A fixed volume discharge device adapted to be mounted to a container, and having a first chamber communicating with the interior of the container and a second chamber communicating with the atmosphere, the first chamber and the second chamber communicating with each other through a restricted opening. A liquid or powder stored in the container flows into the first chamber when the container is downwardly inclined, and then flows into the second chamber from the first chamber when the container is returned in its normal attitude. Thus, when the container is again downwardly inclined, the liquid or the powder within the second chamber is discharged while the liquid or the powder in the container flows into the first chamber, thereby a predetermined fixed volume liquid or powder is obtainable through the fixed volume discharge device each time the container is downwardly inclined. The fixed volume discharge device is adjustable in the amount of its predetermined discharge volume, and has a size and shape suitable for a container such as a bottle to which the fixed volume discharge device is mounted.
