Beverage container assembly for holding a beverage

A method of producing and filling a beverage container assembly comprising the steps of:

• providing a preform assembly comprising an outer preform defining a body portion and a cylindrical neck portion connected to said body portion, said cylindrical neck portion defining a rim located opposite said body portion, said preform assembly further comprising an inner preform being sealed together with said outer preform at said rim of said cylindrical neck thereby defining a first space within said inner preform and a second space between said inner preform and said outer preform, said inner preform comprising a beverage conduit located adjacent said neck portion between said rim and said body portion of said outer preform for providing fluid communication between said second space and the outside of said preform assembly;
• integrally blow molding said preform assembly to form a beverage container assembly by causing said inner preform to form an inner bag and said outer preform to form an outer container, thereby causing said first space to form a pressure space and said second space to form a beverage space;
• filling beverage into said beverage space thereby compressing said inner bag;
• and
• sealing off both said inner bag and said neck portion of said outer container at a location between said rim and said body portion, while establishing fluid communication between said beverage space and the outside of said beverage container assembly.

A method of dispensing beverage from a beverage container assembly comprising (i) an outer container defining a body portion and a neck portion connected to the body portion, the neck portion defining a rim located opposite the body portion;

• (ii) an inner bag positioned within the outer container and defining a pressure space inside the inner bag and a beverage space between the inner bag and the outer container, the beverage space being filled by beverage;
• and (iii) a cap sealing off the inner bag and the neck portion at a location between the rim and the body portion, the cap comprising a beverage passage establishing fluid communication between the beverage space and the outside of the container assembly;
• the method comprising the steps of:
• (a) causing pressurized gas to enter the pressure space, thereby causing the inner bag to change from a compressed state to an expanded state;
• and
• (b) causing the beverage to be dispensed from the beverage space via the beverage passage to the outside of the container assembly in response to the change of the inner bag from the compressed state to the expanded state.
