Method of enforced the sideward support of hollow articles

The invention is a method of enhancing the sideward support of hollow articles, which effectively improve the stability of a thick hollow article. A hollow article empowered with this invention having an upper surface, a lower surface and a sideward surface. Said sideward surface connected with said upper and lower surfaces to form as a hollow article. The upper (lower) surface having at least one selected area to form a recess, said recess including a projected surface which toward the opposite surface of said upper (lower) surface and a support surface which extend from said upper (lower) surface, and further connected with and encircled said projected surface. The characteristic of this invention is that at least one portion of said support surface be integrated with said sideward surface to form as a support structure which enhance the support function of said sideward surface.
