Opening and pouring device including volume pouring spout for a container for a liquid and metal cover containing same

A cover and cover opening and pouring device for a container of a liquid, wherein said cover (A) is made of metal and is provided with an openable protective cap (6) defined by a precut perimeter (7) in said metal and a central rivet (8), and wherein said opening and pouring device comprises a metal hand lever riveted to the cover (A) acting as means for opening said cover by staving in said protective cap (6) and wherein said metal hand lever includes a volume pouring spout (1) acting as a drive arm thereof for staving in said protective cap (6) thus opening the container and comprising 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 of the open clipping ring (12), a riveting tongue (3) connected to the volume pouring spout (1) provided with a riveting hole (5) through which said rivet (8) is inserted and riveted to attach the hand lever to the cover (A), a hammer (2) integrated in the hand lever, acting as resistant arm of the metal hand lever and provided with a reinforced nose (10) for staving in the protective cap (6) along said precut perimeter (7) during an initial period of radial rotation of the metal hand lever and means for facilitating radial rotation of said hand lever comprising a strip (11) of spreadable excess metal provided as an integral part of the riveting tongue (3) and situated between the riveting hole (5) of said riveting tongue (3) and a side of the hammer (2) opposite the staving nose (10), so that after staving in the protecting cap (6) by rotation of said hand lever about a sliding rotation axis and 180.degree. maximum angular rotation of the hand lever about the sliding rotation axis, the pouring spout (1) is placed in an operating position by clipping by a pressure said open clipping ring (12) exactly in an opening in the cover (A) provided by staving in the protective cap (6) and the hammer (2) then passes under an inner face of the cover (A) after spreading of the strip (11) of excess metal.

A container for a liquid comprising a cylindrical metal container body (B) and a metal cover (A) on the container body and provided with an opening and pouring device,

• wherein the metal cover (A) includes means for stacking comprising a raised rim (14) around the outer periphrey thereof, is provided with an openable protective cap (6) defined by a precut perimeter (7) in said metal cover and includes a central rivet (8);
• and
• wherein said opening and pouring device comprises a metal hand lever riveted to the cover (A) acting as means for opening said cover by staving in said protective cap (6) and wherein the metal hand lever includes:
• a volume pouring spout (1) acting as a drive arm thereof for staving in the protective cap (6),
• a lip (L) to facilitate pouring and an open clipping ring (12) provided with a clipping flange (13) of semicircular cross-section consisting of an outer lateral thickened portion of the clipping ring to facilitate securing the pouring spout (1) in an opening formed in the cover (A) by staving in the protective cap (6),
• a riveting tongue (3) connected to the volume pouring spout (1) provided with a riveting hole (5) through which said rivet (8) is inserted to facilitate the riveting of the hand lever to the cover (A),
• a hammer (2) integrated in the hand lever, acting as resistant arm of the metal hand lever and provided with a reinforced nose (10) for staving in the protective cap (6) along the precut perimeter (7) during an initial period of radial rotation of the hand lever, and
• means for facilitating radial rotation of the hand lever comprising a strip (11) of spreadable excess metal provided as an integral part of the riveting tongue (3) and situated between the riveting hole (5) of the riveting tongue (3) and a side of the hammer (2) opposite the staving nose (10);
• so that, after staving in the protecting cap (6) by rotation of said hand lever about a sliding rotation axis over a 180.degree. maximum angular rotation of the hand lever about the sliding rotation axis, the pouring spout (1) is placed in an operating position with the lip (L) bearing on the raised rim (14) of the cover (A) by clipping with a pressure the open clipping ring (12) exactly in the opening formed in the cover (A) provided by staving in the protective cap (6) while by passing the hammer (2) under an inner face of the cover (A) after spreading of the strip (11) of excess metal.
