To reliably achieve a protective action or the like of an outlet in a trigger-operated content ejection mechanism, and also prevent solidification and dropping phenomenon occurrence of contents due to sealing action to the outlet, and further achieve user-friendliness by using the outlet as a fixed position.

A trigger operating member 5 having an upper edge side inner surface 5d for covering an outlet 8d to protect and seal it is turnably attached to a cover 4 for protecting the outlet 8d and a flexible pipe 7 in communication with this, when being set in a stationary mode position by the action of a leaf spring 9. When the trigger operating member 5 is turned in the content ejection operation, at first, the leaf spring 9 is displaced against the elastic force to expose the outlet 8d. Then, as an exposure state of the outlet, a cam operating part 5j comes into abutment with an internal projecting section 9c, and drives downward a stem joint 6 along with a stem 3 to eject the contents from the outlet 8d.
