<p>A pouring member (1) provided with an unsealing mechanism which is configured so as to enable unsealing operation to be performed by the rotation of an unsealing cap, wherein the pouring member (1) is provided with a pouring member body (2) having a pouring cylinder section (22) rising in a circular cylindrical shape from a base section (23), and is also provided with the unsealing cap (3) mounted concentrically to the pouring member body (2). An engagement protrusion (3d) is formed on the opening end-side inner peripheral surface of the unsealing cap (3), and a three-sided protrusion (5) engaging with the engagement protrusion (3d) and surrounding three sides of the engagement protrusion (3d), that is, the top, left, and right sides of the engagement protrusion (3d), is formed on the base section (23)-side of the pouring cylinder section (22). As a result of this configuration, erroneous unsealing caused by unintended rotation or pulling out of the unsealing cap can be reliably prevented.</p> |
