摘要：
A capsule includes a compressible reservoir and a gas generating unit disposed in a housing. A threshold valve seals an opening in the housing, through which contents of the reservoir may exit the capsule. Gas generated by the gas generating unit increases pressure in the capsule, thereby compressing the reservoir. When a pressure acting on the threshold valve reaches a threshold pressure, the threshold valve opens, releasing contents of the reservoir.
