The present invention relates to a capsule for preparing a nutritional product containing nutritional ingredients by mixing the ingredients with a liquid, the capsule being designed for insertion in a device for supplying liquid to the capsule. More particularly, the present invention relates to a kit comprising such a capsule and dedicated opening means for enabling an opening thereof independent of a dedicated preparation device.

Background of the invention

Nutritional compositions can be, for instance, infant formulas or also nutritional liquids for toddlers, invalids, elderly people, persons having nutritional deficiencies or athletes.

In general, different forms in which nutritional compositions may be provided exist, each of them having their own advantages.

For instance, although the nutritional composition provided in a powder form have a relative high nutritional quality, the preparation thereof may be regarded as inconvenient and time consuming, since water which has been boiled in advanced and allowed to cool has to be poured into a drinking vessel containing the powder in order to prepare a liquid nutritional composition such as an infant formula. The same inconvenient preparation process exists for nutritional compositions in concentrated liquid form.

A more convenient preparation of a nutritional composition is enabled by capsule-based preparation devices in which a single-serving of a preferably powdered composition being provided within a cartridge or capsule is dissolved by means of injection with filtered respectively sanitized liquid such as water. Thereby, any undesired contaminants should be removed from the liquid before the liquid is mixed with the ingredients. For this purpose, such a device preferably comprises filter means for filtering respectively sanitizing the water. WO2006/ 077259 for example discloses a method for preparing a single serving of a nutritional composition comprising introducing liquid such as water into a cartridge containing a unit dose respectively single- serving of the composition in concentrated form. Thereby, the water is treated prior to the introduction into the cartridge in order to remove pathogens from the water. This treatment may be for instance a pre-heating, a filtering or an irradiation of the water with ultraviolet light.

WO 008/012314 relates to a device that teaches the principle of treating water by means of a filter used for the preparation of nutritional compositions from a capsule inserted in a dispenser.

A capsule with an integrated antimicrobial filter has been described in WO 2009/092629and No. 09156782.6 filed on 31 March 2009. In the known prior art, the nutritional ingredients are generally provided in powdered form within a body portion respectively a dedicated compartment within such a capsule. The interaction of the ingredients and provided liquid preferably takes place within the capsule respectively within the dedicated ingredients compartment of the capsule. Thereby, the opening of the usually sealed capsule is obtained by means of a beverage production machine to which the capsule is provided and which is equipped with dedicated opening means.

However, this known method suffers the drawback that for the preparation of the nutritional composition a dedicated beverage production machine is required. However, these beverage production machines are generally not portable and not available in any given place at which the consumer may wish to prepare a nutritional composition. Moreover, the capsule itself does usually not comprise any opening means in order to prevent a user from accidently opening the capsule.

Hence, there is the need for enabling an opening of the capsule by the consumer independent of the beverage production machine.

In particular, the consumer of the nutritional ingredients may wish to open the capsule in order to serve the ingredients to a provided receiving vessel or receptacle such that the consumer is enabled to manually prepare the nutritional composition by means of reconst i tut ion of the ingredients without a beverage production machine, e.g. upon addition of a suitable liquid such as water to the ingredients provided to the receiving vessel . Moreover, the user may wish to individually choose the dosage respectively the amount of nutritional ingredients to be served into a dedicated receiving vessel. Thus, a portable system is sought-after which enables a consumer to conveniently transport and provide respectively serve nutritional ingredients contained within a capsule or cartridge. The present invention seeks to address the above- described problem. The invention also aims at other objects and particularly the solution of other problems as will appear in the rest of the present description. Object and summary of the invention

In a first aspect, the present invention relates to a kit, comprising at least one capsule for insertion in a beverage production machine and containing nutritional ingredients, preferably infant formula ingredients, the capsule having a cup-like base body comprising an opening being closed off by an outlet face, and at least one capsule opening device provided separately to the capsule, the capsule and the opening device being provided with means for mechanically associating the opening device to the capsule by the consumer, preferably without using tools, the capsule opening device comprising an integrally formed opening member arranged to be operated by a user and designed for opening said outlet face of the capsule.

The present invention thus provides a kit that enables the fast and convenient opening of an outlet face of the capsule, independent of a beverage production machine. Hence, the user is enabled to conveniently transport the capsule and the capsule opening device of the kit in order to serve the nutritional ingredients provided within the preferably sealed capsule at any given location independent of additional stationary means such as a dedicated beverage production machine.

The at least one capsule of the kit preferably includes nutritional ingredients such as for example infant formula, suitable for interacting with liquid provided to the capsule in order to produce a cold or hot nutritional composition. Thereby, the nutritional ingredients are preferably in the form of a liquid concentrate, a paste, a gel or a powder. The kit may comprises a large variety of different capsules that preferably differ at least in the amount and/or nature of ingredients contained within the capsule.

The capsule of the kit preferably comprises a cup-like base body having an aperture such that ingredients can be filled to the interior defined by the body of the capsule. The aperture of the body of the capsule is preferably surrounded by a circumferential 1 y arranged flange-like rim portion to which the outlet face is sealed.

It is to be understood that the face covering the aperture of the body of the capsule is referred to as "outlet face" due to its function for being opened by the opening device in order to supply the nutritional ingredients from an opening created within said face. However, said "outlet face" may as well be used as a face for injection of liquid to the capsule when being placed in a dedicated beverage production machine. To this regard, the "outlet face" may as well be referred to as "inlet face" in conjunction with beverage production machines .

The term "without using tools" means that the user may associate the capsule and the capsule opening device of the kit essentially without the help of any additional means which are to be provided to the kit such as a mechanical press or a specific association tool. The kit may as well comprise a variety of different opening devices that can be chosen by the user to be associated to a particular capsule. Thereby, the opening devices preferably comprise at least different means for mechanically associating the opening device to the capsule by the consumer. Hence, capsules of different shape and/or size of the kit may be associated to and thus opened by means of the provided opening devices.

Moreover, the opening device of the kit may be equipped with opening members of different design and/or size.

Alternatively, the means for mechanically associating the opening device to the capsule by the user may be designed for being adapted to different shapes and/or sizes of the provided capsules.

The opening member of the opening device is preferably arranged in vicinity of the outlet face of the capsule when the opening device and the capsule are in their associated state. Thereby, the opening member comprises any means suitable for at least partially open a face and in particular the outlet face of the capsule.

The opening member comprises any means suitable for pinching, piercing, cutting or rupturing the outlet face of the capsule. In a preferred embodiment, the opening member is a cutting blade suitable for cutting the outlet face of the capsule. The cutting blade preferably comprises a V-edge. However, the cutting blade may as well be of different shape suitable for at least partially cutting the outlet face of the capsule.

The opening member is preferably made from metal or plastic suitable for opening the outlet face of the capsule. In particular, the opening member is preferably a metal or plastic blade suitable for cutting a plastic membrane preferably forming the outlet face of the capsule. More preferably, the opening member is a plastic blade in order to reduce the risk of small pieces being cut from the plastic membrane which may then be present in the composition provided from the capsule.

The opening member is preferably selectively connectable to the opening device and is thus removable respectively replaceable. Hence, a user may replace the opening member, e.g. for hygiene reasons or because it loses its sharpness .

In a preferred embodiment, the opening member is arranged movably relative to at least the means for mechanically associating the opening device to the capsule.

Moreover, the opening member is preferably arranged movably relative to the outlet face of the capsule when the capsule is associated to the opening device.

In a preferred embodiment, the opening member is designed for being at least brought from a first storage position to a second opening position. Thereby, when the opening member is in its first storage position, it is preferably at least partially retracted within a dedicated support or storage area preferably integrally formed with the opening device. Hence, a user is prevented from cutting himself with the opening member when handling the opening device .

In a second opening position, the opening member is preferably protruding from a face of the opening device ad acent to the outlet face of the capsule when the capsule is associated to the opening device of the kit. Thereby, the opening member preferably protrudes from the device to such an extent that the opening member at least partially penetrates the outlet face of the capsule such that cutting of the outlet face is enabled. When the opening member is brought from its first storage position to its second opening position, the opening member is preferably moved essentially within a plane parallel to the outlet face of the capsule in case the capsule is associated to the opening device.

The opening member may as well be moved in a direction essentially orthogonal to a plane in which the outlet face of the capsule is arranged when being brought from its first storage position to its second opening position. Hence, penetration respectively piercing of the outlet face by the opening member is obtained.

During further motion in its opening position, the opening member is preferably moved in a direction essentially parallel to the outlet face of the capsule, thereby cutting through the outlet face.

The opening member is designed to follow a predefined motion path with respect to the opening device and thus with respect to the outlet face of the capsule when the capsule is associated to the device. Thereby, the predefined motion path preferably comprises at least the above-described first storage position and the second opening position of the opening member. In a preferred embodiment, the motion path comprises a second storage position. Thereby, the first and the second storage positions are preferably present at the respective ends of the motion path. The motion path followed by the opening member is preferably in the form of an arc or a quadrant of a circle. Alternatively, the motion path may be of essentially semicircular form. Accordingly, the opening means following such a motion path are enabled to at least partially cut the outlet face of the capsule in order to create an aperture respectively an opening therein. The capsule opening device is preferably a separate element designed to be selectively applicable to the capsule .

Hence, the capsule and the opening device may be stored and transported independently of each other. Accordingly, the user is enabled to associate the capsule and the opening device of the kit directly before opening the capsule. Thus, the risk of a user accidently opening the capsule is significantly reduced. Furthermore, reusability of the opening device is enabled.

The opening device preferably comprises connection means designed for selectively connect and/or disconnect the opening device to/ from a rim portion of the capsule. The connection means may however be as well designed to selectively connect the opening device to another portion of the capsule such as e.g. the body portion of the capsule .

The connection means is preferably a connection groove. Thereby, the connection groove is preferably designed for being connected to an outer portion of a face of the capsule such as e.g. a circumferential rim portion of the capsule .

The connection means may as well be any other means suitable for associating the opening device to an ingredients containing capsule of the kit. In particular, the connection means may as well be a snatch member. Thereby, the connection means may comprise two snatch members at opposing side portions of the opening device in order to enable a stable support of the device ad acent to the outlet face of the capsule when being associated to it.

Alternative to a second snatch member, the opening device may as well comprise a joint preferably situated at a position opposite to the snatch member.

Moreover, the connection means may as well be an adhesive Thereby, the connection means may be in the form of a circumferential adhesive film applied on the capsule and suitable for selectively connecting the opening device to a face of the capsule. The adhesive film may be equipped with protection means such as e.g. a plastic cover that is to be removed by a user before connecting the opening device to a face of the capsule. Alternatively, the adhesive may be applied as a separate element to the kit, e.g. in a separate tube. Thereby, the adhesive may be applied by a user before the association of the opening device to a particular capsule of the kit.

In a preferred embodiment, the capsule opening device further comprises engagement means which are designed to be selectively connectable at least to a portion of the outlet face of the capsule and which are arranged movably with respect to the means for mechanically associating the opening device to the capsule.

Thereby, the engagement means is preferably a suction member designed for separating at least said portion from the outlet face of the capsule upon motion relative to the means for mechanically associating the opening device to the capsule.

Hence, effective deflection of at least said portion of the outlet face of the capsule with regard to the rest of the outlet face is enabled. Thereby, the engagement means may be designed to tear and/or shear a portion of the outlet face with regard to the rest of the outlet face in order to create and opening therein.

In a second aspect, the present invention relates to a capsule opening device for opening a capsule containing nutritional ingredients, preferably infant formula ingredients, the opening device comprising means for mechanically associating the opening device to the capsule, preferably without using tools, the capsule opening device comprising an integrally formed opening member arranged to be operated by a user and designed for being moved relatively to an outlet face of the capsule at least from a first storage position in to a second opening position.

Accordingly, an easily transportable and reusable device is provided which enables a user to open capsules containing nutritional ingredients independent of a stationary system. Hence, a user is enabled to conveniently serve the ingredients provided within such a capsule to a dedicated receiving vessel and thus prepare the nutritional composition upon addition of liquid to the ingredients at any desired location.

In a preferred embodiment, the opening member of the device is designed for selectively being moved within a plane essentially parallel to the outlet face of the capsule. Thereby, the opening member is preferably of essentially plate-shaped form. Accordingly, a very space saving arrangement of the opening device is enabled. The opening device preferably comprises a funnel, movably arranged with respect to the means for mechanically associating the opening device to the capsule, for receiving the nutritional ingredients from the capsule. The funnel is preferably integrally formed with the opening device and arranged to be connectable at least to an outlet face of the capsule. Hence, the user may connect the funnel to the outlet face of the capsule either before or after opening the outlet face by means of the opening member in order to accurately serve the ingredients from the capsule to a dedicated receiving vessel .

Alternatively, the opening member of the device may be integrally formed with the funnel of the device. The funnel of the device may comprise integrally formed dosing means which enable a user to provide a predefined amount of ingredients to an outlet of the funnel and thus to a receiving vessel. Hence, the user may individually choose the dosage respectively the amount of ingredients provided from the capsule to a dedicated receiving vessel

In a third aspect, the present invention relates to a method for opening a capsule containing nutritional ingredients, preferably infant formula ingredients, the capsule having a cup-like base body comprising an opening being closed off by an outlet face, the method comprising the steps of:

- mechanically connecting an opening device to at least a portion of a capsule,

- penetrating the outlet face of the capsule by means of an opening member, and

- creating an aperture in the outlet face of the capsule by selectively moving the opening member with respect to the outlet face.

Accordingly, a method for a rapid and convenient opening of a preferably sealed capsule containing nutritional ingredients is provided.

In a preferred embodiment, the method further comprises the step of moving the opening member along a plane essentially parallel to the outlet face of the capsule. Thereby, the opening member preferably cuts the outlet face of the capsule. Accordingly, a user is enabled to effortlessly create an aperture in the outlet face.

The motion path follow by the opening member is preferably of arc-shaped or essentially semicircular form However, the motion path may be of different form suitable for creating a cut within the outlet face of the capsule such that the ingredients provided within the capsules can be served from the opening defined by the cut .

The method preferably further comprises the step of selectively connecting a suction member to at least a portion of the outlet face of the capsule. Thereby, the suction member is preferably connected to a portion ad acent to a cut created within the outlet face of the capsule. Hence, the suction member may be used to shear respectively tear a portion of the outlet face. Thereby, the tearing respectively shearing by means of the suction member may be assisted by the cut created within the outlet face.

After providing the nutritional ingredients from the capsule to a dedicated receiving vessel, a user may provide cold or hot liquid to the vessel in order to reconstitute the nutritional composition. Thereby, the ingredients are preferably reconstituted with water. However, the ingredients may as well be reconstituted with liquid selected from milk, juices, etc. Hence, a reconstitution of the nutritional composition is enabled independent of a dedicated beverage preparation machine.

Detailed description of the figures Figures la to If relate to schematic drawings of a capsule 10 and the capsule opening device 1 of the kit according to the present invention. In particular, the figures la to If relate to different steps during interaction of the capsule 10 and the opening device 1 during operation by a user.

Figure la shows the capsule 10 and the opening device 1 in their non-associated state. As can be seen in the figures, the capsule 10 generally comprises a body portion 10b which is preferably cup-shaped and which comprises at least an aperture 11 at a top portion of the body portion 10b. The capsule further comprises a flange ^¬ like rim portion 10a surrounding the aperture 11 to which a top membrane or foil 10c is sealed. Thereby, the top membrane or foil 10c essentially forms the outlet face of the capsule. It should be noted that the membrane 10c may be simply liquid impervious or, most preferably, liquid and gas impervious. In particular, the membrane can be a multi layer comprising a gas value such as EVOH and/or aluminum. Preferably, the membrane 10c is made of thin polymer and/or aluminum.

Although referred to as an outlet face due to its function of serving the nutritional ingredients after opening of the membrane 10c, said outlet face may as well be referred to as inlet face due to its function to enable the injection of liquid by means of a dedicated preparation machine into which the capsule is insertable. At a bottom portion of the cup-shaped body portion 10b of the capsule 10, and thus, opposite to the membrane 10c, an outlet 30 (see figure 4e) for the release of the liquid nutritional composition/product from the capsule may be formed. Thereby, the outlet 30 may comprise one or several openings for streaming of the liquid composition towards a dedicated receiving vessel when the capsule is used in conjunction with a dedicated beverage production machine. It should be noted that the capsule 10 is generally adapted for being used in conjunction with such a beverage production machine.

At an upper side of the body portion 10b, an extension portion 12 is formed which is preferably designed for receiving filter means for filtering liquid supplied to the capsule 10 by means of a dedicated beverage production machine.

In the cup-shaped portion 10b of the capsule a compartment for containing nutritional ingredients 23 (see figure 5b) is preferably formed by the bottom and sidewall of the cup-shaped body portion 10b. Thereby, the volume of the compartment may vary depending on volume of liquid to be injected into the capsule. The capsule opening device 1 of the kit is of essential plate-like shape and comprises connection means 3 integrally formed with the body of the opening device 1. Thereby, the connection means 3 is preferably a connection grove formed in an outer rim portion la of the opening device 1 and having a U-shaped cross section which is designed to interact with the rim portion 10a of the capsule 10. Thereby, the connection grove 3 is opened to at least one side of the capsule opening device 1 such that the opening device 1 can be slidably attached to the rim portion 10a of the capsule 10 as indicated by arrow Al in figure la.

The capsule opening device 1 is further equipped with an integrally formed opening member 13 supported by the body of the opening device 1 and rotationally moveable around a central axis Z thereof.

The opening member 13 is preferably arranged at an upper surface lb of the opening device 1 which is arranged opposite to a lower surface lc thereof, to which the capsule 10 is connected in an associated state of the capsule 10 and the opening device of the kit as shown in figure lb. The opening member 13 preferably comprises handling means 14 which enable a user to operate the opening member 13. The handling means 14 is preferably a button- shaped member integrally formed with the opening member 13 which is large enough to enable a handling of the opening member 13 by means of a finger tip of a user.

At an outer portion of the opening member 13 a cutting blade 2 (see figure 2c and 4c) is attached which extends from the upper surface lb on which the handling means 14 are moveably arranged to the lower surface lc of the opening device 1.

As shown in the figures la to If, the cutting blade 2 is movably arranged within a guiding support groove 15 extending from the upper surface lb to the lower surface lc of the capsule opening device 1.

The support grove 15 is preferably of essentially arc- shaped from. However, the support groove may as well be of semi-circular form for example.

A user is thus enabled to move the opening member 13 along a motion path of the cutting blade 2 guided by the support groove 15. Thereby, the cutting blade 2 preferably comprises at least a storage position A and an opening position B. More preferably, the motion path preferably comprises two storage positions A, C which are provided at the respective ends of the motion path of the cutting blade 2 (see figure le) .

As indicated in figure 2a and 2b, when the cutting blade 2 is in its storage position A, respectively second storage position C, the cutting plate 2 is not protruding from the lower face lc of the capsule opening device 1 (see figure 2b). This is due to a support respectively storage member 16 which is preferably integrally formed with the upper surface of the opening device 1 and which protrudes from said upper surface lb such that the cutting blade 2 does not protrude from the lower surface lc of the opening device 1. Hence, in said storage position, a user is effectively prevented from cutting himself during handling of the opening device 1. When the opening member 13 is moved along its motion path, as indicated by error A2 in figure lb to Id, the cutting plate 2 is moved essentially orthogonal to the outlet face 10c of the capsule 10 as the opening member 13 is guided from supporting position at the storage means 16 by means of a ramp 16a to the upper surface lb of the opening device 1. Thereby, the blade 2 is continuously protruding to a further extend from the lower face lc of the capsule opening device 1 such that when a capsule 10 is associated to the opening device 1 as shown in figure lb, the blade 2 is made to pierce respectively to cut into the upper face 10c of the capsule 10.

During the further movement of the cutting member 13 along its motion path as indicated in figure lc, an arc- shaped cut 17 (see figure le) is produced in the outlet face 10c of the capsule 10. At the end of the motion path followed by the cutting member 13, the cutting blade 2 is brought from a opening position B to a second storage position C by means of a second storage or support member 16 formed at the end of the guiding groove 15. Thereby, in order to enable a smooth disconnection of the blade 2 from the outlet face 10c of the capsule 10, a ramp member 16a is provided between the support grove 14 and the port member 16. Thus, the cutting blade is continuously retracted from the outlet face 10c of the capsule 1 due to said ramp member 16.

It should be noted that in order to enable such a relative movement between the upper surface lb of the opening device 1 and the opening member 13, the opening member 13 is to be at least partially flexible with respect to the upper surface lb of the device 1.

During the movement of the cutting blade 2 within the support groove 15, the cutting blade respectively the cutting member 13 is preferably moved along a motion path essentially parallel to a plane P (see figure If) which is essentially parallel arranged to the lower surface lc of the opening device 1 and thus, essentially parallel to the outlet face 10c of the capsule 10 when the capsule 10 is in its associated state to the opening device 1. Accordingly, a very compact design of the opening device 1 is provided. As shown in figure le, after the cutting member 13 is brought in storage position C, the user is enabled to easily detach the opening device 1 from the capsule 10 as indicated by arrow A3. Thereby, in order to enable a facilitated connection and disconnection of the capsule 10 and the opening device 1, the opening device comprises a recess 21 from which the circumferential rim portion 10a of the capsule 10 is at least partially protruding such that a user is enabled to grip the protruding rim portion 10a of the capsule 10 with his fingers in order to connect respectively disconnect the capsule 10 to the opening device 1.

Further, since an arc-shaped cut 17 has now been produced in the outlet face 10c of the capsule 10, a user is enabled to open the capsule 10 by folding respectively bending the outlet face 10c around an edge 18 between the respective ends of the cut 17. Since an opening 24 is now produced in the outlet face 10c of the capsule 10, a user is now enabled to serve the ingredients provide within the capsule body portion 10b to a dedicated glass or receiving vessel .

Figures 3a to 3f relate to another preferred embodiment of the kit according to the present invention, wherein the opening device 1 comprises a funnel member 5. As can be seen in figures 3a to 3f, the opening device 1 comprises an upper portion 26 which is essentially formed of the plate-like opening member 1 according to the first embodiment as described with reference to figures la to If, and a second lower portion 27 which comprises the funnel member 5. Thereby the first upper portion 26 and the second lower portion 27 are preferably attached by joint member 19 which enables a relative motion of the upper opening member 26 and the lower funnel 5. The opening member 1 according to said embodiment can preferably assume at least two positions of the first upper portion 26 and the second lower portion 27. Thereby, figure 3a refers to a storage position of the opening member 1 in which the plate-like upper portion 26 is arranged on top of the lower portion 27, thereby closing off the upper aperture 5a of the funnel 5.

Upon movement about the pivot axis (arrow A3) of the joint member 19, the upper portion 26 may be brought from the storage position into a second capsule opening position as indicated in figure 3b. Thereby, a lower face lc of the upper portion 26 is brought to a position offset to the lower portion 27 comprising the funnel member 5 such that a capsule 10 may be connected to the dedicated connection means 3 provided at the lower surface lc of the opening device 1 (arrow A4 ) . This essentially corresponds to the association of the capsule 10 and the opening device 1 as described with reference to figures la to If.

As indicated in figures 3d and 3e, in the state in which the capsule 10 is associated to the opening device, the opening member 13 is operated by a user in order to cut a predefined cut 17 corresponding to the support grove 14 of the opening device 1 into the outlet face 10c of the capsule 10 as indicated by arrow A5.

After the capsule 10 is detached from the connection means 3 of the capsule opening device 1, ingredients 23 may be served from the capsule 10 to the upper opening 5a of the funnel 5 (arrow A6 ) such that the ingredients 23 are funneled down to the lower opening 5b from which a dosage to a dedicated glass or receiving vessel is enabled. Thereby, the funnel 5 may comprise integrally formed dosing means (not shown) which enable a user to serve a predefined amount of ingredients from the lower opening 5b of the funnel 5. The dosage means may for example comprise a manually operable valve member. Figures 4a to 4e relate to another preferred embodiment of the kit according to the present invention, wherein the capsule opening means 1 comprise funnel means 5 having an integrally formed opening member 2. Thereby, as can be particularly seen in figures 4a to 4c, the opening device 1 comprises a first and a second enclosing member 20a, 20b.

The first enclosing member 20a is pivotally connected to the second enclosing member 20b by means of a joint 22. The first enclosing member 20a comprises positioning means 21 correspondingly shaped to the rim portion 10c of the capsule 10 and suitable for interacting with said rim portion 10c in order to support a capsule 10 placed therein. When being brought from their engagement position as shown in figure 4a to the capsule insertion position as shown in figure 4b, a capsule 10 may be provided to the first engagement member 20a of the opening device as shown in figures 4b and 4c. After the capsule 10 has been provided to the first engagement member 20a, the opening device 1 is brought to its capsule engagement position as shown in figure 4d.

Connection means 3a which are preferably provided at a portion of the opening device 1 opposite to the joint 22, enable a stable connection between the first and second engagement members 20a, 20b. Thereby, the connection means 3a is preferably a reclosable snatch member suitable for fixedly engaging the first and second engagement members 20a, 20b.

In its engagement position as shown in figure 4d, a blade protruding from an inner side of the funnel 5 integrally formed with the second engagement member 20b is pinched respectively cut into the outlet face 10c of the capsule 10. Then, a user will rotate the funnel member 5 with respect to the first and second engagement members 20a, 20b and thus with respect to the outlet face 10c of the capsule 10 such that a circular opening is cut into the outlet face 10c of the capsule 10 (see arrows A7 ) . For this purpose, the funnel 5 is preferably rotatable supported by means of the second enclosing member 20b. For facilitating the rotational movement of the funnel 5 with respect to the first and second engagement members 20a, 20b, the funnel preferably comprises circumferentially arranged recesses 28 for supporting the fingers of the user during rotation.

In a further step as depicted in figure 4e, a user may rotate the opening device 1 such that the funnel member 5 is facing with its outlet opening 5b downwards, thereby releasing the ingredients from the capsule 10 by means of the circular opening created in the outlet face 10c. Hence, the ingredients contained within the capsule 10 may be easily and conveniently provided by means of the funnel member 5 towards a provided receptacle (see arrow A8) .

Figures 5a and 5b relate to another preferred embodiment at the opening device 1 of the present invention, wherein the capsule opening device 1 additionally comprises engagement means 4 suitable for interacting at least with a portion lOd of the outlet face 10c of the capsule 10.

In this embodiment, the capsule 10 is placed into dedicated positioning means 21 of the first engagement member 20a (see arrow 9) . Then, the second engagement member 20b is brought into a capsule insertion position (see arrow A10) corresponding to the position as shown in figure 4c. Thereby, a suction member 4 provided at an lower surface of the engagement member 20b interacts with a portion lOd of the outlet phase 10c of the capsule 10 such that the portion lOd is sucked towards the suction member 4. Hence, during opening of the opening device 1 respectively during separation of the first and second engagement member 20a, 20b, the portion lOd of the outlet face 10c stays sucked towards that suction member 4, thereby rupturing the portion lOd of the outlet face 10c in order to create an opening 24 therein.

Before the separation of the first and second engagement members 20a, 20b the cutting member 2 may be used in order to create a cut 17 in the outlet face of the capsule 10. Hence, after separation of the first and second engagement members 20a, 20b, a very accurate large aperture is provided at the outlet face 10c, whereby the portion lOd is bent about a fold line 18 present between the ending of the cut 17.

Thus, a convenient serving of the ingredients 23 contained within the body portion 10b of the capsule 10 is enabled. After serving of the ingredients 23 from the capsule, the user may easily detach the portion lOd from the suction member 4 and release the capsule 10 from the positioning means 21.

Figures 6a to 6g relate to another preferred embodiment of the kit according to the present invention similar to the embodiment according to figures 4a to 4e and wherein the capsule opening means 1 further comprise a cover member 31.

The cover member 31 is preferably arranged to close-off the capsule opening means 1 in its storage position as shown in figure 1. The cover member 31 thus comprises a lid portion 31b being preferably of complementary shape to the funnel member 5 respectively the enclosing member 20a, such that an effective protection of the interior of the opening means 1 is obtained by the cover member 31 in its storage position.

The cover member 31 further comprises a lever portion 31a integrally formed with the cover member 31. Thereby, the lever portion 31a is preferably protruding from a portion of the cover member 31 away from the lid portion 31b. The lever portion 31a is preferably a hook-like portion arranged about a joint 32 of the cover member 31. Thereby, the hook-like portion is preferably complementary formed to a body portion 10b and/or to a portion of the outlet face 10c of the capsule 10 with which it is to interact upon movement of the cover member 31.

The cover member 31 is preferably connected to the capsule opening means 1 by means of the joint 32. Thereby, the joint 32 is arranged to rotatably connect the cover member 31 to at least one of the first and second enclosing members 20a, 20b. The joint 32 is preferably arranged in parallel and offset to the joint 22 connecting the first and the second enclosing member 20a, 20b.

As shown in figures 6b to 6f, the cover member 31 is brought into an opening position (arrow A9) by rotation about joint 31. Subsequently, the first and second enclosing members 20a, 20b are separated by a rotation about joint 22 (arrow A10) . The capsule 10 is then placed into the opening means 1 before the first and second enclosing members are brought into their closing position again (arrow All) such that the protruding blade 2 interacts with the outlet face 10c of the capsule 10, e.g pierces the outlet face 10c. Thereby, the first and second enclosing members 20a, 20b are preferably engaged by means of provided connection means 3a.

The opening means 1 are then flipped upside-down (arrow A12) such that the funnel 5 is facing downwards. In a next step, the funnel 5 is rotated by a user (arrow A13) such that the blade 2 creates an aperture within the outlet face 10c of the capsule 10. As shown in figure 6g, the cover member 31 is then rotated by a user about joint 32 such that the lever portion 31a of the cover member 31 interacts with at least an outer portion of the capsule 10. In a preferred embodiment as shown in figure 6g, the lever portion 31a is designed to interact upon movement about joint 32 with a portion of the capsule outlet face 10c and/or a portion of the capsule arranged in vicinity of the outlet face 10c, such as e.g. the extension portion 12 formed at an upper side of the body portion 10b.

Hence, a force is applied onto the capsule body 10b and/or the outlet face 10c by means of the interaction of the lever portion 31a with the portion of the capsule 10 which leads to an effective ejection of the composition from the capsule 10 towards the funnel 5 from which the composition may then be provided (arrow A15) to e.g. a receptacle (not shown) . Thereby, the force applied by the lever portion 31a is preferably a compressive and/or shearing force (arrow A14) which leads to a widening of the aperture created in the outlet face 10c by means of the blade 2. Thus, the exit of the composition from the capsule 10 towards the funnel 5 is essentially facilitated.

It is to be noted that the lever portion 31a may be of any particular shape suitable for providing a dedicated force onto at least a portion of the capsule 10 upon rotation of the cover member 31 about joint 32.
