MW/JLB/90B135 ABSTRACT DISSOLVING A GAS IN A LIQUID Carbonated ale is pumped by pump 50 through a device 52 for dissolving a mixture of carbon dioxide and nitrogen therein. The partial pressure of carbon dioxide in the mixture is selected so as to maintain or achieve a chosen concentration of carbon dioxide in the ale. The ale passes to a tank 56 in which it is held for at least 10 minutes under a nitrogen pressure. The ale is then passed to a filler from which it is charged into flexible, thin-walled cans which are then closed. In each can, after its closure, dissolved gas comes out of solution to create therein a superatmospheric internal pressure that resist deformation of its walls during normal handling.
