Abstract
A floatable oxygen-absorbing cartridge for placement into a container of liquid having an air space above the liquid level including a casing, a weighted base on the casing for causing the cartridge to float in an upright position with its upper portion above the level of the liquid, an oxygen-absorbing composition within the casing, and a permeable membrane on the upper portion of the casing exposed to the air space for permitting oxygen to pass therethrough to be absorbed by the oxygen-absorbing composition while preventing the passage of the liquid into the casing.
