FIELD: packaging industry.
SUBSTANCE: invention relates to a easy-open lid (10) intended for containers (cans) with food or drink and having a central panel (27) surrounded by an annular groove (16), and a peripheral roll-up panel (17). In addition, the lid structure includes a tongue (11) fixed to the central panel by means of a rivet (12) which is formed in the central panel (27) so that raising the tongue (11) beyond the radially inner portion causes the tongue spout (24) contact with the central panel in its area, adjacent to the radially inner edge of the annular groove (16), wherein said contact leads to breakage of groove. In the central panel, a roller (19) is formed, bending around the said panel within the circumferential groove (16) adjacent to it and having a radius greater than the distance of rivet (12) from the center of lid. At the same time, when achieving the zone, in which the rivet (12) is formed, the roller deflects inward from its annular path and terminates with fitting to the corresponding rivet sides.
EFFECT: reducing the blistering effect, additional strength when reducing the thickness of metal plate from which the lid is made is minimal.
