Abstract:

To provide a can body which has an excellent internal pressure inspection bearability and improved deterioration delectability and in which the bottom of the can body has a pressure strength which can withstand a rise in the internal pressure at a retort treatment and a two-piece can with thin wall can be applied to the contents of a can needing retort sterilization.

In the can body, an annular ground-contact part 3 is formed near the outer periphery of a can bottom and a substantially flat part is provided within the part 3. And contents are charged into the can body and sealed under such a low positive pressure that the internal pressure of the can body at room temperatures is 0.2-0.8 kgf/cm2, preferably 0.2-0.6 kgf/cm2, and variation is ±0.2 kgf/cm2, preferably ±0.1 kgf/cm2, and hammer test bearability can be provided at the flat part of the bottom.
