ール面形状が異形化してシール性を損なう。When the cap is formed by injection molding or the like, the dimensional accuracy of the spout and the spout varies due to the occurrence of sink marks and the like, thereby impairing the sealing property of the spout. Even with the conventional technology in which the spout is made thin, if the above-mentioned variation in dimensional accuracy becomes excessive, the elastic deformation of the spout itself to cope with this variation becomes excessive, and the sealing surface shape of the spout becomes irregular. And the sealing property is impaired.

The outer cap 21 has a cup shape having the same outer diameter as the outer cylinder 21 and is fitted to the annular projection 27 of the base cap 11 in the closed state. The cover cap 12 is provided on the opposite side of the hinge 13 with a locking portion 31 that locks with the annular projection 27 of the base cap 11.
And an opening projection 32 serving as a clue when opening.
On the inner surface of the cover cap 12, a spout plug 33 corresponding to the spout portion 26 of the base cap 11 and being pressed against and sealed to the spout portion 26 is provided.
