity 16 of the first part, covering the body 3 of the capsule and applies the force to lower the capsule and its installation along the X-axis extraction. When the capsule is lowered, the flange of the capsule is deformed for passage of the retaining means (exhibition�CEM). It should also be noted that the movement is relative, and what may be movable second part that moves the capsule in the direction of the first fixed part. It should also be noted that the retaining means can be elastically deformable.

During the move the closure (Fig.2 and 3) part 14 of the chamber in contact with the flange of the capsule due to the pressing, squeezing the flange at the peripheral surface of the extraction plate 25. Between the cavity 16 and the surface of the capsule housing is formed a gap. However, during the extraction, the fluid cannot flow along the pressure surface 23 due to the presence of means for sealing the capsule, which at least partially fills cavities (grooves) above the surface. Thus, fluid can pass through the capsule (and layer ingredients) from the means 20 of the injection and outlet openings located in an extraction plate 25.

According to one embodiments of the invention shown in Fig.4, during the closing of the capsule device 1 communicates with the device 2 and is captured in the cavity 16 of the first part 14 of the chamber, where it is held by spectacular means during the closure in the position shown in Fig.3. Exciting means comprise at least one gripper 32, which supports the presser surface 2 in the direction outwards from it. The grip protrudes out of the cavity from the outer surface 33 of the first part chamber (piston portion 22). The free end 8 of the flange of the capsule is made in the form of a roller, which engages with a grip 32 by clamp in engagement during the closing device, i.e. due to the clamping force applied with the pressure edge 23 to the flange 5. Preferably there are several grips located on the outer surface of the cavity around the circumference at a distance from each other. For proper retention and prevent partial separation of the capsule and the cavity preferably has at least two grippers.

Flange dimensions 5 allow you to fully insert it into the grips: the maximum diameter D of the flange essentially exceeds the maximum distance d between the sloping portions 34 of the gripper, which allows him to engage in the recesses 35 of seizures. Flange thickness also allows you to insert it into the recess 35. The optimum diameter of the flange is approximately 37 mm, and its optimum thickness w of approximately 0.5 to 2 mm. Thickness w in this example is measured along the axis, i.e. perpendicular to the diameter. Inside the recess of the grip also has a sloping surface that allows you to release the flange by the application of force to the main part of the grip to bend outward when the flange finds�I am in a position of engagement with the supporting means, as will be explained below.

In the engaged position of the capsule in the exciting means or grippers 32 (Fig.4) the means 9 of the seal or the seal 9 is not enough compressed by the surface 23 to form a seal (i.e., to compensate for the material of seal surface irregularities, such as radial grooves), so it puts efforts, providing suction, or has no other impact, resulting in the release of the capsule could cause difficulty.

There may be other exciting means, for example, protruding ribs 38 extending from the inner surface of the cavity inside it. These ribs define a narrowed or reduced cavity section 16 applies force to the body of the capsule to its deformation in the inner direction, as shown in Fig.4. For this capsule in original condition has a wall 39 in the form of a truncated cone larger cross section, which is deformed without fracture under the action of pressure exerted by the ribs 38. When the capsule is placed in the cavity of the first part 14 of the chamber wall 39 of the capsule is deformed ribs, which are oriented slightly to the side surface 4 of the injection so as to hold the capsule is captured in the cavity.

There can be only one spectacular, means or grippers 32, or ribs 38.

When the device is opened upon completion of the extraction, as shown in Fig.5, the portion of the chamber disposed from each other. There are funds release capsules to extract it from the cavity under the action of the relative movement of those parts. In particular, when the first part 14 of the camera is moved back, it forces the flange of the capsule (which acts radially outwards from the side of the camera) to cling to the support surface 40 on the housing. The support surface 40 may contain several sections, which are sized and located so that they could enter into contact with the free edge or roller 8 of the flange. The body also has a lateral recess 44 for the passage of the grippers during the lock flange of the capsule.

As shown in Fig.5 and 6, further, the capsule is released from the exciting means and under its own weight can fall through the hole 41 in the housing.

Fig.8 and 9 shows in detail a piston portion 22 of the first part of the camera. It should be noted that the inner surface portion 22 (Fig.8) contains multiple edges 38A, 38b, -38 Celsius only, distributed over the periphery of the cavity and forming the retaining hole of the capsule. Also shows two grippers 32A, 32b, made of the same material and integrally formed with the piston part. Seizures may elastically deform, as he performed�s made of plastic and/or metal. It should be noted that the clamping surface 23 has several radial grooves 42, which are intended to cooperate in engagement with the seal means of the capsule. The grooves can pass into the cavity, forming grooves 43 more depth.

Of course, the invention can provide a variety of options for its implementation.
