The inside plug is an injection molded article of synthetic resin, and includes: a cylindrical mounting part to be mounted on a mouth part of a container body; and a cylindrical pour-out part protruding upward from the mounting part and capable of pouring a liquid. The pour-out part includes: a cylindrical pour-out trunk part protruding upward from the mounting part; and a pour-out port part overhanging from an upper end part of the pour-out trunk part toward the outside in the diameter direction. The pour-out port part includes: a flange part overhanging in a flange-like manner from an outer peripheral surface of the pour-out trunk part toward the outside in the diameter direction of the cylindrical shape; and a mouth tip part extending downward from an outer peripheral part of the flange part. The lid includes: a lid top plate part for covering the upper side of the pour-out part in a closed state; and a close contact wall part suspending from the lid top plate part and coming into close contact with the outer peripheral surface of the mouth tip part of the pour-out part.
