Beverage bottle and method for maintaining carbonation

Abstract

A bottle and method is provided for storing a carbonated beverage so that the beverage can be dispensed over time without the beverage remaining in the container losing carbonation. The bottle can be comprised of a container having a bladder inserted therein. The annular space between the container and the bladder is accessed through a pressure port by a pump and the container is pressurized such that the bladder is compressed and the useable volume of the bottle is reduced. By reducing the volume, excess air can be prevented from collecting in the bottle.

1 . A bottle for storing a liquid, comprising: 
 a container adapted to be pressurized, the container having: 
 a bladder adapted to contain the liquid; and  
 a pressure port for pressurizing the container such that the bladder is compressed; and  
   a dispensing port of the container.    
     
     
         2 . The bottle for storing a liquid of  claim 1 , wherein the container is one of cylindrical, contoured and stylized in shape.  
     
     
         3 . The bottle for storing a liquid of  claim 1 , including a charging port for providing the liquid to the bladder.  
     
     
         4 . The bottle for storing a liquid of  claim 1 , including a pump selectably insertable into the pressure port for pressurizing the container.  
     
     
         5 . The bottle for storing a liquid of  claim 5 , wherein the pump is adapted to provide ambient air to the container for pressurizing the container.  
     
     
         6 . The bottle for storing a liquid of  claim 1 , including a relief valve for depressurizing the container.  
     
     
         7 . The bottle for storing a liquid of  claim 1 , including a siphon having a distal end adapted to be inserted into the bladder such that a proximal end of the siphon extends outside the container, which siphon providing a conduit for the liquid.  
     
     
         8 . The bottle for storing a liquid of  claim 7 , wherein the siphon includes a valve adapted to regulate a flow of liquid through the siphon.  
     
     
         9 . The bottle for storing a liquid of  claim 8 , wherein the distal end of the siphon is beveled.  
     
     
         10 . A bottle for storing a liquid, comprising: 
 a container adapted to be pressurized;    a bladder connected with the container and adapted for containing the liquid;    a pressure port for pressurizing the container such that the bladder is compressed; and    a dispensing port for dispensing the liquid.    
     
     
         11 . The bottle for storing a liquid of  claim 10 , including a sealable charging port for providing the liquid to the bladder.  
     
     
         12 . The bottle for storing a liquid of  claim 10 , including a pump selectably insertable into the pressure port for pressurizing the container.  
     
     
         13 . The bottle for storing a liquid of  claim 10 , including a pump connected with the pressure port for pressurizing the container, wherein the pump is adapted to be manually operated to provide ambient air to the container.  
     
     
         14 . The bottle for storing a liquid of  claim 10 , including a siphon having a distal end adapted to be inserted into the bladder such that a proximal end of the siphon extends outside the dispensing port, which siphon providing a conduit for the liquid.  
     
     
         15 . The bottle for storing a liquid of  claim 14 , wherein the siphon includes a valve adapted to regulate a flow of liquid through the siphon.  
     
     
         16 . The bottle for storing a liquid of  claim 15 , wherein the distal end of the siphon is beveled.  
     
     
         17 . The bottle for storing a liquid of  claim 10 , including a relief valve for depressurizing the container.  
     
     
         18 . A method for storing a liquid in a bottle having a container connected with a bladder for containing the liquid, the container having a pressure port for pressurizing the container such that the bladder is compressed, comprising: 
 connecting a pump with the pressure port;    pressurizing the container with the pump such that excess air is forced out of the bladder;    sealing the bottle such that no excess air enters the bladder; and    disconnecting the pump from the pressure port.    
     
     
         19 . The method for storing a liquid of  claim 17 , further comprising: 
 depressurizing the container using a relief valve connected with the container;    unsealing the bottle;    filling the bladder with a liquid through a charge port; and    resealing the bottle.    
     
     
         20 . The method for storing a liquid of  claim 17 , further comprising: 
 inserting a distal end of a siphon into the bladder such that the proximal end of the siphon extends outside the bladder, wherein the siphon includes a valve preventing excess air from entering the bladder once the bottle is sealed.
