Abstract
PURPOSE:To eliminate the breakage of container sealings and attain a stably easy opening of a container by making a sealing strength between the flange of the container and a lid larger than a given laminating strength between a container seal layer having a given thickness and its adjoining layer. CONSTITUTION:In a container 1 sealed with a plurality of layers, a seal layer 5 has a thickness of 10-70mu and a laminating strength between the seal layer 5 and its adjoining layer 6 is within the range of 300-2000g/25mm. A sealed container is formed by sealably pressing a flange portion 3 of a container 1 against a lid 2 with a seal layer 5 and a seal layer 7 arranged in contact with each other interposing the film materials of both the container 1 and lid 2 and with heat applied thereto. When pulling up an opening holder 12 of the lid 2 with the fingers, since the sealing strength of a seal portion 9 between the container seal layer 5 and the lid seal layer 7 is larger than the laminating strength between the container seal layer 5 and the adjoining layer 6, the container seal layer 5 of the seal part 9 is adhered to the lid seal layer 7 and, conversely, the seal layer 7 is separated from the adjoining layer 6. The seal layer 5 is then cut off an a recessed portion 4 to thereby open the lid from the container.
