A container for self-cooling the liquid contents of the container comprises a cartridge for a pressurized refrigerant gas, and a conduit leading from the cartridge to a gas discharge port on the container and passing through the interior of the container to cool its liquid contents when the gas is discharged to the atmosphere via the port. The container further includes a valve normally closed but manually openable to initiate a rapid discharge of the gas via the conduit and thereby to cool the liquid contents of the container.
