  • Patent number: 5840377
    Abstract: A container is provided with a liner, such as a jigsaw puzzle, which is visible through translucent container walls. Retainers to hold the puzzle or puzzles in place against wall surfaces are panels in endwise engagement with one another. A modified form of retainer is a frame embodied in having a backing on which puzzle pieces are assembled and supported. Adhesive areas on the frame hold the frame and the assembled pieces in place against a container wall. Multiple positionable panels carried by a common base may also serve to retain the jigsaw puzzle pieces in place opposite a container wall. A method of providing a container with an assembled display is disclosed. The retainers may be of translucent material to render visible the inner surfaces of assembled puzzle pieces with a graphic display thereon.
