Document Type and Number:
Japanese Patent JP2022119586
Kind Code:
A
Abstract:
To provide a can lid which suppresses deformation of a tab hole and prevents a tab from coming off a can lid main body, and to provide a manufacturing method of the same.SOLUTION: A can lid includes: a can lid main body which is attached to an opening part of a can body and is formed of an aluminum alloy having an opening piece partitioned by a score on an approximately disc-shaped panel part; and a tab for opening a can to open the opening piece. A rivet, which protrudes from the panel part and fixes the tab for opening a can between the panel part and a rivet head, is formed on an inner side of the panel part. A reinforced part, which is deformed by compressing or bending the tab for opening a can in an annular area surrounded by an outer peripheral edge of the rivet head and a circle with a diameter larger than an outer diameter of the rivet head by 1 mm, is formed at least in a range of 45° on both sides of a linear line extending toward a tab nose contacting with the opening piece of the tab for opening a can from a center of the rivet in a plane view of the can lid main body.SELECTED DRAWING: Figure 3
