Abstract: The invention relates to a structure comprising at least two sets of folds which is made from laminated materials, such as paper, board, plastic, metal or any other material that is sufficiently rigid and flexible in order to be structured and folded. Each of the aforementioned sets of folds is formed by one curved fold and another straight fold which are folded in opposite directions. The purpose of the invention is to provide a novel pressing or clamping mechanism and a hinge mechanism which is intended for use in the design of articles such as plates, containers, clamps, articles bearing laminate objects and/or volumes, packaging and lamp shades and for use as a hinge device for articles such as doors and lids or with hinged parts. According to the invention, the structure comprises folds which are made from the central area of the laminate, which forces the outer area of said laminate to form the walls of the structure and, thereby, prevent spillages.
