The upper end part of the casing 1 and the surface element or the outer peripheral part of the ring 2 and the inner peripheral surface of the cylindrical part 13 of the cover lid 6 are heat-sealed to hermetically bond the container 5 and the cover lid 6. Therefore, material cost can be reduced by quantity capable of omitting an inner lid and sealing labor can be reduced.;COPYRIGHT: (C)1996,JPO
