Abstract: A document filing case comprises a filing case body with a sliding cover. The cover includes a closure flap and a connecting or mounting panel having at least one track follower that is engaged in a track formed in the back panel. Each track is formed as a longitudinal slot in the back panel extending parallel to the side edges thereof. A latch mechanism is mounted on the free edge of the closure flap and is releasably engageable with a catch mechanism on the outside surface of the front panel of the filing case body. The track follower permits longitudinal, sliding movement of the filing case cover and allows it to be drawn over the top of the filing case body, whereupon the latch mechanism on the closure flap is secured to the catch mechanism on the front panel of the filing case body.
