To provide a liquid pour-out nozzle capable of preventing dripping from a liquid container.SOLUTION: There is provided a liquid pour-out nozzle 1 for discharging liquid from a liquid container, in which the nozzle is a flat head tubular body, and has a base part 11 and a tip part 12 for mounting the nozzle on a mouth of the liquid container. A hollow inside of the base part is an internal passage 112 through which liquid passes. The tip part has an inner surface composed of a plurality of stages of curved surfaces extending from the internal passage and continuing to a nozzle outlet. The plurality of stages of curved surfaces each have such a straight line that an angle formed by the straight line and a tube axis in a cross section including the tube axis is αi°, and that the angle αi° formed by the straight line and the tube axis becomes larger sequentially from the internal passage side to the nozzle outlet side. Further, a projecting part 111 is disposed over the whole circumference at a predetermined position of an outer surface of the base part so as to prevent excessive insertion of the base part of the nozzle.SELECTED DRAWING: Figure 1 【課題】液体容器からの液垂れの発生を防止できる液体注出用ノズルを提供する。【解決手段】頭部平坦の管状体で、液体容器の口部に装着する基部１１と先端部１２とを備え、液体容器から液体を注出する液体注出用ノズル1とする。基部の中空内部は液体が通過する内部通路１１２とし、先端部は、内部通路から延在しノズル出口まで連続する複数段の曲面からなる内部表面を有する。複数段の曲面は、管軸を含む断面で管軸とのなす角度がそれぞれαi°となる直線状を呈する曲面とし、かつ管軸とのなす角度αi°が内部通路側からノズル出口側に向かって、順次、大きくなる角度を有するように構成する。さらに基部外部表面の所定の位置に、全周にわたり突状部１１１を設け、ノズル基部の過挿入を防止する。【選択図】図１
