<P>PROBLEM TO BE SOLVED: To provide an easily unsealable packaging body of which the quality is stabilized while satisfying both of sealability and easy unsealability. <P>SOLUTION: This easily unsealable packaging body 1 is equipped with a container body 10 for which a flange part 14 is formed on the peripheral edge of the opening 13, and a lid member 20 which is heat-sealed to the flange part 14 and closes the opening 13. Then, on the flange part 14, an inner peripheral side notch 15A and an outer peripheral side notch 15B which surround the opening 13 on the inner peripheral side and the outer peripheral side are respectively formed. Also, the flange part 14 and the lid member 20 are heat-sealed by a first sealing part 16A of a specified width which surrounds the opening 13 and is formed between the inner peripheral side notch 15A and the outer peripheral side notch 15B, and a second sealing part 16B having a narrower width than the first sealing part 16A, which is formed in a manner to surround the opening 13 along the first sealing part 16A within the region of the first sealing part 16A. In addition, the second sealing part 16B has a protruding sealing part 17 as a part which protrudes to the outside more than other parts at a location corresponding to a tab 21. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
