摘要: Method of packaging a beverage and package structure has cylindrical tube 1 over an end 3 which is located partition 2 having restricted orifice both are sealed, for example by crimping, to the rim 1. Primary chamber 4 formed within secondary 8 between closure 7 chambers communicate through 6. Chamber charged with 11 containing gas in solution sealed wall 12 crimped 9 Prior sealing dosed liquid nitrogen or carbon dioxide so that headspace 13 pressurized. The adjusts state equilibrium flows into form 14 therein. Upon opening pull tag 15 pressure differential headspaces causes and/or be ejected 6 thereby liberated form, assist formation of, head froth on beverage.
