A self regulating and constant pressure maintaining product dispenser assembly comprises a dispensing device and a product container defining an inner space comprising a product space being filled with a fluid product constituting a carbonated beverage, and a pressure space being filled with a propellant gas having an initial pressure of preferably 0.5-1.8 bar above the atmospheric pressure when subjected to a specific temperature range of preferably 3° C.-50° C. The pressure space further comprises an amount of an adsorption material having adsorbed an amount of the propellant gas, which is sufficient for allowing the pressure space to increase in volume and to substitute the product space. The particular amount of adsorption material is inherently capable of substantially maintaining the initial pressure in the pressure space by releasing the propellant gas into the pressure space and adsorbing the propellant gas from the pressure space.

1. A method for storing a carbonated beverage in a self-regulating and constant pressure maintaining product dispenser assembly including a product container that includes a bottom and an open top, wherein an inner space is defined within the container between the bottom and the top, the method comprising the following steps: providing an amount of an adsorption material maintained in a dry environment within the inner space, the adsorption material having adsorbed a specific amount of a propellant gas;placing a flexible bag on the bottom of the container within the inner space of the container, the flexible bag defining a pressure space within the flexible bag and a product space configured to contain the carbonated beverage within substantially all of the inner space between the pressure space and the top of the container, the pressure space being exposed to the adsorption material;filling the product space with the carbonated beverage;attaching a dispensing tap to the open top of the container so as to be in fluid communication with the product space; andfilling the pressure space with the propellant gas to an initial pressure of 0.1-3.0 bar above atmospheric pressure when subjected to a temperature in a temperature range of 0° C.-90° C., wherein the specific amount of the propellant gas adsorbed by the adsorption material is sufficient for allowing the flexible bag to expand, thereby increasing the volume of the pressure space so as to substitute at least some of the product space with the increasing volume of the pressure space when the carbonated beverage having a temperature in the temperature range is being dispensed from the product space by flowing through the dispensing tap, while substantially maintaining the initial pressure in the pressure space during a complete substitution of the product space by the pressure space, the amount of the adsorption material being inherently capable of substantially maintaining the initial pressure in the pressure space by: releasing the adsorbed propellant gas into the pressure space when the pressure in the pressure space is decreased below the initial pressure due to a temperature drop in the pressure space; andre-adsorbing the propellant gas from the pressure space when the pressure in the pressure space is increased above the initial pressure due to a temperature increase in the pressure space. 2. The method of claim 1, wherein the initial pressure is not more than 2 bar above atmospheric pressure. 3. The method of claim 1, wherein the pressure space, after the complete substitution of the product space by the pressure space, has a pressure above atmospheric pressure of at least 60% of the initial pressure. 4. The method of claim 1, wherein the product space initially occupies at least 70% of the inner space. 5. The method of claim 1, wherein the adsorption material inherently adsorbs the propellant gas when the container is heated to a temperature above the temperature range. 6. The method of claim 1, wherein the container and the dispensing device are made of a material selected from the group consisting of disposable polymeric materials and combustible polymeric materials. 7. The method of claim 1, wherein the carbonated beverage in the product space has an initial mass, and wherein the amount of the adsorption material has a mass approximately 1%-10% of the initial mass of the carbonated beverage in the product space. 8. The method of claim 1, wherein the adsorption material comprises activated carbon. 9. The method of claim 1, wherein the carbonated beverage in the product space has a defined volume at atmospheric pressure, and wherein the amount of the propellant gas initially adsorbed by the adsorption material has a volume equal to 1-3 times the volume of the carbonated beverage in the product space at atmospheric pressure. 10. The method of claim 1, wherein the propellant gas is selected from the group consisting of one or more of CO2, N2, He, Ne, Ar, propane, butane, isobutene, dimethylether, methylethyl ether, and hydrofluoroalkanes.
