<p num="1">Disclosed is a pouring spout of the type comprising an inlet tube devised to be detachably connectable to the container for receiving the liquid stored therein and an outlet tube slideably connected to the inlet tube for guiding the liquid from the inlet tube to a receiving container. A liquid duct through which the liquid stored in the container can flow, is part of both the inlet tube and outlet tube. An air duct through which air can come freely inside the container, is also part of both the inlet tube and outlet tube. Such considerably reduces vacuum formation within the container and allows faster liquid transfer through the liquid duct. A valve system is provided for simultaneously opening the liquid duct and the air duct when the outlet tube is slideably moved relative to the inlet tube. An internal spring is also provided to keep the inlet and outlet tubes in such a position with respect to each other as to keep the valve system closed unless a pressure is applied to the outlet tube in order to slideably move it relative to the inlet tube. In accordance with the invention, the valve system is devised so as to cause the liquid duct and the air duct to open separately into the storing container. Such allows the liquid stored in the container to flow out freely out of the same through the liquid duct, and air to separately enter into the container via the air duct, thereby preventing any interference.
