CANNED GOODS OF LOW POSITIVE PRESSURE HAVING INNER PRESSURE CHECKING ADAPTABILITY, AND CAN BODY OF THE SAME

摘要

A can body (1) of canned goods of a low positive pressure having inner pressure checking adaptability, wherein a trunk portion (2) and a bottom portion are molded seamlessly into an integral structure, the bottom portion having an annular seating section (3) in the vicinity of an outer circumferential part thereof, a part on the inner side of the annular seating section (3) constituting an inner rising wall (4) extending upward in the inward direction of the can body, a substantially flat bottom wall (6) being formed on the inner side of the inner rising wall (4) to a height larger than that of the seating position by 0.5-6 mm, goods being packed and sealed in the can body (1) in a low positive-pressure state so that an inner pressure at room temperature is 0.2-0.8 kgf/cm<2> and more preferably in the range of 0.2-0.6 with scatter of +/- 0.2 kgf/cm<2> and preferably +/- 0.1 kgf/cm<2>, to enable the flat portion of the bottom wall (6) to have a knock-checking adaptability.
