Beverage dispensing system, beverage container and pressurizing system for use in a beverage dispensing system or container

A method for regulating pressure in a beverage dispensing system, said beverage dispensing system comprising a beverage container with a beverage compartment and a pressurizing system, wherein the pressurizing system comprises a gas container comprising a pressurized gas, a closure closing the gas container and a pressure regulator operative for opening the closure for allowing gas to enter from the gas container into the beverage compartment, wherein the pressure regulator comprises a regulating chamber having at least a wall part movable and/or deformable based on pressure in the beverage compartment, wherein at least one opening is provided through a wall of the regulating chamber providing for at least part of a gas passage between the regulating chamber and the beverage compartment, wherein the beverage compartment is filled at least partly with a carbonated beverage, wherein over an extended period of time, when no beverage is dispensed, temperature changes of the beverage leading to a change of pressure in the beverage compartment is followed by the same pressure change inside the regulating chamber by feeding gas into the regulating chamber from the beverage compartment or feeding gas from the regulating chamber into the beverage compartment, though said at least one opening, wherein the gas introduced from the beverage compartment into the regulating chamber or from the regulating chamber into the beverage compartment is fed through a labyrinth having an end in fluid communication with the beverage compartment and an opposite end in fluid communication with the at least one opening.
