<P>PROBLEM TO BE SOLVED: To provide an easily-unsealable container lid with excellent unsealability, which can reduce a force required for pulling out a plug member from an opening in unsealing. <P>SOLUTION: This easily-unsealable container lid comprises a lid member 31 which is equipped with the pre-formed opening 32, and an unsealing tab which is applied to the outer surface side of the lid member in such a manner as to cover the opening and adhere to the periphery of the opening in a hermetically sealed state. The unsealing tab comprises: a flexible member 1 which is composed of a sealing part bonded and fixed to the outer surface side of the lid member, and a folded part 4 continuing into the sealing part via a folding line 3; and the plug member 20 which can be fitted into the opening bonded to and integrated with the sealing part. Before the plug member is pulled out from the opening, the sealing part and the lid member, which are bonded together, are separated from each other or less tightly bonded together near both ends of the folding line. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
