ABSTRACT:
A beverage package has a can 1 within a primary chamber 5 to which is located an insert 6 having a secondary chamber 10. The insert has a bore 11 within which is received a lower end of a capilliary tube 15. The can 1 contains beverage such as beer 20 having gas in solution and sealed to form a headspace 21 containing gas at a pressure greater than atmospheric. The tube 15 contains beverage and its upper end opens into the headspace 21. The secondary chamber 10 contains gas at a pressure greater than atmospheric and on opening of the container the headspace 21 de-pressurises causing beverage and/or gas from the chamber 10 to displace beverage through the restriction of the capilliary tube 15 directly into the headspace 21 causing froth to develop in the headspace.
