The air remaining within a headspace of a can filled with a liquid such as a carbonated drink, juice drink, tea drink, coffee drink or the like is replaced with one of steam, a mixture of steam and carbonic acid gas, a mixture of steam and nitrogen gas, and a mixture of carbonic acid gas and nitroge

The air remaining within a headspace of a can filled with a liquid such as a carbonated drink, juice drink, tea drink, coffee drink or the like is replaced with one of steam, a mixture of steam and carbonic acid gas, a mixture of steam and nitrogen gas, and a mixture of carbonic acid gas and nitrogen gas. Therefore, the quality of filled liquid can be maintained, and deterioration of the working environment can be prevented by avoiding the spraying of carbonic acid in all directions at the workshop.
