    • PROBLEM
      To provide a cap unit and a beverage container capable of suppressing unintentional opening of a ring member in a stored state and suppressing problems such as unintentionally closing a lid body and contacting with the face.
      RESOLUTION MEANS
      A cap unit (3C) attached to a mouth/neck part of a container main body (1C) open on a top part, containing: a cap main body (30) that closes an upper opening part of the container main body (1C) and has a liquid passage opening that communicates with an inner part of the container main body (1C); an annular ring member (33) provided above the cap main body (30); a hinge (32) that connects the ring member (33) to the cap main body (30) so as to be freely rotatable around a hinge central axis (A); a lid body (31) that covers the liquid passage opening provided between the main body (30) and the ring member (33) in a vertical direction, rotatably connected to the cap main body (30) via the hinge (32), in a state of being biased in an opening direction around the hinge central axis (A); a storage state holding mechanism (23) that holds the orientation of the ring member (33) in the stored state of the ring member (33) in which the lower surface of the ring member (33) and a lid top wall part of the lid body (31) face each other; and an open position holding mechanism (24) for holding the orientation of the lid part in an open position where the lid body (31) freely rotates in the opening direction around the hinge central axis (A).
