摘要： 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 including a narrow opening through which a liquid or a powder stored in the container flows into the first chamber when the container is downwardly inclined, and the second chamber communicating with the first chamber through holes provided in a partition wall between the first and the second chambers below the narrow opening so that the liquid or the powder trapped within the first chamber flow into the second chamber through the holes 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 from the second chamber while a liquid or a powder in the container flows into the first chamber in the manner described the above, thereby a predetermined fixed volume liquid or powder is discharged from the container through the fixed volume discharge device each time when the container is downwardly inclined.
