The cover sheet includes plural closures (34) releasably secured to one another along weakened lines (38). The barrier sheet is formed of a moisture impervious plastic and has a central portion (56) and edge portions (58, 60, 62) each including an adhesive (40) on its underside surface. The central portion includes weakened lines (66) corresponding to the weakened lines in the closures of the device, In one embodiment, each of the edge portions are narrow elongated flaps. The barrier sheet is secured to the cover sheet by disposing it on the cover sheet with the flaps folded around the edges of the cover sheet and into securement with the device base to seal the edges of the cover sheet. In another embodiment, the central portion of the barrier sheet includes an array of openings (232) to receive the compartments of the base and the flaps (212-218) are arranged to fold over and completely cover the cover sheet. In another embodiment, a primary moisture impervious cover sheet (300) is provided.The primary cover sheet includes a foil layer (304) on the underside of a paper layer (302). The underside of the foil layer includes a pressure sensitive adhesive (308) for securing the cover sheet to the base of the medicinal dispensing device.
