Shutter for covering a window opening in a case that contains a flexible disk

摘要

A shutter for covering the head window opening in a protective case that encases a flexible disk is manufactured from thinner and less expensive material and is made smaller in order to result in significant cost savings. The shutters are manufactured so as to form a band of connected shutters. The band of connected shutters is then wound to form a wound roll of shutters that are not susceptible to damage as a result of repeated contact with other shutters. Adjacent shutters can be connected to one another by strips of connecting material arranged in various manners.
