Abstract: A beverage package has a sealed container 1 containing beer 11 having gas in solution and forming a headspace 16 containing gas at pressure greater than atmospheric. A hollow insert 7 is located in the container and is responsive to a pressure differential developed on opening the top 5 of the container to inject beer and/or gas therefrom into the beer 11 whereby to liberate gas 17 from solution and form froth in the headspace 16. A baffle plate 12 on the insert 7 restrains the liberation of gas 17 to a minor proporation of the volume of beer 11 so that when the beer is poured into a glass, gas can evolve naturally from the beer to produce "sparkle". As an alternative to the beer and/or gas injection bubble initiation, gas from solution in the minor proporation of the volume of beer may be liberated by contact of that beer with a bubble initiating material.

Abstract: A beverage package and a method of packaging a beverage having gas (preferably at least one of carbon dioxide and inert (nitrogen gases) in solution has a non-resealable container 1 within which is located a hollow pod 4 having a restricted aperture 7 in a side wall. The container is charged with the beverage 8 and sealed. Beverage from the main chamber of the container enters the pod 4 (shown at 8a) by way of the aperture 7 to provide headspaces 1a in the container and 4a in the pod 4. Gas within the headspaces 1a and 4a is at greater than atmospheric pressure. Preferably the beverage is drawn into the hollow pod by subjecting the package to a heating and cooling cycle. Upon opening the container 1 by draw ring/region 13, the headspace 1a is vented to atmosphere and the pressure differential resulting from the pressure in the pod headspace 4a causes gas/beverage to be ejected from the pod (by way of the aperture 7) into the beverage 8.
