ABSTRACT:
A housing for an audio or a video tape cassette is disclosed, including a housing body formed by a bottom rectangular panel which is slightly larger than the cassette. The bottom rectangular panel is connected to four depending side wall extending forward and perpendicular to the periphery of the bottom panel to form an enclosure with an access opening at the top of the housing body. A swingable tab is provided in at least one of the side walls proximate to the access opening. The swingable tab provides opening and closing of the enclosure and of the access opening to removably receive and hold the cassette therein. The swingable tab is connected to the side wall by a film hinge having an essentially curved or arcuate connecting portion with a reduced thickness which is substantially less than the thickness of the side wall and of the swingable tab. The swingable tab has a parabolic surface configuration. When the swingable tab is opened the swingable tab has an outward bowed convex configuration, with the convex surface extending outward from the side wall to permit an unobstructed access opening into the enclosure for removal or insertion of the cassette therein. When the swingable tab is pressed inwardly by the user the swingable tab is biased by the deformation energy being transferred through the integral film hinge to swing the swingable tab to an inward bowed convex configuration with the convex surface bowed within the side wall to hold the cassette within the enclosure.
