Definitions

  • the present invention relates generally to the field of apparatus to prolong the life of drinks particularly wine once opened.
  • a wine fault or defect is an unpleasant characteristic of a wine often resulting. from poor winemaking practices or storage conditions, and leading to wine spoilage.
  • Many of the compounds that cause wine faults are already naturally present in wine but at insufficient concentrations to adversely affect it. In. fact, depending on perception, these concentrations may impart positive characters to the wine. However when the concentration of these compounds greatly exceeds the sensory threshold, they replace or obscure the flavors and aromas that the wine should be expressing. Ultimately the quality of the wine is reduced, making it less appealing and sometimes undrinkable.
  • the oxidation of wine is perhaps the most common of wine faults, as the presence of oxygen and a catalyst are the only requirements for the process to occur. It is also known as maderized wine, from Madeira wine, which is intentionally oxidized. Oxidation can occur throughout the winemaking process, but more typically occurs after the wine has been opened and a portion remains in the bottle.
  • a variety of mechanisms and devices have been developed in the past in order to overcome or at least ameliorate oxidation of wine in a partially opened wine bottle. These include closures which allow the venting of gases from an open bottle which has been resealed, the application of a vacuum technology to partially withdraw any gases from an upper portion of the bottle.
  • the present invention is directed to a resealable decanter, which may at least partially overcome at least one of the abovementioned disadvantages or provide the consumer with a useful or commercial choice.
  • the present invention in one form, resides broadly in a resealable decanter associated with a gas evacuation system, the decanter having a body with an upper opening adapted to be closed with a removable sealing closure and a movable wall located within the body, the movable wall moveable at least upwardly within the body to move liquid within the decanter body toward the upper opening thus evacuating gas from the decanter body in the procesSi
  • the present invention resides broadly in a resealable decanter with evacuation system, the decanter having a body with an upper opening adapted to be closed with a removable sealing closure and a lower opening adapted to be sealed by a movable wall, the evacuation system including a closure to close the opening of the decanter and an actuable expansion unit located within the decanter body in association with the movable wall to expand and move the wall as required to move the liquid within the decanter body to the upper opening .thus evacuating gas from the decanter body in the process.
  • the present invention resides broadly in a resealable decanter with evacuation system, the decanter having a body with an upper opening adapted to be closed with a removable sealing closure and a lower opening adapted to be sealed, the evacuation system including a closure to close the opening of the decanter and an actuable expansion unit located within the decanter body to expand as required to displace the liquid within the decanter body to the upper opening thus evacuating gas from the decanter body in the process.

  • the expansion unit is preferably mounted in association with a closure for closing or opening of the base of the decanter body and is normally mounted relative to the closure for movement.
  • the expansion unit may expand in any direction, all directions, or one direction only with a portion of any expansion being upwards .
  • a seal will be maintained with the inside surface of the decanter body in order to force the liquid ahead of the movable wall.
  • the evacuation system is typically provided in association with the movable wall and is actuable from outside the decanter body.
  • the evactuation system may be separate from the decanter but adapted to be used removeably with the decanter in order to move the moveable wall within the decanter to change (either increase or decrease) the storage volume within the decanter.
  • the movable wall will preferably extend across the lower end of the decanter and upon actuation, move upwardly.
  • the movable wall may be resilient or at least an edge portion of the movable wall will be resilient in order to create and maintain a seal with the inner surface of the body of the decanter. Therefore, a seal may be provided integrally with the movable wall or separately therefrom.

  • sealing means will normally be provided in order to seal the upper portion to the main body portion. .
  • the upper end of the upper portion will be formed with an opening and an appropriate sealing mechanism in order to seal the decanter.
  • a cap/valve assembly will be utilised at the upper opening.
  • the sealing mechanism is preferably such that a vacuum pump can be used in conjunction with the opening and/or sealing mechanism to evacuate gas from the decanter body, normally by moving the moveable wall upwardly toward the sealing mechanism to decrease the volume of storage.
  • the vacuum pump may withdraw or evacuate gas about the cap or closure of the decanter whilst the cap or closure is in place.
  • the vacuum pump may be used to evacuate gas from the decanter without the cap or closure. Operation of the vacuum pump preferably draws the movable wall towards the neck until the liquid is approximately at the level of the opening in the neck at which time the cap or closure can be placed onto the neck sealing the decanter.
  • the movable wall and/or interior surface of the main body portion is provided with an alignment means which maintains the movable wall in sealing engagement with the inner surface of the main body portion.
  • the movable wall will move ' upwardly and downwardly without tilting as this may cause a loss of seal between the movable wall and the main body portion which may allow the liquid to seep or flow, between the movable wall and the main body portion. It is preferred that the liquid at all times remain above the movable wall and that the movable wall remains sealed to the interior surface of the main body portion. Therefore, movement of the movable wall will in turn move the level of the liquid.
  • the moveable wall may be provided with an upwardly extending portion in order to minimise the head space in the upper portion of the decanter particularly when the moveable wall is located adjacent or above the top of the body. Due to the shape of the upper portion, without providing an upwardly extending portion to minimise the head space in the decanter, the decanter would be less useful as there would be a volume which cannot be decreased once the moveable wall reaches a converging portion of the decanter.
  • the upper portion of the decanter will normally be provided with depressed sections in order to minimise the head space in the upper portion.
  • a valve assembly is preferably provided in association with the closure of the decanter.
  • the cap and valve assembly are provided as separate but engageable components.
  • the valve assembly will preferably limit or prevent liquid escaping or being lost from the decanter into or through the preferred vacuum purrip but will allow gas to be drawn from the decanter by the preferred vacuum pump.
  • the valve assembly may be permanently positioned in the upper portion of the decanter or alternatively, may be removeably engageable with the upper portion.
  • the valve assembly will preferably be provided as a sleeve portion adapted to be received at least partially within the neck of the upper portion of the decanter.
  • the sleeve portion will normally be securable within the neck portion and typically, a thread arrangement is provided on an internal surface of the neck portion and an external portion of the sleeve.
  • a valve will normally be provided at a lower part of the sleeve portion, normally to be located centrally across the opening of the decanter.
  • the valve will preferably be a non-return type valve and a captured ball valve is particularly preferred.
  • a ball valve member is located in a valve surround and at least a pair of openings are provided in the surround, one on the decanter side of the surround and one associated with the opening of the decanter. More openings may be provided such as for example, through one or more of the sidewalls of the surround. The openings may be any shape.
  • the ball valve member will preferably move within the surround in order to allow gas to be evacuated from the decanter upon application of a vacuum inducing pump but will preferably prevent loss of liquid from the decanter.
  • the ball valve member will typically move to allow gas to exit the decanter through the openings in the surround, flow around the ball valve member and exit through the upper opening.
  • the ball valve member will preferably be buoyant relative to the liquid but be weighted to limit or prevent the ball valve member the sealing the upper opening in the surround under the action of the vacuum pump.
  • the ball valve member may have a guide portion associated therewith to limit or control movement of the ball valve member.
  • a guide portion may be provided as an extension from the ball valve member adapted to engage part of the surround in order to limit the movement of the ball valve to a reciprocal movement towards and away from the decanter opening.
  • a limit means may be provided with the guide means to limit the degree of movement allowed.
  • an enlarged head may be provided to suspend the ball valve member relative to the opening but allow movement towards and away from the opening until moved to the closed condition by the liquid level.
  • the ball valve member can move within the surround but movement is limited.
  • a keylock mechanism is preferably provided between the cap and the valve sleeve.
  • a pair of corresponding portions are provided, one on the cap and one on the preferred valve sleeve to allow the cap and a valve sleeve to engage one another. This will typically allow rotation of the cap and due. to the engagement between the cap and the valve sleeve, the valve sleeve can be rotated. This configuration is particularly useful to remove the valve sleeve which is preferably engaged with the upper portion of the decanter by a threaded portion.
  • the corresponding portions will take the form of a key and slot.
  • at least one, and normally a pair of opposed slots are provided on the cap, and at least one and normally a pair of opposed corresponding key protrusions are provided on an internal portion of the valve sleeve such that when the cap is insertedtivo the valve sleeve, the cap may be rotated until the keys are aligned with the slots whereupon the cap can be pushed further downwardly into the valve sleeve. In this position, rotation of the cap will typically rotate the valve sleeve. Pulling the cap away from the valve sleeve will typically disengage the corresponding portions allowing removal of the cap without disengagement of the valve sleeve.
  • the expansion unit may be a bellows or concertina type expansion unit.
  • Alternative mechanisms for moving the movable wall may include pneumatic, manual, sliding, biased or the like.
  • the two main types will be an air expansion bellows or a manual, sliding expansion mechanism. According to the bellows configuration, air or another gas may be forced into the expansion unit to expand the expansion unit, to move the movable wall upwards.
  • a flexible but fixed length rod may be provided extending substantially parallel to an outer portion of the decanter before an arcuate portion which extends under the decanter bottom and upwardly towards the movable wall. Depression of the rod downwardly parallel to the decanter will typically force the movable wall upwards. Guides will typically be provided to guide any movement, including roller guides in order to guide the arcuate movement.
  • any method of displacement may be used.
  • a bladder or similar will be provided within the decanter body and changes in volume of eth bladder will displace the fluid in the decanter body.
  • the bladder may expand in any direction, all directions, or one direction only.
  • the bladder may therefore be a concertina type bladder which expands upwardly or a flexible bladder that expands in three dimensions within the decanter body to displace the fluid within the decanter body upwards towards the upper opening of the decanter.
  • a sleeve is provided about the decanter in order to cover any moving parts.
  • This sleeve will have a base which also protects the lower portion of the mechanism.
  • an aesthetically pleasing material is used for the sleeve such as stainless steel or similar.
  • This sleeve may be spaced from the body of the decanter in order to allow material to be located within the space to adjust .the temperature of the beverage or alternatively, this sleeve may closely receive the body of the decanter.
  • the sleeve will be opaque and obscure a lower portion of the decanter leaving the upper portion of the decanter visible.
  • all or part of the decanter may be transparent, this will allow a user to observe the rising beverage level as the movable wall extends upwardly until the valve at the upper opening of the decanter is activated. In the absence of a valve the user will need to observe the rising beverage level in order that the beverage not overflow.
  • Weighting may be provided at a lower level on the decanter in order to provide stability to the decanter, particularly when the liquid contained therein is towards the upper end of the decanter.
  • the weighting may be provided in association with the base.
  • a beverage which is the subject to deterioration by oxidation may be decanted into the decanter body whereupon the movable wall can be actuated to move the upper level of the liquid to be closely spaced from the upper opening of the decanter, preferably by means of a vacuum pump associated with the decanter opening to evacuate the gas from the decanter, in order to minimise any gas remaining in the decanter body after which the sealing closure can be placed over the upper opening.
  • a minimum amount of oxygen or other gas is maintained above the liquid which in turn will minimise the degree of oxidation of the liquid, thus maintaining quality of the liquid.

  • a ball valve member 51 is located in a valve surround 52 and a pair of openings are provided in the surround, one on the decanter side of the surround and one associated with the opening of the decanter.
  • the opening 54 in the surround 52 associated with the opening of the decanter is positioned such that the ball valve member can seal the opening when the liquid in the decanter raises the ball valve member as the liquid level moves towards the decanter opening.
  • the ball valve member 51 can move within the surround 52 in order to allow gas to be evacuated from the decanter upon application of a vacuum inducing pump (not shown) but will preferably prevent loss of liquid from the decanter.
  • the ball valve member 51 moves to allow gas to exit the decanter through the decanter side opening 53, flow around the ball valve member 51 and exit through the upper opening 54.
  • the movable wall 43 moves upwardly and the level of liquid in the decanter rises toward the valve assembly, and the liquid level lifts the ball valve member 51 to close the upper opening in the surround 52, thereby preventihg liquid being drawn out of the decanter by the vacuum pump. Therefore, the ball valve member is preferably buoyant relative to the liquid but be weighted to limit or prevent the ball valve member the sealing the upper opening in the surround under the action of the vacuum pump.
  • the gas evacuation system will typically include an external vacuum pump (not illustrated) which is engageable with the decanter to evacuate gas as required.
  • the vacuum pump is used to evacuate gas from the decanter before the cap 13 has been used to seal the opening. Operation of the vacuum pump preferably draws the movable wall 15 towards the upper opening until the liquid is approximately at the level of the opening in the neck at which time the cap 13 can be placed onto the neck sealing the decanter.
  • a vacuum pump is used to move the moveable wall 43 upward until the liquid level actuates the valve assembly to prevent fluid escaping from the decanter.
  • a keylock mechanism is provided between the cap 46 and the valve sleeve 47. Corresponding portions are provided, one on the cap and one on the preferred valve sleeve to allow the cap and a valve sleeve to engage one another.
  • a pair of opposed slots 60 are provided on the cap 46, and a pair of opposed corresponding keys 61 are provided on an internal portion of the valve sleeve 47 such that when the cap 43 is inserted into the valve sleeve 47, the cap 43 cane rotated until the keys 61 are aligned with the slots 60 whereupon the cap 43 can be pushed further downwardly into the valve sleeve 47. In this position, rotation of the cap 43 rotates the valve sleeve 47. Pulling the cap 43 away from the valve sleeve 47 disengages the corresponding portions allowing removal of the cap 43without disengagement of the valve sleeve 47.
  • FIG. 7 is an exploded view of a further preferred embodiment of the decanter of eth present invention.
  • the decanter illustrated in Figure 7 has all of the components of the embodiment illustrated in Figure 5, namely:
  • the embodiment illustrated in Figure 7 also includes a preferred stainless steel sleeve 65 for the body of the decanter and a second, smaller stainless steel sleeve 66 for the upper portion of the decanter. These are provided for aesthetics and to obscure the working components (moveable wall 43 and valve sleeve 47) from view.
  • Figure 7 also illustrated two branding opportunities for the application of labels 67 to the exterior of the decanter.
  • the movable wall moves upwardly and downwardly without tilting as this may cause a loss of seal between the movable wall and the main body portio which may allow the liquid to seep or flow between the movable wall and the main body portion. It is preferred that the liquid at all times remain above the movable wall and that the movable wall remains sealed to the interior surface of the main body portion. Therefore, movement of the movable wall will in turn move the level of the liquid.
