Abstract A spout for a liquid container which has an outer tube and an inner tube and which can hold drip from the spout without allowing it to flow over the upper edge of the outer tube and can be molded by use of a metal mold simple in construction. A plurality of reservoir forming members are arranged along the inner wall of the inner tube at regular spacings so as to extend vertically. The liquid on the guide plate between the inner tube and the outer tube is trapped in the reservoirs formed by the reservoir forming members.
