After such use, the content liquid remains in the lateral hole 14d. However, since the horizontal hole 14d is always in communication outside the valve pipe 14, the contents are easily moved and hard to accumulate, and the length of the horizontal hole 14d is short, so that the remaining amount of the liquid content is small. In addition, since the upward step 14g is an inclined surface, the contents of the side hole 14d can easily move toward the internal passage 14j. Therefore, it is difficult to close the horizontal hole 14d with the contents.
