The invention relates to a beverage transfer device and a method of transferring a beverage.
Some alcoholic beverages age after bottling, allowing certain flavour characteristics to develop. Wines in particular can be stored to allow air inside the bottle to react with and age the wine over time. Wine stored in corked bottles also age due to the cork being permeable allowing the slow ingress of air into the bottle. This ageing process has to be tightly controlled to prevent over oxidation of the wine with the associated adverse ageing effects, such as discolouration and the acquisition of unwanted aromas. Wines therefore have a limited shelf life and an optimum window in which to be consumed.
Once a bottle has been opened, the exposure of the wine to fresh air causes new oxidation that further alters the characteristics of the wine. Over exposure to air following opening can cause the wine to lose the aromas and flavours, which give the wine its preferential character.
The present invention provides a device or apparatus for transferring a beverage from a sealed container into a storage vessel, a method of transferring a beverage from a sealed container into a storage vessel, and a method of operating the device or apparatus for transferring a beverage from a sealed container into a storage vessel.

The method includes:
These and other objects, advantages and features of the invention will become apparent upon review of the following specification in conjunction with the drawings.
Embodiments of the invention will now be described, by way of example only, with reference to accompanying drawings, in which:
The present invention provides apparatus for transferring a beverage from a sealed bottle to a storage vessel. The apparatus is designed as a closed system to prevent the beverage mixing with air from outside the bottle during the transfer process. The storage vessel, once filled is sealed and airtight. This invention finds particular application with beverages—such as wine—stored in bottles having a permeable cork/synthetic cork stopper which allow the beverage to age continuously due to the slow ingress of air permeating through the stopper. It is intended that, when a beverage has reached its optimum condition in the ageing process, the apparatus may be operated to transfer the beverage into the storage vessel and thereby allow the long-term storage of the beverage at its optimum condition, without any degradation in condition due to continued ageing. The present invention also allows the beverage to be transferred to multiple storage vessels to allow individual portions to be consumed at different times. This is to be compared with opening a bottle and consuming the beverage from the bottle over a period of time, in which time the beverage will have degraded.
In some embodiments, the aperture 29 is provided in a longitudinal wall 30 of the second needle 8. The aperture 29 is configured to allow inflation of the bladder 9 radially about the second needle 8 so that the bladder 9 expands outward and into contact with sides of the bottle 5 on inflation. The aperture 29 may comprise multiple apertures 29 arranged about the circumference and/or along the length of the second needle 8. For example, four apertures 29 may be provided spaced 90 degrees apart. Preferably, each aperture 29 may be elongate and extend in a longitudinal direction of the second needle 8.
In some embodiments, the aperture 29 may be provided in the tip of the second needle 8.
In some embodiments, the bladder 9 comprises multiple bladders 9, each bladder 9 being configured to expand from within the cavity 11 out of a respective aperture 29. In such embodiments, the bladders 9 may each comprise a flexible membrane that extends across a respective aperture 29, the pump 10 being configured to pressurise the cavity 11 to cause expansion of the bladders 9 out of the apertures 29.
In some embodiments, the bladders 9 are separately connected to the pump by a corresponding pipe running from the pump 10 and into the cavity 11. Advantageously, this allows each bladder 9 to be separately pressurised, allowing the bladders 9 to be inflated at different times.
The apparatus 1 may further comprise a clamp (not shown) to hold the beverage container 5 in an inverted or angled orientation during use of the apparatus. In the illustrated embodiments, the beverage container 5 comprises a bottle having a neck portion 13 and a wider body portion 14. The clamp may be configured to grip the neck 13 or the body 14 of the bottle 5. It shall be appreciated however that the clamp may be configured to grip a container of any shape or size.
The first needle 2 comprises a pin 15 slideably disposed within the conduit 4, as shown in
In use, the bottle 5 is clamped in position. The first and second needles 2, 8 are inserted into the bottle 5 through the stopper 12 and a storage vessel 6 is connected to the first needle 2. To transfer the beverage from the bottle 5 to the storage vessel 6, the pin 15 is drawn down the conduit 4 of the first needle 2 while the bladder 9 simultaneously inflated by the pump 10. The inflation of the bladder 9 and the movement of the pin 15 causes the beverage to be displaced along the conduit 4.
Openings 18 in the first needle 2 allow the beverage to flow between the conduit 4 and the storage vessels 6 connected thereto. The pin 15 acts as a valve to open and close the openings 18. When the pin 15 is positioned over an opening 18, the beverage is blocked from passing out of the opening 18 and into the corresponding storage vessel 6. Therefore, the storage vessels 6 connected to the first needle 2 are filled sequentially by movement of the pin 15 along the conduit 4 as each opening 18 is unblocked in turn.
The first storage vessel 6a may be a sample vessel 6a to allow a sample of the beverage to be extracted and tested before the second storage vessel 6b is filled. Advantageously, any air in the bottle 5 is captured by the sample vessel 6a to prevent the air being introduced into the second storage vessel (or indeed any further storage vessels that are connected to the first needle 2) that might cause further ageing of the beverage.
It shall be appreciated that the use of a pin 15 inside the first needle 2 prevents air being introduced into the bottle 5 when the first needle 2 is inserted through the stopper 12. This is because the pin 15 occupies the volume inside the conduit 4 that would otherwise be occupied by air. The seal 16 is provided adjacent the tip of the pin 15 so that the beverage is prevented from flowing between the pin 15 and the conduit 4.
The aperture 22 is configured to allow inflation of the bladder 9 radially about the first needle 2 so that the bladder 9 expands outward and into contact with sides of the bottle 5 on inflation. The aperture 22 may comprise multiple apertures arranged about the circumference and/or along the length of the needle 2. For example, four apertures 22 may be provided spaced 90 degrees apart. Preferably the apertures 22 are spaced from the upper end of the needle 2 so that the bladder 9 expands to displace the beverage toward the upper end and the inlet 3. Preferably, each aperture 22 may be elongate and extend in a longitudinal direction of the needle 2.
In a third embodiment illustrated by
In a fourth embodiment, a particular example of which is illustrated by
To operate the apparatus of the fourth embodiment, the bottle 5 is held by a clamp 32 in an inverted orientation and the first needle 2 is inserted through the stopper 12. Where the first needle 2 comprises the second conduit, gas is introduced into the bottle 5 through the first needle 2 to pressurise the bottle and displace the beverage and pin 15 along the first conduit 4, filling the storage vessels as described above. The second needle 8 may be omitted entirely. Alternatively, and as illustrated by
In some embodiments, a spring (not shown) may be provided at a bottom end of the conduit 4 to bias the pin 15 toward the inlet 3. The force of the spring may be calibrated so that pressurisation mechanism 7 displaces the pin 15 with the beverage along the conduit 4. It shall be appreciated that when the pin 15 uncovers each opening, the force on the pin 15 drops as the flow of beverage is directed into the corresponding storage vessel 6, preventing further displacement of the pin 15 until the storage vessel 6 is at capacity. In this way, the spring controls the movement of the pin 15 so that an opening 18 is only uncovered when the storage vessel 6 associated with the preceding opening 18 is full.
In some embodiments, the inlet 3 is provided in a longitudinal wall of the first needle 2. Therefore, the inlet is not blocked by any material dislodged by insertion through the stopper 12. Such an arrangement is shown in
In some embodiments, the apparatus may comprise an actuator (not shown) to control the movement of the pin 15 along the conduit. For example, the actuator may include an electrically driven pinion gear that drives a linear gear on the pin 15 in the manner of a rack and pinion system. A controller may coordinate operation of the pinion gear so that the pin 15 is displaced at a rate corresponding to operation of the displacement mechanism 7. Therefore, the displacement mechanism 7 and pinion gear may act simultaneously so that the bottle 5 is pressurised as the pin 15 is displaced by the pinion gear. The actuator may be configured to hold the pin 15 in a position for a period while a storage vessel 6 is filled. For example, the actuator may be configured to hold the pin 15 in the first position shown in
In some embodiments, the connector 17 comprises a screw connector as shown in
Although the connector 17 illustrated by
In each of the above-described embodiments, when the first needle 2 is inserted through the stopper 12 and connected to a storage vessel, the apparatus provides a closed system that prevents the beverage from mixing with air outside of the bottle 5.
In some embodiments a vacuum pump may be fluidly connected to the conduit 4 to remove any residual air in the connectors 17, storage vessels 6 and transfer pipe 23 (where present). The pump may be operated once a closed system has been made in the manner described. Therefore, during the transfer process, the beverage is prevented from coming into contact with any air outside of the bottle 5.
The particular example of
A vacuum pump 33 is connected to four storage vessels 6. Each storage vessel 6 is a quarter bottle comprising a stopper 40. A pin 41 is inserted through each stopper 40 to allow air to be drawn out of the storage vessel 6 through the pin 41 by the vacuum pump 33. To achieve this, each pin 41 is fluidly connected to the vacuum pump 33 by a vacuum line 34. The vacuum line 34 comprises sub lines 42 connected to each pin 41 and a manifold 35, which connects the sub lines 42 to a main line 43. The main line 43 in turn connects the manifold 35 to the vacuum pump 33.
As in the third embodiment, the example of
In the example of
The first three-way control valve 36 is set in a first position to connect the transfer pipe 23 to the bypass pipe 37, closing off the first needle 2.
The second three-way control valve 38 is set to first position to connect the reservoir 31 to the bypass pipe 37, closing off the second needle 8.
The vacuum pump 33 is activated to draw air out of the storage vessels 6, manifold sections 24, transfer pipe 23 and bypass pipe 37. This causes inert gas to be drawn from the reservoir 31 and into the bypass pipe 37, transfer pipe 23, manifold sections 24 and storage vessels 6, thereby flushing inert gas through each of the bypass pipe 37, transfer pipe 23, manifold sections 24 and storage vessels 6.
The vacuum pump 33 is deactivated; the first three-way control valve 36 is set in a second position to connect the transfer pipe 23 to the first needle 2, closing off the bypass pipe 37; and the second three-way control valve 38 is set in a second position to connect the reservoir 31 to the second needle 8, closing off the bypass pipe 37. This causes inert gas to pressurize the bottle 5, displacing the beverage from the bottle 5, along the transfer pipe 23 and manifold sections 24 and into the storage vessels 6.
Once the storage vessels 6 are full, the second three-way control valve 38 is set to a third position to isolate the reservoir 31 from the second needle 8 and the bypass pipe 37. The pins 41, 44 are removed from the stoppers 40 of the storage vessels 6 to allow the storage vessels 6 to be separated from the system.
It shall be appreciated that the stoppers 40 are self-sealing so that, on removal of the pins 41, 44, the storage vessels 6 are completely air tight.
The system may be reused by attaching new empty storage vessels 6 and repeating the steps above.
While the example of
Furthermore, while the example of
Furthermore, while the above embodiments describe and illustrate transferring a beverage from a single sealed container 5, it will be appreciated that minor modification of the apparatus will allow the simultaneous transfer of beverage from a plurality of sealed containers 5. This may mean the transfer from a plurality of sealed containers 5 into a single storage vessel 6 (as illustrated in
By providing a closed system, the beverage is transferred to the storage vessel 6 without introducing fresh air into the bottle that could cause further ageing or oxidation. The beverage may therefore be stored having the exact same flavour characteristics developed in the bottle. This allows the beverage to be stored when it has aged to an optimum flavour condition without the beverage to surpassing the optimum condition by over-ageing. Furthermore, the beverage may be stored in multiple storage vessels 6 to allow individual portions to be consumed at different times, while each portion provides the exact same quality and taste experience. This is to be compared with opening a bottle and consuming the beverage from the bottle over a period of time, in which time the beverage will have degraded.
In some embodiments, the storage vessel 6 comprises a flexible bag that is vacuum sealed prior to connection to the apparatus 1. By vacuum sealed, it is meant that air is pumped out of the bag so that atmospheric pressure compresses each side of the bag together. A screw cap may be attached to the spigot 26 (where one is provided) to prevent any ingress of air prior to use. In some embodiments, the spigot is attached to a neck portion of the bag that is configured to be heat sealed. In particular, the neck portion may be placed between two heated plates following detachment from the connector 17 to cause the neck portion to fuse. The bag may be made from a polymer material. The storage vessel 6 may further comprise a cardboard outer box (not shown) to house the flexible bag for ease of storage.
In some embodiments, the apparatus further comprises a filter (not shown) to prevent any sediment that is present within the container 5 from passing into the storage vessels 6. The filter may be provided in any part of the system between the inlet 3 and the storage vessels 6. For example, the filter may be provided over the inlet 3 or across any of the openings 18 of the first needle 2.
The storage vessel 6 may be any capacity required. For example, the storage vessel 6 may equal the capacity of the bottle 5, or the storage vessel may be smaller, for example, where the storage vessel 6 is configured as a sample vessel.
In the embodiments described herein, the term ‘stopper 12’ is used to describe any plug that seals the container/bottle 5 and that is capable of forming a seal around the first and second needles 2, 8 when they are inserted through the stopper 12. By ‘seals the container’, it is meant that the stopper 12 prevents the beverage from leaking out of the container 5 and does not preclude the stopper 12 being permeable to air. Indeed, generally the invention is intended for use with permeable stoppers 12 that allow the slow ingress of air for ageing. Typically, the stopper 12 will be a cork or a synthetic cork, as commonly used with wine bottles or spirit bottles. However, to allow the invention to be used with screw cap bottles that do not comprise a stopper 12 that will provide a suitable seal around the needles 2, 8, an additional stopper 28 may be provided as part of the apparatus, as shown in
In the embodiments described herein, the term ‘beverage’ is meant to encompass any liquid that may be transferred from a sealed container to a storage vessel in the manner described. The apparatus finds particular application in the transfer of wine for all the reasons given, but other examples might include spirits such as whiskey and the like.
Changes and modifications in the specifically-described embodiments may be carried out without departing from the principles of the present invention, which is intended to be limited only by the scope of the appended claims as interpreted according to the principles of patent law including the doctrine of equivalents.
