The packing or container incorporates a primary chamber (12), which has a dispensing opening at the bottom of the can, and a secondary chamber, at the top, which takes up the gas. The secondary chamber is connected via a small aperture (11) to the primary chamber When the dispensing opening is opened, the pressure in the primary chamber will drop, gas will escape from the secondary chamber and squirt into the drink. The container is initially filled when upright with the dispensing opening at the bottom. The secondary chamber is formed by placing a lid (10) near the top, after which a final top, which closes the container, is placed in position.
