Resealable decanter with evacuation system

Abstract

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 process.

1 . 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 through application of a vacuum thereto to move liquid within the body toward but not out of the upper opening whereby the liquid contents are removable from the decanter by pouring from the decanter. 
     
     
         2 . A resealable decanter associated with a gas evacuation system as claimed in  claim 1  further including a valve assembly located adjacent the upper opening allowing a vacuum to be applied to the decanter to evacuate gas from the decanter body and to prevent loss of liquid from the decanter whilst the vacuum is applied. 
     
     
         3 . A resealable decanter associated with a gas evacuation system as claimed in  claim 1  wherein the decanter includes at least a substantially hollow body and a removable upper portion having a shoulder dimensioned to attach to the body and a relatively smaller upper opening for pouring liquid from the decanter. 
     
     
         4 . A resealable decanter associated with a gas evacuation system as claimed in  claim 3  wherein at least one sealing member is provided between the hollow body and upper portion to form a storage volume when the decanter is assembled. 
     
     
         5 . A resealable decanter associated with a gas evacuation system as claimed in  claim 1  wherein the movable wall is provided inside the body forming a base of the storage volume in the decanter into which a liquid is placed. 
     
     
         6 . A resealable decanter associated with a gas evacuation system as claimed in  claim 1  wherein a vented base is attachable to the body to prevent a vacuum occurring below the moveable wall. 
     
     
         7 . A resealable decanter associated with a gas evacuation system as claimed in  claim 1  wherein the movable wall and an inner surface of the body are provided with an alignment means which maintains the movable wall in sealing engagement with the inner surface of the body during movement. 
     
     
         8 . A resealable decanter associated with a gas evacuation system as claimed in  claim 1  wherein the moveable wall is provided with an upwardly extending portion in order to minimise the head space in an upper portion of the decanter. 
     
     
         9 . A resealable decanter associated with a gas evacuation system as claimed in  claim 1  wherein the sealing closure includes a cap and valve assembly provided as separate but engageable with each other and the upper opening of the decanter. 
     
     
         10 . A resealable decanter associated with a gas evacuation system as claimed in  claim 9  wherein corresponding portions are provided on the cap and the valve assembly to allow engagement of the cap and valve assembly for movement together and disengagement for movement relative to one another wherein engagement permits removal of the valve assembly and cap for pouring of liquid contents via the upper opening and disengagement permits removal of the cap alone for application of a vacuum to the valve assembly. 
     
     
         11 . A resealable decanter associated with a gas evacuation system as claimed in  claim 9  wherein the valve assembly includes a sleeve portion adapted to be received at least partially into the upper opening of the decanter and be securable therein. 
     
     
         12 . A resealable decanter associated with a gas evacuation system as claimed in  claim 10  wherein the valve operates to allow gas to evacuate from the decanter but preventing liquid flow through the valve. 
     
     
         13 . A resealable decanter associated with a gas evacuation system as claimed in  claim 12  wherein the valve functions as a float valve to prevent liquid flow. 
     
     
         14 . A resealable decanter associated with a gas evacuation system as claimed in  claim 12  wherein a valve member functions to prevent liquid flow but allow gas flow and not seal under the imposition of a vacuum. 
     
     
         15 . 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 upper 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 in the process. 
     
     
         16 . 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 upper 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 in the process. 
     
     
         17 . A resealable decanter as claimed in  claim 15  wherein the actuable expansion unit is manually actuated. 
     
     
         18 . A resealable decanter as claimed in  claim 15  wherein an air expansion unit is used. 
     
     
         19 . A resealable decanter as claimed in  claim 15  wherein actuable expansion unit is expanded by application of a vacuum at the upper opening of the decanter.
