A pressurized metal can having a bottom comprising a panel connected with a panel radius (R4) to a countersink having a panel wall angle (A2), a foot wall angle (A1), and a countersink radius (R3), which countersink is connected to a foot having a foot radius (R2) and the foot is connected to a can body wall, which panel has a substantially non-concave form, wherein
- the foot wall angle (A1) is in the range of about 0 to 45°;
- a panel wall angle (A2) is in the range of about 0-45°;
- the foot radius (R2) is in the range of about 0.5 to 1.5 mm;
- the countersink radius (R3) is in the range of about 0.5 to 1.5 mm;
- the panel radius (R4) is in the range of about 1 to 1.5 mm;
- a unit depth (H1) is in the range of about 5-15 mm;
- a panel depth (H2) is in the range of about 2-10 mm;
- and
- a center panel radius (R5) is larger than about 20 mm,
- wherein the can has a diameter in the range of about 20-80 mm, a bottom thickness in the range of 0.2-0.7 mm, and a pressure resistance up to about 15 bar.
