Abstract: A container closure is composed of a closure body, an outflow tube, and an outer cap. The outflow tube is pivotably mounted on the closure body. The outer cap is mounted on the closure body pivotably between a closed position and an open position. When the outer cap is pivoted from the closed position toward the open position, the outer cap contacts the outflow tube located at the closed position to erect the outflow tube from the closed position to the outflow position. The outer cap is then separated from the outflow tube and brought to the open position. When the outer cap is pivoted from the open position toward the closed position, the outer cap contacts the outflow tube located at the outflow position to tilt the outflow tube from the outflow position to the closed position, and the outer cap is also brought to the closed position.
