PROBLEM TO BE SOLVED: To prevent a lid from being easily opened due to any improper operation or the like, to clarify operation and a closed state of a locking mechanism, and to prevent scattering of content from a top end of a straw in a straw container.SOLUTION: A plug includes a plug body 11 pivotably supporting an openable/closable lid 7, a locking part 8 disposed to hold the lid 7 in a closed state and release the closed lid, a tap member 22 engaged with the plug body 11, and a blocking member 14 abutting on a container opening 3 to block the container body. The blocking member 14 is engaged with a hole 34 passing through the plug body 11 in thevicinity of a fitting part of a turnable handle member 26 pivotably supported by the plug body 4. A vent hole 35b is formed in a passing-through part. The vent hole 35b is in a closed state when the lid 7 is in a closed state. In a process in which the turnable handle member 26 is turned in the circumferential direction, the vent hole 35b is temporarily in an opened state. By further turning the turnable handle member 26, the vent hole is in a closed state again. Thus, the closed state is clarified, and the operation time of closing, opening, and closing the vent hole 34 can be reliably delayed. |
