The non-limiting embodiments described herein disclose a container and a cap. The cap seals a container while providing a separate internal storage area for liquid or power contents. A seal disposed at the bottom of the cap ensures that the storage area contents remain fresh and sterile until the cap is rotated to release the seal. The clockwise rotation and threaded engagement of the storage area with the lower cylindrical collar and the upper cylindrical collar releases the seal from the bottom of the cap, while centrifugal forces within the cap urge the storage area contents into the container.
