<P>PROBLEM TO BE SOLVED: To provide a lid material in which a hole for passing a liquid therethrough can be formed, the appearance after opening the hole is superb, a paper piece is not fallen from an exposed surface after opening the hole, and the productivity is high, and a container using the same. <P>SOLUTION: The lid material has a surface layer 1, a polyethylene-based film layer 2 laminated in contact with a mixed resin layer 3 in which polyolefin and a cyclic olefin copolymer are blended at a predetermined ratio, and a sealant layer 5 located on a lowest part, and it is constituted of a laminated body in which an interface between the polyethylene film layer 2 and the mixed resin layer 3 is a peeling surface. An unsealing tab 50q and a hole-opening tab 50r are provided on a peripheral edge. A back half-cut 30a for forming a liquid passing-through-hole and a back half-cut 30b for connecting peripheral edges on both sides of the hole-opening tab 50r are provided in the vicinity of the hole-opening tab 50r from the sealant layer 5 side, and each back half-cut reaches the mixed peeling resin layer 3. <P>COPYRIGHT: (C)2008,JPO&INPIT |
