A storage box includes a bottom casing, a top cover, two hinge coupling plates, and a button seat. Both the bottom casing and the top cover have an interior defining a chamber. The rear sides thereof are respectively provided with hinge coupling seats each of which is provided with fastening holes for engaging corresponding bulges on the leaves of the hinge coupling plates to allow opening or closing of the box. The front side of the bottom casing is provided with a fastener coupling seat for receiving the button seat. The front side of the top cover is provided with a fastening groove for engaging a projecting hook of the button seat. The hinge coupling plates are configured to be multi-piece coupling elements with contacts at the middle section thereof to ensure that the contacts will not easily break. The leaves of the hinge coupling plates are bendable. Each coupling element has a slot which is integrally connected to a reinforcing strip.
