A cap is attached to a container using a device with first and second disks mounted on opposite ends of a shaft, each disk having an opening. A cover cup is rotatably mounted on the shaft. When the container is inverted, rotation of the cover cup to a first position provokes alignment of the opening of an interior wall of the cover cup with the opening of the first disk, permitting material to flow from the container to the interior of the cover cup, and a subsequent rotation of the cover cup to a second position aligns the opening of the second disk with the opening of an end wall of the cover cup, to permit dispensing the material from the cover cup to a place of use.
