PROBLEM TO BE SOLVED: To allow an ejection state of foam to be altered as necessary in a container including a foam ejecting pump. SOLUTION: A pump head 100 of a foam ejecting pump 10 is made in a double-tube structure comprising an outer cylinder member 110 and an inner cylinder member 120, while a small diameter ejection hole 121a and a large diameter ejection hole 121b are opened on a small diameter part 121 on an upper part of the inner cylinder member 120. An opening 115a is provided on a cylinder 115 extending downward from a top plate 114 of the outer cylinder member 110, the cylinder 115 is liquid-tightly inserted into the small diameter part 121, and the outer cylinder member 110 is attached to the outside of the inner cylinder member 120 so that it can relatively rotate. By rotating the outer cylinder member 110 with respect to the inner cylinder member 120, one of the small diameter ejection hole 121a and the large diameter ejection hole 121b is connected to the opening 115a, thereby changing an ejection state of bubbles. |
