[0242] With reference to the FIGS. 1-12 a first example of a disposable cartridge 1 filled with a single serve portion 2 of a liquid ingredient to be combined with a base liquid for the preparation of a liquid product will be described. FIGS. 13 and 14 illustrate an alternative of the valve member.

[0243] In this description, according to a preferred application of the invention, the liquid ingredient is a beverage concentrate that is to be combined with a flow of carbonated water to fill a single serve container, e.g. a drinking glass, with a single serving of a carbonated beverage.

[0244] In an embodiment the device also, or alternatively, is embodied to combine the liquid ingredient with non-carbonated water, e.g. hot or cold non-carbonated water. Generally carbonated water will be cold water.

[0245] Whilst use in the field of preparation of carbonated beverages is envisaged it will be clear that the inventive cartridge and/or apparatus can also be employed for the preparation of other liquid products, e.g. in the pharmaceutical field, etc.

[0246] The disposable cartridge 1 has an injection molded monolithic plastic body 2 with a bottom 3 having an underside 3a and with a circumferential wall 4, an upper edge 5 embodied as an outwardly protruding flange, of the circumferential wall bounding a filling aperture through which the cartridge can be filled with a liquid ingredient.

[0247] The filling aperture of the cartridge is hermetically sealed by a top sealing film 6, of which the circumference is fixed on the upper edge 5.

[0248] The bottom may e.g. have a diameter between 25 and 75 millimeters, e.g. between 40 and 60 millimeters. The circumferential wall adjoining the perimeter of the bottom may e.g. have a height between 25 and 75 millimeters, e.g. between 40 and 60 millimeters.

[0249] The bottom is provided with a molded aperture 8, e.g. formed by a downward protruding collar portion 9 of the bottom.

[0250] The plastic body further comprising a column 11 that is integrally molded with a portion of the bottom, here a central portion. The column 11 projects upwards from the bottom to an upper end of the column. Through the column a bore 12 extends from the upper end of the column 11 and ending in the aperture 8 in the bottom.

[0251] The plastic body bounds a reservoir that is at least partially filled with said liquid ingredient between said column 11 and the circumferential wall 4.

[0252] A tubular valve member 20 is slidably arranged in the bore 12 in the column 11, through which valve member a channel 21 extends from an inlet 22 at a top end of the valve member to an outlet 23 at a bottom end of the valve member 20. In this example, as preferred, the valve member 20 is vertically movable within the bore 12.

[0253] The column is provided with one or more first dispensing passages 15 between an exterior of the central column 11 and the bore 12.

[0254] The tubular valve member 20 is provided with one or more second dispensing passages 25, here extending between the exterior side of the valve member 20 and the channel 21 within the valve member 20.

[0255] In a raised sealing position of the valve member relative to the column 11, see FIG. 1, the one or more second dispensing passages 25 in the valve member 20 are out of register with the one or more first dispensing passages 15 in the column 11, such that the reservoir is closed.

[0256] In a lower dispensing position of the valve member 20 relative to the column 11, the one or more second dispensing passages 25 in the valve member 20 register with the one or more first dispensing passages 15 in the column 11, such that the reservoir is opened.

[0257] The top sealing film is pierceable, so that a base liquid feed lance 120 can be pierced through the top sealing film and connected to the inlet 22 of the channel 21 in the valve member, so that the base liquid can be fed into the channel. This liquid exits the channel 21 and thereby the cartridge from the outlet of the valve member.

[0258] The valve member 20 is movable downwards by a force exerted thereon by said base liquid feed lance 120 in order to move from the sealed position to the lower dispensing position, thereby opening the reservoir and allowing dispensing of liquid ingredient from the reservoir via said first and second dispensing channels 15, 25.

[0259] In this embodiment it is envisaged that the one or more second dispensing passages 25 are arranged such that the dispensed liquid ingredient is combined with the base liquid within the channel 21 prior to exiting said channel, noting that further blending may occur as the combined liquid travels to the drinking receptacle or even in the drinking receptacle, e.g.

[0260] glass.

[0261] It will be appreciated that in the design shown in FIGS. 1-12 the valve member has an exterior side and an interior side that delimits the channel 21, wherein the one or more second dispensing passages 25 are embodied to extend between said exterior side and interior side of the valve member.

[0262] It will be appreciated that in the design shown in FIGS. 1-12 the outlet of the valve member 20 forms the actual dispensing outlet for the combined base liquid and liquid ingredient.

[0263] In view of further appreciation of the cartridge depicted in FIGS. 1 and 2 and its cooperation with an appropriate dispensing apparatus, e.g. beverage preparation and dispensing apparatus, now the preparation of a beverage or other liquid product will be discussed with reference to FIGS. 3-12. It is noted that other cartridges discussed herein can be used in conjunction with the same apparatus and dispensing can be achieved on the basis of the same principles.

[0264] FIGS. 3-12 depict components of an apparatus 100 including [0265] a housing 105, [0266] a holder 110 that here is movable relative to the housing 105, here a sliding drawer, for accommodating and retaining the cartridge 1 at a dispensing location in the apparatus, [0267] a base liquid feed assembly with a base liquid feed lance 120 that is disposed at the dispensing location, which lance 120 is embodied to pierce through the top sealing film 6 of the cartridge 1 and to connect to the channel 21 of the valve member 20 of the cartridge 1, so that base liquid can be fed into the channel 21.

[0268] The apparatus 100 is provided with a pressurized gas source, preferably a pressurized air source, e.g. an air pump or gas bottle, here schematically depicted at 130.

[0269] The apparatus 100 is adapted to bring the pressurized gas source 130 in direct communication with the reservoir of the disposable cartridge 1 so as to allow the liquid ingredient therein to be pressurized by said gas thereby assisting the dispensing of the liquid from the reservoir when the valve member 20 of the cartridge 1 has been brought into the dispensing position thereof. This is advantageous if the liquid ingredient is rather viscous and also allows for control of said dispensing, e.g. in view of the ratio between the liquid ingredient and the base liquid, e.g. during a dispensing cycle of a single beverage. The gas pressure control may also be used to compensate, if needed, for any temperature dependent viscosity effect of the liquid ingredient, e.g. increasing gas pressure when the liquid ingredient is cold. In an embodiment the apparatus may comprises a temperature sensor adapted to sense the temperature of the liquid ingredient and/or of the cartridge at the start of the dispensing cycle, e.g. when placed in the holder of the apparatus or when arriving at or moving to the dispensing location. One can also envisage a user inputting said temperature, e.g. “cartridge taken from refrigerator” and “ambient temperature cartridge”. One can also envisage the top sealing film have a temperature responsive coloring area, that changes color due to temperature change and thereby provides an indication of the actual temperature of the liquid ingredient. The apparatus may then have a sensor reading the temperature or an indicator thereof on the cartridge, or the user may be guided to provide the correct input for the apparatus.

[0270] The apparatus 100 comprises a pressurization dome member 140 having along a periphery thereof an outer gas seal 145 that is adapted to sealingly engage the disposable cartridge 1 around a location where the top sealing film is pierced to allow entry of pressurized gas into the reservoir. Here the outer gas seal 145 is embodied to seal onto an upper end 5 of a circumferential wall of the disposable cartridge 1.

[0271] The pressurized gas source 130 is connected to the dome member 140 so as to allow feeding of pressurized gas beneath the dome member 140 within the space sealed by the outer gas seal thereof that sealingly engages the disposable cartridge. As the top sealing film has been pierced, e.g. in a manner to be discussed below, this supply of pressurized gas, e.g. air, pressurized the liquid ingredient.

[0272] The base liquid feed lance 120 here protrudes from the dome member 140. The lance and the dome member 140 are integrated so as to move in unison.

[0273] The lance 120 is provided with a gas seal 146, here an 0-ring, that seals onto the top end of the column to avoid entry of pressurized air into the channel.

[0274] The dispensing apparatus has an operable displacement device 150, here with an excenter mechanism 151 and an electric motor 151, which is adapted to produce a movement of the dome member 140 and lance 120 relative to the cartridge 1 that is held in the holder 110.

[0275] When the displacement device 150 is operated the lance 120 pierces the top sealing film 6 and connects to the channel 21 of the valve member 20. Continued downward motion of the lance 120, here along with the dome member 140, causes the base liquid feed lance to move the valve member 20 to the dispensing position thereof, thus pressing the valve member downwards from the raised sealing position to the lower dispensing position thereof and thereby allowing the dispensing of beverage concentrate or the like from the cartridge 1.

[0276] As discussed the liquid feed assembly is equipped for feeding in water as the base liquid, e.g. carbonated water, e.g. selectively carbonated and non-carbonated water, here via hose 121. For example the liquid feed assembly comprise a pump for the base liquid and/or the liquid feed assembly is connected to a water mains, e.g. via an intermediate heat exchanger for cooling and/or heating said liquid, and/or via an intermediate carbonator for causing carbonization of the water.

[0277] The holder 110 for the cartridge 1 is equipped to accommodate and retain the cartridge in a substantially horizontal position with the bottom downwards. The holder has an aperture below the bottom of the cartridge 1 in such a way that during dispensing of the liquid product said product remains clear of the holder. This avoids undue disturbance of the low, e.g. avoiding reduction of the carbon dioxide content of the liquid product and/or soiling of the apparatus and/or cross contamination between successive servings.

[0278] At a distance below the dispensing location of the holder the apparatus has a standing place for a mug or other receptacle, e.g. a drinking glass.

[0279] The user starts here by sliding open the drawer 110 and placing the cartridge in a corresponding cavity in the drawer 110. As is preferred the cartridge is now suspended from its upper flange as the holder forms a corresponding support surface for said upper flange. Now the user closes the drawer 110 by sliding it with the cartridge 1 into the housing so that the cartridge is moved to the dispensing location of the apparatus 100. This situation is depicted in FIGS. 6, 7.

[0280] The displacement device 150 is now operated so that the lance 120 pierces the top sealing film 6 and connects to the channel 21 of the valve member 20. Continued downward motion of the lance 120, here along with the dome member 140, causes the base liquid feed lance to move the valve member 20 to the dispensing position thereof, thus pressing the valve member downwards from the raised sealing position to the lower dispensing position thereof and thereby allowing the dispensing of beverage concentrate or the like from the cartridge 1.

[0281] As is preferred, the cartridge is provided with one or more piercing members 28 , here two, that are arranged underneath the top sealing film 6, so that pressing the top sealing film downwards, here by the base liquid feed lance 120, causes said one or more piercing members 28 to engage the top sealing film and the locally rupture the top sealing film thereby providing one or more holes that allow for introduction of pressurized gas into the reservoir in order to pressurize the liquid ingredient therein so as to assist dispensing thereof via the dispensing passages when the valve member 20 is in the dispensing position thereof. In this example the one or more piercing members are embodied as one or more integrally molded spike formations.

[0282] This situation is depicted in FIGS. 8 and 9.

[0283] Now the supply of carbonated water as well as of pressurized gas, e.g. air, is started, possibly with some timed delay of the one relative to the other. The liquid ingredient is now assisted in its travel through the first and second dispensing passages and in this embodiment blends with the water travelling through the channel 21 prior to the blended liquid exiting the channel via the outlet thereof. This process is depicted in FIG. 10.

[0284] Once the single serving is prepared the flow of water or other base liquid is stopped. If desired some gas flow main be continued to fully empty the cartridge and/or to assure that the final drops of liquid ingredient, e.g. beverage concentrate, are discharged. This avoids loss of ingredient and soiling of the apparatus. This is depicted in FIG. 11.

[0285] FIG. 12 depicts the end of the dispensing cycle, wherein the dome member 140 and lance 120 have been moved to their initial position, clear from the cartridge 1, allowing the removal of the cartridge 1, here by opening the drawer 110 and taking out the cartridge.

[0286] In FIGS. 13 and 14 an alternative embodiment of the cartridge 1 has been shown, in particular as concerns the embodiment of the second dispensing passages 125 of the valve member 20′.

[0287] The valve member 20′ has an exterior side and an interior side that delimits the channel 21. The one or more second dispensing passages 125 are embodied as one or more dispensing grooves in the exterior side of the valve member. These one or more dispensing grooves 125 have a groove outlet 126 from which the liquid ingredient is dispensed. In practice, even whilst the outlet is not adjoining the channel or outlet thereof, the liquid ingredient flows directly to join the outflow of (carbonated) base liquid so as to blend therewith. It has been found that this joining of one or more subflows of liquid ingredient, e.g. beverage concentrate, on the exterior of the valve member (or other dispensing duct member of a disposable cartridge) with a water flow, e.g. of carbonated water, through the interior of the valve member or duct member avoids undue loss of carbonization of the water whilst providing an acceptable blending.

[0288] In a preferred embodiment between three and six groove outlets are disposed around a lower end portion of the valve member 20′.

[0289] The discharge grooves 125 on the exterior side of the valve member here each have a collector groove portion 127, which in the dispensing position of the valve member, acts as receptacle for liquid ingredient, e.g. said liquid ingredient being jetted from an associated first dispensing passage 15 under the influence of the pressurization of said liquid ingredient by pressurized gas. A further portion128 of said groove 125 adjoins said collecting portion 127 so as to allow said liquid ingredient to overflow, e.g. like a siphon, said collector portion and then flow downwards towards an outlet of said groove. This tortuous path avoids the high speed collision of liquid ingredient jet with carbonated water, as the bends in the path and/or the collector groove portion reduce the speed of the liquid ingredient. It will be appreciated that the grooves 125 may have other tortuous designs.

[0290] As can be seen in the FIGS. 1-12 the channel 21 in the valve member 20 has an upper portion with a first diameter and an adjoining lower portion extending up to the outlet. This lower portion and the outlet have a second diameter. The first diameter is greater than the first diameter. It is shown that the base liquid feed lance 120 has an insertion portion adapted to be inserted into the wider upper portion of the channel 21. The feed lance 120 has an internal feed channel therein having a feed channel diameter substantially equal to this second diameter, e.g. between 0.9 and 1.1 times the second diameter, thereby avoiding undue constriction and/or expansion of the flow of base liquid when passing from the feed lance into the second portion of the channel. This is also beneficial in view of loss of carbonization when carbonated water travels through the lance and the connected valve member.

[0291] It is shown here that the bore 12 has an upper portion with a first diameter and an adjoining lower portion with a second diameter smaller than said first diameter, and the exterior of the valve member 20 has an upper portion with a diameter so as slidably fit in said upper portion of the bore and a lower portion so as to slidably fit in said lower portion of the bore. It is shown that the bore has a shoulder, e.g. between said upper and lower portion of the bore, and the valve member has on the exterior side thereof an abutment surface adapted to rest against said shoulder in the dispensing position of the valve member.

[0292] It is shown that the valve member and the bore—at least in the sealed position of the valve member—form one or more seals between them, e.g. in an embodiment according to FIGS. 1, 2 a seal between them that shields the one or more dispensing passages from the atmosphere.

[0293] It is illustrated that the cartridge body is a rigid body with the bottom maintaining its shape when the valve member 20 is moved between its sealing position and dispensing position, e.g. moved vertically downward between said positions.

[0294] It is illustrated that the cartridge body comprises a column 11, e.g. a column that is integrally molded with a portion of the bottom, e.g. a central portion of the bottom, which column 11 projects upwards from the bottom to an upper end of the central column, through which column the bore 12 extends from the upper end of the column and ends in said aperture in the bottom.

[0295] It is illustrated that the cartridge body is an injection molded monolithic plastic body.

[0296] In an embodiment the cartridge may have a bottom sealing film, which is placed along the underside of the bottom to hermetically seal the aperture and/or the outlet of the valve member. In such embodiment, preferably, the valve member is movable vertically downward from said sealed position to said dispensing position, wherein the bottom sealing film is pierceable and is placed so as to be engaged and pierced by the valve member when the valve member is moved down to the dispensing position thereof, said piercing of the bottom sealing film causing opening of said outlet of the channel of the valve member and/or of the aperture.

[0297] It is shown that the top end of the valve member rests against, here is sealed to, the top sealing film 6 when the valve member 20 is in the sealing position.

[0298] It is shown that the cartridge body forms a supporting surface of the cartridge, which supporting surface lies at a distance below the bottom, e.g. below—when present—a bottom sealing film, so that the bottom or bottom sealing film lies higher than any bearing surface when the cartridge is placed on it.

[0299] It is shown that the cartridge body has a circumferential wall having an upper rim bounding an opening, wherein a top sealing film is fixed to said upper rim, e.g. embodied as an outwardly projecting flange 5, e.g. said radially projecting flange being embodied to support the cartridge on a bearing surface of a dispensing device. As is preferred the outer gas seal engages also on said upper rim or on the top sealing film on or adjacent the upper rim.

[0300] It is shown that the valve member is provided with one or more snap portions 29 adapted to form a snap fit as the valve member is moved into the dispensing position thereof.

[0301] It is shown that the outlet of the channel has a diameter between 6 and 10 millimeter, e.g. about 8 millimeter.

[0302] It is shown that the cartridge body has a circumferential wall around the perimeter of the bottom and wherein the bore is concentric relative to an axis of the circumferential wall of the cartridge.

[0303] With reference to FIGS. 15-24 now another example of a disposable cartridge will be discussed, which cartridge 50 is filled or can be filled (when the top seal is not yet applied) with a single serve portion of a liquid ingredient to be combined with a base liquid for the preparation of a liquid product, e.g. a liquid food product suitable for human consumption, e.g. a beverage concentrate to be combined with water, e.g. carbonated water, for the preparation of a beverage.

[0304] The disposable cartridge 50 is filled with a single serve portion of a liquid ingredient 51, preferably to a level so that a head space 52 is present above the liquid ingredient.

[0305] The liquid ingredient 51 is in this example a beverage concentrate to be combined with water, here carbonated water, for the preparation of a beverage for human consumption.

[0306] The cartridge has a molded plastic cartridge body 52 with a bottom 53 and a circumferential wall 54 that extends upward from the periphery of the bottom 53 to a top of the body 52.

[0307] Here, as preferred, the top edge of the circumferential wall 54 is provided with an outwardly protruding circumferential flange 55, that extend around a filling aperture for filling the liquid ingredient into the cartridge.

[0308] The body 52 delimits a reservoir that is filled with the single serve portion of liquid ingredient 51.

[0309] As can be seen the filling aperture is in communication with this reservoir.

[0310] The aperture is hermetically sealed by a top sealing film 56 that is secured to the circumferential wall 54, here, as preferred, to the flange 55 thereof. For example the top sealing film is heat-sealed to said flange 55 after the reservoir has been filled.

[0311] The cartridge body 52 further comprises a column 60 having a portion that projects upwards from the bottom 53 to an upper side of the column 60.

[0312] Here, as preferred, the column 60 is a central column that is centrally arranged within the cartridge 50. Here the circumferential wall is circular in cross-section, as preferred, and the column 60 is arranged on the vertical axis of the circumferential wall.

[0313] As is preferred the column 60 is integrally molded with the bottom, here a central portion of the bottom, so that the entire body can be manufactured in an injection mold and no later assembly of the column 60 is needed.

[0314] A vertical channel 61 extends through the column 60 from an inlet 62 at a top end thereof to an aperture or outlet 63 in the bottom 53 of the cartridge body 52.

[0315] The bottom 52 has a flexible portion 57 adjacent, here around the column 60, such that the column 60 is movable downwards by a force exerted thereon relative to the top of the body, here relative to the upper edge of the circumferential wall of the body, between a higher initial position (FIG. 15) and a lower dispensing position (FIG. 20).

[0316] As preferred the top end of the column 60 rests against the top sealing film 56 when the column is in the higher initial position. Even more preferred the top end is connected to the top sealing film, e.g. heat-sealed, so as to achieve a sealed connection separating the channel inlet from the reservoir.

[0317] A valve member 70 is arranged within the cartridge 50 and outside of the column 60. As will be apparent from the figures and this description the valve member 70 is stationary arranged within the cartridge 50 so as to be movable, e.g. slidable, relative to the column 60 when the column is moved from its higher initial position (FIG. 15) to its lower dispensing position (FIG. 20).

[0318] The cartridge body 51 is provided with one or more dispensing passages 80 that are arranged to dispense the liquid ingredient 51 from the reservoir.

[0319] In the higher initial position of the column 60, the valve member 70 closes the one or more dispensing passages 80, such that the reservoir is closed.

[0320] In the lower dispensing position of the column 60, made possible by the flexing portion of the bottom, the valve member has remained in place and thereby has effectively moved away from the inlets of the one or more dispensing passages 80, such that the reservoir is opened and liquid ingredient can be dispensed via the one or more passages 80.

[0321] The cartridge 50 can be placed in the apparatus described herein before, wherein the base liquid feed lance 120 is connectable to the inlet 62 of the channel 61 in the column 60, so that the base liquid, e.g. carbonated water, can be fed into the channel 61 and exit the cartridge 50 via the aperture 63 in the bottom of the cartridge.

[0322] In an embodiment, as here, the column 60 has a lower portion that extends below the flexible portion of the bottom, so that the aperture 63 is vertically spaced from said flexible portion.

[0323] In general the one or more dispensing passages 80 are arranged such that the dispensed liquid ingredient is combined with the base liquid within the channel or, in this example, at or near the aperture or outlet 63 of the channel.

[0324] It is illustrated that the bottom, or the lower portion of the column 60, provides a series of outlet openings of the one or more dispensing passages 80 that are arranged in a circular arrangement around the outlet or aperture from which the base liquid, e.g. carbonated water emerges. In a preferred embodiment the one or more outlet openings 81 are arranged to dispense the liquid ingredient basically as an annular shroud around the jet of base liquid.

[0325] The jetted base liquid and liquid ingredient adjoin one another rather immediately after they emerge from the cartridge and in the further duration of travel they intermix, possibly with a final mixing occurring as the mixture swirls into the glass or other beverage drinking container. It is noted that said mixing is in particular seen when carbonated water is used as base liquid and then this manner of combining the liquid ingredient with the carbonated water is greatly beneficial for keeping the carbondioxide in the base liquid. In contrast, an effective jetting of one or more streams of liquid ingredient into the stream of carbonated water is observed to agitate the carbonated water in undue manner and thereby cause much of the carbondioxide to escape so that the final beverage contains limited carbondioxide.

[0326] It is illustrated that the dispensing passages 80 have multiple, here four, outlet openings 81 in the end face of the lower portion of the column.

[0327] The dispensing passages 80, here four, also have one or more inlets 82 that are initially closed by the valve member 70. It is illustrated that each passage 80, here four, has a single inlet 82 but other arrangements, e.g. with multiple inlets for a single passage or multiple passages linking to a common inlet, are also possible.

[0328] It is illustrated that an inlet 82 is oriented at an angle relative to the passage 80 such that a jet of liquid ingredient emerging from an opened inlet, e.g. due to pressurization of the liquid ingredient as discussed herein, collides against a wall portion of the passage thereby reducing, preferably annihilating, the speed of said jet.

[0329] In a most desired manner, even with a jetting of liquid ingredient from the inlet 82, the liquid ingredient effectively streams down mainly under the influence of gravity with the stickiness of the liquid ingredient in combination with an appropriate narrow shape of the passage maintain a slow speed of the emerging liquid ingredient.

[0330] Effectively it is desirable for the passage 80 to act as a flow resistor for the liquid ingredient, so that pressurization of the liquid ingredient as discussed herein using pressurized gas, can be used to cause an even stream of liquid ingredient from the one or more dispensing passage outlets 81.

[0331] In an embodiment the width, here the radial distance between opposing vertical wall portions, of the dispensing passages is about 0.8 mm. Here the outlet or dispensing aperture 63 has a diameter of about 10 mm. For example the dispensing passage outlet or outlets 81 are within 0.4 to 1.0 mm from the dispensing aperture 63 so that the shroud flow of liquid ingredient will easily adjoin the flow of base liquid, in particular when carbonated water is employed.

[0332] The valve member 70 can be manufactured as a separate component that is assembled into the cartridge. It is however more preferred to embody the valve member 70 by means of co-injection molding of the valve member after the body 52 has been molded. As will be appreciated the valve member 70 should not become unitary with the body 51 in such a manner that it would be solidly fused to the column and the flexible portion of the body so as to obstruct the illustrated way of operation of the valve member and cartridge.

[0333] It is proposed to co-inject the valve member 70 such that only a light adherence, or even no adherence at all, is created between the plastic of the valve member and the plastic of the body 52 including the column 60. This can be realized by selecting non-compatible plastics, e.g. the body can be made of amorphous plastic, for example of PP. The valve member can be molded from crystalline plastic, e.g. polycarbonate PC or ABS. These combinations allow to obtain a light adherence of the valve member 70 to the surfaces of the body 52 that are in contact with the valve member.

[0334] It is illustrated that the valve member has an annular portion 71 surrounding the column 60, which annular portion 71 has a sealing face that extends over the inlets 81 of the passages 80 and is in sealing contact with a corresponding annular sealing face around the lower end of the column 60.

[0335] In order to maintain the stationary position of the valve member 70 when the column 60 is pressed down, the valve member 70 here has one or more spoke portions 72 that extend away from the annular portion 71 to be supported on a non-flexing portion 58 of the bottom and here, as is preferred also extending to support against the circumferential wall 54 of the body.

[0336] It is illustrated that the non-flexing bottom portion 58 extends around the flexing portion 57 of the bottom.

[0337] For example three or four spokes extend away from the annular portion 71.

[0338] As can be seen in FIG. 30, the valve member 70 does not follow a downward motion of the column, with the result that the valve member no longer covers or closes the one or more inlets 82 of the one or more passages 80. Even when, as here, the valve member 70 was molded to extend over the flexing bottom portion 57, the non-adherence or light adherence allows the flexing portion to deform and move away from the valve member.

[0339] As is illustrated it is envisaged that the flexing bottom portion, in the downward dispensing portion of the column, forms a downward funnel 59 so that residual liquid can reach the inlets 82 that are, optimally, arranged near the lower end of the column 60 and thus at the bottom of the funnel 59. If, as desired, the flexing bottom portion 57 flexes back to or substantially into its initial position the same arrangement avoids or further hinders any residual leakage of liquid ingredient from the cartridge after a beverage or the like has been prepared and the feed lance 120 has been moved upwards, even in case the valve member 70 does not seal again the inlets 82.

[0340] FIG. 20 also illustrates the piercing or otherwise rupturing of the top sealing film 56 in order to allow entry of pressurized gas into the reservoir for the purpose of pressurization of the liquid ingredient within the reservoir. This may be done by one or more spike members or the like formed integrally with the body of the cartridge underneath the film 56. Here such a piercing is shown at 56a. The piercing by the lance 120 of the portion of the film covering the inlet of the channel 61 is shown at 56b.

[0341] FIG. 20 very schematically illustrates how the, rather slow moving, streams of liquid ingredient adjoin the outside of the central jet of base liquid, here carbonated water, and in the further course of travel into the drinking vessel gradually intermix with the base liquid. In case of carbonated water it is preferred that the emerging streams of liquid ingredient do not intersect the water flow but rather flow along and then adjoin, preferably as an annular shroud, the water flow.

[0342] As discussed with reference to the cartridge of FIG. 1 the channel in the column has an upper portion 61a with a first diameter and an adjoining lower portion 61b extending up to said aperture or outlet 63, said lower portion and outlet having a second diameter, wherein the first diameter is greater than said first diameter.

[0343] The base liquid feed lance 120 has an insertion portion adapted to be inserted into said upper portion 61a of the channel, wherein said feed lance has an internal feed channel therein having a feed channel diameter substantially equal to said second diameter, e.g. between 0.9 and 1.1 times the second diameter, thereby avoiding undue constriction and/or expansion of the flow of base liquid when passing from the feed lance into the second portion of the channel.

[0344] With reference to FIGS. 25-28 now another example of a disposable cartridge according to the invention will be discussed.

[0345] The cartridge 70 is filled with a single serve portion of a liquid ingredient 71, e.g. a beverage concentrate, to be combined with a base liquid, e.g. carbonated water, for the preparation of a liquid product, e.g. a beverage.

[0346] As can be seen the cartridge 70 has, or may have, many features already discussed with reference to the other examples. These features will not be discussed again as the skilled person will appreciate the corresponding features and functionality thereof.

[0347] The molded plastic cartridge body 72 has a bottom with a flexing portion 73 surrounding the lower end of the column 75 and, as preferred, a non-flexing portion 74 surrounding the flexing portion 73. As is preferred the column 75 has a lower portion that protrudes below the flexing bottom portion 74 of the bottom more preferably with the flexing portion in initial position forming a raised bulb into the cartridge.

[0348] The body 72 further has a circumferential wall 76 and delimits a reservoir that is filled with a single serve portion of a liquid ingredient.

[0349] The top has an aperture in communication with the reservoir, primarily used for filling the reservoir with liquid ingredient.

[0350] The filling aperture is hermetically sealed by a top sealing film 77.

[0351] As discussed already the column 75 has a portion that projects upwards from the bottom to an upper side of the column, which, as preferred, is sealed to the top sealing film. Possibly the top sealing film has a hole there, so that it is not necessary for the lance 120 to pierce the top sealing film. The same hole could also be present in other examples discussed herein, e.g. with the addition that the top sealing film is properly sealed to the top end of the column or tubular valve member.

[0352] Channel 75a extends through the column 75 from an inlet at a top end thereof to an aperture at the bottom side of the cartridge body, that is here delimited by the lower protruding portion of the column.

[0353] The column 75 is movable downwards by a force exerted thereon relative to the top of the body, e.g. relative to the upper edge of a circumferential wall of the body, between a higher initial position (FIGS. 25,26) and a lower dispensing position (FIGS. 27, 28).

[0354] The base liquid feed lance 120 is connectable to the inlet of the channel in the column, so that the base liquid can be fed into the channel 75a and exit the cartridge via the aperture in the bottom of the cartridge.

[0355] The cartridge body is provided with one or more dispensing passages 80 arranged to dispense the liquid ingredient from the reservoir, which one or more dispensing passages have one or more dispensing passage outlets 81 arranged so that liquid ingredient emerging therefrom adjoins a base liquid stream emerging from the aperture at the bottom side of the channel 75a.

[0356] The cartridge 70 has a bottom sealing film 92, which is placed along the side of the bottom and hermetically seals at least one or more outlets 81 of the one or more dispensing passages 80. This bottom sealing film 92 is secured to the cartridge at one or more locations remote from the one or more outlets, here to the non-flexing part 74 of the bottom.

[0357] The bottom sealing film 92 is adapted to rupture and/or to tear away from the one or more outlets due to the column being moved downwards to its lower dispensing position, thereby opening the dispensing channel outlets 81.

[0358] As is illustrated it is preferred for the bottom sealing film to have a hole 93 therein aligned with the aperture of the channel 75a from which the base liquid emerges, so that the film 92 will not cause an undue disturbance of the outflow of said base liquid.

[0359] It will be appreciated that the design discussed with reference to FIGS. 25-28 does not require the presence of a valve member 70 as the film 92 keeps the outlets 81 closed until the column 75 is moved downwards. Yet, in an embodiment, such a valve member 70 may still be provided, in which case the film 92 mainly will serve to counter an ingress of matter into the dispensing passages. The latter can of course also be counter by packaging the cartridge in an outer envelope, e.g. a sealed sachet containing one or more cartridges which can also be done for any other cartridge discussed herein.

[0360] Reference numeral 77a again indicates the possibility to establish a gas pressure within the reservoir in order to assist the dispensing of liquid ingredient from the cartridge, e.g. as discussed in detail herein.

[0361] FIG. 29 schematically shows a beverage dispensing apparatus 200 with the cartridge 50 of FIG. 25 in opened condition.

[0362] The apparatus has a housing 205 and a holder 210 for the cartridge, here a drawer, for accommodating and retaining the cartridge 50 at a dispensing location in the apparatus. The dispensing location is directly above the support 215 for a drinking glass 216.

[0363] The apparatus 200 comprises an air pump 230 and a pressurization dome member 240 having along a periphery thereof an outer gas seal that is adapted to sealingly engage the disposable cartridge 50 around a location where the top sealing film is pierced to allow entry of pressurized air from the air pump into the reservoir.

[0364] A base liquid feed lance 220 is integrated with the dome member 240 as a reciprocating unit, here vertically, driven by operable displacement device 250, here with an excenter mechanism and an electric motor, which is adapted to produce a movement of the dome member 240 and lance 220 relative to the cartridge 50 that is held in the holder 210.

[0365] When the displacement device 250 is operated the lance 220 connects to the channel in the column of the cartridge 50. Also—upon further motion of the lance 220—the column is pressed downward to its dispensing position and in the process the protruding foot portion of the column is made to protrude into and through the premade hole in the bottom sealing film.

[0366] The apparatus 200 has a water inlet 260 to be connected to a water mains. If desired the apparatus may comprise a water filter to filter the water flowing into the apparatus.

[0367] Reference numeral 265 denotes a water chiller device to chill the water, e.g. to a temperature between 2 and 10 Celsius.

[0368] The outlet of the water chiller device 265 is connected, via valve assembly 266, on the one hand directly to the lance 220 and on the other hand to a carbonator 270, e.g. an inline or tankless carbonator. A CO2 bottle 275 is also connected to the carbonator 270 so that the CO2 can be dissolved in the chilled water and then fed to the lance 220.

[0369] Reference numeral 280 denotes a flow through water heater adapted to provide hot water to the lance 220. The flow thereof is controlled by hot water valve 281.

[0370] Reference numeral 300 denotes a temperature sensor that is adapted to sense the temperature of the cartridge 50, e.g. when located at the dispensing location in the apparatus.

[0371] The sensor 330 is connected to a gas pressure control device 310 which controls the operation of the air pump 230, e.g. so as to allow for a temperature dependent control of the air pressure to which the liquid ingredient in the reservoir of the cartridge is subjected.

[0372] In embodiments the air pump 230 is adapted to create an air pressure of between 0.5 and 2.5 bars above the atmospheric pressure. In embodiments the air pump 230 will create a predetermined air pressure dependent on a readable indication on the cartridge, e.g. by reading a barcode, preferably said pressure being constant over a dispensing cycle.

[0373] In embodiments a dispensing cycle for a glass of beverage, e.g. of about 250 ml, will take between 15 and 30 seconds.

[0374] In embodiment the volume ratio between the liquid ingredient and the base liquid may be between 1:4 and 1:10. For example a 50 ml volume of liquid ingredient in the reservoir is combined with 200-250 ml of carbonated water to fill a drinking glass.

[0375] In an embodiment the dispensing flow rate of the liquid ingredient from the reservoir is substantially uniform over the dispensing cycle of the base liquid, e.g. about 2-3 ml per second.

[0376] In an embodiment the dispensing apparatus is embodied to receive two cartridges at two side by side dispensing locations, e.g. in a two cavity holder, e.g. a drawer with two cavities. Preferably, for each dispensing locations there is an independently controllable operable displacement device as well as independent control of gas pressurization and of the supply of base liquid, so that effectively two apparatuses are combined in a single housing.

[0377] In an embodiment the apparatus is able to create a beverage on the basis of two cartridges loaded simultaneous into the apparatus, e.g. one cartridge containing a coffee liquid ingredient and the other cartridge containing a milk ingredient, e.g. to make a cappuccino.

[0378] The present invention further relates to cartridges, systems, dispensing apparatuses, and/or method according to the clauses below: [0379] 1. A disposable cartridge filled with a single serve portion of a liquid ingredient to be combined with a base liquid for the preparation of a liquid product, e.g. a liquid food product suitable for human consumption, e.g. a beverage concentrate to be combined with water, e.g. carbonated water, for the preparation of a beverage, the disposable cartridge comprising:
