PROBLEM TO BE SOLVED: To provide a can body capable of suppressing the unexpected opening of the can body on a lower stage when stacking the can body whose internal pressure resistant strength is increased.SOLUTION: In a can body, equations such as L=D cos(θ1-θ2), A=X (L+Y1-Y2)/Y1 and B=L+Y2-Y1 are defined in a condition of E<Z and (A+B) E/Z<1.88 is satisfied in a condition of 0<L<Y2 (where, D is a distance from the tip of a tab to the surface of a can lid; E is a distance from an intersection part e between a perpendicular descending from the tip of the tab and the surface of the can lid to the seaming panel top part g of the can lid; θ1 is an angle between a linear line connecting the intersection part e to the seaming panel top part g and the perpendicular; Z is a distance from the grounding part a of a leg part 31 to the lower end b of a can barrel being in continuous contact with the outside of the leg part; θ2 is an angle between a linear line connecting the grounding part a to the lower end of the can barrel and the perpendicular; Y1 is a distance from the bottom d of a recess 32 to the lower end c of the recess; Y2 is a distance from the bottom d to the grounding part a; and X is a distance from a perpendicular passing the lower end c of the recess to the bottom d).SELECTED DRAWING: Figure 3 |
