Method of dispensing carbonated beverage, a beverage dispensing system and a collapsible container

A collapsible beverage container for use together with a beverage dispensing system, said beverage dispensing system comprising a pressure chamber for accommodating said collapsible beverage container, said pressure chamber being capable of maintaining a first elevated pressure within said pressure chamber, said collapsible beverage container being made of a flexible material and including a beverage space containing carbonated beverage and a head space containing gas, said first elevated pressure acting on said collapsible beverage container for crumpling said collapsible beverage container at a container crumpling pressure and establishing a second elevated pressure within said collapsible beverage container, said first elevated pressure being equal to the sum of said second elevated pressure and said container crumpling pressure, said collapsible beverage container including an interruption valve defining an open position and a closed position, said open position allowing carbonated beverage to flow out from beverage space when said pressure chamber is pressurized, said closed position preventing carbonated beverage from flowing out from said beverage space, said interruption valve assuming said open position when said second elevated pressure exceeds a specific non-zero pressure reference, said interruption valve assuming said closed position when said second elevated pressure falls below said specific non-zero pressure reference.

A beverage dispensing system comprising:

• a pressure chamber accommodating a collapsible beverage container made of a flexible material, said collapsible beverage container including a beverage space containing carbonated beverage and a head space containing gas, said pressure chamber being capable of maintaining a first elevated pressure within said pressure chamber, said first elevated pressure acting on said collapsible beverage container for crumpling said collapsible beverage container at a container crumpling pressure and establishing a second elevated pressure within said collapsible beverage container, said first elevated pressure being equal to the sum of said second elevated pressure and said container crumpling pressure;
• a dispensing device including a tapping valve and defining a beverage dispensing position and a non-beverage dispensing position;
• and
• a tapping line interconnecting said collapsible beverage container within said pressure chamber and said dispensing device, said tapping line including an interruption valve defining an open position and a closed position, said open position allowing carbonated beverage to flow from said beverage space to said dispensing device when said pressure chamber is pressurized, said closed position preventing carbonated beverage from flowing from said beverage space to said dispensing device, said interruption valve assuming said open position when said second elevated pressure exceeds a specific non-zero pressure reference, said interruption valve assuming said closed position when said second elevated pressure falls below said specific non-zero pressure reference.
