A very compact, stopper style pourer that can be inserted in a wide range of container neck sizes. The above mentioned end stopper is multifunctional, combining pouring, aeration, provision for preservation and capping in an integrated innovative design. The pourer is equipped with an internal aeration system, based on the Venturi principle, a non-protruding, non-drip spout, built inside the stopper, an access opening for a preserving gas supply, a telescopic extension in the container that regulates the aeration and improves the preserving gas usage. The stopper is also fitted with a hinged lid that has a co molded seal and lock, to provide a positive capping. The front face of the lid is suitable in size to carry any logo/marking, similar to any wine container cork-sleeve.
