This invention relates generally to the transfer of fluids from a source beverage container to a destination container, e.g., without exposing the beverage to air or other environmental conditions.
One or more embodiments in accordance with aspects of the invention allow a user to transfer or otherwise extract a beverage, such as wine, from within a bottle that is sealed by a cork, plug, elastomeric septum or other closure without removing the closure. In some cases, removal of beverage from such a bottle may be performed one or more times, yet the closure may remain in place during and after each beverage extraction to maintain a seal for the bottle. Thus, the beverage may be transferred from the bottle multiple times and stored for extended periods between each transfer with little or no effect on beverage quality. Also, the beverage can be transferred into a destination container such that the beverage is not exposed to air or other environmental conditions. Thus, in some embodiments, little or no gas, such as air, which is reactive with the beverage, may be introduced into either the source or destination container either during or after transfer of beverage from the source to the destination container. Thus, in some embodiments, a user may withdraw wine from a wine bottle without removal of, or damage to, the cork, and without allowing air or other potentially damaging gasses or liquids entry into the bottle, and the wine can be transferred to another container which receives and holds the wine without exposing the wine to air or other potentially damaging gasses or liquids.
In some embodiments, a system for transferring beverage from a source container to a destination container includes a first transfer head configured to sealingly engage with an opening of the source container to deliver gas into an interior space of the source container and to receive beverage from the source container. A second transfer head may be configured to sealingly engage with the destination container to deliver the beverage from the source container into an interior space of the destination container, and a support can be configured to support the first and second transfer heads and to support the source container with the opening of the source container positioned below a bottom of the source container. In some cases, the first transfer head can be mounted to pivot relative to the support, e.g., about a horizontal axis and/or so that the source container can be engaged with the first transfer head and remain movable relative to the support. In some cases, the second transfer head can be fixed to the support and the first transfer head can be pivotally mounted to the second transfer head and thus pivotally mounted to the support.
In some embodiments, the first transfer head can include at least one needle configured to penetrate through a closure such as a cork in the opening of the source container to deliver gas into the interior space of the source container and to receive beverage from the source container. Similarly, the second transfer head can include at least one needle configured to penetrate through a closure in the opening of the destination container to deliver gas into the interior space of the destination container to purge the destination container and to deliver beverage from the source container to the destination container.
In some cases, a first gas pathway can be fluidly coupled to the first transfer head and include a pressurize valve configured to deliver pressurized gas into the source container to pressurize the interior space of the source container. A second gas pathway can be fluidly coupled to the second transfer head and include a sparge valve configured to deliver pressurized gas into the destination container. A beverage pathway can be fluidly coupled between the first and second transfer heads and include a beverage valve configured to control delivery of the beverage from the source container to the destination container via the beverage pathway. The pressurize, sparge and beverage valves can be operated to purge the destination container of air and transfer beverage from the source to the destination container.
In some embodiments, a destination container support can be configured to move the destination container relative to the second transfer head and sealingly engage the destination container with the second transfer head. Thus, for example, engagement and/or disengagement of the second transfer head with the destination container can be automated, e.g., based on movement of the destination container support.
In some cases, a beverage pathway fluidly can be coupled between the first and second transfer heads and configured to deliver beverage from the source container to the destination container. Beverage flow along the beverage pathway can be driven only by gravity and pressure in the interior space of the source container. In some embodiments, a beverage valve can be configured to control delivery of the beverage from the source container to the destination container via the beverage pathway.
In some embodiments, a system for transferring beverage from a source container to a destination container includes a first transfer head with a gas inlet configured to receive pressurized gas, first and second gas outlets to deliver gas received at the gas inlet, and a first beverage pathway configured to transfer beverage with a first container. The first transfer head can be configured to engage with the first container to fluidly couple the first gas outlet and the first beverage pathway with an interior space of the first container, e.g., to deliver beverage from the first container. A second transfer head can include a gas inlet, a gas outlet, and a second beverage pathway configured to transfer beverage with a second container. The second transfer head can be configured to engage with the second container to fluidly couple the gas outlet and the second beverage pathway with an interior space of the second container. A gas line can connect the second gas outlet of the first transfer head to the gas inlet of the second transfer head, and a beverage line can connect the first and second beverage pathways to transfer beverage between the first transfer head and the second transfer head. In some cases, the first gas outlet and the first beverage pathway can be connected to at least one needle configured to deliver gas into the first container and transfer beverage with the first container. The at least one needle can include a first needle connected to the first gas outlet and a second needle connected to the first beverage pathway with the first and second needles configured to penetrate through a closure of the first container to position distal ends of the first and second needles in an interior space of the first container. In some cases, the first container can be the destination container and the second container can be the source container, and the beverage line can be connected to the second beverage pathway to deliver beverage from the source container to the destination container via the first beverage pathway.
In some cases, the gas outlet of the second transfer head and the second beverage pathway can be connected to at least one needle configured to deliver gas into the second container and transfer beverage with the second container. The at least one needle can include a first needle connected to the gas outlet of the second transfer head and a second needle connected to the second beverage pathway with the first and second needles configured to penetrate through a closure of the second container to position distal ends of the first and second needles in an interior space of the second container.
In some embodiments, wherein the first and second transfer heads can be connected to each other and configured to engage with the first and second container, respectively, with one of the first and second containers positioned above the other of the first and second containers. For example, the first and second transfer heads can be pivotally connected together.
In some cases, the system can include a first gas valve configured to control gas flow from the gas inlet of the first transfer head to the first gas outlet to introduce gas into the first container, a second gas valve configured to control gas flow from the gas inlet of the first transfer head to the second gas outlet to introduce gas into the second container via the gas outlet of the second transfer head, and/or a beverage valve configured to control flow of beverage through the beverage line. In some cases, the first container is a destination container, the second container is a source container, and the first gas valve can be configured to open to deliver gas from the gas inlet to the destination container to replace air in the destination container with gas from the gas inlet. The second gas valve can be configured to open to deliver gas from the gas inlet to the source container to pressurize the source container and cause beverage flow from the source container to the destination container via the first beverage pathway, the beverage line and the second beverage pathway. The beverage valve can be configured to open to permit beverage flow from the source container to the destination container and to close to stop beverage flow from the source container to the destination container.
In some cases, a container support can be configured to support and move the first or second container into engagement with the first or second transfer head. For example, the container support can be configured to support and move the first container into engagement with the first transfer head, where the first container has a closure and the first transfer head includes at least one needle fluidly coupled to the first gas outlet and the first beverage pathway. The container support can be configured to move the first container such that the at least one needle penetrates through the closure. In some cases, the at least one needle can be configured to vent an interior space of the first container when pressurized gas is delivered into the first container via the first gas outlet.
In some embodiments, the first transfer head can be configured to sealingly couple the first gas outlet and the first beverage pathway with the interior space of the first container suitable to prevent ambient atmosphere from entering the interior space of the first container, and/or the second transfer head can be configured to sealingly couple the gas outlet of the second transfer head and the second beverage pathway with the interior space of the second container suitable to prevent ambient atmosphere from entering the interior space of the second container.
In some embodiments, a method for transferring beverage from a source container to a destination container includes delivering pressurized gas into an interior space of the destination container while venting the interior space so as to replace air in the interior space with the pressurized gas, fluidly coupling an interior space of the source container to an interior space of the destination container using a beverage pathway, and delivering pressurized gas into the interior space of the source container while preventing fluid from leaving the interior space so as to pressurize the interior space of the source container. Delivery of pressurized gas into the interior space of the source container can be stopped, and beverage permitted to flow from the source container to the destination container via the beverage pathway after stopping delivery of pressurized gas into the interior space of the source container. Flow of the beverage via the beverage pathway can be driven by pressure in the interior space of the source container.
In some cases, delivering pressurized gas into the interior space of the destination container can include operating a purge valve to deliver the pressurized gas to the interior space of the destination container via a gas conduit that is sealingly engaged with the destination container. In some embodiments, delivering pressurized gas into the interior space of the destination container can include inserting a needle through a closure of the destination container, where the pressurized gas is delivered into the interior space of the destination container via the needle. In some cases, fluidly coupling the interior space of the source and destination containers can include inserting at least one first needle through a closure of the destination container and at least one second needle through a closure of the source container with the at least one first and second needles being fluidly coupled together to define the beverage pathway. The at least one first needle can include a first needle that defines part of the beverage pathway, and pressurized gas can be delivered into the interior space of the destination container via the first needle.
In some embodiments, a pressurize valve can be operated to deliver pressurized gas to the interior space of the source container via a gas conduit that is sealingly engaged with the source container. Beverage can be permitted to flow by opening a beverage valve to permit beverage to flow through the beverage pathway under pressure of the interior space of the source container. In some cases, gas can be vented from the destination container via a vent conduit that is sealingly engaged with the destination container. Pressurized gas can be delivered into the interior space of the destination container by in part venting gas from the destination container via a vent conduit that is sealingly engaged with the destination container.
In some embodiments, a beverage container to hold a liquid beverage includes a container body having an interior space to hold the liquid beverage and an opening through which to access the interior space. A cap can be engaged with the container body to seal the opening closed to prevent gas or liquid from passing through the opening, and the cap can include a portion configured to be pierced by a needle to dispense the liquid beverage into the container body and to reseal upon withdrawal of the needle to prevent gas or liquid from passing through the cap. A tamper evident seal can be included with the cap that indicates the cap has not been removed from the container body, e.g., a shrink wrap seal over the cap and/or a breakaway ring or label. The interior space of the container body can contain only gas and no liquid, e.g., the tamper evident seal can indicate that the container contains only inert gas and no liquid and that the container has not been opened to permit air to enter the container.
In some cases, the portion of the container configured to be pierced includes an elastomeric septum configured to be pierced by a needle and to reseal upon withdrawal of the needle, and the elastomeric septum can include a pierced opening that is resealed to prevent gas or liquid from passing through the cap. The pierced opening can be formed by purging the container of air after the cap and tamper evident seal are engaged with the container body. For example, the interior space can contain argon or CO2 gas and include less than 0.5% oxygen gas. In some embodiments, the portion configured to be pierced can include a pierced opening that is resealed to prevent gas or liquid from passing through the cap. In some embodiments, a pressure at the interior space is within 20% of atmospheric pressure, e.g., a pressure above atmospheric pressure.
In some cases, the cap can include a cap body having a passageway from an upper opening to a lower opening of the cap, and a barrier label over the upper opening to resist oxygen entry through the upper opening.
In some embodiments, a beverage container to hold a liquid beverage includes a container body having an interior space to hold the liquid beverage and an opening through which to access the interior space. A cap can be engaged with the container body to seal the opening closed to prevent gas or liquid from passing through the opening with the cap including a portion configured to be pierced by a needle to dispense the liquid beverage into the container body and to reseal upon withdrawal of the needle to prevent gas or liquid from passing through the cap. The interior space can contain only gas and no liquid, and the portion configured to be pierced can include a pierced opening that is resealed to prevent gas or liquid from passing through the cap.
In some embodiments, a method for preparing a beverage container for receipt of a beverage includes providing the beverage container empty of liquid and containing only gas, placing a cap on the beverage container while it is empty of liquid to seal container closed, introducing a non-reactive gas into the beverage container through cap to displace the gas in the beverage container, and sealing the cap to contain the non-reactive inside beverage container with the beverage container empty of liquid. This can prepare the container to receive a beverage sample with minimized risk of exposing the beverage to air.
In some cases, a portion of the cap can be pierced with a needle to introduce the non-reactive gas into the beverage container via the needle. Upon withdrawal of the needle, the portion of the cap can reseal to prevent gas or liquid from passing through the cap. In some cases, an interior space of the beverage container can contain less than 0.5% oxygen gas after the non-reactive gas is introduced into the container. A pressure in the container can be within 20% of atmospheric pressure and can be above atmospheric pressure.
In some embodiments, a barrier label can be provided over an upper opening of the cap to resist oxygen entry through the upper opening, and/or a tamper evident seal can be provided on the cap to indicate the cap has not been removed from the container body. The barrier label and/or tamper evident seal can be provided before the non-reactive gas is introduced into the container.
Various exemplary embodiments of the device are further depicted and described below.
Aspects of the invention are described with reference to various embodiments, and to the figures, which include:
Aspects of the invention are described below with reference to illustrative embodiments, but it should be understood that aspects of the invention are not to be construed narrowly in view of the specific embodiments described. Thus, aspects of the invention are not limited to the embodiments described herein. It should also be understood that various embodiments may be used alone and/or in any suitable combination with each other, and thus various embodiments should not be interpreted as requiring any particular combination or combinations of features. Instead, one or more features of the embodiments described may be combined with any other suitable features of other embodiments.
In some embodiments, beverage such as wine can be transferred from one container to another without exposing the beverage to air or other environmental conditions. Thus, for example, a sample of wine can be transferred from a source bottle or other container to another container (e.g., a smaller sample bottle) for later tasting or other analysis. This can provide various advantages, such as allowing a vendor to store wine in larger containers such as barrels or large bottles and transfer a smaller portion of the stored volume to a smaller container, e.g., at a time of retail sale or assessment by a wholesale purchaser. Since the beverage can be transferred to a sample container without exposure to air or other environmental conditions, the beverage need not be analyzed at the location where it is stored in the larger containers. Instead, the beverage can be taken in a smaller sample container to another remote location for consumption and/or analysis with the assurance that the beverage will be in the same condition as when it was transferred to the sample container.
Regardless of how the first and second transfer heads 1, 2 are engaged and/or fluidly coupled with a respective container 10, 20, the transfer heads 1, 2 can be configured to transfer fluid (gas and/or liquid) with respect to the container 10, 20 (e.g., into and/or out of the container). In
The first transfer head 1 can have first and second gas pathways 4, 5 that are fluidly coupled to the gas inlet of the first transfer head 1 and thus fluidly coupled to the gas source 3 to receive pressurized gas. The first gas pathway 4 can be fluidly coupled to introduce pressurized gas into the interior space of the first container 10, e.g., the first gas pathway 4 can include the second needle 12 and introduce pressurized gas into the first container 10 via the second needle 12. Thus, the first gas pathway 4 can include a first gas outlet (e.g., at the distal end of the second needle 12) to deliver gas to the first container 10. The first gas pathway 4 can include a first gas valve 41 (and/or other components such as a regulator, pressure sensor, etc.) to control gas flow along the pathway 4. The first gas valve 41 can be operable by a user, e.g., manually using a lever or button, to open and close, thereby allowing the user to controllably introduce pressurized gas into the first container 10. In some embodiments, the valve 41 can be controlled by a controller, such as a programmed data processor or other control circuitry. For example, the valve 41 can include an electrically operated solenoid valve that can be controlled to open and close based on suitable electronic signals, e.g., in response to a sensed pressure in the container 10. The controller can adjust a gas pressure and/or flow rate of gas provided to the first container 10 as suitable. Pressurized gas introduced into the first container 10 can raise the pressure inside of the first container 10 to a desired level, e.g., 5 to 50 psi or other pressure suitable to drive flow of beverage from the first container 10, and the pressure can be adjusted during beverage transfer as desired. In some embodiments, the first gas valve 41 can be controlled based on the pressure in the source container 10, e.g., the valve 41 can be turned off automatically when the pressure in the container 10 reaches a particular level. This can help prevent overpressurization of the container 10. The second gas pathway 5 can be fluidly coupled to the second transfer head 2 to introduce pressurized gas into the interior space of the second container 20. For example, the second gas pathway 5 can include a second gas outlet of the first transfer head 1 that is coupled to a gas line which connects to a gas inlet of the second transfer head 2 that is fluidly coupled to the second needle 22 (e.g., which defines a gas outlet of the second transfer head 2).
The second gas pathway 5 can include a second gas valve 51 (and/or other components such as a regulator, pressure sensor, etc.) to control gas flow along the pathway 5. The second gas valve 51 can be operable by a user, e.g., manually using a lever or button and/or by a controller, to open and close, thereby allowing the user to controllably introduce pressurized gas into the second container 20. In some embodiments, pressure in the second container 20 can be vented, e.g., using a vent 24 of the second transfer head 2. The vent 24 can be fluidly coupled to the third needle 23 and thus be capable of venting fluid from the second container 20. In some embodiments, the second gas valve 51 can be selectively opened to introduce pressurized gas into the second container 20 to purge air or other gas from the second container 20. For example, prior to transferring beverage to the second container 20, it may be desirable to purge the container 20 of any air or other potentially contaminating gas. The second gas valve 51 can be opened to deliver pressurized gas into the second container, and as described above, the pressurized gas may be suitably inert, non-reactive or non-damaging to the beverage. As pressurized gas is introduced into the second container, the vent 24 can vent any gas pressure from the container 20, thereby releasing unwanted air or other gas from the container 20. Venting can be achieved by employing any of a variety of pressure-relief valves, either set to vent at a specific pressure or with a variable setting which can be adjusted by the user and/or controlled by a controller, check valves, one way valves, electronically controlled valves, etc. Alternatively, venting could be accomplished using a flow restrictor, again either tunable or set to a fixed flow resistance. Such a restrictor could simply be a small hole or elongated path exiting the transfer head 2. Such a hole or path could employ a semi-permeable membrane that restricts the flow of liquid, but allows the flow of gas. Thus, the vent 24 can include a one-way valve, check valve or other structure suitable to prevent air or other materials from entering the second container 20 through the vent 24. In some cases, the second gas valve 51 can be operated by a timer (e.g., a mechanical or electronically-controlled actuator or controller) so that the valve 51 is opened for a defined period of time so that the second container 20 is purged by pressurized gas during the timer period. Thereafter, the second gas valve 51 can be closed and the second container 20 ready to receive beverage. In some embodiments, a pressure and/or flow rate of gas provided to the second container 20 can be adjusted or otherwise controlled as suitable, e.g., by a controller and associated regulator. For example, in some cases, the container 20 can be pressurized above ambient pressure to receive beverage, e.g., where the beverage is carbonated. The second gas valve 51 can be controlled to maintain a desired pressure in the container 20, e.g., in response to a sensed pressure in the container 20.
A beverage pathway 6 can be provided between the first and second transfer heads 1, 2 so that beverage can be transferred from the first container 10 to the second container 20. Initially, the first or source container 10 can be completely filled or partially filled with beverage, and the second or destination container 20 can be completely empty of any liquid or have some liquid within. In some embodiments, the beverage pathway 6 can include a first beverage pathway of the first transfer head 1 that is fluidly coupled to a second beverage pathway of the second transfer head 2 via a beverage line, e.g., a conduit connected between the transfer heads 1, 2. The beverage pathway can include a beverage valve 61 configured to control delivery of the beverage from the source container 10 to the destination container 20 via the beverage pathway 6. For example, after pressurized gas is delivered to the first container 10 via the first gas pathway 4, the interior space of the first container 10 can be pressurized above ambient pressure and/or above a pressure in the second container 20. The beverage valve 61 can be opened (e.g., manually or automatically by a controller) and beverage can flow through the beverage pathway 6 from the first container 10 to the second container 20. As beverage enters the second container 20 via the first needle 21, pressure in the container 20 can be vented by the vent 24, thereby allowing the second container 20 to the filled with beverage while maintaining a relatively low pressure above ambient in the container 20. In some embodiments, the first needle 21 delivers beverage into the second container 20 at a location that is at or near a bottom or other lowermost part of the interior space of the container 20. For example, the first needle 21 can extend into the container 20 (e.g., the needle 21 can be adjustable in length) so a distal end contacts or is near a bottom of the container 20. As needed, the first container 10 can be repressurized by introducing additional pressurized gas into the first container 10, e.g., by manually or automatically opening the first gas valve 41 when the pressure in the container 10 drops below a particular level, which can be done with the beverage valve 61 open or closed. When the second container 20 is suitably filled with beverage, the beverage valve 61 can be closed and the transfer head 2 disengaged from the second container 20. In some cases, pressurized gas can be introduced into the second container 20 during beverage transfer and/or when beverage transfer is complete, e.g., to maintain carbonation of a sparkling beverage in the container 20 and/or to establish a suitable pressure gradient between the containers 10, 20.

In some embodiments, the first and/or second transfer head 1, 2 can be mounted for movement relative to the support 7 and/or each other. For example,
In some embodiments, the beverage transfer system can include features to automatically engage a source or destination container 10, 20 with a respective transfer head 1, 2. For example,
Although
The embodiment of
Destination containers 20 that contain beverage from a source container 10 can be associated with the source container 10 in various ways, such as by using a computer database and suitable identifiers on the containers 10, 20. For example, source and destination containers 10, 20 can have indicia such as a machine readable code (e.g., optically, magnetically, and/or electromagnetically readable such as the case with barcodes, RFID tags, etc.) that can be read from the containers 10, 20 to obtain a unique identity of the container 10, 20 as well as optionally obtain information about their contents. The identity and association of source and destination containers 10, 20 can be stored in a database, e.g., so that destination containers 20 that hold beverage from a particular source container 10 can be identified and tracked. For example, records can be created for each source container 10 (or each destination container 20) and information regarding associated destination containers 20 (or a source container 10) that contain beverage from the source container 10 stored in a record for the source container 10. Other relevant information can be stored as well, including the beverage type or other characteristics, the date on which and/or location where the beverage transfer was made, the current location or owner of the destination container(s) 20, an identifier of the system used to transfer the beverage from source to destination container, and so on. To form a record, an RFID tag, barcode, a bottle label or other indicia can be read from a source container 10, e.g., to determine a unique identity for the source container 10 and/or other information about the beverage, such as type, vineyard, year bottled, etc. if such information is stored in the machine readable code. If a source container 10 does not have indicia that can uniquely identify the container 10 (e.g., UPC labels generally cannot uniquely identify a particular bottle from other bottles having the same beverage), a label including unique indicia can be applied to the container 10 and then read and used to form a suitable record. As needed, information regarding the beverage in the source container 10 can be obtained by scanning a label or other portion of the source container 10 and accessing a database or other information source. For example, a bottle label can be scanned to identify a vineyard, wine type and year, and information regarding the wine can be retrieved from a database. Indicia on destination containers 20 can also be read, and the unique identifiers for the source container 10 and associated destination containers 20 stored in one or more records along with other information regarding the beverage and/or beverage transfer for later retrieval. This can allow a user of a destination container 20 to easily identify which source container 10 the beverage in the container 20 came from, as well as other information such as the type of beverage or other characteristics, when the sample was taken, and so on.
As noted above, a destination container 20 can be configured in various ways and
The cap 151 can have a lower opening and engage with the container body 26, e.g., by a threaded engagement, adhesive, crimping, friction fit, etc. Thus, the cap 151 can have a passageway through the cap that extends from the upper opening to the lower opening. A tamper evident seal 155 can be provided on the cap to indicate the cap has not been removed from the container body 26. For example, the tamper evident seal 155 can include a shrink wrap covering, sticker, label or other arrangement that allows a user to easily identify whether the cap 151 has been removed from the container body 26. In some cases, the tamper evident seal 155 can include a perforated metal band or sleeve which has a lower part secured to the container body 26 and an upper part that defines the cap 151. When the cap 151 is removed, e.g., by unthreading the cap 151 from the body 26, the perforation can break or separate, indicating the cap has been removed from the body 26. By providing an indication regarding whether the cap 151 has been removed, a user can readily determine whether an interior space of the container 20 has been exposed to air or other environmental conditions whether the container 20 contains beverage or not. For example, the destination container 20 may be sparged or purged of air while the cap is secured to the body 26 and so contain only inert or non-reactive gas and no liquid. Thus, the tamper evident seal 155 can indicate that the sparged or purged container 20 remains unopened and ready to receive beverage. Alternately, the container 20 can be at least partially filled with beverage while the cap 151 is secured to the body 26. In this case, the tamper evident seal 155 can indicate whether the beverage has been exposed to air or other environmental conditions by removal of the cap 151. The tamper evident seal 155 can extend over the upper opening 156, e.g., define the barrier label 154 or extend over the barrier label 154 if desired.
To make beverage transfer more convenient for a user, the user can be provided with a destination container 20 that has a pre-sealed interior space, e.g., having a container body 26 and cap 151 that seals the interior space of the body 26, and the pre-sealed interior space can be sparged or purged of air and other materials. Having the interior space sparged before use can make beverage transfer easier, e.g., because a user need not sparge the container 20 prior to transfer and/or because the container 20 can be ensured to be sparged to have particular conditions that a user may not easily be able to replicate. For example, a container 20 can be sparged so the interior space contains only gas and no liquid, contains argon or CO2 gas, includes less than 0.5% oxygen gas, and/or has an internal pressure within 20% of atmospheric pressure (e.g., that is above atmospheric pressure to help prevent entry of ambient air or other exterior environment into the interior space). Since sparging can occur after a cap 151 or other closure 15 is secured to the container body 26, a septum or other piercable element of the closure 15 may have pierced opening that is resealed to prevent gas or liquid from passing through the cap as a result of the sparging operation. Alternately, the containers 20 need not be pre-sparged and may be sparged or purged by a user, e.g., immediately before transferring beverage to the container 20. After sparging or transfer of beverage, a barrier label 154 can be placed on the cap 151 or other closure 15 to help provide a barrier to entry of oxygen or other materials, e.g., through the septum or a resealed opening in the septum.
In some embodiments, the container body 26 can be a rigid structure that defines the interior space of the container body 26 to have a particular fixed volume. For example, the container body 26 can be made of a glass, metal, rigid plastic or other material. In some embodiments, the container body 26 can be collapsible, expandable or otherwise define a variable volume for the internal space. As an example, the container body 26 can be made of a flexible film or other material to form a pouch or other container that has a variable internal volume. In some cases, a container 20 having a collapsible and/or expandable container body 26 can be arranged to have a minimum internal volume before beverage is transferred to the container 20. This can avoid or reduce any need to purge the internal volume of the container 20 prior to transferring beverage to the container 20. Alternately, such a container 20 can be purged (e.g., using an inert or other suitable gas), but the reduced or minimized internal volume of the container 20 during purging can reduce an amount of gas needed for purging. A container 20 having a collapsible or expandable container body 26 can have any suitable type of closure 15, such as those described above. Transfer of beverage to the container 20 can cause the container body 26 to expand so as to increase the internal volume of the container 20 to accommodate the beverage.
Regarding needles that may be used in various embodiments to access the interior space of a container, it has been found that needles having a smooth walled exterior, non-coring pencil point (having an opening at the needle sidewall) or Huber point needle of 15 gauge or higher are effective to penetrate through a wine bottle cork, septum or other closure, while sealing effectively with the cork to prevent the ingress or egress of gases or fluids during beverage transfer and/or after needle removal. Moreover, such needles allow the cork to reseal after withdrawal of the needle, allowing the bottle and any remaining beverage to be stored for months or years without abnormal alteration of the beverage flavor. Further, such needles may be used to penetrate a foil cover or other wrapping commonly found on wine bottles and other bottles. Thus, the needle may penetrate the foil cover or other element as well as the closure, eliminating any need to remove the foil or other wrapping prior to beverage extraction. Other needle profiles and gauges are also usable with the system. A needle can have a non-coring tip that can be passed through a cork or other closure without removing material from the cork. One non-coring tip is a pencil-tip that dilates a passageway through the cork, although deflected-tip and stylet needles have also been found to work properly and could be used. The pencil-tip needle preferably has at least one lumen extending along its length from at least one inlet on the end opposite the pencil-tip and at least one outlet proximal to the pencil-tip. A needle outlet may be positioned in the side-wall of the needle at the distal end of the needle, although proximal of the extreme needle tip. Multiple relatively small holes may be provided in the needle sidewall.
With the correct needle gauge, it has been found that a passageway (if any) that remains following removal of the needle from a cork, septum or other closure self-seals against egress or ingress of fluids and/or gasses under normal storage conditions. Thus, a needle may be inserted through a closure to extract beverage, and then be removed, allowing the closure to reseal such that beverage and gas passage through the closure is prevented. While multiple needle gauges can work, preferred needle gauges range from 16 to 22 gauge, with an optimal needle gauge in some embodiments being between 16 and 20 gauge. These needles gauges may offer optimal fluid flow with minimal pressures inside the bottle while doing an acceptably low level of damage to the cork even after repeated insertions and extractions.
Multiple needle lengths can be adapted to work properly in various embodiments, but it has been found that a minimum needle length of about 1.5 inches (3.8 cm) may be required to pass through standard wine bottle corks. Needles as long as 9 inches or more could be employed, e.g., to extend from an opening of a bottle to the bottom of the bottle. When two or more needles are used, the needle lengths may be the same or different and vary from 0.25 inches to 10 inches (0.64 to 25.4 cm). Creating distance between the inlet/outlets of the needles can prevent cross contamination/flow between the two lumens.
In some embodiments, the length, gauge, opening size and/or other characteristics of a needle can be adjusted to optimize gas and beverage flow without causing froth or foaming of a beverage. Huber point and similar needles have been found to be particularly effective in this regard. In some cases, needles are optimized so as to reduce their length and provide a fastest fluid flow without causing froth or foaming of a beverage such as wine. Needles can be used to penetrate a septum or other closure in different ways, e.g., so that the needle passes through the septum or other closure in a direction perpendicular to an entry plane of the closure, in a direction at a non-perpendicular angle to the entry plane of the closure, and in other ways. In some embodiments, needles having a curved shape can be employed and penetrated through a cork, septum or other closure. Such a curved needle can be penetrated through a closure by pivoting the needle about an axis so that the leading end of the needle penetrates the closure in a direction that is perpendicular to the entry plane of the closure but the needle follows a curved path through the closure. In some embodiments, a curved needle can penetrate a closure so that a distal end or other portion of the needle that has an outlet opening is located adjacent an inner wall of the container. This can allow beverage such as wine to flow into the container and contact the inner wall of the container at a relatively high flow rate without creating froth or foam or otherwise minimizing mixing of the beverage with gas in the container.
In some embodiments, a suitable gas pressure is introduced into a source container to extract beverage. For example, it has been found that a maximum pressure of between around 20 and 100 psi (1.4-6.9 bar) may be introduced into the bottle without risking leakage at, or ejection of, the cork, although other pressures may be used. In some embodiments, the system can include a pressure meter that detects the original pressure within the source container. The pressure meter can act as a guide to the user as to the appropriate pressure to introduce into the source container. Alternatively, an electronic control system can be employed to automatically dispense beverage and pressurize the source container to a suitable pressure for transfer. Any version of a pressure monitoring or control system, either by the user or electronically, could also be used.
The source of pressurized gas can be any of a variety of regulated or unregulated pressurized gas bottles filled with any of a variety of non-reactive gasses. In a preferred embodiment, the gas cylinder contains gas at an initial pressure of about 2000-3000 psi (138-207 bar). This pressure has been found to allow the use of a single relatively small compressed gas cylinder (e.g., about 3 inches [7.6 cm] in length and 0.75 inches [1.9 cm] in diameter) for the transfer of the contents of several bottles of wine. Multiple gasses have been tested successfully over extended storage periods. Preferably the gas used is non-reactive with the beverage within the bottle, such as wine, and can serve to protect the beverage from oxidation or other damage, but any suitable gas that is reactive or non-reactive with beverage can be used. Suitable gases include nitrogen, carbon dioxide, argon, helium, neon and others. Mixtures of gas are also possible. For example, a mixture of argon and another lighter gas could blanket wine or other beverage in argon while the lighter gas could occupy volume within the bottle and perhaps reduce the overall cost of the gas. Pure carbon dioxide has been found as a preferred gas for most sparkling wine beverages.
