Abstract
PURPOSE:To improve a functional aspect, by preventing the upper surface of a bordering part from covering the surface of a lid plate from the opening part thereof and thermally bonding a release piece having a resin film applied thereto to the upper surface of the bordering part positioned inside the opening part. CONSTITUTION:When a metal foil is used as the base material 11a of a lid body 11, a thermosetting resin film 11b is formed to the outer surface of the base material and a thermoplastic resin film 11c is formed to the inner surface thereof. A resin bordering part 13 having an L-shape cross-section is integrally molded to the peripheral edge of the opening part 12 formed to the lid body 11 at a predetermined position with respect to the inner surface film 11c of the lid body 11 and the inner surface of a release piece 14. The horizontal protruding part in the bordering part is set to the anchor 13a brought into contact with the inner surface of a lid so as to cover the opening end surface of the lid body 11 by the L-shaped bordering part 13 and, at the same time, to develop sufficient yield strength exceeding the release stress applied to the release piece 14 and the top surface of the vertical part 13b integrally formed along with said protruding part is set to the adhesive surface to the release piece 14. Therefore, when the release piece 14 is peeled off, the bordering part can be left to the opening part of the lid in a perfect shape.
