Container for pressurized liquids

Abstract

A disposable container for a pressurized fluid, comprises a fluid resistant bag, and a reinforcing network applied about the bag. A rigid drum structure preferably surrounds the bag. The container is useful for storing fluids to a pressure of around 6 bar and provides a disposable container for transporting beer.

What is claimed is:  
     
         1 . A container for a pressurized fluid, comprising a fluid resistant bag, and a reinforcing network applied about said bag.  
     
     
         2 . The container of  claim 1 , wherein said bag is a flexible bag.  
     
     
         3 . The container of  claim 1 , further comprising a rigid cylindrical body located externally of said bag and of said reinforcing network.  
     
     
         4 . The container of  claim 1 , further comprising a nozzle for pressure sealing said bag.  
     
     
         5 . The container of  claim 3 , wherein said fluid resistant bag, said reinforcing network and said rigid cylindrical body are configured together to withstand up to  6  bar of fluid pressure from within said bag.  
     
     
         6 . The container of  claim 3 , wherein there is a gap between said bag and said rigid cylindrical body, the container comprising a nozzle for pressure sealing said bag and an inserter for inserting fluid into said gap to pump fluid out of said bag.  
     
     
         7 . The container of  claim 1 , wherein said pressurized fluid is a carbonated drink.  
     
     
         8 . The container of  claim 1 , wherein said pressurized fluid is beer.  
     
     
         9 . The container of  claim 1 , comprising plastics material.  
     
     
         10 . The container of  claim 3 , wherein each of said bag, said network body and said rigid body separately comprise a plastics material.  
     
     
         11 . The container of  claim 3 , wherein each of said rigid body and said network body comprise plastics material and said bag comprises a metallic foil.  
     
     
         12 . The container of  claim 3 , wherein said bag comprises at least two bag layers.  
     
     
         13 . The container of  claim 12 , wherein said network body is located between said at least two bag layers.
