Claims (1)

[Claims for Utility Model Registration] (1) A tearing cut line formed on the lid body is torn by pulling a tab fixed to the lid body at a position inside the cut line, and the above cut line is torn. In a can lid that opens a portion surrounded by a line, the above-mentioned incision line is connected to an outer circular arc line portion located on the outer periphery of the lid body and extending from both ends of this outer circular arc wire portion toward the center of the lid body. a pair of outer line parts; an inner line part extending from the end of one outer line part to the outer periphery of the lid body between the pair of outer line parts; and the inner line part; an inner circular arc wire section extending from the end of the inner arc wire section along the outer arc wire section at a distance from the outer arc wire section toward the center of the lid body; 1. A can lid characterized in that an inner return line part is formed that extends in an arc shape from the inside of the inner arc line part in a direction opposite to the tearing direction. (2) Claim 1 characterized in that an outer return line part is formed at the end of the other outer line part, extending in an arc shape from this end outward from the other outer line part in a direction opposite to the tearing direction. The can lid described in . (3) The part of the inner line part facing the end of the other outer line part is formed into an arc shape convex toward the other outer line part, and the radius of this arc is set to 4 mm to 10 mm,
The other outer line part facing this arc-shaped part is formed into an arc shape convex toward the inner line part, and the radius of this arc is set to 4 mm to 30 mm, and the arc radius of the inner circular line part is set to 4 mm to 30 mm. 3. The can lid according to claim 1, wherein the can lid is set to 2 mm to 10 mm. (4) Tear the tearing cut line formed on the lid body by pulling the tab fixed to the lid body at a position inside the cut line, and open the part surrounded by the cut line. In the can lid, the cut line is formed by forming an outer circular arc line portion located on the outer periphery of the lid body, a first outer line portion extending from one end of the outer circular arc wire portion toward the center of the lid body, and a second outer wire portion extending toward the center of the lid body from a position spaced apart from the other end of the outer arc wire portion toward the center of the lid body; A can lid characterized in that a return line part is formed at an end of the second outer line part facing the other end part, the return line part extending in an arc shape in a direction opposite to the tearing direction between these ends.
