PROBLEM TO BE SOLVED: To surely prevent splash of remained liquid on the upper surface of a pouring section by a method wherein a part of a lower surface of an edge part when the cap is closed is received by a protrusion at the upper surface of the edge of the pouring section, and a clearance is assured at other portions of both of them. SOLUTION: There is provided a pouring structure comprised of a pouring section 1 having a liquid pouring hole 1a, and a cap 2 rotatably arranged at the pouring part. Protrusions (a semi-spherical protrusion 1d or rib-like protrusion and the like) are formed at intervals at the edge upper surface 1c of the pouring section 1 corresponding to the edge lower surface 2c of the cap 2. When the hole 1a is closed with a plug portion 2a of the cap as shown in the figure under a turning operation of the cap 2, the edge lower surface 2c of the cap 2 and the edge upper surface 1c of the pouring part 1 are contacted to each other at the semi-spherical protrusion 1d, and a clearance is formed at the lower part in the other part. By this constitution, the edge lower surface 2c of the cap 2 does not contact with the residual liquid, and the liquid is not splashed. |
