Sealed container

A sealed container, including a container and a container lid, wherein the container lid includes a lid body;

• a movable base that adapt to be moved up and down is disposed under the lid body;
• an elastic seal is disposed between the movable base and the lid body, and the elastic seal is connected with the lid body or the movable base;
• wherein when the movable base is moved upward, an outer edge of the elastic seal is deformed outward to be greater than a diameter of an sealing part of the container under an action of the movable base and/or the lid body, thereby preventing the movable base from continuing to be moved upward, so that the movable base presses the elastic seal on a neck portion of the container to form a sealing portion, and realizing sealing of the container lid and the container;
• an opening and closing mechanism for opening and closing the container lid is disposed on an upper side of the container lid, and the opening and closing mechanism includes a twisting switch and a sliding cover, wherein when twisting the twisting switch on the lid body, the movable base is moved up and down under an action of a lever force;
• and the twisting switch is connected slidably with the sliding cover, and the sliding cover adapt to slide relative to the twisting switch, so as to increase a length of a force arm of the twisting switch.
