Device for storing and releasing a substance

摘要

A cap is provided for storing powder and releasing it into a bottle. The cap comprises a cap top and an inner cap member which fits partially within the cap top to form a closed cavity for storing the powder and the cap is secured over the neck of the bottle. In use, the cap is rotated in an anticlockwise direction so that the cap top is rotated and raised relative to the inner cap member so as to open the cavity, releasing the powder stored therein into the bottle via the neck. The cap top is then further rotated in the anticlockwise direction so as to also rotate the inner cap member in the same direction, freeing the cap from the bottle.
