Description of the Related Art Conventionally, as known from Japanese Utility Model Laid-Open No. 4-35576, a flammable container having a container body made of a paper-based material has been adopted in place of a metal can such as tin or aluminum. Now, we are trying to reduce the pollution by facilitating the disposal by combustion. In this case, at the joint portion between the container body and the lid, etc., thin resin outer layers such as polyethylene coat coated on the outer layer of paper material are butted against each other, and the whole container is passed through a high temperature heating furnace to form the resin layer at the joint portion. Is melted, or an adhesive is interposed in the joint to fix the joint, thereby joining the joints together and sealing the joints.

There is a problem that becomes.

ラルに沿って逃げ易く、この問題が顕著に現れる。Focusing on induction heating technology using high frequency waves, the induction heating coil is placed close to the joint, and local heating treatment is performed through a thin metal inner layer such as aluminum foil laminated on the base material. However, even if the induction heating coil is simply placed close to the joint and the coil is operated, the effective magnetic flux cannot be effectively concentrated in the thin metal inner layer near the joint, resulting in sufficient heating. It is difficult to secure sufficient welding strength because the amount cannot be obtained, and if the heat treatment time or the output of the coil is increased, problems such as deformation of the container body and burning will occur. In particular, when a spiral can in which a plate body is spirally wound around the container body is used, heat easily escapes along the spiral, and this problem becomes remarkable.

Another object of the present invention is to provide a method for manufacturing a flammable container and the like, which can firmly fix and seal parts in a short time.
