ABSTRACT:
A sealed self-piercing capsule for storing and delivering a substance, such as a medicine, comprises one or more barrier layers forming a sealed chamber for containing the substance. An internal puncturing mechanism is disposed within the capsule chamber for puncturing a barrier layer to release the substance from the chamber. The internal puncturing mechanism may comprise a sharpened edge located on a movable tube, which moves relative to a barrier layer forming the sealed chamber to puncture the barrier layer.
