<P>PROBLEM TO BE SOLVED: To provide a lid with a barrier property which is remarkably excellent in the barrier property, a stable sealing property to a cup and an easy unsealability as compared to a conventional one and makes unsealing more intelligible. <P>SOLUTION: The lid comprises a lower layer 4A comprising an innermost layer 7 having a polyethylene sealant layer 8 at least at the lowest layer and a metal foil layer 10 and an upper layer 4B which is peelable from the lower layer 4A. A plurality of lines of weak strength sections 13 are arranged at least at the innermost layer 7 of the lower layer 4A. The upper layer 4B is peelably separated from the lower layer 4A, and in use the lower layer 4A is torn at the weak strength sections 13 so as to facilitate unsealing. <P>COPYRIGHT: (C)2010,JPO&INPIT |
