Lid for containers of substances, and container of substances comprising said lid

A lid for a metal container able to contain a substance, comprising:

• a closing cap defined by at least one incision line, able to allow the closing cap to be lifted and at least partly torn,
• an opening lever disposed astride the incision line and comprising a front fulcrum end and an intermediate region provided with a flexible tongue attached to the closing cap,
• a mechanical connection located in proximity to the incision line, configured to mechanically attach the flexible tongue to the closing cap and configured to cooperate with said flexible tongue,
• said incision line having at the front, in the zone where the closing cap starts to be lifted and torn, a portion protruding outward, toward the front fulcrum end of the opening lever,
• wherein said protruding portion has, on both sides, segments of the incision line which move away from said mechanical connection as far as respective deformation zones, caused by compression of the incision line;
• further comprising an anti-breaking line positioned around said incision line, and further wherein said anti-breaking line is shaped so as to follow the profile of the incision line at least in a zone of the closing cap comprised between a rear flap of the closing cap and the zone of the closing cap where said mechanical connection is positioned and
• wherein said anti-breaking line and said incision line are connected in proximity to said rear flap of said closing cap by terminal branches.

• and
• further comprising a reinforcement edge defined by at least a first reinforcement line and by at least a second reinforcement line, and wherein said first reinforcement line is a closed line which completely surrounds the incision line, and further wherein said first reinforcement line has a connecting arch, said connecting arch having a radius of curvature of about 1.5 mm to about 2.5 mm.
