摘要

To provide a spout with simple structure that can reduce amount of residual content.SOLUTION: A spout 30 includes an attachment part 32 mounted on a pouch 20, and an extension part 40 extending downward from the attachment part 32 for forming a content flow path to the inside of the pouch 20. The extension part 40 has, in at least an area in the up-and-down direction, a portion whose shape viewed from the lower side is asymmetrically formed in the pouch front-back direction Y when a virtual line parallel to the pouch left-right direction X is used as a reference.SELECTED DRAWING: Figure 1
