By the present invention, an inner lid is easily removed by upward thrusting of a sheath tube while detachment of the inner lid during storage is suppressed. An extraction cap is provided with: a cap body provided with a barrel part, a top-end part of which attaches to a mouth of a bottle container, and an air supply tube standing from a bottom portion of the barrel part and forming a first flow channel; and a sheath tube arranged and retained around an exterior of the air supply tube so as to be able to slide up and down. An inner lid is fitted on a top-end part of the air supply tube. An annular first retaining protrusion extending in the circumferential direction is formed on an external peripheral surface of the air supply tube, and a second retaining protrusion retained by the first retaining protrusion and comprising a plurality of retaining protrusions arranged at intervals in the circumferential direction is formed on an internal peripheral surface of the inner lid.
