Abstract

A beverage package and a method of forming such a package has a can 1 within a primary chamber 5 of which is located an insert 6 having a secondary chamber 10. The insert has a seating in the form of a bore 11 within which is received the lower end of a tube 15. The tube 15 is fitted to the insert whilst the latter is positioned in the can. When the can is charged with beverage such as beer 20 having gas in solution and sealed to form a headspace 21 containing gas at a pressure greater than atmospheric, beer from the chamber 20 may fill the tube 15. The secondary chamber 10 contains gas at a pressure greater than atmospheric and on opening the container the headspace 21 de-pressurises causing beverage and/or gas from the secondary chamber to be ejected through the tube 15 and such ejection causes froth to be developed in the headspace 21. The tube 15 isolates a major part of the beer in the container from having its gas liberated so that such gas can evolve gradually to provide sparkle in the beer when the latter is poured into a glass. The tube is preferably press fitted into the socket 11. In an alternative arrangement the tube may be received on a spigot extending from the insert 6. Preferably the seating 11 is co-axial with a cylindrical can 1 and the tube 15 is curved to locate its upper end adjacent to the side wall 3 of the can.
