<P>PROBLEM TO BE SOLVED: To provide a lid material using no aluminum foil for a container with a flange capable of holding an opening condition and a re-sealing condition. <P>SOLUTION: The lid material using no aluminum foil covers an opening part of a container body (20) with the flange, and is hermetically sealed on the flange part (21). The lid material (10) is equipped with a tab (11) partially projected from the flange part, and a hook part (12) partitioned and formed by a notch line (a) is provided near the tab. The hook part is formed into approximately a U shape, and the lid material is formed by laminating at least a sealant layer (1) and a surface substrate (2) arranged on it through an adhesive layer (3). The hook part and its surrounding are formed by forming an easily releasable layer (4) for the adhesive layer (3). The notch line (a) is formed so as to pass through the sealant layer (1) and to reach the easily releasable layer (4). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
