The present invention relates to a process for preserving carbonation of carbonated beverage during consumption from a carbonated beverage containing bottle, which has a relatively large amount of carbonated beverage therein and a bottle head with a bottle opening. A device including an airtight closed container having a volume smaller than the carbonated beverage containing bottle, which one end is provided with a connecting sleeve and another end provides with a sealing mechanism for selectively sealedly and airtightly closing the airtight closed container. An adapter is connected to the bottle head of the carbonated beverage containing bottle and the airtight closed container in an airtight manner, for selectively closing the bottle opening of the carbonated beverage containing bottle from an interior of the airtight closed container in an airtight manner and opening the bottle opening of the carbonated beverage containing bottle to enable an amount of carbonated beverage equal to or less than the capacity of the airtight closed container inside the carbonated beverage containing bottle to be poured into the airtight closed container without losing the carbonation.
