<P>PROBLEM TO BE SOLVED: To prevent a container body from being dented inwardly when filling a substance subjected to the heat shrink caused by the temperature drop such as grease. <P>SOLUTION: In the grease storage method, grease is filled in a can barrel 5 in which a ground plate is seamed in a can bottom part, and an opening part 2 is formed in an uppermost part, and the opening part 2 is closed by a top lid 7. A circumferential edge groove part 9 is superposed on a fixed edge part 3 of a curved shape which is wind-projected outside the opening part 2 in the can barrel 5, and the opening part 2 is closed by locking the fixed edge part 3 in a packaging manner by a plurality of lugs 21 extending from the circumferential edge groove part 9. In the circumferential edge groove part 9, packing is not filled therein, and a projecting part 11 projected from a top part at the inner part is brought into contact with and supported by the fixed edge part 3, and the lid is closed to form a cavity 26 between the circumferential edge groove part 9 and the fixed edge part 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
