CONSTITUTION:An ejection cap comprises a cap 2 with a lid 3 rotatably mounted, wherein a cock protrusion 15 provided at the tip of a coil-like spring 13 extending from a body is press-fitted to a lower end of an ejection hole 9 of the lid 3 to have them closed water-tightly, and the cock protrusion 15 is interlocked with a rotation of the lid 3 via a kind of a cam mechanism to have the ejection hole 9 opened/closed. In addition, also by pushing in a rod-like protrusion 16 standing on an upper face of the cock protrusion 15, the ejection hole 9 may be opened. |
