Abstract
A container for tape cassettes is provided with one or more locking elements which comprise one or more ring segments which are roughly adapted to the drive orifice of the cassette. An advantageous embodiment is formed integrally with a web and, preferably, an ejector peg. Overlaps in the edge contour part of a joint and the height of the peg adapted to the internal dimension of the container provide greater stability to lateral compressive forces and forces acting during fall.
Claims18
In a parallelepiped container for a tape cassette, which tape cassette contains a longitudinal central axis, at least one hub for carrying tapes, which hub has a drive orifice, a housing containing the at least one hub for carrying tapes, and at least one drive opening having a circular shape in the housing through which the hub for carrying tape is engagable by driver means;
- the container comprising I) a bottom part comprising a bottom wall with at least one locking element for the at least one hub for carrying tapes in the tape cassette, at lest one back wall or front wall, and a side wall;
- and II) a lid part comprising one lid wall;
- the improvement comprising:
- the at least one locking element on the bottom wall contains 1) a ring segment extending less than 360.degree. between its two ends and having an upper surface which is parallel to the bottom wall, which ring segment has an exterior arc shape which substantially corresponds in size to the circular shape of the drive opening of the cassette housing for contact between the ring segment of the locking element and the cassette housing, and 2) at least one web which is of such height as to extend into the driver orifice of the hub for carrying tapes when the cassette is in place in the container and when said ring segment is in the drive opening.
In a container for a compact tape cassette, which tape cassette contains a longitudinal central axis, two hubs for carrying tapes, each hub having a driver orifice, a housing containing the two hubs for carrying tapes and two drive openings having circular shapes in the housing through which the hubs for carrying tape are engagable by driver means;
- the container comprising I) a bottom part comprising a bottom wall and two locking elements for the two hubs in the cassette and at least one back wall or front wall and a side wall, and II) a lid pat comprising one lid wall;
- wherein the bottom wall has a cut-out and the lid part has a receiving pocket for the compact cassette and a pocket front wall complementing the cut-out of the bottom wall, the improvement comprising:
- each of the two locking elements on the bottom wall of the container contains a ring segment extending less than 360.degree. between its two ends and having an upper surface which is parallel to the bottom wall, which ring segment has an exterior arc shape which substantially corresponds in size to the circular shape of each of the drive openings of the cassette housing for substantial contact between each ring segment and the cassette hosing, and each of the two locking elements contains at least one web which is of such height as to extend into the driver orifice of the hub for carrying tapes when the cassette is in place in the container and when the ring segment is in one of the drive openings.
