Abstract: An enveloping hinge system and method for use on storage boxes, fishing tackle boxes, tool boxes and the like is disclosed. The enveloping hinge system and method comprise four identical links, each with a male end and a female end. Each said end is provided with a pivot point for joining to the next link, as well as providing a rotational axis on the order of 90.degree.. When open, the invention generally provides a flat surface for which to access the contents of said storage box. When closed, the invention generally provides a closed shape in which the bottom surface of each storage unit provides an outer surface of a 360.degree. shape to allow for storage and transportation requirements.
