2. Description of the Related Art Conventionally, a cap attached to a spout of a container includes a cap body attached to the spout to seal the spout, and a separator connected to an opening side of the cap body. Are known. This separator is connected to the cap body when the cap is attached to the spout, but separates from the cap body when the cap is removed from the spout. By such separation of the separator, it can be recognized from the outside that the cap has been once removed.

[0003]

As described above, when the cap is removed, the separating body separates from the cap body. However, if the cap once removed is simply reattached to the spout by simply separating the cap, the cap may be removed. It is difficult to recognize the removal easily.

[0004] The present invention has been made in view of such a point, and once the cap is removed from the spout, the cap and the cap can be easily and reliably recognized from the outside. It aims to provide a union of outlets.
