Abstract
A system for conserving a liquid substance (L) in a flexible receptacle (1), the substance being liable to be degraded and/or contaminated on contact with ambient air. The system includes a solid insert (3) whose outer envelope substantially matches the inside shape of the receptacle (1) in which the insert is immersed at least in part. The insert has bactericidal and/or chemical, especially antioxidant, activity and provides protective treatment by making contact with substance (L) over a large interchange area.
