  • Patent number: 5196216
    Abstract: A beverage package has a sealed can 1 containing beer 5 with gas in solution and a headspace 6 containing gas at a pressure greater than atmospheric. An insert 7 in the beer has a secondary chamber 13 containing gas at a pressure greater than atmospheric and which communicates through an aperture 15 with an intermediate chamber 14 having an open end 12 and containing beer 5A. On opening the container, headspace 6 depressurises causing gas to be ejected from chamber 13 through aperture 15 and gas to be evolved from solution in the beer 5A. Such evolution rises through the beer 5A to emerge into the beer 5 above the chamber opening 12 to form a head of froth. The open end 12 of the chamber 14 can be located in the headspace 6. The wall 9 of the chamber 14 isolates a major part of the beer in the container from having its gas liberated so that such gas can evolve gradually and naturally to provide sparkle in the beer.
