Provided is a pump stopper (E, F) including a substantially cylindrical-shaped stopper main body (35) provided with a side opening (38) in a manner such that the stopper main body (35) is C-shaped in an upper view thereof. The stopper main body (35) includes, on one of an upper end side and a lower end side thereof, a regulating portion (41) that prevents a tubular body (28) of a nozzle head (D) from being displaced downward, and, on another one of the upper end side and the lower end side thereof, a space portion (42) that allows the tubular body (28) of the nozzle head (D) to be displaced downward when the pump stopper (E, F) is inserted between a top wall (5) of an attachment cap (B) and the tubular body (28) of the nozzle head (D). |
