ABSTRACT:
A sealed, seamless box (10) that forms an RF-wave- or gas-tight enclosure is disclosed. The box of this invention includes a box body (12) formed of a single metal sheet (23) with a base panel (16) and upwardly extending side panels (18). The side panels are provided with tabs (20) that are thinner than the basic metal sheet. The tabs are seated in complementary cutouts (22) formed in the adjacent side panels. The cutouts have a depth equal to the tabs so that the side panels have a substantially uniform thickness equal to the thickness of the basic metal sheet. The tabs are secured in place by pins (30) formed integrally with the tabs that extend into openings (32) formed in the portions of the adjacent side panels that define the cutouts.
