Description

Apparatus for preparing aerated beverages

Technical Field

The present invention relates to an apparatus for preparing carbonated beverages, and in particular, but not exclusively, to an apparatus for preparing carbonated beverages, and a corresponding method.

Background

Home carbonators are well known in the art and are based on the supply of an aerator station comprising: a removable aerator bottle defining a chamber for receiving a liquid to be carbonated; an inflator bottle interface operable to engage a removable inflator bottle and seal a chamber thereof; a gas inlet line operable to contain pressurized CO ₂ The gas cylinder of gas is fluidly connected to the inflator bottle interface, the gas inlet line generally terminating in a gas inlet nozzle supported by the inflator bottle interface and configured to extend into the chamber of the inflator bottle when the inflator bottle engages the inflator bottle interface; and a gas supply mechanism (including a manually actuated mechanical valve or an electronically controlled solenoid valve) for controllingPressurized CO from a gas cylinder via a gas inlet line to an inflator cylinder ₂ And (3) gas supply. .

In use, liquid (typically water) is added to the chamber of the removable inflator bottle and the removable inflator bottle is connected in a sealed manner to the inflator bottle port. Once the removable inflator bottle is sealed in place, the gas supply mechanism is activated (manually or electrically, depending on the type of device) to supply CO ₂ From the gas cylinder into the liquid in the chamber of the sealed removable inflator bottle, thereby carbonating the liquid. Depending on the desired carbonation level, the gas supply mechanism may be activated one or more times to supply the desired amount of CO ₂ Transferred to a liquid. Once carbonated to the desired level, the removable aerator bottle may be removed from the device by the user and the carbonated liquid may be enjoyed. If the carbonated liquid is intended to be flavored, flavoring (typically in the form of flavoring syrup) may be added to the carbonated liquid in the removable aerator bottle after the removable aerator bottle has been removed from the device.

The present inventors have determined that there is a need for an improved inflator device that provides greater flexibility than prior art home carbonator devices while providing enhanced functionality with minimal additional complexity.

In one embodiment, the first and second cross-sectional shapes are configured such that when the n displaceable tabs are urged into the open position as the rearward hole engaging portion of the penetrating element fully engages the hole formed by the forward hole forming portion, a plurality of n flow gaps (one at each vertex of the n-sided polygonal shape) are formed around the rearward hole engaging portion.

In one embodiment, the capsule further comprises an outlet nozzle (e.g., a substantially cylindrical outlet nozzle) disposed downstream of the frangible seal (e.g., on the underside of the bottom of the container where the frangible seal is disposed on the bottom of the container) and operable to receive fluid from the at least one aperture.

Detailed Description

Fig. 1 and 2 illustrate a portable home inflator apparatus 10 for preparing an inflatable beverage, comprising a housing 12 and an inflator station 20, the inflator station 20 comprising: a removable 450ml aerator bottle 30 defining a chamber 32 for receiving a liquid (typically water) to be aerated; an inflator bottle interface 40 operable to engage the removable inflator bottle 30 and seal the chamber 32; a replaceable gas cylinder 50 containing pressurized CO ₂ A gas; a gas inlet line 60 operable to fluidly connect the gas cylinder 50 to the inflator bottle interface 40; and a gas supply mechanism 70 for controlling the supply of gas from the gas cylinder 50 to the inflator bottle interface 40 via the gas inlet line 60.

The removable inflator bottle 30 includes a bottom 34 and a tapered open top 36. The inflator bottle interface 40 is pivotable to enable attachment and removal of the removable inflator bottle 30 along an axis oblique to the vertical and is configured to seal the open top 36 of the removable inflator bottle 30 when the inflator bottle 30 is fully engaged. The inflator bottle interface 40 includes a gas inlet tube 62 forming part of the gas inlet line 60, the gas inlet tube 62 being configured to extend inside the chamber 32 of the removable inflator bottle 30 when the removable inflator bottle 30 is engaged by the inflator bottle interface 40 and having a gas inlet nozzle 62A for injecting pressurized gas into the liquid contained in the chamber 32.

As shown in fig. 3, the gas supply mechanism 70 includes a valve 72 operable to selectively allow gas to flow from the gas cylinder 50; and a pivotable valve actuating member 74 driven by a gas supply mechanism solenoid 76.

In addition to the inflator station 20, the inflator device 10 includes an electronic controller 80 and two selectively activated stations: an aerated liquid dispenser station 100; a flavor dispenser station 200.

The aerated liquid dispenser station 100 comprises an aerated liquid dispenser outlet 110 for dispensing aerated liquid into a drinking container 150; a liquid outlet line 120 operable to fluidly connect the aerator bottle interface 40 to the aerator liquid dispenser outlet 110 to allow aerated liquid to flow from the chamber 32 of the removable aerator bottle 30 to the aerator liquid dispenser outlet 110; and a liquid flow controller 130 for controlling the discharge of inflation liquid from the removable inflator bottle 30 to the inflation liquid dispenser outlet 110 via the liquid outlet line 120. The liquid flow controller 130 includes a liquid flow solenoid valve 132 and a flow regulator 134.

The liquid outlet line 120 includes a dip tube 122 supported by the inflator bottle interface 40, the dip tube 122 having an opening 122A, the dip tube 122 for receiving inflation liquid at a lowermost portion of the chamber 32 when the removable inflator bottle 30 is engaged by the inflator bottle interface 40.

The flavor dispenser stage 200 comprises: a flavored liquid dispenser 210 including a flavored liquid dispenser outlet 212 and a flavored dispenser mechanism 214; a gas outlet line 220 operable to supply gas from the headspace of the removable inflator bottle 30 to the flavored liquid dispenser 210, the gas outlet line 220 comprising a gas outlet 222 disposed in the inflator bottle interface 40; a gas outlet solenoid valve 230 for controlling the discharge of gas from the removable inflator bottle 30 to the flavor dispenser mechanism 214 via the gas outlet line 220; a dump valve 232; and a pressure console 240 fluidly coupled to the gas outlet line 220 between the gas outlet 222 and the gas outlet solenoid valve 230.

The flavored liquid dispenser outlet 212 is positioned adjacent to the aerated liquid dispenser outlet 110 to allow simultaneous dispensing of flavored liquid and aerated liquid into the drinking container 150, wherein the flavored liquid dispenser outlet 212 and the aerated liquid dispenser outlet 110 are positioned to perform mixing in the air of the flavored liquid and the aerated liquid within the drinking container 150. Thereby, the need to remove the flavouring liquid from the apparatus after dispensing the flavouring liquid is minimised.

The flavor dispenser mechanism 214 includes a flavor capsule receptacle 216 for receiving a single-use flavor capsule 300 and a pressure-driven piston 218. The piston 218 is activated by the gas pressure generated in the head of the chamber 32 from the removable inflator bottle 30 during the inflation process via the gas outlet line 220 and acts as a syrup pump.

As shown in fig. 5, the flavoring capsule 300 includes: a sealed collapsible container 310 containing a flavoring syrup 320; and a cap 330 defining a container receiving portion 332 for slidably receiving the end 312 of the collapsible container 310, and a bottom portion 334 defining a central outlet 336 for dispensing the flavoring syrup 320, and at least one perforated element 338 extending from the bottom portion 334 and extending circumferentially around the central outlet 336.

Collapsible container 310 includes a flexible bladder portion 314 defining a chamber 316 for receiving a flavoring syrup 320; piston contact surface 314A; a rupturable membrane portion 318 sealing the opening of the chamber, the rupturable membrane portion 318 being located at the end 312 of the collapsible container.

The at least one perforated element 338 may include a plurality of elements circumferentially spaced around the central outlet 336 or a substantially annular cutting edge substantially surrounding the central outlet 336.

The pressure console 240 includes a gas reservoir 250 in the form of a 27ml gas reservoir chamber 252 with an associated check valve 254; a vent solenoid valve 242 operable to release the gas pressure in the chamber 32 to atmosphere; a pressure switch 244; and a safety feature in the form of a graphite rupture disc (graphite bursting disc) 246 and a mechanical pressure relief valve 248.

The electronic controller 80 may be responsive to user input to control the operation of each of the following: a gas supply mechanism solenoid 76; a liquid flow solenoid valve 132; a gas outlet solenoid valve 230; a dump valve 232; an exhaust solenoid valve 242. The pressure switch 244 is used to monitor the pressure in the chamber 32 and indicate to the system: a) When the proper carbonization pressure is reached in the chamber, the gas supply mechanism solenoid 76 is turned off; and b) opening the vent solenoid valve 242 to reduce the pressure in the chamber to a predetermined aerated liquid dispensing level.

In use, inflation liquid may be dispensed from the inflator device 10 in two different ways: the user may detach the removable inflator bottle 30 from the inflator bottle interface 40 and dispense inflation liquid from the removable inflator bottle 30 (e.g., if no flavoring is to be added, or if flavoring is to be added from a bottle of flavoring liquid), or they may maintain a sealed connection of the removable inflator bottle 30 to the inflator bottle interface 40 and activate the controller to dispense flavored or unflavored inflation liquid from the inflation liquid dispenser outlet 80. .

Upon activation of the inflator device 10, an initial inflation step begins in which the electronic controller 80 opens the gas supply mechanism solenoid 76 to inflate the liquid contained in the removable inflator bottle. Typically, this will generate a headspace pressure of 6 to 10 bar, and gas at that headspace pressure will collect into the gas reservoir chamber 252 via the open gas outlet line 220.

If dispensing from the aerated liquid dispenser outlet is not required, the removable inflator bottle may be removed at this stage and the controller will vent the reservoir chamber 252 via the dump valve 232 and vent solenoid valve 242.

If dispensing from the inflation liquid dispenser outlet is selected, the electronic controller 80 opens the vent solenoid valve 242 to reduce the headspace pressure to a preferred liquid transfer value (in this example, about 3 bar) before closing the vent solenoid valve 242 and opening the liquid flow solenoid valve 132 to allow transfer of inflation liquid from the removable inflator bottle 30 to the inflation liquid dispenser outlet 80 via the liquid outlet line 120 using the gas pressure generated in the head of the sealed chamber 32 during the inflation process. The flow regulator 104 maintains a substantially constant volumetric flow rate of the aerated liquid from the liquid dispenser outlet 80 as the aerated liquid is discharged from the removable aerator bottle 30 to the aerated liquid dispenser outlet 80. The discharge of aerated liquid from chamber 32 will continue until the head pressure is insufficient to continue the discharge.

If flavoring dispensing is selected, the electronic controller 80 additionally opens the gas outlet solenoid valve 230 in parallel with the liquid flow solenoid valve 132 to allow pressurized gas to be transferred from the gas reservoir chamber 252 to the flavoring dispenser mechanism 214 via the gas outlet line 220. Since the gas in the gas reservoir chamber 252 is substantially at the initial inflation pressure, the flavor dispenser mechanism is driven by a higher pressure than the inflating liquid dispenser. The relatively high pressure from the gas reservoir chamber 252 drives the piston 218 of the flavor dispenser mechanism 214 toward the piston contact surface 314A of the installed flavor capsule 300, thereby pushing the end 312 of the collapsible container 310 toward the bottom portion 334 of the lid 330 and thereby causing the at least one perforating element 338 to pierce the rupturable membrane portion 318 of the collapsible container 310 to allow the flavor syrup 320 to flow from the collapsible container 310 to the central outlet 336 (fig. 6A and 6B). Once the rupturable membrane portion 318 ruptures, the gas pressure continues to drive the piston 218 forward to substantially collapse the collapsible container 310 and thereby drive substantially all of the flavor syrup 320 out of the flavor liquid dispenser outlet 212 from the flavor capsule 300 (FIG. 6C). Thus, with the flavor dispenser mechanism 214 using the gas pressure to be rejected in a conventional home carbonator apparatus, a metered dose (accurate measurement of syrup to aerated liquid) can be added.

Referring to fig. 4, an example of a typical sequence of operations is provided for the case in which the dispensing from the aerated liquid dispenser outlet is selected in conjunction with the flavoring dispensing:

stage 1. Exhaust valve 242 is closed;

pause (0.2 seconds);

the gas supply valve 76 is open (the pressure sensor is set to 8 bar);

pause (0.2 seconds);

the gas supply valve 76 is closed.

Stage 2. Vent valve 242 is open (pressure drops to 3 bar);

the exhaust valve 242 is closed;

pause (0.5 seconds);

the liquid flow valve 132 is open (14 seconds);

after 3 seconds the gas outlet solenoid valve 230 opens;

the liquid flow valve 132 and the gas outlet solenoid valve 230 are closed.

Stage 3 exhaust valve 242 is opened.

Advantageously, the provision of the gas reservoir 250 allows the gas pressure for the aerated liquid dispensing and for the flavouring dispensing to be different and set to a value most suitable for different tasks. For example, in some cases, the aerated liquid dispensing step may require a lower pressure in order to ensure a desired carbonation level after the aerated liquid is dispensed. Further, the gas reservoir 250 may be sized to allow multiple charges of pressurized gas (e.g., to allow multiple flavor capsules to be used, which may be required for machines capable of accepting larger volumes of removable inflator bottles).

Fig. 7A and 7B illustrate a first alternative embodiment of a flavor capsule 300 'to be used with the modified version of the inflator device 10 of fig. 1, the flavor capsule 300' comprising: a sealed collapsible container 310 'containing a flavoring syrup 320'; and a one-piece outer sleeve/cap 330 'comprising an outer sleeve portion 331A for receiving the body portion 314' of the collapsible container 310', and a cap portion 331B defining an inner sleeve 332' for slidably receiving the end 312 'of the collapsible container 310', a bottom portion 334 'defining a central outlet 336' for dispensing the flavoring syrup 320', and at least one perforation element 338' extending from the bottom portion 334 'adjacent the central outlet 336'.

The body portion 314' of the collapsible container 310' has a folded bellows profile and defines a chamber 316' for receiving a flavoring syrup 320', a piston contact surface 314A ', and a rupturable membrane portion 318' sealed to the opening of the chamber 316', the rupturable membrane portion 318' being located at the end 312' of the collapsible container.

As shown, the cap portion 331B further includes an intermediate sleeve 333 for slidably receiving a locking flange 312A provided on the end 312' of the collapsible container, the intermediate sleeve 333 including first and second retaining members 333A, 333B having tapered profile features to enable advancement of the locking flange 312 in an advancement direction, but to prevent withdrawal of the locking flange 312 in an opposite direction, thereby retaining the collapsible container 310' in the single-piece outer sleeve/cap 330 '.

In one embodiment, the body portion 314' is made of High Performance Polyethylene (HPPE).

In one embodiment, the one-piece outer sleeve/cap 330' is made of High Density Polyethylene (HDPE).

In one embodiment, the rupturable membrane portion 318' is a welded HPPE film (e.g., welded in a process on a filling line).

Referring to fig. 8A-8C, the piston 218 of the inflator device 10 is urged toward the piston contact surface 314A 'of the installed flavor capsule 300' and the end 312 'of the collapsible container 310' is urged toward the bottom portion 334 'of the cap 330', causing the at least one perforation element 338 'to pierce the rupturable membrane portion 318' of the collapsible container 310 'to allow the flavor syrup 320' to flow from the collapsible container 310 'to the central outlet 336' (fig. 8A and 8B). Once the rupturable membrane portion 318' is ruptured, the gas pressure continues to drive the piston 218' forward to substantially collapse the collapsible container 310' and thereby drive substantially all of the flavoring syrup 320' from the flavoring liquid dispenser outlet 212 (FIG. 8C) from the flavoring capsule 300 '.

Fig. 9-14 illustrate a second alternative embodiment of a flavor capsule 400 to be used in the inflator device 10.

The flavor capsule 400 comprises a two-part form including a substantially rigid container 410 defining a chamber 420, the chamber 420 containing a flavor syrup 430; and a plunger 440 slidably mounted within the chamber 420 of the container and sealing it. The container 410 includes a proximal end 410A where an opening 422 to the chamber 420 is located; and a distal end 410B forming a bottom 412 having a cylindrical outlet nozzle 414. An air space 426 is provided in the chamber above the flavoring syrup 430 to allow the plunger 440 to move from the first position to the second position without substantially requiring any compression of the flavoring syrup.

As shown in fig. 11A-11B and 10, the container 410 and plunger 440 have interengageable portions that include a central frangible seal 450 disposed on the bottom 412 of the container 410 immediately above the outlet nozzle 414, and a central piercing element 460 disposed on the plunger 440. The frangible seal 450 is configured to form a central aperture 470 for dispensing flavoring syrup when pierced by the piercing element 460.

As shown in fig. 11A and 11B, the chamber 420 includes a tapered peripheral chamber wall 424 extending between the bottom 412 of the container 410 and the opening 422, the cross-sectional area of the peripheral chamber wall 424 decreasing with increasing distance from the opening 422.

The plunger 440 includes a head 442 including an upper surface 441, the upper surface 441 defining a piston contact surface 441A (including a raised central pin section 441B and an annular peripheral portion 442B), the piston contact surface 441A being configured to be engaged by the piston 218; and a peripheral sealing surface 444, the peripheral sealing surface 444 configured to seal the inner peripheral surface 424A of the peripheral chamber wall 424, the peripheral sealing surface 444 comprising at least one sealing ring 446. From a conical perspective, the head 442 is configured to seal against the inner peripheral surface 424A of the surrounding chamber wall 424 by deformation of the surrounding chamber wall 424.

As shown in fig. 10A-10C, the head 442 of the plunger 440 includes a pivotable partial central portion 442A having a frustoconical profile surrounding the perforated element 460 and having a periphery pivotably coupled to the annular peripheral portion 442B.

As shown in fig. 10B, advancement of the drive piston (not shown) engages the raised central plug section 441B, causing the partial central portion 442A to pivot and urge the piercing element 460 against the frangible seal 450 while the annular peripheral portion 442B remains in its initial position. Thus, with minimal resistance to the drive piston (e.g., minimal air compression, no sliding friction between the plunger 440 and the container 410), the frangible seal 450 can be broken to form the aperture 470 for dispensing the flavoring syrup 430 from the chamber 420.

As shown, the bottom 412 of the container 410 has an inner face 512A, the inner face 512A having an inclined profile operable to direct the flavoring syrup 430 toward the frangible seal 450, and the head 442 of the plunger 440 has a rear inner face 442A having a corresponding inclined profile, the rear inner face 442A of the head 442 substantially engaging the inner face 442A of the bottom 412 of the container 410 once the partial central portion 442A is moved into the advanced position, whereby in the third position.

Piercing element 460 includes: a rear bore engaging shaft 462 extending from the head 442 of the plunger 440 through the flavoring syrup 430 and toward the frangible seal 450; the front aperture forms a peg 464.

As shown, the rear bore-engaging shaft 462 and the front bore-forming pin 464 have a cross-shaped cross-section.

The rear bore engagement shaft 462 has a cross-sectional area A ₁ And frangible seal 450 includes a cross-sectional area A ₂ Is of the second cross-sectional form (wherein A ₁ <A ₂ ) Which is configured to combine with the first cross-sectional shape of the rear bore-engaging shaft 462 to create a predetermined flow gap morphology.

In the illustrated example, the first cross-sectional shape is an n-star shape (in this example, a cross shape), and as illustrated in fig. 13 and 14, the second cross-sectional shape is a planar constant diameter circular cross-sectional shape. Thus, the first and second cross-sectional shapes combine to create n substantially equally circumferentially spaced flow gaps 472 around the rear bore-engaging shaft 462 when the rear bore-engaging shaft 462 is fully engaged in the formed bore 470, one at each point of the n-sided star shape. This controls the flow of fluid out of chamber 420.

When pierced by the forward hole forming staples 464 (fig. 12D-12F), the displaceable triangular flap portion 454 will fold outwardly creating four triangular flaps and four small flow gaps 472.

In use, during an initial piercing step, a partial central portion 442A of the plunger 440 may be displaced relative to the container 410 and annular peripheral portion 442B (e.g., by passing CO ₂ Pressure driven actuation against a central peg 441B disposed on the upper surface 441) moves from a first position (fig. 10A) to a second position (fig. 10B), wherein movement of the partial central portion 442A of the plunger 440 relative to the container 410 from the first position to the second position causes the piercing element 460 to pierce the frangible seal 450 to form the aperture 470 for dispensing the flavoring syrup 430 from the chamber 420.

Once frangible seal 450 is pierced, the entire plunger 440 (with the partial central portion 442A now in the advanced position) can be moved to a third position (fig. 10C) relative to the container 410 during the discharging step, with the drive piston resting against the central plug 441B and the annular peripheral portion 442B, wherein movement of the plunger 440 relative to the container 410 from the second position to the third position pushes the flavoring syrup 430 to flow out of the chamber 420 and through the aperture 470.

In the third position, piercing element 460 extends along substantially the entire length of outlet nozzle 414 to create a central flavor stream guiding element.

The two portions 410 and 440 of the flavor capsule 400 (and the associated portions of the inflator device 10) may be designed to be made from a range of thermoplastic polymers as well as biological, biodegradable, and compostable materials.

The flavoring syrup flows down the sides of the piercing element 460 and returns to a stream of fluid as it exits the tip.

In an alternative design, the staples may not return a single jet to a single stream, thereby creating multiple fluid jets.

Once frangible seal 450 is pierced, the gas pressure continues to drive piston 218 forward to drive substantially all of flavoring syrup 430 from flavoring capsule 400 out of outlet nozzle 414.

Fig. 15 and 16 show an alternative container 410' for use in a flavor capsule 400 (common features labeled accordingly) and including an alternative frangible seal 450', wherein the planar constant diameter circular cross-sectional shape of frangible seal 450 is replaced by a frustoconical circular cross-sectional shape 450 '.

Fig. 17 and 18A-18D illustrate yet another alternative container 410 "for use in a flavor capsule 400 (again, common features are labeled accordingly) and including a frangible seal 450" for use with a piercing element having a circular cross-sectional shape. As shown, the frangible seal 450 "defines a displaceable tab profile 452 comprising a plurality n of substantially equally long and substantially equally spaced lines of weakness 452, each line of weakness being formed by a rupturable thin wall section of plastics material and extending radially from a central axis" a "to an end region 453A. The n lines of weakness 453 divide the frangible seal portion 450 into a plurality of n circumferentially spaced apart radially extending displaceable triangular flap portions 454, each displaceable triangular flap portion 454 being formed from a flexible thin wall section of plastics material and separated by the lines of weakness 453. In alternative designs, the profile of the displaceable tab may be an additional part or an overmolding combining two different materials.

Each of the plurality of n displaceable triangular flaps 454 has a reinforced edge 454A that extends along the line of weakness 453 to cause the flaps to retain their shape when the line of weakness is broken by the piercing action of the piercing element and by the reinforced hinge edge 454B formed by the reinforced region of material 455 adjacent to each hinge edge.

When pierced by the forward hole forming staples 464 (fig. 18A-18D), the displaceable triangular flap portion 454 will fold outwardly creating triangular flaps and six small flow gaps 472.

As in the previous embodiment, the flavoring syrup flows down the sides of the piercing element and returns a stream of fluid as it exits the tip.

Again, in alternative designs, the staples may not return a single jet into a single stream of fluid, thereby creating multiple fluid jets.

Fig. 19 and 20A-20B illustrate an alternative plunger 440 'to be used in a flavor capsule 400 (common features labeled accordingly) and including a partial central portion 442A' with a flexible dome profile configured to operate in the same manner as the partial central portion 442A.

Fig. 21 and 22A-22B illustrate yet another alternative plunger 440 "to be used in a flavor capsule 400 (common features labeled accordingly) and including a partial central portion 442A" with a flexible rolling winding profile configured to operate in the same manner as the partial central portion 442A.

Fig. 23A and 23B illustrate another alternative embodiment of a flavor capsule 500 to be used with the modified version of the inflator device 10 of fig. 1, the flavor capsule 500 comprising: a sealed collapsible container 510 containing a flavoring syrup 520; a cover 530; and a tearable collar 540 having a pull tab portion 542.

The cap 530 includes a flared upper portion 530A and a cylindrical lower portion 530B. Lower portion 530B defines a sleeve 532 for slidably receiving end 512 of collapsible container 510; a bottom portion 534 defining a central outlet 536 for dispensing flavoring syrup 520; and at least one perforated element 538 extending from the bottom portion 534 adjacent to the central outlet 536. The tearable collar 540 is frangibly connected to the upper perimeter 531 of the flared upper portion 530A and is configured to surround and abut the front end 514B of the main body portion 514 of the collapsible container 510.

The body portion 514 of the collapsible container 510 has a folded bellows profile and defines a chamber 516 for receiving a flavoring syrup 520, a piston contact surface 514A, and a rupturable membrane portion 518 sealed to the opening of the chamber 516, the rupturable membrane portion 518 being located at the end 512 of the collapsible container.

As shown, inner sleeve 532 and end 512 include cooperating retaining members 550A, 550B (e.g., protruding annular ribs) to enable end 512 to be advanced in an advancement direction, but to prevent end 512 from being withdrawn in the opposite direction, thereby retaining collapsible container 510 in cap 530.

As shown with reference to fig. 24A-24C, the tearable collar 540 must first be removed (e.g., by a user pulling on the pull tab portion 542) to enable the end 512 of the collapsible container 510 to be advanced toward the at least one piercing element 538. Thereby, accidental actuation of the flavor capsule 500 during transportation or dropping can be prevented. The tearable collar 540 may also act as a tamper-resistant feature.

In one embodiment, the body portion 514 and the cover 530 are made of Medium Density Polyethylene (MDPE).

In one embodiment, rupturable membrane portion 518 is a heat-sealed membrane (e.g., heat sealed in a process on a filling line).

In one embodiment, the flavor capsule 300, 300', 400, 500 may include a bar code, and the electronic controller 80 is operable to select dispensing parameters (e.g., a desired degree of aeration and/or volume of water) based on the bar code (e.g., using a bar code reader module) to provide further increased flavor doses.

Fig. 25 illustrates an alternative portable home inflator device 10 'for preparing an inflated beverage based on the inflator device 10 (common features are labeled accordingly) in accordance with another embodiment of the invention in which the capsule 300 and associated capsule dispenser portion are replaced by a removable bulk container 600 with an integral bulk container dispenser module 610 incorporating a flavored liquid outlet 212'. In addition, an optional low pressure air pump 260 is connected to the gas outlet line 220 'via a check valve 262 to provide a constant flow of low pressure gas to the headspace of the chamber 32' during the dispensing phase to transfer inflation liquid from the removable bottle 30 'to the inflation liquid dispenser outlet 110'.

The bulk container 600 includes a vented, fixed volume (e.g., non-collapsed) bottle 602 having a neck 604. The bulk container 600 may provide multiple measurements of flavoring syrup over multiple uses of the inflator device 10'. Because the bulk container dispenser module 610 and the flavored liquid outlet 212' are integrated into the container, bulk containers of different flavors can be easily exchanged without risk of flavor contamination. In general, the bulk container 600 may be a simple plug-in device. Since the pressure at the bulk container interface is substantially balanced, no retention feature is required.

As shown in fig. 26A and 26B, the bulk container dispenser module 610 includes an upper cover portion 620 and a lower housing 630 configured to engage a bulk container receptacle 270 supported by the housing 12', the bulk container receptacle 270 including a bottom 270A and an upstanding annular wall 270B extending from the bottom.

The upper cap portion 620 includes a collar 620A configured to receive the neck 604 and bottom portion 620B of the bottle 602. The bottom portion 620B defines a plurality of inlet apertures 622 associated with a non-return inlet flap valve 623 for allowing the flavoring syrup to flow out of the bottle 602 under gravity; and a gas conduit 624 extending from a radially outermost gas inlet 626 to a raised central gas outlet 628, which is associated with a gas outlet valve 629. An annular seal 621 seals the connection between the bottle 602 and the cap portion 620.

Lower housing 630 includes a cylindrical upper housing section 632 defining a metering chamber 634 configured to receive flavoring syrup from bulk container 600 via inlet aperture 622; and a reduced diameter cylindrical nozzle housing 636 configured to engage the aperture 274 disposed in the bottom 270A of the bulk container receptacle 270. Nozzle housing 636 also defines a gas conduit 670 extending between gas inlet 672 and metering chamber 634.

A central shaft 650, including a narrow diameter forward end 650A and a wide diameter rearward end 650B, is supported by upper cover portion 620 and extends centrally through metering chamber 634. The nozzle housing 636 defines a central bore 638 for receiving the front end 650A of the central shaft 650. The central shaft 650 defines a central passage 652 extending between an inlet port 654 and an outlet port 656.

Mounted to central shaft 650 is a flexible silicone diaphragm member 700, which flexible silicone diaphragm member 700 includes an upper diaphragm portion 710 received in metering chamber 634 and a lower diaphragm portion 720 received in bore 638.

Upper diaphragm portion 710 is coupled to a lower end of rear end 650B of central shaft 650 and is coupled to an upper periphery of metering chamber 634.

The lower diaphragm portion 720 forms a pressure actuated sleeve valve 722 covering the outlet port 656 and includes an end 730 defining an outlet nozzle 740, the outlet nozzle 740 serving as the flavored liquid outlet 212'.

As shown, the output nozzle 740 and sleeve valve 722 formed by the lower diaphragm portion 720 and the upper diaphragm portion 710 are formed as a single continuous piece of flexible silicone.

Upper diaphragm portion 710 is movable within metering chamber 634 between a retracted position (shown in fig. 27D) and an advanced position (shown in fig. 27F), wherein movement from the retracted position to the advanced position forces flavoring syrup received in metering chamber 634 into inlet port 654 and through central passageway 652 to outlet port 656, pressure-activated sleeve valve 722 on outlet port 656 allowing flavoring syrup to be dispensed through outlet nozzle 740. Movement of upper membrane portion 710 from the advanced position to the retracted position allows flavoring syrup from bottle 602 to enter metering chamber 634.

The annular wall 270B of the bulk container receptacle 270 defines an open-top CO ₂ A collector region 272 (e.g., a cask opening region) surrounding the bulk container dispenser module 610 and configured to receive the bulk container module via CO connected to the venturi nozzle 280 ₂ The feed tube 274 receives CO from the removable bottle 30' during the vent cycle ₂ . The venturi nozzle 280 is configured to receive flow from the removable inflator bottle 30' to the CO during the exhaust cycle ₂ The gas of the collector region 272 and includes an upstream tap 282 connected to a gas inlet 672. Via CO ₂ Feed line 274 enters CO ₂ The exhaust gas from the collector region 272 floods the environment surrounding the gas inlet 626 of the dispenser module 610, whichWhen metering chamber 634 is filled with flavoring syrup, CO is allowed to be fed via gas line 624/gas outlet 628 ₂ Pulled into the bottle 602. By virtue of the open top, excess CO ₂ Will be from CO ₂ The collector area 27 overflows to atmosphere to avoid pressure build-up in the bottle 602. Although CO is shown in this example ₂ Spills, but simple aeration venting is also possible (e.g., where the flavoring syrup in the bottle 602 is suitable for prolonged exposure to air).

In operation, the inflator device 10 'provides the same functionality as the inflator device 10 (e.g., is capable of dispensing inflation liquid directly from a removable inflator bottle 30' or via an inflation liquid dispenser outlet 80', and optionally flavoring through a flavoring liquid outlet 212'). However, as shown in fig. 27A to 27F, the gas circulation is modified in consideration of the change in the internal structure.

In step 1 (fig. 27A), the system is stationary with the upper diaphragm portion 710 in the advanced position. The vent solenoid valve 242' is open and the connection of the gas reservoir 250' via the 3/2 gas outlet solenoid valve 230' is closed.

In step 2 (fig. 27B), the vent solenoid valve 242' is closed while the system is carbonation. During this step, pressurized CO from the headspace of the removable inflator bottle 30 ₂ Is transferred to the gas reservoir 250' for later use in dispensing flavoring syrup. The connection of the gas reservoir 250 'via the 3/2 gas outlet solenoid valve 230' remains closed to prevent release of pressurized CO from the gas reservoir 250 ₂ 。

In step 3 (fig. 27C), when the system performs a vent cycle, the vent solenoid valve 242 'opens to reduce the pressure in the headspace of the removable inflator bottle 30' to a lower pressure (in this case to approximately atmospheric pressure, since dispensing inflation liquid will use the gas pressure supplied by the gas pump 260). When discharging CO ₂ Upon passing through venturi nozzle 280, the venturi nozzle 280 creates a negative pressure at upstream tap 282 to draw upper diaphragm portion 710 into a retracted position, filling metering chamber 634 with flavoring candyAnd (3) pulp. Furthermore, the connection of the gas reservoir 250 'via the 3/2 gas outlet solenoid valve 230' remains closed to prevent release of pressurized CO from the gas reservoir 250 ₂ . In the case of multiple carbonation cycles, the vent solenoid valve 242' may be activated between carbonation cycles and at the end of carbonation.

In step 4 (fig. 27D), the vent cycle is complete and metering chamber 634 is filled with an amount of flavoring syrup.

In step 5 (fig. 27E), the system dispenses with an air pump 260 that applies low pressure air to the headspace of the removable inflator bottle 30' to push inflation liquid upward through dip tube 122' to inflation liquid dispenser outlet 80'. In this dispensing mode, the vent solenoid valve 242' is closed and the connection of the gas reservoir 250' via the 3/2 gas outlet solenoid valve 230' is opened to allow stored pressurized CO from the gas reservoir 250 ₂ Flows into the metering chamber 640 via the gas inlet 672. This positive air pressure from the air reservoir 250 'collapses the upper membrane portion 710 and forces the flavoring syrup out through the outlet nozzle 740 to combine with the aerated liquid via the aerated liquid dispenser outlet 80'. This flavoring syrup dispensing action continues until metering chamber 634 is emptied and upper diaphragm portion 710 returns to the retracted position.

In step 6 (fig. 27F), the dispensing process is completed and the system returns to a rest state, wherein the vent solenoid valve 242' is reopened and the connection of the gas reservoir 250' via the 3/2 gas outlet solenoid valve 230' is closed.

Thus, a system is provided wherein stored gas from gas reservoir 250' is used to collapse upper membrane portion 710 and dispense flavoring syrup received in metering chamber 634, wherein CO is expelled after the carbonation cycle ₂ Is used to refill bottle 602 and create a reduced pressure in metering chamber 634 by way of venturi nozzle 280 to suck diaphragm portion 710 down and refill the metering chamber.

In one embodiment, the removable bulk container 600 is configured to be installed in the bulk container receptacle 270 in a predetermined orientation (e.g., to prevent accidental disconnection of the bottle from the dispenser when assembled to the machine). In one example, the bottle 602 may have a substantially cylindrical profile with a single planar portion (e.g., an anti-rotation portion). The bottle 602 may be configured to be mounted in the bulk container receptacle in a single orientation relative to the housing 12'. This also allows the orientation of the bottle 602 to be adapted to "intelligently" read product data (e.g., bar codes read by the electronic controller 80') to set the carbonation level and volume of water for the finished beverage.

As an alternative to the fixed volume bulk container 600 described above, a simplified version of the bulk container dispenser module 610 may be used with a variable bulk container (e.g., a bag or collapsible bottle) in which a gas inlet into the bottle may be omitted.

Fig. 28A shows an example of a first alternative bulk container dispenser module 610' including a simple central sealing plug to be used with a variable volume container.

Fig. 28B illustrates an example of a second alternative bulk container dispenser module 610 "including a film perforation element 680 to be used with a variable volume container including a film 608 for aseptically filled products.

As should be appreciated, the portable home inflator apparatus 10, 10' provides significant enhancement and flexibility as compared to conventional home carbonators, while being substantially powered by the gas pressure available in the headspace of the conventional home carbonator apparatus. Thereby providing enhanced points and more flexibility with minimal additional complexity and inflator device costs.

the end of the collapsible container is movable relative to the cap from a first position to a second position, wherein movement of the end from the first position to the second position causes the at least one perforating element to pierce the collapsible container; and

a front portion of the end of the collapsible container is received in the inner sleeve when the collapsible container is in the first position, and the end is configured to advance further into the inner sleeve when the collapsible container is moved from the first position to the second position.

55. The capsule of any one of claims 43 to 54, wherein the collapsible container comprises a body defining a folded bellows profile.

56. A capsule, comprising:

a container defining a chamber for containing a fluid to be dispensed; and

a plunger sealing the chamber of the container, the plunger being movable relative to the container between a first position and a second position;

wherein the container and the plunger have interengageable portions comprising a frangible seal portion and a piercing element, the frangible seal portion being configured to form at least one aperture in the container when pierced by the piercing element for dispensing the fluid from the chamber;

wherein, in use, relative movement of the plunger with respect to the container from the first position to the second position causes the piercing element to pierce the frangible seal to form the at least one aperture;

wherein movement of the plunger relative to the container from the first position to the second position occurs in a direction of advancement and the plunger is further movable relative to the container in the direction of advancement between the second position and a third position, wherein movement of the plunger relative to the container from the second position to the third position reduces the volume of the chamber defined by the container and the plunger and pushes the fluid out of the chamber and through the at least one aperture;

Wherein the movement of the plunger relative to the container from the first position to the second position comprises relative movement of a partial portion of one of the plunger or container relative to an adjacent portion of the one of the plunger or container.

57. The capsule of claim 56, wherein the portion is a central portion and the adjacent portion is a surrounding outer portion.

58. The capsule of claim 56 or 57, wherein movement of the plunger relative to the container from the second position to the third position comprises movement of at least the adjacent portion of the one of the plunger or container.

59. The capsule of any one of claims 56 to 58, wherein the partial portion is disposed on the plunger.

60. The capsule of any of claims 56 to 59, wherein the piercing element is disposed on the partial portion.

61. The capsule of any of claims 56 to 60, wherein the partial portion comprises a advanceable member coupled to the adjacent portion.

62. The capsule of claim 61, wherein the advanceable member comprises a pivotable or flexible member.

63. The capsule of any one of claims 56 to 62, wherein the frangible seal is disposed on the container.

64. The capsule of any one of claims 56 to 63, wherein:

when the plunger moves relative to the container from the first position to the second position, the segment moves relative to the adjacent segment from a retracted position to an advanced position; and

when the part is in the advanced position, the plunger and the opposing inner face of the bottom of the container are configured such that the inner face of the plunger substantially engages the inner face of the bottom of the container.

65. The capsule of any one of claims 56 to 64, wherein the piercing element comprises:

a front hole forming portion;

a rear aperture engagement portion.

66. The capsule of claim 65, wherein the rearward bore engaging portion and the frangible sealing portion of the piercing element comprise first and second cross-sectional shapes configured such that when the rearward bore engaging portion is engaged in the bore formed by the forward bore forming portion piercing the frangible sealing portion, the first and second cross-sectional shapes combine to create at least one flow gap around the rearward bore engaging portion.

67. The capsule of claim 66, wherein the first and second cross-sectional shapes combine to create a predetermined pattern of n flow gaps around the rear aperture engagement portion, the n flow gaps together forming an outlet for the fluid to flow through.

68. The capsule of claim 67, wherein the first cross-sectional shape is in the form of a substantially circular shape and the second cross-sectional shape is in the form of an n-star or an n-sided polygon.

69. The capsule of any of claims 56 to 68, wherein the capsule further comprises an outlet nozzle disposed downstream of the frangible seal and operable to receive fluid from the at least one aperture.

70. The capsule of claim 69, wherein in the third position, a front portion of the piercing element extends substantially along the entire length of the outlet nozzle to create a central fluid directing element.
