PROBLEM TO BE SOLVED: To prevent an unexpected exposure state transfer of a content discharge port covered so as not to be exposed to an external space area of a shut-off trigger mechanism.SOLUTION: In an illustrated lock mode (of checking content discharge operation), a stopper 8 locks a stem joint 5 fixed to a stem 4 and a trigger lever 7 for driving this. When rotating the stopper 8, an abutting state of a rectangular convex part 5g and a convex step part 8b of the lock mode and an abutting state of a lock action object part 7e and a lock locking upper end surface 8h are released. Here, when executing the content discharge operation by rotating the trigger lever 7 downward, a discharge port 5e is exposed in the first place, and afterwards, a C-shaped curved surface part 7g of the trigger lever 7 abuts on a low columnar part 5f of the stem joint 5, and the stem 4 is driven downward, so that the content is discharged from the discharge port 5e. An example of providing a lock mode setting-releasing slider in a top plate corresponding part of the stem joint, is also disclosed instead of the stopper 8. |
