Method and a system for pressurising and dispensing carbonated beverages

A method for producing a self-regulating and constant pressure maintaining beverage dispenser assembly, comprising:

• providing a flexible and compressible beverage container having an opening and defining an inner space for filling and accommodating a carbonated beverage, said inner space and said beverage container being variable between a compressed state and an uncompressed state, wherein, when filled with carbonated beverage, said inner space defines a beverage space and a head space;
• providing a dispensing device communicating with said beverage space;
• providing at least one carbonisation canister comprising a particular amount of adsorption material, said adsorption material being capable of adsorbing a specific amount of CO2, said specific amount of CO2 being sufficient for during beverage dispensing at a specific temperature of 2° C.-50° C. and an initial pressure of 0.1-3 bar above the atmospheric pressure allowing said head space to substitute said beverage space while maintaining at least a pressure of 0.1-3 bar above the atmospheric pressure in said head space, said adsorption material being separated from the outside of said canister by a hydrophobic labyrinth, said hydrophobic labyrinth being initially sealed by a burst membrane having a specific burst pressure;
• introducing said carbonisation canister into said beverage container;
• introducing carbonated beverage through said opening into said inner space thereby establishing said beverage space and said head space, said beverage space communicating with said head space and said head space communicating with said carbonisation canister;
• causing said beverage container and said inner space to assume said compressed state and substantially eliminating said head space;
• and
• introducing a pre-determined amount of CO2 at a specific pressure profile into said inner space while causing said beverage container to assume said uncompressed state for re-establishing said head space having said initial pressure and communicating with said carbonisation canister and said beverage space while said specific pressure profile at least at some instance exceeding said bursting pressure of said burst membrane for causing said burst membrane to rupture and said adsorption material in said canister to adsorb said specific amount of CO2.
