[origin: EP3666678A1] There is provided a spout assembly capable of ensuring good sealing properties with a structure in which the spout has no closure plate and to provide a packaging container having the spout assembly. The spout assembly includes a spout and a cap. The cap includes an inner ring having an outer peripheral surface that is provided with a first region having a first outer diameter and a second region having a second outer diameter. The spout includes a side wall having an inner peripheral surface that is provided with a first region having a first inner diameter and a second region having a second inner diameter. In a state in which the cap is threadably engaged with the spout, the first region of the inner ring is in close contact with the first region of the side wall of the spout throughout the circumference, and the second region of the inner ring is in close contact with the second region of the side wall of the spout throughout the circumference. There is a space between an area where the first region of the inner ring is in close contact with the first region of the side wall of the spout and an area where the second region of the inner ring is in close contact with the second region of the side wall of the spout.
