As described above, the laminated sheet is welded and fixed to the plug plate with its peripheral end surface covered with the plug plate.
In addition, since the synthetic resin film of the laminated sheet has compatibility with the synthetic resin material which is the molding material of the plug plate, when forming the plug plate using the laminated sheet as an insert material, the lower side of the laminated sheet is formed. The synthetic resin film and the plug plate are firmly and densely welded, whereby the peripheral edge of the laminated sheet is completely covered by the plug plate. For this reason, the aluminum foil on the peripheral end surface of the laminated sheet is completely covered, and the occurrence of inconveniences such as corrosion of the aluminum foil and deterioration of the content liquid due to exposure of the aluminum foil can be eliminated.

The plug plate body having the laminated sheet welded to the lower surface is made of a synthetic resin material which is easily broken, so that it tends to have low heat resistance, and is therefore thermally deformed by the heat of the heat-filled content liquid. Although there is a danger, even if thermal deformation occurs in this plug plate body, the close contact function between the plug plate body and the upper end surface of the barrel does not decrease, so the cap body assembled cylinder to the barrel is As long as the push-down force by assembling acts on the plug plate, the peripheral edge of the plug plate is kept in close contact with the upper end surface of the barrel, and the sealing function between the barrel and the plug plate is maintained. Is not lost.
