Abstract: A spout assembly includes a spout and a cap. The cap includes an inner ring having an outer peripheral surface provided with a first region with a first outer diameter and a second region with a second outer diameter. The spout includes a side wall having an inner peripheral surface provided with a first region having a first inner diameter and a second region having a second inner diameter. When 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.
