A way of packaging beverages in non-resealable containers which is especially relevant for packaging carbonated beverages such as lagers, ales, stout and carbonated soft drinks in metal cans (10) comprises placing an open-topped secondary chamber (1) with an orifice (6) in its wall into the open can or container (10) before or after the container (10) is filled with beverage, displacing substantially all of the oxygen from the open container (10) and the open-topped secondary chamber (1), and closing the open container (10) and, in so doing, closing the open-top of the secondary chamber (1). Thereafter, the only communication between the secondary chamber (1) and the inside of the container (10) is via the orifice (6). This enables the same oxygen displacement technique to be used as on conventional container filling equipment. Thus, for example, the oxygen may be displaced from both the container (10) and the secondary chamber (1) by flushing with a non-oxidising gas as part of the filling process. |
