Abstract: A child-proof container and a closure for selectively opening and closing the container. The hollow container has at its upper end a dispensing opening. The closure has a body member and a flip-top cap member attached by a hinge to the body member for movement between open and closed positions. The body member is supported and locked on the container to permit rotational movement of the body member on the container. The container has an annular locking rib for releasable locking engagement with a locking bead on the cap member to permit unlocking of the cap member from the container only when the body member is rotated to an unlocking position with respect to the container, whereby the cap member may be moved from a closed to an open position to permit dispensing of contents from the container. The container and the closure are provided with corresponding indicia to indicate the precise rotational alignment of the container and the body member to permit unlocking of the cap member from the container.

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.
