Abstract
A cassette storage container for covering a tape cassette, the container having a case body formed by a plastic resin sheet of transparent or semi-transparent material which comprises a multiplicity of projections in the form of ribs or verrucae formed on the inner face of the case body for providing a rough surface and an opaque layer formed on the outer surface of the case body, the area of the opaque layer being at most covering the entire surface area of the outer surface of the container except for at least the portion corresponding to a label of the tape cassette put in its stored position in the container so as to define a display window for displaying the label of the tape cassette.
