CROSS REFERENCE TO RELATED APPLICATIONS/INCORPORATION BY REFERENCE STATEMENT 
       [0001]    This application is a US national stage application filed under 35 USC §371 of International Application No. PCT/EP2014/054444, filed Mar. 7, 2014; which claims benefit of EP Application No. 13158244.7, filed Mar. 7, 2013. The entire contents of the above-referenced applications are hereby expressly incorporated herein by reference. 
     
    
     BACKGROUND 
       [0002]    The presently disclosed and/or claimed inventive concept(s) relates to a device for dispensing capsules containing beverage ingredients from a storage or supply means holding a plurality of capsules. In particular, the presently disclosed and/or claimed inventive concept(s) relates to a device and a method enabling the dispensing of capsules to a discharge outlet while maintaining a predefined atmospheric environment within a portion of the device and/or within the supply means. 
         [0003]    The preparation of drinks such as coffee or tea from capsules containing a predetermined serving of beverage ingredients is well known in the prior art. Capsules have the advantage of facilitating the operations of preparing the drink, ensuring relatively clean preparation and controlling the amount and quality of the prepared product. 
         [0004]    The principle of extracting from a capsule includes the steps of (i) enclosing the capsule in a pressure-resistant enclosure, (ii) piercing one of the faces of the capsule, generally by means of one or more spike(s) or blade(s) situated in a part comprising a water inlet or injection device, (iii) introducing a quantity of water (such as, but not limited to, hot water) into the capsule to create a pressurized environment therein to produce the liquid beverage extract, and finally (iv) releasing the liquid beverage extract through the opposite face of the capsule, which opens under the internal pressure created inside the capsule, e.g. by means of being urged against dedicated opening means. 
         [0005]    In most commercially available extraction devices, the capsules are loaded manually or individually into the extraction capsule holder, such as by a bayonet-engagement capsule holder of the type used e.g. in traditional espresso machines. 
         [0006]    There are also devices available which are designed for feeding the capsules from a capsule magazine to the device in order to provide a more automated arrangement and in particular an automatic delivery of the capsules to the consumer or to a beverage preparation device. 
         [0007]    US 2005/0000366A for example proposes a device for feeding capsules containing a substance to be extracted in an extraction system under pressure for the preparation of a drink. The device includes a supply of capsules arranged in several series, and a mechanism for individually unloading one capsule directly into a reception part of the beverage extraction device, which is arranged beneath the unloading mechanism in such a way as to allow the direct descent of the released capsule into the reception part. Further, the device comprises a structure for opening the capsule and for releasing the liquid extract therefrom. 
         [0008]    It is known that the quality of the resulting beverage strongly depends on the ingredients contained in the capsule. Thereby, in order to provide a reproducible quality of the resulting beverages, preservation of the original beverage ingredients within the capsules is an important factor. In particular, any contact of the beverage ingredients with air and specifically with oxygen results in undesired oxidation processes of the ingredients and is thus to be prevented. 
         [0009]    Preservation of the beverage ingredients within capsules arranged in the available automated dispensing apparatus as indicated above is usually obtained by providing the individual capsule with an outer enclosing material comprising oxygen-barrier properties. 
         [0010]    There exists however the need to use such a dispensing apparatus also in combination with capsules made from e.g. paper, cardboard or biological degradable material which are essentially gas-permeable and thus do not comprise such oxygen barrier properties. 
         [0011]    In order to provide preservation of such capsules being made of a gas-permeable material, a secondary packaging comprising barrier properties is generally provided in which a plurality of such capsules in enclosed. This results in the drawback that after opening of the secondary packaging, no further preservation of the ingredients provided within the individual capsules is obtainable. 
         [0012]    Therefore, a solution is sought after which enables the use of such capsules made from gas-permeable material with a capsule dispensing respectively feeding device while maintaining preservation of the ingredients contained in the individual capsules. 
         [0013]    The presently disclosed and/or claimed inventive concept(s) aims at overcoming the above-outlined problems of the prior art. Furthermore, the presently disclosed and/or claimed inventive concept(s) aims at providing a solution to further problems identified in the description.

     DETAILED DESCRIPTION 
       [0023]    In a first aspect, the presently disclosed and/or claimed inventive concept(s) relates to a device for controlled dispensing of capsules containing beverage ingredients, the device comprising receiving means designed to be selectively connectable to a storage means, for example a packaging, comprising a plurality of capsules to be dispensed by the device, outlet means, such as (but not limited to) a discharge outlet, for dispensing at least one of the plurality of capsules received by the receiving means, and barrier means respectively a distribution area, arranged within a capsule transport path from the receiving means to the outlet means. In certain, non-limiting embodiments, the distribution area is designed to individually discharge a capsule from the packaging under a controlled atmospheric environment. In certain, non-limiting embodiments, the distribution area is designed for preventing transport and/or ingress of at least one of water vapour and oxygen gas from the discharge outlet to the receiving means. 
         [0024]    In a particular, non-limiting embodiment, the barrier means respectively the distribution area is designed to provide a selectively openable water vapour and/or oxygen-barrier between the receiving means and the discharge outlet. 
         [0025]    In certain, non-limiting embodiments, the barrier means respectively the distribution area of the device is designed for controlling an atmospheric environment within at least a portion of the distribution area. The distribution area may as well be designed for controlling an atmospheric environment within the packaging connected to the receiving means of the device. 
         [0026]    The device thus enables the dispensing of capsules from the packaging while maintaining an oxygen-barrier and/or water vapour barrier between the discharge outlet of the device and the receiving means to which a predefined packaging for capsules is selectively connectable. Therefore, the ingress of air and/or water vapour and in particular of oxygen through the discharge outlet into a predefined portion of the device and/or into the packaging during the dispense process is prevented. 
         [0027]    Accordingly, the device provides an enhanced storage environment for the capsules in the capsule dispensing device and/or in a predefined capsule packaging connected to the receiving means with respect to the preservation of the beverage ingredients contained in the capsules. Thereby, the device eliminates the need of providing the individual capsules with a material having gas-barrier properties. 
         [0028]    In certain, non-limiting embodiments, the barrier means (distribution area) of the device is designed for transport of a capsule from the receiving means to the discharge outlet of the device. More particularly (but not by way of limitation), the barrier means (distribution area) is designed to enable the provision of at least one capsule per dispense process respectively one capsule at a time from the receiving means to the discharge outlet. 
         [0029]    In certain, non-limiting embodiments, the transport of the capsule from the receiving means to the discharge outlet is carried out by dedicated capsule transport means. Thereby, in certain, non-limiting embodiments, the transport means provide a capsule transport path through the device and/or through the barrier means (distribution area). In certain, non-limiting embodiments, the transport of the capsule is supported by gravity. In certain, non-limiting embodiments, the transport path of the capsule from the receiving means to the discharge outlet is arranged within the device in an essentially vertical direction. 
         [0030]    The transport means may comprise support means, a funnel or essentially vertically arranged conduct or tubing. The transport means may however also comprise a slide or slanted surface designed to enable a guidance of the respective capsule in a desired direction through the barrier means (distribution area) supported by means of gravity. 
         [0031]    The barrier means (distribution area) is designed for controlling an atmospheric environment within at least a portion or predefined enclosure of the barrier means (distribution area). Thereby, the controlling of the atmospheric environment within said portion or enclosure of the barrier means (distribution area) may be carried out continuously and/or triggered by a capsule dispense operation of the device upon e.g. a user request. 
         [0032]    The barrier means (distribution area) may further be designed for controlling an atmospheric environment within at least a second portion or predefined second enclosure of the barrier means (distribution area). Thereby, the controlling of the atmospheric environment within said second portion or enclosure of the barrier means (distribution means) may be carried out in accordance with the control of the atmospheric environment in the first portion or predefined enclosure or may differ therefrom. 
         [0033]    It is noted that the term “atmospheric environment” respectively “controlled atmospheric environment” refers to a gaseous environment within a predefined enclosure such as e.g. a predefined portion of the distribution means respectively to a controlled gaseous environment present in such enclosure. Such portion of the distribution means may be dedicated chambers in which the atmospheric environment is present or controlled. Thereby, in certain, non-limiting embodiments, the (controlled) atmospheric environment differs from the atmospheric air in its composition. In particular, the oxygen content within the (controlled) atmospheric environment is reduced compared to the oxygen content in the atmospheric air. 
         [0034]    In a particular, non-limiting embodiment, the barrier means (distribution area) comprises a first receiving chamber connected to the receiving means and a second dispensing chamber connected to the discharge outlet for selectively dispensing at least one capsule therefrom. 
         [0035]    In certain, non-limiting embodiments, the barrier means (distribution area) comprises at least a first and a second locking means, each of which is designed to be selectively transferable from an open state to a closed state, independent from each other. 
         [0036]    In the open state of the respective first or second locking means, the transfer of a capsule from a first side to a second side of the respective locking means is enabled. The respective locking means provide in their open state an aperture large enough for at least one capsule to be transported from a first side of the respective locking means to a second side thereof. In the closed state of the respective first or second locking means, the respective first or second locking means provide oxygen-barrier and/or water vapour barrier properties from a first side of the respective first or second locking means to a second side of the respective first or second locking means. The at least first and second locking means are arranged to enclose a predefined portion of the barrier means (distribution area). In a particular, non-limiting embodiment, the at least first and second locking means enclose at least the receiving chamber of the device and/or the dispensing chamber. 
         [0037]    In a particular, non-limiting embodiment, the respective locking means provide a selectively openable barrier that connects the receiving chamber with the dispensing chamber of the device. The second locking means provides a selectively openable barrier that connects the dispensing chamber with the discharge outlet of the device. 
         [0038]    Accordingly, the dispensing chamber provided within a capsule transport path from the receiving means to the discharge outlet of the device is enclosed by the respective first and second locking means. Thereby, in certain, non-limiting embodiments, the dispensing chamber is sized such that a single capsule is encompassed by the chamber. The dispensing and/or receiving chamber may however also be sized to encompass at least two or three capsules therein. 
         [0039]    In certain, non-limiting embodiments, the locking means are selectively slidable doors, plates, drawers or the like. In certain, non-limiting embodiments, the locking means are arranged to be moveable in a direction essentially perpendicular to the capsule transport path from the receiving means to the discharge outlet of the device, and thus to be movable essentially perpendicular to the capsule transport path. 
         [0040]    In certain, non-limiting embodiments, the at least first and second locking means are arranged in series within an elongated support member or capsule transport means such as e.g. a tube or funnel member, in order to selectively enclose a predefined portion or space within the support member respectively transport means. 
         [0041]    In certain, non-limiting embodiments, the locking means are arranged within guiding means provided in the transport means of the device and designed for guiding the movement of the locking means. The guiding means may comprise sealing means such as to seal respective chambers of the barrier means (distribution area) in the closed state of the respective locking means. 
         [0042]    The device may additionally comprise further locking means arranged in series with the first and second locking means such as to provide additional oxygen barriers and/or water vapour barriers within the capsule transport path from the receiving means to the discharge outlet. 
         [0043]    In certain, non-limiting embodiments, the device further comprises atmospheric control means that are connected to the capsule transport path from the receiving means to the discharge outlet. The atmospheric control means may comprise a control unit which is connected to a predefined portion or enclosure of the barrier means (distribution area) in order to control or adjust the atmospheric environment within said enclosure.

The atmospheric control means may as well be connected to the receiving means and the packaging when connected to the device. Further, the atmospheric control means may as well be connected to the dispensing chamber of the device. 
         [0045]    The atmospheric control means may comprise flushing means designed to enable a flushing of the predefined portion, enclosure or chamber with a gaseous medium of predefined composition. In certain, non-limiting embodiments, the flushing means comprise an injection valve and a relief valve. 
         [0046]    The atmospheric control means may be designed for enabling flushing the predefined portion, enclosure or chamber of the device to which they are connected with inert gas such as to remove any oxygen content therefrom. In particular, an excess of inert gas is provided to the predefined portion, enclosure or chamber such that any remaining oxygen gas is expelled through the relief valve. 
         [0047]    In certain, non-limiting embodiments, the inert gas used for flushing is nitrogen gas. However, any other inert gas may be utilized. In certain, non-limiting embodiments, a supply container for providing inert gas is selectively connectable to dedicated receiving means of the device. The supply container may thus be selectively connected to the atmospheric control means of the device. 
         [0048]    The atmospheric control means may further comprise a sensor arranged within the respective predefined portion, enclosure or chamber of the device such as to detect the presence of oxygen. 
         [0049]    It is noted that, in certain, non-limiting embodiments, the device according to the presently disclosed and/or claimed inventive concept(s) comprises a dedicated capsule secondary packaging for holding a plurality of capsules therein and designed for being selectively connectable to the receiving means of the device. 
         [0050]    It is noted that the term “plurality” of capsules” is to be understood as referring to at least two individual capsules arranged within the packaging. In a particular, non-limiting embodiment, 3 to 20 capsules are arranged within the packaging. 
         [0051]    By means of the device according to the presently disclosed and/or claimed inventive concept(s), preservation of the beverage ingredients held within the capsules stored in the connected packaging or within a predefined portion of the barrier means (distribution area) is enhanced, irrespective of the material used for the individual capsules. Accordingly, even ingredients held within capsules made from gas-permeable material such as cardboard or biodegradable material may be protected from reaction with oxygen during storage. 
         [0052]    In a further aspect, the presently disclosed and/or claimed inventive concept(s) relates to a beverage preparation machine for preparing a beverage upon injection of liquid into a beverage ingredients containing capsule. The beverage preparation machine comprises a device for controlled dispensing as described above. 
         [0053]    In certain, non-limiting embodiments, the dispensing device is arranged in such a way with respect to a brewing chamber of the beverage preparation machine, such that the capsule may be provided directly from a discharge outlet of the dispensing device into the brewing chamber of the beverage preparation machine. 
         [0054]    In a further aspect, the presently disclosed and/or claimed inventive concept(s) relates to a packaging for holding a plurality of ingredients containing capsules. 
         [0055]    As outlined above, the term “plurality” of capsules” in this regard is to be understood as referring to at least two individual capsules arranged within the packaging. In a particular, non-limiting embodiment,  3  to  20  capsules are arranged within the packaging. 
         [0056]    In certain, non-limiting embodiments, the packaging is made from material comprising gas (oxygen and/or water vapour) barrier properties such as e.g. polyethylene, polypropylene, EVOH, a multilayer-structure comprising oxygen barrier properties or aluminium. 
         [0057]    In certain, non-limiting embodiments, the packaging comprises at least one outlet aperture designed for being connected to receiving means of a dispensing device for controlled dispensing of capsules held by the packaging, wherein the outlet aperture is hermetically sealed with a closure material, such as (but not limited to) a closure member, comprising oxygen-barrier properties. 
         [0058]    In certain, non-limiting embodiments, the packaging is designed to interact with dedicated receiving means of a capsule dispensing device as described above, in order to open the closure member at the outlet aperture upon insertion and/or connection of the packaging with the receiving means provided at the dispensing device. 
         [0059]    The receiving means of the dispensing device may comprise specifically designed opening members which are adapted to open and seal the outlet aperture of the packaging when connecting the packaging to the receiving means, such as to prevent the ingress of oxygen into the packaging. 
         [0060]    In a particular, non-limiting embodiment, the closure member of the packaging for closing the at least one outlet aperture is formed by at least a portion of a first capsule being arranged in vicinity of the outlet aperture of the packaging. 
         [0061]    In a further aspect, the presently disclosed and/or claimed inventive concept(s) relates to a method for controlled dispensing of beverage ingredients containing capsule from storage means, in particular a packaging, in which a predefined atmospheric environment is present, comprising the steps of:
       transferring a capsule from the storage means, such as (but not limited to) a packaging, to a receiving chamber or a dispensing chamber,   transferring the capsule from the receiving chamber or the dispensing chamber to a discharge outlet,   controlling an atmospheric environment within the receiving chamber and/or the dispensing chamber such that transport and/or ingress of at least one of oxygen gas and water vapour from the discharge outlet to the storage means is prevented.       
 
         [0065]    In certain, non-limiting embodiments, the method further comprises the step of selectively opening and closing barrier means such as oxygen and/or water vapour barrier means, arranged in the transfer path of the capsule between the storage means, i.e. the packaging, the receiving chamber and/or the dispensing chamber and the discharge outlet in a predefined pattern. 
         [0066]    In certain, non-limiting embodiments, the step of controlling an atmospheric environment with the receiving chamber and/or the discharge chamber is carried out continuously, before, and/or after opening a transfer path of the capsule between the storage means and the receiving chamber. 
         [0067]    Furthermore, the controlling of the atmospheric environment with the receiving chamber and/or the dispensing chamber may further comprise the step of detecting an oxygen content within the receiving chamber and/or the dispensing chamber, e.g. by means of a dedicated sensor, and adjusting the atmospheric environment within the receiving chamber and/or the dispensing chamber according to predefined values depend on the detected oxygen content. 
         [0068]    The step of controlling the atmospheric environment may comprise the removal and/or supply of gaseous media from/to the receiving chamber and/or the dispensing chamber. 
         [0069]    In a particular, non-limiting embodiment, the step of controlling an atmospheric environment comprises the step of flushing the receiving chamber and/or the dispensing chamber with inert gas, such as (but not limited to) nitrogen, such as to remove any oxygen therefrom. 
         [0070]    Turning now to the Drawings,  FIG. 1  shows a schematic drawing of a particular, non-limiting embodiment of a capsule dispensing device  50  according to the presently disclosed and/or claimed inventive concept(s).

In particular, in case a capsule  10  was held within the dispensing chamber B and the locking means  7   b  are brought into the shown open position, the capsule  10  will fall through the discharge outlet  3  arranged below the dispensing chamber B. 
         [0086]    The device further comprises atmospheric control means  15  coupled to the barrier means (distribution area)  5 . Thereby, in certain, non-limiting embodiments, the atmospheric control means  15  are coupled to the receiving chamber A and/or dispensing chamber B such as to enable the control of the atmospheric environment enclosed therein. 
         [0087]    In certain, non-limiting embodiments, the atmospheric control means  15  comprise a valve means  40   a,   40   b  (see  FIG. 7   a ) which are designed for provision of inert gas such as e.g. nitrogen gas to at least the reviving chamber A and/or dispensing chamber B of the barrier means  5  (distribution area). Thereby, the control means  15  are connected to a supply of inert gas such as e.g. a gas tank  16  selectively connectable to the device  50  (see schematic drawing  FIGS. 2 and 5 ). 
         [0088]    In certain, non-limiting embodiments, the control means  15  comprise a pump ( 15   a ) arranged between the supply  16  and the barrier means  5  (distribution area) in order to selectively provide inert gas to the barrier means  5  (distribution area). 
         [0089]    The control means  15  may as well comprise at least one relief valve  40   b  (see  FIG. 7   a ) connected to the barrier means (distribution area)  5  in order to enable any excess gas to leave a predefined portion of the barrier means (distribution area)  5 . In particular, the relief valve may be arranged within the receiving chamber A and/or the receiving chamber B. 
         [0090]    In certain, non-limiting embodiments, the control means  15  are designed to enable a flushing of the receiving chamber A and/or of the dispensing chamber B by means of inert gas such as nitrogen. 
         [0091]    Thereby, at least the receiving chamber A as well as the dispensing chamber B may be equipped with input valves  40   a  such as to provide inert gas into the respective chamber A,B. Furthermore, at least the receiving chamber A may be equipped with a relief valve  40   b  such as to enable a flushing of receiving chamber A and/or the packaging connected thereto with inert gas. In addition, the dispensing chamber B may as well be equipped with a relief valve  40   b  such as to enable the provision of excess inert gas to the dispensing chamber B and remove any residual oxygen gas therefrom by means of the relief valve. 
         [0092]    In certain, non-limiting embodiments, the tubular member  6  and the locking means  7   a,   7   b  which enclose the respective chambers A,B are made from a material which is essentially gas impermeable, such as e.g. aluminium. 
         [0093]    The tubular member  6  may further comprise dedicated sealing means which close the respective chamber A and/or B in an essentially gas-impermeable manner at least in the closed state of the respective locking means  7   a,   7   b.    
         [0094]    In particular, the receiving chamber A which is selectively separable from the dispensing chamber B is designed such that any ingress of gas such as e.g. oxygen gas and/or water vapour is prevented in the closed state of the first locking means  7   a.    
         [0095]    In certain, non-limiting embodiments, the receiving chamber A is connected to the receiving means  1  of the device in direct fluid communication, i.e. without any additional barrier means respectively locking means arranged therebetween. Alternatively, there may be additional locking means arranged between the receiving means  1  and the receiving chamber A such as to provide selectively openable oxygen and/or water vapour barrier means between these two parts of the device  50 . 
         [0096]    A particular, non-limiting embodiment of the discharge process is explained in the following with regards to  FIGS. 1 to 3 , as well as the detailed  FIGS. 7   a  to  7   d : A packaging  20  is connected to the receiving means  1  with the aid of engagement means such as e.g. a screw connection or a bayonet-type connection  1   a,   1   b.  Thereby, the packaging  20  may initially be kept closed, i.e. the packaging  20  which itself is made of a material with oxygen barrier properties may not immediately be opened upon being connected with the receiving means  1 . 
         [0097]    For sealing the interior of the packaging  20  when connected to the device, the receiving means  1  may comprise a sealing member, such as at least one O-ring  30 . When the packaging  20  is connected to the receiving means, the O-ring  30  is urged against an outer surface of the packaging  20  (see  FIG. 7   a ). 
         [0098]    In a next step, the receiving chamber A which is connected to the receiving means  1  and which is separated from the dispensing chamber B by means of closed locking means  7   a  may be flushed with inert gas such as nitrogen to remove any excess oxygen from the receiving chamber A. Accordingly, a predefined atmospheric environment is established in the receiving chamber A only containing inert gas such as nitrogen. As a next step, opening means arranged at or in vicinity of the receiving means  1  may be activated in order to open the packaging  20  connected to the receiving means  1 . Upon opening of the packaging  20 , in certain, non-limiting embodiments, the capsules contained therein are urged downwards under the effect of gravity such that at least one capsule is placed within the receiving chamber A. 
         [0099]    As an alternative to the above-indicated connection process of the packaging  20  to the device  50 , the packaging  20  may be designed to be opened upon connection with the device  50  e.g. by means of a bayonet-type connection mechanism  1   a,   1   b.  Thereby, after connecting the packaging  20  to the device, the atmospheric control means  15  connected to at least receiving chamber A may be activated such as to flush the receiving chamber A and the packaging  20  by means of excess inert gas such as to remove any oxygen from the receiving chamber A and the packaging  20  connected thereto. 
         [0100]    In a next step, the driving mechanism  11  may be activated such as to close the locking means  7   b  which are separating the dispensing chamber B from the discharge outlet  3 , if they are not already in their closed state.  FIG. 7   a  shows such particular (but non-limiting) initial state, in which the packaging  20  is connected to the receiving means  1  and wherein the locking means  7   a  and  7   b  are in their closed position. 
         [0101]    Further, in order to remove any oxygen content from the dispensing chamber B, the atmospheric control means connected to said dispensing chamber B are controlled to provide excess of inert gas such as nitrogen to said second chamber in order to remove any oxygen content therefrom. This is in particular obtained by dedicated flushing of the chamber B as outlined above with respect to the receiving chamber A. In particular, the inert gas is introduced via an injection valve  40   a.  For removing excess of air respectively oxygen from chamber B, a relief valve  40   b  may be (in certain, non-limiting embodiments) arranged within chamber B. It is noted that for the same purpose, receiving chamber A may be additionally equipped with an injection and/or relief valve  40   a,   40   b.    
         [0102]    Thus, a predefined atmospheric environment is obtained also in said dispensing chamber B. Thereby, in certain, non-limiting embodiments, the locking means  7   b  are also designed to prevent any gas and in particular any oxygen gas and/or water vapour to pass from the discharge outlet  3  into the dispensing chamber B. 
         [0103]    As depicted in  FIG. 7   b  , the first locking means  7   a  is now opened such that at least one capsule may be transferred from the receiving chamber A to the dispensing chamber B, supported by the capsule transport means  6  of the device and/or by gravity (see Arrow C in  FIG. 7   b ). In a particular, non-limiting embodiment, the dispensing chamber B is sized to accommodate at least one capsule, as shown in  FIG. 7   b.    
         [0104]    Then, as shown in  FIG. 7   c , the locking means  7   a  are closed again such as to provide an oxygen and/or water vapour barrier between the receiving chamber A and the dispensing chamber B. Thereby, any succeeding capsules which may be automatically fed through the transport means  6  of the device towards the dispensing chamber B are kept within the packaging  20  respectively within the receiving chamber A, as the locking means  7   a  cuts off the transport path between the respective chamber A and B. 
         [0105]    In a further step as shown in  FIG. 7   d , the locking means  7   b  are brought into their open position in order to open a capsule transport path from the dispensing chamber B to the discharge outlet  3  of the device. The capsule is thus made to exit the discharge outlet  3  of the device. The discharge outlet  3  may comprise a slide and/or a support member  3   a  which transports the capsule from the outlet  3  towards a collecting portion  3   b.  A consumer may then collect the dispensed capsule  10  from the collecting portion  3   b.    
         [0106]    Alternatively, the dispensing device may be arranged in combination with a beverage preparation machine such that the dispensed capsule  10  is transferred from the discharge outlet  3  directly into a brewing chamber of the machine. 
         [0107]    In a further step, the locking means  7   b  may be reclosed such as to prevent fluid flow from the discharge outlet  3  to the dispensing chamber B. 
         [0108]    It is noted that the atmospheric control means  15  are, in certain, non-limiting embodiments, adapted for providing inert gas to the respective chamber in response to opening and/or closing of the respective locking means and/or in response to a user request for a dispense process of a dedicated capsule  10 . 
         [0109]    Furthermore, the atmospheric control means  15  may be adapted to continuously monitor and/or adjust the atmospheric environment within at least the receiving chamber A and within the packaging  20  connected thereto by provision of inert gas. 
         [0110]      FIGS. 4 and 5  show a further particular (but non-limiting) embodiment of a dispensing machine according to the presently disclosed and/or claimed inventive concept(s). In certain, non-limiting embodiments, the machine  100  comprises  4  dispensing devices  50 ′- 50 ″″ as previously described with reference to  FIGS. 1 to 3 . Thereby, in certain, non-limiting embodiments, the dispensing devices are equipped with packaging containers  20  each holding different types of capsules such as to provide a variety among which the consumer may choose. 
         [0111]    As shown in  FIGS. 4 and 5 , the inventive device  50  may comprise a dedicated user interface comprising at least a dispense button or activation means  18  suitable for initiating a dispense process of a capsule from the packaging  20  to the discharge outlet  3  of the respective device. 
         [0112]      FIG. 6  relates to a storage means  20  respectively a packaging which comprises a plurality of capsules  10   a - 10   f  enclosed therein. 
         [0113]    In certain, non-limiting embodiments, each of the capsules  10  comprises a first and second respectively an inlet and outlet face  30   a,   30   b  which are sealed together at a circumferential outer rim portion  30   c,  thereby enclosing a predefined portion of beverage ingredients. 
         [0114]    In certain, non-limiting embodiments, the packaging  20  is made of an outer material comprising gas such as oxygen and/or water vapour barrier properties, such as e.g. polyethylene, polypropylene, EVOH, a multilayer-structure comprising oxygen barrier properties or aluminium. 
         [0115]    In certain, non-limiting embodiments, the capsules  10   a , 10 ′, 10   e,   10   f  are arranged within the packaging in a stacked arrangement as indicated in  FIG. 6 . 
         [0116]    In certain, non-limiting embodiments, the packaging  20  comprises a tubular member  20   a  having a closed bottom portion  20   b  and an opening  20   c.    
         [0117]    In certain, non-limiting embodiments, the packaging is hermetically closed by arranging a closing member  22  to cover the opening  20   c.  Within the packaging in the closed state, a predefined atmospheric environment is present. Thereby, in certain, non-limiting embodiments, the packaging is essentially void of any oxygen. In certain, non-limiting embodiments, the packaging  20  in its initial state is filled with inert gas such as e.g. nitrogen. 
         [0118]    In certain, non-limiting embodiments, the closing member  22  is sealed to an outer rim portion of the opening  20   c.  Thereby, usual techniques such as thermo-welding may be applied to establish a connection between the closing member  22  and the rim portion or boundary portion of opening  20   c.    
         [0119]    The closing member  22  comprises oxygen and/or water vapour barrier properties such as to prevent oxygen from being transported into the packaging  20  in the closed state thereof. 
         [0120]    In a particular, non-limiting embodiment, the closing member  22  is made from e.g. aluminium, polyethylene, EVOH or a multilayer-structure comprising such oxygen barrier properties. In certain, non-limiting embodiments, the closing member  22  is an integral part of a first capsule  10   a  stored within the packaging  20 . Thereby, the closing material presents an outer face  30   b  of the capsule. 
         [0121]    In certain, non-limiting embodiments, the first capsule  10   a  is made completely from said material providing oxygen and/or water vapour barrier properties. Alternatively, the closing member  22  is constituted by a first face of the capsule  10   a,  whereby a second face  22   a  is made from oxygen-permeable material. 
         [0122]    In certain, non-limiting embodiments, the connection between the closing member  22  and the packaging  20  is designed to be disengaged or cut during connection of the packaging  20  with dedicated receiving means  1  of the dispensing device  50 . Alternatively or in addition, the receiving means  1  may comprise opening means which enable the disengagement of the first capsule  10   a  from the packaging  20 , whereby the sealed connection between said first capsule  10   a  and the packaging  20  is disengaged. Accordingly, the first capsule  10   a  may directly be transferred from the packaging  20  into the receiving means  1  and thus urged towards a receiving chamber A of the device when the packaging  20  is connected to the receiving means  1 . 
         [0123]    In addition, in certain, non-limiting embodiments, the packaging  20  comprises connection means  21  such as e.g. an outer screw thread  1   b  (see  FIG. 7   a ) or means for interacting with a bayonet-type connection member  1   a  of the device  50  by means of which the packaging  20  may be connected with the receiving means  1  of the device  50 . 
         [0124]    Furthermore, the packaging  20  may as well be equipped with a cap  25  such as to protect the opening  20   c  from unintentional opening during handling, transport and/or storing thereof. The cap  25  may be removably connected to the packaging  20  such as e.g. by means of the connection means  21  arranged at the vicinity of the opening  20   c.    
         [0125]    The cap  25  may be made of gas (oxygen) barrier material and/or water vapour barrier material such as e.g. polyethylene, polypropylene, EVOH, a multilayer-structure comprising oxygen barrier properties or aluminium. 
         [0126]      FIG. 8  depicts particular (but non-limiting) method steps S 1  to S 5  during the discharging process of a capsule  10  from packaging  20 . 
         [0127]    In a first step S 1 , flushing of the chambers A,B with excess inert gas, such as (but not limited to) nitrogen, is carried out by means of injection valve(s)  40   a  and relief valve(s)  40 ( b ) connected to the atmospheric control means  15  (see  FIG. 2 ). In a particular, non-limiting embodiment, only dispensing chamber B is flushed with excess inert gas. During this flushing step S 1 , in certain, non-limiting embodiments, chamber B is void of any capsule and the first and second locking means  7   a,   7   b  are in an initial closed position (see  FIG. 7   a ). 
         [0128]    In a next step S 2 , the locking means  7   a  are opened, which leads to a transport of a single capsule from the multiple-capsule holding packaging  20  to the receiving chamber B (see  FIG. 7   b ) due to gravity. Due to the controlled atmosphere being present within packaging  20  and chamber B, the opening of locking means  7   a  separating chamber B from receiving chamber A and the packaging  20  does not lead to any ingress of oxygen gas or water vapour from the capsule discharge outlet  3  to the receiving means  1  of the device. 
         [0129]    In step S 3 , the locking means  7   a  are closed again in order to enclose capsule  10  within the dispensing chamber B of the device as depicted in  FIG. 7   c.    
         [0130]    In step S 4 , the locking means  7   b  selectively separating chamber B and discharge outlet  3  are opened in order to release capsule  10  from chamber B as depicted in  FIG. 7   d.    
         [0131]    In step S 5 , the locking means  7   b  are closed again in order to separate chamber B from discharge outlet  3 . 
         [0132]    In a possible variant of the method according to the presently disclosed and/or claimed inventive concept(s), upon connection of packaging  20  to the receiving means  1  of device  50 , steps S 1  and S 2  may be replaced by a step S 1 ′ and step S 2 ′. Thereby, during step S 1 ′ opening of the locking means  7   a  takes place (while locking means  7   b  is held in its initial closed position). Accordingly, a first capsule  10  of the packaging  20  will be transferred from the packaging  20  and receiving chamber A to dispensing chamber B. In next step S 2 ′, chamber B, chamber A and packaging  20  connected thereto are flushed with excess inert gas. In certain, non-limiting embodiments, this may be carried out by injection valve  40   a  and relief valve  40   b  connected to chamber B. Accordingly, the controlled atmospheric environment within packaging  20  and chamber A is maintained respectively ensured after connection of the packaging  20  to receiving means  1  of the device. The following steps S 3  to S 5  correspond to the method steps as described above. 
         [0133]    Although the presently disclosed and/or claimed inventive concept(s) has been described with reference to particular non-limiting embodiments thereof, many modifications and alternations may be made by a person having ordinary skill in the art without departing from the scope of this presently disclosed and/or claimed inventive concept(s) which is defined by the appended claims.
