Abstract: A carbonated canned beverage sealing device including a cover member having a circular member for positioning over an upper end of a beverage can. The cover member has an O-ring positionable inside the can rolled lip to effect a seal therewith. The circular ring has radial apertures each having rivets slidably disposed therein to abut the can below the rolled lip. A cap portion has a periphery for positioning over the cover member. Radially disposed tab housings extend outwardly and downwardly from the cap periphery in a spaced relationship corresponding with the rivets. Each tab housing has a hollow opening for receiving a rivet whereby the openings are positioned over the rivets. The cap portion-is rotated so that the rivets are pushed inwardly against the can below the can rolled lip to hold and effect a seal between the O-ring and the upper end of the carbonated beverage can.
