PROBLEM TO BE SOLVED: To provide a lid to prevent mistaken swallowing by a third party or an infant by making it difficult to open/close the lid when the lid is turned. SOLUTION: Several projections 2 are circumferentially provided on a container mouth part 1, and inclination is provided on the lowest projection in the right-to-left direction. A projection 6 as wide as a recessed part 3 is internally provided on a lower part of an upper lid 5. The projection 6 in which the recessed part 3 of the projections 2 circumferentially provided on the container mouth part 1 is detached by lifting the upper lid 5 while turning it in the right-to-left direction, and when lifting is stopped, the lid continues turning between the next circumferential projections. The lid can be detached from all recessed parts 3 and can be opened by lifting the lid while turning it. |
