摘要:
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.

There is provided a bottle beverage packaging apparatus and method in which an open topped bottle 20 having a primary chamber charged with beverage 21 containing gas in solution is enclosed together with a closure 8 in a pressure chamber 25 which may be formed against a shoulder of the bottle. The chamber 25 is pressurised with nitrogen gas to pressurise the primary chamber and a secondary chamber 14 in the closure 8 through an aperture 15 of the chamber 14 prior to the closure 8 being displaced by a closure locator 5 to seal the open top of the bottle in the pressurised chamber 25. A projection 11A from the secondary chamber 14 extends into the beverage 20 to locate the aperture 15 beneath the surface thereof. Following sealing of the bottle the chamber 25 is de-pressurised and opened for removal of the sealed package. The chamber 25 may be formed by a tubular shroud 2 carried by a rotating carousel. The secondary chamber 14 may be formed in a hollow insert separate from the closure 8. There is also provided a beverage package in which the closure which may be fitted by the apparatus and system includes a manually openable vent that reduces a headspace pressure in the sealed package to atmospheric pressure for gas to be injected into the beverage through the aperture 15 for froth development prior to removal of the closure from the bottle.

摘要:
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 pasteurisation 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 pressurises the enlarged headspace 15A. The insert part 7 may be located within the relief chamber 6.

A sealed beverage package has a hollow insert 7 for developing froth on beverage 23 when closure cap 10 is removed from bottle 1. The insert 7 is carried through a socket and spigot coupling 9 on the underside of the cap 10. A barbed head 15 retains the spigot from withdrawal from the socket 17 and the socket and spigot coupling permits the insert 7 to swing on the cap 10.
