Abstract
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.
