Abstract

A container having a viewing window essentially comprises a housing with a window which can be fastened to it and is designed in one part as a transparent part and in another part as a masking part, in particular in the edge region. The aim is to cover over the fastening points. In addition, the advantage is obtained of using windows with a wide variety of maskings for the same housing, provided that the contours of the cutout and of the outline of housing and window are adapted at least substantially to one another. The plastic container with windows can be used for all packing and archiving purposes, in particular also as a cassette with a recording medium, for example a magnetic tape cassette.
