Abstract: A dispenser-cover adapted to replace existing auxiliary caps on containers for granulated or powdered coffee or other material in particulate form, the cover serving to discharge a metered amount of such material. The cover is constituted by a cap attachable to the mouth of the container, the cylindrical side wall of the cap having an opening therein which receives a trough-like spout whose apex is pivoted to the side wall. Extending across the upper section of the spout is a divider that partitions the section into two zones, such that when the spout is swung open to expose the front zone and the container is tipped over, particulate material lying in the lower section of the spout whose capacity is equal to one teaspoon or any other predetermined measure, is discharged through the open zone, the divider blocking the discharge of additional material.
