PROBLEM TO BE SOLVED: To prevent the mischief during the distribution stage, guarantee the quality of a content and rationalize the filling work thereof. SOLUTION: In a sealing method, a sealing material 26 is held temporarily by static elasticity on the inner surface side of a cover 20, and the cover 20 is mounted on the upper section of a container main body filled with its content, and heat is applied from above by a hot plate. The sealing material 26 is bonded on a colored section 12 of an opening edge 11 of the container main body by a hotmelt agent on one surface of the sealing material 26, and the sealing material 26 is bonded on the inner surface of the cover 20 by a blend layer on the other surface of the sealing material 26 by the arrangement, and at that time, the bonding force of the hotmelt agent is set larger than the bonding force of the blend layer. |
