Beschreibung
Zusammenfassung:	The external patch roll of the invention comprises a dispenser core and an external patch wrapped around the perimeter side thereof, and is provided with a pair of side covers attached to both edges of the dispenser core and covering both edge sides of the external patch roll, wherein the dispenser core and side covers are formed of plastic materials. The side covers inhibit escape of drug components from both edge sides of the roll, prevent inconveniences such as shape deformation of the roll, and enable smooth drawing out and winding up operations for the patch. Since the dispenser core and side covers are formed of plastic materials, loss of drug components due to adsorption or permeation into the materials can be greatly reduced.
