<P>PROBLEM TO BE SOLVED: To provide an inner sealant for container mouth sealing which can be adhered efficiently to the container mouth through radiation of high frequency wave and a seal layer adhering to the container mouth can be easily pierced with the finger to cause the seal layer to be peeled off from the container mouth and to open the seal part. <P>SOLUTION: A re-seal layer comprised of a cardboard layer and a polyolefine layer, and a seal layer comprised of a release layer, a biaxially oriented film layer, aluminum foil layer and heat adhering resin layer are adhered to each other in a manner that they can be peeled off. This inner sealant for container mouth sealing is constructed such that the biaxially-oriented film layer of the seal layer is formed with a piercing means comprised of either a slit or a group of scratch marks formed in a linear manner. <P>COPYRIGHT: (C)2004,JPO |
