Embodiments of a measuring and dispensing device are described, for attachment to an open container for neat and consistent dispensing of particulate. The device has a generally cup-shaped dome with a swinging and lockable partition inside the dome for changing the volume inside the dome that receives particulate. A lid snaps onto the bottom of the dome to separate the dome interior space from the open container. To prepare the dispenser for receiving and measuring particulate, the dome is rotated relative to the lid to align an inlet port in the lid with the selected dome volume, and the container-dispenser unit is turned up-side-down. The dome then is rotated to close off the inlet port against a blocking surface, and the particulate is poured out through an uncapped outlet port. The device features simple, smooth construction, which results in easy cleaning and sanitary use.

A device for dispensing predetermined equal amounts of coffee into the reservoirs mounted to the upper termination of the lower detachable portion of an expresso coffee pot. The device is adapted to securely receive the open end of a cylindrical coffee container on one end and the other end has several concentric recesses that cooperatively receive the upper termination. A dispensing member with hemispheric shape is rotably mounted within the device to cover the opening of the smaller one of the concentric recesses with the convex side and capable of dispensing a predetermined amount of coffee when rotated with an externally accessible handle member.
