The technical field to which the invention relates.

The invention relates to a capsule, system and method for preparing a predetermined quantity of beverage suitable for consumption using the extracted product.

Background of invention

Known systems for the beverage, for example coffee, using a cooking device for supplying liquid such as water, under pressure, the capsule containing a dose of the ingredient of the drink. Typically, the cooking device includes a receiver for receiving the capsules, for example covering element to accommodate the capsules. When used between the capsule and the covering element has a sealing engagement, in order to prevent leakage of liquid such as water or beverage. Sealing engagement is usually achieved by pressing the capsule and covering element to each other by a circumferential line of contact.

The material covering element at the location of the sealing engagement, for example, the elastomeric material may be softer than the material of the capsule at the location of the sealing engagement, for example, aluminum. Such a system is known, for example, from EP 1203554. In this case, the material of the covering element at the location of the sealing engagement may be compressed. Such systems can have is the disadvantage what material covering element at the location of the sealing engagement may be subject to wear and tear, destruction and/or contamination, so that with increasing age the cooking device as the sealing engagement may deteriorate.

This disadvantage seems to be overcome, at least partially, in other known systems, in which the material of the covering element at the location of the sealing engagement, for example metal, harder than the material of the capsule at the location of the sealing engagement, for example plastic. Such a system is known, for example from FR 2617389. In this case, the material of the capsule at the location of the sealing engagement may be compressed. Such systems have the advantage that the material of the covering element at the location of the sealing engagement may be less prone to wear and tear, destruction and/or contamination, can be provided with good sealing engagement. Especially convenient manufacture of the capsule when the capsule material at the location of the sealing engagement is the same material as the material of the circumferential wall. It may, however, have the disadvantage that the sealing engagement may be broken, if the covering element at the location of the sealing engagement of them is no roughness, for example scratches, cracks, caked dirt, the protruding parts and the like.

So from WO 2007/137974 known capsule having a seal acting on the edge. This seal is formed rolled edge formed on the outer border of the protruding edge of the capsule.

The invention

The objective of the invention is to eliminate, at least partially, one of the above disadvantages. In particular, the object of the invention is to provide a capsule for preparation of a given amount of beverage suitable for consumption using the extracted product intended for use in a device for preparing drinks containing the receiver to interact with the capsule, which has improved adhesion between the capsule and the receiver to prevent possible leaks due to unevenness of the receiver and/or capsules.

For this purpose according to the invention created a capsule for preparation of a given amount of beverage suitable for consumption using the extracted product, using the device for preparing beverages containing receiver for placing capsules containing a Cup containing a circumferential wall, a bottom closing the circumferential wall at the first end, and the cover, when using the connected with the Cup on vtoro the end of the circumferential wall, opposite the bottom, and the wall, bottom and lid when using the cover inner space containing the extractable product, and at least a portion of the surface of the capsule, designed using to communicate with the receiver has at least one projection for education sealing engagement with the receiver, which according to the invention is a textured material containing a modulated surface, which includes the set spaced at regular intervals of recesses and elevations, and the height difference of the recesses and elevations is at least 0.05 mm, preferably at least 0,15 mm

Found that by creating a local protrusions on the surface of the capsule in the area intended for interaction with the surface of the receiver, the surface roughness of the latter can be effectively compensated. It is clear that can be provided for different types of surface irregularities, including, but not limited to, local pickup local protrusions, cracks, breaks, local wear and so on, Respectively, at least one projection can be created on the surface of the capsule in the position in which have arisen or which may arise roughness. At least one projection may, for the example, to be created on the outer surface of the Cup. If the Cup contains planteary rim extending outside circumferential wall at a second end of the at least one projection may, for example, be created on lanzoprazol the rim. The receiver can be made in the form of a covering element, which can be, at least partially, to accommodate the capsule, and may, in use, to hug the rim of the capsule. Due to the fact that the receiver is typically made of extruded plastic, may be slight manufacturing defects. This can cause additional local irregularities of the outer surface of the receiver, which serves for engagement with lanceolatum rim of the capsule during use. These additional local irregularities can relate to the grooves, i.e. the local recesses of the outer surface of the receiver or protruding parts, i.e., local elevations of the outer surface of the receiver.

By creating lanzoprazole rim of the capsule, at least one protrusion serving to interact with the surface of the receiver when using, thereby forming a sealing engagement with the receiver, referred to irregularities can be compensated.

It is clear that can be provided for different types of sealing engagement. E.g. the measures at least one projection may be made within the scope of the capsule to ensure a tight connection among at least one protrusion and the surface of the receiver, which is designed to interact with the capsule during use. It is clear that the experts in the art, knowing the shape and dimensions of the outer surface of the receiver, intended for coming in contact with capsule can determine which area of the capsule must be created, at least one projection for education referred to the tight junction.

Minor surface irregularities can be compensated for by creating at least one protrusion having a modulated surface containing textured material. Modulated surface can be set spaced at regular intervals of recesses and elevations, and the height difference of the recesses and elevations is at least 0.05 mm, preferably at least about 0.15 mm, it Was found that such an embodiment is effective for creating a corresponding compacted interaction between lanceolatum protrusion and the surface of the receiver when the latter has recesses and protrusions.

In the embodiment, the capsules according to the invention, at least one protrusion is a district referred by the Yu to lanzoprazole the rim. However, it is clear that the so formed ring protrusion need not necessarily be circular. Can also be provided with a circumferential ledge of irregular shape adapted for engagement with the surface of the receiver. Such circumferential ledge of irregular shape might have rotational symmetry. This alternative implementation is described in more detail with reference to the figures.

Found that although at least one protrusion may be placed in selected areas lanzoprazole rim, which may have a surface of irregular shape, for example in separate areas on the periphery lanzoprazole rim, the preferred implementation, at least one protrusion in the form of a ring structure, so in order to preserve rotational symmetry for placing capsules in the receiver device for making beverages.

In yet another additional embodiment of the capsule according to the invention, at least one projection includes a member adapted to hold a fluid medium.

Found that particularly preferred is the selection of the at least one protrusion, which serves for the formation of sealing engagement with the receiver, a material adapted to hold a fluid medium. Thanks to this feature successfully compensated mikroskopicheskie defects in sealing engagement, that is due to absorption of fluid by the material of the ledge. It is preferable that such a material use of a spongy material.

In yet another additional embodiment of the capsule according to the invention has many separate elongated projections, these projections form methoprene region.

It is established that a reliable sealing engagement is achieved when creating the multielement ledge, for example, when creating methoprene design on lanzoprazol the rim of the capsule. This can be for the reason that extra long individual projections may be bent or otherwise deformed by the receiver, essentially without affecting the position in the space adjacent to the elongated protrusion. As a result, for example, when the surface of the receiver, intended for coming in contact with the capsule during use, contains a recess, this recess may be filled or otherwise compensated elongated protrusions, such as setae, with adjacent elongated projections essentially not affected.

In yet another additional embodiment of the capsule according to the invention, elongated individual projections have different heights.

It is established that the local difference in height of the surface of the receiver may be the effect is positive offset, if the individual elongated elements methoprene structures have different height. It is preferable that the formation of sealing engagement select base height, when there is unevenness of the receiver. Some extra long items will have more height to compensate local surface irregularities caused by the grooves. It is preferable that the height of the elongated separate protrusions is in the range of 0.1-2 mm, preferably in the range of 0.13-1 mm, more preferably in the range of 0.15-0.5 mm found that good results were achieved when the height of the elongated separate protrusions was about 0.25 mm, Preferably such methoprene design on lanzoprazol the rim of the capsule to compensate for significant surface irregularities, such as cracks, cavities on the surface, resulting, for example, due to wear and so on

In addition, it is clear that the elongated elements can be placed on the basic design, or, alternatively, the elongated elements may be made in the form of a set of grooves formed on the raised ground. Also in this case, the height of the elongated structures, measured by their vertices, is in the range of 0.1-2 mm, preferably in the range of 0.13-1 mm, more preferably in the range of the region of 0.15-0.5 mm It is clear that such height may be measured relative to the base surface lanzoprazole rim of the capsule. This alternative implementation is described in more detail with reference to the figures.

In addition, it is clear that such elongated structures can be made of a material that can deform. In an extreme situation elongated structure may be capable of essentially completely straightened. Extra long design can have a triangular, circular or any other appropriate section.

In an alternative embodiment, the tab on lanzoprazol the rim may be essentially flat, with a height in the range of 0.8 to 1.0 mm, and the protrusion is preferably made of a soft material that can deform. Specialists in the art will easily determine what class of materials, preferably plastics can be used to perform this ledge.

In yet another additional embodiment of the capsule according to the invention, at least one projection includes many interconnected tubular structures.

It is established that such an implementation option mainly combines the features of a material, capable of retaining the fluid and material that is capable of individual deformation, like a brush.Preferably, what many interconnected tubular structures contains polygonal structures, such as honeycomb structures. When interacting with the surface of the receiver with either a protrusion or a recess, a series of tubular structures may in places be deformed, essentially providing adjustment to the geometry of the local roughness (deepening or extension). It is preferable that the height of the tubular design picked so that the number of tubular structures, at least slightly deformed upon contact with the surface of the receiver to form a sealing engagement.

In yet another additional embodiment of the capsule according to the invention, at least one projection includes an inclined jumper extending between lanceolatum rim and wall.

This technical measure is based on the understanding that leakage can occur in the region where the vertical wall of the capsule is in contact, essentially, with horizontal and flat lanceolatum rim. To ensure sealing engagement with the receiver when using, glanceability rim equipped with a slanted design, which can function as a fitting between the receiver and the other essentially rectangular geometry of the junction of wall and rim.

It is clear that peremyslova design which can be created around the entire circumference of the rim adjacent wall, or, alternatively, may be placed an appropriate number of separate peremychkami elements.

In yet another additional embodiment, a capsule, a jumper consists of two or more bends, branches off from the base section attached to lanzoprazole the rim.

Found that by creating two branches off of branches, you can achieve additional flexibility in the adjustment of local surface irregularities of the receiver.

In yet another additional embodiment, a capsule, at least one protrusion is flexible. Preferably, at least one protrusion is elastically deformable.

In yet another additional embodiment, a capsule, at least one projection includes circumferential edge. It is established that such circumferential edge may, for example, be a local deformation to adapt to any unevenness in the surface of the receiver. Preferably, at least one protrusion contains many circular ribs.

For example, the capsule can be fitted with a Cup containing a circumferential wall, a bottom closing the circumferential wall at the first end, glanceability rim extending outside circumferential wall at a second end opposite the bottom, and the cover, when using the connected with funzionamento, when this wall, bottom and cover, when used, enclose the inner space containing the extractable product, and the Cup further comprises a multitude of essentially concentric circular ribs extending from the outside of the Cup, and the ribs are made of the same material as the Cup.

When using at least one of the circumferential ribs can tightly abut at least a section covering element, so that, for example, between the upper part of at least one edge and at least one area of the receiver, for example, the covering element is formed sealing engagement. Because there are many edges, Pets mismatch between the capsule and covering element, while still forms a sealing engagement.

In General, at least one protrusion can be made of the same material as the Cup. Thus, it can be created, at least one relatively inexpensive ledge.

It is preferable that at least one projection such as a rib or ribs, located on lanzoprazol the rim, for example, by lanzoprazole rim, pointing from the cover. Thus, at least one projection such as a rib or ribs may adjoin densely to the front end of the covering element. Thus, sealing is the emotional engagement may be formed at the location of lanzoprazole rim.

At least one projection such as a rib or ribs may be constructed as a unit with lanceolatum rim. Thus, manufacture of the Cup may include the production of at least one protrusion, such as a rib or ribs, for example, by way of injection molding, node Cup and at least one protrusion, such as a rib or ribs. Thus, there may be provided a slight Cup manufacturing capsules.

In one of the embodiments, each edge from the set of edges has essentially the same height to use. Thus, each edge from the set of edges may facilitate sealing engagement between the capsule and the covering element. Each edge from the set of edges can have essentially the same width.

The width of the ribs from the set of edges is less than the height of the ribs. Preferably, it relates to each edge of the set of edges. Thus, the rib has a flexible form, providing easy deformation of the ribs, for example, by clicking on the top edge of the ribs towards the base of the ribs. Accordingly, the edge can easily enter into the roughness of the covering element at the location of the sealing engagement, such as a recess and/or protruding portion at the front end of the covering element.

It is preferable that the edge of the multitude of the tion of the ribs has a width, which is equal to or less than the thickness lanzoprazole rim. It is preferable that an edge from a set of ribs has a height that is equal to or less than the thickness lanzoprazole rim. Preferably, it relates to each edge of the set of edges. Accordingly, the resistance of the compression ribs may be less resistance to compression of the rim. Thus, the rim can be hard compared to the rib, the rib may have sufficient compressibility due to its shape and/or dimensions to ensure sealing engagement with the covering element, even if the covering element contains the unevenness in the location of the sealing engagement.

An edge from a set of ribs may have a height of more than 0.3 mm, preferably more than 0.21 mm, more preferably more than 0.15 mm, the Edge from the set of edges may also have a maximum width of more than 0.3 mm, preferably more than 0.21 mm, more preferably more than 0.15 mm, Preferably, it relates to each edge of the set of edges. It is established that these dimensions provide a good sealing engagement between the rib and the covering element.

In one embodiment, the implementation of the edge from the set of edges is tapered, for example, essentially triangular cross-section. This preferably applies to each edge of the set of edges. This Mae is the advantage of the compression ribs require incremental effort. Accordingly, the edge can easily follow the contour of uneven covering element, as this will provide locally increased stress on the edge.

Preferably all edges from the set of edges have the same shape of the cross section.

In one embodiment, the radial distance between two adjacent ribs is smaller than the maximum width of the ribs, preferably less than 50% of the maximum width, more preferably less than 25% of the maximum width. Thus, edges are close to each other, providing a good chance that at least one of the edges properly tightly adjoins the covering element, in addition this provides sufficient space for expansion of the ribs due to compression. Closely spaced ribs also provide enhanced tolerance to misalignment of the capsule relative to the covering element, because of the close space between the ribs may form a labyrinth, providing sufficient resistance to the flow of fluid to create a sufficient sealing engagement between the capsule and covering element, even if no edge is not directly adjoins the covering element.

It is preferable that the cover is connected with glanceable the NYM rim, and the interior space at least partially filled with the extractable product. Accordingly, there is a ready-to-use capsule. The capsule can be sealed, for example, to increase the shelf life capsules. Alternatively, the lid and/or bottom is porous and/or contains openings to allow the flow of fluid in the inner space and/or exit of fluid from him.

In one embodiment, the capsule is disposable. Disposable capsule is so designed that after a single use, it must be disposed of. Thus, it can be minimized problems associated with hygiene, for example, the increase in the number of microbes.

Preferably, the capsule is designed to prepare a single serving of a beverage.

The invention also relates to the preparation of a given amount of beverage suitable for consumption using the extracted product containing (i) the capsule according to the invention, and (ii) a device for preparing drinks containing the receiver to interact with the capsule, for example, the covering element to accommodate the capsule, in which, when using at least one protrusion, for example, at least one of the ribs, tightly adjacent, IU the greater extent, the plot of the receiver, for example, the covering element, forming a sealing engagement between the capsule and the receiver, for example, the covering element.

In one embodiment, at least a section of the front end of the covering element is configured to close abutment, at least one of the ribs. Thus, edges can be placed on lanzoprazol the rim of the capsule.

It is preferable that each edge has a unique width which is less than the width of the front end of the covering element. This gives the advantage that the ribs are narrow relative to the front end of the covering element. Thus, the ribs can easily be adapted, for example, to small bumps, for example, deepening, scratch, crack, and/or serving on the front end of the covering element.

Preferably, the set of edges has a total width that is greater than the width of the front end of the covering element. Accordingly, provides a significant tolerance to misalignment of the capsule relative to the front end of the covering element.

An edge from a set of ribs may have a height which is less than the width of the front end of the covering element. This preferably applies to each edge of the set of edges. Thus, the rib and eat small height relative to the width of the front end of the covering element. This can prevent the curvature of the edges, which provides a good sealing engagement between the front end of the covering element and the ribs.

The invention also relates to a method for preparing a predetermined quantity of beverage suitable for consumption using the system according to the invention.

These and other objects of the invention will be described in more detail with reference to the drawings, in which identical reference position are identical to the elements. It is clear that the drawings are presented for illustrative purposes and may not be used to limit the scope of the attached claims.

Detailed description of drawings

In Fig.1 shows a schematic representation, in section, of a first example of a system 1 for the preparation of a given amount of beverage suitable for consumption using the extracted product. The system 1 includes a replaceable capsule 2 and the device 4 for the preparation of drinks. The device 4 comprises a receiver in the de covering element 6 to accommodate the exchangeable capsule 2. In this example, the device 4 further comprises a supporting element 8 for fixing the capsule 2.

In Fig.1 for clarity drawn the gap between the capsule 2, the covering element 6 and the supporting member 8. It is clear that when using the capsule 2 may be in contact with the covering element 6 and the supporting member 8. Typically, the covering element 6 has a shape complementary to the shape of the capsule 2. Apparatus 4 further comprises a device 10 of the issuing fluid for feeding portions of a fluid medium, such as water, under pressure, for example bar 9, exchangeable capsule 2.

In the example shown in Fig.1, the exchangeable capsule 2 includes a Cup 12 and lid 14. In this example, the Cup 12 includes a circumferential wall 16, a bottom 18, a closing ring wall 16 at the first end, and glanceability rim 20 extending outside circumferential wall 16 at a second end opposite the bottom wall 18. Circumferential wall 16, a bottom 18 and the cover 14 closes the inner space 22 containing the extracted product. In this example, the capsule is initially sealed, i.e., hermetically closed before using.

System 1 shown in Fig.1, contains Dneprorudnoe means 24 for punching the bottom 18 of the capsule 2, with the goal of creating at least one inlet port 25 in the bottom 18 for supplying a fluid medium on the extractable product through the inlet 2.

System 1 shown in Fig.1, further comprises chrysikopoulos tool 26, which is designed in the form of protrusions of the support element 8, which serves for punching the cover 14 of the capsule 2. Chrysikopoulos tool 26 may be adapted to divide the cover 14 when the excess pressure (fluid) in the inner space 22 of the threshold pressure and the pressing cap 14 to Krasnoprudnaya tool 26 with sufficient force. Cover 14 may, for example, contain breaking the foil, for example, made from aluminium.

In this example, the Cup 12 further comprises a set of protrusions in the form of essentially concentric circular ribs 28.i (i=l, 2, 3). In this example, the ribs 28.i posted on lanzoprazol the rim 20. Here the ribs 28.i posted from lanzoprazole rim 20 pointing from the cover 14. More generally, the ribs 28.i extend outside of the Cup 12. In this example, the ribs 28.i made of the same material as the Cup 12. In this example, the ribs 28.i made as one piece with the Cup 12.

As can be seen from Fig.1 when using the ribs 28.i can adjoin densely to the front end 30 of the covering element 6. When in this example, at least one edge 28.i tightly adjoins at least a section of the front end 30 of the covering element 6, it turns out the sealing engagement between the cover is yuushin element 6 and the capsule 2 in place where at least one edge 28.i tightly adjoins at least a section of the front end of the covering 30 item 6.

System 1 shown in Fig.1, operates as follows to prepare a Cup of coffee, while the extractable product is a roast and ground coffee.

The capsule 2 is placed in a covering element 6. The supporting element 8 is brought into contact with the capsule 2. Dneprorudnoe means 24 breaks through the bottom 18 of the capsule 2 to create openings 25. Fluid, in this case hot water under pressure is fed to the extracted product in the inner space 22 through the inlet 25. Water will moisten the coffee beans and extracts the necessary substances for the formation of a coffee drink.

When the supply of water under pressure in the inner space 22 of the pressure inside the capsule 2 will increase. The increase in pressure will lead to deformation of the cover 14 and is clamped to Krasnoprudnaya means 26. Upon reaching a certain pressure level, the tensile strength of the cover 14 is overcome and the cover will be broken on chrysikopoulos means 26, creating exit holes. Coffee will result from the capsule 2 through the outlet and the outputs 32 of the support element 8 and can be served in a container such as a Cup (not shown).

In Fig.2 presents a schematic view of another variant of the westline capsules according to the object of the present invention. This figure shows a schematic vertical cross-section plot of the capsule. Capsule 110 includes a wall 102 having an inner surface 102b, designed for education, at least, part of the internal space I for the placement of the extracted product. The outer surface 102a of the capsule may be orthogonal or oblique location in relation to lanzoprazole the rim 104. Planteary rim 104 includes upper surface 104a, designed for interaction with surface 109 of the receiver 108 of the device for making beverages. Planteary rim 104 may have an essentially flat area between the base wall 102a and the end ring 106. End ring 106 may be installed for including centering receiver 108 relative to the capsule. It is clear that the receiver 108 may have a shape for receiving the capsules 110 that section 108 is, essentially, to cover it.

According to the object of the invention to education sealing engagement between the capsule 110 and the surface 109 of the receiver when using the surface area 104a provided with a protrusion 107. It is clear that the protrusion 107 can be done essentially anywhere along the width L lanzoprazole rim. Also how to use the ledge 107 for education sealing engagement may be different.

First, the protrusion 107 mo is et to be placed, in which wall 102 intersects with lanceolatum rim 104, so that the surface 109 essentially rests on the ledge 107. This gives the advantage that the protrusion may be slightly compressed, so that the local surface irregularities of the receiver 108 are offset. For example, when selecting the material for the projection, capable of holding the fluid, can be neutralized microscopic leakage from the joint between the rim and the receiver.

Secondly, the protrusion 107, for example a spongy element, can be placed near the outer ring 106 so that it can also close the tight junction to the surface 109 of the receiver to enter into engagement with the vertical outer surface. In this case, essentially, the ledge can provide improved sealing engagement because of the extreme outer surface of the receiver 108 may be at least partially covered by a spongy element 107.

In Fig.3 presents a schematic view of a variant of implementation of the capsules according to the object of the invention, in which the geometric shape of the capsule 120 and receiver 108 are essentially the same as described with reference to Fig.2.

In this particular embodiment, the tab contains a number of separate elongated elements 117, with a separate elongated elements may have the same height or may have times which ranks height h1, h2. It is clear that discusses the various options for implementation of separate elongated elements. First, the items can be made in the form of methoprene design, which can be glued to the surface 104a using an appropriate adhesive. The individual elements can be made of plastic, synthetic bristles, and the like. Individual elements may, for example, be made of the same material as the Cup 102, 104, 106. Individual elements may, for example, be designed as one piece with the Cup, for example, by simultaneous injection molding cups and items. The protrusion 117 may be made in the form of ring structures on the periphery of the rim of the capsule. It is preferable that the ring structure is concentric with the axis of rotation of the capsule (not shown). Can be created several located around the circumference of the protrusions 117. For example, one circumferential protrusion may be made at the junction of the rim and the wall or near it, and the second circumferential protrusion can be located at the junction of the rim and ring, thereby providing a second barrier to the possible microscopic leaks. As an additional or alternative option, the protrusion 117 may be made in the form of a few isolated areas on the surface 104a. Such areas can be performed in a two-dimensional is dressed, for example a model in a checkerboard pattern, or can be performed according to another suitable model. In the example shown in Fig.3, the individual elements are drawn straight. It is clear that the individual elements can also be curved or twisted. It is clear that the elements can be bound, for example, forming Sherstobitov design. This Serleena design can be made by way of injection molding together with a Cup.

In Fig.4 presents a schematic view of a variant of implementation of the capsules according to the object of the invention, in which the geometric shape of the capsule 130 and receiver 108 are essentially the same as described with reference to Fig.2.

In this particular embodiment, at least one projection includes a textured material 127, which can be positioned anywhere across the width L of the surface 104a. Also in this case, the protrusion 127 may be made in the form of one or more of district structures or in separate areas. Material 127 preferably includes recesses and protrusions. It is preferable that the difference in height between adjacent recesses and protrusions is at least about 0.5 mm.

In Fig.5 shows a schematic view of a variant of implementation of the capsules according to the object of the invention, in which the geometry is practical form of capsules 140b and receiver 108 are essentially the same as described with reference to Fig.2.

In the top view shows a section 140a of the capsule, which on the surface 104a between the ring 106 and the wall 102a has a ledge containing multiple interconnected tubular structures. Although in this particular example shows the tubular cell design, any shape cross-section. Preferred may be polygonal cross-section, as any tubular structure connected with many adjacent tubular structures, which increases the flexibility of such a protrusion in the vertical direction V.

The tubular design can be placed on the peripheral surface 104a, or it can be performed in selected areas. The ledge containing the hollow tubular elements may have the advantage that these elements can easily be compressed by a receiver (not shown) to form a sealing engagement. The internal volume of the tubular elements may be used as microscopic vessels for receiving fluid flowing from sealing engagement that could further improve the sealing engagement.

In Fig.6 presents a schematic view of a variant of implementation of the capsules according to the object of the invention, in which the geometric shape of the capsule 150 and receiver 108 are essentially the same as what you described with reference to Fig.2.

In this particular embodiment, at least one projection made in the form of jumpers between the surface 104a and a wall 102a. It is preferable that there are many jumpers 147a, 147b, 147c,... 147n. It is clear that peremyslova design can be made in the form of an inclined connection with the base section 153 on the surface 104a and end sections, ending with a wall 102a. Alternatively, the jumper can be made in the form of triangular or prismatic filler between the surface 104a and a wall 102a. In both cases, the jumper may have two or more branches 151, 152, with one base and split, as well as wall 102a. In addition, it is clear that although the basic plot 153 schematically located near the junction of the rim and wall, it can be placed at a significant distance from the interface. Various individual peremychkami designs can also be differently located base stations. Alternatively, can one located around the circumference peremyslova design connecting surface 104a of the rim and the wall 102.

In Fig.7 shows a schematic representation, in section, of a second example of the system 1 described with reference to Fig.1 for the preparation of a given amount of beverage suitable for use is the consumption, using the extracted product. The system 1 includes a replaceable capsule 2 and the device 4 for the preparation of drinks. The device 4 comprises a receiver, in this case, the covering element 6, to accommodate the exchangeable capsule 2. In this example, the device 4 further comprises a supporting element 8 for fixing the capsule 2.

In Fig.7 for clarity drawn the gap between the capsule 2, the covering element 6 and the supporting member 8. It is clear that when using the capsule 2 may be in contact with the covering element 6 and the supporting member 8. Typically, the covering element 6 has a shape complementary to the shape of the capsule 2. Apparatus 4 further comprises a device 10 of the issuing fluid for feeding portions of a fluid medium, such as water, under pressure, for example bar 9, exchangeable capsule 2.

In the example shown in Fig.7, the exchangeable capsule 2 includes a Cup 12 and lid 14. In this example, the Cup 12 includes a circumferential wall 16, a bottom 18, a closing ring wall 16 at the first end, and glanceability rim 20 extending outside circumferential wall 16 at a second end opposite the bottom wall 18. Circumferential wall 16, a bottom 18 and the cover 14 closes the inner space 22 containing the extracted product. In this example, the capsule is initially opened. Accordingly, the capsule 2 has previously done WMOs the major holes 25. The inlet 25 can be a through hole in the bottom 18. In addition, the capsule 2 has pre-done output apertures 27. The outlet port 27 may be a through hole in dolgobrodskoy the cover 14, for example made of plastic, or may be the pores in the porous cover made, for example, from non-woven material, such as filter paper.

System 1 shown in Fig.7, does not contain dneproblnergo funds or chrysikopoulos means 26.

In this example, the Cup 12 also contains many essentially concentric circular ribs 28.i (i=l, 2, 3, ...). In this example, the ribs 28.i posted on lanzoprazol the rim 20. Here the ribs 28.i posted from lanzoprazole rim 20 pointing from the cover 14. In a more General sense of the ribs 28.i extend outside of the Cup 12. In this example, the ribs 28.i made of the same material as the Cup 12. In this example, the ribs 28.i made as one piece with the Cup 12.

As can be seen from Fig.7, when using the ribs 28.i can adjoin densely to the front end 30 of the covering element 6. When in this example, at least one edge 28.i tightly adjoins at least a section of the front end 30 of the covering element 6, there is formed a sealing engagement between the covering element 6 and maintain the nd 2 place where at least one edge 28.i tightly adjoins at least a section of the front end of the covering 30 item 6.

System 1 shown in Fig.7, operates in the following manner to prepare a Cup of coffee, while the extractable product is a roast and ground coffee.

The capsule 2 is placed in a covering element 6. The supporting element 8 is brought into contact with the capsule 2. Fluid, in this case hot water under pressure is fed to the extracted product in the inner space 22 through the inlet 25. Water will moisten the coffee beans and extracts the necessary substances for the formation of a coffee drink.

When the supply of water under pressure in the inner space 22 of the pressure inside the capsule 2 may increase. Coffee will result from the capsule 2 through the outlet 27 and the outputs 32 of the support element 8 and can be served in a container such as a Cup (not shown).

In Fig.8a and 8b shows enlarged views of parts of the system 1 according to the invention. In this example, four circumferential ribs 28.i posted on lanzoprazol the rim 20. Here the ribs 28.i made as one piece with the rim 20. In this example, the ribs 28.i placed concentrically in relation to one another. In this example, the ribs 28.i also made concentrically relative to the axis of the Cup 12.

In Fig.8a, the front end 30 covers the existing item 6 is an irregularity in the form of a protruding part 34, for example the boss, Burr or coma (for example, remelted scrap). In this example you can see that one single edge from 28.3 number of ribs 28.i tightly adjacent to the protrusion 34 and locally tighter. Accordingly, the ribs 28.i and the covering element 6 are in sealing engagement, despite the presence of the protruding part 34.

In Fig.8b, the front end 30 of the covering element 6 is an irregularity in the form of notches 35 or cavities, such as dents, scratches or cracks. In this example you can see that one single edge 28.2 of the number of ribs 28.i turned to the notch 35. The adjacent edge 28.3, respectively, will be locally more compressed and firmly joined to the front end 30 of the covering element 6. Accordingly, the ribs 28.i and the covering element 6 are in sealing engagement, despite the presence of the notches 35.

In the examples shown in Fig.8a and 8b, each rib 28.i has an essentially triangular cross-section. This gives the advantage that the compression of the ribs 28.i require incremental effort. Accordingly, each rib 28.i can easily follow the contour of uneven covering element 6.

In the examples shown in Fig.8a and 8b, all edges have essentially the same height HRbefore using, for example, before compression. Accordingly, all of the ribs 28.i can equally facilitate the performance by the sealing engagement between the capsule 2 and the covering element 6. Thus, misalignment between the capsule 2 and the covering element 6, while the front end 30 is not closely adjacent to any of the ribs 28.i.

In the examples shown in Fig.8a and 8b, each of the ribs 28.i has a maximum individual width of WRwhich is less than the width WLEthe front end 30 of the covering element 6. Thus, each rib 28.i is a relatively narrow front end 30, so that each edge 28.i can easily compress the front end 30. In addition, there are a lot of ribs 28.i has a total width of WCthat is greater than width WLEthe front end 30 of the covering element 6. Thus, misalignment between the capsule 2 and the covering element 6, while the front end 30 is not closely adjacent to any of the ribs 28.i. It is clear that in General the width of the individual elements, at least one protruding part may be less than the width of the part of the receiver that is used to interact with the capsule. It is also clear that in General the width of the at least one protruding part may be greater than the width of the part of the receiver that is used to interact with the capsule.

In these examples, the width WReach of the ribs 28.i is less than the height HRthis edge before use. Accordingly, the ribs 28.i have a flexible shape that provide the AET easy deformation of the ribs 28.i, for example, by clicking on the top edge 36 of the ribs towards the base 38 of the ribs 28.i. Accordingly, the ribs 28.i can easily follow irregularities in the covering element 6 at the location of the sealing engagement. It should be noted that the width WRedge measured parallel to the plane on which the rib, and that the height HRribs is measured orthogonal to the width.

In these examples, the width WReach of the ribs 28.i is less than the thickness of the HFlanzoprazole rim 20. Also in these examples, the height HReach of the ribs 28.before i use less than the thickness HFlanzoprazole rim 20. Accordingly, the resistance to compression of the ribs 28.i may be less resistance to compression of the rim 20. In these examples, the rim 20 is relatively rigid ribs 28.i, while the ribs 28.i can have sufficient compressibility due to its shape and size to provide sealing engagement with the covering element 6, even if the covering element contains the unevenness in the location of the sealing engagement. It is clear that the ratio of the resistance of the compression ribs 28.i to resist compression of the rim 20 can be further improved by increasing the thickness of the rim 20, at least locally, at the location of the ribs 28.i.

The geometry of the ribs 28.i allow the ribs 28.i lighting is Itsa to irregularities on the covering element 6, even if the selected material, which allows the rest of the Cup 12 to be essentially rigid. This essentially rigid Cup 12 can increase the ease of handling of the capsule 2. For example, the ribs 28.i can be executed as a single unit with lanceolatum rim 20, the circumferential wall 16, and possibly with a bottom 18, for example, of plastic. It is established that in this case, the Cup 12 may be essentially rigid, while the ribs 28.i can interact with the covering element 6 to ensure sealing engagement, even if the selected plastic is D hardness shore component 70 units or more.

In these examples, the thickness of the rim 20 is about 0.2 mm. In these examples, the width of the front end 30 of the covering element 6 is approximately 0.7 mm In these examples, the height HReach of the ribs 28.i is equal to approximately 0.2 mm before use. Preferably the height HRis more than 0.3 mm, more preferably more than 0.21 mm, height HRcan also be more than 0.15 mm before use. In these examples, the maximum width WReach of the ribs 28.i is approximately 0.14 mm

Width WRis preferably more than 0.3 mm, more preferably more than 0.21 mm, most preferably more than 0.15 mm. found that these dimensions provide the chorus of the neck sealing engagement between the ribs 28.i and the covering element 6.

In the examples shown in Fig.8a and 8b, the ribs 28.i posted radially in such a way that two adjacent edges, essentially radially aligned. In a broader sense, the radial distance between two adjacent ribs 28.i preferably less than the maximum width WRribs 28.i, more preferably less than 50% of the maximum width WRmost preferably less than 25% of the maximum width WR. Thus, the ribs 28.i are located close to each other, providing a good chance that at least one of the ribs 28.i duly tightly adjacent to the front end 30 of the covering element 6. Closely spaced ribs 28.i also provide an increased tolerance to misalignment capsules 2 relative to the covering element 6, since the narrow space between the ribs 28.i can form a maze, providing sufficient resistance to the flow of fluid to create a sufficient sealing engagement, even if none of the ribs 28.i do not directly adjoins the covering element 6.

In a preferred embodiment according to Fig.8a or Fig.8b ribs 28.i made as one piece with the Cup 12. Node Cup 12 and the ribs 28.i can, for example, be manufactured by injection molding as a single piece. The site can be made of plastic, for example polypropylene PP is Lena.

In a preferred embodiment, pick the plastically deformable material of the ribs 28.i. It is preferable that the ribs 28.i, at least, the upper part 36 of the ribs can plastically deform upon contact with the covering element 6. Plastically deformable ribs 28.i can easily adapt to the irregularities of the covering element 6 at the location of the sealing engagement.

It is clear that the details shown in Fig.8a and 8b, can be used in the system described in Fig.1, as well as in the system described in Fig.7.

In Fig.9 shows the enlarged view of part of a carefully designed system 1 according to the invention. In this example, in addition to the set of edges 28.i, the capsule 2 contains an additional edge 40.

In Fig.9 additional rib 40 is located on lanzoprazol the rim 20, with the hand pointing from the cover 14. Here additional rib 40 is made as one unit with lanceolatum rim 20. In this example, the additional rib 40, essentially, is concentric with the ribs 28.i. Here additional rib 40 is located so that it describes the ribs 28.i. It should be noted that the height HFRadditional ribs 40 is different from a height of HRribs 28.i. In this example, the height HFRadditional ribs 40 is greater than height HRribs 28.i.

In this case Ebro 40 is configured to close abutment to the outer circumferential surface 42 of the covering element 6. The outer circumferential surface 42 may be podchinena to the inner circumferential surface 44 additional ribs 40. To facilitate the insertion of a covering element 6 along the perimeter of the extra edge 40, an additional rib 40 may include a tapered section 46 on the inner circumferential surface 44.

Thus, in this example, at least one of the ribs 28.i tightly adjoins the covering element 6, and, furthermore, an additional rib 40 tightly adjoins the covering element 6. Accordingly, there is formed an improved sealing engagement between the capsule 2 and the covering element 6.

It is clear that additional edge 40 may also be applied in the situations described with reference to Fig.1, 7, 8a and 8b. It is clear that additional edge 40 may also be used in combination with any of the tabs described with reference to Fig.2-6.

In Fig.10a shows a schematic representation of an additional example of a system 1 according to the invention. System 1 shown in Fig.10a is essentially identical to the system shown in Fig.1. In Fig.10a, however, the location of the at least one protrusion, in this case, the ribs 28.i, on the Cup 12 is different. In this example, at least one protrusion, in this case, the ribs 28.i, is located on the circumferential side wall 16 of the Cup 12. Here, at least one speaker is, in this case, the ribs 28.i closely adjacent to the inner peripheral surface 48 of the covering element 6. In Fig.10a, at least one protrusion, in this case, the ribs 28.i, and the inner circumferential surface 48, are in sealing engagement. It is clear that in the system shown in Fig.2-7 at least one protrusion, for example, ribs 28.i can be located on a circumferential side wall 16 of the Cup 12.

In Fig.10b shows a schematic illustration of an additional example of a system 1 according to the invention. System 1 shown in Fig.10b is essentially identical to the system shown in Fig.7. In Fig.10b, however, the location of the at least one protrusion, in this case, the ribs 28.i, on the Cup 12, is different. In this example, at least one protrusion, in this case, the ribs 28.i, is located on the outer surface of the bottom 18 of the Cup 12. Here, at least one protrusion, in this case, the ribs 28.i closely adjacent to the inner rear surface 50 of the covering element 6. In Fig.10b, at least one projection, i.e., the ribs 28.i, and the inner rear surface 50 are in sealing engagement. It is clear that in the system shown in Fig.1-6, at least one protruding portion, for example, ribs 28.i can be located on the outer surface of the bottom 18 of the Cup 12.

In Fig.11 schematically shows a variant is sushestvennee additional example of a capsule according to the invention. On the 160 schematically shows a section of a longitudinal section of a capsule according to an additional object of the invention. It is clear that the common parts are not described with reference to this figure can be found with reference to figure 2.

Pursuant to this object of the invention, the capsule 160 and the surface 109 of the receiver when using a form, essentially sealing engagement when the surface 109 of the receiver 108 intersects with elongated structures 164.

It is preferable that the height lanzoprazole rim 104 at the periphery of the capsule about 160 of the outer ring 106 may be about 0.2 mm long structure 164 can be placed on the protrusion 162, which may have a height of 0.5-0.7 mm, measured from the bottom surface 104a lanzoprazole rim, see position H1. Extra long design 164 may be about 0.25 mm (see position h2), which leads to a General rise lanzoprazole rim in this area up to 0.8-1 mm.

It was found that by creating a local elevation lanzoprazole rim in the area adjacent to or connecting with the outer surface of the capsule 102a, is improved sealing engagement between the capsule and the receiver. Due to the fact that elongated structures can be omitted or otherwise individually deformed, as a sealing engagement is greatly improved.

In Fig.Thematically presents an implementation option of one additional example of a capsule according to the invention. In this embodiment, shown are two options that can be used separately or in combination.

For clarity, the positions described with reference to figures 2 and 11, there will not be repeated unless they are modified.

In the first embodiment, the surface lanzoprazole rim can be raised up to the level of H3, which may be of 0.8-1.0 mm, Thus, a significantly elevated ledge, which can be seamlessly connected to the outer surface of the capsule 102a. It is preferable that the protrusion 104" made essentially of soft and deformable material. More preferably, the capsule is made of the same soft and deformable material, whereby the protrusion 104" essentially integrated with it. For example, such a construction can be obtained by appropriate casting technology.

Secondly, the raised protrusion 104 may be equipped with elongated protrusions 164", which can be made in the form of corresponding grooves in the body of the ledge 104. Thus, the local deforming properties of the protruding part has substantially increased because the elongated structure 164 can deform individually. It is clear that the elongated structures can be located on a piece of raised protrusions 104, or they can cover a whole in the J. his side.

In Fig.13 schematically shows a top view of the relevant district protrusion having an irregular shape. The protrusion 180 is located on lanzoprazol the rim, so that it intersects the trajectory that should be occupied by the surface receiver. It is clear that it is possible an appropriate variety of forms ledge 180, including zigzags, mazes, etc. can Also be created many coherent irregular forms a, b.

In the above description the invention is described with reference to specific examples of embodiments of the invention. However, it is clear that this can be done various modifications and changes within the essence and scope of the invention as set forth in the accompanying claims.

For example, the capsule shown in Fig.7, may be used in the system shown in Fig.1. In this case, the capsule is made so that the bottom is not breaking depresivnim means. Cover and chrysikopoulos tool can be made so that the cover does not break under the pressure of the fluid in the inner space of the capsule.

It is clear that the covering element has a front end for close abutment to lanzoprazole the rim of the capsule, while the front end may also contain irregularities in the form of multiple radially of Postira the outstanding grooves. Also in this case, it may be formed by sealing engagement between the front end of the covering element and the edges of the capsule according to the invention.

The capsule can be filled or refillable capsules, which can respectively be filled or recharged by the user. Such a capsule may be made in the form of individual cups and lids, which can be connected to the Cup by the user, after filling the capsule ingredient of the drink. Alternatively, the cover can be partially, for example, hinge, connected to the Cup, so that the user can attach the cover essentially the entire perimeter lanzoprazole rim after filling the cups ingredient of the drink.

In the examples, the set of edges contains three or four ribs. It is clear that also can be used a different number of ribs, for example, two, five, or six ribs.

It is clear that while the above described specific embodiments of the invention, this invention may be practiced otherwise than described. In addition, can be combined individual characteristics described with reference to different figures.

However, there are also other modifications, variations and alternatives. The description, drawings and examples, respectively, should be considered illustrative and not to limit the flax sense.
