Abstract
The present invention relates to a container device that is useful for separately storing two ingredients, typically a solid ingredient and a liquid ingredient, and subsequently mixing the two ingredients within the container device. The container device is especially useful for the storage of a solid ingredient that can be degraded during storage, by moisture, and a liquid ingredient wherein, when such ingredients are mixed, the mixture is stable for only a short period of time.
