Abstract: A modular panel fabricated or injection moulded to have a planar face one end of which is stepped to form a rebated end, the edges of the planar face each having a lip formed integrally therewith, the lips adjacent the rebated end also being rebated so that, in use, adjacent similar panels can be fitted together with the rebated end engaged within the lips formed in the other end of the adjacent similar panel. A box, container or cabinet formed from a plurality of similar modular panels as define a together with at least a back panel and hinged door panel.
