US Patent 8235207 Jigsaw puzzle transporting system

A jigsaw puzzle transporting system having a bottom part, a base plate and a lid is provided. An at least substantially vertically projecting frame is present on the bottom part for peripherally surrounding the base plate. A shoulder with a holding face fitting into the frame projects from the lid. Side faces, mutually facing in a closed position, of the shoulder and of the frame cooperate for releasably locking the shoulder in the frame. The shoulder in the closed position is positioned, relative to the base plate received in the frame, such that a distance between the holding face and an upper surface, facing the latter, of the base plate is less than a jigsaw puzzle piece height.
