A can end lid for a can, in particular for a drink can, comprising: a lid plate made of a sheet material and including an upper side and an underside and a peripheral wall that surrounds the upper side of the lid plate, and in which, between the peripheral wall and a fixing stud disposed on the lid plate, a break-away area with a break-away portion is formed, the break-away portion circumferentially defined, at least predominantly, by a predetermined break-line, and an opening tab made of a sheet material and including a press portion and a grip portion and being rotatably attached to the fixing stud by means of a fastening tongue that is formed to the press portion within a cutout of the opening tab between the press portion and the grip portion, wherein a downward protruding sealing attachment with a sealing rim, that extends, closed in itself like a ring, along the outer circumferential contour of the sealing attachment, is formed on the underside of the plate-like grip portion by a recessed area depressed from the upper side of the grip portion, so that the press portion, in the opening rotating position of the opening tab, can be pressed down to separate the break-away portion from the lid plate along the predetermined break-line and create an aperture in the lid plate, and that the aperture can be sealed again by the sealing rim of the sealing attachment by pressing down the grip portion into a sealing position after rotating the opening tab around the fixing stud into a closing rotating position, wherein a ring-wall, that is as to its heigth at an angle to the upper side of the lid plate, extends around the break-away area of the lid plate, the ring-wall having an inner circumferential contour along its inner face that is closed in itself like a ring between the fixing stud, mounted outside the circumferential contour of the ring wall, and the peripheral wall of the lid plate, and the ring wall surrounding a recess with a bottom, in which the break-away portion is formed, characterized in that the break-away portion on the bottom of the recess is bordered by a ring shaped inner angular edge and a radial clearance is provided between the contour of the predetermined break-line, surrounding the break-away portion, and the inner contour of the ring-wall, so that a flange-like inner edge is created on the bottom of the recess surrounded by the ring-wall, and the closed ring shaped inner angular edge is formed jointly by the flange-like inner edge and the bottom edge of the inner face of the ring-wall, and wherein the sealing rim of the sealing attachment of the opening tab as to the outer circumferential contour of the sealing rim is shaped complementary to said inner circumferential contour of the ring-wall and engages on the inner surface of the ring-wall along said outer circumferential contour of the sealing rim while the inner angular edge is overlapped by a ring shaped outer angular edge of the sealing attachment of the grip portion, when the grip portion is in the sealing position. a lid plate made of a sheet material and including an upper side and an underside and a peripheral wall that surrounds the upper side of the lid plate, and in which, between the peripheral wall and a fixing stud disposed on the lid plate, a break-away area with a break-away portion is formed, the break-away portion circumferentially defined, at least predominantly, by a predetermined break-line, and an opening tab made of a sheet material and including a press portion and a grip portion and being rotatably attached to the fixing stud by means of a fastening tongue that is formed to the press portion within a cutout of the opening tab between the press portion and the grip portion, wherein a downward protruding sealing attachment with a sealing rim, that extends, closed in itself like a ring, along the outer circumferential contour of the sealing attachment, is formed on the underside of the plate-like grip portion by a recessed area depressed from the upper side of the grip portion,
