ABSTRACT:
A beverage package and a method of packaging a beverage such as beer containing gas in solution has a container can 1 having a primary chamber 1A charged with beer 14 to form a small headspace 15. The can 1 is sealed and includes a submerged insert 8 forming a relief chamber 6 which is sealed by a closure 11. The insert 8 is responsive to heat applied during pasteurization which causes the closure 11 to open the relief chamber so that the latter can accommodate beer derived from the primary chamber 1A to provide an enlarged headspace 15A. The small headspace 15 initially provided facilitates removal of air therefrom prior to sealing of the container while the enlarged headspace 15A is adequate to accommodate froth or foam developed by the intentional liberation of gas from solution in the beer. An insert part 7 forming a secondary chamber 5 may be provided for injecting gas or liquid into the beer to liberate gas therefrom for froth or foam development in the enlarged headspace. The relief chamber 6 may contain gas under pressure so that when opened to the primary chamber the release of such gas pressurizes the enlarged headspace 15A. The insert part 7 may be located within the relief chamber 6.
