PROBLEM TO BE SOLVED: To provide a cap that allows contents to be discharged smoothly to the outside when the contents are used, and allows the inside of a container to be kept in a sealed state without operating manually after the contents are used.SOLUTION: A cap main body 4 of a cap 1 is constituted of: a cylindrical inner wall part 19 fitted to an inner wall surface of a container mouth part 3; an annular wall part 10 that extends obliquely upward integrally toward a center in a radial direction from the inner wall surface of the cylindrical inner wall part 19, has a truncated conical lower wall surface and has a discharge hole 25; a check valve 12, arranged above the annular wall part 10, whose valve part 36 is separated from or seated on an annular valve seat part 26 so as to open/close the discharge hole 25; and a tubular guide body 13 that is arranged above the check valve 12 and has a discharge passage 41 for contents from the discharge hole 25. This allows the contents to be discharged smoothly to the outside when the contents are used, and allows the inside of a container 2 to be kept in a sealed state without requiring manual operation by a user after the contents are used. |
