Abstract
The present invention provides methods and apparatus permitting at least one hydrating liquid to be maintained in isolation and, when desired, permitting thorough release of the hydrating liquid. In particular, the self-contained hydrating system comprises a releasable seal for isolating hydrating liquid which can be progressively unsealed to release the hydrating liquid. The unsealing process involves an "unpeeling" of the releasable seal and, thus, does not involve breaking or rupturing of the seal material. In this manner, the hydrating liquid is made accessible but is never exposed to broken or ruptured sealing material. The self-contained hydrating system can be manufactured using existing equipment and techniques and can subsequently be easily associated with a separate device requiring hydration when desired.
