<p>PURPOSE:To perform the fusion bonding of a lid to a bellows type cylindrical container without generating an inferior place, by temporarily mounting the lid to the container in an inlaid state and heating the peripheral edge parts of the flange parts provided to the lid and the container while integrally rotating both of them and making the inlaid state deep to grasp and bond both flange parts under pressure. CONSTITUTION:A bellows type container A is received in a mold frame 13 and a coil spring 36 is inlaid with the container A while the inlay part of a lid B is temporarily inlaid with and mounted to the inlay part 36 of the container A. Next, peripheral edges and end surfaces of flange parts 38, 40 provided to the container A and the lid B are heated over entire peripheries thereof by a burner apparatus 44 while both of them are integrally rotated and the inlay parts 37, 39 are further deeply inlaid when bead like deformation begins to grasp and bond the flange parts 38, 40 under pressure.</p> |
