Patent number: 5660867Abstract: Devices are described for fitting into pressurized individually packaged beverages (typically canned beers, ales and stouts), by which gas at high pressure is stored within the package for jetting into the beverage as the package is opened to atmosphere. One embodiment comprises a length of tube (10) having a gas jetting orifice (14) which in use is submerged below the beverage in a pressurized can having a gaseous headspace, which can be used to charge the tube with gas during the passage of the filled can (16) along a conventional canning line, on which the can is inverted after filling which brings the orifice into the gaseous headspace.Type: GrantFiled: June 20, 1995Date of Patent: August 26, 1997Assignee: Courage LimitedInventors: Andrew John Reynolds, John David Skingsley, Stephen Michael Freshwater, John Kelshaw Conway, Peter Erich Cox, John Poley
