  • Patent number: 6364116
    Abstract: A puzzle carrier for use in the assembly and transportation of jigsaw puzzles, including a base or assembly tray and a plurality of sorting trays. The plurality of sorting trays have in the aggregate the same dimensions as those of the assembly tray. Each tray has a peripheral edge extending ⅛″ to 1″ above the surface thereof and each is provided with a foam insert fitting within the peripheral edge and extending upwardly of the peripheral edge by ⅛″ to 1″. At least one edge of the assembly tray is removable to facilitate removal of a finished puzzle. When the sorting trays are placed on top of the assembly tray with the foam inserts in place, the assembly is inserted into a carrying case having a peripheral zipper closure. When closed, the carrying case holds the assembly and sorting trays, together under compression against the foam inserts, thus allowing transport of the puzzle, without shifting of the trays or the puzzle pieces.
