When lifting the container to disengage an engagement portion of the container from a top engagement portion of the hollow base and to compress an elastic member against a hollow guide disk, a rotary cap is rotatable with the container relative to the hollow base to adjust the gap between the grinding base and grinding disk of the grinding device subject to the desired ground powder particle size.
