<p>A magnetic closure device is configured to allow for a reduction in the magnetic gap as well as for adding mechanical strength to a cover for enclosing the magnet supply and other associated parts on one of two separate elements. The magnetic closure device includes a first element and a second element which are magnetically and mechanically coupled together and may be detached. The first element A includes an annular member formed to have a thick wall and mounted around the cover. The annular member includes ornamentation at its surface. The annular member may be formed from brass or other nonmagnetic materials, including plastics.</p> |
