Abstract:
A foldable DVD case comprising:a) case sections joined to form an integral body, one of said case sections on a first side defining a circular well having a bottom surface and with a generally-circular center hub extending upwardly from the bottom well surface for receiving a DVD disk having a center hole,b) said integral body comprising a vacuum formed sheet member of relatively rigid thermoplastic material forming said first case side,c) said center hub being an integral part of the vacuum formed sheet member and comprising three projections connected by valley regions to a button-shaped center, each of the three projections having along an outer edge an outwardly-extending detent region, said hub having a first stable up position wherein the detent regions define a circle whose diameter is slightly larger than the diameter of the disk hole, a first generally horizontal annular region being an integral part of the vacuum formed sheet member and surrounding the hub and connecting the hub to the well surface,d) said hub and first annular region being configured such that, when the hub is depressed to a down position, the three projections flex inward defining a circle whose diameter is the same as or less than that of the disk hole, the hub when in its down position being unstable,e) said hub and first annular region being configured such that the hub elastically toggles in a one-way toggle action between its up position when not depressed and its down position when depressed without the aid of external resilient members capable of supplying a restoring force on the hub and the region immediately below the first annular region and the hub being free of such resilient members.
