The nozzle cylinder is inserted and the insertion cylinder part is inserted into the main body cylinder part of the extraction cap. At this time, the upper end portion of the nozzle cylinder presses the seal portion, thereby opening the inside of the insertion tube portion.
As described above, when the contents are poured out from the refill container, the plug cylinder portion of the refill container is inserted into the main barrel portion of the discharge cap, while the nozzle tube of the discharge cap is inserted into the plug barrel portion. As a result, it is possible to stabilize the posture of the refill container by suppressing the wobbling of the insertion tube portion.

  In addition, a connection hole that connects the flow hole and the air replacement hole may be formed in the main body cylinder portion.

  In this case, the connection hole is formed in the main body cylinder portion, and a series of large holes formed by connecting the flow hole and the air replacement hole by the connection hole are formed in the main body cylinder portion. It becomes possible to carry out smoothly, and this pouring cap can be easily manufactured without complicating the structure of the mold, for example.
