Abstract
The disclosure relates to a sealing unit for sealing a container wall opening. The sealing unit comprises inner and outer housings defining a gas flow passage arranged between an outer surface of the inner housing and an inner surface of the outer housing. The inner housing is movable in axial direction between a first axial position wherein the gas flow passage is closed and gas is prevented from flowing into or out of the container and a second axial position wherein the gas flow passage is open and gas is allowed to flow in a generally axial direction into or out of the container. The sealing unit also includes a biasing element arranged between the outer and inner housings and configured to urge the movable inner housing to move to the first axial position. A liquid flow passage including a liquid seal unit is defined inside the inner housing.
