PROBLEM TO BE SOLVED: To provide a reservoir-type administrating device for administrating a liquid or gel preparation, which contains a medicinal drug, through the skin or the mucosa. SOLUTION: In the reservoir-type administrating device, a drug reservoir is provided between a base material film and a release-controlling film layer, and an adhesive layer and a peeling liner are laminated on the surface opposite to the face where the release-controlling film layer is bound with the base material film. In this case, a drug reservoir-coating film is provided between the drug reservoir and the release- controlling film to prevent the leakage of a drug-containing liquid from the drug reservoir during the storage of the device. Furthermore, the drug-containing liquid can flow out on the side of the release-controlling film when used, since a means for releasing the drug reservoir-coating film is provided. This reservoir-type administrating device of the present invention having the reservoir-coating film between the drug reservoir and the release-controlling film can prevent the drug-containing liquid or gel from leaking out of the drug reservoir on the side of the release-controlling film during the storage of the device of the present invention, and thereby the reduction in adhesive force of an adhesive agent, the leakage of the drug-containing liquid or gel and the volatilization of a solvent can be prevented. |
