PROBLEM TO BE SOLVED: To provide a spout for a container which is capable of being easily and hygienically opened without requiring a large force.SOLUTION: A spout 20 for a container is attached to a container body filled with liquid or powder content. When a second member 22 is relatively rotated to a first member 21 in a prescribed direction (one circumferential direction R1), a first slope rib 29 and a second slope rib 30 formed on the first member 21 are sequentially pressed by a pressing rib 38 formed on the second member 22, and a sealing plate portion 25 is displaced, and thereby, thin wall portions 25C and 25D of the sealing plate portion 25 are ruptured different timings at both ends as start points, and the inner cavity of the spout 20 for the container is opened. |
