The device includes a substrate; at least one reservoir disposed in the substrate, the reservoir having two or more openings; reservoir contents located in the reservoir; two or more discrete reservoir caps, each reservoir cap sealingly covering at least one of the reservoir openings; and control means for selectively disintegrating or permeabilizing the reservoir caps.
