The first flavor / cap

The first flavor

Soda contained in big bottle loses its carbonic acid fast which is a main reason of losing its taste. The reason why is that because the gas expands and when the cover is opened carbonic acid gas gets released from swollen bottle. The structure of "The first flavor" prevents the loss of carbonic acid and keeps the soda drinks always fresh.
After first drinking, Its piston movement pre release the oxygen to the bottle to reduce volume of bottle. Even if the bottle swells up after time is passed the carbonic acid gets released no more when the cover is opened. because the pre reduced space of the bottle provides enough sapce to expand.
