Abstract: The present invention relates to a method of forming images or decorations on a support comprising the following steps in sequence: arranging at least one support; applying at least one coloring material onto at least one surface of said support; coating said at least one surface with at least one protecting compound; causing said protecting compound to harden thereby forming an uninterrupted fixing and protecting layer for said at least one coloring material.
Abstract: The present invention refers to a new manufacturing solution for a plastic hinge which is particularly advantageous for manufacturing rigid cases, especially glasses cases, by giving it an absolutely original appearance and by using an absolutely new technique through which a snap opening and closing of the case is obtained, even with the type of plastic hinge which is applied to any type of rigid half-shells.
The main characterizing feature of the present invention is to provide for the manufacturing of a single plastic element 10 to join the two half-shells (A, B) of a case, said element 10 consisting of two surfaces to be fixed to the edges of the half-shells (A, B) and joined each other longitudinally by an intermediate U-shaped surface 13 having a minimum thickness suitable for giving it the necessary flexibility, said surfaces being further hooked together by one or more springs aiming to flex said surfaces to make the half-shells (A, B) snapping in the opening or in the closing position.
