<p>PROBLEM TO BE SOLVED: To provide a can which can increase the strength without increasing the thickness of a sheet. SOLUTION: This can is provided with a tube shape body part 2, an annular grounding part 3, a button outer peripheral part 5 which connects the body part 2 and the grounding part 3 and whose diameter becomes smaller toward the grounding part 3 from the body part 2, a rising part 6 provided at the inner peripheral side of the grounding part 3, and a dome part 4 jointly provided at the standing part 6. The sheet thickness (t) of the bottom of the can is set 0.23 mm<=t<=0.29 mm, the outer diameter D of the can 51 mm<=D<=55 mm, the grounding diameter (d) of the grounding part 40 mm<=d<=45 mm, the height HS of the body bottom end 55 mm<=HS<=7 mm, the radius R7 of a curved part 7 which is an outward protrusion where the body part 2 and the peripheral part 5 are connected 2.7 mm<=R7<=3.6 mm, and the radius R6 of a curved part 8 which is an inward protrusion where the grounding part 3 and the outer peripheral part 5 are connected 7.5 mm<=R6<=9 mm.</p> |
