<p>The opening and pouring device is useful for a cylindrical liquid-containing container, particularly a metal beverage can, having a cover (A) provided with an openable protective cap (6) defined by a precut perimeter (7) in the cover (A). The opening and pouring device is a metal hand lever riveted to the cover (A) and acting as an opening device for staving in the protective cap (6). The metal hand lever includes a volume pouring spout (1) acting as a drive arm thereof for staving in the protective cap (6) and includes a lip (L) and an open clipping ring (12) provided with a clipping flange (13) of semicircular cross-section consisting of an outer lateral thickened portion for securing the pouring spout (1) in the hole formed by staving in the protective cap. The metal hand lever also includes a riveting tongue (3) provided with a riveting hole (5) and a hammer (2) acting as resistant arm and provided with a reinforced nose (10) for staving in the protective cap (6) as well as a strip (11) of spreadable excess metal between the riveting hole (5) and a side of the hammer (2) opposite the staving nose (10). Once the protective cap (6) is staved in, the base of the pouring spout is centered and is clipped in the hole left vacant by the protective cap after 180 DEG rotation of the hand lever on a sliding axis radial to the cover (A).</p> |
