Abstract
Sealing unit for selectively sealing and opening a container liquid opening in a liquid container for holding a liquid. The sealing unit comprises a tubular element comprising a liquid passage and a valve inside the passage. The valve comprises a tubular valve portion axially movable inside the passage between closed and open positions, and a valve skirt portion comprising a flexible skirt part configured to bend when the tubular valve portion is moved from the closed to open position under influence of an external axial force and to urge the tubular valve portion from the open to the closed position when the force is removed or reduced. The tubular element further comprises an air flow opening arranged to be covered by the valve skirt portion when the tubular valve portion is in the closed position and to be left open when the tubular valve portion is in the open position.
