A beverage package and a method of forming such a package.

摘要

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.
