    摘要: The invention is a floating vent device comprising a pair of members together defining a chamber, a gas permeable porous carbon body subdividing said chamber into two zones of which a first is provided with at least one aperture; a float connected with said pair of members so as to permit them to float above a body of liquid, and a tube projecting axially through said float, through said first zone and in air-tight fashion through said carbon body into said second zone. The other end of the tube is connected to a closure for a container and communicates with the outside atmosphere through an orifice in the closure.
