Patent ID: 7874450

Claim:
A lid for a beverage can, comprising: a panel radius portion extending radially outward from a center panel portion; a panel wall portion; a chuck wall radius portion; a chuck wall portion; and a curled portion, wherein, when a contact point of the chuck wall portion and the chuck wall radius portion is taken as a first contact point and a contact point of the panel wall portion and the chuck wall radius portion is taken as a second contact point, the chuck wall portion is connected to the chuck wall radius portion so that a tangential line at the first contact point is inclined to a radially inner side of the center panel with respect to an axial direction of the center panel, and the chuck wall also extends along the tangential line at the first contact point and is bent at a predetermined bending radius to the radially outer side of the center panel with respect to the axial direction of the center panel, connecting to the curled portion, and wherein, (h 1 ) denotes a height of a center of a first radius portion within the chuck wall portion connecting to the chuck wall radius portion measured from a lowest point of the chuck wall radius portion, and (Δ 1 ) denotes a difference (amount of inner overhang) between a farthest point of the chuck wall radius portion and a closet point of the first radius portion with respect to the radial direction of the center panel, wherein conditions of 0<Δ 1 <1.4 and 0.5<h 1 <4.5 are satisfied.
