<p>The purpose of the present invention is to provide a beverage container capable of maintaining the release of pressure in the beverage container in an effective manner over a long period and effectively prevent problems such as leakage of a beverage in the beverage container. This is achieved by a beverage container (1) having: a container body (2); a middle lid (3) covering the container body; a drinking port (8) formed in the middle lid; a drinking port blocking part for blocking the drinking port; an outer lid (5) disposed so as to detachably engage with the middle lid; a vent part (10) for creating passage of air with respect to the exterior of the container body; and a release operation part (12c) for causing disengagement between the outer lid and the middle lid. The beverage container is provided with a blocking and venting part (12c) disposed at a blocking position at which the vent part is in a blocked state when the outer lid is disposed relative to the middle lid so that a closed state is obtained, and disposed at a vent position at which the vent part is in a venting state when the release operation is performed by the release operation part. At least a part of the blocking and venting part functions as a vent-creating part (12hb) for creating a vent channel between the vent part and the exterior when the blocking and venting part is at the vent position.</p>
