    Abstract: A transparent window member for a tape cassette, which together with a reel pressure spring, forms a subassembly of the cassette. The reel pressure spring has a U-shaped central portion, the bight of the U being parallel to the plane of the spring arms, and the reel pressure spring having a longitudinal edge with two transverse slits spaced the same as the legs of the U of the central portion of the pressure spring. The central portion may thus be transversely inserted in the longitudinal edge of the window member and it thus forms a locating element for the pressure spring.

    Abstract: A packaging container (1) for a tape reel device, e.g. a tape cassette, which has one or more reel-locking elements (9, 10) possesses on at least one of these elements (9, 10) a friction element (14), e.g. of rubber, for holding and, if necessary, clamping the reel of the tape reel device. The element (14) can be annular, rib-shaped or knob-shaped, and can be used for any type of tape reel, inside or outside audio, video or film cassettes.
